' 'JNVENTOR 4? ar/0. BY I AT TORNEY such as will enable others skilled in the art UNITED "STATES I. PATENT OFFICEI I en'onenn. DILLON, or KANSASCITY, MIssoUnr I JACK;

T0 all'whom it may concern: I I 1 Be it known that I, GEORGE F. DILLON, a citizen of the United States, residing at Kansas City, in the county of Jacksonand State of Missouri, have invented certain new and 'useful Improvements l in Jacks; and I do declare, the following to be affull, clear, and exact description of the invention,

to which it appertains to makeand use the same, reference being-had to the accom panying drawings, and to the letters and figures of. reference marked thereon, which form a part of this specification. i g

This invention relates to jacks particu larly applicablefor use in raising motor vehicles and the like for inspection and re- P One of the objects ofthe invention is "to provide a jack whichmaybe conveniently of thefront end of the jack.

Fig. III 's a sectional view ofan oper ating lever; v n

Fig. IV is a detailedperspectiye viewof a jack in itselevated position. f i Fig. V isa longitudinal sectional view through the same, the wheels or casters be ing shown in elevation, and

Fig. VI is a top plan view of the jack. The jack is herein shown as comprising end of the body portion l'is hinged to a bracket comprising a vertical plate 4 and a forwardly disposed horizontal-plate '5, the

plates being joined in the form of an angle and pivotally secured to a lateral extension 6 of an angle journal bracket 7 having a vertical portion which carries the horizontal axle 8 upon which the front wheel:

or caster 9 is journaled. Journaled on" the same axle is a bracket 10 supporting a pivotally secured double toothed pawl 11 Application filed July I5, 1918. serial no. 244,931.

f and the other to the sliding rod 14 in Specification of was Patent. 2' P t fe May 9 1 j having a centrally located depending arm 12 to which a spring 13 is attached, oneend of the spr1ng13'be1ng secured. to the arm 12 1'5 and 16 onthe bracket 10. The rod 14 is prov ded with a handle extension 17 work- 111g in a guide 18 onthe ratchet actuating lever 19 on the bracket 10. The inner rim of the wheel 9 'is provided With ratchet teeth 20 adapted tobe engaged by either of the teeth on the pawl dependent upon the guides position of the spring which is adapted to be moved past the dead center by manipulationof t e'shifting rodwhereby the arm or lever 19 will be effective throughthe ratchet mechanism to turn the wheel 9 in either direction as will be presently explained. On'theiup'standing portion 4 of the bracket is a plate 21 having an inbent 11p 22'provided with an opening 23ffor'the.

reception ofthe notched portion 24 of the detent lever 25' pivoted. at 26 to the channelfl 1. When the parts are in'position shown in Figs. IV, V and VI, the notched lever 25 will hold the body portion of the ack 1n an elevated position'but when the notched portion 24 is out of engagementwith thelower edge of the opening 23, the

j ack will becollapsed as shown in Fig. 1'. 27 1s a spring adapted'to bear against the lower edge of -the detent lever .25'adjacent to tsnotch andthis spring has a tendency to move the'lever out of engagement with thelip 22. The jack may be elevated from its collapsed position by the spring retained tooth or extension 28 in the hollow lever 19. Theextension 28 is received within the hollever19 and is provided with an extension 29 to which one end of a spring 30 is attached, the other end being attached to the "lever 19 nearfits outer end. The shank 29 is, a body portion 1 shown as a channel hav- .ing upstanding webs 2 and 3. The forward provided with atooth or button 31 projectng through a slot 32 in the lever 19. The

pushing on the projection 31 to impart a longitudinal movement to the extension 28 the said extension will be projected far enough to permit it to engage the step or projection 33' which forms, a pivot for the vertically adjustable ember 34 of the jack.

The member 34 is shown asconsisting of 2 angle irons 35 and 36, the outer free ends of which support an elongated trough shaped jaw or seat 37 extending transversely of the jack. The seat 37 being designed to receive a horizontal axle as will be Well understood. The trough shaped body portion formed by the channel 1 constitutes a longitudinal guide for an elevating or wedge block 38 having a pull rod 39 extending between the lateral edges of the channel member 34. The rear end ofthe body portion l is supported upon a triangular frame d1 having wheels or casters f2 and 4:3 as is shown in Figs. IV, V and VI.

lVhen it is desired to use the jack for example, on a light car, the parts will be introduced adjacent to the wheel axle in a collapsed condition as shown in Fig. I.

The pull rod 39will then cause the wedge 38 to move forward so as to elevate the jaw 37 to bring it into engagement with the axle of the vehicle to be raised.

The extension 28 will then be moved'forward to engage the step or projection 33 whereupon pressure applied to the end PI of the rod 19 will cause the extension 28 to be tilted upwardly and raise the body portion to the position shown in Figs. IV, V and VIso that the notched portion 24 of the detent lever 25 will engage thelower edge of the opening 23 and lock the parts together. The axle of the motor vehicle will thereupon be raised and if it is-desired to move the motor vehicle this can be accomplished by pulling on the rod 19. If the motor vehicle is "too heavy to permit it'to be moved by pulling-on the rod 19, the slide rod 1& may be shifted so as to bring the proper tooth of the pawl into engagement with the teeth 20 and by moving thebar or rod 19 in an arc of acircle the jack may be moved over the surface and incidentally the car moved by means of the ratchet mechanism. The jack may belguided by swinging the wheel 9 either to the right'or to the left through the medium of the pivot 45 for the brackets I and 7.

If the car is too heavy to be lifted through the medium of the rod 19 alone an additional lifting lever 46 may be employedwhich may be introduced through the opening. d7 in the plate 21 when not in use.

Having thus described my invention, what I claim as newrtherein and desire to secure by Letters-Patent, is:

-1. A jack comprising a body portion, an axle-receiving member pivotally secured to the body portion, and a slidable wedge adapted to slide between the body portion and the axle-receiving member for adjusting the height of the ack.

2. A jack comprising a body portion of channel iron, a pivoted member on the body portion, a wedge between the'body portion and the pivoted member, an axle engaging jaw carried by the pivoted member, a wheel supported bracket pivoted to the front end of the bodyportion, a pivoted brace lever for holding the body portion and bracket rigidly together and a pivoted lever for raising the front end of the body portion.

A jack comprising a body portion consisting of an elongated member, wheels supporting one end of said member, a wheel at the other end of saidmember, a bracket supported by said wheel, hinged connection between the bracketand the member, a lever pivoted on the axle of the last named wheel, a spring-retained extension on said lever for engagement with a part of the member to raise the'member to horizontal position, a detent carried by the member and engageable with the bracket, and means operable by said lever for propelling said wheel.

4. In an automobile jack, a body'member, a forward member hingedly' connected to the body member, and a lever carried by the forward member adapted to engage the hinge connection to raise'the jack to functional position.

5. In an automobile jack, a body member, a forward member hinged to the body memher by a pin connection, an extension on the pin and a lever carried by the forward memher having a spring retained extension adapted to engage said pin extension to lift the jack to functionalposition.

In testimony whereof I afiix my signature.

GEORGE F. DILLON.
