, 8 Claims.

This invention relates to improvements in -regis-- .ter gauges for registering a sheet of paper on the platen of a printing press by accurately pofsitioningithef. sheets. that have been misplaced,

:usually asa result of feeding thesheets by hand,A

and one of the objects of. the invention is to provide an improved, simple and eiiective device of this character-Which maybe-readily attached to the .gripper finger and so positioned as vto contact the surface of the sheet and automatically move .the sheet.. edgewise upon the plateny and .into engagement with a stop pin or device during the relative movement, of the platen and gripper finger. s

A further Objectis to providean improved de-I vice of thisJ character which -may bereadily adiusted to,anypositionv.lengthwise of the linger ,and which will be irictionally held in position with relation to the fingerwithout the use of .other ,fastening means. Y.

e, A further object is to: provide an improved .device of this, character which will also cooperate with the grippernger for assisting in holding the sheet in position.

A -further object is to provide .an improved -register gauge of this character ,which periects `the aliningorK register of the sheets without. in- Vterferingwith the gripper fingers or the operation thereof.`

Io,thev attainment of theseends and the accomplishment of other,v new and useful objects as Vwill appear, the invention consists in the features Aof novelty in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described and .claimed and showninlthe accompanying drawing illustrating this invention and in which-.-

vFigure 5 is a detail perspective view of the other member of the registering gauge.

` Referringfmorefparticularly to the drawing,

the numeral I, @designates generally the platen of a printing press which is mounted to oscillate in the usual manner, and II designates the gripper bar upon which the lingers I2 are adjustably mounted and the bar II and platen Ii) are oscillated' in the ordinary well known manner.v l

The registering device is adapted to be applied to either of the lingers I2 and comprises v-essentially a body portion I3 which is of a substantially U-shaped configuration; a portion of the body being removed and the remaining portions being bent-back upon itseil, as at I,. to form spaced portions that cooperate with vthe body so that when the body is applied to the gripper finger I2 it will frictionally bind upon the finger and be held in proper position.

If desired, and in order to increase the viriction, the free ends of the portions HI may be deflected laterally, as at I5, as shown more clearly in lFigures 2 and 4.

Projecting from the body i3 is an arm or eX- tension kI6 which may be of any desired size and length and is preferably disposed between the bent back portions I4 of the body. This arm I6 may if desired, be provided with a slot I'I for lightness and for the purpose of imparting a degree of lateral resiliency to the arm.

Cooperating with the arm lo is a sheet engaging member which preferably comprises a body portion I8 having aportion of its lateral edges bent back upon itself, as at I9to forma housing or base which is adapted to be sleeved upon the arm IS and to be frictionally held in position upon the arm by the lateral resiliency of such arm.

One end of the body It projects for a considerable distance beyond the bent backeportions I9 and is preferably formed into a loop 2li one end of which loop is shaped to form a member ZI which is of any desiredlength and configuration and is resilient with respect to the body portion I8. l l

The sheet engaging member is placed upon the arm I6 and the arm is then mounted upon the finger I2 by telescoping the base VII--III with the nger, and the device may be adjusted to any position lengthwise of the inger I2. l

Similarly the sheet engagingmember may be adjusted to any position lengthwise of the arm 'I S and in a plane transverse to the `plane oi"v the longitudinal dimension of the finger I2. 4With this construction it will be manifest that lthe device may be positioned at any point lengthposition transverse to the finger I2 so as to position the same according to the point at which it is desired that the free end of the member 2| shall engage the sheet 22.

When the gauge is in position upon the finger I2 it is disposed in the space between the finger and the platen, that is, it projects beneath the finger I2 and the resiliency of the member 2| tends to move the member 2| away from the finger I2 and in a direction toward the platen l0.

In operation when the fingers |2 are moved away from the platen to permit the feeding of the sheets, a sheet is placed upon the vplaten I in the usual manner until it contacts with the usual pins or stops 23. As the space between the finger l2 and the face of the platen lil decreases during the operation of the press, the end of the member 2| will engage the sheet 22 as shown in Figure 2. As this space decreases, the member 2| will be pressed toward the finger I2 and in so doing, more of the surface of the member 2| will contact with the sheet 22, with the result that as this space decreases, the member 2| which engages only the outer face of the sheet. will move the sheet edgewise upon the platen IB until one of the edges of the sheet contacts the stops or pins 24. This will assure a proper alinement or register of the sheet.

As the space between the nger i2 and the platen I0 increases after the printing operation, should there be any tendency of the member 2| to move the sheet 22 edgewise and away from the stop 24, this will be no objection as the printing operation will then have been completed.

In order to facilitate the movement of the sheet 22 by the member 2| there may beprovided an element 25 of any suitable abrasive or roughened material, such as emery paper, sandpaper or the like, which is secured to the face of the member 2| in any desired or suitable manner, such as by means of an adhesive.

In Figure 6 there is shown a modified form of a portion of the member 2| and in this form of f the invention in lieu of the roughened element 25 which is separated from the member 2| and secured thereto, the sheet engaging portion of the member 2| may be corrugated, serrated or roughened as at 26, in any other suitable manner.

The member 2| is of comparatively thin material so that it will not interfere with the gr-ipping operation of the fingers I2 and it cooperates with the finger I2 in assisting and holding-the sheet in position.

With this improved construction it will be manifest that the same registering dev-ice may be applied to either of the ngers of the press by simply vreversing the position ofthe device with respect to the finger.

-It will also be manifest that the registering device engages the surface rof the sheet Aand the sheet ismoved by such contact and by reasonof the 'fact that the registering device does not move the sheet by engaging one of the edges thereof the possibility of ythe 'sheet buckling or of the registering device mutilatlng the edge of the sheet will be obviated.

While the preferred forms of the invention have been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts,

within the scope of the claims, without departing from the spirit of this invention.
