sTAvE-GUTTING MACHINE.
SPECIFICATION forming part of Letters Patent N o. 271,290, dated January '30, 1883. Application tiled October 18, 188i?. (No model.)
To all whom it may concern:
Be it known lthat I, FRANZ WITZMANN, a citizen of the United States, residing at New Haven, in the county of New Haven 'and State of Connecticut, have invented a new and useful Machine for Cutting Staves, of which the i'olowing is a spccitication, reference being had to the accompanying drawings.
This invention relates to machines for cutting staves for barrels, tubs, and thelike; and it has for its objectto provide a simple and eftirient machine that can be readily adjusted to cut staves of varying length, width, thickness, diameter, or curve.
ln the drawings, Figure l is a side view of Fig. 2 is a front end View. Fig. 3 is a top view; Fig. 4, a detail sectional View of the cutting mechanism. Fig. 5 is a like view of the table and its elevating mechanism. Fig. 6 is a transverse sectional View thereof.
Referring to the drawings, A designates a fra me ofsuitable'construction, carryinga shaft, B, having crank-wheels C C, which are counected to the rock-arms D D-one at each side of the machineby pitman-rods E E. Arms I) D are arranged on a shaft, F, and carry a cross-head, G, working in theslot H iu each.
arm by means of an adjusting-screw, I, also working in said slot, by operating which the head may be moved either backwardly or forward] y. From head G extend brackets J through which Work screws K K to resistthe thrust of the knife, and also to aid in adjusting the same to elevate or lower said knife. The knife has its bearing surface on blocks L L at the ends of the cross-head, and are secured to said blocks by screws M, passing through the knife, block, and into the crosshead. The knife and blocks maybe readily removed by operating the screws for the substitution ofkuives and blocks ofvarying curves.
N is aguide arm or extension, against which the block from which the staves are cut will abut. One of these guides is secured at each end ot' the crosshead, and are longitudinally adjustable in relation to the machine by means of the screw-bolts O, working in slots P in said guides. The latter are curved and work through corresponding openings, Q, in the table R.
S is a curved spring, arranged back of the knife, and longitudinally adjustable in relation to the machine, either independently or by be- 4 ing secured to the adjustable guides N.
The table It has a transverse dovetailed groove, T, in which is placed a corresponding base-block, U, for the cutting-knife to strike, so as noty to dull its edge. This table is longitudinally adjustable on a bed, V, by means ofscrews W, working in slots X in the table It and into the bed V. This bed is? provided with longitudinal vertical side flanges, X X, for inclosing the table, and also with inclined guidesY on its under side and a vertical slot, Z, at its front. Guides Y work on corresponding inelined guides, A', projecting from a base-bed, B', which latter is also provided with a perforation, C', in its front.
D' is a hand-screw, workin g through perforation C' into a nut, E', arranged in slot Z, and adapted to move vertically therein. Thus by operating screw D' the bed V, carrying table R, may be elevated or lowered on the guides A'.
In lieu of guide-arms N N, suitable adjustable guide-blocks may be arranged on the table.
The boxes F' F', in which the shaft F works, are vertically adjustable by means of setscrews G", working against their under sides, which adjustment is effected to regulate the knife.
The operation and advantages of my invention will he readily understood. Motion is communicated to shaft B, and from thence transmitted by wheels C C and pitmen E E to rock the arms which carry the cross-head having the transverse curved cuttingknife. The block of wood from which the staves are to be cut is slid under the knife against the guides before the downstroke of the knife, which will cut off the stave, after which the block is fed against the guides, ready for the next stroke ofthe knife. 'Ihe staves, after they are cut, pass up back of the knife, and are held by the springs until the stave is pushed out over the cross-head by the next newly-cut stave.
This machine is very simple and convenient, and will operate to cut the staves as fast as the block can be fed under the knife.
I claim as newl. In astave-cutting machine, the cross-head carrying a transverse curved cutter, and a spring in rear ofsaid cutter to retain the last cross-head and projecting up back of the knife,
as and for the purpose set forth.
3. The combination, with the cross-head having the brackets projecting from the top, of the curved-face front removable blocks and the curved transverse knife secured to the latter, and provided with screw-threaded shanks working up in said brackets, as set forth.
4. The combination of the frame carrying the drive-shaft, crank-Wheels, and pitmen, the
- longitudinally-adjustable table, the rock-arms jonrnaledon a transverse shaft in rear of the table, and provided Withlongitudinal slots, the cross-head adjustable by means of screws in these slots, and carrying front blocks, and the knife secured to the latter, as set forth.
the inclined upwardly-'projecting guides and front perforation, the upper bed having corresponding downwardly-projecting guides andA front slot, in which vertically slides a nut, and the hand-screw for operating the beds, as set forth. l
In testimony that I claim the foregoing as my own l have hereto affixed my signaturein presence of two Witnesses.
FRANZ WITZMANN.
