ATTACHMENT FOR WOODWORKING-IVIACHIN ES.
SPECIFICATION forming part of Letters Patent No. 788,434, dated April 25', 1905.
Application filed May 10, 1904. Serial No. 207,273.
To (LZZ whom it may concern;
Be it known that I, DARIUS W. SHOLLEN- BERGER, a citizen of the United States, residing at Montgomery, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Attachments for I/Voodworking-Wlachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in a resawing mechanism, and it is especially adapted foruse in connection with moldingmachines, matching-machines, and surfacing or sawing machines.
The invention consists in an attachment for woodworking-machines comprising a vertically-adjustable member, a swinging adjustable member, and a laterally-adjustable member, the said members carrying and controlling one or more saws.
The invention further consists in a vertically-adjustable plate capable of attachment to a woodworking-machine, a pivotally-moving plate carried thereon, and a laterallymoving yoke mounted on the plate having a sliding action, together with a cutter-arbor and one or more cutters carried thereby.
The invention also consists in certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter more fully described and claimed.
In the accompanying drawings, Figure 1 is 'an end elevation of the frame of a woodworking-machine, my improved sawing mechanism being secured thereto and shown in elevation. Fig. 2 is an edge elevation of the said sawing mechanism. Fig. 3 is atop plan view of a portion of a woodworking-machine, showing the resawing mechanism mounted thereon. Fig. 4 is a horizontal sectional view Fig. 5 is a detail sectional view taken longitudinally through the saw-bracket and plate holding the same, the section being taken longitudinally of said bracket and the saw arbor being shown in elevation. Fig. 6 is an enlarged detail view of a saw held in position for resawing flooring. Fig. 7 is a similar view, but
showing the saw held at an angle and in readiness for resawing moldings.
The present invention is designed for providing a simple and easily-adapted mechanism for the resawing of moldings, flooring, wainscoting, siding, or ceilings of various patterns to produce duplicates at a single operation of the machine. The attachment is capable of being mounted upon molding-machines, matching machines, surfacing machines, or various kinds of sawing-machines.
In the accompanying drawings I have illustrated the invention as applied to a bed or frame of a woodworking machine, the attachment being carried by a depending apron 1, secured to the work-bed 2 at one end thereof. The apron 1 is so formed as to adj ustably support the resawing mechanism, and in order to hold the same in proper position-when adjusted the apron is formed in its outer face with a vertical groove or recess 3. Movably mounted upon the apron 1 is a vertically-adjustable plate 4, which is formed with a rearwardly-projecting rib or tongue 5, which fits into said groove 3. A simple means of adjusting the plate 4 upon the apron 1 is illustrated in the drawings and consists in a vertically-arranged screw 6, which is carried at its lower end by an inturned lug 7, formed at the lower end of the plate 4. The screw 6 engages, a screw-threaded aperture formed in a rearwardly-projecting lug 8. The lug 8 is carried by the apron 1 and is of course held in a fixed position. By rotating the screw 6 by means of the hand-wheel 9 the plate 4 may be raised or lowered with respect to the apron. The extent of movement of the plate with respect to the apron can be accurately discerned by means of a scale 10, formed upon the edge of the apron l, and a pointer 11, carried by the plate 4. If it is desired to raise the plate 4 a half-inch or an inch, it is only necessary to turn the screw 6 until the pointer 11 shows the desired lifting of the plate with respect to the scale 10. The adjustment of the plate 4 forms the means for attaining the dilferent heights desired for the resawing-cutter.
It is often necessary to set the cutter of the resawing mechanism at various angles with respect to the work-bed 2 and its guide 12,
which is mounted thereon. The face of the guide 12 stands perpendicular to the top surface of the work-bed 2. In order to secure the desired angles, the saw-carrying mechanism is so mounted upon the outer face of the plate 4: that it may be moved upon the are of a circle the center of which lies in the intersection of the plan of the guide with the upper surface of the work-bed. With this point as a center a segmental groove 13 is formed, the said groove being adapted to receive a corresponding segmental rib or projection 14:, carried upon the back of a plate 15. The groove 13 is also provided with a segmental slot 16, which extends through the material of the plate 4, and bolts or screws 17, secured to the said plate 15, engage the said slot 16, so as to prevent the segmental rib from being accidentally displaced. These bolts are suificiently loose to permit of the adjustment of the plate with respect to a vertically-adjustable plate 4: beneath it. To render the adjustment of the plate 15 easy of accomplishment, a screw-rod 18 is employed, one end of which has a bearing in a swivel-stud 19, carried by a projection upon the plate 1, while the other end, which is screw-threaded, engages a swivel-nut 20, carried in a bifurcated portion 21 of the plate 15. The screw-rod 18 is also provided with a hand-wheel 22, by which it may be easily and quickly rotated in changing the angle of the plate 15. To properly gage the angle of said plate, a segmental scale 23 is placed upon the plate 4: adjacent to the segmental groove 13.
The cutter employed is preferably a saw 24, secured to an arbor 25, which arbor is provided with an actuating-pulley 26. The arbor is mounted in bearings 27 and 28, which are secured to the bracket 29. The engagement of the arbor with the bearings is such that the arbor may be rotated, but cannot move longitudinally with respect to the bracket. The arbor is so mounted upon the bracket that the saw can be brought in alinement with the angle formed by the guide 12 with the surface of the bed 2, as shown in Figs. 1 and 7. In order to be able to adjust the arbor laterally upon the swinging plate 15, the bracket is movably held thereon by means of bolts 30 and 31, which engage slots formed transversely of the plate 15. In order to prevent the bracket from assuming different angles with respect to the plate 15 and yet to permit the same to be adjustable across the plate 15, the plate is provided with a transverse groove 32, which is engaged by the transverse projection or rib 33, formed upon the back of the bracket 29. The bracket is formed with an apertured lug 34 opposite the groove 32, which is engaged by the threaded rod 35, so that by turning the rod the bracket may be moved back and forth with respect to the plate 15. The screw-rod 35 is held in proper position by its engagement with the bearing formed in astandard 36, which is turned outwardly from the face of the plate 15. A hand-wheel 37 is secured to the end of the screw-rod 35 to rotate the same. The screw 35 is arranged parallel with the groove 32, so that in turning the screw the bracket is moved so that its rib or guiding projection 33 may move back and forth in the said groove. In this manner a lateral adjustment of the resawing-cutter can be efiected. The various adjustments of the plates and the bracket, as above described, are independent of each other, so that one adjustment can be made without affecting another. The pulley 26 is adjustably fixed to the arbor 25, so that it may be secured at any point along the length thereof to adapt it to connection by means of belting with any suitable power mechanism.
In using the resawing mechanism for forming molding the saw is preferably set at such an angle that it will divide the molding evenly,
forming duplicate pieces upon each side of the saw. A saw is brought to such a position that it will cut in a plane intersecting the angle made by the guide 12 with the bed-plate 2, as clearly shown in Figs. 1 and 7. If, however, the saw is to be employed for resawing flooring, the plate 15 is so adjusted as to bring the arbor 25 in a vertical plane. The plate 4: is then elevated upon the face of the apron, so that the saw is lifted to a plane parallel with the surface of the bed 2 and in proper relation to split the flooring, as shown in Fig. 6. The adjustment of the saw vertically is operated with reference to the scale 10, so that the cut in resawing can be made accurately at the point desired. The adjustment of the saw at the different angles for operating upon diiferent materials is quickly effected by rotating the screw-rod 18 and moving the bracket-supporting plate 15 upon the arc of a circle with reference to the scale 23.
In order to keep the parts which have been sawed by the cutter a suitable distance from each other and to prevent the upper piece from dropping and resting upon the saw, I provide a plate or arm 38 at a point opposite the edge of the saw, the said plate being mounted upon the end of the arm 39, which is secured to the arbor-bracket 29.
It will be observed that the resawing attachmenie is of such a character that it may be readily applied to various kinds of woodworking-machines, and mechanism is simple and easily operated and yet very effective for the purpose desired. It is possessed of advantage also in that the various movements of the parts to their adjusted positions may be independent of each ither.
From the fact that the arc of a circle upon which the angular adjustments of the saw are obtained has for its center the point at the intersection of the guide with the working bed it follows that the saw or cutter may be set to any desired angle with respect either to the guide or the bed-plate. After the angle desired has thus been obtained a horizontal adj ustment as well as a vertical adjustment may be effected without disturbing the angle with relation to the bed-plate and the guide. It will be evident that the saw or cutter may be set to any vertical distance from the face of the bed-plate and then changed to any required angle, after which it may be adjusted horizontally without disturbing the obtained vertical distance with relation to the bedplate. It will also be evident that the saw may be set to any horizontal position in relation to the guide, and then the angle of the saw may be altered to a proper position in relation to said guide and bed, or any desired vertical position may be obtained in regard to the bed and the angle with respect thereto afterward obtained, the cutting-line of the saw always retaining its relation to the center of the arc of the circle on which the angular adjustment is made. The center of the arc of the circle located at the intersection of the guide and the face of the bed-plate is not lost by any vertical, horizontal, or angular adjustment which may be made.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. A resawing mechanism comprising a vertically-movable support, a pivotally-mounted support carried thereon, a laterally-moving bracket upon the pivoted support and a saw carried by the said bracket, the pivotal mounting of the pivotal support being such that the center of movement for said pivoted support shall lie in the plane of the cut made by the saw.
