PROVISIONAL SPECIFICATION.
Improvements in Thill-couplings.
We, JAMES CARRALL WALKER, MARSHALL NAY BEDFORD, and FRED MEAD
YOUNGLOVE, all of Alpena, Alpena County, Mich., U.S.A., Inventors, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to provide a thill-coupling in which the parts are
prevented from rattling and said parts protected from dust and the weather.
The coupling consists of a clip which passes around the axle and bolster and has
a forwardly-projecting flat portion formed at its forward extremity with half
bearings to accommodate the spindle. Coiled springs extend between the spindle
and the clip to keep the spindle in place and prevent its rattling. A suitable cap
fits over these springs and has its forward edge formed with half bearings which
coincide with those aforementioned. The cap is kept in place by a screw bolt
passed through it and the horizontal projecting piece of the clip.

We, JAMES CARRALL WALKER, MARSHALL NAY BEDFORD, and FRED MEAD
YOUNGLOVE, of Alpena, Alpena County, Mich., U.S.A., Inventors, do bereby
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:
The invention relates to that class of thill couplings known as "antirattlers."
The object of the invention is to provide a coupling of this class in which the
anti-rattling devices are fully covered and protected from snow, ice, and dirt, and
in which the parts are few and simple in construction and readily separated for
repair, etc.
Reference being had to the drawings Figure 1 is a perspective of the coupling,
Fig. 2 is a similar view with the cap removed, and Fig. 3 shews certain details.
A represents the thill iron provided with a cylindrical cross head A¹ at its rear
end and secured to the thill B in the usual manner by the bolt C.
D represents the clip which fits over the bolster E and axle F and is secured in
place in the usual manner by the nuts d and the plate d', which rests against the
lower side of the axle. The front side of the clip D is formed or provided with a
forwardly projecting lug D' provided at its rearward end with a pair of upwardly
curved half bearings D, between which extends the shank of the thill iron A,
while the cross head A' thereof rests against the inner concave faces of the half
heerince D2

page_text: D' is a cover or cap which rests upon the upper side of the lug D¹ and is formed
at its forward end with two half boxes or bearings d', which register within the
bearings D and hold the thill iron in place.
G is a holt extending through aligned apertures in the lug D¹ and cover or
cap D³ and provided at its lower end with a nut g, the aperture in the lug D¹
being screw-threaded and the nut therefor acting as a lock nut. The lower face
of the cap or cover D³ is formed with two parallel grooves d', which extend from
the bearings d³ to the rear end of the cap, and in these grooves are placed spiral
or other springs K K, the rear ends of which bear against the front face of the
clip D, while the forward ends of the springs receive the stems of the concave
followers or anti-rattlers I, and the springs press these followers against the rear
side of the cross head A' with sufficient force to hold its forward side in contact
with the bearings D2 and thus take up wear and prevent rattling.
The springs and followers may be renewed when necessary by simply removing
the cap or cover D³, and the thill iron may be removed in the same way.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1.) In a thill coupling, the axle clip provided on its forward side with a lug
having a pair of half bearings to receive the head of the thill iron, a cover or cap,
resting on the upper face of the lug, and also having half bearings registering with
those of the lug; longitudinal grooves or channels being formed between the
adjacent faces of said lug and its cover or cap, springs within said grooves or
channels, to engage the head of the thill iron, and means of securing the cover or
cap to the lug, substantially as set forth.
(2.) In a thill coupling, the axle clip formed with a forwardly projecting lug
having a pair of upwardly extending half bearings at its front end to receive the
head of a thill iron, a cover or cap resting upon the upper face of the lug, provided
at its outer end with half bearings registering with those of the lug and formed in
its lower face with grooves extending from said half bearings to its rear end, spiral
or other springs mounted in said grooves with their rear ends resting against the
clip, followers at the forward ends of the springs and pressed thereby against the
rear end of the thill iron, and means for securing the cap or cover to the lug
substantially as set forth.
