MACHINE FOR PRESSING FABRICS.

SPECIFICATION formingpart of Letters Patent No. 352,253, dated November 9, 1886..

` Application filed January 6, 18H5. Serial No. 152,175. (No model.)

To all whom t may concern.-

Be it known that I," GEORGE W. MILLER, a citizen of the UnitedyStatesand a resident 0f Woonsocket, Providence county, `Rhode Island, have invented certain new and useful Improvements in Machines for Pressing Fabrics, of which the following is a speciiication.

My invention relates to that class of machines in which fabrics are pressed between revolving cylinders and beds arranged adjacent to said cylinders; and my invention consists in means,- fully set forth hereinafter, for regulating the pressure upon the fabric, for removing it therefrom, for directing one or more fabrics to the cylinder, and for `pressing continuously Without friction or ironing.

In the drawings, Figure 1 is a perspective View of `a pressing-machine illustrating my improvements.- Fig. 2 is a sectional elevation. Fig. 3 is adetached View illustrating the, arrangement of the cylinder, beds, and press- Fig. l is a view illustrating the arrangement of the carryingbands.`

The side frames, A, of the machine are i suitably connected and constructed to support the operating parts herinafter described.

Between the frames is secured the lower presser-bed, B, having a concave upper surface adapted to the cylinder C, the shaft d of Vwhich cylinder turns in bearings d', adapted to vertical guides in the frame.`

To each side frame is connected by a link, j', a lever, D, in the outer end of which lever turns a shaft, g, that passes through slots x in vertical rods U, and which is provided with a handle, g', and. carries eccentrics P, bearing upon friction-'rolls b b on the rods U. Thel lower end of each rod U is connected to a lever, R, pivoted at one end, carrying a Weight, W, and extending at theopposite end over a rod or bearing, y, as in the device'patented to me September 18, 1883, No.v 285,052. Each leverD is provided with two side ears or Wings, 5, extending below the lower edge, and with vertical slots, and each bearing d', is provided .with an ear, `6, at the top, which ear fits hetween the ears 5, and carries aA pin, e, which Y enters the slots in the ears 5, forming a loose connection between the levers and bearings, which vpermits a limited play of the'levers in dependently of the bearings.

Thevupper pressure-bed, B, has a curved the ears 6, so as to elevate the levers D until the pins. e are at the lower ends of the slots-A in the ears 5, to then prevent any movement of the levers independently of the bearings d', and the upper pressure-bed is held away `from the cylinder while the lower bed only is used, and no goods are pressed by the upper bed. On the end of the shaft disatoothed Vwheel, W, which gears with a pinion, X',`

upon a shaft, X. y r

By the arrangement of parts above described I am enabled to relieve the fabric rst of the pressure of the weight W, then to separate the. upper bed from the cylinder, and then lift the cylinder, with the upper bed, to separate the cylinder from the lower bed, and also to lift the wheelW from itsv connection with the driving-pinion X. This is effected by a single movement of the shaft g. Thus the parts being in the position shown in Fig. 3, and the shaft g being turned in the, direction of its arrow, the rod U will first descend until the levers B take their bearings on the rod y, when the weight Wwill no longer act to depress the levers D, and the cylinder will be relieved of the pressure of this weight. The continued movement of the shaft g will then lift the 1evers D and carry the upper bed away from the cylinder, so that there can be no pressure on thefabric between them. When the pins e are inthe lower ends of the slots 5 in thelevers, the bearings d and the cylinder will be lifted from the lower bed, the fabric being thus -relieved from pressure upon both sides ofthe cylinder. As the rotation of the shaft g elevates first the levers D and then bearings d and shaft d, the' wheel W is raised with the bearings from vits connection with the pinion X', when the rotation of the cylinder will be arrested.

Rolls F G G2 H lIz are supported to turn in suitable bearings inthe frame of the machine, and a carrying band or apron, F2, passes around the roll F and around the cylinder, another band, H, passes around the upper bed ICO and around rolls H' H2, and between tlie lower bed and the cylinder passes a band, G, which extends around the rolls G and G2. rIlhis permits the fabric to be passed between the bands H F2 upon the upper side of the cylinder, and then between the bands F2 G upon the lower side of the cylinder, so as to receive two pressures, or it permits two fabrics to be pressed at once, one, Y, Fig. 4, being carried from a bundle, p2, over tension-bars downward and between the band F", Fig. 4, and the band H, andthe other,Y2, being carried from the bundle p' between the band F2 and the band G, upon the oppositeside of the cylinder, but in a contrary direction. In eases where the face of the fabric is to be planished it may be carried in direct contact with the polished face of the bed and cylinder instead of between two of the bands.

At each side of the cylinder C, but in different planes, is located a stretcher-cylinder, I, and adjacent to each stretcher-cylinder is a steamer, V, the said cylinders and Steamers being of any ordinary or well-known construction.

Upon shafts turning in bearings upon the front end of the machine are carried suitable brushes, J J', the brush-shafts being driven by abelt, J4, which passes around guide-pulleys J5 J, and` around a pulley upon the driving-shaft X2, so that the brushes are rotated in opposite directions. A tension-roll, K, is supported at the upper front portion of the frame above a guide bar or roll, K', and a guide bar or, roll, K2, is arranged at the rear of the brush J. Some fabrics require brushing on one side only, and some upon both, and the amount of brushing required varies with the character of the goods.

In order to properly conduct and operate upon the fabric,-I employ, in connection with the brushing and guiding rolls, suitable regulating or guide bars, L L', hung between arms m upon shafts N N', supported in bearings in the frame, and each shaft carrying at one end aslotted plate, I2, through the slot of which a bolt, I', passes into the frame to serve as a means of securing the shaft in place after its adjustment, a handle, Q3, serving as a ready means of rocking the shaft. The fabric is carried from the bundle or file P' over roller K',

past the under side of brush J, between the' lower guide-bar, L, and the brush J', directly upward past brush J', to the roller K2, and over the upper brush, J, and then under the upper guide-bar, L', and over and around the tension-roll K.

The extent to which the fabric is submitted to the action of the brushes J J' will depend upon the position of the guide-bars L L' in respect to the brushes, the fabric being folded to a greater extent around the periphery of the brushes in proportion as the guide-bars are brought nearer to the latter. In like manner the position of the adjustable guide-bar L3 in respect to each stretching-roll I determines the extent to which the fabric is presented to the said roll, and the adjustment of the fabric thereby varies the extent of the action of the roll thereon.

It will be seen that by the means above described the path of the fabric can be easily controlled, so as to bring it in contact upon both sides with the brushes to a greater or less extent, and so as to vary the amount of surihce subjected to the action of the stretching-rolls.

It will of course be understood4 that the various operating parts are connected by suitable gears or belts, so as to be operated in unison from the single driving-shaft.

The guide-bars L L' L3, instead of being earried by arms upon a rock-shaft, maybe adjustable in slots in the side frames of the machine, so as to permit them to be moved in respect to the brushes or rollers; or any other known equivalent means of securing said adjustment maybe employed, and any suitable known and equivalent clamping appliances may be used for securing the said bars after they are adjusted.

The levers D may have link or other known equivalent connections with the upper bed, B', which will permit a limited movement of the levers in respect to the said bed.

In an application filed by me May 19, 1884, and numbered 131,970, I have shown and claimed a press with a stationary bed and revolving cylinder, and bands passing between the same and carried and guided by rollers; hence I do not claim such constructions in this application.

Withoutlimiting myself to the precise construction and arrangement of parts shown and described, Iclaim- 1. The combination, with the cylinder and upper and lower beds and cylinder-bearings, of levers D, having loose connections with the bearings of the cylinder, and arranged to lift the upper bed when elevated, and the weighted levers R, rods U, movable connections between the rods and levers D, and stops y, all substantially as set forth.
