November, in the same year. The English, Irish, and Scotch patents are in the name of Moses Poole, Esq., (of the firm of Poole and Carpmael, of the Patent Office, London ;) the French in the name of Charles Cunningham, Esq. (father-in-law of Charles Lafitte, of the firm of Lafitte, Blount & Co., bankers, Paris ;) the Belgian in the name of Henry Truffaut; the Prussian in the name of Platzhoff and Haenal, silk manufacturers, Bruggen, near Crefeld; and the American in the name of Jeremiah Wilbur, Esq.* (of the firm of Masters, Markoe & Co., merchants, New York.) The last named patent is dated March 12th, 1842, but has only 14 years to run from the date of the English one above named. Fig. 218, represents a front elevation of this improved loom. Fig. 220, a longitudinal vertical section. Fig. 221, a plan of a part of the loom. Fig. 222, a front view of the Jacquard cylinder and frame which carries it, showing the card protectors. Fig. 223, is a detached section of the lay, &c., showing a front and side view of the weft puller or tightener. Fig. 224, shuttle. Fig. 225, the slide of the stop motion detached. On the different Figs. of these drawings, the letters of reference are the same. a a, the frame of the loom; b, the lay; c, (Fig. 218) the reed. The take-up motion rollers dd, placed one above the other just under the breast-beam, are geared together by the cog wheels d', (Fig. 218;) the upper take-up roller is pressed down by a lever and weight d3, (Figs. 219, 220 and 221;) on the axis of the lower one is a pulley d2, (Fig. 219) from which a band or belt e3, passes down to a simliar pulley e2, on the cloth roller e, (Fig. 220;) this band is tightened with more or less force by the pressure of the pulley e', (Fig. 219) attached by a stud to a bent lever es, governed by a moveable weight. f, (Figs. 220 and 221) is a horizontal shaft on the outside of the frame, placed at right angles to, and on a level with the cam shaft, on the end of which is a bevel wheel ƒ', (Figs. 218 and 221) meshing into the bevel wheel f2, on the shaft ƒ, (it will be perceived that by changing the relative size of these wheels different relative velocities will be given to the shafts ;) on the for George D. Baldwin, merchant, 35 Spruce-street, New York, has the sole management of our patents in the United States of America; to whom all communications on the subject must be addressed. ward end of the shaft f, is a worm wheel f', (Fig. 221) working into a stud-wheel g, on which is a pinion g', meshing into a cogwheel g2, on the axis of the lower take-up roller d. ii, are picker sticks; j, (Fig. 219) are the shuttle-levers or treadles, by which the picker-sticks ii, are moved; k, are the cams to put the shuttlelevers in motion (one at each side of the loom ;) m, fast and loose pulleys driven by a belt in the usual way; n, warp beam; o. whiproller-this roller is suspended on the top of two levers o, having their fulcra at o2, (Figs. 219 and 220) and extending down nearly perpendicular; the ends of these levers rest against tops o', and are held there by springs o'; this allows the warp to give way at every beat of the lay, recovering its first position when the lay retires from the cloth. The warp-beam n, is surrounded at each end by the usual friction strap, to each of which is appended a lever p, having its fulcrum at p', and running under the warp-beam towards the front of the loom; on this lever is a sliding weight p2, to which is attached a connecting rod p3; these rods have eyes in their forward ends, in which the journals of a horizontal roller q, turn; p5, (see Fig. 221) are springs attached to the rods p', which draw them forward and bring the roller q, against the cloth roller e, and the weight p2, to the extreme end of the lever. The warp yarn runs from the beam n, over the roller o, through the harness and reed over the breast-beam (which in this loom is a roller, as shown in the Figs ;) the cloth then passes down inside and under the rollers d d, and round the lower one, up between, then over the upper one and down to the cloth roller e, (this roller is clearly shown in Fig. 220.) As the cloth roller increases in size by the winding on of the cloth, the roller q, is pushed back, carrying along with it the rod p2, and weight p3, thereby lessening the tension on the warpbeam, as the roll diminishes; on taking a "cut" from the cloth roller the rod p3, is lengthened by means of the coupling at p', (Fig. 220) so as to retain the weight in the same position when the cloth is taken from the roller; the cloth is regularly drawn forward as it is woven, by means of the take-up rollers, connected as above described, with the cam shaft; the cloth is wound on the cloth roller e, with any required degree of tension, as fast as it is delivered from the take-up rollers d d, by means of the band or belt e3, and tightening or friction pulley e', the revolutions of this roller being regulated by the quantity of cloth given out. On the driving shaft r, (Fig. 221) is placed an eccentric b', surrounded by a collar to which an inflexible rod b', is attached, having a governing screw b' (Fig. 218) to regulate its length; the upper end of this rod is |
