TIME-RECORDING LOCK.

Specification of Letters Patent.

Patented Sept. 29, 1914'.

Application filed February 24, 1914. Serial No. 820,646.

To all whom it may concern:

Be it known that I, Eowm S. PHELPS,

a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Time-Recording Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. My invention relates to registering time locks of the type which makes a record of the time, or hour and fraction of an hour, when the lock is,operate d to lock or unlock I the door to which it is attached so that an examination of the record made will furnish information as to the time of opening and of closing and the period of intervening time.

It has for its object to provide a construc tion which-is praetically'proof against manipulation to defeat reliability and accuracy in making an unerring record however brief or momentary and expert may be the manipulation to defeat or prevent making a rec- 0rd of the opening and closing of the doors carrying the lock.

To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention primarily comprises a record receiving member, and a stylus cooperating therewith to make an inscription thereon during the period of time that the door is unlocked and in another position in relation thereto during the period that the door is locked j also in which a mark will be inscribed b y the stylus on the record receiving'member in throwing the lock-bolt in one and then in' the other direction in a practically inappreciable moment or frac- 5 tion of time and thus guard against expert manipulation of the lock with the view of preventing a perceiptlble record being made of manipulation o the lock.

More specifically stated, the. invention comprises a record-receivin member and a stylus cooperating therewitone of which travels in relation to the other and the stylus making'an inscription on the'record-receiving member in one are during the time that 5 the door is locked,'and in a different are during the time that the door is unlocked so that the period of time that the door has remained locked will be indicated by one inscribed arc and the time it has remained unlocked by the other inscribed arc, and the t1m e of locking and that of unlocking will be Indicated by the radial inscription made by the stylus in passing from one are to the ,-other.

I The invention further comprises various features and their relation one to another and mode of operation involved to effect the objects stated, all as hereinafter described and then sought to be clearly defined by the claims, reference being had to the accom-v panylng drawings forming and inwhich,

Figure l is a front elevation of a lock embodying the invention, the case or shell being in section, and parts being broken away; Fig. 2 is a side elevation, parts being in section, and the shell indicated in dotted lines; Fig. 3 is a sectional view on line 3-3 of Fig. 4, looking in direction of the arrow; Fig. 4 l; a sectional view on line 44 of Fig. 3,- on an enlarged scale; Fig. 5 is a cross-section through a portion of the shell, illustrating the formation of the door to prevent the insertion of an instrument to reach the recording devices; Fig. 6 is a face view of the record-receiving member, illustrative of inscriptions made by the stylus for the period of a week.

In the drawings, the letter A designates a train of clock mechanism of any approved type and as illustrated comprising a spring drum 1 having a toothed gear 2 meshing with a pinion 3 which transmits motion to a toothed wheel 4 meshing with a pinion 5 on a spindle 6 carrying a toothed wheel 7 which meshes with a pinion 8 on a shaft 9 carrying a toothed wheel 10 which meshes with a pinion 11. on a shaft 12 which is operatively connected with the escapement 13, all of which is of a well known construction and therefore needs nov more detailed description.

With the gear 2 meshes a pinion 14 on a shaft 15 which has a gear 16 meshing with a toothed wheel 17 having a pinion 18 attached to one side and whichmeshes with a pinion. 19 having attached to one side a pinion 20 meshing with a toothed wheel 21 having attached to one side a snail 22 upon the periphery of which bears a finger 23 connected to a rotatable sleeve 24 having at its opposite end an arm 25 carrying a marking 'point 26 and together constituting a stylus,

a part thereof,

- occasioned by said stylus being moved radially into position to describe a series of convolute circles upon a record-receiving member by reason of the change of position of the finger 23 the movement of the snail 22 derived from the clock mechanism through the several gears and pinions previously mentioned; the construction described shows seven involute curves, on one for each twentyfour hours of the day, although the invention is not limited to making the specified or any other particular number of involute curves-.-

The features so far described are in general as to arrangement and operation similar to previous constructions but difiering therefrom in the particulars presently to be described. There is also employed with the novel features hereafter described a dialplate 27 which carries the dial or recordreceiving member 28, said dial-plate by means of spring-fingers 29 being frictionally held to the toothed wheel 17 so as'to be adjustable circularly in relation thereto for the purpose of properly positioning the record-receiving member with relation to the hour of the day it is placed in position, said record-receiving member being held in place by the fingers 30 and screw cap 31, all as heretofore in timerecording locks of the type to which this invention relates. There is also employed a lock-bolt 32 capable of being moved by a key inserted in the tumbler lock 33, and also by a key coacting with a tumbler lock 34 which has a stem carrying pins working in a rack 34 as illus trated in Figs. 1 and 2, all as heretofore.

The various parts so far described in a general way are illustrated and specified for a better understanding of the preferred construction of this type of recording lock to which the present invention is illustrated as applied; the features of the present invention being given as follows. Under this invention, the stylus, the snail 22, the toothed wheel 21, and the pinions 19 and 20 are carried by a slidable or shiftable support which may consist of a plate 35 directed in its movements by any suitable guides, for instance by working in a slot 36 formed for illustration in a plate 37 from which the record-dial and other parts are usually supported, the lower portion of the shiftable support being preferably bent laterally as illustrated in Fig. 2 so as to lie within the path of an actuating lever 38'which is preferably made of bell-crank form and pivotally'sustained from the plate 37 one arm 39 of the lever lying opposite the bent portion of the support 35 and the other arm 40 standing in operative relation to the lockbolt 32 and by preferance having as a part thereof a spring or elastic extension 41 carrying a roller 42 adapted to ride on the bolt and in one position of the bolt to lie within a recess 43 formed therein. With the parts formed and disposed as specified when the lock-bolt is thrown in one direction the bell crank lever will be moved so as to shift the stylus and other parts carried by the shiftable support 35 and change the position of the stylus in its marking relation to thereoord-receiving member, and when the lockbolt is thrown in the opposite direction the shiftable support will be shifted to a difl'erent position so that the stylus will bear in a difi'erent marking relation to the record-receiving member; and thus the stylus will be caused to make a record on the dial or record-receivin member during the period of time that t e lock-bolt is in one position, and also make a record on another part or place on the dial when and during the period that the lock-bolt is in another position. Accordingly the stylus will record on the dial or record-receiving member the time when the door is locked and remains s0 and also the time when the door is unlocked and remains so, the two records being in diiferent positions on the dial and by contrast or comparison of the two records readily indicating the time and period or duration of time of each.

In the illustration given in the drawing the-invention is applied to what is known as a left hand lock, that is, one in which the bolt is thrown to the left in the locking operation and inwhich the stylus and its shiftable support is lowered when the door is locked, the same being permitted by the roller end of the bell crank lever entering the recess 43 in the lock-bolt, and the stylus and its support raised when the door is unlocked, the roller end of the lever at such time resting on the lock-bolt outside of the depression 43, so that the record is made on the dial in a higher plane when the door is unlocked than when it is locked, or in other words in one position when the door is locked and in another position when unlocked. In a right hand lock the positions of planes of the two records would be the reverse of that just described, that is, the stylus would be lowered when the door is unlocked so as to make, at such time, the record in the lower plane or position, and

raised when the door is locked and then make the record in a higher plane or position. This would be efiected by a mere change in position of the recess 43 in the lock-bolt, the recess in such case being nearer the outer end of the lock-bolt than in a left hand look, as illustrated in Fig. l of the drawing and the bolt in such case being reversed in position to that shown in Fig. 1, that is, so as to throw to the right in looking the door, all of which will be obvious to the skilled in the art without further detailed description or illustration. In either case, the invention is the same.

disk made of sensitized or unsensitized' paper and is continuously rotated by the clock mechanism, and the marking point 26 of the stylus is constantly in contact with the member so that a continuous marking or inscription. is made on the dial, such markings in the use of the snail in a seven day time lock being in the form of lines describing involute curves. These lines are made by contact of the marking point with the dial, the marking point being of metal or other suitable substance if the dial is a sensitized paper, orof a pencil or equivalent if the dial is not sensitized, so that in either case a visible marking or inscription is made by the marking point. This marking point is preferably threaded in the arm 25 of the stylus so as to be adjustable toward or from the dial, and the pressure of the marker against the dial may be regulated by an adjusting thumb screw 44 passing through the stylus arm 25, which preferably is a spring plate, and into a member.45.

A backing-plate 46 is preferably supported, in any suitable way, back of the recording dial opposite the point of bearing of the marking point against the dial to afford a back support for the dial at suchpoint. The spring 47 which holds the finger 23 against the periphery of the snail preferably is of suflicient strength to exert a downward pressure on the shiftable support carrying the stylus and other mentioned parts so as to assist the gravitation or downward movement of the shiftable support, although if desired a separate fiat or other type of spring 48 hearing against a pin 49 projecting from the plate or support 45 may be used.

In Fig. 6 of the drawing is illustrated a dial or record-receiving member showing a weeks record made by the time lock on a left hand lock, the inscribed convolution of each day showing different arcs for the convolution for the twenty-four hours of the day, the larger arcs representing the periods of time during which the door having the time-lock attachment was open or unlocked and the smaller arcs the periods of time during which the door was closed and locked. On referring to the record for Sunday it will be observed that the door is unlocked from 10.40 a. m. until 11.30 p. m. and locked day. On Tuesday it was unlocked or opened at 12.10 a. m. and remained so until 1230 a. m. and was closed and remained locked until 7'22. In. when it was unlocked and remained so until10 p. in. when it was locked and remained so until 1.55 a. m. Vednesday when,

as indicated by the small heavy black line alongside the line indicating the hour, the lock was thrown to its unlocked position and immediately back to its locked position and continued in its locked position until 7.20 a. m. when it was unlocked. It remained unlocked from that time Wednesday until 10 p. m. when it was locked. It remained so until 7 a. m. Thursday when it was unlocked and remained so till 9.15 a. m. when it was locked and continued so till 9.40 a. m. when it was again unlocked and so remained till 10 p. m. when it was again locked. It was next unlocked Friday at 7 a. m. and locked at 12.50 p. m. and unlocked at 1.20 p. m. and remained so till 10 p. m. when it was locked and at 7.30 a. m. Saturday again unlocked and so remained till 10 p. m. when it was again locked and remained so till the end of Saturday, which closed the weeks record.

From the foregoing it will be appreciated that an accurate record is made and preserved of the time of locking a door, of the time it remains locked, of the time it is unlocked and period of time it remains unlocked; and also that of the bolt being thrown into one position and immediately thrown back again, and thus a most accurate and reliable record is produced, and every manipulation of the bolt whether authorized or not is recorded. It will be further observed that the period of time that the door is locked is inscribed on one are of a circle and the period of time it is unlocked is inscribed on another or different are so that one period is readily differentiated from the other in an inspection of the record; also that the time that the bolt is thrown in one direction is inscribed or noted as well as when thrown in the other direction, and that the period of time elapsing between such operations is also inscribed by the stylus, so that the stylus makes continuously a record of such periods all of which are controlled or governed by the manipulation of the lock-bolt.

Under the invention it is not possible to defeat the purpose of the time-lock to make an accurate .and reliable record because every movement of the lock-bolt Whether much or little is inscribed on the recordreeeiving means.

The preferred construction for attaining the invention is the same whether only a daily record is made, or a record made of any number of days.

As a'protection against inserting an instrument between the casing 50 in which "that said heads will lie within the casing and fit close to the sides of the casing, and thus prevent the insertion of an instrument with which to tamper with the operative parts of the time lock.

Having described my invention and set forth its merits, what I claim is 1. A time-recording lock comprising record-making mechanism including a recordrec'eiving member and a recording stylus cooperating therewith, a lock-bolt mecha: nism including a bolt and means for positively throwing and retracting the bolt, and a member cooperatively associated with the bolt and recording-making mechanism and actuated in throwing the bolt in one direction and also inits retraction to cause the stylus to make a visible record of the movement of the bolt from one position to an other and of the period it remains in each position.

2. A time-recording lock comprising record-making mechanism including a recordreceiving member and a recording stylus cooperating therewith, a lock-bolt mechanism including a bolt and means for positively throwing and retracting the bolt, and a member cooperatively associated with the bolt and record-making mechanism and actuated in throwing the bolt in its two positions to shift an element of the recordmaking mechanism to make a radial record of the movement of the bolt from one position to another and a circular record of the period the bolt remains in each position.

3. A. time-recording lock comprising record-making mechanism including a recordreceiving member and a recording stylus cooperating therewith, a lock-bolt mechanism including a bolt and means for positively throwing and retracting the bolt, and a member located relatively to the bolt to be actuated by the bolt in its back and forth movements and connected with the record-making mechanism to cause the stylus to record in one are one position or" the bolt and in a different are another position of the bolt.

4;. A time-recording lock comprising record-making mechanism including a recordreceiving member and a recording stylus cooperating therewith, a lock-bolt mechanismincluding-a bolt and means for positively throwing and retracting the bolt, said-bolt'having a cam-formation, and a member connected with the record-making mechanism and positioned in relation to the bolt to be actuated by the cam-formation thereof to cause the stylus to make a record in one are for indicating one position of the bolt and in a different are for another position of the bolt.

5. A time-recording lock comprising record-making mechanism including a recordreceiving member and a recording stylus 7 cooperating therewith, one of which is shiftable in position relatively to the other, a lock-bolt mechanism including a bolt and means for positively throwing and retracting the'bolt, and a member connected with the shiftable member of the record-making mechanism and located relatively to the bolt to be actuated by the bolt in its back and forward movements to change the position of the shiftable member of the record-making mechanism to cause the stylus to record in difi'erent arcs the difierent positions of the bolt.

6. A time-recording lock comprising record-making mechanism including a recordreceiving member and a recording stylus cooperating therewith, a snail connected with the stylus to progressively change the position ofthe stylus concentrically to the record-receiving member, a lock-bolt and means to throw the bolt, and a shiftable member coactively related to the bolt and carrying an element of the record-making mechanism to make a radial record of the movement of the bolt from one position to another and a substantially circular record of the period the bolt remains in each position throughout the progressively changing movement of the stylus.

In testimony whereof I aflix my signa- 10E ture in presence'of two witnesses.
