THOMAS ALLSOP, OF PHILADELPHIA,
PENNSYLVANIA, ASSIGNOR TO THE PHILA- DELPHIA DRYING MACHINERY COMPANY, OF GERMAN TOWN, PENNSYLVANIA, A
CORPORATION OF PENNSYLVANIA.
DEVICE FOR SUPPORTING CHINAWARE OR THE LIKE DURING THE PROCESS OF MANUFACTURE Application filed January 23, 1920, Serial No. 353,437. Renewed April 8, 1925.
To all whom it may concern:
Be it known that I, THOMAS ALLsoP, a citizen of the United States, residing in Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Devices for Supporting Chinaware or the like During the Process of Manufacture, whereof the following is a specification, reference be 1 ing had to the accompanying drawings.
' The invention relates to trays for supporting articles such as china, porcelain, pottery, etc., during certain stages of their manufacture, more especially during drying after the application of the glazing solution,at which time it is essential that they be supported in positions of best advantage for the draining of any excess coating. Be cause of differences of form, different articles dry best in different positions: for example, large plates or other similar comparatively shallow articles dry more readily when in a vertical position, While the drying of cups,
saucers, bowls and so forth is expedited when they are laid fiat.
the various requirements above noted, I have devised a tray which is capable of inversion upon suitable supports, and, when turned to one position, capable of sustaining its charges flat or horizontally, and when in the other, of sustaining them vertically.
The invention is also directed to devices for positively maintaining the tray against displacement upon its supports when in either 'of its positions.
The invention is further directed to means for keeping the tray in place or pivoting it during turning, for guiding itto seat properly on its supports, and for facilitating engagement of the means for preventing dis placement of the tray, and which are further functional as guides in facilitating the interengagement of the devices above noted, after reversal.
The invention is also in part directed to a grilled tray of such form as to permit the ready flow of the drying medium therethrough, and which, upon removal from its supports, may be easily cleansed of any adhering dried particles of the glazing solution.
The invention further comprehends certain novel details of construction and ar In order to meet rangement which will be better understood from the detailed description which follows.
I11 the drawings, Fig. plan view, showing a pair of conveyor sprocket chains between which is suspended a tray structure conveniently embodying my invention.
Fig. II, is an elevation of one end of the tray, showing to better advantage the mans ner of its suspension from the adjacent conveyor chain.
Fig. III, shows a cross section of the structure, taken as indicated by the line III-III in Figs. I and II; and
Fig.'IV, is a sectional elevation of the tray, taken as indicated by the line IV-IV, in Fig. I. v
The organization herein represented comprises a pair of conveyor chains 1, 1, having interposed in them at intervals, co-ordinated special links 2, 2, which serve as convenient means of support for the suspension of trays of my improved construction, one of such trays being indicated by the numeral 3, in the drawings. These trays are hung from the chains 1, 1, by means of brackets 5, 5, between which they are spanned and by which they are carried. These supporting brackets 5, 5- are freely fulcrumed at their tops about integral, inwardly projecting pivot lugs 6, 6 on the special chain links 2, 2, and are retained on= said lugs by washers 7, 7 and cotter. pins 8, 8. The brackets 5, 5, are provided with tray supporting means in the form of ledges 9, 9, which are pierced adjacent their ends with apertures 10, 10, preferably of quadrangular outline. These apertures are adapted for co-operation with either one or the other of two pairs of correspondingly shaped studs 11, projecting from the upper and lower faces of U shaped or channel fittings 12, 12 that embrace the side edges of the tray in the manner clearly shown in Fig. II. As will be seen from Fig. I, the fittings 12, 12, arecentrally located along the sides of the tray and are secured by bolts 13, 13. By this arrangement of correlative engagement means (such as 9 andll) on tray and supports, the tray is positively held against substantial movement or displacement upon the mounting brackets or supports 5 in either of its positions through the instrunientality of the I, is a fragmentary to the suspension brackets, the fittings 12, 12,
are formed with integral trunnions 15, 15, which project into vertical slots 16, 16, in the brackets. Thus it will be seen that as the tray is turned from one position to another, the trunnions 15, 15, cooperate with the up and down guides at 16, 16 to keep the tray in place, and serve as fulcrum pivots,. and, by preserving the alignment of the tray after reversal, facilitate the proper seating of the tray on the supports 5 and the engagement of the studs 11, 11, with the co-operating apertures 10, 10, in the support ing ledges 9, 9. If desired, however, the tray ma be bodily removed-for cleaning by tilting the same to a suflicient angle to clear the chains and their appendages.
The tray 3 itself is a grilled structure comprising a series of spaced bars 20 united by marginal strips" 21, 21 extending across the bars above and beneath,wi th interstices between the strips 21, 21 corresponding to the s 'acing of the bars 20. At one side (as siiown, the lower) of the tray, the bars 20, 20 are all preferably supplementedor provided with cleats 22, of a triangular cross section, the ridges thus formed being capable of sustaining, with minimum contact area, articles laid fiat or in horizontal posi-' tion. Upon its other (upper) side, the tray bars are provided or supplemented with a lesser number of similar cleats, -in the present instance, only two, symmetrically arranged as shown. By a series of upstanding spacin pins 25 in each, the cleats 23 are enabled to support shallower articles, such as plates, saucers, etc., in vertical ,ositions as illustrated in Fig. 11. The grllled 1 construction of the tr y (with the intersticed formation. of its si e edges) permits the ready circulation of the drying medium when the tray is employed, for example, in pottery or china dryers, and thereby facilitatesthe ready diffusion of the drying medium about the supported charges, as a result of which, more uniform drying'is accomplished. To facilitate circulation, the
lthou h I have shown the tray or shelf 3 as emp oyed in a chain type of conveyor,- "it will be readily understood from the foredurin 5. 5 comprising a pair of vertically slotted going description that the same may, with similar advantages, be used in conveyor trucks such as are ordinarily employed in connection with tunnel dr 'ers.
Having thus describe my invention, I claim:
