CHARLES E. SANFORD, OF NEW? YORK, ASSIGNOR TO RICHARD HARPER LAIMBEER, OF BROOKLYN, N. Y.

WATCHMANS REGISTER.

SPECIFICATION forming part of Letters Patent No, 261,388, dated July 18, 1882.

Application filed October 1-2, 1881. (No model.) I

To all whom it may concern;

Be it known that I, CntARLEs E. SANFORD, of the city, county, and State of New York, have invented a certain new and useful Improvement inVVatchmens Registers,of which the following is a full, clear, and exact description.

Reference is to be had to the accompanyingdrawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of my improvement, shown with the box-door open. Fig. 2 is a sectional side elevation of the same, taken on the line 00 a", Fig. 1, the door being shown closed. Fig. 3 is ascctional plan view of a part of the same, taken through the line 9/ y, Fig. 2. Fig. 4 is a sectional plan view of a part of the same, taken through the line .2 a, Fig. 1.

The object of this invention is to improve the construction of the watchmans register for which Letters Patent No. 113,988 were granted to James Dunning, April 25, 1871, in such a manner that the markerwill change its position automatically each day, and also in such a manner that the door of the register cannot be opened until the time for which it was set has expired.

A represents a box of convenient size, and which is provided with a door, B, in front,and is divided into two compartments by a partition, U,placed parallel with the said door B.

in the rear compartment of the box A is placed an ordinary eight-day clock-work, D, the hands of which are removed and the hourhand pivot E of which projects through a hole in the partition 0 and has a dial-plate, F,

placed upon it, so as to be carried around by and with the hour-hand pivot E in its revolution. The face of the dial-plate F is divided into seven concentric ringspaces, as shown in Fig. 1, which spaces can be marked with the names of the days of the week, if desired. The ring-spaces of the dial-plate F are divided into twelve equal parts by radial lines, as shown, which lines can be marked with the numerals from 1 to 12, consecutively.

To the end of the pivot E, or to a disk or plate secured to the said pivot, is attached ec centrically apin, G, which at each revolution of the pivot E, and consequently once each twelve hours, comes in contact with a tooth of the gear-wheel H, and turns the said gearwheel through the space of one tooth.

The gear-wheel H, is pivoted to an arm or frame, I, attached to the inner side of the door B, and which is made with an offset to bring the gear wheel to a little distance from the door B.

The gear-wheel H is held from being turned any farther than the space of one tooth by one contact of the pin G by a spring, J, having a wheel, K, pivoted to its free end to rest upon the teeth of the said gear-wheel H. The other end of the spring Jis connected with the frame I by a short stud, as shown in Fig. 2; or the spring J can be replaced by a pivoted rigid arm and the wheel K held against the gearwheel H by a spring, J, attached to the said arm and to the door B,all as shown in Fig.1.

To the pivot of the gear-wheel H, at the inner side of the said gear-wheel, is rigidly attach ed a scroll-plate, L, so that the said scrollplatc will be carried around by and with the said gear-wheel. The edge of the scroll-plate L is formed of a number of arcs, each succeeding are being nearer the pivot of the said plate than the one before it.

Upon the edge of the scroll-plate L rests a pin, M, attached to the plate N, which slides up and down upon a bar, O, attached to the door B, so that the said plate will move down as the scroll-plate L is revolved, and the pin M passes successively from one to another of the arcs of the said scroll-plate L.

To the plate N is attached a tube, P, which passes through a slot in the door B, and has a plate, Q, attached to its outer end, which slides up and down upon the outer surface of the door B.

The plate Q, is made of such a size as to cover the slot in the said door B, and can be plain or ornamented, as may be desired.

Within the tube 1? is placed a pencil-holder, R, the inner end of which is tubular to receive a pencil, S, and its outer end is squared or recessed to receive the key T, by means of which the pencil-holder R and pencil S are pressed inward and made to mark the dial F. The pencil S is held in a horizontal position by passing through a hole in a bar, U, the ends of which are bent inward and then outward, and are attached to, the plate N. The pencil S is drawn back after being pushed forward to mark the dial F by a spiral spring, V, placed upon the said pencil, with its forward end resting against the guide-bar U and its rear end restingag'ainst the end of the holder R.

If desired, a pin, W,-can be attached to the holder R to enter a spiral slot, X, in the tube P, so that the pencil-holder R must be turned by the key T to cause the pencil S to mark the dial F. This arrangement prevents the pencil from being pressed inward to mark the dial by any other instrument than the proper key.

The plate N and its attachments are kept from being raised from the outside of the door 13 by a spring-pawl, Y, pivoted to the said plate N, and which engages with the teeth of a ratchet-bar, Z, attached to the said door B, as shown in Fig. 1.

The doorB is secured, when closed, by a spring-catch look, a, so that the said door will be locked automatically when swung shut, and can be unlocked only by a key. The lock ais set out from the door B a little, as shown in Fig. 4, so that a plate, I), can be slipped in between the said lock and door to cover the keyhole of the lock and prevent a key from being inserted.

To the outer end of the plate b is pivoted the end of a bent lever, c, which is pivoted to the doorB and is weighted, or has a weight, d, or weighted arm attached to it in such a manner as to turn the said lever c and draw back the plate I) when the upper end of the said lever c is released.

In the upper end of the said lever c is formed, or to it is attached, a vertical socket, e, in which is adjustably secured, by a set-screw, f, a rod,

g. Upon the lower part of the rod g are formed a number of division marks at a distance apart equal to the width of the ring-spaces of the dial F.

To the sliding plate N is attached the inner end ofa rod, h, in the outer end ofwhich is formed an eye to receive the lower part of the rod g. With this construction, as the plate N and its attachments move downward the rod h slides downward upon the rod 9, and as it passes off the lower end of the said rod 9 the lever c is released and is turned by the weight at to draw back the plate b and uncover the keyhole, allowing the look a to be unlocked and the door B to be opened. The division-marks upon the'rod 9 allow the said rod to be set in such a position that thelever will be released at the end of one, two, or any desired number of days.

By using an eight-day clock-work the box will not need to be opened oftener than once a week, when the dial F-cau be detached and replaced with another dial, and the box again closed for another week.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- 1. Thecombination,with thehour-hand pivot of the mechanism of an eightday clock, projecting through box-partition O and carrying an end crank pin, G, of the gear-wheel H, having sixteen teeth and acted upon by springheld wheel K, the scroll L, rigidly attached to wheel H and having its edge divided into sixteen arcs successively approaching nearer to the center, and the vertically-movable pencil-ear rying plate N, having the stud M resting on said scroll, whereby the pencil will be daily lowered so as to mark opposite to a different day of the week, as notated on the dial-plate F.

2. The combination, with the lock aand mov able pencil-carrier N, of the sliding plate I), the weighted lever t, the adjustable gage-rod g, and the eye-rod h, whereby the key-hole will be uncovered automatically at the end of a fixed time, as set forth.
