THE GRAPHIC Cfl-ILY UNITED, STATES PATENT OFFICE.
JAMES M. PEIRGE, OF JOLIET, ILLINOIS.
IMPROVEMENT IN RAILWAY-SIGNALS.
Specification forming part of Letters Patent No. 1S4,i06, dated November 7, 1876; application filed May 20, 1875.
To all whom it may concern Be it known that I, JAMES M. PEIRGE, of Joliet, in the county of ill and State of lllinois, have invented a new and useful Improve- 'IllGlliJfOI Railway-Signals, which improvement is fully set forth in the following specification,
reference being had to the accompanying speed of the approaching train; also, to raise the gate when the train passes the crossing.
Figure 1 represents the gate raised. Fig. Zrepresents the gate 'down, and flag shown, and the bell rung.
A represents the crank which the wheel presses down. At the opposite end of a shaft is the arm or crank B standing at nearly a right angle to the crank A. This is connected by a wire or chain to the crank O at any desired elevation to extend a wire to the opposite side uf a crossing, where it is attached to a spring, D, which allows the wire to move in the direction of the train, and at the same time to display a flag, F, and strike a bell, G, as each wheel passes the crank A. The spring D instantly draws back the wire, thus giving the speed of the approaching train. The gate H is dropped by the lever I, which is forced down by the spring D at the opposite the crossing the alarm does not operate, and
the crank A is brought to'place by the spring M.
I claim as my invention- The combination of the double cranks, levers, and springs, connected by wire, substantially as set forth, with the alarm-bell and rising and falling gate, all operating substan tially as shown and described.
