TAKE-UP DEVICE.

Specification of Letters Patent.

Patented Dec. 14, 1920.

Application filed June 14, 1920. Serial No. 389,043.

To all whom it may concern:

Be it known that I, Brennan B. Srrnns, a citizen of the United States, and a resident of Fort Bragg, in the county of Mendocino and State of California, have invented certain new and useful Improvements in Take-up Devices, of which the following is a specification.

My invention is an improvement in takeup devices, and has for its object to provide mechanism for automatically taking up the slack in the rope and for permitting slack to run out, as the pole moves up and down with the varying height of the wire, and especially designed for use with the trolley pole arrester forming the subject matter of my co-pending application No. 341,996, filed December 2, 1919.

In the drawings:

Figure 1 is a side view of a portion of a car having the improved arrester;

Fig. 2 is aside view, with the casing in section;

Fig. 3 is a vertical section in the plane of the axis of the reel;

Fig. 4 is an enlarged section;

Fig. 5 is an enlarged detail section at the axis of the reel; h

Fig. 6 is a face view of the reel;

Fig. 7 is a section on the line 77 of is- Fig. 8 is a partial face view of the controlling disk.

In the present embodiment of the invention the usual rope 1 is connected with the trolley pole 2 of the car 3 and this rope, at the end remote from the pole, winds upon a reel 4 journaled on a shaft 5 which is held in a housing 6 secured to the" end of the car, as .shown.

The reel 4 is mounted on a sleeve 7 which is movable longitudinally of the shaft 5 and is held from rotation with the reel by means of a pin 8 which engages a longitudinally extending slide 9 in the sleeve, it being understood that the shaft 5 is fixed.

At its outer end the sleeve has a marginal flange 10, which is engaged by an inwardly extending web 11 supported by a collar 12 mounted to move longitudinally of the shaft 5. This collar, as shown more particularly in Fig. 5, is flanged at each end, as at 13 and 14. One of the flanges 13 carries the web 11 and the other flange 14 is engaged by a coil spring 15 which encircles the shaft 5 between the collar 12 and a fixed stop 16 ing, at the end remote from the extension 18 and is secured thereto, and the said disk has in its periphery a series of radial openings 21, the casing 19 having openings registering therewith.

These openings are adapted for engage ment by a locking pin 22 which is mounted in a guide 23 to move radially of the disk and casing and is normally pressed away from the disk and easing by a coil spring 24. The spring is arranged between the easing and a stop on the pin, as shown, and it will be evident that when the pin engages an opening 21 the casing will be locked to the disk.

The reel 4 is normally pressed toward the casing 19 by the spring 15, and when the actron of the spring is unopposed the reel will be clutched to the casing 19, to rotate therewith. When the reel is in the position of Fig. 3 however, it is free from the shaft 5 and from the casing 19 and may move under the influence of a spring 25. This spring, as shown in Fig. 2, has one end secured to the reel in a direction to wind up the rope 1. The reel, however, is normally held out of position to engage the extension 18 and to be clutched to the easing 19 by means of an angle bar 26.

This bar has a portion mounted to slide through a guide 27 in the casing 6, parallel with the shaft 5, and a portion which is forked, as indicated at 28, and the arms of the fork engage the collar 12 between the flanges 13 and 14. The first named portionof the bar extends outside of the casing and has a head 26 as shown, for convenience in operating the bar, and when the bar is moved outwardly the collar will be moved therewith, as will also the reel, and the reel will be disengaged from the casing 19. When so placed, the reel may moveunder the influence of the rope and under the influence of the spring, the spring winding up the rope when the tension thereon slackens and permitting the same to move outwardly when tension s ncreased.

Means is provided for engaging the bar 26 to hold the reel in the position shown in Fig. 8. This mechanism is shown more particularly in Fig. 4t, and comprises a substantially rectangular frame 29 through which the bar 26 extends. This frame carries a pin 30 which is adapted to engage an opening in the upper edge of the bar, as shown, and the pin is normally pressed toward the. bar by means of a spring 81 arranged between the upper end of the frame and the side of the bar. The pin is slidable in the frame and the frame is slidable through a guide bracket 32 extending inwardly from the casing. The lower end of the frame is connected by a link 38 with a lever .34; which is pivoted to a bracket 35 extending upwardly from the bottom of the casing, and the end of the lever remote from the link 33 is-in position to engage the pin 22 and to press the pin into engagement with one of the openings 21 of the disk when the end of the lever remote from the pin is drawn downwardly.

An electro-magnet is arranged beneath the said outer end of the lever 34: and the magnet,,when it is energized, acts to draw down and hold the outer end of the lever down, that is, the end remote from the pin, and to hold the pin in engagement with one of the openings of the disk. The lever also acts to hold down the frame 29, and to keep the pin 30 in engagement wit-h the opening in the bar 26, and to hold the bar from inward movement and to hold the wire in the position shown in Fig. 3.

The winding of this electro-magnet 36 is interposed in the lighting circuit indicated at 37, and it will be evident that when the pole is pulled down so that the wheel does not engage the trolley wire, and the act-11 ating circuit is broken, the lighting circuit being also broken, the magnet will be deenergized, and that end of the lever remote from the pin may move upwardly. This upward movement of the outer end of the lever permits the spring 2 1 to move the pin 22 downwardly, to release the disk 20.

The same operation permits the frame 29 to move upwardly to release the bar 26, and the sprin 15 forces the reel toward the casing 19, and clutches the reel to the said casing. The casing 19 is a spring casing, containing a spring 38 having one end connected with the shaft and the other with the casing.

In operation, under normal conditions the parts are arranged as shown in Fig. 3, that is, the bar 26 is moved outwardly to withdraw the reel from engagement with the casing 19, and the pin 80 is engaged with the notch in the bar 26 to hold the bar in withdrawn position. The pin 22 is engaged with one .of the openings of the disk 20,

and with the lighting circuit of the car closed, the electromagnet 36 will hold the parts in such position. As the pole moves up and down following inequalities of the wire, the spring 25 will actuate the reel to wind up the loose rope or permit the rope to run out, so that the rope is held taut. Should, however, the wheel leave the wire the lighting circuit will be interrupted and the magnet 36 will be deenergized. The bar 26 will be released and the spring 15 will move the reel toward the casing 19 and will clutch the reel to the said casing. At the same moment the pin 22 will be withdrawn from engagement with one of the openings 21, thus releasing the casing, which will at once be rotated under the influence of the spring 88, to turn the reel in a direction to wind up the cord and pull the pole downwardly and hold the same down.

It will be evident that so long as the trolley wheel engages the wire the parts will be held in the position of Fig. 3, that is, with the reel free from the casing and free to follow the movements of the rope under the influence of the light spring 25, which is merely strong enough to wind up the slack rope. In case, however, the circuit is broken, as when the trolley pole jumps the wire, the spring operated casing 19 will be released, while at the same time the reel will be clutched thereto to cause the reel to be rotated by the spring 38 to wind up the rope and pull down the pole.
