Description
UNITED STATES PATENT OFFICE.
GEORGE C. BARNES, OF BATTLE CREEK, MICHIGAN.
IMPROVEMENT 1N SAW-MILLS.
Specification forming part of Letters Patent No. 33,425, dated October 8, 1861.
To all whom t may concern.-
Be it known that I, GEORGE O. BARNES, of Battle Creek, in the county of Calhoun and State of Michigan, haveinvented certain new and useful Improvements 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 accompanying drawings, and Lto the letters of reference marked thereon.
In the annexed drawings, making part of this specification, A represents the frame or bed of the mill, upon which the machinery is constructed.
B representsa frame which is hinged upon the bed A in such a manner that one end may be made to rise and fall, when desired.
O O represent the journal-boxes in which the journals of the frame B play. These journals are hollow, n and passing through them is a shaft D, which is used as the feed-shaft of the mill. A band from this shaft passes around the mandrel-shaft, so that when the frame B is raised or its position is changed the feed-shaft will always stand in the same relative position to the mandrel.
E represents a shaft which lies across the frame or bed A and under the frame B. This shaft has two arms ct, which press against the under side of the frame B. It also has an arm b, to which a connecting-rod cis attached. d represents a lever, one end of which is secured to the connecting-rod c, and by means of which said connecting-rod operates upon the arm h, the shaft E, the arms d, and thence operates the frame B. When the lever d is moved in one direction, the frameB is raised, and when moved in the opposite direction said frame is lowered.
F is the saw-mandrel which lies across the frame B, and which has its bearings in it, and of course when the frame is raised the saw is raised with it, being secured to the mandrel. The object of this frame B is to raise the saw to the log, so that the log may be properly slabbed by the passage of the saw through it once.
Figure 3 represents the position the saw would stand in were it not raised to cut through the log.
The dotted lines in Fig. 2 represent the position the saw would stand in when the frame B was raised or partially so.
I-'I represents the head-block on which the log is placed. Slidingin grooves in this block H are two bars K K, which have an upright L secured to each near its end. I is the log, and J J the dogs which secure the login place. In order that the log may be brought up close to the saw and sawed up entirely, I leave a projection oc upon the bar K beyond the upright L, as seen in Fig. et, upon which projection the log rests until entirely sawed up. This is an inportant feature, for without it several inches of the log are left unsawed, while withit the last inch of log may be saWed.
Having thus fully described my invention, I claim- The employment of the adjustable frame B with saw-mandrel secured in it, with the feed-shaft D passing through the hollow journals of said frame B, arranged and operating as and for the purpose herein specified.
" In witness that I claim the foregoing I have hereunto set my hand in the presence of witmesses.
GEORGE C. BARNES. Witnesses:
A. LAEEVER, J. N. MOORE.
