,I MPROVEMENTIN DEVICES FOR'CHANGING HEADS IN NEWSPAPERS.

Specification forming part of Letters Patent No. 159,172, dated January 25, 1875; application filedv October 22, 1874.

To all whom it may concern:

Be it known that I, PATRICK Fousrrn, of Cincinnati, Hamilton county, hi0, have invented a new and useful Device for Changing Headsin L'ewspapers, of which the follow-. ing is a specification:

The invention relates to a device to facilitate the removal, replacement, or substitution of any desired portion of acolumn in the form from which a newspaper is printed-such,forexample, as heads and sub-heads of advertisements.

My contrivance consists, essentially, of a bed, block, or body, having on its working face an interrupted dovetail groove or channel, into which a correspondingly-dovetailed shallow electrotype may be inserted, or from which it may be withdrawn without inother side of the margin. My contrivance further comprises a-self-closing catch, whereby the said separable type is firmly locked 1n position for printing, said catch being readilyreleascd for withdrawal of the type, as above, by means ofa point or stylus iu the hands of the printer.

In the accompanyingdrawing, Figure 1 is a perspective view, representing one of my bed-blocks in position, and ready for the reception of'the electrotype-plate, which is shown detached. 2 is a plan representing the same parts, with the plate partially inserted, a portion of the neighboring column of the adjacent page being represented. Fig. 3 shows the plate locked in position on the bed. Fig. 4 is a longitudinal section through the plate and bed. Fig. 5 is an under-side perspective view of my bed. Fig. 6 shows a bed and corresponding plate with four interruptions in place of one, as in the preceding figures. I

The outer surface a ofmy bed A is depressed as much below the general faceof the matter as the depth of the electrotype 13. Rising from said surface a, parallel with the lines-of matter, are two series of inter-. rupted curbs or flanges, U o O c, which fit and embrace corresponding dovetail projections 1) (11) d from the upper and lower edges of the type.

()ne interruption is here shown for each flange; but, for a narrow margin, withdraw al-of the plate, without interference with the neighboring column, may be secured by a greater number of interruptions with correter is left at liberty. An upward project-ion,

H, from the catch att'ords a convenient surface for the nnpact ot'a point or stylus, whereby the catch may be depressed so as to enable the withdrawalor insertion of the plate by the compositor.

I represents the separating-rule of the coutiguous column of type, and J a portion of the chase.

M y device may be formed to withdraw either to right, as shown, or, by reversing the parts, to the left, for use in the opposing page; or the same-block may be effective, in the respective positions, by simp'e reversion.

The common margin or interval between two adjacent pages of a newspaper is not com monly as great as the width of a column, and hence the necessity of a mode such as described ofso fastening theplate as that it can be separated, by an endwise movement, considerablyless than the width of a column.

set my hand.
