ALEX L. CHEEK, OF ROXTON, TEXAS.
VALVE.1.362,526.
Specification of Letters Patent. Patented Dec. 14, 1920.
Application fild November 18, 1919. Serial No. 338,809.To all whom it may concern:
Be it known that I, ALEX L. CHEEK, a
citizen of the United States, residing at
Roxton, in the county of Lamar and State
5 of Texas, have invented new and useful Im-
provements in Valves, of which the follow-
.ing is a specification.
This invention relates 'to valves and has
particular application to that class of valves
10 used in conjunction. with pneumatic inner
tubes, the invention residing in the con-
struction, combination and arrangement of
parts which prevent leakage of the valve.
The nature and advantages of the inven-
15 tion will be better understood when the fol-
lowing detail- description is taken in con-
nection with the accompanying drawings,
wheirein like numerals of reference indicate
similar parts iii the several views, and in
20 which:-
Figure 1 is a view showing the component
parts of the invention separated:
Fig. 2 is a vertical sectional view through,
the valve.
25 Fig. 3 is a perspective view of the cone
shaped member or packing.'
The valve constructed in accordance with
-my invention embodies a tubular relatively
long section 10, and a relatively short sec-
30 tion 11. The section 10 is reduced as at 12
to provide a neck for association with the
inner tube in the usual manner, the inner
tube not being shown. The section 10 is
provided with a longitudinal bore 13, which
35 opens into a counter bore 14 at one end of
the section. The section 11 is externally
threaded adjacent its opposite ends and is
adapted to be threaded into the counter-bore
14. The section 11 is provided with an en-
40 larged angular -intermediate portion 15 to
accommodate a tool for associating the sec-
tions or disassembling the parts as the oc-
casion may require. The section 11 is also
provided with a longitudinal bore opening
45 at both ends, the bore indicated at 16 being
substantially cone-shaped at one end as at
17. The portion 17 of the bore is adapted
.to receive a substantially cone shaped pack-
ing member which is indicated in Fig. 3,
50 which member is preferably constructed
from rubber, or any other suitable material
may be utilized in its projection; The pack-
ing 18 is within the cone-shaped portion of
the bore 17,-the packing having a flange 19
55 around its smaller extremity which is fitted
within an internal groove 20 provided inthe section 11. The opposite end of the
member 18 is ,also provided with a flange
21 which embraces, or surrounds the ad-
jacent end of the section 11. When the 60
section 11 is threaded into the counter-bore
14, the flange 21 of the packing member is
interposed adjacent the section 11 and the
shoulder 22 formed in the.section 10. By
reason of this : construction, the packing 65
member is effectively secured between the
respective sections of the valve, and is ar-
ranged to prevent leakage of the latter, the
flange 19 being fitted within the groove 20
of the section 11 preventing the packing 70
from being closed or collapsed when air is
introduced into the valve. The section 10
is provided with a shoulder 23 adjacent the
neck 12, and upon this shoulder is seated
one end of a coil-spring 24, the spring being 75
disposed within the bore and having its op-
posite end bearing against- a ball valve 25,
normally holding the latter seated -within
the packing member 18. Manifestly, when
air is introduced into the valve through the 80
section 11, the valve is moved away from the
seat against the tension of the spring, and
when the tube has been properly inflated the
spring returns the valve 25 to normal posi-
tion. The construction is such that the com- 85
ponent parts can be 'readily separated for
the purpose. of cleaning the same oir for the
purpose of repairs when the occasion re-
quires.
While I have shown and described what 90
I consider the preferred embodiment of the
invention, I desire to have it understood that
I do not limit myself in this connection, and
that such changes may be resorted to when
desired as fall within the scope of what is 95
claimed.
Having thus described my invention what
I claim as new is
A valve comprising detachably connected
sections-having alined bores, the bore in one 1oo
section being substantially cone shaped for
' a portion of its length, said section having
an annular groove, a packing sleeve fitted in
said cone shaped .portion, a flange around
each end of the sleeve, one flange being fitted 105
in said groove, the other flange embracing
the adjacent end of said section and adapted
to be -impinged between said sections when
the' latter' are associated,' and. a valve ar-
ranged between said sections and operating 110
in said sleeve.
