MACHINE FOR MAKING BARREL STAVES OR BLANKS- Specification of Letters Patent.

Patented Aug. 1,1905.

Application filed June 28, 1904 Serial No. 214,515.

To aZ whom it may concern:

Be it known that I, EUGENE E. BARTHOLO- MEW, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and useful Improvement in Ma-' means for forming in such veneer the croze and chime for the stave or blank.

The invention may be defined generally as consisting of the combinations of elements embodied in the claims hereto annexed.

' Referring to the drawings, Figure 1 represents a plan view of a portion of a veneer-cutting machine having my invention applied Fig. 2 represents an enlarged detail plan view showing the arrangement of the knives or tools which I employ. Fig. 3 is a view, partly in section and partly in elevation, showing the manner in which the tools are applied to the veneer material. Fig. 4: is a view in perspective of the croze-cutting knife or tool. Figs. 5 and 6 are respectively a perspectiveand a sectional view of a portionof a stave'or blank after the same has been operated upon by my machine.

In the manufacture of veneer barrels it is essential that the ends of the barrels be formed in such manner as to firmly retain the heads therein and at the same time not unduly weaken the material from which the barrels are made. Owing to the thinness of such material (veneer of about one-fourth inch being usually employed) it is difiicult to form a croze which will effectually retain the heads in the barrels and at the same time construct the chimes to sustain the strain incident to rolling and otherwise handling the barrels. I have found that the best manner to overcome these difliculties is to make the croze and chime substantially as shown in Figs. 5 and 6viz., by forming the croze as a continuous incline extending from near the end of the stave or blank a suitable distance to receive the head and terminating in an abrupt shoulder and by making the chime relatively short and of the entire thickness of the veneer. In order to form such croze and chime, I have devised the following construction.

In Fig. 1, 1 represents a part of the frame of a veneer-cutting machine, said frame supporting the dogs 2, by which the log 3 is sustained and rotated. Suitably supported in operative relation to the log is the knife 4, by means of which the veneer 5 is cut from the log. Opposite the knife 4 is the bed-plate 6, which carries the presser-bar 7 and tools 8,9, and 10, by means of which the croze is formed is trimmed. The veneer-cutting knife and the presser-bar, with the knives or tools 8, 9, and 10, are fed toward the log by means of 15 in the manner usual in veneer-cutting machines.

between the presser-bar 7 and the knife 4. The knives or tools 8, 9, andlO are positioned to act upon the material before it is removed from the log, thereby insuring a firm support for-such material.

The tools or knives are supported as follows: Olamped to the bed-plate 6 by means of bolts 16 is the clamping-plate 17, said plate having recesses 18 for the reception of the heads of the bolts 16, there being nuts 19 below the bed-plate for tightening said bolts. The presserbar 7 is inserted between the clamping-plate and the bed-plate and is held in place by tightening the nuts 19. The crozecutting knife or tool 9 is also inserted between said clamping-plate and bed-plate and is of the same thickness as the p'resser-bar, whereby the tightening of the nuts 19 also clamps said knife. The tools 8 and 10 are carried by tom face thereof a 'suflicie'nt distance to receive the appropriate tool between the upper wall of the recess and the clamping-plate 17 Bolts 22, having heads 23 engaging a T-shaped slot or keyway 24: in the clamping-plate, ex-

tend through the blocks 20 and 21 and are provided with nuts 25,'by means of which said blocks may be drawn toward the clampingplate and the tools 8 and 10 secured by clamping against said plate.

The tools 8 and 10 project toward the log and are above the knife or tool 9. The tool or knife ,9 is clamped adjacent to the presserin the veneer and the end of the blank or stave the shaft 11, gears 12 13 14:, and feed-screws:

The veneer as it is cut from the log passes blocks20 and 21, each of said blocks being. provided witha slot extending from the botbar 7 but is slightly separated therefrom a sufiicient distance to permit the insertion between said knife and bar of the point of the tool 8, as shown more particularly in Figs. 2 and 3. As will further appear from said figures, the point of the knife 8 projects slightly beyond the adjacent edge of the tool 9 and is at right angles tothe log 3, whereby said point cuts the abrupt shoulder 26 at the end of the incline 27 cut by the said tool 9. The knife or spud 10, which cuts ofi the surplus end of the stave or blank, is separated a short distance from the adjacent edge of thetool9 and projects beyond said tool and the knife 8, whereby it forms the chime 28. By simply slackening up the nuts 25the positions of the knives 8 and 10 may be varied either longitudinally or transversely of the clampingplate, as well as with reference to the tool 9.

The tool 9, as will appear from an inspection of Figs. 2, 3, and 4, is formed with an upturned lip 29, having an inclined edge 30, the inclination of such edge and" the adjustment of the knife being such as to enable it to cut the inclined croze 27. If preferred, the body of the tool may be wider than the cutting edge, as shown, providing a larger surface for engagement by the clampingplate 17.

From the foregoing it will be apparent that I have produced a construction which will not only enable me to simultaneously cut, croze, and chime veneer blanks or staves for barrels, but which will enable me to produce a form of croze and chime for such stave or blank which is peculiarly adapted for barrels made of thin material and which will permit the ready adjustment of the tools to meet varying conditions which may occur in the manufacture of such staves or blanks.

While I have described my invention in detail, it will be apparent that such details may be varied or departed from more or less without varying the spirit of my invention, and I do not propose to be limited to such details except as the same may be rendered necessary by the prior state of the art or may be embodied in the claims hereto annexed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
