UNITED STATES PATENT OFFICE JOHN SIGWALT, JR, OF CHICAGO, ILLINOIS.
IMPROVEMENT IN HAND-STAMPS.
Specification forming part of Letters Patent No. 1 73,353, dated February 8, 1876; application filed August 23, 1875.
side of the base with the covering-plate re moved, so as to show the operative mechanism contained therein. Fig. 3 is a vertical section upon line 00 w of Fig. 2, the type being raised to position for printing. Fig. 4 is a like view of the same with said type depressed, so as to permit of the rotation of the type-wheel. Fig.
5 is a partial plan View of the base and its mechanism, showing. the pawl employed for operating the dating type-wheel when in its normal position. Fig. 6 is a like view of the same, showing said pawl in engagement with said type-wheel. Fig. 7 is a plan view of the lower side of the mechanism employed for operating the month-wheel. Fig. 8 is a like view of the central portion of the casing, shdwing the means employed for holding in place the ribbon-plate and Fig. 9 is a vertical section of the same.
Letters of like name and kind refer to like parts in each of the figures.
The design of my invention is to render practicable the employment of separate type .in a dating-stamp, and-it consists, principally,
in a type-wheel arranged to rotate in a horizontal plane, and provided within its periphery with vertical recesses for the reception of type, in combination with mechanism for intermittently rotating the same, substantially as and for the purpose hereinafter shown.
It consists, further, in the means employed for giving to the type-wheel an intermittent rotary motion in one direction, substantially as and for the purpose hereinafter set forth.
, It consists, further, in the means employed for releasing the operating pawl from engagement with the type-wheel, when it is desired to revolve the latter in a backward direction,
substantially as is hereinafter shown and described.
It consists, further, in the means employed for raising the type to position for printing and for returning the same to place again, substantially as and for the purpose hereinafter specified.
It consists, further, in the means employed for arresting the forward motion of the typewheel, substantially as and for the purpose hereinafter shown.
It consists, further, in the means employed for securing the ribbon-saddle and die in position upon the base, substantially as and for the purpose hereinafter set forth.
In the annexed drawings, A represents the base-plate of my stamp, which has the general form in plan view, shown in Fig. 2, and in rear of its longitudinal center is provided with a vertical opening, a, that receives and contains a stud, b, which extends downward from the center of a rounddisk, B, said disk being thus arranged to revolve freely in a horizontal plane. A second but smaller disk, 0, pro vided in like manner upon its lower side with an axial stud, c, is pivoted upon the forward portion of the base A, its periphery being nearly in contact with the periphery of the disk B. Within the periphery of the larger disk B is provided thirty-one vertical recesses 11 and b, which have parallel sides, and extend from the lower to the upper side of the same, and each contains a type, D, that, upon its upper end has characters representing the numeral of one of the days of the month. The smaller disk 0 is provided with twelve similar recesses, c and c, for the reception of type E, which contain each the name or abbreviation of one of the months. Resting within a suitable channel that extends through the center at the upper side longitudinally of the base A is a bar, E, which is capable of longitudinal motion therein, within certain limits, and is provided upon its upper side with a boss, f, that, at its inner end, corresponds in transverse dimensions with the like feature of one of the recesses b, and at its outer end has, substantially, the width of one of the recesses c of the smaller disk O. From its inner end rearward for a'short distance, said boss inclines from the surface of said bar F upward and with said disk.
outward at an angle-of about forty-five degrees, as seen in Figs. 3 and 4.
When the bar F is moved outward to its farthest limit its boss f is contained within a circular recess, 0, that is formed within the lower side of the disk 0, as seen in Fig. 4, and ofl'ers no obstruction to the rotation of the latter and the disk B; but when moved forward to the position shown by Fig. 3, said boss passes into one recess, 0 and b, in each disk, and not only raises the type D and E contained therein, but also looks said disks in place. The disk B is caused to rotate sufliciently at each double motion of the bar F to bring each recess 1) alternately in a line with the boss f by means of the following described mechanism: The lower side of the disk Bis provided with a recess, 1), similar to that of the disk 0. and the recesses b and b are cut inward at their lower ends into said recess b. Upon the base A, at one side of its center, is pivoted one end of a bar, G, which from thence extends across nearly to the opposite side of the recess 1) of the disk B, the central portion of said bar being provided with an opening, g, which spans the axial bearing?) of said disk, and has such dimensions as to enable the free end of said bar to move a distance about equal to that of two of the recesses 1). Within the outer end of the bar G is pivoted a spring-latch, g, which, as seen in Figs. 5 and 6, is arranged at nearly a right angle to theline of said bar, has its free end toward the front end of the base A, and is capable of being pressed entirely within the end of said bar. The spring latch or pawl g engages with one of the recesses b of the disk B, and rotates the latter whenever the bar or lever G is moved forward; but when the latter is moved rearward said latch is pressed inward, and passes from one of said recesses to another without'engagement. The; bar or pawl G is operated by means of two pins, f and f, which are secured within and extend upward from the upper side of the bar F, and just before thelatter reaches the limit,
. in either direction of its stroke, engage with said pawl and move it in the same direction. When it is desired to rotate the disk B in a forward direction, the spring-latch y will trip as each recess passes over its end, and therefore offers no resistance to such movement of said disk; but against the rearward movement of the latter said latch would offer an eflectual resistance were it.not for a stud, H, which extends upward from the base A at such a point as to engage with the outer inclined edge of said latch and press it inward whenever the pawl G is moved to the rearward limit of its stroke, such operation withdrawin g the said latch g entirely from engagement When the operating-bar F .is at the rearward limit of its motion, the boss f engages with one of the recesses b of the disk B, and prevents rotation of the latter, but, in consequence of the position of the pins f and f,'said bar can be moved outward until said boss is entirely withdrawn from said recess before the pawl G is moved or its latch 9 released from engagement with the depressing-stud H. In order that the forward motion of the disk B may be arrested when it vhas moved one portion of a revolution, a stop, f, is provided upon the upper side of the operating-bar F in such position as to engage with the rear side of one of the recesses b at the instant said disk reaches position. The monthdisk 0 is caused to move forward one-twelfth part of a revolution at each complete revolution of the large disk B by means of an arm,
I, that is secured to or upon the lower end of the stud b, and engages with a toothed wheel, K, which is attached to the lower end of the axial stud c of said disk 0, said wheel K being provided with teeth k, which correspond in number with the recesses c of said disk.
A spring-detent, L, is secured upon the base A, and, engaging with the toothed periphery of the wheel K, prevents the latter from moving except when engaged by the arm I.
The mechanism described is inclosed by means of a casing, M, within which is provided a suitable opening, m, for the upward passage of the type E. A year-type, E, rests upon and is" supported by the upper surface of the disk B, just inside of the line of the recesses b, and does not change position.
Within the upper side of the casing M is provided a transverse recess, m, which has such depth and horizontal dimensions as to enable it to receive and contain a plate, N.'
at its rear end engages with the front edge of said plate. A spring, 0, beneath said slide, causes the latter to remain in engagement with said plate, except when purposely withdrawn for the purpose of removing the latter.
A ribbon is arranged within suitable boxes N and N, that are attached to the ends of the plate N, and passes beneath the same and over a die-plate, P, that is placed upon the bottom of the recess m, said die-plate being secured in place horizontally by means of two dowel-pins, p and 1;. To the rear end of the base A is hinged an arm, Q, which, when in position, extends upward and forward in a curve, and furnishes a bearing for a vertically moving spring-platen, R,of usual construction.
The object sought by hinging the arm Q is to enable it to be moved out of the way when it is desired to adjust the die-plate, renew the ribbon, Ste.
The upper side of each type-disk is provided with a series of characters which correspond to the numbers or names of the type contained within its recesses, and suitable openings m and m are provided within the casin g M, through which said characters may be seen, the latter being so arranged with relation to said type as that the numeral or name presented at each opening shall coincide with the type presented for use.
The device is' now complete. and is used in the ordinary manner, the operating-lever being drawn outward and returned to place for each change of date, while the months are changed automatically. The year-type are placed in position and removed therefrom by hand.
Having thus fully set forth the nature and merits of my invention, what I claim as new 1s-- 1. In a hand-stamp, a type-wheel arranged to rotate in a horizontal plane, and provided within its periphery with vertical recesses for the reception of type, in combination with mechanism for intermittently rotating the same, substantially as and for the purpose shown.
2. In combination with the type-wheel B, provided with the recesses b and b, and pivoted upon the base A, the longitudinally-reciprocating bar F, provided with the pins f and f, and the pivoted lever G, having within its outer end the spring-latch g, substantially as and for the purpose set forth.
3. In combination with the lever Gr, provided with the spring-latch g, and pivoted upon the base A, the stud H, secured within and extending upward from said base, and
arranged to engage with said latch whensaid lever is moved to the rear limit of its stroke, substantially as and for the purpose shown and described.
4. In combination with the type E, contained within the vertical recess b of the wheel or disk B, the longitudinallyreciprocating bar F, provided with the inclined boss f, which passes into said recess and beneath said type as said bar is moved, substantially as and for the purpose specified.
5. In combination with the rotating disk B, provided with the recesses 11 and b, and with the longitudinally-reciprocating bar F and lever or pawl G g, the stop f, secured to or upon said bar, and arranged to engage with said disk at the instant the same reaches the limit of each intermittent movement, substantially as and for the purpose shown.
6. In combination with the ribbon-saddle N, resting within the dovetailed recess m of the casing M, the spring-slide 0, arranged to move longitudinally within a groo've in said casing, and engaging with the edge of said saddle, substantially as and for the purpose set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 21st day of June, 1875. p
