norsrme AND LOADING DEVICE Application filed September aziaa'e. serial No. 395,717.

My invention relates to improvements in hoisting and loading devices, and the object of my improvements is to supply a simple, inexpensive device of this class particularly adapted for loading railway gondolas or other cars, or any other receptacles as desired conveniently, and operable by manual or other power, while being compact to employ a minimum space therefor.

This object I have successfully accomplished and examplified by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Fig. -1 is a front elevation of my improved device, showing the shoot bucket in its lowered receiving position, and Fig. 2 is a side elevation, with a part of the frame structure broken away, showing the bucket in its elevated and tilted 29 delivery position. Fig. 3 is a detail side elevation of the bucket and its bail in a receivin position.

y invention is not restricted to the pre V cise construction and arrangement of parts herein shown and described, nor to the various details thereof, as the same may be modified or rearranged in various particulars without departing from the spirit and scope of my invention, one practical embodiment of which has been herein illustrated and described without attempting to show all :of the various forms and modifications in which my invention might be embodied.

My device includes a supporting frame Which may be rigidly fixed upon either a permanent or a movable base as desired, and comprises the spaced inwardly channeled vertical beams 1 connected at the upper ends by a pair of spaced cross-bars 2. Between these bars a grooved sheave 13 may be rotatably mounted, and said bars may project at one end and another sheave 14 rotatably mounted between these extensions.

In the interspace of the standards 1 is positioned an open top elongated shoot bucket whose forward closed end 3 is of greater height than the elongated delivery part 4.

the latter being open terminally. This m bucket is also preferably shaped with its receiving end at the bottom flat to support it as in Fig. 3 upon the supporting base hori zontally, the elongated shoot part' e-being directed slopingly upwardly at a desiredangle; A cross-bar 5 is fastened across the bottom of the bucket with projecting pintles 6, and located so that the bucket isunbalanced towardits receiving end'3/ The numeral-8' denotes a bail having depending members? whose terminations are apertured to seat'the pintles 6 of the crossbar 5 tiltably. These members span the inter space of the standards 1 and are slidabl mounted in the inner channels of the stand ards to ride therein whenthe bucket is hoisted or lowered to prevent lateral rocking of the bucket. To the middle of the bail 8 a; double-ended eye-bar or link 9 is secured by a bolt or pintle 10, and its upper eye receives a loop on the flexible cable 12 depending from and reeved upon the sheaves 13 and 14. The cable thence passes downwardly to and its end secured upon the winding-drum of a winch 16 rotatably mounted on a fixed bracket on onestandard 1 at 15 on a shaft 17. The shaft has a terminal handled crank 18 for manual operation of the winch, a ratchetwheel 19 on the shaft releasably engaged by a gravity pawl 20, preventing release of the cable and the bucket when the latter is raised to any position for tilting. It will '80 be understood that instead of a winch, any other means may be used for actuating'said cable 12, such as a motor, whether electric or using compressed air or otherwise.

Any desired means may also be employed 86 for the purpose of tilting the bucket to a delivery position, such as a chain 21 connected to its spout or delivery end 4 (shown in Fig. 2), as the bucket being unbalanced toward its receiving end is hoisted in that position, 0 and when unloaded and the pawl 20 tripped to release it, the bucket tilts back under the influence of the greater weight of its receiving end tb its normal position shown in Fig. 3.

The numeral 11 denotes a pair of bent bars fastened to the opposite parts of the bail cross member 8 having their depending and forwardly hooked ends over the bucket. When the bucket as shown in Fig. 2 is in its tilted position to deliver its contents, the

, tiltedto discharge its contents, and also to v hooked terminations of the stops 11 engage the forward inner Wall of the bucket to limit its farther tilting.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

A device of the character described, comprising a supporting structure with spaced vertical guide standards, a shoot bucket, hoisting means for raising and lowering said bucket including a bail "connected there to pivotally at one side of the buckets center of gravity to permit it to nornially tilt toward its receiving end, said means being slidable upon said standards top'revent later'-' al rocking of the'bucket, and spaced hooked p n g fi s, upon, thejba l a p d t engagethe bucket rear wall Wh en the latter is li rnit the tilting position of the bucket its normal receiving positionf w 'In'testimo'ny vvhereofl aifix my signature.
