ALARM-CLOCK.
T 0 all whom it may concern:
Be it known that I, PAUL 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 Improvement in Alarm-Clocks; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-
Figure 1 a view in front elevation of a clock constructed in accordance with my invention with the upper portion of the dial broken away to show the clock-movement with particular reference to the switch for converting the clock from a long alarm to an intermittent alarm and vice versa, and to the switch for cutting out the alarm altogether. Fig. 2 a broken view of the clock in vertical central section, showing the clock adjusted for sounding a long alarm, and also showing the alarm as shut ofl. Fig. 3 a view of the clock partly in plan, and partly in horizontal section. Fig. 4: a detached View in side elevation of the case-body. Fig. 5 a View of the clock in side elevation with its ring-head and ring broken away. Fig. 6 a detached broken view in vertical central section through the case back and bell, with particular reference to showing the posts mounted in the rear plate of the clock-movement and extending through the case-back for the support of the bell and the brace or prop by means of which the completed clock is supported in an upright position.
My invention relates to an improvement in that class of alarm-clocks furnished with circular sheet-metal cases and concentric bells, the object being to produce a compact, convenient and reliable clock constructed with particular reference to the employment of large heavy bells without unduly thickening the clocks from front to rear, and to providing a sightly and convenient position and arrangement for the two switches by means of which the alarm is changed from a long to an intermittent alarm and vice versa, and by which the alarm is entirely out off.
With these ends in View my invention consists in a clock having certain details of Specification of Letters Patent.

Serial No. 586,264.
construction and combinations of parts as will be hereinafter described and pointed out in the claims.
In carrying out my invention as herein shown, I produce from a single piece of sheet-metal a circular case-body characterized by a convex closed, crowning circumferential hollow enlargement or band 2 merging at its rear edge into a rearwardly projecting closed case-back 3 and at its forward edge into a concentric bezel-ring flange 1 which is narrower than the back 8 which, so to speak, is shallower than the crowning band 2 forming the main or characteristic feature of the case, and, as shown, twice as wide as the said back 3 is deep. The band 2 aforesaid is bead-like or crowning in form and larger in diameter than the case-back 3 or the flange 4 and receive the ring-head 5 and ring 6, as well as the legs 7. The said band 2 also receives the alarm-switch 8 and the cut-off switch 9 which, as shown, are symmetrically arranged on either side of the ring-head 5 and slide circumferentially in the plane of the case.
The closed rearwardly projecting caseback 3 is formed in its side wall with a lateral bell hammer opening 10 through which the hammer-head 11 on the hammer-wire 12 strikes the inner face of the forward edge of the deep flange 13 of a large heavy concen trio bell 14: which, as shown, is attached by screws 15 on the opposite sides of but close to its center, to short posts 16 riveted in and close to the center of the rear movementplate 17 of the clock. The bell 14 is made enough larger in diameter than the said case-back 3 to form an annular clearance space 18 as seen in Fig. 8. In this space 18 the hammer-head 11 vibrates in striking the edge of the bell. Under this construction I avoid passing the hammer-wire 12 rearward through an opening in the back of the case as is usually done, and therefore secure a more direct action of the hammer upon the bell and save space from front to rear. The forward edge of the flange 18 of the bell 14; just clears the rounded rear face of the crowning band 2.
The clock-movement itself may be of any approved construction and will not therefore be illustrated or described further than called for by the immediate purposes of this present description. Its pillars 19 are passed through the edges of the case-back 3 to which the movement secured by nuts 20. Nuts 21 also screwed upon the rear ends of the pillars 19 secure the rear IHOVGIIIEHt-Pltll'O 17 to the said pillars and form a space 22 between the rear movement-plate 17 and the back 3.
A bezelring 23 sleeved over the bezel-ring flange at and secured thereto by screws 2i, holds the glass against the outer edge of the dial-mat 26 which rests upon the dial 27 which in turn is secured to the dial-back 28 which is formed with rearwardly extending fingers 29 resting upon the front-plate 20 in the usual manner.
The switch-hobs S and 9 are formed with inwardly extending stems 30 and 31 passing through slightly bowed switch-plates 32, and also through friction springs 33, the said plates and springs respectively bearing upon the outer and inner faces of the crowningband 2 of the case-body, the said band being formed with slots 34 to permit the sliding movement of the knobs. The said plates 32 are provided with the wording (not shown) necessary to indicate the functions of the re spective knobs 8 and S). The inner end of the stem 30 of the switch knob 8 engages with the upper end of an intermittent alarmlever hung upon an arbor 3G and provided with a coiled-spring 37 which exerts a eonstant effort to hold the finger 38 formed upon the lower or inner end of the lever in operative relation to the intermittent alarmcam 39 which is driven by the time-movement of the clock in the ordinary manner, and which, at regular intervals, lifts the lever 35 for the intermittent sounding of the alarm when the switch 8 is moved upward to the limit of its sliding movement so that its stem 30 clears the upper end of the lever as shown in Fig. 1. The alarm-train having been released by the lifting of the lever 35 by the wheel 39, is intermittently stopped by the engagement of a tooth 4:0 on the lever 35, by a pin .41 carried by the alarm-escape wheel 12 which is engaged in the usual manner by a verge 43 mounted upon a verge arbor 44 carrying the hammer-wire 12 afore said. The said arbor 4% also carries a bent wire 15 commonly known as the hammer tail. This wire 45 co-acts, in the usual manner, with a flat sheet metal alarm-camspring 46 which, when it is allowed to spring forward, releases the hammer-tail 45, and thus permits the vibration of the hammer. The extreme end of the wire 15 engages with the bent inner end of a stop-lever 17 hung upon an arbor 4:8 and having its upper end bentfor engagement by the stem 31 of the switch-knob 9. When the said knob 9 is at the limit of its upward sliding movement, as shown in Fig. 1, it has no effect upon the stop-lever 47. hen, however, the knob 9 shown in Fig. 2, its stem 31 engages with the stop-lever 17 and throws the same against the hammer-tail the vibration of which is thus prevented so that neither a long nor a short alarm may be sounded. By moving the switch-knob S from right to left, and therefore down ard, its stem 30 engages with the upper end of the lever 35 and throws the same into its retired position in which it is not operated upon by the camwheel 39 so that a long alarm will be sounded rather than an intermittent alarm. Other means than those shown might be employed for causing the switch-knobs S and 9 to act upon the movement so as to cut off the alarm altogether, or to convert it from an intermittent to a long alarm, and vice vcrsa, my invention consisting in particular, in this respect, in mounting the switch-knobs in the central band or crowning enlargement of the case-body and arranging them so as to he moved circumferentially over the same in one direction or the other in the plane of the case.
As shown, the clock is supported by the legs 7 aforesaid, and by means of a rearwardly extending sheet-metal prop or brace a9 held in place by the screws 15 employed to secure the bell 1a. to the posts 16, as shown in Figs. 3 and 5. The bell. 14f and the prop 49 are thus secured through the medium of the short posts 16 to the rear movementplate 17, rather than to the central portion of the relatively light sheet-metal caseback Fig. also shows the knurled button 50 by means of which the alarm is set, and the knurled button 51 by means of which the hour and minute hands are set.
I claim 1. In an alarm clock, the combination with a one-piece sheet-metal case-body comprising a crowning circumferential hollow band, a concentric rearwardly projecting closed case-back smaller in diameter and shallower than the said band and formed with a lateral bell-hannner opening, and a bezel-ring flange projecting forwardly from the forward edge of the said band and smaller in diameter than the same; of a clock-movement located within the said casebody, secured to the case-back thereof and provided with a hammer located adjacent to the said bell-hammer opening, a bell encircling the said case-back and extending forwardly over the same, its forward edge clearing the rounded rear portion of the said crowning band; and a bezel-ring secured to the said bezel-ring flange.
2. In an alarm clock, the combination with a case-body having a closed back made integral with it, of a concentrically arranged bell encircling the said back of the said case-body, a clock-movement located within is moved from left to right, and therefore i the said case-body and secured to the said downward into its operative position as case-back near the edges thereof, posts mounted in the rear movement-plate of the clock movement close to the center of the said plate and extending rearwardly thereform through the central portion of the caseback and through the bell which they support, and a brace or prop secured to the pro jecting rear ends of the said posts for assisting in supporting the clock in an upright position.
3. In an alarm clock, the combination with a one-piece sheet-metal casebody having a crowning hollow circumferential band formed in its periphery and on the opposite 1 sides of its apex with two switch-knob slots, a concentric rearwardly projecting closed case-back smaller in diameter and shallower than the said band and a bezel-ring flange extending forward from the forward edge of the said band and smaller in diameter than the same; of an alarm-movement located within the said case-body, two switchknobs respectively mounted in the said switch-knob slots and having circumferential sliding movement therein in the vertical plane of the said crowning band; and means for connecting the said switch-knobs with. parts of the alarm-movement.
4. In an alarm clock, the combination with a one-piece sheet-metal case-body having a crowning hollow circumferential band formed in its periphery with a switch-knob slot of an alarm-movement located within the said casebody and provided with a 11ammer and a hammer-tail, a stoplever mounted upon the said movement, and a switchknob mounted in the said switch-knob slot for circumferential movement therein in the plane of the said band and coacting with the outer end of the said stop-lever the inner end of which coacts with the said hammer-tail.
