Improvements in Tire Tighteners.
I HENRY FRANCIS TALBOT of 7 Cherry Street Birmingham in the County
of Warwick 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
ascertained in and by the following statement :-
Reference being made to the accompanying drawings in which,
Fig. 1 is a side elevation embodying the invention.
Fig. 2 a plan of same.
Fig. 3 a vertical section of followers shewing leather grip face.
Fig. 4 view of screw plate for horizontal motion.
Fig. pian or leather washer.
.
The invention relates to the combination of duplex tire tighteners for the repair
of wagon wheels and the tire setting instead of the single jack with less danger in
raising felloes, saving labour and with more equal balance generally.
Secondly it relates to the combination of duplex tire tighteners with leather
facings in follower and frame, to obtain a steadier grip on spoke, and protection to
paint and wood of same.
In drawings Fig. 2. A is a bed or frame of a machine for tire tightening manu-
factured of cast iron in a substantial manner, designed in forked shape as shewn, to
admit of follower B traversing the frame and being propelled into position when
the machine is placed around the spoke G by horizontal screw C manufactured of
cast steel, and passing through the screw plate E grips the spoke G of wheel H.
In order to obtain a true bearing and keep the follower B in true position the
additional screw jack D is applied in conjunction with the screw jack J, so that
when the wrench L is applied to the screw jacks D and J " compound or duplex
motion" is obtained and the felloe of the wheel H raised as shewn in Fig. 1. leaving
the necessary space to place the leather washer I and for repairing.
The term "compound or duplex motion is used to indicate that the action of the
screw jacks D. and J. may be said to be "compound," in as much as, they are two
conspiring powers, acting in somewhat different, but not opposite directions, or that
a "double" motion is used for the raising of the felloe of the wheel H by the
application of the two screw jacks D and J working on the one frame A.
The machine is applied in the following manner: The forked shaped frame A
is placed round the spoke G, the follower B slid on and caused to tightly grip the
spoke by turning the horizontal screw C which passes through the plate E which
has also been placed on the forks of the frame. The screw jacks D and J are then
turned, by applying the wrench L. to each, so as to equally raise the felloe of the
wheel H on both sides of the spoke G. The leather washer I is then inserted.
The follower B is flanged on sides and bottom and faced with leather F. in arc
as shewn in Figs. 2 and 3. Also leather is in face of arc K of frame A.
The duplex vertical motion gives a more certain balance, so necessary in the
repair of wheels, the leather in arcs reduces strain on spoke, protects paint, lessens
labour and cost generally for the repairs of wagon or other wheels.

page_text: Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. The combination of extra vertical screw jack D with J, or duplex vertical
motion for tire tighteners as set forth.
2. The combination of duplex vertical motion tire tighteners with leather
facing K and F for followers and frame substantially as and for the purposes set
forth.
