ings, in which the same letters indicate l ke parts in each of the figures.
The nature of this invention will be understood from the specification and drawings..
Figure 1 is aface view of a door and frame, to which this invention is attached.
Figure 2 is a side view of the actuating-device, secured to theframe-work of the door.
a is the plate, to which the bell is secured.
b is the hammer, secured by its handle-huh, a, to
e is an actuating-arm, attached to the same hub, c, of the hammer-handle.
f is a spring, coiled around the pin g, one arm of which has its bearing against the bell-spindle, while the opposite end takes bearing against the hammerhandle, and holdsit (the hammer) at rest until acted upon by the actuating-device (see fig. 2) which is secured to the frame-work of the 'door. The hammer-handle may be extended through the hammer, so that the actuating-device may act directly upon the outer end thereof, and thus dispense with the independent actuating-arm 0.
While at rest, this hammer-handle or arm 0 takes to prevent the hammer from resting against the rim of the bell.
i is a wall-plate of the actuating-device, by which it (the device) is secured to the casing.
k is a stud-post, projecting forward at right angle from the plate 1, having a slit or opening in its outer end, in which the triangular-shaped vibrating catch an is secured by a pin passing through the stud Ia, and one corner or angle of said plate m.
This angular plate m is allowed'to vibrate back and forth in the slit, so that first one edge, then the other, is (by its vibration) brought into position parallel with the sides of stud-pin k, so that it will fall by its own gravity into position to actuate the bell-hammer, and be lifted, and again fall to its position, when the door is closed, in' readiness for a new operation.
This plate is held in an elevated, inoperative position, when desirable, by means of a latch, n, which enters an orifice, 0, formed in the side of the plate on. Thus the door may be opened and closedwithout actuating the bell'; and, when desirable to leave it in position for operation, it is only necessary to turn the latch back out of the orifice 0.
I believe I have thus shown the nature, construction, and advantage of this invention, so as to enable others skilled to make-and use the same therefrom.
What I claim, therefore, and desire to secure by Ixtters Patent, is- The arrangement of the triangular vibrating catchplate-m, stud and jamb-plate k a in combination with the actuating-arm c of the bell, substantially as described.
