To all whom. it may concern:

Be it known that I, ANTONIO MARCANTE, a subject of Italy, residing at Manville, town of Lincoln, iii the county of Providence and State of Rhode Island, have invented certain new and useful Improvements iny Reeds for Looms, of which the following is a specification, reference being had therein to the ac the shuttle tluough theopen shed wher-e it rides directly on the lowenwarpfthreads, and it is found in practice that in the weavingof silk and other fine threads, as the shuttle is thrown back and forth across the la'yit has4 a tendency to roughen up the fibers. and sometimes breaks the delicate threads as it comes in contact with them. To obviate this difiiculty I have provided a reed cony, structed as above described with outwardly extending parallel memberswhich allows the said threads to pass through the reed inthe usual way. When the shedv is open these threads pass -down between and lay beneath the upper edgessofthese extensions which then form a bridge or grating over which the shuttle may pass without coming in contact with these delicate threads. The dents that have the extending portions may be placed at any desired intervals in the reed. The

Shanks of said dents to which these exten- 4sions are attached are similar in construction to the ordinary dent and are secured to the reed in the usual manner like the rest of the dents.

It is also found in practice that when the shuttle is driven rapidly across the loom it sometimes has a tendency to rise and engagel the upper threads of the shed and often leaves its path entirely andv ilies out ofthe loom. To obviate this difficulty I have also provided extensions on. some of the dents to project outward. from the upper edge of the reed, thus formin two sets one above and one below the pat i of the flying shuttle and vbreast beam at the front of the loom.

when the shed is open the warp threads-lare drawn into the spaces between the extensions so that it is impossible for them to he touched by the shutt through the shed.

The invention 1s fully set forth in. this e in passingr on its way specification and more particularly pointed out in the appended claims.

In the accompan 'ng drawings: Figure 1 is an elevation, looiring at the end of a loom and showing some'of the parts in section. Fig. 2-is a perspective View showing a portion of a reed and representing the dents that have the outwardly extending feet arranged at intervals throughout .the length of the reed. Fig. 3-is an enlarged detail of a dent provided with the extending foot.l Fig. 4f-

is an end view showing a numberof thejex# tensions and the connecting rod passing throu h saidendsby which they. are suporteil and also showing the collars or spacers etween said ends'which prevent them from moving on the said rod. Fig. 5is a side elevation of a washer or spacer in section.

Referring to the drawings, at 1 is the usual 2 is the yarn beam and 3 the lay. On this la is mounted the reed 4 in the usual Way. 'ilhe essential feature of this invention lies in the construction and arrangement of the' reed dents. Some of these dents are i provided with an extension or Vfinger 5 projecting outwardly and at right angles to the shank 6 and near one end thereof.- The outer end of this extension is nicely rounded over and has a downwardly extending portion 7 which portion is provided with 'a hole 8. These dents with their extensions are placed at intervals throughout the length of the reed some being at the lower edge of the same and some at the upper edge of the reed to better control the direction of the shuttle. extensions may beaplaced on all of the dents in the reed' if desired, but on very fine reeds such as that used in the weaving of silk, it is not found necessary to have these dents extend oftener Athan on every fourth or fifth dent and those extending from above need not be as close together as those below as the have less work to do. vThe outer ends These of t ese extensions are all bound together by a stay rod 9 that passes through the eye 8 in each, said rod also being threaded through a collar or spacer 10 which is placed between the ends to hold themparallel and in the desired position. The extension at each end of dles 12h.12 serve forme(v by these edges the reed may be supported from the lay by dropping down into a notch in said lug as shown at 11 in Fig. 4, thus nicely supporting the whole against the action of the flying shuttle. y

The loom to which my improved reed is attached works in the ordinar way, thehedto spread t ewarp threads to open the shed and by their action the lower threads 16 are carried downward beneath the surface or upper edge 14 of the lower extensions 5-5. The upper threads of the shed are in like manner carried above the lower edges ofthe upper extensions 17 where the shuttle cannot come in contact with them even though it should rise and run along in contact ywith the lower'edges of said extensions. While the threads vlay in this )osition the shuttle 15 is thrown'across the lav riding on this bridge orn grating which carry said shuttle entirely clear of both threads of the shed.

The device is simple and practical in construction and'accomplishes the object for Awhich it is designed.

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

1. A reed for looms comprising a plurality of rigidly supported dents, a number of said dents being each provided with an integral 'arm extending at approximately rightangles therefrom and arranged to form a grating, a

supporting rod passed through the outer ends of said arms, and means for maintain-v ing uniform-spaces between the outer ends of said arms. s

r2. A reed for looms comprising a pluralit of dents, a number of said dents being eac provided with an integral arm extending at approximatelyright angles therefrom, said arms being arranged in sets, one set being lodated adjacent the top of the reed and the other set adjacent the bottom of the reed, and sup orting rods passed through the outer en s of each set of arms.

3. A reed for looms comprising a plurality l of rigidly supported dents, a number of said dents being each provided adjacent one end with an integral arm extending at right angles therefrom and arranged to form a grating, and means for preventing lateral movement of the outer ends of said arms.

4. A reed for looms comprising a plurality of dents, a number of said dents being each provided adjacent one end with an integral arm extending at right angles therefrom,

said arms being arranged in sets, one set be ANTONIO MARCANTE. Witnesses HOWARD E. BARLOW, E. I. OGDEN.
