Dec. 3, 1929. BEBE BURNING RACK ATTACHMENT Filed Nov. 28, 1928 attowuzq Patented Dec. 3, 1929 UNITED STATES PATENT OFFICE HARRY T. BEnB, or CANTON, OHIO, ASSIGNOR TO THE CANTQN STAMIING & ENAIvIEL- me COMPANY, or CANTON, OHIO, A conrona'rroiv or OHIO BURNING-RACK ATTACHMENT Application filed November 28, 1928. Serial No. 322,453.

My invention relates to attachments for burning racks for supporting enamelware from a conveyor which transports the racks and the enamelware supported 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.

The attachments of the Jresent invention may be used with many itferent types of burning racks, but areparticularly adapted for use with the improved burning rack set forth in my prior application for patent filed November 2, 1928, Serial No. 316,686.

In the use of burning racks, it is necessary to support various different shaped articles thereon, such as pans, cups, spoons, and the like in a suitable manner for being properly burned when passing through the kiln; and the objects of the present improvements include the provision of a plurality of different attachments each adapted for supporting one or more pieces of enamelware to be burned,

and each provided with engaging means for removably supporting the attachment on the burning rack and for maintaining the attachment and supported ware in the desired position during the movement of the rack through the kiln.

These and ancillary objects are attained in the present invention, preferred embodiments of which are hereinafter set forth in detail, and are illustrated in the accompanying drawing forming part hereof, in which Figure 1 is a fragmentary perspective view illustrating a burning rack with several em bodiments of the improved attachments hereof supported thereon, and some of the attachments are illustrated in use for supporting various pieces of enamelware;

Fig. 2, is a detached perspective view of one embodiment of the attachments; and

Fig. 3, is a detached perspective view of another embodiment.

Similar numerals refer to similar parts throughout the drawing.

The conveyor indicated generally at may be a continuous conveyor which continuously passes into and out of a continuous or tunnel kiln.

At spaced intervals, a plurality of rack supportingbars 11 may depend from the con veyor.

The burning rack illustrated, is the improved burning rack of my aforesaid prior application, and preferably includes a set of interchangeable W hooks 12, each adapter for being removably supported by its middle bond 13 in an aperture at the lower end of a supporting bar 11, so that each of the outer and upwardly opening bends 14 may be selfconnected with one of another set of interchangeable rack members, that is, the depend ing rack tray suspending frames 15.

Each frame 15 is preferably rectangular in shape, and may 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 yoke 19 opening downwardly and extending upwardly in use; and each yoke is adapted 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 preventingswaying of the rack structure made by the several sets of 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 from each of the tray side members 21 and 21.

Spaced sets of oppositely opening suspending and supporting hooks 24 are secured to each end bar 22.

Each set of suspending and supporting hooks 24 is preferably formed integral by bending the opposite ends of a vertically extending strip 25, and each strip 25 is preferably secured at its central portion upon the outer face of one of the end bars 22.

Each pair of spaced hooks 24 opening in the same direction is adapted for self-connection, either with the bottom member 17 of one of the suspending frames 15, for susv pending the particular tray 20 from one pair of suspending frames 15, or with the outer ends of a top member 18 of another suspending frame15, for. suspendingfrom the particular tray 20, another pair of suspending frames 15, so that another tray 20 may be suspended'below the next upper tray 20.

'' \Vhen the frames 15 are used for suspendng a tray below'a'nother tray, each upwardly extending yoke 19 is positioned opposite and adjacent an end bar 22, so that any longitudinal'swaying of thetiered rack structure thus made from the several sets of rack members, islimited by-abutment of one of the upwardly extending yokes 19 against the adj acentend bar 22. 1

, For forming all of the several sets of rack members it is preferable to use a heat re- 'sistmg metal.

For connecting the several parts of each tray, it is preferable to employ welding, although rivetingor other fastening means may be employed.

' The improvedattachments indicated generallyat ,30 ,'and 30, include, respectively, one or more ware supporting arms 31, 31",

. and 31, and engaging means, which may be,

respectively, notches 32 32 and 32, in one or more of the arms of each attachment.

.In the attachment 30*, a plurality of arms '3l rextend radially outwardly from a central junction 33, preferably in the form of a cross, and the outer end 34 of each arm, ex-

downwardly.

Theattachment 30 is particularly adapted for "supporting a pan, the flange 35 of which it is desired to decorate with a color different than the color of the body of the P'The attachment 3O includes a plurality of arms 3 1 extending radially outwardly and upwardly from a central junction 33, and the inner edges 38 of the arms'31 are preferably knife edges for supporting an inverted enamelware pan 39, as illustrated on the upper rack .tray in Fig. 1. l

The-notch 32* may be on the lower side of one .of the arms 31"-, for engaging the inwardly extending leg 40, of the angle side mem- 1 bers 21 0fone of the rack trays 20, when arrangedin the,position illustrated in the up per rack tray of Fig. 1 with the Ware supporting pins 23 extending upwardly.

The attachment 30 includes an arm 31 having a notch 32 in its lower side, and preferably provided with an upper knife edge 38, one end of the arm 31 at one side of the notch 32 having secured thereon, oppositely extending catch arms ll and 41, the outer ends of which are arranged to engage beneath the side members 21 and 21, respectively, of a rack tray 20, when the notch 32 is engaged over one of the end members thereof; so that the arm 31 may extend as a cantilever beyond the end of the rack tray, and a spoon 12, and/or a cup 13 may be supported thereon.

The foregoing attachments, each including ware supporting arms, and means engaging the rack tray, are very useful and substantially indispensible in facilitating the supporting of any desired piece of enamelware on the burning rack.

As illustrated it is preferred that the side members 21 and 21, have knife edges, for supporting enamelware directly thereon, when used in the position illustrated for the lower rack tray.

I claim:

1. An attachment for a burning rack and the like, including a plurality of ware sup- 9 portmgarms, and means for releasably engaging and supporting one of the arms on the rack.

2. An attachment for a burning rack and the like, including a plurality of Ware supporting arms, and means for releasably engaging the arms on the rack.

3. An attachment for a burning rack and the like, including a plurality of ware supporting arms, and notch means for releasably engaging and supporting one of the arms on the. rack.

4. An attachment for a burning rack and the like, including a plurality of ware supporting arms, and notch means for releasably engaging the arms on the rack.

In testimony that I claim the above, I have hereunto subscribed my name.

HARRY T. BEBB.
