JOSEPH THOMAS, OF BROOKLYN, NEW YORK.

MACHINE FOR SIZING- HAT-BODIES.

Specification of Letters Patent No. 15,154, dated June 17, 1856.

To all whom t may concern:

Be it known that I, JOSEPH THOMAS, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Machine for Sizing and Felting Hat- Bodies; and I do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, figures, and letters of reference thereon, in Which- Figure 1, is a top view of my improved machine. Fig. 2, is an end view of it. Fig. 3 is a side elevation of it.

Similar letters of reference refer to like parts in all the drawings.

The vrnature of one part of my invention consists in an arrangement of mechanism giving the main wheel or driver a vibrating rotary motion which shall cause the material to be rubbed or rolled back and forth and finally discharged by the constantly advancing movement of the main wheel.

Another part of my invention consists in so combining a circular plate or shield, and table against which the material rests during the operation that the pressure is rendered perfectly adjustable.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A, is the base of the machine.

B, B, are upright posts with a suitable brace inserted between them as shown in Fig. 2 at y' to support and keep lthem firm.

C, C, are two upright posts which furnish bearings for the main wheel shaft as shown in Fig. 1.

D, is the main wheel.

E is a wheel which imparts motion to the main wheel.

F, is the main shaft on which are the wheels D and E.

Gr is another shaft passing through the upright posts B, B, having thereon the three pointed cams y y.

H and I is a forked lever one end of which is attached to the crank z, while the other connects with the wheel U.

J, J, are levers the lower ends of which support the shaft of the wheel Uwhile the upper ends swing upon the shaft F.

K is a sliding carriage frame which supports a series of ratchet rollers and slides freely in grooves placed upon the posts B, B, as shown in Fig. 3.

L, L, are vibrating levers with fulcrums at (e) see Fig. 3, which work the carriage back and forth.

M, M, M, M, M, are the ratchet rollers, one of which is seen in Fig. 1, while' the others are covered by the plate O.

N, N, N, N, N, are dogs or pawls which are carried upon pins as seen in Fig. 3 at (f) while the points catch in the grooves of the rollers M and cause them to rotate during the motion of the carriage in one direction.

O is a table for receiving the goods as they are discharged from t-he machine.

P is a cross bar attached at its ends to the straps o).

Q is a lever one end of which is fastened to the upright post B as a fulcrum and is also attached atthe center of the cross bar P, by the bolt (a) see Fig. 2.

S is a sliding weight on the lever Q to graduate the pressure upon the goods.

T is a crank wheel or pulley for propelling the wheel.

U is a small wheel which by its friction causes the wheel Eto rotate.

V is a small ratchet wheel seen plainly in Fig. 3.

W is a short vibrating lever which works upon a fulcrum pin, the lower end of which is slotted to allow the stationary pin (c) to pass through it, while the upper end is furnished with a dog 0r pawl X for working l rock upon the main shaft F, and are slotted in their ends as shown in Fig. 3.'

B', is what I call a circular adjustable plate or shield, which is plainly seen in Fig. 3.

C' is an adjustable apron or plate upon which the material rests while feeding into the machine, and which is hung on pivots at z' z' Figs. 2 and 3.

Operation: Motion being given the wheel T, the cams y, y, will strike the levers L, L, which have fulcrum at (e) and give them an oscillating motion. lThe upper end of these are slotted as shown in Fig. 3 and are attached to one of the ratchet rollers M',

Fig. l, the shafts of whichV rollers project far enough from each side of the frame to enter the slotted levers L. As this roller M', has its bearings in the sliding carriage K, it must work back and forth as the levers L oscillate. The carriage is carried back after the cams and levers have forced it forward by means of the springs (a, a,) which bear againsta pin as shown in Figs. 2 and 3. During the travel of the carriage K, (see Figs. 2 and 3) in one direction the rollers will have no motion being held by their own friction or otherwise, but as the carriage travels in the reverse direction the dogs or pawls N will catch in the ratchet grooves and cause a simultaneous movement of all the rollers and thus feed the material into the machine. Under these rollers there is an adjustable apron or table (C') Figs. 2 and 3 which will give the material any pressure required by altering the position of the weight on the lever a. Above these rollers there is another apron or table O which receives the goods as they are discharged from the machine. On the shaft G there is a crank Z (see Fig. 3) to which is attached the forked lever H, I. In these levers is placed the shaft of the wheel U see Fig. 2:-there are two levers J, J, One on each side of the wheel E, which swing on the shaft F at their upper ends, while the lower ends form the bearing of the wheel U as shown in Fig. 2. Between the lever J, on the outside of the wheel E, and the lever I, there is a ratchet wheel made fast upon the shaft of the wheel U, and also a lever W, the lower end of which is slotted and inserted upon a stationary pin (c) Fig. 3 while the upper end is furnished with a dog X. As the crank Z, makes its revolutions it imparts a vibratory reciprocating motion through the lever H, to the levers J, and consequently to the wheels E and U. These wheels 4are covered with any material to produce the requisite friction upon their peripheries. During a half stroke of the crank Z, the dog X will drag over the teeth of the ratchet wheel V and thus allow the wheel Il, to remain without motion; but during the other half stroke the stationary pin (c) Fig. 3 will cause the dog X to catch in the ratchet wheel V, and move it forward thus giving an advance movement to the wheel U, which presses upon the wheel E and causes it to advance and also the wheel D, which is upon the same shaft.

I would here remark that the wheel D, is corrugated upon its periphery. Extending nearly around this corrugated wheel is an adjustable corrugated plate or belt B', shown plainly in Fig. 3, one end of which is fastened in a suitable manner to the frame work, and is made adjustable by means of the levers A', of which there may be three or more. These levers are slotted at their ends and have rods (71 la) passing through them; and leaning against the plate B'.

\ Passing through a hole or loop in these rods (71,) is a stop or chain which is made fast at the lower lever, and thence through the other rods under the adjustable table C', to the bar or lever P where it is fastened. This bar P, is attached to a lever Q, by a bolt (d). As this lever is weighted down by moving the weight S, it will draw the corrugated plate closer to the wheel D, and also carry the apron C', closer to the ratchet rollers, and by this means render those parts perfectly adjustable as to pressure of the material to be sized or fitted.

Having thus described my improved machine for sizing and fitting hat bodies what I claim as new therein and desire to secure by Letters Patent is:

l. I claim combining with the wheel D, the wheels E and U, (or their mechanical equivalents) for giving the main wheel a vibrating motion when used with a stationary plate or bed, in order to rub the goods back and forth, and also in combination therewith the mechanism for giving the main wheel the constantly advancing motion when arranged and operating in a manner substantially the same with that described.

2. I claim combining and arranging the circular plate or bed, B', and table C', in such a manner that the levers A', (or their equivalents) and cords Z), b, the same mechanism may adjust the plate B', to the wheel D and also the table C', to the ratchet rollers and thus give any pressure desired to the goods, substantially as specied and for the purpose set forth.

JOSEPH THOMAS.
