HAT FELTING AND SIZING MACHINE.

Application filed December 6, 1883.

To all whom it may concern:

Be it known that I, THOMAS LONGSHAW, a citizen of the United States,a'nd a resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Hat Felting and Sizing Machines, of which the following is a specification.

My invention relates to that class of machines which are used in the process of hatmaking known as felting or sizing. This part of the work is generally performed by hand-labor, which is slow and tedious, and where-machinery has been applied it has met with serious objections by spoiling the stock;

- and when performing the work satisfactorily by machines the product is so small in advance of hand-labor that it does not repay the expense of constructing the machines.

The object of my invention is to devise and construct a machine that will meet all the requirements of the process, and perform the work more rapidly and successfully than has been done heretofore. I attain this by passing the roll of hats between a revolving drum and a series of small rolls fixed to a suitable frame around the said drum,and said rolls I provide with a suitable adjusting device for increasing or decreasing the space between the rolls and the drum uniformly throughout the whole of the circle, which is an essential feature, as the roll of hats require an even pressure throughout the process of sizing; and proper provision is also made for keeping roll of hats warm, which will hereinafter be more fully explained, reference being had to the accompanying drawings, in which- Figure 1 represents side elevation of felting and sizing machine. Fig. 2 represents plan view of same. Figs. 3, 4t, 5, 6, 7, 8, 9 show several different ways of constructing the drum. Figs. 10, 11, 12 show different forms of small rolls.

Similar letters refer to similar parts throughout the several views.

A represents frame; B, drum; 0, watertank; D, pressure-rolls; E, rolls of hats.

The drum B is supported by suitable bearings, a, on the frame A, and is revolved by the belt-pulley F in the direction of arrowpoint to the inner side of the frame A at b.

PE.-CIZ EGATE)N forming part of Letters Patent No. 317,555, dated May 12, 1885.

(N0 model.)

The levers G are pivoted, and to the other end of the said levers is attached the pressurerollers D D, moving to and from the drum B by the levers G, swinging on the pivot 12, and said rollers are retained and adjusted to any desired distance from the drum B by the circular frame H, having therein slots f for the reception of the protruding pins d on the levers G. The said frame H is supported and rotated on the axle of the drum B by suitable arms, H.

On the upper part of frame H is an arm, H extending above the frame A, to which the swivel-nut e of the adjusting-screws his attached. By turning the adjusting-screws h in either direction the nut e will travel forward or backward,rotating the frame H around the drum B, and changing the position of the rollers D uniformly throughout the whole circle or series by the pins (1 on lever G, moving freely in the slots f of the frame H, and the distance between the drum B and the pressurerollers D will be equal in any position they may be placed.

The pressure-rolls D may have a slide attached at each end, instead of the lever-,whieh will move to and from the drum B in a radial line by proper guides on frame A, and operated uniformly by projecting pins on said slide engaging with oblique slots in frame H.

The machine is placed in a tank, 0, of water,

which immerses the lower part of same to the height of water-line, and is kept to any desired temperature by steam-pipes Z. steam is also admitted into the drum D to warm it by the steam-pipe s, passing through the spindle of the drum B, heat being an important featurein manipulating the goods. To operate the machine the drum B is revolved in the direction of the arrow-point. The roll of hats E is fed in from the table K, and is carried around the drum B, between the same and the pressure-rolls D, and is delivered into the slide or trough K, and so continue until the batch has all passed through the machine, when they are examined and again rolled up and passed through the machine in the manner described, the space having been properly adjusted between the drum B and pressure'rolls D by the screws h, as heretofore described.

Ajet of In some some instances it may not be essential to revolve the drum continuously in one direction, but to make part of arevolution, and to reverse and revolve it inthe opposite direction a part of the distance traveled in the forward direction.

The face of the drum B may be constructed in various ways by grooves or projections, as shown in Figs. 1, 3, 4, 5, 6,7, 8,9. In Figs. 1, 5, 6, 7 the face of drum is grooved in different forms, and are parallel with the axis. In Fig. 8 the grooves or projections are annular. In Fig. 9 they are at an angle. In Fig. 3 theface of the drum consists of a series of small rolls rexwlving freely in the head or end of drum. In Fig. 4 a series of rolls are placed in a suitable frame.

Around the drum and on the periphery of the drum a rubber tire, a, is fixed, which revolves the small rolls by frictional contact with same.

The face of the drum may be covered with smooth or serrated rubber, if desired.

Figs. 10, 11, 12 show different forms of small pressure-rollers D.

I am aware that hat-rolls have been sized by revolving them between a series of pressurerollers placed around an oval shaped disk or drum; but I am not aware that hat-rolls have ever before been passed between a corrugated revolving drum and a series of pressure-rollers adjustably fastened to the inner circumference of a circular rotating disk or frame, as shown, and heretofore described.

\Vhat I desire to secureby Letters Patent 1. In ahat felting and sizing machine, with a revolving drum and a series of pressurerolls, the levers G, pivoted to the main frame A at a point, I), tangent With the periphery of the drum and attached to the roller D,and connected by slots or pins to the moving frame II, for adjusting the rollers D to or from the drum 13, substantially as and for the purpose specified.

2. In a hat felting and sizing machine with a revolving drum, the movable frame or disk H, rotated on the axis of the drum, and provided with slots or pins connecting with the levers G, and operated by the screws h and swivel-nuts e, substantially as described.

3. In a hat felting or sizing machine with a revolving drum, the lever G pivoted to the frame A at b, and attached to pressure-rolls D,

being connectedto the movable frame or disk H by slots and pins, the said frame H rotating on the axis ofthe drum B,and operated by screws h and swivel-nuts e, substantially as and for the purpose specified.

4. In a hat felting and sizing machine, the revolving drum B, with corrugated or plain surfaceplaced inside of the series of adjnstable rolls DD, substantially as and for the purpose specified.

5. In a hat-felting and sizing machine, the rollers D D, placed along the inner circumference of the rotating frame H, in combination with the levers G, frame A, and rotating frame H, substantially as and for the purpose set forth.

Signed at Bloomfield, in the county of Essexand State of New Jersey, this 4th day of December, A. D. 1883.
