ALBERT P. HODGE, 'OF WINSTED, CONNECTICUT, A SSIGNOR TO WILLIAM L. GILBERT CLOCK COMPANY, OF WINSTED, CONNECTICUT, A CORPORATION OF CONNECTICUT.

CLOCK.

Application filed July 30, 1921.

To all whom it may concern.

Be it known that I, ALBERT P. Home, a citizen of the United States, residing at Winsted, county of Litchfield, State of Connecticut, have invented a certain new and useful Improvement in Clocks, of which the following is a. full, clear, and exact description.

My invention relates to improvements in clocks and has for its object to provide a new and improved means for setting the hands of a clock having a rearwardly extending winding-key or keys. It further has for its object to provide hand setting means which shall be concentric with the key-arbor.

The following is a description of an improvement of my invention, reference being had to the accompanying drawings in which,

Fig. 1 shows a rear view of a clock embodying my invention;

Fig. 2 shows the same with the winding keys and back plate removed;

Fig. 3 shows on an enlarged scale a partial section on the line 3, 3, Fig. 1;

Fig. 4 shows a detail of one of the gears used in embodying my invention and its securing means;

Fig. 5 shows on an enlarged scale a section on the line 5, 5, Fig. 1; and,

F Fig. 6 shows a section on the line 6, 6,

Referring more particularly to the drawings, 1 is a back-plate of a clock case 2. 3 is a clock mechanism having a main-spring arbor 4, a main-hand-setting arbor 5, an

alarm-spring-arbor 6 and an alarm-hand-' setting-arbor 7.

The arbors 4 and 6 are provided with keys 8 and 9 secured thereon in the ordinary manner. Ordinarily, the arbors 5 and7 are provided with knurled extensions. These ordinary knurled extensions are so close to the keys 8 and 9 that they are diflicult to manipulate particularly when the keys are so positioned that their planes pass through axes of the hand-setting-arbors. In order to avoid this difiiculty, I provide the arbors 5 and 7 with gears 10 and 11 and mount upon the arbors 4 and 6 gears 12 and 13 meshing therewith. These gears 12 and 13 have secured thereto knurled sleeves 14 and 15 ex- Serial No. 488,502.

tending outwardly through the back plate 1 and surrounding the spindles of the keys 8 and 9, respectively. The inner ends of the sleeves are contracted so as to be engaged by the ends of the keys. The gears 10 and 11 are preferably detachably secured to their arbors, and to this end I provide them with slots 16 fitting over pins '17, as shown in Figs. 4 and 6. This pin and slot connection holds the gears from rotary movement relatively to their respective arbors. They are held against relative axial movement by the back-plate 1 which is in juxtaposition to the gears 10 and 11.

Upon removal of the keys 8 and 9, the back-plate 1 can be removed and thereupon the gears 10, 11, and 12, 13 can be lifted off, the operation of assembling being the reverse.

With this construction the four winding and hand setting devices are grouped about two axes and the hand setting devices are equally accessible whatever may be the positions of the winding keys. The construction requires simply the addition of the gears 10. 11, 12, and 13, together ,with a pin 17 through the shaft 5 and the cutting off of the1 ursually projecting ends of the shafts 5 an The keys 8 and 9 and their arbors are so threaded that the keys stop before they clamp tightly upon the gears 12 and 13 but act to definitely position those gears in the absence of the back-plate 1.

As will be evident to those skilled in the art my invention permits of various modifications without departing from the spirit thereof or the scope of the appended claims.

hat I claim is:

1. In a clock, a spring-arbor, a handle connected thereto and constituting winding means and hand-setting means revolubly mounted on said arbor and comprsing a sleeve projecting rearwardly toward the outer end of said handle and surrounding the body portion thereof, the inner end of the bore of said sleeve being contracted so as to form a flange and the end of said body portion abutting said flange.

2. In a clock the combination of a spring arbor, a hand setting arbor, means for rotating said hand setting arbor comprising a gear secured on the rear end thereof, a second gear engaging the first gear loosely mounted on the rear end portion of saidspring arbor and having a rearwardly extending operatlng handle arranged eo-axially therewith and an operating handle screw- ALBERT P.
