WILLIAM T. HOSE, OF NEW YORK, N. Y., ASSIGNOR TO EMIL S. LEVI, OF SAME PLAGE.

MACHINE FOR MAKING RUCHINGS.

SPECIFICATION forming part of Letters Patent No. 246,011, dated August 23, 1881.

Application filed June 8, 1881.

To all whom it may concern: Be it known that I, WILLIAM .I. HOSE, of

the city and county of New York, in the State of New York, have invented certain new and useful Improvements in Machines for Making Ruchings, of which the following is a specification.

My invention relates to machines for making ruchings, in which the iiuting of the strip of fabric from which the ruchin gs are produced is performed by intermeshing endless chains.

rIhe invention consists in the combination,in such a machine, of two pressing-rollers, arranged one above the other, and between which a strip of fabric is passed, and which flatten and press the middle portion down, and two pairs ot' intermeshing chains arranged on opposite sides of said rollers for uting the marginal portions of the fabric while said rollers Hatten and press down the middle portion.

One serious diiculty heretofore existing in chaindiluting machines has been that the tintes become disarran ged and distorted by the withdrawal of the chain-blades from each other as they pass around the end chain wheels or rollers of the machine.

One object of myinvention is to obviate this diculty; and to this end the invention consists in a machine for making neck-ruchings comprising one or more pairs of endless intermeshing chains, which diverge gradually toward the exit end of the machine for the whole or a part of their entirelength, thus withdrawing the blades of the two chains from the iiutes of the ruching `before the chains pass over their wheels in returning` to the entrance end of the machine.

The invention also consists in novel means of varying the depth to which the blades of the two chains intermesh at the entrance end of the machine.

Theinvention also consists in a novel method ot' arranging the endless chains used in the aforesaid machine, and in details of construction to be hereinafter explained.

In the accompanying drawings, Figurel represents a longitudinal vertical section of amachine embodying my invention. Fig.2 represents a plan thereof. Fig. 3 represents a transverse vertical section upon the line w x, Fig. 2.

(No model.)

Fig. 4 represents a portion ot' the two chains at the entrance end of the machine, together with gearing for transmitting motion from one to another. Fig. 5 represents a perspective view ot' two of the blades or links of which the upper chains are composed; and Fig. 6 represents a perspective view of a portion of the lower ,chains of the machine.

Similar letters of reference designate corresponding parts in all the gures.

A designates the two side frames of the machine, which are connected by suitable stretchers, so as to form a rigid framing; and B B' designate lower and upper hollow drums, arranged one over the other, and adapted to rotate in suitablebearingsin the two side frames, A. The shaft of the lower drum, B, is mounted in fixed bearings; but the shaft of the upper drum, B', is mounted in movable bearings. upon which the ends of a spring, c, bear, and which are impelled downward by said springs.

Thetension of thespring a may be regulated by an adjusting-screw, O, which is tted in a nut formed in a yoke or cross-bar, A', as best seen in Fig. 3.

At about the middle of the length of the drums B B are portions B2, of considerably larger diameter, which may be made in the same pieces with the drums or be separate disks fitted and secured upon thedrums. The portions B2 rotate in face-toface contact, and Aconstitute rollers for iatteuing and pressing material passed between them.

Upon each side of the rollers B2 is a pair of intermeshing endless chains, by which the linting is accomplished, and which I will now describe.

D designates the lower chain of each pair and D' designates the upper chains, which intermesh therewithf In the present example of my invention the upper chains, `D', are of different construction from the lower chains, D; but this is done to show two methods of constructing the two chains, either of which may be employed, and both the upper and lower chains will, in practice, be of one and the same construction.

The form and manner of constructing the two chains are shown most clearly in Figs. 5 and 6, the former of which represents a por- IOO tion of the upper chains, D', and the latter a portion of the lower chains, D.

Referring first t0 the upper chains and Fig. 5, b designates the blades of the chain, which are provided on opposite sides at their lower edges with projectinglugs or ears b'bz. Thelugs or ears b' are at the extreme edge of the blade b, while the lugs or ears b2 are at a distance from the edge about equal to their thickness. Each blade b has on one edge lugs or ears b' and on the opposite edge lugs or ears b2, and when the blades are alternated the lugs or ears b' of one blade will tit upon the outside of the lugs or ears b2 of the adjacent blades, thus forming an interlocking series of links, which are secured together by pins or pintles passing through perforations or holes in the lugs or ears b b2.

Referring, now, to the lower chains and Fig. 6, b3 designates prongs or arms or bars, each having at its endlugs or ears b', which project on opposite sides thereof and have in them holes or perforations. The pins or pintles b4 employed in this case must have shoulders at the ends, which may be formed by reducing the diameter of the end portions or by slipping upon the pins small sections of tubing in a well-known manner.

In constructing the chain D, (shown in Fig. 6,) each link of the chain is formed by two bars, arms, or prongs, b3, and the lugs or ears b' on alternate links overlap the lugs or ears on the intermediate links and receive through them the ends of the pins or pintles b4. rlhe lower chains, D, of the two pairs are passed around and supported by the lower drum, B, a rotary bar or shaft, c, at the entrance end of the machine, and chain or sprocket wheels d, fixed upon a shaft, d', at the exit end of the machine, all shown clearly in Fig. l.

The requisite tension upon the chains is produced by moving the shaft d', upon which are the wheels d, bodily away from the drum B, and in order to provide for this I have represented the shaft d' as journaled in bearings d2, which may be adjusted along horizontal rods d3, projecting from'the frame of the machine, and which, when adjusted to proper position, may be secured to said rods by means of setscrews d4, as shown most clearly inFig. 2. The tightening of the chains D causes them to bear upon the under side of the lower drum, B, upon each side of its roller B2, as seen clearly in Fig. l. The endless upper chains, D', of the two pairs are arranged so that their blades b intermesh with the blades of thelower chains, and said upper chains are' passed around and supported by the upper drum, B', a rotary shaft or bar, e, near the entrance end of the machine, a second rotary shaft or bar, e', near the exit end of the machine, and wheels or rollers e2, fixed upon a shaft, e3, which is mounted and free to rotate in journals formed by or attached to the free ends of springs c4, which impart to said shaft e3 a constant outward and upward tendency.

The shaft c' is journaled in bearings c, which, by means of set-screws c6, may be pressed downward to cause the blades b of the chain D' to intermesh more or less with the blades of thelower chains, D. The proper amount of tension is imparted to the upper chains, D', by means of the shaft ci', carrying the wheels'e2, which press the chains upward and outward, and thereby cause them to be drawn over and pressed against the top ofthe upper drum, B', as best seen in Fig. l.

The bar or shaft e at the entrance end of the machine should be adjustable toward and from the lower chains, D, to cause the blades of the chains D' to intermesh more or less with the chains D at the entrance end of the machine, so as to form ilutes of the required depth, and to provide for such adjustment the said shaft or bar is journaled in bearings formed in the free ends of bars or links E, which are pivoted at f to the side frames of the machine, and are capable of swinging n p and down, carrying with them the bar or shaft e. The swinging bars or links E are automatically moved upward,when released, by means of springsf', (best shown in Fig. 3,) and are drawn against the force of said springs by 'means of adjusting-screws fz, provided with nuts f3, and passing loosely through the ends of said links or bars, and Xed in the frame of the machine, as seen in Fig. 3.

From the above it will be readily seen that by adjusting the nuts f3 the two chains ofeach pair may be made to intermesh more or less, as may be desired, to suit the depth of flutes to be produced.

One very important feature of my invention will be best understood by reference to Fig. 1, in which it will be seen that the relative distances of the bar or shaft c at the entrance end of the machine and the bar or shaft e' at the exit end of the machine from the lower chains, D, is such that the two chains of each pair gradually diverge from each other, and hence the blades of the two chains, in passing from the entrance to the exit end of the machine, intermesh less and less until, at the bar or shaft e', the blades ofthe upper chains, D', do not intermesh at all with those of the lower chains. This gradual withdrawal of the chains D' from the chains D is very important, because the blades of the chains D' are gradually withdrawn from the flutes of the fabric, instead of being suddenly withdrawn when passing around the shaft or bar e',A as would be the case if the two adjacent moving portions of the chains of each pair were parallel.

The distortion or disarrangement of the flutes where the blades ct' the fluting-chains are suddenly withdrawn from the fabric, as in machinesin which the two intermeshing chainsA are parallel, has heretofore been a great disadvantage in chain-iiutin g machines, and this objection to their use is overcome by my invention.

Turning, now, to the mechanism for impart- ICO IOS

ing motion to the several parts-of my machine, F designates a driving-shaft mounted in bear- Y ings transversely ofthe machine', and adapted them from the driving-shaft F by means of a pinion, F2, on said shaft, which engages with an idler, F3, that is in engagement with the wheel Gupon the shaft of the lower drum, B, as clearly shown in Figs. l and 2.

Upon the drivin g-shaftF are spur or sprocket wheels g, which engage with the pins of the lower chains, D, and thereby impart to them a positive forward movement. The blades of the chains D intermesh with those of the chains D, and as the latter chains are moved positively the former chains must also move correspondingly. In order, however, to make the movements of the two chains of each pair perfectly synchronous, I gear together the rotary bars or shafts c and e, which support the two chains of each pair at the entrance end of the machine, as clearly shown in Fig. 4. Upon the end of the shafts c and e are corresponding spur-wheels h, which are caused to rotate at equal speed by idler-wheels h', which are supported in swinging bearings h2, to cause them to keep in gear with the wheels 71, as the rotary shalt e is moved toward or from the shaft c, as previously described.

The portions/of the shafts c and e upon which the chains D D bear are made four-sided or square, with concave faces, to adapt them to the lugs or ears b of the chain-links, as seen in Fig. 4, or of polygonal form, with concave sides, as seen in Fig. l; and as the chains D are moved positively they will rotate the shaft c, which motion is transmitted to the shaft e, as previously described. The 4shaft e, being square or polygonal, will engage with 4 the chains D' and cause the latter to move in unison with the chains D.

The 4material to be fluted is fed into the machine over a bed or table, H, by means of feeding-wheels H', which are toothed to act effectively upon the material, and are fixed to a shaft, I, which is adapted to rota-te in bearings I' on opposite sides ofthe machine. Where the shafts over which the chains pass are foursided, as in Fig. 4, the blades of the chains afford a wider opening between them, and are adapted to receive a greater quantity of material than they would if said shafts had six sides, as shown in Fig. 1.

The sha-ft e' at the exit end of the machine has upon it a gear-wheel, J, which gears with and receives motion from a corresponding wheel, J', upon the driving-shaft F, as seen in Figs. 2 and 3. Upon the opposite end of the shaft e' is a large cone-pulley, J2, from which a belt, J3, passes to a corresponding pulley, J4, of smaller size, upon the shaft l. Motion is thus imparted to the feed-wheel shaft I, and to vary the speed of the feed-wheels and the entrance of material into the machine all that is necessary is to shift the belt J3 upon the pulleys J2 J 4 to get the desired speed.

In order to take up all slack in the belt J3 at all times, I make it of considerable length and carry it downward between the pulleys J2 J4 over an idler, K, which isjournaied in a weighted lever, K', which is fulcrumed ati, as seen clearly in Fig. 1.

In the operation of my machine the strip of fabric L, which has been previously creased or iiuted in a separate machine, is fed over the table H and under the feed-wheels H', by which it is carried forward continuouslyinto the machine. Upon the table H are guides M, under the edges of which the fabric passes, and by which itis guided laterally, and also under the feed-wheels H'.

rProjecting downward fiom the inner edge 0f the table H is an apron, H2, which is curved to conform closely to the path traveled by the lower chains, D, and which prevents the fabric from passing down under the said lower chains.

Ndesignatcs guides, which are shown as consisting of bent metal rods, secured atj in thcl frame of the machine and extending forward between the feed-wheels H' and between the 4chains D D', but just about on a level with the tips of the blades b of the lower chains, D. These guides hold the flutes ofthe fabric down upon the blades of the lower chains as they are formed by the intermeshing blades of the upper chains, as clearly seen in Fig. 'L The strip of fabric is additionally guided laterally by guides o, which are adjustable toward and from each other upon a transverse bar, O', by means of screws k, as best seen in Figs. 2 and 3. The fabric passes between the guides O, which should be adjusted to such a distance apart as will allow of its easy passage between them.

P designates gas-pipes leading to opposite sides of the machine to open air-chambers P', from which the mixture of gas and air passes upward through pipes P2 to the two drumsB B', in which it is consumed in properly-constructed burners, thus heating the drums.

lf desirable, steam might be used in place of gas for heating the drums. The fabric fed forward by the feeding-wheels H' passes between the chains of the two pairs, and is thereby fluted, while the middle portion is fiattened and pressed down by the rollers B2, thus producing a fabric having a dat middle portion and iiuted marginal portions, and which may be formed into neck-ruchin gs by dividing it longitudinally through the flattened middle portion and transversely to form proper lengths.

1t' desirable, paste-threads may be conducted between the rollers BZ and stuck to the attened middle portion of the fluted fabric, and in Fig. l I have represented paste-boxes l, from which threads covered with adhesive substance ma-y be conducted to the upper and un- IOO IIO

IIS

der sides ofthe fabric, and lpressed down upon the fabric by the rollers B2.

The paste-boxes and their appurtenances form no part of my invention. As clearly Ashown in Fig. l, the lower chains, D, ot' the two pairs are extended considerably beyond vthe upper chains, D, and I have arranged bc- Yform neck-ruchings.

By my invention I remove one great objection hitherto experienced in the use of chainfluting machines.

What I claim as my inventiomand desire to secure by Letters Patent, is-

1. In a machine for making ruchings, the combination of two pressing-rollers, arranged one above the other, between which the fabric passes, and by which the middle portion ofthe fabric is flattened or pressed,and pairs of endless intermeshing uting-chains on opposite sides of said rollers for luting the marginal portions of the fabric, all arranged and oper-- ating substantially as herein specified.

2. In a machine for making neck-ruchings, one or more pairs of endless intermeshing flutin g-chains, which diverge gradually toward the eXit end of the machine, substantially as and for the purpose specied.

3. In a machine for making neck-ruchings, the combination of pressing-rollers and pairs of endless intermeshing uting-ehains on opposite sides of said rollers, the chains ot' each pair being so arranged as to diverge gradually toward the exit end of the machine, substantially as specified. Y

In a machine for making neck-ruchings, the combination of one or more pairs of endless intermeshing uting-chains, a feed-table, feeding-wheels for feeding the fabric over said table between the chains, and means for varying the speed of said feeding-wheels relatively to the speed ot' said chains, substan tially as specified. Y Y* Y The combination, with a liutimg-chain, of a'rotary shaft, e, over which the chain passes, swinging links or bars E, pivoted at one end, f, and having bearings for said shaft at their other or free ends, and the springs f and adjusting-screws f2, for raising and lowering said links or bars and shaft, all substantially as specied.
