To all whomc't may concern: I

Be it known that I, ELMER E. STOCKTON, a citizen of the United States, residing at Bristol, in the county of Hartford and State of Connecticut, have inventeda new and useful Improvement in Alarm-Clocks; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon,'to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

Figure 1 a View in front elevation of an alarm-clock constructed in accordance with my invention, with its case in vertical section. Fig. 2 a corresponding plan view with the case and the bell in transverse section. Fig. 3 a detached view of the movement in side elevation; Fig. 4 a View of the clock in rear elevation, with the case shown in vertical section. Fig. 5 a reverse plan view of the movement as removed from the case. I

My invention relates to an improvement in that class of small alarm-clocks known to the trade as nickel alarms from having been originally supplied to the trade in cylindrical nickeled cases. The bells of these clocks have been variously arranged. The early practice was to mount the bell upon a bell-post rising from the center of the top of the case, and to strike it by ahammer the tail of whichwibrated in a slot formed in the top of the case; but clocks with their bells so located were objectionable for the reason that in this exposed position the bell was apt to be displaced with reference to the bell-hammer by the canting of the bell-post. Another objection to these clocks was, that the location of the bell in this position called for a large pastebo-ard packing box of special construction. Other clocks of the type had their bells arranged centrally belowt their cases, between their legs, or in a supplemental base. Nickel alarm-clocks with their bells arranged above and below their cases were succeeded by clocks having large bells arranged concentrically at the back of their cases, outside of the same and perforated for the passage of the winding and setting arbors of the clock. Clocks having these large bells, required the use of long windii'ig and setting arbors and special packing boxes, all entailing extra expense. Furthermore the bells being exposed had to be finished to correspond to the exterior finish of the cases, involving extra expense. Clocks having large concentric bells at the back on the outside of their cases, were followed by clocks having concentric bells located within the r cases, either in front or at the rear of their movements. These large concentrically arranged bells, whether placed inside or outside of the case, are expensive, and necessitate the making of cases of extra depth from front to rear.

The object of my present invention is to 1 overcome the objections above recited and produce a nickel alarm-clock adapted by its construction and arrangement of parts to have its bell located within its case without, however, enlarging the same for the purpose, and in such position to secure the best results from the bell-hammer.

With these ends in view, my invention consists in an alarm-clock having certain details of construction and arrangements of parts as will be hereinafter described and pointed out in the claims. 7

In carrying out my invention as herein shown, I locate the bell 2 in the space 3 between the righthand edges of the front and rear movement plates 4 and 5, and the right hand portion of the circular sheet metal band 6 of the cylindrical clock-case. The bell 2 is located edgewise in the space 3 so as to extend, as it were, from front to rear at a right angle to the plane of the movement-plates and parallel with the band 6 of the clock-case. The bell is located entirely outside of the movement, and, as shown, opens inward so that its edge is adjacent to the movement, and therefore in the most advantageous position for cooperation with the striking mechanism thereof, as will be explained later on. As thus arranged, the said bell 2 is located directly opposite the main time-wheel 7 and main time-spring 8, these parts of the time-train of the clock-move ment projecting into the space 9 between the left hand edges of the said front and rear movement-plates l and 5, and the left hand portion of the band 6. If desired, however, this arrangement might be reversed, and the bell 2 located at the left hand of the movement, and the wheel 7 and spring 8 located at the right hand of the movement. Under either arrangement it will be observed that the spaces 3 and 9 respectively located between the vertical edges of the movementplates 1- and and the sides of the band (5 of the case, are measurably utilized. The corresponding space 10 between the bottom edges of the plates 4 and 5. and the bottom portion of the band (3, is reserved for the projecting portion of the ba1ance-wheel 11 and its spring 12. the said wheel and spring being protected in this position by the heavy wrought metal brackets 13 riveted at their upper ends to the projecting front ends of the pillars 11 joining the lower ends of the front and rear movement plates 4: and 5. These brackets stitfen the band 6 and re ceive the threaded inner ends of the turned peg-like feet 15 which support the case and which are so close together as to make the base 6 relatively stilf between them, and therefore protective of the balance-wheel 11 and spring 12, the most delicate parts of the clock-structure. The balance-wheel staff 16 is pointed at its ends to form pivots which run in screw-studs 17 mounted in the lower edges of the plates 5 and 6 as clearly shown in Fig. 4. v

The space 18 bet ween the upper edges of the plates 1 and 5 and the upper portion or top of the band 6 is occupied by the projecting portions of the alarm crown wheel 19, the alarm verge 20, the alarm main wheel 21, the alarm main spring 22, and by the hammer tail 23 which extends horizontally over the movement from left to right, or from right to left according to the arrangementof the alarm bell 2 in the space or in the space 9 as the case may be. As shown, the hammer-tail extends from left to right, its left hand end being secured to the verge-arbor 24, and its right hand end being provided with a hammer 25 located close to the top of the hell 2. In this connection, I must point out that by arranging the bell in the vertical plane on one side or other of the movement, the bell-hammer is aided by gravity in striking it, whereby far better re sults are secured than when the bell-hammer must be operated in opposition to gravity.

The horizontal arrangement of the hammer-tail 23 as described. brings it into con venient position for its being operated upon directly for stopping the alarm by means of a vertically arranged plunger 26 the lower end of which engages directly with the upper edge of the hammer-tail 23 at a point toward the left hand end thereof. The said plunger 26 is mounted in a ring-head 27 rovided. as shown. with an angular rin 28. the upper end of the plunger being provided with a push-button in the form of a ball 29 located within and protected by the said ring 28. At its lower end the ringhead 27 has a concentric threaded stem 30 adapting it to be mounted in the horizontally arranged forwardly projecting upper arm of :1V wrought metal bracket ll corresponding to the brackets 13 before mentioned. and having its lower end fastened to the upper reach of the front movementplate 3 by a rivet 32. The horizontal upper arm of this bracket 31 tits snugly within the extreme upper portion of the band 5 and rigidly supports the same. The said plunger 26 is controlled in position by a leaf spring 3 the forward edge of which is notched to receive the lower end of the plunger and the rear end of which is secured by a rivet 34 to the lower face of the forwardly projecting arm of the bracket 31, as clearly shown in Fig. 3. It will thus be seen-that the upper space 18, which is the space between the' upper edges of the plates 4 and 5 and the upper portion of the band 5, is also utilized for the reception of tlre hammer-tail 23. the lower portion of the plunger 26, the spring 22, and portions of the bracket 31.

Under the described construction and arrangement of parts. I have so utilized the spaces between. the edges of the movement plates of the clock-movement and the band of the clock-case as to provide for the location of the hell 2 within the case without enlarging the case either as to diameter or as to depth-and at the same time to so locate, the hell 2 as to utilize the action of gravity in the operation of the bell-hammer 25, and also to locate the hammer-tail where it may be operated upon directly for stopping the alarm by means of a plunger 26 mounted in the ringhead '27.

As herein shown. the bell 2 is secured by a rivet 34 to the projecting outerend of a curved arm 35 formed upon the outer edge of a sheet-metal bracket ill) superimposed upon the rear movement-plate 5 and secured by nuts 37 to the threaded. projecting rear ends of the pillars l4 and 39 employed for holding the movement-plates "t and 5 together. It will be noticed that. the hell 2 receives the projecting portion of the third wheel 40 of the time-train which may be of any approved constriu-tion. and therefore not necessary to show or describe in detail in order to secure an understanding fof my present invention. It will also benoticed that the bell 2 takes advantage of the depth of the case from front to reaiprojecting considerably beyond the faces of the front and rear movement plates 4 and I claim 1. In an alarm-clock. with a case having a circular sheet-metal the combination band, of a time-alarm movement located within the said band in position to form an upper space, a lower space, and two side spaces, respectively situated between the said band and the edges of the movementplates, and a bell located in one of the said side spaces at a point entirely outside of the movement, with its open side inward and extending edgewise from front to rear across the planes of both of the said plates at a right angle thereto, the hammer-tail of the said time alarm movement being arranged horizontally in the said upper space and terminating in a hammer located directly over the upper edge of the said inwardly opening bell.
