page_text: the table and the upper bar of the said frame is pivotally connected to the upper section
of the post which is detachably connected to the lower fixed section of the post.
The rear terminal ends of the bars s and s¹ of the jig-saw frame are connected
together by an intermediate swivel T¹ whereby the tension or force exerted by the bars
on the saw blade can be regulated the said blade being securely affixed by any preferable
means in the opposite inner ends of the parallel bars 8 and 3 of the frame and working
through a vertical opening in the table a¹.
The blade of the jig-saw is in proximity to an adjustable gage T' on the table similar
to gage F
The saw frame is reciprocated by a link t connected to arm p³ of the rock-shaft and
the lower bars of the frame. When the band p¹ encompasses the pulleys D and
the shaft R is rotated and the motion thereof is converted and transmitted to shaft P
by the intermediate connections, and the motion of the rock-shaft is communicated to
the jig saw frame S by the link the bars of said frame being pivoted to permit of
the vertical play or reciprocating movements of the inner end of the frame and the
saw blade therein.
The upper bars and the blade of the frame S can be readily detached from the
machine when it is desired to employ any other part of the machine, by first disconnecting
the swivel and blade and then releasing the upper section of the post from the dowel-
pin. The belt is removed from the pulleys D. and the lower bar s¹ of the machine
being beneath the table of the main frame, other work can be performed or carried on
upon the same by the other mechanisms without hinderance from the jig sawing
mechanism.
The forming or molding mechanism is similar to that hereinbefore described a
vertically sliding frame U being adjustable between vertical guide bars arranged at
a suitable distance apart and secured to the main frame, the vertical sides of frame U
fitting in grooves in the guide bars.
The upper end of the shaft U' of pulley U₁ is extended above the frame and said
end is threaded as shown in Fig. 6ª and on this end is fitted a tubular sleeve u¹ which
holds the fixed cutters u³ in place. The sleeve and its cutters are held in position by
a nut fitted on the upper threaded end of the shaft.
u.
The sliding frame is held in its elevated position by a binding screw U³ working in
an opening in one of the guides The belt which drives the pulley U¹ slips over the
same or is moved therewith when the frame is moved upwardly to adjust the cutters
for operation.
The sliding frame is lowered and the cutters drawn beneath the table when it is
desired to use the machine for other purposes than forming moldings.
V designates a horizontal shaft which is arranged above the main driving shaft and
in rear of the same and this shaft is journaled in suitable bearings that are rigidly
affixed in the main frame A. The shaft carries a band wheel which is belted to the
large pulley D to be driven by the driving shaft and it carries another pulley V₁ which
is belted to the pulley U¹ by a belt V2 so that the former is positively driven or rotated
from the driving shaft. The former is capable of a vertical movement without
hinderance from belt V2 and it is adapted to be rotated by the belt at any height or
point of elevation.
The mechanism for rounding square or angular rods is almost identical in construction
with that hereinbefore described.
The rotary head W mounted on the hollow shaft V3 has the central opening wo and
an enlargement w on its rear side said shaft V³ carrying a pulley 5 affixed thereto
which is driven from pulley C.
wo is the binding screw for securing the head on the shaft; is the recess in the
head in which is fitted the disk W¹ having apertures w³ of unequal diameters therein.
In this construction, the notches shown in Fig. 6 (ff) are not provided.
X is a radial support fixed to the head W against which the knife or cutter Z bears.
The latter is, in this instance, adjusted towards the center of the head by means of a
longitudinal slot made in the support X and a threaded bolt or screw passing
through the slot and connected to the knife Z, said screw being held in its adjusted

page_text: turned to adjust the tightener pulley away from the band pulleys and thereby tighten
the band.
When the driving shaft is rotated either by power from the treadle or the counter
shaft, the pulley D causes the band to move and pass over the idler and tightener
pulleys and the guide M can be readily adjusted as desired.
When the band saw is employed a removable table O2 is connected by locking
devices with the horizontal table a' of the main frame as shown in Fig. 1. This
table supports the work that is operated upon by the band saw and is arranged at one
side of table a¹ and in the same plane.
I will now describe the jig saw mechanism which is constructed and operates in the
same manner in both machines. P is a rock-shaft journaled in boxes p on the sills a ;
to the opposite ends of said shaft are connected arms, p¹, p². One of these arms, p¹
is pivotally connected to the lower end of a link p³ likewise connected at its upper
end to a crank pin Z rigidly affixed to one end of a crank arm Q rigidly affixed to
and rotating with shaft R which is journaled in suitable openings formed in or secured
to a swinging hand lever R¹ which is arranged in a horizontal position at one end of
the main frame. The lever R¹ is supported on a friction bolt r at an intermediate
point of its length and the lever is capable of movement on the bolt under the
pressure of the operator's hand thereon, the lever being held against movement by the
frictional contact of the bolt with the walls of the opening in the lever through
which the bolt is passed. The bolt is suitably affixed and supported in the upright of
the main supporting frame and it provides a pivot for the lever one end of the latter
being extended beyond the horizontal table so that it can be conveniently grasped and
adjusted by the attendant. The inner end of the lever is provided with a short arm l
arranged parallel therewith, and a short distance from the inner end of the lever and
thereby provides an intermediate space in which the band pulley is located, this
arın being connected with the lever by a short transverse arm the said arms and
lever being rigidly secured together or formed of a single piece.
The shaft R is journaled in suitable openings near the inner end of the lever and
the pulley is rigidly secured to the shaft so as to rotate the same by motion from
pulley D which is transmitted by belt pt that encompasses the pulleys D 2 the
crank arm being rotated with the pulley and its shaft to reciprocate the rock
shaft P.
The swinging hand lever is pivoted eccentric to the axis of pulley D so that the
pulley is caused to lie at different distances from the said pulley as for instance
when the lever is elevated as shown in full lines in Figs. 2 and 4* the pulley carried
theroby lies nearer to pulley D and when it is lowered the pulley lies farther from
pulley D.
It will be seen that when the lever and pulley are elevated, the band p will be
tightened so that it will transmit the motion from the pulley D to the pulley and
when the lever and small pulley carried thereby are lowered the band will be slackened
and it will not transmit the motion from one pulley to the other, thereby providing
simple and effective means for instantly throwing the jig-saw mechanism into and out
of use.
The jig saw frame S comprises two horizontal bars s and s' which are
arranged parallel with each other and connected together for simultaneous operation.
One of these bars s is arranged above the table a¹ and the other beneath the same and
the rear ends of the bars are independently pivoted to opposite ends of a post or
standard T. These pivots of the bars are each formed by a pair of conical pointed
regulating screws which work in suitable aligned openings formed in the extremities
of the fixed post and the pointed ends of the sorews bear against the bars at
diametrically opposite points on the same.
This post or standard is arranged at one side of the table a² of the machine and it is
rigidly connected to a bracket lug t of the said table.
The post is made in two sections which are beveled at their meeting ends to form
a lap joint and the said sections are further connected by a dowel pin t¹ which enters the
meeting ends of the sections. The lower bar s¹ of the jig saw frame is connected to the
lower end of the lower section of the post which is rigidly affixed to the bracket lug of

page_text: end has a socket f³ for the reception of the boring bit or tool G held in place by a
binding screw G in a manner similar to that described with reference to my other
construction of machine.
The work to be operated upon by the boring bit or tool is supported upon a sup-
plemental table H which is provided with a vertical flange h which impinges upon the
sides of two of the uprights a. The table is further provided with a depending
arm H slotted longitudinally at * and through this slot passes a threaded bolt or
screw ' which also passes through a similar sloth that aligns with slot h*. This
slot h³ is formed in a vertical upright H³ rigidly affixed to the main supporting frame
and the table H is thus adjustably secured to the main frame to hold the work at
different elevations.
I indicates a sand papering head which may be connected to the mandrel when the
bit G is removed and held in place by screw i¹. The head I comprises a flat disk
which has a hollow boss i in which the end of the mandrel is fitted. The edge of the
disk is inclined or beveled as at 2 so that a binding ring I can be fitted thereon to
clamp the sand or emery paper between the beveled periphery of the disk and the
ring. The said ring is beveled or tapered transversely and in fitting the ring upon
the head or disk the reduced edge of the ring is first fitted on the lower edge of the
beveled disk and the ring is then forced or pushed by hand upon the periphery of the
disk to conceal the periphery of the latter and lie flush with the vertical faces of
the same.
The sand or emery paper may be renewed by merely detaching the ring or
annulus.
The main driving shaft B is driven or operated by a treadle J as in the machine
heretofore described.
The end of the shaft B at the end where the pulley C is connected thereto is
extended beyond the frame A and has a crank disc j affixed thereto.
The latter has a crank pin j¹ to which is connected the upper end of a link the
opposite end of which is connected to one of the side pieces of the treadle. The
opposite side piece of the treadle is connected with the crank shaft by a similar
link which is likewise connected to a crank pin j³ affixed to one of the radial arms
of pulley D.
will now describe the means for rotating the shaft by hand.
A counter shaft K is journaled in fixed bearings k at the upper portion of the main
frame and to this shaft is affixed a sprocket wheel k¹ over which a sprocket chain
passes a similar sprocket wheel being affixed to the shaft B. The counter shaft is
provided with a crank handle K₁ so that said shaft may be rotated by hand. One end
of the counter shaft is extended flush with the side of the machine where the table H
is located and said end has a socket therein in which a pin or arm on the crank handle
is fitted to securely connect the said parts together while permitting them to be readily
disconnected.
The arrangement of the band sawing mechanism is similar to that described with
reference to the other machine that is to say, L is a vertically disposed arm or
standard affixed to one side of table a' and has the arms perforated for the passage of
a vertically adjustable rod m. m² is a binding screw for holding the rod in an adjusted
position.
To the lower end of rod is affixed a guide M which is adjustable with the rod.
The standard L has a stud or shaft n upon which is mounted a belt pulley N. N' is
a band saw which passes over pulleys N D and over a tightener pulley O journaled in
the upper end of a supporting arm o connected to one of the uprights of the frame.
The pulley O is adjustable towards and away from the pulleys N D so that the tension
of the band can be taken up and slackened by means of a regulating screw O' which
works in a suitable aperture in the main frame. This screw also works in a threaded
nut o' on the arm o to adjust the latter and the inner end of the opening in the main
frame is filled by an elastic packing o³ against which the inner end of the screw bears
for the purpose of taking up the expansion and contraction of the saw blade.
It will be seen that the band saw can be readily placed over the pulleys DN by
adjusting the pulley O toward the band pulleys after which the regulating screw is

page_text: is rigidly secured to the top of the table A and when adjusted will be drawn towards
said point of securement and the feed is adjustable vertically through the medium
of a screw rod N³ having an operating handle n which passes through ears n¹ formed
integrally with the vertical portion N3 of the frame N¹.
In the lower depending portion of the vertical part N' of the frame a short shaft &¹
is mounted and upon the end of the shaft, a belt wheel W³ is secured which is
adapted to be engaged by a suitable cross belt w³ passing over the mechanism herein-
before set forth.
In the rear of the wheel W³ a small gear wheel G³ is mounted which meshes with
a larger gear wheel G* mounted upon the outer end of a shaft having bearing in the
outer portion of the frame at one end and in the inner end of the frame N* which is
in position over the table A.
The inner end of the shaft is provided with a cylinders upon which a serrated
feeding disk is mounted which engages with the stock being operated upon in the
line of the saw cut or kerf so that the stock will not be injured or defaced by the
engagement therewith of the disks. The frame N¹ at that point where the shaft s³ is
mounted and passes therethrough is curved and formed with a downward projection
from an elbow formed at this point.
By this means the mechanism is accommodated without any interference of the
parts with each other.
Inside of the gear wheel G³ and pivotally swung on the shaft s¹ is a curved
handle P which has a belt pulley p secured to its lower end which engages with the
belt passing over the large belt wheel W³ and is adapted to tighten said belt as
will be readily understood.
The upper portion of the handle P is provided with a pin p¹ which engages with a
curved ratchet bar P' secured at one end to the frame Ni and by means of which the
belt tightener is held in an adjustable position.
This improved form of feeder is adapted to be used in connection with any style of
wood working machine.
The feeder is adjustable rearwardly as hereinbefore set forth or vertically to and
from the table A to accommodate various thicknesses of stock as will be very readily
understood.
I will now describe the construction of machine illustrated in Figs. 1 to 13ª of the
drawings.
A designates the main supporting frame comprising essentially the vertical uprights
or legs a, upper sills a³, table a¹ and horizontal beams a² secured to the uprights near
their lower ends.
B indicates the main driving shaft journaled in boxes baffixed to two of the
beams a². This shaft carries two large pulleys C and D rigidly affixed thereto. The
pulley C is arranged within the side edges of the table and beneath the same and the
pulley D is arranged at the opposite extremity of the shaft and exterior to the
horizontal table.
F indicates a circular saw and the manner of mounting the same and the means for
operating it are similar to those described with reference to the other construction of
machine hereinbefore described, said saw being mounted on a mandrel F¹ which is
supported in boxes f of the swinging frame E. A draw rod F3 is pivotally connected
at its inner end to the saw mandrel for changing the position of frame E to raise or
lower the saw. The draw rod or iron is held in any desired position by a binding
screw F. The periphery of the saw F is projected through a slot in the table, a',
to adapt the saw to act upon work of different classes held on the table by a gage F'
as in my other machine which gage is adjustable toward and away from the slot f³
and is adapted to be turned at any angle thereto.
The saw mandrel carries a small band pulley g rigidly affixed thereto and arranged
in line with the pulley and said pulleys are connected by a belt g₁ so that the saw
mandrel is positively rotated from shaft B.
One end of the saw mandrel is extended a short distance beyond one edge of
table a¹ and passes through a horizontal slot formed in one of the bars a³ and said

page_text: in sections and the sections connected by screws m¹ so that by turning the screws the
sections of the boxes may be tightened or loosened as desired. The tightening of the
boxes clamps the standard M' while the loosening thereof allows the sliding frame to
be moved to any point desired. This arrangement also allows wear to be taken up by
adjusting the boxes. Under certain conditions I may provide a supplemental set
screw to engage one of the standards and hold the sliding frame at any desired
position.
The cross or transverse bars of the frame have suitable aligned openings or bearings
in which is journaled the shaft of a vertical pulley M³ which is capable of rotation in
a horizontal plane and is driven by belt connections from the main driving shaft.
The upper end of the shaft is extended or projected above the frame and to said upper
end is adjustably secured in any suitable manner, a cutter head carrying cutters of
any desired configuration. An opening a is made in the table through which the
cutters may project when operating upon the work.
The jig saw J is mounted in the manner and operated by the means described
hereinafter with reference to the other construction of my machine, and as shown
plainly in Figs. 2 and 3ª the means employed being precisely similar in both
machines.
Adjacent to the position of the jig saw J an elongated narrow aperture a¹ is formed
in the table A through which the circular saw S' is adapted to play.
Adjacent to this aperture suitable clamp guides or gages A2 may be secured as shown
in Fig. 1 and in connection with the circular saw, a feed mechanism N as shown in
Figs. 4 and 7 is mounted which will be presently described.
The circular saw S* is mounted in connection with a swinging frame I and the shaft
upon which the said saw is mounted is provided with a sprocket wheel encircled by a
chain belt which is run from the main shaft.
The frame I is pivoted upon the shaft S and in its upper end is mounted the
saw-mandrel. The frame I is of such length as to clear the top beam B2 of the
frame B and when the saw is thrown to one side it rests against one of the standards
thereof whereby a steady rest is provided for the saw.
The bearing of the said saw passes above the beam B and is not fixedly retained in
connection therewith.
For varying the position of the frame I to project the edge of the circular saw
above or to lower the same beneath the table, a draw rod "I' is connected to the
frame I, said draw rod extending beyond the main frame B to be grasped by the
operator.
For fixing the saw in its adjusted position, a clamping hook bolt i is provided
which engages with the rod I' in connection with one of the transverse beams of
framework, the said hook bolt being engaged by a winged clamping nut by which the
draw rod may be clamped. 1' is a boring bit held by a screw Is in a socket in the
extended end of the saw mandrel.
On the outer side of the beam B and in position with respect to the rounder is a
peripherally slotted disk B which has slots cut therein equal in width to the diameter
of the openings in the disk of the rounder.
When the said disk of the rounder is turned to a hole therein of the proper
diameter, the disk B is also turned so as to bring the slot therein corresponding with
the hole turned, in position in the disk of the rounder in direct alignment therewith.
When the stop is placed in position with respect to the notch in the rounder it
rests in the slot of the disk B4 and is retained thereby which disc B* acts as a support
therefor while being operated upon and until finished.
Upon one side of the machine adjacent to the circular saw slot in the top of the
table I mount a feed N.
This feed consists essentially of the frame or casting N₁ consisting of a horizontal
portion N which projects over the table A and a vertical portion N situated parallel
with one side of the machine. This feed is adjustable longitudinally by means of a
link connection N* one portion n³ of which is screw threaded and in connection
with the horizontal portion N2 of the feed entire and the other portion n³ of the link N'

page_text: engage with the depending portion of the said table engages with the eye bolt and clamps
the standard upon which the bracket is secured and holds the said table in a raised or
lowered position thereby.
The said table is provided with a hinged bracket d which is adapted to be folded to
one side and under the said table D and the table of itself is provided with hinges
and formed with a drop leaf whereby the several parts forming the said table are
constructed to fold up and thereby take up very little space when not required
for use.
I will now proceed to describe my improved rounding mechanism.
Findicates a rotary head provided with a central opening or aperture w³ and an
enlargement w on its rear side. This head is carried by a hollow shaft V journaled
in suitable bearings, said shaft carrying a belt pulley which is driven from shaft S.
A binding screw, w0¹ serves to securely connect the head F to the shaft, so that it
will rotate therewith, and in its outer face the head is provided with a chamber or
recess which is made circular in form and arranged eccentrically with the axis of
the head.
The indicating disk F¹ is loosely fitted in the chamber so as to lie flush with the
outer side thereof and the disk is pivoted eccentrically to the head so as to be capable
of rotary motion therein independently of any movement of the head.
The indicating disk has a series of circular apertures or openings the centers
of which are arranged equidistant at or near the periphery of the disk, the centers of
said apertures being equidistant from each other and from the center of the disk as
shown. These openings are of different diameters, so that they will accommodate
work of requisite diameter and the apertures are adapted to align with the central
opening or passage in the head and its tubular shaft whereby work fed to the
indicating disk will pass through the opening therein and the shaft and head. The
dial after being adjusted is held in position by a binding screw.
The disk F is also provided with a series of notches w¹ which are adapted to align
with the stop in the main body of the rounder.
These notches lie in a radial line drawn through the centres of the head and the
apertures in the disk and indicate when an aperture properly aligns with the central
opening of the head and the passage of the shaft.
F is a knife or cutter which is attached to and adjusted toward the center of the
head by means of a slot cut in the body of the head and a rib f projecting into
the same which rib is engaged by a screw and clamping nut from the reverse side of
the head.
The cutter may thus be adjusted to act upon work of different diameters.
The indicating disk is adjusted or turned so that the opening therein of a diameter
corresponding to that of the work to be operated upon is in alignment with the central
opening in the head and the passage of the tubular shaft after which the disk is
secured in position by the binding screw before mentioned.
A rod or bar of wood is now fitted in the proper openings in the disk and head and
passed into the tubular shaft and the cutter F is adjusted to the work and power
applied to the shaft to rotate it and the head and cause the cutter to act on and turn
the bar which is fed or moved by hand through the tubular shaft and emerges from
the opposite side of the machine in a finished state.
It will be understood that bars of different sizes can be readily turned and that the
parts can be easily and quickly adjusted for use.
The forming or molding mechanism for shaping stock to any preferred configuration
is constructed as follows:
I employ a frame M secured to which are boxes M¹ which are vertically adjustable
on cylindrical standards M².
The frame M can be readily adjusted in a vertical plane upon the said standards and
retained in its adjusted position by tightening the connection of the boxes to the
frame which will produce a clamping effect in connection with the standards M².
The arrangement and construction of the boxes to effect this purpose is shown more
clearly in the sectional view Fig. 9. As will be seen the tubular boxes M' are made

the jig-saw.
Figs. 11 and 12 are detail views of parts of my improvements.
Fig. 13ª is a vertical sectional view taken longitudinally through the tubular shaft
of the rounding head.
I will first describe the preferred construction of machine illustrated in Figs. 1 to 9
in which A indicates the table of the machine which is supported by a suitable frame-
work B constructed with cross beams which are arranged in such a manner as to
accommodate the reception of the mechanism to be mounted under the table.
On two beams B¹ in the lower portion of the framework B, the main shaft S is
mounted which carries the band wheel W at one end thereof situated on the outer
side of the beam B¹ at this point.
On the opposite end of the said shaft. S and on the inner side of the beam B¹ adjacent
thereto, a band wheel W₁ is mounted and on the outer end of the said shaft at this
point a face plate or disk S' is mounted.
Secured to one of the spokes of the band wheel W and also eccentrically mounted
in connection with the face plate S¹ are rods R which at their lower ends are connected
to the treadle T.
To the rear upper portion of the framework and of the table A, a goose-neck G is
secured which projects over the table and has a band wheel W' which is mounted upon
a short shaft secured to one side of the goose neck G.
The forward portion of the goose neck G is formed with two arms g having apertured
collars formed at their outer ends in which a vertical standard G is secured to the
lower end of which an adjustable saw guide G2 is attached.
This adjustable saw-guide G2 consists essentially of an angle plate g¹ having a
slotted vertically apertured strip g³ secured on the face thereof and adjustable in con-
nection with said angular plate g¹ for slightly adjusting the position of the saw S²
when necessary with relation to the hole through which it passes in table A.
In the rear of the frame B adjacent to the point of securement of the goose-neck G,
a tightener is mounted which is adapted to be shoved rearwardly from the frame and
when the band-saw S' is mounted on the band wheels W and W' it is also passed
around the said tightener and through the medium of which the required tension is
exerted thereupon.
In the rear portion of the frame B, a hollow shaft C is mounted adjacent to the
side to which the goose neck G is secured, the said hollow shaft C extending across
the entire width of the machine.
In each end of this hollow shaft C, short shafts c are inserted which are adapted to
receive handles c¹ and are secured in the shaft c by means of set screw c³.
The shaft C is constructed hollow as just described for the reception and adjustability
in its ends of the short shafts c to attain lightness of construction and at the same
time strength and durability.
Upon the central portion of said hollow shaft Ca sprocket wheel C¹ is secured over
which a chain belt is adapted to pass and which engages with a sprocket wheel S³
mounted on the main shaft S and through the medium of this construction this portion
of the machine may be operated by hand power. Adjacent to the boring side of the
machine an adjustable boring table D is mounted having a standard secured thereto
said standard D¹ being provided with suitable slotted collars secured to the same which
slide upon a cylindrical standard D³ of the frame B.
An
eye bolt d³ is mounted on the standard D³ and a clamping nut D' adapted to

Improvements in Wood Working Machines for Sawing, Moulding,
Turning, and Boring, and in Feed Motions for the same and
other Wood Working Machines.
I EDGAR WYVILL SNEDEKER, of Jamesburg Middlesex County State of New
Jersey, in the United States of America, Gentleman, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to an improvement in wood working machines and relates to
that class which combines several mechanisms in one machine adapted to be operated
by foot power and consisting in the construction and arrangement of the parts of the
same which will be more fully set forth hereinafter and particularly pointed out in
the claims.
a
The object of my invention is to provide a wood working machine combining
band saw, jig-saw, molder, circular saw and boring attachment together with mechanism
for turning square or angular stock into circular form.
I have shown in the accompanying drawings and will hereinafter describe two
machines, differing however only in certain details of construction and arrangements
of parts, the different mechanisms or devices for performing the various classes of
work hereinabove set forth, being embodied in each machine.
In the accompanying drawings
Fig. 1 is a perspective view of the preferred construction of wood working
machine.
Fig. 2 is a front elevation thereof.
Fig. 3 is a rear elevation of the same.
Fig. 4 is a side elevation of the boring side of the machine.
Fig. 5 is a detail elevation of the adjustable table used in connection with the boring
mechanism.
Fig. 6 is a detail view in elevation and section of the rounder mechanism.
Fig. 7 is an elevation of my improved form of feeding mechanism.
Fig. 8 is a detail view of a portion of said mechanism.

of the clamping boxes.
Fig 1 ia a fon plan view of a wodified construction of machine.

page_text: position by a binding nut X². The outer face of the support ✗ is inclined transversely
as shown in Fig. 8 and the cutter assumes this inclined position.
The operation of this mechanism is the same as that described herein before.
The table at of the main frame has a movable section 3 at the side thereof
immediately above the saw mandrel as shown clearly in Figs. 1ª, 3*, 4ª and 6ª and the
outer edge of this section 3 is hinged to the frame so that said section can be elevated
to expose the saw mandrel beneath the table.
An emery wheel of any approved pattern is adapted to be rigidly affixed to the
extended end of the mandrel F1 after the rotary saw has been removed therefrom
to adapt the machine to perform classes of work other than those hereinbefore
described.
I do not desire to confine myself to the exact details of construction and form
and proportions of parts herein shown and described, as I am aware that changes
therein can be made without departing from the spirit of iny invention. The belt
which encompasses the sprocket wheel or pulley on the main driving and counter
shafts can he readily detached and placed over the pulley C on the driving shaft and
the pulley on the shaft R of the jig-sawing machine thereby effecting the saving of
one belt.
Of course it will be understood that the belt of one mechanism is removed and
another substituted therefor when the different mechanisms are to be employed.
.
t.
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
1. In a wood working machine the combination of the hollow sleeve or shaft, (
extending transversely across the machine, with the short shafts c adjustably mounted
in connection with said sleeve or shaft C, the handles c' adjustably connected to the
short shaft, c, and the sprocket wheel C¹ on the sleeve or shaft C and chain belt (2
adapted to be connected to the sprocket wheel C, and also to the main shaft of the
machine whereby hand or foot power may be employed for operating the parts as may
be desired, as described with reference to Figs. 1 to 9 of the drawings.
2. In a wood working machine the standards M' the moulder fraine' M and the
sectional boxes M¹ encircling the standards' and having the sections connected by
screws whereby when the screws are tightened-the boxes are brought closer together
to produce a clamping effect and clamp the boxes at any point of the standards as set
forth with reference to Figs. 1 to 4 and 9 of the drawings.
3. In combination with the main shaft S of the swinging frame I, the circular saw S*
mounted in the upper end of said frame above the beam B as herein set forth, the
draw rod connected to the upper part of the frame I and the clamping device i
whereby when the saw is not in use and in a position of rest it is thrown back and
supported on the top portion of the beam B and when drawn into position for use is
permanently held by the device i clamping the draw rod I¹; substantially as described
with reference to Figs. 1 to 9:
