How to Lace a Belt 
The Service of a Lacing Does Not Depend Solely Upon the Size of the Rawhide 
M ANY make a mistake in thinking 
that the heavier a lacing is made 
with rawhide the more durable it will 
be. This leads them to make the lacing 
so thick and clumsy that the belt is 
strained in going around pulleys, caus¬ 
ing the lace to wear out in a short time 
and probably the belt to be torn be¬ 
tween the holes. A good lacing is as 
nearly as possible similar in thickness 
to the rest of the belt, so that it passes 
over the pulleys without shock or jar. 
Preparing the Belt Ends 
For all types of lacings the belt ends 
should be cut off at right angles, 
not by guess, but 
by the aid of a 
square. For the types 
of straight lacing 
this is sufficient, but 
If a hinged lace ( 
is to be put in, 
then the upper and 
lower edges of the 
belt ends should be 
beveled. This will 
prevent the sharp 
edges from cutting 
the lacings.

No. 1 and the other end of the lacing 
down through hole No. 14. 
From hole No. 1 work to the left and 
then back, going through the following 
holes in the order listed: 2-3-4-5-6-7-8- 
9-10-11-12-13 and stop, coming up 
through 14. 
From hole No. 2 work to the right 
through the following holes in the or¬ 
der listed: 14-15-16-17-18-19-20-21-22- 
23-24-25-26, and finish up through hole 
27. The finished lace is shown in

Placing the Holes 
The arrangement 
of the holes will de¬ 
pend upon the type 
of lacing desired, 
the width of the 
belt, and also upon 
the personal prefer¬ 
ence of the individ¬ 
ual doing the work. 
The various types 
of lacings may be 
used on leather, 
rubber or canvas 
belts. As a general 
rule the holes should 
be placed farther 
back from the ends 
on canvas and rubber 
belts than on leather belts. 
Making the Holes 
For leather belts the holes 
are best made with a hol¬ 
low punch, one having an 
oval shape preferred, and if 
used the long diameter of 
the hole should be parallel 
to the sides of the belt. 
The size should be such 
that the lacing will fill the 
holes, but will not pull in 
so tightly as to tear the 
belt. For canvas belts, or 
rubber-covered cotton 
belts, the holes should be 
made with an awl and 
not with a hollow punch, 
as the punch will cut off 
many strands of the cloth 
and thus unnecesarily 
weaken the belt. The tine 
of an old pitchfork will 
make a very good awl for 
this purpose and the oval 
shape will be found con¬ 
venient. When using an 
awl, work it back and 
forth sideways when pass¬ 
ing through the belt, thus making a 
hole by forcing apart the fibers in¬ 
stead of cutting them. 
Types of Rawhide Lacings 
The two most important types of 
lacings are (a) the Double Straight 
Lace and (b) the Single Hinge Lace. 
For leather belts the straight lace 
is generally used unless the belt is 
to be run over very small pulleys 
or to be bent backward over idler 
pulleys, in which cases the hinge lace 
will last much longer than the 
straight. 
For canvas or rubber belting the 
hinge lace is best as it is more flexi¬ 
ble and therefore less liable to pull 
out at the holes than is the straight 
lace. 
How to Make the Lacings 
With this type all lacings on the 
pulley side of the belt must run parallel 
with the sides of the belt. See Fig. 3. 
Holding the pulley side of the belt 
up (refer to the diagram) pass one 
end of the lacing down through hole

it should be remembered that the lacing 
is never passed from a hole in one 
belt end to another hole in the same 
belt end. Also, when passing from one 
belt end to the other the lacing is never 
carried straight across, but is always 
passed between the belt ends. 
Start at the middle and, holding the 
pulley side of the belt up, proceed as 
follows: 
Pass one end of the lacing down 
through hole No. 1—pass the other end 
down between the belt ends and up 
through hole No. 14. 
Work first to the left edge with the 
lacing end which was passed down 
through hole No. 1. Pass this lacing 
end through the following holes in the 
order listed, remembering to always 
pass between the belt ends when pass¬ 
ing from one belt end to the other, 
from No. 1-2-3-2-5-4-5-6-7-6. 
Now work to the right edge of the 
belt with the lacing end which passes 
up through hole No. 14, passing 
through the following holes in the fol¬ 
lowing order from No. 14 to No. 1, 
then No. 16-15-16-17-18-17-20-21-20. 
One end now finishes, passing down 
through hole No. 6, and the other end 
passes up through hole No. 20. The 
finished lacing is shown in Fig. 3. 
Securing the # Ends 
The ends may be secured in several 
ways—with some types of lacing the 
free ends are merely tied together. 
Another common way is to punch a 
small hole for the lacing end. The end 
is passed through this hole and drawn 
tight, then this end is passed back 
through this same hole and drawn up 
tight. The doubled lacing, passing 
through the hole, jams and is securely 
held. Any excess 
lacing is cut off. 
Ends finished in this 
manner may be seen 
in Figs. 2 and 3. 
Size of Pulleys 
The use of the 
proper-sized pulleys 
has much to do with 
the efficient opera¬ 
tion of belt-driven 
machinery. How to 
select the proper 
sizes is not as dif¬ 
ficult as some per¬ 
sons think. 
In every case, one 
knows, or can find 
out, two facts about 
one of the pulleys— 
its diameter and its 
speed. One also 
knows at least one 
fact about the other 
pulley—either how 
fast it should run 
or how large it ac¬ 
tually is. An ex¬ 
ample shows how to 
figure the unknown 
quantity better than 
explanation.. 
Take an engine running 
at 600 revolutions a min¬ 
ute. The engine pulley is 
twelve inches in diameter. 
You desire to run a feed 
grinder at 900 revolu¬ 
tions a minute. What size 
pulley should you get? 
You know the engine 
pulley’s speed is 600 revo¬ 
lutions and its diameter 
is 12 inches. You know 
but one thing about the 
grinder pulley, its speed, 
which is 900. How can 
you find the diameter? 
Multiply together the 
two things that you know 
about one pulley and di¬ 
vide by what you know 
about the other pulley. 
In the above example, 
600 multiplied by 12 
makes 7,200. Dividing 
this by 900 gives 8. 
Therefore, an eight-inch 
pulley is needed on the 
feed grinder. 
The result will not al¬ 
ways come out even, and 
as pulleys are sold only 
in certain sizes it is necessary to select 
the next larger or smaller pulley. 
When computing the diameter of a 
driven pulley, select the next size 
smaller. When computing the diameter 
of a driver pulley, select the next size 
larger. 
Cooperatives Must Not Fail 
(Continued from page 66) » 
the same condition; they are all fight¬ 
ing for volume of business, rendering- 
less efficient service because they lack 
it. And the farms are paying the bill. 
Economic necessity demands that 
farmers go back to fundamentals in 
the purchase of farm supplies. If they 
will be guided by the unbiased conclu¬ 
sions drawn from tests at their experi¬ 
ment stations; if they will secure their 
credit from banks instead of from the 
local dealers; if they will combine with 
this efficiency of purchase orderly mar¬ 
keting of farm supplies, then there is 
great hope for American agriculture 
and the welfare of the entire country.
