WATC H MANS TIM E- DETECTE R.

SPECIFICATION forming part of Beissued Letters Patent No.

9,887, dated september as, 1880.

Original No. 172,630, dated January 25. 1876. Application for reissue filed June 15, 1880.

To all whom it may concern:

Be it known that I, WILLIAM IMHAEUSER, of Brooklyn, in the county of Kings and State of New York, have invented an Improved Watchmans Time-Detecter, of which the following is a specification Figure 1 is a top or plan view of my improved watchmans time-detecter, showing the lid folded open. Fig. 2 is a vertical section of the same closed, the line 0 c, Fig. 1, indicating the plane of section through the lid. Figs. 3 and 4 are plan views of two of the keys used therein.

Similar letters of reference indicate corresponding parts in all the figures.

This invention has for its object to improve and simplify watchmens time-detecters'of the class containing a rotaryv dial or paper disk; and it consists more particularly in placing within the folding lid of the instrument a hammer or pointing'or marking instrument which is capable of vibrating in two directions, as hereinafter more fully described.

Similar devices have beeupreviously used in the bodies of the time-detectors beneath the I rotating dials or disks; but I have found that by placing these doubly-movable markingdevices into the lids above the dials or disks the construction of the time-detecter is materially simplified, and that the parts are readily inspected and exposed to view by merely opening the lid, and are therefore also less liable to interfere with the clock-work from which the dials or disks receive their rotary motion.

The invention also consists in combining said hammer or marking-instrument in the lid of the instrument with the carrying-bar to which said hammer is attached and with which it moves horizontally in conjunction.

The invention also consists in providing said bar with a lug which straddles the key-arbor, and against which the keys are pushed to determine the position of the hammer at the time the mark is to be made.

In the drawings, the letter'A represents the body or case of my improved time-detecter, and B the lid or cover of the same. The lid is usually hinged to the body, or otherwise so connected that it can be folded open, as in Fig. 1 or taken off to expose the paper dial or'dis O to view. This paper dial ordisk is, as usual, removable, and is for use secured within the shell A upon a rotary plate orholder,

to which rotary motion is imparted by clockwork concealed within the shell. When the lid is closed down upon the shell, as in Fig.2, it is locked thereto by a suitable lock, and can be unlocked by a suitable key.

D is a bar attached to the under side of the lid B by a pin, a, and connected with a spring or vibrating hammer, b. The bar D is capable of motion in a horizontal direction, while the spring or hammer b is also capable of be- Each key of the series pertaining to one iustru ment has a bit, 0, differing in length from the bite of every other key'of the same series, and has also a shoulder, f, as shown. The shoulder f of one key is as far from the bit of such key as the shoulder f of every other key of the series is from its respective bit, yet, the bits varying in length, it follows that the distance between the shoulders and ends of the keys varies in all the keys.

The lid B is perforated to form a key-ho1e,as at 9, through which the keys can be successively introduced. The I key, when inserted through the key-hole, fits upon the arbor j, which is secured to the inner side of the lid, and which arborisstraddled or embraced by a perforated lug, h, which is attached to the bar D, as is clearly shown in Fig. 1. Each key is pushed, when insertedinto the key-hole, until its shoulder f strikes the lid, the end of the key meanwhile striking the lug h, and thus the key moves the bar D horizontally against a spring, 1', and by such motion also moves the hammer b horizontally until the marking-point d is over that portion of the dial which it is to mark. In the normal condition, and before a key is insertedgith'espring 1' holds the bar D against a stop, lfwhich is securely placed into the lid, as shown in Fig. 1. As soon as the key hasbeen properly introduced it is turned on its arbor j so that its bit will come in contact with the spring or hammer b, and thereby vibrate the latter vertically to throw or press its pointer or marker (1 into contact with the paper dial or disk (3. A mark is thus made in the dial, indicating the time the key was introduced, and, by itsdistance from the center of the dial or disk, the key with which the mark was made.

The paper dial, when used, may be subdivided by radial curves and also by concentric rings in the usual manner, and, as indicated-in Fig. 1, when, in place of the paper dial, a blank-paper disk is used, a row of types or dies will have tobe secured in the case A, directly beneath the disk, to afl'cct the paper when the same is pressed upon them by the marker or' pointer d. I

I am aware of Patent'No. 138,084, which has a piercing-tool placed'into the body of the in-,

strument. Said device is not capable of application to a lid without slotting the top plate of the works and entering the pin therein, and

imitated.

produces, moreover, a mark which is easily bination of the lid or cover B with the horiwith the projecting log k and key-arborjysnbstantially as hereinshown and described.
