.- Application filed May 21, 1am. seriaino. 769,101.

To all alien it may concern:

Be it known that-.1, HENRY PoLrrnMos, a citizen of the United States, residing at .liuffalo, in the county of Erie and State of \vhereliiy a proper circulation of air may be maintained and to further provide a sliding strip connected to the lowerextremities of the side walls which may be raised or lowered as desired. The sliding strip provides for a regulation oi heat of the ovenand also provides ventilating means therefor.

A further object is to provide an enameling oven which is suspended from an overhead trolley where'ev the said oven may be moved out of the way when not in use.

l Viiih the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement o f'parts and in the i details of constri-iction herema'lte'r described,

and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope oi" what is claimed, without departing from the spirit of themvention.

In the dra'iwings accompanying this specification and forming apart thereof, the preferable form of my invention is illustrated, in which Figure 1 is aside view in elevation of my improved ena-meling oven as suspended from an overhead trolley. Fig. 2 is a cross sectional viewthereot taken on the line-A--A o'f'Fig. 1 and with the end door of a somewhat modified form. Fig. 3 illustrates a section taken through one of the side walls and showing the manner in which the strip may be raised and held in such position. Fig. l illustrates a modified'form of side wall in which the sliding strip is omitted.

Referring to the drawings in which simibe maintained in a raised position. there are suitable bolts 9 soarrangeti that lar reference numerals designate corre sponding parts throughout the several news, the oven COlIlPl'lSBS the side walls 1 and the top 2 extending thereacross. As

illustrated in Fig. l of the drawings. the

side walls and top may be formed of the two metal plates 3 spaced a suitable dis tance apart and inserted thcrebetween is the heat insulating substance t.

As illustrated in Figs. 1, 2 and 3 ot' the drawings the side wall 1 is provided with a longitudinal strip?) slid-ably secured to the lower edge thereof by the guides 6 whereby the said strip may be raised or lowered,

there being suitable latches 7 adapted to err gage eyes 8 secured to the side walls 1 and strip 5 respectively, whereby the strip may Also the strip 5 may be. locked in its lower p0 sltion. The form of side wall illustrated'in Fig. 4C differs from the foregoing in the fact that the side wall 1 is projected dowi-iwardly or a slight distance and the strip 5 is dispensed with.

llingedly secured along the top of the oven and at the ends thereof are the swingingdoors 10 which act as'a closure for the oven ends and serve to retain the heat therein. The doors 10 are hingedly secured to the top as at 11 and in order to provide meanswhercbv the doors may beheld in raised and also an adjusted positions, a rope or flexible conncctronlZ is rigidly secured to the lower portion of the door as at 13 and extends over a superstructureM rigidly secured to the top of the oven and at the side edges thereof. The said flexible connection or rope 12 then extends dowmvardly and engages a. suitable tying post 1-5 arranged at a convenient point upon the side wall .1.

A somewhat modified form of door is illustrated in Fig. 2 oi the drawings in which the door is of the folding or collapsible type and comprises a plurality i li' vertical sections 16 hingedly secured together and hingedly secured to the side walls 1.

The said modified form of door is adapted to fold toward the center and is used when a number of cars are positioned adjacent and little or no room is available therebetween and an upwardly swinging door would be useless. A

The side walls of the oven are provided witha number of openings 17 extending therethrough and adjacent which openings lot are the flap valves .18 pivotally secured in position ,jvvinnh; flops ere adapted to regulste the tires of the exposed portion ofthe openings. ed

, vided at the top of the oven and act in con 'junction with the inlet openings 1? to n1smts out the oven,

A conventional type of thermometer or other temperature recording device 20 1s in a constant circulation of air through- ;illustrated upon the side wall of the oven and is adapted to register the temperature maintained therein. The strip 5 may be raised While the oven is moved about and also may be raised for the purpose of venti- --eting and cooling the oven should the temobrature thereof, rise to too high a point.

In order to mount the oven in a portable manner, the overhead trolley is provided and comprises the horizontal beams 21v sup-- ported upon suitable posts and upon which beams are mounted the wheels 23. A suitable suspending structure 2% is carried by the Wheels and rigidly secured to the top of the oven. The posts 22 which support the overhead trolleys are positioned the sides of the track rails 25 beneath which rails are disposed the heating coils 26, the

letter supplying the heat for the leaking of v the enamel. I

,With the above construction as I have described the same; the overhead track and hangers allow the oven to be moved about and brought over e'passenger car which is positioned upon the'rails 25 above the coils 2,6 and "the end doors 10 or "16 ii-re then closed and the ventilators 17 more adjust-c so that the temperature registered by the thermometer 20,

reach-es the desired said openings.

to it place Where the oven will take up little or no shop room. 7

Having thus iully descrlbed the invention what I chum to be new and orlginal with me 1s:- I
