SPECIFICATION forming part of Letters Patent No. 492,648, dated February 28, 1893. Application filed September 30, 1892. Serial No. 447,395. (No model.)

To all whom it may concern:

- Be it known that I, GUSTAVE P. WERN, of Brooklyn, in the county of .Kings and State of New York, have invented a new and Improved Oable-Support, of which the following is a full, clear, and exact description.

The invention relates to supports for cables such for instance, as are used for propelling cars of carrying devices employed for moving coal to furnaces of gas houses, or for other purposes.

The object of the invention is to provide a new and improved cable support, which is simple and durable in construction, very effective in operation, and arranged to swing out of position when struck by the car going in either direction, and to return automatically to its normal cable supporting position as soon as the car has passed.

The invention consists of an arm for supporting the cable and mounted to swing on a fixed pivot, the arm being provided with a hub having inclined surfaces adapted to travel on like surfaces formed on a sleeve mounted to turn with the said arm in one direction, and adapted to be held in a fixed position when the arm moves in an opposite direction by a collar secured on the said pivot.

The invention also consists of certain parts and details, and combinations of the same, as will be hereinafter described and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement as applied, parts of the track being shown in section. Fig. 2 is an inverted plan View of the improvement; and Fig. 3 is a side elevation of a modified form of part of the improvement.

The carrying ortransporting device of any approved construction is provided with the usual rails A between which pass the cables B adapted to move the cars traveling on the rails A. Each of the cables B is adapted to rest on a grooved pulley C journaled on a pin D secured in the head E formed on one end of an arm F, mounted to turn horizontally on a pivot Garranged vertically and secured on the bottom flange of one of the rails A. The

head E is provided with a projecting lug E adapted to rest on akeeper A secured to the base flange of one of the rails A, as plainly shown in Fig. 1, so that the arm F is supported on the cable supporting end, to prevent undue strain on the pivot G by the weight of the cables resting on the pulleys O. The arm F is provided on its under side with a hub F set on the upper end of a sleeve I-I mounted to turn loosely in one direction on the pivot G, the said sleeve being prevented from turning in an opposite direction by a collar .1 held on the square lower end G of the pivot G. The lower edge of the hub F is formed with two inclined surfaces F and F mounted to travel on correspondinglyshaped surfaces H and H formed on the top edge of the sleeve H. The straight vertical back F of the hub is adapted to abut against a corresponding straight edge H formed on the sleeve H so that the arm F can swing in one direction on the upper edge of the sleeve I-I without moving the latter as the back F thus moves away from the edge H the said arm F then rising on the pivot G by the incline F traveling up the incline H. When the arm F swings in the opposite direction and the straight edges F and H are in contact with each other, then the sleeve H turns with the hub F. The lower edge of the hub H is formed with the inclines H and H mounted to travel on corresponding inclines I and I formed on the top edge of the collar I. The incline H is located directly opposite the incline H and curves in an opposite direction, as plainly shown in Fig. 1, the other incline H being located opposite the incline H and also extending in an opposite direction. A straight edge H connects the ends of the inclines H and H with each other and this straight edge is adaptedjo abut against a cor: responding straight'edge 1 formed on the collar I at the ends of the inclines I and 1 Now, it will be seen that when the arm F swings in the direction of the arrows a,then the incline F travels up the incline 11 so that the arm F rises on its pivot G and the sleeve H is held stationary on account of the straight edge H abutting against the straight edge I of the fixed collar I. When the arm F swings in the inverse direction of the arrow a, then the abutting edges F and H ICO cause a turning of the sleeve H so that the straight edge H moves away from the straight edge 1 at the same time the sleeve I-I rises owing to the inclines H and H traveling up the inclines I and 1 The rising of the sleeve H causes a like rising of the hub F and arm F.

Now, it will be seen that when the device is in use and a cartravels in the direction of the arrow Z) and finally strikes the head E, then a swinging motion is given to the arm F in the direction of the arrow a, as above described so that the arm F with its head E nearly makes a quarterturn and thus moves out of the path of the car to permit the latter-to pass. As soon as the car has passed the arm F returns automaticallyto itsnormal position, as the inclines F and F travel downward on the inclines H and H on the sleeve H now held in a fixed position as above described. When the car travels in the inverse direction of the arrow 1), then it strikes the head on the other side and causes the arm F to swing in the inverse direction of the arrow a until the arm permits the car to pass, the arm nearly making one quarter turn. When the arm travels in this direction, the sleeve H turns with the hub F as above described and when the car has passed, the sleeve H and the arm F return to their normal position, as the inclines H and H travel down the inclines I and 1 respectively.

In order to counterbalance theweight of the head E and the pulley O, I provide the outer end of the arm F with a counterbalancing weight J or with a second head E similar in construction to the head E and also carrying a set of pulleys C. Now, when the pulleys O in the head E have become worn the other head E with its pulleys C may be brought into use under the track rails A to support the cables B, it being understood that the head E is then the outer part of the arm instead of theinner part, as above described and shown in the drawings. In order to make this change,the position of the collar I is changed on the square end G of the pivot. G by giving the said collar a half-turn before inserting it on the lower end of the pivot G.

Itwill be seen that by this device the cables are supported during the time the car moves away from the device, and the latter is free to swing out of position when the car strikes it, and automatically returns as soon as the car has passed.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A cable support comprising an arm mounted to turn and adapted to support the cable, a hub held on the said arm and formed with inclines, a sleeve mounted to turn and adapted to be engaged by the inclines on the said hub, and a fixed collar adapted to be engaged by the said sleeve to hold the latter in position when the arm swings in one direction and to permit the sleeve to turn when the arm swings in an opposite direction, substantially as shown and described.

2. A cable support comprising a fixed pivot, an arm mounted to turn on the said pivot and adapted to support the cable, a hub formed on the said arm concentric to the said pivot and provided with inclines and a straight edge, a sleeve mounted to turn on the said pivot and formed at its upper end with inclines adapted to be engaged by the hub inclines, and also provided with a straight edge adapted to be engaged by the straight edge of the hub, substantially as shown and described.

3. A cable support comprising a fixed pivot, an arm mounted to turn on the said pivot and adapted to support the cable, a hub formed on the said arm concentric to the said pivot and provided with inclines and a straight edge, a sleeve mounted to turn on the said pivot and formed at its upper end with inclines adapted to be engaged by'the hub inclines, and also provided with a straight edge adapted to be engaged by the straight edge of 'the hub, and a collar fixed on the lower end of the said pivot and provided with inclines adapted to be engaged by inclines on the lower end of the said sleeve and also provided with a straight edge adapted to be engaged by alike edge on the lower end of the sleeve, substantially as shown and described.
