LYNCHBURG, VIRGINIA.

PAPER-FEEDER.

SPECIFICATION forming part of Letters Patent No. 765,316, dated July 19, 1904. Application filed November 24, 1902. Serial No. 132,569. (No model.)

To all whom, it may concern:

Be it known that I, JAMES A. KEYES, a citizen of the United States, and a resident of New York city, in the borough of Manhattan, county and State of New York, have invented certain new and useful Improvements in Paper- Feeders, of which the following is a specification, taken in connection with the accompanying drawings, which form a part of the same.

This invention relates to paper-feeders, and relates especially to apparatus for feeding paper froma continuous strip or roll and for accurately severing this strip into sheets.

In the drawings, in which the same reference character refers to similar parts in the several figures, Figure l is a sectional view showing an embodiment of this invention, taken substantially on the line 1 1 of Fig. 3. Fig. 2 is a detail perspective view showing parts of the same. Fig. 3 is a partial sectional view taken substantially on the line 3 3 of Fig. l. Fig. 4 is a detail showing the perforated paper strip.

In the embodiment of the invention shown in the drawings a frame A is preferably employed formed with bearings for the various shafts for the moving' parts of the apparatus. In the top of this frame there is mounted in the usual way the paper-reel E3, on which a quantity of paper in the form of a continuous perforated stripfE is wound to be fed by the feeder as desired. In order to relieve to some extent the strain on the paper strip, an auxiliary feed may be employed adjacent the reel E3. In the drawings an auxiliary feed comprising a feed-segment Eit is shown, this segment cooperating with the idler E5. This idler, as indicated. is formed with flanges F6 on either end of the same and is geared by the meshing gears E2 F3 to be operated from the feed-segment. The paper strip is of course engaged between the idler and the segment and is intermittently fed forward to the desired extent, thus relieving the strain on the paper strip to a very considerable extent.

As f indicated, the idler Ej is used, over whichy the strip passes to the intermittentlygripping feeder. This feeder operates to positively grip the strip of paper and to feed it forward. The grip of the feeder upon the strip is, however, released at certain times, so as to allow for the operation of the positive aliner, which cooperates with the paper strip and secures the exact alinement of the same as it is fed forward. gripping feeder is preferably composed of two feed-rolls B and C. These feed-rolls cooperate, so as to -positively grip the paper between them; but one of the feed-rolls is formed with a depression C3, which releases the paper strip when the rolls reach the po- Vsition indicated in Fig. 2, and the paper strip can then pass freely between the rolls and can be readily adjusted under the action of the aliner.

As indicated in the drawings, the paper strip E is formed 'with the series of perforations or holes E2, which are regularly spaced along the strip and which enable lthe strip to be accurately alined, so that it may, if desired, be

severed by appropriate cutting devicesexactly along the intended lines of severence E. The perforated strip is in this way severed accurately into the separate sheets, which are fed forward to be used as desired. This of course is of special utility where'the paper strip is printed, each sheet having appropriate printed matter upon it. The alining' means cooperates with the holes or perforations E2 and acts when the intermittently-gripping feeder is in released position, as indicated in Fig. 2. This aliner preferably comprises alining members to coperate with the perforations E2 in the paper strip and to accurately adjust the position of the paper strip from time to time. In the drawings each alining member B3 is indicated as mounted in the feedroll B, a suitable retracting-spring B" being employed which acts upon the collar B* on the alining pin or member to normally retract the point B2 beneath the working surface of the roll. The alining member is thrown out into operative position by the pin B, secured tothe same, which cooperates with the alining-cam This cam, as 1s indicated in Fig. 3, is se- The intermittentlycured to the frame adjacent the shaft B, and

the pin B2 is thereby raised beyond the surface of the roll B at each revolution, is forced through the hole E2 in the paper strip, and positively alines the paper strip at this time. The end B2 of the alining member cooperates with the hole C2 in the other feed-roll, and it will be seen that as soon as the alining members have operated the earns cease to protrude them, and they are withdrawn beneath the surface of the feed-roll in which they are mounted.

The presser D is preferably employed in conjunction with the aliner, two of these pressers D being shown secured to the presser-rod D. The operative ends of these pressers are preferably slotted, so that the points B2 of the alining members may project through them, as indicated in Fig. 2. The pressers may be held in proper engagement with the paper Strip by the presser-spring D", which operates on the crank D3, secured to the presser-rod. The latch D5 is preferably connected with the crank and is formed with the notches DS, so that when the pressers are raised the latch is forced down under the action of the light spring D6 to latch over the pin D7 and hold the pressers in raised position. The pin D9 may be employed, if desired, to limit the' downward movement of the pressers. The presser preferably exerts a slight tension upon the paper strip, holding the strip against the feedroll Band alsoserves to hold the strip down, so that the alining members B2 properly engage the perforations E2 in the strip. This slight tension exerted by the pressers prevents any slipping of the paper strip which might otherwise occur whenl the grip of the `of the cutter, so as to shield the cutting edge of the same in the manner illustrated in Fig. 2. A cooperating severing-slotis formed between the blocks C4, mounted in the roll C. The severing mechanism operates to sever the paper strip when in the position indicated in Fig. 1, and each severed blank passes down the operations of the feeder being properly regulated in any case. It -will be noted also that the time at which the auxiliary feed operates may be suitably adjusted by adjusting the relative positions of the gears F2 and F. This feeder withdraws from time to time a portion of thc continuous strip E from the reel by the auxiliary feed described, so that a certain amount of slack is supplied to the feed-rolls B and C when in the position indicated in Fig. 1. As the feed-rolls revolve in the direction indicated by the arrows the alining members are protruded by the cams indicated, so that the ends B2 of these alining members project through the holes or perforations E2 in the paper strip and positively aline the strip operating in connection with the pressers. At this time the feed-rolls are in the released position, (indicated in Fig. 2, so that any slight adjustment of the paper strip is readily effected by the aliner. The feedrolls on their continued rotation positively grip the paper strip between them, feed it forward, and finally the severing mechanism operates to cut off a blank from the end of the paper strip. l

It is of course understood by those' familiar with this art that many changes in the form and proportions of parts may be made. Furthermore, parts of this apparatus may be omitted, if desired, and parts may be used in connection with other devices without departing from the spirit of this invention. I do not therefore desire to be limited to the disclosure which has been made in this case; but

What I claim as new, and what I desire to secure by Letters Patent, is set forth in the appended claims:
