Specification of Letters Patent.

Patented July 9, 1918.

To all whom t may concern:

Be it known that we, BEVERLY P. Evans and ALEXANDER M. FISHER, citizens of the llnited States, residents of Washington7 in the District of Columbia, have made a certain new and useful Invention in Hand- Stainps; and we declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to ltheI accompanying drawings, and to letters or ligure-s of reference marked thereon, which form a part of this speciiication.

Figure l is a perspective view of the invention.

Fig. 2 is an end view of the same.

Fig. 3 is a detail cross section of the clasp member, the pad, and the pattern sheet.

Fig. el is a detail perspective view of the handle.

llig. 5 is a similar view of the clasp member and the pad.

lFig. G is a detail plan view of the pattern sheet.

VFig. 7 is an end view partly broken away of a modification.

llig. 8 is a fragmentary detail cross section of the pad and the pattern sheet.

Fig. 9 is a detail perspective View of the ink pad carried by a separate device.

The invention h as relation to hand stamps, having for its object to provide a stamp having a pattern sheet quickly interchangeable with other and different pattern sheets, each of said sheets capable of being made up and placed in the stamp as required in a few minutes time. A further object is to provide a fountain stamp of the character stated, having a constant ink supply to the pattern or wording. Other objects and advantages will hereinafter appear.

The invention consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, lthe numeral 2 designates a handle; 3 a printing pad, and 4 a stencil or pattern sheet, usually of flexible paper or thin sheet material of suitable character, upon which the required wording of the stamp is written or impressed in a typewriter or by hand in such manner as to cut through the material of the sheet and form a stencil, through the pattern of which the ink will flow from the pad at the back of the stencil, when pressure is applied to the stamp5 in use.

It is designed, in the application of the iiexible stencil sheet to the ink pad borne by the handle, that the material of the sheet shall be stretched smoothly across and in close engagement with the pad, by tension exerted upon the lends of the sheet.

rThis is preferably accomplished by malring the connection between ink pad and handle through the medium of a channeled clasp member 5, within the channel 6 of which closely lits the bottom of the handle, said bottom being usually laterally extended, as shown at 7, to engage an elongated clasp 5.

The stencil sheet is laid under and across the inl; pad, the sides of the sheet extending upwardly along and over the tops of the sides of the clasp, within the channel thereof.

rIhe handle bottom 7 being then pressed within the channel G will engage at its sides the upper free ends of said sheet and press the same downwardly, thereby stretching the sheet smoothly across the ink pad.

Another way in which the same result may be accomplished is shown in Fig. 7 of the drawings, wherein the ink pad is borne directly by the handle bottom, the stencil sheet being laid under and across said pad and at its sides extending upwardly along the sides. of said bottom, an elastic clasp member 8 being slidably engaged with the sides of said handle bottom, thereby exerting tension upon the free ends of said sheet to stretch the sheet as stated.

The channeled member 5 is usually made of sheet metal, the ink pad being suitably connected thereto, as by cementing or sewing, and the upwardly extending sides or flanges 6 of said member having an inherent spring action to clasp the handle bottom 7 and the ends of the stencil sheet located between said bottom and said flanges.

The ink pad may be carried by a separate device 9, having pliable metal ends 10, designed to be bent over the base of the clasp member 5. In this way provision is made for the application of new pads as the old ones become exhausted or worn out.

To obtain the best results it is desirable that the lower face of the ink pad shall be of a material having a nap or pile that will project outwardly within the perforations or cuts of the stencil sheet, and thereby better serve to car-ry and apply the ink of the pad through said perforations to the surface upon which the stamp shall be impressed.

In utilizing the inking ad as a backing or reinforce for the stenciFsheet a constant ink supply is provided to the pattern thereof.

The ink pad is preferably made of a material, such as wool, which is neitherv soluble nor softened by the ink absorbed, whereby the4 wool fibers or nap, projecting through the perfor-ations of the pattern sheet will better serve theirl purpose.

The pad preferably contains ink, stated, but other material or powder may be substituted, capable of making a legible or useful impression through the perforations or cuts of the pattern sheet.

Ijn the use of they stamp, the ink pad is compressed and the ink expressed therefrom through the perforations of the pattern sheet in making the impression or printing. The pressure upon the pad being released the pad will expand to normal condition and suck up or absorb the excess ink.

We claim:

l. In a hand stamp, a channeled member carrying a printing pad, a pattern sheet located beneath said pad and having its free ends extending upwardly and reversely within the channel of said member, and a handle engaging the side walls of said channeled member to secure said sheet in position.

2. In a hand stamp, a handle member, a clasp member, one of said members carrying a printing pad, a pattern sheet engaging the pad and located at its ends between the 3. The combination with a hand stamp, Y

comprising a handle member and a clasp member bearing a pad, of a pattern sheet underlying the pad and having opposite edge portions thereef fitting between the members, the latter slidably engaged one with the other and with said edgeportions of the pattern sheet to secure the sheet in proper relative position.

4L.A The combination with a hand stamp, comprising a handle member and a channeled clasp memberl bearing a pad, of a pattern sheet underlying the pad and having itsy upper free edge portions extending reversely within the channel o-f the clasp member and between the latter and the handle member, the members slidably engaged one with the other and with said edge portions of the pattern sheet to secure the sheet in proper relative position.

5. The combination with a hand stamp, comprising a handle member and a clasp member, one of the members bearing a pad, of a pattern sheet underlying the pad and opposite edge portions thereof fitting between the members, the latter slidably engaged one with the other and with said edge portions of the sheet to secure the sheet in proper relative position and stretch the same across the pad.

In testimony whereof we aflix our signatures in presence of two witnesses.
