ROBERT C. SALOCI-I, OF ST. LOUIS, MISSOURI.

CLOCK.

To all whom it may concern:

Be it known that 1, ROBERT C. SALooH, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Clocks, of which the following is a specication, containing a full, clear, and eXact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates generally to improvements in clocks, my object being to construct a novelty clock for show and display purposes.

To the above purposes, my invention consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully set forth, pointed out in the claims, and illustrated in the acpanying drawings, in which:

Figure 1 is a front elevation of my improved clock; Fig. 2 is ya side view; Fig. 3 is a section taken on the line 3-3 of Fig. 1; Fig. f1 is a section taken on the line 1 -1 of Fig. 1; Fig. 5 is an enlarged rear view of the minute hand with the casing of the works removed and also the casing of the counterweight; Fig. 6 is a rear view of the dial with parts broken away; and Fig. 7 is a section taken on the line 7--7 of Fig. 6.

Referring by numerals to the accompanying drawings: 1 indicates a portable stand which is provided with parallel upright arms 2, and in the top portion of said arms are formed V-shaped recesses or bearings 3.

et indicates the dial, which is constructed of concentric wires 5 and 6, suitably spaced apart, said wires being secured to radial wires 7 and the inner ends of the radial wires 7 being properly secured to a hub 8. Said hub 8 is provided with a central opening 9, in which is located a shaft 10 for support-ing the dial and the hands of the clock. As 1 have shown the dial, it is loosely mounted on said shaft, but if it is desired it may be rigidly secured thereto. Vhen the clock is assembled, the shaft 10 is located in the recesses 3 of the arms 2. Mounted on said shaft is a screw-threaded nut or thumb-piece 11. On the opposite end is a friction thumbpiece 12, which answers the purpose of holding the shaft in the bearings in the proper position. Mounted on the concentric rings 5 and G are the usual dial numbers, running from 1 to 19.. These numbers may be secured to these rings by being soldered or bybeing riveted, or in any suitable manner.

13 indicates the minute hand, which is provided with a hub 14, said hub 14k being provided with a suitable opening through which the shaft 10 passes, and thus said minute hand is loosely mounted on said shaft.

15 indicates the hour hand, which is provided with a hub 16, provided with a suit-- able opening through which the shaft 10 passes, and said hour hand is also loosely mounted on said shaft 10.

Mounted on one end of the minute hand 13 is an ordinary watch movement 17, and attached to the center arbor 18 of said movement is the arm 19, and attached to said arm is a weight 20. Said arm 19 and weight Q0 are rotated and moved by means of said watch movement. Mounted on the opposite end of said minute hand is a counter-weight 21, which is first adjusted to balance the weight of the watch movement located on the other end of said hand, and also the arm and weight 19 and 20, and when so first adjusted said hand will then assume a horizontal position across the face of the dial. The running of the watch movement will impart a rotary motion to the arm 19 and weight 20, and as the continuous movement of t-he arm 19 and weight 2O will change the center of gravity of said minute hand 13, it will cause it to turn or revolve on its own axis, and as the arm 19 and weight 20 make one revolution in one hour, it will compel the minute hand 13 to do the same and make one revolution in one hour. Mounted on one end of the hour hand 15 is a similar watch movement, and secured to the hour wheel of said watch movement is a similar arm 19, carrying a similar weight 20, and mounted on the opposite end of said hour hand 15 is a counter-weight 22. The operation of the hour hand is the same as that of the minute hand heretofore described, only that it makes one revolution in twelve hours. 1t will thus be seen that said hour and minute hands are loosely mounted on the shaft, each one being provided with a watch movement and a counter-weight, and fixed to the center arbor of the minute hand movement and to the hour wheel of the hour hand movement is an arm 19 carrying a weight 20, which are moved by the ruiming of the movements, and such a movement of said arms 19 and 2O carried by the respective movements will cause the hands to move independently and keep time.

Referring to Figs. 6 and 7, it will be seen that I have provided the numeral (3 on the dial 'with a lead Weight Q3, Whieh causes the rotary dial to keep in the proper position; that is to say, with the numeral l2 at the top, and it said dial iS rotated, it will gradually assume said position.

F rom the lioregoing, it will be seen that l have provided what might be called a novelty and display eloek, which is adapted to keep accurate time.

l elaiin:

l. A eloek, eo11'1prisingl a stand, parallel stamlards secured to said stand, a sha'litl mounted in said standards, a skeleton dial mounted on said sha'lt, an hour and 111i11ute hand loosely mounted on said shaft, eaeh oit which carries a u'ateh movement and a counter weight, a weight seem-ed to the eenter arbor olt the minute hand movement, and a similar weight secured to the hour wheel ot the hour hand 1no\e111e11t.

ln a eloek of the class described, a shaft, a skeleton dial loosely mounted on said shalit ',arrying the usual numbers ilirom .l to l2, a minute hand and an hour hand loosely mounted on said shalt in front et .'aid dial, a wateh movement carried by one end ot' each of said hands, a counter weight carried by each of the opposite ends of said hands, a weight secured to the Center arbor of the movement carried by the minute hand, and a similar Weight carried by the hour wheel of the movementearried by the hour hand.

2l. A eloek of the elass deseribed, Comprising a shalit, a skeleton dial carrying the usual numbers trom l to l2 loosely mounted on said sha'tt, a weight secured to the periphery ot said dial diametrieally opposite the numeral l2, a minute hand and au hour hand loosely mounted on said shat't in trout ot said dial, a similar watch movement earried by one end ot each ot said hands, a similar eounter-weio'l1tcarried by eaeh ot they opposite ends ot said hands, a weight 1u the iliorm ot a .segment ot a elrele seeuled to the center arbor oli the movement eal'l'ied by the minute hand, and a similar weight earried by the hour wheel oli the movement earried by the hour hand.

ln testimony whereof, l have signed my name to this speeilieation, in presenee oli two subseribin;I witnesses.
