Application filed January 21,1207, Serial No. 353,322.

To all whom it may concern:

Be it known that l', OnilANDo iwnns, a citizen of the United States, residing atlmigmont, 'in the county of Boulder and State of Colorado, have invented a new and usefu-l Wagon-Loading Device, oi which the iollovring is a specification.

This invention relates to a device for taking up 1naterials, such as wheat, potatoes, and the like, in sacks,

. and beets, or other similar material, in bulk, and transuse, and adapted to enable a man to pick up heavy objects and place thegn in any desired place with considerablev ease and facility.

A further object of the invention is to provide a pair I of jaws suitably mounted upon a boom or lever which the operator controls from a suitable point, the jaws being opened and closed by an actuatingmechanism which is controllable from a point convenient to the operator. Y

Another object of the invention is to so mount the lift- 'ing boom orlevcr that it can be raised and lowered by means of a jack device carried bythe stand onwhich the boom is inlcrumed.

With these objects in view, and others, as will appear'- as-the nature of the invention is better undexstood,the invention comprises the various novel features oi eonstruction and arrangement of parts, which will be more fully described hereinafter, and set forth with particularity in the claims appended hereto. i

In the accompanying drawing, which illustrates one of the embodiments of the invention, Figure 1 is a pers ective View of Vthe loadin device showin f a ortion P g s P o the column of the stand broken away to illustrate the' details oi the jack device. Fig. 2 yis a fragmentary side elevation 0i the operators controlling device for the jaw operating mechanism. Fig. 3 is av transverse section of the handle end of the liitingever showing the jaw actuating device. Fig. 4 is a side elevation of the beef gathering jaws. Fig. 5 is`a 'transverse section j thereof.

Corresponding parts in 'the several figures are indicated throughout by similar characters of reference. Referring to the drawing, l. designatesthe lifting lboom or lever ofthe apparatus which is hinged at 2 on the upper end of alvertically disposed pivot 3 mounted inthe stand, designated generally by 4. The stand compris-es a hollow column 'or post 5 provided at its i lower end with asuitablcbasc, such, for instance, as

l i l l i i i I be moved about the vertical axis oi the legs l, whereby the upright or column 5 is supported in a vertical position. The pivot 3 is provided with a shoulder or collar? which is adapted, when the lever l is in its lowcrini'ist position, to bear on the upper end oi the upright 5. By this means, the lifting llever 1 can stand and also tilted on the horizontal pivot 2.

ln some circumstances, it may be desirable to vary the height oi the pivot 2 on which the lifting lcvcr 1 load wagons of different heights. For thispurpose, a mechanism for adjusting the pivot 3 is employed,y the saine comprising a pawl 8 having ahandle 9 and. ar-

ranged to engage ratchet teeth lOpn the pivot 3, a spring actuated pawl l1 cooperating with the pawl 9 to permit the pivot'irto he raised or lowered step by step.

swings, as, for instance, to accommodate the device to The pawls are fulerumed on lugs 12 formed on the up- -right 5, and adjacent the lugs are slots 13into which the pawls extend to.eugage`the ratchet teeth on the pivot. The pawl 8 is provided with a slot 14 through which the fulcrum pin 15 extends, the slot permitting of the pawl beingmoved back and orth as it is worked from one tootlrt'ol another. In order to permit the pivot 3 to be turned, while itis held in position by the pawl 11, the ratchet teeth l0 are circular and extend entirely around thelpivot. By means of this jack device, the

lifting leveror boom 1 can be readily and conveniently l' raiscd'or lowered on the supporting stand 4 to any de,

' sired position.

The lifting lever or boom 1, which may be of any desired construction and of suitable proportions, carries at one end a pair of scooped-shaped jaws 16 which are approximately semi-cylindrical in shape and hinged together at 17. Each jaw is provided with an arm 18 arranged at the middle thereof and extending between the bifurcations 19 of the lever l. The .jaws are so arranged that the arms 18 cross each other aiterthe fashion oi a pair of tongs, and are hinged to the lever 1 by the pin 20. The upper ends of the arms 18 are connected by toggle links 2l which are straightened and collapsed by the bell crank lever 22 fuleruinecl on the,

lever 1 adjacent the jaw carrying end.. The tilting of the'boll crank lever 22 actuatcs the toggle links 21 so that the jaws 16am either opened or closed, so that articles can be picked up thereby and deposited. The bell crank lever is actuated by a pitman or connecting rod 23 which extends approximatelyfrom one endof the connecting lever l to the other. At the end of the lever 1 opposite from that carrying the jaw 16 is a handle 24, and adjacent this handle is a controlling device, designated generally by 25,1`for moving the pitman 23 longitudinally hack and forth to open and close the jaws. This controlling device comprises an arm 26 iulcrumed at 27 on the handle end of the lever 1 and pivoted at 28 to the pitman. Hence, by oscillating the ar1n'26, the pitman will be moved in one direction or the other. In order to lock the arm 26 in eitiher of its two positions and thus hold the jaw 16 open or closed, the latch 29 is i'ulcrumed at 30 on a lug 3l formed on the The latch is provided with a projection 32 which-engages in the upper opening or depression 33 when the jaws are open, and in the lower' opening or depression 34 when the jaws have been moved to closed position, as shown respectively by the full and dotted lines in Fig. 2. v

When the lever l has been adjusted to such a height that it is not convenient for the operator to reach the handle 2o, the said lever can be moved by the operator taking hold )if the auxiliary or secondary handle 35.

' The said auxiliary handle comprises a vertically ex,-

tending inomlierti that is ',treelymovable through an aperture in the handle 24f/'and at its lower end carries a grip mornber lor lrandhold 37. On the upper end oi the member 36 is aprojeetion 38 forming a stop for preventing the auxiliary handle from pulling out.

in, operation, the lever' l. is first adjusted by means of the jack device on the stand 4 to the desired position, and the stand is placed in suitable proximity to the wagonor other place where the material is to be doposited, and also in suitable proximity to the material to be taken up by the device and transferred to the wagon. ll`he operator then takes the main or auxiliary v handle oi the lever' in one hand and with the other operates the latch 29 and cout roller arm 2G. By loosening the latch and throwing thc arm 2G toward the stand 4, the jaws are opened by the intervening connections. 'lhe lever' l is next tilted so that the jaws can take upa sack or any bulk material on the ground and the latch is again released and the arm 2G swung in thc opposite direction. lly this operation, the jaws are closed upon a sack or whatever other object-is to be lifted. The operator then pulls down on the handle end ol' 'the lever l and at the same time swings the lever around on the pivot 3 as an axle so as to throw the jaw end of the lever over the body ol the wagon into which the jaws are to empty. While being held in this position, the latch 29 is again released, and the arm 2G moved toward thev stand 4, thus causing the jaws to open and the contents thcreol to be deposited into the wagon. The lover l is then swung back and lowered to itsvinitial position to take up another sack and transportit to the wagon, and so on, imlcfinitely.I It will thus be seen that/thelitting and transporting oi' suitablelmaterial from -place to place can be conveniently and (prickly accomplished by means oi the iinproved device.

The preferred form oi jaws for use with the apparatus when handling beets and similar loose products is slroW-n in Figs.A ll` and 5. These jaws each comprise a plurality ol spaced curved teeth connected or formed integral with a cross bar 40, and the inner' ends o the teeth Il!) ol both jaws overlap and are connected by a pintle 4| so as to hinge open or closed. The central teeth are provided with arms 42 through which the pintle passes, and these arms serve to connect the jaws with the toggle links 2l of the device. These beet gathering jaws and the sack gathering jaws Shown in Fig. lare intended to be used interchangeably, and to detach one set of jaws and apply the other, it is merely necessary to remove the pins 4.3, Fig. l, which connect the arms of the jaws with the toggle links 2l., and substitute the jaws desired.
