. CONTINUOUS TU BHAOE.

lppucatioa med September mag/'comma own that we, TuADDEUB F. Baimr -.1 Baak' andfFanir QT. Corn, citizens of vthe United at Alliance, in theY .':Ste'fs .beth resida a county of Stark ang State of Ohio, have invented a new anduseful Continuous Furrutceof gwhich the following is a specification.;

This .invention' relates to continuous furmovement ofithe furnace-"being sutliciently slow t9 the 'articleeupon the platformv fu'p to'jthe temperature.

'llieabove andy other objects' may be at: -attained byiprovidn'g acircular platform, a.

railbeing provided around each side of said platform, the,furnaoe.being mounted upon said rails and provided with'suitable motive power to propel the same 'slowly around the platform.

Although the furnace is illustrated in the drawings as arranged to travel upon a circular platform, it will be understood that the invention may be carried out withut 9,1921. seria; no. 499,800.'

Fig. 3, a section upon the line` 3 3, Fig. 2.u n aalightly smaller scale; ig. 4, 'a view similar to Fig. 1, showing a modi ed form of-the furnace;

gig. 5, av section on the line 5'- '5, Fig. 6; an Y Fig. 6, a section on the line 6-6, Fig. 5.

Similar' numerals ofreference indicate corresponding p arts throughout the several res of: the drawings.

.The circularplatform which is indicated at 1, is of suitable height to serve as the hearth of the furnace, and may be covered fire brick or the like, as shown at 2. A circular rail 3 is provided u n `each side of the platform, upon which t e furnace is mounted to travel 1n a circular path'` around tform and the movable furnace for the purpose of preventing heat from escaping from the furnace.

The `furrfiaee. illustrated is of the electrically heated type, a d is provided upon each side with a resis 'r trough, these resistor troughs being preferably curved to conformv with the side walls Aof the furnace, being designated by the numerals 11 and 12, each trough being filled with a resistance body, consisting of al -carbonaceoua material in granular form,',.auch as crushed coke,

charcoal `or the like-,f-.which is designated at' 13 in the drawing8.- Embedded in the resistance material, preferably neareach end of each trough, as best shown Vin Fig. 3, is an electrode 14, which extends through the adjacent wall of the furnace.` A pair of circular conductor rails 15 16, concentric with the circular platfo 1,

lare located adjacent to the platform, prefer-- A collector arm 18 ispivotally 'connected at one end to the'frame of the furnace, the collector shoe 19 thereof being held by grav- .ity 1n` contact withV the conductor rail 15, a

similar collector arm 20 being provided with a.v shoe 21` "which engages the conductorbe of thesame construction as shown and y rail 16. v

The collector arm 18 is connected by.

means ofthe conductor wire 22 'with the. .electrodes atone end of each trough 11.and

12 and the collector arm 20 is connected by means of a similar conductor wire 23 with the electrodesV at` the other end of each trough, thus roviding a circuit through each of the resistor troughs.

.A motor 24 is carried by the frame 7 l preferably being supported above the furnace as shown in the drawings,'a pinion 25 Y `being mounted upon the motor shaft 26 and meshing with a gear 27' mounted .upon the shaft 28, which is carried in suitable bearings 29 suppoltel from vthe frame. l

A bevel pinion -30 is fixed upon each end of the'shaft 28 and meshes with aV bevel gear 31 mounted upon the upper: end of the adjacent, vertical shaft 32, said vertical shafts being journaled in `bearings 33 supported `upon the frame 7..' A bevel pinion A34 is A `fixed upon the lower end of cach of said vertical shafts and meshes with a bevel gear 35 mounted upon the'axle 36 of the adjacent wheel 8,

"The moto;` 24 is connected to the electric circuit by means of the conductor wires 38 and 39 whieharc connected to arms 18* and 20l respecti" The collector arms and20 are pro-V vided with suitab collector shoes which engage the ci/ular conductor rails 15' and 16 respectively, these conductorrails being conn L to any suitable source of electric energy as by the wires 17, Y l

Electric energy is thus furnished to th motor which operates the traction wheels of the furnace and to the resistor elements which heat the furnace, from the sources of electric energy through the conductor rails 15--16 and IFF-16", the resistor troughs and motor being in circuit with said conductor rails at any point around the circular platform.

'. In operating the furnace, the. current is caused to flow through the conductor rails 15-16 and IBL-46", and through the collector shoes and arms the current is carried to the resistor troughs of the furmue,.heat ing the interior of the furnace to the desired temperature, while at the same time the motor 24 is operated and through the gearing above described, the traction wheels 8 are -column above said shoulder.

rotated,'moving the furnace slowly around theY circular platform 1 upon the rails 3. The articles to be lim-ted are placed upon, the platform in advance of the moving fur nace and removed therefrom after the fur described in Figs. 1 to 3 inclusive.

In this form of the invention, a vertical column 40 is mounted concentric to the circular platform l and is provided midway with an annular flange orV shoulder 4l, ifa

sleeve 42 being rotatably mounted upon the provided with a pair of diamctrically opposite trunnions 43 to which are pivotally connected the inner extremities of the angle irons 44 which extend to the roof of the movable furnace.

A series of spaced rings 45, 46, 47 and 48 are located around the sleeve 42, being This sleeve is spaced therefrom by. the insulated bars 49.

lVires 50 and 51 are connected to the electrodes and 53 respectively of the resistor troughs, the wire 50 being connected to the ring 45, and the wire 51 being connected to the ring 48.

The wires 54 and 55 are connected to the rings 4G and '4T respectively and lead to the motor 24". It. will be noted that all of the wires 50, 51,'54 and 55 extend upwardly between the sleeve 42 and the rings 45, 46,

.47 and 48, beingconnccted to the inner surfaces of 'said' rings, thus leaving the outer e'll'ects'mzfgccs of ther-ings .free of any obstruction.

A bracket 56 is supported upon the colmn above the sleeve Al2 and the insulated bar 57 depends from said bracket parallel to he sleeve and carries the projections 58, 59, 60 anlfl 6l, which engage the rings 45, 46, 47 and 4S respectively.

The shoes 58 and 61 are connected by means of the wires (32 with a suitable source or electric energy for supplying the resistor troughs and the shoes 59 and G0 are conncctc'l b v means of the wires 63 with a suitable source of electric energy for supplying the motor. i

As the movable furnace is thus carried around the circular platform, the sleeve 42 l will be rotated upon the column 40 by means of the angle bars 44, the rings 45, 46, 47 and 48 being;r held in contact with the' shoes 58, 59, 60 and 6l respectively, the
