REED FOR LOOIVIS.

Specification of Letters Patent.

Patented @ct. 6, 12914.

Application filed March 7, 1913,5e1ia1 No. 752,596. Renewed March 4, 1814. Serial No. 822,479.

To all whom it may concern Be it known that 1, PAUL A. WAGNER, a

citizen of the United States, residing at Carlstadt, in the county of Bergen and State of New Jersey, have invented a certain new and useful Improvement in Reeds for Looms, of which the following is a specification.

In the common construction of reeds the dents are held separated prior to the soldering operation by unyieldin spacing means so arranged that in assembling the parts the number of dents per inch is arbitrarily determined by such spacing means, and .if through variations in the spacing material or for any reason the spacing means employed fail to provide the desired number there is no method by which the fault may be corrected.

The object of my invention is to provide yielding spacing means by which. a reed hav ing any number of dents per inch may be produced, within certain limits, by simply compressing the series of dents to lessen the spaces between them until thedesired number is reached, and also to provide a reed of this character of simple and economical construction in which the dents shall be uniformly spaced throughout its length.

The invention consists in certain novel features and details of construction and arrangement by which the above objects are attained, to be hereinafter described.

The accompanying drawings form a part of this specification and show two forms of the invention.

Figure 1 is a front or face view of a reed containing an approved form of the invention, with a portion of the bands removed at one end. The remaining figures are on a greatly exaggerated scale with the dents abnormally separated and the solder omitted for clearness of illustration. Fig. 2 is an elevation corresponding to a portion of Fig. 1, showing the dents separated by the ribbons, and one band removed. Fig. 3 is a corresponding vertical section. Fig. i is a horizontal section of the same with the ribbons in plan view. Fig. 5 is a vertical section, partly in elevation, the plane of section being indicated by the line 5-5 in Fig. 3, and showing the dents nearer together than in Fig. 2. Fig. 6 is a face view of one of the ribbons. Fig. 7 is a section of the same, taken on the line 77 in Fig. 6. Fig. 8 is an elevation of the inner face of one of the bands. Fig. 9 is a correspondingsection, on the line 9-9 in the preceding figure.

Similar letters of reference indicate like parts in all the figures. 7

Referring to Figs. 1 to 9 inclusive, A A are the dents, B B the end-posts and C C the bands; the dents are plain strips of thin steel as usual and are received between the bands and held by solder, not shown, subsequently applied. D and-D are narrow ribbons of thin metal interlaced in pairs with the dents near the ends of the latter, and

each following a serpentine path, folded upon and partially inclosing the opposite edges of alternate dents, and so arranged that each dent has each of its edges thus inclosed, one by the inner ribbon D and the other by the outer ribbon D, the two ribbons crossing between each dent and the next as clearly shown in Figs. 2 and 4. Thus engaged the dents may be forced together in the direction of the length of the reed in a manner somewhat analogous to the action of an accordion-bellows, and as both ends of the dents are engaged each by two oppositely placed ribbons, the spaces between the dents may thus bereduced by compression without afiecting the perpendicularity of vthe dents or their angularity relatively to each other and to the face of the reed.

In order to facilitate the bending of the ribbon at the edges of the dents and permit acute angles to be formed, the side edges of the ribbon are notched oppositely as at d cl in Fig. 6, to provide properly located weakened lines on which the bending may take place. The angles of the ribbons projecting beyond the dents are received in grooves c 0 provided for purpose on the inner face of each band C. It is apparent that the spacing may thus be varied within a considerable range from the lar est permitted by the greatest angularity of the bends to the smallest, in which latter condition the dents will be closely compressed upon the ribbons between adjacent dents and be separated by a space but little in excess of the thickness of such ribbons. This adjustability or yieldingness may be attained by various means; the ribbon arrangement above de scribed is preferred for the reason, among others, that dents of the usual form may bev employed.

To increase the resiliency of the spacing body of the ribbon spring arches adaptedto be flattened by pressure on the series of dents and thus reduce the spaces.

In order to avoid distortion due to twist 111g strains on the dents, the flanges D are bent alternately 111 opposite direction so that when the ribbon is folded theflanges extend always in the same direction, as in Fig. 5, both at the upper ends of the dents, and at the lower ends, not shown in that figure.

The deiuz-s, end-posts, and bands are united by soldering in any approved manner, 'or otherwise secured, while held in the properly spaced condition.

*lteeds thus constructed are adapted to be easily and cheaply manufactured by -nia chinery, and. the yielding feature permits thedents to be located uniformly with exactlyithe desired number of spaces per inch.

1. In a recd, a series of dents, bands therefor and aspacing :ineinber interlaced sinuously with such dents and partially 'inclosing the latter in its angular bends.

2. In a reed, a series of dents, bands therefor, and a yielding compressible spacing membervinterlaced sinuously with such dents and partially inelcsing the latter in its an gular bends and constructed to vary the spaces between such dents by compression of said spacing member.

3. In aireed, aseriesof dents, bandstherefor, and a spacing ribbon interlaced with such i dents and part1 ally inclosing :the latter in its angularbends.

4. In a reed, aseries of dents, bands there for, and a. spacing ribbon interlaced with such dents and partially :inclosing adjacent dents inits angular bends, said ribbon having suitably spaced weakened =portions adapted to facilitate such bending.

In a reed, a seriesof dents, bands therefor, and a spacing ribbon interlaced with such dents and partially inclosing adjacent dents in its angular bends, said ribbon havingsuitably spaced notches in its edges to facilitate such bending.

6. In a reed, a series of dents, bands therefor, a pair of spacing ribbons interlaced with such dents and each partially inclosing each of said dents in its-angularbends, the bend of one ribbon receiving one edge of each dent and the bend of the other ribbon receiving theopposite edge of the same dent, said ribbons crossing each other be tween dents.

7. .lna reed, a seriesofdents, bands therefor, a pair of spacing ribbons interlaced with such dents and each partially inclosing each of said dents in its angular bends, the bend of one ribbon receiving one edge of each dent and the bend-of the other ribbon receiving the oppositeedge of the same dent, said ribbons crossing each other between dents, said bands having grooves on the inner faces to receive said bends.

8. In a reed, aseries of dents, bands there for, a spacing ribbon interlaced with such dents and partially inclosing the dents in its angular bends, and flanges on the margins of said ribbon, bent out of the plane of the latter and arranged to apply on the face of an adj acentdent.

29. In areed, a-series of dents, bands thercfor, a spacing ribbon interlaced with such dents and partially inclosing the dents in its angular bends, said ribbon having notches in its edges to facilitate such bending, and flanges on the margins of said :ribbon between S110l1 110t0l16$,b611b outo-f the plane of the ribbon and arranged to apply on the face of the adjacent dent.

In testimony that I claim :the invention above set forth I afi'ix my signature, in presence of two witnesses.
