Improvements in Apparatus for inserting
Strips, or Treads into Grooved or Recessed Metal Tyres.
I JOSEPH SHAW of Wilson Street Stockport Road, Manchester, in the County of
Lancaster, Coach Builder, do hereby declare the nature of this Invention to be as
follows:-
My said Invention relates to apparatus for inserting rubber rings, bands, strips or
treads into grooved or recessed metal tyres, such for example as form the subject
matter of Letters Patent No. 11,204 granted to me on the 3rd day of September 1886.
The said tyres have undercut or overhanging sides and the rubber rings or treads being
correspondingly formed are difficult to force into the tyres. According to my inven-
tion I use an inserting tool consisting of a bracket which can be fitted or adjusted to
clip or lay hold of the tyre or wheel felloe. Upon this bracket or clip I pivot a lever
formed at one end with a handle and at the other with a compressing and inserting
toe which bears upon the rubber. When the lever is operated this toe compresses the
rubber and forces the base into the grooved tyre by which it is securely held. The
clip bracket is or may be formed with a handle which is grasped by the operator when
the pivotted lever is worked so as to counteract the canting strain which would other-
wise be imparted to the bracket and consequently to the tyre and felloe. The clip
lever is moved round the felloc or tyre or the wheel itself is moved round as the work
proceeds so as to operate continuously upon the entire circumference of the ring or
tread. The pivot of the inserting lever is rendered readily adjustable upon the bracket
so as to provide for different sizes of rubber rings and tyres. The clip bracket may
either be made solid so as to suit a specific size of tyre or felloe or it may be made
adjustable by a screw or other means so as to suit varying sizes. To give the clip
bracket increased powers of resistance to the canting pressure brought to bear upon it
by the inserting lever, I might form that side of the lever which is opposite to the
handle with a broad foot or tail which would bear upon the felloe and tyre.

JOSEPH SHAW of Wilson Street, Stockport Road, Manchester, in the County of
Lancaster, Coach Builder, 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 and accompanying drawings :—
My said Invention relates to apparatus for inserting rubber rings, bands, strips or
treads into grooved or recessed metal tyres, such for example as form the subject
mmiter of Lotters Patent No. 11,204 granted to me on the 3rd day of September 1886.
The said tyres have underent or overhanging sides and the rubber rings or treads
being correspondingly formed are difficult to force into the tyres. According to my
invention I use an inserting tool consisting of a bracket which can be fitted or adjusted
to elip or lay hold of the tyre or wheel felloe. Upon this bracket or clip 1 pivot a
lever formed at one end with a handle and at the other with a compressing and
inserting toe which bears upon the rubber. When the lever is operated this toe
compressos the rubber and forces the base into the grooved tyre by which it is securely
held. The clip bracket is or may be formed with a handle which is grasped by the
operator when the pivotted lever is worked so as to counteract the canting strain
which would otherwise be imparted to the bracket and consequently to the tyre and
felloe. The clip lever is moved round the felloe or tyro or the wheel itself is moved
round as the work proceeds so as to operate continuously upon the entire circumference
of the ring or tread. The pivot of the inserting lever is rendered readily adjustable
upon the bracket so as to provide for different sizes of rubber rings and tyres. The
clip bracket may either be unde solid so as to suit a specific size of tyre or felloo or it
may be made adjustable by a screw or other means so as to suit varying sizes. To give
the clip bracket increased powers of resistance to the canting pressure brought to
bear upon it by the inserting lever, I might form that side of the lever which
is opposite to the handlo with a broad foot or tail which would boar upon the felloe
and tyre.
To render my invention more clear I will now proceed to describe the same with
reference to the necompanying shoet of drawings in which Fig. 1 is an end olevation
and Fig. 2a side view of the inserting tool constituting my invention. The tool
consists of two main parts, the bracket a and the inserting hook or lever b. In the
drawing the tool is shown as it appears when used to force or insert a rubber ring or
tread e into the channel tyre d which is shown fixed to the rim or falloo of a wlicel.
The bracket a is formed to bridge over the folloe and tyre and on one side rests by the
fixed foot against one side of the channel tyre d and on the other by the adjustablo
foot or tail gagainst the other side of the channel tyre. The foot g is adjusted by
means of the screw operated by a hand wheel h² so that the foot bear firmly on cuch
side of the tyre and rim and the bracket cannot be canted or displaced by the operation

page_text: of the inserting hook lever b. I form the bracket a with a handle or extension a'
which is grasped by the operator when the inserting hook lever b is used so as to shift
the bracket and to assist in counteracting the canting strain upon the bracket and
consequently upon the tyre and felloc. The inserting hook lover b is pivotted to the
bracket a by an adjustable pivot i so as to provide for different sizes of rubber rings
and tyres. The inserting lever is formed with a hooked termination as shown forming
an inserting toe which when the pivotted lover is operated presses downward upon the
rubber ring and forces the base into the channel tyre d by the curved sides of which
it is securely held as shown in Fig. 3 which is a section of the channel tyre with the
rubber ring properly inserted. As the insertion proceeds the tool is moved round the
felloe or tyre or the wheel itself is turned as the work proceeds so as to operate con-
tinuously upon the ontire circumference of the ring or tread. In Fig. 1 the portion
marked A of the rubber is supposed to have been inserted, while the portion marked B
has yet to be acted upon by the tool. Instead of having one foot adjustable by a screw
as shown both feet might be made adjustable or the foot or feot might be made adjust-
able by any other suitable means such as a ruck or a series of perforations and a pin
or bolt or the feat might be made fixed to suit a specific size or type of tyre. The
tool might be used for inserting rubber rings or tyres of sections other than that
shown in the drawings.
Having now particularly described and ascertained the nature of
my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
(1) The tool or apparatus for inserting rubber rings, strips, treads, or bands into
grooved or recessed metal tyres and constructed and operated substantially as herein-
before described and shown.
(2) In a tool or apparatus for the indicated purpose a bracket such as the bracket a
capable of being applied to the sides of the rim or tyre in combination with a pivotted
lever such as so formed as to be capable of forcing or inserting the rubber ring, tread
or strip into a metal tyre of undercut section, both bracket and lever being constructed,
applied and operated in the manner or substantially in the manner herein before
described and shown.
