Application filed April 20, 1910. Serial No. 556,539.

T 0 aZZ whom it may concern:

Be it known that I, Bonner Korr, a citizen of the United States, residing at Belmar, county of Monmouth, and State of New Jersey, have invented certain new and useful Improvements in Time-Recorders, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to that class of time recorders or watchmens detectors having a suitable case with a time-card rotated by the The keys, as is necessary, are made with bits of different lengths, adapted to shift the sleeve upon the spindle and to also shift the slide and hammer-spring, through the engagement of the sleeve with the bearing upon the slide.

The invention will be understood by reference to the annexed drawing, in which- Figure 1 is an edge view of the case with a cover shown in section thereon and the hammer-mechanism viewed from the arrow 1 in Fig. 2, which shows the interior of the clock-movement, and a spring-hammer cover. Fig. 3 is a section on line 3-3 in adapted to mark the tnne'card when suit- Fig. 2; Fig. 4 shows the cover in section ably actuated by a key. with the hammer-mechanism vlewed from The hammer in this device is mounted upon a slide in the cover of the time recorder to move radially of the time-card, and a series of keys to be used at different stations is provided with bits of different lengths so that when inserted through a hole in the cover they may shift the slide and the hammer to different distances from the center of the time-card and then actuate the hammer to impress the card. Heretofore, the keys have been simply inserted through a key-hole in the cover, and the bit upon the key has been used as the agent for directly actuating the spring which carries the hammer; but it is very easy to counterfeit such keys, and the object of the present invention is to use keys which are difficult to duplicate, in conjunction with a separate device for actuating the hammer intermediate to the key and the hammer-spring, so that the key shall operate only indirectly in marking the card.

The invention is shown in connection with a Yale lock having a rotatable barrel with a longitudinal slot at one side, and a key adapted to actuate tumblers which hold the barrel normally from rotation.

The intermediate mechanism consists of a spindle extended axially from the inner flange of the barrel parallel with the slide which carries the hammer-actuating spring, and having a sleeve longitudinally movable upon the spindle and journaled upon thej slide and carrying a dog adjacent to the j the arrow 4 in Fig. 2; Fig. 5 shows the cover in section at the center of the spindle with the hammer-mechanism viewed from the direction of the arrow 5 in Fig. 2; Fig. (3 shows the inner side of the lock-case with the ratchet-mechanisin; and Fig. 7 is a partial plan of the cover showing the lock, the slide and the parts connecting the lockbarrel and the slide.

The case is designated A, and the cover B jointed thereto by a hinge C, which cover in practice is held closed upon the clockcase by a hasp D and locking mechanism.

The slide a is mounted in ways I), Z) within the top of the cover and has a block at one end to which the hammer-spring c is fastened and provided at the opposite free end with the hammer-head (Z.

A lug c at the side of the ham1nerhead is provided to engage the rotating dog f actuated by a spindle Z.

A Yale lock-case Z2, is secured within the cover adjacent to one end of the slide and a spring 71 draws the slide normally toward the lock-case. A barrel is fitted within the lock-case and is provided with a flange 70 upon its inner end and a flange Zc upon its outer end, the inner flange having a square socket in the center to receive the end of a spindle Z. The barrel is provided as shown in Fig. 7, with tumblers m and the key is shaped with teeth at to shift the tumblers so that the barrel may be rotated.

A sleeve 11. upon the spindle Z is journaled in a bearing 0 projected from the end of the slide near the level of the hammerspring 0 adjacent to the lug 0 upon the spring, and the dog is attached to the sleeve to rotate therewith. The sleeve is hammer-head for snapping the spring to actuate the hammer. This spindle and sleeve can only be rotated by turning the barrel which in turn can only be revolved by a key adapted to shift the tumblers.

shoulder 79 at the end next and the spindle adjacent to the dog 7 1s squared, as at Z, and fitted to a square hole in the dog so as to rotate the dog when the spindle is turned.

The outboard end of the spindle is fitted to an outboard-bearing in a screw-plug Q fitted removably in the wall of the cover and having a central hole to receive the rounded end of the spindle. The withdrawal of the screw-plug permits the spindle to be slipped out of the socket provided with a the lock-easel,

endwlse 1n the barrel j. This serves as a means of connecting or disconnecting the hammeractuating mechanism with the barrel in assembling the parts of the device. The sleeve, owing to the arrangement of the parts is of considerable length, and is made with a cylindrical bore to fit the spindle loosely and adapt it to pass over the squared portion of the same, which is fitted only to the dog f'.

In Fig. 2, a ke g is shown inserted through a slot it the barrel j, with a bit 9 of sufficient length to push the spindle away from the lock about a quarter of an inch, thus moving the slide and the hammerhead that distance from their innermost position.

The parts are shown in the same position in Fig. 4; but in Fig. 5 the slide is shown retracted and the sleeve in contact with the flan 'e 70.

Fig. 2 shows the dog in position for the withdrawal of the key, and as such a key can only be withdrawn when the barrel is in its initial position, it is evident that the dog cannot be turned or the hammer actuated except by a key, which will shift the tumblers and permit the rotation of the barrel.

Figs. 1 and 4 show the dog rotated and the spring partially depressed thereby.

Fig. 7 shows the l'ock-case in section adjacent to the barrel as well as the barrel, the sleeve, and the bearing which sustains the sleeve upon the slide.

The bit of the key is not adapted to operate upon the hammer-spring, but the hammer-actuating mechanism is separate from the key and intermediate to the lock and the iammer-spring.

To prevent the turning of the dog backwardly, the flange is is formed with ratchet notches, and a pawl r is pivoted upon. the lock-case and pressed normally toward the notches by a spring Z. One of the notches is arranged, when contacting with the pawl to set the barrel in exact position required to insert or withdraw the key; thus aiding the operator to set the barrel in the right position, which is effected by turning the barrel backwardly if turned beyond its normal position.

One of the ways 6, o, is made longer than the slide and has a stopbar t at its farther end. This way is secured to the I cover by screws 41. The opposite way 5, as shown in Fig. 2, is made shorter and secured to the bot-tom of the cover by screws 71.

lVhen the key is removed from the slot it the slot forms an opening from the exterior to the interior of the cover B, and any object passed through the slot can move the sleeve lengthwise upon the spindle Z, but is incapable of rotating the same to actuate the hammer until the bar el is unlocked by which the spindle is controlled.

A suitable key to actuate the tumblers is necessary for the rotation of the barrel, but even then the key is not the direct instrument for actuating the hammer, but the spindle and sleeve form the intermediate agencies; the spindle being immovable longitudinally and the sleeve being shifted upon it by the various keys in the series employed to impress the time-card at different distances from the center.

It will be understood that of the hammer-head to a spring enables the hammer to strike an instantaneous blow, and at once recede from the time-card so that it does not act as a brake or in any de gree retard the clockmovement, or lacerate the card.

I A safety knife is shown at 3 in F 2 and 4;, which is commonly used in such timedetectors to cut through the edge of the card when the cover is closed upon the case. The hammer upon such safety knife operates when the cover is opened to cut the card in a different place, owing to the rotations of the card in the interim, and if more than two of such knife cuts appear upon the edge of the card, it indicates that the cover has been opened surreptitiously.
