IMPROVEMENT IN RAILROAD-SIGNALS.

Specification forming part of Letters Patent N 0. 161,519, dated March 30, 1875 application filed December 29, 1874.

To all whom it may concern:

Be it known that I, R. L. KLLPATRIGK, of Springfield, Clark county, Ohio, have invented an Improved Railroad Signaling Mechanism, of which the following is a specification:

Figure 1 is a side elevation; Fig. 2, a series of detail side views Figs. 3, 4, and 5, elevations (in section) of the hollow signalpost and its mechanism.

The invention will first be fully described, and then pointed out in the claims.

As a train of cars approaches a station, a wheel, Y, strikes an arm, P, whose hub 19 is loose on shaft 0, but is locked by projections 19, that fit into notches r of a sliding clutch, It, turning with said shaft. When the shaft 0 is thus rocked, its arm N turns the connected lever M, thereby pulling the wire L, that is attached to the crank-shaft 7c. The latter is connected, by a wirefk, with a loose arm, H, on a rock-shaft, I, where is also located a rigidly-attached angle-lever, G, in which is the vertically-arranged spring-catch F, beveled on its free end, and to which is connected a retracting-spring, g. The rocking of shaft I causes the catch F to turn the lever E, (that ordinarily rests on a bar, E1 thereby turning the armed rock-shaft G D, which acts upon the hammer-shaft, and thus draws back the hammer B. As soon as the catch F ceases to carry the short end of lever E, the spring of hammer-shaft causes the hammer to strike the bell A, and thus give the alarm.

When the shaft I is rocked by the approaching car-wheel, a rear arm, 2', is elevated, pulling the wire 1, lifting the catch it, and depressing its forward end, so as to allow loose arm H to be raised by a wire, G, actuated by a spring, F, at the top of hollow post B. This wire and spring are attached to a lever, IE at one end, while the other end of said lever works in and lifts an arm, D, rigidly attached to a rock-shaft, A, that carries the signal-card O. The latter is thus thrown down at the same time that the alarm is sounded. As soon as the car-wheel has left the treadles P Q, the spring g throws back the crank-lever G, with the loose arms H, that rest upon its'pins a: so, when the catch F resumes its position behind the short lower arm of 1c ver E, and, in turning back shaft I, depresses the arm i, that connects, by wire I, with the catch-lever h. The car-wheel now, passing over the treadle H at the station, rocks the shaft h, and, with its rigid arm H that has a side hook at the end, bears down the loose arm H until it has passed the spring-catch h, and is held on the under side thereof. The signal is now ready to be operated again by a train coming from either direction, as one wire, It, connects with a treadle mechanism on opposite sides of the station. The wire m or other flexible connection between the anglelever Gr and weight g, may be employed by passing it over pulleys W, to retract the lever.

Inorder to prevent the wheel from operating the treadle after a train has passed the station, I interpose between the clutch mechanism p p and It 1" the loose hub q of a treadle, Q, making on it and the sliding hub It corresponding but reversed inclines b b. When the cars have passed the station they will first strike the treadle Q, which, turning loosely on shaft 0, will, by the inclines b I), slide the part B from the one 19, disconnect them, and allow the treadle G to be turned loosely on the shaft, thus preventing any sound of the alarm.

It will be observed that the wire L passes under apulley, t, on outer end of the long arm of an an gle-lever, S, while the other end of the lever is provided with a spring-shaft, T. The wire it, connecting the upper end of the short arm of angle-lever, after passing under a pulley, it, extends to some point or fastening, which may, if desired, be adjustable. The spring-pressure thus brought to bear upon the wire, although not very great, will keep it taut under all ordinary circumstances.

\Vhat I claim as new is 1. The combination, with a shaft, 0, that operates an alarm mechanism, of the treadles P Q, having hubs p p q I), and the springpre'ssed sliding part-clutch R r b, arranged to operate in the manner described.

2. The combination, with wire L, of the angle-lever S, having pulley t, spring-shaft T, and holding-wire t applied as and for the purpose specified.

3. The combination, with hammer-shaft, of the armed shaft 0 D, lever E, cross-bar E were an gle-iever G, having spring-catch F, shaft I, having rigid hook-arm H the Wire G, spring arm H, and wires 70 L extending to treadle as F, lever E slotted arm 1), and signal-card and for the purpose described. shaft A, as and for the purpose specified.
