Improvements in Devices for Setting or Fixing Rubber Tires to
Vehicle Wheels.
I, HERBERT JOHN HADDAN, of the Firm of Herbert Haddan & Co., of 1
Buckingham Street, Strand, W.C., Consulting Engineer, do hereby declare t
nature of this invention, a communication to me from abroad by Frederic
Stewart, of 30; Broad Street, in the City of New York, United States
5 America, Lawyer, and in what manner the same is to be performed, to b
particularly described and ascertained in and by the following statement:-

The invention has relation to improvements in devices for setting the solic
rubber tires of vehicles in which the tire rests in a channeled metallic tire, and
is reinforced by longitudinal wires embedded in the rubber.
The objects of this invention. are to securely set said tires in place by com-
pressing the rubber longitudinally on the embedded wires and permit them to
project sufficiently to be gripped by clamps; by drawing the projecting wires
together when the rubber shall be placed in the channeled tire; to place them
in tension; and by sliding the ends of the compressed rubber together over the
united ends of the wires; and finally fastening the ends of the rubber to complete
the tire.
To the aforesaid objects the invention consists in the peculiar and novel con-
struction arrangement and combination of parts and their mutual co-operation
hereinafter described and then specifically pointed out in the claims, reference
being had to the accompanying drawings forming a part of this specification.
In the accompanying drawings in which similar reference numerals indicate
like parts in the different figures.

mechanism.

long the wires to bring the ends together, and

e rubber on the wires.
Referring to these drawings, 1 is a table having at one side a fixed raised strip
ledge 2 graduated for convenience of measuring the rubber in such manner
will best subserve the purpose. Opposite the fixed ledge 2 is a free board 3,
erced with parallel diagonal slots 4, through which pass bolts 5 fastened in
table 1, and provided with thumb nuts 6 on which it may be moved toward
from the ledge 2 and retained parallel therewith at any distance, to accommo-
e the device to varying widths of tire. The ledge of the board 3 adjacent
the ledge 2 is cut away at the point 7 to permit of a movement of a sliding
tch hereinafter described. At the opposite end of the

and 2) and opposite the fixed ledge 2 is a short similar ledge 8,
and through both ledges at a right angle, a saw channel 9 in which to insert
a tool to cut the rubber at the desired length, and at an accurate angle.
Fitted and arranged to slide in the channel thus formed on the table 1 are
two clamps 10, each consisting of a central post 11, having a notch 12 at its
upper extended end for a purpose to be stated, and two side jaws 13 adapted to
be compressed against the bottom of the post 11 by a bolt 14 and held in position
by a guide pin 15. Arranged to slide in the same channel is a clamp 16, pro-
vided with a bolt by which it may be tightened, and adapted to grasp the ends
of the tire wires. This clamp 16 is connected by means of a hook 17 with a
sprocket chain 18, that runs on a sprocket 19 on a shaft 20 journaled in the
board 1 and provided with a crank handle 21 arranged to be retained by a pawl 23.
Across the table 1 in recesses cut therein on the upper and lower surfaces
are two plates 24 securely fastened each perforated with a hole, in alignment
with each other to receive a pin 34, to constitute an abutment against which
the clamps nearest the ratchet wheel rest. For convenience in adjusting this
abutment to varying widths of tire a number of holes may be made across these
plates 24, but it has not been deemed necessary to show more than one. As thus
far described the operation of the apparatus is as follows: The tire is placed in
the channel on the table 1, and its proper length having been ascertained by
means of the graduated edge, is cut off with a tool in the mitre grooves 9;
wires are then inserted in openings made for that purpose and their projecting
ends fastened in the clamps 10 farthest from the sprocket wheel and passed
loosely between the jaws of the opposite clamp which rests against the abutment
pin 34 and fastened in the clamp 16. The shaft 20 is then turned drawing the
wires in one direction and compressing the tire endwise until the desired degree
of compression is secured when the clamp against the abutment pin is tightened
and the chain released and the clamp 16 freed. The tire with the clamps 10
holding the ends of the wires is then removed and passed about the wheel 25 in
the channel of the iron tire and carried to the apparatus shown in Figure 4.
This apparatus consists of two parallel guide rods 26 supported between brackets
extending from a plate 27 adapted to be fastened to a firm post or other support
and on which is a slide 28 arranged to be held at any height by a set screw
operated by a hand wheel 29 and having a projecting shaft 30. On this shaft
is pivotally supported a yoke 31 arranged to be held by a set screw 32. Near
the corners of this yoke are oppositely disposed openings in which freely move
bolts 33, having their inner ends offset and bent in a right angled hook as shown
in Figure 6.
The opposite ends of these bolts are screw threaded and fitted to hand-wheel
nuts 34. In the ends of the yoke 31 are screw threaded openings in which are
oppositely disposed screws 35 having on their inner ends free pointed heads 36.
The wheel with the tire and clamps as herein before stated being brought to this
apparatus and properly supported on a stub axle or other convenient manner,
the notched ends of the centre posts 11 of the clamps 10 are inserted in the
hook ends of the bolts 33. The screws 35 are then turned inward against the
lower part of the clanips 10, as shown in Figure 4, and turned up until the
wires are in tension, and their ends pass each other; during this process the
set screw operated by the hand-wheel 29, and the set screw 32, are released to
permit the yoke to rise or fall freely and to rock in either direction to accommodate
itself to the position of the wires, and the bolts 33 serve to direct the motion
of the wires in a tangent to the circumference of the wheel and to insure their
uniting accurately, this being accomplished by turning the hand nuts to raise
the wires and releasing them to lower them. The ends of the wires are then
brazed together and when cool the clamps are removed.
The tire is now compressed endwise on the wires, and the wires in tension and
fastened to bring forward the ends of the rubber to meet and form a union,
short wires 37 (see Figs. 10 and 11) having been previously passed under the

page_text: in holes in a bar 38 by means of set screws 39. A post 40 is then placed endwis
eir ends projecting; the ends of these wires are then fastene
on the floor adjacent to the wheel, in the upper end of which are two plates 4.
which are then made to extend in front of the post and between which is journaled
5 a roller 42, and between which at their highest part is a screw rod 43, althougi
for convenience the post 40 is shown for the purpose of forming a fulcrum for
the lever 44, any other support that will subserve the purpose in the same relative
position may obviously be substituted.
A short lever 44, having at its end on opposite sides similar plates 45 is then
10 used, the upper ends of these plates having similar hooks 46 to engage one of
the bars 38 and their opposite edges are provided with notches 47 to rest on the
rod 43; the handle of the lever is then pressed down, drawing the tire away
from the channel of the metallic tire, and the wheel 25 slowly turned toward
the device, the result being to permit the rubber to expand as it is freed from
5 the channel of the iron tire, and consequently to elongate towards its cut end,
the wires 37 serving to raise the rubber from the channel of the iron tire and
the roller 42 operating to press it along the wires. This operation is continued
on each end of the wire until its ends meet, when they are cemented together
and the wires 37 withdrawn, leaving a complete rubber tire on the wheel. In
process cement may or may not be used to cause the rubber and metal tires to
adhere, and if cement is used it may be placed in the channel of the iron tire
before the rubber is inserted, or it may be applied with a narrow spouted can
under the rubber as it
these operations also the rubber is compressed equally about the wheel and
raised by the wires 37, as the wheel is revolved. By
equally stretched along the wires as hereinbefore stated and tension is equally
distributed around the wheel.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:
