FEEDING 'AND MOISTENING- DEVICE FOR SECURTNG A REINFORCING-STRIP ABOVE THE PERFORATEID EDGE A STRIP. i

Application filed January 28, 1911a. ','sefia11vo. 744,636.

To all whom it may concern: 7 v

,Be it lmown that I, HERMA N GALL, a subject of the Emperor ofAustria-Hungary, residing at Berlin, Germany, have invented certain new and useful Improvements in Feeding and Moistening Devices for Securing a Reinforcing-Strip Above the Perforated Edge of a Strip, of which the following is a full, clear, and exact specification.

The invention relates to improvements 111' devices for perforating paper particularly to improvements in the feedingand mois tening devices for securing a reinforcing strip above the perforated edge of the paper and in which a portion of a gummed reinforcing strip is advanced, moistened, cut off and attached along the perforations.

The novel feature of, and important improvement in the paper perforator according to my present invention, as compared with the known devices,-is to be seen in the fact that the movementof the strip is caused by a sliding piece which is positively operated by means of a lever, and which carries a point engaging the paper, and coming free at the end of each forward movement, re leases the paper.

The moistening of the strip is efiected in the well known manner by means of a closed, oscillating water receptacle containing a suitable absorbing means and provided with springs, which when pressed against the gummed paper strip are compressed and which by their expansion during thelowering of the water receptacle give the .paper strip free and have the tendencyto cling to the absorbing means. By this arrangement, a reliable feed for the strip is provided and the apparatus is protected against being soiled during the process of the moistening.

In the accompanying drawings: Figure 1 shows the general arrangement of a paper perforator according to the present invention in its position of rest, partly in elevation and partly in vertical section. Fig. 2 is a top plan view partly in horizontal section on line 21-13, Fig. 1. Fig. 3 shows the device for giving to the paper its initial motion with thevmoistening device resting against the strip, and Fig. 1 shows it; at the end of its course with themoistening device at rest. Figs. 5 and 6 showthe pin engaging the paperstrip in two different positions.

Figs. 7 and 8 show a modified formof moistening arrangement in vertical; section Specification of Letters fatent. I 'Pathted-July 27., 1915 throfug'hthe water receptacle, in Fig. 7 with the moistening device pressed against the 1 paper strip and Fig.18with the moistening device swung downward.

The novel device forming thevobject of the present invention is suitably used in connection with a paper, perforator comprising'the customaryv perforating punches which stand under the control of springs 71. and which are mountedso as to be vertically movable in tened reinforcing strips 1, l have been brought fully into punching position, and

the frame 9, and are operated after the mois- I after the cutting device which is verticallymounted in'the main frame a has been actuated- The operationof these parts is efiected in the ordinary well known manner by meansof a lever mechanism 6, c, the tube 0 telescoping with a rod 6Z mounted vertically in the frame work a and in the base plate a and passing through the arms j, z. The arrangement for advancing the reinforcing strips 1, 1 which are passed through channels provided with slots 30 at boths'ides of'the lower frame 4,0? of the machine consist of a plate 5. sliding horizontally and guided by pins 26 working in slots 25 in'said plate, Fig. 2. The plate 5 is connected by means of tensionsprings 6 to a-cross bar 7 and is provided with a'slotted portion surrounding the guide rod on which the telescoping tube 0 works,to enable theplate 5 to slide freely. The sliding plate is, made of two parts, one on each side of the guide rod, which parts are provided with similarlyfdirected' inclined faces 11. Upon the downward movement ofan arm 14 carried bythe movable tube 0 rollers 12 rotatable in suit able bearings on said arms are pressed'upon the inclined surface 11,- and when the opera-f;

lever a movable abont b, a vertical down ward movement only can be imparted-to the rollers 12, they push the parts llan'd' the sliding plate 5 forward. The sliding plate 5 carries in addition pin shaped devices 9 each side, see Figs. 5 and 6, thesepins are provided with points 9 engaging the paper strip 1. Each pin 9 is located in a vertical casing 8 and is provided with a head 17, and each of them is controlledby a'spring 1Q. tending to force itdow'nward and is adapt :9 tion is effected by pressing down thehandle ed to be operated by means ofaplat'e 16', on

the frame of the device. p The guideplates16..areupwardlyiinclined in the direction of the forward motion and each of them is provided with a longitudinal slot 16 through which the shaft 9 of the pin passes and which engages said shaft just below the head 17 of the pin. By this arrangement upon the movement of the sliding plate 5 toward the front, the pin 9 is raised from the position shown in Fig. 5 into the position Fig. 6, against the action of the spring 10, whereupon a bent lever controlled by a spring 28, Fig. 2, and provided with a locking pawl 27, extends through the slotted opening 31 of the casing S and catches under the stepped portion be tween the pin shaft 9 and the pin point 9 keeping the pin in the position shown in Fig. 6 until upon the return movement of the sliding plate 5, under the pull of the spring 6, after the lever 0 has been released, one arm of the bent lever 27 comes into engagement with a projection 29, Fig. 2, on the side of the casing 61 thus releasing the pin 9, so that it again engages the paper strips 1 1 21, 21 are lever arms pivotally connected at 22 and located below the guides and sliding plate 5, on both sides of the frame work a. The arms 21 carry at their forward ends a transversely arranged water container 23, which at each end below the channels 30 for the strips has openings for the reception of absorbent wicks 2% for moistening the paper strips 1, 1 The lever arm 21, as will be seen in Fig. 1, is provided at its free end with a plate 20 adapted to move beneath the roller 20 which roller is carried by an arm 18 pivoted to the arm 14 so as to move in a vertical, plane and is kept in the position shown in Fig. 1 by the action of a spring 19.

The arm 1 1 by means of a clamping device 13 is clamped to the tube operated by the lever c.

The paper strips are fed from both sides from drums 2 located in the main frame and their tension is regulated by means of springs 3 pressing upon each of them.

From the slotted opening of each drum 2, each strip is passed over the bent-up end of the fixed guide, into the channel 30 in the frame-work to the place where the perforating and cutting operations are performed.

The operation of the foregoing described device is as follows: Upon the depression of the handle 0, the cutting means, the op eration of which need not be considered here, and the moistening device are operated almost simultaneously, the arm 18 kept in the vertical position by means of the spring 19 presses upon the end of the arm 21, thus raising said arm and pressing the wicks or sponges 24 in the water container momentarily against the paper strip 1. During its depression the arm 18 moves against the pressure of the spring 19 from the position shown in Fig. 3 into that shown in Fig. 4, so that the levers 21, 21 are released and the 0011- tainer 23, 2 1 under the action of gravity returns into its original position. lVhen the lever arm 0 is still further depressed,

the movement of the tube 0 caused thereby,

and the motion of the arm 14:, carries the rollers 12 mounted on the latter down onto the sloping surfaces 11 in connection with the sliding plate 5, pushing the plate 5 for ward until the rollers 12 come to the end of the sloping surface 11. The paper strips are drawn forward with the sliding plate 5 by the points 9 of the pins 9 engaging in the paper, until the engagement of the pins with the strips ceases, when the heads of the pins 9 enter the slots 16 of the sloping guides 16, disengaging the points and locking the pins by means of the locking device, in the manner already described. When the lever c is released and the rollers 12 return along the inclined surfaces 11, the sliding plate 5 is carried back into its initial position by the pull exerted by the spring 6 and the pins 9 9 released from the locking device 27 by the contact of the arm thereon with the projection 29. After being released, the pins 9 9 under the influence of the springs 10 are pressed down" ward and engage again with the paper strips 1, ready to push them forward.

As shown in Figs. 7 and 8 the moistening device carried by the lever mechanism 21, 22, 21 comprises a water container eX- tending transversely and having at each of its ends a perforated device inserted into or formed with the container which holds the absorbing material for moistening the gummed strips. Each of the parts 23 is provided with a small central tube, which is separated from the absorbent material in which is located a spring 23 normally projecting beyond the absorbent body 24, the spring being prevented from coming into actual contact with the absorbent body 261 by the surrounding tube. If the water container 23 is pressed against the gummed strengthening strip 1 through the action of the lever mechanism, on depressing the handle, the spring 23 is compressed, see Fig. 1. The strength of the spring is so calculated that a perforation of the paper strips or a displacement of the same out of the proper course is avoided. When the water container descends into its original position, after the release the lever mechanism 21, 21 and after the absorbent body 24 has momentarily been pressed into contact with the strip, the spring 23 is released and its upper coil presses against the gummed strip, so that the latter is set free and can be moved forward without impediment, even when the absorbent material through wear and tear has become sticky.
