Application led' July 6,

This invention relates to electric heating devices and is directed more particularly to an electricheating and ydrying device for printing presses. l ,y

'5 rThe primary object-of the present in- `vention is to' provide a heating and drying devicer whichr shall be particularly suited for presses havingl a reciprocating vbed'or other movable element over which ythe 1o Aprinted matter is adapted to pass'. The rde-y vice in this instance is desi1 gned as an attachnient to such bed or element so as to be movable therewith and'inclding means forcreating aniair draft over the'heating element la and against the sheet toy be dried. Another object isv to provide a yheating and drying K device of rthis `general character which shall be simple in constructioinin-K' expensivey to manufacture, and `which rshall be highly etlicient and durable in operation. `With these and otherobjects in view]` the invention consists ot' the various novel teatures Voit construction and arrangement or combination, all of'which will betully de- 26 scribedhereinafter and pointed out' in the appended claims e 'y In the drawing accompanying and formin part of this application:y

igure' 1 isa top plan view of a heater constructed in accordance with my invention;

Figure 2 is an enlarged transverse sectional view taken on theline 2-2 ofk Figurelgandl Figure 3 is an enlarged fragmentary top r plan view of the heater.,

these supports are slig tly arcuate inv conf-x tour so that a sheet of material resting thereon will be positioned above the heatingele- 60 ment andr hence avoid any danger of burning-or scorching ther-eci Each support is formed with a recessed portionr adjacent the bottom thereof which defines reversely disposedy arcuate edgesk 5 and 'feet 6 having 1925. Serial N0.' 41,632.

downwardly and inwardly inclined edges T. In assembling a heating and drying device ot this type, I provide a pair ot' side bars 8 and arrange a suitable number ot' supports l therebetweei'i in accordance with the length of device that is desired. These supports and bars may be fastened together by screws 9 inserted through one side bar and a support and threaded in the opposite side bar as indicated in dotted lines in Figure 3.

In order to create an air draft over the heating element and against the sheetk or other object to be driedand thus greatly expedite the drying thereof74 I position a sheet metal detlector platefl'O in Contact with the reversely disposed arcuate edges oit the supports as clearly shown in Figures 1 and This plate is preferably formed troni sheet aluminum to utilize the polished surtace thereof as a reflector` and thus increase the efliciency ot the device. n plurality oi bolts V11 extend through offset lugs 1B ou the supports and also through the detlector plate, and these bolts are each itted with a washer 14 and a nut 15 to. retain said plate in contactwith edges '5. The side edges of the detlector plateare retained in position bythe downwardly andl inwardly inclinedA edges 7r of the supports.

The heater is fastenedy transvereeljl ot the bed,v or other reciprocating part of the press, by-brackets 16 that are clamped to a rod 17 or other suitable support onthe press. The ends of the heating element are connected to a terminal block 18 that is fastened between the ends of side bars 8, so that such element may be easily and quickly connected to a source of electric current. In

Figure 2 I have shown each support pro'-A vided With apertures 19 so that a third Wire (not shown) may be connected at the mid point of the heating element to provide a variable heat control in the usual and Wellknown manner.

In operation. the heater being ydisposed Y device, and such draft serves to support the printed sheet during its passage thereover. It the press should stop While a sheet is passing over the heater, the rounded upper edges of the supports l would prevent the sheet 'from coming in contact with the heating elements or close enough to prevent serions injury or lire.

"Vhile i have described my heater as being particularly suited tor presses having a reciprocating hed so as to he movable there with, it will he obvious that it may he lastened to a stationary parl ot the press: and

etleet the drying hy direct radiation and such natural air dra'l't as would he created hy the heated element il.

What I claim is:

l. A heating' and drying device comprising a plurality of supports iornied troni tireresisting material, an eleetriiA heating element carried hy said supports, and a detleetor plate arranged heuer-ith said heating element and adapted to direct an air draft over said heating elenieut upon movement ol said device.

2. A heating and drying device comprising a plurality ot' supports loriaed troni tireresisting material, an elec heating elenient carried hy said supports. and a delleotor plate arranged beneath .said heating element. said plate having revY 'seiy disposed curved portions adapted to urea-ie an air draft over said heating element upon movement of said device in opposite directions.

3. A heating and drying device comprising a plurality of supports formed from tireresisting material, an eleetrie heating element carried by said supports, side hars eonnecting said supports, and a delector carried by said supports and spaced 'from said side hars for directing an air draftover said heating element upon movement of said device.

4f. A heating and drying device comprising a plurality et supports formed 'troni lireresisting material, said supports having apertures therein adaptel to receive an electric heating element and said supports each having an a reunie upper edge, side hars con neciing said supports, and a rellector arranged heneath said supporta.

A heating and drying device compris-- ing a plurality ot supports torined Ytroni lireresisi'ing material, said supports each ha ring an arcuate upper edge and apertures intersecting said edge adjacent each eud thereof, an electric heating element positioned in said apertures, and ineans tor detiectiug an air draft upwardly through said device and about said heating element upon niovenieut ol said device.

(i. A heating' and drying device. comprising a plurality o'lE supports l'ornied from lireresisting material` each of said sui'iports havingl apertures therein to receive an electric hea ,ing eleineiu and a recess therein defining reveisely disposed arcuate edges, and a dee dect r plate having reversely disposed curved portions seated against said edges.

T. A 'ireating` and drying device comprising a plurality ot supports i'orined from ireresisting material, each of said supports having an arcuate upper edge and apertures in terseciing said edge adjacent each end thereoli, a heating element positioned Awithin .said apertures, side hars connecting said supporte, and a curved deileetor plate arranged heneath .said heating element and spaced i'rorn said side hars.

In testimony whereo'l I aliix my signature.
