AUTOMOBILE-JACK.

Specification of Letters Patent.

Patented Feb. 28, 1911.

Application filed March 4:, 1910. Serial No. 547,265.

To all whom it may concern: Y

Be it known that I, \VILLIAM F. SCHREI- mm, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented a new and useful Automobiledack, of which the following is a specification.

This invention relates to jacks especially designed for use in connection with automobiles.

It is a well known fact that when automobiles are used for display purposes within sales-rooms, the tires thereof often become injured because of the constant unshifting weight to which they are subjected and because of the further fact that they become flattened because of deflation.

One of the objects of the present invention is to provide a jack particularly designed for supporting an automobile out of contact with the surface upon which it is mounted, the jack being of a simple and compact construction and easy to operate.

A further object is to provide a device of this character which can be readily adjusted for use in connection with wheels of different diameters.

lVith these and other objects in view the invention consists of certain novel details of. construction and combinations of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings the preferred forms of the invention have been shown.

In said drawings :Figure 1 is a side elevation of a jack constructed in accordance with the present invention the position of said jack immediately prior to the elevation of the wheel being indicated by full lines and the relative positions of the parts, when the wheel is elevated, being indicated by dotted lines. Fig. 2 is a plan view of the jack showing the parts in their normal positions. Fig. 3 is a section on line i k-13 Fig. 2. Fig. 4 is a detail view of the hub engaging block of the jack. Fig. 5 is a transverse section through the block. F O is a perspective view of a portion of a modified form of jack.

Referring to the figures by characters of reference 1 designates the base of the jack,

the sides thereof preferably converging toward one end and each of said sides being provided with a longitudinally extending shoulder 2 inclined downwardly toward the small end of the base.

Eyes 3 or the like are arranged upon the base and a rod 4: extends through them and projects into opposed portions of a bail 5 constituting the actuating lever of the jack. Each end of the bail has an arm 6 extending therefrom and the said bail, when in its lowermost position, is designed to rest upon the shoulders 2 and thus support the arms 6 in inclined positions as shown by dotted lines in Fig. l.

The arms (3 are formed with apertures 7 each of which is designed to receive a trunnion 8 extending laterally from the lower end of a frame member 9. These frame members converge upwardly and merge into parallel extensions 10 designed to rest within grooves 11 formed longitudinally within the sides of a hub engagin block 12. The ends of this block are prererably concaved as shown at 13 and extending through the block from one groove 11 to the opposed groove, is an opening 14:. This opening is located nearer one end of the block than the other and is adapted to receive an arm 15 extending at right angles from the extension 10 of one of the frame members 9. The free end of the arm 15 is adapted to project into an eye 16 formed at the free end of the extension 10 of the other frame member 9 and this end of the arm is preferably screw threaded and adapted to be engaged by a nut. 17. Vhen this nut is tightened on the arm 15 it serves to draw the two extensions 10 tightly into the grooves 11 and thus hold the block 12 securely fixed relative to the frame members 9.

In using the jack the broad end of the base 1 is placed close to the lower portion of the wheel and the bail 5 and frame members 9 are swung upwardly so as to thus lower the arms (3 and bring the block 12 under and close to the hub of the wheel. This hub has been indicated at C in Fig. 1. The bail 5 is then swung down onto the shoulders 2 and this causes, the arm 6 to swing upwardly and outwardly and the block 12 is therefore pressed upwardly againstthe hub and will lift the wheel oil of the floor. The frame members 9 will swing laterally at their lower ends and it will be apparent t-l'lerefore that the jack will lock itself so as to prevent the wheel from returning to its lower position as long as the bail 5 rests on 'wardly toward the wheels the shoulders 2. Obviously by using one of these jacks in connection with each wheel of the automobile, the entire machine can be held off of the floor or ground.

is heretofore pointed outthe arm exten ls through the block 12 at a point nearer one end than the other of said block. it will be apparent therefore that with one end of the block uppermost the jacl; will be adapted for use in connection with a wheel of one diameter, while, by loosening the arm 15 and reversing the block and then tightening the arm. the jack can be used with a wheel of another diameter.

instead of utilizing a reversible block such ...i, I as snow 11 in 1gs. to lntiusn e, tne aims ti an be arranged to IQL'OH'Q a rod 18 on the ends of which are mounted the ends of a frame 19 carrying a yoke 20 adapted to engage the wheel hub. The said frame may be provided with one or more openings in each end thereof and the rod can be extended through any of these openings so as to adapt the jack for use in connection with wheels of different diameters.

It will be seen that a jack such as has been described is very simple in construe tion. durable and inexpensive and can be readily actuated. By reason of the peculiar arrangement of the parts the automobile or other vehicle supported thereby is prevented from shifting laterally. masnnich as the frame members 5) wlich are inclined upsupported thereby, serve to prevent lateral movement. Importance also attached to the fact that the jack is very light and can therefore be easily -arried and placed in position.

Various changes can of course be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as defined in the appended claims.

hat is claimed is 1'- l. A jack including a base having inclined side shoulders, a bail like elevating device fulcrumed on the base and normally embracmg said base and bearing on the shoulders, arms upstanding from said device, and a wheel engaging element adjustably connected to the arms. s

2. A jack including a base, an elevating element. thereon, frame members extending from and adapted to be shifted by said element, and a wheel engaging device mounted between said members, said device being reversible to vary the distance between its upper end and the base.

A jack including an elevating lever, opposed frame members pivotally connected thereto, an arm upon one of the members and detachablyengaging the opposed member, a reversible wheel engaging block mounted ot f center upon the arm, said block having opposed grooves for the reception of the "rame members, and means engaging the arm and one of the frame members for binding said members'within the grooves to hold the block against movement relative thereto.

4. A jack including a base having inclined side shoulders. a bail-like elevating device fulcrumed on the base and normally embracing said base and bearing on the shoulders, nmvardly converging frame members pivotally connected to the elevating device, and a wheel engaging element carried by said members.

5. A jack including converging frame members, a reversible wheel engaging block interposed between the members and having grooves for the reception of said members, means for securing the members within the grooves, a base, and means upon the base for elevating the frame members.

In testimony that I claim the foregoing as my own, I have hereto atlixed my signature in the presence of two witnesses.
