CIRCULAR-SAW MILL.
SPECIFICATION forming part of Letters Patent No. 468,856, dated February 16, 1892. Application tiled October 19, 1889. Serial No. 327,602.` (No model.)
To @ZZ whom it may concern:
VBe it known that I, JAMEs POLK WILLIAMS, a citizen of the United States, residing at Independence, in the countyI of Kenton and State of Kentucky, have invented a new and useful Improved Circular-Saw Mill, reference being had to the accompanying drawings.
This invention relates to certain new and useful improvements' in circular-saw mills; and it has for its object to improve upon the construction and render more efficient in operation that class of circular-saw mills in which a continuous cutting motion is imparted to the saw during both the'forward and return movements of the carriage and inwhich by a peculiar arrangement of levers and mechanism to which they are connected the saw may be raised or lowered, so as to adapt it to cut from the top ofthe log downward or from the under side upward, as may be desired, thus rendering it possible to cut logs of greater diameter by the use of la single saw of small or medium size and dispensing with the use of a top or additional saw.
To the above ends and to such others as the invention may pertain the same consists in the peculiar construction and in the novel combination, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then specifically defined in the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, formapart of this specification, like letters of reference indicating like parts throughout the several views, and in which- Figurel is aperspective view-of a saw-mill constructed in accordance with myinvention. Fig. 2isabotto1n plan view of the same. Fig. 3 is a transverse horizontal section.
Reference now being had to the details of the drawings by letter, A designates the lower portion of the frame of the machine.
B B are uprightls, which are preferably made of heavy planking bolted securely at their ylower ends to the base portion of the frame, and thus serve as supports for the platform.
C is the saw-arbor, carrying at one of its ends the saw' C and upon its opposite end is provided with a pulley C2.
D and D are screw-threaded shafts, which rise vertically from the base portion of the machine vand are extended through openings formed in the platform B adjacent to and to the rear of the saw-arbor. The shaft D is journaled at its lower end within suitable journal-boxes D2, which is bolted securely to the outer face of the side timber of the base of the frame, while at its upper end it is pro-` vided with a gear-wheel D3. The shaft D is" passed through journal-boxes D4 and D5 and at its lower end extends a short distance below the lower edge of the frame of the machine. Itis provided with a screw-threaded drum DG. provided with a gear-Wheel D7, which is in all respects similar to the gear-Wheel D3 upon the shaft D.
E is a shaft entending transversely through the base portion of the frame of the machine a short distance to the rear of the saw-arbor. This shaft is provided at its outer end with a pulley E.
E2 and E3 are friction-wheels, which are keyed to the body of the shaftE at points adjacent to and equidistant from the longitudinal center of the machine.
F is a vertical shaft carrying upon its lower end a horizontal friction-Wheel E, adapted to be rotated by being brought into contact with either of the wheels E2 or E3, as will presently appear. The shaft F is provided with suitable bearings and is provided at its upper end with a pinion F3, which pinion is adapted to mesh with the pinion F4 upon the lower end of the vertical shaft E5, the upper end of which shaft extends through an aperture formed in the' platform B and is provided with a gear- Wheel F6, which meshes with the gear-Wheel D3 and also D7, as is best shown in Fig. l of the drawings.
G is a transverse shaft carrying upon one The upper end of said shaft D is of its ends 'a gear-Wheel G and upon its opposite end a similar gear-wheel G2, which gearwheel G2 is adapted to mesh with the wormgear upon the .drum D6. 1
H is a rack-bar, which is adapted to move within suitable guides H', secured to the basetimber of the fraine. The cogs` upon the lower edge of the rack-bar are adapted t0 mesh with the cogs upon the gear-Wheel G.
H2 is a tightener-pulley, which is sleeved upon a stub-shaft carried by the upright H2", attached to the rack-barI-I.
I is a transverse shaft, which is journaled within the front end of the base .portion of the machine. The shaft I is provided with a gear-wheel Iand upon its eXtreme outer end is provided a pinion I2.
J is a transverse shaft journaled within the lower portion of the frame and carrying upon one of its ends a pinion J.
K is a horizontal shaft, which is j ouriialed within the lower portion of the frame of the machine and extends longitudinally through the center of the base portion of the machine from a point adjacent to the shaft J to a'point between the friction-wheels E and E2 upon the shaft E and is provided at its front end with the disk K and at its rear end with the friction-wheel K2, which is adapted to be rotated by contact with the friction-wheel E2.
K3 is a spiral spring, which is sleeved upon the body of the shaft K, one end of said spring bearing against the journal-box K4 and its \opposite end bearing against the collar. K5
upon the shaft, thus insuring a constant pressure of the disk K against the friction-wheel J3 upon the shaft J.
L is an operating-lever, which is attached at its lower end to the shaft L', which shaft is provided with suitable bearings upon the outer face of the side timber of the base portion of the fraine upon the side adjacent to the saw-carriage and extends to the rear end of the frame, where it connects by means of the crank L2 and link L2 with the free end of the lever M, the opposite end of which lever is connected with the vertical shaft F, carrying at its lower end the frictioii-wheel F.
N is the lever which is used to control the movement of the saw-carriage. This lever is sleeved at its lower end upon the outer end of the arm or stub-shaft N, and within the enlarged central portion N2 of the leveris received the shaft J and friction-wheel J 2, carried by said shaft, the said enlarged portion N2 of the lever being provided with Vertical slots, as shown in Fig. l of the drawings, for the accommodation of the shaft and wheel.
The operationof the mechanism is as follows: Suppose-that the saw-carriage has been moved and the log carried thereby has been cut from the under side upward by the upper portion of the saw and that it is now proposed to raise the saw, so as to cause the same to cut downward from tli'e top of the log. By pressing the lever L to theright it will be seen that the shaft L will be given a partial revolution, and motion will thus be imparted through the crank L2 and connecting-link L3 to the lever M, and the frictionwheel F will thus be forced into contact with the inner face of the wheel`E2 upon the shaft E, upon the outer end of Vwhich shaft is carried the pulley E'. This contact of the frictioii-wheel F with the revolving wheel E2i n1 parts motion to the vertical shaft, upon which the wheel E3 is secured, and through the pinion F3 upon its upper end motion is imparted to the pinion F4 and shaft F5, causing the gear-wheel F6 upon its upper end to rotate the vertical screw-threaded shaftsl) and D bythe engagement with the gear-wheels l)s and D7 with the wheel F6, thus raising the saw-arbor, as will be readily understood. It will also be seen that by reversing the motion of the operating-lever L the frictionwheel F will be brought into Contact with the wheel lE2 and the several shafts will be caused to rotate in an opposite direction, thus lowering the saw-arbor.
The movements of the saw-carriage are regulated by the manipulation of the lever N either to the right or left, which movement of the lever moves the wheel J 3 to the right or left, as the case may be, upon the shaft J, the said wheel J 3 being adapted to rotate with the shaft and yet is movable thereon in the direction of the length of the shaft. This movement of the wheel J 3 causes the same to bear upon the face of the revolving-disk K at such point as may be desired, (depending, of course, upon the distance the lever is moved,) and the shaft J may be thus caused to rotate slowly or rapidly, as desired, the rate of speed depending upon'the point upon the wheel at which contact is had with the disk, and the directionof rotation of said shaft will depend upon the point of contact, as if the wheel contacts with the disk at a point to the right of the center of the disk the shaft willbe caused to rotate to the right and if the contact be to the left of the center the rotation will be to the left. Motion is imparted through the mediumof the gear-Wheel J to the gear-Wheel I', and thence by any suitable chain of gearing to the saw-carriage. As the saw is raised or lowered, the wheel G', meshing with the rack I-l, moves the latter to tighten or loosen the pressure of the wheel H2 on the belt, tlie said wheel H2 serving as a belt-tightenei.
IIaving thus described my inventiomwhat I claim to be new, and desire to secure by Letters Patent, is-
l. The combination, with the devices foi' carrying the saw, of two oppositely-.disposed screw-threaded shafts, gear-wheels upon said shafts, connections between the saw and gears and screw-threaded shafts, La gear-Wheel arranged between and meshing with said gear- Wheels, and a lever and connection, substan- IOO IIO
