Improvements in or relating to Apparatus for Repairing Pneumatic
Tyres.
A communication from WARREN HERBERT BEEDE and ANNA LUCRETIA WEBBER,
both residents of Lynn, County of Essex, in the State of Massachusetts,
United States of America.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered 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 ascer-
tained in and by the following statement:
Of the accompanying drawings Fig. 1 is an elevation of one side and Fig. 2 an
elevation of a section of the machine embodying this invention. Fig. 3 and Fig. 4
represent details referred to and further described hereinafter.
The machine comprises a body part, 2, arranged for supporting on the top thereof
the clamping member, 4. Said body part has within it an oven or chamber, 3,
wherein is located the heating medium, 5, the one represented being an ordinary
"Bunsen Burner" for the common illuminating gas, but obviously other heating
apparatus may be employed if desired. At or near the top of said ovens are open-
ings, 6, 6, extending through the walls thereof outwardly on opposite sides of the
body part and integrant with or otherwise secured firmly to the body part, and
projecting laterally therefrom are shelves, 7, 12, one above each of the openings, 6,
said shelves being intended for holding clamping members as further to be described
hereinafter.
The arm, 8, has pivoted connection with the body part, 2, whereby to permit
swinging movement from the horizontal position indicated by dotted lines (Fig. 1)
to a vertical position with its free or top end above the shelf, 7. In the top or
free end of arm, 8, is a wheeled-shaft, 9, having screw-threaded connection in the
and
arm, 8, whereby the shaft, when suitably turned, may be moved vertically up
down for pressing downwardly upon the work-repairing clamp members placed
therebelow upon the shelf, 7.
Supported in the body part, 2, is an upwardly extending part, 13, whereon is
supported the bracket arm, 14, having in its outer end a wheeled-shaft, 15, with
screw-threaded connections therewith for causing vertical reciprocations of the
shaft when turned; all this for pressing together the work-repairing clamp members
placed therebelow upon the shaft, 12.
On the post, 13, is a bracket, 16, adapted for sliding movement on the post in
order for quick and easy arrangement to different altitudes, and it is securable to
the post at any desirable altitude by the manually operated set-screw, 17. Said
bracket, 16, has its outer end in line above the body part, 2, and supports a wheeled-
shaft, 18, to the bottom end whereof is attached the clamping member, 20. Said
shaft, 18, has screw-threaded engagement in the arm, 16, whereby the shaft, when

page_text: suitably turned, is reciprocated vertically for lifting and lowering the clamping
member, 20, and consequently closing it down upon a tire placed therebelow in
clamping member, 4. The clamping members, 4 and 20, are designed for use in
repairing a tire while it is in an inflated condition. To this end the members are
provided with tire receiving channels, 22, running longitudinally thereof, said
channels being substantially semi-circular in cross section and approximately in
depth the half diameter of an ordinary wheel tire. The members are intended
for working upon the outer face or periphery of the tire. and also upon the inner
face thereof and to this end the channel, 22, in one member, 4, is made longitu-
dinally concaved, while the channel, 22, in the other member, 20, is made longitu-
dinally convexed (see Fig. 2). The vulcanizing member, it will be understood,
is always placed upon the top of the body part, 2, in order to become, heated
sufficiently for melting the repairing materials. And to this end the members
are made interchangeable, each one provided with a tongue piece to enter the
socket in shoe, 24, on bottom end of shaft, 18, whereto it is secured, temporarily
by the pin, 25.
Obviously when the repair is to be made upon the peripheral face of the tire,
the clamp member, 4, is placed below and the tire body will extend vertically
above the post, 13, where it is engagable with the steady-rod, 26, for support during
the vulcanizing operation. But when the repair is to be made on the inner face
of the tire, the clamp member, 20, is placed below and the tire body will, then
hang downwardly, requiring in this case no special means for support.
".
Besides the work commonly met with that may be done in the clamp mem-
bers, 4, 20, with the tire inflated it at times becomes desirable to conduct the work
of repair with the tire in a collapsed and flattened condition. In such cases clamp-
ing members with flat or approximately flat faces are employed, according to the
nature of the work to be performed. In Fig. 3 of the drawings is represented in
section the work of repairing a tire wherein is employed a flat-faced clamp-mem-
ber, 28, and a clamp-member, 29, having its face concaved or chambered out to
form a cavity or depression 30, see Fig. 4. In use this chamber is located above
the puncture or place in the tire intended to be repaired, which place having been
filled with the repair material, the clamping members are pressed tightly together,
firmly compressing the work therebetween. The heat is next applied and as the
repair material becomes melted it runs together in the cavity, 30, and is shaped
up by the walls of said cavity, being heaped and made thickest in the center or
punctured point.

The clamp members, 4, 20, may be removed entirely and give place for other
clamp members to be used in place thereof when desired.
In this connection it will be understood one purpose of the shelves, 7, 12, is to
hold the different clamp members which may happen to be temporarily out of use
and which are thereby kept hot and always in readiness for use without the delay
required for heating from the cooled state in every instance of primary use as
heretofore. In Fig. 1 the shelves, 7, 12, are represented as supporting and con-
sequently keeping hot the clamping members which are commonly employed in
doing different kinds of repair work.
But in the machine represented the shelves, 7, 12, are further employed at times
for supporting a bottom or heated member in actual working use. In such case
the work for repair is placed upon the member thus supported and above it is
placed a top member to be actuated downwardly by the screw-shaft 9, or 15, as
the case may be, whereupon the work of melting and repairing the tire clamped
therebetween goes on as in the case above described.
From the foregoing it will be obvious that the machine represented is adapted
for work to be carried on therewith at three different points or places all at one
time, and the work at each place may be of a separate or special character accord-
ing to the clamping members employed. This very much increases the capacity of
the machine for turning off work, besides the economical consideration that one
heat is made to serve for all the operations.
