RECORDER.

SPECIFICATION forming part of Letters Patent No. 704,925, dated July 15, 1902.

Original application iiled October 2, 1901, Serial No. 77,323. Divided and this application filed November 27, 1901. Serial l No. 83,945. (No model.)

To al?, whom, it may concern:

Beit known that I, CHRISTOPHER J. RoAcH, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Recorders; and I do hereby 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.

This invention relates to improved means for automatically recording the time at which any one of a series of circuit-closing locks or their equivalent is operated.

The primary object of the invention is to provide a simple and highly-eflicient recorder for use in conjunction With a series of electrically-connected locks of the character outlined in my applicationfor patent led October 2, 1901, Serial No. 77,323, of which this is a division. In that application I showed and described a system of locks for mail-boxes, the several locks being electrically connected in series, to the end that they may be opened only successively. lt is important that the fact and time of opening each box of the series should be indicated or recorded at a central point-as, for instance, at the post-office of the district to which the several botes belong.

The present invention has reference to the means for recording the opening of each box within the series of which the recorder forms part, and means comprehending such improvements will hereinafter be fully described, and the invention will be particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of the recorder, a portion of the dial being broken away. Fig. 2 is a longitudinal sectional View on line 2 2, Fig. 1, the clock mechanism being omitted. Figs. 3 and 4t represent two locks in 'conjunction with which the recorder may be used, the coverplates of the locks being omitted. Fig. 5 is an enlarged detail.

Referring to the drawings, 1 designates an inclosing case wherein is located a magnet 2, which is in circuit with a series of locks connected in series, two of such locks being indicated in Figs. 3 and 4. The armature 3 of magnet 2 is connected by a spring et to a 'lever 5, fulcrumed at one end. At its free end this lever carries a pawl 6, adapted to engage a ratchet-wheel 7, mounted on arbor S. Also upon this arbor is a gear-pinion 9, having a segmental `toothless or smooth portion 10, equal in length to the space of two teeth. This gear-pinion meshes with a rack-bar 12 and effects the longitudinal movement thereof in one direction. On one end of this rackbar is mounted a small cylinder or housing 13 of a punch or marker 14, having a collar 15, engaged by a spring 16, which serves to normally hold the punch or marker withdrawn. Upon an arm 17, projecting from rack-bar 12, is fulcrumed a bell-crank lever 1S, one arm of which is designed to engage the punch and force the same outward as against its spring when the other arm of the lever is engaged by an extension 19 of armature 3.

A paper dial 20 is designed to be actuated by suitable clock mechanism (not shown) located within a chamber 2l. (Shown in Fig. 2.) This dial is divided into twelve equal parts, representing the hours, While the subdivisions of each part represent iive minutes each.

The energizing of magnet 2 will attract armature 3, causing lever 5 to move suflioiently to effect the turning of ratchet-wheel 7 the extent of one tooth, any further movement of the lever being limited by a stop 22. The turning of gear-pinion E) in conjunction with the turning of the ratchet-wheel will move rack-bar 12 toward or over one face of the paper dial. When lever 5 is brought up against stop 22, the spring a will allow the armature to move to its magnet, and in doing so the extension 19 thereof Will engage lever 1S and actuate the same to cause the projection of the punch and the forcing of the point thereof into or through the dial, thus recording the time at which a mail-box is opened and indicating by the number of punches at the end of the operation of the entire series the exact time at which each box thereof was opened. A bar v23, (shown broken away in Fig. 1,) extending over one face of the dial, serves as an anvil or resistance of the punch to prevent tearing the paper. As soon as the punch has performed IOC its work the circuit will be broken and the spring 4 will return armature 3 to its normal position, the lever 5 likewise resuming its normal position, and the spring 16 will again Withdraw the punch.

One revolution of gear-pinion 9 determines the eXtreme forward movement of rack-bar 12, so that when the segmental toothless portion l() is brought into contact with the rackbar the latter will be thrown out of engagement with the teeth of the pinion. Thereupon coil-spring 22 f, attached to the out-er end of the rack-bar, will return the latter to its starting-point in readiness for a second operation. `When, therefore, the circuit is first closed, as upon the opening of the first mail-box of the series, the segmental toothless portion of pinion 9 will be caused to move out of engagement with the rack-bar without advancing the position of the latter and at the same time the first hole in the dial will be made. When the circuitis next closed, the bar will be then moved forward the eX- tent of one tooth, as before described. A dog 24 prevents the backward movement of the ratchet-Wheel and pinion when the rackbar is being returned to its starting-point.

To the end that the use and application of my present invention, in conjunction with the system for which it is specially designed, may be understood, I have illustrated and shall now describe the general features ofthe mail-box locks.

Each lock is the duplicate of the other; but the controlling mechanism of all the locksthat is, the means which allows them to be opened or operated-is differently set and relatively arranged so that all the locks in a series must be successively actuated-that is, in a step-by-step order. The description of one lock will apply to all. In each lock is a magnet 25, the armature 26 of which is connected to a lever 27, which carries a pawl 2S, engaging a ratchet-Wheel 29. Fast to this ratchet-wheel is a tumbler 30, having a notch 3l, which, when in line with a lever 32 on the locking-bolt 33, allows the latter to be withdrawn. A trip-lip 34 of the tumbler engages a circuit-closing lever 35 for breaking the circuit when the tumbler-notch is in line with lever 32. The relative arrangement of the controlling mechanism of the several locks is s uch that when the trip-lip of the first lock acts on its circuit-closer the trip-lip of the second lock is moved a point nearer its contact-lever and a corresponding movement occurs in all the remaining locks. Upon the insertion of a key in the first lock bolt 33 thereof may be withdrawn or turned back, its tumbler-notch being in line with the bolt-lever, and upon such withdrawal of the bolt the pin 36 thereof engages a second circuit-closer 37, thereby restablishing or again closing the circuit previously broken through the circuit-closer 35. Thus the ratchet-wheels of the several locks will be again rotated the extent of one tooth, and the second lock of the series may then be operated upon the insertion of a key; but the locks of the series must be opened successivel y, beginning with the first and ending with the last. The number of the teeth of ratchet-wheel 7 of the recorder corresponds to the number of ratchet-teeth of wheels 29 ofthe lock-controlling mechanisms, with which it is designed to move in unison. In the drawings the ratchet-wheel 7 and the ratchet-Wheels 29 are shown as equipped each with twenty-folli' teeth, representing twenty-four boxes comprised within a series or district. If a lesserl number of boxes be used than there are teeth in the ratchetwheels,such wheels canbe made to travel a greater distanceat each operation. For instance, if there were but six boxes the wheels could be made to travel the extent of four teeth at each operation. It is not necessary,therefore, to substitute different ratchet wheels. In practice each time one of the locks of the series is actuated by the withdrawal of its bolt the circuit in which the magnet2 of the recorder is included will be established the latter will be actuated and the fact and time of such operation of the lock will be indicated, the dial being moved by the clock.

`No claim is herein made to the lock mechanism or to the system independently of a recorder, since the same forms the subjectmatter of my before-noted application for patent.
