ANNEALING-TEAY.

Specification of "Letters Patent.

To all coho m, it'may concern:

Be it known that l, CORNELIUS 5. NOLAN,

a citizen of the United States, and a resi- 7 dent of Toledo, in the countyof Lucas and State of Qhlo, have invented a certain new and useful Annealing-Tray; andl do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to the manufacture of glass articles and particularly to means for holding or carrying such articles when placed in annealing ovens but is not restricted to such use as it may be used in any connection for which it may be adapted or appropriate.

The object of my invention is the pro vision'of improved means of this character, which will enable a greater number of arti- Zi oles to be placed in an annealing arch or oven at one time than has heretofore been possible, thus rendering a material saving in the fuel consumption for the output of a plant, and which also enables a direct and uniform subjection of the articles to the oven heat, whereby to enhance the efficiency and practicability of such means.

Further objects and advantages of the invention will be apparent from the following detailed description thereof.

The invention is fully described in the following specification, andwhile, in 'its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,--

Figure l is a perspective view of a double-story article-supporting tray embodying my invention. Fig. 2 is a front elevation thereof with the upper tray in longitudinal section and a portion of the lower tray broken away, and Fig. 3 is an end elevation of the lower tray. 1

Referring to the drawings, A designates the lower tray of the apparatus upon which may be mounted in vertically spaced relation any desired number of upper trays B, the number of such trays depending upon the height of the roof of an annealing arch a plurality or oven above the tray supporting lodges thereof.

The lower tray A, which is preferably of rectangular form, is shown as being of double angle-iron construction with the horizontal flanges of the angle-irons restin ohe upon the other and projecting inwar relative to the frame to provide an inner marginal supporting ledge 1 upon which the ends of laterally spaced cross-bars or slats 2 rest, and are secured by rivets or in any other suit-able manner, said cross-bars providing a grated form of bottom for the tray. T e forming of the tray bottom in this manner enables the heat within the oven to pass vertically through a tray, thus per mitting a more eilicient and uniform heat; ing of the artioles'resting thereon than would otherwise be the case. p j

Each end of the tray A is provided with a channel-bar strip 3, which is secured to the inner side of the lower one of the end angle-iron bars of the frame lengthwise thereof with its channel opening downward.

Mounted within-\ the opposite end portionswithdrawal of the same '5 and at the oppositeside thereof with complemental upwardly projecting L-shaped hooks 6 to facilitate a couplin together of 7 of pans, one in a Vance of the other, to enable them to be pilshed into or withdrawn from an oven in train form, as is customarily done.

The upper tray B, which is intended to be of substantially the same shape and size as the, lower tray A, is preferably ofsingle angle-iron construction, flange 7 thereof projecting inwardly at the lower edge is preferably formed of spaced slats on bars 8, which have their ends resting onand secured to the flanges 7 at the respective sides of the tray, as in the case of the lower tray. Supporting legs 9 are secured to the tray B at the corners thereof and preferably rest loosely upon the lower tor subja'cent trp. within the corner portions of the upstan of the frame. The tray bottoms rnrnls Parana enrich. i

facilitate an insertion of 85. The lower pan of a sef'is with the horizontal ing flange lhereoflo permita separation of:

the several trays or a building up of the n mber of superimposed trays employed without any increase in the fuel consumption thereof; thus eifecting a very material saving in the manufacturing expense of glass articles; and also that a tray constructed along the lines of those described is not only strong and durable, but permits of a more even and efficient acting of the oven heat upon the articles carried by the trays than is possible with theforms of trays commonly employed. v 1' I I wish it-understood that my invention is notjlimited to any specific construction,

form or arrangement of parts except in so far as such limitations are specified in the ,claim.

\ Having thus. ,,';described my invention, what I claim as new, and desire to secure by Letters Patent, is

7 An article of the class described, c0mprising a frame of double angle-iron construction with the horizontal flanges of the superposed angle-irons resting one upon another and projecting inward relative to the frame, spaced bars connecting opposite sides of the frame with their ends secured to said flange, a downward opening channel bar extending from front-to rear of the frame at each end thereof within the lower angle bar, and rollers carried by said channel bar.

In testimony whereof, I have hereunto A signed my name to this specification in the presence of two subscribing witnesses.
