Description
OLIVER B. JUDD, OF ROGKTON, NEW YORK.
SAWMILL.
Specification of Letters Patent No.
. carriage head and tail-block with my improvement attached to the tail block. To construct the same, I make two wedge shaped pieces of-wood (A, A,) about five feet long six inches thick about twenty inches wide at i one end and running to a point. I bevel the the shaft tail block (Fig. 2) on the under side at each end fitted to the wedges (A A) in such a manner as will leave the tail block i (Fig. 2) level. `In the upper edge of these wedges (A, A,) I place a cast iron rack with cogs (B, 13,) nearly the whole length of the wedges (AA) except that part lying under the tail block (Fig. 2). On the back edge of the said tail block I place a shaft of iron (C) with two pinions (D7 1),) secured by i boxes (EEP) to the'said tail block (Fig. 2)
and the pinions are so placed on said shaft as to fit in the cogs (B. B). In the center of (C) are holes to receive the point `of the mill bar by which the shaft (C) is 8,757', dated February 24, 1852.
rolled and carries the wedges (A A) by means of the rack and pinions under the tail block (Fig. 2) and raising it to any distance required according to the size of the log to be sawed. n
The object of my improvement is to raise the end of the log that lies on the tail block sufficiently high so that when the saw commences cutting at the head block with the bottom of the saw and finish at the tail block with the top teeth of the saw, thereby enabling the `operator to use the whole cutting edge of the saw the log and keeping the edge of the saw every time it cuts through.
straight by use, instead of jointing and filing the teeth that do not cut except in very large logs, also a saw of any length may be used and the saw kept straight by use which will cut twice the amount of lumber with the same time spent in filing.
I do not claim the common carriage as shown in the annexed drawings, but what I do claim and desire to secure by Letters Patent is- Simply and substantially raising the tail block as above described or in any otherway substantially the same.
OLIVER B. JUDD.
