SPECIFICATION forming part of Letters Patent No. 759,766, dated. May 10, 1904.

Application filed August 6, 1903. $erial No. 168,409. (No model.)

.To all whom it may concern.-

Beit known that I, GEORGE H. STANT, a citizen of the United States, residing at Connorsville, in the county of Fayette and State of 111- diana, have invented new and useful Improvements in Axle-Setters; and I do declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a partof this specification.

This invention relates to machines for setting axles of vehicles, straightening and bending metal bars, and for similar purposes, principally for use in blacksmith-shops and machine-shops, the invention having reference more particularly to the die-heads in which the axles or other articles are to be held and operated upon andv to the power mechanism therefor.

The object of the invention more particularly is to provide a cheap and economical power axle-setter in which the work may be directly under the eye of the operator and which may also be constructed so as to be operated by hand-power with the least expenditure of manual force.

A further object is to provide a machine or device of this character which my be controlled with the greatest degree of precision.

A still further object is to provide an axlesetter of this character with the most convenient form of means for operation, so as to be adapted to the operators working position, and which may be useful for many other purposes besides that of setting axles.

The invention consists in the novel parts comprised in the machine and in the novel and useful combination and arrangement of parts, as hereinafter particularly described and claimed.

Referring to the drawings, in which similar reference characters designate like parts, Figure 1 represents a side elevation of the machine set up in operative position and in which is a section of an axle; Fig. 2, a front elevation of the machine; Fig. 3, a central vertical sectional view taken in a plane parallel with the plane of motion of the operating-lever thereof; Fig. 4, a horizontal sectional view in the plane of the pivot which connects the two die-heads; Fig. 5, a top plan view showing an axle end in the machine; Fig. 6, a top plan view ofthe movable diehead; Fig. 7, a top plan view of the stationary die-head; Fig. 8, a side elevation of the machine provided with an adjustable pivot for the movable head and power-gearing in lieu of the lever for operating the movable head; Fig. 9, a front elevation of the machine shown in Fig. 1; Fig. 10, a horizontal sectional view in the plane of the pivot of the movable head; Fig. 11, a fragmentary front elevation of the heads and gearing for the adjustable pivot, the housing of the gearing being in section; Fig. 12, ahorizontal sectional view in the plane of the eccentric, and Fig. 13 a fragmentary side elevation of the heads and sectional view of parts of the gearing connected with the adj ustable pivot.

In a practical embodiment of the invention two opposing die-heads A and B are employed, which coiiperate by means of suitable appliances, one head being provided at its inner face with a pair of dies 0 and C, separated somewhat from each other, and the other head being provided with a die 1'), disposed centrally at the inner face of the head, so that it may operate in a plane intermcdiately of the other two dies in the opposing head. These heads are provided with particularly powerful operating appliances, so that the force applied to them may be graduated nicely in order to avoid the application of excessive power and consequent distortion of the work.

Specifically, the head A is stationary and is attached integrally to a column composed of a main member a and two side members 7) and. 6', extending forwardly as flanges from the front edges of the member (1 The column is designed to extend from the shop-floor upwardly beyond the tops of work-benches, so that the heads will be nearly as high as the workmans shoulders when standing. In the lower end of the column is a shaft (3, journaled in the side members Z) 7/. The column is to be supported vertically by any suitable means such as the bracket a, having the bolthole j, shown herein, which is attached to the upper portion of the column. The head A may be provided with vertical strengthening-ribs g g at the back thereof.

The inner or opposing faces of the die-heads A B have the dies 0 G and D suitably connected therewith. As shown herein, the stationary head A has two vertical grooves It and 7t, and the movable head B has a like groove 2', the grooves having bottoms broader than their top openings, and the dies are shaped so as to fit neatly into the grooves, and they project suitable distances toward the opposite heads, having rounded faces. The dies are removable and interchangeable, and sets of different thicknesses are employed, so as to accommodate either thick or thin pieces of work to be acted upon.

At the base of the head A where it is joined to the top of the column the column is provided with a pair of pivoting ears E and E, these being reinforced by means of projections j extending across the side member-s Z) 5, and it is so designed that these may be situated at about the top of the supports, as k Z of the column, so that the pivoted point may be at a suitable height above the floor. A pivot-pin F is mounted in the ears E E and fixed in any suitable manner or rendered adjustable, as hereinafter described.

As a means for operating the movable head an eccentric G or cam is secured to the rotative shaft (Z between the side members 6 I), the shaft extending beyond one of said side members. An operating-lever I is suitably secured to the shaft (Z in the hand-power machines, and it extends upwardly to the top of the machine or about the plane of the dieheads, so that the lever is about the same length as the machine, and being pivoted at the bottom of the machine affords ample leverage.

The movable head B is supported and directly operated by an arm m, having a strengthening-rib 12 all being integral, a strong pivoted body H being provided at the top of the arm where it is joined to the base of the head, the body H being mounted rotatively on the pin F. The arm extends to the eccentric G and is engaged thereby, the arm being adapted to operate between the side members 61). It will be seen that the leverage of the arm m is also very great in addition to that of the lever I, so that a very great degree of force may be applied to the head B with little manual effort, and therefore the force applied may be easily controlled.

In the geared power-machine the side members Z) 7) are provided with slots 1), Fig. 13, extending through the bodies of the projections y'j, and boxes J J are fitted movably in the slots, each box having a spring K arranged in the slot and pressing the box forwardly. Each box has an aperture 9 to receive an end of the pivot-pin F, which is directly supported by the boxes and supports the head B and its arm 12?. The cars E E have screw-threaded holes 2', in which are fitted screws L L, having their outer portions formed as spindles in which are splineways s. A yoke composed of two parallel arms M and M and an open gear-head N is secured rigidly to the side members 6 Z), the arms being fitted against the faces of the projections j j and extending beyond the ears EE', the head N extending across the front of the machine beyond the body H. The spindles of the screws L L are mounted rotatively in the head N, and the screw ends enter the ears and engage the boxes J J, so that in operation the screws also move longitudinally in the head N. In the opening 4; of the head N are two gear-wheels O and O on the spindles of the screws L L, the wheels having each a spline t fitting in the splineway s of the spindle, so that while the wheels may cause the screws to rotate the latter may also move endwise through the wheels. A shaft P is mounted rotatively in the head N, and a pinion Q is secured to the shaft in the opening o and engages both of the wheels O and O, the shaft being provided with a hand-wheel R at the front of the head N for operating the gearing and the pin F.

In the power-machine the column a is provided at its rear lower portion with a housing a, in which a counter-shaft S is rotatively journaled and provided with a pinion T, which engages a gear-wheel U, that is secured to the shaft (Z, (in lieu of the lever I.) A fly-wheel V is secured to one end of the shaft S, and on the opposite end thereof a pair of pulleys IN WV are mounted, one tight and the other loose, for applying belt-power.

In practical use the hand-power machine may be operated in the following manner: The lever I should be held by the operator while the work, as an axle m, is adjusted between the dies of the opposingheadsA and B. The lever may then be manipulated and the work shaped according to design in full view of the operator. By reference to Fig. 5 it will be seen that the die D, applied to the axle midway between the two dies C and C, would cause the axle to be flexed, and thus by proper readjustments of the axle it may be easily curved or be offset, or distorted pieces may be straightened in a convenient manner. The geared power-machine, connected by means of a belt to a suitable source of power, may be set in motion, the eccentric G of course being moved about its shaft, and while manipulating the hand-wheelR, so as to suitably adjust the die D, the work may be placed between the dies and set according to requirements.

Having thus described the invention, what I claim as new is 1. In an axle-setter, the combination of a column having a die-head at the top thereof and provided with slots extending horizontally IIO below the head, a pair of boxes mounted in the slots, springs bearing against the boxes, a pivot-pin mounted in the boxes, an arm having a die-head at the top thereof and mounted on the pivotpin, a pair of operating-screws suitably supported and engaging the boxes, a pair of gear-wheels mounted on the screws for operating the same, a pinion mounted between the gear-wheels and engaging the same, a hand-wheel operatively connected with the pinion, and means connected with the column and cooperating with the arm for the operation thereof.

2. In an axle-setter, the combination of a column having a die-head at the top thereof, an arm having a die-head at the top thereof and pivoted to the column, a housing attached to the column, a shaft mounted in the column in a plane below the housing, an eccentric attached to the shaft, a gear-wheel also attached to the shaft, a counter-shaft mounted in the housing, a pinion secured to the counter-shaft in engagement with the gear-wheel, and a driving-pulley attached to the counter-shaft.

3. In an axle-setter, the combination of the column having the slots therein, the die-head attached to the column, the boxes in the slots, the pivot-pin mounted in the boxes, the springs engaging the boxes, the arm mounted on the pivot-pin, the die-head attached to the arm, the yoke attached to the column and having the screws mounted therein in engagement with the boxes, the gear-wheels mounted in the yoke on the screws, the pinion mounted in the yoke in engagement with the gearwheels, the hand-wheel connected with the pinion, the shaft mounted in the column, the eccentric mounted on the shaft and cooperating with the arm, the gear-wheel attached to the shaft, the counter-shaft mounted in the column, the pinion attached to the countershaft in engagement with the gear-wheel on the shaft supporting the eccentric, the pair of pulleys mounted on the counter-shaft, and the fly-Wheel attached to the counter-shaft, substantially as set forth.

4. In an axle-setter, the combination of a column consisting of a main member and two parallel side members extending from the sides of the main member beyond the front and from the bottom to the top thereof, said side members having the reinforcing-plates at the top thereof terminating in cars, said column having a die head provided with grooves in the front thereof, and the dies seated in said grooves, with a movable arm pivoted between said ears, and the eccentric mounted between said side members of said column, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
