LEWIS C. CARY, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF TO JULIA
CALDWELL, OF EL PASO, TEXAS.
COMBINED STREET-CAR AND AIR-BRAKE COUPLING.
SPECIFICATION forming part of Letters Patent No. 720,325, dated February 10, 1903.
Application filed November 24, 1902. Serial No. 132,702. (No model.)To all W volm i 7may concern:
Be it known that I, LEWIS C. CARY, of the
city of St. Louis, State of Missouri, have in-
vented certain new and useful Improvements
5 in a Combined Street - Car and Air - Brake
Coupler, of which the following is a full, clear,
and exact description, reference being had to
the accompanying drawings, forming a part
hereof.
to My invention relates to an improved com-
bined street-car and air-brake coupler; and
it consists of the novel construction, combi-
nation, and arrangement of parts hereinafter
shown, described, and claimed.
r5 The object of my invention is to provide anI
automatic combined car and air-brake coup-
ler which shall be especially, adapted for use
upon street-cars.
Figure lis a plan view of a pair of my im-
2 proved automatic couplers in coupled posi-
tion and parts being shown in section. Fig.
2 is a side elevation of same looking in the
direction indicated by the arrow A in Fig. 1
and with some parts removed. Fig. 3 is a
25 sectional plan of one of the heads with parts
removed, the section being taken on line 3 3
of Fig. 4. Fig. 4 is an end view of the heads
shown in Fig. 3 looking in the direction in-
dicated by the arrow B. Fig. 5 is a perspec-
30 tive view, on a reduced scale, of an elongated
detachable draw-bar especially for use in con-
nection. with my improved couplers upon
street-cars.
6 indicates the heads of the couplers, which
35 are exact counterparts of each other and are
adapted to automatically interlock, the left
front half 7 of each head being flared or half-
bell-shaped, and the opposite sides 8 are in
the form of, circular necks. Said circular
40 necks 8 are fitted with washers 9, of rubber
or other material, so that a tight joint will be
made between the end of the neck and the
seat of the opposing head. Said seat is pro-
vided with a washer 10, of rubber or other
45 suitable material, and is adapted to be en-
gaged by the washer 9 of the opposing neck.
Within the heads 6 is an air-passage 11, which
is bifurcated, and one of its branches extends
through the neck 8, and the other branch ex-
50 tends through the seat and its washer 10.The washers 9 and 10 are preferably set in
recesses 12. (See Fig. 3.) The necks 8 are
preferably provided with a tapered guiding-
tube 13, which projects through said washer
9 and extends a distance beyond the project- ;5
ing -end of the neck which supports it.
14 indicates a pipe which communicates
with the air-passage 11 and to which the or-
dinary hose is to be attached in connecting
the coupler to-the train-pipe of the car. 6o
The heads 6 are provided in some cases with
suitable perforated ears 15 for assisting in
suspending and supporting the heads be-
neath the car.
For locking the two heads in a coupled po- 65
sition I provide each head with a hinged lock-
ing-arm 16, which is pivoted at 17 to the rear
end of the head and which extends forwardly
and is curved outwardly. Said arm is also
provided with a shoulder 18 for engaging an 70
angular projection 19 on the opposing bell-
shaped half 7.
20 indicates projecting guides for the said
locking-arms, said guides being preferably
cast integral with said bell-shaped half. 75
21 indicates a stop projecting from the
head into the path of each of the said locking-
arms to limit the inward movement of same.
(See Fig. 3, in which the said locking-arm is
shown at the limit of its inward movement 8o
and in its normal position.) Said locking-
arms are held in normal position by means
of suitable springs 22. These springs are
preferably. formed of wire and are coiled
about the pivot 17, as shown clearly in Fig. 85
2,-and the ends of the wire are inserted in
apertures 23, formed in said pivot to prevent
said ends from turning. Said pivot 17 is held
against turning by being squared or angular,
as indicated by dotted lines at 24 in Fig. 2 in 9o
the manner customary in common rail-bolts.
The spring 22 has a U-shaped body, which
is curved outwardly and forwardly and rests
in forcible contact with the outer surface of
the adjacent locking-arm 16. 95
The heads 6,owing to the construction above
described, are interchangeable as well as in-
terlocking. The heads 6 are also-provided on
their tops and bottoms with duplicate inter-
changeable and interlocking automatic coup- Too
