HAND-STAMP.

SPECIFICATION forming part of Letters Patent No. 613,721, dated November 8, 1898. Application filed December 8, 1897- Serial N01 661,181. (No-model.)

To all whom it may concern.-

Beitknown that I, GEORGE ADAM RENrsoH- LER, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Hand-Stamps, of which the following is a specification.

This invention pertains to improvements in hand-stamps such as are used, forinstance, for mail-canceling purposes.

The improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in Whicl1 Figure 1 is a vertical section of a handstarnp exemplifying my invention, the section being takenin the plane of line a of Figs. 2 and 3; Fig. 2, a view of the lower or type end of the stamp; Fig. 3, a horizontal section in the plane of line Z); Fig. 4, aside elevation of one of the inside date-types, and Fig. 5 a similar view of one of the outside date-types.

In the drawings, 1 indicates the handle; 2, a ferrule thereon; 3, the head-piece of the stamp, the same being removably screwed into the ferrule; 4, a deep cylindrical bore in the lower end of the head-piece; 5, a helical spring disposed within this bore and abutting against its roof; 6, a washer disposed loosely in the bore of the head-piece and bearing against the lower end of spring 5; 7, a circum ferential series of type, each of segmental cross-section, this series of type forming a sectional hollow cylinder fitting within the bore of the head-piece below washer 6, the upper end of the types bearing against the washer and the lower ends of the types bearing the printing characters, of which characters there may be one or more on each of the segmental types, the exemplification showing each of the segmental types as bearing two characters, except as to the blank spaces represented by quads of segmental section, it being understood, however, that all of the segmental types may bear characters if the extent of the reading matter requires it; 8, a downwardly-presenting shoulder at the lower end of each of the segmental types '7 9, a keeper-nut screwed onto the lower end of head-piece 3 and having at its lower end a flange surrounding the lower ends of the segmental types 7 and engaging upwardly against shoulders 8, whereby all the segmen tal types are held with their faces in a com= mon plane, spring 5 pressing the types down as far asshoulders 8 will permit; 10, a setscrew serving as a lock for nut 9 to keep it from unscrewing from the head-piece; 11, a dowel-pin projecting from the outer surface of one of segmental types 7 into loose engagement with a keyway in the bore of the head-piece, this dowel-pin preventing the rotation of the circular series of types within the head-piece; 12, a hollow cylinder disposed concentrically within the series of segmental types 7 and open at its lower end;

13, a shank projecting from this cylinder up through the roof of the head-piece; 14:, a nut screwed upon shank 13 and serving to hold hollow cylinder 12 firmly in the head-piece;

15, a pin doweling hollow cylinder 12 against rotation within the head-piece; 16, a helical spring disposed just within the wall of hollow cylinder 12 and abutting against the roof of the bore of the hollow cylinder; 17, a washer loosely disposed within the bore of the hollow cylinder and bearing against the lower end of spring 16; 1S, date-types fitting loosely within the lower end of the bore of hollow cylinder 12, at opposite sides of the cylinderbore, these date-types being herein termed the outside date-types; 19, a pin removably inserted diametrically through the walls of hollow cylinder 12, near the lower end of the cylinder, and passing through holes in date-types 18, the holes for the pin being vertical slots wider at their lower ends, as seen in Fig. 5, the upper ends of the slots being in position to bear down on pin 19 when the faces of the date-types are in the same plane as the faces of segmental types 7 20, a pin disposed o diametrically across the bore of hollow cylinder 12, under washer 17, and limiting the descent of that washer under the influence of spring 16; 21, Fig. 5, prongs formed upon the upper edge of outside date-types 18, at the side extremities of those date-types, these prongs straddling pin 20 and bearing upwardly against washer 17, the prongs being of such length as to always bear against washer 17 and permit the date-types to rise somewhat I60 in hollow cylinder 12 and push washer 17 upwardly against the resistance of spring 16; 22, a second helical spring disposed within hollow cylinder 12, inside of spring 16; 23, a plug loosely disposed within washer 17 and bearing upwardly against spring 22, spring 22 thus holding the plug down upon pin 20; 24c, date-types disposed within hollow cylinder 12, between outside date-types 18, and having similar slotted holes engaging pin 19, the date-types 24E being herein termed the inside date-types, which inside date-types are similarly provided with prongs 21, Fig. 1, straddling pin 20 and reaching up into contact with plug 23, the prongs upon the inside date-types being disposed inwardly, so as to pass freely within washer 17, so that the inside date-types can rise, against the resistance of spring 22, independently of washer 17 and the outside date-types; and 25, a thin cylindrical sleeve disposed loosely around spring 22 to prevent that spring becoming entangled with spring 16.

Segmental types 7 fit and fill the bore of the head-piece around hollow cylinder 12, but so loosely as to permit of the types sliding freely endwise with reference to each other. Spring 5 permits these types, or any one or more of them, to yield upwardly, the result being that the types are adapted to take a fairly even bearing on an uneven surface. The segmental types are thus adapted to give an improved character of impression upon surfaces formed of overlapping papers, as in the case of envelop-flaps on letters, postage-stamps on letters, &c., and to compensate for inequalities of surface due to the character or position of the contents of an envelop-as, forinstance, where a folded letter within an envelop does not fill the envelop-thus requiring an impression to be made upon the surface backed in part by two envelop thicknesses only, while in other parts it is backed by those two thicknesses plus the thickness of a folded letter or perhaps of cards or other comparatively small matters inclosed with the letter.

In hand-stamps for postal purposes the readin g matter (represented by the circular series of segmental types 7) will generally beretained unchanged; but if it be desired to change this reading matter it is only necessary to unscrew nut 9 and take out type 7 and sub- I stitute a new circle of types with the desired characters.

lVhile the circle of types 7 is composed of types of segmental cross-section, the

datetypes

18 and 24 are fiat and are held in the hollow cylinder 12 by the pin 19. These types may require frequent changing, which changing is to be eifected by unscrewing handle 1 and then unscrewing nut 14 far enough to allow hollow cylinder 12 to come out of the head-piece far enough to permit the with drawal of pin 19, thus allowing the date-types to be removed and new ones placed in position. If desired, nut ltmay be entirely removed from the stem of the hollow cylinder,

of types used alone. 1 by unscrewing nut 14 the central portion of l the stamp may be removed and replaced by thus allowing the hollow cylinder to be bodily removed from the head-piece for convenience in changing the date-types. The date-types are to fit the hollow cylinder so loosely as to be capable of free vertical play therein with reference to the hollow cylinder and to each other, and it is also desirable that the datetypes fit the hollow cylinder edgewise so loosely as to permit them to partake of some rocking motion. The result of this is that the date-types may move upwardly a trifle against the resistance of their springs and also rock somewhat, thus permitting these date-types to also accommodate themselves to uneven surfaces on which they are to make impressions. Each of the date-types maybe in a single piece, or, if desired, each date-type may be formed in two pieces, as in Fig. at, in which latter case each half of each date-type is capable of in dependent vertical yielding. The slots in the date-types are narrow in their upper portions, as seen in Figs. 4 and 5, so that normally they fit down fairly upon pin 19; but being wider at their lower portions there is some slight capacity for side motion and rocking when the types shall have moved upward with reference to the pin.

It is obvious that the segmental types and their holding devices may be omitted and the date-types used alone, or that, on the other hand, the date-types and their holding devices may be omitted and the circular series It is also obvious that another central portion bearing a different impression device, the system thus providing a very convenient means for readily chang ing the entire central portion of a stamp.
