SIGNAL-BELL.

SPECIFICATION forming part of Letters Patent No. 373,416, dated November 15, 1887.

.To aZZ whom, it may concern: y

Be it known that I, HENRY E. RUSSELL, Jr., a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Signal-Bells, of which the following is a specification.

My invention relates to improvements in signal-bells of the class in which the bell is struck by a spring-pressed hammer; and the objects of my improvement are simplicity and economy of construction and to provide asimple and efficient mechanism for imparting a double stroke to the hammer for every reciprocating movement of the operating-rod.

In the accompanying drawings, Figure l is a vertical section, partly in elevation, of my bell, the plane of section being indicated by the line w w, Fig. 3. Said figure also represents in section a portion of the door to which the bell is attached. Fig. 2 is a horizontal section of the same, partly in elevation, the plane of section being taken on line x x of Fig. 1. Fig. 3 is mainly an elevation looking upon the inside of the gong, the frame or standard and operating-rod being shown in section on the line y y of Fig. l; and Fig. 4-is a detached view, the same being a section on the line z z of Fig. 2.

A designates the door or siding uponwhich the bell is mounted, and B the base for securing the bell to said door. Extending from one edge of the base B and at right angles thereto is the plate-like frame or standard C, at one edge of which standard there is an angular arm, a, within which is the screw-post b, on which the gong D is mounted and secured in place by the nut d. The base B, the plate-like frame or standard C, and the angular arm a are all blanked out in a single piece of sheet metal and bent into the form shown.

E designates the tubular socket, preferably formed of sheet metal and provided with a side extension, e, by which it is secured to the plate-like frame C, so as to bring the body of the socket in axial alignment with the gong D. Within this socket is a spiral spring, f, one end of which rests against the arm a, while the other end surrounds the end of the operside of the socket E-the side toward the frame C--is slotted for a short distance, in order to give free movement to the trip-pin g.

Upon the plate-like frame C, I pivot the hammer-lever H, the body ot' which lever is extended to one side ofthe slot L and parallel thereto, as shown in Fig. 4. The hammer m is also secured to said hammer-lever. A spring, n, is secured to the post or stud, by which the hammer-lever H is pivoted and presses upon said hammer-lever to hold it in the position shown. Upon the pivot o, Figs. 1 and 4, I secure a three-armed tripping-lever, I, with one edge resting against the edge of the hammer-lever H. This tripping-lever has two of its arms, 2 and 3, substantially in alignment with each other, with the arm 3 extending farther from the pivot, or, in other words, longer than the arm 2. The tripping-arm 4 stands at right angles to the arms 2 and 3, and is beveled alike on both sides and has its end projecting partly over the sloth, and conscquently into the path of the trip-pin g.

By pushing upon the operating-rod F in a direction to compress the springf, the trippin g strikes the tripping-arm 4 of the tripping-lever I, and presses the short arm 2against the hammer-lever H and moves the same in a direction to draw the hammer away from the gong. As soon as the trip-pin g passes the trippingarm 4, the spring n throws the parts H I into their normal position, thereby imparting one stroke to the gong. Upon the operating rod being released the spring f forces it into its former position, and in doing so the trip-pin g strikes the tripping-arm 4, thereby impinging the long arm 3 against the hammer-lever H and moving it against its spring. As soon as the pin g passes the arm 4, the spring u returns the parts H I and imparts another stroke of the hammer to the gong. By making the arms 2 and 3 of the tripping-lever of the proper relative length,
