To ZZ whom t may concern Be it-known that l, CHARLES l). YOUNG, a citizen of the United States, residing at Altoona, in thel county of Blair and State of Pennsylvania, have invented certain new and useful improvements in Drying Appadrying painted railway vehicles, and has for il xl its object to lessen the time and the cost now required to accomplish this end, as well as to improve the life. and appearance of the nished covering.

Vlith these and other objects in View, the invention consists in the novel details of construction and combinations of parts more ully'hereinaiter disclosed and particularly 'pointe-d out in the claims.

ti-Seri u to accompanying drawings orn'ring a part of this specification in which numerals designate like parte in all the t'fiewm-ligure l, is a diagrammatic cross sectional view in elevation, of an oven builtin accordance with my invention; Fig. 2,` is

a persnective detail view of a short pipe section; Fig. 3, is a cross sectional plan. view of the' arts shown in Fig. l; Fig. 4, is a iongitu inal sectional. View ot the parts shown in Fig. i Fig. 5, is a side elevational view artlybroken away of any oven; and Fig. `is a Vlongitudinal sectional plan View ci' the. arts shown in Fig. 5.

3. in 'eates the frame work preferably of steel and made to conform to the general shape 'of a ear, 2 any suitable doors for closing 'the oven during the baking operation, 3 tracks on which a vehicle i can be accommodated, 5 an inside lining preferably of steel plate, 6 an outer plate, and 7 any suitable insulation between the plates 5 and 6. The doors 2- insulated in a similar manner. `Along the interior walls of the oven l preferably lace a plurality of rows of steam pipe 9, fed from the branch supply pipes 10, joined to the main feed pipe 11 as shown. The pipe l0 may be further providedwith extensions la joining a plurality of mani folds l2, near the licor, and having tapped inte than?. at intervals short lengths of pipe 13, as best seen in Figs. Q, f3. By this means am able to provide a very large radiating surface, and with say a stema-pressure of one hundred pounds (100 lbs') l can maintain an 'oventemperature of 2500 l". Further my structure is such, as will be clear `from the drawings, that no metallic connections between the inner and outer 'surfaces of the oven are had, and therefore the loss of heat from the radiators is reduced to a minimum.

.ln order to provide for an efficient ventilation the structure has a plurality of preferably rectangular inlets or openings 16 near the floor, and a plurality of spaced ventilators l? of any suitable type in the roof?. By this means the fresh air which is necessary for 'the proper drying of the vpaint is had, while at the same time an exit is provided for the Volatile matter given olf.

18 represents suitable drain pipe, and 19 suitable tie members for holding'together the frames l and stifening the structure.

lt is essential in drying car bodies that the heat be evenly `distributed throughout.

For if the ends of the car for example, .dry

harder than the center, owing to a'higher temperature at the ends, the paint would blister, unless a different proportion of Vehicle be placed in the aint to be applied to the ends, which is,'o course, impracticable. My construction it will be seen, avoids these objections by providing a uniform temperae ture throu hout the length of the car. That is to say, provide for the admission of air along the bottom of the oven and' above the level of the rails, employing the openings or members 16 to assist the ventilation and equal distribution of the air. I also provide` ventilators at the top to insure the proper equal distribution of heat throughout. Further, the arrangement just described provides a circulation oi' air along the sides of the oven which causes the gases and depleted air to pass out.

In order that the operation of my invention may be clearly understood in `the case of a car it issaid A priming coat may be first given the car in the paint shop, whereupon it is moved into the oven and baked for say three hours, the temperature at first being say 160 F. whereupon it may be raised say 1 F. per minute until 250 F. is reached. The oven is now held at this latter temperature for the rest of the three hours, whereupon the car is'withdrawn, a1- lowed to cool sufficiently to work upon,-and its surfaces glazed and puttied where found necessary to lill up depressions and uneven -place'sl The car may nowl receive its first surfacing coat and be returned to the oven for three hours, baked as'before, be re- 5 moved, cooled and coated again. AThis may berepeated as often as desired, when the outside surface is finally i ubbed down with einery cloth and oil and the colors are applied. Each color coat may be baked as above, when the lettering, striping ete. is applied,

andthe varnish coatings are applied. latter coatings can be .iik'eu'ise baked, but it is preferred to begin the opration at say 1200 F. and to not let the temperature rise above say ,i500 I". Il`he interior oit the car is next rubbed to give it a AIlat .linish7 and the painting of the car is completed. All the above operations can be conveniently carried out with my oven in say from 20' six to eight days, while under the present system it would require from sixteen to eighteen days to aceou'iplish the same results. In addition to the above various paints and varnishes have now been prepared so they are especially adapted tor this baking process, and are found to have a greater elasticity, a greater durability, a better appearance and a longer liie than those heretofore applied in the old way. It follows from this that the baking process combined .vith these said paints and varnishes materially lessons the checking and cracking heretoliorc encountered, and as the work canbe done l. under standard uni'l'ornl conditions, uniform results are also-attained. 'Fui-ther, by uniformly heating the car in the first place and thoroughly drying the same before the liretl dpriming coat applied, all objectionable moisture is ren'ioved, and a far better hold I 40 is attained by saideoat than has been heretofore possible. In other \\'ords,before the adfor it aids in preventing the paintedsurface from going to pieces inaspots as heretofore. In addition to the above, not only does the coated surface have a longer life, a better appearance, and can be finished in a less time, but the material itself costs less with- Iout any extra labor charge.

These It is obvious that thoseskilled in the art 6 may vary the details of construction, as well as the arrangement of parts without departing from the spirit oft' the invention, and 1 therefore l" do not wish to be liinitedto the above. disclosure, except as may be required 6l by the claims.

1. In an apparatus for drying or baking a railway vehicle, the combination of a `chamber comprising a heat insulated cover- 7i ing; a door for saidehamber; a track on 'which said vehicle may enter said chamber;

-tween them; a door :for said chamber com- 85 prising two plate members with insulation between them; a track on which said vehicle may enter said chaniber;' openings for the admission of fresh air near .the bottom of said chamber; ventilators for the exit 0f 90 gases at the top of said chamber; and steam heating. means at the vsides and'bottom of` said chamber comprising a. plurality of pipe, manifolds and short lengths of pipe projecting :from said manifolds for producing any desired uniform temperature in said chamber, substantially as described.- l

23. In an apparatus for uniformly drying and baking railway vehicles throughout their length, the combination of a framework; a. heat insulated shell supported by said frame work; heat insulated doors closing said shell; a track for vehicles entering said shell; means for the admission of air along the bottom of said shell above said rails; ventilators at the top of said oven; and heat"radiati11g means along the sides of said oven; whereby a circulation of air along the saidsides is secured, to insure an equal distribution of tempe ature throughout and to carry away gases and depleted air, sub-- stantially as described.
