Specification of Letters Patent.

Patented Mar, 10, 1914.

Application filed March 19, 1913. Serial No. 755,542.

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 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 a clock-movement constructed in accordance with my invention. Fig, 2 a reverse plan view thereof. Fig. 3 a detached view of the separately organized time-train movement of my improved clock. Fig. 4 a reverse plan view thereof. Fig. 5 a view thereof in rear elevation with the main wheel and the ratchet wheel shown by broken lines. Fig. 6 a broken sectional view on the line a-b of Fig. 2.

My invention relates to an improvement in clocks, the object being to greatly facilitate all of the adjusting operations through which a clock-movement must pass before it is put into its case.

With these ends in view my invention consists in a separately organized time-train movement having assembling-sleeves adapting it to be applied as one piece to the other parts of a clock-movement.

My invention further consists in certain details of 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 construct a separately organized or self-contained time-train movement adapted to be handled as one piece and designed to be assembled by itself and put through all of the necessary adjusting operations before it is associated with the other parts of the clock-movement. This self-contained timetrain movement (Fig. 4) consists of a circular front movement-plate 2 and a circular rear movement-plate 3 permanently connected by means of three hollow movement pillars 4 shouldered at both ends and riveted at their inner ends into the rear movement plate 3 and having their outer ends threaded for the reception of screws 5 passmg through the front movement-plate 2. The said pillars 4, though shown as hollow, may be solid, if preferred, Between the said front and rear movement plates 2 and 3, I permanently locate, as shown, three assembling-sleeves 6 having their opposite ends shouldered, whereby they are adapted to be set into suitable openings 7 in the said plates between which they are positioned, as shown in Fig. 3, with reference to the pillars 4, so that the sleeves 6 assist. in preventing the plates 2 and 3 from being sprung when the self-contained time-train movement is assembled with the power train movement which, as shown in the clock chosen for illustration, has only one movement plate, this being the rear movement plate 8. In place of having a separate front plate for the power-train movement the rear plate 3 of the time-train movement per forms that oflice. The said assembling sleeves 6, it will be understood, are permanently located between the plates 2 and 3 in which they are positioned prior to the insertion of the screws 5 into the pillars 4.

Between the plates. 2 and 3 I locate the several parts of a time-train of any approved constructlon and not shown herein except for the center-wheel 9, the centerpinion 10 and center-shaft 11, the projecting front end of which latter is furnished, as usual, with a cannon pinion 12 meshing into a dial-wheel 13 carrying a dial-pinion 14 perinanentlymounted upon a stud 15 in the plate 2. The said into a socket-wheel 16 on a socket 17 ordinarily set over the projecting end of the shaft 11 just before the hour and minute hands and dial (not shown) are applied. The parts omitted from the drawing include the third, and fourth wheels of the timetrain and the escapement device which includes the escapement wheel, the pallet or verge, and the balance-wheel, all of which parts are permanently located between the plates 2 and 3 when they are assembled. It will be understood that all of the parts described as being organized with the plates 2 and 3 are permanently connected therewith so that together they form a self-contained time-train movement assembled by itself and handled as one piece.

The clock herein shown and described being a front-winding clock, the separately dial-pinion 14 meshes organized time-train movement is provided, l to permit the intermediate wheel 30 on the as one of its permanent parts, with a winding arbor 18 mounted in the plates 2 and 3, having its projecting front end 19 squared and its rear end furnished with an auxiliary windingwheel 20 which forms a permanent part of the time-train movement and which meshes into the main winding or ratchet wheel 21 which is mounted upon the squared front end of an ordinary barrel-arbor 22 which terminates in a trunnion 23 having hearing, when the clock is assembled, in a hole 24 in the rear movement-plate 3 of the time-train. At its rear end, the barrel-arbor 22 is j ournaled in the single movementplate 8 of the power-train movement.

The power-train of my improved clock includes a barrel 25 mounted upon the said arbor 22 and furnished at its forward end with a main or barrel-wheel 26 meshing into an intermediate pinion 27 formed upon the shaft 28 the front end of which is journaled in a hole 29 in the front plate 2 of the timetrain movement. The said shaft 28 is furnished near its forward end with an intermediate wheel 30 which, when the clock is wholly assembled, meshes into the pinion 10 and drives the time-train. Now as the said shaft 28 with its pinion 27 and wheel. 30 is not permanently organized with the selfcontained time-train movement, I provide for the clearance of the said shaft 28 from the rear plate 3 of the time-train movement by forming an open clearance slot- 31 therein as shown in Figs. 3 and 5.

In the absence of a separate front plate for the power-train movement, I am obliged, in the construction shown, to provide the plate 3 upon its rear face with a stud 32 carrying a pawl 33 actuated by a spring 34, this pawl being located in position to act as a ratchet for the winding wheel 21 when the clock-movement is assembled. Three long assembling-pillars 35 are riveted at their rear ends (Fig. 6) into the single movement plate 8 of the power-train movement. In assembling the clock, long spacing sleeves 36 are set over these pillars and form bearings for the rear plate 3 of the separately organized time-train movement which is set over those portions of the pillars 35 projecting through the sleeves 36, the said projecting portions of the pillars 35 passing through the assembling sleeves 6 of the separately organized time-train movement as shown in Fig. 6.

When the separately organized time-train movement is brought to a bearing upon the outer ends of the spacing sleeves 36, the winding wheel 21 is meshed into the intermediate winding wheel 20 and the trunnion 23 of the arbor 22 entered into the hole 2-1 in the plate 3. Also, the projecting front end of the shaft 28 passes through the clearance slot 31 in the plate 3 in such a way as shaft 28 to be interposed between the plates 2 and 3 in position to mesh into the center pinion 10. Now when the separately organized time-train movement has been properly assembled with reference to the power-train movement, the short spaeingsleeves 37 are slipped over those portions of the assembling-pillars 35 which project through the front movement-plate 2 as shown in Fig. 6. The dial plate 38 is now set over the extreme front ends of the assembling-pillars 35 which project slightly through the short spacing sleeves 37 upon which the plate 38 rests. After this the screws 39 are passed through the dial-plate into the counterbored and threaded outer ends of the pillars 35, whereby the plates 8, 3, 2 and 38 are all drawn together and firmly seated upon the spacing sleeves 36, 6 and 37. However, the adjustment of the time-train is not disturbed by any pressure put upon the plates 2 and 3 which will not be sprung together by the screws 39, since the assembling-sleeves 6 which are located directly in line with the action of these screws form struts for preventing the plates 2 and 3 from being drawn together, and therefore the adjustment of the members of the separately organized time-train movement is not disturbed. It will be understood that the assemblingsleeves 6 which act as struts, will be spaced or distributed between the plates 2 and 3 so as to accomplish this result, but it is not essential that they should be regularly spaced or separated by equal distances. They will also be arranged as shown between the movement pillars at, but here again no exact spacing is necessary.

It should now be explained that the most delicate adjusting work called for is upon the escapement features of the time-train. Under my invention, the time-train includ ing its escapement features, is organized by itself as shown in particular in F ig. 4, so that they are readily accessible for adjustment without being in any way hampered by the other parts of the clock-movement. Therefore the escapement mechanism is completely adjusted and timed under the most favorable conditions of access before the separately organized time-train movement is assembled with the power train. This enables the adjustment of the escapement to be efi'ected with less labor and in a more perfect way than may be done in clocks as ordinarily constructed.

It must be understood that the principle herein disclosed of organizing the time train movement by itself is applicable to a considerable range of clock-movements and is not confined to the particular movement herein shown and described.

I claim 1. As a new article of manufacture, a

train,

separately organized self-contained timetrain movement having front and rear movement plates, pillars permanently located between and connecting the said plates, and assembling-sleeves permanently located between the said plates for which they form struts and adapted for the passage through them of assembling-pillars connected with a power train movement, whereby when pressure is applied to the plates of the time-train movement in associating it with a power-train movement, the said plates are prevented from being sprung by the said sleeves.

2. In a separately organized self-contained time-train movement, the combination with front and rear movement plates mounting the several members of a timeof pillars interposed bet-ween and permanently connecting the said plates, and assembling-sleeves interposed between and permanently located between the said plates and distributed between the said pillars and acting as struts for the support of the movement plates and receiving assemblingpillars connected with a p0wer-train movement whereby when pressure is applied to the plates in associating the said time-train movement with a power-train movement the said plates are prevented from being sprung by the said sleeves.
