V o I Among the objects of the invention is to' facilitate the placement of the sheet gauges on the platen, with respectito the form or stencil in printing machines, 7
Another object is to combine a paper gripagainst shifting during the printing, embossing and stamping ioperationio Other objects and advantages will 'appear as thejdescription progresses.
A further objectis to provide a combined sheet gauge and gripper which may be "de-o pressed below the plane of the platen.
' "In'this specification and'the accompanyingdrawing, the invention is disclosed in its preferred form. But it is to be understood that it is not limited to this form because it may be embodied-in other forms. It'is also to be understood that in and by the claims following the description it. is desired to cover the invention in whatsoever form 'it may be embodied. or I Broadly'stated, the invention consists in combining the sheet gauges and depressible V sheet grippers ina plate which may be ad-' justablyattached to the platen or bed of the printing machine. In the one sheet of drawing: I I

not to injure the same or interfere with its. impression. In the present instance the gauges 6 mounted upon the spring wire stems 8 depress into the throats 2 if so located that they come within the margin of the form or stencil. This is particularly valuable in the latter case, since the stencil being of fragile silk cloth, suchas bolting cloth, would be injured. or' the impression marred if the guide did not give way under pressure.
In the economical use of the stencilit is often desirable to distribute several jObs or impressions throughout. the area 'of the This is possible bythe use-of this invention openings having grippers thereon coacting with the edge of said openings.

upper surface of the heads 6 should be slightly' convex to protect the stencil.
' The number of gauges used in either or both series will depend upon the size of the sheet 13 or the amount of gripping necessary to prevent it from shifting. 1
