STATES CHARLES GARR'AIBRANT, OF BROOKLYN, NEW YORK.

SAFETY TAKE-UP SPRING.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed April 16, 1915. Serial No. 21,722.

To all whom it may concern Be it known that I, CHARLES GARRABRANT, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented certain new and useful Improvements in Safety Take-Up Springs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a safety take up spring.

An object of the invention resides in the provision of a device of this character which may be applied to a rope or other flexible member so as to take up the shock applied to said member.

It is particularly useful in connection with bell and trolley ropes on street cars, for a driving line for a horse, for a clothes line or in fact for any flexible member similar to a rope which is subjected to sudden shocks.

A further object of the invention resides in so constructing thedevice that it may be readily attached to the rope between the ends thereof.

With these and other objects in view, such as will appear as the description progresses my invention comprises the combination an arrangement of parts as set forth in and falling within the scope of the appended claims.

Referring to the drawing: Figure 1 is a side elevation of my device illustrating one of its uses, that is, where it is connected to the bell rope of a car. Fig. 2 is anenlarged side elevation. Fig. 3 is a plan view. Fig. 4 is a side elevation, showing the position of the parts of the device when a force is applied to the rope.

Referring to the drawing like parts are indicated by like characters throughout the several views. In the embodiment of my invention shown in the drawings, I have illustrated my device formed from a continuous piece of spring metal which is circular in cross section. The device comprises an arm 1 which has an open loop on the end thereof and a second open loop 3 spaced from the first loop. The loops 2 and 3 are in alinement with each other so that a rope may be passed readily therethrough and will be free to slide therein. Formed integrally with this arm 1 and extending at right angles thereto is a body portion 4 which is of obtuse angular formation and has a spring 5 formed from the material thereof between its ends. The end of the body portion is coiled so as to form a second spring 6 and is then extended so as to form an arm 7 which normally extends at an acute angle to the arm 1 and has an open loop 8 on the end thereof.

As shown in the drawing when the device is used on a rope, which is indicated by the reference character 9, the rope passes through the open loop 3, thence downwardly through the loop on the arm 7 and thence upwardly through the loop 2 on the arm 1. One end of the rope is secured, for instance, as shown in Fig. 1, to a bell 10 and the other end to a suitable stationary member. When there is no force applied to the rope and the parts of the device are in their normal positions there will be a loop 11 formed in the rope. When a force is applied to the rope, however, the arm 7 is pulled toward the arm 1 and the loop 11 tends to straighten against the action of the springs 5 and 6 and thus the shock on the rope will be taken up. It is of course to be understood that the device may be made of metal which is stiff enough to retain its normal form under ordinary conditions, but when an extraordinary strain is applied thereto the arms 1 and 7 will move toward each other and the loop 11 thus partially straightened out.

From the foregoing description it will be seen that I have provided a device which may be used in various connections to take up the slack in the rope and take the strain off of the same.

I have so constructed the device that it will be simple to manufacture and very readily applied.

WVhile I have illustrated and described a particular embodiment of my invention, I have merely done so for the sake of convenience and I do not wish to be limited to that particular embodiment as it is obvious that numerous changes may be made within the details of construction thereof without in any way departing from the spirit of the invention or exceeding the scope of the appended claims.

What I claim is 1. In a device of the class described, consisting of a continuous piece of resilient wire bent to form diverging arms and an angular body portion connecting said arms, one of said arms having a pair of spaced loops formed therein and the other of said arms having a loop on the end thereof, the body portion having a plurality of springs formed therein.

2. In a device of the class described, a continuous piece of resilient wire consisting of diverging arms, a body portion extending between said arms, one of said arms havingmeans thereon for supporting, slidably, a rope at two points and the other of said arms having means thereon for slidably engaging the rope at one point.

In a device of the class described, a

pair of spaced arms, one of said arms having 1 a means thereon for slidably engaging a rope and the other of said arms having means thereon for slidably engaging the rope, and a body portion extending between said arms,

formed therein constructed and arranged to force the arms away from each other.

In testimony whereof, I afiix my signature, in the presence of two Witnesses.
