IMPRQVEMENT IN MECHANISMS FOR OPERATING QOMBER-BOARDS.:

The Schedule Vreferred tho .in these Letters Patent and making part'of the saxne I, JOHN STEWART TEMPLETomof Glasgow, in the county of Lanark, Kingdom of Great Britain and I reland, have invented certain Improvements in Carpets,

of which thefollowing is a specication.

Nature `(and Objects 'of the Invention.

My'invention relates to theworking of the comberboard or boards, in connection with the lhe usual jacquard apparatus of the carpet-loom may, with suitableinterpolated cards, be used for controlling the action of the coloredv warps ou the under side, in addition to producing the usuatguring effect,

` and may, if wished, eeen form apattern on the under side,or separate jacquard apparatus may be usedfor the under-side action;-

In either case; the coinber-board or hole-board wilt' not be used in the ordinary way to raise the whole of the colored w'arps, for the passage underneath of each ground-shoot; at the saine time amodiiied effect may be obtained by using the ordinary single comberboard, to raise the whole ofthe colored warps at intervals, so regulated that only every second or other more distant ground-shoot passes under them.l

Heddles or healds, or theirequivaleut, may be used 'instead of the jacquardapparatns for controlling the under-side action, and for tw'illing and so binding in the colored warps that are thrown to the under side suiiciently to form a regular compact surface. For example: Such -heddle action may4 be obtained by making the comber-board or' hole-board in sections, and by working such sections in rotation, like ordinary heddles.

Description of the Accontpctnying Drawing.

Figure 1 is a front elevation, partly in section, showing the arrangementlof` the weaving appaiatus.

Figure 2 is a sectional plan, to show better certain j parts not fullyl seen iu fig. 1.

Description of the Apparatus;

The harnessLthreads a (of which only a few are shown) are passed through holes in three comber or hole-boards@ 2V 3,' but these boards are made to act jacquard, as

on separate sections of the threads, by knotting lthel threadsat different heights, and so that, for example,

: a thi-rd of "the whole. may be acted on by` board 1, a.

second third by board 2, and a third third by board 3. The boardsl 2 3 are guided by vertical rods 4, xed

by means of brackets to thev side frames 5, and the "thence upward to the jacquard apparatus above, (not shown in the drawing.)

At the time for lifting each board, the corresponding cords 10 are drawn up by the jacquard, and the bolts 9 are moved out, as indicated by dotted lines at .12, so that, .on the `rods 7 rising, that board is caught and lifted.

The parts of the jacquardcards corresponding to the cords 10 are, of course, perforated to suit the orj der in which it is desircdto have the separate boards 1 2 3 successively lifted.

It is obvious thatiustead of three combeI-boards or` sections any other Aconvenient number may be used.

Claim..

The comber or hole-boards,1nadc to act on separate sections of -the threads, and guided by the vertical rods 4, iu combination witha cam for lifting the rods 7, which elevate the boards with the` clutch-pieces 8 and slide-bolt 9, and its spring, with the cord 10 passing around the guide-pulley ll, and operating in connectiorrwith` the jacquard, substantially as described,

forthe purpose specitied JJ S. TEMPLETON.
