Specification of Letters Patent.
Patented Oct. 29, 1907.
To all 'uihom it may concern:
Be it known that 1, PA UL LUX. a citizen of the United States. residing at Waterbury. .in the county of New Haven and State of Connecticut. have invented a new and useful Improvenwnt in .=\larm-(locks; and I do hereby declar the following. when taken in ct'nnu-ction with the accompanying drawings and the letters of reference marked thereon. to be a full. clear. and exact d seription of the same. and which said drawings cons t1- tute part of this specification. and represmit. in-
Figure 1. reverse plan view of a clock-movement provided. with my improvement. only such parts of the trains being shown as is necessary to illustrate the relation of my improved mechanism thereto. Fig. 2 a view in vertical section on the line ab of Fig. 1. looking from rear to front. Fig. 3 a corresponding view on the line c-(l of Fig. 1.
My invention relates to an improvement in that class of alarm clocks in which provision is made for readily converting the clock from a long or continuous alarm clock to an intermitttmt or spasmodic alarm clock, the object being to produce a simple, compact, reliable and convenient mechanism constructed with particular reference to being embodied in very small circular clocks of the kind commonly placed in uickeled sheet metal and known to the trade as nickel clocks.
With these ends in view my invention consists in a clock having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.
In carrying out my invcntio n as herein shown, I employ an alarm wheel 2 which turns from left to right with the shaft 3 of the third wheel 1 of the time-train which may be of any ordinary construction. The teeth of the Wheel 2 co-aet with the beveled nose of an alarm lever 5 constantly pressed toward the said wheel by a spring 6 secured to the front face of the intermediate movementplate 7. The lever 5 is mounted upon the projecting front end of an oscillating alarm-staff 8 journaled at its front end in the plate 7 and at its rear end in the rear movement-plate 9 and carrying a wire alarm stop arm 10 (co-acting with a radially arranged alarm stop pin 11 carried by a large collet 12 on the staff 13 of the escapenient wheel 14 of the alarm-train which may be of any ordinary construction. The staff 8 also carries a wire alarm cut-off arm 15 extending in the opposite direction from the stop arm 10 and arranged to be engaged by the inner end of a sliding manual cutoff comprising stud 16 mounted in a slot 1.7 in the rear movement plate 9 and projecting rearward through a slot 18 in the flanged disk-like back 19 of the clocl-z-case which, barring the said back, is not shown. A cupped friction washer 20 mounted upon the stud 16 engages with the front face of the plate 9 and holds the cut-off in its active and retired positions at the ends of the slot 17. When the cut-off is moved from right to left its inner end rides over the cutoff arm 15 and so rocks the staff 8 sutliciently to move the stop arm 10 sufficiently outward to clear it from the outer end of the stop pin 11. so that when the alarmtrain is let: off it will run continuously until the alarm spring runs down. for the reason that when the stop arm 10 disengaged from the stop pin 11. the wheel 1.4 is free to rotate from left to right under the restraint of the verge 2.1. of the verge arbor 22 which carries the bell hammer 23 which is arranged in position to strike the bell. The time and alarm trains and alarm let-off mechanisms of such clocks being well known, it has been deemed unnecessary to either show them or describe them.
To set the clock to operate as an intermittent or spasmodic alarm. the sliding cut-off is moved by the fingers from right to left so as to clear the cut-off arm 15. This leaves the spring 6 free to press the lever 5 toward the wheel 2. Now as the wheel 2 turns from left to right, its teeth will (to-act with the beveled nose of the lever 5 and push the same outward against the power of the spring 6 whereby the staff 8 will be sufiiciently turned on its axis to lift; the stop arm 1.0 away from engagement with the stop pin 11. When the alarm-train is released in the usual manner, the alarm will be sounded until the rotation of the wheel 2 by the time-train permits the lever 5 to drop off the next succeeding tooth of the wheel. When this occurs the spring 6 will act to move the lever 5 inward and thus rock the staff 8 so as to bring the end of the stoparm 10 into the path of the stop pin 1.1. which will engage with the end of the arm 10 and stop the alarm-train which will. however, be released again just as soon as the time-train has operated through the wheel 2 to again lift the lever 5 for the disengagement of the stop arm 10 from the stop pin 11. This cycle of operation will be continued until the alarm spring runs downv On the other hand, if it is desired to use the clock as a long or continuous alarm clock, the cut-off 16 is moved from left to right; whereby the cutoff arm 15 will be engaged and crowded inwardly with the effect of rocking the staff 8 so as to lift the end of the arm 1.0 away from the end of the stop pin 11 and so as to lift the beveled end of the lever 5 away from co-action with the teeth of the wheel 2. The alarm mechanism will now operate to sound a continuous alarm as though the wheel 2, lever 5 and other co-acting parts were eliminated from the clock.
In a convertible alarm mechanism, the combination with an alarm wheel operated by the time-train, of a spring-actuated lever co-acting with the teeth of the said wheel, an oscillating shaft by which the said lever is carried, a stop arm upon the said shaft, an alarm escape' ment Wheel, a stop pin rotating with the said wheel and co-acting with the end of the said stop-arm, a cut-off arm 10
