CHARLES J. DELMARMOL, OF FRANKFORD, ZPENNSYLVANIA.
FILE-CUTTER FOR LOOMS.
T 0 all whom it may concern:
Be it known that I, CHARLES J. DELMAR- MOL, a citizen of the United States, residing at F rankford, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Pile-Cutters for Looms, of which the following is a specification.
This invention relates to pile-cutters for looms producing pile fabrics and it has for its main object to provide a pile-loop forming and rotary cutter attachment which is adapted for association with any standard type of loom.
A further object of this invention is to furnish a rotary pile= cutter the cutting members whereof are mounted in spaced relation and are operated to always out the pile loops directly central so that an even pile is insured for the length of the weave.
A still further object of this invention is to provide a guard in conjunction with each individual cutting member which is so fashioned to effectively prevent the accidental cutting of the weave while at the same time it divides or spreads the cut pile so that ease in production is greatly increased.
With the foregoing and other objects in,
view, my invention consists essentially of a rotary mandrel having a series of spaced disk cutters mounted thereon in combination with a corresponding series of guard members serving to separate the cut pile, said guard members having associated therewith the pile loop forming wires.
In the further disclosure of the invention reference is to be had to the annexed sheet of explanatory drawings constituting a part of this specification, and in which like char acters of reference designate the same or similar parts in all the views.
Figure 1 is a sectional end elevation of my improved pile cutter, loop former, and the associated parts of a pile fabric producing loom, only such parts being illustrated as will enable those skilled in the art to which the invention appertains to get a clear understanding thereof.
Fig. 2 is a fragmentary plan of the same.
Fig. 3- is an enlarged broken detail of the rotary cutter proper and mandrel; and
Fig. 4- is a perspective View of one of Specification of Letters Patent. Patented Feb, 15, 1921. Application filed December 13, 1919. Serial No. 344,654. I
the guard elements hereinafter more specifically described.
Referring to the drawings, the numeral 10, des1gnates the loom harness and behind WhlCh there is securely mounted across the loom-not showna bar or roller 11 over which lengths of wire are folded and the.
ends connected to constitute bands or wires 12, said wires 12 being weighted by weights 13 suspended therefrom. by pulleys 14. These wires 12,'are passed through the usual eyes 15 in the harness 10 and are conducted over the breast beam 16 and threaded through eyes 17, in the ends of guard elements 18 hereinafter fully described. Supported in spaced relation to the harness 10 are pedestals 19, provided with upper and lower bearings 20, 21, respectively and freely rotatable in the latter there is mounted a shaft or roller 22, over which the cut pile fabric feeds down to the cloth drum 23'. Supported in the upper bearings 20, is a mandrel 24, of a length to extend completely across the width of the fabric to be produced and threaded on said mandrel 2 1, are disk cutters 25, spaced apart by washers 26,
a collar 27 and lock nuts 28 being provided:
for securely clamping the cutters in proper spaced relation.
Clamped to the outer flanges of the aforesaid pedestals 19, by set screws or bolts 29, is a transversely disposed bar 30, rectangular in cross-section and which is grooved at its lower edge 31, and provided with vertical serrations 32 on its front and rear faces, said serrations or grooves 32 being spaced apart to conform to the spacingof the pile loops and cutters 25. This bar 30, serves to support the guards 18, above referred to, and each of said guards consists of a thin metal stamping provided with a cut out part 33, adapted to fit snugly on the bar 30 and to seat in one of the rear vertical serrations 32, a heel 34 engaging in the groove 31. A thin sheet metal key 35 is passed through parallel cuts 36, and engages in the opposed adjoining vertical serration or groove thereby securely locking each guard 18 to the bar 30. It is to be here noted that each guard 18, is formed at one side with an upstanding lip or flange 37, so that when placed in position the alining cutter 25 lies between the cut away or downwardly curved main wall 38 of the guard and the flange 37, slightl to the rear of the tongue portion 39, in w ich is the eye 17 through which passes the endless wire 12. The lay is desi nated by the numeral 40, and 41 indicates-t e reed, while 42, 43, are fast and loose pulleys on the mandrel 24 for a belt drive-not shown.
I From the foregoing it will be readily seen that as the pile loops 44 are formed on the wiresl2 and the weft beaten up by the reed 41 the produced material 45 is fed over the breast beam 16 to the tongues 39 which enter the pile loops, and as said material 45 travels forward the rotary cutters 25, cut the pile loops 44 centrally while the flange 37 and cut away wall 38 of the guards 18, serve as spreaders for the pile. Furthermore it will be clearly seen that the lower edge of the cutter 25 is effectively prevented from cutting the weave inasmuch as said weave is traveled forwardly below the part 46 of the guards. a I
Still further it will be readily understood that the number of cutters 25 will conform to the number of pile loops 44 in the weft of the fabric and that each individual cutter is provided with an alined guard 18, while those skilled in the art to which my invention appertains will readily understand that when the cutters become dulled or need changing or renewal fordifierent types and width of fabric, such renewal or changing can be readily effected by removing the man drel and substituting a fresh one, or changing the cutters by first removing the lock nuts 28. Further it will be conceded that I provide a cutting mechanism cooperating withspacing guards and pile-loop forming Wires which is extremely eflicien't in use and which at the same time prevents any damage to, or cutting of, the actual weave.
While I have described one practical em bodiment of my'invention, it' will be evident that changes and modifications thereof can be made without departing from its spirit and scope as set forth by the appended claims, and I wish it clearly understood that I do limit myself to lthe precise details shown and described.
Having described my invention what I claim'as new and desire to secure by Lett atent, i V i I 1. A pile, loop-forming" and cutting attachment for pile fabric looms comprising spaced bearings, a rotary'ma'ndrel mounted in said bearings,-circularcuttin disks and spacing washers threaded on sai mandrel, means for clamping said disks and-Washers firmly in place, a rectangular cross section bar supportedbetween said bearings and provided with alined;serrations.on opposed faces thereof, a guard element associated with each cutting disk and formed with a substantially U-shaped portion and laterally prqectmg eyed tongue and a cut out port on adapted to seat on the aforesaid bar in one of the serrations, means for locking each said guard element to the bar, longitudinally extending wires threaded through the eyed tongues and the loom harness whereby the pile loops are formed, and means for keeping said wirestaut.
2. A pile loop-forming and cutting attachment for pile 'fa'bric looms comprising spaced bearlngs, a rotary mandrel mounted in said bearings, circular cuttin disks and spacing washers threaded on sald mandreh.
means for clamping said disks and washers firmly in place, a fabric feeding roller supported below and in juxtaposition to said mandrel, a rectangular cross section bar supported by said bearings and provided with a ined serrations on opposed: faces thereof, 1 a guard element associated with each cutting disk and formed with a substantially g U-shaped portion and laterally projecting eyed tongue and a cut out portion adapted to "seat on the aforesaid bar in one of the serrations, a key for passage through parallel slotsjn the .ard element and engagement in n opposed serration of the bar whereby said guard is locked in alinement with its assoc-"ated cutting disk, longitudinally extendin' wires threaded through the eyed tongues a d the loom harness whereby the pile loops are formed, and means for keeping said Wires taut.
In testimony whereof I aflix my signature.
CHARLES J. DEIZMARMOL.
