BARREL-STAVE-CUTTIHG MACHINE Application filed (letober 12, 15321.

To all whom it easy canoe r Be it known that we, ERA D. STAROHER and CF innns Youne, citizens of the United States, residin at Swandale, in the 5 county of Clay and State of l lest Virginia,

l inven certain new and useful linhave proveinenn. in l3arrel-Stave-Cutting Mamade imitormly, so that the stoves will 'n'operly and all barrels made O'i the number of staves, will be of a uniforr i aineter in L'YOSS section, well as being of a uniform shape.

Another purpose is the provision oi a maeh'ine which will cut staves of any width by operating a hand-wheel which causes the to be adjr either inwardly or outinahe either narrow or Wide staves, purpose is the provision oi I eluding a be above the carwhich the stave is guided, in romwith a spri g 'lfQDSlOll-Bk'l stave err protruding above the bed, to ing the stave in position while through the machine and thereby e stave to the proper shape. urtlier purpose is the provision of coml U and spring means for returnm the carriage to its initial position, it being obvious that either the gravity or the s 'iring means may be dispensed. with it desired.

still further purpose is the provision oi a machine of this design wherein opposed circular saws are employed for cutting the oppos te edges of the stave, the carriages of the saws being operatively connected with the ed carriage below the bed, so that when the 36d carriage is o erated longitudinally oi the frame of the machine, the saw sup porting carriages will move toward and from each other, whereby the opposite edges of he stave are given arcuate contours, so that when a series or" stares are put together, they will "form the usual shape of a barrel.

Serial No. 507,320.

The invention additionally aims to provide means for adjusting the saw supporting carriages toward and from each other, in order to vary the width of the stave.

he invention also aims to provide a bed inclutnng rollers for the barrel staves, and superimposed opposite rollers bearing upon the staves during their passage between the rollers, to hold and guide them while being rut,

d hile the design and construction at present illustrated and set forth are deemed pieterable, it is obvious that as a result of a reduction or the invention to a more practit l form for commercial purposes, the invention may be susceptible of changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further features and roinbination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a view in side elevation of the proved barrel stave cutting machine connoted in accordance with the invention;

Figure 2 is a vertical longitudinal seetional view tl'irough the same;

Figure 3 is a plan vi w;

l igiu'e l is a sectional view on line 4-4 of Figure 1;

Figure 5 is a transverse sertional view on line 5-5 of Figure 2;

Figure 6 is a sectional view online 6*6 oi"? Figure 1, looking upwardly in the direo tion of the arrow, thereby showing the various parts of the machine in bottom plan; and

Figure 7 is a detail view 0t one or the pulleys 73.

Referring to the drawings, 1 designates the frame, which may be of any suitable shape or construction, preferably rectangular as shown. The upper part of the frame comprises a bed consisting of the side rails 2 and the intermediate bed rails 3, and mounted in bearings 4 and 5 of the side and intermediate rails are shafts G, on which stars bed rollers 7 are mounted to rotate therei'ith. These rollers are interposed between the intermediate rails 3 oil the bed, and are designed to support the stave as it is being cut, Preferably the bed has eight rollers, though it is obvious thatany num ber of rollers may be employed, preferably four in front and four to the rear. At corresponding number of opposed stave holding rollers 8 are superimposed relatively to the rollers 7, and are mounted upon the shafts 9. These shaft-s 9 are mounted in bearings of the links 10, which are pivotally mounted upon the shafts 11, as shown clearly in Figures 1, 2 and 3. The shafts 11 are mounted in bearings 12, which rise from the longitudinal side rails 2. The

shafts 9 have sprockets 13, which are conthe sprocket chains 21, which operatively gear with the sprockets 22, which are mounted upon the shafts It will be noted that one of the shafts 6 is in two sections 6, which are axially aligned, and have their adjacent ends separated to permit the passage of a stave engaging claw An additional sprocket 24 is carried by one of the shafts 6, adjacent the feed end-of the machine, said sprocket being engaged by a sprocket chain 25. Une end of one of the sections 6 of one of. the shafts 6 has an additional sprocket 26, about which a sprocket chain 2? travels. The corresponding end of the opposite section 6 has a sprocket 28 engaged by a sprocket chain 29, which engages about a sprocket 30 on the shaft 6 which is adjacent the far discharge end of the machine. Mounted in bearings of the lower longitudinal side rails 31 of the frame is a drive shaft .32 carrying a pulley 33, to which any suitable power (not shown) may be belted. Also mounted uponv the drive shaft 32 are sprockets 84 and 35. Also mounted in bearings of the lower side rails 31 of the frame are stub shafts 36, which carry sprockets 37, engaged by the sprocket chains 38. The sprocket chains engage about thesprockets 34 and 35, so that power may be transmitted from the drive shaft to the stub shafts 36, and since the chains and 27 engage about the sprockets 39 which are also mounted upon the stub shafts 36, power is transmitted to one ofthe shafts 6 and one of the shaft sections '6. Obviously since the shafts 6 and the shaft sec5ions 6 are co nec ed as pre viously described, power is nsinitted to the bed rollers, and from the bed rollers to the stave holding rollers 8, in order to feed the staves. through the machine.

Obviously the bed rollers and the stave 65 holding rollers may be rubber covered shown) or otherwise provided with feeding surfaces (not shown) in order to insure feeding the stave through the machine,

A channel guide 40 is mounted upon the lower end rails 41 of the frame, the channel of which is T-shaped in cross section, and receives a correspondingly shaped carriage 43, the lower surface of which has suitable rack teeth 44, which are engaged by the teeth of the gear 45, which is mounted-upon a shaft 46 in bearings 47 of the channel guide. This shaft is also mountedin bearings of one of the longitudinal side rails the frame, and surrounding the shaft is a coil spring 48, one end of which is attached at 49 to the frame of the machine, while the other end is attached at 50 to the shaft, so that when the carriage 48 is moved forward, the spring 48 will tend to turn the shaft and gear 45 in the direction to return the carriage to its initial position.

It will be noted that the carriage 48 elongated, and carried thereby are two parallel strips 51 which are provided with a plurality of apertures or openings 52. A pin 53 is designed to engage through any two registering openings or apertures 52, and through the stave engaging claw 23,. order to pivotally and adjustably mount the claw on the carriage 43. This claw 28 engages and operates betweenthe innermost of the frame, is

intermediate rails 0 provided with a serrated claw shoulder 54, which normally protrudes upwardly'beyond the upper surface of the top railsof the frame, in order to be engaged by the state 55 to be cut. The claw 23 has aforward cam edge 56, which, as the rarriage reaches the limit of its movement, and cams upon the shaft 6 adjacent the discharge end of the frame,thereby camming the claw downwardly against the action of its leaf spring 57, and thereby disengaging the shoulder 54 from the end of the stave. Gbviously the claw may be adjusted to accommodate barrel staves of different lengths. i The end portions of the carriage are provided with transversely disposed uide rails 58, on which the saw carriage mov' plates 59 are guided. These carria e moving plates have arcuate slots 66, in which the feet 61 of the saw carriages are movable. In other words the saw carriage operating plates 59 are movable longitudinally of the frame, and since the slots 60 arcuate in contour, the feet are giv slight rocking movement in a horizor al plane. The feet 61 are secured by col to the depending legs 63, which caiifod by the saw carriages 64, which areinovalile laterally toward and from each other guides 64. In fact the upper parts 0). legs 63 have cylindrical portions 65, which will rotatably engage correspondingly shaped openings 66 of the saw carriages 1 0 shafts 8a and 85.

Beyond the cylindrical portions 65, the legs 63 have extensions 67 rectangular in cross section, which engage correspondingly shaped openings 68 in the bases of the mandrel holding blocks 69. It will be noted that the legs 63 are movable rockably relatively to the saw carriages 64, and are movable with the bases of the mandrel holding blocks 69; therefore when the feet and legs 61 and 63 rock according to the shape of the arouate slots 60, the mandrel holding blocks 69 will correspondingly move, so that the circular saws may twist in a plane horizontally. Mandrels 70 are mounted in bearings 71 of the mandrel holding blocks 69 and carry circular saws 72. it will be noted that the mandrels 70 are inclined downwardly and laterally from each other, so as to hold the circular saws at angles converging downwardly and toward each other. By this arrangement the saws act to bevel the stave, so that the stave may fit and engage with adjacent staves, in forming the barrel.

The mandrels carry pulleys 73, which are engaged by the round belts 74, which pass over the idlers 7 5, and also engage the groove pulleys 76, which are mounted upon the.

drive shaft 32, therefore it will be noted that when power is transmitted to the shaft 32, motion is imparted to the mandrels 70, thereby rotating the circular saws. A suitable guard 7'? is provided, so as to protect the operators hands from the teeth of the saws. Also mounted upon the bases of the mandrel supporting blocks 69 are suitable guides or guards 7 8, which are provided for the purpose of preventing excessive vibrations of the saws.

The rectangular extensions 67 receive transversely disposed pins 79, which are positioned above the bases of the mandrel supporting blocks, and thereby act to prevent downward movements of the legs.

It will be noted that the plates 59 are Inmalj-le transversely of the machine, and since they are guided upon the guides 58 which are carried by the carriage 43, the plates 59 are held in their relative positions. However, the lower face of the plates 59 have grooves 80, which are engaged by the lugs 81 of the racks 82, which in turn mesh with the gears 83, mounted upon the shafts 84: and 85. The far end of the machine has a transverse shaft 86 mounted in bearings 87, and carried by the shaft 86 are beveled gears 88, which mesh with the bevel. gears 89 carried upon the One end of the shaft has a hand wheel 90. by which motion may be imparted to the shaft 85, and through the medium of the shaft 86, motion is imparted to the shaft 84;. By this arrangement it is obvious that the plates 59 may be adjusted toward and from each other, and in so doing, the saw carriages 6e may likewise be adjust ed, thereby positioning the circular saws closer together or farther apart, for the pur pose of making wide or narrow staves, according to the size of barrel to be constructed. The gears 83, are mounted between the bearings 91, in which the shafts 8a and 85 are mounted.

Each of the plates 59 comprises a body section 92 and a clamping section 93, which is detachably secured by bolts 9% to the bod; section, whereby the clamping section may be detached, for the purpose of grinding its faces 95, so as to position the arcuate face 96 of the clamping section closer to the opposite arcuate face of the slot 69. in other words the opposite arcuate faces of slots .30 in time become worn, and in order to compensate for the wear, the clamping sections 93 may be detached, so that the faces 95 of the clamping sections 93 and the corresponding faces engaged by the faces 95 may be grounded or machined, so that when the clamping sections 93 are reconnected to the body sections, the slots 69 are made narrower, sufficient to properly receive the feet 61.

in the operation, the piece from which a stave is to be cut is placed so as to pass between the rollers S and the rollers 7, that the end of the piece may engage the claw shoulder 54:, and then the pressure is applied to the piece or strip 55, pushing the claw 23 forward and with it the carriage a3, and since the plates 59 are operatively connected to the carriage ell-5, the plates 59 correspoudingly move, and since the slots 66 are of arcuate contour, rocking movements are imparted to the feet and the legs 61 and 63, thereby correspondingly rocking the mandrel carrying blocks 69. @bviously the saws 72 will rock in horizontal planes, according to the shape of the arcuate slots 60. and will thereby cut a stave of proper shape, to cooperate with similar staves, when forming a barrel. It will be noted that the saws 72 converge downwardly and toward each other, and owing to this arrangement the opposite longitudinal edges of the stave are beveled simultaneously with the arcuate shape given to said edges, so that when the staves are arranged in position to form a barrel, they will properly fit, in order to render the barrel of circular contour in cross section.

vlVhen the stave has finished its travel through the machine, and the teeth of the saws have completed their work, the inclined cam edge 56 contacts with the shaft 6 adj acent the forward portion of the frame of the machine, which will cause the claw 23 to earn downwardly against the action of the leaf spring 57. As soon as the stave disengages from the claw shoulder 5% the claw may return to its initial position under the action of the spring 57. At the same time that the claw is returned to its initial position, the carriage s3 is returned to its normal position, through the medium of the spring and the. weight 97, which is attached to a suitable cable or rope 98, which in turn is connected at 100 to the carriage 43. The cable or rope 98 passes over a pulley 101, which may be mounted in any suitable manner upon a stationary structure (not shown) to the rear of the machine.

Coil springs 102 surround the shafts 11. l ne end of each coil spring 102 is attached at 108 to one of the arms 10, while its other end is attached at 104- to the diametrically opposite arm 10. The construction and arrangement of these springs 102 are such as .,o exert pressure on the arms, so as to hold the rollers 8 upon and in contact with the stave or the piece from which the stave is cut, during its passage through the machine.

The grooves in the pulleys 73 and 7 6 are melatively deep and wide,and their flanges flare outwardly. In other words the walls of the grooves flare outwardly, particularly those of the pulleys T3, as shown in Figure round belts 74 from so as to prevent the slipping off.
