TIME-CLOCK FOR CASH-REGISTERS.
SPECIFICATION forming part of Letters Patent No. 790,654, dated May 23, 1905.
Application filed August 20, 1900. Serial No. 27,417.
To (Li/Z 1077 0771 it may concern:
Be it known that I, FRANoIs C. OSBORN, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Time-Clocks for Cash-Registers; and I 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 pertains to make and use the s-ame,ref erence being had to the accompanying drawings, which form a part of this specification.
My invention relates to improvements in time-clocks for cash-registers, and is shown in the accompanying drawings, in which Figure 1 is aview of a cash-register with a clock in place in the register. Fig. 2 is a horizontal cross-section showing the manner of supporting the clock in the case. Fig. 3 is a rear view of the supporting-plate, showing the winding-key exposed and the setting-key in dotted lines to represent the same as covered. Fig. 4 is a section on line 00 m. Fig. 5 is a sectional view of the setting-plunger from line 3/ y of Fig. 4. Fig. 6 is a view showing the cam for lifting the plunger. Fig. 7 is a detail showing the construction of the hour-hand, and Fig. 8 is a detail showing the construction of the third hand.
In the drawings. A represents the case of the register, and A an upstanding ornamental plate on the top of the register. In machines with which the time-clock is used this plate is provided with a recess a of a size to receive The depth of the recess is usually less than the depth of the clock, so as to allow the clock to stand out a suflicient distance to provide for operating the plunger D in front of the plate A. This form of construction is not necessary, however, as a recess may be provided for the plunger in the through an opening 0/ in the rear wall of the recess a. This form of construction is to provide for winding the clock without removing it from the recess, which can only be done by the person holding the key, usually the proprietor.
represents in dotted lines the setting-key, which can only be operated by unlocking and removing the clock.
The opening through which to operate the winding-key may be dispensed with where the proprietor does not object to unlocking the clock for the purpose of winding.
C represents an interior plate, in front of and upon which the additions to the usual clock mechanism employed by me are supported.
C is a frame which forms a hearing at c for the journals to which the hands are attached. The frame also constitutes a support and guide for the plunger D.
e is the sleeve to which the hour-hand 0 is attached, and 0 the journal to which the minute-hand 0* is fixed.
0 is a double-faced cam sleeved upon the bearing 0.
0* is a third hand attached to the sleeve 0 The sleeve 0 is integral with the cam c and is allowed an end wise movement with the cam, by which endwise movement it carries the third hand 0* to or from the hour-hand, which stands next to it. The sleeve 0 is mounted with such closeness of lit to the extensionsleeve of the fixed frame C as to hold the hand stationary when disconnected from the moving parts of the clock.
To carry out the plan of my invention, it is necessary for the third hand 0 to travel at times with and directly under the hour-hand and be carried forward with it and at other times to be left stationary to mark the time. To provide for engaging the hands together for the purpose mentioned, I provide the hourhand with a horizontal lug 0 and the third hand with a vertical lug 0 the lugs being so located that when the sleeve 0 and the third hand are moved outward to their limit the lug 0 will come in the path of the lug 0 and the hour-hand be thereby caused to carry the third hand forward with it'against the friction between the sleeve 0 and the fixed extension so long as the third hand remains at the outward end of its adjustment. The normal position of the parts is that in which the hour and third hands are engaged andtraveling together. The means for disengaging these hands, and thereby leaving the third hand stationary, consists of the plunger D, arranged to be pushed down from above the clock. The upper end of the plunger travels in a way in the frame C, and the lower end moves up and down in a way in the stud C, that extends forward from the plate 0. Between the frame C and the stud the plunger is split and expanded into a ring C 0 0 are cams extending inward from the ring and are beveled in opposite directions, so that one will operate upon one face of the cam 0 and the other upon the other face. This construction is such that when the plunger is moved down the cam c is moved inward, carrying the third hand out of engagement with the hour-hand, allowing the third hand to stop and indicate the time when the plunger was set down. As these clocks are usually used to indicate to the proprietor the time when the store is opened, to indicate such time the clerk on entering the store in the morning pushes the plunger down, thereby stopping the third hand in position to indicate the exact time. The hand remains in this position until the proprietor has had an opportunity to view it, after which he may raise the plunger to move the third hand into position to be picked up by the hour-hand when it again passes it, which will be at the time in the evening corresponding to the time in the morning when the hand was stopped. To provide, however, for automatically resetting the clock without the necessity for withdrawing the plunger by hand, I employ means for lifting the plunger sometime within the twelve hours after the clerk has set it after the proprietor has had an opportunity to note the time when the store was opened in the morning. For this purpose 1 provide the plunger with the parallel arm D. The lower end of this arm is arranged to come in contact with the cam E. This cam is attached to a gear a, which is in mesh with gear 0, mounted on the sleeve carrying the hour-han The gear a is half the size of the gear a, so that the cam E revolves once with every two revolutions of the hour-hand, or once in twenty-four hours. The cam is cut away for about half its circumference, with a direct offset at e and with a lifting-incline at 6 Thus for twelve hours the plunger, if up, can be pushed down, and at the end of the twelve hours it will be automatically lifted and cannot be again pushed down for twelve hours. The cam is set so that it will lift the plunger and throw the third hand in position to engage the hour-hand any time prior to the time when they come to gether. Thus if the usual hour for opening the store is seven in the morning the cam will be arranged to clear the plunger at, say, five a. m., and the plunger will be pushed down by the clerk on opening )the store and will remain down until live in the evening, when it will be automatically raised and the third hand be put in position to be picked up by the hour-hand again at seven in the evening.
My invention is an improvement of the construction heretofore used by which the time of opening is indicated by the stopping of the clock. In the use of such construction the use of the clock for general purposes is lost and the clock must be set each day. With my construction the clock runs continually and only the third hand is stopped,while means are provided for picking it up again during the day to be in position to be again stopped on the following morning.
It will be seen from the foregoing description of the plunger D and the cam E that the third hand is prevented from being stopped during a portion of the twenty-four hours. The object of this construction is to prevent a clerk from stopping the third hand at a time previous to the time he should operate the plunger to stop it. Were this provision not made, the clerk could stop the third hand at seven oclock in the evening, for example, and if he failed to come in at the required time, at seven oclock in the morning, the indication of the clock would not show such tardiness.
If it is desired to indicate the time at which a second clerk should arrive say at. noon or in the evening the proprietor after noting the position of the third hand can set the clock forward twelve hours in the ordinary manner by the resetting-key, when it will be ready for a clerk arriving at noon or in the evening.
It will be noted that aspring (Z is arranged to hold the plunger D by friction in any desired position. This spring is more particularly designed to hold the plunger from moving downward by its own weight, and to make it more effective for this purpose a nick or depression may be made in the plunger to receive the spring when the plunger is in its uppermost position, as shown in Fig. 4.
The cam E may also be placed directly upon the sleeve 0, thus making a revolution once in twelve hours instead of once in twenty-four hours without departing from my invention and without materially weakening the effectiveness of the device. 1 therefore claim such construction as within the scope of my invention.
