WATCHMANS RECORDING-CLOCK.

Specification of Letters Patent.

Patented June y26, 1917.

Application led September 20; 1915. Serial No. 51,545.

T0 cZZ whom t may concern:

Bc it known that I. Isaac A. Hannan-WN; a citizen of the United States. residing at Elyria. in the county of Lorain and State of Ohio, have invented a certainnew and useful Improvement in lllatchmens Recording-Clocks7 of which the following` is a full, clear; and exact description, reference being had to the accompanying drawings.

This invention relates to recording clocks and particularly to the kind of clocks used bv nightwatchmen and patrolmen to enable them to record with certainty and accuracy the fact of 'their being at their post of duty at a given time but to prevent either them or anyv one else from going over the record at any time and filling in blanks, or from opening the device and obtaining access to any part thereof without leaving a record of the same. subsidiary object of the invention is the provision of means for preventing the making of a record excepting during that portion of the day during which the watchman is on duty and from preventing any days record from becoming exposed until that day has arrived. Other objects of the invention relate to the construction whereby a simple; economical and reliable device is produced. while additional objects and advantages will become apparent as the description proceeds.

Generally speaking my invention may be defined as consistingl of the combinations and constructions recited in the claims annexed hereto and illustrated in one embodiment in the drawings accompanying and forming a part of this application, wherein Figure 1 is a front elevational view of the complete device in operating condition, the full lines showing the shield swung aside to permit the making of a record and the dotted lines showing the shield closed and locked in place; Fig. Q is a view drawn to enlarged scale showing my improved recording clock with the cover thrown wide open to disclose the interior construction; Fig. 3 is a cross sectional view taken immediately inside the closed cover of the casing, a portion of the rotatable shield being broken away; Fig. 4 is a view of the device with the record sheet removed and the cover swung half open so as to disclose its edge view; Fig. is a detail view taken upon the line 5-5 of Fig. 3 showing the lock in securing position; Fig. G is a detail view of the lock viewed from the opposite direction from that shown in Fig. 5, the lock being' shown in released position; Fig. 7 is a view similar to Fig. G showing the lock in intermediate position; Fig'. 8 is a detail view showing the method of securing the record sheet in place and for adjusting the shield moving member; and Fig. 9 is a perspective view of one form of recording tool.

Describing the parts by reference characters. 1 indicates a metal casing preferably of cylindrical shape and adapted to be secured against a` wall or other convenient location in any suitable way as by interior screws 3 indicates aY circular cover hinged to said casing in any suitable manner as by the lugs -t-t and preferably having an overhanging rim 5 closely surrounding the casing. Carried by the interior of the cover at a point removed from the hinge is a locking post G having therein an aperture T, said post being arranged to enter the aperture S of a suitable lock and there to be engaged by the locking bolt 9.

Inside the casing I locate a suitable chronometer movement indicated generally at 12 (Figs. sland 5) having coaxial with the casing 1 a rotating spindle 13 terminating in a flat table 1l. Secured to this table in any suitable manner so as to rotate therewith is the record sheet 15. which is preferably of printed paper having the days of the week marked thereon in concentric circles and the hours from 1 to 12 marked thereon in radiating lines as shown in Fig. 2. One convenient mode of securing this sheet in place is to provide the table 1l with a central boss 16 having pivotedthereto a cam lever 17 and to insert beneath said cam lever a slotted plate 1S afterward turning the cam lever down thereon to the position shown in Fig. Q. `Between the plate 1S and the surface of the paper I insert a flat washer 19 formed with a radial finger 2O whose purpose will be hereafter described.

Secured to the interior wall of the casing 1 and projecting radially inwardly immediately in the rear of the paper sheet is an anvil having its forward face preferably provided with spaced depressions 26, and formed in the cover opposite these depressions is a row of apertures 27, one :tor each depression. The record is formed by inserting into one of the apertures 2T a key of the type shown in Fig. 9 so as to prick or dent the paper into the corresponding depression '26, the time of thisv prick being recorded by the rotation of the disk, and the particular aperture open at the time being governed by the means now to be described.

Journaled to the inner face ofv the cover is a flat circular metal disk 30 having therein a plurality of apertures 31a, 31h, 31C, Slfl, 31e, 3P, 8lrx=r arranged so that as said disk is rotated said apertures come one by one into alineinent with the various apertures 27. Preferably one portion of the periphery of the disk is formed with V shaped notches 32 adapted to be engaged by the J shaped spring 33 whereby the disk is held impositively in any position to which it is set. Another portion of the periphery of said disk is formed with ratchet teeth 34 adapted to be engaged by a pawl 35 carried at the end of the swinging lever 36 pivoted at 3T to an arm 38 also carried by the cover and projecting across the inner face of said disk. Upon the opposite side of the pivot 37 from the pawl 35 said arm is formed with a horizontally projecting linger 39 adapted to be engaged by the nger 29 upon the rotation of the spindle, thus displacing the arm 36 and advancing` the disk one step. A counterweight 40 may be employed for returning the arm to original position.

ln order to prevent the opening of the casing without leaving a record thereon l provide means whereby the turning of the lock shall punch the paper, and the simplest eX- pedient for this purpose which l have so far devised is that shown in Figs. 3, 5, 6 and 7. According to this 'construction the lock consists of a plate having journaled therein a rotatable stud 46 furnished with a radial arm 47, the end of which is bent circuini'erentially to form the locking bolt 9. Carried by the plate 45 is a slotted support 48 between the halves of which the record sheet passes as shown in Figs. 5, 6 and 7. Said support is also formed with a second slot 50 perpendicular to the paper, and pivoted upon the face of the plate 45 at one side ot the stud 4G is a striker 51 having its free end turned as shown at and provided with a cutting edge adapted to be inserted into the slot 50 and to punch the paper at that point. Normally said edge is held in retracted position by suitable means such as a spring 53, while its forward movement can conveniently be produced by means of a ra` dial iinger 54 on the stud 46 engaging a flexible feather on the striker 51, whereby said striker will be rocked to the position shown in Fig. l after which the 'feather slips oli1 the linger and the striker is retracted allowing the free removal of therecord sheet. Upon turning the stud into locking position the finger 54 engages the feather 55 in reverse direction as will be obvious from an inspection ot Fig. 6 whereupon the feather merely yields without displacing the striker.

The lower end of the anvil 25 is provided with an indication of some nature such as hat shown at 58 to aid the setting of the dial. The inner face of the disk 30 is preferably covered by a bridge 59 spaced from the inside of the cover so as to permit the free rotation of the disk but serving to prevent deformation of the same as by catching of the key therein. Apertures 59 are formed in the bridge 59 in alinement with the apertures 27 in the cover. At one side of the bridge 59 the disk 30 is provided Tith a stop pin G0 adapted to engage the side thereot1 at a point one step beyond the rst aperture 31a; on the other side of said bridge the disk 30 is provided with a stop pin 6l adapted to engage said bridge when said disk'has been turned one step beyond the aperture 31g. rlhe exterior of the cover is preferably provided with a pivoted shield 62 which may be either swung aside to permit the insertion of the recording key or secured in place by the padlock 63.

lilith the construction herein described eX- perience has shown that if the linger 20 be located in alinement with the eleven oclock division of the dial, the disk 30 will be shifted one step each time that the six oclcck division-passes the point 58. This relation is utilized in setting the device in the following manner z-Supposing that a new record sheet is to be applied on Sunday afternoon at three oclock; the record sheet is placed with its three oclock division in register with the pointer 5S, and the washer 19 is located with its finger 2O in alinement with the eleven oclock division of the sheet. The disk 30 is turned until the pin GO engages the bridge 59, thereby leaving all of" the apertures 27 closed, after which the cover is shutand locked. At six p. m. on ASunday the movement of the finger 2O shifts: the disk 30 one step as heretofore explained, so that until 6 oclc-ck Monday morning the watchman can insert his key through the aperture 3l without obstruction, thus making a record all the way around the disk in ease his visits are rightly timed. t six oclock Monday morning the movement of the finger 20 advances said disk another step so tha all the openings are closed, which condition is retained until six p. m. Monday whereupon the movement of the disk opens the aperture 31h, permitting the second concentric record to be made while shielding the first record against mutilation or falsification. This continues until the end of the week when the sheet will be entirely finished.

f the Watchman or any other interested person should attempt to vvork the disk around by prodding it through the aperture 2T With a key or other Jcool, the most t iat they could do would beto advance the disk, theeby throvving the registration a day ahead and indicating clearly that the clock had been tampered With, but Without the possibility of mutilating the record already made. ln case the lock vvere manipulated to open the casing the record sheet Would be punchedL in the manner heretofore described, and the angular relation of the punch and point 5S will invariably afford a clue as to the time of opening.

l am avvare that important features of my improved clock can be employed vvithout employing all of the saine; also that many changes in point of arrangement and design can be made vvithout departing from the scope of my inventive idea or losing the benefits of in v invention. The expression reco 1d receiving means or record receiving element used in the claims is intended to cover anyr substance or surface capable of receiving a mark, cut, prick or stamp, vvhether of aap-er, cloth, metal, Wax or other substance, and Whether round, square` flat, convex, concave or Warped; the expression impressing is intended to cover the production of any intelligible mark, Whether by cutting, pricking, marking, stamping, with a tool, pencil or pin, by chemical or electrical means; the expression series of apertures is intended to cover either a series of spaced apertures or a series of apertures merging together so as to produce in effect an elongated slot; accordingly, l do not propose to limit myself to such details except as the same may be positively included in the claims hereto annexed or may be rendered necessary by the prior state of the art.
