BELL-RINGER.

SPECIFICATION forming part of Letters Patent No. 343,059, dated June 1, 1886.

Application filt d June II, 1885.

To all whom it may concern.-

Be it known that I, ELIJAH G. NUTTING, a citizen of the United States, residing at Faribault, in the county of Rice and State of Minnesota, have invented certain new and useful Improvements in Bell-Ringers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawiugs,and to the letters andv figures of reference marked thereon, which form a part of this specification. 7

This invention relates to improvements in bell-ringers, and has for its object to provide a machine for operating a series of bell strikers or hammers to sound a general alarm on the release of a trigger from a time-wheel by electricity or other mechanical means; and it consists in combining with such machine a cam-lever for throwing the harness out of the path of the tappct-wheel, a time-wheel and spring-brake lever for starting and stopping the machine,and afan for governing the motion of the machine, said fan being adapted to be enlarged or contracted in diameter, to offer more or less resistance to the movement of the machine.

The invention further consists in the peculiar construction of hammers, and in the de tails of construction, arrangen'ient, and combinations of parts, as more fully hereinafter set forth and claimed.

In the drawings, Figure 1 represents a perspective view ofa machine constructed according to my invention, and shown placed in an Fig.2 is a plan view of the same. Fig. 3 is a side elevation, with a portion of the gearing broken away. Fig. 4 is a detail view of the spring-brake, brakepulley, timewheel, and releasing -trigger. Fig. 5 is a detail View of the hammer'operating mechanism, showing the cam-lever for throwing the same in and out of gear. Fig.6 is a modified form of a group of hammers. Fig. 7 is an enlarged perspective view of the fangovernor.

The frame A has suitablyjournaled thereto a tappet-whecl, 13, provided with a series of tappets, Z), projecting from its periphery and arranged in groups across the face of the Serial No.170,02-2. (No model.)

wheel. The number of tappets in each group correspond to the number of hammer-operating levers O which are mounted in the bracket c. The tappets of each group are arranged slightly in advance of each other, to operate the levers O successively. The space between the last'tappet of one group and the first of the next succeeding group should equal the space between the tappets of a group, in order that the levers C may be actuated during equal intervals of time to produce a harmonious ringing of the bell. just described is preferred, it is evident that i the tappets may be varied and spaced to suit the requirements without departing from the spirit of my invention. This tappet-wheel is driven by a suitable train of gearing, and as it revolves the tappets b,impinging against the ends of the levers O,operate the same and the bell-hammers D, which are connected to the outer ends of the levers G by wires or cords d.

A Windlass or drum, E, mounted in the frame A, has keyed to its shaft a gear-wheel, F. and a pinion,f. The former meshes with a pinion, G, on the tappet-wheel shaft 1), and the latter with a gear-wheel, H, on the shaft h, journaled in the frame. On the latter shaft is keyed a time-wheel, I. To one side of the tappet-wheel on its shaft is keyed a gearwheel, J, which wheel meshes with a pinion, j, on the spindle 7a, to the latter of which is keyed a gear-wheel, K, meshing with a pinion, l, on the fan-shaft L, the outer end of which projects through the frame A, and on which is secured the fan-governor M.

The governor-shaft L has keyed thereon a brake-pulley. at, around which passes asp ringbrake band, N, having a hook, n, on its extreme end, which bears on and is adapted to engage one of a series of stops, 1', on the timewheel I. These stopsi have threaded shanks,

and are intended to be removably secured to the wheel I, in order that the space between any two stops may be increased or diminished, for the purpose hereinafter set forth.

The fangovernor consists of an arni,O, centrally recessed or apertured to fit over the shaft L. The outer ends of this arm are provided with eyes. through which the rounded shank of laterally projecting arms 0 pass. Each of said arms are provided with curved wings P. The outer ends of the arms 0 are lVhile the construction wings and their consequent resisting surface to the surrounding medium.

Around the windlass E passes a suitable cord, to which a weight, Q. is attached to give motion to the train of gearing.

The machine may be located at any suitable point and connected to the bell-hammers by cords or wires, as already described.

The bell-hammers shown in Fig. 1 are sup ported by suitable brackets on a beam, D, of the belltower, and are arranged to strike upon the outside of a bell, A. and are preferably a'rranged to fall and strike the bell by their gravity. In Fig. 6 is shown a form of hammer principally designed to strike upon the inside of a bell. (Indicated in dotted lines.) Said hammer consists of the leverarm R,pivotally supported between upright posts It, and provided on its outer ends with the usual hammer. From its pivotal point an arm, 1-, projects, designed to be connected with the lever-arms O of the machine. Springs 1" project from opposite sides of the supporting-frame. and are connected to the lever at points above and below its pivotal point, to return thesame to its normal position. \Vhile the two sets of springs shown are preferred, it is manifest that one set may be dispensed with. It is also manifest that the form of the hammer may be arranged to strike either the in or out side of the bell,a.lthough the outside application is deemed preferable.

In operation, when it is designed to sound an alarm,- the parts being arranged as described, a trigger, S, is depressed by any suitable meanseither electrical, mechanical, or by hand-when the hook it. of the springband is disengaged from a stop of the timewhccl, and the band byits resiliency becomesdisengaged from the brake-pulley at, when the machine is free to operate, as already described, sounding a continuous alarm till the succeeding stop of the time-wheel engages the hook of the spring-band brake and causes the same to closely embrace the brakepulle,y, when the machine will stop till the trigger is again depressed. Thespeed of the machine is regulated by adjusting thewings of the fan, so as to present more or less of their surface to the resistance of the atmosphere. When it is desired to throw the hamtrier-operating levers out ofthe path of the tappet-wheel, during the winding of the machine or for other purposes, the lever T, attached to the end of a shaft, t, journaled in the bracket 0, is oper ated, as shown in full lines, Fig. 5, when a cam, U, attached to the shaft 25 is thrown uuder the levers G, causing them to assume the position indicated in full lines, Fig. 5, when their inner ends will be free of or out of path ol' the tappets of the wheel B.

To throw the levers in an operative posi i I claim, and desire to secure by Letters Patent, is-

1. la a bell-ringer, the combination of a series of bell-operating levers with a tappetwheel having tappets arranged in groups across its periphery,the number of tappets in each group corresponding to the number of levers, and each tappetbeing arranged equally' in advance of the other, whereby the levers are actuated sucessively, substantially as and for the purposes described.

2. The combinatiomwith the bell-operating levers, the tappet-wheel, and brake-pulley, of a brakeband and a time-wheel to engage such band and draw it round the brake pulley,substantially as and for the purposes described.
