MASON FOSHEE, OF CHAPMAN, ALABAMA.
BOLT-SAWING MACHINE.
SPECIFICATION forming part of Letters Patent No. 764,717, dated July 12, 1904.
Application filed April 30, 1904.
To all whom it may concern:
Be it known that I, MAsoN FosHEE, a citizen of the United States of America, and a resident of Chapman, in the county of Butler and State of Alabama, have invented certain new and useful Improvements in Bolt-Sawing Machines, of which the following' is a specilication.
My invention relates to bolters or slabslashers whereby the refuse of sawmills is cut so as to be utilized for diiferent purposes.
It is well known that in all sawmills there are great quantities of bolts, slabs, and other refuse from cutting lumber, which are generally used for fuel, and much of this refuse can be used when cut into proper leng'ths for staves, pickets, laths, posts, &c.
The main object of my invention is to provide an improved construction of bolt-sawing machine for this 'purpose in which the bolts, slabs, &c., are cut into desired lengths both economically and automatically and the machine can be so located as not to bein the way of other machinery, as are the ordinary bolt-sawing machines.
Another object of my invention is to provide a compact arrang'ement of parts whereby either a swinging band-saw or circular saw can be employed in connection with the means for raising' and lowering the saw-frame withthe saw and means for advancing theV material to be operated uponintermittently.
Another object of my invention is to arrange the swinging saw-frame transversely of the conveyer while the cam-wheel for moving the saw-frame vertically and the segmental gear-wheel for operating the conveying mechanism can be both located on the same powershaft at right angles and alongside of the sawframe.
To this end my invention comprises a conveyer for feeding the material to the saw, a transversely-arranged swinging saw-frame on which the saw is carried, having' a depending arm rigidly secured thereto, a power-shaft extending transversely of the conveyer, a`
cam-wheel having a rim formed with a flattened part and upon the periphery of which the saw-frame is supported by its depending Serial No. 205,649. (No model.)
arm, so as to be raised and lowered alternately, a wheel having a part of its rim provided with a peripheral segmental gear and fixed to the power-shaft, and a counter-shaft located parallel with the power-shaft, having a gear-wheel fixed thereto and moved intermittently by the engagement of the segmental gear with the gear-wheel, so as to drive the conveyer to feed the material beneath the saw, all as hereinafter described and claimed.
In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure I is a sido elevation of my improved. bolt-sawing machine in which I employ a band-saw, the latter being in operative position, and a chain-driven roller conveyer. Fig. II is a plan view thereof. Fig. III is a vertical transverse section thereof, taken on the line III III of Fig'. II looking in the direction ofthe arrows, the raised position of the saw-frame being' shown in dotted lines. Fig. IV is a side elevation of the segmental gearwheel for advancing the material intermittently. Fig. V is a side elevation of a camwheel for raising and lowering the saw out of and into position for work. Fig. VI is a detail view of the arm whereby the saw is supported on the cam-Wheel. Fig. VII is a side elevation of my machine in which I employ a circular saw-and the conveyer is` driven by a,
train of gear-wheels instead of a chain. Fig. VIII is a side elevation of my machine in which the material is conveyed to the saw upon a chain having flights. Fig. IX is a vertical transverse section taken on the line IX IX, Fig. VII, looking' in the direction of the arrows. Fig. X is a vertical transverse section taken on the line X X, Fig. VIII, looking in thedirection of the arrows.
l represents a suitable frame having standards 2, provided with bearings 3, in which is mounted a power-shaft 4, having' fixed thereto at one end a driving-pulley 5, driven by a belt 6. Fixed to the other end of the pulleyshaft L is an inner pulley 7.
8 is a transversely-arranged swinging bandsaw. frame loosely mounted at its inner end on the power-shaft 4 and embracing the inner pulley 7. Loosely mounted within the outer end of the saw-frame 8 is an outer pulley 9, and extending around both the inner and outer pulleys 7 and 9 is a band-saw 10, driven by theinner pulley 7 over the outer pulley 9.
11 represents depending guide-brackets secured to the lower edge of' the saw-frame for bringing the band-saw 10 into position for cutting the material in a vertical plane.
The saw-frame 8 is supported in part by a connterbalance-weight 12, suspended from a flexible connection 13, secured at its inner end to the sav-frame 8 and passing from the latter over a sheave 14, journaled in a hanger 15.
16 is a rear standard, and 17 a front standard, in which is mounted another power-shaft 18, having a driving-pulley 19, driven by a belt 20. Fixed to the inner end ofl this powershaf't 18 is a cam-wheel 21, having its rim formed with a flattened part 22, and fixed on the outer end ofl the power-shaft 18 is a wheel 23, having on the rim thereofl a peripheral segmental gear 24.
25 is a depending arm secured to the sawf'rame and having a bifurcated or forked lower end 26, in which is mounted an antifriction-roller 27, working on the periphery of the cam-wheel 21, whereby the saw-frame 8 is supported and lowered and raised alternately as the cam-wheel 21 is rotated to place the saw into and out ofl operative position.
28 represents paired series of supports f'or a conveyer for feeding' the material to the saw. Secured to these supports 28 are side walls 29, in which are journaled, alternately arranged, live rollers 30 and dead rollers 31, on which the material is fed to the saw 10.
32 is a counter-shaft journaled in asupport 28 at its inner end and in the front standard 17 over the power-shaft 18 at its outer end. Fixed to this counter-shaft 32 is a gear-wheel 33, intermittently rotated by the segmental gear 24 on the wheel 23 when the saw-frame 8 is raised from its working position.
On the journals of the live rollers 30 are mounted sprocket-wheels 34, which are engaged by a driving sprocket-chain 35, operated by a sprocket-wheel 36, fixed to the counter-shaft 32 at theinner side of the gearwheel 33.
The material when it has been cutis passed to a conveyer, comprising' supports 37, side walls 38, live rollers 39, journaled in the walls and having sprocket gear-wheels 40,whereby they are driven by a sprocket-chain 41.
42 represents dead rollers alternating with the live rollers 39..
Instead of the band-saw 10, (shown in Figs. I, II, and IIL) I may employ a circular saw 10, (shown in Figs.VII, VIII, IX, and X,) in which 8 is a saw-frame loosely mounted on a power-shaft 4fL between bearings 3 on standards 2. 5 is a driving-pulley fixed to one end of the power-shaft 4fL and driven by a belt 6, and 7 u is an inner pulley fixed to the power-shaft 4L adjacent to the saw-frame 8". Fixed to the shaft 10b of the circular saw 10 is an outer pulley 9", connected by a belt 7l with the inner pulley 7 for rotating the saw.
In Figs. VII and IX, I show the live rolls of' the conveyer driven by a train of' gearing 34a, and in Figs. VIII and X, I show a chain conveyer 30, having flights 31. The driving sprocket-chain 35 in this instance is led off under idle sprocket-wheels 35b beneath the receiving-conveyer. This is a convenient arrangement in connection with those sawmills which have one long continuous chain, as my sawing-machine can be installed by inserting a section of conveyer over the main conveyer, as shown in Fig. VIII.
rIhe operation of my improved sawing device will be readily apparent. The powershafts 4 and 18 of' the saw and feed-conveyer, respectively, being rotated in the direction indicated by the arrows and the cam-wheel 21 having its flattened part 22 uppermost and the wheel 23 having its peripheral segmental gear 34 lowermost, the saw is in its lowest operative position for cutting the material. As soon as the flattened part 22 of the cam-wheel 21 leaves the arm of' the saw-frame the latter is raised out of the path of the material. At the same time the cogless part of the wheel 23 passes from beneath the gear-wheel 33 and the peripheral segmental gear 24 advances and engages the gear-wheel 33, .thus rotating the counter-shaft 32 in the opposite direction to operate the conveyer and pull it the required distance to advance the bolt beyond the delivery side of the saw. Vhen the segmental gear 24 has passed beyond the gear-wheel 33, the conveyer is stopped, and as soon as the fiattened part 22`ofl the cam-wheel 21 reaches the depending arm 25 of the saw-frame the saw is lowered onto the bolt, which is quickly cut, and the receiving-conveyer removes the severed part. The distance the bolt is advanced is gaged by the comparative sizes of the gear-wheel 33 and sprocket-wheel 36 and the number of' cogs in the segmental gear 24.
It will be observed that the saw-frame IOO IIO
works up and down between the feeding and powershaft, a Counter -shaft, and a gearwheel fixed to the Counter-Shaft and rotated intermittently by the segmental gear and driving the Conveye-r to feed the bolts beneath the saw-frame.
Q. A bolt-sawing machine Comprising' a Conveyer, a transversely-arranged swinging Sawfranie having an arm provided with a roller, a power-shaft, a Cam-wheel lixed to the powershaft and upon the periphery of which the roller of the arm of the saw-frame is adapted to play to raise and lower the saw-frame, a wheel having a peripheral segmental gear and fixed to the power-shaft, a counter-shaft, and agearwheel fixed to the counter-shaft and rotated intermittently by the segmental gear and driving the conveyer to feed the bolts beneath the Saw-frame.
ygear-wheel fixed to the counter-shaft and rotated intermittently by the segmental gear and driving' the Conveyer to feed the bolts beneath the Saw-frame.
