JACKSON, MICHIGAN, .ASSIGNOR T0 JACKSON MACHINE 6t TO OL COMPANY, A CORPORATION OF MICHIGAN.

PERCH FULLER.

Application filed April 27', 1925.

This invention relates to perch pullers and the like.

The perch on various makes of automobiles, and particularly on Fords, must sometimes be removed for attachment of shock absorbers, repairs, or for various other reasons, inasmuch .as these perches which pass through the front axle, are exposed to the mud, dirt and weather, they very often become rust-ed and corroded in the axle, making it very difficult of removal excepting by means of a heavy jar such as .a hammer blow or some other force. Hammer blows would destroy the thread on the lower end of the perch, as well as slightly heading over the end, making it very difficult to withdraw through the opening of the perch, and precluding the possibility of again using it when reassembling.

One object of the invention is to design a perch puller adapted to be attached to the lower flange of the axle, which will have sufficient leverage to start and remove the perch without distorting the threads, or otherwise injuring the perch proper.

Another object is to provide a perch puller of simple and substantial construction which is easy to operate, and economical to manufacture.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawing, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion and minor details of construction, without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing Fig. 1 is a sideview of my improved puller showing it in place on the front axle of an automobile;

Fig. 2 is an edge view thereof, and

Fig. 3 is a bottom view of the perch puller.

I am aware that other perch pullers have been designed and are at present on the market, these however engage the top flange of the axle, and any slight variations out of the direct vertical alinement of the tool with relation to the top flange or perch, has a tendency to bind the perch in the axle, making it very difficult for removal. This Serial No. 26,117.

I have overcome by engaging the bottom flange of the axle, assuring positive alinement when pressure is exerted by the operator,

Referring now particularly to the drawing in which I have shown the preferred embodiment of my invention, the numeral 1 indicates the main body portion which I prefer to make a forging, the one end being cylindrical in shape, the opposite end terminating in spaced apart jaws 2 adapted to grasp and engage the lower flange of the axle member 3. Perches 4: are mounted in suitable openings provided in the axle, and are held in position by means of a nut (not shown), which is threaded on the threaded end 5 of the perch.

A. centrally disposed threaded opening 6 extends through the main body, and is adapted to receive the screw threaded thrust rod as shown, and which is provided with a head 8 having .a transversely disposed opening 9 therethrough, adapted to receive a rod or bar 10, and which serves as a handle for turning the thrust rod. The opposite end of this thrust rod is turned to a smaller diameter as shown at 11, and is not threaded, a tip 12 being formed on the extreme end for engaging the end of the perch. This turned end enters the opening in the axle as the perch is being forced out, and there can be no marring or binding of the perch or thrust rod.

The flanges on the axle are narrower at the center than at the ends, and in operation the perch puller is placed over the axle flange near the center of the axle. The operator then slides it along until it is positioned directly beneath the perch (the nut being removed). The thrust rod is then turned until the end engages the end of the perch, when continued rotation forces it from the opening.

From the foregoing description it will be obvious that I have perfected a very simple and eflicient tool for removing perches from automobile axles.

What I claim is 1. A perch remover adapted to be attached to opposite sides of the lower flange of an automobile axle of I-beam cross-section, and comprising an elongated cylindrical body having spaced-apart arms terminating in jaws, a threaded opening through said body, a thrust rod therein, one end of which is i 7 said thrust rod.

2. A perch puller adapted to be removably attached to opposite sides of the lower flange of an automobile axle of I-beain crosssection, and comprising an elongated main cylindrical body, outwardly extending arms terminating in spaced-apart jaws formed integral therewith, a thrust rod threaded in said main body and having a reduced end of a length equal to the depth of the axle and a transversely disposed handle extending through the head of the thrust rod.

In testimony whereof I afiix my signature.
