NOZZLE.

ASpecification of Letters Patent.

Patented Dec'. 14, 1920.

Application led July 7, 1919. Serial No. 309,220. I

Dallas,`in the county of Dallas and State. of.

Texas, have invented certain new and/use- 'ful Improvements in Nozzles, of which the following is a specification.

My invention relates to a nozzle for use in supplying a liquid paint remover to a painted surface; also for supplying steam as well as sand or the like, either separately or together as desired.

An important feature is 'the provision of means whereby steam under pressure may be utilized to propel or eject either the paint removing liquid or sand upon the surface to be treated, the steam also serving to preheat the liquid.

In carrying outv the invention a body is provided with separate connections from sources of supply of steam, chemical and sand or equivalents and means for controlling the passage of each of these through the body. A barrel is mounted on the head and the steam is delivered into the'barrel ahead of the discharge points of the liquid and sand so as to create a suction and draw the said materials from their passages and into the barrel. y

The invention will be more readily understood from a reading of the following speciiication and by reference to the accompanying drawings, in which an example of the invention is shown' and wherein:

Figure 1 is, a side elevation of a nozzle embodying the invention,

Fig. 2 is a partial longitudinal sectional Fig. 3 is a cross-section on the line 3-3 of Fi 2.

ign the drawings the numeral 5 designates a head or body provided with a` reduced portion in which a chamber 6 is formed. The head has a screw threaded collar 7 which lreceives the flange 8 of a forwardly tapered barrel 9; whereby a joint is formed permitting the barrel to be removed.

The head has a central steam passage l() with a chemical passage 11 on one side and a sand passage 12 on the other side. said passages all being substantially parallel. Each passage has a tapered seat 13 at thev rear end of the head to receive a corresponding nipple 14 provided on a disk 15 which has extensions 16 of the nipples on its opposite side. A steam hose 17 is attached to the center extension, a chemical hose 18 to one ofthe other extensions and asand hose 19 is attached to the other extension, the hose 18 and 19 being attached so as to communicate with the passages 11 and 12 respectively. A coupling collar 20 surrounds the disk and has screw threaded engagement with the rear end of theyhead as is shown in Fig. 2. By tightening the collar the disk is drawn register withthe passagethe plug being gwen a quarter turn to close the passage.

\Each plug has an enlarged body 22 seated in the head 'and projecting into an externally threaded collar 24 on the surface of the head. A packing cap 25 is screwed on each toward the head and the nipples lc'forced collar 24 and surrounds the stem 26 of the y valve. The How through any passage may be cut off or controlled by turning the valve thereof.

From the passage 10 a steam tube 26 eX- tends a short distance into the barrel 9. A tube 27 extends from the passage 12 into the collar 7; while a tube 28 extends from the passage 11 and terminates also in the said collar. The steam tube extends beyond the other tubes so as to create a suction to draw liquid and material from the other tubes. Vhere it is desired to discharge the liquid without the use of steam, an extension tube 29 is screwed onto the end of the tube 28and terminates beyond the end of the-barrel so that the chemical will not run back into the barrel.

The operation of the device or nozzle is as follows:

The steam valve 21 is suitably opened to admit'the desired volume of steam under pressure into the nozzle, which travels forwardly 'therein at a rapid speed. When the passage 11 is opened, the liquid chemical or paint remover will be drawn into and through the tube 28 by the suction created by the discharging steam at the forward end ofthe tube. This steam also preheats the liquid chemical before it discharges from the tube 28. When the passage 12 is opened,

the nelydivided abrasive material, such as tinev thoroughly dried sand, is sucked into and through the tube 27, and discharged through the barrel together With the steam. The nozzle is now brought in proximity to the painted surface to be treated. The mass discharging from the nozzle now impinges against the painted surface, and is found to thoroughly remove the paint therefrom or clean the same as the case maybe.

It is to be understood that the sand may be used in conjunction with the chemical or the latter may be cut off and the steam and sand only used.

Both the sand and steam may be cut off and .by using the extension tube 29 and elevating the chemical supply, the said chemical may be fed by gravity. When steam isused with the chemical the tube 29 is removed.

What I claim, is:

l. Infa nozzle, a head having passages therethrough, an attaching element secured to the head and having conduits communicating With the passages of the head and arranged to bev attached to Huid lconductors, valves in the head bisecting the passages, a

barrel joined onto the head, one of the passages of the head being for the introduction of steam, a tube extending from the steam passage of the head into the barrel, and other tubes extending from the other passages and terminating short of the steam tube.

Q. In a nozzle, a head having passages therethrough, an attaching element secured to the head and having conduits communieating with the passages of the head and arranged to be attached to fluid conductors, valves in the head bisecting the passages, a barrel joined onto the head, one of the passages of the head being for the introduction of steam, a tube extending from the steam passage of the head into the barrel, and other tubes extending from the other passages and terminating short of the steam tube, and an extension tube attached to one of the last named tubes and projecting from the barrel.

In testimony whereof I aix my signature.

DAVID P. CLEVELAND.
