MACHINE F OR SAWING HOOPS FROM POLES.
SPECIFICATION forming part of Letters Patent No. 286,173, dated October 9, 1883.
Application filed June 27, 1883.
To aZZ whom it nmy concern/.-
Be it known that I, WILLIAM 'Bow'KER, a subject of the Queen of Great Britain, and a resident of Somerville, in the county of Middlesex, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Machinery for Sawing Hoops from Poles and Reducing the Knots thereof; and I do hereby declare the same to be described in the following specification, and represented in the accompanying drawings, of which Figure l is a side elevation of a machine provided with three endless band-saws for re moving three hoops at once from a pole, it also having mechanism for reducing the knots of such pole. Fig. 2 is a front elevation of the mechanism for reducing the knots of the pole, such figure showing the mechanism for moving laterally the cutter-arbors to facilitate the introduction of a pole between them. Fig. 3 is a front elevation'of the knot-reducing mech anism, with Fig. 4 below it, representing a top view of such mechanism. Fig. 5 is a longitudinal section; and Fig. 6, atransverse section of one of the knot-cutter arbors, such figure showing the cutter thereof and its vibratory mouth-piece, to be described. Fig, 7 is a top View; and Fig. 8, a front elevation, and Fig. 9 a transverse section, of knot-reducing 3O machinery provided with two cutters and their vibratory mouth-pieces. Fig. 10 is a top view, and Fig. 11 a front elevation, of knot-dressing machinery having but one cutter and its vibratory mouth-piece.
The nature of my invention is duly defined in the claims hereinafter presented, a distinctive feature of it being the vibratory mouthpiece adaptcd to each cutter-arbor.
In Fig. 1 of the drawings the three bandsaws of a hoop-pole sawing-machine are shown at A, B, and G, such mechanism being of the kind described and represented in the United States Patent No. 257,918, granted to me 011 May 16, 1882. The hoop-pole is exhibited at P.
In front of the sawing-machine are the three cutter-arbors D, each of which is provided with a drivingpulley, E, duly fixed on it. One of these arbors is horizontal and between the others, each of which is inclined at an an- 5o gle of sixty degrees to the first one, and is sup (No model.)
ported in and by one of two arms, F, such arm being at its lower part pivoted to one of two stationary standards, G. Thehorizontalarbor is supported by a standard, H. Each arbor has extended through and beyond it, transversely of it, a cutter, a, (see Figs. 5 and 6,) such cutter being held in place by a set-screw,
b, screwed into the arbor endwise thereof, and against one edge of the cutter. There is to each arbor and its cutter a chambered vibra 6o tory mouth-piece, I, within the chamber cl of which the cutter, while in operation, revolves, and in revolving projects through the rectangular mouth or slot 0 of such mouth-piece. This mouth-piece, formed in its transverse section as shown in Fig. 6, is pivoted at its ends upon the cutter-arbor, so as to be able to turn or vibrate freely thereon. The hoop-pole in being out passes againstthe curved outer surface of the mouth-piece, and at the same time crosses the mouth 0. In so doing any knot projecting from the pole and carried across the mouth a will enter such month more or less and be trimmed or out down or reduced by the cutter, the mouth-piece vibrating or adapting itself to the irregularities in the surface of the pole as the pole may pass along by it to the saws. From the mouthpiece the pole passes endwise to the saws, and by them will be slit,
so as to remove three hoops from it, the remaining or central part of the pole being reduced to a long triangular prism, or what is substantially such.
For moving the arms F laterally to facilitate introduction of a polebetween the cutters, there 8 5 is employed with such arms a mechanism which may be thus described: Upon a rod, a, sustained by two stationary hangers, f f, (see Figs. 1 and 2,) are two tubes, 9 g, the rod going through their bores. From one of these tubes an arm, 0 h, extends, as shown, another such arm, h, being extended from the other tube. These arms h h are connected by links z z" with a bar, It, the links being pivoted to the said bar and arms, and all being as represented. A rope, 9 5 Z, passing over a guide-pulley, m, supported in a hanger, n, is attached at one end to the bar It and at the other to the end of an elastic band,
0, of steel, arranged with reference to a rotative pulley, p, in manner as shown. Thisband, 10o
on its side next the periphery of the pulley,
l 4 as to cause it to move the lever H in a man ner to move the slide G, and thereby move its cutterarbor away from its fellow arbor.
should be faced withleather or some other suitable material, and there should be a spiral spring, connected with the band, to draw it out of contact with the pulley, which in re- "olving will move the band so as to pull upward the links M and the arms h' h, the links at their j unctions with the said arms being connected with the arms F F by cords 88. In rising the arms h h will draw the arms F F in opposite directions relatively to each other, and thereby cause the mouth-pieces I I to be so moved.
In Figs. 7 and 8 one of the cutter-arbors D D is shown as supported in a slide, G, to which-a knee-lever, H, is adapted, as shown. On the longer arm of such level-is a sliding weight, I; Above the said arm of the lever is a rotative pulley, An elastic band, 0, extends up from the arm to the said pulley, as shown. A spiral spring, 1", serves to draw the band away from the pulley. At its upper end the band has a rope, t, extending from it over a pulley, m, and to a pedal, K, all being arranged as shown. 0 will be drawn into contact with the pulley p, which, in revolving in the direction denoted by the arrow thereon, will so act 011 the band The I object of having the elastic band movable off the pulley is to prevent the pulley, which is On depressing the pedal the hand to be'supposed tobe in constant revolution, from acting on the band to wear'it or move it improperly.
In Figs. 7 and 8 the vibratory mouth-pieces of the cutters of the two arbors are shown at I I as having in front, as well as in rear of them, a horizontal guide-roll, M, to support the pole while being passed between the said mouth-pieces.
In Figs. 10 and 11 but one arbor D is shown as having aside of its vibratory mouth-piece with cutter-arbors, and the knot-cutters and their inclosing vibratory mouth-pieces adapted to the arbors, in combination with means, such as described, for moving the arms in opposite ways, as set forth.
,I a vertical guide-roll, N, and below such a horizontal guide-roll, M.
