DUPLICATING DEVICE.

Applieation filed March 17, 1926. Serial No. 95,434.

The object of this invention is to provide a hand duplicating device by means of which a large number of copies maybe made from a wax stencil. without the necessity of employing more or less expensive apparatus. or apparatus which is not readily portable.

A further object is to provide a (l8Vl('6 of the type indicated, which shall include a block mounting a handle and a plurality of ink fountains adapted to feed ink thru a. pad to which the ink is evenly distributed, and which is properly protected, the ink flowing thence to the stencil, in sufiicient quantity to provide an impression of the required clearness, without interfering with the quick drying of the printed sheets.

A further object is to provide particular means for mounting the detachable elements of the device.

With the foregoing and other objects in view, the invention consists in the novel construction and arrangement ofelements described, illustrated and claimed, it being understood that modifications may be made within the scope of the claims, withoutde parting from the spirit of the invention.

' In the drawingsforming part of this application, Figure 1 shows the device in side eleva- {ion, with the ink feeding means in dotted mes.

Figure 2 is a perpsective view, showing-- one end portion of the block, and showing especially the relative position of the two ink fountains, and the spring held bar at one end of the block.

The device herein described is capable of producing between one thousand and fifteen hundred copies, and if sufficient care is taken of the wax stencil a larger number may be printed.

The blOck 10 has secured to the upper surface thereof a handle 11, and the lower surface of the block is curved, and provides an even printing surface of rocker form, from which results similar to those obtained from a cylinder machine, may be realized. Two ink receptacles or fountains 12 are provided, and these receptacles are each closed by a cap such as 13, the ink being distributed thru channels or bores such as 14, which may be positioned about as shown with reference to the lower surface of the block, on

each side thereof, that is, on each side of the central longitudinal axis.

The lower surface is covered by two layers" of felt designated 15, and below the latter is a layer ,of pure linen designated 16, in order that no particles of felt may pass to the openings thru the stencil to be mounted below the layer of linen. The ends of the felt layers, and the linen layer, drawn tightly befole being fastened, are secured under metallic bars or strips, designated 18 and 19. these strips being secured by screws 19'.

The wax stencil 20 carries a strip of cardboard on one end thereof, for reinforcing purposes, the stencil and strip being apertured, and the apertured portions being designed to pass over screws 21 whichhave their heads projecting from the right hand end of the block 10. It will be observed that the block at this end is provided with a cutaway portion affording a straight shoulder at 22, and the opposite end is also cut away providing a transverse groove as shown at 23. Within this groove 23, I mount a rod or bar 24, having 'a rubber cover 25, the ends of the bar being adapted for connection with coiled springssuch as 26, se-

cured at 27. The bar or roller thus provided and including the elements 24 and 25, is adapted to resiliently engage the endof the Wax stencil 20, at this end of the block,

' the stencil extending into the grooved por-.

tion 23, andbeing there engaged by the roller just referred to.

Havng thus described the invention, whatv is claimed is:

1. In a device of the class described, a

block having cutaway portions beneath the endsthereof, and extending transversely of the block, providing shoulders, fibrous sheets connected with the block beneath the shoulders, a stencil below the fibrous sheets and having one end detachably connected with the block above the shouldered portion, the

other end of the stencil entering the (-ut-.

away portion adjacent to the other shoulder,

a transverse element engaging this end of the stencil, and movable outwardly from the end of the block, and tension springs, ex pansible independently and longitudinally for holding the transverse element and stencil in position by engagement with opposite ends, and permitting independent movement of the ends of the transverse element.

-2. In a device of the class described an element having a lower curved surface and openings therethrough, a handle connected with this element one outer end of said 5 element being grooved transversely, a fibrous inking. sheet extending over the curved surface, means for detachably connecting a stencil with the other end of said curved element, a roller cooperating with the transverse groove and longitudinally expansible springs independently engaging opposite ends of the roller for resiliently retaining the roller and holding the adjacent end of the stencil in the groove.

In testimony whereof I affix my signature.

HARRY SPURRIER.
