' Specification of Lettei's Patent.

applicationfiled May 12, M21. aerial Ito. aeaaea To all whom it may co mern:

Be it known t at l, TnoMAs CoLosIMo, a citizen of the United States, residing at Gary, in the county of Lake and State of Indiana, have invented new and useful Tmprovements in Building-Blocks, of which the following is a specification.

This invention relates to building blocks and has for one of its objects the provision of an article of this kind, made from cement or artificial stone and the like, which is provided with recesses and tongues where by an interlocking joint is formed to securely bind the adjacent blocks together.

A. further object of the invention is the arrangement of vertically disposed air spaces having a length greater than onehalf the length of the block, thus permlttm a free circulation of air through the wal s of the block when the latter are arranged in staggered relation with respect to each.

other. The air spaces thus formed in the block are so arranged as to be at all times in alinement with the corresponding alr spaces in the blocks immediately above and below.

Another object ofthe invention is the provision of longitudinal centrally disposed grooves or recesses in the upper and lower faces of the block which are connected together by a vertical recess located at one end of the block, while the OPPOSlteelld is provided with an extending tongue of less length than the recess to which it engages in the adjacent block, thus forming an air space which, together with the longitudinal grooves, in the upper and lower fafies of t e oppositeend of the block, tend to form a continuous air space around the entire block.

In the drawings:

Figure 1 is a perspective view showing a corner wall construction of the blocks.

Fig. 2 is a top plan view showing the locking connection of two of the intermediate blocks.

Fig. 3 is a top plan view showing the looking connection of a corner bloclz. v

' Fig. 4: is a longitudinal sectional view taken on the line 4-4 of Fig. 2.

Fig.5 is a sectional view taken on the line 5-5 of Fig. 2, and

Figs. 6 and 7 are elevational end views taken from opposite ends .of the blocks.

Referring more partlcularly to the accompanying drawings in which like reference characters indicate similar parts, 10 indicates a block preferably of rectangular formation and made of any suitable material such as cement or artificial stone and the like. A pair of

longitudinal grooves

11 and 12, respectively, are arranged in the upper and lower faces of the block 10 and are connected together at one end of the block by a vertical groove 13. The groove 13 communicates with a wedge shaped recess 14; formed in the same end of the block, while in the opposite end is formed a tongue 15 of less length than the depth of the recess 14:, so that when it is interlocked with a recess in adjoining block, there will be formed an airspace around the entire block.-

Vertically disposed

air spaces

16 and 17 are arranged on each side of the

longitudinal grooves

11 and 12 and communicate therewith. The length of the

Vertical recesses

16 and 17 is preferably greater than one-half the length of the lolocks so as to permit, when the blocks are arranged in staggered relation with respect to each other, a free circulation of air through the walls,

thus preventing dampness and other injurious effects brought about by lack of proper ventilating means in blocks of similar construction.

To provide for a corner block which interlocks the ends of a series of blocks arranged at right angles toone another, ll employ a corner loloclr 1 8 having a. plain outer end 1.9,and a side 20 with awedge shaped recess 21 arranged to interlock with a tongue 15 located at one end of one of the blocks 10.

It is to be understood that the corner block may be constructed in any desired manner, governed by the particular iormationof the corner intended to be formed. As shown in Fig. 3, the block is arranged at a right angle to the adjacent block, however, it may be constructed at any angle, depending upon the angular position desired.

The other parts of the corner block are ill) avail myself of such changes and alterations as fairly fall within the scope of the appended claims.

I claim:

1. A building block comprising a body portion having Vertically disposed air spaces on opposite sides of its median line, and of a greater length than one-half the length of the block, a continuous centrally disposed groove in two sides vand one end of said block, a recess formed in one end of the block and communicating with said groove, and a projection at the ,other end of said block of less length than the depth of said recess.

disposed groove in twosides and one end of said block and communicating with said vertical air spaces, a recess formed in one end of the block and communicating with said groove, and a projection at the other end of said block of less length than the depth of said recess.

y In testimony whereof-I have hereunto set no hand.
