ATTACHMENT FOR PRINTING-PRESSES.

sPEoIFIoATIoN forming part of Letters Patent N... 7 0,127, dated May 17,1904.

' Application filed August 3, 1903.

To all whom it may concern:

-Be it known thatI, CARLos S;INSKEEP,3. citizen of the United States,'residing at Swayzee, in the county of Grant and State of Indiana, have invented a new and useful Attachment for Printing-Presses, of which the following is a specification. This invention relates to attachments for hand-operated printing-presses; anditconsists in improved means for holding the blanket on the platen and in an improved paper-feeding and self-inking mechanism.

The object of the. invention is to provide a hand-operated press with means for retaining theblanket or tympan-sheet on the platen in such manner that the wrinkling thereof will be positively prevented and to provide a simple and inexpensive device whereby the type will be automatically inked and the paper fed automatically into position for printing.

A further object of the invention is to provide a paper-feeding and self-inking attachment for hand-operated printing-presses by which the inking of the margins of the paper is prevented and in which the parts are so arranged that the paper-feeding tapes are kept from coming into contact with the inkingof a printing-press-with the attachment'shown in operative relation thereto, the bed of the press being shown as in position for printing and a sheet of paper being shown on the carrying-tapes above the bed. Fig. 2 is a plan View of the structure shown in Fig. 1 with the upper portion of the frame. in which the platen moves removed.

Referring now to the drawings, in which Serial rim 168,085. (No model.)

corresponding parts are designated by the same characters of reference throughout the several views, 1 designates the platen of ahandoperated printing-press, which is mounted for vertical reciprocation in a frame comprising the vertical side columns 2 2 and the arched cross-piece 3. The platen 1 will be operated by means of any suitable mechanism.

In orderto hold the blanket (indicated'at 4) in proper position on the under side'of the platen and to prevent the possibility of the formation of wrinkles in the blanket, I make use of a blanket-holding device comprising a frame 5, of such dimensions that it will just fit on the outside of the platen 1, and a sheet 6, of muslin or other thin smooth-surfaced fabric, which is stretched tightly over the frame 5 and secured-thereon by any suitable fastening means, as by tacksdriven through the fabric and into the upper surface of the frame over which the edges of the fabric are drawn. To hold the blankct-holder in position on the platen, I prefer to employ two transverse bars 7 arranged near the ends of the frame 5 and secured thereon by means of bolts 8 and thumb-nuts 9.

The manner of using the blanket-holding attachment will be clearly evident from the drawings. The blanket, which rests upon the sheet of muslin, is placed in proper position thereon to correspond to the outlines of the platen, and the frame 5 is then fitted over the platen, as shown, with the-blanket and the sheet of muslin beneath the platen. The

cross-bars 7 are then placed upon the bolts 8 'and the thumb-nuts 9 are screwed down until the frame has been raised sufficiently to straighten out all the irregularities in the surface of the blanket and to'eause it tolie 'perfectly smoothon the under side of the platen.

The bed of the press (indicated at 1'0)is mounted for reciprocation upon ways11=and is given a to and-fro"movement'by suitable mechanism actuated by means ofacrank 12.

The self-inking attachment comprises frame composed of the hinged sections 1.3 and 14 and is suspended by means of hooks 15 from the ways 11, on which the bed reciprocatejs. The sections 13 and 14: are hinged together at the rear end, as shown, and the upper section 14 is higher at the rear than the forward end to furnish suitable support for an inclined feed-table 16, which is removably supported thereon. In order to hold the two frame-sections in proper relative position at their forward ends, hooks 17 are provided on the upper section and eyes 18 for engagement therewith are provided on the lower section. Inking-rolls 19 are rotatably mounted in suitable bearing-blocks 20, and the latter are supported by means of links 21, attached at one end to the bearing-blocks 20 and at the other end to the lower side members of the framesection 14. Attached to the upper surface of the bearing-blocks 20 is a curved sheetmetal shield 22, which so covers the inkingrolls-l9 that they do not contactwith sheets of paper or tapes moving above them. The ink-table, from which the ink is supplied to the rolls 19, is made of metal or wood covered with metal and is mounted at the rear of the reciprocating bed 10, as shown at 23. The table 23 is'of such width that it may reciprocate with the bed between the side pieces of the frame-sections and has at the rear thereof a few inches abovethe ink-receiving surface a transverse bar 24, whose utility will presently be explained. v

The paper-feeding mechanism comprises a set of tapes and operating devices therefor. The tapes (three 1".1 number and designated 25, 26, and 27 are all attached at one end to the bar 24 and at the other end to a roll 28, which is rotatablysupported upon swinging brackets 29, mounted in the forward end of the upper frame-section 14. The tapes 25 and 26 extend forward from the bar 24 and pass under a bar 30, mounted at the forward end of the pressbed 10, and then extend backward to be secured at their ends, to the roll 28. The tape 27 is wound in an opposite direction to the tapes 25 and 26, and it is also fastened at its rear end to the bar 24; but. instead of passing forward under the bar 30 upon the bed 10 it passes directly to the roll 28 and is attached thereto on the side opposite the points of attachment of tapes 25 and 26. Owing to the way in which the tapes are arranged the reciprocation of the bed 10 will cause the tape27 to bewound on the roll 28.

during the forward movement of the bed and will cause the tapes 25 and 26 to be wound on the roll during the rearward movement of the bed. All of the tapes 2 5, 26, and 27 pass over a guide-roll 31, supported in the side pieces of frame-section 14 a little to the rear of the inking-rollers, and upon the tapes 25 and 26 there is mounted a gage-bar 32, by means of which sheets of paper will be fed to the proper position for printing when the bed travels forward in the ways 11. The forward movement of the tapes will move the gagebar to a point adjacent to the roll 25, so that when the paper is fed between the roll 25 and printing position by means of the gage-bar 32. Upon the completion of the printing operation the platen 1 will rise and the bed 10 will move rearward. At the same time the tapes will carry the printed sheet rearward also to such position that it may be readily removed and a fresh sheet placed upon the tapes to be carried forward upon the return movementof the bed of the press for printing.

By means of the self inking and feeding attachment above described it will be evident that one person will be enabled to operate the press unaided, as the crank by means of which all the movements of the press are brought about may be readily turned with one hand and the feeding of the fresh sheets to the tapes and the removal of the printed sheets therefrom can be easily done with the other hand.

Having thus described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent, 1s
