MATRIX FOR LINOTYPE 1111101111113. I APPLICATION FILED APB..19,. 1909.
Pathted Apr. 11, 1911.
HEINRICH DEGENER, OF BERLIN, GERMANY.
MATRIX FOR LIN'OTYPE-MACHINES.
Specification of Letters Patent.
Application filed April 19, 1909. Serial No. 490,747.
To all whom it may concern:
Be it known that I, HEINRICH Dnonnnn, v
- above arrangement has the disadvantage that the matrix sliding down, damages the working ledges provided at both sides to insure a close engagement of the matrices, and more particularly spoils or destroys the fine lateral walls of the character or type on the printing face of the matrix. In order to obviate the above disadvantage, it has already been attempted to provide the matrices in the center of their foot surface with projections to engage with the matrix which is in front of them in the line. This arrangement cannot, however, be used without altering different parts of the mechanism of the machine, owing to the change in the shape of the matrix.
This invention relates to a matrix in which, without altering its outer shape, the matrix placed into line, engages the central portion of the lateral surface of the preceding matrix, only with the central portion of its lower surface.
The drawings show two constructions according to this invention, Figures 1 and 2 being side elevations of two such matrices, while Fig. 3 shows how the matrix adjoins the preceding one and slides along the same. Fig. 4: shows a matrix with the recesses slightly wider than the packing ledges.
The matrix is generally made like a wellknown ordinary matrix but differs from the same by recesses made in its foot. These recesses a in Fig. 2 have the shape of grooves.
The width of the grooves is that of the packing ledges b of the. matrices, so that when the matrix slides along the preceding one a striking of the two matrices against each other is avoided, exactly at the point where are situated the packing ledges b, and they come into contact only in the center as shown in Fig. 3. The arrangement of the recess in the form of a through groove has the further advantage that in any desired position of the matrix sliding down, that is to say, even when it is coming into contact with the preceding matrix in an almost horizontal position, no contact of the above mentioned packing ledges takes place.
In many cases, more particularly when the matrices do not slide down in an excessively oblique position, it may be sufficient to make the recesses not as a throu h groove, but as shown in Fig. 1 to reduce tie thickness of the foot of the packing ledges in the same manner as the lu s c are reduced. If the recesses have only the same width as the workin ledges, it happens that the matrix falling down in spite of its recesses strikes against the said ledges, because by any accident during the sliding down the matrix can be laterally shifted a little. In order to prevent this disadvantage the recesses can be made slightly wider than the width of the packing ledges. This construction is disclosed in Fig. 4 of the drawing, in which the grooves a are shown as being slightly wider than the packing ledges b.
As said above the bottom of the matrix according to this invention does not alter its outer shape excepting in the recesses 64; it means the bottom of the matrix body is flush with the bottom of the lower matrix ugs.
Having thus fully described the nature of my invention, what I desire to secure by patent is:
1. A linotype matrix having the middle portion of the side faces reduced in thickness from top to bottom, being provided with contact faces consisting of two parallel packing ledges and having lugs, the bottom of the matrix body being flush with the bottom of the lower lugs and being provided with two recesses below the said packing ledges, substantially as described.
2. A linotype matrix having the middle portion of the side faces reduced in thickness from top to bottom, being provided with contact faces consisting of two parallel packing ledges and having lugs, the bottom of the matrix body bein flush with the bottom of the lower lugs and being provided with two recesses below the said packing ledges, said recesses being made in form of grooves.
3. A linotype matrix having the middle portion of the side faces reduced in thickness from top to bottom and having contact faces consisting of two parallel packing Patented Apr. 11, 1911.
ledges and also having at the bottom two I In witness whereof I have hereunder set recesses substantially as described to prevent 1 my hand in presence of two witnesses. its contact with the packing ledges of a preceding matrix when descending to the HEINRICH DEGENER' end of line, said recesses being made in form Witnesses: of grooves and being slightly wider than WOLDEMAR HAUPT,
the packing ledges. HENRY HAsPER.
