MACHINE FOR DRESSING HOOPS.

SPECIFICATION forming partof Letters :Patent No. 281,737, dated July 24, 1883, Application filed April 17l 1883. (No model.)

To all whom it may concern:

Be it known that I, NATHAN PAGE STEVENS,

of Concord, in the county of Merrimack, of

the State of New Hampshire, have invented a new and useful Improvement in Machinery for Dressing Hoops 5 and I do hereby declare the sam e to be described in the following specifi cation, and represented in the accompanying drawings, of which Figure 1 is a top view; Fig. 2, a side elevation 5 Fig. 3, a longitudinal section, and Fig. fl, a transverse section of a machine embodying my invention, the nature of it being defined in the claims hereinafter presented. The I5 said transverse section is taken through the axis of the cutter-cylinder, the longitudinal section being taken in a plane going through the middle of one set of the yielding and adj ustable hoop eveners or rollers. rlhe machine 2o as represented has two sets of such eveners, each set of them being composed of three rollers, two of which are parallel to each other and at a distance apart and above the third one, each being not directly over but aside of 2 5 or at a distance horizontally from such third one, as represented. Fig. 5 is a vertical section of the frame G, and two eveners and their carriers applied thereto, as hereinafter explained. Gis a rear end elevation 5 and 3o Fig. 7, another or side elevation ofthe machine. i A

The important novel feature of the machine, by which it difters from other machines for dressing hoops by means of feed-rollers, a cutter-cylinder, and drawing-rolls, is in what I term the eveners, 7 each set of which, as represented, `consists of three rollers, each of which is not only provided with a spring or like means to enable it to yield or move up and 4o down vertically, but has mechanism to admit `of its adjustment nearer to or farther from the cutter-cylinder, as occasion or the thickness of the hoop to be dressed may require. These eveners are arranged between the feed-rollers 4 5 and the cutter-cylinders, as represented in the drawings, in whichA is the said cuttercylinder; B, its throat-plate; C and D, the pair of feed-rollers5 and E and F and E and F, two sets of drawing-rollers.

This machine is a duplex one, inasmuch as it is capable of dressing two hoops at one and the same time. It has two sets of eveners, a single cutter-cylinder, one lower feed-roller, two upper feedsrollers, and one lower draw` ing-roller to each set of drawing-rollers, and besides it has a single throat-piece to the cutter-cylinder. Each upper feed-roller, aswell as each upper drawing-roller, is a yielding onethat is its carrier is supported by a spring or springs to enable the roller to move upward 6o and downward relatively to the fellow roller underneath it, whose only movement is that of revolution on its own axis. All the uppermost of the rollers are connected with a frame,

G, which at one end is hinged to the frame R for supporting the cutter-cylinder and the lower feed and drawing rollers.

In Fig. 3 the three eveners of one set are shown at H, I, and K in their relative positions. Each upper evener has its journals 7o supported in a furcated carrier, c, whose shank b is provided with a shoulder, c, and extends upward through a supporter, L, and is screw-threaded at its upper end, as shown at d to receive a nut, c, which screws on the 7 5 screw d, and against the upper end of a sleeve or tubular screw, f, which is arranged concentricall y on the shank I), and is screwed down into the supporter L and against the upper end of a spiral spring, y, encompassing the 8o shank l and resting on the shoulder c. The supporter L rests at its middle on the median. bar, 7L, of the frame G, and is connected thereto by one ormore clamp-screws, z', each of which goes down througha slot, 7c, made transversely 8 5 inthe supporter, and screws into the said bar, the same being so as to admit of the supporter being moved in order to adjust the evener nearer to or farther from the cutter-cylinder,

as occasion may require. The machine shown, 9o being a duplex one, as described, has two evenersto each of the supporters L, though in a single machinel adapted to dress but one hoop at one time there would be but one evener to each of the supporters, which would be ad- 9 5 justable, as described, on the frame. Each lower evener, K, has its journals supported in a furcated carrier, a', whose shank b is provided with a shoulder, c', and extends down through -an adjustable supporter, L', sustained Ico .2 2eme? tude of the evener can be varied, as the thickness of the hoop-pole to be dressed may require.

Each upper feed-roller, as well as eachl upper drawing-roller, is supported by means, such as described, for sustaining an upper evener and allowing it to yield vertically, such upper feed or drawing roller being` what is usually termed a pressure-roller, it operating to keep the hoop down upon the fellow roller beneath such feed or drawing roller. The two drawing-rollers have gears Z u on their shafts, which engage with an intermediate gear, m, and there is a pulley, o, fixed on the shaft of the roller F. An endless belt, p, goes around the pulley o, and a pulley, p, at one end of a shaft, q, arranged as shown. At the other end of the said shaft is another and larger pulley, r, about which and a pulley, s, on the shaft of the cutter-cylinder an endless belt, t, passes, such shaft having a drivingpulley, u, at one and each end of it. About another pulley, fu, on the cutter-cylinder shaft, and alarger pulley, w, on another shaft, w, an endless belt, y, travels. Another endless belt, z, goes around a pulley, on the shaft a", and also around a pulley, b2, on the shaft of the lower feed-roller, D.

On the cutter-cylinder being put in revolution the lower feed and drawing rollers will, also be revolved; and 011 a hoop being introduced between the feed-rollers C D it, by the lower of them, will be impelled forward upon the evener K and between it and the eveners H and I, and thence will be caused to pass to and over the cutter-cylinder A and its throatpiece B, and thence between the rollers of each set of the drawing-rollers E F and E F', it being in the meantime planed or dressed on its lower or flat or sawed surface by the cutter-cylinder. rlhe evener K and both of 'the eveners H I, or the evener I only, arranged as shown, with the evener K, support and guide the hoop to much better advantage than would two rollers only arranged one directly over the other, the upper of them only o r each of them being a yielding roller, because with the three eveners, or with the eveners I and K arranged as represented, when a knob yor projection of the hoop may be passing an upper e of the eveners the hoop-pole can spring down independently of the roller K, which serves then to hold it up to the upper evener or eveners, and with such directs the hoop properly to the cutter-cylinder. The having each upper evener disposed above and not directly over the evener K, but at a sufficient distance horizontally therefrom, substantially as represented, renders the machine productive of better results in evenly dressing the hoop than would be the case were it to have a set of eveners wherein one would be directly over the other.

In some cases the evener I-I may be dispensed with, the evener I, arranged above the evener K and between it and the cutter-cylinder, being used.

It is customary sometimes to saw a hooppole twice diametrically, so as to separate it into four strips, each of which is quadrantal in transverse section. Each strip has subsequently to be reduced, so as to make it segmental in cross-section. To properly guide such strips to the feed-rollers of the machine I use rollers M, freely revoluble on a sustaining-shaft N, each roller having in and around it at its circumference a groove triangular in cross-section, the said supporting-shaft being 'vertically adjustable in the machine.

l. The combination of the feed-rollers O and D and the cutter-cylinder A with the evener K, and yalso with the evener I, arranged above 'the said evener K andvcutter-cylinder and between them, such eveners being between the feed-rollers and the cutter-cylinders and to operate substantially as set forth.
