Application May 4, 1933, Serial No. 669,393

1 Claim.

This invention relates to a gauge, the general object of the invention being to provide a gauge for facilitating the setting of anchor pins of hydraulic brakes when relining brake shoes.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or'corresponding parts throughout the several views, and in which:-

Figure 1 is a view of a hydraulic brake, showing the gauge in use.

Figure 2 is a plan view of the gauge.

Figure 3 is a perspective view of the gauge, with parts broken away.

As shown in these views, the numerals 1 and 2 indicate a pair of substantially L-shaped members formed with a shank 1' and a head 1", each head having a notch 3 therein. Each shank is formed with a threaded hole for receiving a screw 4 which passes through the slot of a plate 5 which rests on the shanks and a washer 6 is placed between the head of each screw and the plate.

The notches are shaped to fit the pins 7 which pivotally connect the brake shoes A to the drum B, as shown in Figure 1. As is understood, the pins 7 must be replaced, when removed from the brake assembly in the same position that they originally occupied and this device facilitates the placing of the pins in their original position.

In using the device and before the brakes are removed, the members 1 and 2 are placed over the pins 7, as shown in Figure 1, after the screws 4 are loosened and after the members are placed over the pins, the screws are tightened to hold the parts in adjusted position. The device is then removed from the pins and set to one side and then the pins are removed so that the brake shoes may be removed and relined or repaired. When the brakes are put back in position, the anchor pins are put back in place, but their lock nuts are left loose so that the pins can be adjusted to fit the gauge, it, of course, being understood that the gauge is picked up and placed over the pins after they are adjusted to fit the gauge. When the pins are so adjusted, the lock nuts are tightened and then the gauge can be removed. Thus the device will enable the pins to be placed in the exact position they occupied before they were removed.

In order to facilitate the placing of the gauge on the pins, one of the members provided with the notches should be marked with the numeral 1 and the other with the numeral 2 and the pins 7 should also be marked with the numerals 1 and 2 so that the member marked 1' can be readily placed on the pin marked .1 and the member marked 2 on the pin marked 2.

This gauge eliminates guess work for the mechanic and also saves time.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that-changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is:-

A gauge of the class described comprising a pair of members, each having a shank and a head, said head extending from one side of an end of the shank, each head having a notch therein which extends at right angles to the length of the shank and opens out through the free side edge of the head, an elongated plate having one face contacting and overlapping the two shanks and having an elongated longitudinally extending slot therein, the ends of which extend over the shanks, and screws passing through the slot and threaded into the shanks for slidably and rotatably connecting the shanks to the plate and for holding the pair of members in the position to which they have been adjusted when the screws are loosened.
