Beit known that I, 'lnnononn limesciinunnn, a subject of the :Presifiient e Switzerland, residing at Detroit, in :he county of "Wayne and Staten l c have inventelil certain new and us proveinents in Timing Systems; and tlecla're the following to be :1 full, clear, and exact description of the invention, such as Will enable elihcl's skilled in the llil' in which it zipperhiins to n like and use the S%U1'1P;i'-" i ence being had to the accompanying? (leer ings, and lo the letters and figures o. ence marked thereon, which form :1 plus of i'his specification.

This invention relates in new and improvements in means for i'imii l springs on balance Wheels of u. clocks. The nianufaei'ui'eis oi i i-niche clocks usually perform this Worli; or have it perihn'lnecl by highly shil eal after who 11 :iii' springs and balance wheel. we placed in the lnevcnienls.

block 15, where the hair spring is crimped or marked as at 35, and is cut oft. The crimp indicates the point where the end of the hair spring vis pinned to the support which maintains. it in operative position in the clock or watch movement. The die 27 works in. connection with the die 28 on a plunger rod 29 whichis mounted in apertured lugs 30 projecting from lever G, and said plunger rod is controlled by a spring 31. The die 28 is operated by finger-pieces 32 to crimp and sever the hair spring and to prepare the same for attachment as shown in Fig. 4. I

In Figs. 1, 2 and 3, I have shown the vibrator or instrument designed to adjust to time a hair spring of the form shown in Fig. 4 with the crimp outward, but it will be understood that the instrument may be designed to adjust a hair spring with the convolutions running in the opposite direction and withthe crimp lying inwardly as shown in Fig. 5. V Q

Referring to Fig. 1 ,.in placing a hair spring and balance wheel in a position to he timed, the short end of the s'hafti-W of the balance wheel 38 is placed in the counter sunk end of a supporting screw 39 which penetates the base and is adplstable. The upper end of the'stat'f 37 extends into the spring 34 but is loose. The upper end of the spring 1s inserted between the two rollers 37 and 21. The vibrator is then permitted to operate. The vibrations of the lever impart reciprocating movement to the spring and balance wheel, and these reciproeating movements, it not roperly responsive to the movements of t e lever, the two elements may be brought in synchronism by tions of said hair spring will be in unison with the vibrator and the master clock, and means for marking the hair spring at the point where it is to be pinned to the movement.

2. A vibrator for timing the hair springs of clocks and watches, comprising a lever, electrical means for vibrating said lever in unison with a master clock, means for supporting a hair spring and balance wheel below the lever, means supported on the lever for holding and determining the lengths of the. springs, and means for marking or timing said springs to indicate the point of pinning said springs to the. clock or watch movements.

3. In a device for timing the hair springs of clocks and watches, the combination of an electric circuit, a master clock and an electro-n'iagnet in said circuit, a lever vibrated by said magnet, a chuck supported on said lever havinga slot for the insertion of the outer end of the spring, rollers carried in said chuck and engaging the end of the spring projected through said slot, and a die carried on said lever for marking the spring at the point where it is to be pinned in the movement.

4. In a device for timing hair springs of clocks and watches before they are placed in the movements, the combination with an electric circuit, a master clock and an electro-magnct in said circuit, a lever vibrated
