ll Claims. (Cl. 213-50)
This invention relates to improvements in cen
tering means for draft gears of railway cars.
One object of the invention is to provide a’
simple and efficient centering means for cylin
5 ders or housings of friction draft gears of rail
way cars, which may be readily attached to the
sills without the use of rivets or other similar
securing means.
’
whereby the clips are securely clamped in posi
tion.
Other objects of the invention will more clearly
appear from the description and claims herein
after following.
.
In the drawings forming a part of this speci
?cation, Figure l is a part plan and part hori
zontal, longitudinal; sectional view of a portion
Another object of the invention is to provide
of a draft rigging of a railway car, showing my
10 a centering means of the character set forth in
improvements in connection therewith, the usual
the preceding paragraph, which is especially de
signed for application to draft sills having open
ings therein, the openings being made use of in
connection with securing the centering means in
cover plate for the draft sills being omitted in
said view. Figure 2 is a longitudinal, vertical,
sectional View corresponding substantially to the
15 position on said sills.
A further object of the invention is to provide
a centering means for cylinders or housings of
draft gears, which centering means is in the
form of a pair of metal clips clamped to the op
20 posed draft sills of a railway car.
A more speci?c object of the invention is to
provide centering means in the form of metal
clips having bendable portions by which the
clips may be clamped to the draft sills of a rail
25 way car, thereby facilitating attachment of the
centering means to the sills, the clips being es
pecially designed for application to sills having
openings therethrough, each clip being in the
form of a metal member having a loop portion
30 and a pair of arms extending from said loop
portion, the loop portion being disposed on the
inner side of the sill to which it is attached, and
overlapping the web of the sill at said opening,
the arms extending through said opening, .and
the extremities of said arms being bent outward
1y into engagement with the outer side of the
web of the sill to lock the clip in ?xed relation
with the inner side of the loop thereof in posi
tion to center and guide the cylinder or housing
40 of the draft gear.
A still further object of the invention is to pro
vide a novel blank from which a centering clip
may be readily manufactured by simple bending
and forming operations.
Yet another object of the invention is to pro
vide a simple and efficient method of manufac
turing centering clips from sheet material, by
cutting and shaping operations, whereby a com
plete clip is produced which may be readily

ure 1.
Figure 4 is a plan view of a blank from
which the improved clip is formed. Figure 5 is
an edge elevational view of the finished clip be
fore application to the draft sill of the rigging.
Figure 6 is a rear elevational view of the clip
shown in Figure 5, looking from right to left in
said last-named ?gure. Figures 7, 8 and 9 are 25
exterior elevational views of a portion of one of
the draft sills of a railway car, illustrating three
consecutive steps in the method of applying the
improved clip to the sill. Figure 10 is a vertical,
sectional View corresponding to the line lil—|ll
in Figure 9. Figure 11 is a view similar to Fig
ure 9, showing the clip clamped in position on
the sill, said view being partly broken away.
In said drawings, ill-l9 indicate channel
shaped draft sills of a railway draft rigging, hav
ing the usual front and rear stop lugs H-—il
secured to the inner sides of the vertical webs
i2-l2 thereof. The sills iii-40 are of the type
which have openings therethrough, said openings
being indicated by l3—i3. The inner end of the 40
usual drawbar is indicated by It, and a yoke i5
is connected thereto in the usual manner. A front
follower l6 and a shock absorbing mechanism
are contained in the yoke. The shock absorbing
mechanism illustrated is of a well-known de
sign, comprising a friction casing or housing Ill,
friction shoes l8——l8-—i8, a wedge l9 and spring
resistance means (not shown) within the casing.

in the manner of the usual rear follower.
As
shown in Figure 3, the friction casing I1 is sup
ported on the lower arm of the yoke I5 and the
yoke, in turn, is supported on a saddle plate 2|
secured to the bottom ?anges of the sills III-I0.
My improved centering means comprises a pair
of metal clips A—A secured to the draft sills
I0-I 0. Each clip A comprises a partial loop por
tion 30, disposed on the inner side of the corre
10 sponding sill I0, and top and bottom arms 3I and
32 extending from said loop portion through the
opening l3 of the web I2 of the sill I0. The outer
end of the arm 3| terminates in spaced ?ngers
33-33, which are bent upwardly against the outer
15 face of the web I2 of the sill in clamping relation
therewith. The extremity 34 of the bottom arm
32 is bent downwardly against the outer side of
the web I2 of said sill, therebyproviding a hook
member which is in clamping relation with the
20 sill. The loop section 30 of each clip includes a
vertical section 35 and curved upper and lower sec
tions 36-36 connecting the vertical section 35 to
the arms 3I and.32. As most clearly shown in
Figures 2, 3 and 11, the loop section 30 of each clip
25 extends beyond the top and bottom walls of the
opening I3 of the corresponding sill in overlapping
relation with the metal of the Web of said sill. As
will be evident, when the clips A-A are clamped
in position by the bent extremities of the arms 3I
and 32, as shown in Figure 3, the sections of the
loops 30-30, which overlap the webs I2-I 2 of the
sills at said openings I 3-I3 of the sills, will be
clamped tightly against the inner sides of the
webs.
The parts‘ are so proportioned that the
.35 vertical sections 35-35 of the loops 30-30 of the
clips A—A are spaced apart the required distance
to properly center and guide the casing I‘! of the
friction gear therebetween, the ?at outer surfaces
of the sections 35-35 being opposed to the ver
40 tical walls 20-20 of the casing.
My improved clips are formed from ?at blanks
cut from bar material, one of said blanks being
shown in Figure 4, said blank being indicated by
31. The blank 3'I.is in the form of an elongated,
45 ?at plate having a forked upper end portion, pro
viding spaced ?ngers 33-33. The ?ngers 33-33
are preferably formed by cutting away the metal
of the blank 31, as indicated at 38.
The ?nished clip, before application to the
draft sill, is shown in Figures 5 and 6. As shown
in said ?gures, the clip comprises a loop 30 and
partially formed upper and lower arms I3I and
I32 extending therefrom. The loop 30 includes
a vertical section 35 and the curved upper and
hereinbefore described.
The curved sections 36-36 connect the section 35
to said arms I3I and I32. The‘lower arm I32 is in
the form of a hook member I34 of the shape
shown in Figure 5. The upper arm I3! is in the
60 form of a forked member comprising laterally
55 lower sections 36-36
spaced ?ngers I33-I33, one of said ?ngers being
disposed at right angles and the other parallel to
the section 35 of the loop of said clip, as shown in
Figure 5. The clip illustrated in Figures 5 and 6
65 is formed by bending the blank shown in Figure 4
to shape. The shaping of the blank into form
is preferably performedin a single operation, by
bending the blank about a suitable mandrel by
means of shaping dies.
The operationof applying and securing the clip,
shown in Figures 5 and 6, to the draft sill is per
formed as follows: The clip is placed on the inner
side of the sill III in thelposition shown in Figure
F1, so that the extremity of the hook I34 and the
75 projecting ?nger I33 at the right-hand side of
said clip, as viewed in said ?gure, will register
with and may freely enter the elongated opening
I3 of said sill. The ?nger I33 and the hook I34
are then pushed through the opening I3 to such
an extent that the upper and lower portions of
the loop 30 will engage with and bear on the inner
face of the web I2 of the sill. The clip is then
rotated from the position shown in Figure '7,
through that shown in Figure 8, to the position
shown in Figures9 and 10. The ?ngers I33-I33
and the hook I34 are then bent to form the clamp
ing ?ngers 33-33 and the clamping extremity
.34 of the arms 3I and 32, respectively, as herein
‘be'fore described and as illustrated in Figures 1,
2, 3 and 11, thereby clamping the clip in ?xed 15
position on the sill. In bending the parts of the
clip from the shape shown in Figures 9 and 10 to
that shown in Figures 1, 2, 3 and 11, the arm I33,
which is at right angles to the section 35 of the
loop-30, is bent upwardly against the outer side of 20
the web I2 of the sill above the opening I3, the
extremity of the hook I34 is bent downwardly
against said web below said opening, and the
?nger I33, which is parallel to said section 35 of
the loop 30, is bent outwardly and then upwardly .25
against the Web so as to engage and lie ?atly
against the same above said opening.
In this connection, it is pointed out that the
application of the clip to the sill is greatly facili
tated by providing the partially formed clip, as I30
shown in Figures 5 and 6, having two spaced
?ngers at the upper end, one of which is left
parallel to the section 35 and the other of which
is disposed at right angles to said section, in that
the projecting portions of the arms of the clip;
may be readily entered through the opening I3 of
the draft sill I0 and the clip turned to a position
where it will be temporarily held, through en
gagement of the hooked lower end with the metal
of the sill, during the ?nal bending and clamping 40
operation.
From the preceding description taken in con
nection with the drawings, it will be evident that
I have provided exceedingly simple centering
means for the casings of friction shock absorbers 45
of railway draft riggings, which centering means
may be economically manufactured and readily
applied to the draft sills of the railway car with
out the use of rivetsor similar securing means,
simple bending operations only being required to
clamp the clip tightly in position.
I have ‘herein shown and described what I now
consider the preferred manner of carrying. out my
invention, butthe same is merely illustrative and
