MICROMET'ER' FEED GUIDE FOR PLATEN PRESSES.

Application filed October 16, 1924. Serial No. 743,992.

To all whom t may concern.'

Be 1t known that I, FRANK MERRYMAN, a citizen of the United States, residing at Gorvallis, in the county of Benton and State ofk Oregon, have invented certain new and useful Improvements in Micrometer Feed Guides for Platen Presses, of which the following is a specification.

This invention relates to micrometer self registering feed guides for platen presses, and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a feed guide of simple form, involving a minimum number of parts, and which is adapted to accurately position a sheet upon the platen of a press, whereby proper registration may be had in producing multi-color printing.

`With the above object in View, the invention includes a bar which is pivotally connected with the platen of the press and ladapted to swing with relation to the platen, as the platen moves toward and away from the type. Guide arms are mounted upon the said bar and means are provided for accurately shifting or adjusting the guide arms along the bar and transversely across the platen. The guide arms are provided with movable fingers, and the fingers are so mounted and arranged that they may move with relation to the sheet supporting surface of the platen, and as the platen moves in order thatthe fingers may clear the chase and the type, thus making it possible to prodiice the printing iii close proximity to the edges of the sheet and in proper registration.

Figure 1() is a detail section taken on the line lO--lO of Fig. 7. K

As illustrated in the accompanying drawing, the press to which the device is applied .includes the platen l, having the bail 2 hingedly mounted at the edges of the platen in a conventional form.y A gripper bar 3 is hingedly connected with the platen 1, and is arranged to swing with relation to the platen as the said platen moves toward and away from the type, and the bar is provided with an arm 4, having aV roller 5 journaled thereon, and which is adapted to move around the periphery of an eccentric of the press (not shown), and which swings the arm during the movement of the platen, as hereinbefore described. The bar 3 is provided-with one or more longitudinally disposed slots G. The block 7 is fixed to the intermediate portion of the bar 3 and the screw is lioiirnaled at its inner end in the bracket 8 and at its intermediate portion through the block 7.

`The screw 8 is provided, at its other end, with a kniirled head 9.

threaded upon the intermediate portion of A block l0 is the screw, and-a spring supported loop 1l is carried bv the block .10, and is provided at its inner side with a thread adapted to engage the thread of the screw. It is apparent that by depressing the loop 11,., the. threads thereof may be moved out of engagement with the thread of the screw, and consequently the block will be free to move along the bar 5. When the thread of the loop 11 is in engagement with the thread of the sciew 8, the said screw may be turned by using the head 9,` and consequently the block may be accurately adjusted along the bar 3. The block l() carries another block 30, to which it is hingedly connected. Aside gage, arm l2 is pivoted upon the last mentioned block by means of the screw The arm 12 has atiirned under portion of lug 32, which comes in contact with the edge of the platen when the grip bar 3 is rocked into the plane of the platen. A plate 13 is adjustably mounted upon the plate 12 by means of the friction ears 12 which extend from the edges of the plate 13 over upon the plate 12, and the plate lf3 is provided with Cil a side portion 14 adapted to be slipped through incisions 1 5 provided in the platen sheet, and whereby the edge of the portion 14 of the plate may serve as a stop for the printing sheet which is fed upon the platen.

It will be seen that as the platen 1 moves toward and away from the type, the gripper bar 3 is rocked with relation to the platen, and consequently the block 30 is moved toward and away from the platen. This relative movement causes the projection 32 to come in contact with the edge of the platen 1, and produces swinging movement in the parts 12, 13, and 14, with the screw 31 as a pivot in the same plane or parallel with the same plane, as the surface of the platen. Thus the side portion 14 comes in contact with the side edge of the sheet to be printed on, as it moves in the above described manner, and brings the Vsheet toy proper position sideways for the impression.

Each block 7 has another block 33 pivotally-connected thereto by means of pin 33 which extends through block 7 and into block 33 being locked in engagement with block 33'by screw 7 The screw 17 is carried bythe block 33, and `the block 13 extends into the block33 and is threaded upon said screw. An arm 19 is adjustably mounted upon the last mentioned block, and carries at its free end portion a plate 20, which is adapted to rest upon the platen 1.

It will be seen that as the platen 1 moves toward and awayfrom the type, the gripper bar 3 is vrocked with relation to the platen and consequently the arm 19 is moved across the platen, carrying with it the plate 20. As the sheet, upon which the printing` is to be produced has one of its end'edges bearing against the, stops 20 of plate 20, the said sheet is moved, during the movement of the platen, so that it is properly presented to the type, when the platen arrives at the impression position. Mortices are provided in the blocks 7 and 10 to receive bars 34. Other mortices 35 are provided in the blocks 33 and 30, and also ina portion of the arm 12 to receive the bars 34. These bars 34 hold vrthe rod 19 and plate 2O and the arm 12 and plate 13 clear of the platen, when the bars 34 are pushed into the mortises 35. This detachable means is convenicnt, when a new platen sheet lis wanted, or when it is necessary to raise the top of the platen sheet for the make ready.

In lthe form of the invention, as illustrated in Figure 8 of the drawing, means are provided for causing movement of the finger l21,-with relation Vto the plate 20, and

the platen, Vand the .said means includes a bracket;22, which is mounted upon the plate The block 23 is mounted upon the platen 1, and a lever 24 is pivoted upon the block 23, and is provided at one end with a slot 25 which receives a pin 26 carried by the bracket 22. A lever 27 is Vpivoted upon the block l23 and has a pin and slot connection at one end with the finger 21. The lever 27 is provided, at its opposite end with a set of gear teeth 28, which mesh with the gear teeth 29 provided upon the lever 24. Therefore, as the arm 19 and the plate 2O move with relation to the platen, and during the movement of the platen 1, the levers 24 and 27 are swung upon the block 23, whereby longitudinal movement is imparted to the iinger 21, and this movement is sufiicient to cause the finger to uncover the surface of the printing sheet, when the sheet is presented to the type.

Having thus described the invention, what is claimed is:

1. In combination with a platen having a bar pivotally mounted thereon, a micrometer feed guide comprising a bracket mounted upon the bar, a screw journaled at one end in the bracket, ablock having screw thread engagement with the screw, and a guide carried by the block.

2. In combination with a platen having a bar pivotally connected thereto, a micrometer feed guide comprising a screw mounted along side of said bar, a block mounted for sliding movement upon the bar, a spring supported loop having a threaded section and movably mounted on the block, and adapted to engage the thread of the screw.

3. In combination with a platen having a bar pivotally connected thereto,.a feedguide comprising .a block mounted upon the bar, a second block adjustably mounted upon the first mentioned block, an arm carried by the second block, a plate carried by said arm and adapted to lie upon the platen, and aI finger with which the plate is slidably engaged.

4. In combination with a platen having a bar pivotally connected thereto, a feed guide comprising a block mounted upon the bar, a second block adjustably mounted upon the first mentioned block, an arm car ried by the second mentioned block, a plate carried by the arm, a finger slidably mounted upon the plate, a stationary member positioned upon vthe platen, levers fulcrumed upon the member and having intermeshing gear teeth, one of said levers being connected with the plate and the other with the finger.

In testimony whereof I aflixmy signature.
