slightly forward toward their inner ends,
and commonly connected thereat to the rear
end of a main rod 34, which is extended for-
wardly adjacent the center of the axle, and
5 may be connected to any customary brake
lever employed. The main rod may be in-
clined toward one side or the other of the
chassis if desired, and if considerable incli-
nation is necessary, the difference in lateral
10 position may be compensated for by the use
of the usual counter shaft and arm. It
being customary in the late types of cars to
dispose the control levers centrally of the
vehicle, there will not be any difficulty on
15 this account and the rod 34 may be con-
nected directly to the hand lever. For the
support of the rods 33 and 34, a device 36
is secured upon the differential housing by
which the rod 33 at one side is slidably held.
20 If desired, an extension may be formed on
the member 36 at the rear, with an outer
extremity turned to one side as at 37, and a
spring 38 coengaged between this extremity
and the inner ends of the rods 33. By this
25 means the brake will be returned to dis-
engaged position positively, when the hand
lever is disengaged or freed for releasing
movement, and by forming a limiting stop
39 for the engaging rod, the parts will be
30 held against rattling.
The construction described and shown
makes the brake easily accessible, the exten-
sion 15 serving as a protecting casing for the
brake, so that the imid, sand and stones can-
35 not easily get into the space between the
ends of the band, and also the device is pro-
tected against mnhld or slush becoming
packed and frozen between the band ends
or in the path of the lever and impeding or
40 preventing action of the brake. The rods
33 may be connected to the levers by suitable
pins 40. which may be secured by cotter pins
for quick removal, after which the removal
of two bolts -11 holding the extension 15 in
45 place will allow removal of the extension
piece, and the operative parts will be ex-
Io)sed to view and easily accessible for ad-
justment or repair. The location of the
band connections at the upper side of the
50 drum also facilitates access to the parts.
It will be apparent that the lever con-
stritctioi at 27 and 28 and the connections
between the lever and band ends are of a
character which may be readily applied in.
55 various situations other than that illus-
trated, and would be useful in clutches,
planetary transmissions, and other devices,
so that I regard the scope of my invention
as including such applications as indicated.
60 I have illustrated in Figs. 5 and 6 a pre-ferred form of connection between the levers
27, which consists in leading rods 33' there-
from to a large lever 42, having the same
form as the levers 27, as regards the disk
portion, and having concentrically spaced a5
apertures 43 therearound, in two of which
the inner ends of the rods 33' are secured as
at 44. This large lever is secured as at 45
to the upper end of a spring staff 46, having
an intermediate helix 47 formed therein an 70
its upper part cranked as shown. The lower
end is formed with an eye engaged with the
usual bolt and nut at 48, used to hold the
differential housing together. From the
outer end of the lever the main brake rod 49 75
is extended. It will be seen that by the use
of this lever it may be connected to allow
direct connection in the most efficient way
with a brake lever at either side of the
chassis, as indicated in dotted lines, and the so
mounting of the lever permits' it to swing
and thus act as an equalizer between the op-
posed brakes.
What is claimed:
1. In a device of the class described com- 85
prising two rotating brake drum elements,
oppositely moving brake.elements for each
drum, a lever adjacent each drum oscillable
in a plane parallel to the axis of the drum,
said levers having principal arms movable 90
toward each other for braking action, a con-
nection between the levers yieldable to
lateral force applied thereto, eccentric con-
nections between each lever and each brake
element adjacent respective drums, and an 95
operating rod engaged with the said connec-
tions between the levers centrally of the con-
nections, said levers and rods being all op-
erative nearly or quite in a common plane.
2. A device of the class described com- 101
prising a drum, a frame piece thereadja-
cent, a band encircling the drum, an anchor-
age means therefor, said band having rela-
tively movable ends, an extension piece on
the frame piece having a flange concentric 105
with the drmn and having longitudinal slots
therein alined with the drum, blocks on the
band ends having lugs slidable in the slots,
said extension piece having a horizontal slot
therein, a lever having a disk portion at its 110
inner end engaged oscillably in the slot, and -
eccentric connections between the disk and
said blocks.
In testimony whereof I affix my signature
in presence of two witnesses.
