UNITED STATES PATENT OFFICE
WILLIAM CRITTINGTON RODGERS, OF OWLET GREEN, TEXAS, ASSIGNOR OF
ONE HALF TO FRANKLIN P. LYBRAND, OF SAME PLACE.
PORTABLE SAW-MILL.
SPECIFICATION forming part of Letters Patent No. 296,220 dated April 1, 1884.
Application filed December 8, 1883. (No model.)To all zL hom it may co07ce7-':
Be it known that I, WILLA C. RODGERS,
a citizen of the United States, residing at
Owlet Green, in the county of Van Zandt and
5 State of Texas, have invented certain new and
useful Improvements in Portable Saw-Mills;
and I do hereby declare the following to be a
full, clear, and exact description of the inven-
tion, such as will enable others skilled in the
io art to which it appertains to make and ns6
the same.
The object of this improvement is to pro-
duce a portable saw-mill of such cheap and
economical plan as can be built and repaired
15 in almost any locality.
The invention consists in the peculiar con-
struction and arrangement of the parts, as
will be hereinafter fully explained and spe-
cifically claimed, reference being had to the
20 drawings herewith filed as part hereof, and
in which similar letters of reference denote
like parts.
Figure 1 is a side elevation, partly in sec-
tion. Fig. 2 is an end elevation with some of
25 the parts removed and some in section, to bet-
ter illustrate the construction. Fig. 3 repre-
sents some of the details partly in section.
A is the track-frame of the mill, which is
to be mounted at both ends on transporting-
30 wheels B.
C is an upright post or beam bolted to .the
frame A, and provided at its upper end with
a rectangular projection or bracket, S, which
may be affixed to post C by mortise and tenon,
35 as shown at R, or in any secure manner. To
the bracket S are affixed journal-boxes,which
form bearings for. trunnions k of the vibrat-
ing box K, which acts as an arbor for the
guide-bar I, having eyes at its lower end, to
40 which the upper end of the saw G is affixed
by bolts g. Below the track-frame A, and lo-
cated centrally therewith, are perpendicular
beams a", tenoned to the track-frame A, and
braced in position by the angled beams a',
45 tenoned to the frame A and to the perpendicu-
lar piece a", and further secured in position
by cast - iron plates N, which embrace thejoints so formed, and are made fast thereto by
wood -screws n. A pair of double-1flanged
castings, D and D', connected by integrallugs 50
d, are secured in a vertical position to the
perpendicular beams a" by the screws d' near
their lower ends, and to the frame A by
flanged metal plates and wood-screws, as shown
at b. A counterpart of the double-flanged 55
casting D is bolted thereto by means of per-
foratedlugs corresponding to the lugs,as shown
at d. The double-flanged castings D D', thus
united, form an arbor, as shown in Fig. 2, for
the cross-head E, to which the lower end of 6o
the sawGis secured. Pendent from the cross-
head E are plate-links F, to which the pit-
man P is connected with the saw, thence with
the crank H on the shaft 3S, which is oper-
ated by pulley J, to be connected by the usual 65
belt with driving-power. The frame should
be elevated, sufficiently to clear the machin-
ery both for transportation and operation.
The carriage V, for feeding the log T to the
saw, is stopped while the log is hoisted to the 70
carriage by means of skids connected with the
side of the frame A. The log is fed to the saw
automatically by the usual appliance, which
is not shown, as no claims are to be made in
such regard. 75
The motion of the driving-shaft I will give
action to the saw G, which, by reason of the
guide-bar I and vibrating box K, will vibrate
to and from the dotted line, as shown in Fig.
1, and clear the cut going and resume it on the So
downstroke.
Having thus explained the construction and
operation of my improvement, what I claim as
new, and desire to secure by Letters Patent,
is as follows: 85
1. In a reciprocating saw mill, the vibrat-
ing box K and guide-bar I, operating therein,
in combination with the saw G, cross-head E,
having pendent links F, for connecting with
driving-shaft through pitman P and crank H, 90
and the cross-head arbor formed of the plates
D D', all constructed and arranged to operate
substantially as specified.
2. The mounted frame A, provided with
