Installing
General Plan
The diagram on the preceding page shows the general plan of installa-
tim to be followed, also the dircetion the machino runs
Ready to Operate
Refore shipment, each machine is thoroughly run in, accurately sud-
juated and carefully inspected. This is evidenced by the test sample left in
the machine. Packed by killed hands, they arrive at their destination
ready for service
Caution
Carefully note the threading of the machine when laker from the ship-
ping box. Do not withdraw the threads. 'The operator can use the thread
advantageously by tying the ends and drawing the new thread in the ma-
chine. It will do no harm to torn the machine puller onc or two revolt-
tions, provided it is turned in the indicated direction
Power Tables
In the manufacture of bags for which most of the styles in Classes 1800
and 1000 are designed, the maximum of efficieney can only be seeured by
installing the machines on specially built tables. We are prepared to fur-
nish a bluc print, No. $3822 Q, which will cable a local carpenter to
construct economically a table of the most approved design. An ideal table
for a small factory can be had in our portable individual power lable No.
21871 AL; which is equipped with an clectric motor.
Pulley Diameters
Working diamelers of the varions pullcys arc: Machine pulley, 2½
inches; transmitter driving pulley, 7 inches; transmitter driven pulley,
small come, 8%4 inches, large cone, 5¾ inches. Line shaft pulleys are made
in diameters of 6, 8, 9, 10, 11, 12, 13, 1 and 16 inches.They are 1½ inch
face and If inch bore.

'To find the speed of the sewing machine pulley D (sec illustration)
when the diameters .of pulleys A, B, C, and I and speed of Pulley A are

The Order Department endeavors to send the most suitable diameter line
shaft pulley with each machine. A possible missing factor is the speed of
the customer's line shaft. As the driven pulley on the transmitter is de-
signed with a small and a large cone, two different speeds can be secured
on the sewing machine with a given diameter of line shaft pally. by, ar-
ranging the lat belt accordingly. The formula furnished will be helpful
in deciding which come to use to secure the desired speed
Spacing of Machines
The customary spacing measured from needle to needle is 48 inches,
which is ample to prevent average size bags from being entangled with the
belt of the adjoining machine.View original page 7Page 8 · Read text
Installing
Machine and Transmitter
Set the machine on the table in the approsimate position it is desired
to have it occupy, with its pulley toward the right and the front edge of:
the cloth plate one inch back of and parallel to the front of the table,.
If an iron base plate is included in the equipment, it should be placed
under the machine so that the hole near the center of the base plate reg-
isters with the tapped hole in the bed of the machinc. Directly below the
hole near the center of the base plate, bore a 1 inch hole in the table. Pass
the "T' serew through the hole and fasten the machine to the base plate.
Move the hase plate so that the "I"' screw centers in the bole in the table.
Remove the machine and fasten the base plale to the table.
If an iron base plate is not included in the equipment, bore a it inch
hole directly below the tapped hole in the bed of the machine and fasten
the machine to the table with the thumbscrew provided for the purpose.
To avoid contacl with the opcrator's clothing, the transmitter should be
fastened to the underside of the table as far back as possible and the groove
in the brake pulley should be in line with the groove in the machine pulley.
An excollent plan is to place the transmitter on top of the table so these
two pulley grooves are in line and mark the table under the front right hole
in the transmitter plate. Bore a ¼ inch hole at the mark, or directly in
front of it a sufficient distance to avoid the plale extending beyond the
rearhole edgeand fastenof thethetable.transmitlerPass thewith¼ inchthe bolt,flat headwhichstoveis sufficientholt throughto holdtheit

desired. It is prefcrable to cross the round belt if the rotation of the line
shaft makes it necossary. Measure the length of flat belt required and
join the ends by driving in a malleable iron belt fastener No. 31850 against
the transmitter pulley. See that the teeth are well clinched and that the
fastener conforms to the curvature of the pulley. Tuen the pulleys by hand
and swing the transmitter so the belt runs true. Place 14 inch wood
screws in the three remaining holes in the transmilter plate and securely
tighten the pulley on the line shaft.
Borc one inch holes at the required angle for the round bell and locate
them so that the take-up for the flat belt can be used. 'The dress guard
should be fastened to the wnder side of the table directly in front of the
transmitter pulleya.
Locate the transmitter treadle so its center is directly under the ncedle
with the pitman adjustment and enclosed bearing of the trcadle rest to
the left. Variations in the treadle Incation and its incline can he made to
suit the operator's convenience. The pitman need not necessarily hang in
a vertical position.View original page 8Page 9 · Read text
Installing
Floor Treadle Lifter
Included with some machines is a foor treadle lifter, consisting of a
mall treadle and chain, which connects with a lifter lever attached to the
rear of the machine. Bore a 16 inch hole through the table directly under
the hole in the right end of the lifter lever. Looate the small treadle
directly to the right of the transmitter treadle. Pass the chain through
the holc in the table, connect the upper end with the lifter lever and the
lower end with the small treadle. Adjust the incline of the latter so that
the front end is slightly higher than the transmilter treadle.
Thread Stand
Included with some machines is a thread stand for holding the spooks
or comes in a convenient position while the machine is sewing. It should
he located behind the machine pulley and a short distance to the right.

Oiling
Union Specials, like all precision machinery, are closely fitted, therefore,
it is very important that all bearings are properly lubricated at frequent
intervals. It is reconcoded that these machines be given a thoroughView original page 9Page 10 · Read text

oiling five times a day.Any of the following brands of oil will fill the
requirements:
Viscusity Oil Company's "Vertex"
Vacuum Oil Company' "Gargoyle Mobiloil I'
The Texaco Company's "'exaco Alcaid"
Standard Oil Company's "Polarine Medium?'
The diagram shows the places to be oiled. This sequence once men-
urised can be followed in a surprisingly short time without the possibility
of missing any places. All oiling places can be reached without removing
the cloth plate.
Special allention is direcled to the upper bearing of the needle lever
connecting rod and left end of the ncedle lever where bull valves are located.
They are oiled by pressing the ball with the oil-can spout. Styles 1800 Ad,
1800 AC, 1800 AE, 1800 ACt and 1900 AA are fitted with a signal stop oil
cup for the right main shaft hearing. The flow of oil can be regulated by
turning the knurled portion of the stem. Toming it clockwise redaces the
flow and counter-cluckwise acts the reversc. Care should be taken to arid
turning it ton far in either direction as the signal stop feature will be mulli.
fied.The flow is shat off completely when the top of the stem is toppled
over and resumes in the same volume when the top is returned to a vertical
position. Always discontinue the flow when the machine is not in opera-
ton. Refilling the cup can be accomplished through convenient openings,
which are covered by a plate to keep out the dirt and other foreign sub-
stances.
The transmitter is lubricated with solid oil through a hollow shaft trom
a compression eup, which should be screwed up abont once a week.
be screwed up immediately. Refilling will nol be required oftener than
once a month. No. 3 Arctic Cup Grease, or its cquivalent in consistency,
will fill the requirements.
Cleaning
Accumulated Iint and dust quickly absorb the oil, which makes it neces-
sary to kcep the machine as elean as possible. The cloth plate should be
removed cach day and the machine given a thorongh cleaning. Remove
the lint from the oil holes and feed dog slots.
Threading
Styles 1800 A, 1800 0, 1800 G, 1800 H, 1800 AA, 1800 AC, 1800 ACT,
1900 A, 1900 C, 1900 L and 1900 AA are threaded as shown in the diagram.
Stylc 1900 MI is also threaded as shown in the disgram with the exception
of the looper thread, which is missing. Styles 1800 E, 1800 AE and 1900 C
use two needle threads and one looper thread, which pass into the machine
in substantially the same manner as shown in the diagram. Do not pass
any thread entirely around a tension post. The eyelet, adjacent to the
looper thread take-up, is hinged and its front end can be raised for con-
venience in threading. A thread hook No. 118 is furnished for drawing
the thread under the cloth plateView original page 10Page 11 · Read text
Operating
Setting the Needles
'They have two grooves; a short groove terminating in a spot milled out
just above the eye or extending from the shank to a point about ⅛ inch
above the eye. The opposite side has a long groove extending from the
shank to the eve. Insert the needle as far up into the needle bar as it will
go, with the long groove in front, so that the eye of the needle will be in
line with the dircetion of the stitches. Then tighten the needle clamp nut
or set seiCH.
To Commence Sewing
There should be about two and one-half inches of thread berond the
eves of the needles and looper before commencing to sew.. Carry the threads
to the rear. To start the machine, press the for edge of the treadle. When
the pressure is released, the machine is antomatically stopped.To in~
slantly stop the machine, apply pressure with the heel to the near edge of
the treadle.
Removing the Work
Should it be desirable to remove the work without ring off, turn the
pollcy in the operating direction wntil the needle bar reaches its highest
position.Draw a reasonable quantity of needle thread through the tension,
raise the presser foot, pass a pair of scissors under it and eut the necdle
thread as elose to the upper surtace of the fabric as possible. The work
can be removed by drawing it toward the rear of the cloth plate. In this
manner the eut ends of the ncedle threads will be drawn to the underside
of the material and automstically tied.
Jute Bags double edge folder No. 28153 C is somotimos used for turning back
the two cut edges, This folder is pivoled so that it ean be swung out of
position when the operator uniles selvage edges. It is not ineluded as
standard cquipment with any style.
Bleached Cotton Bags
Though the adjustment of the machine be perfect for other fabrics,
some diffculty may he experienced in properly fooding bags made from
bleached cotton fabric, duc to the filler which it contains, as it tends to
make the fabric adhere to the under side of the presser foot. 'I'his diffeulty
can be easily remedied by the use of some solid lubricant. such as the mix-
ture of equal parts of beeswax and tallow, placed on the upper surface of
the presser fool over the needle hole. In passing through, the thread will
carry suficient lubricant to permit the fabric to pass frecly under the
pressor foot. The same result can be effected by dropping a small quantity
nf oil on the upper surface of the presser foot, or betwen the feed dog and
the presser foot, but this may be objectionable because of the tendency to
soil the work.
Time Savers
If a machine fails to work satisfactorily, though apparently in good
repatr, it is possible that some minor trouble exisls. Fur this reason, delay
may be avoided by acting on the following suggestions:View original page 11Page 12 · Read text
Operating
Time Savers--Continued
(I) Note carefully whether the machine is threaded as instructed,
especially at the tensions. Remove any lint which may have ac-
cumulated.
(2) Examine the needle and note whether it is set with the long
groove directly in front and inserted as far up as possible.
(8) Reroove the needle and mole whether it is straight. The best
possible teat is to roll it on a pertcolly flat surface; the point
should roll true.
(4) Remove all the threads from the machine and carefully rethread
il, as shown in the threading diagram.
(5) Clean and oil the machine thoroughly. Try a new needle.View original page 12Page 15 · Read text
