LOADING AND UNLOADING MACHINE.

Application vfiled July 19,

T 0 all whom it may concern:

especially adapted for automatically and mechanically transporting or transferring hides and skins, and for charging and discharging receptacles with such hides and skins, such as tanning machines, dye vats, drying lofts, etc.

The invention is designed primarily for the purpose of providing a new step in the j" through the machine, carrier. and hide sup-v handling of hides and skinsduring the process of tanning, and especially for the.

purpose of eliminating hand. labor, to a great extent, in which the laborers are ex posed to a tiresome and unsanitary work, thus reducingimmensely the cost of labor and production of tanned materials.

The invention mechanically considered consists essentially of a main portable truck, for conveying or transporting skins and hides from place to place for various treatments during the process of tanning, and also contemplates an elevator structure on the truck upon which'an auxiliary carriage or carrier is movable, and an extensible track way by which the carrier may be projected to proper position where a hide-sup porting member carried by the carrier may be either loaded or unloaded from thecarrier as the case may be, andthe invention further consists in certain novel combina tions and arrangements of parts as will be hereinafter more fully described Q and claimed. v.

' In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention, constr'ucted and arranged according to the best mode I have so far devised for the practical application of the principles of my invention, and while I shall hereinafter refer to the device in connectionwith the handling of hides and skins, it will readily be understood that other articles or objects may be handled equally well by the machine.

In the preferred form of the invention as illustrated in the drawin s, the portabletruc'kis made up of a metallic horizontalbase frame 1 fromwhich rise the two. pairs of up-' right corner posts 2 and 3. The upper ends of these posts 2 and 3 are connectedin pairs bv longitudinally extending side arms '4! and members of the frame where they are supported nbearings 8, and at theupper end of the frame additional bearings or bracln ets 9 are provided so that these screw bars tudinal sides of the truck frame, being supported in journal bearings 19, and the driving shaft is coupled to the countershafts through the bevel gears 20 and 21, the gear couples being located at the ends of the driving shaft vasloest seen in Figure 6, Each countershaft is provided with a pair of worm screws, as 22 23, and these respective worm screws engage the worm wheels 291, four in number and one each fixed on a screw bar or upright threaded post 7, so that when j the driving shaft is actuated thetwo coun ter sliafts impart rotary motion to the screw bars through the medium ofthe bevel gear couples and the screw couples as described. 7

Through the rotation of these four screw bars the elevator is operated, and this elevator comprises a frame, open at its front,

7 horizontally disposed, and preferably'of fiat metallic side bars25, having at the four corners of the rectangular shaped frame the fixed nuts26 each threadedfor a screw bar 7, and each firmly bolted or riveted to the elevator frame. Thus it will readily be seen that when these four screw bars are revolved in unison, the elevator will be lifted or low- ,ered, depending upon the direction of rotation of the screw bars.

The two bars 25 of the elevator frame form rails or tracks, positioned, always, in a horizontal plane, and anupwardly inclined, fixed rail 26' forms a continuation or extension ofeach of these rails, these inclined rails being riveted or bolted to the horizontal side rails of the elevator, and, of course'the "fixedrails or inclined ra ls move bodily with the Y horizontal rails as the'elevator is operated,

The rails may be elongatedQand to accomplish this purpose I provide an extension rail 27'for each of the inclined rails 26', the extension rails being adapted to telescope or slide within grooved guideways located at the inner sides of the inclined rails 26, and each provided with a horn or-bumper 28 at its extreme end. The slide rails oriextension rails are projected from the stationary rails of the elevator by means of a' pair of hains 29, one at-each side of the elevator,

. end arms 4-6 and sharp pins or studs l7,

platform 35 which joins the side bars 25 of the elevator, at the rear of the machine. The drums may be revolved from the driving shaft 36 through sprocket gearing indicated at 37 in Figure 11 from aconventi'onal clutch mechanism shown in said figure, to wind the chains on the drums, and the winding of the" chains of course draws the carriage; as to the right, in Figure 2. The carriage is provided with four wheels arranged in pairs 38,38, on axle 39, and 4:0, 10 on axle 11." Thus when the slide rail is projected, or rather when the carriage is made to project the rail, the winding of the chain on the drumlfirst draws the carriage along the rails 25, 26 until the front wheels 40 encounter the horn shaped bumpers 28 and ride up onv them assh'own best in Figure 2, then the continued pull of the chains causes the extensible frame for rails 27 to slide upwardly and outwardly, vith the wheelstl supported on the bumpers and the wheels 38 rolling over theinclincd rail 26 until'the extensible rails and 'carriagereach the projected positi'on iirFig ure2. U1 The'carriage 31 is joined at the front the cross arms 42 and at the rear by the cross brace 43, and it will be understood that the axle 39 at the rear may extend across from side bar to side l ar of the frame, butthe axles for wheels 410 are stuh' axles' ll in the 'I'CSpGC't UQ, side bars of. thefriaiiie, so; that a hide or skin 44: may be carried between these, side bars of the carriage frame. The hides or skins are supported on a suspending mem her which I shall terma carrier, which com prises two end brid 45, (t5 formeduvith V A and, between these two hrioges arefsup o'r ed plurality of suspension bars or rods 48 each of wl'iich is so'cketed to fit over the pin's on the bridges, and tho hides .o V pended 'lrom these rods orbais. Thel res 45 of the carrier are ri 'dly supported on the can 31, and the suspension bar as illusii ted in l igure' 20f thedrawi are designed to be suspended inithe rota barrel 19 forming p rt of atanniiig in chi One head of the ha i i of the projected machine, and both heads of" tlioflharrel are provuiled with supporting means so that the bars 18 may be suspended longitudinally'of the barrel at the inner pe: riphery thereof, andwhen the barrel i s'rotatedthe hides or skins on the bars l8 are carried bodily around with the barrel. The: machine of the invention isso constructed" that it "will manipulate the carrier susslrins 'are sus-l el isopen for admission" by V pend the hide supporting bars in the rotary barrel. .Thefirst part of the operation has been accomplished in full lines in Figure 2,

and the forward ends of thebars 48 are supported on a ring 50 at the distal endof the arrel, while the second part of the movement is indicated in'dotted'lines in Figure 2, where the-bars are supported between the ring 50 and a similar ring 51 at the proximate end of the barrel. 1

..Th proximate end of the carrier is'lifted from position in full linesFigure 2 by' a' pair ofllifting'jackssupported on the ele-' vator, which acksv lift the carriage, or rather one end of thecarriage and swing it upwardlyon the Wheels 40 as pivot points.

These lifting jacks are operated in unison from the-driving shaft 36' at the rear of the "ions 60 on the vertical-screw bars 61. supported in bearings 62 on1a leg 63 ofthe elevator;v On'each'screwbar is athreaded nut '64 formed with: an' arm 65 which supend each lever is provided with a hooked or curved-seat 68 adapted to engage up under the two ends of the axle 39 of the carriage. Now when the jacks are operated as described it will readily be seen that the carriage will be swung on the front wheels as a pivot, the forward end being lowered and the rear end lifted so that the proximate ends of the hide bearing arms are lifted and moved endwise into place as before indicated. The hide bearing arms are of proper length to permit endwise shifting when they are being lifted above the bars 50 51, and are of suitable length to rest on said bars. In order to withdraw the projected part of the machine from the barrel, the jacks may be lowered, or the elevator may be bodily lowered, the carriage permitted to run down its inclined tracks and the extension or slide frame withdrawn or retracted, as by a pull chain, not shown.

In Figure 4 the machine is manipulating the hides and their carriers so that the hides are suspended in a loft, between the two horizontal supports 69, 70, the operation, however, being practically the same as when the hides are placed in th barrel or receptacle of the tanning machine for treatment.

In Figure 9 a sectional form of the hide supporting bar or rod is illustrated, this form also being shown in Figure 5; Here the lower section 71 has sockets 72 to fit over the pins or'studs 47 on the brid e and the intermediate section .73 has doub e end spikes 7 4 projecting from its top and bottom to engage sockets 7 5 in the lower section and similar sockets, 7 6 in the uppersec'tion. The

hides or skins are suspended from the barsas indicated in Figure 5, being retained between the upper section' and intermediate section and the lower section and intermediate section respectively.

The carrier which supports the brindl of hides. or skins may be of various constructions, andthe useofthe machine may be varied greatly,b,ut thegoperation remains the same, and :while I have described the n'iachine in connection with the treatment of hides, it will readily be understood that Changes may also be 'made in thecon-..

struction of the machine, within the scope: I

of my claims-without departingfrom the spirit of my invention, and all such changes are contemplated. e

In operating the machine in the process of treating hides and skins, withthe loaded carrier supported on the carriage, the apparatus is brought-toposition of Figure 1, ready toisuspend the carrier and its hides in the tanning machinebarrel 49. The ele- V j V vator is lifte'd to the position indicated in I ports a lifting lever-=66 that r isslida ble 1n J bearings 67 on the elevator, and at its upper.

by the movement of both the elevator andthe projecting apparatus, that the upper ends of the hide supporting bars are located in their suspension devices in the barrel, and then the lower end of the carriage is tilted upwardly by means of the elevating acks so that the proximate ends of these hide supporting bars are emplaced, as shown in dotted lines Figure 2. After the carrier has been properly deposited, the jacks are lowered, the carriage will roll down its incline, and then the carriage and extensible frame are retracted.

No claim is made herein to the particular form of carrieror hide supportingbars, nor

to the special manner of loading tanning mato desired position, as for instance, a flat suspension or a folded one, or partly suspended, or hose shape, a single hide or a whole pack, with the hides and skins overlapped at their bases, or enveloping such hides and skins in such a bag form as may' be designed by the operator. -What I claim is l.
