To all whom t may concerm- Be it known that I, VILLIAM LUND, a subject of the Queen of Great Britain and Ireland, and a resident of Philadelphia, Pennsylvania, haveinvented certain Improvements in Wool-Combing Machines, of which the following is a specification.

My invention consists of improvements in that class of wool-combing machines of which the Noble machineis an example,and in which the fiber to be combed is pressed into the teeth of a fixed ring and a revolving ring by means of a reciprocating dabbing-brush.

The objects of r'my invention are to equalize the wear upon the brush-reciprocating devices and to simplify and cheapen the construction of the same and of the brushes.

In the accompanying drawings, Figure 1 is wool-combing machine to illustrate my invention; Fig. 2, a front view, partly in section, and Figs. 3, 4, 5, and 6 detached views of parts of the machine, illustrating features of construction.

V.A represents part of the lixed frame of the machine; B, part of the hollow steam-heated ring, and D, part of one of the inner rings of the machine, both of these rings having proj ecting teeth ct upon the top, andthe parts rbeing otherwise constructed as usual in ma chines of this class.

Secured to theframe'A is a column or standard, F, which carries the bearings for the brushreciprocating devices.

The dabbing-brush is made in two sections, G G, each having a stem, b, and these stems are guided in sleeves or boxes d at the outer ends of upper and lower arms, f, the latterbeing secured to and projecting from the column or standard F. The upper armsfcarry bearings g for the operating-shaft I, which has a pulley, h, for receivinga driving-belt from any suitable counter-shaft, said shaft I being retained in position longitudinally by means of collars It. Y.

Keyed or otherwise secured to the shaft I is a disk, H, and secured to or forming part of this disk are two eccentricsJ J, set opposite to each other-that is to say, on opposite sides of the axis of the shaft-the strap K of one eccentric being connected to a collar, z', on the stem b of one of the brush-sections G, and the strap of the other eccentric being likewise connected to a similar collar on the stem of the other brush-section, so that as the shaft I is rotated a reciprocating movement will be imparted to both sections,vone rising as the other descends.

Plates m, secured to the`eccentrics, overlap.

the eccentric-straps K, and prevent the accidental detaching of the same, and the collars t are confined between nuts n on threaded portions of the stems b, whereby said stems and the brush-sections carried thereby can be adjusted vertically, as desired.

In order to permit ready adjustment of the brush-sections and their ready application to or removal fromthe operating-stems b, each of the latter carries at the lower end a grooved plate, M, for the reception of ribs w on .the back of the brush-block N, these ribs forming an undercut slot, p, for the reception of thel mechanism for operating a Ysingle dabbing-V brush, the eccentrics being set opposite to each other, so that one brush descends as the other rises. The brushes thus act alternately upon the wool at opposite sides of the machine; hence the: strain comes first upon one end of the long operating-shaft and then upon the opposite end,.thus tending to interfere with the steady driving of said shaft, andto cause torsional strain, to counteract which the shaft must be made excessively heavy. In carrying out my invention, therefore, in place vof single dabbing-brushes at each side of the ma-y chine, I use the dabbingbrush made in sections, acting alternately, as described, so that the strain upon each section is reducedto onehalf of what it would be upon the whole brush, and brush-sections at each side of the machine are acting simultaneously. Even if a` single operatingshaft for the brushes at both sides ,of the machinewere used, therefore, the strain upon the opposite ends of said shaft would be IOO equalized. For operating the brush-sections of my improved machine, however, the short shafts, each carried by bearings upon one of the pillars of the machine, and each having the operating eccentrics centrally-arranged thereon, as shown and described, are preferred, as such short shafts are more economical than the single long shaft, because their aggregate length is less, and because the two ecccntrics form practically one structure, so that they cannot cause uneven strain on the shaft, which, in consequence, can be made lighter than the single long shaft. By my invention, also, I am enabled not only to equalize the wear of the parts which operate the brushsections, but I am also enabled to cheapen the latter, as the small sections which I use are mnchless expensive than thesingle large brush heretofore employed. Moreover, when the irst brushsection becomes worn it may be renewed without renewing the second brush-section; or the latter may take the place of the first,and a new second section may be supplied. By first brushsection77 l mean that section which rst acts upon the wool enteringr the machine, this being usually the right-hand section shown in the drawings.

It will be evident that crank-pins on the shaft I may be used in place of eccentrics, if desired; but the ecccntrics are preferred.

I claim as my invention- 1. The combination of the toothed rings of a combing-machine with a dabbing-brnsh composed `of sections working side by side and with means for reciprocating said sections, whereby they are caused to act alternately, all substantially as specied.

2. The combination of the column F of the machine, a dabbing-brush composed of sections located side by side, ashort driving-shaft having bearings carried wholly by said column, eccentrics on said shaft, and mechanism, substanti ally as descrfibeclvhereby the movement of said eccentrics is imparted to the sections of the dabbi ng-brush, all substantially as specified.

8. The combination of the dabbing-brush, composed of sections located side by side, a driving'shaft, a pair of eccentrics forming a single structure,means for securing said structure to the shaft, and mechanism whereby the movement of the eccentrics is transmitted to the sections of the dabbing-brush, all substantially as specified.

4. The combination of the stem liavinga grooved plate at the lower end, the slotted brush-block having a portion adapted to said lgroove, and confining bolts and nuts whereby the brush-block is secured to the plate, all snbstantially as specified.

In testimony whereof I have signed my name to this specilication in the presence of two subscribing witnesses.

\VILLIAM LUND.
