4 ATTORNEY Patented Dec. 9, 1930 UNITED STATES LEON T. MART, 01" KANSAS CITY, MISSOURI SPRAY-COOLING Dawes v Application filed August 30, 1928. Serial No. 302,969.

M invention relates to devices for cooling hquids and more particularly to means associated with a spray nozzle for enhancing contact of air with the sprayed liquid to cool the same, comprising a tube concentric with the nozzle and through which air currents are induced.

The principal object of the invention is to provide an improved and simplified tube support which automatically self centers the tube with relation to the spray nozzle to assure flow of induced air currents through the spray.

In accomplishin this and other objects of the invention I ave provided improved details of structure the preferred form of which is shown in the accompanying drawings wherein:

Fig. 1 is a sectional perspective view of the preferred embodiment of my invention as installed on a spray nozzle.

Fig. 2 is a plan view of the installation illustrated in Fig. 1.

Fig. 3 is a perspective view of the tube supporting bracket.

Fig. 4 is a perspective view of a preferred type of nozzle with which the device is associated.

Fig. 5 is an enlarged vertical sectional view through a portion of the nozzle and the supporting bracket illustrating the method of mounting the bracket on the nozzle.

Referring in detail to the drawings:

1 designates the discharge pi from a hot liquid source and 2 the nozzle or dispersing the liquid in the form of conical spray as indicated by the lines designated 3, the nozzle being preferabl provided with a peripherall extending ange 4 forming a shouldere seat 5 for mounting the tube supportin bracket 6. a he bracket 6 is preferably a metal casting and comprises a hoop or ring 7 connected to a concentric collar 8 by radially extending arms 9. The collar 8 is provided with a bore 10 of a diameter to fit snu ly over the body of the nozzle and has a at lower side 11 which seats on the nozzle flange 4 as best shown in Fig. 5. Thus the ring is supported concentrically with the nozzle and in fixed relation thereto, to support the air delivery tube 12 in correct relation to the discharged 160i the sheet may be lapped asat 17 and secured by fastening devices such as bolts 18 to retain the tube in clamping relationfwith the hoop 7 of the bracket.

The tube '12 is open at both ends to atmosphere, and is of sufficient length to provide proper flow of induced air currents through the sprayed fluid and is supported so that the periphery of the spray, thatis the path taken by the extreme exterior particles of liqbuid, slightly clear's'the upper edge of the tu e permitting unimpeded, discharge ofthe spraybut which in effect closes ofi the entire area of the tube to provide efficient flow of air'through'the'spray to cool the same.

Thus it is important that the tube be correctly positioned vertically with relation to the spray and that the spray is concentric with the tube.

The vertical adjustment is calculated by positioning of the groove 13 so that when the tube is assembled on the supporting hoop, its upper edge is properly positioned with the cone and since the hoop is supported concentrically with the nozzle by the radial arms projecting from the collar 8, the tube is antomatically self centered when assembled onthe nozzle.

In assembling the device the tube is clamped about the support so that the groove 13 receives the hoop 7 which retains the tube in vertical axial alignment with the axis of the bore 10 of the collar 8. The supporting bracket is then positioned so that the collar slips over the body of the nozzle and rests on the flange 4, the collar having sufficient bearing with the nozzle to prevent lateral movement with relation to the nozzle.

Thus it is apparent that when the tube is positioned on the nozzle, the tube is automatically self centered without further adjustment and that the tube is firmly supported without other anchoring means whereby flow of air through the tube is induced and the air contacts all portions of the spray cone substantially equally to cool the same.

lVhat I claim and desire to secure by Letters Patent is:

1. In combination with a spray nozzle and an air delivery tube having an internal peripheral groove, a bracket for supporting the tube from the nozzle comprising a collar for receiving the nozzle, a hoop for-engaging in said groove of the tube and radial arms connecting the collar with the hoop.

In combination a spray nozzle having a peripheral flange concentric with the nozzle outlet, a collar supported on the flange, a hoop, arms supporting the hoop in concentric relation with the collar and an air delivery tube supported by the hoop.

3. In combination a spray nozzle having a stop shoulder, an air delivery tube having a peripheral internal groove and a bracket for supporting the tube concentrically of the nozzle comprising a collar engaging the stop shoulder on the nozzle, a hoop received in the groove in the tube, and arms connecting the collar with the hoop.

4. In a device of the character described, a nozzle having an annular shoulder, a bracket including a collar seatable on said shoulder, a hoop concentric with the collar, and means rigidly connecting the hoop with the collar, and a metal member having a groove and adapted to form a tube having an inner groove receiving the hoop for centering the tube on the nozzle.

In testimony whereof I allix my signature.
