TIME-STAMP.

To all whom it may concern.

Be it known that I, CLARANCE C. SnsLEY, a citizen of the United States, residing at Perth Amboy, Middlesex county, New Jersey, have invented certain new and useful Improvements in Time-Stamps, of which the following is a specication.

My invention has reference to stamps or devices for impressing the time of receipt etc., on paper and the like, such as the hour and minute, and the invention has for its object to provide simple and effective means for causing the hour and minute indicators to be regulated and operated by means of electric current controlled by a timepiece or clock.

My invention comprises the novel details of improvement and arrangements of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein,

Figure 1 is a perspective view of a time stamp embodying my invention. Fig. Q. is a plan view, enlarged, of the dial and t-ime pointers. Fig. 3 is a side elevation of the operating devices of the stamp removed from the casing of Fig. 1. Fig. i is a central sectional view, enlarged, of the operating devices of the stamp. Fig. 5 is a cross section substantially on line 5, 5, Fig. 4, looking in the direction of the arrows, and Fig. 6 is a detail view of the magnet and controlling wheels of the stamp.

Similar numerals of reference indicate corresponding parts in the several views.

In the drawings the numeral 1 indicates a suitable casing shown provided with a detachable cover 1a upon which is mounted a stamping pad 2 shown carried by a plunger 3, that is guided by a bracket 5, supported upon cover 1a and raised by a spring a, but it will be understood that any suitable means for controlling the stamping pad may be provided.

At 6 is a dial member carrying the numerals l to 12 to indicate the hours, which dial has a centrally disposed opening or socket (3 in which are located the hour pointer or arrow 7 and the minute pointer 8. The casting for the dial number 6 is shown received in an opening 2a in cover 1a and held to the cover by screws 9.v The minute pointer 8 is shown carried upon a flange Specification oi' Letters Patent.

Application filed January 9, 1906.

Patented Mar. 8, 1910. serial No. 295,225.

10 extending upwardly from a disk 10a fitted to rotate within the socket (ia of dial number 6, the disk 10a having a hollow shaft or stem 10b passing downwardly through a bearing or opening in the bottom of dial member 6, and by preference I interpose anti-friction balls 11 between the bottom of dial member 6 and disk 10a to permit free revolution of said disk. Within the recess 10C that is formed by the flanges 10 of disk 10a is located the disk or support 7a of the hour pointer 7, said disk having a shaft 7 passing through the bore in shaft or stem 10b so as to rotate therein, and b preference I rovide anti-friction balls 12 between the disks 7 a and 10a to permit free rotation of one with respect to the other. The arrangement of the parts is such that the upper or working surface of the numerals of the dial and of the pointers 7, 8 are substantially iiush so that when an inking ribbon 13 lies over the dial and pointers and a paper is placed upon the ribbon under pad 2 and the latter is stamped down upon the paper the impression from the dial numerals and the pointers will be printed upon the paper, and the thrust of the pad is transmitted from the pointers through the balls 11, 12 to the bottom wall of the dial member G.

The means I have shown for rotating the hour pointer 7 one revolution during 12 hours, and for rotating the minute pointer 8 one revolution during each hour are as follows :To the shaft 10 of the minute pointer disk 10L are secured ratchet-wheels lil, 15 having an equal number of teeth, as sixty teeth each, facing in opposite direc tions, as illustrated in Fig. 5. Said ratchets may be formed on a single piece of metal or in separate pieces secured together. A dog 16 carried by an arm 17 engages ratchet 14, a spring 1S carried by arm 17 holding dog 16 against the ratchet, arm 17 being secured to a shaft 19 that is journaled in a frame 20 shown secured to and depending from the lower part of dial member 6. 21 indicates a spring-acting back-stop dog shown carried by frame 2O and acting with rachet 14E to prevent reverse movement of the latter. In order to prevent ratchet 14: from overrunning the proper distance that it is moved by dog 16 at each minute stroke, I provide a dog or iinger 22 carried by arm 17 and adapted to engage the teeth of ratchet 15, the relation ot said doe' Q2 to the teeth ot' ratchet 15 being such that as arm 17 causes dog 16 to move ratchet 'iet the distance ot a tooth the dog 22 will encounter a tooth ot ratchet 15 and thus prevent the ratchet 14; from being pushed too tar beyond the proper distance tor each step or movement of the pointer S for the minutes to be indicated. Thus, as arm 17 is rocked the minute indicator 8 will be moved one st-ep equal to aminute on the dial for each toi-ward movement oit dog 1G. The means I have shown tor oscillating arm 1 7 one step for each minute ot time comprises a magnet 2 3, whose armature 24k is secured to shaft 19, a spring connected at one end with said shaft and at the other end with frame 20, as by a screw 26, acting against the action of the magnet in well known manner. The terminals 26, 27 of the magnet are shown connected with binding posts 2S, 29 on trame E20, from which line Wires 30, 31 lead, as through a hole inbox 1,to a make-and-break device of any suitable kind controlled by a timepiece (not shown) in well known manner. As shown in F 1, the wires 30, 31 connect with contact-springs 32, a iinger 34tcarried by an arbor 35 rotated by the timepiece causing said contact springs to make and break the circuit, a suitable battery (not shown), being provided tor the circuit. In the arrangements shown it is designed that linger 34 be rotated once for each minute to make and break the circuit each minute of time.

In order to cause the hour pointer 7 to rotate once during twelve hours of time, or 1/12 as tast as the minute pointer 8, I provide the following arrangement 1-To the shaft 7b ot the hour disk 7 is secured a gear 37 that meshes with a gear 3S which is secured to or made integral with a gear 39, gears 3S and 39 being mounted to rotate on a shaft or screw 40 that is shown carried by ratchet 15, and gear 39-meshes with a gear it1 that is held from rotation, as by being` secured to trame 20, whereby as ratchets 14 and 15 are rotated the gears 38 and 39 will be carried bodily around gears 37 and 41. The ratio ot this gearing is such that it'or each revolution ot ratchets 14 and 15 around the axis ot shaft 7b, the hour pointer 7 will be driven 'forwardly 1/12 of a revolution while the minute pointer S makes one complete revolution. The ratio of gears 37, 3S, 39 and i t1 to produce theabove named results' may be as tollowst-gear 37 to have twenty-tour teeth, gear 38 to have twenty-two teeth, gear 39 to have twenty-four teeth and gear t1 to have 22 teeth; and thus as gears 3S and 39 are carried bodily around gear 39 and roll on the stationary gear 41, they will cause gear 37 to rotate, and by reason of the ratio ot .said gearing 37 will be advanced only 1/12 of a revolution tor each complete revolution oit gears 38, 39 bodily around gear stl. In accordance with the arrangements described the gearing etc., may hang suspended from cover 1fL within casing 1 when the cover is secured thereon, and as finger 3a closes the circuit of the magnet once each minute the armature 34- will oseillate shaft 19 and cause dog 1C to operate the ratchets and thereby move thc minute pointer 8 one step forward each minute, and the gearing 37, 3S, 39 and a1 will cause the hour pointer 7 to move torward 1/12 as 'tast as the minute pointer S, and thus when an impression is made upon the paper the minute and the traction ot the hour will be indicated by the respective pointers.

I have shown a single time stamp electrically connected with a make-and-break device to be controlled by a timepiece, but it will be understood that while a single timepiece may be used to control a single time stamp, a plurality ot time stamps can be connected with a single or master clock by arranging the circuit in any well known manner, so that all the time stamps so connected with the timepiece will have their respective minute and hour pointers adj usted synchronously as the minutes pass.

My invention is not limited to the particular deta-ils ot construction shown and described as they may be varied withoutdeparting from the spirit thereof.

Having now described my invention what I claim is 1. A time stamp comprising a dial member having a socket, a minute indicator disk journaled therein, a plate having an opening receiving said member, an arm carried by said plate and extending over said member, a pad carried by said arm over said member, antifriction balls between the dial member and said disk, the minute indicator disk having a recess, an hour indicator disk within said recess, anti-friction balls between the minute and hour indicator disks, a wheel connected with the minute indicator vdisk and suspended below said dial. member, means to impart step-bystep movement to said wheel, a gear connected with the hour indicator disk below said wheel, a` stationary gear below the First named gear, a pair of united and pivotally carried by said wheel and meshing with the `in .licator gear and with the stationary gear.
