ELEVATING AND TRANSFERRING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 557,345, dated March 31, 1896. Application filed August 15, 1895. Serial No. 559,322. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN F. SHUART, of Oberlin, in the county of Lorain and State of Ohio, have invented certain new and usef ul Improvements in Elevating and Transferring Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in elevating and transferring apparatus more especially designed for receiving a deposit or deposits of sand or other material at or near the ground and lifting and transferring the load to a wagon, car, or other vehicle at hand to receive it.

lVith this object in view my invention consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan, partly broken away and in section, of apparatus embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation, in central vertical section, showing the dumping-platform and dischargingchute of the apparatus in a dumping position in solid lines, and showing in dotted lines the dumping-platform and its supporting tilting frame in an intermediate position.

The illustrated apparatus comprises a rectangular stationary horizontallyarranged frame A, that is preferably provided with wheels A to render it portable. Frame A is designed to rest upon the ground or upon a track. (Not shown.) A vertically tilting frame B is pivoted at one end, as at b, to and at or near one end of frame A. Frame B, in its lower or normal position, rests upon members A of frame A. A vertically-tilting platform C is suitably supported from the outer portion of tilting frame B and is shown pivotally connected in any approved manner, at or near its inner end, to the central portion of frame B. The pivotal connection between platform 0 and the supporting-frame B consists, preferably, of a shaft or rod B arranged transversely of and suitablysecured to frame B and extending through any suitable number of staples or straps O arranged at suitable intervals transversely of and suitably secured to platform 0. A cable D is suitably attached to the outer end of frame B, and said tilting frame is tilted upwardly, as shown in solid lines, Fig. 3, by actuating cable D in the one direction, and is lowered from its upwardly-tilted position by paying out the cable in the opposite direction.

Cable D, in the case illustrated, is attached at one end, as at D, to the block of tackle suitably secured to the central portion of a cross bar or beam E, that extends between and is suitably secured to two upright posts or standards E E arranged a suitable distance apart and suitably secured to frame A. From point D cable D leads to and over a sheave D of a tackle attached to the outer end of tilting frame B, thence to and over a sheave D of the tackle borne by cross-bar E, thence to and over another sheave D of the tackle attached to frame B, thence to and over another sheave D of the tackle attached to member E, thence horizontally along the side of said member E to and over a sheave D borne by and at or near one end of said member E, whence it leads to the place at which it is hitched or engages the animal or means employed in actuating the cable.

The sand or material to be elevated and transferred to a wagon or vehicle is deposited upon platform O when the latter is in its normal or lowered position, and the load is dumped from said platform, whenthe latter is elevated, into a vertically-tilting chute G,

,located at a suitable elevation and pivoted at any suitable point between its central portion and its rear end, as at g, to and between standards or posts E E, and is adapted to discharge into the wagon or vehicle at hand to receive the load. Chute G should be so arranged that the greater portion of its weight shall be forward of its axis, so that the chute when free shall automatically tilt into its outwardly and downwardly inclining or operative position (shown in solid lines, Fig. 3) against a stop H provided for limiting the movement of the chute beyond the desired point in actuating the chute from an inoperative to its operative position. Stop H consists, preferably, of a cross-bar rigid with posts or standards E E. One or more cables I establish operative connection between said chute and tilting frame B. Two cables I I are secured to and at or near the outer end of the chute and at opposite sides, respectively, of the chute, thence lead upwardly to and over different sheaves I I, respectively, secured to the different posts or standards E E, respectively, and thence lead to frame B, to which they are secured at any suitable point between the central portion and hinged end of the frame. It will be observed, therefore, that when frame B is tilted upwardly chute G is tilted into an operative position, as required, to adapt it for discharging any thing received by it into a wagon, ear, or vehicle K placed under the discharging end of the chute.

The dum pin g-platform, to prevent any portion of its lead from dropping therefrom at the sides of the platform, is provided with two preferably metallic gates L provided at opposite sides, respectively, of the platform and hinged at the lower end in any approved manner, as at L, to the platform. The dumping-platform is adapted to tilt downwardly a limited distance, as shown in dotted lines,

Fig. 3, during the upward movement of frame B. Said downward tilt of the dumping-platform is shown limited by any suitable number of chains M, suitably attached at one end to the outer end of frame B and at their opposite end to the outer end of the dumping-platform, and the latter at its outer or rear end is provided with an upright guard 0 adapted to prevent any portion of the load from dropping off said end of the platform during the downward tilt of the latter. The capability of the dumping-platform to tilt downwardly, as hereinbefore indicated, enables the horse or animal employed in actuating said platform and its load to obtain an easy start before the entire load is brought to bear upon the animalthat is, the weight of the load, as the animal begins to pull upon the actuating-cable, is distributed between the animal and a bearing A with which frame A is provided, and the animal does not do all the work required of it until after said platform has tilted downwardly by gravity relative to frame B and has been raised above and disengaged from bearing A that consists, preferably, of a cross bar or beam arranged transversely of and rigid with frame A.

The backward or downward tilt of platform O relatively to the frame B is furthermore essential in handling many materials to prevent the material from being spilled out before the platform can be brought into position to connect with chute G. The dumping-platform in its normal position is therefore supported from frame B and from member A that is cut away at each end, as at A (see Figs. 1 and 3,) to accommodate the location of frame B in the latters lower or normal position. The arrangement of parts is such that in their normal position the side gates L of the dumping-platform overlap the side members of frame B, and preferably the side members of frame A also, and are open, as shown in Figs. 1 and 2, and hence when the dumping-platform is tilted downwardly relative to frame B said gates are automatically tilted upwardly or closed by the upwardly-actuated frame B, as shown in Fig. 3. The dumping platform at its forward or hinged end is pro vided with a gate or apron Q, that is hinged at its lower end, as at Q, to the platform in any approved manner. This end gate is closed in its normal position and is secured or locked in said position preferably by means of two latches R, pivoted at R to and at opposite sides, respectively, of the dumping-platform and projecting upwardly in the direction of, and preferably somewhat beyond, the discharging end of the platform. Each latch R a suitable distance from its upper extremity is shown provided with a shoulder 7', that in the operative position of the latch engages the forward or outer side of a pin or member Q projecting from the edge of gate Q, and thereby locks said gate in its closed position. Latches B, when the dumping-platform has been elevated into its dumping position, are actuated by han d or otherwise in the direction required to unlock or release gate Q and permit the latter to swing open by gravity downwardly against the bottom of chute G,as shown in solid lines, Fig. 3. The arrangement of parts is such that gate Q shall be adapted to bridge the space between the dumping-platform and chute G and overlap the bottom of the chute a suitable distance, and the side gates L of the dumping-platform preferably extend beyond the discharging end of said platform, as required to prevent a portion of the load from dropping from gate or apron Q, between the load-conducting chute and plat form.

Means for automatically actuating latches R in the direction required to unlock gate Q, is shown provided, and consists, preferably, of a rod S, arranged horizontally between posts or standards E at a suitable elevation and supported from the upper bifurcated ends of upright arms S, that are pivoted at their lower ends by horizontally-arranged pins S to said standards orposts. Pivotal pins S are screwthreaded at their outer or free ends, and handle-bearing nuts S are mounted upon said ends of the pins and are adapted to secure arms S in the desired adjustment. The arrangement of parts and trend of the forward or upper ends of the latches are such that red S,when the dumping-platform is elevated into a dumping position, shall. be engaged by the forward or upper end of latches R and there by render said latches inoperative, as required to unlock and permit gate or apron Q to swing open, and said actuation of the latches is effected earlier or later, according as red S is adjusted so as to sooner or later engage the latches.

Some earth and materials will run or move at a less declivity than other earth or other materials, and the object of the adjustability of the latch trip-rod is to enable the dump ing-platform to be given a greater or less declivity preparatory to the dumping operation, and thereby accommodate all grades of sand, earth, or other materials.

Latches R extend, preferably, downwardly through slots in the dumping-platform, and below said platform terminate, respectively, in a foot or laterally-projecting member R that is adapted to engage the under side of the platform and prevent the downward movement of the trip-rod-engaging end of the respective latch out of convenient reach during the return of the dumping-platform, after a dump, to its normal position.

To increase the portability of the apparatus, the upright posts or standards E are hinged or pivotally connected to frame A at their lower ends, as at e, and the braces T, that brace said standards or posts from the side members of frame A, engage mortises or recesses in said frame and standards and are removable to accommodate the folding of members E downwardly against frame A, and tie-rods t, that are instrumental in securing braces T in place and tie together frame A and the uprights E adjacent to the braces, are provided, respectively, with a turnbuckle t for tightening or loosening the same, as the case may require.

The sand, earth or material to be elevated and transferred to a car or vehicle at hand to receive it may be hauled or deposited upon the dumping-platform in any suitable manner, and said platform is preferably large enough to enable a team to travel over the same, and if the material deposited upon the platform is hauled thereon by a team the ca ble-engaging tackle attached to frame B is of course detached from said frame and moved with the cable out of the way of the platform loading operation.

My improved apparatus will be found especially valuable in expediting any excavating worksuch, for instance, as excavating work attending the erection of large buildings in cities, the construction of canals, and also in transferring or distributing material at docks, yards, &c.
