' IMPROVED. METHOD OF REGULATING THE VELOCITY 0F FEED Foa SAWlNG-MlL'LS.
Specification forming partof Letters Patent No. 15,559, dated August 19, 1856.
To all w/wm it'may concern: 1
' Beitknown that I, R. EIoK'nMEYnRpf Yonk ers, in the county of \Vestchester and State of New York, hzwe invented a new and use ful Improvement in Saw-Mills; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a. part of this specification, in which- Figure 1 is a vertical section'ot' my improvement, :0 00, Fig. 2, showing the plane of section. Fig. 2 is also a vertical section of the same, yy, Fig. 1, showing the plane of section; Figs. 3 and 4 is a view of the devices by which a movement of varying speed is given the shaft which drives the carriage. Fig. 5 is a detached view of the expanding pulley.
Similar letters of reference indicate correspon ding parts in the several figures,
My invention consists in connecting the crankshaft which drives the saw with the shaft which drives the carriage in such a manner that a variable speed is'given the car riage, so that the log may be properly fed to the saw and the feed made to suit either a vertical or inclined saw, as will be hereinafter fully shown and described,
To enable those skilled in the art to fully understand mid-construct my invention, I will proceed to describe it. v
A represents a frame constructed in any proper manner to support the working parts.
B represents a shaft, which is. attached to the upper part of the frame A. On the shaft -B an expanding pulley, C, is placed loosely, theshaft being stationary and the pulley r0- tating upon it. This pulley is formed of two circular plates or disks, to a, connected by oblique" rods 0, the ends of the rods being jointed to the inner sides of the plates or disks a a, as shown clearly in Figs. 2 and 5. The outer plate or disk It is placed loosely on a sliding collar, 0, on the shaft 13, and a horizontal lever, D, is connected to the collar 0. An upright lever, E, is connected to the horizontal lever D. The inner plate or disk at is attached permanently to a collar, d, on the shaft B, said collar having a pinion, F, which gears into a rack on the under side of the carriage on which the log is placed. A belt, e, passes around the pulley 0, said belt also passing around a shaft, G, which is placed in the lower part of the frame A. An idle or friction roller, f, whichis placed in a swinging frame, H, bears against thebelt e.
It represents the crank shaft from which the reciprocating saw is driven. Th1s shaft has a pinion, f, upon it, which vpinion gears into a corresponding pinion, g, on a shaft, I. The shafts I and G are placed out of line wlth each other, and to thesinner end of the shaft G, at its periphery, there is attached a pin, h, which pin fits in a grooved plate, i, attached radially to the inner end of the shaft I. This is clearly shown in Fig. 3. It will be seen that when the shaft H is rotated a variable motion will be communicated to the shaft G, for when the pin it is at the inner end of the grooved plate '6 the motion of the shaft G will be considerably slower than when the pin h is at the out-er end of said plate, and the shaft G,
therefore, will rotate about half of a revolution quicker thanthe other half. By this means the carriage is operated quicker at one time than at another, and the log is fed to the saw in a proper manner. For instance, if .a
verticalreciprocating saw isused, the log must be fed to the saw as the saw descends, arid the crank on the shaft H must be so placed that the most rapid motion will be given the car" riage as the saw descends,- the log being fed to the saw as it cuts; b ntif an inclined or raking saw is used the crank is so placed that the carriage will be moved more rapidly as the saw ascends.
Instead of the pin hand grooved plate 2', a draw-link, j, may be used, as shown in Fig. 4. The same effect is obtained by either device.
By operating the lever E the diameter of the pulley C may be increased or diminished, as occasion requires, the rods'b allowing the two disks or plates a (t to approaeh and .recedefrom each other. By this means the speed of thecarriage may be increased or diminished, as desired.
Having thus described my iuventiomwhat I claimtas new, and desire to secure by Letters Patent, i's- "Driving 0]: operating the log -earr1age by means of two shafts, I G, placed more or less out of line with each other and connected by a pin, h, and grooved plat'ez' or draw-link j, or any equivalent device, for the purpose of giving a variable movement to the carriage, thereby feedingt-he log to the saw, as described. t
