J. S. LYNAM. FOR SIGNAL OPERATING WIRES.
GOMPENSATOR, N 0. 521,885.
Patented June 26, 1894.
\ UNITED S ATES PATENT OFFICE.
JOHN S. IJYNAM, OF \VINCHESTER, MASSACHUSETTS.
COMPENSATOR FOR SIGNAL-OPERATING WIRESL SPECIFICATION forming part of Letters Patent No. 521,885,-dated June 26, 1894. Application filed April 5, 1894- Serial No. 606,388. (No model.)
To all-whom it may concern.-
Beit known that'I, JOHN S. LYNAM, acitizen of the United States, residing at Winchester, in the county of Middlesex and State of Mas- 5 sachnsetts, have invented certain new and useful Improvements in Oompensators for Signal-Operating Wires; and I do hereby declare the following to bea 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.
My invention relates to improvements in compensators for the operating wires or cords of semaphores and it consists of novel means I for automatically taking up the slack of such wires caused by the expansion and also to allow the contraction of said wires; said means permitting said expansion or contraction without affecting the signal.
My invention is more fully set forth in the following specification and in the accompanying drawings, in which latter Figure 1.represents a side elevation of the devices embodying my invention, applied to the semaphore supporting post, the semaphore being at safety, and Fig. 2. represents a detail end elevation of the same.
A in the drawings represents the semaphore proper; Bits supporting post or standard; O the signal operating wire; D the compensator operating swing arm; E the compensator operating wire and F the compensator weight. of ordinary construction and is pivoted to the 3 5 post 13 near its upper end. Just below on the.
said post is pivoted the semaphore operating arm or lover a which is provided with a counterbalance weight a and is connected to the semaphore by the connecting rod 00*. Stop pins a are provided on each side of the lover a to limit its movements up and down. About midway of the height of the post is placed a bracket b to which the upper end of the swinging arm Dis pivoted. To thelower end of this swinging arm is secured a pulley wheel dby means of a double yoke (1' having a supporting bracket (1 which is secured to the side of the said arm. The wire E from the signal tower has its end provided with a 50 hook e which engages one end of the double yoke. A wire E provided with a hook e engages the opposite end of the yoke. This The semaphore or signal A is wire passes about a fixed pulley G supported by a bracket 9 on said post and is provided at its end with an operating weight F. The signal operating wire from the signal tower passes about the pulley d and up to the end of the signal operating lever.
It will be seen from the foregoing that both of the wires 0 and E will expand and contract 50 together and to the same degree as they are the same length and occupy the same position, and as the wire E expands or contracts the weight F is raised orlowered and the arm 'D and pulley d swung either to the right or 6 5 to the left as the case may be, thus taking up the slack in the wire 0 or allowing it to expand. I
When it is desired to set the semaphore the wire 0 is slackened and thus permits the lever a'to rise and operate the signal, the pulley 01 remaining in the same position as the wire E does not move during this operation, or at all except by expansion and contraction.
What I claim as my invention is- 1. In a compensator for signal wires, the combination of a supporting post, a signal operating lever pivoted on the same, a movable pulley and a stationary pulley, a wire from the signal tower passing over the sta- So tionary pulley and terminating in a weight and connected to and adapted to move the movable pulley as said wire expands or contractsand an independent wire from the signal tower passing about the movable pulley and connected to the semaphore operating lever, substantiallyas described.
2. In a compensator for signal wires, the combination of a supporting post, a signal operating lever pivoted on the same and pro-' vided with a counterbalance weight, a stationary pulley, a movable pulley, means for supporting said pulley but allowing it to move to the right or left, a wire from the signal tower connected to said pulley and adapted to draw it in one direction, a wire connected to the opposite side of said pulley and adapted to draw it in the opposite directi0n;said wire passing over the stationary pulley, a weight attached to the end of said wire and an inroo dependent wire connecting the signal tower and the semaphore and passing about the movable pulley, substantially as described.
3. In a compensator for signal wires, the
combination. of aisupporting post, a signal pulley and attached to the signal, substan- 1o operating'lever pivoted on the same, a' comi tially as :described. pensating arm pivoted at its upper end and In testimony whereof I hereunto affix my carrying at its lower end a pulley, a double signature in presence of two witnesses.
