PALLET FOR DRYINC4 BRICKS'.

j' SPECIFICATION forming part of Letters Patent No. 506,811, dated October 17, 1893.-

Application led September 8, 1888. Serial No. 2841852 (N0 111011810 To' all whom it may concern.-

Be it known that I, CYRUs CHAMBERS, J r., a citizen of the United States, residing at Wynnewood, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Pallets for Drying Bricks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of which- Figure 1,Sheet l, is a planview of one form of my pallet. Fig. 2 is a side elevation of two of'such pallets, the one resting upon the other, as in use. Fig. 3 is an end view of Fig. 2. Fig. 4 is a partial transverse section, enlarged, taken through the line a b, Fig. 2. Fig. 5 is a plan of aportion of one end of the pallet, showing the manner of connecting the ends of the frame, or handle, iron, and the supporting slat. Fig. 6 is a partial vertical section, enlarged, taken vthrough the line c d, Fig. 3. Figs. I", 2, 3", 4a, 5a and 6a, Sheet 2,

l, 2, &c., Sheet l, ot` another form of the invention.

The nature of this invention is a metallic frame, or pallet, adapted to support, duringV and after their transportation to the drying kilns or chambers (also within the kilns) bricks that have been molded by the so-called sti mud or plastic process, and are sufticiently rn to handle immediately after being molded.

Heretofore, as shown in my Letters Patent of the United States, Nos. 274,907 and 274,910, dated April 3, 1883, for improvements in kilns for drying bricks, &c., the raw bricks were arranged in hacks, upon their edges and upon each other; but this practice, I found, by experience, to be objectionable for va rions reasons; among others, in that the weight of the upper bricks tended to crush those below; in that there was not sulicient space to permit the free circulation of air around all sides of the several bricks; and in that their edges or faces were marred or defaced by the impression of the contiguous upper and lower bricks. My present improvement is designed to obviate these objections, and to produce a blk supporting pallet whereby the clay will be better dried, and a more perfect and uniform brick produced.

The invention consists, primarily, in a m'etallic pallet, composed of a brick-supporting slat, or slats, provided with ahollow frame, or handle, at each end thereof, whereby the pallet can be readily handled, and whereby a number of such pallets can be supported upon each other, without the bricks being brought together in contact, and thus a free circulation of the air assured.

The invention consists, secondly, in forming said frames, or handles, of a height and length exceeding thel width and length, respectively, of the brick to be dried, whereby the latter may be laid upon its side or edge transversely to the supporting slat, or slats, Without projecting beyond the edges of said frames or handles, and thus, when the pallets are piled one upon another, and close together sidewise, vertical and horizontal air spaces between the several courses of bricks, will be provided.

. rlhe invention consists, thirdly, in longitudinally bending or corrugating the edges ot the supporting slat, or slats, in order to stiften the latter, and in so forming the lower edges of the end frames, or handles, that they will conform to, or nearly to, the shape ofthe ends of said slat, or slats, and thus be bound firmly to, and be also prevented from shifting or twisting upon, the same.

The invention consists, fourthly, in providing the upper and lower edges of the pallet ends with projections and recesses, respectively, in line vertically with each other, whereby, upon the registering of the projections and recesses of the adjacent pallets, proper alignment of the pallets, in the piling thereof, will be assured, and lateral displacement of the same prevented.

. The invention consists, tthly, in forming the upper projections of said pallet directly in line vertically with the point of connection of the end frames, or handles, with the channeled or corrugated supporting slat, or slats, whereby the ends of the latter form the above described registering recesses.

The invention consists, sixthly, in forming each of said upper projections with a longi- ICO tudinal groove or depression, whereby, when the pallets are piled upon each other, the heads of the bolts or rivets connecting the slats and handles will enter the depressions in the projections of the adjacent pallets, thus securing endwise alignment of the latter, and preventing their displacement endwise.

The invention consists, seventhly, in providing the meeting ends of the bent handles or end frames, at tht point where they are bolted or riveted to the slat, or slats, with an lnterlocking tongue and groove, respectively, whereby said ends are kept in alignment and made firm and rigid without welding.

The invention consists, finally, in details of construction, which will be hereinafter described and duly claimed.

Referring to Sheet l of the annexed drawings, wherein one form of the invention is` illustrated, A represents the pallet, which is composed of a brick-supporting slat, d', provideclwithend frames or handles, b. The slat af consists of a comparatively long narrow piece of thin metal, say, one-eighth of an inch thick, whose lateral edges, d2, are bent down, as shown, whereby the same are rounded and the slat greatly stiffened and strengthened. The width of this slat is much less than the length of the bricks to be supported thereon, so that when abrick is set upon its edge,y cross wisezof the slat, the ends of said brick will project beyond each side of the metal, say, one-fourth the entire brick length. Thus, the ends, sidetop edge or face, and one-half of the bottom face. of the brick, will be exposed to the action of the heat and air withinthe kiln or chamber'inwhich-the pallet, with the brick balanced thereon, is contained.

rlhe end-frames,or handles, b, are made of half-oval iron, each frame consisting of a single piece of metal bent as shown in Fig. 3, thatis to-say,-so as to iit around the top and sides of the slat a', extending outward horizontally therefrom, as at b', up at right angles or vertically, as at b2, and horizontally over the top, as at b3, so as to form an open rectangular end frame, whose height and lengthexceedl the width and length, respectively, of the brick to be supported upon they pallet,

whereby, when such pallets are piled one upon another and close together sidewise, vertical and-horizontalv air-spaces between the severall coursesy of bricks, will be provided. These frames are secured to the ends of the slat a. by means of rivets, or bolts, a3, and in order to secure rigidness without thenecessity of welding themeeting ends of the half oval iron,I provide said ends, before bending, with.

a tongue, b4, an dgroove, b5, respectively, which iit into each other when the metal is bent, thus securing the two ends in perfect alignment, as seen in Fig. 5. This frame, or handle, being bent as above described, so as to conform to the upper surface of the pallet slat, cannot move sidewise nor twist when riveted or bolted to said slat. Hence, the palto 6a, both inclusive.

let, as a whole, is rendered very rigidy and substantial.

In order that the pallets will stand steadily upon the floor of the drying room or car, and upon one another, the lower edges, b', of the handles, b, are so formed as to slightly project below the turned edges of the slat, as clearly shown. In order, also, to insure the correct disposal of one pallet upon another,

Aand to guard against lateral displacement thereof, during the passage of the car carrying the same, I provide the upper edge of each of the handles or end frames, directly in line vertically with the slat, with a longitudinallygrooved projection, b", which is adapted to enter the concave or under side, d4, of the slat of the contiguous upper pallet. The longitudinal grooves, 57, in these projections, permit the heads of the bolts or rivets, a3, to enter therein, thus preventing endwise displacement of the pallets.

A pallet constructed as above described,is

- designed, more especially, to Jsupport bricks composed of stiff or strong clays, as those composed of weak or tender clays are apt to droop at each end over the narrow supporting slat, and, in some cases, to evenbreak in two and falldown upon the bricks below. In order, however, to provide for the support ofy such soft clay bricks, I construct the pallets as illustrated in` Sheet 2 of the drawings, that is, with two bottom slats, a a, each of which is i narrower than theslat of the. first described g construction, andl has its lateral edges, like- A wise turned down.

Theseslats are disposed at such distance apart as to allow the endsot" g the brick torest thereupon, and theendf rames, f or handles, ZJ, are bentto fit around'each slat, i and are securedV thereto, as-shown in: Figs. l@

It will be observed-by f reference to Figs. l, 3a and 4a, that the grooved projection, be, on the top of each handle is toward one side, and is adapted' to iit intobut one of the slats of the upper ad- :jacent pallet, and also that the projections are at opposite sides of the pallet. The obj ect 1in this, is economy in construction, andtoy avoid the making of another grooved projection above the point where the twoends' ofl the handle are united by thetongue, 54 and groove, b5. As each handl'evis-rifvetedfor'bolted to both slats, it is obvious that a firm and rigid structure is produced.

By means ofthe twin-slab pallet just described the drying of the under edge or face of the brick is greatly facilitated, and the described' defect incident to the single-Slat pallet, in supporting bricks composed of" weak clays, is entirely remedied. p

Having thus described my invention, I claim as new and wish to secure by Letters Patent- 1. A brick pallet' comprising two open or skeleton end frames ofa height andn length exceeding the widthv and length respectively of the brick to be supported upon the pallet,
