Application filed July 18,1900. Serial No. 24,097. (No model.)

.To ztZZ whom it may concern:

Be it known that I, LEONIDAS G. WooLLnY,

acitizen of the United States, residing at Ken ton, in the county of Hardin and State of Ohio, have invented certain new and useful Improvements in Fire-Alarm-Telegraph Repeaters; 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 to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of refreference marked thereon, which form a part of this specification.

My invention is in the nature of an improved fire-alarm:telegraph-repeater apparatus especially designed for operating mechanically any desired number of magneto-generators, each one of which is arranged when mechanically operated to produce an independent electrical circuit for operatinga separate instrument, (one for each generator,) the.

several parts being cooperatively arranged, so that when an alarm is turned in at any one of the alarm-transmitting boxes in the circuit with the striking or annunciator apparatus each one of the magneto-generators coupled with the system will be energized mechanically by the action of a movable part (preferably the striker) of the striking apparatus, such mechanical operation of the means for generating the sub or independent electrical circuits being provided to avoid the use of expensive battery-power'such as has heretofore been used for operating the said magneto-electric generators.

In its generic sense my invention comprehends, in combination with a bell-striking mechanism within a fire-alarm circuit set into an operative condition whenever an alarm is sent in, a magneto-electric generator and intermediate mechanical connections joining said magneto generator with the striking mechanism, whereby by reason of a direct mechanical connection between the striking mechanism and the generator said generator will be put into motion during the time the striking mechanism is active and said generator stopped when the striking mechanism is inactive.

Heretofore, so far as I know, in fire-alarmrepeating apparatus the repeaters have all been placed in the same circuit and said repeaters operated electrically, thereby making it necessary to provide a large amount of electrical energy for such purpose, which has rendered the maintenance of said apparatus costly, and by reason of their dependence on the stored-up electrical energy the operation of said apparatus has at times been found not entirely reliable. My present invention differentiates from the electrical method of energizing the repeater-circuits by providing an electromechanical power independent of the circuit that controls the striking apparatus, but controlled by the mechanical power created at each active operation of the striking apparatus, dispensing, as it were, with all battery or supplemental electrical energy for bringing into action the repeater-circuits.

In carrying out my invention I utilize the active movement of the striking apparatus as the power mechanical for bringing into action the magneto-generators that control the repeating or other subordinate devices, and said power may be harnessed with the generator in various ways; but I prefer to connect same directly with the hammershank, as I obtain the best and most positive results and a convenient way for imparting motion to the generator.

In its complete nature my invention also embodies certain details of construction and peculiar combination of parts, all of which will hereinafter be fully explained, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which-.-

Figure 1 is a view illustrating an ordinary bell-striking mechanism in circuit with a number of fire-alarm transmitters or boxes and a series of independent magneto-electric generators mechanically connected with the striking mechanism, and Fig. 2 is a view of a modified arrangement of the mechanical means for joining the magneto-electric generators with the striking mechanism. Fig. 3 is a diagrammatic view illustrating a generic arrangement of my invention hereinafter specifically referred to.

In carrying out my invention I utilize a striking mechanism of any well-known construction that includes a rocker member for imparting the proper striking movement to the bell tapper or arm located within a firealarm system, also of any well-known and approved type. In the drawings I have illustrated diagrammatically a fire-alarm system the circuit-wires A of which are cooperatively joined with the alarm transmitters or boxes B and with the striking mechanism, (indicated generally by S,) which mechanism, as shown, includes a suitablebase 2, upon which is mounted the winding stub or spindle 3, the outer end of which is journaled in the crossframe 4, and to one of the spacing-posts 5 upon the frame 4i's connected one end of the striker-arm-operating spring 6, the other end of which connects with the winding-spindle 3 in the usual manner.

7 designates the escapement-wheel; 8, the pawl; 9, the paWl-tripper devices; 10, the magnet for controlling the said tripper devices, and F the strikerarm, mounted on the rock-shaft G, all of said devices being of a well-known construction and form per se no part of my invention.

Upon one end of the shaft G is fixedly mounted a crank arm 9 of any suitable length, and to this arm, preferably at its outer end,'is pivotally connected a series of connecting-rods H, each of which acts as an independent powertransmitting means and each connects with a crank-arm 'L on the armature m of a magneto-electric generator I, each of which is in an independent circuit J of any desired length, and in each circuit J is disposed an electrically-operated mechanism K also of suitable construction-say, for example, an electromechanical repeater or striker, a recording-register, or bell-tapper.

By combining a magneto-electric generator with a striking mechanism in the manner described it is manifest that each time the bellstriker F is operated the movement of the cooperating parts will operate the crank-arm g, the movement of which is mechanically transmitted, through the rods H, to all of the generators I harnessed therewith, the impulses transmitted to the said generators corresponding with the operations of the striking mechanism. The armatures of the generators are of the Siemens or H form, and when the armatures or rotators cut across the stationary magnets electric impulses are sent through the circuits of said generators, which set into' operation the instruments within the energized circuits J of whatsoever kind. As but Very little power is required for bringing into operation the generators I, it follows that no material extra energy is needed beyond the normal for operating the striking mechanism, and hence I utilize what has heretofore practically been a waste force for maintaining the electric circuits for the repeating devices. Thus as the operation of the magneto-electric generators is accomplished entirely by mechanical means the necessity of adding increased resistance in the main fire-alarm circuit is avoided, and, furthermore, a large amount of battery-power is saved and absolute accuracy of operation of the devices in the supplemental or generator circuits is insured, as all contact-points which are so liable to becomeoxidized and dirty are done away with, and by reason thereof a cheaper, better, and more uniformly and positively operating fire-alarm-repeating system is provided, this being made possible, as no matter in what condition the magneto-electric generators are they are sure to generate an electric current when the armature passes the pole of the permanent magnet.

By connecting the rods H to the'crank memberg of the rock-shaft, as shown in Fig. 1, the striker-arm may be omitted and the repeating devices made to operate just as well, as the generators I are controlled by the action of the shaft G.

In Fig. 2 I have illustrated a modified arrangement of the upper connection for the rods H, in which they are shown as pivoted directly to the striker-arm. In this latter form the crank-arm G may be dispensed with.

IVhile I have illustrated my invention as a cooperative part of a fire-alarm-striking mechanism, it is manifest that the invention involves, generically, a means for operating a magneto-electric generator mechanically through the media of a mechanism having predetermined actions governedby electromechanical means. For example, the same may be joined to an electromechanically controlled signal apparatus having no strikerarm, as illustrated diagrammatically in Fig. 3 of the drawings.

Having thus described my invention, what I claim, and desire to secure bylLetters Patent, is-- 1. As an improvementin fire-alarm-repeating systems of the character described, the combination with the alarm mechanism; of a magneto-electric generator, and mechanical connections joining the said generator with the alarm mechanism, adapted to transmit power for operating the said generator, and to be set into operation by the alarm mechanism, when it is set into an operative condition,
