RICHARD ANTON GOETH, ROBERT B. RODGERS, AND JOHN ALBERT DITTMAR, OF SAN
ANTONIO, TEXAS.
AUTOMOBILE-PUMP.Specification of Letters Patent. Patented Mar. 4,1913.
Application filed April 26, 1912. Serial No. 693,410.To all whom it may concern:
Be it known that we, RICHARD ANTON
GOETH, ROBERT B. RODGERS, and JOHN AL-
BERT DITTIAR, citizens of the United States,
5 and residents of San Antonio, in the county
of Bexar and State of Texas, have invented
a new and Improved Automobile-Pump, of
which the following is a full, clear, ad ex-
act description.
10 The invention relates to that form of au-
tomobile pump having means for attaching
it to an automobile wheel, and for actuat-
ing the pump by the revolution of the wheel
for the purpose of inflating .the tires.
15 An object of our invention is to provide a
pumping attachment of the character re-
ferred to, which is attachable to any wheel
regardless of the size and form of the hub,
or the absence of any projection of the hub
20 beyond the face of the wheel.
A further object is to provide means so
designed as to permit of securing the at-
tachment to such wheels as are provided
with large brake drums.
25 A further object is to simplify the con-
struction of pumps of the indicated char-
acter, to the end that few parts will be in-
volved, and whereby the 'attachment can be
secured to the wheel and detached there-
30 from quickly and conveniently.
The distinguishing features of the inven-
tion and the important structural elements
in the preferred embodiment which is given
as an example, will be more particularly
35 explained in the specific description herein-
after to be given.
Reference is to be had to the accompany-
ing drawings forming a part of this specifi-
cation, in which similar characters of ref-
40 erence indicate corresponding parts in both
views.
Figure 1 is a side elevation of our im-
proved pump and appurtenances, showing
the same in position for use; and Fig. 2 is
45 a horizontal section of the pump on about
the line 2-2 in Fig. 1, but showing the
member having the securing arms of the
attachment moved approximately 90 de-
grees from the position shown in Fig. 1.
50 In constructing-an attachment in accord-
ance with the illustrated example, a flat
ring 10 is provided, the open center 11 of
which is of a size to pass freely over any
hub of standard cars, the inner face 12 of
55 the ring being adapted to lie close againstthe outer face of the wheel 13. The ring
10 is provided with two or more arms 14
which extend preferably on radial lines ani
at diametrically opposite points. The arms
may be connected in any suitable manner 60
with the ring 10. In the illustrated example .
these arms are integral with the ring; they
extend to a point sufficiently distant from
the hub for the .ends 15 to reach beyond the
brake drum 16 of the wheel, regardless of 65
the size of said drum. The outer ends of the
arms 14 carry suitable means for clamping
engagement with the wheel; in the illus-
trated example the devices are adapted to
engage with the spokes 17 of the wheel, the 70
clamping device shown consisting of a
hooked bolt 18 having a threaded shank 19
that extends from the ends 15 of the arms
14, and carries lever nuts 20. The ring 10
supports a loose ring 21 carrying the 'air 75
pump 22, said- ring .21 in the illustrated ex-
ample being received on the reduced inner
end 23 of an outer ring .24, which is secured
to the ring 10. In the illustrated example,
the outer ring 24 is attachable to the ring 80
10 and readily detachable therefrom by
-means of screws 25 or their equivalents.
The outer portion of the ring 24 has a di-
ameter sufficiently larger than the inner re-
duced portion 23 to form a shoulder 26, so 85
that the said ring 24 constitutes a retainer
for the loose ring 21, and said ring 24 con-
stitutes an actuating member for the pump
22, and for this purpose' suitable teeth 27
are formed on the outer periphery of the 90
ring 24, so that the latter constitutes a gear
wheel which in the illustrated example is a
spur gear; it meshes with a pinion 28 that
is keyed to the inner end of the crank shaft
29, said crank shaft desirably operating in 95
the hollow base or crank case 30 of the pump
22, and being connected to the interior of
the trunk piston 31 of the air pump by the
piston rod or connecting rod 32. Advan-
tageously in the preferred form of the in- 100
vention as illustrated, the pump 22 is at-
tachable to and detachable from the ring 21
so as to dismember the parts to assemble the
same in small compass when not in use, and
to this end the loose ring 21 is formed with 105
feet 33 projecting outward parallel with the
axis of the said ring to constitute brackets,
and the base of crank case 30 of the pump is
formed with a flange 34 at each side, said
flanges being secured, as by bolts 35, to the 1101,054,762.
