SPECIFICATION forming part of Letters Patent- No. 416,641, dated December 3, 1889.

Application iiled J' une 24, 1884. Serial No. 135,895. (No model.) Patented in England November 20, 1880, No. 4,815, and March 17, 1885, No. 3,450; in France May 20, 1881, 110.142,98); in Belgium May 28, 1881, No. 54,712, and in Austria-Hungary September 6, 1881, No. 40,569.

To all whom t may concern:

Be it known that we, GEORGE HENRY NussEY and WILLIAM BEADSHAW LEACHMAN, subjects of the Queen' of Great Britain, both residing at Leeds, England, have inventedy new and useful Improvements in Machines for Tentering, Pressing, and Finishing Woolen or other Voven or Felted Fabrics, (for which we have obtained Lettersv Patent in 1o Great Britaimdated November 20, 1880, No.

4,815, and March 17, 1885, No. 8,450; France,

dated May 20, 1881, No. 142,939; Belgium, dated May 28, 1881, No. 54,712; Austria-Hungary, dated September 6, 1881, N o. 40,569,) of which the following is a specification, reference being had tothe accompanying drawings.

Our invention relates to machines for tentering, pressing, and finishing woolen or other woven or felted fabrics.

Our said invention is partly designed to iin-1 prove the construction of the machine de-;

scribed in the specification of English Letters Patent, dated November 20, 1880, No. 4,815.A

it, as hereinafter described. In finishing it is necessary that the cloth or other material should be twice crabbed-that is to say, it must be wound upon a crabbing-roller or perforated copper cylinder closed at one end, i and must then be treated by blowing steam through the said roller or cylinder and through the cloth or other material. The cloth or other material is usually wound on the said roller f first from one end and then from the other end, because the part next the cylinder receives more finish than the part at or near the exterior by reason of the heat of the said cylinder, the steam havingl a tendency to coning and washing the material, andA to finish dense toward the exterior. This treatment 5o renders woolen fabrics rather tender, as they have to remain on the crabbing-rollers for a considerable time; but by our invention we obviate the necessity for this treatment, as the cloth is finished by pressure between the hot plates on its passage through the machine, so that every yard or so of the cloth'is pressed and finished separately. 1f much luster is required, weincrease the heat of the plates, so as to fasten the face of the material. We 6o thus dispense with the boiling or blowing of the material, as usually practiced.

Our improved machine is illustrated in the accompanying drawings, in which- Figure 1 is a plan, and Fig. 2 a side eleva- 65` tion, of the said machine. Fig. 3 is an end elevation of the same, part-ly in vertical section, on the line a: 0c, Fig. 2. Fig.- 8 is an end elevation, drawn to an enlarged scale, showing details of construction. Fig. 3 is a side 7o elevation showing details of construction. Fig. 4 is a plan; Fig. 5,.avertical section, and Fig. 6 an edge View, showing details `of construction. Fig. 7 is a transverse section, and Fig. 8 a vertical longitudinal section, showing 7 5 parts of the said machine. Fig. 9 is a side elevation of a receiver, hereinafter described, for heating air. Fig. 10 is a transverse section of part of the said receiver.

a is a driving-pulley, which imparts motion 8o to the shaft a. This shaft is provided with an endless screw or worm a2, which gears with a worm-wheel 5*, fixed on the shaft b". The said shaft also has fixed thereon the cam b, which operates the valve of a steam-cylinder c by means of the lev'er d. The pressure in the cylinder c is utilized directly for actuating the pressing-plates, as hereinafter described. d3 is a loose pulley, which is fitted to rotate upon the shaft a.

The mechanism for driving the chains and drawing the cloth through the machine is constructed as follows-that is to say: e is a driving-pulley, which is fitted to rotate upon the shaft 6*. e is a conical piece keyedv upon 95 the shaft 9*, but free to slide thereon and fitting into the pulley c, soas to form there'- with a friction-clutch. The piece e is fast to a pinion f, Fig. l, which'is geared with a toothed wheel f', fixed upon a shaftfz, on which is also fjXed a bevel-pinion f3, geared with a bevel-pinion f4, fixed on a vertical shaft f5. On the lower end of thev shaft f5 isfixed a Vbevel-pinion f, which is geared with a bevel-pinionfl, fixed on the shaft f8. Abevelpinion f is also fixed on the shaft f8, and is geared with a bevel-Wheel flo, fixed on the shaft fu. The shaft fu is connected with the shaft f12 at the other end of the machine by means of the toothed wheels fl fm and the intermediate wheel f 15. Chain-wheels C C are fixed on these shafts for driving the chain B B 'B2 B3.

g isa forked lever for putting the said friction-clutch in and out of gear. This lever is pivoted at gk, and is provided with an adjnstable'piece g, having an inclined face g2.

h is a bracket attached to the cross-head z', which is formed or fixed on the rod c of the piston that works in the cylinder c. This bracket is provided with an anti-friction roller 7i', andis arranged to act like a tappet and operate the lever g in each upstroke of the cross-head t', so as to throw the friction-clutch out of gear and thus arrest the passage of the material through the machine while it is being pressed. A weight g3 is suspended from the lower end of the lever g by means of a Chain g1 passing over a pulley g5. The weight qS is fittedto slide up and down upon a guiderod gG. AA spring gT is attached to the frame of the machine and presses outward against the lower end of the lever g, so that when the weight g3 isxraised by hand, as hereinafter described, the said spring will operate the said lever and throw the clutch e e out of gear.

E is a lever or arm which is fixed upon a rock-shaft e2, carried in bearings in brackets E'i, secured to the base-plate of the machine. The rock-shaft e2 also has fixed thereon a forked arm E for shifting the belt from the fast pulley a to the loose pulley CL3, and vice versa, and lan arm- E2, which is connected by a rod E3 with the bent lever F. The horizontal arm of the lever F extends beneath a ange or nut gS on a rod g, secured to the weight g3. By these means the said weight may be lifted by hand and the clutch e e thus thrown out of gear bythe same movement that opens the valve' of the cylinder c to admit steam for effecting the pressing of the cloth or other fabric.

To permit the adjustment of the chains and the pressing-plates according to the width of the material to be operated upon, we provide a hand-Wheelj, fixed on a shaft j', which is carvried in bearings in brackets attached to the 6o` frame of the machine and on which are also fixed the bevel-wheels lo k 7a2. These bevelwheels are geared with other bevel-wheels Z l Z2, fixed on the screw-threaded shafts m m m2 for adjusting the chains or regulating the distance between the same.

For the sake of brevity we will only describe the construction acted upon by one of the shafts, as m2, it being understood that the others are similar.

rlhe shaft m2 is free toV rotate when the shaft j is operated, but is held from endwise movement. It is screwed into a cross-bar m3, Fig. 3, the ends of which are fitted upon the hubs of the chain-wheels C, and are secured thereon by means of collars C2. The said chainwheels are keyed upon the shafts fu f1?, so that they will rotate therewith, but they are free to slide thereon, so that they may be adjusted by turning the shaft m2 in one or the other direction. f

The shaft j has fixed thereon a wormwheel n, which gears with another worin- Wheel n', whose axis is at an angle to that of the worm-wheel n. The worm-wheel n is screw-threaded internally and is fitted upon a screw-threaded shaft o. The worm-wheel n is free to rotate upon or about its axis; but endwise movement thereof is prevented by the two arms or prongs of a forked bracket a2. Therefore when the shaft j is turned in either direction a corresponding longitudinal movement will be imparted to the shaft o by the worm-wheelornut'n. The screw-threaded shaft o is secured to the adjustable portions p p p2 p3 of the pressing-plates, the other portions p* 13'* p2* p3* of which are secured to the steam-chambers q, hereinafter described. Both the adjustable and stationary portions of the pressing-plates are of substantially the shape of a right-angled triangle with the hypotenuse of the one abutting thehypot-enuse of the other. Therefore when the shaft j is rotated the 4portions p p 192193 of the pressing-plates will be moved diagonally in one direction or the other, according to the direction of rotation of the shaft j', and can be thus adjusted to increase or diminish the width of the pressing-plates.

By referring to Fig. 7 it will be seen that the endless chains for carrying the cloth run in the channels formed between the ends of the pressing-plates and the standards supporting the plate r. In said drawing the numeral 5 indicates the cloth held by its selvage by the chains B B B2 B3. The action of the chains in pressing against the ends of the movable plates P P P2 P3 is to keep the contiguous edges of the said plates always in contact with the corresponding fixed plates The plates P P are held together by the filling-blocks P5, as shown in Fig. 4, said filling-blocks having bolts or riv- IOO IIO

ets passed through them. So, also, are the with a steam-boiler by means of the pipe q', shown in Fig. 4, and a pipe q2- is provided vas for the egress of the steam. fr, Figs. l and 3, is a fixed plate, whichis fiimly secured to the frame of the machine..

Each pair of pressing-plates,together with the chainberq between them, rests under normal conditions upon ledges or projections pi` (See Figs. 7`

on the'frame of lthe machine.

and 8.) The piston in the cylinder c is then at the bottoni of its stroke; but the said plates are free to rise when acted upon by the said piston.

The material to be tentered, pressed, andl the tentering-chain, and while held by the list or selvage on each side a portion of it is pressed between the plates r and p pi'. After being thus pressed for a few seconds it isl again diawn forward by the chains B, and another portion is similarly pressed,-and so on.

is again pressed between the plates p 19'* and p2 pw, while carried by that part ofthe chains marked B.

and is again pressed thereby.

the chains marked B3 between the pressingplates 193193* and the cross head1', which also forms a pressing-plate, and is again pressed. The material is then takenoff the chains by the roller-shaft s, and is drawn by the rollershaftst u n, in the order named, three times through the press between the pressing-plates p3 p3* and the cross-head fi', as shown by dotted lines, Fig. 2. The roller-shaft s has fixed upon its end a bevel-pinion s2, gearing with a bevel-pinion s3, xed on the shaft f8. By

e these means rotarymotion is imparted to the roller-shaft s. The rollershaft a is driven by the pinions2 through the medium of gearing u2 on the other side of the machine, as shown in Figs. l and 3b. The roller-shaft o is driven by means of a belt c', passingaround a pulley c2, fixed on the said roller-shaft and around a pulley c3, fixed on the'shaftf12. The said roller-shaft@ imparts rotary motion to the roller-shaft f by means of `pinions c4, only one of which is shown in Fig. l, the other pinion being directly beneath it. The roller-shaft i; is shown as made larger in diameterthan the shafts s, if, and u, so as to obtain a greater surface-contact for better drawing off the cloth. Between the plates 193193? and the plate t' the material is pressed between highly-glazed pa- .while itis in the machine.

The material then passes with the chains B around the wheels C C on the shaft fl2 and The materia-1 is then passed around the chainwheels G, near the feeding end of the machine, and is carried while on the part of the chains marked B2; again between the plates p p* and p2 19%, It is thenf passed around the chain-wlieels C C on the shaft f, and is carried while on that part of V per, or between metal plates or other suitable material, to finishand'set it.

Instead of direct-ing a currentor blast of hotair upon the surface of the `material 1n the manner ordinarily practiced, we provide means wherebyheated air can be passed between the folds of the cloth or other material `For this purpose we prefer to employ the perforated pipes D, from which the heated air will be ejected in 'a series of jets. These jets of air drive out the moist heated air and 'steanr that usually collect between the folds of the material, and also give a softness to the said material, aswell as drying the saine. To heat the air for this purpose, we prefer to utilize the exhaust-'steam from thecylinder c, and we usually effect this by conducting the said exhaust-steam through a receiver provided with tubes or passages through which the air to be heated is forced. This apparatus is shown in det-ail `in Figs. y9 and l0, andcomprises two chambers or casings G', located beneath the machine, as shown in Figs. 1 and 2, and each provided with a central pipe or tube I-l. The two pipes or tubesH are connected by the bent pipe l. The exhaust-steam f rom the cylinder is Vadmitted into the pipes H through the inlet-pipe J which is connected with the exhaust-pipe c2 of thecylinder c,'and the said steam escapes from the said pipes H throughl the outlet-pipe K. rlhe space between each pipe H and the walls of the corresponding chamber G is divided by partitions L into a series of passages M. The two chambers G are connected by a pipe N. The air to be heated is forced by means of a fan or blower (not shown in the drawings) into one of the chambers G through the pipe O and Hows throughithe passages M therein, thenn through the pipe N into the other chamber G, and through the passages M in this chamber, and leaves the said chamber by the pipe P. This air is heated by contact with the outer surfaces of the pipes H and with the surfaces of the partitions L, which are formed integrally with the said pipes. After bGUlg thus heated the air is forced through pipes Q connecting the pipe P with the perforated pipes D, and escapes between the folds of the cloth or other material being operated upon.

The operation of the press isv as follows? that is to say: When the press is in the position shown, the piston in the steam-cylinder c is at rest and the press open, and, as shown in Fig. 3, the tappet or bracket h is in its lowest position, so that the clutch is held in gear by the weight g3 acting upon the lever g. The

IOO

chains are therefore drawing a portion of the y cloth or other material being operated upon into position between the pressing-plates. The driving-pulley d and the gearing connected therewith arearranged to operate relatively to the drawing-in mechanism in such a manner that after each pressing operation is completed the material is passed through the machine a distance of, say, from eighteen inches to thirty-six inches, but never greater than the width of the pressing-plates. The cam'l), acting upon the lever d, admitz, steam into the cylinder c, the cross-head, table or plate 'L' rises, the tappet or bracket h throws the clutch out of gear by'means of the lever g and stops the drawing-in mechanism until the pressing is performed, then the cross-head t' descends, when the tappet 7i leaves the incline g2, and the Weight g3 again puts the clutch in gear for the purpose of bringing a fresh portion of the cloth into position to be pressed.

The stopping and starting of the machine are effected as follows that is to say: If the attendant, who'V stands at the feedingY end thereof, desires to stop the machine, he moves the lever or arm E so as to shift` the strap or belt onto the loose pulley a3 by means of the fork E. The lever E at the same time acts through the rock-shaft e2, arm E2, and rod E3 upon the lever F, and thus lifts the Weight g3, thereby releasing-the lever g so that the spring Q7 throws the clutch out of gear, and the drawing-in mechanism c'omes to rest.

It has been customary heretofore to` employ hydraulic pressure in machines of the v class abovedescribed, and the pre'ssure employed has generally been very considerable, sometimes amounting to two' hundred and fifty tous. XVe have ascertained that quite as good or better results can be' obtained by our improvements by employing a slight pressure. WVe therefore use a steam cylinder and piston instead of hydraulic machinery.

We claimy 1. The combination, with an endless chain for holding and moving the cloth by the lists or selvages, and tenterin g the same, of a series of vertically-movable heated plates,

one above the other, placed in the line' of travel of the cloth, and a steam cylinder, piston, and cross-head beneath said plates, and adapted to force them to'gethenwhereby the cloth While being tente'red will be pressed and finished between the plates, substantially l as described.

2. The combination of the cloth-stretchii'ig devices, means for adjusting the same, expansible and contractible pressingplates, and means whereby they will be expanded or contracted simultaneously with the adjustment of the cloth-stretchin g devices, substantially as set forth.

3. The combination, with the steam press'- in'g-cylinder c, provided with an admissionvalve, a cam, a power-shaft connected with said cam for operating the same, a lever connecting the said cam with the admissionvalve, the pulleys a a3, the piston-rod c', the cross-head t', the pressing-plates, the chains,
