Application filed June 10. 1912. Serial I i-o.
To all whom it may concern:
Be it known that 1. Mason E. PORTER, a citizen of the United States, residing at New lilaven, in the county of New Haven and State of Connecticut, have invented a new and useful improvement in Clocks; and do hereby declare the following, when taken in connection with the accompanying dij'awings and the characters of reference marked thereon, to be a full, clear, and exact descrip 'tion of the same, and which said drawings constitute part of this application, and represent, in
Figure l a view in front elevation of a clock constructed in accordance with my in vention. Fig. 2 a view in front elevation of the clock-move1neut as it appears when removed from the case, and drawn on an enlarged scale. In this view the rack is shown in its normal position. Fig. 3 a correspond ing view showing the rack dropped ready for the clock to begin to strik eleven p. m., and the lifting-lever just about to drop elt the nose of the cam. Fig. i a broken view of the movement in front elevation with the dial-work removed, and with the remaining parts corresponding in position to their positions in Fig. 2. Fig. 5 a similar view with the parts corresponding in position to their positions in Fig. 3. Fig. 6 a detached view in front elevation of the warn-lever and lif ing-lever which act as one piece. Fig. 7 a plan view thereof. Fig. 8 a detached perspective view of the stop-lever. Fi 9 a plan view of the rack and its rack-arm.
My invention relates to an improvement in that class of clocks known to the trade as Elk clocks, for the reason that they are constructed with special reference to striking only once in twenty-four hours, and that at eleven p. m., the object being to provide at a low cost a simple, durable and reliable clock of the character described.
VJith these ends in view, my invention consists in an Elk clock having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claim.
In carrying out my invention as herein shown, I employ a twenty-four hour wheel 2 which is mounted upon a stud 8 riveted so as to project from the outer face of the front movement-plate e of the clock, the said wheel being furnished with a twenty-tour hour cam 5, and held in place by a screw 6 enter- Specification of Letters Patent.
Patented Sept. 3, 1912.
.ing the stud purpose. ,he s I and driven by a m hou mounted upon an hour-hand FOClZ'tiit- S which carries hour-wheel meshed into and pinion it) on a dial-wheel ll which drn'en by a cannon-pinion 12, the parts described being of ordinary con struction and arraiigcinent cxccot the Monty-tour hour wheel 2, the "twenty-four -our cam 5 and the specs! twelve-hour wheel i Riding upon the the twenty-four hour cantl 5 is a fen Ring-arm l3 having its extreme outer end bent inward at a right angle and beveled as to permit the wheel and cam 53 to be turned back in setting the clock without de 'an ing the strike n'iechanisni. The said arl'n 13 is rigidly secured to the outer end of the hub of a warn-lever arranged horizontally in trout of the said front moveme t-plate 41-, and swinging upon stud. 16 mounted there in. A spring 17 coiled upon the hub 14- and respectively a tached at its ends to the warnlever 15, and the plate 4-, exerts a constant effort to swing the said linger 13 and lever 15 from left to rightdownward.
l- 'frt its right hand end the warnlevcr 1.5 is turned inward to form a warn-linger 18 extending through a clearance-opening 4: in the front movement-plate and co-acting with a warn-pin 19 mounted in the warn-pin wheel 20 of the striketrain. At its right hand end the said warn-lever l5 is also formed with a depending arm 21. bent forward at its lower end to term a lifting-finger 22 which co-acts with a bevel 23 upon the lower edge of a stop-lever 2:: pivotally hung by its lower end upon a stud 25 in the plate 4, a helical spring 243 being provided for exerting a constant ett'ort to swing the said lever from right to left. At its upper end, the stop-lever 2%. is termed with stop-linger 2. extending t idfu ing-pin arbor 32 of the strike-train. The said rack 29 is located at the outer end of a rack-arm 33 hung upon a stud 3e mounted in the front movement-plat l, the said rack-arm 33 being furnished with a spring 36 exerting a constant effort to swing the rack downward. A rack-stop pin 3'7 is located in the front movementplate at in position to be engaged by the lower end of the rack 29 when the same is dropped sutliciently to bring into action eleven of the teeth on the rack 29 so that the clock will strike eleven at eleven oclock in the evening. As shown, though this is not necessary, the clock is provided with a repeating plunger 38 mounted in brackets and engaging at its lower end with an operatingpin l-O carried by the outer end. of the warnlever 15, so that when the plunger is depressed against the tension of its spring 4.1, the rack will. be allowed to fall and the strike mechanism let off in the usual manner of repeatii'ig clocks.
already explained, niy improved clock is designed to strike eleven at eleven oclock in the evening and at no other time du the twentv-tour hours of the day. Nornially the stop-pin l?) in the stop-pin wheel 520 is engaged with the upper taco of the stop-linger of the stop-lever 2 However, as eleven oclock p. in. approaches, the cam raises the lifting-lever and hence the warn-lever 15, the lilting-linger 22 of which engages with the beveled edge 23 ot the stop lever Li and swings the same from left to right, whereby the ;top-linger of the stop-lever 1e; and swings the same from out from under the pin 1'5), thus allowing the stop-pin wheel 20 to move tar enough to engage the stop-pin it with the inner face oi the warniinger 18 ot the warn-lever 15. lin connnon parlance the clock is now on the warn and ready to strike. At about this time, the rack-retaining pin is moved by the swing the lever 29 from lelit to right out of engagementwith the teeth of the rack 29 which innnediately falls or swings downward under the influence of the rack-spring as until it is stopped by the engagement of its lower end with the 1; ck-stop pin 37. This downward movement Oi the rack may take place before or after the clock warned, this be ing innnaterial and depending upon the way in which the clock is timed as to warning and the dropping out the rack. Just at eleven oclock, the end of the lifting-lever 12 drops oil the high point of the cam 5 and permits the warn-lever 15 to fall, whereby its linger 18 will he carried below the range of the stop-pin 19, leaving the strike-train tree to start the revolution of the gathering hub 31, the gathering pin 30 of which will now lift the rack step-by-step as the clock strikes from 1 to 11, the stop-lever 24: being all this time prevented from swinging from right to left suiiiciently to bring its inger 27 under the pin 19, by the engagement of the rackretaining pin 28 with those pmrtions of the rack lying between the teeth thereof. as the clock strikes eleven, the pin 28 moves under the lower end of the rack as shown in Fig. l, permitting the stop-lever to be swung sulliciently from left to right to bring its finger 327' into the path of the pin 19 which engages with it and stops the strike-train. At the end of the striking operation, the clock may be said to have returned to its normal position in which it remains from twenty-three hours or more, when the cycle of operations above detailed will be repeated.
1 claiin.:
in a clock striking once in twenty-four hours, the combination with a twenty-tour hour wheel, of a twenty-tour hour cain carried. thereby, means for rotating the said whee and cam once in twenty-tour hours, a hitting lever engaging with the said earn, a \VLH'DdGVGl' mounted with the said liftinglever and operated thereby, and provided with a warndinger and a lifting finger, a stop-pin wheel carrying a stop-pin co-acting with the warn-linger of the \Vttl'n-lS'VGl, a pivotal stop-lever provided with a stoplinger co-acting with the said stop-pin, with a racleretaining pin and adapted to be operated by the lit'tingdinger oil the warnlever, a rack the teeth of which co-act with the said rack-retaining pin, a gathering huh, a gathering-pin co-acting with the rack, and a raclestop pin located in position to :11 est the falling of the rack when a predetermined number of rack teeth have been presented to the action of the gatheringpin.
