To all whom it may concern.-

Be it known that we, FRED E. DERRICK and SOLOMON C. Bao'r'r, citizens of the United States, residing in the village of Lansingburg, in the count-y ot' Rensselaer and State of New York, have jointly invented certain new and useful Improvements in Electric Alarm- Olocks, of which the following is a specification, reference being had to the accompanying drawings.

The general objects of our improvements are to furnish a clock having mechanism for Operating an alarm at a predetermined time with electric contacts and means for causing the action of the winding-shaft of the alarmoperating mechanism in running down to establish electric connection between said contacts, and thereby close an electric circuit embracing said contacts, an electric source, and an electromagnetic alarm, to provide means for readily establishing and breaking electric connection between said electric contacts of the clock and the terminal conductors of an electric circuit embracing an electro-magnetic alarm and electric source, and to provide means by which the winding-shaft of the alarmoperating mechanism. of the clock can be caused to either establish or not establish electric connection between said electric contacts when the winding-shaft runs down.

In the "aforesaid drawings, Figure 1 represents the front side of a mechanical alarmclock, an electric source or galvanic battery, and a self-acting electromagnetic alarm, each of a kind common in market, all connected together by electric conductors and embodying one form of our invention. Fig. 2 is an elevation of the rear side of the clock shownin Fig. 1, with one form of a portion of our invention applied thereto; and Fi 3 shows'on a larger scale parts of the same clock and its support in elevation and in partial section at the line 2 z in Figs. 1. and 2, as viewed in the direction of the arrow Fig. 4 is an elevation of the rear side of the same clock shown in Figs. 1 and 2, with modified parts of our invention applied thereto, and Fig. 5 showson a larger scale parts of the same and a partial section at about the line a: w in Fig. 4, viewed in the direction of the arrow to. Fig. 6 shows a portion of the rear side of the same clock with modified parts of our invention. Fig. 7 rep resents the rear side of another mechanical alarm-clock of a common kind with one form of a portion of our invention applied to the clock and Fig. Sshows on a larger scale a sectional elevation of parts of the same at about the line a c in Fig. 7 as seen in the direction of'the arrow at. Fig. 9 showsthe rear side of another mechanical alarm-clock of a common kind with another form of a portion of our in- Vention, and Fig. 10 shows a part of the same on a larger scale, viewed in the direction of the arrow t. Fig. 11 shows a part of the rear side of the alarm clock represented in Figs. 1 6 5 electromagnetic alarm can be close together, 7 5

or at any desirable distances apart, and are to be connected together by any suitable electric conductors, as b.

O is a common switch or button, by which the electric circuit can be conveniently broken and closed by hand.

Dis the usual windingshat't of the alarm mechanism, which can be of any ordinary or suitable kind,having an hour-circle and index and retaining and releasing parts, the sameas in the common and well-known mechanical alarm-clocks. The shaftD has a laterallyprojecting metallic key, arm, or part, E, by which that shaft and the alarm mechanism are wound up by hand, as usual. anism and winding-shaft run down, the shaft and its key or arm turn in the direction ofthe arrows.

To provide means for causing the action of thewinding-shat't of the alarm mechanism to 9 5 close an electric circuit when that shaft runs down,or is stopped in its runningdown movement, we furnish the clock with a stop, against which the key or arm on the winding-shaft shall strike and be arrested with the shaft in running down, and with two electric contact pieces, one insulated from the other and so arwhich will 0 When the alarm mecho ranged in respect to the winding-shaft with its key or arm that when they are arrested in running down by said stops, electric connectionshall be thereby established between the two electric contactpieces in any manner,substantially as hereinafter setforth. The metallic key or arm E on the windingshaft D can serve as one of said electric contacts, and then has electric connection with the clock-case A by the metallic shaft D and the metallic gearingframe, which supports the shaft and is socured in metallic contact with the case, as usual in such clocks.

F is the other electric contact-piece, which is mounted 011 the case A, and is insulated therefrom, as indicated by the heavy black parts 1', and is thus insulated from the key or contactpiece E on the winding-shaft when it is suitably wound up, as shown by full linesin Figs. 6, 7, 9, and 11, and by dotted linesin Figs. 2 and t.

In Figs. 2, 4, 7, and 9 the contact-piece F serves as a stop, against which the part E on the winding-shaft D strikes, and is stopped in its running-down movement, and thereby establishes electric connection between the two contact-pieces.

In Fig. ll. a metallic spring contact-piece, e, is secured to and in metallic connection with the case A, and extends between the insulated contact F and the arm E on the winding-shaft. When the shaft is wound up suitably,the part E is away from the spring part c, which is then away from the part F,-as shown in full lines. \Vhcn the alarm mechanism of the clock is released and the winding-shaft D runs down, the part E of the shalt strikes against the spring-piece e and presses and holds it against the part F, and is thereby stopped in its running-down movement, and thus by its action establishes electric connection between the contact-pieces F and c.

In Fig. (if is a metallic spring-piece, which is secured to and insulated from the case A, and is separate from the insulated part F on the case. Vhen the shaft D is suitably wound up, the part B on the shaft is away from the parts f and F, as shown in full lines. hen the shaft is released and runs down, the metallic part E first meets and bends the spring f, and next, while in contact with the spring, comes in contact with and is stopped by thepart F, and thus establishes electric connection between the parts E and j, and between the parts E and F, and between the parts F and f. By having the spriug f sufficiently stiff it will stop the running-down movement of the part E, so as to establish electric connection between the parts E and f only. Upon removing the part f the part E will be arrested by and held against the part F, so that electric connection will then be established between the parts E and F only.

To provide means for readily connecting the two terminal conductors of an electric circuit embracing an electric source and an electrical alarm with the aforesaid two electric contacts on the clock, we secure upon themetallic clock-case two attachments which are respectively adapted to receive and form electric connection with the-two terminal conductors, andhave one of said attachments in electric connect-ion with the clock-case and with one of the two electric contacts, and the other attachment insulated from the case and in electric connection with the other of said electric contacts.

In the drawings one such attachment, G, is shown secured to and in metallic connection with the clock-case, and thereby in electric connection with the contact-piece E or c, as hereinbefore specified, and the other attachment, H, is shown secured to and insulated from the case by the parts 1', and in metallic connection with the contact piece F, which is secured to that attachment.

In Figs. 4: and 9 the attachments G and II are like common binding-posts, and are adapted to receive and clamp fast the wire or pinform terminals, as p 1, of the electriccircuit conductors.

In Fig. 4 the parts G and II are shown arranged so that the clock can be thereby suspended from the conductor terminals.

In Figs. 1, 2, 3, t3, 7, and 11 the attachments G H are in the form of eyes, rings, or hooks g h, by which the clock can be freely suspended, as shown in Fig. 1, from two conductor terminals in the form of pins or hooks q, Figs. 1 and 3, secured at a suitable distance apart to and projecting from an insulatingsupport, I, so that electric connection shall be instantly established between said terminals and the electric contacts of the clock by mere- 1y hanging up the clock by its said ring or hook attachments from the correspondingly spaced conductor terminals, as indicated in Figs 1 and 3.

'When theterminal conductors of the electric circuit through the battery 13 and electric alarm O are respectively connected with the attachments G- and H, which are respectively in metallic connection with the contact-pieces E,or e and F,in the clocks represented in Figs. 2, 4, 6, 7, 9, and 11, the circuit will be completed when the windingshaft D runs down, and thereby moves and holds its part E in contact with the part F in Figs. 2, 4, 6, 7, and 9, or thepart c in contact with the partFin Fig. 11. When the circuit terminals are connected with the attachments G and H in Fig. 6, the circuit will be completed when the shaft runs down and its part E is stopped by the part F orfand in contact with the partf in metallic connection with the attachment H; and when the circuit terminals are connected with the attachments H and II, Fig. 6, the circuit will be completed when the winding-shaft runs down and its metallic partE is stopped by and in contact with the parts Fand f. \Vhen the circuit is thus closed through the battery and electric alarm by the action. of the windingr 351,746 i a shaft of the alarm mechanism when it runs down, the electric alarm will continue to act until the battery becomes too weak to operate the alarm, or until the circuit is broken,which breaking of the circuit can be conveniently accomplished by hand by means of the switch 0 in circuit, and preferably away from the clock and near the electric alarm. Commonly, the electric alarm and switch will be in the sleepirig-apartment and the clock in a distant room. The circuit is to be left open at the switch until, and there closed by hand when, the winding-shaft of the alarm mechanism shall be by hand turned back or wound up a portion of a revolution by the key or part E, and retained by the alarm mechanism of the clock away from the part F, and ready to be released to run down at a predetermined time indicated by the alarm-setting dial and index on the clock.

Vhen the electric alarm is used and operated in connection with an alarm-clock, as

above described, the mechanical alarm of the clock may strike by its hammer J on the bell K while the winding-shaft runs down to its stop or the hammer or the bell, or the bell and hammer may be absent from the alarm mechanism of the clock.

To provide means by which the windingshaft of the alarm mechanism in running down can be. caused to stop and to close the electric circuit of an electric al'arm,as above described, or to freely run down and cause an alarm to be sounded by the alarm mechanism of the clock alone, we make one or the other, or both, ofthe two electric contact-pieces on the clock or the arm or key on the winding-shaft, suitably adjustable. For this purpose the contact-piece F in FigsQ and 3 can be turned to and fro and held on its supporting-stem 0, Fig. 3, from its position in full lines in Fig. 2 to itsplaee in dotted lines at a, where it will be out of the path of the part Eon the winding-shaft.

In Figs. 4 and 5 the attachment H with the stop-piece F can be slid to and fro and secured on the rim m of the cloclcease from its place in full lines in Fig. 4 to where it is shown by dotted lines at Z.

In Figs. 9 and 10 the key E is pivoted in the head of the shaft D, and whenturned up, as shown by dotted lines at is in Fig. 10, will pass over without touching the screw-stop F, which latter can be turned back, as indicated by dotted lines at 9', so as to be out of the path of the part E when it is turned down, as shown in. full lines.

In Figs. 7 and 8 the part E is a doubleheaded screw-stem fitting in a female screw, through the head of the winding-shaft, so that the part E can be turned with endwise movement to and fro from its extended position shown by full lines to its place in dotted lines at t in Fig. 7, where it will not come in contact with the part F in the rotation of the winding-shaft.

In Figs. 6 and 11 the stem E fits and is mov able to and fro radially in asoeket through the head of the winding-shaft, which. is furnished with a clampscrew, d, by which the part E canbe fastened when extended, as shown in full lines, and when retracted, as indicated by dotted lines, at 0, so as to nottoueh either of the parts F, f, ore, as the winding-shaft revolves.

In Fig. 1 the electric conductors b are shown connecting one pole of the battery B with one metallic clock-supporting pin or hook, q, and connecting the other pole of the battery with the electric alarm O, and that alarm with the handswitch O, and the latter with the other metallic clock-support, 1).
