Improvements in Thill Couplings.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co. Patent Agents,
45 Southampton Buildings, in the County of Middlesex do hereby declare the
nature of this invention to be as follows
--
This invention is an improvement in devices for preventing rattling in thill
couplings.
This invention has for its object to provide an adjustable spring adapted to
be interposed between the thill iron and the clip of the axle to prevent rattling
of the thill couplings, and it consists in a spring composed of two parts, one of
which has a bearing on the other whereby it may be rocked, the two parts being
connected by suitable means which permit the adjustment of the parts to the
distance between the clip and the socket of the thill iron, as will now be
described.
In carrying out the invention I provide an anti-rattling spring composed of two
parts or members which are interposed between the clip secured to the axle and
the socket on the thill iron, said members being composed of strips of steel or
other suitable metal. .One member bears against one side of the clip and may be
attached thereto by screws or not, as may be preferred. The other member is
formed with a concavity which fits the curvature of the inner side of the socket
and is adjustable towards or from the first mentioned member by an adjusting
device supported jointly by the two members. The said adjusting device may
a screw passing through orifices in the lower ends of the said members. Said
screw may be provided with a nut and with a head, said head bearing against one
member while the nut bears against the other member. The screw may be without
a nut and work in a threaded orifice in one member. One of the members is
curved inwardly to form a fulcrum or rest adapted to bear upon the other member
above the screw.
be
It will be seen that by adjusting the nut or turning the screw so as to force the
lower ends of the members toward each other, the concave end of one member will
be forced outwardly and caused to bear with an increased pressure on the socket.
while by an opposite adjustment of the screw the pressure of the said member
upon the socket may be decreased.
It will be seen that by this device I am enabled to adjust the pressure upon the
socket and accommodate the adjusting device to the width of the space existing
between the clip and the socket.
To prevent the accidental rotation of the screw or the nut, I provide the plate
or member with one or more outwardly bent ears which bear on the sides of the
nut and against the head of the bolt. One of the members may be provided with
a horizontal ear bearing on the upper ends of the clip ears and constituting a
desirable finish. Said ear also supports the device and prevents it from dropping
through the space between the clip and the socket.

Improvements in Thill Couplings.
I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings in the County of Middlesex, 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 is an improvement in devices for preventing rattling in thill
couplings.
The invention has for its object to provide an adjustable spring adapted to be
interposed between the thill-iron and the clip of the axle to prevent the rattling of
the thill couplings; and it consists in a spring composed of two parts, one of which
has a bearing on the other, whereby it may be rocked, the two parts being connected
by suitable means which permit the adjustment of the parts to the distance between
the clip and the socket of the thill-iron, as I will now proceed to describe.
of
In the accompanying drawings forming a part of this Specification,
Figure 1 represents a transverse section of a carriage-axle, showing one form
my improved device.
Fig. 2 represents a similar view showing a modification.
Fig. 3 represents a top view.
The same letters of reference indicate the same parts in all of the figures.
In the drawings,
a represents an axle, and b the clip, which is secured in the usual manner to
the axle and has the ears b', which receive the bolt c, that connects the socket d
of the thill-iron to said ears.
In carrying out my invention I provide an anti-rattling spring composed of
two parts or members e e¹, which are interposed between the clip b and the
socket d, said members being composed of strips of steel or other suitable metal.
The member e bears against one side of the clip and may be attached thereto by
screws or not, as may be preferred. The other member e¹ is formed with a
concavity, which fits the curvature of the inner side of the socket d, and is
adjustable toward or from the member e by an adjusting device supported
jointly by the two members e and e'. In Figures 1 and 2 I have shown the said
adjusting device as composed of a screw 9 passing through orifices in the lower
ends of the members e e'. In Fig. 1 said screw is shown as provided with a nut h
and with a head /', said head bearing against the member e, while the nut bears
against the member e¹. In Fig. 2 the screw has no nut and works in a threaded
orifice in the member e. The member e¹ is curved inwardly at e" to form a
fulcrum or rest adapted to bear upon the member e above the screw g. It will
be seen that by adjusting the nut h or turning the screw g, so as to force the lower
ends of the members e and e¹ toward each other, the concave end of the member e¹
will be forced outwardly and caused to bear with an increased pressure on the
socket d, while by an opposite adjustment of the screw the pressure of the member e
upon the socket may be decreased. It will be seen that by this device I am
enabled to adjust the pressure upon the socket d and accommodate the adjusting
device to the width of the space existing between the clip 6 and the socket d.
To prevent the accidental rotation of the screw g or the nut h, I provide the
plate or member e¹ with one or more outwardly-bent ears e³, which bear on the
sides of the nut, as in Fig. 1, and against the head of the bolt g, as in Fig. 2.
The member e is shown in Figures 1, 2 and 4 as provided with a horizontal ear e*,
bearing on the upper ends of the clip-ears b¹ and constituting a desirable finish.
Said ear also supports the device and prevents it from dropping through the
space between the clip and the socket d.

page_text: 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. The improved anti-rattling device for thill-couplings, composed of the spring
members ee, formed to be interposed between the clip and the socket of the
iron, one of said members having a concave portion formed to receive the socket
of the thill-iron and being fulcrumed on the other member, the adjusting bolt or
screw connecting the outer ends of said members, and the ear et formed on one
of the members and arranged to bear on the ears of the clip, as set forth.
2. The improved anti-rattling device for thill-couplings, composed of the spring
members e e¹, formed to be interposed between the clip and the socket of the iron,
the adjusting bolt or screw connecting the outer ends of said members, and the ear
or ears e, formed on one of said members to prevent the loosening of the bolt or
screw, as set forth.
