IMPROVEMENT IN BED-PLATES FOR PAPER-MILL ENGINES.

Specification forming part of Letters Patent No. 178,205, dated May 30, 1876 application iiled July 24, 1815.

To all whomjt may concern:

Beit known that I, WILLIAM E.'TAYLOR, of Fulton, in the county ol' Oswego and State of New York, have invented a new and valuable Improvement in Plates for Paper-Mill Engines; and I do hereby declare that the following is a full, clear, and exact description of the construction andoperation ofthe same, reference being had to the annexed drawings, making a part of this specification, and'to the let! ters and figures of reference marked thereon.

4Figure 1 of the ,drawings is a representationof a plan view of my plate. Fig. 2 is an end view of the same, and Fig. 3 is a transverse vertical sectional view thereof'.

This invention has relation to the bed-plates against which the rotary cutters of a paperpulp engine Operate to reduce the rags; and the nature of my invention consists in the arrangement between two parallel caps or plates, of a suitable length to fit the roll, of a number of diagonal cuttingfplates with intermediate filling-pieces of wood, all of which cutting-platcs are parallel to each other and are secured to the base ofthe box by a process of casting, as Will be fully understood from the following description.

For the purpose of `more fully representing my invention and im provement,Ihave shown, in Fig. 1,. the bed-plate applied in a paperpulpenginc with the cutting-roller. removed. It will be observed that all of the cuttingplates a are diagonal to the side-s or caps A A of the box inclosing them, and that these plates a are parallel to. each other 'from one end to the other of said box, with thin wooden. strips or filling b between them. Y The cutting-plates a are arranged with reference to the rotation of the cutting-roller, so that the rags will be worked toward the midfeather,77 or central partition, which will cause the rags in the current to turn over and more thorpassed through said blades and also through the lianges of the bed B.

The bed-plate or revolving cylinder-is adi' justable vertically upward or downward, to allow for the wear of the knives in the operation lof the machine.

The metallic knives in the bed-plate would obviously be less liable to wear from friction than the wooden lling, which latter, it is found in practice, is worn away more Vrapidly than the knives, by the friction of the rags agitated by the beater, on the wooden filling, thus always leaving the ,knives to'project above the wooden lilling.

What I claim as new, and desire to secure 1 by Letters Patent, is-

' As a new article of manufacture, a bed-plate for paper-pulp engines, consisting of the parallel plates A A, the diagonal cutting-plates a., secured to the base of the box, as described,

and the intermediate filling-pieces of wood, all constructed and arranged for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of tw'o witnesses.

WILLIAM E. TAYLOR.
