WATCH-MOVEMENT PLATE.

SPECIFICATION forming part of Letters Patent No. 364,110, dated May 31, 1887.

Application filed September 6, 1886. Serial No. 212,833.

To all whom it may concern:

- Be it known that I, GEORGE E. HART, of WVaterbury, in the county of New Haven, and in the State of Connecticut, have invented cer tain new and useful Improvements in Watches; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference bei n g had to the accompanying drawings, in which- Figure 1 is a perspective view of the sections of my movement-plate separated from each other. section, having in place the balance-jewel, regulator-arm, and winding-wheels. Fig. 3 is a perspective view of the sections when combined. Fig. 4 is a like View of the plate in position within a watch, and Fig. 5 is a section of the same upon line x 90 of Fig. 3.

Letters of like name and kind refer to like parts in each of the'figures.

The object of my invention is to enable the balance-jewel, regulator, and winding-wheels of a watch to be easily secured in or removed from position; and to this end said invention consists, principally, as an improvement in watches, in a movement-plate composed of two flat sections which are adapted to be secured together with their inner faces in contact, in combination with ,each other and with a regulator that is pivoted between and projects from said sections, substantially as and for the purpose hereinafter specified.

It consists, further, as animprovement in watches, in a movement-plate which is com posed of two superimposed separable sections, in combination with each other and with a regulator-arm and a balance-jewel that are placed between the sections and are held in place by the means employed for securing said sections together, substantially as and for the purpose hereinafter shown.

It consists, further, as an improvement in watches, in a movement'plate which is com posed of two superimposed separable sections, in combination with each other and with a regulator that is pivoted at one end between said sections, and at its opposite outer end is adapted to be moved over a scale which is formed upon the inner section, substantially as and for the purpose hereinafter set forth.

Fig. 2 is a like view of the inner (No in odcl.)

It consists, further, as an improvement in watches, in a movement-plate which is composed of two superimposed separable sections, in combination with a regulator which has one end pivoted between said sections and its opposite outer end contained within a recess that is formed in the outer section and adapted to be moved over a scale which is provided upon the inner section, substantially as and for the purpose hereinafter shown and described.

It consists, finally, as an improvement in watches, in a movementplate which is composed of two superimposed separable sections that are adapted to contain between their inner faces and to hold in operative position therein a regulator arm, a balance jewel, and winding-wheels, in combination with said parts and with means for securing said sections together, substantially as and for the purpose hereinafter specified.

In the carrying of' my invention into practice I cut by dies or construct in other ways two fiat plates, A and A, which have the same size and shape of outline, and in such respect correspond to a movement-plate of usual construction when made for the movement for which said sections are designed.

The sections A and A are provided with coinciding openings a near their peripheries, which fit over the reduced ends of movement-pillars B, and enable said sections to be held in relative lateral position and to be secured together and in place upon said pillars, for which purpose a screw, C, is passed downward into a threaded opening in each pillar, with its head extending over and bearing upon the outer face of the outer section, A. If desired, other means may be employed for securing said sections together, the principle being the same whatever fastening devices are used.

At suitable points within the outer face of the inner section, A, are provided recesses a, a and ad, for the reception of a mainspring-arbor winding-wheel, D, intermediate wheel, E, and winding-click F, which parts are contained therein, and are covered and held in place by the outer section, A. While said recesses are preferably formed entirely within said inner section, they may, if desired, be partly formed within the same and in part within said outer section.

The inner section, A, contains the usual pivot-openings, a, and any or all of the same may be jeweled, if desired, in which event each jewel is placed within a suitable recess in said section, and is held in place by the outer sec tion, A. The balance-jewel G, set in a metal bushing, y, is thus arranged at a suitable point, and upon oraround said bushing is pivoted one end ot'a regulator-arm, 1-1. As said bushing projects above said inner section, and said regulator-arm is wholly above the same, said outer section is provided within its inner face with a recess, a, for their reception. As thus arranged, said jewel and regulator-arm are held in place by said outer section, and are free to be removed or replaced when said section is re moved.

The regulator arm II extends laterally over a scale, a, which is provided upon the onterlacc of the inner section, A; and in order that said scale and arm may be seen and the latter rendered accessible, a suitable opening, a is out directly over the same in the outer section, A.

By means of the constructionshown the wi ndirigwvheels, click, regulator, and jewels are socurely held in place, while readily accessible, and either or all of the same may be easily and quickly removed or replaced whenever necessary for the purpose of cleaning or repairs.

Having thus described my invention, what I claim is- 1. As an improvement in watches, a movement-plate composed ottwo llatsections, which are adapted to be secured together with their inner faces in contact, in combination with each other and with a regulator that is pivoted between and projects from said sections, substantially as and for the purpose specified.

2. As an improvement in watches, a move ment-plate which is composed of two super imposed separable sections, in combination with each other and with a regulator-arm and a balancejewel that are placed between the sections, and are held in place by the means employed for securing said sections together, substantially as and for the purpose shown.

3. As an improvement in watches, a movement-plate which is composed of two superimposed separable sections, in combination with each other and with a regulator that is pivoted at one end between said sections, and at its opposite outer end is adapted to be moved over a scale which is formed upon the inner section, substantially as and for the purpose set forth.

4. As an improvement in watches, a move ment-plate which is composed of two superimposed separable seetions, in combination with each other and with a regulator which has one end pivoted between said sections and its opposite outer end contained within a re cess that is formed in the outer section and adapted to be moved overascale which is provided upon the inner section, substantially as and for the purpose shown and described.

5. .As an improvement in watches, a movement-plate which is composed of two superimposed separable sections that are adapted to contain between their inner faces and to hold in operative position therein a regulatorarm, a balance-jewel, and winding-wheels, in combination with said parts and with means for securing saidsections together, substantially as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this 11th day of August, 1886.

GEORGE E. HART.
