 LOOM TEMPLE II BACKGROUND OF INVENTION Temple rolls are conventionally made by driving sharp pins into the surface of a hard wood cylinder with the pins in adjacent rows staggered. In my pending application Ser. No. 323,524 filed Jan. 15, I973, there is shown and described a temple roll which is made by milling slots longitudinally on a metal cylinder and sliding strips having teeth along one edge into the slots with the strips in adjacent grooves displaced to provide for staggering of the teeth. Although the teeth in the aforesaid rolls are staggered from row to row there are nevertheless in a given turn about the axis of the roll a number of teeth which lie in the same plane. The effect of this is to form a separation of the warp yarns which does not completely close and so appears as a streak in the finished cloth. The purposes of this invention are to provide an improved way of making a temple roll and to provide a temple roll which will not produce a separation of the warp yarns such as to produce streaks in the finished cloth.  
 SUMMARY OF INVENTION As herein illustrated the temple roll comprises an elongate cylinder, teeth disposed on the cylinder in helical turns about the longitudinal axis of the cylinder and spacing means disposed on the cylinder between and separating the turns so that no tooth in any turn about the cylinder lies in the same plane with any other tooth in the turn. In one form the teeth are formed peripherally of circular discs containing center holes for receiving the cylinder on which they are mounted, each disc being split and its end displaced so that each disc makes a helical turn about the cylinder. Spacer discs correspondingly split and displaced at their ends are mounted on the cylinder between the toothed discs to hold them uniformly spaced along the axis of the cylinder and there are means at the ends of the cylinder for clamping the toothed discs and spacers in engagement. In another form a continuous strip having teeth uniformly spaced along one edge is formed into a helix and mounted on the cylinder with a continuous resilent or elastic spacer between the turns of the toothed strip. In still another form a helical groove is milled in the surface of the cylinder and the toothed strip is mounted in the groove. In whatever form the teeth are mounted on the cylinder they are bent laterally all in the same direction so that they lie at an angle to the axis of the cylinder. In the preferred form wherein toothed discs are employed each disc has peripherally thereof 13 teeth, two of which are at the respective ends of the disc and the remainder of which are uniformly spaced therebetween.  
  The invention will nowin be described in greater detail with reference to the accompanying drawings, wherein;  
  FIG. 1 is a plan view of a temple roll according to this invention broken away in part and partly in phantom showing the arrangement of the toothed discs and spacing discs;  
  FIG. 2 is a view taken at one end of the temple roll at right angles to FIG. 1 showning a single toothed disc and a single spacer disc before they are moved into engagement with the head at the left end of the spindle;  
 FIG. 3 is a plan view of a toothed disc;  
  FIG. 4 is an edge view of the toothed disc showing its ends laterally displaced;  
 FIG. 5 is a plan view of a spacer disc;  
  FIG. 6 is a plan view at one end of an alternate form of a temple roll in which the teeth are formed along one edge of a continuous helical strip and the latter is mounted on the cylinder with a helical spacer between turns;  
  FIG. 7 is a fragmentary elevation of a continuous helical toothed strip;  
  FIG. 8 is a fragmentary elevation of two continuous helical spacers one of which is a coiled spring and the other a coil of resilent or elastic material; and  
  FIG. 9 is a fragmentary elevation of another form of the temple roll in which a continuous helical toothed strip is mounted in a helical groove milled in the surface of the cylinder.  
  Referring to FIGS. 1-5 which illustrate the preferred form of the invention the temple roll comprises toothed members I0 mounted on a cylinder spindle 12 with spacer members 14 between them. Each toothed member comprises a disc 16 peripherally of which there are teeth 18. The disc 16 is circular, is split so as to have ends 20-20 and contains a center hole 22 of a size to fit onto the spindle 12. The teeth of which there are thirteen (13) are arranged peripherally with two of the teeth at the ends and the remaining teeth distributed at uniformly spaced intervals therebetween. The disc 16 is bent between its ends to form a helical turn about the spindle the ends 20-20 being laterally displaced relative to each other as shown in FIGS. 2 and 4. It is to be understood that it is within the scope of the invention to employ a toothed member having other than thirteen (13) teeth as long as there are an odd number of teeth and they are arranged with the teeth at the two ends one half the distance between the spacing of teeth intermediate the ends which are uniformly spaced.  
  The spacer members 14 FIGS. 2 and 5 are circular, split so as to have ends 2424, contain center holes 26 of the size to fit onto the spindle 12 and bent to form a helical turn about the spindle. The spacer members are comprised of resilent or elastic metal or material so that they will resist displacement and hence apply pressure when compressed between the toothed members.  
  The spindle 12 has at one end a head 30 of larger diameter than the part on which the toothed members and spacer members are to be assembled so as to hold the toothed members and spacers at that end and a retaining collar 32 of the same diameter mounted on the opposite end and secured thereto by a set groove 34. The head 30 and collar 32 are of the same diameter and of smaller diameter than the toothed members so the teeth project radially therefrom. The spacer members correspond in diameter to the head and collar. The inner sides of the head and collar are provided with helically formed grooves 36,38 corresponding to the helical form of the toothed members and spacers.  
  The toothed members and spacer members are arranged on the spindle alternately as shown in FIGS. 1 and 2 with a toothed member abutting the head followed by a spacer member until the entire number of toothed members and spacer members are in place whereupon the collar is mounted upon the spindle pressed axially against the last of the toothed members and secured by means of the set screw. As shown in FIG. 1 the displacement of the ends of the toothed members and the spacers is such that one end 20 of the first toothed member bears against the shoulder 40 at the inner end of the groove 36 on the head and the other end against one end of the spacer next to it. From there on the ends of the toothed members abutt. the opposite ends of the spacer members, the latter overlapping throughout length of the assembly.  
  The teeth 18 of the toothed members are bent at their roots laterally as shown on FIGS. 2 and 4 so they all lean in the same direction toward one end of the roll at an angle to the axis thereof.  
  Alternatively. as shown in FIGS. 6, 7 and 9, the teeth may be formed along one edge ofa helical coil 42 comprised of a flat strip of metal wound in a helical coil about a mandril so as to have a longitudinally extending central hole corresponding to the diameter of the spindle and slipped onto the spindle as shown in FIG. 6. In order to hold the turns of the helical coil separated a flexible coiled spring 44a, FIG. 8 is wound onto the spindle between the turns of the helical coil. A compressible or elastic element may be employed in place of the spring 44a, for example a braided or spun cord or felted packing element 44b. The toothed helical coil 42 and coil spring 44a or element 44b are clamped onto the spindle against the head 30 by the collar 32. In this form the teeth are bent laterally so that they are inclined to the axis of the spindle as in the form shown in FIGS. 1-5 inclusive.  
  A third form of temple roll is shown in FIG. 9 where the spindle 12 contains a helical groove 46 and the toothed helical coil 42 is mounted in the groove.  
  The factor common to each of the forms ofthe invention illustrated is that for any complete turn in the helical arrangement of the teeth no tooth lies in the same plane axially of the roll and, hence, in use each tooth will penetrate the cloth at a different place widthwise thereof. The purpose of this arrangement is to avoid forming permanent splits or spaces between the warp yarns and hence to eliminate defects in the form of streaks in the finished cloth.  
  The spindle may be comprised of any suitable material, for example, metal, hard wood or plastic. The toothed members and spacers are preferrably comprised of metal or plastic.  
  It should be understood that the present disclosure is for the purpose of illustration only and that this inven tion includes all modifications and equivalents which fall within the scope of the appended claims.
