To all whom it may concern:

Be it known that I, FREDERICK W. Moon,

a citizen of the United States, residing in the city, county, and State of New York, have invented a new and Improved Machine for Ornamenting Plush and Similar Matea rials, of which the following is a specification.

My invention'relates to a machine used for ornamenting the surface of plush and similar materials by cutting away portions of the surface to produce the ornamentation thereon, and an object of my invention, among others, is to provide a machine of this kind in the use of which the ends of the fibers comprising the pile or nap may be neatly, rapidly and effectively cut away to produce an ornamented surface having designs of wide and varying character.

A machine, in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a portionof a machine embodying my invention.

Figs. 2 and 3 are detail views, scale enlarged, showing a section of my improved gage roll and a knife and their action upon the fibers in the operation of the machine.

Fig. 4 is a detail view showing a-slig'htly diiferentform of gage roll.-

Fig. 5 is a perspective View of a portion of a machine showing a little different form of feed roll.

belt knife skiving machine of well known construction as to many of its parts, my invention contemplating such a construction of a roll in place of the gage roll that the fibers comprising the nap or pile of plush or similar material will be so distributed and supported as to permit an effective action of the cutting knife, this roll thus constituting .a fiber distributing and supporting ledger in carrying out my invention I employuponthe fabric operated upon, the depth and conformation of the depressions in the supporting roll being accurately calculated as the measure of the depth and conformation by which the cuts to be made in the ma-- terial is determined.

A roll embodying my inventioncomprises part of the machine partially shown in the drawings herein in which the numeral 5 denotes the feed roll of a belt knife skiving machine, that rests against a bed roll 6 of rubber or similar material, although this bed roll may be in's'ome instances composed of a comparatively hard material. The numeral 7 indicates spreading .rolls supported in front of the feed roll in position todeliver a sheet of material into the throat between the feed roll andthe fiber adjusting and supporting ledger roll 10. After passing.

through between said rolls the fabric may be led around a tension roll 11 from whence it may be delivered on to a reel 12. A. knife 13 is supported with-its edge between the fiber supporting and feed rolls, as shown in Fig. l of the drawings and in position to operate upon the material as it is deliveredagainst it from between said rolls. The mechanism comprising the rolls hereinbefore mentioned except as to the fiber supporting roll, may be of any ordinary form and. may be driven in any suitable manner, and being of old and well known construction a further and detailed description is omitted herein.

My invention has to do especially with the construction of the fiber distributing and supporting ledger roll- 10 that is provided with depressions 14 of a depth having special reference to the length of the fibers comprising the pile or nap of the plush or other material to be operated upon or ornamented by use of the machine. In the ornamenting operation of the apparatus the fibers 15 that are engaged by the raised or outer'feed surface 16 of the roll 10 will be underneath the knife as shown in Fig. 3 of the drawings. The fibers 17, on the contrary, which are fed or moved opposite the depressions 14, will stand uncompressed and as the surface of the rolls approach each other they will rise freely and without restraintin a curvilinear position into the depressions, and the, latter will be of such take hold and cut off the ends of the fibers projecting into the depressed surfaces. @By reason of the frictional hold and support of the bottom and side of the depressions against the ends of the fibers so that the knife will operate upon them I have termed such holding surface a friction super-surface. It is of the utmost importance that the depth of the depressions 14 be accurately determined to free the fibers from compression and the friction super-surface be, therefore, accurately positioned, as if such friction super-surface be too far from the feed surface of the roll except on narrow and small-spaces the fibers will either be sup-. ported not at all, or to such a slight extent as to enable them to give way and bend in front of the cutting knife, whereas, on the contrary, if these friction super-surfaces be .too near the feed surfaces of the roll then the fibers will be bent over to such an extent that the knife will either not take hold, as the fibers will be bent downward toward the body of the fabric andpassed underneath the knife in a manner similar to that above described with respect to the fibers. 15 which are located against the raised or feed portions of the outer surface of the roll, orelse the hold of the knife will be-so uncertain that the fibers will be cut unevenly, some passing underneath the knife without being cut andothers being cut of uneven lengths.

' ihay employ a saddle which is commonly supporting the fiber supporting roll inter-- used in machines of this class, or I prefer to use a fiber supporting roll rest roll 22 rotatably mounted in the lower edge of machine frame plates 23 and pressing against and mediate its ends.

In the form of apparatus illustrated in Fig. 1, a sectional feed roll 5, composed of rings on a loose shaft resting on a bed roll 6 and regulated by ring plates 9 and of a size and so arranged that they cooperate with the feeding surface on the roll 10, is made use of, the object being to arrange rings to engage the feeding surface only of the roll 10 and to act only in connection with such surface and'thus permit an unrestricted action of that portion of the roll comprising the friction super-surface. This arrangement ismore particularly adapted to the production of straight line effects in the or namented surface.

In the form of apparatus shown in Fig. 5 the feed roll comprises a solid roll 24 which is in fact a supporting roll for the fabric, it being understood-that the feed roll in my improved machine'does not exert any undue pressure upon the fabric nor more than is required to support the fabric and insure its movement against the surfaces of the fiber supporting roll with a pressure suflicient to, I

fbed the material !uniformly against the friction super-surface and to the knife and to obtain this result the upper and lower feed rolls 5 and 10 shown in Fig. 1 should turn at the same speed. If in the operation of the machine upon material of a comparatively lightweight it shall be found that the friction drive usual in the ring roll feeding device as shown in Fig. 1 is not sufficient to control. and turn each individual ring at the required speed, then the lower feed roll may be a solid roll constructed to be the equivalent of the ring roll drivenby positive drive .to turn at the same speed as the fiber supporting roll and as shown in Fig. -5 of th drawings. I have found that the best results are obtained with as little'pressure as possible between the feed roll and the distributing and ledger supporting roll, this pressure in fact being just sufiicient to move the-fabric along and this movement will be obtained with'the rolls at such distance apart that the uncut fibers will be depressed to the same extent substantially as the length to be cut from the other fibers.

It is equally important that the fibers to be cut-shall rise freely and without restraint into therecesses provided for their reception, as if they are compressed or forced I into the depressions and are caused to assume an abnormal position, the cutting will be very irregular and unsightly. When thus positioned in the depressions they must be supported as a ledger blade supports a shear to permit the knife to readily cut off the ends and this support may be effected in at least two ways. When the depressions into which the fibers rise are of such a width that the ends of the fibers will all be located within each depression at the time that the knife first contacts with thefibers in 30 sition against the knife and are t 45 said 50 retain said fibers in a su 55 roll to feed said fabric,

' ascetic direction of movement of the surfaces of the roll toward the knife. When, however, the

depressions are of such width that the knife will come into contact with the front edge of the mass in a depression before the ends of the fibers are all located in that depression then other means of support are provided, in such case the bottoms of the depressions being accurately located so that the ends of the fibers will rise against the 115 bottoms and be thus supported and without distortion. 7

It will thus be seen that. the back'walls of the depressions act after the manner of a ledger blade in a cutting machine, the

ledger blade element, however, being movable instead of stationary, this ledger blade .action consisting in a carrying of the fibers,

by the rear walls of the depressions toward and against the knife, that does the cutting and I have, therefore, used this term ledger roll in the specification herein to describe the supportin roll having such action, and in i .which rol the fibers, in their natural and unrestrained state are led in an upright poall supported during the'action' of the knife.

While I have shown and described herein a. satisfactoryconstruction of mechanism for accomplishing my'purpose, this may be de- 3'5 parted from to a greater or lesser degree and yet be within the spirit and intent of the invention.
