-B.F.TABBR. MACHINE FOR ROSSING BARK.
No. 37,530. Patented Jan. 27, 1863.
v mnb UNITED STATES PATENT OFFICE.
BENJAMIN F. TAB'ER, OF BUFFALO, NEW YORK.
IMPROVEMENT IN MACHINES FOR. ROSSING BARK.
Specification forming part of Letters Patent No. 37,5 30, dated January 27, 1863.
To all whom/it may concern.-
Be it known that l, BENJAMIN F. TABER, of the cityof Bufl'alo, county of Erie, and State of New York, have invented a new and [m Fig. II is a longitudinal section of same, and
Fig. III is an end elevation of same.
Letters of like name and kind refer to like parts in each of the figures.
A represents the supporting frame-work of the machine.
B represents a feed-cylinder having spurs b on its periphery for catching into and holding onto the bark, so that it may be carried along with the rotation of the cylinder to the rossing-knife, and thence to the breakers. This cylinder revolves upon its shaft .13 which shaft has suitablehearings in the main frame. There are circular grooves 22 cut in the cylinder,into which the points of the fingers R'drop, in order that the points of the teeth may pass under the bark and pass the bark to the breakers.
G is a curved and yielding pressure-plate placed slightly eccentric to the feed-cylinder, and having a greater radius than the feedcylinder, and forms a case, in part, for the cylinde'r-to work in. It is so supported in the frame that it may have an outward or inward movement sufiicient to accommodate it to the inequalities in the bark, and for this purpose it has afoot-piece at each end bearing upon the lower side pieces of the main frame, as shownat G. I There areguide-rods (two upon each end) placed parallel and one above the other, as shown at DD, which guide-rods pass through the foot-pieces O and serve togive a steady horizontal movement to the pressureplate. There are coil-springs E placed upon these rods, which bear against the foot-pieces of the pressure-plate and hold the pressureplate pp to its proper place, the springs allowing the pressure-plate to yield sufficiently for all the requirements of the unevenness and inequalities of the bark. These springs are suflioieutly strong to hold the bark to the cylinder, so that if the bark is warped or curled the pressure-plate will flatten it and hold it close to the cylinder. There is an inclined projection from this pressure-plate, as shown at G, upon which the rossing-knife F is sup ported, the knife having slots through it, with guiding pins or screws passing through the slots and into the projection G, as shown at h, to guide the movement of the knife upon the projection. There is also a series of hinged or jointed levers connected with each end of the knife, as shown at I J K. The-lever'l is hinged at one end to theme-in frame, as shown at i. It has several holes throughit,
as shown at i for connection and adjustment v with the levers J and K. The lever J is hinged to the knife, as shown at j, and to the lever I, as shown at j The lever Kis hinged to the lever I, as shown at W, and to the press lire-plate, as shown at A1 By this arrangement and connection of the levers with the knife and pressure-plate the relative position of the knife is accommodated to the varying thickness of the bark, so that the proper depth of cut is maintained, and at the same time allow the pressure-plate to yield and give back more to the inequalities and diifcrent thickmesses of the bark than the knife does, and
by changing the points of connecting the levers J and K tothe lever I the knife may be made to move back more or 'less with the pressure-plate, so as to adapt thema'chiue to every variety of bark which may be run through the machine.
AtL is represented aflap,which is connected to the pressure-plate by a suitable hinge. This flap is so put on as to leave a throat or opening over the knife for the rose to pass out. There are two semi-elliptic springs placed over the flap andbea-ri'ng thereon, as shown at M, (one at each end,) to keepi't down to its place. These springs will allow the flap to yield sufficiently for the diflerent-thicknesses of ross to pass out. I
At 0 is represented a curved stationary plate of corresponding radius to the pressureplate, but concentric with the feed-cylinder, and with the pressure-plate forms the case or shell for the cylinder to work in. This part of the case guides the bark from the pressure; plate up to the breakers. These two plates overlap each other, as shown at p, which overlapping is sufficient to allow of the movement of the pressure-plate without causing an opening between them.
At Q is represented the breaker, which consists of aseries of arms projecting from a shaft, Q with which they revolve.
R represents a series of fingers,in the form of open right-angle triangles, connected to the eross'pieees'R of the main frame, equidistant, from each other and over the dischargingmouth. The points of the fingers run in the grooves formed in the feed-cylinder, so as to pass under the bark as it comes around with the cylinder, and the inclined sides of the fin gers. turn the bark off to the action of the breaking-arms, the breaking-arms passing through the spaces between the fingers and breaking the bark in fine pieces over the edge of the stationary plate 0.
S represents the table upon which the bark is placed to be fed to the machine. I -T are rollers reaching across the pressureplate, to facilitate the easy passage of the bark to the rossing-knife. I
W is a pulley on the shaft of the feed-cylinder, and V is a pulley on the shaft of the breaker.
W is adriving'belt, which communicates motion from the feed-cylinder to the breaker.
.0peration: Power is applied to the feedcylinder'iu a common manner. The bark to be rossed is placed upon the feed-table S,'the inner bark next to the table, and run down to the cylinder. The spurs on the cylinder will catch into the bark as the cylinder revolves, and will carry it to the knife, as already described. The knife takes off the ross, which passes out under the tlap L, as before de scribed, while the inner bark is carried along to the breakers, where it is broken into small pieces suitable for g'rinding in a bark-mill. The rossing and breaking are both performed in a complete and satisfactory manner.
What I claim as my invention, and desire to secure by Letters Patent, is
1. In a machine for rosslng bark, the combination of the yielding spring pressure plate 0 with the feed-cylinder B, for the purposes and substantially as described.
2. The arrangement and combination of the rossing-knit'e with the adjustable levers I J K, for the purposes substantially as'described.
3. The combination of the breaker Q, fingers It, and plate 0 with the feed-cylinder B, for the purposes and substantially as set forth 4. The combination of the spring-fiap L with the pressure-plate C and feed-cylinder B, for the purposes and substantially as set forth. B. F. TABER.
