'le is e entnre olf this invenion that the :mis 40 about which the inge lnrns is inn in llie The 'posh laitier in the saune manner y ment of the platen about the axis 17 causes a takes place. sidewise or transversely on the p aten be# relative transverse movement between the gage and the laten. The extent of this movement is indicated by the distance marked 50 in Fig. 6. 5

The arm 35 carries a stop member 42 having a curved elastic stop 43.

From the foregoing it `will be observed that the gages may be adjusted transversely and longitudinallyv of the platen. The first adjustmentis accomplished by loosening the thumbsciews referred to and sliding the blocks 2l along the' gripper bar. The second adjustment is accomplished by loosening the screws'QS on the front gage and moving the gage member 29'relatively to the arm 26...

The stop member 42 on the side gage may be moved along the arm 35 to adjust the stops 43. i.

Usually the front 4gages are positioned between the grippers.

The paper 45 is placed on the platen either manually or by an automatic feed with the leading edge against the stops 31 and the one side edge against the stop 43. When the platen moves down into printing position, the gripper bar is brought into alinement with it shown in Fig. 5 and this movement of the platen causes the stops 31. to move upward on the platen a slight distance thereby pushing the sheet of paper: into a predetermined position to receive the impression. The extent of the movement is indicated in Fig. 5 by the distance marked 49. This movement of the gages is due to the fact, above set-forth, that the pivot 27 is in a higher plane than the pivot 17. Hence the pivot 27 moves in an arc around the pivot 17 toward the platen, and this op' eration is clearly shown in Figs. 4 and The downward movement of the platen also causes the lug 38 of the side gage 2O to rotate around the pivot 40, but as this latter is substantially coaxial with the pivot 17 no upward movement of the side gage Instead the side ga e moves cause the axis of the pivot 40 is slightly inclined to the axis of the pivot 17; as explained above. The transverse movement of the side gage is illustrated in Fig. 6 as explained and thereby the paper is pushed from the side into -`printing position. When the form is very large the arm 35 is olset as shown so as to register a large sheet of of the paper-in printing position equal to t ie extent of the movement of said stops. This insures that the paper is pro erly registered in the same position for eac impression.

From the above it will be seen that` I have rovided very simplefand easily attacliedp operated wholly by the movement of the platen relative to the gripper bar. Another advantage of these stops is that they need not be detached when the tympan sheet is to be changed. The gages are simply swung upward in order to raise the bail 14 to free the tympan. After a fresh tympan has been placed upon the platen, the gages are let dovn and then the register is the saine as ore.

The invention is susceptible of changes and modification and I claim alls uch as properly come within the scope of the specification and the claims.

I claim:

1. The combination yof a movable platen, a gage support pivotrd parallel to the same., a gage pivoted at an angle to the said support pivot and means for oscillating said support to cause the said age stop to move in an arc in a plane para lel to the surface of the platen.

2. The combination of a movable platen, a

register gages, and "that the same'are gripper bar pivoted parallel to the same, a.

gage block supported on said grip er bar, a gage pivoted on said gage block, t e axis of the gage pivot being inclined,v with respect to the axis of the gripper bar pivot, whereby when said platen is operated the said gage keeping the gage in contact with the surface of the platen.
