JAMES E. DOYLE, OF CLEVELAND, OHIO.

REFLECTING HEAT APPLLANCE.

Application led October 15', 1921, Serial No. 507,931.

To all whom it may concern.'

Be it known that I, JAMES E. DoYLE, a citizen of the United States, residing at Whittier Ave., Cleveland, in theA State of Ohio and Cuyahoga County, have invented a new and useful Improvement in Reflecting Heat Appliances, of' which the following is a specification, the principle of the A invention being herein explained and Vthe best mode in which I have contemplated applying that principle,

from other inventions.

This invention relates to a heater and the manner of adjustably mounting it upon a so as to distinguish it machine including a conveyor.

effective More particularly, the present invention is exemplified by a plurality of electrical heating units Jadapted when .energized to present incandescent or glowing elements in proximity to material moved by said'conveyor and which material it is desired to have pass through the'heated zone.

The drawings illustrate the practical application of my invention in various waysto 25. different types of printing presses on which freshly printed paper sheets are transferred and the ink of which it is desired to dry to prevent offset besides removin the static electricity in the sheet. It shou d be underv30 stood'that the use of the invention need not be restricted. to printing machines nor to machines on which the traveling sheets vare paper.

The objectnof my invention has been to Adesign what may be termed a reflecting heater and employing an electrical unit elliciently located with respect to a reflector purposed to concentrate the heat in a prescribed direction. Frequently, or gang of vreflecting heaters will be advantageous; but whether heater or a series of reflecting heaters are.

employed it is desirable to enable adjustment in diverse directions".

I am well acquainted with'the development of' this art, having already obtained several patents belonging ver, havingseveral pending applications; in consequence of which I have necessarily become familiar with the disclosures of a number of prior patents, including, Hergesheimer No'. 897,831, Daningburg No. 97 8,7 04, i

and Lane No. 991,860. Specifically, my present invention d1scloses means for adjusting one or more heata plurality' a single reflecting element observed from to it and more-.

ers in right angularly related directions with respect to a conveyor, means for 'adjusting one or any desired number of heaters crosswisek of the path of travel of a sheet drawn or carried by said conveyor, means for independently swingin any one or a plurality of heaters together a out an axis and means Aincluding a universally movable connection enabling each reflecting heater to be not only adjusted in any conceivable direction but held in any chosen position of rest. Various details of construction of the mount- 1ng of the electrical heating unit and of the reflector connection are believed togembrace patentable novelty. y

Adverting tothe six sheets of drawings Figure I may be considered as a plan section of a portion of a printing press employing a printing cylinder upon which printed sheets are conveyed and showing as a plan view the mounting of a gang of reflecting heaters on a tubular carrier so that "each heater may be universally adjusted with respect adjustment in three directions.

Figure XXV is a plan view showing how a batch of printed sheets, scattered on al table to dry, may be more quickly dried by the employment of a series of my radiate refleeting heaters.-

Traveling on 'a cylindrical conveyor 1 are freshly printed sheets 2. AStandards at opposite ends of a printing press include each a horizontal portion 3 and an upright portion 4, the latter having an edge fashioned with a channel 5. The two lportions 4 are each to carry a bracket 6 vertically adjustable therealong by means of bolt and nut combinations 7 The heads of the bolts are shown fitted lwithin the channels 5 so as to be incapable of dislodgment in a direction perpendicular to the portions 4. Inasmuch as nothing is claimedv for this common form l of adjustable connection by itself, the cursory description furnished should suHiCe.

The upper part of the two brackets 6 are each similarly. fashioned with undercut channels 8 for the reception ofthe heads of a pair of bolt and nut combinations 9 which enable hangers 10 fashioned with bearings in middle portions to. be adjusted horizontally along the channels 8. Extending be tween and projecting through the bearing the tube 11 may be turned or slid in an'axial direction and secured in any desired position by means of the set screws 12 which pass through t-he tops of the hangers 10. Extending along the major portion of that side of the tube 11 which is nearest the conveyor l, the tube 11 is slotted at 13 as most clearly appears in Figure III and the purpose of which will presently be explained. rEhe possibility should now be apparent of adjusting the tube 11 "in four distinctV directions namely, by turning it, by moving it axially or crosswise of the path of travel of the sheets 2 on the conveyor 1, by actuating it Y toward and away from the conveyor 1 when the hangers 10 are loosened and by shifting l it in an up and down direction when the brackets 6 are loosened.

rlhe mounting upon the tube 11 of each of the four reflecting heaters shown in Figure I being the same, only one need be described and accordingly the singular number will be employed. TA clamp 14 fits around the tube 11 and on its one side is slotted at 15. Near each end of the slot 15 the clamp 14 carries a pair-of bosses 16. Bolt and nut combinations 17 serve to draw the bosses 16 together to effect the clamping action whereby to fix the clamp in a predetermined position onthe tube 11. The loosening of the clamp 14 will obviously permit it either to be slid along or' swung aroundv the tube 11.

The clamp 14 is fashioned with a hollow lateral extension 18 internally threaded at 19 and adapted to afford communication through the slot 13. A hollow union 20 is screwed into the extension 18- and connects with a hollow well known goose-neck structure 21 which may be bent many direction, and carries at its extremity a conventional type of electrical socket 22 provided interiorly with a screw threaded lining 23. I attach to one side of the socket 22 'anzeyele't 24 with which a chain 25is connected,'the free en d of the chain being intendedto be attached in any desiredfmanner Lto an appropriately located fixture for the purpose of affording additional means for holding -the socket 22 in some predetermined position of adjustment.

complementarily threaded shell 26 is adapted for detachable electrical connection with the socket and includes an insulating extension 27 provided be ond the socket 22' swith an annular rim or ange 28 and in its end" with a pair of terminal sockets A29. Nothing being claimed for the manner in which electrical connection 4is effected up toughness and insurance against fractures either due to sudden temperature changes or vibration or both simultaneously. To date, I have most successfully employed a lava. The core 33 is fashioned with a plurality f and as shown with four equispaced bores 34 extending longitudinally from end to end, only two of the bores being occupied by electrical conductors 35 each projecting from the saine end as a `pair of flat terminals 36 adapted to be inserted in the sockets 29 and to be held in place therein with a yielding engagement cominon to the art. The cylindrical surface of the core 33 is fashioned with a helical groove 37 in which is wound an electrical heating element 38 having its ends detachably connected with the conductors 35. As designed, the coiled element 38 will attain a glowing heat or in other words will become incandescent when the heating unit is energized as will now be described.

A pair v of wires 39are connected `with the terminals in the socket 22 and passing upwardly through the goose-neck 21 and through the clamp 14 are then led through the tube 11 to emerge at one end thereof, after which they pass around therlower sides of a pair of sheaves 40 and thence to suitable switch controls 41y diagrammatically shown in Figure II. The wires 39 are held intension by counterweights 42 suspended from the sheaves 40, so that the slack in the wires 39 will be taken up when the clamp 14 is adjusted along theftube 11. The provision of the slot 13 in the tube 11 enables the bends in the wires 39 where they pass through the extension 18 of the clamp to :move along the slot 13 according to the adjustment movement which may be imparted to the clamp 14.

As .will now be readily understood, depending upon the charactenof the printing job and the arrangement of the printed sheets 2 on the conveyor 1, the plurality of reflecting heaters may be set in innumerable positions `of adjustment both with respect to the conveyor 1 and with respect to each other. Figure I hap-pens to illustrate four heatersl projected substantially horizontally from the tube 11 and at equal distances from each other for effective application of heat to what may be considered as either four freshly printedstrips 2 or a sheet of paper with fourfprinted areas in parallel strips. It might well be that starting with an equipment of four heaters, the extent of the printed area on a sheet or'sheets, carried upon the conveyor 1 and rection across the route of travel or in a line substantially parallelto one drawn between the strands 4, will be so restricted'as not to require the heat from say, one or both of the end heaters. In such eventY a ready control is afforded by means of a separate switch 41. v Depending also upon the bulk of the inked impression a plurality of heaters might be arranged to concentrate their heat radiation upon some particular area. of the passing sheet and this is clearly made possible by the manifold adjustments which I have provided.

The modification shown in Figures X to XV inclusive shows the mounting of one of my reflecting heaters upon a Kelley type of press 43 which is equipped with a delivery board 44 along one side of which a bracket 45. is mounted by means of fastening devices 46. The bracket 45 includes a horizontally extending slot 47 along which a clamp 48 with a middle bearing section 49 may be adjusted in a manner similar to that shown in Figures I and V. The clamp 48 is itself fashioned with apair of arcuate slots 50 registering with the slot 47 such that when the fastening devices 51 are loosened the clamp 51 may be moved either along the slot 47 or turned with Vthe limits afforded by the slots 50. A bent tube 52 is mounted for adjustment movement within the arched section 49 and is to be securedby means of a set screw 53. Lead wires 54 pass through a suitable opening 55 in the tube .52 thence measured in a di? through a goose-neck 56'and to a socket 57 n carrying a reflector 58, and a heating unit (not shown). An'adjustable chain length 59 connects the socket 57 with the rigid end ofthe goose-neck 56 to steady the heater against vibration. As is clearly shown by rthe alternative posit-ions of the heater shown in dotted lines in Figures XI and XII the radiation of heat may be directed as ma prove most effective to the ited upon the board 44.

The modification shown in Figure XVI shows the application of my invention to a Gordon or.job press 60, which includes last sheet deposvdelivery or deposit shelf 61, transferring pile of sheets on the delivery a portion 68 of the goose-neck connection delivery 76.

from which is to be suspended a one-piece porcelain 69 including an annular rim 70 about which the neck 71 of a4 reflector is to be similarly spun. An electrical heating unit is then to be directly screwed into Athe socket 69 after the manner in which the shell 27- appears detachably connected-with the socket 22 in Figure VI just above Figure XVII.'

Figure XVIIIv is a diagrammatic view showing the application of a plurality of my variously adjustable reflecting heaters to a inking press 72 including printing rolls .7 3, a cylinder 74, a delivery table 75 and a fly Heaters 77, 78 and '79 are shown mounted so as to radiate heat to the side of the cylinder to the top of the cylinder and to the delivery board respectively. It is to be understood that adjustments of the heaters 77- and 78 may be accomplished similar to that shown in dotted lines in the case of the heater 79.

The diagrammatic view portrayed in Figure'XIX shows a press 80 with inking rolls 81, cylinder table 82, delivery board 83 and an extension delivery 84 for actuating and conveying a sheet in a manner Well` known `to the art. Heaters 86, 87, 88 and 89 are mounted for manifold adjustment at the side ofthe cylinder` 82, above the latter, above the delivery tapes and above the delivery board respectively.

Figure XX shows the application ofa series of heaters embodying my invention-to a two-color press 90 comprising one set of inking rolls 91,`a cylinder 92,'a transfer cyl- 'inder 93, another set of inking rolls 94 and another cylinder 95 from which the paper sheet is conveyed by a fly delivery 96'to a table 97. A heater`98 is adjustably mounted to radiate its heat toward one side of the cylinder 92. A pair of heaters 99 and 100 are appropriately suspended above to radiate heat downwardly toward the transfer cylinder93 andthe printing cylinder 95 respectively. Another heater 101 is again shown mounted so as to be capable of reflecting heat downwardly to each sheet when deposited upon the table 97.

Figure XXI illustrates diagrammatically a rotary press equipped with a paper roll 102 Ato be printed between cylinders 103 and `104 and again between cylinders 105 and 2111 intended to draw the ruled lines upon a paper sheet to b e conveyed backwardly on a conveyor 112,thence to another conveyor 113 preparatory to delivery to a table 114. Heaters 115, 116, 117 and 118 are shown arranged to radiate heat, the first downwardly immediately after the ruling operation, the next laterally in opposition to the -sheet moving upon the conveyor 112 and the last two just prior to delivery of the sheet tothe table 114 and after the sheet has been deposited on each table. Y

In FigureXXIII appears a plan viewfof a folding machine including a feed table 119, oblique rollers 120 adapted to cause the traveling sheets to hug a lateral flange 121 so that all will bedelivered to a folder 122. A heater 4123 is adjustably mounted at 124 so thatin addition to the adjustment enabled by its goose-neck connection, it may be swung around an arc over any desired series of the rollers 120 and incidentally at varying distances from the flange 121.

`It may occasionally prove desirable to mount two adjustable heaters on opposite sides of a delivery board as is suggested in 129 to dry,'the drying operation to be hastened with a series of, in this instance three, reflecting heaters 130 which are to be understood as likewise adjustable in severaldiV .rections 1.
