JAMES GARVEY AND MATTHEW I-I. KIMBALL, OF SAN FRANCISCO,
CAL IF ORNIA.
Letters .Patent No. 83,623, dated November 3, 1868.
IMPROVEMENT IN BELL-PULL.
The Schedule referred to 'in these Letters Patent and making part of the same.
- To all whom it 'may concern.-
panying, drawings, making a part of this specification,-
in which*- Y Figure 1' is a plan;
Figu e 2 is a section; and l f The several other figures are. detached details of the separate parts composing our device.
lo enable others skilled in the art to properly understand, make, and use our device, we will proceed to describe it, as follows:
We employ, in the construction of our bell, the usual circular plate or disk A, which forms e foundation or base to attach the `working parts to. This' disk has cast in its centre, the rod or stem B, upon the end of which is screwed the sounding-gong C.
D is a lever, of peculiar shape, which swings on a fulcrum-pin, E, which passes through the lug F, cast on the plate or disk A.
On one end of the lever D is pivoted a piece, G, which we call the lifting-wedge. It is a little wedgeshaped piece, as shown in details, which connects with the end of the pullfbar H, by a wire passing through a hole in the lug on its side.
0n the lever D, and at the back of the wedge at I, a pin is provided to form a stop forthe wedge Gr, and prevent it swinging beyond the desired point, when operated on by the pull-bar.
The striking-hammer Kis formed, as shown 'in de' tails, of usual shape, having a little lug, L, drilled with a small hole upon its hub, to provide for the attachment of a spring, hereinafter to be mentioned.
,p There is also provided on the hub of the hammer K, at M, alittle projecting stem, which is of iron or steel, and may be cast or otherwise fitted in the hub, it being against this stem that the lifting-wedge bears in oper ating the bell.
The hammer itself swings on a pivot, N, cast in the 'plate A, and has provided for it the `usual stop, O, cast on theplate.
A spiral spring, P, 'connects the hammer and back end ofthe lever I) together, as shown in figs. 1 and 2, oneend of the spring hooking into the little lug on hub of hammer, and the other end hooking around Ia pin or stem projecting from the side ofthe lever D, at Q.
The pull-bar H, or handle,' is of common construction and arrangement, being simply a square rod of iron, with attached knob and handle onlone end. It is provided with the usual.guideplate or washer R.
The operation, the simplicity of which will be read ily recognized, is as follows: i,
The pull-har or handle H is draunfrward, and with it the attached lifting-wedge G, and lever D, to which the wedge is pivoted. In its forward movement,v the wedge bears against the stem M of the hammer, and, causing it to traverse its inclined surface, it is forced forward, and swings around the hammer on its pivot, until, having escaped the wedge, it is released, and, by the action of the spring P, is brought back with force, and, impingiug against the gong, sounds the bell.
The spring?, which acts to strike the hammer, serves also to return the lever D, and connected pull-bar, or handle, to their original position.
. In returning, after the bell is struck, the wedge Gr passes the projecting stem on the hammer, by swinging forward on its pivot to clear the same, when it shall have come in contact, the simple act of pulling the hell being sulicient to return the wedge-piece to its bear ,ing against the stop l, without aid of spring or other device. I
XVe will here state, that, by a slight alteration in the construction of the, hammer-,and lslight variation of the relative positions of the combined parts, as herein described, but without variation from the principle of construction involved, we may apply our invention in the manufacture of alarms, hotel, steamboat, and mining-gongs, such being usually of large size, and variously arranged, suitably to the positions they occupy, 85o., some being struck from the outside and others from the inside of the gong, and the pull-.bar receiving various directions, all of which separate conditions ren. dering suitable arrangement of working parts of this,
`our device, necessary to eachA case, and therefore we wish it to be known that we do not confine ourselves to the particular shape of relative position or direction of motion given to the combined or vseparate parts of our device, as herein described, but reserve to ourselves the right of making various equivalent arrangements, suitably adapted` to the various conditions which may arise'.
It will be observed thatin the adoption of the lift ing-wedge G, we encroach upon lthe claim made in our pending application for patent of the United States on improved pull-bell, but, inasmuch as we desireto be protected in these our additional improvements, sepa rately and distinct from our previous invention,v we will,
, without, reference to it, simply make claim to what may in the manner substantially as herein described,'andfor the purposes-.as set forth; 1
