7b f//Z/ 'wl/fom, it 'Ht/ty concern:

Be it known that I, DANIEL O'r'ro, a citizen of the United States, residing at Danvers, in the county of McLean and State of Illinois, have invented new and useful Improvements in a Combined Grain Elevator and Dump, of which the following is a specification.

My invention relates to improvements in what may be termed combined grain loading or elevating and dumping devices. .It has for its object to provide for the convenient or mechanical tilting of the loaded wagon, as in dumping its load or contents, and to readily elevate or transfer such contents to a car or bin in an expeditious and effective manner.

Said invention consists of certain structural features, substantially as hereinafter more fully disclosed, and particularly pointed out by the claims.

In the accompanying' drawings, illustrating the preferred embodiment of my invention, Figure l is a plan view thereof. Fig'. 2 is a vertical longitudinal section therethrough. Fig. 3 is an enlarged detailed View in side elevation, showing more especially the motor or tumbling-rod-actuated shaft, the wagonplatform-tilting gear, and shaft-actuating mechanism, including the clutch-shipping lever for reversing' the direction of turning' of the clutch-carrying shaft and the endless belt carrying' the lug' for actuating said clutchshipping lever. Fig'. l is an inverse view of the clutclrshiliiping' lever disassociated from the other parts recited in Fig. 3. Fig'. 5 is a transverse section produced through Fig'. 3 intermediately of the intergeared connection and the gear and belt connection between the tumbler-rodactuated shaft and the countershaft used in connection therewith. Fig. 6 is a corresponding section taken through the wagon tilting or dumping platform and main platform or bridge adjacent to the actuating'- shaft and the chains or cables connected to said shaft for said tilting' platform Fig. 7

is a like section produced on a line passing through the main platform adjacently to the chock7 or stop for the hind wheels of the vehicle or wagon, as when Hin tilted position thereon. Fig. 8 is a broken vertical longitudinal section taken through the elevator, including two sections or members. Fig. 9 is a cross-section thereof produced near the derricl, or rather the swinging upright frame thereof and the elevator-suspending sti rrup or yoke, as viewed from the receiving side thereof. Fig. 10 is an enlarged de-A l tached view showing' more particularly the chock or stop and its spring' connection with the wagon or vehicle platform tilting lever i mechanism. Fig'. 1l is a view showing' the clutch or coupling member receiving plate applied to the shiiiping-lever with its sections disassembled. Fig. 12 is a broken-away detailed view showing' more particularly the lugs of the combined guards and stops secured to the grain-r ieiving trough-like receptacle for limiting' the downward and outward movement of the hinged memberof said receptacle.

In the carrying out of my invention I suitably construct a main platform or support l, preferably of longitudinal edgewise-arranged timbers 1 with slanting' ends and of transverse boards 1l nailed or otherwise secured down upon said timbers throughout, thus providing for the ready driving' on and off the same of a loaded team or wagon, and which platform has preferably secured thereto in any suitable way a draft-bar lc for the convenient removal thereof from place to place as it may be needed for use. Suitably braced upright frames or standards 2 are secured laterally to the platform l at opposite points, near one end thereof, with the vertical member or timber of each such upright frame having its diagonal or inclined member or brace 2 secured near its upper end upon the correspondinglychamfered end of said vertical member or timber and extending' beyond and suitably overhanging the latter for a purpose presently made apparent.

Suitably secured to the lower side of opposite lateral bars or timbers 3 are preferably two spacedapart transverse bars or beams 3a, principally constituting what may be termed the wagon tilting or dumping platform, such spacing apart of said bars being adapted to aid, as readily appreciated, the choclzing of the wheels of the vehicle or wagon at its elevated end, as presently more Afully made apparent. The lateral bars 3 of said platform are so disposed from their pivoting or bearing ends, as next described, as to enable the transverse or cross bars 3 when said wagon-tilting' platform is in its initial or horizontal position to rest upon the upper edges of the timbers l between certain of the boards ll, suitably spaced apart for that purpose, and thus constitute a part of the upper surface of the main platform for the loaded vehicle or wagon to travel upon as the latter is brought into position for dumping or tilting. Said lateral bars 3 have their pivoting or bear- IIO ing ends preferably longitudinally slotted, as at 3b, the slots thereof receiving lateral pivots 3C, projecting from opposite uprights or studs 3d, secured laterally to the platform or support l, which pivoting' or bearing ends or points are rendered adjustable, preferably by means of pins or keys 3e, inserted through any two coincident apertures of two registering` series thereof, 3f, produced in each of said bars upon opposite sides of its slot. The insertion of said pins or keys through openings or apertures nearer to or farther from either end of each slot of each bar of course permits said bars to be suitably moved to effect the positioning of the tilting platform according to the length of the wagon or vehicle.

Pairs of opposite linked-together levers 4 are arranged in connection with the lateral bars of the tilting' platform, the pivotal connection therebetween being' efected about centrally of their connecting-links, and to the rear end of said levers, as also to said lateral bars, near the corresponding ends is suitably lconnected a chock or bar for obstructing or preventing' the involuntary movement of the wagon or vehicle rear wheels when the wagon is in its tilted or dumping position. The connection between said chock and the levers 4 is effected by preferably right-angled hangers or brackets 5a, fixed to said chock at its upper rear edges and pivoted to said levers, while a bail-like or bent rod 51, has pivotal connection with the upper forward edge of said chock, the upturned or right-angled end portions of said rod being fixed to said lateral bars upon their lower surfaces to provide for the holding' of said chock at its forward edge flush with the upper surface of the main platform l and to permit said chock to be inclined upward and rearward by said levers as said lateral bars comprised within the tilting platform are actuated or raised at their forward ends, together with the like movement of said tilting platform. A preferably coiled or helical spring 6 is interposed between the levers 4 and the bail-like connection l to provide for automatically depressing' or returning the chock or bar 5 to its initial or horizontal position when the tilting platform is returnedor lowered to the corresponding position to effect the unchocking of the vehicle rear wheels at that time.

A shaft 7 is arranged down between upper surface-boards of the platform and journaled in any suitable way near the base of each upright frame or standard 2, upon one end of which shaft is secured a gear wheel or pinion 7 1, again later noted. To said shaft are connected and upon it are designed to be wound two chains or cables 8, engaging' pulleys 9, hung in the overhanging upper end portions of the frames or standards 2, said cables or chains then being engaged with pulleys l0,

hung upon and movable with lthe levers 4 in addition to having their hangers 10a, which are pivoted upon said levers, also pivotally connected to the lateral bars 3 of the tilting platform. Said chains or cables are looped back after having been engaged with pulleys l0 and fastened to the upper ends of the upright frames or standards 2, as shown, thus providing for suspending in position the tilting or dumping' platform after having' been elevated. Said chains or cables of course serve by the aid of their winding and unwinding shaft 7 to primarily effect the raising and lowering of the tilting' or dumping platform, as presently more fully disclosed.

A shaft ll is suitably journaled in position in one of the upright frames or standards 2 and an uprig'ht or standard 2b, adjunctive thereof, as is also a counter-shaft l2, which shafts are adapted for conjoint and simultaneous action, as they are driven alternately in the same and reverse directions to accordingly affect the chain winding and unwinding shaft 7. To these ends the shafts l1 and l2 are provided with an intergeared relatively large loose pinion or toothed wheel l1u and a small pinion l2, respectively, also sprocketpinions ll 12b, respectively, the upper being loose, belted together by a link belt 13, the counter-shaft l2 having worm or screw 12C meshing or geared with the gear-wheel 7 L of the chain-actuating shaft 7. A suitable tig'htener or contrivance 14 for the effective action or engagement of the belt 13 with the sprocketpinions llb 12b is applied to a vertical piece of one of the upright frames or standards 2. Said contrivance or tightener consists, preferably, of a right-angled member or casting 14, with one arm thereof adapted to be presented to and infieX said belt intermediately of the sprocket-pinions ll" 12b to put the requisite stress upon said belt for an obvious purpose. The other arm of said bracket has a vertical slot i4b extending therethrough and receiving a plate or bar 14, fixed laterally to a member of the uprig'ht frame at that side, and working' in said arm is a set or binding screw 14d, adapted to be engaged with said plate or bar to provide for the adjustment of the tightener and holding it against the belt 13, as in properly stressing' the latter.

The shaft l1, which is designed to be suitably connected to means for driving it, is provided with a sliding coupling clutch member 12, having the usual key or spline and slot connection with said shaft and adapted to be alternately shipped into engag'ement with facing half-clutch members l2e 120e, formed with the gear-wheel ll and sprocket-pinion 1lb, respectively, carried by said shaft and partaking of its movement and suitably delivering said movement, as above noted. An endless link belt 1l*15h encompasses two sprocketpinions llb, one secured upon the shaft 7 at one end and the other pinion suitably jour- IOO eoaaoe gaged upon one side of its pivot at the required interval in the operation of the aforesaid parts, as presently explained, by the lateral lug12CC of the belt 11m. Said lever is adapted to eli'ectconnection upon the other side of its pivot with and actuate the clutch or coupling member 12d, let into acorrespondingly-slotted preferably bisected plate 19], with the meeting' ends of its sections produced each with a half of the clutch-receiving slot thus formed, said plate or plate-sections being suitably secured to said lever, preferably as shown.

Adapted to be suitably disposed or adjusted with relation to the platform 1 is means for receiving and elevating the grain or contents of the loaded vehicle or wagon driven upon said platform, the same comprising an elevator 16, pivotally supported at its lower end within the bottom or base-frame 17L of a hind of truck or skid 17, and of a supplemental elevator 16, pivoted or connected to and adapted to deliver into the elevator proper, 16. The supplemental member 16Lcomprises a preferably rectangular trough-like receptacle adapted, as indicated, to be positioned upon the platform 1 near the rear end of the latter, and has its endless belt of carrying devices or carriers 16 suitably arranged therein for the effective conduct and delivery of its contents to the corresponding endless belt of carrying devices or carrier 16 of the elevator proper. Said endless belts of carriers or elevators 16b 16 are interacting or connected for continuous and simultaneous operation for obvious reasons. The power for effecting the operation of said endless belts of carriers of said elevators may be suitably applied thereto, as at 16a, and the connection therebetween and the motoror horsepower may be accomplished in well-known way, as by gearing, pulleys and belts, or otherwise. Said trougli-like receptacle has upon its receiving side at the upper edge a pivoted or hinged section or member 16C, adapted to be so disposed by suitably pressing or acting1 thereon with the hand or otherwise as to assume an upward and outward inclination, it being restricted in its movement, as presently seen. Combined stops and guards 16d consist, preferably, of metal plates suitably improvised or bent to permit their being secured, preferably, to the inner surface of the troughlike receptacle laterally of the opening occupied by the member or section 16c when moved into reverse position to that above ascribed to it, said plates extending edgewise through said opening and beyond said trough,

their lower edges at those points terminating in in ward-extending lugs or stops proper, 161, for restricting the downward and outward movement of said hinged section or member 16C. It will be observed that` as noted, said plates serve to guard against the lateral escape of the grain or contents of the vehicle as the same is being dumped or passes therefrom and whatever may fall upon said member or section. The elevator proper, 16, is suitably suspended and adapted to be moved vertically within a pivoted frame or yoke 17h of the truck 17 when in effective position, said elevator having pivotally connected thereto a bail 17C, to which is connected a line or cable 17, passing over a pulley 1T", hung from the upper end of said frame. Said line or cable is next passed and connected to and suitably wound upon the drum or cylinder of a windlass 17", whose shaft is journaled laterally upon the part 16. By suitably actuating' said windlass the elevator of course may be raised and lowered as desired, as when arranged for use or when it may be desired to fold or collapse the same for convenience in moving' the machine from place to place. As the frame or yoke 17, as before stated, is pivoted, it may be simultaneously collapsed or folded with the elevator, while the pivoted troughlike receptacle or member 16kl may be folded to back upon said elevator and these several parts bodily be piled or placed upon the main platform, with the tilting platform lowered thereinto, thus providing for the very compact folding' and disposing of the same, as desirable in their transportation.

lt will be noted that the loaded vehicle having been driven from the left upon the platform 1 and the team of course thereafter unhitched and removed the requisite movement is transmitted to the shaft 1l from the source of driving-power, putting in operation the gear and. shaft actuating` mechanism before described, the shipper or lever, however, rendering at this time effective the belted-together sprocket-pinions 11 12, consequently raising or inclining the tilting platform upon which the forward wheels of said vehicle are standing', accordingly disposing or inclining the vehicle. Y This will, it is obvious, result in so inclining or tilting' the vehicle or wagon tailgate endward that upon suitably adjusting said tail-gate the grain or contents of the vehicle will gradually liow therefrom and enter or be dumped inte the trough-like receptacle discharging into the elevator proper, above noted, thus providing for the delivery of said grain or contents of the vehicle into a car, bin, or other elevated point. As during the action of the aforesaid gear, Sac., actuating' mechanism the belt 12u, carrying the lateral lug 12C", is of course in motion, said lug will, by about the time the tilting platform reaches its maximum inclination, effect engagement with the clutch-shipping lever from the right IOO and unship the clutch from the sprocket-wheel 1lb at that side, and thus provide for stopping said action of parts when the unloading operation will have been effected. At thisjuncture the transit of the clutch or coupling member upon the shaft 11, under the action of said shipping-lever, across to and its eng'agement with the sprocket-pinion 11a will again set in action the aforesaid gear-actuating mechanism, this time in an opposite or reverse direction, consequently providing' for the lowering of said tilting platform with its superincumbent weight-that of the unloaded vehicle. As duringl this reversed action of parts the belt 12im with its lug 12CC will accordingly travel in the opposite or reverse direction, and about the time the tilting platform has reached its lower point said lug will have been oppositely brought into engagement with said shipping-lever, the clutch or coupling' member will then be disengaged from said pinion 11, and thus stop the action of said gear-actuating mechanism for the repetition of the aforesaid operation.

It will be noted that the tilting platform bearing the vehicle is more slowly raised through the belt and sprocket gearing than it is lowered through the spur-gearing, as above disclosed, for obvious reasons.

Latitude is allowed as to details herein, as they may be changed as circumstances suggest without departing from the spirit of my invention.
