APPLIANCE FOR LIFTING-JACKS.

Specification of Letters Patent.

Patented Sept. 27, 1910.

Application filed June 22, 1910. Serial No. 568,329.

To all whom it may concern:

Be it known that I, ANTON W. SALLAN- mm, a citizen of the Unlted States, residing at Fort Madison, in the county of Lee and State of Iowa, have invented a new and useful Appliance for Lifting-Jacks, of which the following is a specification.

It is the object of the present invention to provide an appliance for lifting jacks intended primarily for use in connection with automobile jacks. It is well known that the majority of types of automobiles have a truss rod extending beneath the rear axle so that the head of a lifting ack can not be disposed directly against the under side of the axle but must be placed beneath one of the bolts thereof or beneath some other projecting part. hen so disposed, there is every likelihood that the jack will tilt thereby allowing the machine to drop.

The present invention therefore aims primarily to provide a device which may be disposed upon the head of an ordinary lifting jack such as is employed in lifting or jacking up the axle and body of an automobile, and will be so constructed as to straddle the truss rod before referred to and bear directly against the under side of the axle.

The invention further aims to so construct the appliance that the truss rod will be held between portions of the device so that tilting of the jack or the device itself is rendered practically impossible.

In the accompanying drawings, Figure 1 is a perspective View of the device embodying the present invention in use. Fig. 2 is a view in side elevation of the device. Fig. 3 is a plan view thereof.

In the drawings, for the purpose of illustrating the utllity of the device, there is illustrated, in a general manner, the rear axle 5 of an ordinary automobile, the truss rod 6 which is usually to be found extending beneath such an axle, and a spring-attaohing sleeve 7 held in place by a bolt 8 secured through ears 9, this sleeve embracing the axle 5 in the usual manner. There is also shown the upper end or head 10 of an ordinary lifting jack.

The device embodying the present invention, while it may be cast if desired, is here shown as formed from a length of stout bar metal which is bent upon itself at a point midway bet-ween its ends as at 11 to aflord diverging arms 12, these arms being relatively laterally off-set as is clearly shown in Fig. 3 of the drawings. Each arm, at its upper end, is formed with a portion 13 bent to project in the general direction of the other arm 12 and this portion 13 of each arm constitutes a supporting portion and is bent, preferably in the arc of a circle, as is shown in Fig. 2 of the drawings, with its concaved side presented uppermost. Upon this side of the portion 13 there is secured a strip of leather indicated by the numeral let which strip serves to prevent marring of the axle 5 or the sleeve 7 depending upon which one of these elements the device is disposed against.

The portions 13 of the arms 12, it will be observed from an inspection of the drawings, are correspondingly curved so that they will fit the axle 5 or sleeve 7 in a like manner. It will further be observed from an inspection of the drawings that both portions 18 are of such length that they project beyond the vertical medial line of the device so that the device can not be engaged over the truss rod 6 by direct upward movement but must be turned so that this rod may enter between the opposing edges of the two portions 13 after which the device is again turned so that these portions will project above the rod 6 at right angles thereto. hen the device is caused to assume this latter position, the rod 6 will be frictionally received between the diverging arms 12 and inasmuch as the portions 13 have engagement against the under side of the axle, the rod 6 is so confined between the arms 12, that tilting of the device is rendered practically impossible. It will be readily understood of course that the apex of the device constitutes the base thereof and is disposed upon the upper face of the head 10 in the position shown in Fig. 1 of the drawings.

From the foregoing it will be appreciated that whereas ordinarily the head 10 of the jack is disposed beneath the lug or ear 9 or some other projecting portion of the vehicle body or axle or parts connected therewith, in this instance, the axle is supported upon the device of the invention which device has direct downward bearing upon the jack. As a consequence, tilting of either the device or the jack is rendered extremely unlikely.
