CHARLES D. LOVELACE, OF SAN ANGELO, TEXAS.
TIRE-INFLATING PUMP.Specification of Letters Patent.
Patented Nov. 12,1918.
Application filed February 7, 1916. Serial No. 76,593.
To all whom it may concern:
Be it known that I, CHARLES D. LovE-
LACE, a citizen of the United States of
America, a resident of San Angelo, in the
5 county of Tomu Green, State of Texas, have
invented certain new and useful Improve-
nents in Tire-Inflating Punmps, of which the
following is a full, clear, and exact descrip-
tion, reference being had to-the accompany-
10 ing drawings, forming a part of this speci-
fiaatrobi.
My invention relates to a pumping device
for inflating automobile tires. The pre-
ferred form of the invention comprises a
15 piump having an operating wheel adapted
to engage a drive wheel of an automobile,
and means for securing the pump to an auto-
mobile at a point near the drive wheel. One
of the objects of the invention is to produce
20 a simple and efficient means for forcing the
operating wheel of the pump into engage-
ment with the drive wheel. Another object
is to provide an adjustable attaching device
whereby the pump may be secured to an au-
25 tomobile at different points, so that the op-
erating wheel of the pump may be located
at a point where it will firmly engage the
drive wheel of the automobile. The adjust-
able attaching means is so constructed that
30 the pump may be applied to different auto-
mobiles.
With the foregoing and other objects in
view the invention comprises the novel con-
struction, combination and arrangement of
85 parts hereinafter more specifically de-
scribed and illustrated in the accompany-
ing drawings wherein is shown the pre-
ferred embodiment of the invention; how-
ever, it is to be understood that the inven-
40 tion comprehends changes, variations and
modifications which come within the scope
of the claims hereunto appended.
Figure I is a side elevation, partly in sec-
tion, illustrating a' pump constructed in ac-
45 cordance with the invention and also show-
ing portions of the running board and trac-
tion wheel of the automobile to which the
pump is applied.
Fig. II is an inverted plan view of the
50 pump shown in Fig. I.
Fig. III is a detail view of a hanger
whereby the pump is secured to the automo-
bile.
The pump comprises a web 1, bearings 2
55 depending therefrom, and a cylinder 3 pref-
erably formed integral with said web. Thecylinder is open at one end to receive a pis-
ton 4, and provided with intake ports 5 at
points intermediate of its ends. The closed
end of the cylinder is provided with a con- 60
section 6 to which a hose, or the like, may
be attached to conduct compressed air from
the cylinder to the tires that are to be in-
flated. The connection 6 contains a check
valve 7. 65
The piston 4 is adapted to open the intake
ports 5 as shown in Fig. I, and it may be
moved toward the discharge end of the cyl-
inder to compress the air and discharge it
through the connection 6. 8 designates 70
friction wheels separated from each other
to form a double drive wheel as shown in
Fig. II, and rotatably fitted to stub shafts
9, the latter being secured to the bearings
2. A piston rod 10 is pivotally connected to 75
the piston at 11 and secured to the friction
wheels 8 by means of a crank pin 12. This
crank pin is mounted in both of the friction
wheels and it extends transversely through
the piston rod as shown in Fig. II. Each so
friction wheel 8 is provided with a rounded
periphery adapted to engage the tread of a
traction wheel of an automobile. When the
'pump is in operation its friction wheels 8
frictionally engage the tire 13 of a rear 85
wheel of the automobile, as shown in Fig. I.
The adjustable attaching device, whereby
the pump is secured to the automobile, com-
prises a hanger 14 attached to the underside
of the running board 15 at a point near a 90
traction wheel of the automobile. The
pump is provided with an attaching flange
16 which extends upwardly from the web
1, said attaching flange being adapted to
enter a bifurcated portion of the hanger 14. 95
A series of pivot-receiving holes 17 is
formed in the attaching flange 16, and a
pivot pin 18, fitted to the hanger 14, is
adapted to pass through any one of the
holes 17. It will be noted that this adjust- 100
able attaching means allows the pump to be
located in several different positions with
respect to the traction wheel, the object be-
ing to provide means for securing the pump
to different automobiles. The pivot pin 18 105
may be readily withdrawn from the attach-
ing flange 16 and hanger 14, and the pump
may be very easily secured to the automo-
bile by means of this detachable pivot pin.
The pivot pin is preferably secured to the 110
pump by means of a chain 19.
