SPECIFICATION forming part of Letters Patent No. 413,887, dated October 29, 12889.
Application iiled July 25, 1889. Serial No. 318,656. (No model.) I
To all whom it may concern..-
Be it known that I, AUGUST R. BARTLAU, of Plainfield, Union county, VNew Jersey, have invented an Improved Cutting Attachment for Printing-Presses, of which the following is a specification.
This invention relates to a cutting attachment for printing-presses which may be ad- Justed to cut .paper printed 4upon the pressv yinto different lengths.
The invention consists in the various features of improvement more fully pointed out in the claims.
In the accompanying drawings, Figure lis a longitudinal section of my improved cutting attachment on line .fr Qc, Fig. 2. Fig. 2 is a top View thereof. Figs. 3 and 4 are face views of the cams c d..
u The letter a represents the frame of a printing-press, in which is hung a revolving shaft b, upon which are mounted a pair of cams c CZ, of equal diameter. These cams are set side byside, the hub of one being slipped over the hub of the other, and are adjustably connected by means of bolt e, having nut c. This bolt is tapped in cam c and engagesv a curved slot CZ of `cam CZ. ln this way the cams may be turned upon their shaft, after which theyare tightened up by set-screws, as usual. The working-edge of each cam is partly raised and partly sunk, and by turning the cams a suitable distance their raised parts may be' made to overlapto any desired extent. Thus it will. be seen that the working-edge of the combined cams may be changed to change the relative extent of sunken and raised surface. Upon a shaft f-also hung in frame athere is secured an arm g, provided with aroller h, that engages the working-surfaces of both cams c d, Fig. 2. To the shaft f there are also secured a pair of arms c', provided with stop j, above a fixed block j. The arms 1I are provided with extensions i', which engagethe sliding bearings 7c. In these bearings is hung the shaft k2 of the upper feed-roller k. The feed-roller la is situated above and is intergeared with the lower feedroller Z.
m is the upper cutting-cylinder, placed above the lower cutting-cylinder n, to which the 4power is applied from the main press. These cylinders are only so far apart as to permit a sheet of paper to pass between them. The cylinder n transmits motion by wheel n3 on its shaft, and by wheels n2 n to shaftb. The wheel n3 also engages a wheel m3 on shaft of cylinder m and revolves the latter. Moreover, the wheel n3, by wheel p, revolves lower feed-roller Z.
The operation of the device is as follows: The paper A to be cut is from its deliveryroller passed over pulley q, thence over a suitable weighted tension device q and pulley q2 through the stop mechanism j j. Thence the paper passes between the feedingrollers Zr. Z, and finally between cutters m n. Motion being imparted `to the machine, it will be seen that'when the roller h is raised by the raised working-surfaces of the joint Y cams cd the stop j is raised, so as to allow the passage of the paper between the stop and the block j. At the same time the upper feeding-roller k is lowered upon the roller Z. Thus these feed-rollers engage the paper and carry it to the cylinders m n to be cut. As soon as the roller h is brought vopposite the sunk surface of joint-cams c CZ, pull-springs r draw arms i down to close the stop'mechanism jj and grasp the paper. At the same time the roller k is raised from rollerZ and the feed is stopped. Thus the desired intermittent feed is imparted to the machine.
As already described, the length of time during which the machine feeds may be regulated by adjusting the cams c d, and thus paper of different lengths may be cut.
l. The combination of a pair of adjustable cams with a shaft f, carrying arms g 7l, the arm g, having roller h, that engages the cams, and t-he arms t', having stop j, and with the block j, substantially as specified.
2. The combination of a pair of adjustable cams with shaft f, arm g, and roller h, engaging the joint surfaces of the cams, and with the arms c', having extensions the arms t, carrying stop j, and the extensions i', engaging' the adjustable bearings of a feedingroller, and with the blookj', substantially as anisln ope-rated by the arms, and a pair of and for the purpose specified. cutting-cylinders, substantially as and for 3. The combination, in :L cutting attaohthe purpose described.
ment for printing-presses, of lche following AUGUST R. BARTLAU.
