ITARVEY MOREY AND SAMUEL Ii. BELLAI, OF CAMERON, TEXAS.
IMPROVEMENT IN SAWING-MACHINES.
Specification forming part of Letters Patent No. 146,839, dated January 27, 1874; application filed
September 6, 1873.To all whom it miay concern:
Be it known that we, HARVEY MonEY and
SAIIUEL H.BELLAII, of Cameron, in the county
of Milam and State of Texas, have invented a
new and Improved Portable Sawing- achine,
of which the following is a specification :
The invention will first be fully described,
and then pointed out in the claim.
Figure 1 is a plan view of our improved ma-
chine; and Fig. 2 is a sectional elevation of
Fig. 1, taken on the line x x.
Similar letters of reference indicate corre-
sponding parts.
A represents a frame, mounted on a truck
of, preferably, three low wheels, B, with which
said frame is provided, also horizontal ways
(I, for a saw-frame, D, to slide forward and
backward in, the saw projecting at one side
of the frame, as shown in Fig. 1. Said frame
is also provided with vertical ways D', into
which the saw can be shifted when it is de-
sired to saw felled trees into blocks. This
saw-frame has a forked pitman-rod, E, attached
to each end, one of which is connected directly
to the crank F of the driving-shaft G, and the
other is connected to the rock-lever H, which
is connected by the rod I to another crank, IT,
on said shaft, the two cranks being arranged
at opposite sides of the axis. The crank-shaft
is geared by multiplying wheels K with the
hand crank-shaft L, which has a crank at each
end for being turned by a man at each. The
saw-frame has a feed-screw, M, fitted in a slotted
bar, N, with a collar, 0, at each side of said
bar, so that it can feed the frame forward andback, while said frame reciprocates to work
the saw. The screw works in a nut fixed on
the frame at P, and gears by a long nut, Q,
with a counter-shaft, IRI and pinion, which is
turned by the feed-belt S, working from the
crank-shaft G.
When it is desired to arrange the saw ver-
tically for enttingthefelled trees up into blocks,
the feed-screw andthe rods E are disconnected,
the saw-frame shifted up into the vertical ways
D', and again connected to rods E, suitably ar-
ranged for the saw in that position. The crank-
shaft Ci and the point of connection, T, with
the rock-lever H are arranged as high above
the saw-frame when it lies in the horizontal
position as can well be and work well, so that
they will be high enough to work well with the
saw-frame when it is arranged vertically for
cutting off the felled trunks. To protect the
driving-gear, we build a box, U, around it, and
provide said box with a hinged.cover to afford
access.
Having thus described our invention, we
claim as new and desire to secure by Letters
Patent--
The combination of the two connecting-rods
E, rock-lever H, and connecting-rod I with
the said saw-furame and double-cranked shaft
(G, substantially as specified.
