EDWIN SANFORD PHELPS, 0E ELIZABETH, NEW JERSEY.

- mmn-nnconnme Locx.

Be it known that I, EDWIN PHELPS, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New J ersey, 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 a time recording lock in which a record is made of the movement of the lock-bolt to both its projected and its retracted position and also during the period the bolt remains in each position, the latter record being in ,diflerent planes for the two positions ofthe bolt so that each is clearl differentiated from the other and may be readily determined without liability of confusion.

The invention involves primarily a rotatable cylinder carrying a record-sheet and a stylus traversing the cylinder longitudinally of its axis, one of said parts being shiftable relatively to the other according as the bolt is in its projected or its retracted position and shifted in position as the bolt is thrown from one position to the other so as to make a distinctive record indicating the movement of the bolt from one position to the other as well as a distinctive record of the period the bolt remains in each position, the record for one position of the bolt being in a different plane from the record made for the other position.

The invention further involves the means for connecting the shaft of the drum to the driving or propelling mechanism so that the drum or cylinder may be rotarily adjusted with respect to the stylus without subjecting the shaft to frictional wear to bring the drum and its record sheet in proper rotation to the stylus that the latter will begin its recording action at the hour or fractional part thereof at which the device is to be set or started for making its record.

To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the features hereinafter particularly described and then sought to be clearly defined by the claims, reference being had to the accompanying Specificationof Letters Patent.

In the drawings the numeral 1 designates a casing having a door hinged at 2 provided with a lock 3 and which may also have a pivoted hook 4 and catch 5, none of which parts are claimed. Within the casing is a clock mechanism 6 of any approved type located at the top: a drum or cylinder 7 carrying a record sheet, and a marking stylus 8, located beneath and driven from the clock mechanism; and alock bolt 9 and associated member 10- for shifting the drum on throwmg the bolt, located at the bottom of the casing. The lock-bolt 9 may be .of any approved type, although as illustrated it is of that type which may be thrown by a key applied at 11, or by a key applied to turn the spindle 12 having studs 13 engaging a rack 14 formed at the top of the lock-bolt and which is a well known type. Above the lock-bolt the rotatable cylinder or'drum 7 is supported in a suitable manner, for instance by a bracket 15 attached to the backing through the arms of the bracket so as to slide therein and by which it is guided, and its lower end being stepped or journaled in a spring-plate 17 extending from the bottom of the bracket so that the drum may berotated as well as have a movement vertical or longitudinally of its axis. The upper portion of the drum shaft carries by two posts 18 a toothed wheel 18 which meshes with a toothed wheel19 attached to a worm-screw 20 journaled in the upper and lower arms of the bracket 15 and on which is mounted the stylus 8 the marking point 21 of which contacts. with a record-sheet 22 secured by clips 23 or otherwise to the surface of the threaded and thus connected to the wormscrew so that as the screw is turned the stylus will be caused to travel from the upper to the lower portion of the screw in making its markings on the record sheet carried by the drum.

The drum is rotated by power derived from the clock mechanism'G, a barrel-pinion 25 forming one member thereof meshing with a toothed wheel 26 connected with the upper part of the drum shaft 16 for the pur ose of rotating the drum. The drumsha t has a collar 27 secured thereto by a set-screw 28 and between this collar and the toothed wheel 26 is a gripping-plate or cap 29 preferably made of spring metal, and which frictionally secures or clutches the toothed wheel and the collar together so that motion is thus communicated to the drum shaft. The pur ose of thus connecting the drum shaft to tie driving mechanism is to permit the drum to be adjusted rotatively to bring its record sheet into proper relation to the stylus in setting the device for the time of day when put into operation, without disturblng the clock mechanism, and also to relieve the drum shaft of frictional wear at the point or coupling with the drive mechanism. This adjustment is effected by holding the gear 26 with the fingers of one hand and turning the drum-shaft with the other hand so as to overcome the frictional grip between the gear wheel and the collar of the shaft.

The

toothed wheels

26 and 18 being connected with the drum shaft are raised and lowered with the drum but they always remain in mesh with the barrel-pinion 25 and toothed wheel 19, respectively, they being made of proper dimensions for that purpose.

The record-sheet carrying drum is raised when the lock-bolt isthrown in one direction and lowered when the bolt is thrown in the opposite direction so that the stylus will make a record on the record sheet at the moment the bolt is thrown in either direction and also make a record in difierent planes during the period of time the bolt is 1n each position. This is effected by the following instrumentalities. Positioned between the loek-bolt 9 and the drum 7 is a member 10which for convenience may be termed a shifting dog or lever. It is pivoted at 30 and bears against the spring-plate 17 in which the lower end of the drum shaft is stepped. The shifting dog and the bolt have, respectively, one an enlar ement 31 and the other a cavity 32 which w1ll register and engage each other when the bolt is in one position, for instance as shown in Fig. 1, which is the retracted or unlocked position of the bolt and in which position the recordsheet drum is illustrated .as in its lowermost position. When the bolt is thrown into its other or locked position the shifting dog glides on the top edge or face of the bolt and is lifted so as to press against the fiatspring 17 and lift the record-sheet drum. When the bolt is retracted the shifting dog drops into the recess in the bolt and awa from the flat-spring 17 and the record-she t drum then again assumes its lowermost position. It will thus be observed that the stylus will make a record on the sheet carried by the drum at the moment the bolt is thrown in either direction, such marking being in the direction of the axis of the drum, and will also make a record during the entire period that the bolt remains in each ofv hour with the hour rulings designated numerically, and the a. m. and p. m. period appropriately designated as shown in the drawing. The marking for the days however are made solely by the stylus and will be made by it circularly or annularly around the circumference of the'drum, and will be made spirally as the stylus travels from the top to the bottom of the drum or recordsheet.

The worm screw carrying the stylus will make one revolution for each revolution of the drum and thus one convolution will be marked on the record sheet for each 24 hours or day. By observing each marking made longitudinally of the axis of the drum and its relation to the hour and fraction of hour when made it will be apparent at what time the bolt was thrown to its looked as well as its unlocked position and the number of times it was so actuated, and observation of the convolute marking will indicate the length of time it remained in each of such positions. The marking point 21 may be either a lead or a metal point so as to mark upon the record sheet whether the latter be a sensitized paper or not.

One record-sheet may be replaced .by another whenever necessary. At such times it is desirable to throw the stylus away from the surface of the record-sheet drum. For that purpose and to hold the stylus in its thrown back position'and also to enable it to be snapped back into recording osition, the rear of the stylus is connected with a guide-rod 33 preferably by formin a fork 34 to the stylus to straddle said ro This rod is made in the form of a crank rod and suitably journaled, as illustrated, and a suitable sp in 35 is caused to exert its tension on the r so as to hold the rod in the two positions to which it may be thrown by the stylus as the latter is thrown into its operative or its inoperative position.

The advantages of the invention as described will be obvious to the skilled in the art, and the operation will be obvious from the foregoing without further description. It will also be obvious that while the preferred details are illustrated and described, changes can be made in the details and essentialfeatures of the invention retained.

Having described my invention and set forth its merits what I claim is 1. A time recording lock comprising recording-mechanism including a rotatable drum and a. recording stylus one of which isshiftable longitudinally of the axis of the drum, the stylus being in contact with the drum to inscribe a'record during the period while the bolt is in both its locked I and unlocked positions, and means cooperating with the bolt and shiftable member of the record-making mechanism to shift the latter member to change record from one plane made while the bolt is retracted to another plane made while the bolt is projected.

2. A time recording lock comprising record-making mechanism including a rotatable record-carrying drum and a stylus movable relatively to the drum, a lock-bolt, and means cooperating with the bolt-to shift the drum longitudinally of its axis when the bolt is in one position.

3. A time recording lock comprising record-making mechanism including a rotatable record-carrying drum and a stylus movable .relatively to the drum, a lock-bolt, means cooperating with the bolt to shift the drum longitudinally of its axis when the bolt is in one position, and spring influenced means associated with the stylus to hold it retracted when thrown away from the record-carrying drum.

4. A time recording lock comprising record-making mechanism including a rotatable record-carrying drum and a recording stylus movable relatively to the drum, a lock-bolt, a spring-support for the drum, a lever cooperatively associated with the lock-bolt and adapted to be actuated by the bolt to throw it against said spring-support to shift the drum to change the plane of contact of the stylus therewith.

5. A time recording lock comprising record-making mechanism including a rotatable record-carrying drum and a worm shaft parallel with the axis of the drum and one of which is shiftable longitudinally of the other,

a recording stylus traversing the worm shaft, a lock-bolt, and means intermediate of the bolt and the recording mechanism and actuated by the bolt to move the shiftable member of the recording mechanism to change the plane of the record.

6. A time recording-lock comprising recording mechanism including a rotatable record-carrying drum capable of movement longitudinally of its axis and a worm shaft carrying a recording stylus to traverse the drum longitudinally of its axis, a clock mechanism for rotating the drum, and a frictional clutch coupling between the drum shaft and clock mechanism for adjustment of the drum.

In testimony whereof I aflix my signature in presence of two witnesses.
