Application February 12, 1954, Serial No. 409,946
3 Claims. (Cl. 153-48)- This invention relates to an instrument for straightening bent lugs of a type casting matrix and has for its primary object to salvage matrix of the type employed in type casting machines of the type. commonly known in the art as linotype machines.
In the operation of machines of the type above referred to, matrices which are employed for molding the type faces on a slug are provided with guide lugs which project outwardly from opposite sides thereof adjacent opposite ends thereof. In the course of the operation of the ma chine, these lugs frequently become bent and as a consequence the matrix becomes unserviceable and heretofore it has been customary to discard matrices having bent lugs.
As above stated, the primary object of this invention is to salvage the matrices. having bent lugs and to restore them to serviceability with but a minimum of effort.
Another object is to effect economies in the operation and maintenance of type-setting machines of the type above referred to.
The above and other objects may be attained by employing this invention which embodies among its features a bed having a recess opening through one face thereof for receiving the body of a matrix, lug engaging and supporting anvils carried by the bed and extending outwardly therefrom adjacent opposite longitudinal side edges thereof, and a pressure plate carried by the bed for engaging the matrix and advancing it toward the bed and the lugs toward the anvils to straighten the lugs relative to the matrix.
Other features include a wedge plate carried by the bed in spaced relation to the anvils, a wedge extending between the anvils and the wedge plate for engaging a matrix, the lugs of which rest on the anvils, a boss carried by the wedge and extending outwardly therefrom adjacent the thicker end thereof for advancing the wedge into the space between the anvils and the wedge plate to force the wedge against the lugs of a matrix disposed in the recess in the bed, the wedge plate having a channel opening through the face thereof adjacent the bed and also opening through the thicker end of the wedge plate, and a second boss carried by the wedge and extending longitudinally outwardly therefrom adjacent the thinner end thereof and through the channel for moving the wedge plate out of wedging engagement with a matrix mounted in the recess in the bed.

Figure 6 is a perspective view of a modified form of the invention;
Figure 7 is an enlarged longitudinal sectional view taken substantially on the line 77 of Figure 6;
Figure 8 is a transverse sectional view taken substantially on the line 8-8 of Figure 6; and
Figure 9 is an exploded perspective view of the modified form of the invention.
Referring to the drawings in detail, a bed 10 is provided with a longitudinally extending recess 12 defining adjacent opposite side edges of the bed anvils 14 upon which are supported lugs L of a matrix M, the body of which is disposed within the recess 12. Secured to opposite sides of the bed 10 and extending perpendicularly outwardly from the side thereof having the recess 12 therein are supporting plates 16.
Secured to the side plates 16 in spaced relation to the bed 10 is a wedge plate 18 having an inclined face 20 disposed toward the bed 10, as will be readily understood upon reference to the drawings. The recess 12 in the bed 10 terminates short of one end thereof to define a stop 22 and in assembling the wedge plate 18 with relation to the bed 10, the thicker end of the wedge plate is disposed adjacent the end of the bed adjacent the stop 22. Formed in the wedge plate18 and opening through the thicker end thereof and the inclined face 20 is a longitudinal groove 24, the purpose of which will hereinafter appear.
A wedge 26 having an inclined face 28-, the angle of which coincides with the angle of the inclined face 20 of the wedge plate 18 is adapted to be entered into the space between the wedge plate 18 and the bed 10 and carried at the thicker end of the wedge 26 and projecting longitudinally therefrom is a boss 30 which is adapted to be struck by a hammer or the like to advance the wedge into the space between the bed 10 and the wedge 18 to cause the under-surface 32 of the wedge to impinge upon the upper face of a matrix M and lugs L to cause the upper faces of the lugs to lie in the same plane as the upper face of the matrix M. A boss 34 is carried by the wedge 26 and projects longitudinally from the thinner end thereof and through the groove 24 to provide a striking surface which may be engaged by a hammer to drive the wedge out of the space between the bed 10 and the wedge plate 18 to enable the wedge to be removed and the restored matrix to be extracted from the recess 12 in the bed 10.
In the modified form of the invention illustrated in Figures 6 through 9, inclusive, a bed plate 36 is provided with a longitudinally extending recess 38 which cooperates with opposite side edges of the bed plate 36 to define anvils 40 which extend longitudinally of the bed plate 36 adjacent opposite sides thereof and are adapted to engage lugs 1 carried by and extending outwardly from opposite sides of a conventional matrix m. Carried by and projecting outwardly from the bed 36 adjacent opposite ends thereof and substantially midway between opposite anvils 40 are guide pins 42 which are adapted to project through guide openings 44 formed in a pressure plate 46 which, as illustrated in the drawings, is adapted to engage the sides of the lugs 1 remote from the anvils 40. In order to advance the pressure plate 46 toward the bed 36 to straighten the lugs 1 resting on the anvils 40, the pressure plate 46 is struck a sharp blow by a hammer to drive it along the guide pins 42 toward the bed plate 36 and against the matrix m.
Obviously, the wedge 26 constitutes a pressure plate which is advanced toward the anvils 14 of the bed 10 to cooperate with the anvils in straightening the lugs L of the matrix M.
From the foregoing, it is obvious that a simple inexpensive instrument is provided which is capable of easily and quickly straightening the lugs of matrices so as to restore 3 the matrices to serviceable condition and eflfect the salvage thereof.
While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
