VEHICLE JACK.

Application filed October 23, 1925. Serial No. 64,408.

The present invention relates to improvements in jacks designed for lifting vehicle wheels from the ground when the changing of tires or other Work is desired.

The principal object of this invention is the provision of a jack so constructed that two spaced supports are provided for supporting-a vehicle axle, whereby danger of slippage or breakage of the jack will be reduced to a minimum.

A further object of this invention is to provide a device of the character described which is simple in construction, economical to manufacture and which may be easily and quickly positioned under an axle.

An additional object is to provide a device of the character described which will serve to raise the axle by a simple single movement of an operating lever and to further provide a device which can be readily adjusted to the desired height by a simple manipulation of thejack.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same.

Figure 1 is a side elevation of the device constructed in accordance with our invention,

Figure 2 is a plan view of the same,

Figure 3 provided with ratchet teeth,

Figure 4 is a side elevation of the jack showing the same in operative position with a portion of the standard in section,

' Figure 5 is a detail view disclosing the standard with the bar positioned therein,

Figure 6 is a similar View with the bar removed,

Figure 7 is a transverse vertical section through the standard and bar, the view being taken on the line 7-7 of Figure 8, and

Figure 8 is a plan view of the standard with the bar shown at right angles to the position of the bar as shown in Figure 5.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of our invention, the numeral 9 indicates a base which has mounted thereon a tubular standard 10 and an extension 11, while the numeral 12 designates an operating lever equipped at one is a sectional detail of the bar end with a handle 13 and being curved adjacent its opposite extremity and having a depression 141 formed therein for preventing displacement of the front axle A. when the jack is in operation.

Pivotally secured to the curved end, as'at 15, is a supporting member 16 which has formed on its lower extremity a shoulder 17 adapted to contact the extension 11 in the operation of the jack.

The numeral 18 designates a bar being pivotally secured as at 20 to the lever 12. It will be noted that this bar is substantially rectangular in cross section and has the ratchet teeth formed on the opposite sides thereof, whereas the opposite faces of the bar present flat surfaces. The standard, above referred to, is slotted as at 22 and has its free extremity crimped or re-enforced so as to provide. shoulders 23. These shoulders serve to engage the teeth of the bar when the ack is in operation, while the construction of the bar with its fiat faces permits a free vertical movement of the same in the standard when an adjustment relative to height is desired.

In the operation of the jack on the front axle A, the desired elevation is first obtained by turning the jackbody at right angles to the rest of the assembly or by turning the lever 12, as disclosed in dotted lines in Figure 2. After the desired height has been realized, the supporting bar 16 assumes the position shown in Figure 1 and certain of the teeth will engage the shoulders 23. Downward pressure on the operating lever willcause the axle which has been received in the depression is to be raised, whereupon the vertical wheel will be lifted and the desired work performed.

The bar 16 when in the position shown in Figure 1, together with the bracing efiect caused by the contact of the bar 18 with the shoulder of the tubular member will afford a positive and strong support. If a raising of the rear axle B is desired, it is only necessary, after proper adjustment has been made relative to height, to exert downward pressure on the lever 12 until the extension 11 has been received in the shoulder 17 of the supporting member 16.

After the lever has been released the axle will be suitably braced with two supports instead of with a. single support as is now obtained in the ordinary jack.

It is to be understood that the form of our invention herewith shown and described is to be taken as a preferred xample of the same and that various changes in the shape, size and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described our invention, We claim A jack comprising a base, a standard supported on said base and having, shoulders formed on its upper extremity, an extension formed on said base and spaced from said standard, a lever embodying in its construction a handle on one end and being curved adjacent its opposite end with a depression formed therein, a bar pivotally connected to said lever adjacent the curved portion thereof and provided with a plurality of teeth formed on the opposite faces of said bar for engaging the shoulders of the standard, and a supporting member pivoted at one end to said lever and having a shoulder formed in its opposite end for engaging said extension.

In testimony whereof We aifix our signatures.
