Application March 1947, serial No. 733.368 In Great Britain March 12, 1946 Claims.` (Cl. 285-54) This invention relates to textile apparatus and particularly to leasing combs.

vInleasing combsrof the type hithertocommonly employed the dent Wires are self-supporting, being bent to form support points in various ways. The present invention is concerned with new types of combs in which the dent wires are supported in the required positions by means of suitable members attached to or forming part of the frame of the comb.

According to the present invention, a leasing comb comprises a bottom baulk or bottom frame member, a series of long and short dents secured to said bottom baulk or bottom frame member and alternating along the length thereof, the spaces for the accommodation of warp threads between each short dent and the two adjacent dents being of diiierent depths, and a top baulk or top frame member adapted to secure the tops of the long dents and detachable from the dents to allow warp threads to be dropped between the dents. A suitable form of top baulk for the purpose comprises a helical coil of wire, the successive turns of which are adapted to t between the successive long dents, and two longitudinal members or strips adapted to t inside said coil, one on each side of the series of long dents so as to lock the coil in position. The turns of the coil are slipped between the dents from one side of the comb, and one of the longitudinal members is slid endwise into the coil on the other side of the comb so as to effect the locking. The second longitudinal member may also be slid endwise into the coil, on the firstmentioned side of the comb, each time the top baulk is secured. Alternatively however, the second member, after the top baulk is once assembled, may be permanently fixed to the coil by the soldering of each turn of the coil thereto.

The bottom baulk may similarly comprise `a wire coil for spacing the dents and a pair of longitudinal members ttin'g in said coil and, since the bottom baulk is not required to be removable, the turns of the coil may in this case be soldered to both longitudinal members, and to the dents also, to increase the rigidity of the comb. Rigid end members may be provided, secured to each end of the bottom baulk and extending parallel to the dents, and the longitudinal members of the top baulk may be detachably fixed to said end members.

Preferably the working position of the top baulk is slightly below the tops of the dents, so that the threads may be dropped in between the tips of the dents while they are still rigidly heldin position. The longitudinal member or members are then withdrawn, the spring is drawn out sideways from the dents and the threads drop down between the dents, after which thespring is reinserted between the dents and the longitudinal member or members replaced and fixed to the comb frame. In order to protect the tops of the dents and to help to keep them in alignment, there may be provided a metal cap which iits closely`over the tops of the dents and is secured at each end to the end members.

By way of example one Vform of leasing comb according to the present invention will now be described in greater detail with reference to the accompanying drawings in which Figure l is a front elevation-of the comb and Figure 2 is a sectional side elevation.

The comb shown in the drawings comprises two D-shaped members 3 cut out of metal plate having a thickness equal to the width ofthe dents, as indicated by the section 4 shown in the right-hand part of Figure l. The curved portions 5 of the D-shaped members serve as handles and the straight portions 6 constitute vertical members to which the baulks and other horizontal portions of the comb are attached.

The bottom baulk of the comb comprises two narrow strips 'l iixed at each end to either side of the bottom of the straight portion 6 of the handles. The lower ends of the dents 3 fit into the spaces between the strips l. The bottom baulk also comprises two members I 0, each of which is in cross-.section a segment of a circle and which are ixed to the handles 3 at points justabove the strips l. Around the members Iii'is wound a length of steel wire H in the formof a spiral, which is fixed to the bottom baulk by soldering as indicated at I2 (Fig. 2). The dents 8, 9, which are alternately long with straight ends (dents 8), and short with slightly bent ends (dents 9) are spaced along the length ofthe comb by the coils of the spiral wirev Il and are aligned transversely by means of the baulk members 1.

Each short dent 9 is soldered to an adjacent long dent 8 on one side thereof at a point I3 approximately 1A; inch below the tip of the short dent so that the space between dents on that side of the short dent is shallower than the space between dents on the other side and constitutes a hook into which a warp thread can be located. This also serves to increase the rigidity of the assembly.

The upper baulk also comprises two members of segmental cross-section l5, I6 which are debolts I'I and nuts I8 above the short dents 9 and., about one inch below the tops of the long dents 8, which are located in the apertures formed by the coils of the spring I9` and V.the.-twobaulk members I5, I9. In inserting-the spring I9-and members I5, I6, it is convenient to apply them just above the tips of the short dents .9, where the comb is more rigid by reason .of the. soldered` points I3, and to slide the assembled-.topbaulk up to its nal position after the.members I5' and I6 have been inserted in the spring` 159.'. A4

metal cap ts snugly over the tops of the dents and isvdetachably xed to the-handlesby means of bolts2'l and wing-nuts 22. The cap protects the-topsof the dents9 and also helps .to keep them in alignment.
