SPECIFICALION forming part of Letters Patent No. 315,809, April 14, 1885.
Application filed January 30, 1884. (No model.)
To all whom it may concern.-
Be it known that I, ANDREW hiCLEAN, of the city, county, and State of New York, have invented a new and Improved Tentering-Ma chine, of which the following is a full, ciear,and exact description.
My invention consists in the construction and combination of parts, as will he hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a plan view of my improved tentering'machine shown applied to a dryingmachine, a part only of the drying-machine being shown. Fig. 2 is a side elevation of the same. Fig. 3 is a front elevation of the tentering-machine. Fig. 4 is mainly a sectional ele vation taken in the line a: m of Fig. 2, showing the construction of the guide-roller, some of the parts, however, being shown in elevation. Fig. 5 is a sectional elevation of the guideroller, taken on the liney y of Fig. i. Fig. 6 is an end elevation of one of the feeding and stretching wheels and its head-pieces support removed from the machine. Fig. 7 is asection of the same, taken on the line z z of Fig. 6, parts being shown in elevation. Fig. 8 is a side elevation of one of the segment-plates composing the outer circumference of the preferred form of feeding and stretching wheel, and Fig. 9 is a front elevation showing a modification of the power-transmitting mechanism used with solid feeding and stretching wheels.
M is the frame of the machine, in which are journaled the plain rollers A B G, guide-roller D, plain front roller, E, and regulating-roller F, all arranged in the same horizontal plane, as shown in Figs. 1 and 2. On each side of the regulating-roller F a stretchingwheel, G, is placed, which stretching wheels are arranged obliquely to the said regulating-roller. Mot-ion is communicated to the rollers E F and stretching-wheels G G,in the construction shown in Figs. 1 to S, from the shaft D of the roller D. The said rollers A, B, G, D,E-, and F, and feeding and stretching wheels G G, to-
gether with said shaft D and shafts H, I, J, K, and L, (employed in revolving the regulatingroller F and feeding and stretching wheels G from said shaft D,) are all journaled in or supported by the frame M, made a part of or situated in front of the ordinary drying-machine, which latter consists, in this instance, of the large steam-heated cylinders or drums M, (three being showm) which are adapted to be revolved by suitable power, (notshowin) and which in this instance, through gears m m,secured to the drums or asles thereof, and the pinions rub, a, (l, and a, secured, respectively, upon the gudgeons or shafts of the rollers A, B, C, D, and E, impart motion directly or indirectly to all of the operative part-s of the tentering-niachine.
The pinions a, b, 0, (Z, and e are differentially made that is, the pinion or having a less nu mber of teeth than I), and the pinion b a less number of teeth than c, and so on throughout the series-so that the rollers A, B, C, D, and D have differential motion, the roller A hav ing the greatest speed, which differential motion causesthe rollers to exert a stretching ac tion upon the web of cloth when passing through the machine in the direction of the length of the web, providing the rollers selected should be all of the same circumference; but different circumferential sizes of rollers may be used, and as their surface is the controlling inlluence in stretching the cloth the gears may be arranged so as to suit the circumferences of the rollers that may be used, but so that there shall be a gain of surface motion to each roller as the cloth advances over them to the drying-machine or other apparatus.
The guide-roller D is a skeleton roller composed of the slats d, secured at their ends to the edges of the circular headplates d" (i secured upon the shaft- D of the said roller, as shown clearly in Figs. 1 and i, and surrounding the roller D are the sliding guide rings or rims D which are for the selvages of cloth to run on when desired. The slats (l are cut away at their edges to form the slots dflthrough which the radial arms h of the guide-rings D" pass, and in which the said arms move when the said guide rings or rims D are slid to or from each other to suit the width of the cloth. The guide rings or rims D are by preference cast integral with the said radial arms 71- and Lil tions, with a shaft, f,
' ing the selvages of the cloth at withthe centralsleeves, h, which latter fitloosely upon the shaft D, sothey may slide easily, and the rings or rims in this instance are adapted to be slid simultaneously to and from each other by the shaft D, by means of the right and left hand screw-threads h it cut thereon, with which the guide rings or rims D are connected by the nuts k h and curved yokes h h, which latter fit in the circumferential grooves k if, made in the guide-rims D as will. be understood from Figs. 4 and 5.
The regulating-roller F is made in four secpassing lengthwise through its center, to which the sections and its pinion k are affixed, and the shaft f is journaled in the supports f f, bolted upon the bar N, as shown, or the shaft f may be supported in any equivalent manner. The roller F receives motion from shaft K through pinion it placed thereon meshing with. pinion it placed upon shaft L, which latter pinion meshes with the pinion k affixed to the shaft f of the said regulating-roller F.
The two feeding and stretching wheels G Gare arranged at the ends of the regulating-roller F, and; are independent thereof, and are-for feedthe required speed, and also for stretching the goods to the requisite width, and for this latter purpose.
are placed at angles or obliquely in the machine, and are each provided with the pinpoints g, to which the selvage edges of the cloth are first fed by the attendants. The wheels G .G are duplicates of are held .upon the bar N by the gndgeonblocks 0 O and head-pieces Q Q, and are adapted to be slid to and from each other upon said bar N to suit the width of the cloth.
\ The said wheels G G are also adapted to be chine, to increase or diminish adjusted vertically and also with reference to their degree of angle or obliquity in the matheir stretching action on the width of cloth, and in one form they are made sectional and adapted to be expanded and contracted circumferentially,
so as to feed more or less selvages of cloth, at
. each revolution tosecure an even parallel or square movement of the opposite selvages of the cloth through the machine, while in another form they are made solid or non.-expansive, in which lattercase each side is provided with cone-pulleys, as in Fig. 9, to vary speed of either side,
The bar N, which is supported upon the bracketN and beveled at its edges, is the main support of the head-pieces Q Q and stretchingwheels G G and the gudgeon-blooks 0 O, which latter are dovetailed upon the bar N, and constitute the intermediate support for the said wheels, and these blocks 0, 0 are screw-tapped with right and left hand screwthre'ads to receive the similar screw-threads out upon the shaft 1?, which is adapted to be easily turned by applying the hand toany part of the screw-rod or to a hand-wheel each other, and 1 as required, to feed the, selvages square and even and at proper speed.
fixed thereon for moving the wheels G G simultaneously to or from each other,
Q Q, Figs. 6 and 7, are the headpiecesjournaled upon the vertical gndgeons 0, projecting upward from the gudgeon-blocks O O, and to the ends of these head-pieces Q Q are secured, by the bolts 9' j, (seeFigs. 2, 3, 6, 7, and 9,) the journal-plates ER, in which the wheels G G, through the medium of the trunnions i and spindle to be presently described, take their bearings, and these journal-plates R R are made vertically adjustable by means of the slotsi 2' made therein, through which the bolts j j pass, so that by loosening the said bolts j the wheels G G may be raised or lowered, as required, and the head-pieces Q Qare each provided with one or more set-.
screws, Z, which act against the upright gndgeons of the blocksO 0, so that by loosening these set-screws the wheels G G may be turned or swung to any angle desired, or as circumstances require, and there held by turning up the said set-screws Z.
As above mentioned, the feeding and stretch ing wheels G G may be made solid or non-ex pansive, or in sections, and so as to be adapted to be expanded or contracted circumferentially. The latter form of wheels are by preference each constructed, as shown in Figs. 6, 7, and 8, of the inner cone-shaped hollow suitably grooved for arms k to slide in, surrounding segmental plates 9 I annular back plate, 9", screwed to the cone-shaped hollow casting g for holding arms k and segmental plates g inplace, and large coiled or circumferential spring 9 for holding the segmental plates 9 in place by passing the spring over the knob k on each segment, thus forming a circular coil of spring pressing each segment toward the center of thewheel, as hereinafter Lil casting,g
described, and as will be understood from Fig.
7.v Thesegmcntal plates are each formed asshown in Fig. Sand described below. The hollow cone-shaped casting g is formed at the base with the radial -slots or ways i, and at the smaller or apex end with the hollow trunnion i'flwhich runs in one of the journal-plates Rand in the hollow trunnion t is fixed the spindlej,
' which runs in the other journal-plate R, and
this spindlej has placed upon it i j and adj usting-nut 1' for the purposes herein- 4 after described. The segment-plates g in this instance have a serrated or ribbed crown three-fourths inch wide, and are each stepped with three steps one-fourth inch wide and 'onefourth inch deep, the bottom step-being onehalfinch wide, which constitute four diameters on which to feed the selvages of cloth at more or less speed, and may have less or more steps, and are each provided upon the outer, curved surface with the above-mentioned pin-points g, placed about one-fourth inch apart circumferentially, or more or less steps be provided with pin-points g. The crown of the plate (shown in Fig. 8) is formed with the serrations or ribs it to be used instead of the pinthe cone-nut points 9 for we g e cloth upon the serrated or rihtued suriare as occasion may require. The segment-plates are also formed or provided with the arms k" and the former being adapted to fit in the radial slots or ways 2" ofthc coneshaped casting g, the latter to have the above-mentioned coiled spring 9 placed over the knobs k secured to said arms for holding the segmental plates g in their proper places and for drawing them inward, so that the inner beveled ends of the arms is will restin contact with the beveled end of the conenut j. The armsk" are of course all ofa size and length, so that the outer surfaces of the plates g, when all of them are in place and held by the spring 9 constitute a perfect circle. The cone-nut j is in this instance feathered upon an enlarged portion of the spindle f, as shown in Fig. 7, and is adapted to slide upon the said spindle, and the said nut is chambered and internally screw-threaded at its rear or larger end, as shown at i, to receive the externally-screwthreaded portion fofthe abovementioned adjusting-nut j", so that by turning this nutj to the right or left the cone-nut j will be accordingly forced inward or drawn out-ward. If forced inward toward the cavity of the cone-shaped casting 9", the conical end of the nut j will act equally upon all of the beveled ends of the arms and force all of the segmental plates 9 outward equally, thus enlarging or expanding the circumference of the wheel G. Upon withdrawing the coneshaped nut j the segmental plates 9" will all be drawn inward by the action of the spring g as the nut j recedes, thus contracting the circumference of the said wheel G, the effect of which is that as it is enlarged or contracted a greater or less amount of selvage of cloth is fed as maybe required at each revolution.
To prevent all danger of the adjusting-nuts turning of their own accord from the jar of the machine or otherwise, I form upon the outer surfaces of the cone shaped nuts j the notches c, and provide the nuts j with the spring-friction pawls e", which run in contact with the outer surfaces of the cone-shaped nuts and engage with the notches e therein with sufficient force to retain the nuts, but not so but that the nuts 3' may be readily turned by hand for quickly expanding or contracting the stretching-wheels G without stopping the machine, and I place the collars in upon the spindles j", as shown clearly in Figs. 1, 3, and 7, for holding the coneshaped nntj and adjusting-nut j properly in place upon their spindles, the latter nut being free to rotate on said spindle.
The sectional feeding and stretching wheels G G are both revolved indirectly from the drying-rollers, as described, and directly from the same shaft I, Fig. 3, by the endless chains S S, which pass over the sprocket-wheels p p and 1) p secured, respectively, upon the spindles j and the said shaft I.
As above stated, the tenteringmachine is inginachine.
not in this instance driven by a separate inotive power, but is driven from the gear at of the drying-machine, and in the arrangement shown the guide-roller D or the shaft D thereof is the drive roller or shaft of the tenter- These being revolved through the train of gearing connecting them with the large gear in upon the first drying cylinder or drum M,impart motion to shaft H through the endless chain H,which passes over sprockct-whccls q and g, secured, respectively, upon shafts H and D. The shaft H imparts motion to the shaft J through belt T and cone-pulleys s and s, secured, respectively, upon the said shafts, and the shaft J imparts motion to the shaft 1, through the endless chain I, which passes over the sprocket-wheels t t, secured, respectively, upon the shafts I and J, and the shaft 1 in turn,throngh the said endless chains S S and sprocket-wheels p p and p 1;,imparts motion to the feeding and stretching wheels G G, as just stated; and the shaft H also drives the shaft K by the belt K, which passes over the cone-pulleys w and '10, and the shaft K, as above stated, imparts motion to intermediate gear, it, and regulating-roller F through the gear-wheels or pinions 7:, 7t, and 70 The solid or non-expanding feeding and stretching wheels G G are also stepped with three steps, more or less, and provided with the pinpoints g on one or more steps, as shown in Fig. 9, and may or may not be serrated or ribbed on their crowns. \Vhen these solid or non-expanding wheels are used, they are not both revolved from the same shaft,as the sectional-wheels in Fig. 3 are, but are revolved, as shown in Fig. 9, by separate mechanism, consisting, in this instance, in addition to the shaft H, (which is the same in both Figs. 3 and 9,) and the other n'iechauisrn described for transmitting motion thereto from shaft D, of the two upper short shafts, U U, Fig. 9, which are revolved from shaft H by belts V V passing over cone-pulleys a u and u it,secured, respectively, upon said shafts H and U, and the two lower shafts, U U,which are revolved from the upper short shafts, U U, by the endless chains \V \V, which pass over suitable sprocket-wheels a a, secured upon said upper and lower shafts, as shown in said Fig. 9. The two feeding and stretching wheels G G are revolved by the endless chains S S passing over suitable sproclcetwheels, p p,secured to the shafts of said wheels G G, and over sprocket wheels p 11, secured upon said shafts U U, while the regulatingroller F receives its motion from shaft K, as described, the same as in Fig. 8. By shifting either of the belts V V upon the eone-pulleys u a the speed of revolution of either of the feeding and stretching wheels G G may be increased or diminished, as desired, for regulating the speed of feeding the selvages of cloth as required.
It will be seen from the foregoing that the speed of the stretching-wheels may be regu- The operation of the machine is as follows:
The cloth to be run through the machine is placed in a box or other suitable receptacle, or
maybe previously wound on rollers and placed near the floor under wheels G, Fig. 2, at a suitable distance from the machine, so that the cloth will, in its course up to the feeding and stretching wheels G, be on a convenient slant tosuit the attendants. The cloth to be stretched and dried will be started in this instance in the machine by means of a cord attached to the cloth and passed first over the regulating-roller F, then under the roller E, then over the guide-roller D, then under the roller 0, and so on over and under alternate rollers throughout the tentering-machine, and also over and-under alternate drying cylinders or drums M throughout the drying-machine, the goods being thus properly placed in the machine. Some fabrics of cloth, owing to their texture, &c., in passing through the tentering-machine have a tendency to run slack at their selvages after leaving wheels G G and while passing under and over rollers E and D. In such cases the guide rims or rings D of'the guide-roller D will be slid to suit the width of the cloth, or so as that a strip of selvage one to three-quarters of an inch in width on each side of cloth passes on the sloping portion of rim or rings D; but if the fabric is such that there will be no tendency of.
the selvage edges to run slack, then in this case the guide rims or rings D are slid apart, so that they will be clear of the passage of the cloth altogether, which sliding of rims or rings D is done by turning the shaft D by the crank or hand wheel upon'one end of the shaft D The feeding and stretching wheels G G are also slid to or from each other by turning the shaftP to bring them nearly up to the proper width of the cloth, and they are set to a greater or less angle with each other, or with the center line of the machine, according to the amount of sidewise stretch it may be desired to give the cloth,this adjustment being effected by turning the head-pieces Q Q upon the gudgeons of blocks 0 0. This done, the machine will be set in motion by starting the motive power (not shown.) attached to one of the drying cylinders or drums M, which will revolve the same and draw the cloth along through the tentering-machine, and also through the drying-machine. There will be an attendant stationed at each wheel G G, and as the cloth enters the tentering-machine over the roller F the attendants will place the selvage edges.
farthest apart or to the side of the wheels opposite to where the cloth is fed, so that owing to the angular or oblique arrangement of the wheels G G they will exert a powerful stretching action upon the width of the goods, while the differential movement of the surfaces of the rollers of the tentering-machi-ne, as above stated, exerts a powerful stretching action upon the cloth in the direction of its length as it passes from roller to roller, so that the cloth in passing through the tentering-machine is properly stretched in all directions.
WVhcn in operation, it is often found that one edge of the cloth enters the tentering-machine more rapidly than or gets ahead of the other. In this case if the sectional stretching"- wheels are used the attendant will apply his hand to'the adjusting-nutj at the side of the machine where the goods move too fast, and turn it so as to withdraw the cone-nut jflwhich will contract the size of the stretching-wheel G at that side of the machine, and thus feed a less quantity of selvage and straighten or square the goods-so they will feed even in the machine. If the solid or non-expansive feed and stretching wheels are used, he will shift one of the belts V to the right or left upon the cone-pulleys u u by belt-guides (not shown) to increase or diminish the speed of one of the solid stretching-wheels G G, as required,and thus by retarding the edge of the goods which move too rapidly, or increasing the speed of the edge which moves too slowly, cause the selvages of the goods to enter the machine evenly.
The object of the crown and three steps with pin-points on the different steps of Wheels G G is that if the selvages from any cause get temporarily out ofsquare the attendant on the side that the selvage gets ahead may feed on either of' the lower steps of less diameter until the cloth gets square, when feeding will be resumed on the upper row of pin-points, while the attendant may, on the side that selvage gets behind, feed on the crown above the pin-points on the serrated or ribbed portion, which by its greater diameter will feed in more cloth until the cloth becomes square and even.
If it is found that the body of the cloth between the selvages moves too fast ortoo slow, which movement is governed by the friction of the cloth in contact with roller F, the attendant will shift the belt K to the right or left by belt-guides (not shown) upon the conepulleys w w to increase or diminish the'speed of the regulating-roller F. By thus decreas ing the motion of roller F if the body of cloth moves ahead of selvages, or increasing the motion of roller 1* if the body of cloth lags behind the selvages, the body of the cloth is so regulated that it shall run even and square across its width.
Vhcn it is desired to change from one width of cloth to another, the roller F may be lifted out of the machine, when wheels G G are slid to the required distance apart. Duplicates of roller F of different lengths to suit widths of cloth are provided, and when wheels G G are set to the required width a roller of the width required is set in place of the one'lifted out.
In case the pinpoints g are not used, or partly used, in the feeding and stretching wheels G, the attendant may feed the edges of the cloth upon the crown or circumferential serrations or teeth i which will in a measure retain the edges of the cloth, and thus cause the goods to be stretched in their width to a limited extent. In other cases the crown may be plain and the serrations or ribs may be dis pensed with, when less strain on the cloth edges will suit.
The pinion c is made movable upon the shaft of the roller 0, as shown in dotted lines in Fig. 1, so that when shifted out of engagement with the pinions d d the main operative parts of the tentering-machine will not be revolved by positive power, but by the frictional contact with the rollers of the wet or starched cloth being drawn through the machine by the cylinders of the drying-machine, which will exerta more or less powerful lengthwise stretching action upon the cloth, as may be desired, than when positive motion is used.
