ARTHUR JUNGHANS, OF SCHRAMBERG, \VURTEll'lBERG, GERMANY.
REGULATOR FOR TIME-PIECES.
SPECIFICATION forming part of Letters Patent No. 320,562, dated June 23, 1885.
Application filed February 19,1885. (No model.) Patented in Germany December 11, 1884, No. 31,612; in France December 18, 1884, No. 165,997, and in England January 12, 1885, No. 418.
T 0 all whom it may concern.-
Be it known that I, ARTHUR JUNGHANs, of Schramberg, in the Kingdom of \Viirtemberg, in the Empire of Germany, have invented certain new and useful Improvements in Devices for Regulating the BalanceSprings of Time-Pieces, (for which Letters Patent heretofore have been granted to me by the Government. of Germany, dated December 11, 1884, No. 31,642; England, dated January 12, 1885, No. 418, and France, dated December 18, 1884, No. 165,997,) of which the following is a specification.
The object of the invention is to produce a simple device for regulating the balance or hair springs of time-pieces, by which said springs may be quickly and easily inserted without injury to the springs, and by which the difference-in the running may be regulated within wide limits without elongating or cutting the springs, or without taking the movements out of the case; and the invention consists of certain details of construction, which will be more fully described hereinafter, and finally be pointed out in the claims.
In the accompanying drawings, Figure 1 represents a front view, partly in section, of my improved regulating device for the balance-springs of time-pieces. Fig. 2 is a side view; Fig. 3, a plan; and Figs. 4, 5, and 6 are details of parts of the regulating device.
Similar letters of reference indicate corresponding parts.
In the drawings, A represents one of the supportingplates of a clock or other timepiece, through which passes a spindle, i, which is guided in a sleeve, t, of the plate A. The front end of the spindle t, which projects through the dial-plate, is made square for applying thereto a key for turning the spindle, and also a crank, 70, which turns with the spindle i, as will be described more fully hereinafter. On the sleeve 43 is mounted a camplate, 9, the periphery of which correspondsto the spiral windings of the balance-sprin athat is to say, it has the same pitch as the latter. To a wing or extension, 9, of the camplate 9 is pivoted a crank, 72, which carries in a socket a split pillar, e, the outer end of which is made of conical shape. The pillar a can be turned on its axis in the socket of the crank h, and serves to clamp the balancespring a by means of a ring, f, that slides along the conical end of the pillar a, so as to compress the split ends of the same. Sometimes it is necessary to cut or break off a portion of the spring a, even to the extent. of one or more windings, for the purpose of giving the proper degree of tension to the remainder of the spring a. Herctofore a fixed pillar was used for holding the spring, which required the bending of the spring after each cutting off operation by means of a pair of pliers, so as to make it true and bring it back to the proper diameter for extending to the pillar. By my construction the bending of the spring a and its detrimental effects is entirely avoided, as the pillar 0 can be turned in its socket and moved nearer to or farther away from the center of the spring a by simply turning the crank h. The position of the spring a in a plane vertical with the axis of the balance-wheel is regulated by shifting the spring backward or forward between the split portion of the pillar e, and securing it then in position by the clamping-ring f. "When the position of the spring has been adjusted with reference to the escapcment-lever, and the escapement should still be out of boat, the cam-plate g is turned to the right or left, as required, after which the cam-plate g is se cured in position by a setscrew, m, that passes through the plate A, as shown in Figs. 2 and 3.
For regulating considerable irregularities in the running of the time-piece a crank, k, and spring 1?, ot'peculiar construction, are made use of. The crank it is keyed to the rear end of the spindle t, back of the cam-plate g, and turned by a key applied to the square front end of the spindle. The bent spring (1 is attached to the crank. 75, and provided at its outer end with a slot, p, and alinger, g, which latter slides along the circumference of the cam-plate g, and guides thereby the slot 1) in the same line. The exterior winding of the balance-spring a is passed through the slot p of the spring (I. it follows, therefore, that by turning the crank k the slot 1) regulates the vibrations of the spring a without changing the position of the latter. By this arrangement considerable irregularities in the 1 running of a clock or time-piece, even up to thirty minutes, may be regulated. The camplate 9 is provided with two stops, at and 0, which prevent the crank it from being turned too far by the spindle i.
It is obvious that my regulating device for balance-springs can be used in clocks, watches, and other time-pieces by making such alterations which a person skilled in the art can readily execute.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a spindle, i, camplateg, mounted upon a sleeve of the spindle, a crank, h, pivoted to the cam-plate, a split pillar, (2, having a clamping-ring, f, and a balance-spring, a, secured to said pillar, e, substantially as set forth.
2. The combination of a cam-plate, g, a spindle, '17, having a crank, 7t, abent spring, (Z,
having slot, 1), and finger q, and a balancespring, a, passing through the slot p of the spring (I, substantially as set forth.
3. The combination of the spindle i, canr plate 9, the periphery of which corresponds to the exterior winding of the balance-spring, a crank, h, pivoted to said cam-plate and carrying a split pillar, e, and abalance-spring, a, attached to said pillar, substantially as set forth.
4. The combination of the cam-plate g, pivoted crank h, axially-turning split pillar 6, having conical ends, a clamping-ring, f, for compressing the conical ends of the pillar, and a balance-spring clamped by said split pillar, substantially as set forth.
This specification signed by me this 11th day of December, 1884.
ARTHUR JUNGHANS.
