To all lwhom it may conccm:

Be it known that I, ANNE J. KLUEVER, a citizen of the United States residing at Lakewood, in the county of duyahoga and State of Ohio have invented a certaln new and useful Improvement in Heaters, of which the followin is a full, clear, and exact description, re'erence being had to the accompanying drawings. l

. This invention relates to heaters anQl dryers and is directed more -particularly to a heater and dryer for use inconnection with printing presses land the like.

The primary object of the present invention is to provide an electric heater which shall quickly and thoroughly dry the printed` material as it passes-through the press and thus prevent the inkon a printed sheet from backsetting on an adjacent sheet of printed material.

Another object is to provide a device 'of this character which shall be capable of directing the heat upon the material as it passes through the machine and dispel'and prevent the formation of static electricity thereon so that the material may be easily handled andl neatly piled.

Another object 1s to provide a heater and dryerv for accomplishing the foregoing results which shall be simple in construction, inexpensive to manufacture, and which shall be capablewof emittin the required heat for long continuous periods or intermittent service involving frequent heating and cooling of the heating element, without deterioration.

A still further object is to provide means for simultaneously breaking the heater circuit when the press is stopped, thus avoid-ing the possibility of burning or otherwise damaging the material which might be passing the heater at the time the press is stopped.

With these and other objects in view, the inventionv consistsin the various novel features of construction or arrangement and combination, all of which w-ill be fully described hereinafter and pointed out in the appended claims.

In the accompanying drawing wherein I have shown certain illustrative embodiments of m invention, Fig. 1 is an elevation of one orm oofpmy heater; Fig. 2 is a transverse sectional view taken 0n the line 2 2 of .Fig. v1; Fig. 3 is a. detail sectional view taken. on the line 3-3 of Fig. 1;'Fig. 4 is s an elevation of a modified form of heater;

sheet metal and provided with a back 2 and sides 3. Secured within this casing .and spaced from the back 2 is a partition plate 4 which is fastened to the sides 3 in any suitable manner as by means of bolts 5. The partition 4 and back 2 define a space therebetween as indicated at 6 which is filled with a suitable heat insulating material 7 such as asbestos. A corrugated plate 9 is vplaced against partition 4. As shown in Fig. 2, the

. peripheral edges of the sides 3 of the casing are defiected over the edges of the corrugated plate 9 and partition plate 4, and in this manner serve to secure these elements together.

The corrugated plate defines a series of longitudinal grooves 10 in which are fastened a plurality of supports 11 which `are adapted to su port a heating element indicated at 12. ach of these supports consists of a sheet metal bracket 13 whlch is riveted to the corrugated late, and is provided with an insulating bus ing 14 which is capable of withstanding high temperature and also electrically insulatlng the heating element from said bracket.

Suitable insulated terminals 15, 15 are mounted in one end of the partition late 4 and serve to secure each end of the eating element 12. These terminals are electrically connected with a pair of pins 16, 16 which are electrically-insulated from the end of the casing 1 through which they project. A separable connector block 18 is adapted to receive the pins 16, 16 in the usualV manner and establish electrical connection therewith. A conductor 19 extending from the source of current supply to the block 18 has connected'therewith, a 'suitable thereof which are exposed to the heat, so

preferably enamel the metal parte that the heat Waves will be reflected rather than absorbed. The enamel also serves to securethe insulating bushings 14. in the sheet metal. sup orts 13. l

Referring to igs: 4 and 5 it will be seen that I have shown a modified form of con' struction wherein indicates a suitable casin which has secured therein a semicylin 1cal reflector plate 26. This plate is preferably formed from a metal capable of receiving a high polish, such as copper, so that efiicient radiation of the heat will be obtained from a heating element 27 supported therein by suitable transversely arranged insulating bars 28.l These bars are secured in position by suitable brackets 29 which are fastened to the sides of plate 26 by bolts 30 which extend through said plate and also through the heater casing 25 and fasten said parts together. As shown in Fig. 5 the reflector plate 26 is spaced from the casing so that heat insulating material indicated at 31, such as asbestos, may be placed therein.

In practice a-heater of this general type is usually supported by a suitableV bracket vradiate on the fpress so that the heat therefrom is to the printedfmaterial as it passes through the press. This' may be accomlished by arranging the heater above or beow the printed material but I preferably positionv a heater of this'type above the l printed material so that the heat will be radiated directly to the printed side thereof. vrlhe press is usually fitted with a gear i' shift lever 35 such as shown in Fig. 6 and in order to prevent the operator from stopping the press without breaking the heater circuit, I interpose a switch, indicated 36 1n the heater circuit. This switch is connected with lever 35 through a pair of links 317-37, the inner ends of which are slidably connected with each other and a spring 38 is interposed therebetween. vThis connection permits the4 lever 35 to be moved a l greater distance than the switch lever so thatp when' the operator throws lever 35 to a neutral position to stop the ress, the switch lever will be disconnected rom its contact and the heater circuit broken. When lever 35 isrotated to operate the press, the switch will automatically close and bring the heater in operation.

Having thus described my invention, what series of parallel grooves, and heating ele.

ments disposed within said grooves'.

i 3. In a heater of the character set forth, the combination with a casing, of a corrugated enameled reflector plate arranged withinvand spaced, 'from said casing, heat .insulating material interposed between said reflector and casing, a plurality of heatin coil supports secured to said reflector, an

heating coils carried by said supports andv arranged in the corrugations of said reflector.

4:. In a heater of the character set forth, the combination with a casing, of a partition plate arranged within said casing, a portion'of said partition plate being spaced from said casing, heat insulating material cof interposed between saidV partitionv and casing, a reflector disposed within said casing, a plurality of supports secured to said reflector, and a heating coil carrledby said supports. Y

In testimony whereof, I hereunto affix my signature.
