Definitions

  • This invention has reference to the manu-. facture by -machinery' of wooden barrelheads, or like disks, or articles-but forconvenienceof description itwillbe described as. -applied to themanufacture. of barrelheads.
  • The-operation on thebarrel-head to be performed in this-machine isthatof finishing off, 1 or particularly beveling.
  • the headstock. 4 enables the whole batch of heads to be pressed firmlyon to therotary bearings 1 0' of" the machine carri'erface. plate '1 below; an'das this face plate is revolved, the batch of heads is revolved-slowly by; the frictional contact between them.
  • a ball bearing. 3 is provided between thescrew 3, and the face-plate 21-to diminish friction: of the, bearing. of the 7 disk 2.
  • the face plate 1 also servesiasaicam which is adapted to operatethe cutter carrier. parts through levers orarms; namely, ⁇ theplate-1 is provided. with. a cam. shapedchannel 21 away from the axis of the plate 1, and move by means as hereinafter describedfthe- 'cutters toward and away fromthe'axis ofithe plate 1, and the barrelzheads toproduce a slightly I elliptical form: of head required, when such form is required-Y Th'isinward and outward; movement and thefrotation of the barrel heads,is a slow one.
  • Thelower enos ofthe: cuttercarrier. shafts 7, are each provided with fixed belt pulley 25, and the shafts 9 are fitted with a loosely mounted pulley 26; and the .drivingbelts 27 which drive the shaft 7 and cutters, pass from the pulleys 28 on the prime motion shaft 29, over the pulleys 26, which serve as guides to the belts 27 and keep the required tension on the portionswhich extend between 26 and 25, as the cutters are rocked about the shafts 9.
  • the cutters 6 are threaded on their spindles 7, and may be adjusted lengthwiseorr same by means of lock nuts or equivalent devices.
  • the reversing belt shifting gear 33 1s worked from a hand wheel device 35, and chain 36, and a sprocket wheel 37 supported in the bracket 38, the hub of which is a nut through which the threaded end of the shifter shaft 33 screws.
  • the cutter shafts 7 and their carrier arms 8 are moved up to and away from the barrel heads by a swivel nut 39 mounted in each of the lower arms 8see Fig. 3and a right and left hand threaded shaft 40 passing through these nuts, and operated by hand wheel 41 outside.
  • the shaft 40 is split at the center at 40*, and the two parts are coupled together by a sleeve coupling 44 and key and feather arrangement, so that when desired, viz., when making elllptical heads, the movement of the two parts of the shaft toward and away from each other, is permitted; and the two parts of the shaft 40 are connected to the cam levers 23 by links 42 connected to shackles 43 loosely mounted between collars on the shaft 40,- and thus these cam levers 23, are connected to the carrier arms 8, which are operated thereby.
  • the heads are to be circular, the cam channel 21 will be circular, and the cutters will only be moved toward and away from the edges of the head by rotating the shaft 40 by the hand wheel 41; but when the heads are to be elliptical, and an elliptical cam is used, the movement of the cut ters will be a compound one, viz., that produced by the cam by the means described, and that produced by the operation of the hand wheel 41;
  • the polygon marked 45 in Fig. 3 represents a head before it is out and trimmed, and it consists as shown of a center board 46, two end boards 47, and two intermediate boards 48, the center board 46 being sawn square across the ends, the intermediate parts 48 being sawn by an angle, and the edge boards 47 being also sawn at an an le; thus very little waste ismade.
  • the wood pieces 46, 47, and 48 should face plate above described, for adjusting or moving the cutters and their carrying arms is also an ellipse; but the difference between the lengths of the major and minor axes of the ellipse is quite smallsay about half an inch inmost cases.
  • the cutters will follow the ellipse form of the cam, but
  • the size of the ellipse will be regulated by the hand wheel 41.
  • the heads or ends revolve very slowly, and the two cutter carrying spindles revolve at a high speed; and by operating the hand wheel 41 the cutters are gradually brought on to the edges of the heads.
  • the cutters may be adapted to operate on both sides of the edges of the heads at once, or by different operations, so as to produce the beveled form of edge required;
  • the heads when placed in the machine, for being operated uponfwill have a small strip of wood say thick on opposite edges, so that they form distance pieces between the adjacent heads;
  • the cutters can be separated 1 from one another in the manner shown in the drawings.
  • the machine is suitable for making heads of dilferent sizes, and of different shapes as stated; and the cutter feed may be aut'oseries of barrel heads arranged in superimposed relation, upright shafts mounted beyond the support, spaced cutter carrying arms mounted on each of said shafts, a cutter shaft mounted in the free ends of each set of arms, an adjusting arm mounted for free rotary movement on each of the first mentioned shafts, a connection between each of sa1d ad usting arms, a cam way formed in the support, a screw shaft having threaded connection with each of said cutter carrying arms, means for connecting the ends of such shafts to permit the shafts to move longitudinally with respect to each other, and a connection between each of said shafts and the adjacent adjusting arm, whereby the cam way determines the cutting path of the cutters and the screw shafts the dimensions of such path.
  • a machine for shaping and dressing the peripheral edges of barrel heads comprising a rotary support formed in its under surface with a cam way, a clamping member mounted above the support and adjustable with relation to the support, said clamp member being mounted for free rotation to permit the clamping of a series of barrel heads between said support and clamping member, an upright shaft a cutter shaft mountedin the free ends of each pair of arms, an adjusting arm mounted for free rotation on each upright shaft and having a roller terminal to engage in said cam way, manual operable means connected to each of said adjusting arms for simultaneously adjusting the cutter supportingarms of the respective sets in relatively opposite directions.
