Z '0 all witam it mafz/ Gomera:

Be it known that I, BRlT'rAIN F. WALsER, a citizen of the United States, residing at Vest Salem, in the county of Edwards, State of Illinois, have invented a new and useful Lifting-Jack; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same..

This invention relates to an improved lifting jack, particularly adapted for use. in connection with automobiles and the like.

As one of the objects of the invention, 1t is the aim to employ a plurality of lifting jacks of the kind hereinafter set forth, say for instance one for each end of each aXle of the motor vehicle, wherebythe Vehicle may be jacked up bodilytthereby pre- Venting the tires from contactmg with' the floor of the garage hence saving the tlres.

A further object lof the invention 1s to provide an improved lifting jack comprising a body having a guide therein, a lifting member mounted in the guide, and an eccentric member adjustably carried by the lifting member and adapted to cam on the shoulder of the body, for raising and lowering' the lifting member.

A further object of the invention is the provision of a detachable handle carried for Operating the said member, and which handle may be detached and used for removing and replacing tires upon automobile Wheels,

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In practical fields the details of construction may require alterations falling within the scope of what is claimed.

In the drawings Figure 1 is a view in side elevation of the improved lifting jack constructed in accordance With the invention.

Fig. 2 is a View in side elevation, showing the lifting member raised.

Fig. 3 is a View in elevati'on of the side of the jack opposite to that shownin Figs. 1 and 2, showing the lifting member raised.

Fig. 4 is a sectional view on line elf-4: of F ig. l.

Fig. 5 is a sectional view on line 5-5 of Fig. 2.

Fig. 6 is a detail perspective V1ew of the lever to be carried by the eccentric member.

' 7 may be lReferring more especially to the drawings, l designates, the body of the jack, which is constructed of three Sections, preferably of Wood and designated respectively by the numerals 2, 3, and i. The sections 3 and 4 are substantially triangular in side elevation, and are constructed. so that the grain of the Wood 'may extend Vertically. These Sections 3 and 4: are arranged, so that their adj acent Vertical edges are spaced from each other, and held so spa-ced by the section 2, through which and the sections 3 and a suitable rivets 5 extend, to hold the parts together. The section 2 is disposed so that the grain of the wood extends transversely of the grain of the Sections 3 and thereby preventing warping. By so spacing the Sections '3 and li a suitable guide 6 is provided for the reception of the liftin n. o n b section 7 of the jack.

This lifting section constructed of any suitable material, preferably wood or the like, and where this section is designed to engage the outer portion of the hub of the wheel of the motor vehicle, a suitable bearing member 8 may be attached, thereby preventing wear on the lifting section 7. member 8 may be removed, and dispensed with 1f deslred.

Secured by the rivets 9 to the sections 3 and a and spanning the guide 6 are the metallic straps 10, which act to holdthe lifting section in its guide. This lifting section is provided with a plurality of apertures ll, and designed to pass through any one of the apertures is a suitable screw 12, which is threaded into the disk or the lifting section actuating member 13. The section 2 of the body is construeted shorter than the sections ,3 and 4, and is disposed so that its edge 14 is arranged below the upper ends of the Sections 3 and 4-, thereby providing a shoulder. The screw 12 is threaded eccentrically into the disk or member '13 as shown. The disk or member 13 has two threaded recesses 15, either one of which may receive the screw 12, and in either case the disk or member 13 will be mounted eccentrically. That portion of the screw 12 where it passes through the lifting section -7 is cylindrical, smooth, and unobstructed, and a. trifie larger than its threaded part which is threaded into one of the recesses 15. By constructing the parts in this manner, the screw will readily turn with the disk or member 13, so that the screw will turn easily in its aperture of the However, this bearing' section 7 The outer face of the disk or member 13 has constructed thereon an elongated portion 16 provided with a tapered' tires. In jackingpup a motor vehicle one lever (whose handle end 19 vmay be employed for removingand applying tires to wheels) may be used for insertion into the socket of the disk 13 of each lifting jack, and after the jacks are set the lever may be detached. The lower part. of the body of the jack is provided with a laterally extending portion, forming a base 20, to prevent the jack from tilting.

The invention having been set forth, what is claimed as new and useful is 2- A lifting jack comprising a body consisting of a main V-shaped Wood section havin a lateral base at its lower portion, a pair of triangular shaped wood Sections secured on one face of the main section with .said apertures, whereby the marginal edge of the cam member may cam on the upper edge of the main section for raising and lowering the jack member, said cam member hiaving a socket for the reception of a hand e, diametricall opposite point to the engaging surface of t e cam will hold the vehicle in supported position and when the cam is moved to either side of a Vertical center line the weight of the vehicle will cause said cam to rotate and its frictional engagement at its lower edge will prevent the rapid lowering of the vehicle.

In testimony whereof I have signed my name to this specification in the presence of two subscribingwitnesses.
