UNITED STATES PATENT OFFICE;
GEORGE J. KAUTZ, OF EMPORIUM, PENNSYLVANIA.
IMPROVEMENT IN CIRCULAR SAWING M ACHINES.
Specification forming part of Letters Patent No. 198,025, dated December 11, 1877; application filed September 14, 1877.
To all whom it may concern:
Be it known that I, GEORGE J. KAUTZ, of Emporium, county of Cameron, and State of Pennsylvania, have invented a new and Improved Oircular Sawing Machine, of which the following is a specification:
In the accompanying drawings, Figure 1 represents a sectional side elevation of my improved machine; and Figs. 2 and 3 are vertical transverse sections of the same, respectively on lines 00 w and y y, Fig. 1.
Similar letters of reference indicate corresponding parts.
This invention relates to an improved sawin g-machine for cutting lumber to any required length in quick and regular manner, and is an improvement upon Letters Patent No. 189,628,
, granted to meApril 17, 187 7 5 and theinvention consists of a feed mechanism for the lumber, constructed of a weighted top roller and lower spiked roller, in connection with an intermittently-revolving spiked feed-roller, and of a revolving circular saw, turning in an inter-' mittently-swinging frame. A lever arrangement throws the feed mechanism and saw in or out of gear by a suitable clutch device with the driving-shaft, and regulates the cutting off of the lumber.
In the drawings, A represents the support ing-frame of my sawing-machine, at the upper part of which a'guideway, B, for the lumber,
and a table in front of the same is arranged. At the end of the way B is the feed mechanism, which consists of an intermittently-revolving spiked roller, 0, that turns in end bearings of way B, and serves to feed the lumber forward in quicker or slower manner, according to the speed of its rotation next, of a second spiked roller, 0, that turns in bearings of a forked vertically-sliding standard, G and, lastly, of a weighted top roller, D, that turns in a'frame, D, pivoted to a fixed standard of the way B. The roller-frame D is also fulcrumed to a vertically-sliding leverrod, a,that is pivoted at the lower end to a fulcrumed lever, b, which engages by its opposite lug b of the standardC. The lever-rod a is further engaged by a fulcrumed lever, d, that is operated by a lever-rod, d, extendlng above the top of frame A, so as to raise, by depressing lever-rod d,-the top pressure-roller I),
and simultaneously lower, by lever b, the stand spring, e, of the standard G throws the same 7 upward, and causes thelowering of the press ure-roller D and the firm holding of the lumber between the pressureand spiked rollers. The lower end of the standard 0 isalsobifurcatedand curve-shaped, so as to engage the collar of a clutch device, f, of the driving-shaft, and throw the clutch in or out of gear with the same.
Simultaneously with the taking hold of the lumber by the feed mechanism, the clutch is thrown into gear with the driving-shaft, and thereby not only, by belt-and'pulley connection, a circular saw, E, revolved at the upper end of a swinging frame, E, but also a cogwheel, f, engaged by a pinion of the clutch. The cog-Wheel f engages, by side extensions of its teeth, a pinion, g, and pushes, by a segmental cam, g, of the cog-wheel, the pinionshaft forward to clutch a cone-pulley at the other end, which, by a connecting-belt and cone-pulley of the shaft of the spiked front roller 0, imparts intermittently-revolving motion to the same, so as to feed the lumber for ward for the next cut of the saw.
The spiked roller of the spring-acted standard and the pressure-roller hold-the lumber firmly to the cutting action of the saw, while the spiked front roller, in connection with the rollers, moves the lumber at different speed forward, according to the position of the belt on the cone-pulleys and the length of lumber required. The circular saw E swings across the end of the guideway of the lumber, for cuttin'g'off the same, the swinging motion being imparted to frame E, that turns on the driving-shaft by a cam-groove, h, at the opposite side of the cog-Wheel f, the cam-groove engaging a pin, h, at the lower part or heel of the swinging frame, and causing the same to move forward at the proper time for cutting off the lumber and passing quickly back before the forward motion of the lumber commences. As soon as the clutch is thrown out of gear, the working of the machine is interrupted and the lumber-holding rollers raised, so as to discontinue instantly the operation of the machine whenever required.
The forward feeding of the lumber takes quickly place after each cutting action of the saw, and cuts up the lumber into pieces of a certain length in a rapid and effective manner.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a sawing-machine, the combination of a lumber holding and feeding mechanism, consisting of an intermittently-revolving spiked front roller, a vertically-movable spiked roller, and a top pressure-roller with a revolving and intermittently-oscillated circular saw, substantially in the manner described, and for the purpose specified.
2. The combination of the lever arrangement with swinging pressure-roller, spiked bottom roller, and vertically and spring acted standards, to release or hold lumber, as-required, substantially as described.
3. The combinationof the operating-lever arrangement with the lumber feeding and holding mechanism, and with clutch device of driving-shaft, the latter operating spiked front rollers and circular saw to throw machine in or out of work, substantially as specified.
4. The combination of clutch device of driving-shaft, having intermeshing pinion, and of a cog-wheel having segmental cam at one side and cam-groove at opposite side, with transmitting pinion and gear of spiked front roller,
and with swinging frame of circular saw, to.
