IMPROVEMENT IN S TENCILPLATEE 4113119 Schedulexefened to in these `Letters Patent and making part-of the same.

To all whom tt may conce/rn.-

Be it known that we, JEROME L. TARBO'X and H.'

.L TARBOX, of New York, in the county of New York,

and State of New York, have invented a new and useful Improvement in Stencil-Plates; and we do hereby declare that the following is a full, clear, and exact de scription thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part 0f this specification.

This .invention relates to improvements in -stencilplates, designed to provide a simple and convenient arrangement whereby the stencil-letters maybe readily connected together, for forming words, and be as readily disconnected, for changing their combination, without the. employment of frames for holding them when 4set up, ass now commonly practised.

Figure l represents a plan View of our improved arrangement, and A Figure 2 represents a perspective view of the same. Similar letters of reference indicate corresponding parts. 4 f We provide each plate, A,Awherein a letter is formed, with the bent-springs A', having two .or more sets of notches, B.

The said springs are secured to the top of theplates, near the ends, and projecting over one edge thereof.

We also provide thesaid plates with the hoods O, on the opposite edges of'the plates Afhaving openings in their outer ends, and catches, D, capable of engaging thenotches in the springs.

One edge, E, of the plates is elevated, while the other, F, projectssuiciently to lap under the edge E when they are connected together.

When th plates are arranged together, to form a word or combination ot" letters, vthey are placed side by side, and the springs A of one plate pressed into the hoods O, until the notches in the said springs engage the catches D, whereby they are held firmly together, and the edges lapped, so that the ink cannot pass between the plates.

If it be desired to arrange the letters in curves, two or more sets oinotches, B, may be made in the springs, and the innermost set engaged with the catches D at one end, and the outermost at the other. Y

In order to connect them, so as to form two or more rows, we provide the loops or eyes G, at each end of the plates, and connect -the rows together by a wire passing through the said eyes. Instead, however, of the eyes, spring-catches, or other similar'devices may be employed.

To disengage the plates for changing the combinations of letters, the'sprngs A', the ends of which project vslightly beyond the hoods, are pressed down sutliciently to disengage the notches therein from the catches D. v

. Other arrangements of the springs A', and their catches, may be employed with good results, but we prefer the plan which we have described.

l'. Stencil-letters, arranged to be readily connected vor disconnected, by springs on one section taking into notches, or behind projections on the other sections, substantially as specified.

2. lThe arrangement ofthe springs A', hoods C, and catches D, substantially as specified.

' 3. The plates A, arranged for lapping the thereof, substantially as specified.

4. Stencil-plates, arranged to be united to form rowg by means of the loo s G, and rods or equivalent devices, substantially 'as specified.

The above specification of our invention signed by us, this day of 1869.
