TlME-REGISTERING STAMP.

SPEGIFEGATION forming part of Letters Patent No. 445,570, dated February 3, 1891.

Application filed September 21, 1889. Serial No. 132M702. (N0 model.)

T0 to whom it may concern/.-

Be it known that I, EDWIN \V. MORTON, a citizen of the United States, and a resident of \Vhite Plains, lVestche-ster county, New York, have invented anew and usefulImprovement in 'lime-Registering Stamps, of which the following is a specification.

My invention relates to improvements in registering devices to be used in combination with a time or other mechanism and is usually applied to a time-stamp. The object of my improvement is to provide a mechanism that will record the year, month, day, hour, minute, the ante-meridian, meridian, and postmeridian, or any other matter which may be desired to record. I attain these objects by the mechanism illustrated in the accompanying drawings, in which the same numbers refer to the same parts throughout.

Figure 1 shows a side elevation of the stamp, with the hammer-holder in section and part of the casing of the stamp and time mechanism broken away. Fig. 2 shows a front elevation of stamp. Fig. is a plan view ofsaine. Fig. 1 is a side elevation of the stamp and time mechanism with one side of casing and also one side of frame of the device removed. Fig. 5 shows a front elevation of the stamp with the front of easing removed and also the ribbon-roller. Fig. (3 shows a vertical section of type-wheels and showing swinging frame in full. Fig. 7 shows a side elevation of registering mechanism. Fig. 8 is an end elevation of type-wheels, showing frameand adjacent parts in section. Fig. 9 is a side eleva tion of type-wheels and adjacent parts of registering mechanism, the frame being in section. Fig. 10 is a plan view of the stampfield. Fig. 11 is a view of stamp-impression. Fig. 12 is a side elevation of two type-wheels, showing the relative position of notches and type with adjacent parts and mechanism. Fig. 13 is a detailed view, with part of easing broken away, of the ribbon and operating mechanism therefor. Fig. 15' is a front elevation of the same. Fig. 14: shows an elevation of each of the type-wheels.

The casing of the stamp, as shown in Figs. 1, 2, and 3, is constructed of four walls and a bottom 1, 2, 3, a, and 5, united firmly together or eastin one piece. The top 6 is made of one piece and is hinged to the casing at 7, resting on the side walls of the casing 2 and 4. To this top or table is firmly fastened an arm 8. The end of this arm is provided with a sleeve, in which is fitted a reciprocating rod 9, provided at the lower end with a platen 10, usually shod with rubber, and at the other end having a knob 11. A spiral spring 12 surrounds the rod 9 and is incased within the sleeve 61, the bottom of said spring bearing upon an interior otfset at the bottom of the sleeve and a shoulder upon the rod resting upon the top of the spring. The platen will thus be maintained atits point of highest elevation.

The clock mechanism 1 usually prefer to mount in an independent frame in which the arbors have their bearings; but this frame may be dispensed with and the walls of the casing perforated to form bearings for the arbors.

By reference to Figs. 4 and 5 itwillbe seen that the time mechanism consists of the usual power-gear and an escapeinent, these two being united by a mutilated gear, which operates a crank. In this movement 13 represents the driving-spring, and 14 the arbor, to which it is attached at one end. The ratchet device by which the power is applied to the train is not shown.

15 is a gear keyed to the shaft 1-l and meshing with the lantern-pinion l6,which is keyed to the shaft 17. To said shaft is also keyed the gear 18, which meshes with the lanternpinion 19, keyed to shaft 20, to which is also keyed the gear 21, which meshes with the lantern-pinion 22, keyed to the arbor 23.

In said arbor a crank 24 is bent. Upon the arbor 23 is keyed the mutilated gear 25, the teeth of which mesh with the lantern-pinion 26 of the escapeinent-train, which is of the usual form used in clocks.

In the structure being described in this specification the time-stamp is designed to 5 register differences of one minute. It is hence necessary to move the minute-type wheel every minute. The structure, which will be hereinafter described, by which the minutewheel, together with the other type-wheels, is TOO moved is operated by the crank 24. Hence said crank must make one complete throw every minute. It will be seen that during one half of the revolution of gear 25 it is controlled by the escapement, while during the other half it moves under the direct action of the spring without control; hence instantaneously. Thus the arbor 23 must be so geared that if wheel 25 had a full set of teeth it would revolve once in two minutes; but as half of said teeth are-removed the arbor 23 and the crank 24 make one complete revolution in one minute and operate the type-wheel, as desiredthatis to say, the period during which the teeth of the mutilated gear engage the lantern-pinion of the escapement is fifty-nine and a fraction seconds, while the second half of the revolution of the arbor 23 takes place in the remaining fraction of a second.

The registering device is shown in'Figs. 6 to 11, and consists of a frame 29 or any desired support, which is usually cast in one piece. It is provided with brackets 30 30, between which is fixed a type-wheel shaft 31. On this shaft is journaled a series of wheels of an even diameter, varying in width as the type on the face thereof may require, as shown in Figs. 10 and 11. The peripheries of these wheels are faced with type of an arrangement to meet the requirements of the registry. Between the type are depressions 35 of varying depth. These operate as ratchetteeth and are engaged by the pawls of the swinging frame and stationary brake-springs on opposite sides of the wheels hereinafter described.

A rocking frame constructed as shown in Figs.6 to 9 is made in the form of a fork, the ends 37 and 37 being journaled to the shaft 31 outside of the type-Wheels. On the rear end of said fork are the brackets 44 and 44, whichproject from it and in which is journaled the rockshaft 38, to which are secured the pawls 39, 40, 41, 42,-and 43, and engaging the type-wheels, as hereinafter more fully described. Encircling the shaft 38 is a spiral spring 45, which is secured to said shaft at one end and the bracket 44 at the other, and by a torsional strain presses the pawls upon the type-wheels. To the rear end of the fork is secured a slotted arm 46, which may be made of two bars or pins, as shown in Figs. 8 and 9. The crank 24 engages the slot in said arm and moves it and the fork and pawls back and forth. The pawls '39 4O 41 42 43 are rigidly secured to the shaft 38. They are usually of'difierent lengths and are bent so as to be in difierent planes. Pawl 41, which moves the wheel indicating the units of minutes, is the lowest; 40, which moves the wheel indicating the tens of minutes, is next above the unit-pawl; 39,which moves the wheel indicating hours, is the next above the tens-ofminutes pawl; pawl 42,which,moves the typewheel indicating the postand ante meridian, is the highest pawl, and paw-1 43 drops entirely below the level of the face of the typewheels and also the otherpawls, and engages with the pins 60 on the side of a wheel indicating the meridian. be accomplished by making the pawls of different lengths as well as of different elevation.

Secured to' the frame of the registering mechanism on the side of the type-wheels opposite to that on which they are engaged by the pawls are the spring-brakes 47 47, &c. They are equalin number with the type-Wheels and bear upon the surface thereof, and engage notches in the surface of said wheels, and hold the wheels stationary. The notches with which these spring-brakes or check-stops engage are so located that the type-wheels will be held in such position in the field of the The same result may stamp as to present a perfect line of type for printing.

The construction of the registering devices as applied to a time-stamp is as'follows:v Figs.

6, 7, 8, 9, and 10 show the various views of the type-wheels. In Fig. 6 the wheels are shown in section, journaled on the shaft 31, and are numbered as follows: \Vheels 50,51, 52,53, 54, 55, 56, 57, and 49, indicate, respectively, as shown in Fig. 10, the month, the tens of the days of the month,the units of the days of the month, the hour of the day, the tens of .will be seen that pins 58 59 are passed through the shaft 31 on the outside of the wheels 53, 54, 55, and 56, thusseparating them from the adjoining wheels, so as to avoid the danger of the latter wheels being moved when the former are turned by the clock mechanism. The motion of the wheels 49, 50, 51, and 52 has been described and need not be further mentioned. Those moved by the clock mechanism will now be described. Wheel 55 is used to indicate units of minutes, and has on its surface ten type-surfaces, being numerals from 1 to9 and zero. Between the type-faces are indentations, all of which are of equal depth with the exception of that between the type-faces 2 and 3, which is deeper than the others. Wheel 54 is the next adjoining one on the left, as shown in Figs. 6 and 7, and is used to indicate tens of minutes. This wheel has twelvetype-faces on its surface and indentations between said type-faces, all of which are of equal depth with the exception of two, which are on opposite sides of the wheel. The numerals on this wheel are 1 2 3 4 5 O1 2 3 4 5 0,.and the indentations are between the figures 3 and 4 on each ICO IIS

side of the wheel. Wheel 53 is used to represent hours, and has upon its surface twelve typefaces, from 1 to 12, inclusive. Between said type-faces are indentations, allof them of equal depth except one-that between the types 3 and 4., so located in consequence of the relation between the pawls and the printing-line of the type-wheels. Vheel 56 is located on the left of wheel 55 in Fig.6, and is used to indicate the ante-meridian and postmeridian. The relative motions of these wheels will now be described. They are all moved by the pawls 39, 40, 4:1, 42, and 4-3,which are rigidly secured together, and, as above described, are so bent as to stand one below the other. The deep notches in the various typewheels above mentioned are of unequal depth in the various wheels. That in wheel 55 is the deepest, those in wheel 54 next, those in wheel 53 next, and those in wheel 56 next. The wheel 56 has on its side four pins 60,which project therefrom, and which are engaged by the downwardly-bent pawl 4-3. Vhen the pawls are operated, the pawl 41, resting upon the periphery of wheel 55 and being the lowest pawl of a series,will retain all the others in an elevated position above their various wheels and out of engagement with their several indentations, until said pawl falls into the deep notch of wheel This will cause pawl 40 to engage all indentations of the wheel 51, and as the pawls are moved will turn said wheel forward one step. If it should happen that the indentation below the pawl 40 in wheel 5%,

should be one of the deep indentations in said wheel, the pawl will sink low enough in said indentation to allow the pawl 39 to engage one of the indentations in the wheel 5-3, so that said wheel may be moved forward one step by the motion of the pawl. If it should happen that the indentation into which the pawl 39 falls is the deep indentation'of wheel 53, then pawl 42, which is the next highest one, will fall upon and engage an indentation in the wheel 56 and move said wheel forward when the pawls are moved. The indentations in the wheel 56 are so arranged in relation to the pins 60 on the side of said wheel that they will stand with three indentations in said wheel between each two pins.

Wheel 56 is provided with twelve typefaces A. M, M., and P. M., successively, in four groups. Whenever the pawl of the wheel 53 falls into the deep indentation in said wheel and permits the pawl of wheel 56 to engage its indentations and move it forward and exposes the symbol M.,then the pawl 43 will engage one of the pins 60, and the next motion of the pawls, which will take place with the next minute, will move the meridian-wheel forward and bring the symbol P. M. into the printing-field.

An examination of Fig. Dand of the foregoing description of the type-wheels will disclose the fact that several of the wheels are provided with twelve type-faces, while wheel 55 has but 10. This would cause confusion in the printing but for the arrangement hereinafter described.

The unit of minute-wheel must revolve onetenth of a revolution at each throw of the pawls, and the tens-ofminutes and hour wheels must make one-twelfth of a revolution at each throw of the pawl. The accord of these wheels is accomplished by the device shown in Fig. 12. The indentations of the wheels and 54 are made shorter than those of wheel 55, and so located that the pawls, which actuallytravel at each throw a distance sufficient to turn the wheels one-tenth of a revolution, will, when they fall into their notches, engage and begin to turn the wheel 55 before they engage the notches of the other wheels, and will then take up the other wheels and move them the remainder of the throw of the pawls, the lead of the notch in 55 being the difference between the one-twelfth section of the type-wheel and one-tenth section. It will be readily seen that this method of synchronizing the motion of the type-wheels might be employed, no matter what difference there might be between the number of types on the wheels.

The inking mechanism consists of a ribbon wound upon spools 62, journaled in brackets 63 63 of the cover 6, as shown in Fig. 13, and held in said journal by a device which will now be described.

The bracket 63 is provided with notches 6t (St on either end, into which the shafts of the reels tit. Pivoted to each of said brackets above the bottom of the notches 64: Gtare fingers 65 65, in one side of which a semicircular notch 66 is out, which fits upon and holds the shaft of the reel in the notches 64 6t.

67 is a spring bearing upon the back of the finger 65 and holding it in engagement with the shaft 66. When it is desired to insert the spools 62 62, they may be pressed into the notches 64: 64 and will be caught and held there by the fingers 65.

The periphery of one end of each spool is cut with ratchet-teeth, and a pawl 68 engages them, which is pivoted to one end of the bellcrank lever 69, which is pivoted in the cover 6 at 70, the other arm of said bell-crank lever standing, at little above the level of the printing-table, and in such position that it will be struck by the platen when it descends, and as it is moved downward will operate the ratchets and turn the spool, thus drawing off a fresh portion of ribbon. The bell-crank lever is held up to its point of highest elevation by aspring 71, secured to it and bearing against the interior of the cover. \Vhen the ribbon has been completely wound upon one reel, the reels may be removed and rematter of the field of the stamp. This shaft is provided with a knob projecting beyond the casing of the stamp, said knob being provided with faces of type thereon, indicating the character of the type or Word upon the corresponding faces of the shaft. It is also provided within the registering-frame of the stamp with the ratchets 73, engaged by a check-stop 74. On the surface of the frame of the registering device 29 is securely fastened a plate'or die 75, having words in type raised thereon and spaces in which the letters upon. the registering device and also upon the shaft 72 may stand. All the types must be arranged in the same'horizontal plane.

Referring to Fig. 9, the lantern-pinion 26 is provided with a concave depression 76 on its periphery of radius equal to the mutilated gear 25, and of such relation to the mutilated gear that when the'last tooth of the gear leaves the pinion and the half-ring which is riveted to the under side of said mutilated gear, and which has aplane surface 011 its periphery, it will come in contact with said depression and stop the motion of the pinion 26 and hold it stationary until a tooth of the mutilated gear comes in contact with said pinion. The depression 7 G is so located upon the periphery of the pinion 26 that when said depression is caught by the semicircular segment on the under side of the mutilated gear 25 and held stationary thereby while said gear is making a half -revolution the bars of said pinion will be in proper position to be engaged by the first tooth of the mutilated gear succeeding the blank space in said gear. I have not claimed in this application the bottom principle of the registering device, but only its application to a time mechanism. This principle is the subject of another application filed herewith.

What I claim, and desire to secure by Letters Patent, is
