Specification of Letters Patent No. 230, dated June 14, 183.7.

To all whom it may concern of the city, county, and State of New York,

have invented a new and useful Improve-v., ment in Machinery for Making a Batting or Web of Fur; and that the following is a full and exact description of the construction and manner of operating said machine as? i for supporting and moving the vellum, 'or

invented by me,-that is to say: f Y

Whereas certain machines called carding machines are well known and in use by vthe :manufacturers of cotton and wool, and other f fibrous substances and also certain machines 1 placed 'turns in boxes under the plates and Ais are known and used by hatters in conjunction with the carding machine for making hat bodies of wool, but these machines or.t any combination of them have not heretof` fore been known or used for making a continued batting, or web of fur; now my ma chine consists in the application of certain parts of such known machines, in combinav tion with other parts which have not here-l tofore been known or used in said machines,

the old and ynew parts being so arranged proportioned and combined as to produce a machine capable of making a batting, or

andk for other purposes; and for the more perfect explanation of my said machine reference is made to the drawingshereunto annexed, No. 1 and No. 2, where the several parts of my machine are distinguished from each other by letters of reference.

It commences with a common carding machine, with one main cylinder, with yits usual feed apron, its feed rollers, its licker in. The main cylinder marked, A, has a motion `of about 8O turns in a minute, and its workers, and strippers, its fancy, and doiiing cylinder., as represented around it in dotted lines,

all which is so common and so well known to.

mechanics as to need no `further description,

as it is in no way altered by mm-except bowing in the usual method, and for other Be 1t known that I, THOMAS BLANCHARD,

purposes, by the following machinery: the

#plates ofthe cardingmachine extendingV backfofvA the card supported in front by two legs and in the rear by being let into and so supported by two upright posts marked, 'J

and Lf; Vunder the whole of which, a frame or box is built close andtight. Two rollers ywire cloth apron, 0;, a, which rollers are marked D E, and are placed in their bearings as representedback of the card; one of Y the rollers on which the driving pulley C is marked D, the other roller which is marked E Ysupports the back section of the vellum y n and turns in boxes attached yto the upright posts and L, above the plates 'o-f the frame, said roller E, and under the plates roller D lay, (having their bearings as before described') horizontal and parallel to each other, and are at a distance 'of about five feet 5' apart, the back roller E elevated about one foot abo-ve the roller D. Around these rollers `moves like a feed apron said vellum, or wire cloth which is endless; between the upper and lower sides ofthe said vellum and 9 i;

extending nearly to the said rollers D and E is placed a stationary box (shown in section by the red lines b, b, and in perspective at Y) with the top open to receive the air that comes through Vthe fur and upper sideof the wire vellum; two holes are cut near each other through one of the plates of Vthe frame and through the side of the box opening into the space between the upper, and lower part of the vellum, these holesbein'g sufiiciently large for the air to pass, which is drawn Vby the draft of a` fan marked 1F, which 'fan is formed on a horizontal shaft,

having its inner bearing in a 'bo-X between the holes and sustained at the other end by a post or out rigger; outside of the fan en the shaft is the pulley to drive it marked G. The fan is formed with two heads or flanges about four feet in diameter made fast to the horizontal shaft about one foot apart; be-

tween said heads are aii'xed four or more fans or buckets, the inner end made fast to the four sides of the shaft extending-outwards as far as the outer edge of the heads or flanges and made fast to them; ,through upright post J and its upper end extending' upward and resting against the cams 0f the cam wheel K, the shaded part forming a series of inclined planes; which gives the motion one way and a spring, M, bearing against the end of the journal returns the motion in the opposite direction from the cam, thus making a reciprocal or vibratory motion, the said cam wheel K is made fast or formed on the inside of the pulley P; and when this, or the back part of my machine is thus formed, arranged and put together, and then inclosed, a vacuum or exhaust chamber is over the wire vellum into which the fur is thrown by the quick fancy; and then by exhaust-ing said chamber by suction, or draft, the fur is drawn tight upon the vallum, or wire cloth until it passes out with said vellum under roller I'I, which by its vibratory or tremulous motion hardens it into a web of suHicient tenacity to be handled and formed into hat bodies, or used as napping, the motion of the machine, is given by the main shaft O, which receives its bearings on the top of the upright posts marked J and L, and on one end of which is the pulley N, and on the other end the pulley l?, a belt passes from the pulley N to the pulley A on the main cylinder shaft, which gives motion to the carder. A belt on the pulley P to the pulley y gives an increased motion to shaft e and pulleys S and R. A belt from pulleys S conveys motion to a small pulley G on fan F. A cross belt from pulley R conveys a rapid motion to the pulley B on the shaft of the quick fancy, which throws the fur from the doffer into the exhaust chamber; a belt from pulley U on the shaft of the doffer conveys mo-t-ion to the pulley T, which, by a pair of gears conveys a slow motion to the driving roller (number one) of the feed apron; on the opposite end of roller one is pulley Q, which by a belt conveys motion to pulley C on the shaft of the roller D, which gives mot-ion to the vellum apron; a crossed belt on pulley, (number two), conveys motion to pulley X on the shaft of feeding card; pulley W receives its motion from a pinion wheel on the main cylinder shaft to a large tooth wheelqwhich 0 is made fast to the pulley W; on an out rig- 5 cards, (except the feed apron) the belts may.

ger, a belt from pulley W gives motion to the doffer over pulley V. When all these parts are thus arranged and the body of the machine inclosed tight, including all the be put on the several pulleys as represented; then pass a belt upon the driving pulley of the main shaft from the first mover, and all will be in motion. The fur will be received from the feeding apron by the feed rollers, and be carried by the licker-in to the main cylinder and passing all the workers and strippers it will be received upon the doffer, and by the quick fancy will be thrown into the air or exhaust chamber over the wire vellum and by the draft from the fan, drawingthe air out through the wire vellum, and by the progressive motion of the said vellum. The fur. is carried off as above de.

quantity of fur necessary to feed on the feed apron in a given time, but the speed and feed must be' governed by the thickness ofv the web required and different thicknesses of web required from different kinds of fur to be used for different purposes, consequently the alteration of the coperating parts of the machine may be varied according to the skill of the manager.

I do not claim any particular number of revolving fans toV exhaust the chamber of air. Although I have described but one on the one side of the chamber, two or more may be applied or o-ne on each side of the chamber when a more powerful draft is required; but it is necessary to regulate the draft in such a manner that the fur will be deposited equally on all parts of the vellum when a web of a uniform thickness is required, or a web may be formed thicker on one side than upon the other, or thickest in the center and tapering toward both edges; these variations may be effected in different ways; a board may be placed in the inside of the box under the vellum in different positions to break or change the current of air, as it passes through, which will cause the fur to deposit dierently on the vellum; pipes may be placed leading from the inside of the fbox that the air passing into them and out at one end may regulate the distribution, these pipes may be perforated with holes. The quick fancy that throws the fur from the doifer will raise suflicient current of air by its rapid motion to carry the fur to the vellum with the assistance of the draft of the fan.

I do not claim the fan as my invention nor the wire vellum apron, nor any part separately, but

I do claim as my improvement or invention- The forming the batting or web of fur by throwing the fur into a chamber and depositing it on an endless web of Wire cloth, or Vellum revolving around tWo extended rollers, and by exhausting said chamber of air by a revolving fan on the outside of said chamber, the air passing through the Wire cloth deposits the Vfur upon it 'and draws it tight upon the Wire cloth, at the same time the Wire cloth is forming its progressive motion, and carries the fur under a vibrating roller Which hardensjit to asulioienttenacity to be handled, and) formed into hat n bodies or used for naps, and the arrangement and combination of the above machinery and parts of'machinery in the manner above described and set forth and for the purposes aforesaid.

Trios. BLANCHARD.
