'IMPROVEMENT'IN WATCHMENS TlME-DETECTERS.
Specification forming partof Letters Patent No. 196,913, dated ovember 6, 1877; application filed October 22, 1877.
To all whom it may concern:
Be it known that 1, WILLIAM W. LE GRANDE,Of Louisville, in the county of J efferson and State of Kentucky, have invented certain new and useful Improvements in atchmens Time-Detectors; and I do hereby declare that the following is a full, clear, and exact description thereof, which 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 of referei'ice m arked thereon ,Zwhich form a part of this specification.
My invention relates to watch'mens timedetecters; and it consists in certain improvements thereon, as will be hereinafter more fully set forth, and pointed out in the claims.
In the annexed drawings, which fully illus-' trate my invention, and to which reference is made j Figure l is a front view of my improved watchmans time detecter' with the front thrown open. Fig. 2 is a section of the same with the front closed. Fig-3 is an enlarged detailed view of the locking device for the front of the time-detecter. Fig.4 is an inside view of the glass front with spiral in glass; and Fig. 5 is a section of the same on the line 00 00, Fig. 4. I
Heretofore watchmens time -detecters have been made with a series of keys to work the registering devices. This is'objectionable, as the keys can readily be connterfeited, and if a watchman or other person has in his possession a duplicate key for lockin g or working in any way a registering time-detector, such detecter is thereby rendered worthless for the purposes for which the same is intended.
Time-detectors are also made to lock up with a key inserted in a key hole in the usual manner. This, also, is objectionable, as clocks and watches for this purpose are generally -made of light material, and, consequently, when left with a hole in them, are not infallible time-registers. It is also troublesome to find keys, and to place them in proper position for working a time-detecter at night entails trouble, and consumes valuable time of the watchman.
Another serious objection to the time-detecters now in use is the handling of the movement daily in order to change the devices, which is liable to retard the movement of the train.
The object of my invention is to obviate these and other difficulties, and provide a watclnnans time-detecter that shall possess the followin g novel features and improvements: First, a watclnnans time detecter or register that will run eight days or more without be ing opened or changed; second, that is automatic in changing the registering device from day to day as long as the clock is in motion; third,that has no key or key-hole; fourth, that is securely locked by closing the door; fifth, that is unlocked by the clock-movement at any time required within the term of the movement; sixth, that will answer the purpose of a timepiece for a factory orother place by day and a time-detector by night; seventh, that will show at a glance the time each night and morning that a watchman or other person comes on or goes off duty during a week back or more; eighth, that cannot be unlocked until the expiration of a fixed time.
To accomplish these objects the clockmeclt anism A, of any suitable construction, is arranged with an eight-hour or pendulum movement, in a suitable case, B.
The dial 0 is raised in the center, as shown, to receive a disk, D, of paper or other substance, held in place on the dial by arim, a,
as shown. To the hour-wheel A of the clock mechanism is secured a cross-bar, b, with two pins, b 12 forming a double verge; which projects upward through the dial to receive the the disk D by means of a pin, z, projecting inward from the hand.
On the center of the glass front H is pressed or cast a sleeve, k, in which a spiral spring, f, is placed, and through which the button E is passed. Around this sleeve, on the inner surface of the front H, is pressed a spiral groove, I, to receive guide-pin, is", which is" fixedin the hand G, and works in said spiral forthe purpose of pushing the hand endwise during its circuit over the dial, thereby giving it a moved in a radial line by the clock-train while new circuit to go over each day.
The spiral in the glasseorresponds ingd'iame ter t0 the raised surface on the dial; hence the registering-pin i will, when the hand is d-e pressed, puncture in "a new circuit each day until the guide-pin c has traversed the length of the spiral guide. Thisoutward movement of the hand, giving the punctiu'ing -pin a new nected to the glass front of the clock, and opcircuit each day,requires only one disk, D,
per week or during the time the clock will run,
thereby obviating the necessity of disturbing theclock daily, as is, customary with .time deteeters now in use.
The sleeve k and spiral guide I may be separate and attached to the front H, as representedin Figs. 1 and 2;; but they are pref-j era-lily pressed in or cast with the front in one piece.
changed.
Above the lever-latch J is pivoted .a second lever, L, with 'a'weigh-t upon its end, and two? notches, isc', in the lower edge to hold the latch in proper position, so that when the sash is closed the catch m won the sash w1 ll, by-com-- ing in -:contact with the hevelededgezof the latch J, push it :out of the way until the notch in said catch m receives the latch.
Thewei ghted-leverlirests withth'e firstnotch s 5011 the end of the curved arm n, and thereby 5 holds the'latch securely in the notch of the; catch until the registering-han dGrstrikes apin,
t,pro 'ectingfrom the latch 3 when it-movesup,
and the arm n raises the lever L- until the-end thereof catches in the second notch -s., thus holding it unlocked until the inv charge I my own I have hereto affixed :my.-si-gnature in of the clock eanihave time to readjust it.
It being understood that the clock is fixedto a wallipermanently, it will readil-y be seen that no access can be hadito the ragistering device until the time for which it may he :adjusted-sa-y, :every eight days ;.or more.
T:he hand connected to the glass front, is not in the way when the disk is being Having thus fully described my invention,-
what lclaim as new, and desire to Letters Patent, is'
1. In watchmens time-checks, a graduallymovingregistering-hand that is automatically erated by an exterior spring-button for puncturing the disk, substantially as herein set forth.
4. The combination of :a radially-sliding registering-hand, provided a projecting guide-pin, and a spiral guide attached to or formed on the inside :ofv the glass front, for
the purposesherein set forth.
5..The .:eomhination of :a radially-slidingreg isterin-g-hand, :a clock mechanism for rotating the same, and a spiral guide for sliding it radially, substantially as herein set forth.
. f6. lnr'a-watchmaifls timedeteeter a docking" device forflocking the clock automatically and unlocking the same by the'act'ion ofthe'regis' tering-ha-nd, substantially as herein set forth.
7. The 'comhination of a rotating :and radially-sliding registering hand and :a locking.
a spiral guide, a rotating and radially-sliding registering-hand, and an automatic locking device, substantiallyras and for the purposes herein set forth. I
