RECORDER.

Speciication of Letters Patent.

Patented Feb. 25, 1919.

To all whom t may concern:

Be it known that I, GEORGE S. BROWN, citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented new and useful Improvements in Recorders, of which the following is a specification.

This invention relates to workmens recorders in which the time record is made by a set of printing wheels on individual cards inserted into the machine, the object of the invention being to record the time consumed on jobs by arbitrary periods, such as six minutes each, so that ten periods are contained in one hour, and to permit the use of an ordinary clock mechanism for actuating the period counting mechanism.

The invention also has for its object to provide a machine of the kind stated which is comparatively simple and inexpensive in construction, and in which the number of parts is reduced to a minimum.

The objects stated are attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawings forming a part of this specification.

In the drawings,

Figure 1 is a side elevation of the mechanism, partly in section;

Fig. 2 is an elevation of a certain portion of the mechanism; y

Fig. 3 is a front elevation of another portion of the mechanism, and

Fig. 4 is a vertical section on the line 4-4 of Fig. 3.

Referring specifically to the drawings, 10

denotes a set of three recording and printing wheels having printing characters on their peripheries arranged to record periods consisting of one-tenth hours, starting from `zero and continuing until the limit which the mechanism is adapted to record has been reached. One of the wheels is a -units wheel, the next is a tens wheel, and the next is a hundreds wheel, the combined total which the wheels are adapted to register, without resetting, therefrom being 999. A suitable transfer mechanism is provided whereby a wheel of higher order is 'advanced one step each time a wheel of the next lower order has made one complete revolution, and as such mechanism is well known in the art, it has not been illustrated.

The units wheel is rotated one step every six minutes during the working hours of the shop or other establishment. This actuating mechanism will be presently described.

Alongside the wheels 10 are two ` more printing wheels 11 and 12 respectively, one of which prints the date and the other the month. The date printing wheel 11 is actuating by a mechanism to be hereinafter described, and the month wheel 12 is adapted to be set by hand.

At 13 is shown an ordinary clock which is employed for controlling and operating the printing wheels 10, 1l vand 12. A shaft 14 is geared to one of the gears of the clock train. Through gears 15, the shaft 14 drives a shaft 16 supporting the printing wheels 10, 11 and 12, these wheels being movable independently of the latter shaft and not turning therewith. On the shaft 16 is made fast a snail cam 17 which actuates a lever 18 carryinga push pawl 19 engageable with a gear 20 on the wheel 11 for rotating the same step-by-step. A detent 21 is also provided for lockin the gear 20. The parts are so constructe and arranged that the push pawl first disengages the detent, and then rotates the gear 2O one step, after which the detent returns to holding position; This is a well-known form of actuating mechanism and a further description thereof is not deemed necessary. It will be understood that the gearing between the shaft 16 and the clock train is so designed that said shaft makes one revolution every twenty four hours, and hence the push pawl advances the wheel 11 one step every twenty four hours. l

The clock 13 is also employed for dividing the working hours into six-minute periods, and for controlling the period printing wheels 10, the following mechanism being provided for this purpose.

At 22 is shown a disk having its face divided into twenty-four numbered spaces, and in front of this disk, coaxially therewith, is a ten-point cam wheel 23. The disk is designed to make one revolution every twenty four hours, and the cam one complete revolution every hour, they being driven by the clock train through a suitable gearing. As shown, the cam is fast on a shaft 24 having a pinion 25 meshing with a gear 26 on a. shaft 27 which is geared to the shaft 14 as shown at 28. The disk 22 has a. hub 29 through which the shaft 2a loosely passes, and on said hub is a gear 30 meshingll-With a pinion 31 on the shaft 27.

Extending across the face of the disk 22 and the cam 23, is a reciprocatory bar vr32 having a slot 33 to clear the shaft 24. The lower en d of this bar has a spring pawl tooth 34 and on one side of the units Wheel 10 are ratchet teeth 35 engageable by the paWl tooth. Through this pawland-ratchet mechanism, the units Wheel is advanced one step every time the bar 3,2 drops. The bar 32 carries a roller 36a positioned to ride on the multiple cam surface of the cam `23, and When said rollerclears the highestkpoint ofv each cam, the bar drops and lactuates the units Wheel. Inasmuch as the cam has ten points and it makes one revolution every hour, the units Wheel is rotated one step every six lminutes.

The periphery of the disk22 has a lateral flange v36 onpWhich isy ,adapted to ride a lateral flange37 on the upper end of the b ar 32. The flange 36 does not extend entirely around thedisk, leaving a certain portion thereof unobstructed. When the flange `37 is riding the flange 36tthe bar 32. is held elevated and prevented from droppingto actuate the units Wheel 10. The flange 36 Will bey positioned on the disk 22 to correspend to the time the shop or establishment is closed, .and a small ila-nge 38 is provided for the noon lunch period. It Will therefore beseen that the vperiods are counted and registered only during the Working hours.

Associated With the lprinting WheelslO, ll and 12 is an inking ribbon 39, and other suitable adj uncts so that the periods may be imprinted on the workmans check or card. In practice, the Worlnnan, is given a card With each job, and When he starts the job he inserts the cardinto the machine to imprint thereon the month, the date and the particular period. When Vthe job is-'iinished the date and period are again imprinted on the card, Yso that the ylatter ,now shows the exact number of periods consumed on the job.

printing Wheel, and controlled by the cam, Hand means on the rotatable memberfor holding the bar inoperative during certain periods of the revolution of said member.

2. In a recorder, a period printing Wheel, a time-train actuated rotatable member, a time-train actuated multiple pointed rotatable cam coaxial with said member, a. reciprocatory b ar having means for advancing the printing Wheel, and controlled bythe cam, and means on the rotatable memberfor holding the bar inoperative With respect tothe cam during certain periods of the revolution of said member.

3. In a. recorder, a period printing Wheel, a time-train actuated rotatable member, a, time-train actuated multiple` pointed rotatable cam coaxial with said member, a reciprocatory bar having means for advancing the printing' Wheel, and controlled by the cam, the bar having a portion overhanging and engaging the periphery of the rotatable member to hold the bar inoperative, and said eriphery having its surface interrupted to orm a gap for releasing the bar when its overhanging portion reaches the same.

4l. In a recorder, a time-train actuated rotatable shaft, a multiple pointed can] fixed on said shaft, a time-train actuated rotatable member loosely mounted on said shaft, a period printing Wheel, a reciprocatory bar having means for actuating the printing Wheel, said bar extending diametrically vacross the aforesaid cam and member, and having a laterally projecting part riding on the cam, and means on the rotatable member for holdingthe bar clear of the cam during certain periods of the revolution of lsaid member.

In testimony whereof` I aliix my signature.
