IBEBB, OF CANTON, OHIO, ASSIGNOR TO THE CANTON STAMPING & ENAMEL- ING COMPANY, OF CANTON, OHIO, A CORPORATION OF OHIO V v BURNING RACK Original No. 1,738,030, dated December 3, 1929, Serial No. 316,86, filed November 2, 1923.

My invention relates to burning racks for supporting enamelware from a conveyor which transports the racks and enamelware carried thereon into and out of a kiln.

More particularly the conveyor may be a continuous conveyor, and the kiln may be a continuous or tunnel kiln.

In order that the total number of enamelware pieces burned per hour'in any particular kiln be a maximum, particularly in; a tunnel kiln, it is desirable that a burning rack structure and arrangement be provided which.

These and ancillary objects are attained in the present invention, a preferred embodiment of which is hereinafter set forth in detail, and is illustrated in the accompanying drawings forming part hereof, in which Figure 1 is a fragmentary elevation view illustrating the improved burning rack; and

Fig. 2, a detached fragmentary perspective View more clearly illustrating the self-connecting members of the rack.

Similar numerals refer to similar parts throughout the drawings. I

The conveyor indicated generally at 10 may be a continuous conveyor whichcontinuously passes into and out of a continuous or I tunnel kiln.

Application for that each of the outer and upwardly opening bends 1 1 may be self-connected with one of another set of interchangeable rack members, that is, the depending rack tray suspending frames 15. a

Each frame 15 is preferably rectangular in shape, andmay be formed of wire, and includes spaced side members 16 and 16, respectively, a bottom member 17, and a top member 18.

The side and bottom members are preferably straight, and the top member 18, has preferably formed in the central portion thereof, a stop yoke 19 opening downwardly and extending upwardly in use; and each yoke isadapted to be self-connected with one of the upwardly opening bends 14 of a W hook for suspending a frame 15, and the yoke when used in another position is adapted for stopping swaying of the rack structure made by the several rack members as will hereinafter be set forth.

The remaining set of interchangeable rack members are the rack trays 20, each of which preferably includes laterally spaced longitudinally extending angle side members 21 and 21, the ends of which are connected by end bars 22, thus forming a rectangular rack tray and a plurality of longitudinally spaced ware supporting pins 23 extend upwardly gil'om each of the tray side members 21 and Spaced downwardly opening tray suspending hooks 24 are secured to each end bar 22.

Similarly, upwardly opening suspending frame supporting hooks 25 are secured to each end bar 22.

Each suspending hook 524: is preferably formed integral with a supporting hook 25 bybending the opposite ends of a verticall extending strip 26, and each strip 26 is preerably secured at its central portion upon the outer face of one of-the end bars 22.

.Each pair of suspending hooks 24 is adapted for self-connection with the bottom mem bar-17 of one of the suspending frames 15,

"for suspending the particular tray 20 from one pair of suspending frames 15-.

Each pair of supporting hooks 25 is adapted for self-connection with the outer ends of a top member 18 of another suspending frame 15, for suspending from the particu lar tray 20, another pair of suspending frames 15, so that another tray 20 may be suspended below the next upper tray 20.

When the frames 15 are used for suspendinga tray below another tray,each u' ward- 1y extending stop yoke 19 is positione' oppoself-connectingrack members, a tiered rack having any number of tiers of trays 20 may he suspended between each pair of .o posite upwardly opening bends 14 on the hooks '12 carried by the conveyor 10.

The enamelware indicated generally at 27 is supported in the usual manneron the pins 23, andtheimproved racks and enamelware supported thereon are preferably continuously transported through the kiln, not shown, by the "continuous conveyor 10.

By-the foregoing'burning rack constructio'n'includin'g a conveyor, 'oneor more interf mediate or suspending members carried by thejconveyor, and one or more rack members carried by the intermediate members, together with the stop meanslimiting relative movement between the rack members and intermediate members, the practical operation of a continuous tunnel kiln for enamelware manufacture is made possible, with closely spaced racks, because by preventing the rack members from swaying endwise or longitudinally with respect to the conveyor, the racks are prevented from striking each other, and

' the ware supported by the rack members "I claim:

the lik -mcludlng a plurallty of interchange- 1 and, t ke n u g a yo f is prevented from slipping off the racks when turning corners, when the speed of the Conveyor is varied, or when the conveyor is started and stopped, it being'understood that any unburned warethat slips on the supporting pins, is rendered unfit for burning.
