'CLOTH-CUTTING- MACHINE.

Specification of Letters Patent.

Patented Oct. 9, 1917.

Application led August 5, 1916. Serial No. 113,242.

To all whom t may concern:

Be it known that I, OSCAR I. J UDELSHON, a citizen of the United States, and resident of New York city, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Cloth-Cutting Machines, of which the following is a specification.

The object of my invention is to provide means to cut rolls of cloth, paper and analogous webs into spools or reels of desired width, such rolls usually being wound upon hollow cores, such as upon a paper or pasteboard tube.

My invention comprises novel details of improvement and combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein,

Figure 1 is a partly broken plan view of a machine embodying my invention;

Fig. 1a is a sectional detail of part of the means for rotating thev roll to be "cut into spools;

Fig. 2 is a partly broken side view of a portion of Fig. 1; Y

Fig. 3 is a section on the

line

3, 3, in Fig. 2

Fig. 4 is an end view, looking at the right hand side of Fig. 1;

Fig. 5 is an enlarged sectional detail through the roll rotating means;

Fig. 6 is an enlarged detail section illustrating the cutter during operation of cutting the roll;

Fig. 7 is an enlarged detail plan view, partly in section, illustrating means for adjusting the cutter grinding wheel;

Fig. 8 is a section on the

line

8, 8, in Fig. 7; and Fig. 9 is a detail section illustrating means for supporting a grinder adjacent the cutter hereinafter referred to.

1n the accompanying drawings the numeral 1 indicates a suitable frame, upon which spaced uprights or brackets 2 are secured, in which uprights shaft 3 is supported to rotate in suitable bearings, and .-1 non-rotative rod 4 parallel with shaft 3 is secured to said uprights. Above rod 4 a non-rotative rod 5is supported by the uprights 2, adapted to support a roll 6 of cloth or other article to be severed. Rod 5 may be secured in an opening or bearing in one of 'the uprights 2, by a set screw 7 (Fig. 5), and

at the opposite end of said rod is a supporting arm 8 having an opening or recess re ceiving the adjacent end of the rod. Arm 8 is slidably mounted upon rod 4 and a bolt or screw 9 is adapted to detachably retain arm 8 in set position on the adjacent upright or bracket 2. The arrangement is such that arm 8 may be released from bolt or stud 9 to permit the arm to be slid outwardly along rod 4 to release rod 5, whereupon said arm may be swung to one side to permit the application of roll 6 to or its removal from rod 5. When arm 8 is secured in position to support rod 5 the latter will be held from movement in any direction while the roll 6 rotates on said rod. The roll 6 is illustrated of a character having a tubular core 6a, as of paper, pasteboard or the like, upon which the fabric web is wound. Means are provided for rotating roll 6 around rod 5 when the roll is to be cut. For such purpose I have shown a sleeve 10 mounted to rotate upon rod 5 and provided with a head 10il provided with pins 16 adapted to enter the material of roll 6. Said pins are shown carried on arm 17 projecting from slides 18 located in grooves 10b in the adjacent face of head 10a, screws 19 threaded in said head serving to jam against slides 18 to retain them in set position on the head. By this means the slides may be adjusted radially to provide for rolls 6 of different diameter, the pins ma)7 be entered in the rolls and the slides 18 set tight in the head, whereby when sleeve 10 is rotated the roll will be correspondingly rotated thereby on rod 5. Sleeve 10is shown provided with a sprocket wheel 11 receiving chain 12 from a sprocket wheel 13 secured on shaft 3, which shaft is shown provided with fast and

loose pulleys

14, 15 adapted to receive a belt for rotating said shaft, sleeve 10 and the roll.

ln order to cut the rolls transversely at suitable distances therealong, to produce from the rolls spools or reels of suitable width, l provide a rotary cutter 20, suitably spaced from rod 5 and shown located at right langles thereto, the cutter being adapted to move toward the reel and rod and away therefrom. Said cutter mounted upon shaft 21 which .is journaled in bearings on an arm 22 that is mounted to rock upon shaft 3. Cutter 20 may be detachably held upon shaft 21 by means of is shown Y a nut serving to clamp the cutter against a stop or fla-nge on the shaft in an ordinary manner. The means l have shown to rotate cutter comprise a sprocket wheel 23 secured on shaft 2l and receiving a chain 24 passing from a sprocket wheel slidably mounted on shaft 3, said shaft 3 being shown provided with a longitudinal groove 3a receiving a key or stud projecting from the sprocket wheel, whereby the cutter may be rotated in its different positions of adjustment along shaft 3 relatively to roll 6. By means of a suitably shaped arm 26 secured to arm 22, the latter may be rocked to cause the cutter to approach and recede from the roll. The cutter is normally retained retracted from roll 6, for which purposel have shown a spring 27 connecting arm 22 with a member on a slide or table 28. '.llo limit .the rearward movement of arm 22 by spring 27 l provide a stop 29, shown in the form of a screw working in a threaded opening in an upright 30 on slide l or table 28, a nut 3l on said screw serving to retain the same in set position. To limit the movement of the cutter toward rod 5 l provide a stop 32, shown in the form of a screw working in a threaded 'opening in an upright 33 on said slide or table. The screw may be held in set position by a nut 34. The stop-

screws

29 and 32 are adapted to be adjusted to accommodate cutters of different diameters so that when a cutter is worn away by sharpening or grinding, stopscrew 32 may be set to permit the cutting edge to approach nearer to rod 5 as may be required to cut the roll and its tube 6a. Slide or table 28 is adjustable along the frame below roll 6, and is provided with an opening receiving arm 22 whereby the latter will be moved along said shaft with the slide or table. Said slide or table is shown slidably receiving shaft 3 and rod 4, whereby'the table is guided, and in order to relieve shaft 3 from the weight of the table and its parts I have shown said table provided with a forked arm 36 in which a roller is journaled and adapted to travel upon a plate ci rail 37 secured on frame 1. In order to move the table and 'cutter along the frame relative to roll 6 as desired, l provide a hand wheel 38 journaled upon the frame, as upon a. stud or shaft 39 secured thereon. To said wheel is connected a sprocket wheel 40 engaging a chain 4l that is stretched along the-frame between the end brackets 2, as by securing the ends of the chain to suitable stops 42 on said brackets, as by means of screws 43. The foregoing provides a simple and eii'icient means for enabling adjustment of the table and cutter along the frame in either direction as desired, although other suitable means @for .such purpose may be provided.

Since the cutter 20 may become dull during use, l 'provide means for grinding the cutting edge thereof as desired, or as thecutter rotates. For such purpose l have shown a rotary grinder or emery wheel 44 secured upon shaft 45, that is journaled in bearings on a standard or upright 46 carried by table 28. Said upright is adjustably mounted upon said table, whereby the emery Vcutting edge of said cutter is preferably bev- 4eledfl have shown plate 48 set at an angle to table 28, whereby the emery wheel is v correspondingly located at an angle with respect to the cutter, and as the cutter becomes reduced in diameter the emery wheel may be adjusted as required with relation to the cutting edge. lfn order to permit the emery wheel to be adjusted angularly with respect to the cutter, l have shown the foot 47 as mounted upon screws 5l entering threaded lugs 52 on table 28 at opposite ends of said foot, whereby the latter may be set at different angles with respect to table 28, to correspondingly tilt the emery wheel. Screws 53, located in threaded apertures in foot 47 on opposite sides of a line passing through screws 51 and adapted respectively to bear upon plate 48, serve to retain said plate in set position, whereby the emery wheel may be set and retained at a desired angle with respect to the cutter, so that the face of the emery wheel at one side of its axis only will engage the cutting edge of the cutter. retain said screws in set position. By the means described the emery wheel and cutter may be moved together along the frame with respect to roll 6 as table 28 is moved along the main frame.

lln order to rotate the grinder or emery wheel 44 l have shown a pulley 55 secured upon shaft 45 and receiving a belt 56 that passes over a pulley 57 driven by shaft 3, as by being secured to sprocket 25, or provided with a key entering groove 3a, of shaft 3, whereby the latter shaft rotates said pulley. Said 'belt is also shown passing over a pulley 58 journaled upon a suitable support on table 28. Since there are three pulleys angularly disposed receiving belt 56, the latter will properly rotate the grinder or emery wheel in any position of adjustment of the latter. lijn order to finish or smooth the side of the cutter 20 opposite Nuts 54 on screws 53 serve toits beveled edge or face, as acted upon by the grinder or emery Wheel 44, I provide a 'smoothing stone or emery block 59 shown journaled in a clamping device 60 supported upon table 28. Said clamping device is shovvn comprising a bar or the like 6l and aI clamping plate 62 secured thereto by screw 63, the opposing faces of said bar and clamping plate being shown curved in the nature of a clamp to grip the stone or emery block 59. (See Fig. 9). An upright 64 is secured upon table 28, and is provided with a flat head 65 upon which bar 61 rests, said bar being shown longitudinally slotted at 61a to receive a. screw 66 working in a threaded aperture in head 65, whereby bar 61 may be adjusted for adjustment of stone or emery 60 along the face of cutter 20. By means of screw 68 (Figs. 1' and 2), Working in threaded apertures inhead 65 and bearing against bar 61, the latter may be retained in set position annularly with respect to the face of cutter 20, to retain the stone or emery 59 at a desired angle .with the face of the cutter. The stone or emery 59 may be longitudinally adjusted in the

clamp

60, 62 With respect to the face of cutter 2O,l as may be required, ovving to Wearing avvay of the Working end of the stone or emery or the adjacent face of the cutter. By means of the arrangements described With regard to the grinder and emery it will be understood that When the cutter is moved back from roll 6 the grinding Wheel or einery l1 Will serve to sharpen the rotating cutter, and at the same time the stone or emery 59 will smooth the opposite face of the cutting edge, and when the cutter is moved to the roll the sharpening of the cutter vill be discontinued.

Since t-he rolls to be cut into spools or reels in the example illustrated comprise Webs of cloth, paper or other fabric Wound upon the tubular core 6, and since Such core is to be cut or severed through for the spools or reels. and asthe cutter is to be adjusted, step by step, along the roll a distance equal to the Width of each spool to be cut, I have shown rod 5 as grooved at 5a longitudinally on the side opposing the cutter Figs. 3 and 6) in such manner that the cutting edge of the cutter may pass through the tube or core 6a l,and partly into said groove in all positions of the cutter along rod 5, Without cutting the rod. The stop 32 may be set to engage arm 22 to limit the advance of the cutter toward rod 5 and into its groove. so that the cutter may sever the material of the rotating roll and the tube or core 6a in accordance with the diameter thereof.

ll'hen the spools or reels are to be cut from the roll of fabric, it is merely necessary to move the arm 8 outwardly, swing it to one side free from rod 5, slide the roll upon said rod, replace arm 8 in connection With rod 5, connect the roll with the head 10a, and start the machine for rotation of the roll on the stationary rod 5. The operator may then operate Wheel 38 to move table 28 and cutter 20 to bring the cutter to the desired position alongl the roll. A scale indicated at 92 (Figs. 1 and 3) carried by table 28 and suitablyl located with respect to the plane of cutter 20, enables the operator to determine the distance of the point (from the adjacent end `of the roll) at which the cutter should be located to cut off the desired Width of spool or reel from the roll. Arm 26 then may be depressed, causing the rotating cutter to be moved against the roll to sever the latter, the stop 32, as before explained, preventing the cutter advancing too far toward rod 5 but sufficiently far to cut through the tube or core 6a. The cutter then may be moved back from the roll, and Wheel 38 may be rotated to advance the cutter along the roll the desired distance for cutting off another spool or reel, such operations being repeated for as many spools or reels as are to cut from the roll.

An advantage of my improvements is that rod 5 is rigidly supported at both ends, so

that the roll that-rotates on the rod Willl have little, if any, vibration, and Will resist the thrust or pressure of the cutter, thereby enabling the spools or reels of fabric to be cut' from the roll accurately and smoothly. Another advantage is that the length of the rod uponv which the rolls are mounted may be relatively short, since the rolls are not required to be fed along the rod for each cutting operation, since the cutter is to be moved relatively to the roll. This arrangement enables reduction inthe dimensions of the machine, hence in the cost thereof, over cloth roll cutting machines in which the roll is fed along its supporting shaft relatively to the cutter. My improvements enable also the production of a more rigid, economical and expeditiously operating machine.

W'hile I have described my invention as adapted to cut rolls 'of fabric Wound upon a hollow tube or core, it will be understood that the machine may be used to cut other material rotative upon a stationary rod, and the cutter may have a smooth or toothed cutting edge as desired.
