and an integral part of the stencil itself; to prom,

vide an improved stencil comprising an integral proof card on which the stencil impression is formed simultaneously with the cutting of the stencil; and to provide an improved hand stamp stencil that may be easily cut and applied and which can be readily replaced or renewed at negligible cost.

specific embodiment of this invention is showri'in the accompanying drawing. wherein:

11F. Eure; 1 is a sectional side elevation of the improved hand stamp.

Fig. v2 is a perspective view showing the improved hand stamp and its associated parts.

Fig. 3 is a perspective view of the improved stencil.

, Fig. 4 is a perspective view showing the improved stencil after it has been cut and prepared for use on the hand stamp, andl Fig. 5 is a perspective view of a modied form of the improved stencil.

In the form shown in the drawing, the improved hand 'stamp is of the reservoir type and comprises a body member I having an upwardly extending handle 2 and a resilient. base or bottom portion 3 made of sponge rubber, or other suitable material in which an inking pad 4 is recessed so as to be ush with the bottom face of the resilient base member 3. i

The handle 2 is hollow to provide a cavity 5 which serves as a reservoir for ink, access to the cavity ,5 being had through a removable cap 6 at the topend of the handle 2. A tube or passage` way 1 leads from the ink reservoir 5 to the ink pad v4.and is of substantially capillary size so as Atoaiitord a constant supply of ink to the ink pad .f4 for` impression purposes.'

As vshown the lower face of the resilient base member 3 has its margin cutaway so as to provide a right-angled recessed shoulder 8V surrounding a projecting portion 9 which into the ink pad is recessed, the surface of the ink pad 4 being substantially flush with the lowermost surface of the projecting portion 9.

As shown in Figure 1, a stencil I0 is disposed over the ink pad 4 and the projecting base portion 9 and the margins of the stencil I0 are clamped against the shoulder 8 by means of a frame-like clamping member I I having an opening I2 through which the projecting base portion 9 may pass. The clamping member II is larranged to seat squarely onthe shoulder 8 and is provided with upwardly extending side mem.-

bers which fit against the sides of the hand stamp body I and the resilient base portion 3 thereof.

As shown in Figure 2 the upstanding end members I3 of the clamping member II are arranged to extend along the end walls of the hand stamp body I and provide resilient tongue portions I4, each having an aperture I5 to receive a locking pin I6 projecting outwardly from the end walls v of the body I. This arrangement will securely hold the clamping member in stencil clamping position against the bottom of the hand stamp and prevent inadvertent loosening or dropping resilient lower portion 3 thereof, and to hold a I proof card I8 which is an integral part of the stencil I0, tightly against the side wall of the hand stamp. The element I1 is arranged to frame the card I8 so that a proof impression of the stencil made on the card I8 will at all times be visible to the user of the hand stamp.

Thus when the hand stamp, stencil and clamping member are assembled, as in Figure 1, a com,- plete stamping device will be had which will perform perfectly all of the functions of the usual hand stamp having permanent cut-out rubber type or impression elements, with the added advantages, however, that the stencil impression member can be readily, and cheaply changed or renewed and-a proof of the stencil will at all times be visibleas an indicating means showing the nature of the impression that the improved hand stamp will make.

'I'he improved stencil shown in Figures 3 and 4 comprises a backing member or card on the face bottom tab portions I! and 20; respectively,

which are arranged to be removed after the stencil has been cut suitable lines of perforations 2i and 22, orthe like, being provided to facilitate removal of the top and bottom tabs I9 and 2l.'

As shown in Figure 3 the stencil I0 which may be of any suitable stencil material, such asv that well known in the art wherein one side of the stencil is provided with a coating which breaks away from the stencil along the lines of any impression made on the opposite face of the stencil sheet, is secured at its upper and lower edges with its coated side against the backing member or card.

The upper edge of the stencil I is secured to the lowermost margin of the top tab I9 immediately above the line of perforations 2l and the said perforations are made so asto pass through both the stencil sheet and the backing member or card, the coated side of the secured upper margin of the stencil sheet being against the top tab I9.

The lower margin of the stencil sheet I0 is securedto the proof card portion I8 of the backing member immediately above the lower line of perforations 22 and in this instance the stencil sheet is looped under so that the front or uncoated side of the stencil sheet will lie against the backing member.

In forming the loop 23, a certain amount of slack is left in the stencil sheet I0, as shown in Figure 3, so that the improved stencil and its backing card may be passed around the platen of a typewriter without any danger of the stencil side wall of the hand stamp base member 3 on the side opposite the location of the proof card I8 so as to facilitate placement and proper alignment of the stencil on the hand stamp after the stencil has been cut. Also, if desired, the face of the stencil I0 may have that portion which will voverlie or register with the ink pad 4 outlined by suitable means such as printed lines, as shown at 26 in Figs. 3 and 5, to indicate the limits within which the matter cut in the stencil must lie in order to be located within the area of the ink pad.

In the form of stencil shown in Figure 3 the coating on the rear side of the stencil sheet Ill is of a type which will leave an impression on the backing card I8 when the stencil is cut, whether the cutting be by means of a typewriter or by a manually operated stylus. 'I'hus as the stencil is made, an exact proof of the cutting will be provided on the portion I8v of the backing member.

In use, after the stencil has been cut, the top tab I9, together with the upper margin of the stencil sheet I0, is torn away from the remainder of the stencil and backing card along the line of perforations 2| and the bottom tab 20 is removed by tearing along the line of perforations 22 which are located just below the lower margin of the proof portion I 8 where the bottom margin of the stencil sheet I0 is secured. The stencil I0 and attached card I8 are then placed on the hand stamp with the stencil portion Ill turned under relative to the proof card I8, and overlying the ink pad 4, and with the coated side of the stencil exposed. l

The apertures 24 in the stencil I0 are hooked over the pins 2B and the proof card is laid against the opposite side of the hand stamp body. Then the'clamping member II is applied to secure the stencil III in place against the ink pad 4 and to hold the proof card tightly against the side wall of the hand stamp body.

As shown, the margins of the stencil I0 extend beyond the edges of the projecting portion 9 of the resilient base 3 of the hand stamp body and are engaged by the clamping member II so as to be held tightly against the shoulder 8. v.Thus the stencil is drawn tautly 4across the ink pad portion of the hand stamp and with the clamping member locked to the hand stamp body by means of the end pin I6 engaging in the aper, tures I5 of the tongues I4l the hand stamp is ready for immediate use.

The modified form of stencil, shown in Fig. 5, is of the same construction as the stencil shown in Figures 3 and 4 except only that the coating on the back side of the stencil sheet I0 is of the type which does not leave an impression on the backing member. In this form of stencil, a sheet of carbon paper or other suitable transfer means 2l is provided between the looped stencil sheet III and the backing member so that as the stencil is cut, the proof impression will be made simultaneously on the proof card portion of the backing member. Thus the improved stencil' may be made with either the transfer type of stencil coating or the non-transfer type and yet accomplish the desired`function of providing an integral proof card made simultaneously with the cutting of the stencil itself. The transfer means 21 is discarded as soon as the stencil is cut, being readily removed when the tabs I9 and 20 are torn off to prepare the stencil for use.

In the operation of the improved hand stamp and stencil the ink pad 4 is supplied with ink from the reservoir 5 in the handle 2 and with the stencilv in place on the hand stamp an imprint of the matter cut in the stencil will be made when the stencil-covered face of the hand stamp is pressed against the surface on whichthe stencil impression is desired; the ink from the ink pad 4 passing through the cut portions of the stencil sheet I0 from which the coating on the back side has been removed during the stencil cutting operation.

The resilient lower member 3 of the hand stamp body assures that the entire face of the stencil will be uniformly impressed against the surface on which the impression is desired; and will also permit compression of the ink pad 4 so as to force the ink through the cut-out portions of the stencil sheet I0. As the hand stamp is released from the surface on which the impression is made, the resilient portion of the hand stamp'body will return to its normal form allowing expansion. of the previously compressed ink pad 4 and thereby causing a new supply of ink to be drawn from the capillary passageway 1 into the ink pad 4.

The main advantages of my invention reside in the fact that the improved stencil stamp, unlike the ordinary rubber stamp, is flexible and variable in its use. The stencil may be changed at will to provide a hand stamp capable of making an iniinite variety of impressions and the stencil may be made to incorporate designs and fac' simile signatures which if reproduced in the ordinaryrubber stamp would be quite costly.

Other advantages reside in the simple and low proved stencil construction wherein a proof card permanently attached to the stencil itself is made at the time the stencil is cut and without any` duplication of effort or operation, such proof card serving as an identification of the cut stencil whether'the stencil is applied to the hand stamp or whether it is placed in a file for future use,`

during the entire 1ife of the stencil.
