To all whom 'it may concem:

WELCI-I,'fl citizen'of the United States, re-

siding at Aurora, in the county of Kane and State of I inois, have invented certain new and usefuqlmpi-ovements in Folding Elesv a specificavators, of which the'following'i tion, reference being ing drawings, v

Mv'invention relates to machines for han- "plicable to .other uses, but has particularly .to do withmechanism forelevating or con- "veying materials,

such as. crushed. stone, etc in connect on with road-making, gradmg .and other analogous work.

v I 'The object of my invention is to provide 1' a new and improved construction by which the elevator may readily be folded for trans portation purposes or extended for use. I accomplish thisobjct as illustrated in the drawings and as hereinafter described.

v What I regard as new is set forth in the claims.

in which my improved connection with a port- In the drawings, elevator is shown H1 able stonecrusher,-Figure l is a side elevation showing the elevator extended ready for use; Fig. 2- is a side elevation showing the elevator folded; Fig.3 is a View on line 33 of Fig. 1 slfowing the elevator in elevati0n;. Fig. 4 is an enlarged detail, being a plan view of one of the horizontal arms which which a side elevation showing the arrangement of the Windlass by which the hoisting cable is carry the guide rollers 'or fulcrfa over -operated; Fig.6- is a side view showing the construction of the hinged joint of the elevator frame; Fig. 7 isa view at right angles to that shown in Fig. 6; Fig. 8 is a view illustrating one of the straps or links for the elevator frame;

Referring to the drawings,-9 indicates a of any suitable construction and is mounted on a carriage ',-compr1s1ng a frame 10 provided with wheels ll-12 so that it may readily be transported. 1314 indicate uprights, which are mounted on the frame 10 and are suitably had to the accompanyf I or sheaves 19-20 set ashort distance apart,

etc., and it is also ap-= shown in Figs. 1 and the hoisting cables operate; Fig. 5 is.

stone-crusher which may be 'andl 3, which are rigidly secured thereto, Be it known that I, SAMUEL FRANK'Z preferably by bolts 17, as shown in Fig. 4, from which it will be seen that said arms project ashort distance to the left of the uprights and a greater distance to the right 16 carry pulleys or sheaves l8, and at their longer ends they are provided with pulleys as best shown in Fig. .4. The several pulwill be hereinafter described.

' 21 indicates braces by which the longer ends of the horizontal arms 15-16 are braced from the uprights '13-l4, as best 22 indicates an endless conveyer, preferably of the bucket type, which is mounted upon a hinged frame, the construction of which is best shown in Figs. 1, 2 and 3. Said frame is composed of two. parallel members, preferably tubes, each composed of a lower member 23 and an upper member 24 whichare hinged together, as shown at .25 in Fig. 3., The hinge of said members is also shown in Figs. 6 and 7. As therein shown, a single pivot 26 serves as the hinge for both side members of the elevator frame.

27 indicates an intermediate brace for the upper members 24, and 28 a similar brace thereof. At their shorter ends the arms leys form fulcra for the hoisting ropes as' for the lower members. 23 of the elevator frame.

29 indicates a shaft which connects the lower ends of the members 23 ,and also carries sprocket-wheels 30 or a pulley around which the endless conveyer 22 passes. In-

.the shaft 31 and driven by a chain 38 from 1 which is mounted on a a sprocket-wheel 39 shaft 4Q journaled in suitable-bearings carried by the lower members 23 of the ele-' vator frame, as shown in Fig. 3. Said shaft is provided with a pulley 41 which is driven 55 anatieallyraised clear" 075 bv a belt 42 froma pulley 43 carried by the main shaft 44 of the stonecrusher as shown in Fig. 1. Thus the endless conveyer 22 is driven from the n'iechanism which operates the stone-crusher.

hi l6 indicate cables, the upper ends oi which are connected to the outer end. portions of the side members of the elevator frame. as shown in Figs. 1 and 2, and. pass between. the pulleys ill--20 and down to drums 4 -'l8 mounted on a shaft 49 which is suitably supported by the uprights 13-l'i, as shown in Fig. 3. Said shaft is provided with a gear 50 which meshes with a pinion 51 mounted on a stud said gear being pr vided with a hand-Wl'ieel 53 by which it may"be rotated. ".hus a Windlass is pro video. for drawing in or paying out the cables .257% and thereby raising or lowering the outer end portion of the elevator.

"""he elevator is pivotally connected with the uprights by means of straps 5%, one at each side, which .ut one end are connected with the side members of the elevator frame in line with the pivot 26 and at their other ends are connected with the uprights l3ll by pivots as shown in Figs. 1 and 2. straps, therefore, act links which afford a swinging or traveling connection between the elevator frame and the uprights 13-ll, causing the pivot 26 to swing in the arc of a circle about the pivots 55 a center. 56 indicates another pair of straps or links Which are pivoted at their upper ends to theuprights 13-4 1 by pivots 57, which; are placed lower than the pivots 55, as; shown in Figs. 1. and 2,

and at their lower ends the links are connected with the lower members of the elevator frame byl When the elevator frame is in its extended or oppivots 58 as shown in said figures.

erative position, the lower linlrs 56 are almost vertzcah-as shovn in Fig. i, butwhen the ele 'ator frame is folded Said links ex;

tend almost horizontally. as shown in Fig. 2,

carrying the lower portion of the elevator frame up bodily and moving it out into a substantially vertical position, as illustrated.

fill-60 indicate supports, preferably ers, which are carried by the uprights MB-i i preferably on brackets 61. in such position that they underlie the upper members of the elevator frame when folded, as sh wn in Figs. 2 and 3, thus supporting said irame when folded. Said rollers also serve to lolcrum the upper members of the-elevator frame when the elevator is being folded or swung back into inoperative position. For example, as the elevator is folded back at the hinged point. the members of the upper section strike and rest upon said rollers fill--00 which act as rolling fulcra for said members, and as the movement continues the lower section of the elevator frame autoshe ground; the

1 V l I l elevator as a. Whole being held and guided to proper position by means of the links 55 7-56. When the elevator is again raised to operative position, this movement is re -versed and the parts automaticallybrought to and securely held in proper position.

62 indicates a bail secured to the side mem bers of the elevator frame and extending at right angles thereto, as shown in Figs. 1

and 2, so that when said elevator frame is folded, as shown in Fig. 9., it will rest upon a portion of the stone-crusher 9 and assist in supporting the elevator frame. 63inchcates braces for said. baih From thev foregoing description it will be seen that when the elevator frame is in its operative position. the upper and lowermembers thereof are in line, the elevator frame being then supported by the cables 45-46 which bear upon the pulleys 20. The lower end of the elevator frame is hold in posui'onby the links M and the ends of the pivot 58 also engaging the uprights ill-1 as shown in 3. and sewing to prevent the lower end ol' the elevator frame from swinging in too far. In this position the lower portion of the elevator receives the discharge from the stone-crusher and ele' rates it for delivery. W hen the apparatus to be transported, by operating the WlI1Cllass the upper end of the elevator 18 pulled over toward the uprights and then swung ver, the cables running on the pulleys 19 until the parts finally assume the position.

shown in Fig. 2, the ca les. then running also on the pulleys 18. At the same timeithe lower members of the elevator frainez are automatically raised by the swinging. of'the upper member of the elevatorframe upon the rollers or supports lf 9-6ll as -ifulcra.in

themenner already described and are can ricd outward and upward by the links o l-56, as shown in Fig. 2, so that they assume a vertical position. When thopar s are fully folded, the upper members of the elevator frame arein a horizontal position resting on the bail (32- which engages a portionot' the stone-crusher. li/Wlll be apparient that after the elevator frame swings past the center in folding it is necessary (to 15 pay out on the cables in order toallow the upper members of the elevator frame to swing downward to their horizontal position, and that they'may be restored 'to their operative position by drawing in the cables until the upper portion of the elevator frame assumes a vertical position and swinging it past the center, when it will. again assume the position shown in Fig. 1'.

Instead of using the ha-nd'wheel' and spurgear shown in the draWings -any other suitable construction s nay be employed for actuating the hoisting devices, as, for instance, a worm and crank shown in Fig. l in which 641: indicates a cranlr operating; the-Won 1 65 nsea sary where the spur gear is used and making it impossible for a careless operator to drop the elevator to the injury of the elevator or of himself or others. In other respects also my invention is not restricted to the specific details shown and described, except in so far as they are particularly claimed, but in-v cludes generically the sub ect-niatterof the broader claims.
