To all whom it may concern/.-

Be it known that I, FREDERICK Il'. Srrronns, a citizen of the United States, and a resident of New York,in the county of New York and functions of it, and being a very simple and effective controlling device for the disk-shifting power, all as hereinafter fully described, reference being made to the accompanying drawings, in which- Figure 1 is a side elevation of myimproved time-stamp with the plate of the case removed and part of the rim of the case inclosing the hands and the dial broken out. Fig. 2 is an elevation of the reverse side, also with the plate of the case removed, also with a part broken out same as in Fig. 1. Fig. 3 'is a transverse section on line 3/ y, Fig. 1. Fig. 4: is a top view with the impression-arm and part of the top plate removed. Fig. 5 is an elevation of the stamp power releasing and stopping device, as seen in the direction of arrow (1, Fig. 1, the case and impression-arm being sectioned on line no it. Fig. 6 is an elevation of the clock attachment for controlling the releasing and stopping device, as seen in the direction of arrow 1), Fig. l, the case being sectioned same as in Fig. 5. Fig. 7 is a section of the type-disks in the plane of the shaft.

In the front upper portion of the shortcase a, only long enough for the arm I) of shortest practicable length for carrying the impression-plate c, I arrange the system of typedisks, as the minute-disk (l, hour-disk 0, meridian-disk f, day-disk g, month-disk 71., and the year-disk i, with a spring-power device directly under these disks for driving them, a clock in the back part of the case for controlling the periods of the disk movements, and the trip and stop devices for the disk power in the space between the disks and the spring-power driver and the clock.

For the power device for operating the disks I employ an ordinaryclock motion or similar motor apparatus, whereof j indicates the spring-barrel, from which the power is transmitted by the toothed rim 7; to the usual train of multiplying gears, in which train I apply the cam-disk l on the shaft 411, which corresponds to the minute-hand-carrying shaft of the clock. This cam-disk actuates the typedisks through the pawl-lever n and pawl and has thirty cam projections 19 for shifting said disks every two minutes, said disk making one revolution per hour. These projections raise the lever and pawl to engage one notch of the ratchet g on the minute-disk (I, and the spring 8 thrusts them down and shifts the disk when the cam projections escape from the tappet t on the lever.

The disk d turns loosely on the shaft u and has a cam 1;, which at each revolution of said disk sets and releases pawl-lever w, which,by its pawls c and 11 shifts the hour-disk e and the meridian-disk), which have ratchets 2, on which said pawls take effect to shift them both alike, it being preferred to have the characters of the meridian-disk repeated and to shift it each hour in unison with the hourdisk, so that it may be shifted by the same pawl-lever that shifts the hour-disk rather than provide the extra cam and pawl-lever that would otherwise have to be provided for shifting it twice each day. The hour-disk c has a similar cam P, which at one revolution of said disk sets and releases pawl-lever 2, which by its pawl 1c shifts the day-disk g through a similar ratchet .2". Said pawl-lever and pawl-lever '20 also are thrown by their respective springs 3 when released by the cams by which they are set. preferred to omit the cams, levers, pawls, and springs for actuating the month and year disks 72 and weaving them to be set by hand; but they may be provided with these requisites for automatic action,if desired. All the disks will have spring or equivalent stops, as 28, or some equivalent thereof, to hold them at rest,but releasing them by the force of the shifting-pawls.

In another position in the multiplying train of the spring-power I provide the shaft 4, timed to make half a revolution to the movement of wheel 1 the length of one cam projection 1) and carrying a crank-pin 5, which is connected by the rod (5 with the tilting tube In this case I have 7, pivoted at 8, which is the middle of its length, the arrangement being such that the throw of the crank will vibrate the tube from one to the other of the inclined positions of it represented in Figs. 1,2,3, and 5. At each end of this tube, when in the lowest position, is a spring-catch 9, which catches and holds the tube when it comes to that position, and thereby stops and holds the spring-power train against further movement u ntil the tube 1s released from the spring-catch. For so releasing it the nose 10 of the catch extends up ward across the bore of the tube so as to be exposed to the impact of a ball 11, which is carried in the tube and which, being released at the proper time from the position where it 1s retained at themiddle of the tube until allowed to fall, strikes the nose of the catch and forces it back so as to release the end of the tube and then permit the power-train to move another stage and bring down the ether end of the tube, which is then caught and held by the other catch. The tube has lips 12 proecting inwardly at the ends to prevent the escape of the ball without interfering with the action of the catches on the tube or of the ball on them. When the tube is so released, the ball is carried upward with the rising end of said tube, and when reaching an altitude above the level of the pivot of the tube the ball rolls downward along said tube until arrested at the middle by the finger 13 reaching into the tube through the slot 14 in its upper side. This finger swings from the pivot 15 at a suitable position over the center of the tube, and has an arm 16, which, with the duplex crown-wheel 17, which I apply to the clock, is the means of controlling the periodicity of the balls action. This crownwheel is geared by the spur-wheels 1S and 19 with the axis 20, usually carrying the minutehand of the clock, and preferably for the same rateof speed; but it may vary in certain proportions either faster or slower-as, for instance, half the speed. It is made with two slde flanges 21 and 22, placed a suitable distance apart for a channel-way in which the end of the arm 16 may rest while the flanges rotate past the said arm, one on each side. These flanges are notched radially and intermediately, respectively, as at 23, suitably for the arm 16 to swing through the notches and at such distance apart that said arm will escape through them alternately at intervals of two minutes when it is desired that the type disks shall be shifted at such intervals of time. hen in the course of the rotation of the crown-wheel a notch 23 comes into the relation with arm 16, permitting it to swing through the notch, the ball resting against the stop-finger in the upper side of the tube escapes by swinging the stop-finger away by its gravitating power and runs down to detach the catch then holding the tube, and thus permit another shift of the stamp-disk-driving power. Immediately after the ball escapes from the stop-finger said finger gravitates back to its normal position, the arm 16 swinging back through the same notch out of which it escaped for the release of the ball and coming to rest against the oppositc flange for holding the stop-finger to catch the ball on its return and hold it another period of time, and release itfor the reverse movement of the ball by escaping the reverse way through said opposite flange when its notch comes to the arm. Thus it will be seen that I provide a stop and trip device for the disk-power controlled by the clock without subjecting the clock to such amount of friction as will have any appreciable eifect of interference with the time-keeping qualities of it, the only friction being what is due to the pressure of the arm 16 against the side of a flange of the erown-wheel by the pressure of the ball against the stop-flnger, said crownwheel being turned by the minute-hand shaft of the clock.

The radius of the crown-wheel may be reduced if the notches be placed closer together, or its speed may be reduced, say, onehalf, if the notches be doubled, both of which modifications would still further diminish the friction. If it is preferred to have the stamp shift at intervals of one minute, the notches in the crown-wheel will be doubled. As it is not practicable in this arrangement of the clock in the back of the case to utilize the dial 2t and the hands 25 and 26 in their usual relation to the clock, as at the axis 20, because they would be at the back of the case, where they would not be available to the user of the machine at the front, I arrange them with the power device instead of the clock, and in the corresponding axis on thereof, where they have substantially the same functions, except that the hands shift synchronously with the periodical movements of the stamp-disks instead of moving continuously with the clock.

I claim as my invention 1. In a time-stamp, the combination, with the rotating type-disks, of the spring-power driver connected therewith for moving the said disks, stop and releasing mechanism connected with said spring-power driver and controlling the movements of the same periodically, and a clock connected with and controlling the movements of the stop and re leasing mechanism, said spring-power driver and clock being independent power mechanisms, substantially as described.

clock controlling said stop and releasing mechanism, the time-indicating hands connected with the said hand-carrying shafts of the stamp-disk-driving power, and the dial, said spring-power driver and clock being independent power mechanism suitably arranged therewith, substantially as described.

7.
