teil 5mm JOHN B. BRACKETT AAND s di" @time www WYMAN DEARBORN, or Bos'roN,A MAS- sAcHUsE'rTs.
Letters Patent No. 87,535., dated .ll/[meh 9, 1869; antedatedMwrch 2, 1869.
naPRovEMENT IN .'oTTo1\r-c'rriv.
The chedul referred-'to in these Lettera Patent and making part of the lame.
.To all 'whom it may concern salne, reference being had to the .accompanying drawings, forming a part of this specification.
This improvement is upon our gin, patented'March 26, 1867, and is designed to aiorda double-belt gin, as well as to show some improvements' which can be applied to any belt-gin, such as a newV adjustment and construction of clearers, new forms of pressure-bars, a finer and more delicate adjustment of thetension of the belt, and a new and improved rack.
In the drawingsi Figure 1 is an isometric perspective view of the gin, set up; l
Figure 2 is a plan, showing the construction of the rack; and
Figures 3 and 4 are sections of pressure-bars.
Like letters indicate like parts in all the figures.
A A arethe belts, running on rolls, as described in the patent referred to, and tightenedl bylevers 1, having fnlcra f, adjustable by set-screws s, so that the exact degree of tension required maybe given to the belt by the variation ofthe fulerum.
The cotton is fed to the gin over tables B, which are edged by rack 1'. This, is constructed, as shown in iig. 2, of a single wire, zu, looped back and iorwnrd,
' and fixed iu back, b, which is of cast-iron poured round the wires while they are set in a mould.A
The cotton fed into the gin is caught between the belt and pressure-bar,.as in the belt-gin already referred to, patented by us, and the seeds are knocked out by the clearers.
The pressure-bar .may be of one oi' four constructions: convex, as described inv tle previous patent; coucave, and arranged near one of the rollers, to lit the convexity ofthe belt, in section like an isosceles tri angle, as-shown iniig. 3; to be arranged like the convex bar relative to the belt, o`r like the concavebar -nearer the rolls; or as we consider the best form, shown in fig. 4, where C is the bar, having a hollow cut in it on the sidetoward the belt, in which is placed roller fl, vpressing against the belt, and forced up to it by spring g, either of rubber or metal, making the bear--Y ings of journal e.
The clearers are of new construction. They hang by arms h fromboxes i, which reciprocate in slots k of rock-shaft L.
The arms hA are connected by har m, upon which is fastened, by screws o, knife-blade n.
The screws pass through slots in the knife-blade,
.so that it is readily adjustable up and down. j.
Rook-shaft L receives its motion from a cranked shaft passing through boxes sliding in the slots of arms x, or in any othersuitable way to give'the rock ing or belt-crank motion.
The advantages of the double-belt gin are that all its parts andinotions, on opposite sides ofthe median ver.- ticah are' exactly balanced. The movable fulcra give a very delicate adjustment to the tension of the belt, and may be used on any gin. The roller pressure-bar, with its spring-journals, allows cotton to be fed more rapidly, with less-eareto spread it evenly over the feed-table, as in other gins, and secures its passage tln-ough the machine'.- The construction of' the rack is nruchcheaper than in the old way, with separate teeth, and quite as durable. The reciprocating boxes, at' the ends of the rock-shaft, are a novel adaptation to secure qnietness in running, freedom from shocks.
and jars, and the mode of constructing the clear-ers is an assurance that they can always be adjusted to their work much more readily than in the old way, when they vere made all in one piece. K I
We, therefore, claim as our invention, and desire to secure by'Letters Patent ofthe United States- Al. The arrzuigeinent of knife-blade '11, by screws 0 passing through slots in said knife-blade upon clearerbar m, so as to be djustable, substantially as described.'
