SPECIFICATION formingpart of Letters Patent No. 581,015, dated April 20, 1897.
Application filed July 6,1896. Serial No. 598,227. (No model.) 7
To all whom it may concerni Be it known that we, ABRAHAM L. ADAMS and GEORGE E. HAwEs, citizens of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Machines for Automatically Cut-tin g, Folding, and \Vinding Strips of Flexible Material; and We do hereby 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.
Our invention relates to certain improvements in machines for automatically cut-tin g, folding, and winding strips of flexible material so that such strips may be available for use in the form of spools; and our invention vconsists in the details of construction and in the operation of various instrumentalities such as will be hereinafter fully set forth, and then specifically designated by the claims.
In the accompanying drawings, which form a part of this application, Figure 1 isa plan view of our newly-invented machine; Fig. 2, a side elevation; Fig. 3, a section at the line a a of Fig. 1; Fig. 4, a section at the line b b of Fig. 3; Fig. 5, a section at the line 0 c of Fig. 3; Fig. 6, a section at the line (I d of Fig. 1; Fig. 7, a detail sectional elevation, on an enlarged scale, showing the operation of the rollers which effect the creasing, folding, and ironing functions; Fig. 8, a sectional elevation similar to Fig. 3, but showing a modification of our invention in which the ironingroller is dispensed with; and Fig. 9, a sectheless we do not wish to he confined to such association, since our invention is broad enough to include each one of such mechanisms separately and distinctly. In other words, each mechanism, by the elimination of the other two mechanisms, is enabled to perform its individual function and constitutes a machine in itself producing a useful result. These three mechanisms to which we have referred are, first, the cutting orslitting machine, by means of which the strips are cut from a solid width of material; second, the folding mechanism, whereby the lateral edges of the strips are folded over upon the body of the strip; third, the winding mechanism, by means of which the finished strips are wound upon spools.
For a better understanding of our invention we will describe these several mechanisms consecutively, but we will first call attention to the general form of the machine and its adaptation to such mechanisms.
1 is the frame of the machine, \vhichis supported in any usual manner, as by legs 2, and 3 is the bed or table.
4 is the power-shaft, power-pulley 5.
The cutting mechanism comprises two rolls 6 7, journaled within the frame of the machine one above the other, each roll carrying a series of cutter-disks 8 9, which respectively engage each other after the manner of a pair of shears. These disks are separated by a space equal to the full Width desired of the strips, and rigid with said rolls 6 7 are intermeshing spur-gears 1O 11, one of which gears also meshes with a gear 12, carried by the power-shaft 4, so that it will be clear that the proper revolution of the cutter-rolls will be effected directly from the power-shaft.
A piece of fabric or othersuitable material of the desired width being placed upon the table 3 and led between the rolls 6 7, it will be manifest that as this fabric passes between the rolls it will be cut or slitted into a gang of strips, which latter are then engaged by the mechanisms for creasing, folding, and ironingsuch strips, which mechanisms we will now describe.
13 14 are rolls journaled within the frame which carries the of the machine and carrying intermeshing spur-gears 15 16, one of which latter is also engaged by the gear 12 on the power-shaft. The roll 13 has in its periphery a series of annular grooves 17, whose width is equal to the width of the folded strip, and the roll 1t earries a series of peripheral collars 18, which fit snugly within said grooves.
19 is the ironing-roller, which is journalcd within a frame 20, which latter at its lower end is pivoted around the shaft of the roller 14, while its outer extrcmitycarries a resilient plug 21, which rests upon an adjusting-screw 22, driven through an car 23, rising from the frame of the machine. This ironii'ig-roller is beyond the rolls 13 11- and is elevated so that its upper circumference is considerably above the lower circumference of the roll 13, and such ironing-roller carries a gear 25, which meshes with the gear 15" and also carries a series of peripheral collars 2t of such width as to fit snugly within the grooves of the roller 13.
As the strips already cut, in the manner hereinbeforc set forth, pass between the rollers 13 11- the collars on the roller 11- will force the strips within the grooves of the roller 13, thereby causing the edges to be creased, so as to lie flat against the side walls of the grooves, and the tension on the creased strips as the latter are deflected upward around the bottoms of the grooves will draw the creased edges down flat against the bodies of the strips, and the roller 10 will then act against these folded edges to firmly iron them into place. The pressure of the ironing-roller may be regulated by the adjusting-screw 32.
It will be observed that there is a space between the points of contact which the rollers l-t 19 have with the roller 13, and the object of this of course is to enable the creased edges of the strip to be drawn down flat against the body of the strip by the upward deflection of the latter around the roller 13, so that said edges may be properly disposed before they are brought in contact with the ironing-roll, and right here in this connection we would say that this manner of drawing down the edges of the strips preparatory to ironing is a very important feature of ourinvention, since we are enabled thereby to dispense with any special appliance for performing the folding operation.
The folded and finished strips are passed over the top of the ironing-roller to the winding mechanism, a description of which latter we will now give.
26 is a guide-roller journaled in the frame of the machine, and having in its periphery a series of grooves 27just wide enough to contain the folded strips.
28 is a spindle journaled within the upper end of a frame 99, the lower end of which latter is pivoted around the power-shaft i On this spindle are keyed a series of spools 30, corresponding in number to the number of strips, and each spool is slotted in its periphery, as seen at 31, within which slotted portions the extremities of the strips are forced for the purpose of secu ring the latter during the winding operation.
The folded strips are passed within the grooves 27 and are secured to the spools, and as the strips are wound on said spools the coiled-up portions of said strips will extend within said grooves and will be supported by the bottoms of the latter. As the strip-rolls increase in diameter during the winding operation the contact between the strip-rolls and the guide-roller will be constant, owing to the fact that the frame 2!) will be gradually elevated by reason of the gradually-increasing distance between the spindle 28 and the guide-roller. he side walls of the grooves 37 cause the strips to be wound in vertical planes, while the contact between the stripeoils and the guide-roller causes the winding to be effected tightly. Upon the extreme outer end of the frame 99 a weight 32 is placed to increase the frictional contact be tween the guide-roller and the strip-coils, and this weight may be varied as the oceasion demands or it may be dispensed with altogether, if desired.
The spindle 28 ismade in two sections, one of which terminates in a socket 3 3, while the other section is bifurcated, as shown at 3st, and fixed within said socket, a pin 35 being driven laterally through said socket and within said fork, whereby the two sections of the spindle are secured together as to rotary motion, while at the same time the section which carries the spools may be readily withdrawn by grasping the handle 36 for the purpose of removing the spools.
Of course it will be clear that as the diameters of the strip-rolls increase the revolution of such rolls would tend to draw a longer length of strip, and we therefore belt up the spindle to the power-pulley, making use of frictional devices of very ordinary construction, so that the full benefit of the drivingbelt cannot be exerted to revolve the spindle. lVithout going into any details of explanation of such very ordinary mechanical expedient we will merely say that the socketsection of the spindle carries a shoulder-collar 37, while around such section is a loose disk 3.38. which abuts against said collar. A collar 39 is splined on said section, so as to be capable of a movement lengthwise thereof, and interposed between this collar and disk 38 is a leather washer 10, a nut 4-1. being driven on the extreme end of said section and a coil-spring 12 being interposed between said nut and collar 39, so that when the nut is driven inward the disk 08 will be bound between the shoulder 37 and collar 3.), the friction between such parts being sufficient to cause the spindle to be revolved when power is applied to the disk 38. A belt is run from the power-pulley around said disk, and when the tendency of the winding-spools is to take up a greater length of strip than is out and folded the disk 38 will simply slip around the collar 37 without efiecting a correspond ing revolution of the spindle.
The surfaces of the various portions of the several rollers which come in contact with the strips may be serrated or roughened, if desired, in order to obtain a better grip on the strips, and in the instance of certain materials of which the strips are composed this may be deemed necessary; but we do not desire to be limited in this respect, as this is a Y precautionary measure rather than a necessary adjunct of our invention.
There is a great difference between fabrics and other materials of which the strips are composed, and some of these will become cockled or distorted more readily than others,
and we have therefore provided certain devices which we will now describe and which greatly assist in properly delivering and guiding the cloth during the various operations hereinbefore set forth.
Resting immediately upon the table in front of the cu ttin g-rollersis what we term a guideplate 43, upon whose upper surface are two series of ribs 44: 45, one of such series being on one side of a vertical plane which intersects the cutting-rollers crosswise at their middle portions and the other series of such ribs being on the opposite side of such plane. These two series of ribs are each inclined from their outer extremities inwardly toward said plane and at the same angle thereto, and the cloth as it is delivered to the cutting-rollers rests immediately upon said guide plate. Should it be discovered that the cloth was being fed out of true or in a direction a little to one side, the operator simply places his hand upon the cloth and presses it lightly against the ribs of the guide-plate, which incline in the direction opposite to that in which the cloth is bein gimproperly shifted, and this will immediately correct the error, and by practice an operator may readily correct any inaccuracy in the feeding of the cloth.
Rising from the table immediately in the rear of the creasing-rollers and at the extreme opposite sides of such table are twin spindles 46, and between these spindles is a vertical plate 47, of metal, which rests by its gravity like a straight-edge immediately upon such table. The strips pass from the cutters im mediately beneath this plate, and any cockling or twisting of such strips is smoothed out by the plate prior to the delivery of the strips to the creasing, folding, and ironing rollers.
We are enabled to obtain the best results by making the effective diameters of all the positively-moving rollers the same and by so gearing them that their speeds will likewise be the same, for by so doing there can be no dragging of the strips or of the cloth through any of the rollers and the cloth or other material cannot possibly become distorted.
It will be manifest that some of the mechanisms of our improved machine may be changed and others may be entirely omitted without departing from the spirit of our invention, to some of which changes and omissions we will now call attention.
The guide-roller is not at all necessary to the manufacture of the strips, and, moreover, while a most excellent contrivance, need not be used at all times, especially in instances where the spools themselves have flanged sides. The ironing-roller, while it is really necessary in the instance of most fabrics, can
be entirely dispensed with at times, especially when the strips can remain in coiled form before using a sufficient length of time to enable the folded portions to set.
In Fig. 8 we have shown a modification of our improvement in which the ironing and guide rollers are entirely dispensed with and the strip led farther around the upper creasing-roll and upwardly to the winding-spool, which latter in this instanceis supported almost immediately above such roll in order to allow the strip to have this additional lap around the latter.
. Some strips are used without folded edges, and heretofore these strips have been cut and wound upon spools in a very crude and imperfect manner, but our invention naturally suggests a very practical and effective way of cutting and winding such strips, it being necessary merely to omit the rollers which effect the creasing, folding, and ironing of the edges. lVe have therefore shown in Fig. 9 a modification of ourimproved machine in which the guide-roller is indispensable in connection with the winding-spool. Referring to this Fig. 9, we would say that the construction, assembly, and operation of all the parts shown are precisely the same as hereinbefore set forth, with the exception that the guide-roller carries a pulley 48 and the power- IOC shaft a pulley 419, which pulleys are connected by belt 50, so that it will be clear that a positive revolution is imparted to the guide-roller directly from the power-shaft.
As hereinbefore set forth, the winding-roll has a tendency to drag the strips through the cutting-rollers, and this tendency is of course resisted in our construction above described by the creasing and ironing rollers, which maintain quite a bite upon the strips. In the present instance the tendency of the winding-spools to revolve too fast is checked by the uniformly-speeded guide -roller, which latter, by the way, moves at precisely the same rate of speed as do the cutter-rollers.
be stationary and the strips may be pulled therethrough by the winding devices, and we therefore do not wish to be limited in this respect.
Having thus described ourinvention, what we claim as new, and desire to secure by Let ters Patent, is
1.
