To all whom it may concern.'

. Be it known that LCHARLES E. YARIAN, a citizen of the United States, residing at Galion, in the county of Grawford and State of Ohio, have invented certain new. and useful Improvements in Traversing Hoists; and I do hereby declare the following to be a. full, clear, and exactdescription of the invention, such as will enable others skilled in the art to Which it appertains` tomake and use thesame.` a a 4 This invention relates to traversing hoists and more particularly to `that class of hoists designed to be used in handling coal, sand. gravel, crushed rock and materials of similar description. l

lt has been' found in practice that dealers in the above mentioned materials, who receive these products in carloadlots, suffer serious inconvenience in unloading and stor-` ingthe same, owing to railroad regulations relative to the location of the storage bins of the dealer with respect to the companys tracks. As switches and sidings are only obtainable at considerable cost, and as'this cost is in proportion to the length of the siding, asidingr of minimum length is greatly to bedesired. 1 e y With these facts inmind, it is the object of this inventionto provide means for `unloading material suchl as coal, crushed rock, sand, gravel, etc., from the car in which it is delivered to the dealer, conveying said ma` terial to its proper storage bin, said means being adapted to receivethe various mate` rials at the same point on the same siding, and transfer" them to their respective bins, which may be placed at any convenient location;

With this and other objects in view that may more fully hereinafter appear,the invention contemplates the provision of a plurality of storage `bins which are preferably located in a line at right angles to the tracks of the siding, but through proper arrange ment of the parts" hereinafter described.wtl1e bins may be placed in any convenient location. The invention further comprises a traversing hoist provided with a novel cable clamping device by which the `conveyer` bucket and its contents may be raised to any desired height priorto its journeyto the bin, and retained, if desired, at" this height throughout its course, being automatically dropped-atits bin by a trip located above said bin 0n the overhead track.`

V Onev embodiment of my inventionis hereinafter fully described and illustrated in the accompanying drawings, and more particularly pointed out in the appended claims, it being fully understood that" such changes in size and proportion oflparts and in minor details of constructionemay be made as clearly fall Within the scope of the appended claims without departiiig fro-1n the spiritor sacrilicing any of` thegadvantages of theini'fention.` y y ln Vthe accompanying i drawings `Figure 1` is a side elevation of the over-` head track *with "the traveling carriage mounted therein, and the conveyer bucket suspended fromlsaidcarriage. e

Referring more l particularly "to the accompanying drawings l and the embodiment of my invention disclosed therein,`

4l() designates `an, overhead track `of `any suitable material supportedby any `preferred means, such as upright membersflll, and a plurality `of overhead hangers 42, said track being pOVdedfWitb aplurality of longitudinal grooves 43 on its upper face designed to receive the rollers or wheels of the traveling carriage, as wlllbe hereinafter described. i

The `overhead track is carried above the a mounted uponfthe undersideof the track bv means of "suitable" yokes or bearings 45,

whichareadaptedtoreceive a pintle 46 upon which thetrips arerotatably` mounted. Atthe points oir the track where is desired to mount said trips, the track is reeessed as at 47, said recess having a cylindrical duct 48 communicating with the upper face of the track.

The trips 44 are provided on their upper faces 49 with a resilient member 5l secured to said trips by screws 50, said screws being provided with eyes 50a designed to receive the. rods 52, said yrods extending upward through the ducts 48 and extending slightly above the upper face of the track,

.and having at their upper ends an eve 53 designed to receive a cable 54. The resilient members 5l are designed to engage the upper faces 55 of the recesses 47 to return the trips 44 to their outward position.

The traveling, carriage, designed to ride upon the overhead track 40, comprises a substantial frame 60 provided with a plurality of wheels or rollers 56 suitably journaled on pintles 57, a separate and distinct pintle being provided for each roller, as clearly seen in Fig. 5. The purpose of this mounting of the wheels is to provide for the passage of the overhead hangers 42, and the cable 54 between the rollers kpositioned on opposite sides of the frame, when the carriage is mounted on the track as shown in Fig. 5. .The hangers 42 may be provided with suitable apertures 58 to receive the cable54.

Suspended from the carriage frame 60 by vertical members 59 is a frame 61 carrying a plurality of pulleys 62 and 63, said pulleys being rotatably mounted on suitable pintles 64 carried by said frame. e

Suspended vfrom the frame 61 by a plurality ofcleats of equal length 65, is a frame 66. The cleats 65 are pivotally mounted to the frames 61 and 66 by suitable pintles 68, thereby allowing the frame 66 longitudinal motion with respect to the frame 61, and at the same time retaining the frames in a po` sition parallel to each other.

Pivotally mounted on the frames 66 and 61 is a cable clamping device, best seen in Figs'Q and 3. The frame 61 terminates at one end in `enlarged portions 69 between which is rigidly positioned a gripping block 70, vsaid block being'provided with a plu rality of teeth or corrugations 71. Pivotally mounted between the opposite sides of the frame 66 upon pintles 72 is a pivotal jaw 74 having a corrugated facev74el to coperate lwith the corrugated face 71 of the gripping block 70, to clamp a cable passed between said faces, as hereinafter described. This construction -is vclearly shown in Fig. 3, where is disclosed a plurality of 1egs'73 carried by the jaw 74 and yby which saidj aw is attached to the frame 66. AsV shown in Fig. 3, the jaw extends upward between the opposite sides' of the frame 61 and is rotatably connected tol iframe 61 by a pintle 75, said pintle carrying a suitable pulley 76.

The pulley 63 of the frame 61 is provided on its outer periphery .with a plurality of teeth 77, designed to engage a bar 77 carried by the legs 73 of the jaw 74, when said jaw is rotated on pintle 75 by a longitudinal movement of the frame 66 as will be hereinafter fully described.

Suspended from the traveling carriage by a suitable cable 78 fastened to a bar 79, carried between the opposite sides of the frame 61, is a frame 80 from which is suspended a suitable conveyer bucket 87. The frame is shown provided with a plurality of pulleys 81 and 81a suitably journaled on pintles 82 carried by said frame. The cable 78 is led downward from the bar 79 through the pulley 81 upward and around pulley 62, thence downward and through pulley S1". thence upward and. around toothed pulley 637 thence over the pulley 76 of the jaw 7i between the legs 73 thereof and the faces 74a and 71 of the jaw and the gripping block, respectively, and thence by means of a swiveled pulley 83 to the drum of a hoist.

The operation of the device is as follows:

The bucket having been lowered and filled in the usual manner is then raised by applying power to the cable 7 8 to any desired height, and :when such height has been attained, power is applied to the cable 84, thereby communicating longitudinal movement to the frame 66 in the direction in which the force is applied, causing the pivoted jaw 74 to rotate on its pintle and comel into clamping engagement with the cable 7 3 passing between the corrugated faces 7 4 and 71, at the same time bringing the bar 77" into mesh with the teeth of the pulley 63,

thereby effectively lorking the same. Power is then removed from theV cable 78 and through the force applied to the carriage by means of the cable 84, the traveling carriage proceeds along the overhead track.

The pivoted jaw 74 is provided with an extended portion which terminates in close proximity to` the underside of the overhead track, and is so positioned as to engage the trips 44 mounted thereon. It is evident from the foregoing description taken in connection |with the accompanying drawings that the trips are s0` mounted as to permit of the free passage of the carriage in one direction, but will offer obstruction to its passage in the opposite direction. Having this in mind, the carriage is pulled freely along the track until the desired storage bin is reached, above which is positioned a trip. The carriage is pulled past the trip, said trip being forced into its recess by the end of the jaw 74, and said trip being forced outward into its operative position by the resilient member 51. The carriage is then pulled back so as to bring the extended portion of the jaw into engagement with the vertical masones face of the trip, thereby causing the jaw to be opened., the cable to be released,and the bar 77a to be drawn from engagement with the teeth 77 of the pulley `(53, allowing the bucket to be lowered.

When the contents of the bucket have been discharged, the bucketisraised to any desired height and a slight pull given to the cable 84e to clamp the cable 7 8 between :the jaw: 74 and the gripping block 70, and tobi-mg" the bar 77au into engagement with the teeth of the pulley 63, thus effectively locking thc bucket at the desired height. The cable 54 is then pulled to draw the trips into their respective recesses, thereby allowing the carriage free lpassage along the track. "When the carriage has passed the last trip before the one located above the loading pit, the cable 54 is released, allowing the trips to resume their operative position. The jaw 74 coming into contact with the trip, thus placed in operative position, is opened and the cable and pulley released, as before described, and the bucket lowered for reloading.

Having thus fully described my invention what I claim is y 1. The combination with a track, ot' a carriage to ride thereon, a bucket suspended from the carriage, means to raise and lower the bucket with respect to the carriage, means carried by the carriage to retain the bucket at any desired height, and coperative means between the carriage and the track to release the bucket at a plurality of predetermined points.
