others) that I, the said Pierre Vangeneberg, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Pierre Vangeneberg, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof and accompanying Sheets of Drawings :
:-
This Invention consists in the arrangement and combination of an ordinary
locomotive steam engine for sawing wood and other articles to any shapo or
size required. The main shaft of the engine is caused to actuate direct on
one side a straight saw with a reciprocating motion, and on the other side a
circular saw is provided with a properly arranged carriage, and all other
accessory fittings as in common saw mills, all such fittings being compactly
arranged in a small bulk, and attached to the locomotive engine. The whole
being thus readily removed from place to place as required. The driving
wheels may, however, be taken off when the engine is to be set at work, in
order to give it increased stability.

page_text: In the two Sheets of Drawings hereunto annexed for the purpose of
illustrating my Invention, I have represented several of the modes or methods
of applying the same; the boiler is in all these several views shewn in a vertical
position, but it may be disposed horizontally, if required. In Sheet 1 there are
two distinct and separate arrangements shewn of my improved locomobile
steam saw mills. Figures 1, 2, and 3, shew to the scale of one-twentieth an
arrangement of a locomobile steam saw mill according to my Invention, which
may be preferred to the own shewn in Figures 4, 5, and 6, to the scale of one-
tenth. The same letters of reference being employed in each set of Figures
to denote like or corresponding parts.
Figure 1 is a general side elevational view of the engine and sawing
apparatus complete; Figuro 2 is an end elevation on the side of the stenm
cylinder and circular saw; Figure 3, an end elevation on the side of the
vertical saw.
A is the foundation or sole plate; B, boiler; C, C', framing pieces support-
ing the machinery necessary for working the saw blades; D, E, the saw
frames; F, steam cylinder; G, connecting rod; II. II', Ay wheel and pulley
carried by the shaft I; J, the circular saw, which is actuated by the band
M, M, working over the pulleys L and II; O, the straight vertical saw blade,
the reciprocating motion of which is given by means of the connecting rod P,
the superior extremity of which works upon a stud or pin projecting, as shewn,
from one of the arms of the pulley H. The block of wood to be sawn (and
which is shewn by dotted lines in Figure 1,) is carried forward by fluted
rollers revolving upon the supports T; V, the rod, which, through the inter-
vention of the gearing (shown in Figure 3) gives the necessary motion to the
said rollers. Smooth rollers are also provided for bearing upon and guiding
the wood as it moves forward, these latter rollers revolving upon the supports
U (Figure 1). Axles X, X, aro secured to the boiler, upon which the driving
wheels aro mounted, so as to render the machine capable of easy removal.
Figure 4 (Sheet 1), is a plan of another modification of my improved
locomobilo steam saw mill; Figure 5 is a front elevational view, shewing the
steam boiler, cylinder, straight vertical' saw blade, and apparatus for working
the same; Figure 6, side elevation, shewing on one side the steam cylinder
and vertical saw blade, and at the opposite side thereto the circular saw
and table.
A, vertical boiler; B, steam cylinder, bolted fast on the boiler; D, D, piston
rod guides; E, E, sliding blocks or cross heads at each end of the piston rod;
F, connecting rod working the crank G keyed on the shaft II, which shaft
carries also the fly wheel or pulley 1; the circular saw M is adjusted on the

page_text: shaft J, which rotates in bearings fitted on the frame N; the wood to be
sawn (by the circular saw) is placed upon the table O against the move-
able guide P, the circular saw is driven by the band Q running over the
pulley K. The motion for driving forward the log to be sawn by the
vertical saw is supported by a standard or frame R. The saw blade F' is
attached to the sliding blocks or cross heads E; the log is carried forward by
fluted rollers S, actuated by the pinions T, U, eccentric A', and rod B¹; the
latter works the ratchet wheel W by means of the pall X and the jointed lever
arm Z, the wheel W being stopped by the retaining pall or click Y. Smooth
pressure rollers V steady and guide the log as it moves forward. D¹, guiding
rods of the rollers V. The vertical saw blade F¹ works in the fixed guide H¹
and moveable one J¹. Axles G, G¹, secured to the boiler are provided with
wheels to allow of the removal of the engine. In this latter machine the
vertical saw is attached to both cross heads E, E, of the piston rod, so that
the reciprocating motion is produced directly by the strokes of the piston, and
I am thus enabled to construct vertical saw mills, requiring less height than is
indispensable in common vertical reciprocating steam saw mills. In most
steam engines the crank shaft is used only as a moving shaft, whilst in this
machine it is at the same time a moving and intermediate shaft; thus the fly
wheel I is also the driving pulley for working the circular saw by means of an
endless strap. The eccentric A¹, before referred to, actuates the rod B', to
which is connected (by means of the jointed lever Z) the click X, which at
each revolution of the shaft II causes the ratchet wheel W, keyed fast on the
same shaft as the pinion E', to move round one tooth. The pinion E¹, through
the intervention of the other pinions shewn, gives motion to the fluted rollers S,
between which and the smooth roller V the log is passed, and which by this
means is caused to move forward progressively.
In Sheet 2 there are other various modifications shown in the arrangement
of locomobile steam saw mills constructed according to my Invention.
Figures 1, 2, and 8, shew respectively a side elevation and two end elevations
of a steam saw mill furnished on one side with several straight vertical
reciprocating saw blades, and on the other side with a circular saw and a
moveable table for the latter. A is the boiler; B, steam cylinder; C, main
driving shaft; D, fluted rollers for driving forward the log to be sawn by the
vertical saw blades; E, rollers supporting the log, shewn in Figure 2. These
rollers are carried by the table T (and cannot be seen in Figure 1). F, stud
or pin fitted on the fly wheel; G, cross pieces of the sliding frame, carrying
the vertical saw blades H, H; I is the connecting rod of the engine, working
the fly wheel Y; J, J, studs or pins on lower fly wheels R, R', to which aro

page_text: attached the side rods K, K, employed for working the sliding vertical saw
frames, the superior extremities of the rods K, K, being attached to the ends
of the top cross piece W of the sliding frame. The lower fly wheel R is
actuated by an endless strap or band S running over the pulley Q A framo L
supports the fluted rollers D, driving forward the logs to bo sawn by the
vertical saw blades; N, supporting frame of the circular saw U. The
moveable table T of the circular saw travels on rollers a, a, the axles of which
work in bearings formed in the standards V, bolted fast on a wooden frame d, d.
The pulley Z of the circular saw is driven by means of the endless band f
working over the fly wheel Y. The machine is erected upon a foundation or
sole plate e, c.
Figure 4 front view, Figure 5 plan, and Figure 6 an end view of another
modification of a steam saw mill constructed according to my Invention. In
this arrangement there is no circular saw, but two reciprocating vertical saws
are employed, one on each side. This description of saw mill is called
"scicrie à cylindre," as also those which have previously been herein described,
in which the log is carried forward by means of fluted cylinders. A is the
boiler; B, steam cylinder; C, crank shaft of the engine; D, crank; I, tho
connecting rod. There are two fly-wheels E, E, provided with studs or pins J,
upon which work the driving rods K, the lower extremities of these rods
being attached to the saw blade holders N, N¹. Tho fluted rollers L drivo
forward the log to be sawn, and which is pressed by guiding rollers M. The
saw blade is adjusted betwixt the cross pieces N, N¹, forming a sliding frame
(a detached viow of one of these is shown at Figure 9). The driving rod K
works through the upper cross pieces N, as shewn in the detached plan view
Figure 10. The whole machine rests upon a sole plate e, on which are bolted
fast the cast-iron supporting frames O, O, and P, P.
Figure 7 is a side view, and Figure 8 a front elevation of another arrange-
ment of locomobile steam saw mill according to my Invention, provided with
only a circular saw, and so adapted as to saw the logs crossways, and intended
principally to be employed in the preparation of wood for making charcoal in
forests and other similar places. A is the boiler; B, steam cylinder; C,
driving shaft; E, fly wheel; and E pulley keyed on to the shaft C; F', stud
or pin, upon which works the connecting rod I. The pieces of wood J to be
sawn across are placed on the movable support G, which is carried by and
can move upon the axle II. The wood is held by the hand lever i. The
circular saw U is fixed on the shaft a, which carries also a small pulley Z,
which is driven by a band or strap running over a pulley keyed on to the
intermediate shaft c', the other ond of which shaft is also provided with a

page_text: small pulley, which is driven by means of another band running over the fly
wheel E. The driving shaft C works in bearings d, d, bolted on to the
boiler. The shaft a of the circular saw works in bearings formed in the
standard b, bolted on to the foundation or sole plate e. The pieces of wood
when sawn off drop down upon a curved table f, by which they are discharged
clear of the machine.
Having now described the nature of my Invention, and the manner in which
the same is or may be carried into effect, I wish it to be observed that I do
not confine or restrict myself to the precise details or arrangements which
have been described, and illustrated in the annexed Sheets of Drawings, as
other modification thereof may be made without deviating from the principle
or main feature of the said Invention; but what I claim is, the arrangement
and combination of common locomobile steam engines, so as to drive directly
with the said engines, either on one side a straight saw with a reciprocating
motion, and on the other side a circular saw, or a straight sawing machine on
both sides, the said sawing machine being composed either of one or several
blades; or there may be one or more circular saws with steadying or moveable
guiding tables; and whatever may be the combination, so that the said
machine, being compact and of small size, can be mounted or supported upon
wheels, complete within itself, and easily removeable from place to place.
In witness whereof, I, the said Pierre Vangeneberg, have hereunto set
my hand and seal, this Third day of December, in the year of our
Lord One thousand eight hundred and sixty.
