To all whom it 71mg concern:

Be it known that we, SETH ORMONDROYD, machine -broker, a resident of Bradford, (whose post-office address is Leeds Road, Thornbury, Bradford) and JOHN FRANCIS \Vi-IITE, machine-maker, a resident of Bradford, in the county of York, England, (whose post-oflice address is 15 Oakroyd Terrace, Manningham, Bradford,) subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements in \Vool-Combing Machines, Gill-Boxes, and the Like, of which the following is a specification.

This invention relates to improvements in or in connection with the drawing-off rollers of the Noble type of wool-combing machines and to the similar class of fluted rollers of gill-boxes and like machines, the object being to provide an improved arrangement for mounting the rollers and foradjusting them nearer to or farther apart from one another at each end simultaneously or separately, the said arrangements being particularly adapted to enable one of the side frames or top frames supporting the bearings for the rollers to be easily and readily removed when required without in any way affecting the adjustment of the parts when they are assembled together again. In the case of the Noble combing-machines and gill-boxes the improved arrangements enable the usual leathers or aprons passing round the rollers to be readily removed and renewed.

A further feature of the improvements is to prevent undue wear on the leathers and to enable the fibers in the case of gill-boxes and like machines to be drawn in an even manner across the full width of the sliver as the latter leaves the combing-fallers.

The invention will be fully described with reference to the accompanying drawings, which show the application of our invention both to combing-machines and gill-boxes.

Figure 1 is a side elevation of a pair of fluted drawing ofl' rollers to which our improvements are applied in a Noble type of combing-machine; Fig. 2, similar elevation, partly in section, and Fig. 3 plan. Fig. 4 indicates an elevation, partly in section, of the fluted delivery-rollers of a gill-box or like machine; Fig. 5, plan of same, and Fig. 6 end elevation. Fig. 7 is a side elevation, to an enlarged scale, of the means for coupling the roller-adjusting shaft together; Fig. 8, end elevation of same; Fig. 9 side elevation, partly in section, at right angles to the view shown in Fig. 7, indicating the joining parts separated. Fig. 10 is a side elevation of an modified coupling arrangement to that shown in Figs. 7 to 9; .Fig. 11, end elevation of same; Fig. 12, sectional elevation of same, and Fig. 13 a still further modified construction of the coupling arrangement.

In carrying out our invention and referring more particularly to Figs. 1 to 3, (t represents bearing-brackets attached to the combingmachine in the usual way. These brackets are usually made with a fixed bearing in the ends in line with the main body of the brackets and in consequence the brasses or bearingblocks for the movable fluted .roller have to be made very thin at that side nearest to the roller in the fixed bearing, and as a consequence the draft of the wool or other fiber in passing through the rollers has a tendency to pull the bearings out of alinement or to wear the holes in them elongated, so that the flutes or grooves of the rollers instead of remaining parallel to each other, as is required for good work, are pulled to a slight angle with each other and are not in that condition as efl'ective as should be the case, while being out of alinement they also tend to cut and destroy the drawing-off leathers, as the pressure upon the latter is unequal. Under this arrangement it is not possible to give the bearing blocks su'flicient bearing-surface to resist the tendency to wear, as just described, and to overcome the defects we carry the first fluted roller 1) in bearings 0, preferably formed on the under side of the brackets a, such bearings being hushed, if required. The bearings for the second fluted roller (Z are loose, as shown at e, and are capable of sliding over the bearin s c to permit of the flutes of the rollers being dorought quite close together, if required. The lower bearings e are provided with extension-pieces e, forming a fork which passes round the roller b, the bearings being kept in position vertically by flanges e, which rest on the brackets a. The extensionpieces 6 entirely prevent the roller (Z getting out of parallelism with the roller 6, as they form extended and enlarged bearingsurfaces.

the back. of the bearings e and pass through slidable nuts as usual, springs g, surrounding the rods f, bringing pressure to bear on.

the nuts, as will be wel understood. At the outer ends the rods f instead of being passed through circular holes formed in the end brackets a are made square and passed through a flanged bush h, which is turned on its exterior to fit a hole formed in the end of each bracket a. The squared ends of each rod extend a little beyond the outer ends of the bushes in order to allow of the screws being turned for adjusting the pressure of the springs d. When such adjustment has been made the bushes can be locked in position by set-screws h; but the rods f are free to have longitudinal movement through the bushes in accordance with the thickness of wool or other fibers passing between the rollers.

With the exception of the arrangement of the bearings for the rollers b and d the arrangement of screws as applied to the gillbox indicated in Figs. 4 to 7 is the same as that indicated in Figs. 1 to 3. The bearings are of the usual construction.

Like letters in all the figures from Figs. 1 to 6 indicate similar parts.

The adjusting arrangements in both the combing-machine and gill-box are designed to enable both the rods f to be turned simultaneously. Our arrangements consist in the employment of a light shaft '5, capable of being readily connected and disconnected by the means to be afterward described. This shaft is provided with worms 'i and is journaled in bearing-brackets i, capable of being secured to and adjusted on the brackets 11. by means of set-screws a or the like. In the case of the combing-machine the shaft passes through slots a in the brackets a, while in the case of both machines the worms 4/ engage with teeth either formed on the bushes h, as indicated in Fig. 3, or with separate worm-wheels h, mounted on the rods f. The shaft i may be rotated by any suitable means, such as a winch handle or wheel indicates a cross-rail for connecting the two bearing-brackets a together. In the combing-machine this cross-rail is secured to the brackets a by set-screws b, so as to enable it to be readily disengaged from the top bearing-bracket a. In the gill-box the rail 6 5 is jointed at a suitable position in any suitable manner, but preferably by dividing it into two parts at c and connecting them together by a plate 0 and set-screws c.

As part of or in combination with the adjusting mechanism previously described We arrange the shaft t to be readily disconnected, so as to enable one of the bearing-brackets a to be readily removed bodily. The means we employ are of a simple character and may be carried out in several different ways. In Figs. 7 to 9 one portion of the shaft "L is provided with a central hole k, while the other is shouldered down to form a pin k, adapted to fit in the hole, thus giving perfect axial alinement to the shaft when connected. In order to convey the rotary movement given to that portion of the shaft provided with the handwheel to the other ortion, we slot one part of the shaft at Z am? cut away the other portion at Z, thus leaving a central portion Z,

adapted to fit the slot. The ends of the shaft may be provided with several slots and corresponding portions to fit into them, respectively, cut in different directions across them, thus forming a claw-coupling. In Flgs. 10 to 12 We have indicated this principle in a modi-v fied way by keying on the ends of the shaft fianged bosses m, one of which is provided with projections m while the other has anumber of slots m, both designed to engage with each other when the shafts are brought together, as will be readily understood from the drawings. In this case the end of one portion of the shaft projects through one of the bosses a little, while the end of the other por tion of the shaft does not quite come through its corresponding boss, so that axial alinement may be obtained in a somewhat similar way to that indicated in Figs. 7 to 9. In Fig. 13 we show the two portions of the shaft t cou led together by flanged bosses, through whicfi bolts are passed. For alinement purposes the ends of the shaft are arranged in a similar way to that shown in Figs. 10 to 12. By arranging the shaft '5 in the manner indicated one portion of it can be turned, after being disconnected, so as to advance or Withdraw the corresponding screw f, thereby enabling each bearing to be adjusted separately if required, and yet giving facility for adjust-. ing both bearings simultaneously when the parts are connected together.

What we claim as our invention, and desire to protect by Letters Patent, is-

1. In a combing machine of the Noble type the combination of parts for mounting and adjusting the drawing-off rollers consisting of bearing-brackets provided with extended bearings beneath the brackets, slidable bearings mounted in the brackets and movable across the fixed bearings, screws engaging with the rear of the movable bearings at one end and provided at the other with squared ends, bearing-bushes engaging with the squared ends of the screws rotatably IIO mounted in the ends of the bearing-brackets, nuts mounted on the screws, springs sur rounding the screws and abutting a ainst the nuts and bearing-bushes, a divisibIe adjusting shaft, worms mounted on the shaft, worm-wheels mounted on the adjustingscrews and means for rotating the divisible shaft substantially as described.

2. In a gill-box or like machine the combination of parts for mounting and adjusting the fluted rollers consisting of ordinary bearings two of which are fixed while two of which are movable, screws engaging with the rear of the movable bearings at one end and provided at the other with squared ends, bearing-bushes engaging with the squared ends of the screws rotatably mounted in the ends of the bearing-brackets, nuts mounted on the screws, springs surrounding the screws, and abutting against the nuts and bearing bushes, a divisible adjusting-shaft, worms mounted on the shaft, worm-wheels mounted on the adjusting-screws and means for r0- tating the divisible shaft substantially as described.

In testimony whereof we have hereunto set our hands in the presence of two witnesses.
