PHILIP S. REYMAN, OF MOUNT CARMEL, ILLINOIS, ASSIGNOR TO JOHN C. KELCH, OF MOUNT CARMEL, ILLINOIS.

STAVE-JOINTING MECHANISM.

To all whom 'it may concern:

Be it known that I, PHILIP S. REYMAN, a citizen of the United States, and a resident of Mount Carmel, in the county of l/Vabash and State of Illinois, have invented a new and Improved Stave-Jointing Mechanism, of which the following is a full, clear, and exact description.

My invention relates to stave jointing mechanism, my more particular purpose being to improve the means used for cutting the edges of staves in order to give such edges the proper conformity to enable them to it against the adjoining edges of other staves, so that when the staves are assembled they will fit each other neatly and the barrel or other receptacle made from them will have, if desired, a suitable bilge.

More particularly stated, my stave jointing mechanism comprises a plurality of rotary saws mounted independently and adapted to swing in planes crossing the general direction of rotation of the saws, and variable form pieces to be used in connec- ,tion with these saws for guiding the latter in shaping the staves.

My invention further comprehends mechanism associated with the saws and form pieces above mentioned, for the purpose of swinging said saws in said plane crossing the direction of rotation, and also means for enabling the operator to move at will, relatively to the saws, the form pieces and staves resting thereupon.

My invention comprehends also various mechanical features for improving the general eiciency of stave jointing machines and devices relating to the same.

Reference is to be had to the accompanying drawings forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a central fragmentary plan view of the device, showing the saws and two-part form pieces and mechanism immediately associated with said saws and form pieces; Fig. 2 is a vertical Asection taken substantially on the line 2-2 of Fig. 1, looking in the direction of the arrow and showing the worm gearing used for swinging the saws in a direction lateral to the general plane of rotation of said saws; Fig. 3 is a substantially centralvertical section upon the line 3 3 of Fig. 2, looking in the direction of Specication of Letters Patent.

the arrow, and showing how one of the saws acconnnodatcs itself to the conditions required in cutting a stave; and Fig. 4 is a fragmentary section on the line 4-4 of Fig. 3, looking in the direction of the arrow, and showing how the form pieces are slidably mounted.

Mounted upon pedestals 5, 6 are bearings 7 8, and journaled within these bearings is a horizontal shaft 9. Journaled upon a portion of this shaft is a bearing sleeve 10. A worm sector 11 is, by aid of a key 12, connected rigidly with the shaft 9. Another worm sector 13 is connected by a key 14 with the bearing sleeve 10.

Two worms 15, 16 are geared together by aid of pinions 17, 18 and are disposed partially within an oil basin 19 which is integral with the pedestal 5. Adjacent to the worms 15, 16 are bearings 20 through which extend two parallel horizontal shafts 2l, 22, upon which the worms are mounted rigidly. A hand wheel 23 is used for turning the shaft 22 and thus communicates motion to the worms and sectors.

The worm sectors 11, 13 are provided respectively with portions 24, 25 extending obliquely upward, and are further provided with bearings 26, 27. Extending through these bearings and supported thereby are horizontal shafts 28, 29. Above the bearing 26 the upwardly extending portion, 24 is provided with a fork 30. Upon the opposite side of the machine is a similar fork 31 integral with the upper portion of the sector 13, Pulleys 32, 33 are supported by the forks 30, 31. For this purpose I provide each of these pulleys with a shaft 34, as indicated in Fig. 2.

For the purpose of supporting these two shafts and the pulleys 32, 33, I provide bearings 35, 3G, 37, 38, the bearings being disposed at the tops of the forks 30, 31. Two revoluble saws 39, 40 are supported by the forks 30, 31, and disposed intermediate these saws at the lower portions thereof are two form pieces 41, 42, of the shape indicated. Each of these form pieces at its upper surface has a general arcuate form, the form pieces thus being higher in the middle than at the ends thereof. Each form piece is also thicker at its middle than at its ends, as will be understood from Fig. 1.

The two form pieces 41, 42 are provided at their ends with lugs 43, 44 and with stop plates 45, 46 for a purpose hereinafter described. The` form pieces 41, 42 are also provided with bearings 47, 48, 49, 50 whereby they are sustained. These bearings encircle the horizontal rods 28, 29. Mounted upon these bearings are guides 51, 52, 53, 54 arranged in pairs as indicated in Figs. 1 and 4. rhese guides enable the form pieces 41, 42 to swing toward or from each other, carrying with them the rods 28, 29 and yet holding the various parts in proper working relation. Mounted upon each fork 30, 31 are brackets 55, 56, and journaled upon these brackets are levers 57, 58 carrying presser wheels 59, 60 and weights (51, 62.

At 63 (Fig. 3) is shown a stave which is being cut. The horizontal rod 28 is supported at its ends by brackets 28a, 28h, se-

cured thereto by keys 28, 28d, the horizontal rod 29 being supported somewhat similarly by brackets 29a, 29h, the bracket 29a, however, being free to turn upon the shaft 9 while the bracket 29b is keyed at 29I2 rigidly upon the bearing sleeve 10. The horizontal rods 28, 29 are adapted to approach and recede from each other, and in doing this the saws 39, 40 are similarly moved toward and from each other; the angle between the general planes occupied by the saws being changed with the degree of rotation in a plane crossing the general plane of rotation of the saws.

The operator, by turning the hand wheel 23 back and forth, causes the worms 15, 16 to turn, the rotation of one of these worms being always contrary to the rotation of the other. rIhe worm sectors 11, 13 are thus turned in opposite directions in obedience to the control of the hand wheel 23. As the worm sectors 11, 13 thus turn in opposite directions, the horizontal rods 28, 29 ap.- proach and recede from each other, the saws 39, 40 being thus under control of the operator.

rEhe operation of my device is as follows: The operator, by turning the hand wheel 23, b-rings the form pieces 41, 42 into proper relation for cutting stave joints, I will say, for some particular purpose. rEhe carriage, including the form pieces 41, 42, is moved to the right according to Fig. 3j The presser wheels 59, G0 are now raised slightly by lifting the weights 61, 62 and a stave blank 63 is inserted in the machine. This is done by pushing one end of the stave blank down against the lugs 43, 44. The downward pressure of the weights 6l, 62 causes the presser wheels 59, 60 to hold the stave blank firmly, but yieldingly, in position. During all this time the saws have rotary motion. The stave blank having' been adjusted as described, the carriage is moved to the left according to Fig. 3. rlhe saws engage the adjacent end of the stave blank and cut operated upon.

through it, the inclination of the saws relatively to each other controlling the inclination of the cut edges of the blank. As the carriage travels to the left, the action of the presser wheels 59, 60. is such as to gradually rock the blank as indicated in Fig. 3. That is to say, as the carriage moves along, the presser wheels 59, 60 following generally the contour of the upper surface of the form pieces, cause the blank 63 to'constantly shift its position, the end of the blank at the left gradually rising and the opposite end being gradually lowered. The presser wheels being stationary in regard to the general position of the saws necessarily engage the stave blank at points immediately adjacent to the saw teeth, that is, those particular teeth which at any instant happen to be cutting. The pressure is preferably applied just a little in frontof these teeth, as will be understood from Fig. 3. The blank, while constantly changing its position, is at each moment. pressed hard upon the form pieces, the pressure being exerted at the exact point where it will do the most good in holding the stave blank steady as the latter is being There is thus little or no tendency of the rotating saws to displace the stave blank, the operating pressure of the saw teeth being so distributed relatively to the pressure exerted by the presser wheels 59, 60, that the operation of the saw tends to prevent, rather than to permit, the stave blank to be dislodged or otherwise disturbed. The pressure of the presser wheels 59, 60 has, it will be observed, a close relation to the pressure exerted by the saw teethv uponk the stave blank in the act of cutting the same. The degree of curvature. given to the form pieces 41, 42 must necessarily tend to control the shape of the barrel or other member for which the stave is being prepared. Not only can the curvature of the bilge be controlled perfectly, but the diarne-` ter of the prospective barrel can also be controlled by aid of this apparatus.

The parts are so arranged that the aXis common to the shaft 9 and the bearing sleeve 10, represents the geomet-ric axis of the prospective barrel or other member to be made up out ofthe staves thus prepared. Moreover, the form pieces together constitute a divided form whereby the machine is easily adjusted to various widths of staves.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: f'

1. In a stave jointi-ng mechanism, the combination of a form made in a plurality of parts movable relatively to each other, a plurality of saws, one disposed adjacent to each of said parts for the purpose of cutting opposite edges of a stave blank resting upon said form, means controllable at will for moving one of said parts and one of said" saws bodily in relation to another of said parts and another of said saws, and a presser member associated with one of said saws and movable therewith for the purpose of pressing upon the stave blank at a point adjacent to said last-mentioned saw.
