STEREOTYPE-PLATE AND BLOCK OR BED FOR THE SAME.

SJ'ECIPICATION forming part of Letters Patent No. 336,022, dated February 9, 1886.

Application filed July 29, 11 85. Serial No. 172,949.

To (LZZ whom it may concern:

Be it known that I, WILLIAM THOMAS SMITH, a subject of the Queen of Great Britain, and a residentofLondon,England,have invent ed certain new and useful Improvements in Stereo typePlatcs and in Blocks or Beds for the Same,

(for which I have been granted Letters Patent of Great Britain, No. 4,321, dated October 23, 1879,) of which the following is a specification.

My invention has reference to stereotypeplates mainly for use in newspapers, which are cast or made separately from their blocks or beds upon which they rest when in the chase and locked up in the form for the purpose of being printed from. The object is to enable the stereotype-plate to be readily placed in position on the block after the latter has been placed in the form between the column-rules, leads, reglets, or furniture; and when the form has been locked up the plate will be firmly secured in position on the block, so that it cannot fall out of the form.

The operation of locking up the form also serves to draw down the plate to its block, so that it will rest snugly and firmly thereon.

I-Ieretofore it has been proposed to secure a stereotype-plate to its block or base in such a manner that it may be readily removed therefrom, and various means have been employed to effect this, notably by forming a dovetail on the plate to take into a groove in the block. This construction I do not claim, nor will it effect the object I seek to attain.

In carrying out my invention I form the surface of the block of two planes, usually parallel, and join these planes by a shoulder, which 4 the blocks after the blocks and column-rules are set in position, but before the locking of the form.

In the drawings which serve to illustrate my invention, Figure l is an edge or side view (No model.) Patented in England October 23, 1879, No. 4,321.

of a stereotype-plate constructed according to my invention. Fig. 2 is a similar new of a block to receive the plate constructed accord ing to my invention.- Fig. 3 is a similar view showing the plate and block fitted together. Fig. a is a plan of the plate. Fig. 5 is a perspective view designed to illustrate the position of the blocks in the column and illustrating a block made up of several parts. Fig. 6 is a view illustrating the mode of placing the plate on the block after the latter is set between the column-rules and before the form is locked up. Fig. 7 is the same as Fig. 3, but showing also the position of the column-rules with respect to the block and plate when the form is locked up. The column-rules prevent any lateral movement of the plate, and thus prevent it from being detached from the block. The pressure of the column-rule on the righthand side of the plate serves also to draw the plate down firmly upon the block.

a represents the stereotype-plate, the under surface of which is composed of two planes, and 1) represents the undercut shoulder which joins these two plane surfaces.

d represents the block or bed on which plate a is to be mount. (1. The upper surface of this block is composed of two planes, and o is the undercut shoulder joining these two planes.

\Vhen the plates are put together, as in Fig. 6 and as seen completed in Figs. 3 and 7, the shoulders I) and c on the plate and block engage and fit each other, and the plate rests firmly on the block.

It may sometimes be convenient to divide the block at its middle, lengthwise of the column, as indicated by the dotted line gin Figs. 2 and 3, and it may also be convenient to make up the block of several parts, as indicated in Fig. 5.

Referring to Fig. 6, it will be seen that the form may be made up of column-rules e and blocks d, and then, beforelocking up, the plates may be mounted on the blocks by presenting them to the blocks, as indicated, so as to engage the shoulders I) and c, and then pressing them down to place. By this construction and method the plates may be placed when the column-rules stand quite close to the block.

Having thus described my invention, I claim 1. As an improved article of manufacture,

' a stereotype-p1ate, (1, having an undercut retaining-shoulder, b, formed on its under side, substantially as shown, whereby it may be placed on the block after the latter has been placed between the colu Inn-rules, substantially as set forth.

2. As an improved article of manufacture, a block, d, to receive a stereotype-plate having an undercut retaining-shoulder, 0, formed on its upper face, substantially as and for the purposes set forth.

3. As an improved. article of manufacture, a stereotype-plate, a, having a single underout retaining-shoulder, b, formed on its under side, the plane of which shoulder extends crosswise of the lines of type on the face of the plate,

substantially as set forth.

4. As an improved article of manufacture, a block, d, for astereotype-plate having formed on its upper surface a single undercut retaining-shoulder,r, the pa..e of which extends lengthwise of the column, substantially as set forth.

5. The combination of the block 01, having formed on its upper side a single undercut retaining-shoulder, c, and a stereotype-plate, at,

having formed on its under side a single undercut retaining-shoulder, b, and the under side of the plate a constructed to fit and conform to the upper side of the block d, substantially as set forth.

6. As an improved article of manufacture, a stereotype-plate, at, having its under side formed of two parallel planes joined together by a shoulder, 19, which forms with said planes angles less than right angles, substantially as described, the plane of said shoulder extending crosswise of the lines of type on the face of the plate, substantially as described.

7. As an improved article of manufacture, a block, (1, for a stereotype-plate, having its upper surface formed of two parallel planes joined together by a shoulder, 0, which forms with said planes angles less than right angles, substantially as and for the purposes set forth.

In Witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
