DABBING API ARA'TUS FOR WOOL-C(JMBING MACHINES.

SPECIFICATION forming part of Letters Patent No. 650,601, dated May 29, 1900. Application filed October 2, 1899. Serial No. 732,281. (No model.)

To aZZ whom it may concern:

Be it known that I, JoNAs DENBY, a subject of the Queen of Great Britain, and a resident of Oxenhope, near Keighley, in the county of York, England,-have invented certain new and useful Improvements in Dabbing Apparatus for VVool-Combing Machines, of which the following is a specification.

My invention relates to improved dabbing apparatus for wool-combing machines of the class known as Nobles combs; and it 0011- sists in producing, constructing, and arrangin g said apparatus so that the dabbingbrushes heretofore employed may be entirely dispensed with by the substitution of better, more durable, and efiicient devices.

In the accompanying sheets of drawings, which are illustrative of my said invention, Figure 1 is a plan view of a sufficient portion of a Nobles comb to illustrate the application thereto of my improved dabbing apparatus. Fig. 2 is a similar view to Fig. 1, but is drawn to an enlarged scale, and shows the dabbing apparatus on one side of the comb, that on the other side being identical with it. Fig. 3 is a sectional elevation of parts shown by Fig. 2 and as seen in the direction of the arrow 00. Fig. 4 is also a sectional view of parts shown by Fig. 2, but as seen in the opposite direction to that indicated by the arrow Fig. 5 is an elevation of parts illustrated by Fig. 2 and as seen in the direction of the arrow g Figs. 6, 7, and 8 represent an elevation, a sectional side elevation, and a sectional plan, (on line :r so of Fig.'7,) respectively, of the delivery end of a blast or blow pipe hereinafter'described and are drawn to a scale still larger than Figs. 2 to 5, inclusive. Fig. 9 is a detail drawing, same scale as Figs. 2 to 5, of one of the plates or blades mounted in the comb-circles, as hereinafter described.

Similar letters and figures of reference indicate similar parts throughout the several.

views.

In accordance with my said invention I mount, between the rows of pins 1 and 2 and those at 3 and 4 in the large comb-circle a, plates or blades 0, respectively, which will reach down from the tops of said pins to about their middle parts, while between the rows of pins 2 and 3 and those at 4 and on the said circle a. I mount other plates or blades (Z d,

Thus

will occupy alternate positions, while the course or path for the fibers beneath and above same will be somewhat of a zigzag form, as shown by broken lines, Fig. 4. I also preferably employ a blade or strip e, similar to those 0 c, and mount it to intervene between the pins 7 and 8 of the small comb-circle Z).

By the fibers being constrained to follow a zigzag path, as above described, they are held from being withdrawn at such parts from the large circle a by the lesser circle I), by which means said lesser comb b will only separate the shortest and least useful fibers therefrom, while when the large comb a has carried its fibrous substances beyond and clear of the retaining-blades c c and d 01 then the drawing-off rollers are enabled to freely pull same in the usual and well-known manner, thus to comb it between the several rows of the said combs teeth.

The blades 0, c, and e are mounted in their bearings f by their bolts or rods 9, g, and 9 so that they are enabled to have slight lateral play or side shake to allow them to accommodate themselves to any irregularities that the rows of teeth in the comb may have from their true circular paths, while further to allow the fibers or wool to be less firmly held at certain parts of their or its path under the blades 0 0', so that although still kept well within the interstices between the teeth it requires less force to be exercised by the small circle, I form the lower edges of the blades 0, c, and e, or any of them, of a serrated shape, as shown in Fig. 9.

To force the fibers or wool down and under the blades 0 c, I conduct a current or currents of air or a blast of wind through the pipes h and 71; to strike together said fibers or wool at that part of their path of motion just before reaching the curved ends of the blades 0 c, and this blast of wind I make to follow such a path that it will first extend in a thin current across the rows of pins in both of the circles, (or a part of same,) said part of the current passing through the orifice h'of the pipe it, while two other parts of the current are conducted to strike between said rows of pins through the parts 7L2 7L3 of the orifice in the same pipe and that with sufficient force to force the fibers or wool, as desired. The orifice of the pipe 70 is further arranged so that it may be adjusted to direct its current of air to commence the pressure of the fibers to bring them into better position to be sub sequently acted upon by the succeeding airblast.

Any suitable fan, blower, or air-propelling mechanism may be employed for producing the currents of air as described.

Such being the nature and object of my said invention, what I claim is V s 1. In a machine of the character described, including combing pins or teeth, an air-pipe for directing a current of air into the interstices between said pins or teeth and toward their bases;

2; In a machine of the character described, including combing pins or teeth, a flatmouthed air-pipe extending across the rows of pins or teeth for directing a thin current of with the pins or teeth thereof, of an air-blastv pipe for forcing the fibers downward between said pins, and blades for holding the fibers when so forced.

4. In a combing-machine, the combination with the pins or teeth thereof, of an air-blast pipe for forcing the fibers downward between said pins and blades for holding the fibers when so forced, said blades having serrated JONAS DENBY.
