BELT-SHIFTING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 399,501, dated March 12, 1889.

Application filed November 5, 1838. serial No. 290,011. (No model.)

To all whom it may concern:

Be it known that I, JOHN .l'. DALEY, a citi- /ien of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful improvements in Belt-Shifting Mech anism; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to belt -shifting mechanism.

The object is to produce a belt-shifter which may be used upon any machine, but more particularly, in this instance, upon ironing-machines, by means of which the belt may be shifted to start, reverse, and stop the same in a simple and eiii'ective manner and with the use of but a small amount of physical force, which may be operated by the foot alone, and which shall be simple of construction, efiiciei'it and durable in use, and inexpensive of production.

lYith these objects in view the invention resides in a bcltshitter coi'isisting, essentially, of stationary belt-rods mounted upon movable shifting-rods and means for operating the same, whereby the said rods may be moved from one set of pulleys to another, and thus start, reverse, and stop the machine, as desired; furthermore, in the various novel detail. of CODStl'LlGilOIl, as will be hereinafter fully described in the specificatioi'i, illustrated in thodrawings, and pointed out in the claims.

In the accon'ipanying drawings, forming part of this specification, and in which like letters of reference indicate corresponding parts, I have illustrated one form of device embodying the essential features of my invention, although the same maybe cariied into effect in other ways without in the least departing from the spirit thereof; and in these drawings Figure 1 is a perspective view of an ironing-machii'le showing my improvement attached thereto. Fig. 2 is an enlarged side elevation of the shifting mechanism and a shaft with pulleys mounted thereon, showing the manner in which my device is operated. Fig. 3 is'a side elevation showing a pulley with a belt-rod surrounding the same. Fig. l. is a detail view of the bracket to which the belt-rods are secured.

In the class of machines to which this device is to be attached it is necessary to have a beltshifter which may be operated with readiness and ease to start, reverse, and stop the same with certainty and dispatch, so that; the operator may be enabled to operate the mechanism by the use of the foot alone.

By referring to the aocom pan ying drawings it will be seen how this is readily carried into effect, and in these drawings A designates an ironirig-machine, which may be of any construction, and as this forms no part of the invention, but only serves to illustrate clearly the manner of carrying my invention into effect, I will not describe it minutely, but only such parts thereof as are necessary to give a clear understanding of the case.

The frame 1 of this machine may be constructed in any manner and of any material that will combine durability, facility of manufacture, and cheapness. Upon the uprights of the machine and at each end is secured across-piece, 3, in which are mounted movable shifting-rods at for shifting the belt from one set of pulleys to another. These shifting-rods carry stationary collars 5, connected by a cross-piece 6, to which is pivoted an arm, 7, which connects with a vertical rod, 8,pivotally secured to a weighted lever, fl, operated. by a connecting-arm, 10, one end of which is pivoted to the said arm and the other end to a foot-treadle, l 1. This foot-treadle mounted upon a rod, 12, secured in two standards, 13 and ll, upon a plate, 15, secured to the floor.

Upon the outer end of each of the movable shiftingrods lis mounted a bracket, 16, held in place upon the rods by means of bolts 17. These brackets carry the belta'ods consisting of a center rod, 18, which extends entirely around the pulley, and two half-rods, 19 and 20, all three of the rods being secured to the cross-piece 21. This cross-piece, as seen, preferably placed above the pulley and the half-rods ill) and 20 are secured to it, the halfrod 19 extending from the said cross-piece over the pulley on one side and the half-rod 20 over the pulley on the other side, and between these rods the belts run. The object of this cross-piece is to admit of all of the belt-rods being moved at one and the same time when the foot-treadle is operated.

Having now described the different parts of my invention, I will proceed to show the manner in which it operates.

The shaft 22 of the machine is provided with four pulleys, the two center ones, 23 and 24, being loose, and the outer ones, 25 and 26, tight. It is to be understood, also, that two belts are to be used, one being straight and the other crossed, so as to give a reverse motion. Now, when it is desired to reverse the motion of the machine, it is only necessary to press down the foot-treadle, which, through the medium of the arms and lever before referred to, will operate the two sliding rods, and thus draw the belts from the position occupied in Fig. 1 to that shown in Fig. 2, which will immediately reverse the machine, and by pressing the foot-treadle in the opposite direction the motion will again be reversed; but when the machine is to be stopped entirely the treadle is brought to a horizontal position, when the belts will be thrown upon two center pulleys, thereby stopping the machine. In order to regulate the pressure required to operate the shifters, a weight is secured upon the outer end of the lever 9, and is capable of being movedin or out, so as to make the throw of the treadle either heavy or light, the said weighted lever being supported by means of an upright, 31, which may be either secured to the frame of the machine or to the floor. In order to prevent the movable shifting-rods being thrown too far to one side, two stops, 27 and 28, are secured thereon at such a point upon the said rods that when the belt is shifted they will abut against the upright 2 of the frame, and thus prevent the belt being thrown off the pulley.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a belt-shifting device, of two movable rods mounted in crosspieces of the supporting-frame, the outer portions of said rods carrying the belt-rods and the inner portions united by collars 5, connected with a lever for operating the rods, whereby the same may be moved in the direction necessary either to start, reverse, or stop the machine, substantially as specified.

2. The combination, with the movable rods mounted in cross-pieces upon the end of the frame, of brackets 16, secured thereto and carrying the belt-rods consisting of a center rod encircling the pulley and two half-rods e1:- tending half-way around the pulleys, substantially as described. 7

3. The combination, with the cross-piece having collars 5 mounted upon the shiftingrods, of an arm, 7, connected with said crosspiece, the outer end of the arm being pivoted to a vertical rod, 8, secured to a weighted lever, 9, upon a standard, 31, secured to the frame, substantially as specified.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
