SPECIFICATION forming part of Letters Patent No. 460,434, dated September 29, 1891.

Application tiled March 27, 1891. Serial No. 386,675. (No model.)

axle-gages; and the object of myinvention is to provide a simple and convenient device which will accurately test an axle to indicate whether'it is properly turned and the wheels properly set thereon, and which may also be used as a straight-edge and rule.

To this end my invention consists in an axle-gage constructed substantially as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the gage, showing its application to an axle. Fig. 2 is a broken enlarged plan view of the gage. Fig. 3 is an enlarged detail side elevation showing one ofthe sets in position on the bar, and Fig. 4 is a cross-section on the line 4 4 of Fig. 3.

The gage comprises the flat bar 10, the slid` ving sets 11, which move on the bar, and the means for adjusting the sets. The bar 10 is made, preferably, of flat steel, and is provided throughout its entire length with gage-marks indicating the fractional parts of inches, and the marks maybe produced so as to measure the smallest practical fraction of an inch, if desired.

The sets 11 are provided with four flat faces 12, which are placed equidistant around the periphery of the sets, and three ot the faces of each set are provided with set-screws 13, 14, and 15, the fourth face being provided with a thu mb-screw 16,which projects through the set and impinges on the bar 10, so that vby tightening the thumb-screw the set may be held in a desired position on the bar. The set-screws are accurately adjusted by means of a small wrench, so thatl the outer ends of the set-screws 14 will be level. The setscrews 13 are adjustedl so that the screws in the middle set-screws, so that when the mid` dle set-screws are against the arms of the axle near the collar the outer set-screws will bear against the arms at the ends, the difference in the lengths of the set-screws corresponding to the taper of the arms. The front set-screws 15 are arranged in the same manner, the outer ends of the set-screws on'the middle sets being level and the outer ends of the set-screws on the outer sets being level; but the outer set-screws project beyond the inner ones to correspond to the taper of the arms of the axle.

The difference in the lengths of the outer and inner set-screws is clearly illustrated in Fig. 2.

In using the gage the inner sets 11 are adjusted so that the set-screws on the sets will fit against the collars 18 of the axle 17 and upon the inner surface of the arms 19 of the axle, and the outer sets are adjusted so that their set-screws will impinge upon the arms 19 of the axle on the outer ends of the arms. The set-screws are adjusted in the manner described, so that the appropriate set-screws will fit the bottom and front and rear sides of the axle and bear upon the arms when the axle is properly turned, and if there is any defect in the axle it will be indicated by the sets. When the sets are removed from the bar 10, the bar may be used as a rule or as a straight-edge.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- An axle-gage comprising a bar and a series of sets held to slide on the bar, the sets having equidistant set-screws projecting from three sides and a thumb-screw inthe fourth side adapted to impinge on the bar, substantially as described.
