PORTABLE OROSS-OTJT SAW MILL. 
FOR HORSE POWER. 
Plate IV. 
§ 38. Drag Cross-Cut Saw Mills, for cutting off logs for making staves, shingles, firewood, 
&e., &e., by horse power, are of recent invention. There have already been a great number 
variously constructed, and made by different persons, and with various success. Among the 
many inventions none are believed to be as well adapted for both the work and power as 
that illustrated in plate iv. 
§ 39. It is constructed with a substantial wood frame about eight feet long, which is fastened 
down upon the ground when in use. Across one end of the frame is hung a substantial 
shaft, carrying a balance wheel and band pulley combined, outside of it, and weighing 
together about one hundred and fifty pounds. In the face of the wheel is fixed an adjustable 
wrist pin, which can give from twelve to thirty inches stroke. At the other end of the 
frame is attached a pair of iron ways and a crosshead, also carrying a wrist pin. A stiff 
wood connecting rod connects this crosshead with the wrist pin of the balance wheel.. 
The saw is attached to one end of a light stiff wood shaft, which passes between upright 
guides near to the log and extends and is attached to the connecting rod at a point 
between its crosshead and balance wheel ; connections as shown in plate iv. This arrange- 
ment gives to the saw, when cutting, a rolling motion, and as the balance wheel turns over 
towards the log it raises the heel of the saw ; in moving towards the log and lowering the 
heel it raises the point in the returning motion, enabling the saw to cut both ways and at a 
high velocity and avoids carrying bark, slivers, dirt, &c, into the kerf from either side ot 
the logs, and. without any increased liability of damage over the simple draw-cut machines. 
§ 40. The log "ways, truck and spiked roller are simple in arrangement and can be made by 
any wood mechanic. Those manufactured and sold with the machines are simply two good 
sill timbers, 4 by 5 inches square, twelve feet long, framed with cross girts with a spiked 
roller at one end and a four wheel truck, which traverses the length of the ways. The 
log is rolled upon the ways and one end lays across the spiked roller, near which the saw 
cuts. The truck is placed under the other end of the log, and by hooks or dogs,, the log 
is fastened to it. The roller extends outside the ways with a capstan head, and the log is 
moved forward by means of a lever applied to the roller head. The truck travels forward 
with the log until it reaches the spike roller and the log is all cut up. The spike roller 
and truck are shown in the bottom corners of plate iv. 
§ 41. Its capacity, with Emery's One Horse Power, is about hundred cuts three feet in 
diameter per day, and like amount of larger or smaller, logs of any kind of wood, and 
nearly double amount with two horse power. 
Measurement, about twenty-four feet. Weight of mill four hundred pounds of ways, 
roller and truck, three hundred pounds additional. 
Price of saw mill, with 5% foot saw, without the roller, truck and ways, $40 
Price of roller, truck and ways, ......... 20 
They are sold separately or together, as desired. 
CIRCULAR CROSS-CUT SAW MILL. 
FOR POWER. 
Plate TV. 
§ 42. This is a simple, cheap and effective 
machine for sawing wood, shingles and any 
kind of work required by the farmer for 
fencing, or carpenters for slitting and cutting 
up lumber. With a 24 inch cross-cut saw, 
rigged as shown in the annexed cut and 
plate iv., it is used for sawing wood, and 
with three men and one horse will cut, twice 
in two, from ten to fifteen cords of cord- wood 
per day. With two horses all that five men 
can handle can be cut per day, and is uni- 
versally used by railroad wood sawers. It 
has a heavy plate balance wheel (instead of 
spokes as in the cut) also a ratchet pulley 
for the belt. Measures 26 feet, weighs 350 
pounds. Price, with 21 inch saw in work- 
ing order and warranted, §37. 
$ 43. An attachment for slitting boards, &c. , with 14 inch saw and table, extra $7. A shingle 
saw attachment, with 24 inch shingle saw in working order,, with slide table, guides, &c, 
complete to fit the mill, extra, $40.
