FEED-GAGE.

sive device of this character ca able of being quickly attached to or detached rom the tyman of the press and which may be adjusted aterally of the platen thereby to aline the printing sheets.

A further object of the invention is to provide a feed gage including superposed members or plates one of which is provided with a pivoted clamping lever having spaced contact points adapted to bear against the upper surface of the adjacent member thereby to clamp said members in engagement with the tympan and thus effectually prevent turning or twisting movement of the gage.

A further Objectis to arrange the sup orting ears of the clamping lever at an ang e or inclination with respect to the upper member or plate so that when the gage is positioned on the cut or slit edge of the tympan and the lever moved to closed position a clamping action will be exerted on the tympan at a point remote from said slit.

A further object is to arrange the clamping lever at right angles to the line of feed, and further to provide a spring locking li which co-acts with the clamping lever for' ocking the stripper in adjusted position.

A still further object of the invention is to generally improve this class of devices so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the'following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.-

responding parts in all of the figures of the drawings.

' The improved gage forming the subject matter of the present invention is principally designed for attachment to the tympans of platen printing presses and by way of illustration is shown ap lied to a printing press of `this type in whic 5 designates the platen bails and 6 the tympan.

The gage consists of superposed clamping members or plates 7 and 8 adapted to engage the upper and lower surface of the tympan at one of the transverse cuts or slits 9, as best shown in Fig. 1 ofthe drawings.

One edge of the lower plate 7 projects laterally beyond the adjacent longitudinal edge of the upper plate 8 and is inclined or beveled, as indicated at 9 so as to permit the beveled end of the lower plate to be inserted in the slit in the tympan with the beveled edge 9 bearing against the lower surface of the tympan.

The metal forming the lower plate 7 is slit or cut longitudinally and thence bent upwardly and rearwardly to form spacedv supporting ears 10 having their freeends provided with terminal eyes 11 for the reception of the adjacent reduced ends 12 of a clamping member 13.

The supporting ears 10 extend through openings or recesseslll formed in the upper plate 8, the metal at said opening being pressed downwardly so Aas to form closures for the openings after the ears have been eX- tended through said openings, as shown.

It will thus be seen that the slit or cut portions 15 of the upper plate not only serve to close the openings 14 but, by engagement with the ears 10 serve to assist in preventing sliding movement of one plate with relation to the other.

rlhe clamping member 13 is provided with an angular extension 16 having its central portion cut away at 17 to form spaced contact points 18 whichlbear against the adjacent surface of the upper plate 14 when the lever is moved to operative position and thus clamp the upper and lower members in engagement with the tympan.

The upper plate 8 is provided with an up- Similar numerals of reference indicate cor' struck integral spring lip 19 which is spaced from the upper surface of the plate to form a recess or socket for the reception of a tongue or stripper 20. The free end of the lip 19 extends in the path of movement of the extension 16 of the clamping lever so that When said lever is depressed the central boWed portion 17 of the extension will bear against the adjacent or free end of the lip 19 and cause the latter to engage the tongue 20 and lock the same against longitudinal movement. The upper plate 8 is also preferably formed With spaced up-struck lugs 21 disposed one on each side of the lip 19 and Which bear against and form guides for the tongue or stripper 20. It Will thus be seen that the lever 13 serves to clamp the members 7 and 8 in engagement with -the tympan and at the same time force the lip 19 in engagement With the tongue so as to lock the latter in adjusted position.

Attention is here called to the fact that the supporting ears 10 are inclined rear- Wardly at an angle to the upper face of the plate 8 so that When the gage is positioned on the slit or cut portion of the tympan and the lever moved to operative position the spaced contact points 18 of said lever will bear against the upper plate 8 at a point remote from the cut or slit 9 and thus effectually prevent twisting or turning movement of the gage on the tympan. It Will also be observed that the clamping lever 13 is arranged at right angles to the line of feed of the printing sheets so that the lever may be conveniently manipulated when it is desired to adjust the gage on the tympan.

One end of the upper late 8 is bent upon itself to form a gage-heacl)22 having its opposite ends curved laterally at 23 so as to prevent the printed sheets from catching on the head When feeding the sheets to the press,

there being an opening 24 formed in the gagehead for the reception of the tongue or stripper, as shown. v

In operation one or more of the gages are ositioned on the tympan by inserting the beveled edge 9 of the lower plate of each gage beneath the tympan at the adjacent slit 9 and adjusting the gage-head 22 laterally to the desired feed line after Which the free end of the lever 13 is depressed Which causes the contact points 18 to bear against the upper surface of the plate 8 and clamp said plate in engagement with the tympan. As the lever 13 is moved to operative position the curved or bowed portion of the extension 16 Will bear against the adjacent end of the lip 19 and clamp the latter in engagement With the tongue or stripper, in the manner before stated. In order to remove or adjust the gage it is merely necessary to elevate the free end of the lever 13 when the clamping members and tongue 19 may be released so as to permit the ready removal of the gage or further adjustment of the same.

By forming the lever 13 with spaced contact points a double gripping effect is obtained while by reason of the inclination of the supporting ears the pressure of the clamping member is exerted at a point remote from the slit edge of the tympan so as to eifectually lock the gage against lateral and longitudinal movement.

From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary.

Having thus described the invention what is claimed is:

1. A feed-gage including su perposed members one of which is provided with a locking lip and the other with spaced ears, a stripper extending beneath the lip, and a clamjiing device pivotally mounted between the ears and adapted to engage the lip and ad jacent member.
