REED CONSTRUCTION, ron nooiv s.

Specification of Letters Patent.

' Patented July 13, 1915.

Application filed September 23, 1913. Serial No. 791,344.

To all whom it may concern:

Be it known that 1, JOHN C. CooMBs, citi zen of the United States, residing at Midland Park, in the. county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Reed Constructions for Looms, of which the following is a specification.

-This invention relates to an improvement in reed constructions for looms.

The primary object of the invention is to provide a reed in which the dents are so arranged as to reduce friction, whereby free movement of the warp threads through the reed will be permitted, and in which knots or enlargements in the thread will pass between the dents. p

A further object of the invention is to provide a structure in which the dents may be readily positioned within the reed frame and properly spaced from each other without accurate adjustment.

A further object of the invention is tov provide a structure in which one set of dents are arranged in advance of the other, the dents of one set being disposed in staggered relation with respect to the dents of the otherv set, and in which the dents on each side present a smooth'and unobstructed surface.

For a full understanding of the invention reference isto be had to the following description and accompanying drawing, in which Figure 1 is a perspective view of'a portion of the reed. Fig. 2 a section on the line 2-2 of Fig. 1. Fig. 3 a view showing a modified form of frame. Fig. 4 a section on the line 44 of Fig. 3. Fig. 5 a detail view of a portion of the spacing frame shown in Fig. 3.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

Broadly the present invention contemplates the provision of a reed structure in which the dents are disposed in staggered relation, that is, two rows of dents are supported by the frame and are so arranged that a dent of one row will be disposed immediately between and in the rear of the dents of the other row, the reed when viewed in end elevation presenting spaced parallel dents;

It is well-known in the art that where the' dents are arranged in perfect alinement, the frictional contact of the thread with the same impedes the progress of the warp and occasions breakage when knots or enlargements occur in the thread.

The present invention is designed to provide a structure in which the threads will be held as close to one another as where the dents are arranged in alinement, and yet which will at the same'time allow them to readily p'ass between'the dents. This cannot be accomplished by merely spacing the dents, as to do this would prevent the use of such reeds in beating up fine fabrics.

In the drawings, 10 designates the frame which consists of the longitudinally disposed bars 11 and 12 arranged in pairs, one of the pairs of bars constituting the base of the frame and the other pair of bars forming the top of the frame. The ends of the frame are formed. by vertically extending spaced bars 13 and 14 which have their terminals disposed between the longitudinal bars 11 and 12., The dents are arranged in two rows 15 and 16 which extend longitudinally of the reed frame, one row being arranged in advance of the other.

In the form shown in Figs. 1 and 2, the

front row of dents is spaced from the rear the edges of the dents contacting with the bars. A strip of soft metal 19 is arranged on each side of each of the bars 17 and 18 and is disposed parallel therewith, the strips contacting with the faces 20 of the vertical bars 13 and 14:. The dents are spaced longitudinally of the reed frame at its upper and lower edges by coiled springs 21 which embrace the soft metal strips 19 and the spacing bars 17 and 18, the convolutions of said springs being disposed between the dents. I

It will beunderstood that the wire from which the springs are formed is of the same the spring, and in this manner the reeds of the front and rear section'will be spaced the same distance apart throughout the entire length of the reed frame. As is usual in constructions of this character in which a coil spring is' used as a spacing means, the springs after being positioned betweenthe dents have their convolutions permanently spaced by pouring solder between the same, whereby thepermanent spacing of the dents is attained. a

It will be' noted, particular reference being had to Fig. 4 of the drawing, that the dents arespaced the same distance 1ongitu,..

dinally of the frame as though they were side by side, and thus the fabric will be beaten up as effectually as with theusual form of reed. It will be seen, however, that the thread has free passage between the dents and that bunches or lmots in the thread may pass freely between the same without danger of breakage and without binding. Thus the construction not only permits rapid movement of the warp, but it also prevents breakage, often times occasioned by irregularities in the thread or" yarn. The many advantages of a construction of this character will beclearly apparent, as it will benoted that the same may be easily and economically manufactured, as the dents may be more conveniently assembled than when placed in alinement with each other. It will also-be seen that in use the structure is as effectual in the beating up of the fabric as is the usual form of reed, the present structure, however, operating without friction or danger of breakage when bunches or 'knots occur in.the thread or yarn.

In the form shown in Fig. 3, the frame consists of the upper and lower bars 22 and 23, the ends of which are recessed as at 24. A spacing frame 25 is supported by the bars 22 and 23. This frame consists of vertically extending side members 26 which constitute the end bars of the reed frame and the longitudinally extending bars 27 and 28, the bars 26 extending beyond the bars 27 and 28, their terminals 29 being inserted within the recesses 24 formed in the bars 22 and 23 and soldered to said bars.

1 While solder has been illustrated as the securing means, it will be noted that fastening devices may be passed through the corners of the frame, whereby the spacing I the terminals'ofthe dentsi In this frame will be rigidly secured to the longitudinally disposed bars 22 and 23. The longitudinal bars are formed of soft metal and their inner faces 30 are recessed to receive rm the dents are arranged in spaced rows, the

, dents of one row being disposed in staggered Y longitudinal bars 2 metal which are dis osed parallel with the and 28 of the frame 25 are supported on said reduced portions. In this form the coiled springs embrace the strips 32 and'the bars 27 and 28 and thereby maintain'the dents in spaced relation.

'It will also bevnoted that the structure "maybe as readily positioned on the loom' as the usual reed and that its use will not necessitate any change whatsoever in the arrangement of the race or the lay-beam, the reed frame construction being practi-' cally the same as in those reeds which are now in use, so far as its action with respect to the shuttle isconcerned.

What I claim is:

1. A reed construction for looms comprising a rectangular frame including up-.-

per and lower spaced bars, upper and lower intermediate spacing bars, front and rear dents having a staggered arrangement and disposed with their end portions inserted between the spaced and the intermediate spacing bars, and means for connecting the spaced and intermediate bars and confining the dents between them.

- 2. A reed constr'uction comprising front and rear dents having a staggered arrangement, spacing bars arranged between end portions of the dents, other bars exterior to the dents and opposite the spacing bars and at the sides thereof, and wire coils connecting the exterior and spacing bars andconfining the dents therebetween and serving as spacing-means for the dents.

. 3. A reed construction for looms compris ing a frame including longitudinal bars, the ends of said bars being recessed, a spacing frame formed with longitudinal bars and vertical bars, the verticalbars extending beyond -'the longitudinal-"bars and being re ceived within the recesses formed in the first mentioned longitudinal bars, dents disposed in spaced rows and having their terminals extending within recesses formed in the longitudinal bars, and coiled springs embracing the longitudinal bars of the spacing frame, the vconvolutions ofsaid coiled springs spacing the dents longitudinally of the frame.

4. A reed construction for looms compris ing a frame including longitudinal barsformed at their ends with recesses, a spacing frame including vertically extending portions, the terminals of which are inserted within the recesses formed in the longitu- .dinal' bars, the spacing frame being pro vided with longitudinal portions, dents a'r- In testimony whereof I aflix my signature ranged in rows on each side of the spacing in presence of two Witnesses.
