This invention relates to tile setters and a principal object of the invention is to provide a tile setter of generally improved form andfunctional properties.

The invention residesalso in certain novel structural details hereinafter described and illustrated in the attached drawings wherein:

Fig. 1 is a side elevational View of a tile setter made in accordance with theinvention;

Fig.2 is an end elevational view of the tile setter;

Fig. 3 is a plan view of the tile setter;

Fig. 4 is a sectional view of the tile setter on the line 44, Fig 1;

Fig. is a fragmentary view in perspective of one end of a plate member;

"Fig. 6 is an enlarged fragmentary end elevational view showing details of structure, and 7 Figs. 7 and 8 are respectively end and side elevational views showing two of the tile setters in normal stacked relation. 7

With reference to the drawings, a tile setter made in accordance with the invention comprises two end members, 1 and 2 respectively, and a vertical series of horizontal plates 3 supported by and between said members. Each of the plates has a tongue, 4 and 5 respectively.

. at the opposite ends which fit into slotted openings 6 in the end members 1 and 2, and preferably, the tongues are cemented in the openings 6 so as to form a strong and rigid connection between the end members and the plates and to afford a substantially rigid, strong the setter structure of the general form illustrated.

With further reference to the end members 1. and 2, these are identical in character so that a detailed description of one will suflice. As shown in Fig. 2, the opposite side edges 7 and 8 of these members are recessed as indicated at 9, these recesses extending over the major height of the member so that in face profile, the member exhibits the form of an I. The upper surface 11 of the member is provided with a pair of upstanding elongated bosses 12 and 13 which lie respectively at the opposite ends of said surface and which extend from the end edges inwardly toward and terminate just short of the transverse center line of said surface. As shown in Fig. 3,.the flange 12 lies at the opposite longitudinal side edge of the surface 11 from the flange 13. The inner end of each of these flanges, i; e. the end which adjoins the said transverse center line, is slightly recessed as indicated at 14 and 15 respectively; and the inner end edges 16 and 17, and the inner longitudinal side edges 18 and 19 of the flanges are bevelled as indicated. Also, the inner terminal edges of the recesses 14 and 15 are bevelled as indicated at 21 and 22. As also shown in Fig. 3, thetransverse width of each'of the flanges 12 and 13 is somewhat less than one-half the overall transverse width of the end surface 11.

The bottom surface 23 of the end member is provided with flanges 24 and 25 which correspond in form, dimension, and relative location to the flanges 12 and 13 of 2 the upper surface described'above, with the exception that the positions of the flanges 24 and 25 are reversed with respect to the longitudinal side edges of the surface 23, so that the flange 24 adjoins the same face of the end member as the flangelZ at the top of the end member and the flanges '25 and 13 adjoin the opposite side face. In other words, the flanges'of the top and bottom surfaces which lie on the same side of a longitudinal median plane normal to the faces of the end member, will respectively adjoin the opposite longitudinal side edges of the two surfaces, so that if two end members in normal vertical position are superimposed in aligned relation one upon the other the flanges on the upper end surface of the lower member will in effect mesh with the flanges on the-lower end surface of the upper member so as to preelude relative displacement of the members in the horizontal directions. Since the end members areidentic al,

, it follows that the same relative positioning of the flanges prevails at the opposite end of the tile setter unit, so that if any two units'are mounted one upon another, as shown in Figs. 7 and 8, arid regardless of which end overlies another, the flanges at both ends will enter the aforesaid intermeshed relation to afford a stable stack in which the flanges function to preclude relative lateral displacement of the units. r 1

The form of the plates 3. is best illustrated in Figs. 3 to 6 inclusive. Each of the plates is slightly less in overall width than the minimum width of the end members so that when the tongues 4 of the plates are inserted in the apertures 6, the side edges of the plates will be slightly inset from the proximate edges of the end members. The tongues 4 of the plates are preferably only slightly less in width and thickness than the length and height of the slotted openings 6 so that the tongues fit freely within the slots, and the effective length of the tongues is such that in assembly with the end members, the outer end surfaces of the tongues are approximately flush with but do not project beyond the outer faces of the end members. As shown in Fig. 5, each of the tongues has shallow recesses 31, 32, 33 and 34 in the upper and lower surfaces, these recesses extending inwardly from the terminal end surface of the tongue and being relatively shallow. The

The corners 35 of the tongues 4 are rounded and each of these rounded corners terminates at the side edge of the tongue in a shoulder 36 so that when the tongue is inserted in an opening 6 in the end member a clearance space will be provided between the rounded corner of the tongue and the confronting rounded corner surface of the recess; this space is clearly indicated in Fig. 6 by the reference numeral 37. It isevident from the foregoing description that the recesses 31, 32, 33 and 34 and the recesses 37 provide substantial clearance spaces 'between the confronting surfaces of the tongue and the apertures 6, over and above the normal clearances shown in Fig. 6 and form cement receiving pockets by means of which the tongues and their plates may be rigidly cementitiously bonded in and to the end members. It will be noted further that the end surfaces of the plates between the longitudinal side edges of the plate and the corresponding edges of the tongues are recessed so that the end surfaces of the plates abut the inner faces of the end members only in the limited areas 38 and 39 which adjointhe outer side edges of the plates. This insures a solid and entirely stable seating of the ends of the plates against the inner faces of the end members and entirely relieves the tongue-and-socket joint of tortional strains that might arise from an unstable interseating of the end members and plate ends.

The faces of the plates are grooved 'asillustrated in Figs. 3 and 4, these grooves, 41, in the present instance and also the intervening ridges 42; having rounded crosssectional contours so as to avoid objectionable sharp inner corners and lines of potential fracture and to afiord minimum contact area between the plates and tiles resting upon the upper surfaces thereof. 7 a

The aforedescribed construction is well adapted to production of the tile setter from conventional refractory materials, and afiords a unit of highly desirable structural and functional characteristics. The units may be mounted in stable and closely set stacks upon the kiln cars with assurance of free and uniform'access of the heated gases to the individual tiles. The fact that the unit comprises components of only two diflerent and relatively simple forms and the ease with which the parts may be assembled insures relative economy of manufacture.

I claim: 7

1. A tile setter unit comprising a pair of upright end members and a plurality of tile-supporting plates supported on and between said members in vertically spaced series, said unit being adapted for assembly in vertically 4 stacked relation with other like units with the end members of each unit aligned with and seating on the end members of the adjoining lower unit, said end members having flat body portions of I-form face profile and having a vertical series of horizontal slotted openings, and tongues of lesser width than and projecting from the ends of said plates into said openings and cemented in the latter to secure the plates to the end members, the confronting surfaces of the tongues and openings being relatively formed to provide cement retaining voids between said surfaces, and the end surfaces of the plates at the sides of the tongues being recessed so as to confine the contact of said surfaces with the inner faces of the end members to limited areas at the outer ends of said surfaces.

2. A tile setter according to claim 1 wherein the voids are formed by recesses in the tongue surfaces.
