machine. Printing heads I2, each carrying a
printing block I3, are provided for printing a
strip of goods I5, advanced intermittently over
a table I6, and supported upon the frame I5.
The heads I2 are secured upon head slides I8
located on opposite sides of the frame and are
slidable vertically in guides 20. VThe slides I8
each have a roller 2l which is- engaged by a cam
22 for lifting the heads I2. The cams 22 are
10 secured upon opposite ends of shafts 23, mounted
upon the frame IIJ. The shafts 23 each have a
bevel gear Wheel 24 secured thereon and rotated
by means of suitable gearing 21, driven by a main
shaft 25, in the usual manner.
When it is desired to omit the printing op

eration of any head, the head is held in the ele
vated position by latches 26, which engage pro
jections 28, secured upon the slides I8. There
are two latches 26 for each head. A shaft 30 is
20 rotatably mounted upon the frame I0, and the
latches are rigidly secured upon the opposite ends
of said shaft which project beyond the sides of
When the solenoid 55 is energized, the hook
36, on the lever 31, will be moved into engage
ment with the pin 40, and the bearing arm 35
will be moved with the cam arm 32. The bear
ing arm 35 is held in an adjusted position for
insuring the engagement of the hook 36 with the
pin 43 by an eccentric stop sleeve 53, which is
secured upon a cross shaft 54, rotatably mounted
in the frame IB. A guide plate 55, shown in Fig.
2, is secured upon the bearing arm 35 and pro
jects along one face of the cam arm 32 for guid
ing the parts in proper relation.
Each hook lever 31 is moved by a solenoid 50,
which latter is connected in an Yelectric circuit 56
including a switch 58 adapted for closing said 15
circuit and energizing the solenoid 58 for lock
ing the hook 35 with the pin 40, thus engaging
the latch 26 with the projection 28 for holding
the printing head I2 out of operation.

33 without moving the bearing arm 35, and the
40 latches 26 will not engage the projections 28,
thus allowing the head to be operated by the
cams 22 for printing upon the goods.
A clamp head 45, see Fig. 2, is rigidly secured
upon the shaft 36, carrying the latches. A plate
45 spring 43 is secured in the clamp head 45 and
the free end` of the spring 46 is adapted to be
engaged by a pin 41, secured on the bearing arm
35. When the hook 36 is engaged with the pin
4i! the bearing arm 35 will be moved with the
50 cam arm 32, and the pin 41, on the bearing arm
35, will move the spring 46, which latter will
rotate the shaft 3D and swing the latches 26 into
contact with guide plates 49, and when the head
is moved adjacent to its highest position, the
55 spring 43 will force the latches into engagement
with the projections 28 and hold the printing
heads in the elevated position, during one com
plete revolution of the cams 22 and 33. At the
completion of the revolution the cams 22 will
60 lift the head slides I8 sufliciently to release the
latches 26 from the projections 28, so that weight
43, shown in Fig. 2, secured upon the shaft 30,
will tend to turn the latter and move the latches
away from the projections 28, unless the hook
65 3E is still held in engagement with the pin 40,
as hereinafter described, in which case the head
I2 will be held in the elevated position by the
latches 25 during another revolution of the cams
22 and 33.
The hook 33 is moved into engagement with the
70
pin 46 by the action of a solenoid 50, secured to
the bearing arm 35. The solenoid 50 may be of
any well known construction.
The movable ar
mature 5I of the solenoid is pivotally connected
75 to the Weighted arm 39 of the lever 31.
18 from the main shaft 25 for advancing the belt
l6I in timed relation with the advancement of
the goods I5 through the machine.
The bearing frame 16 is supported upon the
frame I6 by brackets 13, shown in Fig. 1.v A ta
ble 3€) is mounted upon the frame 10 and also
secured to the frame I0 by plates SI. The table 45
Sil forms a support for tracks 82 on which the
straight run of the belt 6| is supported. Verti
cal bearing plates 84 and 85 are secured upon the
table 85 and extend along opposite sides of the
belt 6I for a distance equal to about one-half the 60
distance between the wheels 54 and 65, on which
the belt is mounted. Said plates 84 and 85 form
supports for the opposite ends of a series of
transverse shafts 86, positioned above the belt so
that the latter may pass below said shafts and 55
operate a switch 58 located upon each shaft 86,
for controlling the operation of the printing
heads.
There is a switch 58 and a solenoid 50 included
in each circuit 56 for controlling and operating 60
the latches 26 for each printing head I2. Said
shafts 86 are detachably secured in the bearing
plate 84 by thumb screws 81, shown in Figs. 3
and 4.
Handles 88 are secured upon the shafts
36 for quickly removing the shafts when chang 65
ing the position of the switches.
The chains 63 of the belt 6i are formed of links
Si! pivoted together by pins 3i, as shown in Figs.
3 to 5. The links 96 have extension brackets 32
thereon to which the ends of the transverse plates
62 are secured by bolts 93 and said plates 62 are
supported by the brackets 92.
The transverse plates 52 of the belt extend
parallel to each other and form a fiat surface
throughout the straight run of the belt. Said
3
2,104,894
plates 62 are preferably formed of aluminum
strips each 5/8” in width.
` »i
’I'he entire length of the belt Sl is formed of
the hinged sections, or plates 62, each occupying
%"`throughout the length of the belt. Each sec
tion of the belt corresponds to an 18” section of
the goods to be printed. The length of the belt
is equal to a multiple of 64 sections or plates G2,
when the goods are to be cut into strips each
10 96’ long, and containing 64 sections and adapted
to be received in a drying rack of that length. If
the printing machine is to be used in connection
with a drying rack of a different size, then the
number of plates '52 forming the belt will be
15 varied accordingly.
Each plate 62 is formed with slots 95 to pro
vide means for detachably mounting cam blocks
96 upon the belt, for operating the switches 58.
Upon the under surface of each cam block 96 is
20 a double end plate spring 9i, shown in Fig. 4,
adapted to enter a slot 95 of a plate 52 and en
gage the plate 9? for detachably securing the
cam block 95 upon a plate 52.
A cam block 9€ may be secured in any one of
25 the several slots 95, which latter are arranged at
given intervals throughout the length of each
transverse plate 62. The cam blocks 96 will be
carried by the belt in columns for operating suc~
ccssively the different switches 53, which switches
30 are positioned immediately above a particular
column of the belt for controlling certain print
ing heads l2 for printing starting border sections
of the rugs, or heads for printing ñeld sections,
or heads for printing finishing borders, or double
35 borders, or center designs of rugs. By shifting
the cam blocks 95 from one column of the belt to
another column any desired order may be fol«
lowed for printing rugs of different sizes.
The switches 58, which are actuated by the cam
40 blocks 95, are each operated by an arm 9S, one
end of which arm is rigidly secured upon a sleeve
99, which is loosely mounted upon a shaft 85.
The sleeve 99 projects beyond one side of the arm
98 and forms a bearing for a clamp block lßü,
which latter is adjustably secured in any desired
radial position on the sleeve 2S by a set-screw
IUI.
The clamp block mi) has an extension plate H32
thereon, which plate is provided with a spring
50 clip H13 for holding a mercury tube switch H35,
of any well known construction. Said mercury
tube switch forms part of the switch 58.
The free end of the arm 98 is provided with a
roller H35 which normally rests upon the flat surn
55 face of the belt plates E2, as shown in Fig. 5,
and positions the switch tube 155 at an angle in
clined to the top surface of the belt til, so that
the mercury in the tube will form an electrical
connection between the contact points lill and
60 Hi8 located within the tube |05 and included in
the circuit 55. When a cam block 95 is moved
by the belt into engagement with the roller ii’âë,
the arm Sil and the tube IE5 will be tilted t0 a po
sition to cause the mercury to flow away from
65
the contact points it? and §08 and open the
circuit 56.
l
The arm 98 and the clamp block Iâil are posi
tioned longitudinally upon the shaft 85 by spac
70 ing sleeves lila, which extend endwise and abut
against the opposite bearing plates 84 and S5.
By removing a shaft SÉ and rearranging the
sleeves |69 upon the shaft Bâ the roller iiliì of
any switch may be positioned to be engaged by
75 the cam blocks 96 located in any of the different
columns through which the cam blocks are
` moved by the belt.
"Jïfhe longitudinal adjustment of the switches
58 andthe rollers |536 upon the shafts 85 is only
necessary when rearranging the printing order
of the heads l2.
To permit the switch tubes
i535 to tilt without interfering with each other,
the diiîerent switch arms S8 are provided With
right and left hand sleeves 99, whereby the plates
lilâ carrying said tubes m5 can be staggered 10
throughout the series of shafts 8E and thus allow
the shaftstc be placed as closely together as pos
sible, so that a relatively long surface of the
control belt El will be visible to the operator be
yond the series of shafts 85.
Each switch 5B comprises a mercury tube
switch lûîi and controls an electric circuit 5i?,
which circuit also includes a solenoid 5B, which
in turn controls a latch operating device 3l lo~
cated adjacent to each printing head E2.
When a mercury tube ESS, forming a switch
58, is tilted by the weight of the arm 98, to a
position in which the roller |96 rests upon a
plate 62 of the belt ël, the circuit 5E will be
closed, the solenoid 5E) will be energized and the
latch operating device will be moved to engage
the latch 25 with the projection 28 on the head
slide 48 and hold the printing head l2 out of
action. When the roller Hit is upon a cam block
95 the switch tube lüñ will be tilted to a position 30
to open the circuit
and the latch 26 will re~
main out of engagement with the projection 28,
the printing head will be free to be moved
down into printing Contact with the goods.
The printing blocks i3, on the heads l2, each 35
print a section of the goods i8” long and the strip
of goods l5 is moved 18” for each complete
revolution of the head operating cams 22. Each
plate E2 of the control belt is of a size propor
tional to an 18'l section of the goods and said belt
is advanced at a speed proportional to the travel
of the goods.
The strip of goods i5 to be printed is of great
length and it is desirable to cut the original long
strip of goods into shorter strips, of given lengths,
so that each shorter strip will exactly ñt a drying
rack of a given size. If the rack is 96' long the
strip when cut should contain sixty-four, 18"
rug sections, and to avoid any waste of material
the rugs must be completed in sizes to exactly 50
cover the 96' strip. The control belt 6l must al
ways be of a relative length to contain 64 sec
tions, or plates 52, or a multiple of 64 plates.
rl‘he shafts B6 and switches 58 extend over only
about one-half the length of the top flat surface
of the belt 6l, the remaining portion of the flat
surface of the belt is exposed and presents to
the operator a conventional picture, or minia
ture representation of the rugs before the goods
are printed. The exposed surface of the belt 6|, 60
with the cam blocks @t arranged thereon, repre
sents the arrangement of the rugs to be printed,
and said surface is visible before the cam blocks
pass below the switches 58 for controlling the
printing heads. The exposed area of the belt Si
is of sufñcient length to give the operator ample
time to correct mistakes and to change the sizes
of the rugs before the goods are printed.
When a defective spot occurs in the goods the
operator may readily remove a cam block 9G 70
from a section, or plate £52 of the belt, which plate
corresponds to the 18" section of the goods where
the defective spot occurs. In some cases where
large defective spots occur, two or more cam
blocks 96 may be removed. The absence of a cam
75
4
2,104,894c
block from the belt will cause the switch 5d to
close the circuit 56 so that the latoh'operating
device will latch the printing head associated
therewith out of operation.
‘It will be understood that each section, or plate
62, represents 18" of the goods. If a plate E52
does not carry `a cam block 96, the corresponding
18” section of the goods will not be printed
upon.
The cam blocks S6 represent the sections
of the goods to be printed, and may be rearranged
to change the rug sizes. The positions of the cam
blocks 96 in the different columns upon the belt
determine the type of printing heads to operate
for printing upon the goods.
15
There may be ñve or more printing heads for
printing diiîerent colors upon border sections of
the rugs, and five or more heads for printing
different colors on iield sections. Each series of
printing heads is controlled by a series of switches
,20 53 arranged in rows upon the series of shafts 36.
Each row of switches extends parallel with and
immediately above a column of the Slots 95
formed in the belt plates 62.
The cam blocks Q6 positioned in the column of
25 slotsindicated in Fig. 3 by the letter A are for
operating switches 58 for controlling border type
automatically repeat the printing order in which
the printing heads are to be operated. it is only
necessary to change the arrangement of the
blocks 9S when it is required to omit the printing
of defective spots occurring upon the goods, or
when it is desired to change the sizes oi the rugs
to be printed.
'
A manually operated snap-switch H6 is pro- '
vided in each circuit 5t, and said snap-switch is
arranged for opening the circuit when a printing
head is not to be used and is permanently locked
out of action by a hand operated latch well known 15
in the art and not shown in the drawings.
The operation of my invention is as follows:
The cams 22 reciprocate the printing heads con*
tinuously except when they are held in the ele
vated position Yand out of action by the latches
2&5. The cams 22 are set so that they will operate
the heads for printing upon every other sec
tion of the goods. The goods are then advanced
by the machine until the intermediate sections
are positioned below the heads to be printed
printing heads, for printing either single borders,
upon, in the usual manner.
The cam arms 32 of the latch operating de
or double borders, as previously determined
vices 3i are loosely mounted on the shafts 3
cam blocks in

The
for operating
30 switches for controlling heads for printing ñeld
sections of rugs. The column C is provided for
cam blocks for controlling printing heads, not
shown on the drawings, for printing center ñeld
sections of a dì?îerent design, and the column D is
35 for signal cam blocks HI).
The signal cam blocks Hl) are for operating a
signal switch I l 2'for actuating a signal l i3, shown
in Fig. l. Each signal cam block l! upon the
belt indicates the place where the goods are to
be out ori to form strips of a given length to loe
received in a drying rack of a given size, usually
96’ long.
The sections, or plates 62, of the belt 6I are
numbered 1 to 64, which numbers are not shown
45 on the drawings, said numbers are repeated
throughoutl the length of the belt. A strip of
goods may be started into the machine at any
point. The number on the control belt plate, cor
responding to the starting point of the goods, is
50 noted and a signal cam block Il@ is then placed
upon every sixty-fourth plate throughout the
length of the belt for operating the signal switch
II2 and the signal H3.
The signal switch I I2 is similar to the switches
55 5d, and the switch IIE is included in an electric
circuit H4 including the signal device II3, such
as an electric bell shown in Fig. 1.
The extensive exposed flat surface of the control
belt 5I gives the operator ample'time to change
60 the position of the cam blocks 96 without stopping
the machine. The signal switch cam blocks IIII
indicate to the operator that the strip of goods
is to be cut at a certain point and that the goods
must be finished with a finishing border at that
65 point and a starting border printed immediately
70
block IIU on the belt. After the cam blocks
9G have been properly arranged upon the belt be
tween the Signal cam blocks H6 the belt will
and are moved continuously by the cams 33.
The latches 2S are normally out of engagement 5.*
with the projections 2S of the printing heads.
The hooks 36 are released from the cam arms
3E by the weighted ends> 39 of the hook levers
3l, thus the printing heads may be moved ‘into
printing contact with the goods upon every rev
olution or" the shafts 23.
v
When a circuit 56, including a solenoid 5t of
any latch operating device 3l is closed, the hook
3S will be positioned to engage the cam arm pin
di), so that the arm 32 will move the bearing arm Lii)
35, and theV pin 4'! on the bearing arm will
engage the plate spring dä, which latter will
yieldingly move the latch 25 into the path of l
the projection 28 and hold the head out of action
when the latch is engaged with the projection 26.

printing operations the operator can readilyV upon the next revolution of the cam 22.
When a cam block Q6 is attached to any plate
change the order of the cam blocks 96 upon the
of the belt, a section of the goods represented
belt before they actuate the switches v5t.
The operator by inspecting theadvancing con
by that particular plate will be printed upon by
trol belt ßI may see which cam blocks 9E must be
shifted for changing the sizes of the rugs to com
moved whenever itis desired to prevent the
plete a strip of goods which is to be out oiï ad
75 jacent to the corresponding position of a signal
a head I2.
A cam block dä may be readily re
printing oi'V any i8” section of the goods which
may be defective. The belt 6l is constructed so 75
2,104,894
that the cam blocks 96 will be carried by the
belt in any one of several columns for actuating
a series of switches 58 arranged immediately
above'the different columns. The shafts 85 on
which the switches 58 are mounted are separated
by a distance equal to two plates 62 of the
belt. When a plate t2 does not have a cam
block in a particular column all the switch arm
>rollers §65 which are located over that column
10 will ride upon the flat surface of the belt and
said switches'will be positioned for closing the
circuits 56, thus energizing the solenoids 5E! for
latching the heads l2 but of printing action.
The switches 58 are all mounted in close re
lation to each other so as to leave a large dat
surface of the belt El exposed to View before the
cam blocks are advanced below the switches.
i ie exposed portion of the top surface of the
control belt presents a miniature representation
of the order in which the printing of the suc
cessive sections of the goods will take place, and
the operator may make various changes in the
sizes of the rugs before the printing of the cor
responding sections of the goods takes place.
When a cam block 96 is removed to prevent
the printing of a defective portion of the goods,
the operator'can see which cam blocks must be
shifted from the column of cam blocks which
operate the headsy for printing ñeld sections of
rugs to those for printing border sections, so that
complete rugs will be printed before and after
the defective sections of the goods occur.
Signal cam blocks titl are inserted at given
intervals upon the belt Bl, which blocks H0
show the operator where the strip of goods is
to be out to be placed in certain size drying
racks.
'I'he operator may readily change the
cam blocks 95 which are located upon the belt
adjacent to the signal cam block llt, so that the
last section of the goods will be printed with a
finishing border and the new section of goods
will be printed with a starting border.
When a new piece of goods is started into the
machine the number of the plate of the control
belt is noted and the signal cam blocks IHJ are
attached at intervals throughout the length of
the belt, whereby the signal blocks will indicate
where the goods are to be cut, and the operator
can shift the blocks 96 upon the belt so that each
strip of the goods 96' long will contain finished
rugs of a salable size.
Various changes in the construction and ar
rangement of the parts may be made without
departing from my invention.
