SPECIFICATION forming part of Letters PatentrNo. 742,425, dated October 27, 1903. Application fled March 19-l 1903. Serial No. 148,467. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, ISHMAEL HEY, a subject of the King of Great Britain, and a resi dent of Lower Laithe, Oakworth, near Keighley, in the county of York, England, have in- Vented certain new and useful Improvements in Machines for Combing Wool and other Fibrous Substances, of which the following is a specification.

This invention relates to machines for combing wool and other fibrous substances, said machines being of the type known as Nobles combs. operations are primarily eected by one circular comb being rotated in tangential contact with another circular comb.

My invention consists in improved means l for forcing the Iibrous substances upon the pins or teeth of the circular combs, said means comprising loosely-mounted blades mounted upon bearings or supports which are adapted to yield to permit all of the blades to move entirely clear of the pins or teeth of the combs, substantially as and for the purposes hereinafter described.

My improvements further comprise devices for enabling the readjustment of the blades and their accompanying parts to be easily and readily effected. v

In the accompanying drawings, Figure l is a plan or view as seen from above of a sufficient portion of a combing-machine to show the applicationthereto of myinvention. Fig. 2 is a front elevation illustrating my improved parts as in their operating positions. Fig. 3 is a view of the parts shown by Fig. 2 as seen from above. Fig. 4 is an elevation, partly in section on line A B, of parts shown by Fig. 3 as seen in the direction indicated by the arrow m, all parts being in their respecti've positions as when in eective operation. Fig. 5 is a similar view to Fig. 4, but shows the parts in position as when thrown out of effective operation. Fig. 6 is an elevation of parts shown by Fig. 3, partly in sec-r tion on line C D, as seen in the direction indicated by the arrow y, the several parts being in their inoperative positions, as shown by Fig. 5. Figs. 2 and 6,inclusive, are drawn 5o to an enlarged scale as compared with Fig. l.

In such machines the combing- Similar letters and figures of reference in dicate similar parts throughout the several views.

The large and small circular combs are indicated, respectively, at a. and b. These and the feed-boxes c and the pillarcl of the framework are all of the well-known kind and operate in the usual manner. Secured to the pillar d is a bracket m, to which is fixed a support 7a2 for a lever lo, pivoted at lc' to said support. Secured to or fixed to the lever 7c' are bearings 72 having su pporting-pins g g g", upon Vwhich are mounted a series of blades, numbered l to 9, inclusive, said blades being adapted to force the wool or fibrous substance down upon the teeth e vand f, respectively, of the combs a and b. Also secured upon the bracket m is the lever p, pivoted at p p2 to said bracket, said lever being normally held against a stop-piece 'm' on said bracket m by va spring q. The lever p is provided with a projecting pin p3, entering a slot or opening las inthe lever la, thereby enabling the lever pto keep the bearings h and blades 1 to 9 in their proper working position against the usual vertical pressure of the iibrous subi stances. If, however, any hard cr foreign substance passes beneath the blades, so as to exert a force thereon-greater than the pressure of the spring q, said pressure is overcome and permits the lever p to rock, so as to spring it over to the position shown in Fig. 5, which is the position opposite to that in which it is shown in Fig. 4. A lever s, pivoted at s2 s3 to the bracket fm, is formed with .a space or recess s', which is engaged by a tooth p5 on the lever p, whereby the lever s is also moved from the position it occupies, as shown in Fig. 4, to the position in which it is represented 'in Fig. 5. It ywill now be readily understood thatthe spring q serves to hold the parts in the positions shown in Fig. 4 or in the position shown in Fig. 5 by the contractile force of said spring in one position serving to raise the lever 7c, the bearings h, and the blades carried thereby clear of the pins in the combs and in the other position acting to hold the bearings h down with suitable force, so that the blades will press the bers into the teeth of the combs.

IOO

A hook tis engaged/with the upper end of the spring and is formed with a knob t', which may be screwed thereon, said knob resting upon the top of the lever s, the hook extending through an opening therein. By means of the said knob t the tension of the spring may be adjusted as desired in order to meet the requirements of the fibrous substance under treatment.

The arrangement of the intel-engaged le- Vers and the spring is such that the movement from one position to the other and return may be very quickly effected, so as to cause the spring to exert its force on either side of the centers p2 and S3, as viewed in Figs. 4 and 5.

The rotary disks u u u2 are mounted upon spindles fixed to the rocking lever p, so that they also maybe raised thereby when the actions above described are brought about. In order that the driving belt or band us, which transmits motion to these disks u u u2, may not exercise any undesirable actions or force upon said parts, the driving-pulleys n n are arranged, as shown, in close proximity with the pivotal bearings 19'192 of the lever 19.

As all the blades l to 9, inclusive, are free to slide laterally on the rising of their bearings 7L, as above described, they might become disarranged upon their supporting-pins g g g, so that it would be difticult to replace them in their proper respective positions between the rows of pins in the combs cf, as shown. To obviate this, I mount appropriately forked or gridded pieces w and zu in bearings wz, secu red to a lever-arm w3, which latter has its outer end secured to a spring L04 by the adjusting or regulating bolt 105. By tightening the nut on this bolt the spring 104 is caused to exert an increased pressure upon an arresting-screw y, said screw being mounted in the arm lw3 and adapted to come in contact with a projection m2 on the bracket lm, so that when the blades are in their eective operating position, as shown in Fig. 4, further downward movement of the arm w3 is arrested. The spring 'L04 is secured to the pivotal end of the lever 7c, and the forked pieces w w are-adapted, when the parts are in the position shown in Fig. 4, to be held clear of the blades, so as to permit the latter to have lat-eral freedom of movement; but as soon as the bearings 71 begin to rise the prongs of the forked pieces enter the spaces between the blades, owing to the fact that the blades rise first, and thereafter lateral movement of the blades is prevented. After the rst npward movement all of the parts continue to rise together and retain their relative positions after the arresting-screw (1/ has moved entirely clear of the projection m2. When the bearings 71. are again forced down, as by the attendant pushing the knob t' backward toward the pillar d, the arresting-screw y comes in contact with the projection m2 in time to prevent the pieces w w from descending far enough so that said pieces w w/ would interfere with relative lateral movements of the blades.

Having now described the nature and object of my invention, what I claim isl. In a machine of the class described, a lever, bearings carried by said lever, a series of blades mounted upon said bearings and adapted to move laterally thereon, and an adj ustable spring device for causing the blades to exert pressure upon the fibrous substances.
