Specification of Letters Iatent. Patented Aug, 21, 1517.
Original application filed July 16, 1909, Serial No. 507,934. Divided and this application filed November 18,
' 1913, Serial No. 801,574. Renewed January 22, 1917. Serial No. 143,855.
To all whom it may concern:
Be it known that I, HENRY A. WISE WooD, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Method of Making Stereotype- Matrices, of which the following is a specification. I This is a division of my patent on a method of making stereotype matrices filed July '16, 1909 ,-and patented Feb. 2, 1915, No. 1,127,340. g
The objects of this invention are in general the same as those set forth in the above named patent, but this patent relates to one specific way' of. carrying, out the idea, in which there is no second molding operation and consequently no chance of distorting the matrix even if it should become too dry. In fact-this specific method can be applied to matrices intended-to be leveled by molding, if they are accidentally allowed to dry too much. In some cases also this method can be made more exact than the double molding species of this invention.- Further objects and advantages ofthe invention will appear hereinafter.
Reference is to be had to the accompanyigure 1 is a transverse sectional view showing the firstistep in the production of a matrix according to this method;
Fig. 2 is a similar view showing the fin- I ishing operation;
Fig. 3 is a similar fication; v
Fig. 4 is a similar view showing a slight modification, and
Fig. 5 is a plan of part of Fig. 4 on a small scale.
Although Fig. 1 illustrates the firstlstep of the preferred way of carrying out this improved method, yet it also ent way of molding stereotype matrices. In this figure is shownthe usual chase 10, typev 11, felt molding blanket 12, platen 13, and flong 14 which is being molded into the form of a matrix. As the felt or other molding view showing a modiblanket is soft and elastic the small characters as for example, periods, commas, is, ls, ts, etc., may be considered to force themselves more deeply into the flong than the wide characters, as for example w s, ms, and
employed for the purpose of skiving down shows the prescapital letters. Thus the fiong is pushed down farther on the small characters and the matrix will be left thinner over their tops, as for example, where it protrudes at the points 15. But over the large characters a comparatively thick body of fiong will be left to form protrusions 16. Thus while the plane of all the characters may be the same upon the face of the matrix when it is removed from the type the matrix will be of varying thickn ass at the back of the letter impressions. Therefore, when the matrix is put into the casting box and the metal introduced the pressure of the latter will tend to force the back -of the matrix firmly against the surface of the box which is a uniform plane or semi-cylinder, and thus the surface of the various cast letters will appear in planes of different heights.
In order to avoid this diificulty according to the form of the present method shown in Figs. 1 and 2, the matrix is molded in the usual way by the use of a platen, roller, or other pressing means. Then the blanket is removed and the flong is dried on the type 11. c
Then the type and dry flong are passed under a roller 27 having an abrading sur. 1 face. It is'rotated at a diife'rent speed or in a difierent direction from the direction of travel of the surface of the matrix. It may be stated also that in this case the disk 25 as shown in Figs. 4 and 5 may be used having an abrading lower surface. As a substitute for the latter methods, or in addition thereto a long straight knife 28 may be the back ofthe matrix to a uniform thickness when the matrix is dried, and before or after it is removed from the type, as shown in Fig. 3. It will be seen that as the matrix is dried before the leveling operation, it has come to its final shape and ordinarily-cannot warp or become distorted after itis leveled so that a matrix is produced'which'is accurate and has a firm uniform bearing surface on the back that will not readily become distorted in use. As all the matrices will be of the same thickness, the casts produced will be of a uniform thickness. v 1?.
It will be understood that the invention can be carried out in many otherways'without departing from the scope of the invention as expressed in the claims. Therefore,
I do not wish to be limited to the precise 7 step shown and described, but what I do 5 claim is 1. A method of making stereotype matrices which consists in molding the flon drying it to harden it and cause it to ho d the shape in which it was molded, and re- 10 moving the rear surface thereof until it is reduced to a uniform plane above the sure faces from which it was molded.
2. A method of makin stereotype matrices which consists in mo ding the flong on typeunder a soft blanket whereby an uneven back is provided, drying it while still on the type, and leveling the rear surface by abrasion thereof while the dried fiong is supported on the type on which it was molded. a
In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
