SPRAYING CABlNET.

Application led September 8, 1924. Serial No. 736,420.

This invention relates to a ,spraying cabinet or booth and is particularly concerned with a novel construction for and method of reclaiming the material sprayed whichdoes not adhere to the object against which it is sprayed and which, heretofore, has

fallen. to the floor either within or out- -side of the booth' or has been carried by air currents through pipes leading from the booth to an exhaust stack, with a consequent waste of a considerableportion of the material. It is an object and `purpose of the present invention to provide a spraying cabinet or booth and equip ,it with means whereby all or nearly all of the material heretofore wasted may be reclaimed for future use. The invention consists in novel constructions and combinations and arrangements of parts for practically etfecting thls end as well as many others not at this time specically stated, but

which will appear .as understanding of the invention is had from the .following description taken in connection with the accompanying drawings, in which,

Fig. 1 is a vertical section through the spraying boothand exhaust stack, parts o the construction being shown in side elevation `and broken away lto illustrate interior mechanism. C

Fig. 2 is a vertical section through the outlet stack and the reclaiming cabinet or chamber in the lower end thereof, the section being taken longitudinally of said cabinet or chamber.

Fig. 3 is a horizontal section through the Fig. ,4 is a front elevation of the cabinet P ber, the top 14 of such chamber having an with a part thereof broken away to show the upper outlet nozzle.

Like 'reference characters refer to like parts in the diderent views of the drawings.

The cabinet, in which the spraying o material upon the article to be coated occurs, may be madeof sheet metal or other suitable material and includes a back 1,

sides 2,-top 3 and bottom 4 of rectangular outline, the same beingsubstantially square in outline. The front of the cabinet is open therebeing, however, a downturned up r lip-1,5 to thev front edge of the top 3 which partially closes the front of, the cabinet at itsnpper side and a shorter upturnedY 11p 6 at the front edge of the bottom 4, this lip, in conjunction with the sides, back and bottom forming a pan in which a fluid, indicated at 7 may be held. A table 8 or other suitable support for the articlel 9 to be e0 sprayed is located within the cabinet being supported on suitable standards 'as shown. The article 9 may be anything which is to receive a coating. One place where this spraying booth has been used is in vcoating a5 refrigerator linings onthe inside withsuitable porcelain material which is sprayed thereon, the lining with the porcelain thereon being afterward baked in a suitable oven in accordance withy the well-known proc- 7o esses of bakingporcelain -onto sheet metal.

Back of the cabinet 1 is an enclosed reclaiming chamber having front and back vertical sides 10 and 11, a bottom 12, ends v13 anda top 14. A. vertical partition 15 ex- 'I6 tends transversely between the front and back from the bottoma little over half way to the top; and at each side of this partition a sheet metal vane 16 extends from the top downwardly and vinwardly toward the partlso Vtion 15, the lower edges of the vanes 16 extending to a plane below the upper edge of the partition 15, as shown in Fig. i2, there being spaces between'the lower edges of the vanes and said partition. A liquid 17 is also g5 held in the reclaiming chamber. When the cabinet or booth is used in covering sheet metal with porcelain the liquid at 7 and 17 is water, this being aA solvent of the material used. If varnish or other like material is sprayed upon an article within the cabinet a suitable liquid solvent for such spray material is used instead of water, as is evident.

A vertical stack 18 of sheet metal is suported on and abovethe reclaiming chamopening so as to make communication between the interior of the chamber and the interior of the stack. The lower end of the f .stack is located between the upper edges of mg the vanes 16. 'A pipe 19 is positioned horizontally above the top 3 of the cabinet, at its rear end passing through the front side of the stack 18 and being curved upwardly, as indicated at 19, while its front end is 105 curved downwardly, as indicated at 19", and

joins with a suitable nozzle 20 open at its under side and located within the upper front ortion of the spraying cabinet. Intex-mediate the ends of the pipe 19 a fan 21 squarely against the inner or bottom Wall of the said Socket. rhe operator then uses a hammer7 striking the outer plug in the direction of the length of the axle whereby the Wheel is jarred loose from the a-Xle and Jche key thereof and may be quickly removed.

Having described the invention what is claimed is- A device adapted to be used for removing' a Wheel from un axle upon which it is keyed comprising a body provided at its opposite ends with ulined Sockets of different sizes, `fand anvil plugs itting in the sockets.

In testimony whereof I affix my signature.

and having its lrear end extending through the front side of said stack, anozzle located in the upper front portion o the cabinetv nozzle into said pipe and thence pass into the stack, substantially as described. n

4. In combination, a cabinet having an open front side `and adapted to receive articles therein for spraying the same, suction nozzles located in the cabinet, one at each side thereof and one at the upper front portion thereof, pipes connected to said nozzles, a vertical stack located back of the cabinet and connections for carryingair through the pipes to saidl stack combined with means for drawing currents of air through the pipes rearwardly, said nozzles at the sides of the cabinet having inturned ends whereby the openings in the said ends of s aid nozzles are positioned oppositely to each other, and the upper nozzle having an open lower side, substantially as described.

5. In combination the elements .defined in combination in claim 7 combined with means for adjustably coupling said nozzles at the'sides of the cabinet to their respective p ipes for adjustment from front to rear and vice versa.

In testimony whereof I aiix my signature.
