BELL-CORD CQUPLING.

SPECIFICATION forming part of Letters Patent No. 364,312, dated June 7, 1887.

Application filed March 528, 1887.

T aZZ whom it may concern.-

Be it known that I, CONRAD ALBERT $11713, a citizen of the United States, residing at Fairlnont, in the county of Marion and State of \Vest Virginia, have invented a new and useful Improvement in. Bell-Cord Couplings, of which the following is a specification.

The invention relates to an improved belleord coupling adapted especially for use on railway-cars, the object being to provide a simple and cheap coupling that can be quickly and easily connected and diseonneeted,and that will not accidentally come apart; and it consists in the construction and arrangement of the metal spring connecting strips at the ends of the sections of cord and the combination of said strips with other parts, as hereinafter described, and embraced in the appended claims.

In the accompanying drawings, Figure 1 represents a perspective view of the device attached to proper supports. Fig. 2 represents a central longitudinal section of the end of a cord having one side or section of the device attached. Fig. 3 represents a perspective view of one of said sections of the device detached. Fig. 4 represents a perspective view of a 1n odification thereof. Fig. 5 is a perspective view of portions of the two ends or coupling-hooks of my improvement. V

Referring to the drawings by letter, A A designate the meeting ends of two similar sections of bell-cord, and G C the similar'halves or sections of the connecting device respectively attached thereto. Each of said halves or sections consists of two similar strips, 0 0, having their front ends pointed or beveled outwardly and provided with the shoulders of c a short distance rearward from said points.

From the shoulder c of each strip 0 runs the straight portion or neck 0" a short distance rearyvard. The edge of the strip then inclines rearward and outward, as at c", after which both stripshave the same and an equal width to the rear ends. The strips are secured together with their shoulders c lying upon each other and pointing in opposite directions, a V-shaped notch, D, being formed between the points of the strips, and a space, D, of general rectangular form betwecnthe' necks c 0 Each of the said sections or catches is placed within and among the strands of the end of the corresponding bell-cord, and secured by Serial No. 232,752. (No model.)

rivets passing through the cord and strips. The whole is then firmlyand evenly wrapped with small cord, E, a piece of soft-rubber tub- 5 5 ing, F, passed thereon and bound over all by a suitable cord or other wrapping, the end of the tubing extending nearly to the points of the strips.

To connecttwo sections of cord provided with the device, the V-shaped notches formed by'the points of the latter are placed together at right angles, so that the points of the 0p posing sections or catches will have passed each other. The two sections are then twisted upon each other, so as to press apart the strips of which each are composed. The hook-shaped ends of the catches will then pass each other, and the shoulders of one section will engage and hold on the shoulders of the opposing see 70. tion, the elasticity of the strips preventing them from springingapart.

Torelease the two couplers C and 0', they are twisted so as to separate the hooked ends 0 thereof, when they may be readily drawn asunder by passing between each other.

The rubber tubing, byits contraction on the strips, also aids in preventing them from de taching from each other. It also prevents the points of the strips or catches from. injuring the hands of the person connecting the sections of cord, or any parts of the. car that they may touch, or breaking the windows in the doors of said cars.

Fig. 4 represents a modification of the device, in which there is substituted for one of the sections of the device a single strip, G, similarly secured to the end of a section of bell-cord, and provided in its outer or front end with a slot, 9, which may be engaged by the shoulders c of the opposing section. The device as described is simple, cheap, and durable, and cannot easily become accidentally disengaged.

Having described my invention, I claim- 1. I11 a bell-cord coupler, the combination, with the bell-cord, of two flexible tubes connected to the ends thereof and spring-couplings mounted within the said tubes and constructed to engage with each other and form a connection inclosed by the tubes, all substantiall y as described.

2. In a bell-cord coupler, the combination, with the bell-cord, of two rubber cylinders, F,

secured to the ends thereof, and the springcouplers O and 0, arranged in planes at right angles to each other and inclosed within each tube, and which are adapted to engage with each other, as set forth, and when coupled are entirely housed by the said rubber tubes, substantially as described.

3. In a bell-cord coupler, the combination, with the bell-cord, of the two springarms secured to the ends of said bell cord in planes at right angles to each other and adapted to couple, as set forth, substantially as described.

4. The combination of the sections of bellcord A A, the similar sections or catches, G O, composed of the strips 0 0, each pointed at its end and provided with a shoulder, a, and neck 0 forming between them the engaging Witnesses:
