W OOD-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 589,793, dated September '7, 1897.

Application filed April 22, 1897. Serial No. 633,383, (No model.)

To an whom it may concern:

Be it known that we, Lnwrs S. Pnocron and FREDRECK Nnunonrn, citizens of the United States, residing at Sheffield, in the county of Colbert and State of Alabama, have invented new and useful Improvements in lVood-Sawing Machines, of which the following is a specification.

This invention relates to wood-sawing machines having two gangs of saws which rotate, respectively, in horizontal and vertical planes; and the chief objects of our invention are to provide a new and improved woodsawing machine of the character referred to wherein the gangs of saws are conveniently adjusted and perfect control is obtained of the feed-rollers which feed the lumber or timber to the saws for the purpose of sawing it horizontally and vertically at one operation in the manufacture of butchers skewers, blin'dslats, laths, chair-rounds, and other articles of woodwork where comparatively small pieces of predetermined dimensions are desired.

The object of ourinvention is accomplished in the manner and. by the means hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1 is an elevation looking at what may be termed the left-hand side of our improved wood-sawing machine. Fig. 2 is a similar view looking at the right-hand side of the machine. Fig. 3 is a broken or sectional top plan view of the same, and Fig. 4 is a front end elevation. i

In order to enable those skilled in the art to make and use our invention, we will now describe the same in. detail, referring to the drawings, wherein it will be observed that the main frame of the machine, as here shown, comprises posts or uprights 1, horizontal beams 2, connecting the upper ends of the posts or uprights, and similar beams 3, connecting the lower end portions of the same. The horizontal beams 2 support a work-table l, having suitable openings 5,in which lower feed-rollersl'i are journaled in any suitable manner. The work-table 4: is provided with a vertical worlcguide 7, adapted to be adjusted laterally and to be securedin its adjusted position through the medium of setbolts 8 or any other devices suitable for the purpose. The gang of saws 9, which rotate in a vertical plane, are suitably spaced apart upon an arbor 10, which is journaled in the upper end portion of an inclined yoke-shaped frame 12, having its lower end portion pivoted to the main frame, as at 13, in such manner that the frame can be raised 'or lowered to vertically adjust the gang of saws 9. The gang of saws 14, which rotate in a horizontal plane, are suitably spaced apart upon a perpendicular arbor 15, mounted in suitable bearings upon a laterallymovable frame 16, having its rear en ti pivoted to the main frame, as at 17, in such manner that the frame can be swung laterally in the arc of a circle in much the same way that the yoke-shaped frame is swung vertically in the arc of a circle. The vertical arbor 1-5 is provided with a pulley 18, adapted to be driven by a belt connection with the shafting, which serves to impart motion to the main driving-pulley 19. (Best seen in Fig.

The lower feed-rollers 6 cooperate with upper feed-rollers '20, which are journaled in snitablebearings upon a vertically-adjustable frame composed of a horizontal member or portion 21 and perpendicular limbs 22, which extend down through. the main frame of the machine and are provided near their lower ends with lateral pins 23, entering slots in the horizontal arms 24 of bell-crank levers 25. The bell-crank levers are composed in the present instance of rock-shafts provided with the lever-

arms

24 and 26, as will be clearly understood by reference to Fig. 3. The vertical arms 26 of the rear bell-crank levers are pivotally connected with the vertical arms of the front bell-crank levers through the medium of horizontal rod 27, and the front bell-crank levers 26 are pivot-ally connected by a link 28 with a yoke 29, the arms or members of which are pivotally engaged with toggle-levers 30, jointed together, as at 31, and pivoted, respectively, to the frame of the machine, as at 32, and to the'upper front end portion of the pivoted yokeshaped frame 12. The yoke 29 has a swiv' eled connection with one end of a horizontal screw-shaft 33, working in a rocking screwnut 34:, journaled in suitable bearings on the main frame, as best seen in Fig. The outer end of the screw-shaft 33 is provided with a hand-wheel or handle 35, by which the shaft can be rotated in either direction for the purpose of operating the toggle-levers 30 to raise or lower the yoke-shaped frame 12 and the frame 21, whereby the saws 9 and feed-rollers are simultaneously raised or lowered.

In Fig. 1 the yoke-shaped frame 12 is at the limit of its upward motion and the vertical saws are in their highest position, while the upper and lower feed-rollers 6 and 20 are in position to operate upon the lumber or timber to "feed the same through the machine. As shown in Fig. 1, the toggle-levers are in alinement perpendicularly, and obviously if the hand-wheel be turned in the proper direction or to the right the toggle-levers will be thrown out of alincment, the joint 31 will move toward the hand-wheel, and the vertical saws 9 and feed-rollers 20 will be lowered. Conversely, if the hand-wheel 35 be turned in the opposite direction or to the left the yoke 29 will be moved rearward, the ends of the toggle-levers which are jointed together will partake of the motion of the yoke, and the saws 9 and feed-rollers 20will be raised. The vertical motion of the feed-rollers is effected by the link connection 28 with the front bellcrank lever 26, the rod connection 27 between the bell-crank levers, and the loose connection of the bell-crank levers with the limbs 22 of the frame 21, in which the feed-rollers 20 are j ournaled.

The front end of the laterally-swinging frame 16, which carries the horizontal saws 14, is pivotally connected with one of two toggle-levers 36, jointed together, as at 37, the other toggle-lever being rigidly secured to a vertical shaft 38, Fig. 3, on which is mounted a bevel-gear 30, meshing into a pinion on the inner end of a horizontal shaft 41. This shaft 11 is provided at its outer end with a hand-wheel or other suitable handle 42, by which the shaft can be rotated in either direction. As shown in Fig. 3, the toggle-levers 36 are in alinement and the gang of saws 14: is at the limit of its inward motion toward the yoke-shaped frame 12. If the handwheel 42 be turned in the proper direction, the beveled gear 39 and shaft 38 are turned and cause the toggle-levers 36 to be thrown out of alinement, thereby drawing or pulling the front end of the pivoted frame 16 laterally toward the right-hand side of the machine for the purpose of adjusting the horizontal saws relatively to the vertical saws. The horizontal saws are located immediately in rear of the vertical saws and the saws of each gang are spaced at any required distance apart through the medium of spacing blocks or washers in such manner that the saws of each gang may be adjusted relatively to one another to suit the conditions required. The frame 12, which carries the vertical saws, is provided with a series of attached splitters 43, which serve to separate the pieces which are severed by the vertical saws. The frame 16, which carries the horizontal saws, is also provided with a series of splitters it, between which the strips divided by the horizontal saws pass and by which the strips are held separated. spectively, in unison with the pivoted frames 12 and 16, so that they are adjusted in harmony with the adjustment of the gangs of saws.

The lower end of the vertical saw-arbor 15 is preferably supported by an adjustable step-hearing 45.

The rear end of the main frame is provided with bearings in which a shaft 46 is jour naled, which shaft is provided with an attached belt-pulley 17, having a belt connection 48 with a pulley 40 on the arbor 10 of the vertical saws. The shaft 46 carries the main driving-pulley l9 and is provided at one end with a pulley 50, connected by a belt 51 with a pulley 52 on a shaft 53, journaled in suitable bearings at the front end portion of the machine. The shaft 53 also carries a pulley 54, which is connected by a belt 55 with a'pulley 56, secured to a stud-shaft 57, provided with a comparatively small pulley 58. The rear end of the main frame is provided with a bearing 59, in which is pivoted, as at 60, a bellcrank lever comprising a long arm 61 and a short arm 62. The long arm 61 is provided with an adjustable weight 63 and the short arm is provided with a belttightening pulley 64c, engaging an endless belt 65, which passes around pulleys on the lower feed-rollers 6, pulleys 011 the upper feed-rollers 20, and around the pulley 58. The rocking bell-crank lever 61 serves to hold the endless belt 65 under tension, but at the same time permits the frame which carries the upper feed-rollers 20 to be raised or lowered, as occasion may demand.

The belt 51, which serves to impart motion to the feed-rollers of the machine, can be tightened and loosened through the medium of a belt-tightener 66, mounted on the short arm 67 of a hand-lever 68, pivoted intermediate its extremities, as at 69,'to the righthand side of the main frame. By operating the hand-lever 68 the belt 51 can be tightened or loosened and the operation of the feed-rollers be thereby regulated for the purpose of controlling the feed of the lumber or timber.

The laterally-adjustable side gage 7 can be adjusted relatively to the saws, and it constitutes a guide for the lumber or timber passed through the machine. The vertical saws act to divide the lumber or timber verticallyinto pieces or strips, and the horizontal saws subdivide such pieces or strips into a plurality of stripssuch, for example, as are useful in the manufacture of butchers skewers, blind-slats, laths, chair-rounds, or any other pieces which require to be of predetermined dimensions.

The mechanism described for vertically adjusting the yoke-shaped frame 12 renders it possible to cause the vertical saws to cut at any required height, and the laterallyswinging frame 16 enables the horizontal saws The splitters and 44: move, re-

lOO

to be adjusted, so that they may be made to out any desired distance into the lumber or timber. It is also possible to draw or pull the frame 16 late ally away from the vertical saws such distance that the gang of vertical saws may be used simply as ripping-saws. By spacing the vertical and horizontal saws the required distance apart the lumber or timber can be cut into any size required by one passage through the machine, whereby resawing is avoided. It is also possible to remove all except one saw and to use this saw for rabbeting purposes.

The splitters a3 and 4i keep the sawed pieces in proper position and preserve the mass of lumber or timber in proper form while passing through the machine. It will be observed that the splitters and the upper feedrollers move in unison with the saws and thus simplify the practical use of the machine for cutting the lumber or timber into pieces of any desired dimensions at one operation.

The belt for operating the feed-rollers is preferably in the form of a chain belt engaging chain-wheels on the shafts of the feedrollers.

In our improved wood-sawing machine the vertical saws and the upper feed-rollers are adjustable in unison, and the positive rotation of the feed-rollers is under perfect control of the attendant through the medium of the hand-lever 68.

While the improved machine is useful for many purposes, it is particularly designed for sawing timber into comparatively small pieces of predetermined dimensions, as before stated.
