Figs. 15 and 16 are sections similar to Fig. 11, showing modified forms of my invention.

, Having reference to the drawings in detail, the

numeral I represents the top of a desk, table,

or other fiat object onto which a sheet of paper i6 is placed which is to receive the imprint negatively applied to the reverse side of a master sheet or card anddisplay the same in positive form.

Where hereinafter reference is made to a sheet of paper it is intended to include a post card or other card, or any object having a surface capable of receiving the imprint from a master sheet or card.

" .In Fig. '7 of the drawings, the master sheet or card is designated by the numeral l1 and it may .l'iere'be stated that prior to placing the master sheet or card upon the sheet of paper,'the area of the latter which is to receive the imprint is moistened by moving the moistening element of the device in contact with the face of the sheet .of paper and placing the master sheet or card upon the moistened area of the sheet of paper bodily as a unit over the surface to receive the imprint from the master sheet or card,'said two parts being connected together so that they have relative movement sufficient to control the delivery of a solvent or other liquid fromone part 7 of the device to the other.

' In the particular embodiments of my invention shown in the drawings, the part I8 is in the form of a liquid-container serving as a hollow handle for the device, while the part [9 is a housing transversely-widened and pivotallyconnected to the adjacent or inner end of the liquid-container or handle. The latteris in the form of a tube closed at its inner end, as at 20, and open at its outer end to receive a closure or cap 2! which has an inwardly-extending flange 22 threaded hintosaid open end and between said cover and the edge of said tube a washer 23 is clamped. The cap therefore closes the open outer end of the liquid-container or handle in a water-tight manner. The closed or inner end of the liquidcontainer or handle is provided with a liquid escape passage or opening 2a. The closed inner 'end of the liquid-container or handle extends into the housing l9, which for convenience I term the This housing or head is of parti-circular formation in cross section and it has an opening 25 formed in its peripheral wall 26 through which the closed inner end of the liquid-container or handle extends.

The opposite side walls 27, 28 of this head 28 and the extended portions of said side walls serve as lugs or bearings 32 between which a moistening-roller 32% is rotatably arranged, the roller being secured to an axle 34 having its ends journaled in said lugs or bearings. The front end of the semi-circular re-entrant wall 33 also terminates a distance above the lower edges of said side walls for a purpose to appear hereinafter.

The tubular liquid' container or handle [8 is preferably flattened along its lower portion or I underside at the inner end thereof, as at '35, and extending downwardly from said flattened portion are webs 36 and pivot lugs 37 formed as continuations of said webs; said webs and lugs being so spaced apart that their outer'sides lie in free moving relation to the inner surfaces of the side walls 27, '28, and pivots 32 ar passed through said lugs and through said side walls to pivotally connect the liquid-container or handle 18 and the housing or head It together.

Normally the lower edges of the webs 36 lie against the upper edge of the peripheral wall 26 forming the bottom of the opening 25 and these webs are so maintained by means of a combination spring-device and valve to be presently described.

Arranged for rotatable movement within the semi-circular roller-receiving pocket 3 l. is a pressure-roller 39 which is secured to an axle 4i] having its ends journaled in opposite side walls 2?, 28 of the housing or head [9. The axis of this roller is in rear of the moistening roller or element 33 and in planes forwardof and beneath the pivots 38.

The moistening-roller 33 and the pressureroller 39 are preferably formed of rubber, but any other material suitable for the purpose intended maybe used for these rollers. p

The pressure-roller is considerably larger than the moistening-roller and normally the relationship of these rollers, when the parts are in normal position, is such that the pressure-roller will be in contact with the support on which the device rests, while 'the .moistening-roller will be spaced from the surface of such part.

The inner closed end of the. liquid-container or handle is provided with a forwardly projecting liquid-discharge nozzle 4| through which the liquid-escape passage or opening 24 extends; said nozzle. having an inclined upper face 42 which is separated from the under side of a lip 43 extending forwardly from the closed end of the'liquid-container or handle l8. The liquidescape passage or opening 24 has its exit or outlet at the inclined upper face 42 of the nozzle and the end faces of the lip 43 are alined with the outer faces of the webs 38 and lugs 3'1 and thus occupying the full width of the space between the side Walls 21, 28 of the housing or head.

thereof. Thus the area of the paper orother material to receive the matter by transfer from a master sheet will be evenly dampened and a perfect impression assured.

In the modification shown in Fig. 16, in addi tion to the liquid-escape passag 24, I provide an air-inlet passage 54, preferably parallel with the liquid-escape passage, and both of which open into a larger passage, 55 at the outer end of the liquiddischar e nozzle 4|. In this manner,:when. the combined spring device and valve is unseated in the manner shown in Fig. 16,, air enters the liquid chamber through the air-inlet passage 54 and assures a free flow of liquid from the vliquid chamber through the liquid-passage 24. This air-inlet passage 54 may beutilized in the preferred construction and also in the various modifications; and although feeding of liquid fromthe liquid chamber will occur without the use of an air-inlet passage, a more constant flow of liquid is assured by the use of the same.

Having thus described my invention, what I claim is:

1. In a device of the kind described, two pivotally-connecte-d parts relatively movable and movable together as a unit, one of said parts being in the form of a hollow head having an opening in its peripheral wall and the other being an elongated tubular element having one end entered in said head through said opening and pivotally connected thereto, said elongated tubularelement containing a transfer-inducing liquid and having a liquid-escape passage through said entered end, a resilient valve between the entered end of said elongated tubular element and the peripheral wall of said hollow head forward of said end to normally close said liquid-escape passage and simultaneously maintain said pivotallyconnected parts in a normally predetermined relation to prevent feeding of the transfer-inducing liquid, a moistening element carried by said hollow head and positioned underneath said resilient valve and forward of the axis of the pivotsconnecting said parts so that said hollow head is caused to swing on its pivot out of its normal predetermined relation with said elongated tubular element and opensaid liquid-escape passage to supply said moistening element with liquid when said moistening element is pressed against and moved over a surface to be moistened, said resilient valve serving to swing said hollow head into its normal position when the pressure against said surface is relieved, and a pressure element in rear of said moistening element having its axis in planes forward of and beneath the pivots connecting said two parts together so that said two parts remain in their normally predetermined relation under pressure exerted by said pressure element against a master sheet or card and said liquid-escape passage remain closed. r
