CHENlLLE-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 605,118, dated June 7, 1898.

Application filedj une 22, i397.

To all whom it may concern:

Be it known that I, WILLIAM McCLEAnY,

a citizen .of the United States, residing atAmsterdam, county of Montgomery, and Stateof 5&N6W York, have invented certain. new and fisefullmprovements in Ohenille-Outtin g Machines, of which the following is a specification.

The invention relates to such vimprovements; and it consists of; the novel construction and combination of parts hereinafter describedrand subsequently claimed.

Reference m'ay be had to the accompanying drawings and theletters of reference marked thereon, which form a part of this specifica tion.

Similar letters refer to similar several figures.

Figure 1 of the drawings is a vertical section of my improved machine, taken transversely of the cloth T supportingrolls, bedplate, and cutterT- shaft. Fig, 21is atop :plan view of the bed-plate and-aportion ofthe cut-1 ter-shafit andeutting-disks'; Fig.3 is aver: tical section, taken on the broken line 3 ,3 in Fig. 2,- throughfthe' transverse feed mechanism l .Fi -Atis t rl tyr ewpf DQ iOH f the cutter-shaft and cutting-disks and grind-j partsin the ing mechanism for-sharpening the cutters.

Fig. '5 is a view in elevation of a broken-away portion ofthe side frame of the machine,showing the brake mechanism for controlling the tension-roll. 1

The objectof my invention is to provide an improved machine'for cutting the filling-j threads of chenille cloth intermediatelyof the Warp-threads in theoperation of making chenille cord. f 1

Referring to the drawings, A represents a cloth-roll adapted to support a web of chenille cloth wound thereon and permit the same to. be unwound as it is fed to the cutting mechanism, and B is a similar roll adapted to receive thechenille cords "formed by cutting.

the web.

Inte'i'med iately; of: the rolls and B is 10- cated the cutting mechanism, comprising a seriesof rotary cuttingdisks 0 and a bedplate D cooperative therewith.

E E are idle-rolls for guiding the cloth and cord, and F is a tension-roll locatedbetwee the cloth-roll and bed-plate.

The cutting-disks are fixed upon a rotary seen no; 641,844. on model.)

tter.-shaft O, which shaft, together with the several rolls, has end bearings in the frame mf any known form for the purposes drawings. Oomparatively rapid rotary movements may be imparted to the cutter-shaft and comparatively slow rotary movements to thecord -roll B in any known'manner, whereby the cloth may be drawn through the maand the cord wound upon the cord-roll.

My invention relates more particularly to the construction of the bed-plate and its supported mechanism and to the means for maintainin g the cutters in effective condition. The bed-plate comprises a metal plate provided along one edge,-Wl1iOh is adjacent to the cuttershaft, with a series of slots D, adapted-to receive the respective cuttingdisks,-whereby. the walls of saidslots cooperatewiththe rotatingldisks to cut the cloth as the, same is drawn over the bed-plate. The opposite edge of the plateisleft'plain and is surface D and the undercut plane sidcsur face. D5 of the plate. H a H i ,f/ Intermediat'ely of the cutter-slots D, I provide a seriesot grooves D alternating with the slots and adapted to receive the warpthreads of the cloth and guide 'the same between the cutters, whereby the cutters can engage and sever only the filling-threads of the cloth. These grooves extendpart way across the upper surface of the'plate and terminate in. the plane surfacej-Dfk" To insure the properoperati'on of the cutting mechanism and thelocation'of the warpthreads in the grooves of the bed-plate, it is necessary to maintain the cloth under tension during the cutting operation. V 4 As heretofore commonlypracticed the tension mechanism consisted'of a brake applied to the cloth-roll to resist the unwindingmove- 'ment of the cloth. On account of the extremely soft and yielding character of the cloth used for this purposeaconstant'retarding forceapplied directly to the roll by means of a -brake produces a variable tension upon the cloth as the same unwindsfrom the roll. It is also found difficult to maintain a uniformtension upon the cloth on account of the fact that cloth designed for thispnrposeis chine across the paths of the cutting-disksof the machine, hich frame and bearings of this invention and are omitted from the formedlby'the intersection of the upper plane usually woven in a web twice the width that can be accommodated in the cutting-machine. The web is therefore divided along its longitudinal middle line, and the two pieces so formed are separately submitted to the action of the cuttingmechanism. Each of the pieces formed by thus dividing the web is provided along one edge with a selvage which is thicker and less yielding than the body of the cloth, while the opposite edge, being freshly cut, is perhaps more yielding than the body of cloth and much more yielding than the selvage edge. For these reasons it has been found necessary to have an experienced operator in constant attendance upon each of the cutting-machines heretofore employed, who was almost continuously engaged in straightening and smoothing the web of cloth as it passed from the cloth-roll to the bed-plate.

In my improved machine I provide a tension device which acts upon the cloth directly and a short distance in advance of the cutters, whereby I am able to avoid the greater part of the variation in tension upon the opposite edges of the cloth. The tension comprises the tension-roll F, provided with a roughened surface adapted to engage the cloth, and a brake F, engageable with the pulley F fixed on the tension-roll shaft F The surface of the tension-roll can be roughened in any known manner, as by applying thereto a covering of coarse sandpaper or other substance which will prevent the cloth from slipping upon the roll.

As a means for overcoming the effect of the difference in texture between the selvage and cut edges of the cloth, which difference results in the gradual creeping of the fabric transversely of its path of movement through the machine, I provide transverse feed mechanism in the form of two rolls G G, each 1'0- tary upon a horizontal axis in bearings supported by the bed-plate and so located that the path of the cloth is approximately tangential to the circumference of the rolls. Each roll G has hearings in a yoke-bracket G", fixed on the upper end of a spindle G which passes through an aperture in a flange G on the bed-plate, the bed-plate being recessed to receive the roll and yoke-bearin g and provided with an aperture at G", through which the upper part of the roll projects. The yoke, spindle, and roll can be rotated by turning the spindle in its aperture in flange G and can be held in any desired angular position by means of the spring ,which incloses the spindle and bears at its upper end upon the under side of flange G and at its lower end upon the pinion G fixed upon the spindle, whereby the yoke is frictionally held against rotativc movement by engagement with the upper surface of flange G The rolls G are provided with projecting spurs G, which penetrate the cloth, and by adjusting the roll so that its axis is oblique to the line of movement of the cloth through the machine and to the bed-plate more or less lateral throw can be given the cloth by reason of the oblique path which the spurs are caused to traverse as the roll is rotated by the engagement of the cloth therewith. By varying the obliquity of the axis of the roll the cloth can be fed transversely in the direction of the lateral throw of such spurs, more or less as desired, and by locating one of such rolls near each edge of the cloth I am able to wholly control the movement of the cloth as it is fed to the cutters. As a convenient means for adjusting the rolls I provide a spindle II, rotary in the bed-plate outside of the path of the cloth and provided on its lower end with apinion II, engageable with the pinion G, and on its upper end with a handle I1 projecting above the bed-plate.

As a means for sharpening the cuttingdisks I provide the grinding-disk R, rotatively mounted upon a suitable support R, which support is pivoted upon a sleeve R movable longitudinally of the red It, fixed in a position adjacent to and parallel with the cutter-shaft, the sleeve being also rotary upon the rod. The grinder-support is provided with a handle R, by means of which the grinding-disk can be raised or lowered or moved laterally to bring it into proper engagement with the cutting-disks successively. The disks are rotated while the grinding-disk is held in engagement with them succcs sively.

The grinding-disk may be made of emery or other desired abrasive material and may be supported in any known manner.

In Fig. 1 of the drawings the path of the cloth through the machine is indicated by the dotted line T, and in Fig. 2 a brokenaway portion of the cloth is shown in position upon the bed-plate and indicated by the letter T.

Vhat I claim as new, and desire to secure by Letters Patent, is

In a machine for cutting chenille cloth, and in combination, a series of rotary disk cutters; a bed-plate slotted on one edge to receive the several cutters and having its opposite edge plain and formed by the intersection of the plane upper and side surfaces of the plate, the slotted edge and neighboring upper surface of the plate being provided with warp-thread grooves located intermediately of the cutter-slots and terminating in the upper plane surface of the plate; transverse feed mechanism located in the path of the cloth near the cutters; a cloth-roll; and a brake-controlled tension -roll having a roughened cloth-engaging surface located between the bed-plate and cloth-roll, substantially as described.

In testimony whereof I have hereunto set my hand this 12th day of June, 1897.

WILLIAM MOCLEARY.
