AXLE-GAGE.

SPECIFICATION forming part of Letters Patent No. 337,606, dated March 9, 1886.

Application led December 5, 1885. Serial No. 184,816. (No model.)

.To all whom it may concern:

Be it known that I, HECTOR MCQUARRY, of Allandale, in the Province of Ontario and Dominion of Canada, have invented a new and Improved Axle-Gage, of which the following is a full, clear, and exact description.

The object of my invention is to provide certain new and useful improvements in the axlegage for which United States Letters Patent No. 308,685 were issued to me on the 2d day of December, 1884:.

This invention relates to gages employed to determine the bend to be given to an axle, so that the lower supportingspokes ofthe dished wheel turning thereon will be always plumb, and that said wheel may have the required gather.7

The invention consists in the construction and combination ofthe various parts of the axle-gage, as will be hereinafter described and claimed.

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

Figure l is a plan View of my improved axle-gage. Fig. 2 is a longitudinal elevation of the same. Fig. 3 is a detail plan view of the dish-rule. Fig. 4 is a cross-sectional view on the line v zr, Fig. 2.

The dish of a Wheel being measured by the ratio of the outward displacement of the outer ends of the spokes beyond theinner ends to the length of said spokes, the downward Vbend given to the axle at the end to cause the lower' spokes to be always plumb, said bend being equal to the dish,is measured in the same terms.

In the drawings, A represents the body or base of the gage,which is provided at one end with the upwardly-projecting head B, having the slot B formed through it lengthwise. In said slot the hub C2 of a bracket-arm, C, is pivoted to swing by the pivot C', and said bracket-arn1 is curved and extended downward, and is provided on its lower end with a fork, D, between the prongs of which the forked piece E is pivoted, having V-shaped notches in the ends ot' its prongs F, to adapt said ends to fit on an axle and hold the piece E parallel with the same. On the other end of the bar'A the sliding piece G is held bya set- Screw, H, and is provided with the downwardly-projeeting part J,n0tched in'its lower end to fit the axle.

On the top of the bar A the plate K is held, which is termed the dish-rule, and is provided with the longitudinal central line, a, vertically in line with the pivot C and the notched end of J. At each side of the. line a the parallel lines d are provided, and marked to indicate their respective distances from the line a.

In this case the lines are one-eighthv of an inch apart, and their distances measured down to form stops, which can strike the side edges of the bar A.

rlhe spoke-rule L is divided at the swinging end into inches and fractions thereof, and the divisions are numbered to denote their respect-ive distances in inches from the center of the pivot O. l

On the bracket-arm the pointer O is formed nearly vertically in line with the piece E, and which projects over the spoke-rule, having the mark W, to which the pointer O normally points.' The index end of the pointer swings under a hook-arm, P, extending over the bar A, and provided with gage-marks h h, with which a stud or projection, R, on the pointer can register, and which serve to indicate the forward gather of the axle-arm.

The clamp S, having the screw T, serves to lock the swinging end of the spoke-rule L in place.

The operation is as follows: The gage is placed on a perfectly-straight rod, and the spoke-rule L is placed with its divided edge in coincidence with'the central line, a, of the dish-rule and locked in place by the clamppiece S, holding its curved end piece, M. If the instrument is in adjustment, the index O will point to the mark W,and the button, pin, or stud R will coincide with the central mark,

IOO

h. The gage is then adjusted for the dish of the wheelto be mounted on the axle. If, for example, the wheel has one-half an inch dish in twentytwo inches of length ofspoke, the spoke-rule is moved outward until the mark twenty-two thereon is fairl7 even with the line on the dish-rule marked as being one-halt' an inch from the central line, a, in this case No. 4, and then the spoke-rule is locked in this position. Then the gage is placed on the side otthe axle whose bend is to be determined, the inner notched prong, F, resting againstthe axle-collar, and said inner prong being nearly vertically in line with the pivot C,the bar Ais supported on and above the main straight part ofthe axle and parallel therewith andthe notched piece E rests on and is parallel with the axle-arm. If the pointer does not point to the mark XV on the spoke-rule, the axle must be heated and set in the usual manner until when the gage is placed thereon the index or pointer O points to the mark W.

To obtain the required gather the axle is set, so that when the gage is placed thereon the stud R on the pointer O will coincide with the outside gather-mark, h.

As the gage isa double-scale gage, it can be placed on the forward or rear side of the axle to set for dish and on the bottom or top to set for gather, which is very advantageous when only one side of the axle is approachable.

Having thus described my invention, what I claim,and desire to secure by Letters Patent, 1s-

l. In an axle-gage, the combination, with the bar A, ot' the slotted head B on the same, and the bracket-arm C, pivoted in said head and provided with the pointer O, extending over the barA, substantially as herein shown and described.

2. In an axle gage, the combination, with the bar A, of the slotted head B, the bracketarin C, pivoted in the saine, which arm C has the pointer O formed on one end and has the 4 other end forked, and of the forked notched piece E, pivoted in the forked end of the arm C, su bstantially as herein shown and described.

8. In an axle gage, the combination, with the bar A, of the slotted head B, the bracket- 5o the bar A, and provided with a pointerswing- 6o ing above the spoke-rule, substantially as herein shown and described.

5. In an axle gage, the combination, with the bar A, of the dish-rule K on the same, the curved arm I?, extending over the top ol' 6 the spoke-rule and provided with the marks li, the spoke-rule L, pivoted to swing over the dish-rule, and ot' the bracket-arm C, pivoted on one end of the bar A and provided with the pointer O, havingthe projection or pin It, 7o

adjacent to the arm I?, substantially as herein shown and described.

6. In an axle-gage, the combination, with the base or body and the spoke-rule, of the dish-ruleK, having a longitudinal central line, 7 a, and longitudinal parallel lines d d at both sides ofthe said central line, substantially as set forth.
