Description

UNITED STATES PATENT OFFICE.
GILBERT H. CLEMENS, (U. S. A.,) OF CINCINNATI, OHIO.
IMPROVEMENT IN SAW-MILLS.
To all whom it may concern:
Be it known that I, GILBERT H. GLEMENS, (U. S. A.,) of Cincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Saw-Mills; and I do hereby declare the following to be a full, clear, and eX- act description thereof, reference being had to the accompanying drawings, making part of this specification.
My invention relates to a rotary shifting knee adapted to be set in either of two positions, according as a round or square log is to be sawed, and also in providing the knee with a friction roller or rollers, so as to enable a heavy log to be turned on the head block with the greatest facility. l
Figure 1 is a side elevation of my rotaryshifting-knee attached to a head-block. Fig. 2 is a plan of the sanne. Fig.3 is a transverse section at the line xxof Fig l, looking upward. Fig. 4 is an end elevation ot' the knee, and Figs. 5 and 6 are perspective views ot' the knee and dovetailed boss detached.
A represents a head-block of any approved construction; and B is the base-plate ot the knee, capable of being advanced or retracted by any suitable setting-screws, C C.
D is a circular dovetailed boss. which may be cast solid with the base-plate B. The boss D is provided with lips E E and intervals F F', said lips and intervals being of nearly equal length, or about one-fourth of a circle each.
G is my rotary shifting-knee, having a circular dovetailed base, H, which surrounds the boss D in such a manner as to turn freely on it as on a pivot. The base H has lips I I' and intervals J J', which correspond with the lips and intervals ot' the boss D.
h h' are countersunk set-screws, by which the base H is secured to the boss D in any desired position.
The rotary shifting-knee G has one vertical face, K, and one receding concave face, L,and the latter is provided with a series ofjournalbearings to receive one or more friction-rollers, O. The object ot' this friction-roller is to.
enable the log to be rolled or turned around with very little labor, and without any injurious strain on the knee or head-block.
When the log` is smallin diameter the roller O may rest in the lowerbearing; but the roller is shifted to one ofthe upper bearings when a large log is to be sawed; or a series of -rollers may be used, if preferred. The log having been "slabbed7 olf, the knee is Iliade to perform a half-revolution, which brings the vertical face K to bear against the square side ot' the log'.
The knee can be lifted bodily from the boss D by bringing the lips I I ot' the knee to correspond with the intervals F F ofthe boss.
Disclaimingareversible connection,broadly, such devices being seen in various connections, such astool parts ot lathes,
I claim herein as new and of my invention- 1. The rotary shifting-knee G, having lips I I' and intervals J J', in combination with the circular dovetailed bossD on the base-plate B.
2. The construction ot' a saw-mill knee with a recedingconcave face, L, having one or more friction-rollers, O.
In testimony ot' which invention I hereunto Witnesses:
GEo. H. KNIGHT, J AMES H. LAYMAN.
