SPECIFICATION forming part of Letters Patent No. 413,328, dated October 22, 1889.

Application filed November 15, 1888. Serial No. 290,892, (No model.)

To @ZZ whom it may concern:

Be it known that l, EBENEZER H. ROGERS, J r., ot' New York, in the county and State ot' New York, have invented a new and useful Improvement in Time-Stamps, of which the following is a specification.

l Will describe in detail a Lime-stamp embodying my improvement, and then point out the novel features in claims.

n the accompanying drawings, Figure l is a vertical section taken on the plane of the line a" .1, Fig. Fig. 2 is a vertical section taken at right angles to Fig. 1 and on the line 1/ y, Fig. l, and looking in the direction of the arrow in Fig. l. Fig. 3 is a plan or top view of the same, the surrounding case and the hand-stamp being removed. Fig. 4@ is a side view of the time mechanism of the stamp, looking in the direction of the arrow of Fig.

Fig. 5 is a rear view of the time mechanism for the stamp, the case being removed. Figs. G, 7, S, 9, l0, and 1l are detail views of the time mechanism of the stamp.

Similar letters of reference designate corresponding parts in all the iigures.

My improvement involves the use of clock mechanism, which may be of any desirable kind, which clock mechanism transmits motion to a series ot' indicating-Wheels, whereby time may be recorded upon a paper or document when the same is forced against the indicator-wheels. rlhe time indicated will be that of the year, the month,the day, thehonr, the minute, and Whether the impression is made during a.m. or p. m., the shortest duration of time indicated being that of minutes. Motion to operate the minute-indicating Wheel is transmitted direct-ly from the minute-shaft.

Referring more particularly to Figs. 2, 3, and 4, A designates a pinion driven from the pinion A on the minute-shaft of the clock. These pinions are of the same diameter and have the same number of teeth; consequently the pinion A Will rota-te at the same speed as the minute-shaft of the clock. rlhe pinion A is mounted upon a shaft o., journaled in suitable bearings in the main frame B of the time-indicating mechanism for the stamp. Upon the shaft a is mounted a ratchet-Wheel A2, .which ratchet-Wheel. has sixtyteeth. Rigidly mounted upon a rock-shat' t Ajn, Which latter is also journaled in the main frame B, is a lever A4. The lever A4 hears near its lower extremity a tooth of. (Shown more clearly in Fig. 9.) The tooth a is in contact with the teeth upon the ratchet-Wheel A2. The ratchet-Wheel A2 rotates in the direction of the arrow shown thereon in Fig. 9; consequently as it`rotates the tooth a willbe moved outwardly by the teeth upon the ratchet- Wheel successively, causing the lever A4 to rock, and causing the rocking ot' the rock-shaft A3. Upon the outer end of the rock-shaft A3 is a fingere?, rigidly secured thereon. Against this iinger bears a spring o3, which springis secured near its lower end in a suitable support me de fast to the frame B. rlhe tendency of this spring is to always cause the rocking of the rock-shaft A3 in such manner that the tooth a of the lever A'L Will be maintained irmly in contact with the teeth of the ratchet-Wheel A2. rocked by the rotation of the Wheel A2 and the tooth a moves past one of the teeth on the ratchet-Wheel, it Will be quickly sprung into the adjacent space between the tooth just passed and the next tooth. rlhe upper arm of the lever A1 bears near its extremity a pawl of". rlhis paWl is loosely hung upon the lever. Its outer extremity bears a tooth a, which tooth engages with the teeth upon a ratchet-Wheel A5. rlhis ratchet-Wheel is rigidly secured upon one side of a minute indicator-Wheel A6. The minute indicator-Wheel bears upon its periphery raised iigures, extending successively about the periphery, and indicating the minutes from one to sixty. A complete rotation of the minute indicatorwheel occurs each hour. XVhe-n the ratchetwheel A2 rotates to cause the rocking of the lever Ail, the paWl a5 Will be moved along a distance equivalent to the length of a tooth upon the ratchet-Wheel A5, and when the tooth c' on the lever A4 springs into the next notch on the Wheel A2, through the action ot the spring as, the pau-l a5 will be moved rearwardly, so that the tooth a thereon will cause the rotation of the ratchet-Wheel A5 a distance equivalent to the length of one of the teeth thereon. As there are sixty teeth on the vvheel A5, and there are sixty impulses given to theleverAL 'Vhen, therefore, the lever A4 has been Araised figures indicating twelve hours.

bythe wheel A2, there will be sixty impulses given to the wheel A5 and' to the minute in. dicator-wheel A6.

A7 indicates a stop-pawl mounted upon a rock-shaft 0.7, journaled in the frame B. Outside the frame said rock-shaft has rigidly secured to it a finger a8, actuated by aspring a9 in a manner similar to the spring a2.v This spring operates to keep a toe al@ upon the stop-pawl A7 in constant contact with the teeth of the ratchet-wheel A5. lThe stop-pawl prevents the reverse rotation of the wheel A5 from the direction'i'n which it was rotated by the pawl a5.

Upon the shaft a is rigidly'mounted acam b. As shown, this cam is what is known as a snail-cam. Against the periphery of this cam bears atooth b upon one arm of a lever B. (Shown more clearly in Fig. 8.) The lever B is rigidly mounted upon a rock-shaft b2, journaled in the frame B. Its upper arm has pivotally connected with it a pawl b2, provided with a tooth b4. The tooth b4 engages teeth upon a ratchet-wheel B2, rigidly secured to one side of an hour indicator-wheel B3. The hour indicator-Wheel B3 has upon its periphery The ratchet-wheel B2 has twelve teeth. As the shaft a rotates but once each hour, the snail-cam b will consequently be rotated but once in the same period. As the tooth b of the lever B bears against the periphery of the cam b, the lever will'be gradually rocked during the rotation of the cam unt-il it has moved the pawl b3 and the tooth b4 thereon a distance equivalent to the length of one of the teeth on the ratchet- Wheel B2. At each complete rotation of the cam b the tooth b on the lever B will-move over the step upon the cam by reason of the action of the spring b5- operating upon a iinger h6, lmounted on a rock-shaft b2, and acting in the manner previously described for` the springs a3 a9. When so rocked, the pawl b2 will be retracted, causing the tooth b4 to rotate the ratchet-wheel B2 a distance equivalent to the i length of one of the teeth thereon, Vthus rotating the hour-wheel adistance equivalent to the distance between two of the raised figures upon its periphery.. As the cam b rotates but once each hour, an impulse will be given to the hour-indicator wheel but once yeach hour.

(3o-operating with the ratchet-Wheel B2 is a stop-pawl B4, actuated by a spring 57, operating upon an arm bs, rigidly secured upon a 'rock-shaft b9 in the manner previously described.

' `I will now describe the manner in which the days of the'month are indicated and also the divisions of each day into a. 1n. and p. m. Upon the minute-shaft Sof the clock, outside the pinion A', isa pinion C. The pinion C gears with a pinion C', mounted upon a stud c extending from the frame of the clock. Upon the stud c, outside the pinion C', is a pinion C2, which pinion gears with a pinion Cwhich pinion is rigidly mounted upon a shaft C4, journaled in the frame B. Upon the shaft C4 are rigidly secured two cams C5 C, which rotate with the same. The pinions C, C', C2, and CS are of such diameter that they cause the rotation of the shaft C4 once in every twenty-four hours. The cam C5 is a snail-cam. Against its periphery bears a tooth c upon the lower arm of a Alever C7, mounted upon a rock-shaft C8, journaled in suitable bearings in the frame B. This lever `is s ring-actuated in one directionb a s rino' b b c2, acting upon an arm c2, rigidly secured upon the rock-shaft C8, outside the frame B in the manner previously described. The upper arm of the lever C7 has pivotally connected toit a pawl C9, which pawl is provided with a tooth c4, which pawl engages the teeth upon a ratchet-wheel C10, which ratchet-wheel is rigidly secured to one side of a day-indicator wheel C11, the periphery of which has formed upon it raised figures indicating the days of the month. The ratchet-Wheel C10 is provided with thirty-one teeth. Each time the snail-cam C5 rotates it causes the gradual rocking of the lever C7, and causes the movement of the tooth c4 upon the pawl C9 a distance equivalent to the length of one of the teeth upon the ratchet-wheel C10, and each time the tooth c on the lever C7 moves 0E from the step upon the cam the pawl C2 is retracted by the spring c2, causing the rotation of the ratchet-wheel C10 a distance equivalent to the length of one of the teeth on said wheel. As there are thirty-one such teeth, thirty-one impulses will be given to said wheel and to the day-indicator wheel each month. If there are less days in the month than thirty-one, the lever C7 may be rocked independently ot the cam C5, to set the day indicator-wheel. This is accomplished by a pin la, secured to the lever C7 and extending through a curved slot k to the outside of the case K.

It is desirable to indicate the division of the day into a. m. and p. m. For this purpose I arrange upon the shaft C4 an S-cam, bearing against the periphery of which is a tooth d upon a lever D, mounted upon a rock-shaft D journaled in the frame B. The leverD is spring-actuated by a spring d', operating upon a finger d2 upon the shaft D', outside the frame B, and adapted tohold the leverD in contact with the cam C6 in the manner previously described. The upper arm of the leverD bears a pawl D2, provided with a tooth d3 engaging the teeth upon a ratchet-wheel D3, rigidly secured to one side of an a. m. and p. m. indi-4 cator-wheel D4.

The indicator-Wheel D4y is provided upon its periphery with the letters A. M. and P. M. I have shown twelve such combinations of letters and twelve teeth upon the ratchet-wheel D3; but I may use any desired number. 'Each time the -S-cam is rotated it twice rocks the lever D at regular intervals (or, in other words, once every twelve hours) in such manner that the pawl D2 will be moved inwardly upon the ratchet-wheel D3 a distance equivalent to the length of one of IOO IIO

said teeth, and each timethe tooth d is moved off from a step upon the cam Cthe lever will be retracted by the spring a', to cause the rotation ot' the wheel D3 a distance equivalent to the length'of one of its teeth, thus giving an impulse to the wheel D"L once every twelve hours.

Co-operating with the ratchet-wheels Cw D3 are stop-pawls D5 D, mounted upon shafts D7 DS, and actuated by springs D9 D10, bearing against fingers D11 D12, rigidly mounted on the shaft DT DS. Coacting with each of these levers A4, I3', C and D are springs e. These springs are shown as Hat, and secured near one of their ends to the said levers, respectively. At their free ends they hear against squared ends of the pawls a5, h3, C, and D2, and serve to maintain such portions in engagement with the teeth upon the ratchetwheels A, B2, CW, and D3, respectively. Cooperating with the pawls ci, bis, C9, and D2 are stops f, which stops consist of pins extending inwardly from the side portions of the frame B and into the path of toes upon the pawls. These stops prevent the pawls from being' moved too far in one direction bythe respective springs a, h, c2, and d.

In Fig. 6 I have shown an indicator-wheel G, for indicating the months of the year. Upon the periphery of this wheel are raised letters indicating the twelve months. Upon the wheel G is rigidly secured a toothed wheel G. Secured upon the frame B is a support g for a spring' g. The spring' g bears upon a stop-pawl g2, which stop-pawl is adapted to engage the teeth of the toothed wheel G. Extending to the outside of the frame B is a shaft g3. Upon the inner end of said shaft is rigidly secured a toe g". The toe gtis in contact with the teeth upon the toothed wheel G. Then the shaft is rotated, the toe g4 will cause the rotation of the toothed wheel G a distance equivalent to the distance be tween two teeth on said wheel, and consequently the rotation of the wheel G a distance equivalent to the distance between any two adjacent months indicated upon the wheel G. I have shown a coilspring g5, abutting at one end against the wheel G and at the other against a collar gt, whereby the toe g'l is maintained in engagement with the wheel G.

In Fig. ll I have shown an indicator-wheel for years. Upon this wheel any number of years may be indicated in raised letters. This wheel may be rotated by hand by placing the finger upon the raised figures indicating years upon the periphery of the wheel and moving it circumferentially. In combination with this wheel, which I designate by the letter H, I have shown a toothed wheel H and a stoppawl 7L', actuated by a spring la?.

All the wheels A, 3, C11, D, G, and H are mounted upon a single shaft, which shaft passes loosely through them, so that they may be rotated freely thereon. The shaft G11 is rigidly secured near its ends in the side portions of the frame B.

In Fig. 3 I have shown more clearly a means for indicating the sort of record the time of filing ofwhich it is desired to record. This record consists of an octagonal or many-sided barrel J, mounted upon a shaft journaled in the side portions of the frame I3. Upon the outer end of this indicator-barrel is secured a hand-piecejz, by which the shaft and the barrel .I may be rotated. I prefer that the said hand-wheel be as many-sided as the barrel, and that upon each side of the handpiece should be delineated a record agreeing with that upon the corresponding side of the barrel when both are uppermost or in a position to be printed upon. Upon the upper side of the printed mechanism and opposite the indicator last described may be arranged the name of a person, lir'm, or office, as the case may be, for whom the record is being made. This indicator I have designated by the letter J2, and the same may be -stationary and cast in a top plate J 3 for the indicator. Upon each side of the top plate J i" are arranged rollers over which may be passed an ink-ribbon. A case I( contains in this example of my improvement both the clock mechanism and the time -indicator mechanism. Upon the top of the case K and rigidly secured thereto is an arm KX, which arm bears near one end an upright tubular portion, through which extends a tube 7c', upon the upper end of which is a hand-piece 7a2. lVithin the tubular portion 7.1 is arranged a coil spring k3. Upon the lower end of the tubular portion is arranged animpressionplate r. The spring abuts upon one end against the handpiece 7g2, and vat the other end against a screw 7e, passing through the tubular portion of the arm and the tube 7e. By depressing the hand-piece k2 the impression plate L may be pressed downwardly upon the top of the figures or letters appearing upon the indicator-wheels and the coilspring 7113 and above the hiking-ribbon which may be employed. If now paper or other document be placed between the impressionplate 7e* and the indicators appearing at the top of the indicating mechanism and the hand-piece 7a2 be depressed, the time at which the impression was made will be accurately imprinted upon said paper or document. As the indicator-wheels for the minutes, hours, days, &c.,.are all of the same diameter, the time which it is desired to indicate will be accurately presented at the same time, just above the surface of the plate J3, in order to accomplish the imprint referred to.

In order to accomplish the setting of the clock and the time-indicator mechanism at one and the same time, I have shown a shaft L, protruding near one end beyond the case K, which shaft is journaled in the side portions of the frame B. Upon the inner end of this shaft is rigidly mounted a pinion Z, which pinion is adapted to engage the pinion A upon the minute-hand shaft of the clock. This pinion Z is not, however, always in en- IOO IIC

gagement with the pinion A. I desire to keep it normally out of such engagement, and for this purpose I employ a coil-spring l', abutting at one end against one of the side portions of the' frame B and at the other against a collar l2, rigidly secured to the shaft L. The tendency of this spring is to force the pinion Z out of engagement with the pinion A. By forcing the shaft L inwardly, however, against the resistance of the spring Z the pinion Z will be caused to engage the pinion A', when, by rotating the shaft L, the pinion A may be rotated in such-.manner as to set the clock properly. As the pinion A controls the time-indicator mechanism, by rotating the said pinion the time mechanismor, in other words, the indicator-wheels operated by the clock-is set at the same time as the clock. l

WVhat I claim as my invention, and desire to secure by Letters Patent, is-
