nnitmrr. GEELHART, or nounnur, MONTANA.

Be it lmown that I, HERMAN M. GEEL- HART, a citizen of the United States, residing at Roundup, in the county of Mussel-' shell and. State of Montana, have invented certain new and useful Improvements in Y Track-Dressing Machines, of which the followingis a specification, reference being had to the accompanying drawings.

This invention relates to scrapers, and particularly to track dressing machines.

The general object of this invention isto rovide a track dressing ear or truck having laterally disposed rearwardly inclined scraping wings mounted thereon, and so formed as to shape the ballast on each side of the ties, shape the sub-grade, carry gravel into holes where gravel is lacking, make a perfect grass line at the proper distance from the rail on each side, and in a general way to form a uniform road bed.

A further object is to provide a scraper ofthis character which, while simple in construction, may be increased or decreased in length to thereby adjust it for different conditions of service, and further provide means whereby the wings or scrapers may be adjusted as a whole toward or from the car or lowered or raised into or out ofoperativ'e position.

A further object is to provide improved means for raising or lowering the scraper which may be operated by train line air pressure.

Still another object is to provide a brush mounted uon the forward end of the truck or car which will act to sweep gravel orballast off of the rails or top of the ties and to level the ballast between the rails of the ack I 'Still another object is to provide a scrape of this character with an auxiliary scraper which, when adjusted to operative positions, will assist the main scraper in giving the proper curvature to the face of the ballast laterally of the rails, which will bring gravel up toward the ties, shape the gravel at the'shoulder of the embankment, and drag gravel or ballast into low spots, and further to provide this auxiliary scraper with a forwardly extending blade which acts to hold the gravel, when there is an excess of gravel or ballast, in front of the aux iliary scraperso that the gravel will not be wasted any more than possible. Still another object is to make this auxil- TRACK-DRESSIN 'G MACHINE.

iary scraper foldable upon the main scraper so that it may be folded fiat upon the main scraper'when the machine is not inuse or where the'car is assin over bridges by any obstruction whic is -c oser than six feet to the track. l

A further object is to so mountv the rotatable brush upon the forward end of the car i or truck that it may be readily shifted by power into or out of operative position.

Other objects will appear inthe course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a side-elevation of a track dressing machine constructed in accordance with my invention;

Fig. 11 is a side elevation of the track dressing machine showing the scraper elevated and the brushelevated and in inoperative position.

As illustrated in the drawings, my track dressing machine includes a truck or car body designated generally A which may be of any suitable construction and which is mounted upon wheels designed to run upon the rails of the track.

the line 5- 5 of Disposed on each side of the truck, as illustrated in Fig. 2, is

amain scraper designated generally B which s made up of a plurality of sections,

as will be later stated, and each scraper being so mounted that it may be turned into parallel relation to the truck A or into angular relation thereto and being further so mounted that the scraper may be turned upward at their'rear ends, so as to carry the scrapers entirely out of operative position.

Each of these scrapers, as illustrated particularly in Figs. 2 and 4, is composed of three sections 11, 12 and 13. The section 11 is about fourteen feet long and has a height of about four feet at lts wldest part and .is preferably made of four inch oak reinforced with a sheet of boiler iron on each side. The section 12 is approximately ten feet long and has the same height as the section 11 and the same thickness and is preferably of the same construction. The section 11 overlaps the section 12. The sec tion 13 is four feet long and has the same which may be of any suitable length and bolts 16 are connected to the section 12 and pass through these slots 15 and thus by means of these slots and bolts, the total length of the sections 11 and 12 may be adjusted. These sections 11, 12 and 13 are held in angularly adjusted positions with relation to the truck by means of adjustable braces whibh will be later described and the forward en of the section 11 is pivotally connected to the truck, as illustrated in Figs. 4 and 5.

Midway of the length of section 11 is a vertically disposed strengthening iron 17 and the lower edge of the section 11 is' curved upward from the lower end of the iron 17 toward that end of the section 11 which is adjacent the car, that is, to the point 18. At the point 18, the lower edge of the section 11 extends upward and then extends longitudinally or forward so as to extend over the ties, then extends upward, as at 19, to clear the rail, and then again forward as at 20, so as to extend over the top of the rail, thus providing for about a half inch clearance between the head of the rail and the section 20. The curvature of the lower edge of the section 11 is the curvature given to the ballast on each side of the ties.

The section 13 is hinged to the section 12, as before stated, and the free end of the section 13 carries a relatively small scraper section 21 which is pivoted at 22 for free vertical movement, the free end of this scraper 21 being connected to the free edge of the section 13 by means of a chain 23. The sections 12 and 13 are designed to scrape and level the sub-grade on each side of the ballast line and the auxiliary stri 21 rises and falls as the occasion d'eman' s to level 05 what little ridge of dirt may be left by the scraper 13 and to slope the fill. This scraper 21 should be about one foot wide and in practice about four feet long. Attached to the section 11 near its middle is the auxiliary scra er 24. This scraper is hinged by means 0 pintle 25130 the outer face ofthe section 11 forward of the rear end of the curved under edge of the scraper 'and'this auxiliary scraper 24 when in use extends out at approximately a right angle to the face of the section 11. The lower edge of the'scraper 24 is downwardly and laterally curved as at 26 and the free end of the auxiliary scraper is connected to a rearwardly extending brace plate 27, the middle of which is cut away as at 28 and the free edge of this brace plate 27 is formed with spaced beads 29 adapted to be disposed in alinement with a bead 30 formed upon the member 17 and designed to receive a pivot pin or pintle 31, this pintle 31 being detachable so as to disconnect the brace plate 27 from section 11. The auxiliar scraper 24 and the brace plate 27 .are botfi formed with slots 32 to engage a staple 33 projecting from the member 11 so that when it is necessary to pass obstructions which are closer than six feet to the track, the auxiliary scraper and its brace plate may be turned flat against the section 11 and held in place by a locking pin passing through the perforation in the staple. i

Preferably the forward face of the auxiliary scraper 24 is provided with a sector shaped blade 34 which extends from the scraper 24 approximately at right angles thereto. The forward edge of this blade is upwardly and. forwardly curved. This aux iliary scraper is designed with the upwardly and inwardly curved edge of the section 11 to form the ballast line and to bring the gravel up to the ties. It further shapes up the gravel or ballast shoulder dragging the gravel from high spots to low spots and covers up or cuts off weeds. The blade 34 holds the gravel from too great lateral displacement in front of the scraper 24 and thus prevents the gravel from being wasted. The blade 34 also follows the rass line as it is termed, that is, the line of junction of the ballast with the sub-grade, and makes a clean line of demarcation between the ballast and the sub-grade. This blade 34, in practice, is approximately two feet, four inches in length. The auxiliary scraper 24 in practice will be about two feet nine inches in length. x

The section 11 at its forward end, as before stated, is pivotally mounted and it is necessary that this support or mounting for the section 11 shall be one whereby the scraper B may be angularly adjusted and may I preferably swivel the section 11 to a slide 35 mounted to have sliding engagement upon a vertical supporting column or .beam 36.

Theseslides are operatively connected to suitable actuatin means. Attached to the inner face of eac section. 11 is an annulus 37 and rotatable within this annulus and overhung thereby is a disk 38. Thus the section 11 may rotate around the disk 38. This disk 38 and the slide 35 are provided withoverlapping eye-bolts or like members 39 and a pintle 40' passes through these eyebolts and thus there is secured a pivotal en-- sired. Furthermore, the slide may be raised 7 or lowered to raise or lower the forward end of the scraper. I

The mechanism whereb the slides may be raised or lowered, prefera ly consists of cylinders 41, one for each slide, these cylinders being mounted iupon the truck and being connected b pipes 42 to a source of, air or steam or other fluid under pressure. Disposed in each cylinder is a piston, the iston rod of which is designated 43 and eac piston rod carries upon it a pulle 44. As

shown in Fig. 1, a cable 45 is attac led at one end to the frame of the machines, passes around this pulley 44, then extends forward under a pulley 46, then upward and over a pulley 47,, on the column 36, and then downward to the slide 35. This slide 35 is provided with a lockin bolt 48 and the column is formed with a plurality of perforations, as-illustrated in Fig. 4, with which the looking bolt 48 is adapted to engage so as to hold the slide adjusted and from other downward or upward movement while the scraper is in actual use.

Each scraper B is held in its angularl adjusted position with relation to the true by means of a plurality of pairs of braces 49, there being a pair of braces or set of braces for each of the sections 11, 12 and 13. The braces 49 are adjustable as to length and to this end I have shown these braces as being formed of telescopic sections, the sections being perforated at a plurality of points and the sections being held in their adjusted relation to each other by means of bolts or pins 50. These braces 49 are con nected to eye-bolts 51 projecting from the sections 11, 12 and 13 and from the truck. Preferably one of the braces 49 of each section is connected to the section at apoint lower down than the other brace 49 of the same section.

The several braces 49' are connected by asaaes s also be raised or lowered. To this end simply flexes to permit the raising Forthe pur ose of raismg each 7 their eye-bolts 51 to transversely extending beams 52. Preferably the longest braces,

that is, those braces which are used for the sections 13 are approximately ten feet, three inches in length when the sections of the braces are fully extended. This will permit the scraper or wing B to be adjusted for a five'foot gravel shoulder or a five and a half foot gravel shoulder. The remaining braces are enough shorter than the rearward braces as to permit the scraper or wing bead to V have an angle of forty five degrees .of the len h of the car.

ttached to the rear end of each section 11 at its upper edge by. means of an eye-bolt 53 is a cable 54 running from the eye-bolt 53 to an eye-bolt 55 on the column 36. This supports each scraper B in its proper-operative position when the scraper is lowered. When the scraper is raised, this cable 54 of the scraper. scraper there is provi ed a cable 56 which extends upward and over a pulley 58 mounted upon the frame of the machine in' any suitable manner, this cable then extending downward and beneath a pulley 59 as illustrated in Fig. 1, then around a pulley 6O carried by a piston rod 61 and then the end of the cable is attached to the frame of the machine, as at 62. The piston on-the rod 61 operates within an air cylinder 63' and it will be obvious that when this piston is 'moved inward the corresponding scraper will be raised. The cylinders 63 are sup plied with air by means of pipes 64, wherein are disposed the valves 65, and these pipes 64 and pipes 42 connect by a common header 66 to a supply pipe 67, which in turn extends to an air storage tank 68, illustrated as mounted adjacent the forward ends of the scrapers, this pipe being in turn supplied with air by a train line not shown.

Suitable controlling valves are provided to control the air passing from the storage tank 68 to the pipes 64 and 42 and it is obvious that the valves 65 and the valves I the rails and from the top of the ties and to level this gravel. Thus brush must be made so that it may be raised or lowered 7 and also must be mounted so that it may be shifted into or out of operative position and to this end I have provided the two vertical supporting beams 71 which are piv- 6271.. I reeaeee oted at 72 upon sliding blocks 73, these blocks moving on tracks 74 on the frame of the truck. The lower end of each beam 71 is vertically slotted as at 75 for the reception of a sliding bearing box 7 6 in which the shaft 77 of the brush rotates. This brush shaft carries a sprocket wheel which is connected by means of a sprocket chain 78' to a sprocket wheel on the shaft 79. This shaft 79, as illustrated in Fig. 2, is mounted in suitable bearings and extends transversely of the truck and is driven by means of a gear wheel 80 thereon, in turn driven by a gear wheel 81, mounted upon a shaft 82 having oppositely disposed cranked portions.

.This crank shaft is driven by means of a steam engine 83 which may be of any suitable character, as for instance, a Lidgerwood engine such as is ordinarily used in engineering practice. also carries upon it a winding drum 84 over which passes a cable 85 extending rearward over the pulley 86 and then upward and forward to a cross beam connecting the uprights 71. Thus it will be obvious that by rotating the drum, the frame.

formed of the members 71 and the cross bar thereof will shift to a horizontal position, as illustrated in Fig; 7. It will likewise be seen that the cable 85, after the brush supporting frame has been turned to a horizontal position, will act to shift the slide 73 and the brush supporting frame rearward to the position shown in Fig. 7, The slide blocks 73 are to be of a height sufficient so that the cross bar 71* of the frame formed of the member 71 will pass over the top of the cylinders'83. Of course it is to be understood that before the frame 71 can be turned to its horizontal position, the sprocket chains 78 are to be released from their engagement with the sprockets. The brush supporting frame may be held in its vertical position by means of braces 87 detachably connected to the beams 71 by removable bolts or any other suitable means may be used for de tachably holding the. beams 71 in their vertical positions.

The engine 83' will be supplied with steam by means of the pipe 88'. This may be connected to any suitable source of steam. The slides 73 are held in their adjusted positions when the beams 71 are vertical'by means of removable pins 89. When these pins are removed it permits the slides to shift rearward on the tracks 74 to the position shown in Fig. 7. While I do not wish to be limited .to any particular form of rotary brush, I preferably 'form the brush with radiating strips of metal about one-fourth inch thick and a half an inch wide, as illustrated in Fig. 10, these strips having suflicient elasticity to permit This crank shaft them to spread after they pass over the rails, the middle and end strips of the brush extending down and sweeping against the top surfaces of the ties.

The manner in which this machine is used is evident from what has gone before.- After the scrapers are adjusted outward to their full extent they will be disposed at an angle of about 45 degrees with the line of draft, but they may be disposed at less than 45 degrees to the line of draft depend- When the machine is out of operation the scrapers are turned up to an upwardly and rearwardly extending position by drawing inward on the cables 56. This movement is permitted by the swiveled connection between the scrapers and the truck. It will be notedthat when the scrapers are shifted to the position shown in Fig. 2, that the inner .ends of the scrapers extend inward over the rails. The auxiliary scraper 24 and the blade 34 are very important features of my invention for the reason that if these parts were absent the gravel or ballast carried along in front of the blade 11 would simply shift laterally and discharge onto the sub-grade and holes in the ballast shoulder would not be filled up. By providing'the parts 24 and 34 however a pocket is formed immediately in advance of that portion of the scraper which molds the ballast, and thus the surplus ballast which is scraped from the top of the ballast bed is not carried laterally beyond the ballast bed, but is held therein so as to fill up any holes that there may be in the ballast. Regardless of the length of the scraper, it is necessary to get the contour of the gravel or ballast absolutely correct and this being secured, the sections 12 and 13 form the sub grade regardless of the width of the subgrade.

While I have illustrated certain details of construction it will be obvious that these may be modified in many ways without de parting from the spirit of the invention. It will, therefore, be obvious, of course, that the body of the car with the several uprights, brace beams, etc., may be formed either of wood or of channel or angle iron and that these details of construction will vary depending upon the general construction of the car,
