WILSON E. PORTER, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO NEW HAVEN CLOCK 00., OF NEW HAVEN, CONNECTICUT,'A CORPORATION.
LEVER OR MARINE STRIKE CLOCK MOVEMENT.
4 Application filed March 12, 1915.
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 anduseful Improvement in Lever or Marine Strike Clock Movements; 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 rear elevation of a lever or marine strike clock-movement constructed in accordance with my invention. Fig. 2 a view thereof in front elevation. Fig. 3 a plan View of the movement as shown in Fig. 1, some parts being omitted for clearness. Fig. 4:311 underside view of the movement as shown in Fig. 2.
My invention relates to an improvement in lever or marine strike clock-movements, the object being to produce a compact, convenient and effective clock-movement characterized by having a rack-and-snail striking mechanism located to the rear of the rear movement-plate, the snail beingmounted upon a removable shaft driven directly from the socket or hour-wheel of the dialwork which is located in front of the front movement-plate.
With these ends in view, my invention consists in a lever or marine strike clockmovement having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claim. a
In carrying out my invention, as herein shown, I locate the snail 2 back of the rear movement-plate 3, mounting it upon the projecting rear end of a removable snailshaft 4 the forward end of which projects through the front movement-plate 5 and carries a removable snail-driving wheel 6 meshing directly into and driven by the socket or hour-wheel 7 which is mounted as usual upon the projecting forward end of the center-arbor 8, whereby the movement of the dial-work is transmitted directly from front to rear for the actuation of the snail 2 which is located, as described, back of the rear movement-plate.
One of the convenient features of the con- Specification of Letters Patent.
Patented Aug. 10, 1915.
Serial No. 13,983.
struction above described, is that after the movement has been put together, the snailshaft 4 may be inserted into its bearings after the application to it of either the snail 2 or the wheel 6, or both the snail and Wheel may be applied to it after the shaft has been inserted into its place in the plates 3 and 5. In dismounting the clock, either or both the snail 2 and wheel 6 may be removed from the shaft prior to its removal from the plates 3 and 5. To position the snail with respect to the dial-work, it is only necessary to move the socket-wheel 7 out of mesh with the snail-driving wheel 6 and remesh them in accordance with the given timing requirements.
The steps of the snail-2 are engaged by a pin 9 located in the outer end of a snailfinger 10 mounted upon a hub 11 turning upon a stud 12 and also mounting the arm 13 of the rack 14: the teeth of which are engaged by gathering-pins 15 set in a hub 16 mounted upon the projecting rear end of a strike-shaft 17 the rearend of which is journaled in the rear movement-plate 3 and the forward end of which is journaled in an intermediate movement-plate 18. The teeth of the rack 14 are also engaged, as usual, by a latch-pin 19 in a stop lever 20 hung upon a stud 21 and also carrying a stop-pin 22 extending inward through a clearanceslot 23 in the said rear movement-plate into position for engagement by a stop-pin 24: in the stop-wheel 25 of the strike-train which may be of any approved construction.
As herein shown, though this feature is not essential to my present invention, the center-arbor 8 is mounted at its forward end in a bridge 26 secured in place by screws 27 entering the rear movement-plate 3 which is formed with a large concentric clearanceopening 28 for the clearance of the center- Wheel mounted upon the center-arbor but not shown. It will be noted by reference to Fig. 2, that the balance-wheel 29 and hair-spring 30 are located between the front movement-plate 5 and the intermediate movement-plate 18. Virtuallythe main ele' ments of the striking mechanism are located to the rear of the rear movement-plate 3 where they are convenient for access and attention, and where they are much less crowded than if located adjacent to the time-train and dial-Work with which, however, the snail is directly connected by means of the snail-shaft 4 running from front to rear and directly driven by the hour or socket-wheel 7 of the dial-work which is located in front of the front movement-plate. I claim In a lever or marine strike clock-movement, the combination with the front and rear movement-plates thereof, of dial-work located in front of the front movementplate, rack-and-snail striking mechanism located to the rear of the rear movementplate, a removable snail-shaft mounted in the said plates so as to project forward of the forward plate and rearward of the rear plate and having the snail of the rack-andsnail striking mechanism mounted upon its rear end, and a snail-driving wheel mounted upon the front end of the said snail-driving shaft and meshing into and driven by the hour or socket-wheel of the dial-work.
In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
