Year: 1860

page_text: LETTERS PATENT to Charles Batiste, of Toulouse, in the Empire of
France, for the Invention of "AN IMPROVED WOOD GROOVING MACHINE."
COMPLETE SPECIFICATION filed by the said Charles Batiste at the
Office of the Commissioners of Patents, with his Petition and Declara-
tion on the 14th March 1860, pursuant to the 9th Section of the
Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
BATISTE, of Toulouse, in the Empire of France, send greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED WOOD
GROOVING MACHINE," and have petitioned Her Majesty to grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent for the
same, and have made solemn declaration that I am the first & true
Inventor thereof:-
NOW KNOW YE, that I, the said Charles Batiste, do hereby declare
the following Complete Specification under my hand and seal fully describes
and ascertains the nature of the said Invention, and the manner in which
the same is to be performed, reference being had to the accompanying
Drawings, that is to say:-
The object of the present Invention is a machine for grooving wood in any
manner that may be required, that is, the grooves can be large or small,
partially or ontirely through the wood, and either straight or on the slope, as

page_text: the case may render necessary. The machine is made of cast iron, but the
tools employed are of steel.
Fig. 1 represents a front view of the machine; Fig. 2 represents a side
view; Fig. 3 represents a horizontal section; Figs. 4, 5, 6, 7, views of
different parts of the machine in detail.
The piece of wood to be grooved is placed on a carriage or slide A, Fig. 2.
The carriage can be advanced or drawn back by means of two slides in the
frame B, Fig. 2, of the carriage and moving freely on the pivots C, which are
fixed on the uprights of the machine. The axes of the pivots are thus in the
upper part of the carriage and under the axis of the chisel D, see Figs. 1 & 2.
The piece of wood is adjusted against the caul E, Figs. 1 & 2, and can be
fixed by a double arrangement of screws F. The nut screw H in which the
screw turns can ascend and descend, when a rotary movement is given to the
screw on turning the wheel I, Figs. 1, 2, & 3. Squares can be adapted by
means of screws to the caul E, furnishing at the same time a continuation of
the carriage or slide way. The thickness of the caul E is represented Fig. 3.
The caul can advance or retire from the vertical, passing through the axis of
the chisel by means of the two screws J, adjusted in the thickness of the
carriage, and governed by the wheels K, connected by an endless band. It
will be easily understood that if the screws placed in a groove arranged in
the carriage are fixed so as to be subject to only a rotary movement, and each
passing through a heel or stop made in the caul in the same grooves, the
rotation of the screws would cause the caul to move. In order to give greater
strength to the caul, the heel or stop just spoken of is simply a screw passing
through the caul, and receiving at the end a nut, which presses against the
carriage on the latter being placed in its proper position.
In order to complete the fixing of the wood, the piece L, represented
Figs. 1, 2, & 3, is used. L' is a nut, fixed on the screw governed by the
wheel L", Fig. 1. This arrangement of fixing is adjusted by two screws on
different parts of the carriage, according to requirements. The borer M,
Figs. 1 & 2, receives a rotary movement from the wheel M', connected by
means of an endless band to the wheel M, worked by the principal shaft N.
The borer M during its rotation pivoting on the bottom on the lower plane of
the slope, by which the jointed lever o, o', Fig. 1. is terminated; at the same
-time it can turn in the upper plane of the slope, and thus pierce under the
wood through a passage made for it in the carriage beneath the axis of the
chisel. When this first hole is made in the wood, the square chisel D
transforms the circular shape into a square form. The lower part of the
chisel has a bevel form; it is hollow in the interior its whole length, and is

page_text: adapted by means of two adjusting screws in the tool holders P; it receives.an
up-and-down motion by means of the connecting rod Q, Figs. 1 & 2, attached
to one of the spokes of the wheel Q, governed by the wheel Q" of the shaft N,
so that the tool holders, the upper part of which is square in form, can slide in
the uprights P. It can, by means of a groove which it bears at P, and the
arrangement as represented in the accompanying Drawings, be fixed at
various heights, according to that of the wood. The lower part of the
connecting rod can be adjusted in the same way at various distances on the
spoke, according to the length of the movement of the chisel. The edge of
the chisel can descend about one-fifth of an inch below the plane of the
carriage, in the opening which serves as passage to the borer, and which,
working in a plate fixed to the frame of the carriage, is kept in its proper
position during the movement of the carriage.
The arrangement represented Fig. 5 causes the carriage to move back-
wards and forwards; for this purpose the nut screw S is fixed to the carriage
by one of its ends; through the lower end a screw T, Fig. 1, passes, fastened
to the frame of the carriage by a piece T and by its end, which terminates in
a pivot. The screw T on turning causes the ratchet U, Figs. 3 & 5, which is
bound to it to rotate. This ratchet can itself receive a movement by the iron
rod V, V, a part of which is adapted to roll on the pulley V'. For this
purpose the part of the rod coming in contact with the ratchet is flattened
horizontally, and has a groove in which the ratchet moves. The groove is
furnished with a pivot X, Fig. 5, gearing with the ratchet teeth, which causes
the latter to turn when the upper end of the iron rod is pulled.
Fig. 7 represents an upper view of the rod V, V', which seizes the ratchet
at whatever angle the carriage is placed. The rod is raised by a centre boss
with which it is furnished at the lower part VI, working freely in the upright
of the machine, so that when the spring Y draws back its end from the
starting point, the pivot or stop X catches in a second tooth. If the rod V is
fixed to the tool holders by means of the screw Z, Fig. 5, the course of the
rod, and consequently the movement of the carriage may be increased; thus
the movement of the carriage causes the length of the groove.
The machine is so arranged that on the length of the groove being formed
the movement of the ratchet is stopped, as represented Fig. 6. The piece a
represents that part of the rod in which the ratchet U passes; it is raised by
the rod lever b, which acts on an angle block S', fastened to the nut screw S,
Fig. 5; and when this rod is raised so far that it becomes supported by the
stop, represented side view Fig. 4, against the uprights of the machine, the
carriage proceeds no further.

page_text: If it is required to groove without tracing first the length, the angle block S'
is detached by means of a screw on which it works from the nut screw S. If
the grooves are only to be made a certain depth in the wood, the lever'e, Fig. 1,
must be used; it is made to descend by means of the rod f, which lengthened
adapts itself to the end o¹ of the lever o, o¹, till it is the required depth to
be given to the groove. When the grooves are to be on the slope, as the
carriage swings freely it only requires to be fixed at the desired angle by
means of the compass m. Fig. 1.
The shaft N, Fig. 2, has three pullies communicating directly with the
motive power; one is loose, another governs the chisel, and the third the
upper and lower borers by the two little pullies. The chisel in its movement is
crossed by an iron rod, which withdraws the shavings, a blower, placed
between P and P, Fig. 2, and put in movement by the tool holders, removes
them in their fall, so that they do not pass back into the groove where they
might interfere with the working of the chisel.
Having thus described my Invention, and the manner in which the same
is or may be carried into effect, I wish it to be distinctly understood that
I do not confine myself to the precise details, as the same may be varied or
modified without departing from the principle thereof; what I claim and
desire to secure by Letters Patent is the arrangement and system of apparatus
as above described, and represented in the accompanying Drawings.
In witness whereof, I, the said Charles Batiste, have hereunto set my
hand & seal, this 14th day of March, in the year of our Lord One
thousand eight hundred and sixty.
CH. BATISTE. (L.S.)
