ELEVATOR.

'sponsoren inea .epm 1e, ieee. serial no. 102,274.

This invention relates'to new and luseful im )rovements in an elevator.

, a novel `type of elevating apron 'employed and a novel type of stacking l, apron, asso-l ciated therewith.

A further feature of the invention resides in the provision ol a power unitadJustably mounted on the elevator :tra-me, for the pur-- poses hereinafter s eeied.

A. still further sature ot the invention resides in the provision of means for anchoring the elevator 'in position on the supporting floor to hold the same steady while 1n operation.

With the above and other objects 1n View this invention has particular relation to een A.tain novel features oit construction., operation and arrangement of parte, an ena or" which is given in this" specification an illustrated in the accompanying drawings, wherein Figure 1 shows a sideelevation of the elevator, partly in section.

Figure 2 shows a cross sectional view thereof, taken on the line el-2 of Figure 1.

Figure 3 shows a cross sectional view thereof taken on the line 3-3 o`li Fi ure l.

Figure Il shows a plan view ot t e elevator frame, showing a sectional view ot the apron frame pivoted thereto.

Figure 5 shows a rear elevation of the elevator, partly in section.'

Figure 6 shows a plan view of the steeltin apron employed, and

connected at one end by means of the chennel iron 2. At their other ends these side members have bearings 3, 3, in which the transverse shaft 4 is mounted.

There is an elevating apron frame formed with the side members 5, 5, of channel' irons whose lower ends having bearings onthe sha-ft 4 adjacent the 'inner ends ofthe respective bearings 3. The upper ends of the side members 5 are supported b the adjustable supporting links, designate generally by the numerals 6, 6.

Each supporting link comprises arf upper and a lower channel irondesignatedfby the numerals 7 and 8 the former of which are pivoted to the respective side members 5 and the latter of which are pivoted to the respective side members 1, by means of the crosssrods 7 and 8 respectively which exlLocalit*through the si'de'members 5, 5, and 1,

I'1l@espectively and through the adjacent ends of thecorrespondin channel irons 7 and 8. ,'lfhe channels 7 an 8 face cach other, with their ends overlapping and their respective .side flanges abutting.'` The free ends of the channel 4irons 7 and 8 have the blocks 9 igure 7 showsan enlarged fragmentary' side view of the delivery end of the elevatlno apron frame.

rring now more particularly Ato thedrawings, wherein like numerals of reference designate similar parts in each of the ligures, the numerals l, LTl designate the sido members of the elevator trame, which are bolted thereto, each adapted to run in the channelof the opposite iron to hold said irons'in alignment. There is auack 10 bolted to the back side of cach channel 7, said racks being in mesh with the respective spur gears 1l which are fixed on the transverse shaft 12, mounted in turn in aligned bearings carried by the channel irons 8. One end of the shaft 12`has a screw ear13 fixed thereon which is in mesh wit the Worm .14 which is fixed on the crankshaft 15;

turning the crunk shaft thek elevating` apron 'trame ma be lifted or lowered.

The elevator ramework, above described is mounted on the carrier wheels'l, 16, and underneath the front ends of the` side members 1 are the castors 17, 17. vWhen in use the elevator is su ported on said .wheels and ' castors 16 and 1 and to anchor it. against movement, outwardly threaded anchor rods 18, 18, are threaded through the flanges of the brace 2 and their lower ends are pointed to engage said floor. L

The upper ends of these rods have' the removabler cranks` 19, by means ofiw which they 'mayffbe manipulated. When it is desired to iove the elevator the feds 18 may be turned to withdraw them from the floor and vthe entire elevator then moved about,

. or turned, on the Wheels 16.

`,has a spur gear 36 Bolted tothe upper ends ot the side Incinbers are the brackets 20. 20.*which have transversely aligned adjustable bearings 21., 21, in which the transverse shaft 22 is mounted to rotate. .This shaft 22 carries spaced sprocket. wheels 251. 23, which are xed thereon and are in alignment with the sprocket wheels 24,24, which are fixed on the shaft 4 andoperating over these aligned sprocket wheelsA are the chains 25, 25, which have the transverse spaced slats 26 whose ends ride upwardly as indicated by the arrow in Figure 1, on theupperedges or faces, of the side members 5, and thus Aform the elevatingapron. The under side of this apron is enclosed and protected by the hood 27, which is swung from the side members 5, by the brackets 26. l

Slidably mounted on the side nxenibcrs 1. l., there is a motor frame comprising the angle shaped side bars 29, 29, which are connected by the U-shaped suppprting brackets 30. 30, on whichthe motori-31' mounted. The motor shaftcarries a tixeih pinion 32 which is in mesh with-a spurgcar Wheel 33 which is fixed on a transverse shaft 34. This shaft is mounted to rotate in . bearings 35, 35, carried bv the side bars 29 and v Xed thereon which is in jmesh with the gear 37 fixed on'the shaft 38 which rotates ,in bearings 39, 39. also carried by the side barsl29. The shaft 38 has .a'xecl sprocket wheel 40 aligned with a corresponding sprOQlfet-vwheel 41 ixedron the shaft Land aY clain42 operates over these i sprockets and transmits rotation from the former to the latter.

The motor 31 and the transmission gearingassociated therewith and mounted on the motor frameare movable, as an inde* pendent unit, on the elevator frame. Fastened on the side members 1, 1,'"adjacent ,-their'fcrward ends are the tapped bosses 43, 43, with the jack screws 44, 44, threaded 'through them and abutting the respective bars 29, 29. Through these screws the motor frame'may be adjusted to regulate the tensio'non the chain 42. The tension on the elevator chains may be likewise adjusted through the take up screws, as 45, which are threaded throughthe webs, as 46, and abut the respective bearings 21.

' The numeral 47 designates a. delivery, or stacking apron, or platform. This apron is substantially rectangular and it is supported on the spaced arms 48, 48, whose free ends are formed with- bearings 49, 49, adapted to receive the shaft 22. Between the arms 48 there is a delivery roller 50 mount underneath, bearing members fastened to the 'la-ttor to the toi-mer.

This),,apparatus is particularly adapted for loading railway cars with heavy arti Cles such as ba-les of cotton, and for similar purposes. ln beginning the work the delivery end of the elevating apron trame may bc. lowered and as work progressed said det6 livery en d is elevated in order to deliver the articles to be loaded, tier upon tier, the apron 47 being supported upon'the last completed tier while making delivery for the next tier to be stacked. v S0 The bales. or boxes, and the like are loaded onto the elevating apron at its lower end and are carried by it up onto the roll50 and thence by itlover the delivery apron, 47.

a ln some cases it may be found desirable 85 to provide upslanding transverse lugs` on the elevating apron. For this purpose there are at certain intervals the bearing members 55. 55. fastened to the ends of the slats 26,

and rods as 56 have end bearings in these eenv "517. On the upward movement of the apron these lugs will stand in vertical position to hold the load on said apron but as they pass .95 around the upperendV of the apron 'frame their lower ends will Contact with the cams 5S, 5S. carried by the upper ends of the' side members 5 and their outer ends will be thrown inwardly and held in suchposition until they pass within thehood 27.
