CHIME-CLOCK.

Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed October 17,1917. Serial No. 197,150.

To all whom it may concern:

Be it known that I, WILSON E. PORTER, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Chime-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 is a view in front elevation of a self-contained time, strike and chime clockmovement constructed in accordance with my invention, the dial-work of the timemechanism and the rack-and-snail features of the strike-mechanism being omitted.

My invention relates to an improved chime clock, and is particularly adapted for incorporation in clock-movements of the marine type though not so limited, the object being to produce a reliable, relatively simple, self-contained chime clock-movement constructed with particular reference to compactness of form, and to the reduction of the number of parts to the minimum.

With these ends in view, my invention consists in a self-contained chime clockmovement comprising a time-train, a chimetrain and a strike-train constructed arranged and connected so that the chimemechanism is instantaneously released periodically by the time-mechanism without warning the former, whereby the use of warning mechanism for the chime-train is dispensed with.

My invention further consists in a selfcontained chime clock-movement having certain details of construction and combinations of parts, as will be hereinafter described and pointed out in the claims.

The prime characteristic of my improved self-contained clock-movement is the periodic instantaneous release of the chimetrain by the time-mechanism without the employment of the usual warning mechanism, whereby I simplify the clock-move- I ment to that important extent, both as to operation and number of parts.

In carrying out my invention as herein shown, I employ a releasing-lever 2 which is located, together with the parts with which it co acts, in front of the front movementplate 3, which mounts the forwardly projecting stud 4 on which the said lever oscil- 1ates.- At its lower end, the lever is formed with an arm 5 for the attachment of a helical operating spring 6 the upper end of which is fastened to an adjustable arm 7 held in place by a screw 8 entering the plate 3, the said spring being regulated in tension so as to snap the lever from right to left with the force required for the operation of the counter-weighted lifting-dog 9. A stoppin 10 mounted in the plate 3, limits the throw of the lever 2 from right to left. The

ally swing the lever 2 from left to right against the tension of its spring 6. When, in this movement, any one of the pins 12 passes the point 16 at the lower end of the face 11, the lever 2 is snapped, so to speak, from right to left by the action of its spring 6 aforesaid for the operation of the dog 9 as will be more fully described hereinafter. The said lever 2 is formed with a turnback bevel 17 over which the pins 12 ride, when the wheel 13 is turned counter-clock wise, with the effect of camming the entire upper portion of the lever rearward sufficiently to let the pin ride over it, this idle movement of the lever being permitted by the reduction of its lower end in thickness, as at 18. When, therefore, the disk 18 is turned counter-clockwise in setting the clock, the pins 12 ride idly over the lever without moving it counter-clockwise, leaving it in its normal position of engagement with the stop-pin 10. At its upper end the lever 2 is formed with a beveled finger 19 which co-acts with the beveled tooth 20 of the counter-weighted lifting-dog 9 which is hung by a headed stud 21 upon the hori- V face 11 of'the lever 2, successively push the same from left to right against the tension of its spring 6. 'During this time the straight edge of the finger 19 engages with the edge. of the tooth 20 of the dog 9 and turns the dog on its stud 21 against the counter-Weighted end of the dog, whereby the finger 19. passes under the nose 20 of the dog so as to be shifted from the left to the right hand side of the'said tooth, the dog now dropping back into its'normal position with the beveled edge of its tooth in opposition to the beveled edge of the finger 19.

Now at the termination of the quarter hour,

the active pin 12 having moved the lever 2 into its blow delivering position passes the point 16 at the lower end of the face 11, permitting the spring to act and snap the lever by a quick movement from right to left dun ing which movement the beveled edge of its finger 19 engages with the beveled edge of the tooth 20, and bodily lifts the dog 9, and with it the lifting lever 22, and in turn the stop-lever 25, the lower edge of which rests upon an integral rounded bearing surface 26 extending upward from near the free end of the lever 2 V The outer end of the said stop-lever 25 mounts a stop-pin 27 projecting rearwardly' through a slot 28 in the movement-plate 3 into position to engage with a shockabsorbing finger 29.riveted to the fly 30 of the chime-train which may be of any approved construction and arrangement, and does not, therefore, require detailed illustration or description. So far as shown, it consists of an'arbor 31 amounting the fly 30, a pinion 32 forming apart of the said arbor and meshing into a chime-wheel 33 on an arbor 3 1 furnished with a pinion 35 meshing into another wheel of the chime-train. The lifting-of the stop-lever 25 in the manner described, thus instantaneously releases the chime-train, the lifting of this lever having been effected, as described, through the medium of the counter-weighted dog 9, the spring-actuated releasing-lever 2, the liftinglever 22 and the stop-lever 25, which parts take the place of the warning mechanism ordinarily employed for warning the chime-train. V

The'lifting-lever 22 is formed with a hub '36 bywhich it is mounted upon the projecting forward end. of an arbor-37 journaled in the front movement-plate 3' and in the complementary rear movementeplate 38, and carrying upon itsprojectlng rear end, a

' plementary sustaining-'clisk42, which form no part of my presentinvention. The said count-wheel 11 is carried by a hub 43 also carrying a wheel 44: and mounted upon the projecting rear end'of an arbor 45,'driven by the chime-train. The said wheel a4:

meshes into a, wheel 46 at the inner end of the chime drum 47, the pins 48 of which engage with lifting fingers 49 depending from hammer-plates 5O pivotally mounted upon a horizontal stud 51 supported at its inner end in the rear movement-plate 38 and at its cerned with the chime, strikean'd time-trains" which I'have deemed it unnecessary to illus trate and describe in detail, but which are sufficiently indicated by the chime-train main wheel 60 and winding arbor 61, the

timetrain main wheel 62 and winding arbor 63, and the'striketrain main wheel 64 and winding arbor 65. V

"In the operation ofmy improved clock,

the quarter hour pins 12 acting through the V releasing lever 2 coiu ter-weighted lifting dog '9, liftlng lever 22, and stop-lever 25,

release the chime-train every quarter hour through its fiy, withoutwarning the chimetrain as the term warning is understood in this art. The chimes are sounded on the quarter hours, and at the conclusion of the fourth quarter which will be on the hour, the

chiming mechanism is caused'to release the" strike-train by suitable mechanism forming no part of my present invention and not shown or described. The term" self-0on tained as used" by me in the foregoing description and in the appended claims to characterize my improved clock in'ovement, is employed in the sense of a cloclnmov'ement in which the time, strike and chime-trains are all organized together on and between the same movement-plates, whereby I not only secure compactness of form, but also avoid the objections incident to and inseparable from the common separately organizedtime and chime mechanisms cooperably related by parts reaching from one to the other. When such independently organized mechanisms are independently mounted in a wooden clock-case the slightest warping of the same will result either in the failure of the two mechanisms to function properly or not at all. Moreover, when the time and chime mechanisms are independently organized, the parts connecting them for their cooperation, are necessarily long and springy and are therefore not only unreliable even when perfectly adjusted, but also are liable to become bent or displaced ori'otherwise deranged. I am aware, however, that a self-contained clock-movement in which the chime and strike trains are organized on and between the same movement-plates is not broadly new. I do not therefore claim such a construction broadly, but only my particular self-contained time, strike and chime-movemcnt characterized by the non-warning release of the chime-train.

I claim 1. In a self-contained time, strike and chime clock-movement, the combination with the time and chime mechanism thereof, of a spring-actuated releasing-lever periodically moved by the time-train into its blow-delivering position, and a lifting-dog operated by a blow delivered by the said releasing lever for releasing the chime-train without warning the same.

2. In a self-contained time, strike and chime clock-movement, the combination with the time and chime mechanisms thereof, of a spring-actuated releasing lever periodically moved by the time-train into its blow delivering position, a liftingdog operated by a blow delivered by the said lever when the same is released by the time-train, a liftinglever mounting the said dog, and a stoplever operated by the said lifting-lever and directly cooperating with the chime-train for releasing the same without warning.

3. In a self-contained time, strike and chime clock-movement, the combination with the time and chime mechanisms thereof, of a spring-actuated releasing-lever periodically moved by the time-train into its blow-delivering position, a lifting-dog operated by a blow delivered the said lever when the same is released by the time-train, a liftinglever mounting the said dog, a stop-lever operated by the said lifting-lever and di rectly cooperating with the fly of the chimetrain for releasing the said chime-train without warning the same.

4. In a self-contained chime clock, the combination with the time and chime trains thereof, of a chime-disk mounting chimepins, a. releasing-lever having an operatingface whereby the lever is operated by the said pins, and with a beveled turn-back fac'e whereby the lever is pushed into a clearance position by the said pins in turning back the clock in setting, the said lever being periodically moved into its blow-delivering position by the time-train, a lifting dog operated by a blow delivered by the said releasing-lever, a liftin -1ever mounting the said dog, and a stopever operated by the said 1i fting-lever and co-acting with a member of the chime-train for releasing the same without warning.

5. In a self-contained chime-clock, the combination with the time and chime-trains thereof, of a releasing-lever periodically moved into its blow-delivering position by the said time-train and formed with a beveled operating-finger, a counter-weighted lifting-dog formed with a beveled tooth for co acting with the said beveled finger, whereby the dog is idly operated when the lever is moved in one direction and actively operated when the lever springing in the opposite direction, delivers a blow upon it, a lifting-lever mounting the said dog, and a stop-lever lifted by the lifting-lever and directly co-acting with the chime-train for releasing the same without warning.

In testimony whereof, I have signed this specification in the presence of two subscrib ing witnesses.
