IMPROVEMENT IN AXLE SETS A-ND GAGES.

Specification forming part of Letters Patent No. 179,264, dated June 27, 1876; application filed April 29, 1876;

To all whom it may concern:

Be it known that I,'WILLIAM O. CARLTON, of Boise City, Ada county, Idaho Territory, have made certain new and useful Improvements in Axle Sets and Gages,.of which the following is a specification:

This invention relates to that class of devices and apparatus designed for the setting ot'axles, the gaging of the dish of the wheels, and also the gaging and adjusting of the gather thereof, all of the said purposes being accom plished by means of a single apparatus or instrument, constructed, arranged, and applied as will hereinafter be fully described and pointed out.

In the drawings, which form an important part of this specification, Figure 1 represents an elevation of an apparatus in which is fully embodied my invention. Fig. 2 is a partial elevation in reverse, showing the method of gaging the dish of the wheel; and Fig. 3 is an elevation, showing the application of the apparatus to the axle, and the method of adjusting and setting the spindle of the axle.

Similar letters of reference found in the various figures of the drawings will locate and point out corresponding parts.

To all who are familiar with the construction of wheeled vehicles, such as carriages, wagons, &c., the difliculties attendant upon the setting of the axles and wheels are well known, as also the diificulties of getting and adjusting the gather of the wheels. Many devices, ways, and means have been devised for these purposes, but thus tar without practically obviating the troubles met with.

Perfect accuracy is necessary to insure the proper running of the vehicle, and a device which shallabsolutcly accomplish the purposes stated is a great desideratum.

The object of the present invention is to provide a single instrument, of simple construction, which shall be quickly and easily applied to the wheels and axles, and at once, and with perfect and absolute accuracy, determine the dish of the wheel, the taper of the axle-spindle, the setting-point to which the axle-spindles are to be adjusted, also the gather of the wheels when such is desired.

It may be remarked that this present invention consists, in part, of oertainimprovements upon the axle set and gage for which I filed an application for Letters Patent on January 22, 1876.

A is a metal bar, of suitable thickness and width, so that it will not bend, and, in a fullsized apparatus, is usually about six feet in length. At the left-hand end it is provided with a standard, L, usually about four and a half inches long, which slides longitudinally thereon, and is set at any desired point by means of athumb-screw, M. At its base it is provided with arms N, the curved shape of which conforms to the circular shape of the ordinary axle.

0n the right-hand end of this bar A it is let into another flat iron bar, B, of similar shape, and is provided with a joint, 0, and pin D, forming a pivot, on which the two bars move. This bar B extends to about the center of the bar A in its rear, as shown in dotted lines in Figs. 1 and 3, and in Fig. 2 by a reverse elevation of the same. It is, at its, left-hand end, provided with. a short arm, E, which is pivoted thereon by means ofa pin, F. Shown best in Fig. 2.) This short arm E is provided with a longitudinal slot, G, in which a pin, H, plays, this pin being provided with a suitable screwthread and thumb-nut, I, which passes through the slot, and is screwed into the iron bar A. This serves to clamp the short bar E, in any desired position, andthus holding the bar B in place when it is once set.

Attached to the bar B, and sliding longitudinally thereon, is a vertical rule, J, which is adjusted and retained in any desired position by a flat spring, as shown 5 or it may be provided with a set-screw, if preferred.

The bar B, near its righthand end, has a tapering standard, K, which projects therefrom directly over the center line of pivot O and pin D. It corresponds in length with that of standard L upon the bar A, minus the curved arms. The bar B is extended to the right'of the standard K about one foot, and upon this extension is placed a sliding tapertaking device, as shown in Figs. 1 and 3. This extension of the bar B has out upon its face, at right angles to its length, a scale of inches, which indicates the length of the axledotted lines sin Fig. 1.

arm the other parts of the device are secured and manipulated. d is a sliding gage, resting against the base of the slide a, which prevents it from tilting. It has a longitudinal slot, 6, through which a setscrew, e, is passed, and enters a screw-hole in the arm 0, the gage sliding thereon from left to right, or vice versa, as the case may be, and when in the desired position the set-screw e secures it immovably in place. At the right-hand end of this sliding gage it is provided with an arm, 01, which is turned at right angles thereto, as shown.

Pivoted at the base of the depending arm 0 by means of pin 7c is a rocking gage f. At its apex it is provided with an arm, g, projecting to the left, and having a slot, h, centrally therein, through which a se't screw, 13, passes, and enters a screw-hole in the arm 0, by means of which it is secured firmly in any position where it may be set. At the base of this gage f, and projecting to the right, is an arm, in, which has at its extreme right-hand end a short arm, n, depending therefrom at right angles, as shown. When the gage f is so set that its vertical position is on a line and corresponds with the vertical'position of the de-.

pending arm 0, the point a of its lower arm m will rest at the point indicated by the dotted lines m x, which dotted lines also indicate the base-line, upon which the standards or arms K and L rest when the apparatus isinits normal position, as shown in Fig. 1. This portion of the apparatus is for taking the true taper of the axle-spindle, audit may, for convenience sake, be removed from the bar 13 for that purpose. In the process of taking the taper of the spindle it is slipped in between the arm 0 and arm d of the sliding gage d, the top part of the gage resting on the top surface of the spindle. The arm d! is then pushed to the left until it presses the spindle against the arm 0. It will be understood that this portion of the gaging is taken from the spindle close to the shoulder, where its diameter is the greatest. The sliding gage is then secured'in its position by the setscrew b. This gaging of the spindle is plainlyindicated by the The apparatus is next moved out to the point of, or smallest diameter of, the spindle, and the rocking ga ge f moved to the right until the spindle is pressed against the arm d of gage d, as indicated by dotted lines o in Fig. 1. The gagefis then fastened in place by the set-screw The apparatus is then removed from the spindle and replaced in position on the bar B, as before described. It will thus be seen that the arm d, arm 0, and rocking gage f practically become a double calipering device, the point of the arm 'n at the base, by its variations from the dotted base-line w 40, indicating one-half of the truetaper of the spindle from base to point.

After the taper of the spindle has been taken, as described, and the gages locked into position, the device is reattached to the bar B. The dish of the wheel is then taken, as is illustrated in-Fig. 2; or this part of the opera-' tion may be accomplished before attaching the taper-taking device to the bar. 0 represents the telly of the wheel P, the spokes R, the axlehub, and S the axle-shaft; these parts being well understood, no detailed description is herewith called for. The entire apparatus is then placed against the rim of the wheel, the standard K at the right hand resting against the tire. The set-screw I, which secures bar 13, is then loosened, and the said bar moved up until the sliding rule strikes against the spoke of the wheel over the center of the hub, at which point the bar B is secured by the setscrew 1.

The apparatus is now set and ready for application to the setting of the axle-spindle for the dish, which operation is plainly shown in Fig.3.

T represents the body of the axle-shaft. In the drawing it is shown as straight and cylindrical; but it may be arched and square, or of any shape that may be called for. t t are the axle-shoulders, and V V are the usual tapering spindles. cally below the axle, the standard or arm K resting on the spindle V, close to the shoulder t. The sliding standard or arm L is then moved and set into a similar position upon the opposite or left-hand spindle V, and close to the shoulder 25. The taper-taking device is then adjusted upon the extension of the arm B until its lower point it rests directly over the point or small end of the spindle. This gives the point to which the spindle is to be set, and it is then bent, by the usual process, until the point a rests upon it, when it is f nally and accurately adjusted or set. The apparatus is then removed and reversed, and the left-hand axle-spindle is set in the same manner.

The adjusting of the axles to the gather of the wheels is accomplished as follows: The sliding rule being set opposite the center of the hub of the wheel, as previously described, the set-screw securing arm B is loosened, and moved up or down until the scale on the sliding rule J indicates, by the base-line of the bar A, one-fourth of the distance of the gather desired. The apparatus is then applied horizontally to the front side of the spindles, in the same manner asin the process of setting the spindles .for the dish of the wheel. The points of the spindles are then bent until the point a of the taper-taking arm is touched, which operation accurately adjusts the gather to be given to the wheels.

Having thus fully described my invention, what I claim as new and useful and as my invention is- The instrument is placed vertia 1. In an apparatus for gaging and setting axles, the combination of the bar A, provided with adjustable standard L, bar B; provided with fixed'standard K, and adjustable slotted arm E, the two pivoted together by pin D,

and the. adjustable taper-taking device, eonand rotating gage f, having adjusting-arm g at its apex, and indicating-arm n at its base, the Whole arranged for taking the diameter of the axlespindle at both base and point, indi-- eating the taper thereof, as and for the purposes as herein shown and set forth.

In testimony whereof I have hereunto set my hand this 2Sth day of April, A. D. 1876.
