PRINTING-PRESS GAGE.

Specification of Letters Patent.

Patented Dec. 6, 1921.

T 0 all whom it may concern Befit known that 1. EDWARD A. Conny, a citizen of the United States. and a resident of the borough of Brooklyn, county of Kings, State of New York. have invented an Improvement in Printing-Press Gages, of which the following is a specification.

My invention relates to printing press gages and more particularly to such as are adapted for use in connection with printing from an engraved or similar plate. Much difficulty has hitherto been experienced in properly adjusting the plate with respect to the gage which defines the place in which the paper or other medium to be printed upon should be positioned to receive the desired impression.

It is an object of the present invention to provide printing press gages which shall be simple in construction, and efficient in use by reason of their ready adjustability, which enables such gages to obviate the difficulty above mentioned.

By way of example I have illustrated in the accompanying drawings a preferred embodiment of my invention, in which drawings Figure 1 is a plan view of the printing press gage as attached to the table or support which is to carry the engraved plate or other impression-imparting device;

Fig. 2 is an end elevation and Fig. 3 a bottom plan view of the same;

Figs. 4 and 5 are detail views in plan and elevation, respectively, of a part of the gage;

Fig. 6 is a cross sect-ion of the same on line 6-6 of Fig. 3.

In its preferred form, described herein for purpose of illustration only, the printing press gage comprises a supporting menr her 1, preferably in the form of an angle iron having one face 2 thereof for attachment to the gage proper, herein indicated generally by the reference character 3, and the other face 4 thereof for attachment to the table, platform. or other support 5 which is designed to carry the engraved plate or other printing device 6 and the paper or other medium 7 which is intended to receive the impression from the printing device 6. Any suitable fastening means, such as the screws 8, passing through apertures in the supporting member 1 and into the table 5, may be employed to attach the supporting member 1 and the gage 3 carried thereby to the table The printing gage proper comprisesan elongated gage member 10 which is pref erably provided with a raised longitudif nally disposed guiding portion 11. Preferably, the guiding portion 11 has the inner straight edge 12 for coiiperating with the straight edge 13 of the transverse gage men ber 14. r

In order that the plate or other printing device 6, when once approximately accurately positioned on the table 5, should not need to be further disturbed in order to bring the same into proper relation to the sheet of paper 7 for the printing operation, the gage 3 is designed to be capable of angular and transverse adjustment relatively to the supporting member 1. For this purpose face 2 of member 1 is provided with a plurality of slots 15. Member 10 is in turn provided with a plurality of apertures 16 for receiving the headed screw. bolts 17, the inner ends of bolts 17 being provided with nuts 18 to maintain member 10 in its angularly and transversely adjusted position relatively to supporting member 1.

The transverse gage member 1 1 is slotted as at 19. Preferably slot 19 is of a size to include a plurality, as two, of the threaded apertures 20 with which member 10 is provided. The threaded apertures 20 are successively spaced apart a distance correspond ing to the difference in size of successive standard sizes of the medium, aspapei', to be printed upon;

Transverse gage member 14: is provided with the transverse, raised guiding portion 21 cooperating with the raised portion 11 of member 10 to define an angle 22, which is a right angle, for receiving one corner of the paper '7 which is to receive the impression from the plate 6. Passing through slot 19 is an adjusting member 23 comprising a knurled knob 24 and a threaded member 25 which is designed to pass through slot 19 and selectively into any desired one of the threaded apertures 20.

The manner of using the printing press gage herein shown and described by way of example, will be substantially clear from the foregoing description. After plate 6 has been applied to the table or other support 5 with approximate accuracy, the elongated gage member 10 is adjusted angularly and transversely with respect to plate 6 by operation of nuts 18 at the end of the threaded bolts 17 the desired freedom of angular and transverse adjustment being provided by the provision of slots 15. This will bring the raised guiding portion 11 of member 10 into parallelism with the lines of engraving on the plated Longitudinal adjustment of the gage 3 with respect to the plate 6 is provided by means of the transverse gage member 14. For this purpose the adjusting member 23 is passed through the slot 19 of the member 14 and into any desired one of the apertures 20. Since, as is preferred, slot 19 is of sufiicient extent to include at least two of the apertures 20, any adjustment between two successive apertures 20 may be effected. Preferably, as shown, member 14 is of a springy material and is slightly bowed out,

as shown at 14:, to enable adjusting member 23 to more readily and conveniently hold member 14 in its adjusted position.

When the desired adjusted position has been attained, member 23 is screwed home,

thereby maintaining the gage 3 in its de sired position. The straight edge '13 of member 14 cooperates with the straight edge 12 of the member 10, facilitating the maintenance of an accurate right angle at 22. For this purpose member 14, slot 19, parts 10 and 11, and apertures 20, are so arranged and proportioned that member 1 1 will fit snugly against raised portion 11 of member 10.

The printing mechanism, not being a part of the present invention, is not here shown, although it is, of course, to be understood that any desired type or construction of printing and inking mechanism may be employed. a

It is also to be understood that my invention is not to be limited to the specific embodiment thereof herein shown and described for purposes of illustration only.

What I claim is: 1. A printing press gage comprising, in

combination, a supporting member, an elon gated gage member of angular] cross-section, having a raised, longitudinally disposed guiding portion, means for attaching said elongated gage member to said supporting member, a slotted transverse gage member associated with said elongated gage member and adjustable longitudinally thereof, said transverse gage member having a raised portion cooperating with the raised portion of said elongated gage member and said elongated gage member having a plurality of threaded apertures therein, and a threaded adjusting member passing through the slot in the transverse gage member and selectively into any desired one of said threaded apertures to maintain said transverse gage member in its adjusted position relatively to said elongated gage member.

2. A printing press gage comprising, in combination, a supporting member, an elongated gage member having a raised longitudinally disposed guiding portion, means for attaching said elongated gage member to said supporting member so as to permit relative angular adjustment of said members, a slotted transversegage member associated with said elongated gage member and adjustable longitudinally thereof, said transverse gage member having a raised portion cooperating with the raised portion of said elongated gage member and said elongated gage member having a plurality of threaded apertures therein, and a threaded adjusting member passing through the slot. in the transverse gage member and selectively-into any desired one of said threaded apertures, to maintain said transverse gage member in its adjusted position relatively to said elongated gage member. 7 j

In testimony whereof, I have signedlny name to this specification this 7th day of August, 1918.
