O33 WORCESTER, MASSACHUSETTS, A COB COMBEB. BOARD FOR JACQUARD MECHANISM.

Application filed. April 19,

lhis invention relates to improvements'in jacquard mechanisms for looms and it is the general object of the invention to improve upon the construction of the comber boards used in such devices.

lVhen comber boards are made for the weaving of relatively coarse fabrics such as carpets and heavy blankets, the cord holes are large so that the comparatively large drill used to bore the holes does not run out of true to any objectionable extent, and it is possible for this reason to use relatively thick comber boards. lVhere the index is liner however it is found that the smaller drills are likely to run. out of true sutiiciently to cause an imperfect board and it is the usual practice to make the finer index comber boards of thinner stock which necessitates a holding frame of stronger construction. As heretofore constructed these holding; frames have usually been made so that the edges thereof project above the comber board proper forming a depression which is found to collect dust to an objectionable degree. It is found that the dust, lint, etc. interferes with the proper action of the cords in the holes of the comber board and this condition is aggravated in the case of fine index comber boards.

It is accordingl an important object of my invention to construct the comber board and supporting structure therefor.- in such a way that the upper surface of the comber board and supporting structure are substantially flat and formed without dust-collecting pockets or depressions.

lVhere the fabric being woven is relatively wide with relation to the acquard the angle of the cords extending down from the comber board to the selvages is so great that the holes in the comber board at the end portion thereof wear more quickly than the holes at the central portions and in order to correct this defect I have made the comber board in a plurality of relatively short sections, the end portions being removable when worn without loss of the intermediate sections. In carrying out this feature of my invention I provide a holding cleat or other device which is received by notches formed in the comber board sections and the supporting structure, this construction not only permitting the removal of the lndlvldual see- 1926.

tions but also maintaining the top part of the board flat to prevent the accumulation of dust, as previously stated.

lVith these and other objects in view which will appear as the description proceeds, my invention resides in the combination and ar rangement of parts hereinafter described and set forth in the claims.

In the accompanying; drawings wherein l have shown a convenient embodiment of my invention, a

Fig. 1 is a perspective view of a portion of a jacquard comber board constructed according to my invention, the front end of the jacquard being removed to illustrate more clearly the construction thereof Fig. 2 is atop plan view of the comber ioard and supporting,structure, and Fin: 3 is vertical section on line 3-3 of Fig. 2.

Referring more particularly to the drawings it will be seen that l have provided a jacquard frame 10 having supporting lugs 11 formed on the opposite sides thereof for the purpose of supporting the comber board C. The showing of the frame 10 is of no special form as my invention can be used on a variety of types of jacquards. Said comber board C is formed of a supporting" structure 12 having end bars 13 and side bars 1-1 which may be secured together in any approved manner. Said end and side bars are of sufficiently heavy material to support the strain placed upon the comber board and the end bars 13 rest on the lugs 11 and may be held rigidly thereto by screws or other devices 16.

The inner edges of the bars 13 and M are notched as at 17 to receive a plurality of comber board sections 18 each proportioned to have the sides thereof enter the notch 17 of the side bars 14 and the end sections entering also the notches of the end bars 13. Said sections are supported by means of the ledge 19 on the bars which project inwardly from the notch.

Said sections 18 are notched as at 20 and the upper portion ofthe

bars

13 and 14 are similarly notched as at 21, said

notches

20 and 21 receiving; preferably metallic cleats or plates 22 secured in place by screws 23 which extend therethrough into the supporting frame, as shown in Fig. 3. The

inner edges of the plates or cleats 22 extend over the ledge 19 and form therewith a groove to receive the edges of the sections 18.

As shown in Figs. 1 and 2 the cleats 22 which extend along the side bars 142 may be made in several parts, one part for each lower portions of the cords receiving their corresponding warp threads (not shown).

At each pick of the loom there will be relative motion between the cords and the comber board which results in more or less wear on the holes 24- and due to thebeating up action of the loom there will be more or less lint in the air above the loom, some of which will be deposited on the top of the comber board C. Because of the fact that the top part of said board is substantially flat due to the fact that the cleats 22 are received by notches or recesses in the sections 18 and the

bars

13 and 14 this dust can be readily removed in any manner, as by compressed air. As previously stated, this is of particular advantage in connection with fine index jacquards. It will also be notedthat when the end sections become worn the cleats 22 adjacent there-to can be removed and, said sections taken out and replaced by new sections without disturbing the intermediate sections.

From the foregoing it will be seen that I have provided a comber board for jacquards constructed of several parts all so arranged that their upper surfaces are substantially flat to avoid the formation of dust-collecting pockets or recesses. It will also be noted that this feature is maintained while providing for the removal of the end sections.

Having thus described-my invention, it will be apparent that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention, and I do not wish to be limited to the details herein disclosed, but what I claim is:

1. In a comber board for loom acquards, a supporting frame comprising end and side bars of relatively heavy construction, a plurality of sections provided with cord receiving perforations supported by the frame, and retaining cleats lying partly in the frame'and partly in the sections, and having the upper portion thereof substantially in the same plane with the top surfaces of the frame and sections to afford a flat surface for the top of the comber board.

2. In a comber board for loom jacquards,

a supporting frame having side and end members, a board having side and end edges supported on the frame and said board provided with a plurality. of cord receiving openings, and a cleat secured to the frame and overlying edges of the board adjacent to the frame, the top portions of the cleat and board lying substantially in the same plane to afford a flatsurface to facilitate the removal of dust.

In a comber board for loom jacquards, a hollow frame having side and end members, a plurality of boards supported by the frame and each having edges engaging the frame and each board having a plurality of cord receiving openings therein, and a plurality of cleats secured to the frame and overlying the edges of the sections adjacent the frame, each cleat being in contact with but one section to permit ready removal of. any section without disturbing any other section.

i. In a comber board for loom jacquards, a hollow frame having side and end members, a plurality of boards supported by the frame and each having edges engaging the frame and each board having a plurality of cord receiving openings therein, and a plurality of cleats secured to the frame and overlying the edges of the sections adjacent the frame, each cleat being in contact with but one board to permit ready removal of any board without disturbing any other board, the top surfaces of the cleats lying in substantially the same plane with the top surfaces of the boards to facilitate the removal of dust.

5. In a comber board for loom jacquards, a supporting frame comprising end and side bars, a plurality of boards provided with cord receiving openings extending vertically therethrough supported by the bars, each board having edges in engagement with the frame, and a plurality of cleats secured to the side and end bars and overhanging adjacent edges of the sections, there being a separate cleat secured tov each side bar for each board.
