SPRING-SETTER.

SPECIFICATION forming part of Letters Patent No. 258,382, dated May 23, 1882,

' i Application filed AugustQO, 1881. (No model.)

,To all whom it may concern:

Be it known that we, JOHN CREAGAN and CHARLES D. TYLER, J r., of Cleveland, Guyahoga county, Ohio, have invented a new and useful Improvementin Sprin g-Setters, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof. l a

Figure 1, Sheet 1, is a plan view of our improvement, partly in section through the line an 00, Fig. 2. Fig. 2, Sheet 1, is a sectional side elevation of the same, taken through the line 3 3 ,Fig. 1. Fig. 3, Sheet 2, is a sectional end elevation of the same, taken through the line a z, Fig. 1.

Similar letters of reference indicate corresponding parts. i

The object of this invention is. to facilitate the settingof springs and promote convenience in adjusting the machine to give the desired form to the springs.

A represents the frame of the machine, to the end bars of which are attached the ends of two rods, B, which extend along the inner sides of the side bars of the said frame to serve as sup-.

ports and guides for the sliding plates 0 D. i The plates 0 D have upwardlyprojecting flanges upon their end edges and the end parts of their outer side edges to form beds for the adjustable fingers or bars E. The plates 0 D have lugs upon their ends, in the outer ends of which are a formed half-round notches or recesses to receive, fit, and slide upon the rods B. In the faces of the plates 0 D are formed grooves to receive the bars J, which extend across the,

space between the said plates 0 D to receive and support the spring to be bent or set. Upon each of the plates 0 D are laid a series of fingers or bars, E, placed side by side, and the ends of which project beyond the inner edges of the said plates 0 D. The fingers E are held down upon the plates 0 D by the cross-bars I, which are placed upon the said fingers E, and their ends are secured to the end flanges of the plates 0 D by the screw-bolts G. The fingersE are pressed together to further secure them in place by screws H,whieh pass through the end flanges of the plates 0 D and press against the side fingers, E. The fingers E can be conveniently released and adjusted to give any desired form to the springs by loosening the screws G H. The end parts of the outer edge of the forward plate, D, rest against the end parts of a curved spring, I, the middle part of which rests against and may be: secured to the forward cross-bar of the frame-A, so that the plate D will not encounter a rigid resistance when subjected to pressure in setting a spring. The fingers E upon the two plates 0 D are so arranged that the inner ends of each set offingers will describe the curve to be given to the spring, as shown in Fig. l.

i To the under side of the middle partofthe rear frame, 0, is attached, or upon it is formed,

a nut, K, the screw-thread of which fits into 6 the thread of the screw L, placed below the plates 0 D and swiveled in bearin gs attached to the frame A. The rear end of the screw L projects and revolves in bearings formed in or attached to the post M, which is strengthened in a vertical position by a rod, N, attached to "its upper part and to the upper part of a vertical frame, 0, attached to the rear end of the frame A. Upon the projecting rear part of the screw L are placed two fast pulleys, P, and 7 5 two loose pulleys, Q, the said loose pulleys being placed side by side and between the two fast pulleys P. The forward pair of pulleys,

P Q, is provided with a straight belt, R, and the rear pair of pulleys, Q P, is provided with a crossed belt, S. The belts R S pass around a long pulley, T, attached to the shaft U, which revolves in bearings formed in or attached to the upper ends of the post M and frame 0. The shaft U is designed to receive the drivingpower, which may be applied by means of a crank, a pulley and belt, or other suitable means.

V is a semi-cylindrical plate, which passes around the lower parts of the loose pulleys Q, 0 and has its end parts slotted transversely to receive the bolts W, that pass through longitudinal slots in the arms X, which project upward and have slots formedin their upper ends to receive the belts R S, so that both the belts can be shifted at one movement of the beltshipper, to bring both the belts upon the loose pulleys or to bring either of the belts upon a fastpulley, as may be required. The slots in the plate V and arms X allow the belt-shipper to be so adjusted that it'will move the belts the distance required. The middle part of the curved plate V is rigidly secured to a. bar, Y, the rear part of which slides in bearings in the post M and in the short post Z, placed at a little distance from the post M and connected with it by a tie-rod, a. The forward end of the sliding bar Y is pivoted to the upper end of a bar, I), the lower end of which is pivoted to the upper end of a short standard, 0, attached to the floor, the bed of the machine, or other suitable support.

To the lower end of the bar I) is attached, or with it is rigidly connected, the inner ends of two arms, 01 e, which project, the one outward and the other inward, at right angles with the said bar I), makingit a double anglelever. With this construction, by moving the outer end of the arm d downward the straight belt will be shifted to the forward fast pulley P and the crossed belt to the loose pulley Q, and the screw L will be turned forward to set the spring. When the outer end ofthe arm eis moved downward thecrossed belt will be shifted to the rearward fast pulley P and the straight belt to the loose pulley Q, and the screw will be turned back to release the spring. This construction allows separate treadles to be -of the lever g is pivoted the end of a rod, t,

which; slides in hearings in hangers j and 7c. The forward hanger, j, is attached to the frame A. The rear hanger, 7c, is attached to the-rear plate, 0, so as to be carried back and forth by the said plate in its movements. upon the guide-rods B.

To the rod 2', upon theoppositesides of the hanger k, are attached collars I m, in such positions that when the plate (J is carried forward by the movement of the screw L it will bring the hanger 7c in contact with the. forward collar, m, and operate the belt-shifter to move the belts R S upon the loose pulleys. In the same manner, when the plate 0 is completing its rearward movement, the hanger It comes in contact with the rear collar, 1, and shifts the:

belts to the loose pulleys. The belts are moved from {the loose pulleys to the fast pulleys to give motion to the screw L, to move the plate 0 in either direction by operating the double angle-lever b d e.

To the center finger, E, secured. to the plate D, is attached,or upon it is formed, a pointm, to enter a hole in the center of the springblank, to center the said blank, and thus insure its receiving the proper shape.

Having thus fully described our invention, weclaim as new and desire to secure by Letters Patent 1. The combination of the rods B,the grooved end flanged plates, 0 D, having notched end lugs, the adjustable bars E, held down by bars F, the bolts G, the screws H, and the bars J, as and for the purpose specified. 2. The combination, with the slide-bar Y, of the slotted lever g, the pivoted slide-rod 71, provided with collars Zm, and the hangers j k, one of which is attached to movable plate 0, as and for the purpose specified.

3. The combination, with the frame 0, of the nut K, the screw L, the two fast pulleys Q,

the straight belt R, the crossed. belts S, the long pulley T on drive-shaft U,- the slotted curved plate V, the slotted arms X, the pivoted slide-barY, and the bar b, pivoted to standard c and having arms dc, as and for the purpose specified.

4. In a spring-setter, the combination, with the sliding bar Y of the belt-shifter, of the double an gle-lever b d e, substantially as herein shown and described.
