The 50116431115 referred to in these Letters Patent and. making parser the same.
' thefollowing general process:
First, the splint is passed horizontally by vertical feed-rollers to a selt adjusting rotary cutter head on a vertical shaft. The knives of this cutter-head or knotcntter remove all knots or excrescences from the bark side of the hoop, preparatory (second) to the action of a second self-adjusting rotary cutter-head on a hoi izqutal shaft; which, by shaving'th'e' opposite or. face Sine,
reduces the hoop to ail-even thickness throughout its entire length. I
Third, from this the splint is .fed onward between self-adjustingcutter-heads, one above and o the hoop, to trim its edges.
' Fourth, it is finally passed between crimping-rolls, which reuderit supple and adapted to take its shape on the barrel.
The machinery for pcri'ormln these four functions is arranged and operates in data 1 as follows,-reference being bad to thedrawiug accompanying this specification.
Figure 1 is a plan view of the complete machine.
Figure 2 is aside elevation of the complete machine.
. Figure 3 is a. vertical section of the dotted line 1)", showing the shaver.
Figure 4 shows the yoke and SDriY [Ur feed-rolls 2 and 3.
Figure 5 is a sectional view, showing the edgerknives.
The frame of the machine sustains all the-working parts referred to hereafter, and consists of the sides A and B, the tpp-platc C, and the cross-bars, one of which is seen at 10, fig. 3.
The'main driving-shaft a, fromwhich the'varions parts of the machine are run,.receives power by the pulley I). I
The feed-rollers are arranged in pairs, 12, 3 4, 5 6, 7 8, on vertical, shafts, which are all driven at a uniform velocity by-the pinions c c c, figs..2 and 3, power being transmitted from the main driving-shafta tothe shaft of roll .3 (or any other roll) by the bevel-gear (Z and band and. pulley e and f.
The rolls 2 4 6 8 on the bark side of the hoop arc smooth and carried by shafts, which pass through the top plate in yieldinghoxes; These rolls are pressed,
bysprings concealed beneath the top plate against the hoop, slots being made in the top plate to allow of this motion. 1
j The rolls on the split'or face side of the. hoop are fluted and in fixed boxes, with the exception of r0113, which is free and fastened'to roll 4 by a yoke, 11, fig. 3, containing a spring, as shown in fig. 4. The rolls are placed in position to feed the hoop to toe cutters, one .pair before each cutter-head.
' The splint is entered between the first pair of rolls 1 and 2, and passes between the cutter-hcad-D, fig. 1, and the roller g, which-is sustained by a stud bolted to the top plate, and supports the hoop against the stroke of the knives of the cutter-head. The course of the hoop in passing through the machine is indicated by dotted lines in the drawing.
Th'e term/.11 shaft 71-, fig. 2, carries the cutter-head D,anrl is mounted in a standard, E, -by a box at to and bottom or the standard.
The shaft is driven from a pulley,,j, on the main driving-shaft bythe twisted belt it running under the guide-pulley l, fig. '2, and around the pulley G on the shaft. The standard E is recessed to receive-the pulley G,
- and is swung on pinions n and n, fig. 2, ,fitted'into earpieces 0 and o,which are attached to two of the crossbars, in order to admit of its upper and moving to and from the splint, the top plate 0 being cut out to admit of this motion, fig. 1.
The centers of the piuions n n are in the line of the pull ofthe drivipg-helt The standard and the shaft "and cutter-head which it carries are pressed toward thehoop by the spring 2', fig. 1, andthe cutter-head is controlled in its action upon the 11001) by the yoke or bearing frame' seen in figs. 1 and 2, above the top plate of the machine. Thisyoke is free to turn on the'upper end of the standard, independent of the shaft and cutter-head,and is composed of five pieces: the semicircular box F, surrounding the cutter-head D, the upper plate q, (whiohis removed in fig. 1,) the lower plate 1*, the roller or forward rest s, and the after-rest t. These various parts are shaped and bolted together, as shown in the drawing, the roller s turning freely about a bolt, the upper end of which is prolonged into a handle, for convenience of withdrawing the cutter-head when-entering the hoop.
The lower plate '1' is bored to adapt. it to the end of the upper box of the standard E, and the upper plate q is boxed on the end of the shaft h.
The rest t is fitted to the interior of the piece 1 to which it-is secured by a bolt and slot. to make it adjustable.
The knives of the cutter-head D are slightly coucave on their cutting-edges, to adapt them, in some firmly against the hoop by the spring i, and the rest's is-placed' far enough away from the cutter head (in the direction from which the hoop is fed) to admit knots and excrescences between itand the cutter-head, and will act as a guide to indicate the bark line afterthe knot has passed under it, it is evident that knots or excrescences .on the bark side of the hoop will be removed no deeper thanthe general line of the bark surface.
The freedom of the yoke on the standard and shaft allows the rollers'to move over knots on the hoop passing under it without lifting the rest t off, and the roller 3 refinds the book-line, so as to guide the cutterhead in removing the knot.
It is'also evident that the yoke will travel along and adapt itself to the varying curves of the hoop, and that nothing that should be cut away can escape the action a of the knives of the cuttenhead D.
The lower plate 1* of the yoke-frame is prolonged into an arm, which rests against a block fastened to the top plate a", figs. 1 and 2, in order to facilitate the withdrawal of the cutter-head D from the hoop by means of the handle shown in fig. 2. This block 0" also supports the hoop in the proper position.
The splint, now free from knots and excrescences on the bark side, passes through the second. pair of rollers 3 and 4, and ispresented to the cutter-head H, shown in figs. 1, 2, and 3. This cutter-head is intendedv to shave the face or split side of the hoop, and revolves on a horizontal shaft, I, which is mounted in the boxes J and K, and driven from the wheel L on the shaft (1, by the belt M. p
The shaft 1 is free to play cndwise through its mounting boxes, and the pulley on it can play through the belt. The splint is held against the knives of the cutter-head H by the roller m.
Th-is roller is mounted in a frame, 1), fig. 3, sliding on connecting-rods u and c, which are supported parallel to the shaft I bystandards 'w and x, fixed to the top-plate, so that the connecting-rods. lie one above and one below the top. plate. These rods are connected with each other at each .cn'd by ties y and z,
, and at the further end of the shaft I are connected with it by a box, a, in the middle of ties.
The shaft I is grooved in the bearing of the box a,
" and the box-is babbited around it, so that the shaft may rotate in it, but not play through it endwise', the object of the box being to compel the shaft and cutter-head-tdplay backward and forward along with the parallel rods wand 21. V
A rod, 1), fig. 3, screw-threaded through the tie y, connects the sliding frame 15, which carries the roller m with the"connecting-rods a and v,'and also controls its position on' them.
For convenience'of adjustment, a wheel and handle, 0', are fixed to the end of the rod. By this arrangement the cutter-head H- and the roller m are coupled together by the conneetingaods u and o, and the distance between them increased or decreased by turning the rod 7; in the thread thronglrthe tie y.
Spiral springs are placed on the connecting-rods u and v at d, which, pressing against the-fixed standard :0, and acting through the tie z and the box a, draw theshaft I and eutter-hcad H away from the splint.
The face ofthecutter-head His hollowed out,.so as togive room for the fixed rest 6, which is bolted to the top-plate of .t-he machine, and supports the hoop under the downward stroke of the knives of theouttcn head. The line of the feed of the hoop is slightly changedbetween the second and third pairs of rollers, as shown by {the dotted lines, fig. 1, the object being to prevent the hoop from receiving the, upward stroke of the knives of-the cutter-head H, and it being necessary, at the same time, that the hoop should pass through the edger-knives parallel to the length of the machme. -Another fixed rest is placed on the top plate at f, figs. 1 and 3. The splint passes in front of the rest f and between the roller m and the cutter-head H, the
space between which, being defined as described by the rod 1:, is'the thickness of the shaved hoop. The tendency of the springs (1' being to withdraw the cutter-head H from the splint, the roller m bearing against the splint, holds the knives to it, and the fixed rest-f resists the pressure.
As the splint passes through, it is thus not only reduced to the definite thickness fixed by the distance between the roller m and the cutter-head H, but the roller acts as a guide and bearing against the bark, follows all its varied curvatures, keeping the cutterhead obedient to it and parallel to the bark surface, pulling the cutter-head to it or allowing it to fall away from it in accordance with such surfiice, however varied or crooked.
The lap is cut on the hoop by the operatocturning the wheel 0', so as gradually to .reduce the distance between the roller m and the cutter-head H, as the end of the hoop passes betweenthem.
The hoop, now freed from knots and shaved throughout to an even thickness with the line of .the bark,
' passes between the feed-rolls 5 and 6, and is immediately subjected to the action of the edger-knives N and O, figs. 1 and 5, which are intended to remove cxcrescenccs from its edge.
These knives are also self-adj nsting, being held against the hoop by a spring, and controlled; in their action upon its edge by a movable yoke, thereby forming a combination of parts which operates in a manner substantially similar to the knot-cutter already described as forming part of this machine.
' The edger-knives are two in numbeiyand consist of rotary cntter-hcads N and O, fig. 5, mounted horizontally in double swinging frames d h, fig. 1, which turn independently of each other on the horizontal axis'iQ-and'are placed one above and one below the hoop.
The lower cutter and frameswings in an opening made for it in the top-plate O. I
The cutter-heads rotate on shafts placed near the free ends of the swinging frames, and are driven by belts j k, figs. 1 and 2, running over flanged pulleys l' m, fig. 2, on the cutter-head shafts and corresponding pulleys on the shaft By this arrangement, the belts being radial, their 7 -tension is not altered by the movement of the swinging frames.
The belt j is twisted, in order to give motion in the proper direction to the upper cutter-head N.
The small shaft 11 is driven directly from the main driving-shaft by the belt a, and pulley 0'.
Outside the frecend of the upper swinging frame is a double yoke, p, figs. l, 2, and 5', which is free to turn about the center on which the edger-knives rotate.
The two sides of this yoke extend beyond the outter-hcad N, and are joined at their ends by crossbolts, carrying rests q and 10, which bear against the edge of the hoop when the machine is in operation,. in front of and behind the knives, and prevent their cutting into the hoop beyond a straight line joining the bearing edges of the rests.
The forward rest, '11), is adjustable by a} slot in he side-frame of the yoke, and the after one, Q, is simply
