'9.Glaims. (01. 214-131) Thisinvention relates toatta'chments for ve- 'locipedes, and, more especially, to a type of attachment which simulates earth-moving'devices commonly associated with'tractors, etc., which may be readily installed upon and removed from the standard form of tricycle.

It'is among the objects of'this invention: to

provide a deviceof this. kind that is of simpleryet durable. construction which can be readily applied to and removed from 'the'existing parts of v'eloci- *pedes without the attachment of extraneous permanent fixtures, and which is positive in action,

sturdy, and braced against unwanted movements.

'11; is another object to provide an attachment of by. reference to the accompanying: drawings i which: "Fig. 1 is a side eleva'tional view of anlattach- 'ment .applied .to a tricycle constructed in accordance with the present invention which shows the parts in the. 'lowermost operational positioniin solid .lines, and" "in-1' the uppermost t operational position in brokenxlines.

Fig. 8 is a plan view of a modifiedform oflever provided with a hoisting hook, while Fig. 9 is'a .side-elevational view of thisdevice'as'showrr in Fig. 8. I

In its preferred form, the invention comprises .a bifurcated lever 10*which is composed of'parallel legs and M- of some suitable material,

such as sheet metalor strap iron, which are connected. integrally at one extremity? by: a-crosspiece l6 andattheiropposite ends are formed into openloearings I81 and 20, respectively. The open bearings-are formed by: bending terminal portions-22 of the lever-'stockback upon itself so as' to leave a vertical opening 24in each' for the reception of a retainingcotter-pin26 whichfit 'to close the open bearings.

.The bearings themselvesare formed. by openings!!! whichi'are-cut from the folded edge of the :lever stock to a: size .which maybe accommodated upon the axle 29 of .a velocipede; as shown in Fig, 1. :At the opposite .end of the bifurcatedlever, the legs .IZ and. M .are provided. with" opposedi openings: 30 within which abheadeds pin 32 is adapted; to .pass. for retention. therein by a'nut 34.

*Thescoopis' composed of opposed side walls .36,aa?"bottom- 38, and arear wall-40' which .is notched at ll, Fig. 5,. to accommodate the pariallel-arms l2 and M: of .thebifurcated lever It. When. properly positioned, openings 42 in. the sides of the scoop are aligned with .theopenings '30 at; the end of the bifurcated lever and permit the scoop to be fastened in pivotal relation to the =latterby the insertionof the pin 32. A load in the scoopzis'poised by the bearing of the rear wall ez lllof .the scoop. at the openings 4| therein upon the undersides' of the legs [2 and I4 of the alever l0.

One'of-the legs 'I lv of the lever in adjacent its end containing the bearing 28. is providedwith a series of holes 44, 45- and 46,-which are adapted to; efiect pivotal engagement With a. toggle link 48 which is connected thereto at-its lower extremity bya pivot; pin of appropriate size. :The lower extremity of :the toggle link is also provided .withopenings 50v and 5| for cooperation with the

holes

44, 45 and." 46,.se1ectively-to varythe lever- I ageaand range of movement'of the bifurcated lever; and .to allow-adjustment tothe sizejof the vehicle of association. :This association of parts identifies thebifurcated lever ll) as a lever of the .thirdclass.

:At its-..upper end,.:the link .is connected to an actuating 'arm- 52;:which-is conveniently fashioned outof-a pipesection flattened atone end andwformedintoa bearing portion 54 within which. "the .handle' bar: or:other convenient element of :the 'velocipede overlying the axle constitutingv the fulcrumof thebifurcated lever on. the vehicle-is accommodated, and upon which it is --r.etained by aicotter pin 56 disposed across the bearing: 54* to close it. The pivotal connection 58.--.c.onnectsthe upper extremity-of the link 48 .with the actuating mechanism 52,which thus becomes a-leverof the second class. 'The relation- --ship .ofg:parts is :suchthat -the'pivot 58 orbits .around the axisof fulcrum of the-actuating arm 521toxap0int remote'fromthe pivotal connection 50 -.-between the link 43 and the lever I0, and wpas'ses beyond dead center efiectively to lookthe #parts-in the raised position shown in'b-roken'lines,

.an unbalance of its own mass.

so as to insure that it does not pass beyond the point where it will return to normal position by Thus, when the lanyard 60 is released, the scoop returns from the dumping position of Fig. 3 to that shown in Fig. 1.

In Fig. '7 there is illustrated a bulldozer

blade having bearings

72 and 14 for insertion between the arms l2 and [4' of the bifurcated lever. Openings 16 in these bearings are adapted to align with the openings 30 in the lever H! for accommodation of the pin 32 by which the bulldozer blade becomes rigidly attached to the lever.

Fig. 6, represents a rake

attachment having bearings

82 and 84 and openings 86 for use in connecting the attachment to the bifurcated lever w in the manner of that already described in connection with the bulldozer blades.

In Figs. 8 and 9, there is illustrated a modified form of bifurcated lever in which the

spaced legs

90 and 92 are provided with opposite ofisets 94, and contiguous portions 96 which are held togetherby rivets 98. At its outer terminal, the legs are opened by ofiset portions let for the accommodation of a hook I82 which is retained within the opening by pin I04 which passes through openings in the terminal portions of the legs and an eye upon the end of the hook. The hook is thus free to swing and pivot in response to changes in position of the lever. The same type of half bearings 28 are provided at the extremity of the

legs

90 and 92 of the lever shown in Figs. 8 and 9 as has already been described in connection with the bifurcated lever l0.

From the foregoing, it will be understood that the construction of this attachment is such as to.

28 of the bifurcated arms to permit these to be inserted upon the pedal axle 29 of a tricycle, after which the pins may be returned to their proper position in the vertical openings 24' to close the bearings. Correspondingly, the cotter pin 56 is removed to permit the insertion of the actuating arm 52 upon the handle bars of the tricycle, after which it is returned to close the bearing and to lock the parts in this relationship. The proper pivot point is selected between the link 48 and the lever in and the pivot pin is placed in position accordingly, after which thedevice is ready to be used. According to this arrangement, it takes but a matter of seconds to install the apparatus and to remove it when so desired. There is also great facility of interchangeability of the several implements permitted by removing the nut 34 and the pin 32 to allow for the association of the proper implements, after which the pin and nut '4 are returned to proper position and the attachment is ready for further use. Any appropriate form of implement is within the contemplation of the invention.

From the foregoing, it will become apparent to those familiar with this field of invention that many modifications may be made within the letter of this disclosure without departing from the principles of the invention which are not to be limited by the details asserted herein for purposes of description, but are to be accorded the broadest interpretation compatible with the recitations of the appended claims.
