SPECIFICATION forming part of Letters Patent No. 376,993, dated January 24 1888. .Applicntion filed May 7, 1887. Serial No. 237,404. (No modal.) Patented in France January 15, 1880, 'No. B4542:

To all whom it may conaerm' Be it known that I, CLAUDE T oHoN, acitizen of the Republic of France, residing at Chan lieu, Department of Loire, France,. have invented certain new and useful Improvements in Machines forFinishing and PolishingTextile Fabrics, (for which I obtaineda patent in France, No. 134,542, dated January 15, 1880,) of which the following is aspecification. [C The object of, this invention is to provide a means for finishing and polishing textile fabrics ina more perfect manner than has heretofore been done. I

My improved finishing and polishing machine involves a rubbing action on the surface of the fabricwhereby the weft and warp threads are smoothed down and spread out uniformly and all irregularities removed therefrom, thus condensing the surface of the goods and closing the interstices withoutinjury thereto.

The essential features of a machine adapted toperform this work are: an elastic or yieldingbed upon whichthe goods are held; means.

5 for rubbing all parts of the exposedsurface of the goods uniformly, preferably composed of a series of rotating flexible blades; feeding mechanism andmeans for drawing the goods over the bed and applying tension in all directions thereto to prevent creasing during the action of the blades thereon. In submitting some classes ofgoodsto this process it is desirable that the rubbing action should take place transversely on the goods- -that is, in 3 5 the direction of the weft. In other goods the rubbing is preferably applied longitudinallyi or in direction with the warp; and in some goods it may be desirable to apply the finishing and polishing operations in both directions thereon, for. which reasons I make two distinct machines, .one' having the flexibleblades arranged to actt-ransversely and the other having the flexible blades arranged to act longitudinally on'the goods.

The longitudinal finishing and polishing machine forms the subject of another application for Letters Patent .filedv simultaneously herewith under'Serial No. 237,405. The transverse finishing and polishing machine is here- 4 5o inafter fully described and shown inthe accompanying drawings, to which I will refer, and in which-- Y Figure 1, Sheet 1, is a front elevation thereof.

The. mainframe a is rectangular in form, and in the upper part thereof is located the. box I), which holds the elastic bed and which is supported on thelevelingscrews b b; The

elastic bed is composed of the india ruhber air-chamber a, secured to theedgesofthe box. b,a cloth covering, 01, preferably made'of mole-skin,-extending.over the whole upper surface of the airchamber c, and strips of. leather 6 6, located under the polishing de- 7 vice. (See Fig. 6.) The strips of leather-cc are drawn taut bymeans of lacings at'their ends. (See Fig. 3.) p Y Air is'l'orced into the elastic bed, through the pipe-c, fromany suitable source-as, for'in- 8o stance, an air-pump,-c, which may be operated by manual or other powerand the clasticity' of the bed is regulated by the manipu- I lation of the cock' 0. Across the machine, just above the elastic bed, are placed the gird 8 em a a, on which are" secured the bearings for the shafts f f. These shafts have secured to their ends the gear-wheels f f, meshing,

into one another and driven by the pinion'f v fastened on a short shaft provided with the 0 pulleys f iand carried in a bracket at the end 1 of the frame a. K

From the bearings of the shaftsffproject the studs 9 g, alternately arranged on either side thereof and on which are fitted to rotate 9 By referring to Fig. 2 it will beobserv'edQr-co Fig. .7, Sheet 4:, is aplan 1 that the arrangement of the polishing devices hhin the rows or different series on either side f of the shaftsff is such that all parts of thegoodsj, as they are drawn under the polishing devices, are uniformly acted on by them. The

direction of rotation of each of the polishing devices It is indicated by an arrow.

The enlarged views, Figs. 7 and 8, more clearly show the construction of these polishing devices, which consist of flat blades h h, of spring-tempered steel,'re-enforced by side springs h 712-, and held in positions oblique to their axes in recesses formed in the hubs t 2" by means of screws passing through them and wedge-shaped pieces i 4". By using clamping-pieces i i" of more or less obliquity the angular positions of the blades h h may be varied at pleasure to cause them to act properly on different goods. The object of arranging these blades so that the whole of their edges do not strike the goods at once is to remove any creases from or tendency to crease of the goods; and it will be observed that where adjacent polishing devices move in opposite directions on the goods their blades are inclined in opposite'directions, so that the dragging action of one of the blades is opposed by that of the other, and where adjacent polishing devices move in the same direction on the goods grippers are placed between them to press the goods firmly onto the elastic bed during the polishing action of the blades thereon.

To hold the polishing devices on the studs g 9, one end of each of the levers k, which are pivoted on the girders a, passes behind the back of each of the miter-wheels i, and they are held in thisposition by means of the springcatches k acting on their other'ends. These holding devices permit ready removal of the polishing devices for adjustment, &c.

All of the polishing devices are set so that their blades act on the goods together.

In the main views of the drawings the blades and the grippers have just left the goods to allow them to be fed forward without obstruc tion. These grippers consist of bars extending from the ends of bell-crank levers Z l, pivoted to the girders a a. They are arranged to hold the goods on the bed so that the dragging action of the polishing devices shall be opposed similarly by them-that is, they are made right and left and are marked, respectively, land Z. They are actuated by studs projecting from the bars at and m and fitting into slots formed in the vertical arms of the bell-cranks. These pairs of bars at and m slide in bearings above the shafts f f, and are at one end of the machine connected together by short levers m, by means of which a reciprocating motion applied to one of them is imparted to the other with reversal of direction. The bars at actuate the grippers l and the bars m the grippers Z. The bars mare joined at their other ends to the bar m which is provided with pins or rollers at its ends arranged to work in the cams n and a, one of which is secured to the shaft of the drivingpinionf, at the rear end of the train of gears and the other one to the shaft of the pinion at the front end of the train of gears. These cams n and n work in unison, so as to move the bars at uniformly together, and they are so set as to cause all the grippers Z Z to grip the goods just before the blades of the polishing devices act thereon and to raise them therefrom after the blades leave the goods.

The goods to be treated are placed on the roller 0 at the rear of the machine. They pass over the guide-bar p, the elastic bed, and the guide-roller q, and are wound up on the roller 1" at the front of the machine. This roller 0 is actuated intermittently to free the goods, when free of the polishing blades and grippers, by means of the pawl 1', carried on the end ofthe lever r", so as to work in the ratchetwheel r", secured to the shaft of the roller 1-. ris a retention-pawl. The other arm of the lever w is slotted and provided with a sliding block forming a part of or connected to the nut s, fitted to slide in the slotted arm of the bellcrank levers, which is pivoted at s to the frame a. The upper end of the vertical arm of the bell-crank lever s is connected by the rod 1. to the crank t, carried on thcshaft of the pinion u, which meshes into one of the wheels of the train ofgearsf. This crankt makesa full revolution for each action of the blades of the polishing devices hon the goods. The length of goods fed forward by each revolution of the crank t is determined by the position of the nut s in the slotted arm of the bellcrank lever s, which is set by the manipulation of the screw 8, having bearings in the slotted arm and passing through the nut 8. (See Fig. 3.)

To insure that the goods are fed forward and held during the finishing and polishing operation without irregularities or creases, a peculiar form is given to the guide bar p and the guide-roller q, viz: They are both higher at their central parts 1) and qthan at their ends, thereby imparting to the goods while being drawn over them a tendency to move laterally from the center to both sides. The end 2 of the bar 1) is higher than the corresponding end q of the roller q,and the other end,p", of the bar is lower than the other end, q, of the roller, as shown in the perspective view, Fig. 5. Thus a slightly-retarding action is imparted to one edge of the goods as they approach the elastic bed and a similar action imparted to the other edge of the goods as they leave the bed,which opposing actions, somewhat of a twisting natur'e, combined with the spreading action due to the high central parts of the guide-bar p and roller g, cause the goods to lie perfectly flat on the elastic bed. This is very essential for the proper finishing and polishing of the goods by means of edge rubbers acting thereon to smooth down and spread out the threads in an efficient and uniform manner.

The combination of the devices here described, while performing all the functions for which it is designed, acts so gently on the erases v I goods that all knots and excessive irregularities are eliminated, as far asappearance goes, without breaking or' otherwise injuring the weft and warp of the goods. i

The cloth covering d over the air-chamber o constitutes a soft yielding surface, and the strips of leather e 6 form a durable smooth surface for the polishing-blades to press the goods against, and theyare capable of being submitted to sufficientstrain under tension to prevent excessive raising of the air-chamber at the central part of the bed.

Having now described the nature of my invention and ascertained the manner in which it is operated, What I claim, and desire to secure by Letters Patent, is''- v 1.
