Improvements in the Means for Attaching Valve Caps to Valves.
I, JAMES DALE Junr. of 73, Pimlico Road, London, Gentleman, do hereby
declare the nature of this invention and in what name the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in the means for attaching the valve cap
to the body of the valve so as to prevent the said cap being lost when it is removed,
these improvements being more particularly applicable to the valves used i
connection with the pneuniatic tyres of velocipedes and the like The object of
this invention is to provide a bandier method of connection than the chain now
generally used for this purpose, while by my improvements the cap can be more
easily removed and replaced than has hitherto been possible.
In order that my invention may be fully understood, I will now proceed to
describe same with reference to the accompanying diawings in which
Fig is a side elevation of a valve fitted with my improved attachment, with
the cap in position for screwing down and Fig. 2 is a similar view with the valve
cap sciewed down.
Figs. 3, 4 and 5 are three side elevations of a slightly modified form of attach-
ment showing the cap a position for sciewing down, screwed down and thrown
open for inflating purposes, respectively
Fig 6 shows a different form of attachment and
Figs 7 and 8 show two views of a slightly different attachment with the cap open
and screwed down, respectively,
Figs 9 and 10, 11 and 12, 13 and 14 being similar views of further modified
forms with the caps in the open and closed positions
Fig 1 shown at night angles to Fig. 9.
The form of attachment shown in Figs 1 and 2 consists of a spring arm a
secuned to the cape and body of valved by the bands and respectively, the
Enid cap being free to revolve within the band or collai b. For the purpose of
inflation, the cap is turned into the position shown in dotted lines (Fig. 1) while
when screwed down (Fig. 2) the aim a assumes a curved shape as shown.
In the modification shown in Figs 3 4 and 5 the sping aim a is replaced by one
gidly constructed, which is permanently secured to the body of the valve by
the band, the other end being connected to the cap c by a cuculai band b, in such
a mauner as to allow the cap to shde up and down through same, a coiled spung s
being aanged between the top of the cap and the said band b. Fig. 4 shows the
cap screwed down when the coiled springs is compressed as shown, while upon
unscrewing the cap the spring assumes the position shown in Fig. 3 when the aim a
can be turned back as shown in Fig 5 for inflating purposes.
Fig. 6 shows another form fitted with a spring cap as in Figs. 3, 4 and 5. In
this case two arms a, a' are employed secured to pins p, p, projecting from the band
or clip , while the band connects the aims u, a to the cap The pins P, Pact
as a hinge so that the cap can be turned back for inflating puposes, while in
addition may provide any suitable spring such as aanged so as to automatically
throw back the cape when it is unscrewed from the valve, and which can obviously
be applied to any of the forms shown in the drawings foi automatically thowing
back the cap when it is released from the valve.

page_text: The modified form shown in Figs. 7 and 8 is practically the same as that shown
in Figs. 1 and 2 with the exception that two sping aims a,, are employed both
of which assume a curved position when the cap is screwed down as shown.
In the form shown in Figs 9 and 10 the arm a is furnished with a slot s² through
which the pin p passes to secure it to the body of the valve; when the cap is
screwed down the pin p bears against the top of the slot while when the cap is
unscrewed the bottom of the slot is brought up into contact with the pin p
Figs 11 and 12 show a slightly modified form, of the attachment shown in
Figs. 9 and 10, in which case the slot s² is made in the top end of the aim a instead
of at the bottom end of same.
The modified form shown in Figs 13 and 14, consists of two arms a, a connected
to the cap c by band b, while a stop el may be ananged to prevent the band & from
moving in an upward direction. The ends of the arms a, a¹ are connected by the
band to the body of the valve, the said band being capable of sliding up and
down, while the sping s is a ranged between the bottom of the body and the band 61,
When the cap is screwed down the springs is compressed as shown in Fig. 14,
while as the cap c is unscrewed the said springs gradually raises the arms until
the cap is removed from the top of the valve, when it can be tuned over to one
side foi inflating purposes, the arms a, a', turning on the pius p.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claun is.-
1. The improved means of securing the cap to the body of the valve consisting of
the sping arm a in combination with the bands b, b, substantially as herem
described and shown in Figs 1 and 2, of the accompanying drawings and for the
purposes specified.
tho
2 The inodified form of attachment consisting of the arm a in combination with
spring s
and bands b, b substantially as herein described and shown in Figs 3,
4 and 5.
3. The further modifications in the form of attachment substantially as heroin
described and shown in Figs. 6 to 14 of the accompanying drawings.
Dated this 16th day of October 1895.
