N. F. STONE, OF ATHENS, ILLINOIS.
IMPROVEMENT IN MACHINES FOR GUMMING SAWS.
Specification forming part of Letters Patent No. 37,014, dated November 25, 1862.
To all whom it may concern.-
Be it known that I, N. F. STONE, of Athens, in the county of Menard and State of Illinois, have invented a new and Improved Device for Gumming Saws; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a front elevation of my invention. Fig. 2 is a side sectional view of the same, taken in the line as m, Fig. 1. Fig. 3 is a section of a portion of the same; Fig. 4, a horizontal section of the same, taken in the line z 2, Fig. 1, and looking upward.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to an improved sawgumming device of that class in which rotary cutters are employed; and it consists in a novel construction and arrangement of the parts, as hereinafter fully shown and de scribed, whereby it is believed that a more simple and efficient device is obtained than those hitherto used for the purpose, and one capable of being more readily manipulated and applied to its work.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A represents what may be termed the stock of the machine or device, which is of cast metal and composed of two cheekpieces, a a, one of which, a, has a shank, b, provided with a nut, 0, at its lower end, through which a screw, B, passes, the screw being parallel with the shank, as shown clearly in Fig. 2. Between the two cheek-pieces a a a space, (I, is allowed to receive the saw, (shown in red, Fig. 2;) and O is a setscrew, which passes laterally through the cheek-piece a, for the purpose of securing the device to the saw. At the upper end of each cheekpiece a a there is an arm, 6, which projects horizontally forward. These arms 6 have each a pin or guide, f, projecting from it at right angles. At the lower part of the stock A, below the junction of the cheek-pieces, there is an arm, g, which projects horizontally forward, and has a pin or guide, it, extending from it at right angles, as shown clearly in Fig. 4.
D is a frame, which is fitted between the front sides of the cheek-pieces a a and between the guides ff h h, and is allowed to work freely up and down between the cheekpieces and guides. The upper end of the screw B is connected to the lower end of the frame D, and is allowed to turn freely in it, and by turning said screw the frame D, it will be seen, may be raised and lowered.
E is a shaft, which passes horizontally through the frame D, and has a cutter, F, upon it, such as are commonly termed burrs, and are formed by having a series of teeth on a cylinder. (See Figs. 1 and 2.) The bearings it of the shaft E are fitted in recesses j j in the frame D, and are retained therein by caps k k, which work in contact with the front sides of the cheek-pieces a a, as shown more particularly in Fig. 5. The caps k may be of leather, wholly or in part, and they form the only points of contact between the frame D and the cheek-pieces a a. By this arrangement the bearings of the shaft E are retained in proper position and the shaft prevented from having any play which would have a tendency to cause the cutters to work unevenly and not produce smooth or clean cuts.
The device is used as follows: The operator stands behind the saw and secures the device to it on its front or toothed edge, the saw being in the space d, and the screw 0 turned so as to clamp the device to the saw. The shaft E is then turned by means of a crank, E, and the screw B is also turned. The cutter F acts upon the tooth of the saw, commencing, if necessary, at its extreme point, the cutter be ing fed or moved to its work by turning the screw B. (See Fig. 2.)
The device as a whole is extremely simple and efficient, may be constructed at a small cost, and without the liability of getting out of repair or having any parts deranged by use.
I do not claim, broadly, a rotary cutter placed in a sliding or adjustable frame, for that device has been previously used for gumming saws; but
I do claim as new and desire to secure by Letters Patent 1. The stock A, formed of the two cheekpieces a a, set-screw O, and shank b, in combination with the frame D, provided with the frame-work within the guides f f h'h,formed at the ends of arms 6 e 9, connected with the upper and lower ends of the cheek-pieces, as and for the purpose set forth.
