To all 1071/0711, it may concern:
Be it known that I, CHARLES WILLIAMS, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Paper-Feeding Mechanisms, of which the following is a specification.
My present invention is concerned with cer tain new and useful improvements in paperfeeding mechanisms such as are adapted to feed paper from a roll and cut it into strips of the proper length and to deliver it to a printing-press.
For convenience of illustration I have shown my invention as applied to a multicolor-printing press; but it will be understood that the mechanism may be applied to other forms of presses.
To illustrate my invention, I annex hereto four sheets of drawings, in which the same reference characters are used to designate identical parts in all the figures, of which- Figure 1 is a side elevation of a multicolor press, showing my improved paper-feeding mechanism attached thereto. Fig. 2 is a transverse vertical section through the upper part of the paper feeding mechanism and press on the line A A of Fig. 4. Fig. 3 is a similar view on the line B B of the same figure. Fig. 4 is a front elevation, on a slightlyenlarged scale, of the cutting and feeding mechanism proper detached. Fig. 5 is a section on the line C O of Fig. 4. Fig. 6 is a detail showing the cooperation of the shearing and ledger blades. Fig. 7 is a front elevation of the paperrollholding mechanism. Fig. 8 is an end elevation thereof. Fig. 9 is a sectional view thereof on the line D D of Fig. 7, and Fig. 10 is a sectional view on the line 10 10 of Fig. 7.
Upon the framework 10 of the press, I secure at each end a pair of posts 11 and 12,
upon which are adjusted by the set-screws 13 the framework of the paper feeding and cutting mechanism, which consists of two plates, one at each end, each end consisting of the two sleeves 14 and 15, adapted to cooperate with the posts 11 and 12 and connected by the V-shaped portion 16, upon the upper end of which is supported one end of the paper-roll 17. Projecting forwardly from the sleeve 15 substantially at an angle of fortyfive degrees is an L-shaped arm 18, the L portion 19 of which projects forwardly and downwardly.
Referring now to Figs. 2 to 5, it will be seen that the arms 19 are connected by the two transverse bearing-rods 20 and 21, secured in suitable bearings in the said L- shaped arms, and there is also a rock-shaft 22, j ournaled in suitable bearings formed in the outer and downward ends of the arms 19. Adjustably mounted on the rods 20 and 21 is a frame comprising a pair of supportingplates 23 and 24, secured in place by the setscrews 25, passing through the bearing-sleeves 26, formed on the upper ends of said plates. These plates 23 and 24 have journaled therein toward their lower ends the feed-rollers 27 and 28, which are compelled to move in unison in opposite directions, so that they will carry a sheet of paper between them by the intermeshing gear-pinions 29 and 30, secured on one end thereof. On the other end of the shaft carrying the feed-roller 28 is secured the gear-pinion 31, which meshes with a gearwheel 32, secured on the shaft 33, extending between the end pieces 18 and journaled in them and in the bearing-plates 23 and 24. The shaft 33 has secured on its outer end a ratchet j wheel 34, with which engages a ratchet-dog 35, mounted on the swinging arm 36, mounted on the end of the shaft 33. A continuously-driven gear-wheel 37 on the machine is secured. on a shaft 38, the outer end of which has mounted thereon the bar 39, containing the slots at either end thereof, one of which is graduated on its edges, as seen at 40. Secured in the slot having the graduated edges 40 is an adjustable bearing-block 41, to which is pivoted a link 42, the other end of which is pivotally secured to the arm 36, so that the continued rotation of the wheel 37 will, owing to the eccentric position of the block 41, cause the ratchet 35 to rotate the shaft 33 a definite number of degrees at each movement, and this rotation, transmitted and increased through the gears to the feed-rollers 27 and 28, will cause the paper strips to be fed between them the desired distance, which, it will be seen, can be readily regulated by adjusting the bearing-block 41 in the graduated slot. It will be apparent that this feed will be intermittent, occupying half of each rotation of the shaft 38 and being inoperative during the other half. Secured in the slot 43, formed in the other end of the bar 39, is the adjusting pin or block 44, to which is pivotally secured the link 45, the other. end of which is adjustably secured in the slot 46, formed in the arm 47, secured to the rockshaft 22. Secured on the rock-shaft 22' a little distance inside of the bearing-plate 23 is a slotted arm 48, in which is pivotally secured in any necessary position of adjustment an arm 49, which in turn is pivotally secured to the short arm 50, projecting upward from the body 51, carrying the helical knife-blade 52. The body 51 has the arms 53, by which the swinging knife-carrying member is pivotally secured by means of studs or bearingpins 54 in the arms 55, which may be formed integral with the lower ends of the plates 23 and 24, but which I preferably make adjustable thereon, as by the slots 56 and set-screws 57, so that the position of the knives can be accurately adjusted relatively to the platens upon which the paper is to be delivered. Extending between and secured to the upper surface of the arms 55 is the ledger-blade 58, with which the helical blade 52 cooperates as it is rocked forward at each revolution of the shaft 38.
The paper-roll 17 is mounted upon a shaft 59, supported in the inverted-V-shaped portion 16 of the feed-mechanismsupporting frame. A pair of conical adjusting-plugs 60 are secured by set-screws in proper position on the shaft 59 to accurately secure the roll of paper from any longitudinal movement on its shaft. The longitudinal position of the roll of paper is secured by means of the set-screw 61, passing through a threaded bearing formed in the top of the part 16 and having the groove 62 formed in its end working in the vertical slot 63, formed in the plate 64, projecting down from the block 65, which is mounted to slide on the top of the piece 16 so far as may be necessary for this longitudinal adjustment. The block 65 has the U-shaped bearing-recess 66 formed in its upper side to receive the shaft 59. The transverse position of this end of this shaft is determined by the set-screw or stud 67, secured in the ear 68 of the part 16, against which one side of the block 65 is securely held by the set-screw 69, passing through a similar ear 70. The adj ustment of the other end of the shaft is cared for by the mechanism shown in Fig. 9, where it will be seen that the bearing-block 71, which is free to slide on the upper surface of the part 16, is held in any desired position of adjustment against the set screw 72, screwed through the car 73 by the helicallycoiled expanding-spring 74, confined between i the block 71 and the car 75.
rotation of said shaft, the feed-rollers are rotated forward to carry the paper between the cutting-blades and onto the platen, which may be adjacent and which is held in the retracted position shown in dotted lines in Fig. 2. At the end of the feeding movement the platen is thrown outward to the position shown in full lines and the strip of paper that has been fed forward is caught between the surface of the platen and the wire springs 76, projecting downward from the plates 23 and 24 in suitable position to catch the paper. As soon as the paper is properly held the reciprocating helical blade 52 reaches the limit of its forward movement and shears off the paper and retreats, leaving the parts ready for a fresh operation. Of course it will be understood that the platens are provided with the customary paper-clamps which secure the portion cut off firmly before the platens are advanced to printing position.
The plugs 60 are provided with suitable means to engage the roll of paper so as to insure the rotation of the roll with the shaft 59. For this purpose the plugs may be provided with serrations, as shown in Fig. 10, by forming the conical portions of the plugs with alternate ribs and grooves along the axial line. It is of course obvious that any other means may be employed.
While I have shown and described my invention as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of modifications.
What I claim as new, and desire to secure by Letters Patent of the United States, is
