FEATHER-CRIJSl-IING MACHINE.

SPECIFICATION forming part of Letters Patent No. 274,936, dated April 3, 1888.

Application filed December 6, 1882. (No model.) I

LII

To all whom it may concern Beit known that I, WILLIAM HAMMERMIL- LER, of Ghicago,.in the county of Cook and State of Illinois, have invented certain new and useful Improvements iifFeatber-Orushing Ma chines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accorn pan ying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has for its object to produce a machine that will crush the quills and shafts of coarse feathers to make them suitable for bedding; and it consists of the novel devices and combinations of devices, hereinafter debars a, that are serrated on their projecting edge in a manner that each formsa row of V-shaped teeth. These bars a, I secure rigidly in their respective grooves by shrinking an iron ring, I), over each end of the cylinder A andbars a. This cylinder A is mounted upon a shaft, B, that turns in solid bearings c, and has a pulley, 0, upon its overhanging end.

D is a semi-cylindrical shell, that has flanges d, for bolting it uponfthe wooden frame E.

, Against the ends of this shell D are bolted the flanges f of two rings, F, inside of which the bearings c of shaft B are adjustably held from four opposite sides, each by four set-screws, e. The cylinderA is eccentrically pivoted to the shell D ina manner that the open space be,

tween such shell D and cylinder A is wider on one side than on the other, and that such shell D forms the concave for the cylinder. A series of grooves are planed into the shell or concave'l), into which steel bars 9 are inserted,

that on their projecting edges are serratedto correspond with the serratures of bars a. The teeth of these bars a and g approach each other by degrees as the space between the cylinder A and concave D becomes less, and the serrated plate h, that is bolted upon the end of concave D, leaves but a very narrow clearance between the teeth of such bar hand of bars a. The barsg are siinilarlysecured in their respective grooves of concave I) by bolting an iron strap around each end in such concave that will cover the ends of plates g.

G is the feed-table, having side boards, 1'; and H, the cap, that is placed upon the concave, and provides the feed-openingj, and has the partition K, that divides the feed-inlet fromthe dischargespace. In one end of this cap 11 isan oval opening, I, to which the blast-pipe L of fan M is connected, while the opposite side of the cap is entirely open to communicate with a room or chamber intowhich the feathers are discharged by the force of the air-blast after passing through the machine. Both the crushing-cylinder and fan are driven by bolts from a shaft, N, and pulleys O and P. The coarser kind of feathers, that on account of their hard and inelastic quills and shafts would Otherwise be useless for bedding, are placed upon the feedtable G and are pushed into the openingj, where the roller A, that is driven with great velocity, will carry such feathers into the space between the roller and concave, when the teeth of bars a and g, as they approach each other and the clearingspace becomes less, will crush and break such feathers in a manner that after the feathers have passed the teeth of plate h the quill and shaft of each feather have become soft and pliable, aud yet retain a sufficient elasticity to make them well suitable for bedding.

I do not wish to be restricted to the particu- V-shaped teeth around such cylinder on spiral lines.

The above machine will not flatten the quill or shaft of the feather, which would be contrary to the desired object, and would make the feathers unfit for the intended purpose;

but it will simply tear and break them up in a manner to be pliably curled, and to become soft and elastic and well adapted for pillows.

I am aware that it is not new to construct paper-making and kindred machines with a cylinder and a concave, each provided with V- shaped teeth. ,I am also aware that a pulpengine has been provided with aserrated bar the equivalent of my bar hand that a woodgrinder has been constructed with a cylinder and a concave provided with V-shaped teeth, with the concave eccentrically located relatively to the cylinder, and such constructions I do not broadly claim. By constructing the cylinder and concave with grooves and securing therein the serrated bars a g, such bars can readily be removed and either replaced or others substituted in lieu thereof. The location of the concave eccentricall y to the cylinder would not be practical in a feathercrushing machine, as thereby the feathers would be crowded and compressed together by degrees as they approached the exit, and thereby the utility of the machine would be destroyed, as the teeth could not continuously operate to break and soften the quills.

What I claim is- 1. The device herein described of crushing feathers between a rotating cylinder, A, and

amass a stationary concave, D, both provided with correspondingly-shaped projecting teeth, and said cylinder being eccentricall y pivoted to the shell or concave D, substantially as and for the purpose set forth.

2. In a feather-crushing machine, the rotating cylinder A, having circumferential radial grooves, serrated bars a, forming V-shaped teeth, and the shell or concave D, having grooves and serrated bars 9 and h, and cap H, said cylinder A being eccentrically pivoted to the shell or concave D, for the purpose described,and the respective bars being secured within the grooves, substantially in the manner herein described.

3. In a feather-crushing machine, the rotating cylinder A, provided with projecting teeth, the stationary concave D, having serrated plates 9 h, the feed-table G, and cap H, with partition K, in combination with the fan M and blast-pipe L, all substantiallyas described and shown, to operate as specified.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.

WILLIAM HAMMERMILLER.
