9 Claims.

The present invention relates to jigs, and particularly to a jig for reconditioning the damaged lugs of matrices as used in typesetting machines.

Matrices are provided at one end with projecting lugs, one on the casting face side, known as the casting face lug, and one on the reading face side known as the reading face lug. On the casting face side of the matrix, the top edge of the lug is the aligning edge for the matrix, the bottom edge performing no function in the aligning operation. On the reading face side of the matrix, the bottom edge of the lug is the aligning point for the matrix, the top edge performing no function in the aligning operation. These 3 aligning edges of the lugs of matrices become damaged, caused by an operator of a typesetting machine forcing down what is known as a tight line, or to faulty adjustment of one of the elevators in the machine. When the lugs become damaged, the matrices are of no further use, for

the reason that the damaged lugs cause the indicia on the matrices to be cast offset and out of alignment in the cast line, and consequently certain letters or numerals would be offset in a printed line.

It is therefore an object of the present invention to provide a jig with means, whereby the damaged aligning edges of the lugs of matrices may be reconditioned and restored to their original condition.

Another object of the present invention is the provision of a jig adapted for use, either by a right handed or left handed operator in the reconditioning operation.

A still further object of the present invention is the provision of a jig, portions of which may be used as an anvil to straighten and flatten the lugs if they become bent or burred during the reconditioning operation.

A still further object of the present invention is the provision of a jig equipped with tool receiving means, i. e., parts of the jig to be used as a filing gauge to restore lugs, after being reconditioned, to the exact size of the original matrix, both in width and height of the aligning lugs.

A still further object of the present invention is the provision of means for holding matrices in the jig during the reconditioning operation.

P A still further object of the present invention is the provision of a jig, means in the jig for receiving matrices, and means for realigning the lugs of matrices.

A still further object of the present invention 55 is the provision of a gauge means for reconditioned matrices, to determine the width, height of and distance between aligning lugs of repaired matrices.

A still further object of the present invention is the provision of a jig provided with means for receiving matrices of all sizes.

Other objects of the present invention will be more fully understood from the following description and claims when the same are read in connection with the drawings accompanying and forming part of this specification in which:

Referring to the drawings, the numeral 2! represents my novel jig of any suitable material and by preference case hardened steel, having a face A, a face B and walls D, E, F, and G. The face A of the jig has a longitudinal rabetted portion 22, a stud or block portion, 23 and studs 24 and 25, the stud 24 being of substantially oblong configuration and having its end wall 26 spaced from the end wall 21 of the stud or block 23, the opposite end wall 28 of the stud 24 having a. cut out portion of substantially L-shaped configuration for a purpose to be later described. The stud is of a smaller oblong configuration than the stud 24 and has one end wall 29 spaced from the wall 21 of the block or stud 23, and it is to be further noted that the end wall 29 is not uniplanar with the end wall 26. From the wall 2"! of block 23 to wall F the length is of a predeter mined one. The inner wall 30 of stud 25 is spaced from the inner wall 3| of the stud 24 a predetermined distance, the walls forming a channel way or slot 32. A transverse slot or channel way 33 is formed in the face A as illustrated in Figure 1 of the drawings, the slot or channel way being in communication with the slot or channel way 32, the channels or slots forming a T-shape configuration, the slot or channel way 32 being marked with the letter C indicating the casting face of the jig. The top faces of the stud or block 23 and studs 24 and 25 are in the same fiat plane. The longitudinal wall 34 of block 23 and the longitudinal wall 35 of stud 24 are uniplanar.

As illustrated in, Figure 1 of the drawings, the wall E of the jig has a transverse cut out portion 36 that forms a slot 31 having an inclined or beveled wall 38, a portion of the wall E serving as an anvil.

The wall F has a cut out portion 39, a portion 40 of which is of L-shape configuration, and it is continuous with the L-shape configuration in the wall 28 of the stud 24, the remaining portion in the cut 39 having an inclined wall 4|.

The face B of the jig has a longitudinal rabbeted portion 42 similar to the rabbeted portion 22 in the face A and it is to be noted the rabbeted portion 42 is diagonally opposite to the rabbeted portion 22. The face B is also provided with a stud or block 43, and, studs 44 and 45, the stud 44 being of oblong configuration and having its end wall 46 spaced from the end wall 47 of the stud or block 43 a predetermined distance, the opposite end wall 48 being offset from the wall D a predetermined distance. The stud is of a smaller oblong configuration than the stud 44 and has one end 49 spaced from the wall 47 of the block or stud 43. the opposite end wall 50 being offset from Wall D. The walls 46 and 49 are uniplanar, and these walls and wall 41 form a transverse slot 5| for a purpose to be later described. The end walls 48 and 50 are also uniplanar. The inner wall 52 of stud 45 is spaced from the inner wall 53 of stud 44 a predetermined distance and these walls form a channel way or slot 54, the channel way or slot 54 being in communication with the transverse slot 5!, the channels forming a T-shaped configuration. The top faces of the stud or block 43 and studs 44 and 45 are in the same fiat plane.

As illustrated in Figure 2 of the drawings, wall G has a transverse slot 55 that is in communication with the channel or slot 32, the wall portion 56 serving as an anvil.

In Figure 15 I have illustrated a new matrix showing the configuration of the casting face lug 58 and the reading face lug 59, and in Figure 16 I have illustrated the matrix 51 showing the sheared or damaged aligning edge 60 of the casting face lug and the sheared aligning edge 6! of the reading face lug.

In the use of my novel jig, to recondition the aligning edge of the casting face lug of the matrix, the jig is locked in a vise 62, the face A of the jig facing the operator. The matrix 5'! is positioned in the jig as illustrated in Figure 8 of the drawings, the matrix 51 being held in the jig by the thumb and fingers (not shown) of the left hand of the operator or by the clamp 63 illustrated in Figure 6 and in the assembly in Figure 13. From Figure 8 of the drawings, it can be seen, that the matrix 5'! fits snugly into the channel or slot 32, J

the top edge 6'! of the reading face lug impinging the end wall or lip 68 of the stud 24. The bottom edge 69 of the casting face lug is hammered by the hammer 10, held in the right hand of the operator, and as illustrated in Figure 8, the hammer is held at an angle to the lug, the lug being hammered until the aligning edge 60 is at right angles to the longitudinal casting face edge H of the matrix. When the aligning edge is at right angles to the casting face edge, the matrix is reversed in the jig as illustrated in Figure 9 of the drawings. If the aligning edge 60 of the matrix is not uniplanar with the wall 12 of the transverse slot 55 a file (not shown) is inserted into the slot and the edge of the matrix filed until it is uniplanar with the wall 12, the file is also run over the side wall G of the jig to make the side edge 13 of the lug uniplanar with the side Wall G.

Where the casting face lug of an extra heavy or thick matrix has to be reconditioned, I have [6 provided a means for the operation in the wall F of the jig as illustrated in Figures. 10 and 20. The matrix is positioned in the casting face slot 32 of the jig and the jig then clamped in the vise 62 as illustrated in Figure 10, the beveled portion 4| and the cut out portion 38 permits the hammer to be used to hammer the aligning edge of the lug in the same manner as described for the operation in Figure 8, except, that instead of the aligning edge of the casting face lug being hammered to the lip 66 it is hammered to the lip 68 of the stud 24 until it is flush with the lip 68, and at right angles to the longitudinal casting face edge of the matrix. The jig is then released from the vise and positioned as shown in Figure 9, the matrix being positioned in the casting face slot of the jig as shown in Figure 9, and if the aligning edge of the matrix is not uniplanar with the adjacent wall 12 of the transverse slot 55, the edge is filed until it is uniplanar with the wall, the file is also run over the side wall G of the jig to make the side edge of the lug uniplanar with the side wall. The jig as illustrated in Figures 8 and 10 is adapted for a left or right handed operator.

In the reconditioning of the aligning edge of the reading face lug by a right handed person, the jig is positioned in the vise as illustrated in Figure 11, the casting face A of the jig facing the operator, the matrix being positioned in the reading face slot 54 and held therein by the clamp 63 as illustrated in Figure 13 of the drawings. The swedge tool 13 having a rounded nose portion 14 is held in the position as indicated in the assembly Figure 13 and the end 15 of the tool hammered with the hammer 10 until the aligning edge 6| of the reading face lug is flush or parallel with the wall 4'! of the stud or block 43 and uniplanar with the bottom edge 16 of the matrix. The matrix is then reversed in the slot 54, with the reading face lug up and a file run over the wall E, the side edge of the reading face lug being made uniplanar with the wall E and the file run over wall D to make the bottom edge of the matrix uniplanar with the wall D.

In the reconditioning of the aligning edge 6| of the reading face lug 59 by a left handed operator, the jig 2| is secured in the vise 62 with the reading face B facing the operator as illustrated in Figure 12. The matrix 51 is held in the slot 54 by the spring 63 as illustrated in the assembly, Figure 13. The swedge tool 13 is held in the right hand and the end 15 hammered with the hammer 10 until the aligning edge Bl of the reading face lug is flush or parallel with the wall 4! of the stud or block 43 and uniplanar with the bottom edge 14 of the matrix. The operation for filing the side edge of the lug and the bottom edge of the matrix is the same as for a right handed operator.

After the aligning edges of the casting face and reading face lugs of the matrix have been reconditioned, the matrix is then ready to be tested for size, and for the sizing tests I have provided a gauge 11 illustrated in Figure 7, the gauge being provided with two openings and a shoulder. The opening 18 stamped on the gauge with the numeral I is for measuring from the top to bottom on the reading edge side of the matrix, the bottom edge SI of the lug being the aligning edge of the lug, and this side of the matrix must fit tight in the opening 18. After testing the reading face side, the shoulder 19 stamped with the numeral 2 on the gauge is applied to the casting face side of the matrix to test for distance between the bottom edge 80 of the top lug and the aligning edge of the casting face lug, and the shoulder must fit tight between the lugs. The opening 8| stamped on the gauge by the numeral lfl/is measuring the bottom width of the matrix, e side edges of the casting face lug'and the reading face lug must be uniplanar with the top companion lugs of the matrix, the bottom width of the matrix being identical with the top width, the transverse bottom portion of the matrix must fit tight in the opening 8|.
