MACHINE FOR NAPPING CLOTH.

SPECIFICATION forming part of Letters Patent No. 484,700, dated October 18, 1892.

Application filed February 1, 1892. Serial No. 419,917. (No model.)

To all whom it may concern:

. Be it known that we, GEORGE W. BURR- and MICHAEL MALoNY, both of Webster, in the county of Worcester and State of Massachusetts, have invented a new and Improved Ma'- chine for Napping Cloth, of which the following is a full, clear, and exact description.

Our invention relates to improvements in machines for finishing or raising the nap on woolen or worsted goods, and is especially intended to be used in connection with the ordinary shearing-machine.

The object of our invention is to produce a simple attachment for a shearing-machine havingoppositely-rotatingnapping-cylinders,

with their needles arranged so as to raise the nap of the cloth both ways at the same time, and also to produce a tension device by means of which the pressure of the cloth upon the cylinders may be easily and accurately regulated.

Our invention further consists in the peculiar construction of the cylinder-needles; and with the above ends in view it consists in certain features of construction and combinations of parts, as will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure l is a front elevation of the machine provided with our improved attachment. Fig. 2 is a vertical longitudinal section of the same on the line 2 2 in Fig. 1. Fig. 3 is a broken side elevation showing our improved attachment. Fig. 4 is an enlarged detail sectional view of one of the napping-cylinders with a portion of the exterior surface removed. Fig. 5 is a broken plan view of one of the nappingcylinders with the needles removed, and Fig. 6 is a detail view of a modified mechanism for driving the cylinders.

The machine has the usual frame 10, like the ordinary shear and gigging machine, and beneath the main portion of the frame is the customary form of curved bed 11, having a shelf 11 at one end. On the top of the frame are brackets 12, which support the common form of rotary shearing-cylinder 13, and opposite the shear are the rests or guide-bars 14,

over which the cloth runs and which serve to hold the cloth against the shearing-cylinder. The machine has, also, the usual brush 15, arranged centrally and transversely therein and mounted on the shaft 16, which has pulley 17 at one end and is driven by a suitable driving-belt 18.

The above construction is common to machines of this class and forms no part of our invention. At the opposite end of the shaft 16 is a pulley 19, which connects by means of a belt 20 with a pulley on a shaft 21, which shaft extends transversely across one end of the machine, as shown in Figs. 1 and 2, and carries the upper napping cylinder 22. There are two napping- cylinders 22 and 23, placed one above the other, and these are of exactly similar construction and are held to turn in opposite directions. Eachcylindercomprises a core 24, a backing 25 for the cylinder-needles, which backing is composed of suitable firm material and is wrapped spirally about the core, the yielding substance 26 in the form of a fabric, which is wrapped exteriorly and spirally upon the backing 25, and the needles 27, which are held in the material 26 and the inner ends of which rest upon the backing 25.

The needles 27 are features of our invention and are of common carding-wire, but are bent back slightly at the point where they leave the material 26, and the ends of them are ground forwardthat is, in the direction in which the cylinder rotatesso as to produce short sharp hooks, as shown in Fig. 4, which hooks serve to raise the nap of the cloth. The napping-cylinders are geared together at one end, being connected by the gear-wheels 28, which causes them to rotate in opposite directions, the said short sharp hooks of both cylinders projecting in the direction of rotation thereof, thus raising a nap both ways on the cloth. The napping-cylinders may, however, be driven by any suitable mechanism, and another form of driving mechanism is shown in Fig. 6, where the upper cylinder is provided with a pulley 29, the lowerone with a pulley 29, and a pair of pulleys 30 are mounted in a bracket 31, their shafts being held to slide in the slots 32 in the bracket and being secured in place by suitable nuts 324. The pulleys 30 are arranged below the napping-cylinders, and a continuous belt 33 runs over the pulleys 29, and 29 and beneath the pulleys 30.

The machine has at the end opposite the napping-cylinders the usual guide-roller 34, with the small guide-bars 35 at each side thereof, a guide-roller 36 near the upper end of the machine and above the guide-roller 34, the guide-roller 37, arranged near the top of the machine and between the shearing-cylinders 13 and the brush 15, so as to hold the cloth to the brush, guide-rollers 38, arranged parallel with each other and beneath the brush 15, so as to enable the cloth to properly pass the brush, a guideroller 39 in advance of the rollers 38 and a little above the same, a guide. roller 40, arranged beneath the lower cylinder 23, and a tension-roller 41, arranged be tween the planes of the cylinders 22 and 23 and a little in advance of them, this roller forming part of our invention.

A guide-roller 42 is mounted above the upper cylinder, a guide-roller 43 on the top of the frame and in the rear of the roller 42, a guide-roller 44 in advance of and a little below the roller 43, a guide-roller 45 above and in advance of the roller 44, and the usual swinging guide-frame 46. These guide-rollers are arranged substantially as in the ordinary machines of this class and form no part of our invention; but the tension-roller 4.1 is an important feature of the invention, as by it the pressure of cloth upon the nappingcylinders may be nicely adjusted. This roller 41 has its ends journaled in rack-bars 47, which bars are held to slide horizontally in keepers 48, secured on the inner sides of the main frame, and the inner ends of the rackbars engage pinions 49 on a transverse shaft 50, which shaft is journaled in suitable supports on the main frame and carries at one end a bevel gear-wheel 51, which meshes with a bevel-pinion 52 on the end of a shaft 53, the latter being mounted in keepers 54 and extending longitudinally along one side of the machine, the shaft terminating at one end in a hand-wheel 55, by means of which it may be turned, and by turning the shaft 53 the shaft maybe also turned, so as to cause the pinions 49 to act on the rack-bars 47 and 50 either advance or retract the tension-roller 41, so as to regulate exactly the pressure of cloth on the napping-cylinders.

The cloth 56 is fed to the shearing-cylinder 13 in the usual way, and from thence passes downward over the roller 37, beneath the brush 15, being operated on by the brush, thence beneath the parallel guide-rollers 38, over the guide-roller 39, beneath the guideroller 40, thence upward in front of the napping-cylinders and in contact with the tensionroller 41, thence in front of the roller 42, up

over the roller 43, beneath the roller 44, and

over the roller 45 to the shelf 11 of the bed 11.

ping-cylinders having needles inclined in a direction opposite to their direction of rotation and terminating in burrs or points ground on the ends thereof and projecting at an angle therefrom in the direction of rotation of said cylinders, of mechanism for rotating the cylinders in opposite directions, and suitable guides for holding the fabric in proper relation to said cylinders to be acted upon by said burrs or points, substantially as set forth.
