TIME RECORDER.

Y Patented Apr. 18 1922.

Application filed November 27, 1920. Serial No. 426,714 I To allwhom it may concern:

Be it known that I, JAMES W. BRYCE, a

,citizen of the United States of America,

lowing is a full, clear, and exact 'descrip tion.

In the use of workmens time recorders and like devices, it 1s customary to install a master clock at some central point, and a lurality of secondary clocks at such points in the establishment as they may be needed and by means of such secondary clocks, synchronized with the master clock, operate the time indicating mechanism of recorders. The workmen, coming, going, or starting and stopping work, insert-their cards in a recorder and by manually operating a handle print the time at appropriate points thereon. I i I Considerations of eiiiciency and practicability require that the secondary clocks be capable, of continuous operation, and for this reason they are habitually equipped with winding motors which at definite intervals are energized and caused to wind up the propelling weights or springs and heretofore the function of the motor has been I have sought to solve, but the main .difliculty has, been to accomplish it without adding'to the complication of the apparatus,

or increasing thenumber and expense of its essential parts, and this difiicultyl have succeeded in large, measure in overcoming by the 31am for which I now seek protection by tters Patent. I

According to my present. invention I utilize the same motor both for winding the secondary clock and for operating the time motor, which is therebyv caused to work the printing mechanism. To do this in a way whlch Wlll not interfere with its normal functlon of winding requires the use of special devices which are hereinafter described. The drawings annexed illustrate v the means employed for the purpose;

Fig. 8 is a wiring diagram showing the circuit connections of the clock and recorder which are directly involved in this improve- I ment.

The clock as well as the recorder is or may be of any well known construction, and no further descriptionof either, for purposes of this case, is required than to state that the clock, by means of a rod 1, operates the time indicating disks of the recorder, that at given times a workman inserts .his card in the chute ,2, and either by operatingthe handle 3, Fig. 7, manuall or I by pressing a button hereinafter described, operates the printing hammer or pad 4 to print the indicated tune at the proper point onhiscard. 7 v

The. clock contains a motor 5, which by meansJof an 'automatiocircuit controller 6, is thrown into, operation periodically to wind the clock. Any means may be employed for this purpose, but in thepresent case I have shown a lever 7, which when shifted forces to the right fig l nk 8 (see Fig.

8) which brings together two contacts 9, 10, and thereby closes the motor circuit to wind the clock by the rotation of a shaft 11. This is a standard form 01'' winding mechanism in general use, and is described in detail in a patent granted to me on Feln'uary s, 1921, No. 1,367,534..

This shaft carries loosely mounted thereon a sleeve 12. having a worm 13 and said sleeve has a toothed end, with which a similarly toothed sleeve 14. keyed to but slidable on the shaft, is adapted to be thrown into engagement by the armature lever 15 of an electromagnet 16, when said magnet is energized. This magnet, as shown in Fig. 8, is in circuit with the motor 5, and when the motor circuit is closed through and by the contacts 9 and 10, the magnet is also energized and connects the worm with the motor driven shaft 11 and thereby winds up the clock by means of a spur gear 66. It will be observed that the motor winds the clock only when the circuit of magnet 16 is closed.

The motor shaft carries at its end a bevel gear 17, which meshes with a similar gear 18 on a vertical revoluble rod 19, which by means of a gear 20 drives a short sleeve 22, 011 the drive shaft 21 01. the recorder. This sleeve has a toothed end and on the drive shaft 21 is a sleeve 23 with a similar toothed end which is normally impelled toward the sleeve 22 by a spiral spring; 24. The sleeve is keyed to the shaft 21, but capable oil slidin thereon.

Tivoted at 25 a lever 26, normally drawn down by a spiral spring 27, andv this lever when depressed operates as a stop to prevent the sleeve 23 from engaging with the sleeve 22. The lever, however, constitutes the armature of an electromagnet 2S and when this magnet is energized it is raised to release the sleeve 23, and to thereby produce the rotation of the shaft 21.

On this shaft is a cam 29 upon which travels a stop 80, and when the shaft begins to turn the armature lever 26 is held up out of engagement with the sleeve 2 so that the circuit of magnet 28 may then be broken without stopping the rotation of shaft 21, which does not stop turning until the stop 30 drops off the cam and permits the lever 26 to force back the sleeve 23 out of engagement with sleeve 22.

On the frame of the recorder is mounted a vertically movable plunger rod 31, with a push button 32 at its top end. On this rod are two pins 33, 34, and when the rod is pushed down the pin 33 forces to one side apivoted lever 35 which depresses the righthand or free end of a contact lever 37. By the same movement the pin 34: depresses the left-hand arm of a lever 38, which thereby comes into engagement with contact lever 37, and by this means the motorcircuit is connected through wires 4.0., 41 and +12 to the electromagnet 28. The shaft 21 is now set in rotation.

On the shaft 21 is a pair 01 cams 13 and 51 with their contacts wired in multiple. The purpose of these cams is to insure accurate timing of the making and breaking of the motor circuit and to maintain the current on the motor through a complete cycle of the recorder. In this case one revolution of the shaft 21.

Immediately upon the starting of the sha it 21 the contacts on cam 1-3 'l'all oil. the rise ot the cam and come together. As the revolution continues the contacts on cam 51 are brought together. A little later, as the movement continues, the contacts on cam are separated and the circuit is maintained closed by the contacts on cam 51 until at the close of the cycle they drop oil the rise of the cam 51 and the motor comes to rest, with clutch 23 disengaged.

Soon after shaft 21 starts rotating cam -17 moves catch 18 out of engagement with contact lever 37, permitting contact levers 3T, 88 to separate. This would open the motor circuit were it not. for the contacts on the cams 4:3 and 51.

The purpose 01"- the construction of the starting button 32 etc. is to make it impossible to have the shaft 21 rotate more than once for one pressure of the starting button 32. With the construction shown, continued pressure on button 32 will cause the mechanism to function only once.

On the shaft 21. is a cam 49 that engages a roller on the printing lever 50, and by each revolution of the shaft 21 this lever is caused to throw the printing hammer 4e, and print the card which is in the recorder. As pre- -iously explained, this lever may be worked by hand, it so desired.

It will be observed'that at any time without reference to the conditions existing in the device, that is to say, whet-her the clock is being wound or not, the depression of the key 32 will result in the operation of the 'n'inting mechanism but that such operation has no effect upon any other part of the clock mechanism.

From the above it will be seen that the winding and the printing operations as performed by the motor are independent of each other, and that the motor may he used for operating the recorder during the periods in which it is winding the clock without in any way interfering with its operation. By means of this apparatus the duty imposed upon a workman in printing his time, is limited to the simple operation of inserting the card and pushing a button, and this is a great practical advantage.

W hat I claim as my invention is- 1. The combination with a time recorder and a clock for controlling thetime mechanism of the said recorder, of a motor, means for periodically connecting said motor to the Winding mechanism of the'clock, and independently operated means for connecting said motor to the printing mechanism of the recorder.

2.

4. The combination with a time recorder and a clock for operating'the time mechanism thereof, of a vmotor and a shaft driven thereby in the clock and a shaft for operating the printing mechanism in the recorder, electrically controlled means in the clock for connecting the motor shaft with the winding mechanism, means in the recorder for connecting the printing shaft with the motor shaft, and means for interrupting such latter connection after one revolution of the "printing shaft.

5. The combination with a time recorder and a clock for operating the time mechanism thereof, of a motor and a shaft driven thereby in the olock,-a shaft for operating the printing mechanism in the recorder, clutches between said motor driven shaft and the winding mechanism of the clock, and the printing shaft of the recorder, and independently operating means for operating said clutches whereby eitherthe winding mechanism or the printing shaft may be connected with the motor driven shaft.
