, Application filed August a, 1913, Seria1 No.783,671.

. To all whom it may concern:

, Be it known that 1, JOHN HAnnrcAN, a citizen of the United States, and a resident of the city and State of New York, have invented certain Improvements in Lifting Devices, of which the following'is a specification.

' This invention relates to certain improvements in lifting devices, and more particularly in that class or type of such devices which are especially designed and adapted for use in connection with wheeled vehicles for lifting heavy loads, and the object of the invention is to provide a device of this general character of a simple and comparatively inexpensive nature, and of a strong and compact construction, capable of quick and convenient application in position for use without requiring any particular or especial skill on the part of the operator, and of such a nature as to permit of being operated from the movement of the vehicle to which it is applied for use, in order to dispense in great part with the manual labor and exertion ordinarily required for lifting heavy loads; The invention consists in certain novel features of the construction, and combinations and arrangements of the several parts of the improved lifting device, whereby certain important advantages are attained, and

Y the device is rendered simpler, less expensive, and otherwise better adapted and more convenient for use, all as will be'hereinafter fully set forth. I

The novel features ofthe invention will be carefully defined in the claims.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, 'wherein-' Figure 1 is a view in side elevation of a portion of a vehicle showing a lifting device embodyingmy invention applied thereto; Fig. 2is a view similar to Fig. 1 showing the-parts operated to lift a loaded receptacle and in such position as to permit the receptacle to beemptied within the vehicle; Fig. 3is a view in perspective with certain parts of the improved lifting device as herein disclosed omitted; and Fig. 4 is a detail fragmentary view showingthe device, in applied position, the wheel to which it is attached beingshown in section.

As shown in'the drawings, 1 denotes the body of a cartsupported by the wheel 2,

said cart being herein shown as of a type generally employed in various municipalities v self to the particular style-of vehicle with which the lifting device embodying my invention may be employed.

As hereln shown, the improved lifting device is provided with an'elongated lever member-'3, which may be formed from metal or other material possessing the requisite strength anddurability, and adjacent to one of its ends I have shown said lever member provided with reversely directed curved or angular wheel engaging jaws or members 4, 4, spaced apart one from the other in the direction of the length of said lever member, and adapted, when the latter is turned or adjusted at a slight angle to one of the spokes of the wheel to which the improved lifting device is to be applied for use, to be readily engaged with or disengaged from such spoke, the angular or overhanging formation of said aws 4, 4 being,

however," such that when the lever member is m ove d into line with the spoke to which it is applied, said oppositely arranged jaws 4, 4, a're clampingly engaged over the opposite sides of the spoke in such a manner as to lock the lever member securely thereto, so that said lever member will be carried upward say, from the lowered'or horizontal position shown in Fig. 1 to the raised or vertical position shown in Fig. 2 during the turning movement of the vehicle wheel. The length of the lever member, as herein shown, is such that when appliedto the wheel as indicated in Figs. 1 and 2, its outer end portion, opposite to that whereat the jaws or wheel engaging members 4, 4 are located, extends outwardly beyond the wheel rim in such a manner as to afford substantially a continuation or extension of the spoke, and in the embodiment of my invention herein shown, I provide this extended lever member is clampingly secured to a spoke of the wheel by engagement of its jaws 4, 4, therewith, a load may be quickly and conveniently raised into: position to be" dumped into, the vehicle by simple turning movement of the vehicle, wheel, ensuant upon forward movement of the vehicle itself, without any material physical exertion upon the part of the operator.

To further assure an effective engagement of the lever member 3 with the wheel 2, I provide intermediate the length of such lever a laterally directed jaw or member 5, extending in the same general direction as the jaws or members 4:, 4*, such member 5 being adapted to bridge or straddle and contact at the outer side of the felly G of the wheel, it being understood for conven ience of description that in referring to the felly the tire thereon is included.

As herein shown, the lifting device constructed according to my invention is par ticularly adapted to relieve collectors of refuse and the like from the exertion of the initial or straight lift required when the re ceptacles containing such refuse, particularly ashes or the like, are first elevated to be emptied within the body of the vehicle or cart, and as herein set forth the load receiving or supporting means at the outer end of the lever member 3 for engagment with such receptacles includes a lifting member or bar 7 pivotally or swingingly coupled with the outer end portion of the lever member 3 by means of a link connection 26, as clearly shown in Fig. l, the lower end portion of such bar 7 being provided with the hook member 8 adapted to engage the bottom flange 9 of the receptacle 10; but to afford secure engagement of said hook member and the bottom of the receptacle in case the lat ter may not be provided with a bottom flange, I have herein shown the free end edge of the hook member 8 serrated or notched, as at 11, whereby the bottom of a receptacle may be engaged by such hook member 8 without the possibility of the same becoming detached therefrom during the lifting operation, as is believed to be obvious.

By this construction, the direct strain of the lift will be upon the base of the receptacle 10, which arrangement I have found in practice to be of particular advantage. In order to maintain the receptacle 10 in en gagement with the hook member 8 and to assure secure engagement with such receptacles as may be provided with handles, 1 provide adjacent the upper end of the bar 7 the elongated ear or auxiliary hook member 12 extended in the same general direction as the bar 7, and positioned in a plane parallel therewith, which car or auxiliary hook member is adapted to be readily and conveniently passed through one of the looped handles or hand grasps 14 usually provided upon the receptacle or can 10,

herein shown as of the style or type gener ally employed in communities where regular collections of refuse are made. In the various styles or types of such receptacles or cans, I havefound that the distances be tween the bottoms of such cans and the to the hook member 8 a distance slightly less than the least known distance between the base of a receptacle or can and its looped handles or hand grasps, and have shown the ear or auxiliary hook member 12 terminating at a point relative to the hook member 8 a r distance in excess of the greatest known distance between the base of a receptacle or can and the looped handles or hand grasps ther of, the ear or auxiliary hook member being thus suitably positioned and made of a length suthcient to enable it to be engaged with the handle of the receptacle at whatever distance the same may be distant from the bottom of said receptacle.

In the employment of my device, it is only necessary that the lever member 3 be en gaged in a manner as has been hereinbefore set forth with a spoke 5 most convenient to the receptacle or can to be lifted, to pass the car 12 through one of the looped handles or hand grasps 1a; and to cause the hook member S to be engaged with the base of the receptacle or can 10 which may be accomplished by slightly tilting the receptacle, after which the draft animal is caused to advance sufficiently to bring the lever member 3 is a vertical position, the pivotal or swinging engagement of the lever member 3 with said lifting member or bar 7 permitting the latter, together with the can or receptacle engaged with the members 8 and 12, to be readily and conveniently turned in such direction by the operator or collector as will cause the upper portion of the receptacle or can 10 to span or bridge the space between the wheel 2 and the top or coping 16 of the cart or vehicle; and when the can or receptacle is in this position, it is apparent that the operator or collector, instead of being required to exert a direct lift, is permitted the advantage of a short leverage motion to empty the receptacle or can of its contents.

In order to obtain the best results, find it desirable that the supporting wheel 2 with which my invention is employed should 7e locked against rotation when the lever member 3 assumes a vertical position, and as herein disclosed I accomplish this result through the medium of a flexible member 18 possessing the necessary strength, and herein shown as a link chain, such connec tion having one end anchored as at 19 to the lever 3 at a point adjacent the member or aw 5 and having its opposite end terminating in a hook member 20 adapted for engagement with the tail 21 of the cart, the length of such connection 18 being such as to terminate or lock the rotary movement of the wheel 2, when the lever member 3 has assumed an upright position. In order 1 ,iemoaezpossibility of injury to such connection or member 18. As herein set fortlr, the device 22 terminates at each end in the hook like members 28, 23 in engagement with certainof the links 24, of the chain ina manner.

which is particularly set-forth in Fig. 4.

While I do not wish to limit myself to any particular arrangement for effecting the connection between the bar 7 and the lever 3, I prefer to employ the construction shown in the drawings, wherein acl' evi's- 25 is pivotally engaged with the outer end portlonof such lever 3, said clevis being connected with the upper end of the bar 7 by a link 26 passing therethrough and through an eye projecting from said arm 7.

From the foregoing description of my improvements, it is thought to be obvious that a lifting device constructed in accordance with my invention is of a simple and comparatively inexpensive nature, and is particularly well adapted for use by reason of the material lessening of labor required and by the facility with which it may be operated; and it will also be obvious from the foregoing description that my improved lifting device is susceptible of some modification without material departure from the principles and spirit of my invention, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.
