At the opposite side of the machine, upon the extended planer-arbor e, are secured the pulley E and trimmingsaw F, hereinafter described. The pulley E is connected by a belt, as shown in Figs. 1 and 3, with a pulley, I on a parallel shaft, 1, extending across the machine below, and provided at the opposite end with a pulley, 1 which is connected by a belt with a pulley, J on the nearest mandrel of the doweling-bits J J, which are thus driven from the planer-arbor e.
Passing to the opposite side of the machine, G represents the trimming-saw carriage, supported and arranged to be moved parallel with the plane of the saw F upon ways 9 g, resting on and secured to brackets G G, extending laterally from the frame N of the machine. Across one end of said carriage is secured the guard g, to the extended end of which. at the outer side of said carriage, is adjustably attached the gage g, by means of which the blanks are trimmed to a uniform standard size to be received into the carriage A and operated upon by the cam B of the gage plate or frame B. The guard 9' (shown, for convenience of illustration, at the front or advancing end of the carriage G) will in practice be attached to the rear end of said carriage, or to the end thereof nearest the front of the machine, as shown in Fig. 1. I
A is the carriage by which the blanks are carried over the planer-cylinder E and deposited between the clamping-heads O O, to be operated upon by the rounding-heads. The sides of the carriage A are tongued or beveled, and work in similarly-grooved ways formed by the top of the frame N and by the beveled capplates n n, as shown most clearly in Figs. 3 and 12.
a a are dogs secured at one side of the machine in the side rail of the carriage and at the other in a laterally-adjustable bar, A On each side of the carriage said dogs a a pass through perforated plates D D,which are held by springs d d in their normal position in advance of the points of the dogs a a, and force the heading-blanks off from said dogs when, the sliding bar A is released. A is a cam provided with ajointed handle, a, and'mounted upon the adjacent side rail of said carriage in position to engage and move the dog-bar A inward, while springs a a (shown in Fig. 1) move said bar A outwardly and retain it in contact with said cam. a, is a spring secured to said carriage and arranged to engage an angular projection on said cam A. A is a rack formed upon or secured to opposite side of said carriage.

Said bars heads of vertical stems c c, which in turn rest upon spiral springs c c, inserted in cylinders O 0, formed upon plates 0" O", secured to a cross-girt, N, of the frame N of the machine. The stems 0 c are retained in the cylinders O G, and the upward movement of the bars U G is limited by lock-nuts c c on the ends of said stemsprojecting below said cylinders, as show n in Figs. 4 and 11.
E is the planer-bed, set with its upper face at the same lev'elwith the cutting-line of the planer E, so as to support the blank-head and relieve the dogs from the strain caused by planing. The planer cylinder E, being set obliquely across the machine, not only secures the advantage of a shear cut, but by carrying the saw-carriage Gout from the machine gives room for the operator without unnecessarily extending the planer-arbor e.
e e are dogs formed upon or attached to the ends of aspring,which is adjustably secured at the center by means of a slotted plate, 6 to the under side of the bed E as shown in Figs. 1 and 4-, for making headings of different sizes. They project above the rear edge of the bed E and are beveled on their front edges, so as to be forced down by an advancing head and allow the same to pass between the clampingheads 0 O, as seen in Fig. 4.

t shank of said tooth t is provided on the outside with a right angled projection, 16, split to receive one end of the spring 1., which is secured at its other end to said gear T. A pin, t", formed on the opposite side of said sliding tooth t, at right angles thereto, passes through a radial slot, t, in gear '1, as seen in Fig. 10, in position to be engaged by the cam V, which is loosely mounted upon the shaft (1 just inthem off when the holes have been bored.
side of said gear and held in contact there with by the collar 12.
Upon the outer side of the gear U are formed or attached at intervals spurs a u, to engage the tooth t, beveled at the end to readily slip off from them at the proper time. The cam V is formed with an arm, awhich is connected by a rod, o,with the upturned crank M on the rock-shaft M, passing transversely across the front of the machine and provided at the opposite end with the depending crank M, as seen in Figs. 1, 2, 4, and 6.
M is a lever fulcrumed to the frame N of the machine and connected with the crank M, as seen in Fig. 2.
m m are stops secured in the adjacent side of the frame or cap-plate n.
m is a dog pivotally secured to the adjacen side rail of carriage A, and arranged to engage said lever M when the carriage approaches the front of themachine on its return from the rounding mechanism.
My improved machine operates as follows: The sections of which the heads are to be made, having been first cut approximately to the required length, are placed, preferably, one at a time in the proper position on the jointercarriage H snugly against the guard h and forced down upon the spurs h h, which hold them firmly in place. The carriage is then run past the revolving cutter-head I,which accuratelyjoints the adjacent edge of the section. The sections may be jointed, hollowing when desired, by adjusting the V-way h by means of the bolts h h", to curve outwardly at the center and thus produce a corresponding movement of the carriage. The joints may also be made open on the inner or under side of the head, thus insuring close joints outside by means of the adjusting-bolts h 71.", Figs. 3 and 4, whichelevate the way It and incline the carriage H with reference to the face of the jointerhead I. The sections are next placed upon the rests J J and forced edgewise against the (lowelingbits J J, which bore the holes for the dowel-pins. The spring h, compressed by advancing the sections upon the bits,forces The do wel-pins are now inserted, the sections glued and put together by the operatorinto blank heads, which are then placed upon the sawcarriage G snugly against the rack g, and gage g properly set for the required size and run past the saw F, which trims them to a uniform size, determined by the position of said gage g". The blanks are now placed one at a time on the rest-bars O O,and the gage-frame swung down upon them and secured to the forward end of the carriage A by turning the handle I), which forces one part of the cam B under the front rail of said carriage and the other part against the blank-head bearing at the opposite side at the front of the machine against the rear cross-rail of carriageA, as seen in Fig. 11, thus crowding the sections composing the blank snugly together and closing thejoints between them. The bolts 1) b, adjusted to bear the blank-head down to the desired level with reference to the cutting-line of the planer E, bring it into and hold the blank in the proper position while the operator forces the dogs cm into its edges, as seen in Fig. 12, by meansof the handle a and cam A operated thereby. The cam B is then turned to release theblankhead and gageframe B, which is automatically swung back by the spring 1) into the position shown in Figs. 2 and 4, where its backward movement is arrested by the projections b b striking the cross girt N. The lever L is then drawn back by the operator toward the front. of the machine, and, operating through the bell-crank lever L", carries the sliding rod L and belt'shifters Z Z to the right, as' seen in Fig. 1, shifting the straight belt shown in Fig. 3 from the loose pulley k to the tight pulley 7c, and through the bevelgears It, upright shaft K, pinion 7c and rack A, o eratin to feed the carria e b 0 forward. As it is carried over the cylinder E, the blank head is planed on its under side, and passing over the planer-bed IE it engages and forces the dogs 6* 6 down, and when it arrives over the lower clamping-head or round.
ing-table O, as seen in Fig. 4, the handle a of the cam A (thrown out over the side of the machine in dogging the blank-head in the carriage) strikes the adjacent bracket N, as seen in Fig. 4, and allows the dogs 0b a to be withdrawn by springs to a from the blank-head, which is forced off therefrom by the perforated plates D D and springs d d and deposited upon the rounding-table 0. As soon as the blankhead clears the dogs 6 6, they are forced up by the spring to which they are forged or attached and prevent the blank-head from being withdrawn by the returning carriage A, the front of which is raised, as shown in Figs. 3 and 4, to pass over the blank-head. The stop i striking the rod 1, projecting from the belt-shifting lever L, shifts the cross-belt from the loose to the tight pulley lc, and thus reverses the move ment of the carriage A, which returns to the the machine, the dog at engages the lever M,
as shown in Fig. 2, swings it forward into the position shownby dotted lines in the same figure against the stop m, and turning the rockshaft M and its crank M back into the position shown by dotted lines, Fig. 6, and, acting through the connecting-rod 'v' and arm 02, swings the cam V forward into the position shown in Fig 8. The front edge of the cam V, passing under the pin t, raises the tooth it into position to be engaged by a spur, a, on the side of the driving-gear U, as seen in Fig.
8. The mutilated gear T is thusturned sufficiently to bring its teethinto engagement with those of the driving-gear U, as seen in Fig. 9. The cam V standing quiescent while the blank, carriage remains at the front of the machine, the pin 25 slides off from the outer face of said cam and the tooth t is returned by the spring I? to its middle ornormal position, as seen in Fig. 7. The cam 0 driven by the gearT through the sprocket-wheels Q Q simultaneously with the cam 0 in the direction indicated by the arrow, Fig. 14, clears the friction-wheel 0 and lever O, and the weight 0 carries the upper clamping-head down upon the blank, as seen in Fig. 15. The points or spurs in the face of said clamping-head engaging the blank prevent the same from being turned or displaced by the rounding-heads. Both the clamping-heads O O, with the lever O and weight 0?, are now sustained by the cam 0 which rotates simultaneously and in the same direction with cam O, lifts the clamping-heads as the friction roller 0 traverses that portion of its periphery from 1 to 2, and elevates the blank into engagement with the upper rounding-head, S, as shown in Fig. 16, the saws s s rounding the head, and the knives s s chamfering it on the upper side or edge as the roller 0 traverses that part of said cam from 2 to 3. While the roller 0 traverses that part of the periphery of cam 0 from 3 to 4, which is concentric with shaft q, the barrel head is held in the same Vertical position, and the cam P, acting upon the upper roller, 19, lifts the bar P, carrying the wedge or cam-plate 1) under the roller 19* in drawbar 2)", moving the slide P" and the upper rounding-head secured theretolaterally to the right, as seen in Fig. 13, thus causing the cbamfering -knives s s and the vertical cutters s s to trim the head off on one side and make the same slightly oval, with its greatest diameter across the grain of the wood. This becomes necessary for tight barrels particularly, as in trussing and hooping the barrel the heads are considerably compressed across the grain of the wood, and if made perfectly round at the outset would be compressed to an oval form by trussing and hooping. As soon as the elevated portion of cam P passes the up per roller, the bar P is withdrawn to its middle position,the wedge-plate releases the roller p, and the slide P, with the roundinghead S, is forced back to its normal position against the stop 12 by the spring 11 The frie tion-roller 0, passing the point 4 and travers ing that portion of the periphery of cam 0 between 4 and 5, allows the clamping-heads, actuated by their own weight and the weighted lever O, to descend and carry the partiallyformed barrel-head into engagement with the lower rounding-head, R, as shown in Fig. 17, the cutters r 'rchamfering the barrel head on the lower side or edge. \Vhile the roller 0' traverses that part of the periphery of the cam 0? between the points 5 and 6, concentric with the axis of rotation, the barrel-head is sustained in the same vertical position,while the cam P forces the wedge-plate 19' down against the friction-roller p and moves the slide P and lower rounding-head sidewise, thus chamfering the lower side or edge of the barrelhead slightly oval to correspond with the upper (-ham fered edge, formed as previously de scribed.
The arms r r of the lower rounding-head, It, may be adjusted radially, so as to leave a square or vertical edge between the ehamfered or beveled faces, or so as to produce a sharp V-shaped edge. As the elevated portion of the cam P clears the lower frietiouroller, p, the bar P returns to its middle position, and the slide P is forced by the adjacent spring p back against its stop 10, as seen in Fig. 13. The cam 0, working with the friction-roller o froni 6 to 1, raises the rounding-table O to a level a little below the planer-bed E as seen in Fig. 3. Said frictionroller 0 then drops into a depression at 1 in said cam, as shown in Figs. 4 and 14. At the same time the elevated portion of cam O raises the clamping-head O sufficiently to allow the carriage A to pass under it with the next head, and the friction-roller 0 drops into a depression in the periphery of said cam, thereby arresting the movement of the clamping-heads and their actuatingcams, thatpart of the mutilated gear Tfree from teeth having returned to the starting-point adjacent to the gear U, as shown by dotted lines, Figs. and 7. The pin t of the sliding tooth t, arrlving at the rear edge of cam V, as shown by dotted lines, Fig. 9, passes under the shoulder thereof, as seen in Fig. 10, forcing said tooth down and straining the spring t, as shown by full lines, Fig. 5, and by dotted lines, Fig. 7. A11- other blank head having been placed and dogged in the carriage A, as previously described, the straight belt is shifted by the operator upon the tight pulley k by means of the lever L. As the carriage moves forward, the lever M is forced to follow it by the spring at (shown in Fig. 2) till it strikes the stop at, thus operating, through the rockshaft M, crank M and connecting-rod v, to throw the cam V back and release the pin 'L', which is moved by the spring it" into its middle position, (shown in Fig. 7,) to be raised by the next advance movement of said cam, as previously described.
The attachment of the draw-bars p 1)" to the slides P P may be so adjusted as to produce a greater or less sidewise movement to the rounding-heads and to make the heading more or less oval, as required, according to the material, it being necessary to make them more oval of soft material and less oval of hard wood. W'henever it is desired to run the blank-head back with the carriage A and plane both sides, or make two outs on a single side before depositing it upon the roundinghead 0, the handle a of the dogging-cam A is turned upon itsjoint (without turning the cam) so as to clear the standard N, and thus prevent releasing the blank at that point. The pin m being removed, the dog m Fig. 1, may
be turned in, so as not to engage the lever M on the return of the carriage and set the clamping-head and their cams in motion.
Various changes may be made in the details of construction, and the arrangement of the parts of my improved machine may be vari ously modified without departure from the spiritof my invention. To give the oval shape to the heading, a lateral movement may be given to the clamping-heads instead of the rotary cutters, and the rotary cutters may be moved vertically instead of the work.
