To all whom 'it may concern."
Be it lmownthat L'Jmiis R. STEPHEN- soN, a citizen'of the United States, residing at Dayton, -in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Multiple Drills, of which the following is a specifica-y tion.
This invention relates to improvements in multiple drills and the particular object is to so construct the parts that each drill spindle may at any moment be connected with a separate and independent set of gears thereby making it possible to operate two or vmore drills at di erent speeds, and it is a 'further object to improve the supporting means for the different drill spindles. v
In the drawings, Figure 1 is a side elevation of the machine, partly broken away, so as to show the change s eed mechanism in vertical section. Fig. 2 is a detail view of the main driving shaft broken away at` its lower end. Figs. 3, 4, 5-and 6 are detail views of the supporting bracket for the spindle. Figs. 7 and 8 are detail views of the spindle. Fig. 9 is a top view of gears showin casing in section on line w :v Fig. 1. Fig 10 is 'a sectional view of the supporting brackets for the spindle.
Like parts are represented by similar characters of reference in the several views. Referring to Fig. 1, the frame or vertical standard for supporting the mechanism is indicated by A. The pulley B is the ordinary driving ulley, operated from any suitable source of) ower, and the ordinary and usual change o speed devicesmay be located in the lower art of the machine, so as to vary the speed) of the main driving shaft, a, which, in turn, is connected to thev pulley shaft in any usual way. The main'driving shaft, a, is supported in bearings a1 and a2 formed in the upper part of the standard A and theA supplemental casing A1, There are shown supported on the upper part of said driving shaft, a, three separate gears, a, a4,
and a5, and eachof these gears is connected to the main shaft, a by a -sliding`key, as hereinafter more fully explained. The largest gear ai: is located near the extreme upper end of the operating shaft, a, and same is shown in mesh with a small gear, b, which is formed Aintegral with a larger gear, b1, and these .two gears be, ing loosely Journaled on'the intermediate shaft b2. The gear a* likewise meshes with a gear loosely journaled onl the intermediate shaftz, but larger than the gear, b. So likewise the lowermost gear aon the main driving shaft, a., is shown in mesh with its associated gear on the.intermediate shaft b2.
whichl gear i s of different size", from the other connecting gear on said intermediate vshaft and thereby there is effected a change of speed through the different driving gears, b1, b3 and b, on said intermediate shaft. As shown in Fig. 1, the intermediate shaft b2 at its upper andlower end is supported and mounted in casing Az which is bolted to the standard A. As is apparent from Fig. 1, the casings A1L and A2 comprise a head' supported ongthe standard A and the gears are mounted within said head. There is likewise rigidly mounted within said head an additional` shaft b5 and loosely mounted on said shaft are three se arate gears of equal size, b, 57 and bs, which are shown in mesh with ytheir associated b, on the lintermediate sha parent that ball races or. analogous devices may be employed between the various gears, though I have not shown same in the drawings. A
The drill spindle is of the ordinary type formed of two parts, c and 01, these being upper and lower parts respectively, and these parts are connected together by 'an intermediate section '04. The upper part, c, is rotatingly mounted at its upper and lower ends within bearingsformed in the casing of the head, and thereis slidingly mounted on said s indle a small gear c2, andthe ordinary vs ifter 03 is adapted to shift said gear c? from the lowermost gear bs, to the next succeeding gear b? or to the gear b the parts being so shown in Fig. 1 that the gear o2 is in mesh with the gear bs, and in this way the small gear c2 can, at any moment, be Vshifted from one position to another, and thereby thespindle will be operated at a-dilferent speed.l It is to Ybe understood that each spindle is formed like the others,hence it is unnecessary to repeat explanations as to the construction of each spindle, excepting to state that there is a tgear, b1, b3 and b2 It is ap-n sliding' gear c for each spindle, adapted to mesh with any one'of the three gears b, b", b'. In this manner, it is permissible to drive one siindle by means of the lowermost gear s while the companion spindle may be driven by means of the gear bT orl the gear b, so that it is unnecessary always to drive the different spindles at the'same speed, but, on the contrary, one spindle may operate all of the spindles at the same speed,
' d10 fit within the other-two sets of gear mechanism could well be dispensed with and t0 this end there are shown devices for throwing out of com- -mission each set of gear.
Referring to Fig. 2, the lowermost gear, a", is connected to the driving shaft, a, by the key, d, and the shifter rod, d1, is formed with a hook at its u per end "so that said shifter rod, d1, may Lbe lifted to move its key, d, so that the gear, a5, will no longer be connected with the driving shaft, a. Likewise the gear a4 is associated with a sliding key, cl2,- which is controlled by the shifter rod d3, and the gearar,3 has a similar key and shifter. The bracket or support, d4, (Figs. 3 and 4) is formed with the usual slot d5 and thereby is adjustabl supported on the casing, A2 by the bolts 0, (see Fig. l) in the usual and ordinary way. Said bolts grooves formed in the casin A and the heads of the bolts are supporte by ledges formed in the casing as clearly shown m Fig. Land as is quite usual in this -kind of machinery. The Shanks of the bolt project below the casing and are readily fitted into the slots di' and nuts are then applied to the ends of the Shanks so as to support the bracket d* immediately below the casing A2. At the free end of the bracket d* there is shown a peculiarly formed recess, al, which extends throughout the end of said bracket, and there is adapted to be tted within said recess a member, (Z7, which is formed witha shank, da, adapted to be slidingly mounted withln said recess, d, and thereby same may be adjusted within said recess and held in adjusted position by screws or an approved means. The lower section, c1, o the drill spindle, is supported within the hole Z9 formed in the member d". The drill itself is adapted to be fitted within the socket, d, formed in the lower end of the lower section c1.
The work table is shown located below the spindles. The various parts of my machine are shown to be so arranged as to present a more effective machine than heretofore known. 1
