UllTED STATES PATENT FFIICEO
CHARLIE A. McNULTY, OF POWDERLY, TEXAS, ASSIGNOR TO GEORGE A. BONGE, OF
POWDERLY, TEXAS.
PIPE-PAINTING MACHINE.Specification of Letters Patent.
Patented Feb. 15, 1921.
Application filed March 25, 1920. Serial No. 368,487.
To all whom.it may concern:
Be it known that I, CHARLIE A. MCNIITY,
a citizen of the United States, residing at
Powderly, in the county of Lamar and State
5 of Texas, have invented certain new and use-
ful Improvements in Pipe-Painting Ma-
chines, of which the following is a specifica-
tion.
This invention relates to improvements in
10 devices for painting pipes or other elongated
substantially cylindrical objects.
The principal object of the invention is to
provide a device for painting pipes which
will accomplish its purpose as thoroughly
15 and efficiently as the hand and much niore
expeditiously, thus effecting a great saving
in time and labor.
Another object of the invention is to pro-
vide means for salvaging surplus paint so
20 that a minimum waste will take place when
operating the device.
For the purpose of illustrating this inven-
tion there is shown in the accompanying
drawings one form thereof which is at pres-
25 ent preferred, since the same has been found
in practice to give satisfactory and reliable
results, although it is to be understood that
the various instrumentalities of which the
invention consists can be variously arranged
30 and organized and that the invention is not
limited to the precise arrangement and or-
ganization of these instrumentalities as
herein shown and described.
In the drawings:
35 Figure 1 is a sectional side elevation of
the device showing to advantage the opera-
tion of the brushes upon a section of pipe.
Fig. 2 is a sectional end elevation of the
cleaning apparatus.
40 Fig. 3 is a detail view of the operating
mechanism therefor, for drawing the device
over the pipe to be painted.
Like characters of reference indicate :like
or similar parts throughout the several
45 views of the drawings in which:
A designates the cylindrical body portion
of the painting apparatus which is formed
of upper and lower complementary sections
1 and 2 having flanged edges. 3 through
50 which extend bolts 4 for securing the sec-
tions together about a pipe or other cylin-
drical object to be painted.
Tapped into .the upper section 1 of thebody is a paint receiving funnel B which
has mounted thereon intermediate its ex- 55
tremities a. trough 5 for receiving fuel, as the
paint can be applied more effectively when
warmed. The hand grip 6 on the funnel is
guarded by a projection 7 so that the flames
from the trough will not contact with the 60
hands, of an operator. In connection with
the heating apparatus it is pointed out that
a very small flame is employed for the pur-
pose and very little fuel.
Mounted through the medium of rivets 8 65
in each section of the body are a plurality
of semi-circular complementary ribs 9 car-
rying bristles 10 which engage the pipe to
be painted, and two pairs of the ribs are
arranged in front of the entrance of the fun- 70
-nel B therein and preferably three or more
pairs to the rear thereof.
Arranged below the body is an elongated
tank C for receiving surplus paint, which
passes from the body through the opening 75
11, and an outlet opening having a cover 12
permits of removal of the surplus paint
therefrom for reapplication to the pipe.
Mounted forwardly of the body A is an
operating device comprising supporting legs 80
13 and a reinforcing leg 14 which engages a
shaft 15 journaled through the upper ends
of the supporting legs 13. Mounted on the
shaft 15 between the legs 13 is a drive cog
16 over which fs trained a chain 17 engaging 85
a driven cog 17a on a shaft 19 journaled
intermediate the extremities of the legs 13.
A drum 20 is also fixed to the shaft 19 about
which is wound a cable 21 the free end. of
which is attached to a 'removable collar 22 90
secured to the pipe to be painted. An oper-
ating handle 23 is keyed to the end of the
shaft 15 and the legs 13 and 14 are secured
to the body as illustrated, so that upon at-
taching the collar 22 to the pipe to be paint- 95
ed the drive cog 16 is actuated by turning
the handle23 so that the cable 21 is wound
upon the drum 20 and the painting device is
drawn along the pipe. In operation the
paint' is poured into the funnel and is 100
warmed by the heat from the fuel in trough
5 and the operator supports the apparatus
in position by grasping the hand grip 6.
In order to positively maintain the device.
in proper position upon a pipe or pole 105
there are arranged in the body forwardly1,368,g16.
