WATCI-IMANS TIME-RECORDING CLOCK.

Application filed August 8, 1925. Serial No. 48,927.

The present invention relates to time-1e cording clocks, and more particularly to those intended for registering the routine calls of patrolmen and watchmen in their rounds of duty and of a character best adapted for placement in locked and outof-the-way recesses, where they are fully protected and removed from all danger of being tampered with by those disposed to cover up remissness of duty, while, at the same time, being readily accessible to regularly constituted authorities for checking up purposes and dial changing, the patrolman or watchman registering his call through the medium of an inserted key, or the tripping of the mechanism through the agency of a pull-cord, either being readily accomplished from outside the wall, or partition, of the building in which clocks may be located.

The invention has for its principal object the provision of simple and efiicient manually controlled means for recording at regular and predetermined intervals the scheduled calls of patrolmen and watchmen at designated points in their rounds of duty.

A further object is the provision, in a device of this character, of a construction permitting installation in locked recesses, or between walls of buildings and adapted for actuation to record patrolmen and watchmen calls through the agency of pull-cords or a suitable key.

An additional object is the provision of a device of the character described that is of cheap and durable construction and of certain and positive operation.

Other objects and advantages will appear as this specification progresses, and be more clearly set forth in the claim hereto appended.

In the accompanying drawings forming a part of this specification, and in which similar characters of reference refer to like parts, throughout, I

Figure 1 is a plan section taken through the casing adjacent the dial, as indicated by the line 1-1 of Figure 2, the view being illustrative of the form of the casing and arrangement of the movable dial and perforated presser-foot positioned to back the dial while being perforated by the perforating needle;

Figure 2 is a fragmentary vertical section, showing the interior location of the ings, and in detail my invention comprises, i

in a preferred embodiment, a cylindrical casing 1 having a bottom closure 2 and a hinged topclosure 3 hinged to the cylindrical casing at 4 and provided with a lock 5 adapted to hold the hinged closure in locked relation with the casing.

The casing 1 is provided with a centrally arranged clock-mechanism 6 secured to the bottom closure 2 and provided with the ordinary hour-hand arbor 7 to which is attached frictionally a dial stem 8 bearing an annular flange 9 and threaded end 10 adapted to center and support a card-board dial 11. The dial is held in place upon the flange 9 by an annular clamping flange 12 having a knurled knob 13 and tapped to receive the stem-end 10 into which it is tightly screwed to compress the dial between the flanges.

The dial graduations 14 are arranged to read contraclockwise and run from 1 to 12, as indicated in Figure 1, so that, as the dial turns with the stem 7 in clock-wise movement, the dial graduations are consecu tively brought to position at a predetermined point in their travel, as indicated at 15.

The dial is scored concentrically, as indicated at 16, and the hour sub-divisions marked thereon, as shown at 17.

A perforating mechanism 18 is mounted in the casing and comprises a casting 19 having a flanged base 20 adapted to be secured to the bottom 2 of the casing by means of rivets, or the like, 21, the said casting being provided with a bore 22 extending from the bottom to near the upper end and a counter-bore 23 communicating therewith. The casting 19 is provided With a slot 24 formed adjacent its lower end and adapted to house a if-shaped member 25, said member being provided With arms 26 and 27 and a centrally disposed member 2 having a vertically disposed slot 29, the member being free for vertical movementrin the slot 2% of the casting and for rocking movement upon the pin 30 extending through the slot 29, as hereinafter described,

The member 25 is hole in its normal position, Figures 2 and S, by means of a follower-pin 31 fitted Within the bore 22 of the casting and having a tapered lower end 32 adapted to fit and bear in the crotch of the member the followenpin bearing a perforating member 33 which is provided with punch-point 34% extending through the counter-bore 23 of the casting.

it coil spring 35 is seated in the upper end of the bore 22 and bears against the upper end of the perforating member 33, the spring urge tending to normally seat the followerpin upon the memb r 25 and hold the punchpoint retracted immediately adjacentthe dial,- Figures 2 and 3.

A presser-foot 36 is integrally formed with the casing and positioned directiy in the path of the punch 34 and provided with a perforation 3'? positioned in the path of the punch and a larger opening 38 positioned adjacent said perforation to provide a sightopening through which the dial graduations may be viewed.

The punch 3d may be actuated by inserting a key 39 through the easing into the bore 22 until it abuts against the lower end 28 of the member 25, whereupon said member is raised upwardly to the position shown in Figure A} and the punch forced through the dial, the dial being held rigidly in place dur ing this operation by the pressenfoot 36', the parts being returned, upon release of the hey, to normal position, Figure 3.

The clock may be punched at hourly in;

tel-vale, or oftener if desired, and the exact time will be recorded upon the dial for future reference. The dial may be of disk formation and of paper or light card-board, upon which the graduations may be printed, thus affording a cheap and simple dial adapted for replacement every twelve hours, should it be required.

Should the clocks be placed in remote recesses or behind partitions, or other inaccessible iocations, cords or light Wire strands 40 and 4 1 may be attached to the extremities of the arms 26 and 27 for their actuation and lead to any desired place convenient for op eration, the rocking;' of the member 25 in either direction upon its point tending to cause the vertical movement of the followerpin and punch, by virtue of the cam like thrust imparted to the tapered end of the followerpin, the action serving to produce the necessary perforation.

Having thus described my invention, I claim, and desire to V secure by Letters Patent:

A device of the character described, comprising a perforating mechanism consisting of an upright cast member having a base and a bore extending from end to end thereof; a transverse slot communlcatmg with id bore and adapted to house a Y-shaped c in member, a slot in said cam member and a pin extending through said slot and proviuing a pivot-point and guide for said Y- shaped member, spring-pressed perforating member mounted in said bore and normahy resting: in the crotch of said Y-sha-p'ed member, and means for manually rocking said Y-shaped member to force said perforating member outwardly against the spring urge.

In testin'iony whereof I have hereto affixed my signature.

PETER W KANE.
