The machine constructed according to our invention consists of two principal
portions one portion being employed for inserting one end of each of the dowels
employed into one edge of a board or piece of wood, the other portion of the
machine being employed to press the boards or pieces of wood together so that the
dowels previously inserted each by one end into one of the boards or pieces of wood
will be forced into the adjoining piece of wood The machine constructed according
to our invention is also provided with apparatus by means of which a mark may
be made so that the boards or pieces of wood may be cut to the width required
To each board or piece of wood to which we may have occasion to hereinafter
refer, we shall refer as the board and in those cases in which more than one board

arriving against a plate y³ secured to the bracket y by means of a bolt and nut-The
arms 10 are so placed upon the shaft 5 that such arms 10 shall at certain times as
will be hereinafter described act against the ends 12ª of the rods 12-Formed in the
plate is an opening or recess 15 seen more clearly in Fig 5 which shows the plate z
detached
When motive power is transmitted to the shaft d by placing the strap f¹ upon the
fast pulley motion will by means of the wheels g, h shaft, and wheels 2, m be trans-
mitted to the sheft n which wall be rotated in the direction indicated by the arrow c—

page_text: The rotation of the cam s will cause the end g¹ of the lever q to be raised and lowered
thereby causing the jaw u² to be moved alternately towards and away from the
surface w¹ of the cross-frame or table w -The cam 9 acting upon the bowl 8 upon the
lever 7 will cause the end 7* of such lever 7 to be raised and lowered, thereby causing
the arms 10 to be turned alternately in the direction indicated by the arrow D und in
a direction opposite to that indicated by the arrow D
One of the dowels 17 to be inserted into the board or boards is shown by Fig 6
Such dowel 17 is formed of a cylindrical piece of metal formed pointed at its onds-
A number of such dowels 17 are placed in the hopper as shown in Fig 3
In Figs 3 and 4 a dowel 17 is shown in position ready for being forced into
board The attendant places the edge of the board 18 in which the dowel 17 is to be
inserted upon the surface w¹ of the cross-frame or table w is shewn in Fig 6 and
when the jaw u³ is in its highest position pushes the board 18 in the direction indicated
by the arrow E until its edge 18ª arrives against the front of the bracket
The pushing of the board 18 will push bick the dowel 17 and rod 12 until the
end of the dowel 17 is level with the front of the bracket y and will thereby cause the
end 12 of the rod 12 to arrive against the surface 10" of the arm 10-The edge 18°
of the board 18 when being pushed against the bracket y will hive caused such
edge 18" to ct against the plate 3* and turn the lever 3 upon the stud y' in the
direction indicated by the arrow F-The turning of the lever 3 as aforesaid will by
causing the face of the lever 3 to act upon the projecting part formed upon the
plate z, have slidden the plate 2 in a direction opposite to that indicated by the
arrow A and brought the opening or recess 15 beneath the dowels contained in
the hopper thereby permitting a dowel 17 to enter the opening or recess 15-Thic
rotation of the cams will raise the end q¹ of the lever and cause the board 18 to be
gripped or held between the jaw u' and surface w¹-A further rotation of the shaft n
will cause the cam 9 to raise the end 7 of the arm 7 and thereby cause the arm 10 to
push the rod 12 in the direction indicated by the arrow B-The rod 12 acting ig unst
the dowel 17 will force it forward into the edge 18° of the board 18 and afterwards i
further rotation of the cams will allow the end q' of the lever q to descend so that the
Jaw will be rused clear of the board 18 which may then be withdrawn-The
amount of motion given to the rod 12 by the arm 10 must be so proportioned to the
length of the dowels 17 that such dowels 17 will be forced into the board the requnod
distance-When the movement of the jaw u is arrested by the jaw u³ pressing
upon the board a further raising of the end g¹ of the lever q will cxtend the spring v-
The removal of the board 18 from the front of the bracket y will allow the sping 1 to
draw the plate z and turn the lever 3 into the position in which such plate ind
lever 3 re shown in Fig 3-Formed in the front of the bracket y is spice 01
pissage 19 the bottom of which is indicated by the dotted lines 20-The front of the
space or pissige 19 is closed by the plate y²-Through the plate y' and leading to the
plate 3 is in opening 21 When the opening or recess 15 in the plate rives
above the top of the space or passage 19 the dowel 17 which had previously passed
from the hopper into the space or passage 19 will fall down the opening 21-The
curved bottom of the space or passage 19 and the opening 21 through the plate y will
guide the dowel 17 so that one end of the dowel 17 will be against the end of the
rod 12 and that the other end of such dowel 17 will rest in the notch 4 in the plate 3ª
The end of the rod 12 which acts against the dowel 17 is formed with iconical
recess 12b as indicated in Fig 7 which is a view shewing the rod 12-The point of
the dowel 17 passing into the recess 12" is prevented from been injured
The machine shown in the drawings is provided with apparitus for inserting four
dowels into the edge of the board at one operation but if a greater number of dowels
are required to be inserted more hoppers may be employed or the board is again
placed beneath the jaws u² as previously described and more dowels are inserted and
this operation may be repeated until as many dowels is may be requied have been
inserted-If fewer than four dowels are required to be inserted in the edge of
board one or more of the plates 2 18 or are drawn forward and held in that position by
.

page_text: a peg or pegs or any suitable means so that the movement of the corresponding
lever 3 or levers 3 when a board is placed in position for having dowels inserted will
not actuate the plate z or plates z drawn forward
The parts hereinbefore described are those employed for inserting one end of each
of the dowels into the edges of boards to be subsequently pressed together by the
apparatus which we are now about to describe

at times caused to gear into or engage with ratchet teeth formed on the bevel
wheels 38 39 Mounted fast upon the shaft 44 is a cam 45 the circumference
of which acts against a bowl 46" upon the end of an arm 46 fast upon the shift 31-
Secured to the end-frames a and b are brackets 47 supported in which and free to be
turned therein is a shaft 48-Mounted fast upon the shift 48 are arms 49 each of
which is connected by means of a spring 50 to an arm 51 loose upon the shaft 48-
The arms 49 are each provided with projecting parts 492 and the arms 51 are
each provided with projecting parts 51-The springs 50 cause the projecting
parts 51 upon the arms 51 to be drawn against the projecting parts 19ª, upon
the arms 49-Fast upon the shaft 48 is sector 52 the circumference of which
18 concentric with the shaft 48 The sector 52 is shown upon a larger scale in
Figs 8 and 9-Mounted loose upon the shaft 48 are arms 53 to the ends of
which is jointed by a pin 53* a curved arm 54 which curved arm 54 18 Jointed
to links 55 which hnks 55 are Jointed to a lever 56 capable of being turned at

page_text: rods 64 which are at their other ends jointed to arms 65 mounted fast upon
shaft 66 capable of being turned in brackets 67 secured to the end-frames a 6-To
the arms 65 is secured a bar 68 the lower edge of which is provided with a rib or
flange 68 Resting upon the frame 26 is a bar 69 such bar 69 being retained upon
the frame 26 by the arms 26" formed on the frame 26
When number of boards are desired to be "dowelled" together one of such
boards in which dowels have been inserted as previously described is placed upon the
bar 69 so that the dowels are in the upper edge of such board as indicated by dotted
lines in Fig 1 and another board 70° is placed upon the ends of the dowels protruding
from the board 70 the dowels in the board 70 being placed at the top-Another
board 70 which is without dowels is placed upon the dowels protruding from the
board 70 The combined width of the boards is such that when they are joined they
will somewhat exceed the width required-We will for convenience assume that the
width of the boards when united is to be three feet
To
The teeth. 29° are withdrawn from the teeth 24 by the handle 29* being turned
and the frame 26 is moved upon the brackets 24 until the top of the bar 69 is opposite
to the three foot number on the graduated scale 24" when the frame 26 is secured in
such position by the teeth 29b being again placed in gear with the teeth 24"
provide for cases in which the boards when dowelled together are of a width in which
a fraction of an inch occurs we provide the bar 69 at each end with a series of
steps 69 which by the bar 69 being moved endwise may be caused to rest on the
frame 26 thereby enabling the bar 69 to be rused distance less than the distance
between two of the teeth 24-We prefer to make the teeth 24ª one inch apart and
to make the height of each of the steps 69ª a quarter of an inch-The teeth 24* and
the teeth 29 and the graduated scale 24° upon the brackets 24 enable the bar 69 to
be readily adjusted in position to suit the various widths of the boards to be dowelled
together The graduated scale 24' upon the brackets 24 enables the frame 26 to be
readily adjusted into the position required Mounted loosely upon the shaft 44 is a
cam 71 upon which are two projections 72, 73 between which is situate a finger 74
formed upon boss fast with the shaft 44-The cam 71 and the parts immediately
connected therewith are shown more clearly and upon a larger scale in Figs 10
and 11 which show such cum 71 and parts detached-Secured to the end-frame a is a
stud 75 upon which and capable of being turned thereon is a lever 76 provided with
a bowl or roller 76-To the lever 76 is secured one end of a spring 77 the other
end of which is secured to a stud projecting from the cross-frame 22-To one side
of the cm 71 are attached two melines 78 and 79 which it times act against bowl
or roller 80 upon one end of lever 81 capable of being turned upon a stud 82*
secured to the end-frame a-To the end 81 of the lever 81 is secured the fork 36
which embraces the collar 35-Capable of being turned in bosses formed in brackets
secured to the end-frame a 15 a short shaft 82 fast upon one end of which is in irm 83
provided with fork the ends of which embrace a collar 84 capable of being shidden
longitudinally upon the shaft 33 The collar 84 is prevented from being turned upon
the shaft 33 by a hey and groove by means of which it is connected to the shaft 33-
Fast upon the shaft 82 is a bricket 85 to which is jointed by means of a pin an arm 86
provided with projecting parts 87, 88 which are situate at opposite sides of the
cam 71-The projecting parts 87, 88 are respectively provided with pegs 87" 88"
which are at times alternately acted upon by inclines 89, 90 the inclines 89, 90 being
situate at opposite sides of the cum 71-91 is a short shaft capable of being turned
in bosses formed on a bracket 92 secured to the cross frame 22-Fast upon one end
of the shaft 91 is an arm 93 and fast upon the other end of the shaft 91 is an arm 94
to which is jointed one end of a rod 95 the other end of which is jointed to a lever 96
capable of being turned upon a stud fixed to the end-frame a-To the lever 96 19
Jointed one end of a rod 97 the other end of which is Jointed to the lever 37 previously
referred to
When the boards to be dowelled together are placed upon the bar 69 as previously
described the attend int by means of his foot turns the arm 93 in the direction
indicated by the arrow & thereby placing the collar 35 in gear- with the bevel-

page_text: wheel 39 by means of which rotary motion is imparted to the worm 42 and thereby
causing the wheel 43 and shaft 44 to be turned in the direction indicated by the
arrow H
The turning of the shaft 44 in the direction indicated by the
arrow H will carry the higher part of the cɩm 63 clear of the bowl or roller 62" and
the lever 62 will be allowed to move in the direction indicated by the arrow J and
cause the end 60° of the lever 60 to be free and allow the links 55 to draw the curved
arm 54 towards the sector 52 thereby causing the shoe 54 to bind iguinst the
circumference of the sector 52-The rotation of the shaft a will cause by means of
the cam 58 the end 56 of the lever 56 to be alternately raised and lowered-The
raising and lowering of the end 56% of the lever 56 will by means of the link 5
curved arm 54 and arms 53 cause the shoe 54ª to be oscillated beneath the sector 52
and when the shoe 54* is being moved in the direction indicated by the arrow K
the sector 52 will also be carried in the same direction-Such movement of the
sector 52 will by means of the shaft 48 arms 49, 51 rods 64 and arms 65 cause
the bar 68 to be turned a short distance in the direction indicated by the arrow L
and as the bowl 62b allows the end 60% of the bell-crank lever 60 to rem un free the
bir 68 will continue to be forced by the cam 58 still further in the direction indicated
by the arrow L-The forcing of the bar 68 in the direction indicated by the arrow L
will cause the boards 70, 70, 70° to be pressed together-The portions of the dowels
projecting from the boards 70, 70° will be forced into the boards 70%, 70 respectively
So soon as the boards 70, 70° 70° are pressed together and no further descent of
the bar 68 is possible the springs 50 will yield so that the lever 56 may be raised by
the cam 58 without the machine bung broken or struned The tuning of the
shaft 44 as previously described will cause the cam 71 to be rotated by means of the
finger 74 in the direction indicated by the arrow H until the part 71° of the cum 71
is beneath the bowl or roller 76-So soon as the part 71 of the cam 71 airives
bene ith the bowl 76* the spring 77 drawing the bowl 76° towards the shaft 44 will
cause the cam 71 to be quickly turned upon the shaft 44 until the bowl or roller 76*
has arrived in the recess 71ª as shewn in Figs 10 and 11-The quick turning of the
cam 71 will have caused the incline 78 to act upon the bowl or roller 80 so as to
turn the lever 81 in the direction indicated by the arrow N and by means of the
fork 36 cause the teeth upon the coll ir 35 to be free of the teeth of either of the bevel-
wheels 38 and 39 thereby arresting the rotation of the worm 42 and shaft 44-The
shoe 54* will continue to actuate the sector 52 until the arm 93 is moved in the
direction opposite to that indicated by the arrow G-When the boards are forced
sufficiently close together the attendant by means of his foot turns the level 93 in
the direction opposite to that indicated by the irrow G-This movement places the
collar 35 in gear with the bevel-wheel 88 thereby causing the shaft 44, finger 74 and
cam 71 to turn in the direction opposite to that indicated by the arrow H
quick turning of the cam 71 but in the opposite direction caused by the bowl or
roller 76ª being drawn in the recess 71ª will bring one of the inclines 89 or 90 against
one of the pegs 87° or 88" on the projections 87 and 88 and thereby turn the arın 86
in the direction indicated by the arrow P or in the opposite direction as the case may
be-The movement of the bracket 85 in the direction indicated by the arrow P will
by causing the arm 83 provided with a fork to be turned in the duection indicated
by the arrow Qbring into action certain parts to be herein ifter referred to-When
the incline 90 comes in contact with the peg 88* the arın 86 will be moved in the
direction opposite to that indicated by the arrow P and the teeth on the collar 84
will be in gear with the teeth of the bevel-wheel 111 which sets in motion the bevel-
wheel 110, shaft 109 bevel wheels 107, 108 and the carriage 103 carrying the rod of
blacklead or any suitable marking material as will be hereinafter described―lf on
the other hand the incline 89 comes in contact with the peg 87* the arm 86 will
be moved in the direction indicated by the arrow P and the teeth of the collar 84
will be in gear with the teeth of the bevel-wheel 112 and set in motion in the
reverse direction the shaft 109 and the parts hereinafter mentioned as connected
therewith
The
The turning of the shaft 44 in the direction opposite to that indicated by the

page_text: arrow H will cause the cam 63 to also turn in the same direction and the bowl 62ª
will again support the arm 60 and thereby carry the shoe 54ª clear of the sector 52
and allow the counterbalance weight 100 upon the arm fast upon the shaft 48 to raise
the arms 65 into the position in which they are indicated in the drawing-The shaft 44
will also at the same time turn the cam 71 by means of the finger 74 in a direction
opposite to that indicated by the arrow H until the part 71ª of the cam 71 arrives
beneath the bowl or roller 76 when the cam 71 will be turned quickly by the action
of the spring 77 until the bowl or roller 76ª rests in the hollow 71ª of the cam 71-
Such quick turning of the cum 71 will have caused the incline 79 to act against the
bowl or roller 80 on the lever 81 and cause the teeth on the collar 35 to be moved into
a position midway between the teeth on the bevel-wheels 38, 39 so that neither will be
any longer operated upon
At such times as the boards 70, 70" 70" are being pressed together by the arms 65
the higher part of the cam 45 will by acting against the bowl or roller 46° cause the
springs 32 to be pressed against the boards 70, 70, 70° so that such boards will be
prevented from bulging outwards while being pressed together
After the boards have been pressed together by the bar 68 a line will by means of
the hereafter described portion of our invention be marked upon the board 70b so
that the boards after being dowelled together may be cut to the width required-Fast
upon the cross-frame or table ware brickets 101 which support a rod 102-Mounted
upon the rod 102 is carriage 103 shown detached and upon a larger scile in Figs 12,
13, and 14 which carriage 103 while being capable of being slidden longitudinally upon
the rod 102 is prevented from being turned thereon by a finger 103" which projects
into a groove w² extending lengthwise of the cross-frame w -To the cross-frame w are
secured studs upon which and free to be turned thereon are pulleys 104, 105 106 is
band or cord which after being passed around the pulleys 104, 105 is secured at its
ends to the carriage 103 Fast with the pulley 105 is a bevel-wheel 107 which gears
into bevel-wheel-108 fast upon a shaft 109 carried in bearings in which it is free to
be revolved Fast upon the shaft 109 is a bevel-wheel 110 which gears into bevel-
wheels 111, 112 loose upon the shaft 33-Mounted upon studs are bell-crank-
levers 114, 115-The bell-crank-levers 114 115 are formed with inclined portions 114*,
115 respectively-The bell-crank-lever 114 15 jointed to one end of a rod 116 the
other end of which rod 116 is jointed to the bell-crank-lever 115-Ton stud secured
to the rod 116 is Jointed one end of a link 117 the other end of which is jointed by
means of a stud to the bell-crank-lever 98 previously referred to-To the cirrige 103
is secured a stud 118 upon which and free to be turned thereon is mounted a
bracket 119 The sud bracket 119 is provided with a projecting portion 119 formed
with a flattened surface 119' against which presses a spring 120-Through the
brachet 119 is formed a slot in which is pliced a rod 121 of "black lead" or other
suitable marking material -122 is a finger capable of being turned upon a pin-A
spring secured to the bracket 119 presses the end of the finger 122 against the
rod 121 of "black lead or other suitable making material and thus holds it in the
bracket 119
When the incline 89 previously referred to has turned the fork on the arm 83 so as
to cause the teeth of the collar 84 to gear with the teeth upon the bevel-wheel 112
rotary motion will be imparted to the bevel-wheel 110, shaft 109 bevel-wheels 108, 107
and pulley 105 the rotation of which will cause the band or cord 106 to traverse the
carriage 103 in the direction indicated by the arrow M-As the rod 121 of "black
lend" or other suitable marking material is traversed across the board 70 a line will
be marked on the said board-The carriage 103 will be traversed in the direction
indicated by the arrow M until the projecting part 103 arrives against the inclined
portion 114 upon the bell-crank-lever 114 and turns the bell-crank-lever 114 in the
direction indicated by the arrow R when the turning of the bell-crank-lever 114 will
by means of the rod 116 and link 117 turn the bell-crank-lever 98 in the direction
indicated by the arrow S until the bell-cranh lever 98 to which the spring 99 is con-
nected has been turned past the "vertical" when the spring 99 will turn the bell-crank-
lever 98 rapidly in the direction indicated by the arrow S and cause the end of the

page_text: slot in the rod 97 to turn the arm 86 in the direction indicated by the arrow Y unti
the projecting part 87 with the peg 87° arrives against the side of the cam 71-The
turning of the arm 86 will allow the teeth of the collar 84 to be clear of the teeth
upon the bevel-wheel 111 and stop the movement of the carriage 103-When the
boards forming another set have been pressed together in a manner similar to that
above described the cam 71 will by the incline 89 acting against the peg 87" cause the
band 106 to be traversed in a direction opposite to that indicated by the arrow M and
the rod 121 of "black lead" or other suitable marking material will in its passage
from T to U in a similar manner mark the boards-Upon the projecting part 103°
arriving agunst the inclined portion 115" on the bell-crank-lever 115 the rod 116 will
be moved in the direction opposite to that indicated by the arrow M and by means of
the bell-cranh-lever 98, spring 99 rod 97, arm 86 and collar 84 stop the revolution of
the shaft 109 so that the motion of the carriage 103 will cease-The spring 120 and
flittened surface 119° allow the bracket 119 to be moved to one side or the other
thereby enabling the rod 121 of "black lead" or other suitable marking miteriil to 1
make a mark upon the uneven surface of the board and also prevent the rod 121 of
"black lead or other suitable marking material from being broken or injured
"
Although we have above referred to three boards 70, 70° 70° as being pressed
together it will be and we would have it, understood that the number of boards which
may be pressed together at one operation will depend upon the width of such boards
and the capacity of the machine

tion and in what manner the same is to be performed we declare that what we
claim is
