SAWING-MACHINE.,-
SPECIFICATION forming part of Letters latent N0. 630,1 18, dated August 1, 1899.
Application filed April 6,1899. Serial No. 711,939. (No model.)
To all whom it ntag concern.-
Be it known that we, GOTTLIEB EMIL SoHLE- GELMILCH and FRIEDRICH ALEXANDER MANN, mechanical engineers, subjects of .the
. Emperor of Germany, residing at Suhl, in the Empire of Germany, have invented certain new and useful Improvements in Sawing- Machines, of which the following is a clear description.
[O This invention relates to sawing-machines, and especially to sawing-machines designed to work upon metal; and it consists in the improved sawing-machine substantiallyas will be hereinafter pointed out and finally x 5 embodied in the clauses of the claim.
It is a leading object of the invention to I provide a revoluble disk saw-blade having a circular central opening, in the edge of which the cutting-teeth shall be formed, and
7 to journal this saw-blade in the end of a lever, which shallbe automatically actuatedto advance the saw through the material being operated upon. By disposing the cuttingteeth about a central opening in the blade 2 5 it is not only possible to readily remove the parts when necessary, but without weakening the blade and thereby causing it to either tremble or buckle while being used, or even fracture, it may be constructed considerably o thinner than a blade having its cutting-teeth upon its perimeter. Furthermore, owing to this disposition of the cutting-teeth of the blade it is possible to out very thin and comparatively weak metal tubes without the liability them through the action of the saw.
Our invention is fully illustrated in the accompanying drawings, wherein- Figure 1 is a top plan View of the sawingmachine. Fig. 2 is a View in side elevation of said sawing-machine, and Fig. 3 shows a certain weight employed in connection with our machine. I
The frame of the machine consists of a bedplate a, at one end of which projects upwardly a pedestal b. The upper end of said pedestal is provided with a hearing I) for a shaft 6 which carries at one of its ends a drive-wheel e and at the other of its ends a sprocket-wheel g and a securing-nut e for holding the parts in position.
of. bending or otherwise damaging c designates a pair of blocks having openings in which the material to be cut is adapted to be placed, being securely held in position by screws 0', Working in said blocks and provided with handles 0 of well-known construction.
Upon the shaft e is fulcrumed a lever f.
In the outer end of this lever is journaled with its axis of rotation parallel to the shaft e the rim of a sprocket-wheel h, aplate h being secured by screws upon the face of said rim opposite to that adjoining the sprocket-wheel to hold the rim in its bearings in the lever. 6 7c is a circular saw-blade having a central opening, the edge of .which is provided with cutting-teeth 7c.
Power is transmitted from the one to the other of the sprocket-wheels by a chain In order to efiect an automatic feeding of the saw-blade through the material to be cut, a flexible connection, which is secured to the free end of the lever at f and is controlled by weights p, carried upon a hooked bolt 0, having a nut 0, upon which latter the weights rest, is provided, said flexible connection passing over a suitable roller m, journaled in the bed-plate, and over a pair of rollers 'n, suitably journaled in some other stationary part. By varying the number of weights the action of the lever f, and consequently of the saw, in working its way through the material being operated upon can be readily adjusted.
It may be remarkedthat in order to render the saw-blades interchangeable they may be removably secured upon that face of the sprocket-wheel rim which adjoins the teeth of the latter by means of screws.
Having thus fully described our invention, What we claim as new, and desire to secure by Letters Patent, is I v 1. In a sawing-machine, the combination of a suitable frame, a lever fulcrumed in said frame, a circular saw journaled in said lever, means for rotating said saw and means for efiecting movement of said lever about its fulcrum synchronously with the sawing operation, substantially as described. it
2. In a sawing-machine, the combination of a suitable frame, ashaft journaled in said frame, a lever fulcrumed on said shaft, a circular saw journaled in said lover, a chain and sprocket connection between said saw and the shaft, and means for efiecting movement of said lever about its fulcrum synchronously with the sawing operation, substantially as described.
3. In a sawing-machine, the combination of a. suitable frame, a shaft jour'naled in said frame, a lever fulcrumed on said shaft, a. circular saw journaled in said lever and havinga central opening, the teeth of said saw being formed in the edge of the opening, a chain and sprocket connection between said saw and the shaft, and means for elfectingmovement of said lever about its fulcrum synchronously with the sawing operation, substantially as described.
4. In a sawing-machine, the combination of a suitable frame, a shaft journaled on said frame, a lever fulcrumed on said shaft, a cir cular saw journaled in said lever and having a central opening, the teeth of said saw being I formed in thaedge of the opening, a chain and sprocket connection between said saw and the shaft, suitably-disposed rollers, a flexible connection passing over said rollers and secured at one of its ends to the lever,
and a weight or weights securedto the other end thereof, substantially as described.
In testimony that we claim the foregoing we have hereto set our-hands this 18th day of March, 1899.
