ToaZZ whom it may concern.-

Be it known that I, MAXIM LA FOUNTAIN, J r., of Springfield, in the county of lVindsor and State of Vermont, have invented certain new and useful Improvements in Adjusting Means for Instrumentalities in Cloth-Finishing Machines, of which the following is a specification.

This invention has reference to machines for finishing cloth, such as gigging and napping and shearing machines; and it has for its object the provision of improvements in means for adjusting certain of the instrumentalities in machines of the character mentioned, so-as to meet particular requirements or necessities, and to effect such adjustments by a single movement from one side or at one point of the machine.

To these ends my invention consists of a hand-wheel and its shaft combined with the element, part, or device to be adjusted and its movable supports or bearings on opposite sides of the machine, adjusting devices so arranged in connection with the said supports as that they may move the same in order to secure their adjustment, and means intermediate of the said hand-wheel shaft and said adjusting devices on both sides of the machine, whereby the adjusting devices may be operated simultaneously and to the same extent or degree by the operation of the said hand-wheel, all as I will proceed to describe more in detail hereinafter and then point out with particularity in the appended claims.

Reference is to be had to the annexed drawings,formin'g a part of this specification, and to the letters marked thereon, the same letters designating the same parts or features, as the case may be, wherever they occur.

Of the drawings, Figure 1 is a side view of a combined teaseling, gigging, and shearing machine to which my improvements are applicable. Fig. 2 is a detail side view of one form of my improvements, showing it applied in such a way as to operate a wire brush to effect the cleaning or clearing of teasels from all flock or wool that happens to become lodged upon them. Fig. 3 is a rear view of the same, parts being shown as in section and other parts as broken out or broken away. Fig. at is an end view showing my improvements as applied in such manner as to adjust the cloth-guiding rolls in a gigging-machine for the purpose of letting the cloth on or off the gigging rolls or workers, so that the latter may operate with greater or less energy on the cloth, as the same may consist of light or heavy goods, or as circumstances may require. Fig. 5 is a rear view, a part being represented as broken out, showing the invention as adapted to be applied to a shearing-machine for the adjustment of the shearing devices proper, so as to effect a more or less close shearing of the nap. Fig. 6 is a sectional side or end view of what is represented in Fig. 5, and, in addition, parts immediately coacting withthe same. Figs. 7 and 8 are detail views of parts comprised in the construction shown in Figs. 5 and 6. Fig. 9 is a vie w somewhat similar to Fig. 6, but showinga slightly-modified construction. Figs. 10 and 11 are detail views of parts comprised in the construction shown in Fig. 9.

In the drawings, a designates the frame or supporting means for the moving parts of the machine, and A designates the teaseling part, B the napping part, and O the shearing part, of a cloth-finishing machine in which these functions are performed. (See Fig. 1.)

Referring to part A of said machine and to what is represented in Figs. 2 and 3, b is the teaseling cylinder or drum, provided with teasels (not shown) in the usual way. As is well known, the teasels, after being in use for a time, become clogged with flock and wool or other substance, so as to be rendered ineificient until they are cleaned or freed from such clogging substance. Heretofore it has been common in order to clean the teasels to take them off the cylinder and clean them with a hand-card or with a bristle brush. This method was not only inconvenient, but consumed much time, and hence was done at considerable expense. In the application of my invention to-t-his part of the machine this expense and loss of time are avoided, since I am enabled to efiect a cleaning of the teasels without removal from the cylinder in less than one minute of time. This is effected by the following instrumentalities operating in combination:

0 is a cylindrical wire brushthat is, a brush composed of wires extending radially from the periphery of the cylinder. The said brush is journaled in boxes cl, supported by the upper ends of brackets e, which are adapted to slide vertically in guideways formed in the uprights f, supported on theframe a.

through the medium of the said hand-wheel the sliding bracket, and consequently the brush, may be raised or lowered. When the brush is raised, it will be brought into contact with the teasels on the teaseling-cylinder, and when lowered it will be removed from contact therewith. To make the brush effective by way of clearing the teasels when brought into contact therewith, it must be rotated, and when the said brush is out of contact with the teaseling-cylinder it is desirable that it should be quiescent. These ends are attained through the means next to be described. 7

71 is a pulley fixed on one end of thebrushshaft, around which pulley and a pulley l, turning on the short shaft m, secured to the frame, there passes a belt 72-. Oompounded with or secured to the pulley Z is a pulley 0, driven by a belt 1) from a pulley on any suitable moving shaft of the machine. \Vhen the brush is in lowered position, as is shown in the drawings, though the pulley Z will be driven the belt or will not be operated, but when the said brush is raised the belt will be tightened on the pulley l and the brush will be rapidly rotated, so that when itis brought into contact with the teasels it will quickly and thoroughly clean or free them from all clogging substances. \Vhen the hand-wheel is released by which the brush is raised, said brush will be lowered by its own gravity to the position shown in the drawings and its rotation will cease. The wire brush is an important feature of this part of my invention.

Another partor application of my invention is illustrated inFig. 4 in connection with what is portrayed at B in Fig. 1. In these figures the invention is shown as employed to let the cloth in a gigging-machine on and off the napping-rolls by the adjustment of the guide-rolls.

In the instance atpresent under consideration, (1 designates a hand-wheel whose shaft ,1" is provided with a worm s, which engages and is adapted to turn a worm-gear t, compounded or connected with which is a pinion n, which meshes with a gear or segment 1*, provided with an arm 10, in the end of which is journaled one end of a cloth-guiding roll :20. Under these conditions when the hand-wheel q is turned the segment r ,may be likewise turned and so move the cloth-guiding roll no nearer to or farther away from the nappingrolls y, causing the cloth .2, passing thereover and guided thereby, to bear with greater or less force on the napping-rolls, with the result of securing greater or less napping energy in the operation of the last-mentioned instrumentalities.

Compounded with the worm-gear tand pinion n and turning upon the same shaft is a sprocket-wheel a, about which and four similar sprocket-wheels a is passed a sprocketchain b, so that the said four additional sprocket-wheels are turned in unison with and to the same extent as the sprocket-wheel first described. Oompounded with each additional sprocket-wheel a is a pinion a, similar to the pinion n, which engages a toothed gear 7;, provided with an arm to, which carries one end of a cloth-guiding roll 00. Each toothed gear or segment o engages a similar gear or segment 11, provided with an arm w, likewise having one end of aclotlnguiding roller a: journaled therein. It will now be seen that as each additional sprocketwheel is moved it will operate the cloth-guiding rolls journaled in the arms 10 and to through the medium of the gearing described, so as to let the cloth on or off the nappingrolls, or, in other words, so as to cause the cloth to bear with greater or less force on the napping-rolls.

It will be understood that the shaft to which the worm -wheel 25 is secured may extend through the machine, so that the cloth-guiding rolls may be operated and controlled by means similar to those just described and in exact unison therewith, all movements being accomplished by the one operation of turning the hand-wheel q.

011 the face of the worm-wheel i there is inscribed a suitable scale 0, which, in connection Withthe fixed pointer or hand cl, indicates with exactness the degree of adjustment of the cloth-guiding rolls toward or from the napping-rolls and affords a means of adjusting the said cloth-guiding rolls with certainty to suit different grades or weights of goods. great saving of time is also efiected by being able to make the adjustments from a single point in the machine and by the movementledger-blade and shear by means of a screw on each side of the machine, the operator turning the said screw to effect the adjustment on one side of the machine, and then going over to the opposite side'and performing the same operation. Those skilled in the art will understand that this method not only consumed much time, but was uncertain in its effects. By the use of my improved means I can secure the desired adjustment from a single point and by the movement of a single elementor instrument and with certainty of getting the same degree of ad j ustment on both sides.

In the figures now under consideration, 6 designates a hand-wheel on the shaft f, on which is a worm g, which engages a wormgear h, on whose shaft h is fixed an eccentric i, which operates in a surrounding strap j, forming part of a hollow interiorly-screwthreaded stud k. Tapped into the stud k is a screw Z, on which the frame m, carrying the ledger-blade n and rotary shear 0, rests. The frame m is pivoted at 19, so that as the free end of the said frame is raised or lowered the ledger-blade and rotary shear will be carried farther away from or be brought nearer to the rest q, over which the cloth 2 travels, and so effect a longer or closer shear of the nap on the cloth. A check-nut 0" holds the screw Z in adjusted position in the stud k.

It will now be seen and clearly understood that the adjustment of the ledger-blade and shear may be effected by the simple operation of the hand-wheel c, it being kept in mind that the shaft h extends across the machine and is equipped with similar cooperating means on the opposite side, as is clearly indicated in Fig. 5. Any other equivalent means may be employed in lieu of the shaft h for effecting the adjustment of the frame-supporting screw Z on the side of the machine opposite to that shown in Fig. 0. The worm g also engages a worm-wheel s, which, through the medium of bevel-wheels if and it, turns a shaft or arbor :0, on which is fixed a pointer or hand g, which, in connection with a scale .2 on a fixed dial a, indicates with exactness the extent and direction of adjustment of the shearing devices.

In Figs. 9 to 11, inclusive, a slightly-modified form of means is shown for effecting the adjustment of the frame m. In this instance the stud or support It for the screw Z is not internally screw-threaded, but the worm-gear h is, and the latter engages the said screw Z, which is kept from turning in its stud or support is by means of a pin 12, operating in a slot 0 of the said stud or support 7o. By this means the turning of the Worm-gear it moves the frame-supporting screw up or down, as the case may be. I attach great importance in this part of my invention to the fact that the adjusting means on both sides of the machine are so connected that by the operation of a single hand-wheel or its the movable bearings, pinions for moving the racks, a hand-wheel for operating the said pinions, a pulley on the shaft of the rotary wire brush, and a belt connecting the two pulleys, the belt being of such length that when the brush is moved to engage the teasels, the brush will be rotated, and will be quiescent when it is away from the teaselingcylinder.
