JOSEPH ROBINSON BENSON, OF SONORA, TEXAS.
THILL-COUPLING.
SPECIFICATION forming part of Letters Patent No. 489,407, dated January 3,1893.
Appliationfiled May 18, 1892. Serial No. 433,407. (No model.)To all whom it may concern:
Be it known that I, JOSEPH ROBINSON BEN-
SON, of Sonora, in the county of Sutton and
State of Texas, have invented certain new and
5 useful Improvements in Thill-Couplings; and
I do hereby declare the following to be a full,
clear, and exact description of the invention,
such as will enable others skilled in the art
to which it pertains to make and use it, ref-
to erence being had to the accompanying draw-
ings, which form part of this specification.
My invention relates to an improvement in
thill couplings: and it consists in the novel
features of construction which will be fully
15 described hereinafter and more particularly
referred to in the claim.
The object of my invention is to construct
a coupling which is readily detachable from
the axle clip, but which when in place is held
20 in a most secure manner.
Referring to the accompanying drawings,-
Figure 1 is a perspective view of my improved
thill coupling showing its position on the clip
of a vehicle. Fig. 2, is a detached view of
25 the same.
A, represents the arm of the coupling which
is secured to the rear end of the shaft or thill,
and pivotally secured to the outer end thereof
is the jaw B, which is adapted to be turned
30o down on the arm A, as shown. Formed in
the adjacent faces of the arm and jaw just
forward from the pivotal point is the opening
C, through which the clip bolt passes. Upon
the under side of the arm A, is the lug D, and
35 secured therein is the link E, which extends
up around the arm A, and when the jaw B, is
turned down the link may be pushed over itsouter end and thus hold the two securely to-
gether. In order to prevent the link from
slipping off the end of the jaw and thus open- 40
ing the coupling prematurely a spring E, is
provided which fits within a longitudinal re-
cess in the upper face of the jaw B. On the
outer end of this spring is formed the head F,
and as the spring must be depressed before 45
the link will swing over it it is apparent that
when it is passed over the said head the lat-
ter raising it to its normal position will hold
the link securely behind it. A most secure
coupling is thus formed which may be re- 50
moved by simply pressing downward on the
headed end of the spring, allowing the link to
swing forward releasing the jaw, and the lat-
ter being turned on its pivot the thills may
be easily removed from the clips on the axle. 55
Having thus described my invention, I
claim
In a thill coupling the combination of a
thill arm A, perforated lug D on the under
side thereof, link E confined in said perfo- 60o
rated lug and surrounding the said arm, jaw
B pivotally secured to the rear end of the arm
and adapted to turn down thereon and spring
E' having head F confined in a depression in
the upper side of the jaw for the purpose of 65
securing the link E over the free end of the
jaw, substantially as shown and described.
In testimony whereof I affix my signature in
presence of two witnesses.
JOSEPH ROBINSON BENSON.
