MACHINE FOR FINISHING LACE OR OTHER FABRICS.

SPECIFICATION forming part of Letters Patent No. 408,492, dated August 6, 1889.

Application filed November 29, 1887. Serial No. 256,462. (No modelJ Patented in England March 19, 1 1 and 1 temher 19, 1885, No. 11,152, and in France February 2, 1887, No. 178,809.

To all whom it may concern.-

Be it known that I, LEONARD LINDLEY, lace-dresser, a subject of the Queen of Great Britain, residing at Nottingham, England, have invented certain new and useful Improvements in Machines for Finishing Lace or other Fabrics, (for which I have received Letters Patent in Great Britain, No. 5,160, dated March 19, 1884:, and No. 11,152, dated September 19, 1885, and in France, N0.178,809, dated February 2, 1887,) of which the following is a specification.

The invention relates to that class of machinery employed in finishing lace and other fabrics in which the fabric is stretched in the direction of its width on endless chains of tentering hooks, pins, or clamps, and is delivered by them onto the first of a series of drying or ironing cylinders; and my present invention consists of a novel arrangement and combination of parts, whereby I obtain a simpler, lighter, and cheaper form of machine than heretofore, which permits of the ready introduction therein of the fabric to be finished, dispenses with a large amount of labor hitherto required in effecting such introduction, presents a clearer view of the fabric as it passes therethrough, is less liable to injure the fabric, and obviates the neces- Fig. 11 is a side View, and Fig. 12 is a plan,of

a portion of one of the endless chains used at each edge of the fabric. Figs. 13 and 14 are respectively a side view and a plan of one of the links thereof separately; and Figs. 15 and 16 are respectively a vertical section and a plan of parts, showing a slight modificatlon. Fig. 17 is a cross-sectional view of one of the rollers, showing the same covered with cloth, as hereinafter described. Fig. 18 is an enlarged detail View of parts hereinafter fully explained. Fig. 19 is a diagrammatic View of the first and last rollers in each of the series, illustrating the difference in size hereinafter referred to. Fig. 20 is a detail view of a modification hereinafter explained.

In all the figures like parts are marked with similar letters of reference.

a. is one of a pair of chains of tentering hooks, pins, or clamps which run in troughs or guides b 6 and pass over chain-wheels E2 by which they are caused gradually to move forward toward the first of aseries of ironing or drying rollers 0. One of these chains ais employed at each side of the machine, and the troughs or guides 19 b and wheels 19 carrying and giving motion to the same, are car ried by frames 1), which are provided with wheels 13 supported on cross ways or rails o in such manner as to be capable of being moved toward or from each other according to the width of the fabric under treatment, and the frames 1), and consequently the chains, are so arranged as to stretch the fabric to the desired extent before its delivery to the first of the series of ironing or drying rollers c 0*, which is driven at the same surface speed as the chains a by suitable gearing, as hereinafter described; Each frame I) has a leg or foot, as shown at Figs. 1, 2, and 18, in which are suitably journaled wheels I), having grooves which adapt them to run upon the cross way or rail b The ironing or drying rollers c 0* are heated by steam, which is supplied to them by pipes 0 passing axiallyinto them through stuffing-boxes c, and connected at their outer ends with a common steam-chamber 0 which, by a steam-pipe 0 provided with a suitable stop-cock, is connected with a steam-boiler.

c is a steam-gage attached to the chamher 0 to indicate the pressure of steam therein and in the rollers c.

The steam-chamber 0 as shown by dotted lines in Fig. 3, is of curved form corresponding with the curve in which the rollers c are preferably placed.

The large heated ironing or drying cylinder formerly employed in this class of machine required a separate steam-gage to be used therewith, on account of the difference heated rollers 0.

in strength between the same and the smaller By dispensing with such large heated cylinder 1 also dispense with the said separate steam -gage used therewith,and as the ironing ordrying rollers c 0*, are all of nearly the same strength a single pressure-gage 0 attached to the steamchamber 0 is all that is required on the machine. The ironing or drying rollers c 0* may, some or all of them, be covered with cloth or felt a: in the manner illustrated in Fig. 17, or they may be used without such covering.

The lowest of the series of rollers 'c is placed as close as possible to the chains a of tentering hooks, pins, or clamps, which deliver the fabric to be finished directly to such lowermost roller 0, and in order to maintain the chains a always within a given distance of the surface of the said lowermost roller 0, I cause each of the chains a to pass over a pair of rollers d d, carried at one end of an arm or lever b*, which is mounted on an axis b carried by the frame 12,.and such arm or lever 12 is acted on at one end by a spring L, which causes the rollers d d to be borne upward toward the lowermost heated roller 0. The links of the chains a pass over the roller (1, and the extensions a thereof, carrying the tentering hooks, pins, or clamps, pass over the roller d. I also attach to the chains a wood or other non-metallic blocks a a, which rise a short distance above the points of the hooks or pins a or it may be clamps, and the links a of the chains and these blocks a a are pressed against the lowermost roller 0 by the rollers d d, which latter support the chains a at such an angle as to facilitate the release of the fabric from the hooks, pins, or clamps a By these means the tentering-chains a are always maintained in the same relation to the lowermost roller 0, and the tentering hooks, pins, or clamps are prevented, by the wood or other non-metallic blocks a a, from catching against the said lowermost roller 0, or against the fabric thereon, while by the use of such non-metallic blocks a (4 ,1 avoid soiling such roller 0.

When adjusting the traversing frames Z) to a new width of fabric, each spring I) is unhooked from the arm or lever 0 at which time the smaller spring 11 which always remains attached to the opposite end of such arm or lever 1), acts to draw down such end, and consequently the rollers d d, thereby causing the blocks a a of the chains a to fall out of contact with the lowermost roller 0, and thus prevent injury to such roller or to the cloth or other covering thereon in the traverse of the chains in the direction of the length of such roller 0. This mechanism of course is duplicated at the opposite side of the machine, (not .shown,) and therefore the description of the one side just given will suffice for both.

In order to prevent contraction or distortion of the fabric operated upon when it is transferred from the tentering hooks, pins,

or clamps to the lowermost drying-roller c, I employ two endless chains 6 to act at the edges of the fabric to assist in liberating the fabric from the tentering hooks, pins, or clamps and to bring the edges thereof immediately into contact with the said lowermost roller 0. I also form such chains 8 with narrow bearing-surfaces e, so formed as to present an almost continuous bearin "-surfaee to the lowermost heated roller 0, and I supplement such narrow bearing-surfaces 6 with a bearing-su rface 6 formed upon the solid part of the links of such endless chains (2, and I preferably form such bearing-surfaces e e roughened, in order to enable them to obtain a firm hold of the fabric under treatment. These endless chains e are caused to remain in contact with the edges of the fabric and to press them against the heated surface of the lowermost heated roller 0 as far as possible around the same. For this purpose the endless chains 6 are mounted on chain wheels or pulleys f f f. The pulleys 01' wheels f f i at each side of the machine are each carried by an adjustable bracket b fixed to one of the frames b. The pulleys or wheels f are each carried by an adjustable bracket Z1, fixed to the top bar of the frame I), and the pulleys or Wheels f are each carried bya frame b, which is mounted with capability of sliding upon rods or bars Z), carried by the frame I), and such frame b is capable of being acted upon by a screw D When required to put strain on the endless chains 6.

The adjustable bracket 11 has its base formed in two parts 1 2, the lower part 1 being rigidly fixed by the wings 1 to the top bar of the frame I), and the upper part 2 being fixed to the lower part 1 by screws 3, passing through a slot in part 2 and screwing into part 1. The adjustable bracket 1) has its base formed in two parts 4 5, the lower part at being rigidly fixed to the upper bar of the frame Z) and extending over the trough I), while the part 5 is formed with a slot 6, through which screws 7 are passed, which screw into the part 4.

The pulleys or wheels f (see Fig. 18) are each carried by a pintle or axis 8, fixed rigidly to a bracket 9, which latter is adj ustably fixed to the frame 1) by bolts 10, passing through holes in the frame b and through a slot 11 in said bracket 9. This frame 11 consists of a broad flat member, as shown in Figs. 1 and 3, to one end of which is secured the member 5, in which the screw 1) engages, and at its other end is secured the pulley f in the manner above described. The said bracket 12 is supported by the bars I), while such bars are supported by the members 4, 12, and 13 from the main frame of the machine.

As shown, the screw 1) is provided with a hand-wheel 2 for operating it, and with collars or shoulders 3, which abut against both sides of the upright stationary member 4, while, as before remarked, its screw-threaded IIO end engages in the sliding member 5 of the frame 19 upon which the wheel f is mounted, thus causing the said frame Z9 to go and come on the bars I) when the wheel 2 is turned.

Motion is given to each of the endless chains 6 at the same surface speed as the chains a by an endless chain h passing partly around a chain-wheel I9 fixed on the axis b of the chain-wheel b giving motion to the tentering-chains a, and partly around a chain-wheel f, fixed on the axis of the chainwheel or pulley The ironing or drying rollers 0, according to the arrangement shown in the drawings, are arranged in two similar series, and preferably in an arc of a circle drawn around the axis g. Each of such rollers c or 0* is of slightly-greater diameter than the next preceding or lower roller 0 or 0*. This difference in size is very slight, and therefore hardly perceptible; but it is plainly shown in Fig.19 that there is considerable difference between the size of the first and that of the last roller of each series. As shown by dotted lines in this same figure, the first series c are all driven at the same number of revolutions by means of toothed pinions c and the second series of rollers 0* are driven at a slightly-accelerated speed by means of smaller toothed pinions fixed on the axes thereof, as represented in diagram in Fig. 19, all of which are driven by a toothed wheel g,

rotating on the axis g, which wheel g is' driven at the same surface speed as that of the tentering-chains a by the following means: Fixed to the wheel g and rotating therewith is a toothed wheel 9 which is driven by a pinion h, fixed on a shaft h, working in a bracket 3, fixed to the frame .9 of the machine. On this shaft h is a worm-wheel 71 which is driven by a worm c", fixed on the shaft 1', which latter is driven by a conespeed i on the same, to which motion is given by belting from any suitable source of power. v

For giving motioi'rt-o the tentering-chains u, a, driving-lever b provided with a pin b", is fixed on the shaft b and is driven by one of the arms of a wheel I), which in its turn is driven by a pinion h fixed on the shaft h. The wheel b is mounted loosely on the shaft 19 and by sliding it along the said shaft it can be disconnected from both the pinion 7L3 and the driving-lever I), when for any purpose the tentering-chains are required to be stopped.

By the above described arrangement .of parts the lowermost roller of the lower series of ironing or drying rollers c is caused to rotateat the same surface speed as that of the tenteringchains Ct, but on account of the increased diameters of the following rollers in this series the surface speed of each succeeding roller is slightly greater than that of the next preceding or lower roller, and also by the above means I cause the second series of rollers 0* to rotate slightly faster than the first, thus obviating the necessity for using so large a number of rollers of different diameters as would be required if they were all in one series of different diameters. In some cases, however, instead of using two series of such rollers only one may be used. The rollers 0 may, however, be all of the same diame ter, in which case the increased surface speed of each succeeding roller may be obtained by means of suitable gearing, the arrangement I prefer to use for such purpose being shown in Fig. 20, which consists of a separate toothed wheel g, to gear into the pinion c of each roller 0, such toothed wheel g and pinions 0 being so proportioned as to give to the said rollers c the required increase of surface speed.

By the use of ironing or drying rollers of gradually-increasing surface speeds I am enabled to efficiently finish cotton and other goods which are liable to extension on drying, as any extension of the fabric under treatment, after passing from the first ironing or drying roller, is taken up by the increased surface speed of the succeeding rollers, by which means it is kept in a constant tension until it is completely dried, thereby securing its continuous contact with the various rollers, and consequently producing a better finish than has heretofore been attained in the classes of goods which are liable to such extension on drying. When, however, it is desired to finish fabrics which are not liable to such extension 011 drying, I employ heated rollers which have all the same surface speed. I place outside and intermediate of these ironing or drying rollers 0 guide or conducting rollers j, which, by gravity, aided by suitable guides fixed to the framing is, carrying the bearings of such rollers 0, always remain in contact therewith.

The fabric is first placed on the tentering hooks,pins, or clamps in the usual way, and is conducted by the tentering-chains to the lowermost of the heated or ironing rollers c. The endless chains e assist in delivering the fabric to such roller 0 and then hold it firmly and as far as possible around the same. It then passes from such first roller 0 to and partly around a guide or conducting roller j, and thence to the second roller 0, and so on until it arrives at the last of the ironing or avoid the undue strain which is put thereon when using a large ironing or drying cylinder in combination with the rollers c, ashereinbefore described, which latter arrangement or combination necessitates the fabric to be conducted in a very circuitous coursethat is to say, first around the said large ironing or drying cylinder until it arrives at the uppermost of the heated rollers c, after which it is led around the said rollers c and guide or conduct-in g rollers j until it arrives at the lowermost of such rollers c, whence it passes partly around a guide-roller, and is thence caused to rise in a vertical direction to and over other guide-rollers to the back of the machine, where it is wound onto the winding-on drum or roller. I also, according to my present invention, by causing the fabric to pass through the machine in a continuously-forward direction, avoid the necessity of using the conducting-rollers hitherto necessary for conducting the fabric from the last or lowermost of the said rollers c backward to the winding-on beam or drum, as also the driving arrangements necessary for giving motion to such conductingrollers. I also avoid the necessity of using movable conducting-rollers for conducting the fabric from the large cylinder to the first of the said rollers c and for facilitating the entry of the fabric between the cylinder and said first conducting-roller.

\Vhen finishing some classes of fabrics, the tentering-chains will not be required, but the fabric will be passed over a breadthener-bar 02, (see Figs. 15 and 16,) or bars, roller or rollers, which will suitably extend it or smooth it out. When this arrangement is employed, the chain belts e are not necessary, but still they may be employed, if desired.
