IMPROVEHENT IN MACHINES FOR DRESSING AND FINIBHING THREAD.

The Schedule referred to in thou Letten Potent making part of the uma.

' To lall 'whom-it may concern:

Be it known that we, ORIGIN HALL, of the town of Willimau'tic, county of Windham, and State of Corr-` necticut, and TIMOTHY Mnnnrcrr, of Holyoke, in the county of Hampden, and State of-Massachusetts, both formerly of West ViIIington, in the county of lolland,

and State of Connecticut, have invented certain newv 'and useful Improvements in Machinery for -Dressing and Finishing Sewing-Thread, or other threads or yarns; and we do hereby declare thattlre ibllowing is a full, clear, and exact descriptionjofvthe saure, reference being had to the accompanying drawings, forming part ot' this speciucation, in which- Figure 1 represents a longitudinal vertical section, taken just within one ofthe side frames of a machine, exhibiting all our improvements.I

Figure 2 is a planrof the same.

Figure 3 is a transverse elevation of a the machine.

' Similar letters ofl reference indicate corresponding parts in the several figures.

portion of To enable persons skilled in the art to make and use onrinvention, we will proceed to describe its construction and operation A is the framingof the machine.

.B is the brush-cylinder, the ljournals of which areI fitted to turn inlsuitable bearings supported on the said framing.

O Ol O C are rollers, which conduct the thread as it comes from the size-boxes into contact with the brush-cylinder, said rollers being at equal distances apart near to the cylinders, and parallel therewith.

The sizing-apparatus is not shown, but a.l thread is shown in red color in figs. l and 2. s The rollers derive motion ii'om the friction of the thread passing in contact with them.

The threads pass under the roller C, over rollers C and O, and under O, and by that means each thread is caused toconre in Contact with the cylinder in three places, and to be operated uporrby the cylinder' three v gether by a train of shafts F G G and bevel-gears'a a.

b c c, that all may be operated sirnnltaneouslnb turning an endless screw-shaft, H, which gears wit r The several rollers O, O, C', and C" have, at regular and `suitable intervals apart, small grooves d d, to receive and guide the threads.

The threads are'lnot directed from the grooves in one rollerto the grooves in the same line in the next roller, but are passed to grooves either to the right or left, and hence are prevented from making a series of wet streaks in the brushes, and leaving other parts untouched, and thus bringing all parts of the brushcylinder into operation, and thus preventi'r'rg any part ofit from becoming wet or damp enough to interfere with the succss of the operation. This mode of directing the threads is illustrated in iig. 2.

The thread, in leaving one roller, is caused, by the action of the brushes at the next place of contact, to assume, between that roller and said place of Contact, a line parallel with the planes of revolution of the cylinderbut from said place of Contact tothe next roller, it takes an oblique direction, as. shown in'fig. 2.

The arrangement of the conducting-rollers in relation 'to the brush-cylinder, arid the oiiices of the grooves in the lsaid rollers,I are fully described in, and relate more especially to the Letters latent granted us,- bearing date August 7, 1860, and nurnbered 29,484 y I is the polishing-cylinder, having its journals -tted to stationary bearings, supported on the frame A;

said cylinder being made of metal, hollow, and is heated by steam, admitted through hollow journals, in the manner common to calender-rollers, and havirrgsmall well-polished grooves c e in its periphery, to

receive the threads, which are conducted to and in contact with the said cylinder, on their way from the brush-cylinder to the spools, or other oontrivances by which they are taken up. This cylinder is driven by a belt, f, t'roin a pulley, g, on the shaft of the brushcylinder, at such a velocity that its peripherical surface moves much faster than the threads passing over it, and by the friction of 4its rapidly-moving smooth surface upon the threads, which are not quite dry, when they arrive at it, riries'and gives them a beautiful polish or glaze.

By having grooves e upon the cylinder I, each thread will be kept separate, and rnoleor less accurately rounded, by contact under pressure, with the surfaces of the grooves, and at the same time a much larger propoltion of the surface of' the thread will be exposed to the action of the heat than`if the rollerswere plain.

. J and J' are a pair' of plain rollers, between which the threadsv pass on their way from the brush-cylinder B to the polishingscylinder I, the lowerv roller J being titted to statiouarybeangs in'standards K K, erectedy on the framing A, and the upper one, J', resting on J',

it is'drawn between them.

The upper roller J' has imparted to it a regular reciprocating longitudinal mot-ion, whilethe machine is in operation, by means of -a cam, L, (best shown in, tig. 3,) on a short shaft, M, fitted to rotate in a stationary box, some distance vbelow the rollers Jand J the said cani operating upon the lower end of a lever, N, which works on a fixed fulcrum, h, and whose upper end is forked, and fitted to a groove in the axle of the roller J'.

'lhe reciprocating motion thus given t-o the said roller J', whilc the lower one, J, has no longitudinal motion, causes the thread to receive a` rapid Trolling notion, while it is passing in contact with the surface oi' the polishing-cylinder, and this rolling motion of the thread causes every portion of its circumferential surface to be presented to the action of the surface of the cylinder.

The cam-shaft M is driven by a belt, a', from a pnlley, j, on a shaft, I, arranged below the polishingcylinder, said shalt P having another pulley, K, which receives the motion through a belt, I, from a pulley,

lnl, on the brush-cylinder shaft, which is the shaft tromwhich all the moving-pints of the machine derive motion, except the rollers, which are driven bythe action of the moving thread.

Q is a roller, which assists the rollers J and J' to conline the threads to the surface of the polishingcylinder, and conducts tlielhreads therefrom to the spools, or other contrivanoes, (not shown in the drawing,) on which they are taken up, said roller having its journalsl titted to bearings in two slides R It, which are fitted to guides in two standards S S, erected on the front end ot' the frame A A.

vrIhe slides R R are furnished.- with toothed racks, to gear -with pinions n fn. on va shaft, T, which works in fixed bearings in the standards S S, and the said shaft is furnished with a handle, by which it can be turned, to raise and lower the slides R R and ro'ller Q, to make the threads bear upon a lessor greater portion ofthe circumference of the polishing-cylinder, as may be desired. v

v N Ve claim as new, and desire to secure by LettersA Patent- 1. In combination with a brush-cylinder, the heated and rapidly-revolving metallic cylinder I, substantially as shown and described, for the purpose specified. l

2. I n combination with the hot polishing-cylinder,

the rollers J and J', and the adjustable roller, Q, or their equivalents, by means of which the passing.

threads may be forced orl actuated into a greater or lesser degree of contact with the surface of said cylinder, substantially as shown and described, for the' purposes specified.

3. In combination with the roller J, the vibrating lroller J,when arranged to operate in combination with a h'ot polishing cylinder, in a brush-cylinder machine, substantially as shown and described.

4. A heated metallic cylinder, having in its peripherical surface, grooves of a proper size, and well polished, in combination with a brush-cylinder, as and for the purposes specified.

In testimony whereof', we have hereunto subscribed on this, the 31st day ot August, A. D. 1869.
