BED-PLATE FOR PAPER-PULP ENGINES.

SPECIFICATION forming part of Letters Patent. No. 320,721, dated June 23, 1885.

Application filed April 9.0, 1885. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK S. TAYLOR, of Eiegelsville, in the county of WVarren and State of New Jersey, have invented certain new and useful Improvements in Bed-Plates for Paper-Pulp Engines, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is an end elevation of one of my improved bed-plates for papenpulp engines and the roll, the vat or tub, box, back-fall, and roll-shaft being shown in section. Fig. 2 is a plan view of the bed-plate. Fig. 3 is a plan view of the base of the bedplate, part being broken away. Fig. 4 is a sectional end elevation of the bed-plate taken through the line as as, Fig. 2.

The object of this invention is to provide bed-plates for paper-pulp engines constructed in such a manner as to be less expensive in manufacture than ordinary bed-plates, and that the cutting or wearing parts when worn out can be replaced at small cost.

The invention consists in the construction and combination of the various parts of the bed-plate, as will be hereinafter fully described, and then pointed out in the claims.

A represents the vat or tub, B the baclofall, C the roll, and D the rollshaft, of an ordinary paper-pulp engine.

To the bottom of the vat A is secured the box E, upon the upper side edges of which are formed upwardly-projecting flanges F, to form a seat for the bed-plate. The bed-plate is secured in placeby keys G, inserted between the flanges F and the side edges of the said bed-plate.

The base of the bed-plate is made in two parts, each of which consists of a vertical clamping-plate H, having upon its inner side a series of parallel projecting arms, I, the upper edges of which are a little lower than the upper edges of the plate H, and which form a support for the bed-plate J. The two parts H I, H I of the base are connected and made to clamp the bed-plate J by bolts K passing through the said plat-es H at the sides of the arms I. Between the inner ends of the basearms I is interposed a bar or block, L, of wood, to make the connection between the two parts of the base firm and rigid.

J is the bed-plate, which is cast in one piece with series of parallel rectangular inclined slots forming series of parallel inclined bars and a series of cross-bars, as shown in Fig. 2. The top of the bed-plate J is concaved, as shown in Fig. 4, to correspond with the convexed surface of the roll 0. Vith this construction the bedplate J is the only part subject to wear, and the said bed-plate when worn can be readily detached and replaced by a new one.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. The cast-metal bed-plate J, made with a series of inclined slots forming a series of inclined bars and a series of crossbars, substantially as herein shown and described.

2. The combination, with the cast-metal bedplate J, of the clampingbars H, having in Wfll'dlY-PIOJQChllJg arms I to support the said bed-plate, the wooden bar L, interposed between the ends of the arms I, and the transverse fastening-bolts K, substantially as herein shown and described, whereby the said bedplate will be firmly supported, securely held in place, and can be readily detached and replaced, as set forth.

FREDERICK S. TAYLOR.
