GLASS-BAR BRACKET FOR DOUBLE-DECKER LOOIVIS- Specification of Letters Patent.

Patented Dec. 12, 1905 Application filed January 28, 1905. Serial No. 243,045.

To aZZ whomit may concern.-

Be it known that I, OTTO W. SoHAUM, a citizen of the United States, residing in Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Glass-Bar Brackets for Double-Decker Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and'use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

My present invention relates to narrowware looms, and it has reference particularly to narrow-ware looms of the type known as double-decker looms, wherein two sets or tiers of goods, the one above the other, are woven at the same time. Heretofore the two sets of guiding or supporting means at the breast-beam for the two tiers of webs have been mounted in fixed relation to each other and there was no adjustment vertically provided for except as respecting the breastbeam and said guiding or supporting means together bodily. Thus if the guiding or supporting means for one tier of webs was but a trifle more or less spaced from its complement than the corresponding tiers of shuttles were spaced from each other. the resulting deflection of one web or the other caused the corresponding shuttles to be held out of true by the webs, producing an undue wear on the shuttles and their blocks.

The present invention has for its object to provide, therefore, for relative vertical adjustment between the two tiers of web guiding or supporting means referred to.

It also has for its object to provide for adjustment of the various parts of either of said guiding or supporting means laterally independently of each other, so that different widths of webs can be accommodated in the same loom.

Other objects of the invention will appear in the further description thereof.

In the accompanying drawings, Figures 1 and 2 are rear and vertical sectional views,

respectively, of a breast-beam fitted up with my improved web guiding or supporting means in one adaptation thereof. Figs. 3 and 4 are rear and vertical sectional views, respectively, of a breast-beam fitted up with my improved web guiding or supporting means in which the glass bars instead of beglass bar.

ing continuous from end to end of the breastbeam, as in Figs. 1 and 2, are in sections, one for each web. Figs. 5 and 6 are rear and vertical sectional views, respectively, of a breast-beam fitted up with my improved web guiding or supporting means in another adaptation thereof; and Figs. 7 and 8 are rear and vertical sectional views, respectively, of a breast-beam fitted up with my improved web guiding or supporting means in still another adaptation thereof.

a in the drawings is the breast-beam, and 6, Figs. 1 to 6, a metallic strip or plate secured to the back face of said breast-beam by screws 0 or otherwise in such manner that its top and bottom edges are free or clear of the breast-beam.

Referring to Figs. 1 to 4, d designates brackets which are clamped to thestripb in the manner hereinafter described and which serve to support the glass bars over which the webs extend. These brackets are constructed as follows: 6 is a casting having a recess f in the back thereof formed at the top with a downwardly-projecting flange or lug g, with which cooperates a set-screw h, set in alinement with said lug or flange to secure the bracket to the strip, as seen in Figs. 2 and 4. t'is a projection on the front face of said cast ing, and j a clip secured thereto by a set-screw is, said projection and clip having opposed substantially half-round recesses Z, in which is received the lower glass bar m and a packing 11., of wick or, the like, surrounding the In order to adjust the pressure of the clip against the glass bar, the set-screw k is disposed between the recessed portion of the clip and a toe 0, which bears directly against the projection 2' of the casting. The

casting has a block p secured against its front' upper portion by a set-screw 9, arranged in a slot r in the casting, and secured to this block by a set-screw s is a clip 6, said block and clip having opposed half-round recesses a, in which is received the upper glass bar 2;. As in the case of the clamping means above described for the lower glass bar, the setscrew 8 is disposed between th e recessed portion of the clip and a toe w thereon, which bears directly against the casting. The abutting faces of the casting and clip 25 are roughened or serrated, so as to securely hold the block in the position to which it is adjusted. In

Figs. 1 and 2 the glass bars are continuous from end to end of the breast-beam; but in Figs. 3 and 4: they are sectional, each section being held by two brackets, the sections for the upper tier of webs alternating with those, for the lower tier of webs. In this instance in order to prevent the glass-bar sections from endwise movement caps .e' are formed integrally on the clamping portions proper of the brackets, taking against the ends of said sections.

Referring to Figs. and 6, the brackets 1 are constructed as follows: 2 is a casting having a recess 3 in the back thereof formed at the top with a downwardly-projecting flange or lug 4:, with which cooperates a clip 5, held to the under side of the casting by a screw 6 to secure the bracket to the strip 6. Said clip bears against a lug 7 of the under side of the casting, forming a sort of fulcrum therefor. 8 is a projection on the front face of casting 2, and 9 a clip cooperating therewith to receive the lower glass bar 10, said projection and clip having substantially half-round recesses 11, which receive said glass bar and its surrounding packing 12. Against the front upper portion of the casting 2 are arranged clips 13 and 14, having half-round recesses to receive the upper glass bar 15 and its surrounding packing 16. The adjacent faces of clips 9 and 13 converge toward the casting, and between them is received a wedge 17, which may be drawn toward the casting by a screw 18, mounted in the casting. 19 is another screw arranged in an overhang 20 of the casting 2 and taking against the clip 14:. By means of the screws 18 and 19 the Various clips can be made in an obvious manner to exert more or less pressureon the glass bars in securing them in place.

Each of the constructions so far described, it will be observed, comprises two clamping members, each carrying a web-supporting clevice (glass bar 022, o, w, or 3 and one being secured to the other for adjustment vertically and the latter being secured to the breastbeam.

Referring to Figs. 7 and 8, wherein only a vertical adjustment is provided for, 21 is a bracket secured to the back of the breast beam by screws 22, which are mounted in the breast-beam and penetrate a vertical slot 23 in a'flattened portion 24 of the bracket. The slot-and-screw arrangement permits vertical adjustment of the bracket and some lateral adjustment, the latter depending'upon a slight looseness in the fit of the screws in the slot. The upper end of the bracket projects above the top of the breast-beam and carries a horizontal round arm 25, over which a web of the upper tier of webs extends, being flanged, as

somoe at 26, to prevent the web slipping off. The lower tier of webs extends past the bracket 21 over a bar 27 on the breast-beam. Both webs then extend down through slots 28 in the breast-beam.

It will be understood that I do not wish to be limited to the precise construction herein described and shown.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a loom adapted to weave goods in a plurality of tiers, a breast-beam and a means thereon for supporting the webs being woven in a plurality of tiers, said means comprising brackets adjustable vertically to vary the distance between the tiers of webs and also adjustable laterally relatively to each other, substantially as described.

2. In a loom adapted to weave goods in a 1 plurality of tiers, a breast-beam and a means thereon for supporting the webs being woven in a plurality of tiers, said means comprising the devices over which the webs directly extend and two clamping members each carrying one of said devices and one being secured to the other for adjustment vertically and the latter being secured to the breast-beam, substantially as described.

3. In a loom adapted to weave goods in a plurality of tiers, a breast-beam and a means thereon for supporting the webs being woven in a plurality of tiers, said means comprising the devices over which the webs directly extend and two clamping members each carrying one of said devices and one being secured to the other for adjustment vertically and the latter being secured to the breast-beam for adjustment laterally, substantially as described.

4. In a loom adapted to weave goods in a plurality of tiers, a breast-beam and a means thereon for supporting the webs being woven in a plurality of tiers, said means comprising the devices over which the webs directly extend, a casting secured to the breast-beam, a clip coacting with the casting to hold one of said devices and a clamping member for holding the other of said devices, said clamping member being adjustable vertically in the casting, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of January, 1905.

OTTO W. SCHAUM.
