erally grooved roller 21, the latter being
adapted for travel upon the wall of the
runway 18 in the inner saddle plate 15, the
peripheral groove in the roller conforming
5 to the contour of said wall of the runway-
18, thus it being seen that the clevis 19 is
free for movement and the roller 21 mini-
mizes friction in the 'movement of the swin-
gletree relative to the clevis as will be ob-
10 vious.
Fitted over the inner saddle plate 15 is an
outer saddle or covering plate 22 which is
formed intermediate thereof in the top and
bottom portions of the same with outwardly
15 offset panels 23 constituting clearance spaces
24 for the limbs of the clevis 19 which travel
in said spaces 24 on swinging movement of
the bar or beam 10; the front rounded edge
25 of said outer saddle or cover plate 22 is,
20 spaced from the inner saddle plate 15 and
interposed therebetween are filling blocks
26 which are held in place by brads or other
like fasteners 27 driven therethrough and
into the bar or beam 10 as is clearly shown
25 in Fig. 2 of the drawing, thus increasing the
runway 18 for the roller 21 of the clevis 19.
The outer and inner saddle plates 22 and
15 are held secure in assembled relation
upon the bar or beam 10 through the me-
30 dium of fasteners 28 which are passed trans-
versely through said plates and the bar or
beam, while the top panel 23 of the outer
saddle plate 22 has formed therein an oil
hole 29 for the introduction of oil onto the
35 stud journal 20 for the roller to enable lu-
brication 'thereof.
In the use of the swingletree, should the
traces be engaged with the connectors or
attaching devices 14 at the ends of the bar
40 or beam 10 so that one trace will be longer
relative to the other, the swingletree will
automatically adjust itself accordingly to
the load for equalizing the pull upon the
draft animal at both sides of the center line
45 of draft. The beam or bar 10 can. swing
to the proper angle with the clevis 19 dis-
posed in alinement with the center of draft,
it being understood of course that the clevis
19 is connected with the load in any ordi-
50 nary well known manner.
From the foregoing it is thought that the
construction and manner of operation of the
swingletree will be clearly understood and
therefore a more extended 'explanation has
55 been omitted.
It is contemplated that within the scopeof the invention the structural features
thereof can be employed with doubletrees
with equal advantages.
What is claimed is:- 61
1. A draft appliance of the character de-
scribed comprising a swinging member hav-
ing trace-attaching devices at its ends, a
clevis loosely connected with the member, a
saddle carried by the member and having a 6
concave runway for the clevis to traverse, a
covering saddle plate for the first-named
saddle, and a roller in the clevis and con-
tacting with the wall of the runway.
2. A draft appliance of the character de- 7
scribed comprising a swinging member hav-
ing trace-attaching devices at its ends, a clevis
loosely connected with the member, a saddle
carried by the member and having a concave
runway for the clevis to traverse, a covering 7
saddle plate for the first-named saddle, and
a roller in the.clevis and contacting with the
wall of the runway, said covering saddle
plate having offset medial portions to form
clearance spaces for the clevis in its move- 8
ments.
3. A draft appliance of the character de-
scribed comprising a swinging member hav-
ing trace-attaching devices at its ends, a
clevis loosely connected with the member, .a 8
saddle carried by the member and having a
concave runway for the clevis to traverse, a
covering saddle plate for the first-named
saddle, a roller in the clevis and contacting
with the wall of the runway, said covering 9
saddle plate having offset medial portions
to form clearance spaces for the clevis in its
movements, and filler blocks between the
saddle and covering saddle plate.
4. A draft appliance of the character de- 9
scribed comprising a swinging member hav-
ing trace-attaching devices at its ends, a
clevis loosely connected with the member, a
saddle carried by the member and having a
concave runway for the clevis to traverse, 1
a covering saddle plate for the first-named
saddle, a roller in the clevis and contacting
with the wall of the runway, said covering
saddle plate having offset medial portions to
form- clearance spaces for the clevis in its 1
movements, filler blocks between the saddle
and covering saddle plate, and means secur-
ing the said saddle, saddle plate and'member
together.
In testimony whereof I affix my signature 1
hereto.
