SPECIFICATION forming part of Letters Patent N 0. 674,229, dated May 14, 1901.

Application filed March 21, 1900. Serial No. 9,538. (No model.)

To ctZZ whom it may concern.-

Be it known that 1, JOHN E. WINDLE, of North Grafton, county of W orcester, State of Massachusetts, have invented an Improvement in Cloth-Doubling. Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention in cloth-doubling machines has for its object to support in a novel manner the cloth being led to the doubling devices.

In my invention I apply the cloth to be doubled upon a carriage movable outside the framework and transversely to the longitudinal axes of the feeding-rolls which take the cloth from the doubling device preparatory to winding the same. The carriage is herein represented as movable upon a track secured to the outside of the frame and also upon a suitable track located at the floor, and the carriage has suitable guiding-rollers about which the cloth is passed on its way to the doubling devices. By mounting the carriage outside the framework, as stated, the operator may readily lay the goods to be doubled upon said carriage, thus obviating the difficulty of reaching under the framework to deposit on the carriage the goods to be folded, as in United States Patent N 0. 523,499, and by reason of this carriage, mounted as described, it is possible to more readily adjust the position of the cloth with relation to the doubling apparatus,-so that the cloth may be doubled exactly in its center and yet provide that the strain exerted upon the cloth be in the proper lines; otherwise the cloth cannot be handled and doubled uniformly. The rollers in the traveling carriage are made adjustable that they may be alined correctly one with the other to insure passage of the material to be folded in a straight line.

Figure 1 of the drawings represents a righthand side elevation of a doubling-machine embodying my invention, and Fig. 2 is a view of the machine shown in Fig. 1 looking at it from the left-hand end.

Referring to the drawings, A represents the upright or side frames of the machine, secured in usual manner to the floor. The framework A has suitable stands erected thereon to constitute supports for the holders a a, connected, respectively, with shafts provided with toothed gears a and a The gears of and a are engaged by like pinions a and a fast on the main shaft-ct of the machine, said shaft having applied to it (see Fig. l) a suitable clutch-pulley a adapted to receive a suitable belt driven from any usual counter-shaft to rotate the shaft a when it is desired to wind the doubled cloth or other material.

. It will be obvious that the invention herein described is applicable to doubling not only cloth, but any textile or web-like material.

To the framework, at one side thereof, I have secured by bolts 1) a stand I), having an extended ear b upon which istmounted a bar 0, which corresponds with a bar designated by like letter in my Patent No. 523,499, dated July 24:, 1894, said bar having cooperating with it suitable rods 0, which converge at the free end of the bar a and constitute a truncated former, the bar bracing the former and'holding it firmly in position while the material being doubled is being drawn over the former and wound upon the winding board C, common to my said patent.

The framework sustains suitable pressurerolls B, through which the doubled cloth is drawn by the act of winding the same on the winding-board, or it may be a roll, and the cloth between the former and the pressurerolls is passed between suitable smoothingrods (1, also common to my said patent.

Herein the framework is provided with suitable short tracks 2, which receive upon them suitable wheels 3, represented as grooved at their peripheries, said wheels being mounted on studs extended backwardly froma suitable traveling carriage D, of a length nearly equal to the length of the side frame A of the machine, (see Fig. 1,) said carriage having at its lower end a platform (1, having suitable rollers 61 to run on tracks (1 located on the floor, said carriage also having other suitable rollers (1 which contact with the, sides of the frame, so that said carriage is free to be slid longitudinally of the length of the frame and at right angles to the longitudinal axes of the rollers B B and also of the cloth-winding mech-.

anism.

The carriage D has fast upon it, as herein represented at its front edge, a suitable smoothing-board e, against which passes one side of the material 6 to be doubled. The board at its front side near its upper end has attached to it by suitable screws 6 suit-able stands a and to the upper ends of each of said stands is fixed by a set-screwet a bearing 5,having ears provided with adjusting devices 6, which act upon and adjust bearings 7, which receive (see Fig. l) the journals 8, extended from a guide-roll e. To restrain the rotation of this guide-roll, so that more or less force may be required to turn it, thus causing it to act as a friction-roll to detain the cloth more or less as the latter is being drawn through the machine, I provide the bearing 10 at the right-hand side of the machine, Fig. 1, with a plate 12, and I interpose between the end of the roller 6 and said plate a friction-washer 13,which may be of any suitable material, and I have provided a device by which to force the right-hand end of the roll 0 against said washer to thereby determine the extent of friction, said device consisting, as herein shown, of a thumb-screw 14L, (see left of Fig. 1,) the threaded shank of which enters a threaded hole in the bearing 7 and contacts with the end of the journal 8, entering said bearing.

Each stand 0 has connected with it by suitable screwsfsuitable boxesf, which receive the ends of a rodf under which the cloth taken from a pile of cloth laid on the platform (1 of the carriage passes on its way to and over the guide-roll 6 said cloth leaving said guide-roll and passing behind the board e of the traveling carriage and thence passing over a tension device G, composed of a shaft g, having its ends mounted in suitable bearings g in suitable standsfixed to the carriage D, said shaft having at one end-the left-hand end of Fig. 1-outside its bearing a locking device g shown as a plate, having suitable notches or shoulders g and thereafter said shaft has connected with ita handwheel gflsaid hand-wheel being mostly broken away in Fig. 2 to show the locking-plate behind it and the locking-dog g which cooperates with said locking-plate to hold said tension device in its operative position. The tension device is further composed of arms 9 fixed to the shaft 9 and extended backwardly, as represented in Fig. 2, said arms carrying a second rod g The tension device is shown in its operative position in the drawings; but by lifting the notched end of the lockingdog g and engaging the hand-wheel and turning it in the direction of the arrow near it in Fig. 2 the bar g may be swung under the shaft g to the right, thus completely removing the tension device from contact with the cloth. By a change of position of the rod g withrelation to the shaft g the cloth may be made to contact with more or less of the surface of the shaft g and the rod g and thereby increase the tension on the cloth. The cloth after passing the tension device is carried over the side of and under the guide-roll 7t and thence to the left viewing Fig. 2 up over the former, the two selvages of the cloth being retained in the dotted line w at the right in Fig. 2, the fold of the cloth being represented by the dotted line 10', the cloth passing from the former between the rods (1 and between the rollers Band being connected in the usual manner to the winding board or roller. The roll it has its journals mounted in suitable adjustable boxes h, changeable as to their position by or through suitable screws 7L2, and the journal at one end of said roller has applied to it a suitable pulley h grooved at its periphery and embraced by a friction device It, shown as two concaved bars held yieldingly together by means of a spring h, surrounding a screw it, (see Fig. 2,) one of said concaved bars (see Fig. 2) being divided in two parts, one part being pivoted at 72/7 on the other part, the freely-movable part of the bar having a device, which may be turned in one direction when it is desired to entirely release the friction from the roll it and in the other direction when it is desired to exert friction upon the said roll.

One of the shafts supporting one of the wheels 3 has a hand-wheel m, which may be turned to rotate the wheel connected with it and cause the carriage to be moved in one or the other direction upon the tracks 2 and (Z so that the cloth to be folded, whatever its width, said cloth having been properly applied to the rollers c andh, as described, may be so placed by the adjustment of the position of the carriage as to locate the center of the width of the cloth to be doubled at exactly the proper position with relation to the position occupied by the former, its position being fixed, it will be remembered, with relation to the framewerk.

If the cloth should fail to run evenly, the adj usting-screws 6 and 20, controlling, respectively, the bearings of the rollers e and It, may be adjusted so that the strain upon the cloth may be exactly determined to insure a straight-line movement of the selvages of the cloth to be doubled.

Prior to my invention I am not aware that cloth or any material to be doubled has been sustained upon a carriage movable on a track outside the framework of the machine and transversely of the longitudinal axis of the winding material for the doubled cloth, and therefore I desire to claim this invention broadly, irrespective of the particular construction shown of the carriage or of the bearing-rolls mounted in the carriage.
