S. 'STRUNZ. BELT SHIPPER. I

No. 244,336. Patented July 12,1881.

UNITED STATES PATENT Prion.

STEPHEN STRUNZ, OF PITTSBURG, PENNSYLVANIA.

BELT-SHIPPER.

SPECIFICATION forming part of Letters Patent No. 244,336, dated July 12, 1881.

Application filed June 20, 1881. (No model.) I

To all whom it may concern Be it known that I, STEPHEN STRUNZ, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Belt-Shippers, of which the following is a specification.

The object of this invention is to provide a belt-shipper which can be readily operated from any desired point, either adjacent to or at a considerable distance from the shipper also, to construct the shipper so that several belts can be shipped by the same mechanism, and also to construct the same so that when the belt is on the loose pulley the shaking of the machine can at no time cause the belt to be accidentally shipped from the loose to the fast pulley, so as to start the machine that is to be driven by belt-power.

To such end my invention consists in a shipper consisting of a jointed bar comprising three hinged sections, one end or outer'section being pivoted, and the other end or outer section being arranged to slide through guides and to ship the belt when moved endwise, a rope or cord being attached to one end of the central section of the jointed bar and passed over pulleys to some desired pointfrom which the shipper is to be operated, as hereinafter described.

In the drawings, Figure l is a side elevation of my invention with the drivin g-belt upon the loose pulley, and Fig. 2 is a like view with the belt upon the fast pulley.

My invention can be applied to all classes of machines where the belt is to be shipped from a fast to a loose pulley, or vice versa, although I especially intend it for presses Which occupy considerable space, and which therefore render it desirable for the operator to be able to ship the belt from some particular locality in the room where the apparatus is placed.

The shipper is composed of a jointed bar divided into three sections, A A A the two end sections thereof being connected with the central section by means of the hinges B B, the former of which is secured to the upper sides of one of the end sections and the central section, while the latter hinge has its leaves secured to the under sides of the center and the remaining end section of this jointed shipper-bar. The section A of the said jointed bar is pivoted atits outer end to a suitable bar or beam, 0, while the remaining end section, A, is arranged to pass through the straps or guides D, which can be secured either to the bar 0, or to any other suitable rigid support.

E indicates the loose pulley, and F the fast pulley, both of which are mounted upon a shaft, as usual.

The driving-belt G, which is to be shifted from one pulley to another, passes through a bail, H, which is secured to the sliding end section A, whereby an endwise movement of the said section will shift the belt. As a means for enabling a person to operate this belt-shipper from any desired locality, I connect a cord or rope, I, with the central section of the jointed bar at a point adjacent to its end that is hinged to the swinging end section of the jointed bar, and I extend this cord up over a suitable pulley, K, from which it can be carried over as many other pulleys as desired and then brought down to within convenient reach of the operator. Now, the belt being upon the outer loose pulley, E, the sections of the jointed bar will lie at a right line with their square ends abutting against each other, so as to practically constitute one solid bar. This absolutely prevents any accidental shifting of the belt when the bar is thus straightened out.

In order to ship the belt from the loose to the fast pulley, to transmit motion from the belt to the main shaft of the machine, the operator need only draw upon the end of the rope or cord that is within reach, whereby the tension on the same will elevate the connected ends of the sections A A of the jointed bar, raising the connected ends thereof laterally from the line of the sliding section A, whereby the latter will be drawn back, and thereby ship the belt. As soon, however, as the cord is released the weight of the central section and the pivoted swinging section will cause their connected ends to drop, whereby they will straighten out, and hence throw the sliding bar forward, the latter, in its movement, shipping the belt from the fast to the loose pulley.

It will be evident that the sliding section A of the jointed bar could be extended so as to carry another bail, and hence serve to shift a second belt passing through the same.

The device is extremely simple, not liable to get out of repair, and, owing to the few parts employed, it can be made at small cost.

Having thus described my invention, what I claim is- 1. A belt-shipper consisting of a jointed bar passing through the said guides, and provided with a bail passing around the belt, a central section, A, hinged to the sliding section at one end by a hinge on their top sides, and

hinged at its remaining end to a pivoted section, A, by a hinge on the under sides of said sections, the device being adapted to be operated by a rope or cord which is passed over a pulley, substantially as described.

In testimony whereof Ihavehereunto set my hand in the presence of two subscribing witnesses.
