Speceaton'of `Letters Patent No.

.To all w-zfom t may concern.'

Be it known that I, FRANCIS A. CALVERT, of the city of New York, in the State of New York, have inventedcertain new and useful Improvements in the Manner of Goni structingMachines for `Coinbing Wool; and I do hereby declare that the following is a full and exact description thereof.

A principal improvement in this machine consists in the settingof the teethupon p denominated the combwheel, or ring, ,drawnr whichuthe wool isto be combed, on the inner rim of a vertical, flat ring, lor hoop, `which is without arms, so` that said teethmay point `toward the center `of said hoop; I am awareA that the merecausing ofthe teeth to point toward the center is not in`itself new,nnbut the setting them inthat'position onthe inner rim, or edge, of a `hoop without arms, is i new; and by this arrangement I am enabled to bring up a flexible comb belt, which` constitutes another of my improvements, and a clearer, or other analogous apparatus, on opposite sides of the vertical ring, so as ;t0` act upon the wool more advantageously than heretofore; a thing which in fact `could not be done wherearms were used. Another improvement `made by me consists in the manner in which I employ what I denominate backing rollers, by which rollers, `or some analogous device, I cause the long wool that collects on the comb teeth, and that lieson the back of the comb, to be carried down from a point above the `drawing rollers, so as tobe worked over again; by whichoperationthe great waste hereto-` fore resulting from the absence `of a device `of this kind, is prevented;

Another improvement consists in the sub-` stituting for the cOmbcyhnder, by whichthe `wool is taken fromthe feeding rollers, and delivered on to the teeth ofthe vertical comb` ring, a flexible `belt .of leather,or other-mate` rial, which is furnished with teeth, and passes around two rollers, one above the other, as hereinafter explained and repre-` sented. I have likewise introduced what I denominate an intersecting, toothed wheel which is so situated as to revolve between the teeth on the vertical comb wheel `and the drawing rollers. This wheel is furnished V withpointed teeth,and revolves ona center pin, but isnot driven by gearingof any kind, its motion being derived from that of the wool, as it passes up on `the teeth of the vertical comb wheel. This intersecting toothed wheel serves, very efiectually, to

n section through the 3,391, dated December e7, 1843;

prevent the nubs of wool from passing in between the drawing rollers, and causes `them to ascend with the long bers to the backing rollers, to be removed by the noiling roller. i `In the accompanying drawing, Figure 1,`

is a :front elevation, andFig. 2, a vertical middle, ofthe machine,

from front to back.

A, A, `is a vertical wheel, hoop, `or ring,

`to a scale of one eighth of the real size. This ring is sustained in its vertical position by means of grooved friction rollers, B, B

`stituted for thecomb` cylinder which has been hitherto used; and on to this the wool `is to be fed by a feeding apron, in the ordinary way of feeding machines for a like purpose; this feeding is not to extend to the whole width lof the belt, but only to such width as will leaveabout three inches toward each edge of the belt, free, or unfed.

` The ring A, Iniake `about siX inches` `wider, `and an inch and a half thick at its On its inner edge, where it` `outer edge. receives the teeth, it `is beveled on the sides,

n so `as to present a rim of about one fourthof an inch in width; Vthis form is shown at A in the section, Fig. 2.. E, is the clearer, which isfurnished with fancy card teeth, as usual.

`F, lF,.is a toothed belt that takes the wool as `it passes up on the comb teeth C, and delivers its ends `on to the `drawing rollers G, G, between which it passes, in straight lines, at rightangles to the plane of the ring,

A. A belt,A or a tube, is used to twist the wool as it passes from the drawing, tothe delivering, rollers, I, I; this is a wellknown device, and is not therefore, shown in the drawing.

What I denominate the backing rollers are shown at J, J. These, as beforeobserved,

. B to the two latter of whichI apply the are intended to cause the `long wool which collects on the comb teeth, and which lies onthe back of the comb, to be carried down, and worked over again. By these backing rollers, `which are madeyto revolve by suitable bands, or otherwise, the wool is passed from the teeth of the comb wheel, on to an and attached to the belt as represented at` N, N, that take the wool from a feeding apron of the ordinary kind, the situation of the feeding rollers being shown at O, O; from these, it is delivered on to the teeth C, of the comb-wheel, or ring, A. By the substitution of the flexible belt D, D, for the comb cylinder heretofore employed for feeding the wool on to the teeth of the comblwheel, a very important end is attained. The

belt D, while the feeding is effected by it, lies in the same plane with the teeth C, C, of the wheel A, and the feeding, therefore, is direct and uniform. The length of the comb cylinder formerly used, whether the part so called was made actually cylindrical, or whether it was curved from end to end on its face, had to be limited within bounds which it was desirable to exceed, but its extension was forbidden by the nature of the case. Under my arrangement no limit exists to the width of the flexible belt, excepting what arises from the actual diameter of the Y ring A.

I), is a noiling roller which is covered with leather, and serves to remove the noils from the teeth of the wheel A, after they have passed the backing rollers J, J.

Q, represents what I have denominated the independent, intersecting toothed wheel, revolving freely, as above remarked, upon a center pin; its pointed teeth passing through the space left between the teeth C, and the drawing rollers, such wheel being carried around by the wool on said teeth; its use is to prevent the nubs of wool from passing in between the drawing rollers, and to force them to pass up with the short fibers, to be removed and thrown under the machine by the noiling roller.

Having thus fully described the nature of my improvements on the machine for combing wool, what I claim therein as new, and desire to secure by Letters Patent, is-

l. Combining with the vertical wheel A, of a flexible comb-belt D, D, said belt passing around two drums, or rollers, and being therebyv made capable of delivering the wool on to the teeth C, in a direction corresponding with the plane in which they revolve.

2. I likewise claim the use of such a flexible comb belt, that is to say, having teeth formed on plates of metal, and attached to the flexible belt as shown at N, N, whether combined with the wheel A, or employed for a like purpose in any other combing machine.

3. I, also, claim the carrying down of the long, and other, wool, which has not been taken olf by the drawing rollers, to be worked over again, this being effected by the backing rollers J, J, and the toothed belt K, the latter reconveying it to the flexible belt D, to be worked over again. And I will here remark, that the manner of arranging this part of the apparatus as herein described, and represented in the drawing, is adapted to the particular kind of machine in which it is employed; but the same principle may be applied, by equivalent means, to other combing machines; such, for example, as that known as Simpsons belt machine, as well as to those of other constructions.v All that is necessary being to vary the arrangement of the parts in a manner which can be readily done by any competent machinist to whom the principle is known, without Vhis having a right to claim any new invention. I intend, therefore, in claiming the use of the backing rollers and belt, for the purpose set forth, not to limit myself-to the particular arrangement herein made known, but to embrace in said claim all variations thereof that are substantially the same in the manner of operating, and in the end attained.

4:. Lastly, I claim the manner of arranging and using what I have denominated the independent, intersecting toothed wheel, for the purpose herein fully set forth.
