Improvements in Wood Carving or Shaping Machines.
1, HONESTUS MORTON ALBEE, of No. 3 Orange Place, in the City of Newark,
County of Essex, and State of New Jersey, United States of America, Manu-
facturer, my post office address being No. 3 Orange Place, Newark, N.J., do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-\
This invention relates to certain improvements in that class of woodworking
machines illustrated in my Patents of the United States of America, Nos. 354,997
and 404,945, the objects of the present improvements being to increase the
capabilities of the machine, so that it will be able to accomplish or perform a greater
variety of work in the shaping of wood or the carving or similar ornamentation of
the same, and to secure other detail or specific advantages and results some of
which will be set forth in connection with the description of the working parts.
The invention consists in the improved woodworking machine and in the arrange-
ments and combinations of parts, substantially as will be hereinafter set forth and
finally embodied in the clauses of the claim.
Figure 1, is a plan of the improved woodworking machine showing a jointed
arm carrying a rotary cutter or routing or carving tool and attachments for guiding
the said tool both horizontally and vertically in correspondence with a pattern
arranged on a table, the said table being suitably arranged beneath the said tool;
Figure 2 is a side elevation of the same,
Figure 3 is an enlarged detail showing more clearly the connection of the
guiding or controlling mechanism with the head of the jointed arm,
Figure 4 is a side view showing a certain sliding plate and its bearings on the said
jointed arm,
Figure 5 is a section of the same on line .c,
Figure 6, is a section on line

Figure 8 a side view of the same,
Figure 9 is a section on line :, and
Figure 10 presents detail views of tracing tools which may be employed with
connection with the pattern.
In said drawing, a, indicates any suitable fixture or support for the horizontally
vibrating arm ; a', a', indicate metallic brackets, secured to said fixture and
providing bearings for a pulley shaft, a², and for a pivotal support for the section 61
of the said arm b.
In the prior devices above referred to, the jointed vibrating arm, b, was in but
two pivotal sections, the section corresponding to 63, herein, being pivoted directly
upon the section corresponding to section . In the improvement, I have provided
an intermediate section, 62, and an additional pulley shaft and belt. Thus the scope
of the arm is largely increased and certain kinds of carving can be performed
without changing the block or board operated upon, which would heretofore have
required a readjustment.
The
On the outer pivotal section, 13, is a vertically movable section, b, which is
movable horizontally with said section 3, but not independent thereof.
vertical movement of said section, 4, on said section, 63, is controlled by an
adjusting screw, 66. Said section, 64, provides bearings for the rotary tool shaft, f,
which receives its motion from the pulley f', belt d³, double pulleys f, f³,
pulleys, and belts d², d¹, d, from any suitable source of power as will be
understood.

page_text: The tool shaft, f, lies parallel with the pulley shafts a², a³, a³, and thus the
tool may be moved, while rapdily rotating, in any direction in a horizontal
plane.
In the device shown in U.S. Patent 404,945, the jointed arm, b, and its
rotating tool is shown to be provided with a guide rod and carriage attachment by
means of which the said tool can be guided horizontally in accordance with a
pattern arranged on a table or bench stationed beneath or near the vibrating arni.
But by the construction therein shown, the tool was only movable in a horizontal
plane and the ornamental work resulting from the tool was flat, or the tool merely
gave outline to the ornament without affecting. the outer face thereof. By means
of the present improvements in addition to the varieties of work that could be
accomplished by the machine as heretofore constructed, the machine is capable of
producing bas-reliefs of any shape (provided there be no undercuts) whether the
outer surfaces of the ornaments be flat, convex or concave.
To secure these additional results, in addition to the movements in a horizontal
plane and the vertical movement with the section under the action of the adjusting
screw 6, the shaft, f, and its cutter or tool g, have a vertical movement independent
of the section 6', controlled by the guide rod 616, whereby the said tool not only
outlines the ornament on the bas-relief but may also give the desired convexity or
concavity to the outer surfaces thereof, in accordance with the pattern employed in
giving direction to the said guide rod.
At the lower side of the section 1, of the jointed arm, a pivotal bearing, 1,
Figure 5, is formed, through which the shaft, f, passes and on which is arranged an
irregularly shaped plate, 68, which is held up to the said bearing by a nut, b, and
is thus removable from the section, 64, to allow other attachments to be substituted
when a different kind of work is to be done. From a depending lip or bearing, 410,
of said plate, 8, a guide rod, 61, Figs. 2 and 3, extends away from the arm to a
carriage, h, Fig. 7, constructed to slide on a track or way, i, of the table j, Fig. 2.
The bearing, o, is perforated in two directions as clearly indicated in Figures 3
and 5 to enable the rod, b, to be changed in position to accommodate the machine
to certain conditions of work.
At the opposite side of the plate, 68, are vertical bearings, 612, to receive a
sliding plate, 63, having a connection, 4, with the shaft f, the said shaft being
provided with a peripherally grooved collar, 61, Figure 5, vertically movable with
said shaft f. The method of fixing the said collar to the shaft is shown in
Figure 5, where the ends of the pulley, f', are shown to be hollowed out to receive
the nuts f¹³, f. The grooved collar 61, is provided with a threaded shank, 14,
which extends through a perforated end plate, 15, of the pulley and receives the
said nut on the inner side so that said collar, 15, is prevented from becoming
detached from said end plate yet the said plate, 15, is allowed to move pivotally
independent of the collar. The said plate f" is then fastened to the pulley by
means of screws 16 or other means and the pulley is set to the shaft, f, by set
screw f".
The grooved portion of the collar projects above the pulley so that, as the
sliding plate, 613, moves vertically in its bearings, 61, on the plate 6, the said
shaft, f, will be moved with it and the cutter or tool, g, be raised or lowered in its
relation to the board or piece of wood being worked upon.
To guide the plate, 61, in accordance with a pattern, k, Fig. 1, arranged on the
table at a distance from the tool, I have provided a horizontal rod, 61, Figs. 1, 3, 6,
secured to the bearings, 617, at the lower extremity of the plate, 613, on which is
arranged an adjustable carrier, 618, Fig. 3, for a tracing point, 69, which latter is
also adjustable and is adapted to bear on the upper surface of the pattern and to be
raised or lowered with its carrier and the parts connected therewith in accordance
with the elevations and depressions of said pattern.
The sliding plate, 613, has a limited movement in its bearings sufficient however
to secure the necessary elevations of the bas-relief. It is held in said bearings by
a suitable plate, 620, Figs. 4 and 5 and provision is made for securing a steady

page_text: movement of the parts, the preferred method being to provide a centre boss, 621,
shown in Figs. 4 and 5, which projects from the face of the plate, 62, into a slot 22,
formed in the sliding plate 613.
To enable the sliding plate, 13, tracing point, 1,19, and the shaft f, and the parts
connected therewith to be raised freely and easily so that the pattern can be
accurately traced without undue exertion and injury to the pattern, I have provided
a counterbalance weight, 1, Fig. 3, which is adjustably arranged on the extremity
of a lever l, pivoted on a fulcrum, 12, formed on or secured to the section, the
inner end of the lever being forked at 13, to engage a grooved collar, I, arranged
in connection with the pulley in the manner described in connection with the
collar at the upper end of said pulley, (except that a pin limits rotation). The
weight, tends to counterbalance the weight of the vertically movable parts, so
that the points 1, may be traced over the irregularities of the pattern with ease.
The carriage, h, is of improved construction and admits of peculiar results being
secured. In the carriage shown in my prior Patent 404,945, the centre of
movement of the pivotal plate, corresponding to the one herein marked ', was
excentric to the line of movement of the bar ". In the improved device, the sai.l
centre of movement of the plate is in the line of the guide rod ", and thus
certain results of bevelling may be accomplished, that cannot be readily performed
by the prior construction.
To secure the pivotal movement without interference with the guide rod, the
under plate of the sliding carriage is provided with a pivotal lug, , which works
in a recess in the upper plate and the plate is held down to the plate, ³, by set
screws,, which work in concentric slots h. By turning the plate on its centre
to the desired position and setting the screws, 6, the desired direction of bevel can
be secured. A bridge 48, with its set screw, holds the guide rod in its bearings h¹³.
To hold the routing or carving tool stationary with reference to lateral movement,
and to enable it to be employed as a moulding cútter by guiding the wood against
the cutter rather than the cutter over and against the wood, I have provided the
guide rod and track, i, with stops,, Fig. 1, which when set against the
opposite edges of the parts h', h³, respectively prevent any longitudinal movement
of the latter as will be apparent. By setting the stops further apart so as to admit
of a limited movement of the carriage and guide rod, as shown in Fig. 1. The
four sides of a panel, having a carved surface or otherwise, can be quickly
worked out.
By means of the set screw ¹, the sliding carriage may be held against
lateral pressure and thus prevented from sliding on the track or way i, as will be
apparent.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
