WILLIAM FUZZARD, OF NEWARK, NEW JERSEY.

Specification forming part of Letters Patent Np. 12,386, dated February 13, 1855; Reissued July 10, 1855, No. 314.

To all whom t may concern:

Be it known that I, WiLLIiiM FUZZARD, of Newark, in the county of Essex and State of New Jersey, have invented a new and Improved Machine for Felting Hat-Bodies; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, said drawing being a longitudinal vertical section of my 'improved machine, the plane of section being through the center'.

The nature of my invention consists in the employment or use of a pair of corrugated rollers, placed in a swinging frame, in combination with an endless apron working overa driving drum or cylinder and between the corrugated ro-llers. The above parts being constructed, arranged and operating, as will be hereafter fully shown and described.

To enable others skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A, represents a rectangular frame, having a swinging frame B, secured wit-hin it, one of the pivots on which the swinging frame works, being shown at The swinging frame is of rectangular form, and is provided with two corrugated rollers, C, C', placed transversely within it. The axis of the roller, C, works in permanent bearings in the frame, B, but .the axis of the roller, C, has its bearings in slides, D, which work in grooves (b) in t-he inner surfaces of the side pieces of the frame B, the slides being operated by a screw, E, so that the roller, C', may be adjusted nearer to, or farther from tlie roller, C, as desired.

F, is a drum, the axis or sliaftof which runs in suitable bearings on the upper part of the frame, A. The drum is placed transversely on the frame A, and parallel with the rollers, C, C', in the swinging frame', B. Around the drum, F, there is an endless apron G, formed of any suitable material. This apron is of suliicient length to pass between the rollers, C, C, and extend a short distance below them.

II, is a trough or basin secured to the lower part of the frame, A, and underneath the rollers, C, C,-the length of the trough or basin corresponding with that of the Operation: The roller, S', is first moved a suitable .distance from the roller, C, by operating the screw, E, and the hat bodies to be felted are rolled up by hand, a suitable number together and placed in the fold at 4the lower part of the endless apron, G. The roller, C', is then moved near the roller C, and a rotary, reciprocating motion is given the drum, F1, by hand, or otherwise, and the hat bodies receive a similar motion within the apron, G, underneath the rollers,

C, C', and the requisite pressure is given the hat bodies against the rollers, by depressing or bearing with the hand upon the outer end of the swinging frame, B.

The advantage of the above invention is that the pressure of the rollers upon the hat bodies may be graduated with the greatest nicety. This is important, for the hat bodies when first acted upon, or when first put in the machine, are extremely tender and liable to be ruptured. By my improved machine, a very slight pressure may be irst given them, and precisely similar to that of hand pressure. After the bodies are somewhat felted and have sufficient strength the pressure may be increased by depressing the swinging frame still more, and a continuous rotary motion given the drum, F.

The hat bodies are moistened as usual before being operated upon by the `machine, and the trough or basin, H, receives the moisture expressed from them, by the pressure of the rollers, C, C".

I do not claim the corrugated rollers, C, C, separately, for they have been previously used, although differently arranged from thoseherein described; but

l/Vhat I claim as new and desire to secure by Letters Iatent is,

The employment or use of the corrugated rollers, C, C, placed in a swinging frame, B, in combination with the endless apron, G, the above parts being constructed, arranged, and operating, in the manner and for the purpose as herein sho-wn and described.
