Specification of Letters Patent.
Patented Aug. 13, 1907.
Application led August 12, 1905, Serial No. 273,965. Renewed January 21, 1907. Serial No,l 353,366.
To all whom it may concern:
Be it known that 1, EDWARD F. SMITH, a citizen of the United States, residing at Corry, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Bark-Mills; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to'which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.
My invention relates to improvements in bark-mills, and consists substantially in the construction and arrangement of the parts thereof in such a manner as to produce a bark-mill which not only rapidly cuts bark into very fine shreds, but in operation is free from the dust ordinarily produced by bark mills in their operation.
The features of my invention are hereinafter fully set forth and described, and illustrated in the accompanying drawings in which:
Figure 1 is a view in elevation of my improved barkmill with one section of the cutter-plate removed. Fig. 2 is a view iu elevation of the forcing wheel of my improved bark-mill, looking at the under side thereof. Fig. 3 is a vertical section of my improved bark-mill with the shaft step and driving mechanism broken away. Fig. l is a transverse section thereof on the line x-x in Fig. 3. Fig. 5 is a transverse section thereof on the line y-y in Fig. 3. Fig. 6 is a transverse section thereof on the line z-z in Fig. 3. Fig. 7 is a plan view of one of the cutter plate sections. Fig. 8 is a sectional view of the same on the line w-/w in Fig. 7.
In these drawings illustratingmy invention, A is the spider shaped base section of the machine, through the center of the hub A of which there is a shaft opening A2.
B is the hollow intermediate cylindrical section, and C the upper or hopper section.
The intermediate section B is secured to the base section A by means of bolts a passing through ears b on the section B and through the outer ends of removable radial arms a and into the base section A, so that the intermediate section B is raised by the radial bars a a sufcient distance above the base A to permit the radial insertion and removal of the sections D (see Fig. 7 of a cutter plate resting and supported upon the arms of the spider-shaped base between the radial bars a, the inner ends of said radial bars being secured in notches a2 in the central hub A of the base A.
The sections D of the cutter-plate are secured `in place between the bars e by means of keys passing through ears b on the section B, ears d on the cutterplate sections D of the cutter-plate, and ears a3 on the base A, so that the sections D of the cutter-plate can be readily removed and replaced. The cutter-plate sections D, (Fig. 7) are substantially quarter sections of the entire cutter-plate, having ribs d projecting above and around the outer edges thereof, and are provided with radial slots d2 in which are mounted cutter blades D secured in place by suitable bolts d3, which blades project slightly above the upper surfaces of the sections as illustrated in Fig. 8. Narrow slots d" are also made through the sections D between the cutter-blades D to admit of the passage of fine particles of bark therethrough.
lThe intermediate section B has on its inner surface vertical ribs b2 as shown in Figs. 3 d: 4, and in the upper part of this section there is a spider E which has a central hub E with a shaft bearing therein.
On a vertical shaft F passing through the bearings in the hub E in the spider E, and the hub A in the base, there is mounted in the section B over the cutter plate sections D and radial bars a a forcing-wheel G having inclined curved arms G provided with ribs g on the under surfaces thereof, as illustrated in Fig. 2. The outer ends of the arms G are preferably united by a cylindrical rim G2 provided with vertical peripheral ribs g which run adjacent to the ribs b2 on the inner surface of the section B. The forcing-wheel G revolves in the direction of the arrows (see Fig. 4) and operates to crowd the bark downward upon and against the edges of the cutter blades D which shave it into thin slneds, and the curved shape of the arms G and the ribs g thereon, operate to prevent the bark being ground from being forced too far outward by the centrifugal action of the wheel G.
ln the upper section C of the machine I make the ordinary inwardly projecting breaker arms C, and on the shaft l secure the ordinary breaker arms F which are rotated between the arms C to break up the bark in the ordinary manner.
Below the base l secure a circular receptacle H of the usual type for receiving the ground bark, provided with a discharge spout H and mounted therein upon the shaft F are revolving arms or sweeps h to convey the ground bark around to the spout H where it is discharged.
I have omitted from the drawings the usual stepbearing for the lower end of the shaft F, and the mechanism for driving the shaft F, as these parts are of ordinary and well known construction, and form no part of my invention.
I have thus shown and described a convenient mechanism embodying my invention, but it is obvions, however, that many parts thereof can be modified in their construction and arrangement without departing from the spirit of my invention.
Therefore what I claim as new and desire to secure by Letters-Patent is:
l. The combination in a bark-mill of a cutter-disk made in sections radially removable from the mill, cutter-blades in said sections, a wheel revoluble over the cutter-disk sections, curved arms 4in said wheel arranged obliquely to the cutter-disk, and ribs on the under surfaces of said oblique curved wheel-arms, substantially as set forth.
2. In a barlemill a wheel adapted t0 be rotated over cutters, arms in said wheel arranged obliquely to the cutting disk and curved forward in the direction of the rotation of the wheel, and ribs on the under oblique faces of said arms, substantially as set forth.
3, ln a bark-mill, a spider shaped base section, removable radial bars on the top ot' some of the arms of the base, a hollow section secured to the base on top of said removable bars, and cutter-plate sections adapted to be radially inserted between the base and the section secured thereupon, substantially as set forth.
4, In a bark-mill, a cutter-disk composed of sections radially removable from the mill, radial slots in said Sections, cutter-blades secured in said slots, substantially as set forth.
5. The combination of a spider-shaped base, an intermediate hollow cylindrical section having vertical ribs on its inner surface, secured to and above the base, removable cuttcrplate sections adapted to be removably secured bei tween the base and said intermediate section, an upper hopper section secured to the top of the intermediate see tion, inwardly projecting breaker arms in said section, a vertical central shaft mounted in said base and intermediate sections, breaker arms thereon operating between the breaker arms in the hopper section, a wheel mounted on said shaft Within the intermediate section of the mill, curved inclined arms in said wheel adapted to operate in close proximity to the cutters in the cutter plate sections, a vertical rim joining the outer ends of the wheel arms, and vertical ribs on the periphery of said rim operating in close proximity to the ribs on the inner surface of the intermediate section of the mill, substantially as set forth.
ln testimony whereof l affix my signature, in presence ol two witnesses.
EDWARD F. SMITH.
