effimera TILE- Specification of Letters Pate-nt.
Application led June 10, 1920. Serial` No. 388,018. i v
To all whom t may concern:
Be it known that I, HLVER R. STRAIGHT, a citizen of the United States, and resident of Adel, in the county of Dallas and State of Iowa, have invented a certain new and useful Building Tile, of which the vfollowing is a specification. Y v
Hollow building tile, as ordinarily constructed, havel many advantages in wall building, over solid bricks, but have the disthe joints as well as it is retainedl vbetween the abutting ends of solid bricks.
Mv object is to provide a hollow 'buildingr j grooves arranged diagonally, then -no matter tile of simple, durable and inexpensive' construction, and so constructed and arranged as to provide an efficient and durable re joints tainer for the mortar between the thereof when constructed in a wall.`
My vinvention consists in the construction of the hollow tile building block, whereby the objects contemplatedare attained, as
hereinafter more fully set forth, pointed out in my claims, and illustrated in Vthe accompanying drawings, in which: 1 r
Figure lshows a perspective viewy ofahollow tile'building block embodying my invenf' tion.r A v v Figure 2 shows an end viewof one end` thereof.
Figure 3 shows an end view of the otherl end, to. illustrate the relative arrangement of the mortar retaining grooves; and
Figure 4 shows a perspective View illus= trating parts of two adjacentbuilding blocks with a mortar oint between them, illustrating the manner in whichthe mortar joint is retained in position.
Referring to the accompanying drawings, I have used the reference numeral l0 to indicategenerally the body of thehollow tile building block, which yis of ordinary construction.
At one end-thereof I have formed a series of substantially parallel V-shaped grooves ll, which grooves are preferably arranged atV an angle of about forty-five degrees relative to the front face of the building block. On the other end of the same block is a similar series of V-shaped grooves 12, which are like the grooves l1 in construction and arrangement, except that they are preferably eX- tended at a somewhat different angle relativev to the front face of the building block.
The numeral 13 indicates a mortar joint extending between two adjacent .building clay and before the clay is baked or hard-k j i cned, so-thatthere is practically no additional expense in the manufactureV caused by the forming of the V-shaped grooves.
sometimes laid with theirnarrowv face outer- .most in the wall, and sometimes with the ci? wide face.k vHence, by having the V-shaped which way the building blocks are laid in a wall, themortar between the joints willk be received into the Vv-shaped groovesand'be prevented or locked thereby against outward movement. Furthermore, 4 by having, the
grooves on one end arranged at ,different angles than the grooves on the Vother end,then
when two grooved building blocks are placed together the lines of the grooves willjcross, l to a greater or less extent, and will thereby, lock each v movement inl any direction. j
I am awarethat,heretoforehollow building blockshave been provided lwith grooves Y 85 l.
in ltheir ends, parallel toone or the other of; the faces of thezbuilding block, and'in such instances these grooves serve, to a certain 'eX- tent, in preventing movement of the mortar in one direction only, but they do not in any way prevent movement ofthe mortar in a direction parallel with the grooves, and hence when the grooves on the two adjacent ends of two building blocks are arranged parallel they do not serve to prevent movement of the mortar in the direction of the grooves.
Howeven by forming the building blocks so that the grooves will always cross or be out of parallel, the grooves will then form 'a l positive lock against movement of the mortar, no matter how the blocks are laid in the 10o wall. Y I claim as my invention: I l. An improved hollowtile building block formed with `grooves in the faces of itsj ends,
thek grooves in the facesofone end being arf- 105l ranged inv an angular 1 relation with the v,
grooves of the opposite end, and in'such'a manner that when twok of the said building blocks are laid end to end in a wall the grooves in the face ofone block will not be` 110 In' aL building wallvthehollow blocks are l V704'l fr particle. of vthe --mortar against` Y parallel with the vgrooves in the faces of an those atone end being arranged inangles diadjacent V-block, so that mortar placedAbe-mvergent from the plane of the face of the e "tween the ends of ythe blocks may loeY held block, and those at the other end being ar- 10 lagainst movement longitudinally with 'the ranged at angles divergent from those on the Y V5 grooves in the adjacent faces. first mentioned end, for the purposes stated.l
