IMPROVEMENT `|N FULLING-lvnvLLs.`

Specification forming part of Letters Patent No. 175,641, dated April 4, 1876; application filed February 14, 1876.

To all 'whom 'it may conce-rn Beit known that I, JOEL M. BALDWIN, of EvansMills, in the county of Jefferson and State ot' New York, have invented a new and ImprovedFnlling-Mill, ot' which the following is a specilication My improvement in l'ulling-mills consists, essentially, of a shaft ruiming-through a middle opening in4 the hammer-heads, and working them by an eccentric in said opening, whereby a good deal ot' space is economized, as compared with the crank-pitman arrangex-nent, the mill can run faster, and the whole contrivance can be located above the floor without inconvenience7 whereas the pitman and crank arrangement has to be located in a pit to beout ofthe way.

My improvement also consists ot' a construeiion of thc'box and framein part of metal, making a more permanent and desirable mill than the Wood mills, which, owing tothe damp localities in which they are located, and the nature of the Work for which they are employed, soon rot away.

Figure 1 is a longitudinal sectional elevation of' my improved mill, taken on line x a: ot' Fig. 2; and Fig. 2 is a horizontal section ot' Fig. l on line y y. Similar letters ot' reference indicate corresponding parts.

A represents the hammer-heads, which are constructed ot' metal, with a large middle opening, B, through which the shaft C passes, and in which is an eccentric, D, for working them. G represents bearing-pieces for the eccentric to act on, which are pivoted at H, and have adjusting-screws I to take up the Wear. This arrangementis very compact,and it Works easier and is capable ot' running much faster than the other. The hammer-bars J arm/pret'- erably, made ot' wood, in orderto have thc reqnisite stii'ness and light weight, and they are pivoted to a wood cap, L, which, being located above the mill high enough to be dry, does not need to be of metal. The cap is mounted on a metal frame, N O. The end plates l? of the mill are made ot' metal, also the bottom plates Q, the metal being of some non-corrosive composition 5 but the side plates R, which may 'be readily changed, may be made of wood.

Having thus described my invention, I-claim as new and desire to secure by Letters Patentl. The combination of the driving-shaft C, ececntries D, and hollow hammers A, substantially in the manner described.

2. The adjustingbearing-plates G, in comA bination with the hammers A and the eceeutries D, substantially as specified.

3. rIhe metal bottom plates Q and end plates P, Wood side plates It, metal frame O N, and wood cap L, combined and arranged substantially as specified.
