To all 'whom t may concern UNITED STATES PATENT oEEICE.

HENRY KELLY, OF THE BOROUGH or MANATUNK, PHILADELPHIA COUNTY, PENN- sTLvANIA.

JACQUAED. f l' i Specification of Letters Patent 1\To..5j,9.:`i?,y dated November 28, 1848.

Be it known that I, HENRY KELLY, of the borough of Manayunk, in the county of Philadelphia and State of Pennsylvania, have invented new and use Improvements in J acquard-Machines, so as to .weave figured or plain cloths or other woven fabrics thereby withoutfaJ square axis (usually termed cylinder cr pat-tern cards and so as to raise and sink or depress alternately the sheds of the warp equally, and thus to adapt the said machine better for power-looms than it heretofore has been; and I do hereby declare that the following is a full and exact description of the said improvements, reference being made to the annexed drawings and index thereof, as part of this specification.

In lieu of the square or four faced cylinder, `with its four-cogged wheel and pattern ycards thereon, (as heretofore used in the said machine) I place a round cylinder (B Figures l and 2)'-into the periphery or surface whereof I bore, in straight lines lengthwise of the cylinder, any requisite number of small holes into which I fasten pins (by screws cut into them or otherwise and common screw nails for fastening into wood will answer as these pins), so that in weaving, each pin in the row lwill push one of the needles of the machine in a direction from the cylinder. These needles I arrange so that their ends form one straight row or file parallel with the cylinder; and in each? needle are two holes or eyes through each of which passes one of the upright hooks. To the lower ends of the twohooks passing through the same needle a shaft or heald is attached by its ends, and the needle, being pushed by one of said pins, causes the shaft to be moved evenly up or down by this pair of-hooks, and so on with every needle that may be required to form the desired figure in the web. The pins are intended, the same as the holes in the pattern cards,to form the figure sought to be woven; and may be carried in the cylinder so as-to produce the same effect as the pattern cards heretofore cut through the cards; but not liable to be displaced, by rapid motion, as cards are. On the end of the cylinder I fix a cogged wheel (c c Figs. l and 2) in the teeth or cogs of which the catch (cl Fig. l) works; and when the sliding or lifting frame (A Fig. 1 sometimes called the griff frame) lis moved upward, the cylinder is moved around by Val@ Said @ach assistance ef one moth or cog; the number of teeth or cogs in the wheel, 1s equal to the number of rows of pins vin the cylinder, and is equal in effect to the same number of treadles in a common loom; l

because every tooth of the wheel that is thus moved causes so many shafts or healds, as

the figure may require, to be acted on in order to draw the lower shed of the warpdown as far as the upper shed is raised; and thereby preserve the tension of the warp as equal as possible. I place a pair of racks (g g Figs. 4 and 5) in each end of the slid- Ing frameV or griff, with their teeth toward each other; one of each pair of those racks is fastened to and moves up and down with the sliding frame the other of eachpair of racks slides up and down in a groove; and between each pair of these racks I place a pinion (la Fig. 5), turning on a fixed central pivot, and its teeth or cogs working into those of both racks simultaneously. This pinions center being immovable,- it is turned partly around by the fixed rack as it rises and falls with the sliding frame or griff; and the pinion, by this movement, causes the opposite rack to move in its groove the same distance with the fixed rack, but in the opposite direction. The hooks that the woven figure requires to be raised are lifted by the lifting bars of the sliding frame or griff; and the rest of the hooks, being suspended on rods as (J Fig. 3) passing through the open slit in the lower end of each lifting hook, are at the same time depressed a distance equal to that which the former hooks are lifted. The ends of these rods are fasmuch cheaper than if made by the machinery heretofore used, whether operated bymanual labor or other motive power.

What I claim as my invention, and desire to secure by Letters Patent, is not the said cylinder or polygon, cogged wheel, racks, pinion, or any or all of them; but

WhatI so claim and wish so to secure is- The combination, application` and use of the said round cylinder with pins or screws in its surface and; cogged wheel Onets end,V

machine, as described in the fication; A

In testimony whereof I hereunto set my foregoing speci- 10 `hand and aX my seal, this twenty-eighth day of September A. D. 1848.
