A. W. NEWMAN JACK uuuuuuuuuunnunnnm: if I 0 I 3 Filed y 1 1928 Patented June 17, 1930 UNITED STATES ARNOLD w. NEWMAN, or ALVIN, 'rExAs JACK Application filed May 17, 1928. Serial No. 278,371.

This invention relates to new and useful improvements in a jack.

One object of the invention is to provide a tool of the character described specially designed for use in connecting a motor vehicle spring to the shackle by means of which the spring end is connected to its perch.

In repairing the springs of certain types of motor vehicles it is sometimes necessary to disconnect the ;spring end from the shackle by means of which it is connected to the spring perch and when the repairs have been made it is quite difficult with the tools now in use, to reconnect the spring end to its perch. The jack herein described is intended for use in making such connection.

Another object of the invention is to pro- 20,vide a jack of the character described which is of simple construction, may be cheaply produced and is very efiicient in use.

With the above and other objects in view this invention has particular relation to certain novel features of construction'operation and arrangement of parts an example of which is given in this specification and illustrated in the wherein Figure 1 shows a plan viewof the jack. Figure 2 shows a longitudinal vertical sectional view thereof as applied in use, and a Figure 3 shows a cross sectional View thereof.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures the numeral 1 designates the frame of the jack as a whole. This frame has the downwardly turned

end flanges

2, 2 forming supporting legs whose lower ends accompanying drawings,

have arcuate seats3, 3 designed to rest on the vehicle axle, 1. The frame also has the depending

side flanges

5, 5. The frame has a long longitudinal slot 6 therein and slidably mounted on the frame there is .a head 7 which is confined to longitudinal movement on the .frame by means of a set screw 8 whichis fitted upwardly through said slot and is screwed into said head and the head of thisset screw engages the under side of the. frame and prevents the detachment of the head 7 from the frame. 7

Upstanding from one end of the frame there is a holder 9 having the top and side-fian'geslO and 11, 11 respectively. Seated in thisholder, between said flanges, there is a nut 12 which is held against turning by said holder. A jack screw 13 is threaded through said nut. and works loosely through'anopening 14; inthe holder. The outer end of this jack screw has a. polygonal head 15 to' receive a wrench by means of which it may be turned and its other end has a swivelling connection with the head 7. The jack may be mounted on tlie axle 4, at the desired place, with its legs 2 resting on said axle. The jack may be secured in place by, means of the.

side links

16, 16 whose upper endsare connected to the

side flanges

5, 5 and whose lower ends are fitted through end bearings in the cross yoke 17 and are threaded to receive the

clamp nuts

18, 18 which retain the yoke on said links.

The links are arranged one on each side of the axle 4, with the yoke clamped against the under side of said axle.

The jack, as so located, is so disposed that the head 7 may be engaged against-the inner side of the end bearing 19 of the leaf spring 20, of the vehicle. The jack screw 13 may now be turned so as to force the end of the spring outwardly into such position, relative to the corresponding spring perch 21, that the connecting Ishackle may be readily: connected to said spring end and perch.

While the jack has been shown as applied to the work of connecting a spring of an automobile to itsshackle it is also capable of other similar uses.

It is obvious that mechanical changes may be made and equivalents substituted for the parts shown and I reserve the right to make such changes and substitutions within the scope of the appended claims.

What I claim is r l. A jack including a frame adapted to be mounted on a vehicle axle, a head movable on the frame, a holder carried by and upstanding from the frame, said holder having overturned top and side flanges, a nut in said holder held against turning by said flanges, a jack screw threaded through said nut and having a swivelling connection with. said head.

2. A jack including a frame adapted to be mounted on a vehicle axle, a head movable on the frame, a holder carried by and integral with the frame, a nut in said holder, a jack screw threaded through said nut and having a swivelling connection with said head, legs depending from the frame and formed with arcuate seats to receive said axle, and means for securing said frame to said axle.

3. A jack including a frame having end legs for supporting the frame on a vehicle axle, and formed with arcuate seats to receive said axle, a head movable on the frame, a holder on the frame, a nut in said holder, a jack screw threaded through the nut and connected to said head, and means for clamping said frame onto said axle.

4. A jack including a frame formed to fit on a vehicle axle, a head movable on said frame, a jack screw operable against said head, a holder upstanding from the frame and having overturned flanges, a nut between said fianges with which said screw has a threaded connection, means for clamping the frame onto said axle, said clamping means including a yoke and side links connected at one end to said frame and at their other ends to the respective ends of said yoke.

In testimony whereof I have signed my name to this specification.
