FEED-GAGE FOR PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 603,246, dated May 3, 1898. Application filed June 12, 1897. Serial No. 640,564.. (No model.)

To ooZZ whom zit-may concern:

Be it known that I, CLEMENT E. BALDING,

of Holton, in the county of Jackson and State purpose of supporting the material at the proper elevation and also for-securing the desired margin thereon.

The invention consists in the novel features of construction hereinafter fully described and claimed, and illustrated by the accompanying drawings, in which Figure 1 is a view of the platen of a printing-press, showing my improvement applied 'thereto and also the guard for the gripperflngers. Fig. 2 is a detached perspective view of the attachment. Fig. 3 is a detail view of the guard for the gripper-fingers.

Referring to the accompanying drawings, 1 indicates the plate, having a flange 2 upon its lower edge, by means of which it is secured to the platen of the press by raising the lower clamp and inserting said flange therebetween and pressing the clamp back into position.

3 indicates oppositely-extending horizontal arms, which are secured to the plate by bolts 4, said bolts having squared ends to receive a key by means of which they are loosened or tightened, as desired. The inner or meet-' ing ends of these arms are provided with cogged segments 4: which are adapted to intermesh, so that when one arm is raised the other is correspondingly moved. Formed in these arms are the longitudinal slots 5, in which the upwardly-extending arms 7 are movable, said arms being circular at their upper ends and formed with flanges 8 to form a seat against which the edge of the material rests which is to be printed. These arms are adapted to be secured at their upper ends by paste or in any other desired manner'to the tympan when the desired adjustment has been effected. The perforation 9 is formed on each of the circular ends, so that water may be poured therein to loosen the paste when it is desired to readjust the arms. One of the arms 7 is provided with a lateral eX- tension 10, and movable on said arm is the marginal gage 11, which is curved upwardly and terminates in a circular portion which is secured to the tympan in the same manner as the arms and which is also provided with a flange against which the vertical edge of the paper is adapted to rest. Thehorizontal portion of this arm is slotted, as indicated at 12,

through which'extends a screw 13-, which passes through the lateral extension, and it is provided with a nut, and thus the arm or gage is adjustable to secure the desired margin.

' In order to prevent the gripper-fingers from coming in contact with the gage before engaging the paper or the material being printed, I provide the plates 14, which are formed in the present instance in substantially the shape of a maltese cross having the horizontal arms thereof bulged, as illustrated, and provided on the edges of the vertical arms with the flanges 15, by means of which the plates are positioned upon the frisket-fingers, the same being secured thereto by screws 16, which pass through said flanges and engage the fingers. Thus the horizontal portions of the plates will engage the paper on opposite sides and prevent the gripper-fingers from coming in contact with the gage, thus permitting said fingers to, secure the material during the impression and remove it from the type after the impression is received.

From the above description it will be seen that I have produced an attachment for platen printing-presses whereby the paper may be supported at the desired elevation upon the platen and also positioned to secure the proper margin.

Having thus described the invention, What is claimed as new is- 1. The combination of a plate, adapted to be secured to the platen of a press, arms pivoted thereto, and carrying intermeshing cogs on their inner ends, secondary arms adj ustable on said arms, and a marginal gage ad justable upon one of said secondary arms, substantially as set forth.

2. The combination of a plate having a flange which is adapted to be secured by the clamp of the platen, arms pivoted to the plate,

and carrying intermeshing cogs on their inner ends; said arms having longitudinal slots, secondary arms adjustable in said slots, securing means carried by the outer ends of said secondary arms whereby they are attached to the tympan, seats formed upon the upper ends of said arms against which the sheet to be printed is adapted to rest, sub stantially as set forth. 7

3. The combination of a plate having a flange which is adapted to be secured by the clamp of the press, arms pivoted to said plate and carrying intermeshing cogs on their inner ends, said arms having longitudinal slots, secondary arms adjustable in said slots, securing means carried by the outer ends of the said secondary arms whereby they are attached to the tympan, seats formed on the upper ends of said arms against which the edge of the material is adapted to rest, whereby it is supported at the desired height, and

a marginal gage adjustable 011 one of said secondary arms, substantially as set forth.

4. The combination of arms secured to the platen of a press and adjustable thereon, secondary arms adjustable upon the firstnamed arms, amarginal gage adjustable upon one of said secondary arms, plates adapted to be positioned upon the gripper-fingers of the press, and lateral1y-extending arms carried by said plates, said arms being bulged outwardly from the platen, so as to grip the opposite sides of the paper without interfering with the gage, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
