WATCHMANS RECORDING-CLOCK.

Specification of Letters Patent.

Patented June 1, 1915.

Application filed March 24, 1913. Serial No. 756,602.

T0 all whom 'it may concern:

Be it known that I, FRANK P. FowLER, a citizen of the United States, residing at Phoenix, in the county of Maricopa and State of Arizona, have invented a new and useful latchmans Recording-Clock, of which the following is a specification.

This invention relates to a watchmans recording clock, and has for its object to provide a device which is of extremely simple construction and which may be located at any convenient point, for example, on the inside of the wall or window sash, with provision for the insertion of a key from the outside, whereby the watchman` in making his rounds can insert his key and operate the device, which will then indicate the time at which this was done.

In carrying out my invention, I employ a tape and with a suitable motor, constantly propel the tape. The tape is marked with divisions representing time which correspond to the speed with which it is moved by the motor, and when the watchman registers in the device, a mark is made in the tape at that time and thus a permanent record is made in the tape of the time at which the watchman appeared, which record may be inspected at any time. As a convenient motor for operating the tape, I employ a clock works.

Referring to the drawings: Figure 1 is a front elevation of the device with the cover swung open. Fig. 2 is a section on line :v2-m2, Fig. 1. Fig. 3 is a front view of the casing of a door, showing one position in which the hole for the insertion of the watchmans key may be arranged. Fig. 4 is a section on an enlarged scale, on line @c4-x4, Fig. 3. Fig. 5 is a plan view of the tape. Fig. 6 is a section on line m-m Fig. 1.

1 designates the case having a cover Q.

3 is the motor of any suitable construction which drives shaft 4, the latter serving to propel a tape 5 through any suitable medium, as for example, by means of the toothed wheel 6 against which the tape is pressed by a roller 7 carried by a pivoted arm 8 to which spring 9 is attached, which has suficient strength to produce the requisite pressure of the roller aga-inst the tape to cause the tape to be gripped by the toothed wheel. The tape is propelled in the direction of the arrow, Fig. 1, and as shown in Fig. 5, is provided with division marks 10 which are spaced apart distances corresponding to the movement made by the tape in one hour. IIalf hour division marks 11 and quarter hour division marks 12 are also employed. Numerals 13 are arranged at the respective division marks 10 to indicate the hour and these numerals are arranged in inverse order by reason of the tape traveling in a clockwise direction, Fig. 1.

After leaving the toothed wheel 6 the tape passes over a guide which may comprise a roller 14 as shown. The tape then falls into the case 1. In order to mark the tape, I provide a sliding rod 15 which is carried by a slide 16 mounted in ways 17, which ways are secured on the clock 3. The end of the rod 15 is sharpened and is adapted to puncture the tape when the slide 16 is advanced. The slide 16 is normally held retracted by a coil spring 18 and is actuated in the other direction by means of an eccentric 19 which engages pins 2O in the slide, the eccentric 19 being mounted on a shaft 21, the latter extending through the case 1 and through the building, as indicated in Fig. 4. The outer end of the shaft 21 is adapted to receive a key 22 which is inserted from the outside of the building by the watchman, and when engaged with shaft 21 and turned, will turn the shaft 21, operate eccentric 19 and thereby actuate slide 16 and cause the rod 15 to puncture the tape. If desired, the shaft 9.1 may extend through a protecting tube 23, with a suitable escutcheon 24 on the outside. The tape is sup* plied from a reel 25 mounted on the clock 3.

It is impossible for the watchman to turn the key too far in the wrong direction or injure the device, as the eccentric will actuate the slide if revolved in either direction. Moreover, the eccentric is capable of being revolved continuously so that there is no danger of breakage should the watchman turn his key more than one revolution.

It will be noted that the tape advancing means, the tape reel and the tape puncturing element of the device are all mounted upon the clock, and may be placed in the case and removed therefrom as a unit, thus simplifying the structure and making it easier to assemble the parts.

What I claim is:

1. A recording device comprising a case, a clock therein, a tape actuated by the clock, a slide, a punch carried by said slide and resting ad]acent said tape, a pair of pins punch-actuating means to effect said punching and disengaging operations of the punch When said key is turned a complete revolu 15 tion.

In testimony whereof, I have hereunto set my hand at Los Angeles,Ca1if0rnia this 17 th day of March, 1913.
