HENRY E. HURTZ, OF HAWIHO-RIT- ,NEW' JERSEY.

T 0 (IN whom it may concern:

Be it known that I, HEN Y HURTZ, a

citizen of the United States, residing at Hawthorne, in the county of Passalc and State of New Jersey, have invented certain new and useful Improvements in Textile Reeds, of which the following is a specifica- .tion.

This invention relates to improvements in reeds for use in the manufacture of textile.

a cylindrical segment of even cross section throughout, and has an arcuate wearing race.

A further object of the invention is the provision of a textile reed in which the dents. are of such special construction, and arrangement, as to allow a minimum of wear thereupon; thus effecting a practical, economical, and durable structure.

Other advantages of the improved textile reed will be apparent during the course of the following detailed description.

In the accompanying drawings forming a part of this specification, and in which like reference characters designate like parts throughout the same,

Figure 1 is a fragmentary side elevation of a front warp reed.

Figure 2 is a crosssection taken on the line 2-2 of Figure 1, and showing the relation of textile threads to the dents oi the reed.

Figure 3 is a fragmentary side elevationot acrossing reed.

length, each one of which spools has a thread I ofconsiderable width, and in order to' bring the threads to thej'proper width upon the warp, reeds must be'us ed.

f Colored goods, or those of special design require an accurate arrangement of threads upon the warp, and, inorder to insure this, and to facilitate su'ch adjustmentpa crossing reed D, relatively smaller-in width than the widthjof the creelA is used; which reed also facilitates in the bringing together of the threads for disposal upon the warp. However, before their disposition upon the w a1 ?p,.tl 1ethreads C' are required toloe arranged spaced relation to form a warp of properwidth. To effectsuch arrangement,

a front warp reed Eis used; the sanielheing relatlvely narrower in w dth than the width of the crossingreed D.

The reeds,' as used in the rna11 u facture of s lk goods today, employ dents which are subst nti ly ang in Cross-Section Due to the tensioning of the silk threads 'upon the dents ofthe reeds D and E, it has heen found that the employment ofrectangu- V ,lar dents requiresthe constant careand attention of one experiencedin the spinning of text le warps. This fact has been brought yahoutprimarily:because nicks are Worn in the edges otthe rectangular dents, due to the tensioning or the thread thereupon. The thread is thus prevented "from riding longitudinally' upon the dents and uponi doing so, (the thread ridingth'ereiipon is invariably broken This necessitatesan entire stopping offthe warp mi1l, to repair the particular thread, and may some time cause the entire .replacement of anew reed. .The dent as used upon the improved type of reed illustrated vin the drawings accompanying this specificationhas been designed primarily to do away withrthe wearing r-of ni'cks in the dent tace, thusinsuring the durability and effectiveness of the improved reed as illus- .tfated i h d awing The improved dent 15 comprises a cylindrical segment, of even cross section throughout. Each of the segments 15 has an arcuate or convex face 16, which extends through out the length of the dent; and a rear surface of back 17, which is a flat or plane surface. It is to be distinctly understood that the dent 15 is solid throughout its length, and this fact, together with the fact that the wearing or arcuate surface 16 is curved insures a permanency of such a dent over the rectangular shaped dent now in common use. The front warp reed E is provided with a plurality of the dents 15, each one being a solid spherical segment, and is secured near each longitudinal edge to the binding wires 20 as in the ordinary reed construction, by means of springs and spacing wires 21. The spacing wires 21 are uniform in thickness, and the space 22, between any two adjacent dents 15, is equal to the width of this spacing wire 21, as is clearly shown in Figure 1 of the drawings. The spacing wires are spiral in shape and extend from one side of the dent 15 to the other, for the purpose of securely binding the same to the binding wires. By this arrangement, the spaces 22 throughout the length of the reed are uniform in width, thus insuring that the dents 15 will be equally spaced upon the reed E. The binding wires 20 are rigidly secured about, and welded to the side pieces 23 and 24 of the reed structure E. End pieces 25 are then soldered or welded to the side pieces 23 and 2st and have embedded in them, the ends of the dents 15 which extend beyond the binding wires 20. Thus a staple, secure and well balanced reed structure is secured, employing the improved dent 15.

The arrangement of the dents 15 within the frame structure of the reed E is of prime importance, due to the manner in which the threads C are' received from the crossing reed D, incidental to their formation as a warp. As illustrated in Figure 5, the side 10 of the reed E faces the crossing reed D. From observation of the threads 0, as shown in Figures 2 and 5 of the drawings, it can readily be seen that the threads C nearest to the side pieces 23 and 24 of the reed struc ture E, enter at an acute angle to the longitudinal run of the reed E; and which angle increases for each succeeding thread C as the center of the reed E is approached, until the center thread 27, intersects the longitudinal run of the frame E at substantially a right angle. This necessitates considerable wear upon the part 28 of the convex face 16 adjacent the side 10 of the reed E, which faces the crossing reed D. It can, of course,

be seen that the wear will be greatest upon the dents 15 adjacent the side pieces 23 and 24, since the change of angle in the threads 0, and consequently the tensioning due thereto is greatest upon those threads. However the surface 28, which in reality is part of the convex surface 16, presents a rounded surfare for the thread G to glide over and there will consequently be no possibility of nicks, or grooves being worn in the surface of the dent, and which ordinarily causes breaking of the threads C.

The life of the reed E is of course determined by the wear upon the faces 16 of those dents adjacent the side pieces 23 and 24;, since the dents nearest the center of the reed E receive practically no wearing from the threads G. The front warp reed E is ordinarily centrally disposed with respect to the crossing reed D, and this fact, taken into consideration with the necessity of a front warp reed E for properly securing the width of a warp, renders it necessary that one-half of the dents 15 upon one side of the reed E, be placed with their convex faces 16 facing the center of the reed E, while the other half of the reed E has the dents 15 similarly positioned. Thus the convex faces 16 of the dents 15 upon one side of the frame face the convex faces 16 of the dents 15 upon the other side of the reed E.

hen the faces 28 of the convex surface 16 of the dents 15 have been worn down to render the side 10 of the reed E of no further alue, the reed is reversed, and the side 11 of the reed E is disposed toward the crossing reed D, thus reversing the position of the dents 15, and the suriaces 29 of the convex faces 16 will now directly receive the tensioning of the threads C, since they have e heretofore received no wear whatsoever, as can be readily seen from an observation of Figure 2 of the drawings.

The crossing reed D, as illustrated in Figures 3 and 1: of the drawings is altogether similar to that of the frontwarp reed, and comprises a plurality of dents 15 arranged in spaced. relation, by a spacing spring 35, engaging either side of the dents 15 tying them rigidly to the binding wires 36. The side pieces 3'? and -18 of the crossing reed D, similarly support the binding wires 36, and a top piece 39, is welded or otherwise secured to the side pieces 37, 38, and to the ends of the dents 15, to form a rigid crossing "rame D. The arrangement of the dents 1. within the frame of the crossing reed D is altogether similar to that described for the front warp reed E, and comprises one half of the dents 15 having their convex or arcuate faces 16 facing the center of the reed D, while the other half are similarly disposed; thus one half of the frame D have one half of the convex faces 16 facing the convex faces 16 of the other half.

The crossing reed D is provided for arranging the threads to suit the particular color or design of the broad sill: or ribbon, or other textile {goods to be woven, and is provided niimarily for the purpose of putthe flat surface 17 thereof. Thus the-spaces 11 of the reed D are subdivided throughoi'it their height, since there are generally a I number of. the inserts A0 within the space 11.

The inserts 40 are arranged within the alternatespaces 11 in parallel alignment with the top 39 of the crossing reed D, and in fact divide the crossing reed D into a plurality of subdivisions to effect the crossing in the warp; The side 43 which ordinarily faces the creel A primarily receives the threads C which wear upon the surfaces 14 of the convex faces 16. The crossing reed Dis reversible, similar to the reed E, and the side 45 can be positioned to face the creel A, in which event the surfaces 46 of the dents 15 will primarily receive the tension, and friction of the threads 0.

A broad silk reed F is illustrated in Figure 6 of the drawing and is formed altogether similar to the framework of the reeds D and E. However, the reed F is not used in the spinning of a warp, but is used on a loom in the actual weaving of a textile goods. Its purpose is to provide an accurate spacing of the threads C as they come from the warp, and is used upon a loom intermediate the warp, and the actual goods which are being woven. The tendency of goods, such as silk, which are in the weaving process, is to shrink the threads C, which is in reality caused by operation of the shuttle. As illustrated in Figures 6 of the drawings, the threads C which are being unwound, from the warp and entering the broad silk reed F, through the side 50 thereof, are arranged in parallel relation, since they come directly from the warp. However, as before stated, the shuttle tends to shrink the goods. somewhat, and produces an inclination of the threads C upon the side 51 of the broad silk reed F, as is clearly shown in Figure 6 of the drawings. Thus a warp 38 inches in width will sometimes shrink to 37 inches or 37:; inches in width. The broad silk reed F is therefore obviously necessary.

Since the tendency of the threads C is to converge after leaving the broad silk reed F, it. follows that the operation is the exact reverse of that required for the swinging of the threads C upon the warp. The dents 15 in the reed are exactly similar to the dents employed in the front warp reed and the crossing reed. The only difference lies in the arrangement of the dents within the reed structure. Inthis case, the convex faces 16 of one half of the reed F are provided to face the side piece 53 of one side of the frame F, while the other half of the dents 15 have their convex faces facing the other side piece 54: of the otherlside of the broadsilk reed F. Thus the arrangement is exactly reverse to the dents in the reeds D and E. Sincethe threads G approach the reed F in parallel relation, it follows that the-centeror highest portion of the arcuate .faces 16 receives the tension of the thread and theo'reatest wear will be upon this portion. I Fowever, due to the fact that the threads are inclined to the center of the frame F afterthey leave the frame,there willv be no surface for the threads C. to rub against, consequently no nicks will be formed in the dents 15. It is otherwise when the rectangular shaped dents are used, for then nicks are formed in the upper edges thereof.

From the foregoing description, it can readily be seen that a dent has been provided for use upon reeds, adapted for use in connection with textile manufacture, and particularly in the silk industry.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of the invention or the scope of the subjoined claims.
