PHILIP V. CONOVER, OF UVALDE, TEXAS.
ELECTRIC CAR-BRAKE.
SPECIFICATION forming part of Lettrs Patent No. 265,023, dated September 26, 1882.
Application filed Algurt 8. 1882. (No model.)To all whom it may concern:
Be it known that I, PHILIP V. CONOYEw, of
Uvalde, in the county of Uvalde and State of
Texas, have invented a new and Improved
5 Electric Car-Brake, of which the following is
a full, clear, and exact description.
The object of my invention is to facilitate
the applying and releasing of car-brakes by
means of electricity.
To The invention consists in a combination,
with a friction-wheel mounted on the car-axle,
of a friction-wheel mounted on a laterally-ad-
justable vertical shaft, provided at its upper
end with a beveled cog-wheel, engaging with
15 a beveled cog-wheeLon a horizontal shaft jour-
naled in the iuder sideof thecar-floor, on which
horizontal shaft is loosely mounted a worm,
which engages with a worm-wheel mounted on
the shaft to which the brake-chainis attached,
2o a hereby when this worm is locked on the shaft
by suitable devices and the shaft is rotated the
brake-chain will be wound on the shaft of the
worm-wheel, and the brakes will be applied.
The invention further consists in a sliding
25 sleeve mounted on the horizontal shaft on the
under side of the car-floor in such a manner
that it can slide on the same and turn with it,
which sleeve is provided with radial arms,
which are pressed against the annular flange
30 at the end of the worm and engage with a stud
on this flange, thereby locking the worm to
this sleeve, which sleeve is connected with a
fork or rod, passing into a helix, whereby
when the circuit of this helix is closed the rod
35 will be drawn into the helix and the clutch-
sleeve will be drawn from the end of the wornm,
which is thus released.
The invention also consists in the combina-
tion, with a cog-wheel on the axle, of a rack
40 adapted.to be pressed against this cog-wheel
by a lever acted upon by a rod passing into a
helix, which rack has its upper end pivoted to
a lever, which is adapted to press the friction-
wheel on the laterally-adjustable shaft against
45 the friction-wheel on the axle; so that the fric-
tion-wheel on the lower end of this laterally-
adjustable shaft will engage with the friction-
wheel on the axle.
Reference is to be had to the accompanying
5o drawings, forming part of this specification,in which similar letters of reference indicate
corresponding parts in all the figures.
Figure 1 is a plan view of the under side of
a car provided with my improved electric car-
brake. Fig. 2 is a longitudinal sectional ele- 55
vation of the same on the line x , Fig. 1. Fig.
3 is a detail cross-sectional elevation of the
same on line y y, Fig. I.
On the car-axle A, which is journaled in the
truck in the usual manner, is mounted a ver- 6o
tical friction-wheel, B. In a hollow standard,
C, projecting from the under side of the car-
floor A', a vertical shaft, C', is held loosely in
such a manner thatit can be moved laterally,
and on the lower end of this shaft a small fric- 65
tion-wheel, D, is rigidly mounted, which can
be pressed against the side of the friction-
wheel B. On the upper end of the shaft C' a
beveled cog-wheel, E, is mounted, which en-
gages with a beveled cog-wheel, E', mounted 7o
on ahorizontal shaft, F,journaled on the under
side of the car-floor A'. A cog-wheel, G, is
rigidly mounted on the car-axle A, preferably
near one end of the same. A -eack-bar, H, is
pivoted at its upper end to the outer end of a 75
lever, 1, which is pivoted in the hollow stand-
ard C, projecting from the under side of the
car-floor, and which lever I has its inner end
provided with a slightly-rounded head, 1',
which rests against a boxing or plate, J, rest- o80
ing against the shaft C'. The lever K, pivoted
to ain arm, K', of the standard C, is provided
at its outer end with a recessed plate, L, fit-
ting against the outer surface of the rack-bar
H, and to its upper end is pivoted a rod, I, 85
which passes through a helix, N, held to the
under side of the car and connected with a
battery. On the horizontal shaft F a worm,
O, is loosely mounted, which engages with a
worm-wheel, P, rigidly mounted on a shaft, 9c
Q, journaled in standards Q', projecting from
the bottom of the car, to which shaft Q the
brake-chain iR is attached. The worlm O is
provided at the end farthest from the car-
axle with an annular flange, O', from which a 93
stud, a, projects. A sleeve, S,is loosely mount-
ed on the shaft F in such a manner that it canl
slide longitudinally on the same, but is ro-
tated with this shaft by a key or spline, s, in-
serted between the sleeve and the shaft. At oo
