Description

J- R. DICKENS ET AL AIR HEATER Filed Jan. 22, 1926 W/ZZ Patented Aug. 9, 1927.
UNITED STATE 1,638,18? ATENT, joFFics. 1
JAMES R. DICKENS, ERNEST O. HARRIS, AND THOMAS A. WARNER, OF THOMASVILLE,
NORTH CAROLINA.
AIR HEATER.
Application filed January 22, 1926. Serial No. 83,157. i.
The present invention has reference to an apparatus especially designed for use in connection with a varnish spray and aims to provide means whereby warm air will be I delivered to the spray to cause the varnish to spread more evenly.
A further object of the invention is to provide means whereby condensates may be drawn off at the bottom of the main tank.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawings:
Figure 1 is an el-evational view of a device constructed in accordance with the invention.
Figure 2 is a longitudinal sectional view through the device.
Figure 3 is an enlarged fragmental sectional view through the discharge end of the air supply nozzle.
Referring to the drawing in detail, the device includes an elongated upright body portion 5 which is cylindrical in formation and having threads at its upper and lower ends to receive the caps 6 and 7 respectively.
Extending into the body portion 5 at the base thereof is an air supply pipe 8 which is fed with air through the pipe 9 which is supplied with a thermometer 10 to register the heat of the air passing into the body portion so that the temperature of the body portion may be regulated to meet various requirements.
This pipe 8 is provided with threads at its upper end to receive the cap 10, which cap acts as a support for the cone-shaped deflector 11, which is shown as having its lower edge terminated an appreciable distance below the cap 10.
Mounted above. the deflector ll'is a plate 12 which is secured to the cap by means of the bolt 13, the cap and plate acting as a means for holding the deflector 11 in position. Openings indicated at 14 are formed in the pipe 8 adjacent to the upper end thereof, which openings permit air to ex haust from the pipe 9.
Above the discharge end of the pipe 8 is a heating coil 15 which connects with a suitable source of steam supply, through the pipe 16, there being provided a valve 17 for controlling the passage of steam through the pipe 16.
Steam circulates throughthe coil 15 and passes from the coil through the pipe 18' where its passage is controlled by means of the valve 19.
A suitable gauge indicated at 20 communicates with the interior of the body portion so that the pressure of the air within the body portion maybe determined at all times, while the thermometer 21, which is supported adjacent to the upper end of the body 5, registers the temperature of the air within the upper portion of the body 5. The air which has been heated by its passage through the body portion may pass from the body portion through the pipe 22 where the air may be supplied to a suitable spraying device not shown, the air having been dried and heated causing the varnish with which the sprayer is filled to spread evenly.
The reference character 23 indicates a gauge mounted adjacent to the lower end of the body portion so that the condensation within the body portion may be determined, and when the condensation is too great, the liquidmay be drawn off through the waste cock 24.
, From the foregoing it will be obvious that air under pressure may be forced through the pipe 8 whereupon the air passes from the pipe through the openings 14 from where the air is forced downwardly under the member 11.
After the air passes downwardly under the member 11, it will be obvious that the air will rise within the body portion pass-. ing between the lower edge of the member 11 and inner wall of the body portion where it will contact with the plate 12 and be forced laterally, from where it passes upwardly around the heated coil 15., which causes the air to become heated prior to its passage to the varnish sprayer.
W e claim:
I11 a device of the character described, an elongated body portion, a feed pipe extendwith the openings, a cone-shaped deflector positioned over the cap, a plate contacting With the cone-shaped deflector, means for securing the cap, cone-shaped deflector and plate together, said cone-shaped deflector and plate having their edges spaced from the inner surface of the elongated body portion to permit air to pass upwardly through the body portion, and a heating 'coil positioned Within the elongated body portion above the cone-shaped deflectorand plate to heat the air passing through the bodyflportion.
In testimony that We claim the foregoing as our own, We have hereto natures. V JAMES R. DICKENS.
ERNEST O. HARRIS.
THOMAS A. VARNER.
