BUILDING-BLOCK.

SPECIFICATION formingpart of Letters Patent No. 781,844, dated February 7, 1905.

Application filed April 30, 1904. Serial No. 205,738.

To all whom it may concern.-

Be it known thatLLoUIs F. FICCLURIG, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful lmprovements in Building Blocks, of which the following is a specification.

My invention relates to improvements in building-blocks and walls, my object being to provide blocks of cement or other suitable material of plain or ornamental design and having the appearance of natural stone.

A further object is to provide blocks for the formation of hollow walls possessing great durability and strength and capable of being builtmore cheaply than walls of solid stone, as the blocks are lighter and easier handled.

Other objects of the invention will hereina tier appear, and in order that it may be fully understood reference will now be made to the accompanying drawings, in whieh- Figure 1 represents a perspective view of a portion of a wall built of my improved blocks. Fig. 2 is a detail perspective view of a preferred form of block. Fig. 3 is a detail perspective view of a preferred form of cornerblock. Fig. t is a detail perspective view of a corner-block arranged alternately in the courses of the wall with the block shown in Fig. 3.

Fig. 1 of the drawings shows a section of wall built of

blocks

1, 2, 3, 4, 5, and 6. Block 1 comprises a body portion T. provided at its opposite ends with arms 8, extending at right angles thereto, corresponding in height therewith, and of but one-half the thickness of said body portion. The top and bottomedges ol the latter are provided with longitudinal grooves S and centrally-disposed transverse grooves 9. extending from the rear surface of the body portion to the rear side of grooves 8. 1O designates grooves of but one-half the width of grooves 8, arranged in the horizontal outer corners of arms 8 and communicating with the ends of grooves 8.

Blocks 3 and 4: are sections cut from block 1 while the latter is green in order to avoid the expense of providing special molds for said sections.

Corner-block 5 comprises a body portion 11 l of the same heightand width as the body portion of block 1, arm 12 extending at right angles from one end thereof, and a solid corner portion 13 at its opposite end provided at its inner corner with a recess 14. The top and bottom edges of said corner-block are provided with U-shaped grooves 15, the transverse portions of which extending along the horizontal corners of arms 12 are but one-half the width of the other portions of said grooves. Block 5 is also provided with centrally-disposed transverso grooves ll), extending from the rear surface of body portion 11 to the rear edge of the longitudinal portions l grooves 15.

Corner-block is substantially triangular in plan view and has two vertical faces 17, extending at right angles to each other and communicating with vertical end pm-tions lb of less width than the solid central portion l.) of said block. block 6 is provided at its top and bottom edges with right-angular grooves and inwardly extending transverse grooves 20, communicating with the terminals of grooves 20.

In constructing a wall with the above-dcscribed blocks corner-blocks 5 are laid in every second course with their longitudinal sides extending at right angles to each other, and corner-blocks 6 are laid in each alternate course in order to break joints, and thus add to the stability of the wall. Blocks 2 are then laid with their severed ends abutting against the short side of blocks in order to break joints with blocks 1, arranged in alternate courses with blocks 2 in this portion of the wall. The inner portion of the wall, which of course is erected at the same time as the outer portion just describeil, consists of blocks 1, 3, and -i, the severed end of which latter engages recess let, while the end of its arm 8 abuts against the inner surface of block 2 near the severed end of the latter, so its arm 8 will abut against the inner intermediate surface of block 1, and thus break joints between the inner and outer set of said blocks, as shown in Fig. l. 'hen the blocks are placed in this position, grooves 10 in the abutting arms 8 in the outer set of blocks 1 communicate with grooves 9 on the inner set, while grooves 10 on the latter communicate with grooves 9 on the outer set. The grooves of the blocks I between the outer and inner blocks; and 1 are filled with mortar, which serves as a bond l shaped anchors which engage the grooves in in securing the blocks together, and the inner and outer sections of the wall are further secured together by I-shaped anchors 21, the longitudinal portions of which are embedded in the mortar in

grooves

9, 10, and 15 of

blocks

1 and 5, respectively, while their transverse portions are embedded in the cement in grooves 8 of blocks 1 and grooves 15 and 20 of the corner-

blocks

5 and 6.

Having thus described my invention, wha 1 claim, and desire to secure by Letters Patent, is

1. A building-block comprising a body portion having communicating longitudinal and transverse grooves in its top and bottom edges, and vertical sides which are flush throughout their entire length, and arms extending at right angles from the ends of the body portion of one-half the thickness of the latter and provided with grooves communi cating with the ends of the longitudinal grooves.

2. A building-block comprising a body portion having longitudinal grooves in its top and bottom edges and transverse grooves communicating with the central portion of the longitudinal grooves, and arms extending at right angles from the ends of the body portion of one-half the thickness and the same height as the latter; said arms being provided at their horizontal outer corners with grooves communicating with the ends of the longitudinal grooves. substantially as shown and described.

3. A building-block comprising a body portion, a solid corner portion at one end of said body portion having a recess at its inner vertical corner, and an arm extending at right angles from the opposite end of the body portion of one-half the thickness and corresponding in height to the latter, the body portion, solid corner, and arm being provided at their top and bottom edges with communicating grooves, substantially as shown and described.

i. A hollow-wall construction consisting of a plurality of inner and outer intermediate blocks laid in overlapping courses, each of said intermediate blocks comprising a body portion having vertical sides flush throughout their entire length, longitudinal grooves in its top and bottom edges, transverse grooves communicating with the central portions of the longitudinal grooves, and arms extending at right angles from the ends of said body portion of one-half the thickness and the same height as the latter, said arms being provided at their horizontal outer corners with grooves communicating with the ends of the longitudinal grooves, the arms of the outer blocks extending backwardly against the central parts of the body portions of the inner blocks while the arms of the latter extend forwardly against the central parts of the body portions of the outer blocks, thus forming air-spaces the outer and inner set of blocks.

5. A hollow-wall construction consisting of a plurality of inner and outer intermediate blocks and corner-blocks laid in overlapping courses, the corner-blocks being laid at right angles to each other and each comprising a body portion, a solid corner portion at one end of the body having a recess at its inner vertical corner. and an arm extending atright angles from the opposite end of the body portion of one-half the thickness and corresponding in height to the latter, the body portion, solid corner, and arm having communicating grooves in their top and bottom edges; and anchors which engage said grooves.

6. A hollow wall composed of corner-blocks 5 having solid corner portions at one end with recesses and rearward]y-extending right-angular arms at their opposite ends, blocks 4 having severed ends engaging the recesses and t'orwardly-extending right-angular arms at their opposite ends, blocks '3 having severed ends abutting against the severed ends of blocks 4 and provided at their opposite ends with forwardly-extending right-angular arms, an inner set of blocks 1 abutting against one end of blocks 3 4 and against the ends of each other, said blocks 1 being provided at their opposite ends with forwardly-extending right-angular arms, blocks 2 having severed ends abutting against the solid portions of blocks 5 and provided at their opposite ends with rearwardly extending right angular arms which abut against the intermediate inner portion of blocks 1, and an outer set of blocks abutting against one end of blocks 2 and the ends of each other and having their arms abutting against the inner intermediate portion of the inner set of blocks 1.

7. A hollow wall composed of corner-blocks 5 having solid corner portions at one end with recesses and rearwardly-extending right-angular arms at their opposite ends, blocks 4L having severed ends engaging the recesses and forwardly-extending right-angular arms at their opposite ends, blocks 3 having severed ends abutting against the severed ends of blocks 4 and provided at their opposite ends with forwardly-extending right-angular arms, an inner set of blocks 1 abutting against one end of blocks 3 4t and against the ends of each other, said blocks 1 being provided at their opposite ends with forwardly-extending rightangular arms, blocks 2 having severed ends abutting against the solid portion of blocks 5 and provided at their opposite ends with rearwardly-extending right-angular arms which abut against the intermediateinner portion of blocks 1, an outer set of blocks abutting against one end of block 2 and the ends of each other and having their arms abutting against the inner intermediate portion of the inner set of blocks 1.

angular arms, blocks 2 having severed ends abutting against the solid portions of blocks 5 and provided at their opposite ends With for- Wardly-extending right-angular arms which abut against the intermediate inner portions of blocks 1, and triangular cornerblocl;s 6 arranged in alternate courses with cornerlocks 5.
