M km, muvr- Patented June 17, 1952 REED SUPPGRT Thomas Hindle, Blackburn; England Application September 28, 1949, Serial No. 118,253 In Great Britain October 7, 1948 2 Claims. 1

This invention relates to looms for Weaving and more particularly to improvements in wide and heavy looms of the type in which the slay is carried on three or more swords, these comprising the two end-swords and one or more intermediate swords, and in which the bottom bar of the reed is secured in any suitable manner to the slay while the top bar is supported by a reed-cap.

The object of the invention is to provide improved means for supporting the reed-cap at intermediate points in its length, such supports being additional to the support obtained in the usual manner by bolting the extreme ends of the reed-cap to the end-swords, also to provide convenient means of adjustment at each such intermediate supporting point so that the reedcap and the reed may be set and firmly held in correct alignment throughout their length and in such manner as will efiectively resist the load imposed on the reed when beating-up the weft.

According to the present invention a vertical lever is pivoted on each intermediate sword behind the slay, the upper arm of the lever projecting upwards through the warp yarn and having the reed-cap, which it supports, bolted to its upper end, the lower end of the lever extending into a vertical recess in the sword and being engaged by screws for adjusting the alignment of the reed-cap and reed and for locking the parts after adjustment.

The invention is illustrated in and will be described with reference to the accompanying drawings:

Fig. l is a rear elevation showing the upper parts of two intermediate slay-swords and the improved means for supporting the reed-cap,

Fig. 1a is a detail modification of the vertical lever, I

Fig. 2 is a vertical cross section through the slay and reed-cap correspondin to Fig. 1,

Figs. 3a, 3b and 30 show respectively three typical sections suitable for the vertical lever where it extends upwards through the warp yarn.

Referring to the drawings, the slay l is firmly bolted to each intermediate sword 2 which, in common with the two end-swords (not shown) and any further intermediate swords necessitated by the weaving width of the loom, is adapted to swing about a pivot at its lower end (not shown) and is rocked by a crank and connecting rod or the like in the usual manner.

The warp yarn, indicated at Y, is controlled by healds H, and the woven cloth W is drawn forward over the front rest F.

The bottom bar 3b of the reed 3 is clamped 2 to the slay I by the reed-clamp 4 and bolts 4a. The top bar 3a fits into a tapered groove 6av formed in the reed-cap 6. Fig. 2 shows the reed 3 in contact with the fell 5 of the cloth W in which position the reed is required to resist the load imposed on it by beating-up the weft.

According to the present invention each intermediate sword 2 is provided with means for supporting the reed-cap 6 so as to resist deflection when the reed beats up the weft. As shown in the drawings, the reed-cap 6 is bolted to the top end of each vertical lever I which is pivoted approximately mid-way in its length on a pin 8 carried in lugs 9 formed integrally with or bolted to the respective intermediate sword 2 behind the slay. The upper arm 11) of each lever 7 projects upwards through the warp yarn Y and the top end of each lever is provided with a slotted part It! as shown by Fig. 1a, or with slotted ears H, as shown by Figs. 1 and 2, by which it is rigidly secured to the reed-cap 6 by bolts Illa.

The lower arm (a of each lever 1 extends downwards below its 'pivot pin v8 into a recess or pocket I2 formed in the respective intermediate sword, and adjusting screws Na and I2b are provided to rock the respective lever forward or backward and to lock it firmly in position when the reed 3 and reed-cap 6 are correctly aligned.

The upper arm of each lever 1 where it projects upwards through the warp yarn Y is preferably made of relatively thin elliptical cross section or an approximation thereto, as indicated in Figs. 3a, 3b and 30 respectively.

Once the vertical levers 1 have been correctly adjusted and locked in position there is no necessity to disturb them when changing the reed, for which purpose the bolts Illa are slackened and the reed-cap 6 raised to clear the reed, thereby permitting its removal and another to be fitted in position.

The details of construction may be modified to suit slays and reed-caps of different form or construction from those indicated in the accompanying drawings.

I claim:

1. In a wide weaving loom of the type having a slay carried on end swords which support the slay for swinging movement for beating up the weft, a reed secured to the slay and supported by a reed-cap, and intermediate swords for supporting the reed-cap at intermediate points in its length, the combination with each intermediate sword, of a vertical lever pivoted on such sword on a horizontal axis behind the slay, said lever having an upper arm projecting upwardly from the sword and through the warp yarn and having the reed-cap secured to its upper end, and having a lower arm extending downwardly below the top of the sword, and means on the sword and cooperative with the lower arm of the lever for adjusting the reed-cap and reed in the direction of swing of the slay to align their intermediate portions with their end portions and for locking the lever after such adjustment.

2. In a loom as defined in claim 1, wherein each intermediate sword is provided with .a -.vertical recess in its upper end in which the lower arm of said lever is mounted for pivotarmcvement about said horizontal axis, and said adjusting and locking means comprises a pair of opposed screws mounted adjustably in the sword to project into said recess and abut against opposite sides of the lower arm of said lever.
