FEED MECHANISM FOR CUTTING-MACHINES.

hoeveel-i.

To all whom t may concern.'

Be it known that we, JOHN MCCOY and @Terrien A. Corminarnn, citizens of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful lmprovements in Feed Mechanism for Cutting llflachines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention takes a strip of flexible material from a roll, delivers it in plaits or folds onto a belt whereon it is allowed to accumulate and by which it is carried forward, then passes it through a tension device and next a driving mechanism by which it is fed to and through. a treating machine, beyond which it passes through a drawing mechanism and is delivered onto a second belt in plaits or folds, and from the latter it is carried to a contiguous rack on which the linished product is reeled or rolled with an interposed strip or lining.

'in the practical application of the invention and in the embodiment set forth in the following specification, the strip is of paper and the finished product is intended to be a border for wall paper. lVhile the treating machine may include mechanism for printing, embossing, or otherwise ornamenting the strip, we have herein shown and described it as a cutting machine for trimming one edoe of the strip in an irregular manner so as to produce a frieze along the same, although it will be understood that the cutting mechanism mighteasily be duplicated so as to produce a friese along each edge of the strip or the treating mechanism might be amplified so as to produce embossed paper with one or both edges irregular, and perhaps also print it in colors and otherwise ornament it. lt is well known to those engaged in this business that wall paper is aiuto fragile, easily torn and wrinkled, and often becomes stretched or blistered even while it is stored in a roll.

lhe present machine is designed. to take ont such irregularities and feed the paper smooth to the treating machine and there lio-ld it under tension, but between this machine and the roll we interpose feed mechanism so that a, quantity of the strip is drawn from the roll and delivered in plaits or folds onto a slow-moving belt by which it is car- Speccation of Letters Patent.

ried toward the treating machine and from which belt it is taken up b v the tension mechanism and delivered positively to said machine. llfhe interposition of this detail avoids the tearing of the paper as often occurs when it is drawn forcibly from the roll and fed directly to the treating machine. Again, after leaving the latter, we prefer to convey the paper in plaits or folds along a second slow-moving apron or belt toward the rack upon which it is reeled or rolled in its finished condition, and the interposition of this detail prevents the tearing of the linished product which might occur if the operator who manipulates this reel should turn it more rapidly than the finished product is delivered from the treating machine.

With this general statement of the various objects accomplished by the present involition, the same may be said to consist in the mechanism hereinafter more fully described and claimed, and as shown in the drawings wherein Figure l is a front elevation, Fig. 2 a rear elevation, Fig. 3 a central longitudinal section, and Fig. 4 a plan view of this machine complete. The remaining views are on a larger scale. Fig. 5 is a front eleifation of the cutting machine and the cen tral portion of the entire mechanism, and Fig. G is a vertical longitudinal section; Fig. 7 a rear elevation, and Fig. S a plan view of the same parts. Fig. 9 is an enlarged side elevation of the feeding mechanism for drawing the strip from the roll at the inlet end of the machine, and Fig. l0 is a central vertical sectional view through this portion of the machine. Fig. 1l is a vertical cross section through the machine, looking in the direction of the arrow 1l at the right of Fig. 9. Fig. 12 is an enlarged side elevation, partly in section, showing the guide roller and the mechanism for adjusting it. rig. 13 is a plan view of a portion of the strip of wall paper, the left hand partof the view showing it before and the right hand part of the view after the cut is made.

Broadly speaking this machine comprises feeding mechanism at its left hand end for drawing the paper from the roll, an endless belt conveying the paper thence to the treating machine C which stands at the center of the entire piece of machinery, a second endless belt carrying the treated paper away from such machine, means for feeding a continuous strip or lining underneath the finished product, and a contiguous rack (either forming part of or detached from the main framework) on which the product and its lining are reeled or rolled.

No novelty is claimed for the treating machine herein broadly designated by the letter C, and it need not be described further than to say that if it be a cutter it will include a platen P, a cutting die D, and a vertically movable head H carrying the die and driven from a suitable source of power;

The uncut paper is shown in a roll 1 at the left end of the frame 2 of this machine, its shaft 3 being mounted in bearings et as best seen in Figs. 9 and 10, although we do not limit ourselves to this specific manner of mounting the roll. From the latter the paper is led to the feeding mechanism which consists of a drum 5 mounted in bearings 6 on the frame near the top of the same, and a gravity roll 7 whose trunnions 8 are mounted loosely in slotted bearings 9, which latter are carried by brackets 1G on the frame 2. On the brackets 10 is adjustably supported a cross bar 11 (as by means of slots 12 and set screws 18) and from said bar depends a curtain preferably composed of some rather heavy fabric such as burlap, carpet, or canvas, and indicated by the reference numeral 14. The lower edge of this curtain hangs adjacent to and over a fixed guide 15 inclined downward from the drum 5 as best seen in Fig. 9, and the paper after passing over said drum and under the gravity roll 7 will strike the curtain and by it be automatically plaited or folded onto the guide, the rather loose plaits or folds assuming an oblique position as shown in Figs. 9 and 10. The adjustment of the cross bar 11 is obviously for the purpose of setting the curtain 111 so that the plaits or folds will certainly be made, and their length will be such as the character of the paper requires.

r[he numeral 16 designates an endless belt moving over rollers 17 and 1S journaled in the frame, the shaft of the roller 1S having on one extremity a sprocket wheel 19 connected by a chain belt 20 with a similar sprocket wheel 21 at the rear end of the shaft of the drum o, and a second sprocket wheel Q9, on the same roller shaft is connected by another chain belt 23 with other endless belt 72 to be described herein after. Thus the plaited paper passes ofT the guide and out from under the curtain and is delivered onto and carried forward by the belt 16 so that its plaits or folds are not interrupted and a considerable quantity of paper accumulates on the upper side of the belt which travels over a board Q4 fixed in the frame 2 so that it shall not sag.

The guide roller (see Fig. 12) over which the paper passes next is designated by the numeral 30, has radial flanges 81 at its eX- tremities, and is mounted loosely on a shaft set screw 38 or other device may be tightened up to hold the shaft from movement. it this time the paper has not been cut and therefore it has two straight edges, and the flanges 31 are preferably spaced sufficiently far apart to rest against said edges nicely. Coacting with said roller is a second curtain -10 hanging from a cross bar 41 whose eX- tremities are mounted in links 412 upstanding from the outer ends of the brackets 36 to which they are pivotally connected as by studs and nuts 1S so that the links may be adjusted to adjust the position of the curtain. The latter hangs by preference about as seen in Figs. 5 and 6, and its lower edge serves as a scraper to take out the folds or plaits of the paper before the latter passes to the guide roller.

Adjacent the roller and scraper last above described is located what might, be termed the tension device, and by preference the same is mounted upon the saine brackets 3G and consists of a series of bearings L.t6 in which are journaled rollers 4'?, 4S and 49, and the paper after passing over the guide roller is led under the roller 47, over the roller a8 and then under the roller Lt9 so that a certain amount of tension is applied to the paper strip.

The driving drum 50 referred to above may well be hollow with trunnions 51 mounted in bearings in the same brackets 36. Adjacent said bearings are others in which are mounted the trunnions 58 of two ironing rollers 54, one by preference disposed above the drum and the other about 600 forward of the point upon which the uppermost roller rests; and the paper after passing through the tension device passes under these rollers. rfhe rearmost trunnion 51 of the drum 50 carries a gear 50 a little smaller than the drum, and the rearmost trunnions of the rollers 54; carry pinions 5st a little larger than the rollers and meshing with said gear, all as best seen in Fig. 7. This construction causes the face of the rollers to move somewhat slower than the face of the drum, and in doing so they stroke or iron out any kinks or wrinkles that may remain in the paper after passing through the tension device.

The treating machine or cutter C has already been explained as far as we deem necessary. rlhe paper after passing through the driving mechanism is led across the platen P of this cutting machine and preferably under guide fingers who-se shanks are adjustably held in brackets 56 carried by the framework of the cutter, and whose extremities or points are directed downward toward the platen but elevated slightly above the same. rlhe paper when it is printed or embossed or otherwise ornamented may be provided with perforations or indicating marks 57 (see Fig. 15) which are spaced apart at intervals equal to the length of the ligure that is repeated thereon, and it is intended that the points 55 shall be so set that when they both register with a pair of said marks 57, the cutting die D can be brought down to trim the waste along the edge of the paper as shown at the right hand of Fig. 4i. Thereafter the drawing mechanism must be actuated to move the paper along for another interval which will be the length of one or more figures such as are repeated in the design of the paper, in a manner which will be well understood by the manufacturer of wall paper and the like. lt will be understood, also, that when paper of a different pattern or design is to be trimmed, the die D in the cutter C must be changed and the fingers and their points reset to correspond.

rlhe drawing mechanism is disposed to the right of the cutter as seen in Fig. l, and is best illustrated in detail in Figs. 5 and 6. By preference its construction follows that of the driving mechanism at the left side of the cutter, described above, and therefore we need not repeat its details. It will be seen from Fig. 7, however, that the relative sizes of the gear 68 and the pinions 69 with respect to the drum and rollers at this side of the cutter, are reversed from the relative sizes of the gear 50 and pinions 54C described above. rlhe result is that the faces of the rolls in the drawing mechanism move a little faster than the face of the drum so that the paper is drawn straight across the platen of the machine and cannot shift laterally. Power is applied by means of a hand wheel 60 journaled in a bracket 6l on the frame of the cutter and carrying two sprocket wheels 62 and G3 on its shaft, one of said wheels being` connected by a chain belt G4 with a sprocket pinion 65 fast on the front trunnion of the driving drum 50, and the other being connected by a belt 66 with a similar sprocket pinion 67 fast on the front trunnion of the drum 68 of the drawing mechanism. By preference the pinions and 67 are not of the same size; that is to say, the former will have about twenty teeth and the latter about eighteen, so that when the power wheel 60 is rotated the drum 68 and rollers 69 of the drawing mechanism are turned to a slightly greater degree than the drum and rollers of the driving mechanism, and the result is that the paper is placed under some tension where it passes across the platen P of the cutting machine. Yet

the paper will not be torn under the tension set up, because it will slip through the drawing mechanism before it will tear, and the slipping occurs at this side of the cutter C because of the stronger grasp on the paper at the other side of said cutter which is aorded by the tension device. Frein the rear trunnion 51 of the drum 50 power is communicated as by a belt 70 to the rear trunnion of the drum 5 of the feeding mechanism, and therefore when the operator turns the hand wheel 60 and moves the paper forward over the platen for a certain distance, he simultaneously causes the rotation of the feeding drum 5 to draw an equal length of paper oft' of the roll l. This drum being connected' with the belt 16 causes its feed forward toward the cutter, and the parts are so proportioned that the feed of this belt will carry forward as much of the plaited paper as is necessary and yet only so much, in order that the plaits or folds may remain stacked upon the belt 1G as shown at the left of Fig. l.

Experience has taught us the value of having at all times quite a considerable supply of loose material to work on, rather than drawing the strips direct from the roll which is large and heavy and whose sudden starting and stopping would throw the strip of paper out of the proper alinement or possibly stretch or tear it by accident. Substantially the same reason prevails for the construction next to be described, whereby the belt 1G is practically duplicated at the other side of the cutting machine C. In addition, as will subsequently appear herein, the finished product is rolled or reeled at a remote point and by another operator; and, lest he should roll it up too rapidly and tear or injure it, a second slowanoving belt is provided so that he shall always have quite a supply of the loose material to work on. [it the right end of the machine is a second endless belt .71 moving over rollers 72 and T3 and its upper stretch sliding over a board 74, much the same as the belt already described; and at the inner end of said board a guide 75 rises obliquely therefrom toward the drum G8, and another hanging curtain is provided as seen at the right of Figs. 5 and G and for the same purpose as the first curtain let. rlherefore the paper after having1 been cut passes over the drum GS and under its presser rollers 65), and is again subjected to the plaiting process and delivered on the rear belt 71 in folds or plaits as seen at the right of Fig. l.

At the delivery end of the machine the structure is slightly different from that at the inlet end thereof. Here the paper after leaving the belt 7l (which is preferably located at a considerably higher level than the belt '1.6) passes between two upright guide rollers mounted on a cross bar 81 having 'pal a slot S2 which is adjustably supported by a set screw 83 in the frame 2; and from this point the trimmed or finished paper is lcd to a stand or rack R where it is rolled or reeled as at S5 by means of a crank handle S6, or by power if desired, although .we prefer the construction illustrated. ln order that the tine points and projections of the grille or frieze may not become injured or turned under, we find it wise to mount a. roll 8T of coarse paper in brackets 88 on the frame 2 at its delivery end, and lead this paper upward as at 89 under the wall paper being nished and wind it onto the roll S5 therewith, so that the lining paper 89 may be interposed between the convolutions of the wall paper as it is linished. here may be several pairs of the brackets 88 as indicated in the drawings, and several varieties of the lining paper S9 as shown` and in some instances it may be desirable to put several thicknesses of the same and perhaps several widths of the same onto the roll S5 with the finished product.

Thus it will be seen that we have produced a machine .which takes the wall paper from a roll l, passes it through feeding mechanism at the inlet end of the frame, plaits or folds it adjacent this point and delivers it onto a slow-moving belt i6, carries it thereby to the guide roller whence it is passed through the tension device, and feeds it to and through a cutting machine C. The latter is driven by any suitable source of power, but is controlled by a treadle or pedal T so that the operator may cause the die D to descend upon its platen at intervals when the marks in the paper underlie the points and this of course he will not do until he has adjusted the paper exactly in proper position. After the paper has been cut it is drawn forward or to the right out of the cutter C by means of the drawing mechanism, plaited or folded again and delivered onto a second endless belt, and carried thence to and delivered over the right or outlet end of the machine as shown. Here the linished product is produced and the waste strip .is doubtless carried to one side and torn off from time to time; and beneath this end of the machine are mounted rolls of lining paper so that as the finished product is carried to the rack R- and wound into a roll, the lining is wound with it and the fine points of the grille or frieze are prevented from injury.

lWe do not confine ourselves to the details of construction, but have amplified the same for purposes of illustration.
