PERFORATING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 396,240, dated January 15, 1889.

Serial No. 229,678. (No model.)

T 0 all 1071/0711, it 77mg/ concern:

Be it known that I, CHARLES SEYBOLD, a citizen of the United States, residing at the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Perforating- Machines, of which the following is a specification.

The object of my invention is to produce a machine for perfor-ating paper or similar material in which .the feed and punching` mechanism can be regulated and in which the feed and punching mechanism are automatic.

In the acconipanying drawings, forming part of this specification, Figure l is a front view o f my machine in elevation. Fig. 2 is an end view of the left-hand side of the machine. Fig. 3 is an end view of the right-hand side of the machine. Fig. #i is a view of the lefthand end ot' the machine, looking toward the inside from the right, the feed-rolls, shafts, bridge, vc., being shown in section. Fig. 5 is a cross-section through the punch -bar, punch.-

Abar key, and mechanism for working' the punch-bar key in and out of the eccentricrods to raise or lower the punch-bar carrying the punches. Fig. 6 is a section showing the yoke, friction-disks, angle-lever, segment-cam or wedge-stud, pin, and accompanying mechanism. Fig. '7 is a side view of one of the perforating-punches. Fig. S shows the perforating-punch attached to the punch-bar, the lower portion of the punch being in cross-sec` tion. Fig. 9 is a bottoln viewA of the perforating-punch. Figs. IO and il are views of the mechanism for raising and lowering the feed-roll and' gage. Fig. l2 shows a roller, the levers M, and the gages h' 3 in position. Figs. 5, G, 7, S, andi) are details drawn to a larger scale than the other figures, and are nearly one-half of the actual size of the machine shown.

The IetterA represents the frame of the` machine, similar on both sides. A represents the left-hand end,.and A2 the righthand end, of the machine. These ends and the frame A may be made of any suitable contour or sha-pe. The ends A A2 have suitably secured to them, preferably cast in one piece therewith, the pieces A3. These pieces extend outward from the main frame, as shown in Fig. l, and have two arms, c d, slotted at a. a', to receive the journal-boxes of vthe feed-rolls. These pieces A3 also contain the central slot or recess, d2, in which the boxes .of the punch-bar slide. The two arms f1 c of the pieces A3 are connected by the strip ai. vB represents the eccentric or operating shaft, which passes through both ends ot' the machine and through and supported by the housings B. On the right-hand' end of the ma- .chine this shaft B carries the wheel B2 and .pulleys B3 B4, and at the left-hand end the gear-wheel O. To each end of this shaft B is attached an eccentric-connection, O. To the eccentrics C are attached at each end of the machine the eccentric-rods D. These rodsD pass through the eccentric-yoke D', and are held in position by any suitable means.

The eccentric-rods pass through the heads or caps D2, which are hollow and receive the ends of the punch-barD. The punch-bar D3 passes through and is supported by the boxes D4, which play in the slots or recesses d2. The punch-bar Ds in its under side has a groove in which iits and plays the key E. This key is of any suitable construction, and is composed of the long part b and the short part b.

The parts h and ZJ of the key E work in and out of the recesses b2 in the eccentric-rods D.. On a stud, E', rigidly secured at one end to the end of the machine in the housing E2,

secured the gear-wheel E3 and the operatingI A.

friction-disk El. The gear-wheel E3 and operating-disk E1 are rigidly secured together by the pins d. Both the gear-wheel E3 and disk E4 fit on the stud E loosely, allowing the disk E'1 and gear E3 to turn simultaneously when motion is imparted to the gear-wheel E3 bythe gear-wheel O. The angle-lever F is loosely fulcrumed on this stud E', and is held in placev by the nut d. This angle-lever F is slotted at d2. A block, d, is attached to the eccentric-rod D. Then the eccentric-rod D is in motion, the block d3 slides back and forth in the slot d2, and consequently vibrates the lever F. This lever F carries the segment cam or wedge e forward and backward between the block e on the eccentric-rodD and the cap e2. A slot, c3, is cut in the wedge e. Through this slot es passes the set-screw el. Between this IOO screw e4 and the wedge c is interposed the washer ef. By means of this slot e3 and the set-screws a the wedge e may be set nearer to or farther from the cap e2 and block e', thus enabling said wedge to enter a greater or less distance between cap e2 and block e toA suit the feed required.

F represents a stud which passes through the end A of the machine. It is screw-tln'eaded on its inner end to receive the nut 7L, by means of which it is rigidly secured in position.

G G represent two friction-disks held together by the pins 7L. (See Fig. G.) The disk G has the sleeve 712, and the disk G the sleeve 712, the sleeve h2 fitting over the sleeve h2, which iits loosely over the stud F. (See Fig. G.) The disk l is firmly held in position by the washer 7L" and nut h5. Rigidly attached to the disk G by screws 'iy is the gear-wheel i2. This gear-wheel G2 is recessed at i to receive the spring G2, interposed between the recessed portion of the gear-wheel G2 and the washer li2 and around the sleeve 71,2 of the disk G.

II represents a yoke. Through the :frame end A pass the rods i2, having around them the coiled springs it. The yoke II is thrown back into position by these springs, which lie between the yoke-arms and the frame end A when the wedge c is on its backward movement. The nut-and-washer connection holds the rods in position.

The gear-wheel G2 meshes with the two gear-wheels H2 and IF. (Shown in dotted lines in Fig. 2; also shown in Fig'. l.) These gear-wheels H2 and H2 are attached to and operate the lower feed-rolls, H"L H5. The lower feed-rolls, H'L and Hi", come in contact with and impart motion to the upper feed-rolls, Il and HT. These feed-rolls are journaled in boxes 7a h2 s2 k" on each side, which boxes rest in the slots a in the pieces A2.

The feed-rolls are preferably of the peculiar shape shown in Fig. l-that is, they have an uneven surface similar to a corrugationdand when not in use, or when it is desired to repair a certain part of the machine, these rollers can be'lifted up out of the way and allowedto rest in the arms a.

On the stud J, suitably secured, is the gearwheel J On the same stud, J, is also secured the gearvheel J2. On the eccentric-shaft B is secured the gear J2. The gear J2 meshes with and imparts motion to the gear J2, and the gear J meshes with and imparts motion to the gear J4, which turns the shaft K. This shaft is j ournaled in each side of the machine, passing through the frame side A2. On this shaft K is secured the cam K by the sleeve Z.

Loosely secured in each side frame, A A2, of the machine, and extending from one side of the machine to the other, is the rod T. The pawls M and M are rigidly secured on the rod T, the pawl M on the side where the cam K is present, and pawl M'L on the opposite side. The pawl M has three iingers,t t i2, shaped as shown i n Fig. l0. The pawl ML has only the two fingers t t2, which are similar in shape to the fingers of pawl M. On the feedroller H5 is secured the lever M, having the slot M2, (see Figs. 4 and 10,) in which slot works the gage-block M2. This gage is set to bring the sheet to be perforated properly under the punches. The fingers t of the pawls M and M, while the finger t of pawl M is passing over the raised surface of the cam K, elevate the feed-roller H, so that the sheet can be properly slid between the rollers to the gage M2, and as soon as this is done the finger t of the pawl M is riding over the drop portion of the cam, and the roller H6 :falls into position owing to the fingers t dropping, and the paper is fed under the punches. I preferably only employ one gage, M2, but may employ one ateach side of the machine. The rod vT being loosely secured in the sides of the machine and the pawls rigidly secured to the rod T, allows said pawls to work simultaneously when the finger t of pawl M is passing over the cam K. The [ingert2 of pawl lll supports the gage M2, and is thereby adapted to elevate the same at the same time the arm `lflowi ers the roller H, The pin I-I carries at its inner end the finger m, secured on the pin by the set-screw m. On the cam K is secured the block K2. Through the slot m2 in this block K2 passes the set-screw m2, which cures the block to the cam in one of the holes n. This mechanism on the left-hand end of the machine is the feeding mechanism. I shall now proceed to describe the punching or perforating mechanism.

On the shaft K is the gage-wheel L, carrying the pins n. These pins n fit loosely in the holes provided for them and are held in position by the set-screws n2, by turning which the pins can be slid back, as shown in Fig. l.

The sliding box D4 on the right-hand side I OO- of the machine contains the slot n2 and the l recess nl. The box D1 is held in position by Jthe screws n, In the lower part of the box DA1 is the screw-threaded hole 0, in which is screwed the piece o. Interposed between this piece o' and the part L of the piece A2 is the spring L2, which supports the punchbar and box D". Through a hole in the arm L2 and in the piece o passes a plunger, L4. Extending downward from the arm L2 the rod 02. Thisrod passes through the guide o2, which guide is rigidly attacheiil to the side of the machine, shown in Fig. l. Extending from the arm L2 and guide o2 is the spring o2. This spring' 0^L pulls the arln L2 and plunger L4 downward into position. Attached to the lower end of the rod 02 by set-screw p is the double-inclined cam p. The pins n ride over these inclined faces on the cam p', and consequently raise or lower the cam, and with it the rod o2, and through it the arm L2,which elevates or depresscs the plunger LL. This plunger L4 has the cone-shaped head s and the annular concaved head. s', working in the recess n4. The ends of the short and long portions of the key E meet in this recess fn. and terminate in inclined projections s2, which fit and work inthe concave portion of the head IIO the pins a', the plunger is elevated, and the concave head s draws the inclined faces of the projections s2 over its concave face and brings the long and short parts b and b of the key E together and out of the recess b2 in the eccentric-rods D, elevating the punchbar and bringing the punches up off the paper to .be perforated; lout when the cam p' has passed over one of the pins n' and drops down the cone-shaped head scomes down and parts the long and short portions l) and b' of the key E and forces them into the recesses b2 in the eccentric-rods, and the punch-bar is brought down and the punches into contact with the paper, when they perforate it.

Then the cam p' rides over another pin, n',

. the key is again withdrawn and the punchbar and punches elevated. By pushing the pins backward, so that the cam p' passes them, the punching is longer continued and the length of the lines of perforations regulated.

I provide a pin on the face of the disk or wheel L to correspond with each downward descent of the eccentric-rods or with each rotation of the shaft B-that is to say, every time the eccentric-rods are about to descend one of the pins will come under the cam p' and will operate to raise said cam (and the punchbar will not be drawn down)-that is, when the pin is in its forward or operative position; but the cam will not be operated, and consequently the punch-bar will be drawn down by the parts b engaging the eccentric-rods when' the pin in the wheel L is in its backward or inoperative position.

N represents one of the punches. These punches have two jaws, N N2, which encircle the punch-bar D3, and are tightly held in position ou the punch-bar by the boltfconnection N3. Between the wings fw of the punch N lies the block N4, which carries the perforating-pins w'. These pins are properly set in this block N1, and the metal, N5, poured in and around them, by which these pins w' are rigidly held iii position.

P represents a stripper. This stripper is held in position by the set-screws fwworking in the slots 'il-3. I also provide springs w1. (Shown in dotted lilies in Fig. 7 \Vhen the punch N comes down, the stripper P rests on the paper and holds it tight while the perfo rating-pins perforate the paper, and as soon as the punch leaves the paper the stripper is again held in position by the springs 104. The object of this to keep the paper from tearing and prevent the paper following the perforating-pins w. As many of the punches N may be used as desired.

The machine operates as follows: The belt being adjusted on the pulley B3, motion is imparted to the eccentric-shaft B, (the paper to 'be perforated having been adjusted on the bridge R by the gage M3 and the pins a', and the block K2 having been adjusted,) which works the eccentric-rods D and the gear C, meshing and impartingmotion to the gear E3, which imparts motion to the friction-disk E4,

which, being gripped by the disks G and G', imparts motion to them, and the disk G' imparts motion to the gear-wheel G2, and this gear-wheel meshes with and imparts motion to the gear-Wheels H2 and H3, and they operi ate the lower feed-rollers, they in turn imparting motion to the upper feed `rollers. The eccentric-rod D ou the left-hand side of the machine, imparting motion to the block d3, which works in the slotfl-2 of the lever F, and working back and forth in said slot, tilts the said lever F back and forth, forcing the segment camor wedge @between the block e' on the eccentric-rod and the cap e2, forcing the yoke I-I inward, and the arinsj of the yoke, impinging against the disk G', press said disk G away from the operating-disk E3, consequently stopping the feed, and in this interval the punch-bar carrying the punches N is depressed and the desired perforations made. The springs li4 throw the yoke II back into position, and the spring G3 returns the gearwheel G2 and disks G and G. Gear-wheel .I meshes with and imparts motion to the' gearwheel J, which imparts motion to the shaft K, carrying the gage-wheel L, on which are the )ins/12' and the wheel. L revolving the D pins coming in contact with the inclined faces ,of the cam p', the said cam rides over them, thus elevating the rod o2, and through this ,rod the plunger L4, and the concave surface l of the concave heads', riding' over the inclined projections 32 on the key l, retracts them from the eccentric-rods D; but as soon as the cam p' has passed over one of the pins n' it drops and the plunger L4 falls, the coneshaped head s forcing the two portions Z) and b' of the key E apart and into the recesses in the eccentric-rods, and they, being in motion, carry down the punch-bar D3 with thepunches, and the desired perforation is made. This operation is continued until the sheet has -IIO passed through the feed-rolls.

Vhile the feed is operating, the pawl- M is traveling over the face of the cam K', and when the linger t' is traveling theraised surface of the cam the linger t raises the roller H, so that the paper can be placed in between the feed-rollers, at the same time allowing the lever M', with the gage Mi", to fall, and when traveling the drop-surface of the cam allowing the roller H to fall, and raise the lever M', with the gage M3. (See Figs. 4, lO, and ll.)

In order to regulate the feed, the wedge e may be set forward or slightly backward through the agency of the slotcg and set-screw el. This will shorten or lengthen the stroke of the wedge. A

Suppose the machine is set to punch or perforate every two inches. This requires a feed of two inches at regularintervals; and, again, suppose it is required to punch at two and one-half inches. This makes afraction of an inch-viz., the half-inch. In order to meet this I` adjust the block K2 in the proper hole in the cam K', and the finger m on' the pin H' IOO Will ride over this block K2 and pull the yoke I-I against the disk G' and allow the feed-rolls to feed one half-inch before the wedge e iinpinges against the cap e?. The regular feed of two inches follows, thus making the required feed of tWo and one-half inches.

The bridge Ris a cast-iron piece extending from one end of the machine to the other. The arrows on the gear-wheels and cams show the direction in which they travel.
