UNITED STATES PATENT OFFICE.

CHARLES E. MARSH, OF LYNN, MASSACHUSETTS.

FRAME FOR HOLDING STENCILS.

SPECIFICATION forming part of Letters Patent No. 375,371, dated December 2'7, 1887.

Application filed December 1-1, 1886. Serial No. 221,288. (No model.)

T 0 0.25 whom it may concern:

Be it known that I, GnARLEs E. MARSH, of Lynn, in the county of Essex and Common wealth of Massachusetts, have invented a certain Improved Frame for Holding Stencils, of which the following,taken in connection with the accompanying drawings, is a specification.

This invention relates to means for holding stencils, and the nature thereof is hereinafter fully described and specifically claimed.

Referring to the drawings,Figure 1 is a plan view of my improved frame and two stencils. Fig. 2 is a cross-section on line a: a: of Fig. 1.

The plate A is preferably composed of a very thin sheet of metal with its edges folded or lapped over on one side to form a kind of stay-rod, a a, which serves to prevent the sheet being bent. The rods or strips 6 e are also formed by cutting through the plate A, then folding it back and over upon itself, so as to leave grooves fiadapted to hold the sten- (il,and leave apertures in the plate A,through which the stencil may be exposed directly to the mark-receiving surface. The manner of folding the laps e and the holding of the stencil are best shown in Fig. 2. The laps 6 further serve to strengthen and stay the plate A and prevent it from bending. The end of the stencil is preferably allowed to extend under the fold a, as shown in Fig. 1, to the end that it may be pinched and held in position while the operation of marking is being performed.

The frame represented in the drawings is arranged to hold two stencils, B B, though a frame for holding one stencil may be constructed, if desired. In such case the advantage would be mainly the ability to use economy in the manufacture thereof.

small stencil sheets, and consequently an W'hen the frame is arranged for holding two or more stencils, a greater variety of arrangement and utility is obtained. Small stencils may be used, either of which may be removed independently, and the aperture left open or a different stencil substituted in place of the one removed; so, too, the marking may be distributed about in different lines or places on the marked surface,and other advantages may result, many of. which are obvious to persons skilled in the art to which this invention pertains.

I have described the frame A as composed ofa single piece of material; but I am aware that it might be composed of separate pieces brazed or otherwise secured together.

I am aware that it is not new to provide a stencil-holder with folds about its edges and to insert the stencils under said folded edges, and I do not claim any such idea.

I claim and by Letters Patent desire to secure- A stencil-holder consisting of a sheet-metal plate having apertures formed in its body portion, strips or folds e ealong said apertures, adapted to receive and retain the edges of the stencil, and the fold orstrip a, extending at right angles to the strips 6 e and adapted to receive the ends of the stencil, substantially as described.

CHAS. E. MARSH.
