Specification Accepted, 30th Sept., 1887.
We, ADAM REICHERT and GEORGE SHRIVER QUIGLING both of Tiffin in the
county of Seneca and state of Ohio one of the United States of America, Gentlemen
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to certain improvements in log-sawing machines of that
class in which the device is fitted to the log to be sawed and operated by means of
suitable levers; and it has for its objects to give a direct thrust to the saw and
elevate the frame as occasion requires, as more fully hereinafter specified.
The above-mentioned objects we attain by the means illustrated in the accom-
panying drawings, in which-
Fig. 1 represents a side elevation of our improved machine; Fig. 2. an enlarged
Elevation and part sectional view of the same; Fig. 3. an enlarged Elevation of the
sliding frame of our machine detached, and Fig. 4. a detached view of one of the
guide-hangers forming part of our improved apparatus.
The letter A indicates a rectangular beam, which near its forward end is provided
with a spike B, adapted to set into the log C, so as to keep the beam and the log in
the proper relative positions during the operation of sawing.
D. indicates a vertical frame, which is provided with ways E, in which is adapted
to move a frame, F, forming the rear part of the beam A.
The said frame D. is provided with a base, G. which rests upon the ground when
the machine is in position.
The letter H indicates a vertical ratchet-rod, forming part of the frame D., and I
a pawl adapted to engage the ratchets of said rod, so as to hold the frame in any
properly adjusted position.
To each side of the beam are pivoted or fulcrumed the levers K, the lower ends of
which are provided with treadles L, by means of which the levers may be operated
by foot.
The upper arms of the levers serve as handles, by means of which they may be
operated by hand.

page_text: In the frame F is journaled a transverse shaft, M, which is provided with cog-
pinions N, which are engaged or intergear with the rack-bars P, secured to the lower
ends of the operating-levers.
These pinions serve to move their shaft in reverse directions when operated by the
rack-bars.
To the shaft M is secured a pinion or cog wheel, R, which intermeshes with the
rear end of a rack-bar, S, to the forward end of which the saw T is secured.
The respective rack-bars are kept to their intergearing pinions by means of
the friction rollers U, mounted on the angle-backets V. which are pivoted to the
shaft M.
W indicates a seat mounted upon the beam A, upon which the operator sits while
working the saw.
The operator, in manipulating the machine, takes his position upon the seat, the
beam being arranged in connection with the log, as shewn in Fig. 1 of the drawings.
Then by operating the levers by foot and hand, through the reversely operating
gearing, the saw is thrust back & forth as required. To elevate the saw and adjust
it to its work, the pawl and ratchet-bar are brought into use, the pawl serving to
hold the frame to any desired position upon the ratchet bar.
Having now particulary described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is
1. The combination, with the horizontal beam A, and the upright beam to which it
is secured, of the levers K K, pivoted to said beam A, the rack-bars P. P, pivoted to
said levers, the cog pinions N N, secured to the common shaft M, and intergearing with
said rack-bars, the cog-wheel R. mounted on said shaft M, and the rack-bar S. with
which said wheel R meshes, the said rack bar carrying the saw to which it gives a
reciprocating motion, substantially as specified.
2. The combination, with the rack-bars P, P and S and the cog-pinions N, N, and
wheel R. of the friction-wheels U, mounted on suitable arms and bearing upon the
respective rack-bars to hold them in gearing with the cogged pinions and wheel,
substantially as and for the purposes specified.
3. The combination, with the main frame D and beam A, of the sliding frame F,
the cog-pinions N N, and wheel R, mounted on a common shaft, M, journaled in the
frame F, the rack-bars P. P. and their operating-levers, and the rack-bar S. carrying
the reciprocating saw T. the whole arranged to operate substantially in the manner
and for the purposes specified.
