JAMES B. GARRETT, OF PITTSBURG, TEXAS.
WAGON-BRAKE.
SPECIFICATION forming part of Letters Patent No. 458,280, dated August 25, 1891.
Application filed May 29, 1891, Serial No, 394,532. (No model,)To all zvhom it may concern:
Be it known that I, JAMES B. GARRETT, a
citizen of the United States, residing at Pitts-
burg, in the county of Camp and State of
5 Texas, have invented certain new and useful
Improvements in Automatically - Operated
Wagon-Brakes; and I do hereby declare the
following to be a full, clear, and exact de-
scriptionof the invention, such as will enable
io others skilled in the art to which it apper-
tains to make and use the same.
My invention relates to automatic brakes
for wagons;- and it consists of certain novel
and useful features herein described and
15 claimed.
Reference is had to the accompanying draw-
ings, wherein the same parts are indicated by
the same letters.
Figure 1 represents a plan view of one
20 form of wagon bed and tongue fitted with my
improved automatic brake, the wagon-body
being removed. Fig. 2 represents a profile
view of the tongue and sliding rod beneath
the same.
25 A andA' represent the axles,the frontaxle
A supporting the bolster B.
C and C' represent the wheels.
D represents the coupling-pole rigidly se-
cured to the rear axle and braced by the
30 braces E. This coupling-pole is pivoted to
the front axle at d, which axle is free to turn
horizontally about the king-bolt d.
F is a lever, which may be either pivoted
to the wagon-bed at e or pivoted to the under
35 side of the wagon-body. This lever carries at
its outer end a brake-shoe f.
F' is a second lever connected to the lever
F by two eyebolts and a link or two of chain,
or otherwise securely coupled thereto. One
40 end of the said lever F' carries the brake-
shoe J, and the other end has a link f3, en-
gaging the rod G. This rod is connected by
a few links of chain II to the rod K, sup-
ported by eyebolts k beneath the tongue N.
45 The said tongue has a cuff i on its tip, in
which the lever L is pivoted at 1. The upper
end of the lever has a hook l' and guard or
snap l2 for engaging and holding the ring m
of the breast-yoke M. The lower end 13 ofthe lever L is connected by the short rod K' 5o
to the long rod K.
O is the tongue-hound, and P the hound
connecting the pole or tongue N to the front
axle A.
Q and Q' are braces to the hounds. 55
The inner end of the tongue N and of the
rod K, and also the chain II, should be as
near the center of the front axle as possible,
so that the rod G should always be practi-
cally in the line of a radius drawn with the 6o
king-bolt as a center, in order that the brakes
may not be automatically applied when turn-
ing short around.
The operation of my device is as follows:
Suppose the team to be reined in for any 65
reason, they will draw back on the breast-
yoke C and pull back the upper end of the
lever L. This will move the rod K forward,
and dragging the chain II and rod G in the
same direction will move the lever F' about 70
its pivotf2 and the lever F about its pivot e,
and will press the brake-shoes f' and f against
the hind wheels C'
In order that the brakes may be promptly
put into action when the team starts ahead 75
again, I provide a spring S of sufficient
strength to ease the brakes should the mov-
ing parts not work smoothly; but this spring
may be omitted. A hand-lever may also be
added to work the brakes by hand. 80
I do not claim any particular form of wagon
bed or tongue, or any particular method of
fastening the brake-levers thereto, or to the
wagon-body, or any form of hand-lever to be
used in conjunction with myautomaticbrakes; 85
but
What I do claim, and desire to secure by
Letters Patent of the United States, is-
In an automatic wagon-brake, the combi-
nation, with the tongue N, having the cuff 90
n, of the lever L, pivoted at 1 in the said
tongue and having the hook l', with means
of closing the same, and the arm l-, the breast-
yoke M,having ring Im, the rod K', connected
to the lower end of the lever L, the rod K, 95
moving in eyebolts k beneath the tongue
and connected to the rod K', the chain H,
connected to the other end of the rod K, the
