COMPENSATING DEVICE FOR RAILROAD SIGNALS, SWITCHES, 800.

SPECIFICATION forming part of Letters Patent No. 578,293, dated March 2, 1897.

Application filed September 25,1896. Serial No. 606,951. (No model) To all whom it may concern: G designates a lever which is fulcrumed in 50 Be it known that we, JOSHUA WV.

(Not shown.)

L designates a plurality of chains which have one of their ends suitably secured to the beam G or other point, while their other ends are attached to a link which is attached to the pin which passes through the pulley O. M designates a strap or yoke which de pends from the pulley O and carries the weights N therein, the same being increased or diminished, as desired, by the addition of other weights P, said latter weights being connected to each other by means of the supporting devices Q.

In Fig. 4 we have shown another embodiment of the principle of our invention, E designating the yoke, as before, in which is journaled the corrugated disk R, which is adapted to be locked and engaged by the corrugated pawl S, which is eccentrically mounted, said pawl having a body portion T, to which the counterbalance U is attached, to which one end of a suitable link-and-lever connection may be secured, while the other end thereof is attached to any desired fixed point, said pawl T being also provided, if desired, with a spring P of substantially the same construction as that seen in Figs. 1 and 2.

The operation is as follows: If we suppose the lever A to be moved from the right to the left, the arm 0 will be raised and the arm D lowered. As the arm 0 rises the connection S, which in the presentinstance is arod, will pass through the opening in the lever G as the latter rises and the spring P of the counterbalance K will cause the nose M of the'pawl to interlock with an adjacent tooth of the ratchet-wheel N. The latter, being now prevented from rotation and the chain A being prevented from movement relative thereto and being lifted upwardly with the yoke, wheel N, and arm C, will exerta pull 011 the connection 13 in the direction of the arrow, thereby imparting the proper movement to the signal arm, switch, 850. The arm D has in the meanwhile been descending, and as soon as it has reached a certain predetermined inferior position the nut S on the rod S will disengage the lever S which corresponds to the lever G and will unlock the pawl automatically from the teeth of the disk J, thereby allowing said disk to freely revolve, and any slack on the connections A and F will be immediately taken up by means of the traveling weights N or P, it being understood that the arm 0 is now in elevated position, while the arm D is in depressed position.

The operation of the mechanism seen in Fig. 4, it is thought, will be clearly understood from the foregoing, it being only necessary to substitutethe corrugated disk R and the corrugated eccentric S for the ratchet-wheel N and the pawl L, having the nose M, as already described.

In the preferred embodiment of our invention we employ weights substantially as seen in Figs. 5 and 6, N designating the weight, having the end portions 13 with an offset neck or body portion 0 the same having the face D raised above the surfaces of the end portions E the sides D of said neck being rounded, and each weight having also holes E therethrough for the insertion of suitable attaching devices, as seen in Fig. 1.

The manner of inserting the weights in position will be apparent from Fig. 6, in which one weight is shown in position and the other in the act of being inserted in place, the latter weight having its thinner portion introduced, first, into the strap or yoke M and bein g afterward turned into position, the weights, when finally superposed upon each other, being interlocked, as is evident, whereby there is no liability of accidental displacement or dislodgment of the same.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
