'ADJUSTABLE 1RINTING?LATE HOLDER.

To ail whom, t may concern:

Be it known that I, EnwiN R. STORM, a citizen of the United States, residing at New York in the county of New York and State of Bew York, have invented cert-ain j move the printing-plate any small 'distanee to bring it to perfect register; third, to provide a plate to eover the grooves andprevent the printing-plate froin denting or, be- .ing foi-eed into the eroe-ves; fourth, to pro= vide al plate-clamp that will lio-ld the printing-plate and a sufficient number of andhave had their holding edges brought to beai-,on the edges of the printing-plate; fifth, to provide a means for reino-ving the plates after printing; and, sixth, to provide a means of readily removing the plateclamps from the groove. I attain these objet-ts by means of the -deviees illustrated in the accompanying drawings, in which- Figure l is a top view of a portion of a grooved block with a printing-plate and an intermediate-plate thereon and a plateclamp in position in one of the grooves, the printing-plate and the' intermediate-plate being broken away over that poi'tio-n of the plate-clamp which is secured within the groi'ire.

Fig. 3 is a top view of the base-piece showing the formed. end, the extended portion, the' hole for the set-screw and the slot in the formed end. Fig. et is an end view showing the extended portion and the threaded hole therein, also the relative eeeentrieity of the extended end to the formed end.

Fig. 14 isa modified form in which the base-piece is formed integrally with a. groove-d block that may be locked 1n 4conjunction. with other blocks in a printers chase.

Similar numbers of reference indicate corresponding parts throughout the severalv views.

The block 1, of any same 'construction as is now in common use and consists of a block having grooves 2 of greater width'at the lower than at the upperV 13 is an end view of the operating tool desired size, is ofthe part. The printing-platee? is placed upon as indicated in Fig. l: The vthin intermediate-plate Seis made a proximately the size and shape of the printing-plate. Being but slightly smaller, 4and lying immediately-upon' 'the i' dent the bottom surface of ,3 and supports the grooved block 1, it covers those parts of the grooves which lie under the printing-plate Q printlng-plate. The printingplate 3 and the intermediate-plate 3*' are held to the block 1 by the plateclamps, which consist of a base-piece 4, a se .-screw 5, an adjusting-screw 6, and a facepiece 7. The base-'piece et is formed of a thickness slightly less than the top Width of the groove 2.50 that when held with its top surface 8 perpendicular to the top surface of the block 1 it may be passed Within the groove 2, and is formed of an outline, or section, that will permit of its being rotated within` the groove and secured therein, as indicated in Fig. 5. In the base-piece 4' is formed the threaded hole 9, the slot 10, and the threaded hole 11 (shown in Figs. 1, 2, 3, 4, 5 and`7 )i.` The base-piece 4- is preferably made l with a formed end having two faces, l2 and 13, adapted to fit against the sides of the groove, as shown in Fig. 5, and a cylindrical portion 14 whose diameter is no greater than the thickness of the base-piece. (See Figs. 2, 3 and t.) v

To the threaded hole 9 is fitted the setscrew 5, whichis formed of a length that is less than either thewidth or the depth of the groove 2 and has its lowerend 15 vadapted to bear against and, lif need be, in-

the groove, as

indicated in Figs. 1"and 7. To the threaded hole 11, which is formed with its axis par? allel to but at a distance from the longitudinal axis of the basefpiece, is lit-.ted the `threaded portion L16 of the adjusting-screw 6. The adjusting-screw 6 is formed with a threaded portion 16, a cylindrical portion 6, adapted to pass within the threaded hole 11 and a head 17 in which is formed the slot 18. Between the head 17 and thecylindrieal portion 6 is formed the shoulder 19. (See Figs. 6 and 7.)

To the cylindrical portion (Bof the adjusting-screw is fitted the curved surface 20 of the'incinber 21 which is formed integrally with the face-piece 7. The member 21 is adapted to extend within the groove 2, and is vformed with a face 22 conforming with and'adapted to bear against a side of the ,said groove 2. (See Figs. 8, 9, 10 and 11.) The member 21 is recessed, forming a surface 23, adapted to. receive theshoulder 19, and a surface 24 adapted to receive the head 17, and' is ,further formed with a surface 25, tangent to the curved surface 20 and approximately parallel to the surface 22, adapted topass .the cylindrical portion of the adjusting-screw 6 when the said adjusting-screw is in the groove and the face-piece (See Figsf?, 9, 10 and 11.) In the face is -being placed in position on the block 1.

piece 7 is formed the hole 26 adapted to permit an operating-tool to engage with the vement handle,

slot 1S. On the face-piece 7 is formed a holding edge 27 adapted to bear against the inclined edge of the printing-plate 3 to hold the plate to the block l. (See Figs. 1, 7, 8, 9, 10 and 11.) y

The operating-tool 2S, fitted to any connot shown, is of ay size to lit the hole 26 and formed with a reduced portion 29, having rounded edges, adapted to `yenter the slot 18 and operate the adjusting screw 6. (See Figs. 12 and 13.)

p The manner of using the printing-plate holders is as follows: Having determined the approximate position of a printing-platc 3 upon the greovc'd block 1, the printingplate is laid to one side and the base-pieces 4 with the set-screw 5 wholly Within the threaded hole 9, that is, so neither extremity projects beyond the top or bottom surface of the base-piece, and the adjustingscrew (i held in the threaded hole 11 are entered u'ithin the grooves, preferably in the space that is to be covered by the printing-plate. 'lo enter lhebase-picec -1 within the groove 2, hold the base-piece so the slot 10 is parallel with the face of the block 1, and drop the basepiece in the groove, next, rotate the base-picce within the groove, this may be done by pressure. of the fingers moved at a right` angle to the groove, or, by inserting the end of the operating-tool 2S, or of a Screw driver, in the slot l() and, while holding the lingerlagainst thc end of the cxtended portion 11, turning the operatingtool until the slot 10 is perpendicular to the bottom surface of the groovel 2 and the head of the set-screw 5 is exposed to view. `The base-piece will then be wholly within the groove 2 and ready to be secured lo place. To secure the base-piece 4 to` the groove, rotate thc set-screw 5 until its lower extremity 15 pressing against the bottom surface of the groove 2 lifts the base-piece -l and presses the

surfaces

12 and 13 against the sides of the groove with sullicicnt force io hohl lhc base-piece immovably to the block 1, if necessary,- causing the end 15 to indent thc bottom of the groove. 2. Then the base-piece is secured within thegroove the adjustingserew is rotated until all of the c vlimglrieal portion 6 is exposed and the face-piece 7 is pnt in place on the block b v inserting the member 21 within the groove. in the space lying between the threaded end 16 and the shoulder 19\of the :uljusting-screw 6, with the surface bearing and sliding against a side of the groove and the surface 25 passing between the` same side of the groove and the cylindrical portion 6, until the surface 20 rests on the cylindrical portion'6 and the face-piece 7 rests on the top snrface of the block 1.` The face-piece 7 is then moved lelngthwise` of the groove toward the head '17 causing thc surface 24 to move along the cylindrical surface the groovev a'ld rotated therein a setscreW adapted to hold the base-piece securely to any point of the groove, an adj usting-screw engaging with the base-piece and a facepiece with :L holding edge thereon, controlled by the adjusting-screw.
