BENJAMIN H. HADLEY, OF PROVIDENCE, RHODE ISLAND.

BELT-SHIPPER.

SPECIFICATION forming part of Letters Patent No. 234,563, dated November 16, 1880.

Application filed September 23, 1880.

To all whom it may concern Be it known that I, BENJAMIN H. HADLEY, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Belt-Shippers; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawin gs, forming part of this specification.

This invention has reference to an improvement in belt-shippers by means of which the belt for driving a machine can be moved from the loose to the tight pulley, and vice versa.

The object of the invention is to facilitate the moving of the belt from one pulley to the other and to hold the belt in the desired position.

The invention consists in the peculiar and novel arrangement of a crank secured to the end of a rod and connected with the shipper by a connecting-link, so that by turning the rod the shipper will be moved from one position to the other and locked in either position.

It further consists in the peculiar and novel construction of the bracket, bymeans of which the shipper mechanism can be supported in any desired position, all of which willbe more fully set forth hereinafter.

Figure l is a side view of my improved beltshipper, showing the improved hanger by which the same is supported,the rod bymeans of which it is operated, and the driving-pulleys. Fig. 2 is an end view of the same. Fig. 3 is an enlarged view, showing the crank operated by the suspended rod and its connection with the shipper-bar. Fig. 4 is an end view of a shipper, showing the adjustable hanger and the arrangement for operating the shipper directly or indirectly by means of beveled gears. Fig. 5 is a side view of the same. Fig. 6 is an enlarged view, showing the crank and connecting-link by which the shipper is operated.

In the drawings, (0 represents a plate socured to the ceiling or a girder. To this plate the bracket 1) is secured by means of bolts passing through slots made in the base of the bracket 1), which slots form a section of a circle, so that the bracket 1) can be adjusted on the plate a, and the face of the bracket, or, rather, the axis of the counter-shaft, can be (No model.)

I placed exactly parallel to the main drivingshaft to insure the true running of the belt.

0 is a bracket secured to the bracket 1), or it may be made in one piece with the same. In this bracket 0 is the eountershaft, on which the driving-pulley d and the loose and tight pulleys d and d are placed, and which are adjusted by adjusting the bracket on the plate a.

c is the shipper-rod, on which the belt-fork c e is secured. The rod is supported in the bracket 0, and is moved laterally by means of the rod f, extending down so as to be easily reached by the attendant. The lower end is provided with the handle f, by means of which the rod f is turned. The upper end of the rod f is supported in a sleeve forming part of the bracket g, and to the end of the rod f the crank his secured. The connecting-link i is pivotally connected with the crank it and with the rod 6, so that when the rod f is turned onehalf around the crank will describe a half-circle, and the shipper-rod is moved laterally a distance equalto the diameter of a circle described by the center of the pin or bolt connecting the link i with the crank h. A halfturn of the rod f will therefore move the belt from the loose to the tight pulley, and vice versa.

It is obvious that any width of belt can be moved from one pulley to the other by making the crank h of such length that the halfrevolution of the same will move the shipper the required distance. The throw ofthe crank being half the width of the pulley, the link i will extend out in a straight line beyond the crank when the belt is on one pulley, and will be brought over the crank when the belt is on the other pulley. In either of these positions the shipper will be locked and the belt prevented from running ofi the pulley, as the strain is in a straight line and has no tendency to turn the crank. By the turning of the rod fand crank it only can the shipper be moved.

To bring the handle f into the most convenient position for the operative the bracket 9 is made adjustable by means of the arm 70, which is secured to the plate l by a bolt,whioh can be moved in a segmental slot, so that the rod f may be placed on any desired angle.

In some machines it becomes desirable to operate the shipper mechanism at points distaut from the counter-shaft and the pulleys. In such cases I support my belt-shipper mechanism on a special hanger, as shown in Figs. 4, 5, and 6, and connect the link i with a sleeve to the extended shipper-rod. The hanger consists of a plate, a, on which the bracket 1) is secured or made in one piece. The bracket 1) has a circular face, to which the circular end of the bracket 0 is secured by a central bolt, so that the bracket 0 may be swung into the desired position and to allow for the adjustment of the operating mechanism on a line with the shipper-rod, the lower end of the bracket 0 is provided with ways or a true surface on which the sleeve 9 may be secured at any height to bring the sleeve 0 in the proper position to be secured to the shipperrod 0. The crank it is now secured to the rod f below the sleeve 9, and is connected with the shipper-rod by means of the link *6. As the link i, when the rod is turned, would come in contact with the rod f, and is thus pre vented from assuming the locked position, the link t'is curved, as shown in Fig. 6, and thus allows the crank it to describe a halfcircle and place the link and crank in a locked position in both directions.

It becomes at times necessary to operate the shipper mechanism from more than one place, and when such is the case I suspend from the brackets the rod m, Fig. 4, and secure to the same the frame a, (or this frame may be permanently secured in any other manner.) Through the frame at the rod f extends, the lower end being provided with the handle f. An additional handle, f extends laterally from the frame a in the desired direction, and is connected with the rod f by means of beveled gears, as is shown at the lower end of Fig. 4.

By means of this improved belt-shipping device a belt can be shipped from one pulley to the other more quickly than with the usual belt-shipper lever, much less room is required, and the belt is firmly held, as the device is self-locking in both directions.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A belt-shipper consisting of a shipper-rod provided with a belt-fork, an operating-rod provided with a handle by which it can be turned, a crank connected with the operatingrod, and by means of a link with the shipperrod, constructed to ship the belt from one pulley to the other by turning the operating-rod, as described.

2. The combination, with the rod f, of the adjustable sleeve g, constructed to support the rod in the desired position, as described.

3. The combination, with the counter-shaft and shipper device, of the plate a and bracket 0, constructed to support the counter-shaft and shipper and adjust the same, as described.

4. The combination, with the plate a and bracket I), of the adjustable bracket 0 and the sleeve 9, constructed to be secured to the bracket 0 and adjusted to the desired height, as described.

5. The combination, with the belt-shipper device, as described, of the rod f and one or more laterally-projecting operating-handles, f constructed to operate the shipper, as described.
