MILLING AND FULLlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 537,170, dated April 9, 1895.

Application filed September 22, 1894. Serial No. 523,827- (No model.) Patented in Belgium May 26, 1894:, No. 83,960, and in Austria July 3,1894, No. 2,900.

To all whom it may concern:

Be it known that we, SAM PRESTON and BEN PRESTON, subjects of the Queen of Great 2,900,) of which the following is a specificatlon.

This invention relates to machinery or apparatus employed for milling and fullingi woolen, woven, felted, or other fabrics, and it has special reference to that class of machines for which Letters Patent were granted in the United States of America to William D. Bald win, administrator of the late Benjamin Preston, the fifth day of June, A. D. 1894, No. 521,126, in which the two operations of milling and fulling are performed simultaneously in the same machine by arranging the falling stock feet to work vertically at the end of the milling machine. The object of the present invention is to construct a combined milling and falling ma-v chine with an adj ustable bottom, a turn made in two or more pieces capable of being raised or lowered to or from the said adjustable bottom, said machine being provided with 0 without flangeless milling rollers.

In the drawings: Figure 1 is a longitudinal section of a combined milling and fulling machine embodying ourimprovements; Fig.2,a transverse section on line 00 m Fig. 1; Fig. 3, an external side elevation of machine.

A is the framework of the machine, which is made of metal in the usual skeleton form and provided with an inner lining of wood, earthenware, porcelain, or the like, or two or more of these materials combined; but alining A of wood is more generally employed. The framework A and lining A constitute the casing of the machine.

At Fig. lin order to avoid complicating the drawings, we have omitted to show the skeleton metal framework A in dotted lines behind the lining A. The framework A and its lining are provided with a top or covering A of the usual construction and material. B B are the fulling stock feet, stepped as shown, and arranged to work, at the'rear of the milling portion of the machine, in suitable slides and between the width contracting pieces A A of the lining A. The stock feet B B receive a vertical reciprocating motion from the shaft G of the machine through cranks 0 C connecting rods 0 O and blocks 0 O fixed as shownto the stock feet.

D D are the milling rollers which may be flangeless (or not) as shown and they are arranged at a suitable distance from the stock feet B B within the framework of the machine, and mounted on shafts supported by pedestals or adjustable bearings arranged to be fixed on or work in the said framework. The rollers are built up in parts, that is to say, two flanges d d'are provided of any suitable size and thickness. On one or both of the said flanges d (1', maybe cast or fixed a boss d and a ring 01. Aboss is shown on each flange in the drawings. Around the boss and between the said flanges are placed, and bolted thereto, any desired number of wood segments d preferably four, or six, made the endway of the grain. These segments are of such a thickness as to suit the diameter of the rollers, and, the flanges d d may or may not project beyond the periphery of the wood laggings or center portion of the roller. They may also when required be lined or edged with a ring d* of brass, earthenware or its equivalent to prevent them or the rollers wearing away at the edges.

Composite milling rollers D D constructed as herein described and shown may be held together by bolts 01 passing through the flanges cl d and secured to the shaft by keys d. 'They may also be used in place of the rollers now employed on milling machines of ordinary construction. When the flanges do not project beyond the periphery of the rollers the sides of the spout or trough E may be made to extend to or beyond the center of the rollers up to, or nearly to, the throat F and the sides and bottom of the spout E may when desired be provided with an inner lining of wood, brass, earthenware, porcelain or equivalent material which may extend the whole or any portion of the length of the spout. The requisite tension to the rollers D D maybe imparted thereto by flat springs 'Fig. 0.

D one end of which is connected to stationary rod or fixing D while to the opposite end is jointed a rack D which engages with a pinion D actuated by worm and wheel D through shaft D and hand wheel D The rollers D D are geared together with suitable spur or other gearing D and motion is imparted to them through driving pulley D".

E is the spout of the machine through which the material operated upon, after passing between the milling rollers D D, passes to the fulling stock feet B B. The spoutE may be made to taper and may be provided with a lid E jointed to the shaft of the upper milling roller D as shown and it is weighted at E to give the requisite drag to the material passing through the spout. G is the knocking off board connected by levers in the ordinary manner with the belt slipping mechanism. H is the turn or adjustable bed, which is mounted within the framework of the machine the contracting pieces A A being at any suitable distance below the rear end of the spout of the machine.

The turn or adjustable bed may be mounted upon a bar H carried in adjustable bearings I'l on the framework of the machine whereby the distance between the turn and stock feet B B may be increased or diminished as required. The bearings Il are carried on the ledges a of framework A and secured thereto by bolts 0. arranged to slide in slot holes (L The position of each bearing H may be adjusted by a screw a as shown at The turn or adjustable bed Il may be made in one or more pieces of any suitable shape and length so as to extend to any required distance from under the spout to the bottom lining of the machine.

In the drawings a turn or adjustable bed is shown made in three pieces H, H H The piece I1 is fixed at an angle to the piece H, while the piece H is jointed to the piece H so that its front end It may be raised or lowered by the chain H whenever the latter is wound or unwound on the pulley H mounted on shaft H, which is rotated by worm and worm wheel I'l through shaft H armed with a hand wheel 11*. In orderto keep the lower piece 11 to'its work it is weighted at H as shown. The angle of the turn or adjustable bed may also be regulated by means of a bar I jointed to the piece I1 and provided with any desired number of holes by which it may be pinned to the cross-piece Ifixed to the lining A of the machine.

J is a curved false bottom jointed atj to the end A of the machine and it works between the contracting pieces A A The false bottom J is capable of being raised or lowered by hand by any convenient means, such as an eccentric J actuated by hand wheel J and gearing J whenever the exit orifice II is required to be contracted or enlarged.

K K are the ordinary rollers for guiding the fabric.

L is a fly wheel mounted on the end of the crank shaft.

M M are pulleys around which the belt M passes for transmitting motion to the crank shaft 0 and stock feet from the milling roller shaft.

By constructing the machine as herein described, there is less danger of the fabric being damaged while at the same time the combined milling and fulling operations are performed in less time and with better results.

In some cases when preferred, we arrange within the machine, say in any convenient position in front of the mouth of the turn or adjustable bed H and below and beyond the milling rollers D D one, two, or more rollers N N for spreading or opening out the cloth or other fabric as it leaves the stock feet. Any or the whole of these rollers may be armed with spiral blades or pins 91 arranged round the periphery or peripheries of the rollers so as to run in the same or opposite directions. These rollers may be driven by the drag of the material operated upon, or by gearing or its equivalent.

Having now described the nature of our invention, what we claim, and desire to secure by Letters Patent, is-

1. The combination, substantially as hereinbefore set forth, of a casing having a con tracted portion, milling rolls contained within the casing, mechanism for operating the milling rolls, means for imparting the requisite drag upon the material, reciprocating stock feet contained within the contracted portion of the casing, mechanism for operating them and an adjustable weighted bed interposed between the milling rolls and stock feet and co-operating with the stock feet, said bed being made in pieces jointed togetherand means for raising and lowering the weighted end of the said bed.

2. The combination of the casing havinga contracted portion the milling rolls the reciprocating stock feet contained within the contracted portion of the casing of the machine the adjustable weighted bed interposed be tween the milling rolls and stock feet and cooperating with the stock feet, said bed being made in pieces jointed together and means for moving the upper end of said bed to and from the stock feet and means for raising and lowering the weighted end of said bed.

3. The combination of the casing the milling rolls, the reciprocating stock feet con tained within the casing of the machine the adjustable weighted bed made up in pieces jointed together capable of being moved to and from the stock feet at one end and raised and lowered to its work at the other end, means for raising and lowering the weighted end of the said bed, the false bottom hinged within the casing of the machine below the stock feet, and means for raising and lowering the free end of the false bottom to and {roam the weighted end of the said adjustable co-operating with the weighted end of the adjustable bed and the spreading out rollers in terposed between the milling rolls, the adj ustable bed, and the guide roller.
