AXLE-GAG E.

SPECIFICATION forming part of Letters Patent No. 309,984, dated December 30. 1884.

Application illvtl May28, 1884.

To all 1071,0722, it may concern.-

Be it known that I, Burris ANDREW Sine SON, of Ferndale, in the county of Humboldt and State of California, have invented a new i and Improved Axle-Gage. of which the following is a full, clear, and exact description.

The object of my invention is to provide for wagon and carriage manufacturers and repairers a gage for accurately measuring the set and gather of a wagon wheel, and for use in indicating accurately the exact set and gather for iron and steel axles.

My invention consists in the construction and combination of parts, as will be hereinafter fully described and claimed.

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

Figure 1 is a front elevation of my improvec axle-gage, with parts broken out to bring it within the compass of the drawing. Fig. 2 is a rear elevation. Fig. 3 is a longitudinal section. Fig. 4 is a transverse sect-ion taken on line a: x in Fig. 1; and Fig. 5 shows the complete gage, on a reduced scale, applied to a wagon-axle.

The body of the gage is formed of two bars, A B, connected together by a pivot, a. A tapered arm, 0, which is a prolongation of the bar B, extends from the pivot a over the bar A, and is provided with a central longitudinal line, 7), extending from the pivot a to the end of arm, and representing the face-line of the spoke of wheel. Transverse radius-lines c, crossing the face of spoke-line b at right angles and placed an inch apart, represent the semi-diameter of the wheels whose axles are to be set by the gage. The transverse radius lines 0 are numbered to correspond with the number of inches they are removed from the pivot a, the said pivot (0 representing the center of wheel. A slide, D, on the bar A carries a loop, D, through which the arm G ex This loop is graduated on its outer A bow-spring,

surface into parts of an inch.

d, secured to the slide D, engages rounded projections e on the back of the bar A, and holds the slide D in any one of aseries of positions varying by one inch, and corresponding with the graduations on the arm 0. The

(X0 model.)

bars A B are provided with universal clamps E E E, which consist of two curved arms,f, pivoted together on abolt, and having their free ends bent away from the bars A B, and

parallel with each other, forming fingers f. The curved arms f are connected by links h with bolts 13. The bolts 9 i are provided with wing-nuts for convenience in operation, and the said bolts gt of the clamp Eextend through a central longitudinal slot in the bar A, near its free end. In a similar manner the bolts r z of the clamp E extend through a central longitudinal slot in the bar B, and the bolt 5 of the clamp E extends through a hole in the bar B, while bolt 71 of the said clamp passes through a central longitudinal slot in the bar.

In use the clamp E is drawn together by pushing the bolt 1; toward the pivotal bolt 9, so as to bring the fingers f against the armFof the axle G, near the collar of the axle, as shown in Figs. 3 and 5. The clamp E is then adjusted to suit the length of the axle arm F, when the bolt 1 is tightened. The armsf are then drawn together and fastened by tightening the bolt 1' In a similar manner the clamp E is brought into engagement with the arnr F of the axle G. The slide D is now moved on the bar A to bring the edge of the loop D opposite the transverse line representing the radius of the wheel belonging to the axle to, be gaged. The axle is now heated, then bent in the usual way and the gage applied to it, and then the axle is bent until the line b on the arm 0 is opposite the graduation on the loop D, representing the required set or gather. For the set the gage is applied to either the front or hind side of the axle, and for the gather to either the top or bottom of the axle.

My improved gage is adapted to axles of all shapes and sizes, and is used without regard to the length or taper of the arms. The universal clamps move equally in both directions, and therefore bring the central longitudinal line, Z), and the central longitudinal slots of the gage over the center of the axle. The pivot a represents the center of wheel, (or hub,) and the tapered arm 0 represents the spoke, or two spokes laid face sides together, forming the line b, and serves to represent the face of the spoke for either right or left hand setting.

I am aware that axle gages have been provided with depending clamp-bars operated by toggle-joints and set-screws working through slots in the gage-bars; also that the gage-bars have been pivoted together, with one bar ex has been secured to one barto guide the other bar; and I do not desire to claim, broadly, such construction as of my invention.

Having thus described my invention, What I claim as new, and desire to secure byLetters i Patent, is

1. In an axle-gage, the combination of the bars A B, pivoted at a, and provided with adjustable clamps at the free ends of the bars,

the bar B being provided with a graduated 20 extension, 0, and the bar A having project ions c, with the slide D, provided with a springcatch for engaging the projections e, substantial] y as set forth.

2. In an axle-gage of the character described. the combination of the bar A and the bar B, pivoted at a to said bar, and formed with the extension 0, said extension provided with a scale consisting of the longitudinal line 1), extending from the pivot a to the free end thereof, and transverse graduations 0, with the slide D, embracing the bar A and extension 0, and provided with a graduated loop, D, substantially as set forth.
