PETER W. AGNELL, OF BIGSPRING, TEXAS.
DRAFT ATTACHMENT FOR RAILWAY-CARS.
SPECIFICATION forming part of Letters Patent No. 743,411, dated November 10, 1903.
Application filed August 10, 1903. Serial No. 168,970. (No model,).'o aUl whonI it may concern:
Be it known that I, PETER W. AGNELL, a
citizen of the United States, residing at Big-
spring, in the county of Howard and State
5 of Texas, have invented new and useful Im-
provements in Draft Attachments for Rail-
way-Cars, of which the followingis a specifi-
cation.
My invention pertains to draft attachments
io for railway-cars; and it consists in the pecul-
iar and advantageous attachment hereinaf-
ter described, and particularly pointed out in
the claims appended.
In the accompanying drawings, forming
15 part of this specification, Figure 1 is a side
elevation, Fig. 2 a plan view partly broken
away, and Fig. 3 a longitudinal central sec-
tion, of the attachment constituting the pre-
ferred embodiment of my invention,the same
20 being shown with the draft-rods connecting
the couplings thereof broken. Fig. 4 is a
transverse section taken in the plane indi-
cated by line 4 4 of. Fig. 2.
Similar letters designate corresponding
25 parts in all of the views of the drawings, re-
ferring to which-
A B are the couplings of my novel attach-
ment. These couplings are similar in con-
struction, and for this reason a detailed de-
30 scription of the coupling B at the right of the
drawings will suffice to impart an understand-
ing of both. Referring therefore to the coup-
ling B, C is the body or draw-bar of the coup-
ling, which is cast in one piece and is de-
, 5 signed to take the place of the draft-timbers.
usually employed. The said body comprises
a longitudinal central portion a of U shape
in cross-section, closed at its inner end by a
transverse wall b and having slots c, d, and e
40 in its side walls, flanges f extending out-
wardly from the upper edges of the U -shaped
or channel portion a and designed for con-
nection to the bottom of a car-body, a bridge-
bar g,connecting the outer ends of the flanges
45 f and resting above the outer end of the por-
tion a, an abutment-h, located in the portion
a at an intermediate point in the length there-
of and having an outwardly-extending flange
i and longitudinal vertical strengthening-ribs
5o j, arranged in the portion a between the wall
b and the abutment h.
- D, E, and F are cross - heads extendingthrough and movable longitudinally of the
body C in the slots c, d, and e, respectively,
thereof. 55
G is a follower arranged in the portion a of
the body at the outer side of the abutment h
and in engagement with the outer edge of the
cross-head D; H, a slide-block movable lon-
gitudinally in the portion a of body C and 60
having a transverse slot snugly receiving the
cross-head E; I, a draw-head abutting at its
inner end against the outer end of the slide-
block H, bearing on a carrier-iron 12 and hav-
ing a transverse slot snugly receiving the 65
cross-head F; J, a-coiled spring arranged in
the body below the flange i and interposed
between .the follower. G and the inner end of
the slide-block H; and K K, links arranged
alongside of and close -to the portion a of 70
the body C and connecting the cross-heads D
and F.
The two couplings are arranged in the re-
lation shown at opposite ends of a car-body,
and their cross-heads are connected through 75
the medium of longitudinal draft-rods L.
With the couplings applied and connected
as above stated it will be observed that when
the draw-head of. either coupling is drawn
outwardly the pull will be placed on the 8o
spring of said coupling through the medium
of the cross-head F, links K, cross-head D,
and follower G, and on the spring of the other
coupling through the medium of the parts
just mentioned, the slide-block H of the first- 85
mentioned coupling, the cross-head E there-
of, the draft-rods L, the cross-head E of said
other coupling, and the slide-block H there-
of. It-follows from this that the attachment
is elastic and at the same time strong and 90
well calculated to withstand the shocks and
strains to which draft attachments are ordi-
narily subjected.
When the draw-head of either coupling is
pressed inwardly, the spring J thereof will 95
serve to cushion the thrust and prevent in
large measure the transmission of shock and
jar to the other parts of the coupling and the
car-body.
The arrangement of the draw - heads, iou
springs, and other working parts of the coup-
lings in the solid castings forming the bodies
or draw-bars C contributes materially to the
strength. and compactness of the attachmentNo. 7'C,411.
