JOSEPH FEIGENBAUM, OF 1108 ANGELES, CALIFORNIA.

Application filed December 22, 1922.

To all whom it may concern: 7

Be it known that I, Josnrn Finc nnis'mvr, a citizen of the United States residing at Los Angeles, in the county of lies Angeles and State of California, have invented new and useful Improvements in Reenforced- Concrete Hollow-Tile Building Blocks, of which the following is a specification.

This invention relates to building blocks, and has for its object to provide a building block for the erection of walls having air chambers or spaces. Another object is to provide a building block which may be readily assembled and securely connected and reenforced in wall, and which will facilitate the application of the inside finish, such as lath and plaster. Another object is to provide a building block which is of extreme simplicity in design and which may be constructed at low cost of manufacture and which blocks may be readily assembled in the erection of a wall without requirement of specially skilled labor.

Other objects and advantages will be made manifest in the following specification of an embodiment of the invention illustrated in the accompanying drawings, wherein- Figure I is a plan of a corner block of the present invention.

Fig. 2 is an end viewlooking in the direction of the arrow a in Fig. 1. r

Fig. 3 is a view of the opposite end of the block.

. Fig. 4 is an elevation of the inside face of the corner block.

Fig. 5 is a plan of a wall or course block to occupy a position between corner blocks of a course.

Fig. 6 is a perspective of a portion of a wall formed of the presentimproved blocks.

The blocks of the present invention consist especially of a relatively thin front body 2 having a front plane or other surface 3; the upper longitudinal edge of the front body 2 being longitudinally grooved at 4-. and the bottom being provided with a longitudinal tongue or head 5 so that in the su perimposition of the courses of blocks they will be interlocked by the matching of the tongue and grooves. Preferably, the meeting faces of the blocks are bonded with a cement or mortar in the usual manner.

The intermediate or wall blocks, of which one is shown in plan in Fig. 5 and others in perspective in Fig. 6, have on their rear Serial No. 608,500.

faces rearwardly extending perpendicular spacing webs 7 ofany suitable length and thickness and having a height equal preferably to the height .of the front body 2.

A feature of the invention is the arrangement of the transverse webs at such position on each of the wall blocks 2 that the blocks when laid inofrset cor in Fig; 6, will each presen' eir Lransverse webs 7 in alineinent one above the other so that the webs can be reenforced and accurately positioned'by the insertion of vertical reenforcing rods 8 adapted to be threaded through rod holes 9 provided in the webs and extending from top to bottom thereof. As shown in Fig. 5, the transverse webs or spacing portions 7 of the wall blocks 2 are spaced inwardly on the inner face of the block a distance of about one-quarter of the length of the block from each end, so that when blocks have been laid in one course with their ends in abutment, then the next superimposed course when offset in ninetrical relation on the lower course will have their spacing webs vertically alined with thoseof the subjacent course.

When a wall has been built with offset courses of the blocks, the vertical joints in one course will be oiiset relative to the vertical joints of the next course above or below, and the vertical reenforcing rods 8 will be offset relative, to all the joints.

In the construction of walls involving corners or angles, such as shown in Fig. 6, it

may be necessary to employ a corner or special block, and a form of this is shown in Figs. 1 to 4 inclusive in which the front body 2 is provided at one end with a rectangular pillar block 2 which is perforated at its center as by a hole 10 to receive a corner reenforcing rod 11. The corner block is provided with a single transverse and rearwardly extending web which in the erection of the wall will be positioned to register with the subjacent web of a front block 3 in a lower course. i

The corner block 2 is shown as provided with a groove 12 extending from the wall end of the block inwardly tor-ward the corner end of the block terminating at such point as will enable the ready application of a superposed wall block 2. The pillar body forming portion 2 of the block 2 has its top face transversely grooved at 13, therefore, enabling the latching of the corner pillar portions of the blocks and pros as shown viding for a thorough inter-loch of the same.

Strength and rigidity of the blocks is obtained by means of reenforcing wires or rods 15 embedded in the blocks.

To facilitate the fastening of the inside: wall lath L, 5, to the wall construction of the improved blocks, these latter are provided with tie or binding wires 18 projecting inwardly from the ends of the transverse webs or spacers 7.

From the above it will be seen that a wall may be readily erected and will be of rigid and substantial construction by the utilization of the two varieties of the blocks shown in the present case in the construction of a wall having a right angular corner, it being understood that slight variations and changes llltt" be resorted to in the formation of walls of different angles, dimensions and form. 'ihe finished wall, while retaining the desired strength, may at the same time.

he of the hollow or ventilated form, this litin rendered possible by the application of the inside wall body, as lath and plaster, to the inwardly projecting spacing webs or means 7 of the various blocks.

Further embodiments, modifications and changes may be resorted to within the spirit of the invention as here claimed.

vl hat is claimed is:

1. A monolithic, cement, facing block for hollow wall construction, said block having a facing panel from the back of which extend two spacing webs which are disposed inwardly from the ends of the block a. distance of about one-quarter of the length of the block, so that when the blocks are superposed to form a wall with the joints formed between the contiguous side edges of the facing panels of one course spaced with respect to those of the next upper and lower courses, said webs will ver ically registerwith the webs of the upper and lower courses, and reenforcing wires imbedded in said facing panel and extending into said webs.

2. A facing block for hollow wall construction having a facing panel from the back of which extends a spacing web, reenforcing wires imbedded in the facing panel having portions extending into said spacing web, and tie wires imbedded in sail spacing web, said tie wires being looped over the portions of the reenforcing wires therein.

A facing block for hollow wall construction having a facing panel from the back of which extends two spacing webs, which are disposed inwardly from the ends .0 length of the block, so that when the i are assembled to form a wall with ticall v register with the webs of the next upper and lower courses, one of the horizontal edges of the facing panel being provided with a bead and the other horizontal edge being provided with a groove.

i. A facing block for hollow wall construction having a facing panel from the back of which extend two spacing web's, which are disposed inwardly from the ends of the block a distance of about one-quarter of the length of the block, so that when the blocks e assembled to form a wall with stagger vertical joints, the webs will vertically register with the webs of the next upper and lower courses, and reenforcing wires llllbGLltlQCl' in the facing panel having looped portions extending into said webs, there being vertical apertures formed in said webs within the looped portions of said reenforcing wires for the reception of reenforcing rods.

5. A facing block for hollow wall construction comprising a facing panel from the back of which extend two vertical spacing webs which are spaced inwardly from the ends of the blocks a distance of about onequarter of the length of the block for the purpose described, reenforcing wires inrbedded in the facing panel having looped porions extending into the webs, there being vertical apertures formed in the webs within the loops for the reception of reenforcing rods, and tie wires looped over said looped portions and imbedded in said webs.

6. A facing block for hollow wall construction comprising a facing panel from the back of which extend two vertical spacing webs which are spaced inwardly from the ends of the block a distance of about one-quarter of the length of the block for the purpose described, reenforcing wires irnbedded in the facing panel having looped portions extending into the webs, there being vertical apertures formed in the web's within the loops for the reception of reenforcing rods, and tie wires looped over said looped portions and imbedded in said webs, one of the horizontal edges of the facing panel. being provided with a bead and the other horizontal edge being provided with a groove.

In testimony whereof I have signed my name to this specification.
