The present invention relates to new and improved reed constructions for weaving on circular looms. '1 F A primary object of the invention is the embodiment of novel and improved reed constructions of the aforesaid type, wherein an efficient structure is realized with a minimum of parts.
Briefly stated, the characteristic features of the reeds of the present invention which, as indicated, are especially adapted for use on a circular loom, are their annular shape and the fact that the reed strips or dents are secured at one end only, while the other end projects freely. A reed of this kind may thus consist essentially of an annular metallic body provided with notches or slots in which the dents, which may for example be stamped from sheet metal, are inserted. The particular shape of the dents may vary in accordance with the purpose for which the reed is to be used and in accordance with the manner in which the dents are secured on their support, since as will hereinafter appear this may be accomplished in various ways.
Presently-preferred embodiments of the invention, wherein the aforesaid objectas well as other objects and advantages are realized, are hereinafter described in detail, with particular reference to the accompanying sheets of drawing, wherein:
Fig. 1 is a top plan view of a portion of an annular reed body according to a first form of the invention;
Fig. 2 is a cross-sectional view through the reed body, taken along line II-II of Fig. 1;
Fig. 3 is a perspective view of a reed dent corresponding to this type of reed body;
Fig. 4 is a sectional view corresponding to Fig. 2 but showing the parts in assembled relationship;
Fig. 5 is a top plan view of a'portion of an annularreed body according to a second embodiment of the invention;
Fig. 6 is across-sectionalview through the reed body, taken along line VI-VIof Fig. 5;
Fig. 7 is a perspective view of a reed dent corresponding to this second embodiment of the invention;
Fig. 8 is a sectional view taken along line VIII- Fig. 11 is a perspective view of a reed dent corresponding to the third form of the invention; and
Fig. 12 is a sectional view taken along line XII-XII of Fig. 9 and showing the parts in assembled relationship.
Referring first to the form of the invention illustratedin Figs. 1 to 4, the reed body is shown at Hi. It will be understood that this body is as sociated with the loom in the conventional way and that, while only a portion is shownfor the sake of economy of space, the entire reed body defines a complete annulus, the construction of the non-illustrated portion being the same as that of the illustrated portion. (This applies V also to the reed bodies of the second and third shown by the dotted line l3 in Fig. 2. The preferred shape of dent l2 for this embodiment of. the invention is shown in Fig. 3.
Annular recesses l4 and I5 are provided on the inner and outer lateral surfaces of reed body II], as shown in Fig. 2. At its upper end, each slot H opens into recess l4, while at its lower end it opens into recess I5.
The dent l2 comprises an inclined median portion i6 which, when the parts are assembled, is positioned in its slot II, the upper inclined edge I! being essentially flush with the upper inclined surface of reed body l0. Each dent l2 also com prises a free upwardlyprojecting end, which may be configured as shown in Fig. 3 or may be suitably bent or thickened or arched at certain points. Each dent l2 further comprises two spaced downwardly extending legs t8, I9 which,
in the assembled device, are seated respectively on the floors of recesses M and I5; see Fig. ,4. Rectangular recesses 25 and 2! are provided re,- spectively in the outer edges of legs l8 and 19, their location being such that, as shown in Fig. 4, they can overlap respectively with recesses 34 and I5 to provide grooves for the reception of wire securing members 22 and 23, shown in cross section in Fig. 4. The free ends (not shown) of these wire members maybe clamped and soldered or otherwise fastened together, thereby insuring firm positioning of the dents.
Figs. 5, 6, 7 and 8 of the drawings disclose a second relationship of parts according to the invention. The reed body 30, being as before adapted for use on a circular weaving loom. is annular. In this embodiment, however, the crosssectional configuration of the body 33 is specifically different from that of the previously-described reed body It); see, more particularly, Fig. 6. Moreover, the specific configuration of the corresponding dents 3| (Fig. '7) differs from that dents l2- of the first embodiment of the invention.
The reed body 30 may be aptly described as of modified inverted-T configuration. The crosspiece of the T is rabbeted at one corner to provide a recess 32, the purpose of which is hereinafter described. The stem 33'. of the inverted T projects upwardly and is beveled off, as at 34. The upstanding projection 33 is, of course, annular (see Fig. and narrow grooves 35 of slight depth are out on the inside and outside lateral surfaces thereof, the said grooves being radially alined in pairs and extending exactly or approximately in the-direction of the axisof the reed as can be seen from Fig. 5.
,The dents 3| maybe aptly described as of modified inverted-Y configuration, the-downwardlyextending arms of the inverted-Y being adapted, when the parts are in assembled relation, to straddlethe rib- 33 while being inserted in the corresponding grooves 35, the free ends of the arms extending respectively into recesses formed in the upper surface of the cross-piece of the reed body 30;, see Fig.3. For securing the dents 3i, there are provided a plurality offlat stay bolts 35, each provided with an eye adjacent each end, as may beseen from Fig. 8.
The assembly of the parts may be conveniently effected. byfirst arranging the dents 3 i which for this purpose are provided with correspondingly located openings 3'! (Fig. '7) in rows on an annular sheet metal strip 38 (shown in section in Fig. 8,. and whose free ends may be tied together in any desired conventionalmanner such as solder ing or the like)a stay bolt 36 being inserted aftereach certain number of dents as determined by ,the position of the boreholes 39 in the reed body (see Fig. 5). The thus-assembled parts are then mounted on the annulus 33, the projecting parts of the stay bolts being passed through the corresponding boreholes and the dents being fitted into the corresponding grooves 35. Final- 1y,1.shims or wedges 48 are severally inserted through the eye in lower end of each stay bolt, which end projects into cut-out recess 32, hereinb'efore described. The stay bolts may be pro vided,:if desired, with threaded cylindrical lower endsso that the fastening may be achieved with the aid of nuts screwed thereon.
Still, another type. of construction of the reed ring and dents isillustrated in Figs. 9, 10, 11 and 12. Here, the ring assumes theform of a hollow annulus 4| which is essentially U-shaped in cross sectional configuration (Fig. and the grooves 42,.in which the corresponding dents. 43 are inserted, are cut on the two inside walls of the ring. The ring 4|. with the radial grooves, 42 extending in the exact or approximate direction of its axis is, shown, in plan view in Fig. 9. The corresponding dents 43 areshownin Fig. 11.
Thedents are, in this embodiment of the invention, secured on the reed body with the aid of a flatmetallic. holding ring 44, the free ends of whichmay be tied together in any desired way, as by means of solder or the like. This ring 44 runs through the horizontalv portions of the key slots .45, one,of..wh-ich is provided inthe lower end of each dent 43. A second ring 46, shown in section in Fig. 12, passes through the openings 41 correspondingly provided in the dents (Fig. 11).
In assembling these parts, the dents 43 are first arranged in rows on these two rings 44, 46 and are then inserted in the grooves 42. Then, screws 48 (Fig. 12) are inserted from below through corresponding boreholes 49 (Fig. 10) in the bottom of the reedbody 4 l, and are screwed into threaded openings provided in the holding ring 44. Fig. 12 shows the assembled parts.
The scope of this invention extends to still other variants besides the three illustrative examples herein described.
It is possible',.for example, for the free projecting end of -the reeddent as shown in Fig. 7 to be given. a shapeas shown in Fig. 3, and it may also be provided with a hole through which a wire ring can .be drawn, just as the dent shown in Fig. 11 comprises the hole 41: through which the wire ring 46 is drawn.
An example of another combination that can be made is one in which use is made of the stay bolts shown in'Fig. 8 instead of the fiat ring 44 for securing the reed dents shown in Figs. 11 and 12. In this case, the dent shown in Fig. 11 has no-recess formed-in it, but a hole is punched in the middle of the dent like theone indicated at 31 in Fig. 7, so thatthe securing can be effected by means of the ring- 38 (Fig. 8) asdescribed for the example of the second type.
In the reeds illustrated-in the drawings, the dents are positioned vertically and radially on their support, but the dents may be so positioned that the angle-formed by them with thereed ring is less than degrees, or thatthey are not exactly radial but positioned in an approximately radial direction.
The reed dents employed in the above given examplesare flat and level. It is however of advantage toslightly curve the ends of the dents that engage in the slots made in the reed body.
A particular type of construction of areed consistsin using dentswhose free projecting ends are suitably bent,.orelse'thickened or arched at certain points.
