JOHN T. WRIGHT AN OLIVER G. BRYANT, OF CHICAGO, ILLINOIS; SAID WRIGHT ASSIGNOR TO SAID BRYANT.

.- IMPRovEMENT IN sTi-:NiL-PLATES.

Specification forming part of Letters Patent No. l8,395, dated January 16, 1877; application filed March 2 2, 1876. i

To all whom it may concern:

Be it known that we, J oHN T. WRIGHT and O. G. BRYANT, of Chicago, in the county of Cook, andin the State of Illinois, have invented certain new and useful Improvements in Stencil-Plates; and do hereby declare the following' is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making a part of this specification, in which- Figure 1 is a `perspective view of our im'- proved stencil-plates before being combined. Fig. 2is a plan view of the same with their interlocking edges just entering into engagement with each other. Fig. 3 shows said plates as combined and in relative position for use, and Fig. 4t is a cross-section of the same.

Letters of like name and kind refer to like parts in each ofthe figures.

In the use of stencil-plates in which the letter-plates are combined by turning their edges backward, and causing said edges to engage with each other, it is necessarythat said letter-plates should be united by placing the lower end of the engaging-edge of one plate within the upper end of the engaging-edge of the contiguous plate, and then moving said first plate downward until its upper and lower edgesare in line with the corresponding portions of saidsecond plate.

The operation described requires considerable skill and patience, for the reason that the engagingedges are made to fit closely together, and it is dificultto cause the end of oneA edge to exactly coincide with and enter the end of another edge.

To obviate this objection, and to increase the ease and facility with which the letterplates may be combined, is the design of our invention, which consists, as a new article of manufacture, in a stencil-plate having one or both of its side edges turned backward, so as to enable it to engage with the corresponding edge of another plate, and having one corner of such backward-turned portion cut away, substantially as and for the purpose hereinafter specified.

plates, so as to form a word or words.

In the'annexed drawings, A represents a stencil-plate of any suitable size, `which contains a letter or character, and is designed for use by combining it with other similar One side edge, a, of the plateA is folded backward upon the lower side, and the other edge,

a', is folded backward upon the upper side of n said plate, and the rst-named edge is preferably raised, as shown in Fig. 4, so as to enable it to contain the edge a of another plate, and bring the lower faces of said plates iush with each other.

As thus constructed, two plates, A and A,

are combined by causing the lower end of one engaging-edge, a, to engage with the upper end of the edge a of the opposite plate, and thus moving said plates longitudinally until hey occupy the relative positions shown by ig. 3. f In order that the operation of engaging the edges of the plates may be rendered easy, the upper portion of each rearward-turued edge a is cut away obliquely, as shown in Figs. l and 2, by which means the upper face of its plate furnishes a guide in one direction for the edge a of the adjacent plate, while the oblique portion a of said edge a operates as a lateral guide for said edge a, and enables the latter to be easily and quickly placed in engagement with the former.

This improvement is more especially useful when the plates have become gummed up by use, land their engaging-edges more or less filled with ink.

Having thus fully set forth `the nature and merits of our invention, what weclaim is- `vA stencil-plate having the corner of its side edge out away to facilitate connection with au adjoining plate, substantially as specified.

In testimony that we claim the foregoing we have hereunto set our hands this 6th day of March, 1876.
