Description
UNITED STATES PATENT OEEICE.
FITZLAND L. WILSON, OF SAGINAW, MICHIGAN.
HOOP-CUTTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 244,155, dated July 12, 1881.
Application tiled January 13, 1881. (No model.)
To all whom it may concern:
Beit known that I, FITZLAND L. WILSON, of the city and county of Saginaw, and State of Michigan, have invented an Improvement in Hoop-Cutting Machines, of which the following is a specification.
The nature f my invention relates to certain new and useful improvements in the construction of machines for cutting hoops directly from a log ,and it consists in the peculiar construction and arrangement of the parts,
' as hereinafter more fully set forth.
Figure l is a plan view. Fig. 2 is a perspective, showing the chucks which hold the log in position and the devices for simultaneously advancing it to the knife. Fig. 3 is a vertical central section on the line of the axis ot' the spindles which carry the chucks. Fig. 4 is an end view of feed mechanism. Fig. 5 is a partial perspective of the same and the cutter. Fig. 6 is a vertical cross-section through the cutter-head, cutter, and log,'showing the inanner in which the log` is eut into hoops.
. In the accompanying drawings, which form a part of this specification, A A' represent two spindles, the axis of the one being in direct line with the axis of the other. To the inner ends of these spindles are securedthe chucks B B', the former rigidly, the` latterin the manner of a swivel. These chucks have on their inner faces steel studs or pins, which, by being forced into the ends of the logs C, will hold the same in position.
D D D2 are ways properly secured upon bedtimbers. Seated upon these ways are sliding plates E E' E2, their forward ends, a a a2, forming bearings for the spindles A A', while their rear ends contain on the under side racks,which engage with small pinions b b b2 on the shaft c. By this construction the spindles A A and their respective plates are made to advance or retract simultaneously, in the well-known manner of the head-blocks for sawmills.
E3 is a conntershaft which gives motion to the cam-wheel F. This cam-wheel has cut in one of its sides the continuous groove d, which consists of the circular portions 1 2 and 3 4, of different radii, having their centers coincident with the center of the wheel F.
e is a link, one end of which is attached to the cross-head G, while the other end engages with the stud f in the groove d, and is also attached to the lower end of the pendulous hanger Il, the latter being pivoted near its upper end to the frame of the machine by a bolt. (Not seen in the drawings.)
I is a ratchetfaced wheel journaled upon the arm J .f
K K are two vibrating radial arms with-the pawls g g attached to them, and h h are links which connect the radial arms K K with the cross-head G, and L is a guide-rod upon which the cross-head has its reciprocating motion.
The ratchet-Wheel I is an internally-toothed gear-wheel meshing with the small pinion M, and thereby giving motion to the shaft N, which carries' neary its lower end the Wormgear O, (which engages with the spiral gearing i in the rear side of the spiral guide-wheel 1),) while its lower end is stepped in the sliding block j, whereby the worm-gear O can be thrown in or out of gear. rlhe spiral guidewheel P is keyed upon the spindle A, and is provided on one side with a spiral groove, lc, and in the opposite side with the spiral gearing i, the spirals on both sides being counterparts of each other.
Q, is a hand-wheel upon the outer end of the spindle A.
R is a rigid arm, the free end of which carries the projecting stud l, which enters the spiral groove k in the wheel I.
S is a bed-piece, upon which is secured the guide T for the cutter-head U. The guide T is parallel to the spindles A A', whereby the knife-head U, to which a reciprocating movement is given, will move parallel to the spindles.
The knife V, which is adjustably secured to the knife-head U, is of the form shown in Figs. 5 and 6, its cutting-edges being in two planes which are at right angles to each other, and its four cutting-edges constituting a double knife, adapted to cut alike at the forward and backward stroke of the pitman. The knife V (see Fig. 5) has its edges o inclined from the E" isa frame, X, consisting of the two bows m m' and connecting-rods n n. The spindle A passes freely through the bow m, which is prevented from displacement by the collar 0. The spindle A' is screw-threaded through the bow m', and can be retracted or advanced by means of the hand-lever p.
In practice a log is taken from the steaming-vat and suspended between the chucks B B'. By advancing the chuck B' by means of the hand-lever p, the log is securely chucked in such manner th at its axis will coincide with the axis of the spindles. The frame X will prevent the chucks from exerting any lateral pressure upon the ways D D' D2. Motion being given to the knife-head, it Will commence its reciprocating motion, and the revolving counter-shaft E3 will cause the cam-wheel F to impart to the link e an intermittent rectilinear motion, which, by means of the ratchet-faced wheel I, will be converted into an intermittent rotary motion, and if the worm-gear O is now made to engage with the spiral gear of the guide-wheel P the latter will also revolveinterinittently,impartin g its rotary motion through the spindle A to the log G. As the stationary arm B engages with the stud Z in the spiral groove 7c, the guide-wheel P will, during its rotations, gradually be drawn in the direction of the arm It, and this movement, being followed up by the shaft A and sliding plates E E' E2, which by reason of the shaft c and pinions b b' b2 have a simultaneous movement, the spindle A' will move in the same degree as the spindle A, and thereby carry the log C toward the knife, which latter will at first only cut small strips from the log, increasing in size, until nally perfect hoops will be cut at each stroke of the knife until the log is almost entirely cut up.
What I claim as my invention isl. The double knife V, having its edges t inclined from its ends to near its middle, where said edges intersect the triangular knife c',
having its plane perpendicular to the the knife V, substantially as described, and for the purpose set forth.
2. The combination, with the guide T and cutter-head U, carrying the double knife V fv', constructed as set forth, of suitable mechanism whereby a reciprocating motion is given the knife, substantially as specified.
3. The combination, with the guide T and cutter-head U, carrying the double knifeV c', reciprocated by suitable mechanism, of the shafts A A', carrying the chucks BV B', substantially as described, and for the purpose set forth.
4. The combination, with the guide T, cutter-head U,and double knifeV/v, reciprocated by suitable mechanism, of the shafts A A', carrying the chucks B B', and mechanism, substantially as described, whereby an intermittent rotary and forward motion is given the log, substantially as described.
5. In ahoop-machine,the combination, with the shafts A A' and chucksB B', of the wheel P, having on its inner face the spiral gear i, shaft N, carrying worm-gear O on one end and pinion M on the other end, internally-geared ratchet-wheel I, pawls g g, arms K K, connecting-rods h It c, and cam-wheel F, whereby an intermittent rotary motion is given the chucks, substantially as described.
6. In a hoop-machine, the combination, with the ways D D' D2, sliding plates E E' E2,hav ing journal-bearings a a' a2 on their forward ends and racks on their rear ends, shafts A A', and chucks B B', of the counter-shaft c, carrying the pinions b b 112, wheel P, provided with a spiral groove K, and arm It, having on its free end the pin Z, whereby an intermittent forward movement is imparted to the log, sub-Y stantially as described.
