An Improved Device for Attaching the Breeching to the Shafts of
Road Vehicles.
A communication by SAMUEL F. ROBBINS, of Langhorne, in the County of
Bucks and State of Pennsylvania, United States of America, Carpenter.
1, GEORGE CECIL DYMOND, M.I. Mech. E., of The Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester,
both in the County of Lancaster, and 323, High Holborn, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to a device adapted to be applied to the thills or shafts of
carriages or like vehicles to afford a simple and efficient means of attachment for
the hold-back or quiler straps of the usual harness breeching; and, as generally
stated, it consists in the combination with a suitable base provided with a projecting
hook portion, of a locking member mounted in said base in such manner that the
free end of the locking member bears with spring pressure against the under edge
of the hook, thereby preventing the accidental disengagement from the latter of an
eye or loop on the end of the quiler strap. It also consists in various details of
construction that will be hereinafter pointed out.
In the drawings :-
Figure 1 is a vertical longitudinal section of the device.
Figure 2 is a transverse section, as on the line 1-2 of Figure 1.
Referring to these drawings, wherein the preferred form of the invention is
illustrated, A represents a block or casting comprising a base with a vertical rib, a¹,
in which is formed an inwardly curving recess a² that converts the forward part of
the rib into a hook A'. This rib, as also the base plate, is partially cored out
vertically so as to form therein a narrow chamber a³ with a shoulder a beyond the
inner edge of the hook, a shoulder a³ in the lower opposite edge of the chamber
and a cross bar a just forward of the latter shoulder.
B
represents a spring of flat steel or other suitable material, which is bent as
shown in the drawing, that is to say, it has an up-curving portion the free end of
which is engaged, against its own spring pressure, with the rearward shoulder a³
and bar a and a forwardly-extending portion that normally extends beneath the
hook and under the shoulder at. This forward portion of the spring has a slight
upward bend or rise that takes forcibly against the lower forward end of the
hook. The latter is formed slightly rounded and drooped, so as readily to receive
the ring e on the end of the quiler strap.
The base plate is provided with a screw or bolt holes h whereby it may be
fastened to the usual thill or shaft D of the vehicle.
By the described construction it will be obvious that the ring c may be engaged
with the book very quickly, and that when it is so engaged the ring will be
effectually held in place by the spring guard, as it may be termed, the shoulder or
rise 62 in the latter in conjunction with the peculiarly-formed hook, preventing
end wise movement of the ring, and the sides of said hook preventing lateral
displacement of the ring. The side walls of the chamber a3 support the edges of
the spring and maintain the same in place.
It will be seen that in this construction no nice fitting or adjustment of parts is
required, the device consisting simply of two members that are held together, by
frictional action, without the intervention of rivets or pins.

page_text: It may be remarked that the free end of the spring is so bent in respect to the
under edge of the hook, that when the quiler-strap ring is engaged with the latter,
the spring bears forcibly against the ring, as seen more clearly in Figure 1, thereby
clamping the hook snugly in place and preventing rattling thereof.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. A hold back consisting of a frame with an overhanging hook at one end
thereof, a cross-bar on the frame between the opposite end thereof and the end of
the overhanging book and a spring having suitable securing bearings in the opposite
ends of the frame, bent over the cross-bar and beneath the overhanging hook,
substantially as described.
2. The combination of the ribbed base having formed thereon a hook and having
its interior hollowed out to form the narrow chamber, with its shoulders a' a³ and
cross-piece a and the spring fitted to said chamber in such manner that the lower
end of the spring is engaged with the piece a and shoulder a and its free end
projecting below the shoulder a substantially as described.
3. The general combined arrangement or construction of parts substantially as
herein set forth.
