WALL CONSTRUCTION.

Specication of Letters Patent.

Patented Aug. 31, 1915.

To all1 whom it may concern.'

Be it known that we, J osnrH LEHIGH JEN- SEN and Nuns ARTHUR OLSON, citizens of the United States, residing at Council Bluffs, in the county of Pottawattamie, State of Iowa, have invented a new and use ful Tall Construction, of which the fol 4 lowing is a specification.

This inventionrelates to wall construction, one of the objects of the invention being to provide blocks of plastic material and which are of novel form so that, when the blocks are assembled, those blocks forming one course will interlock with lthe blocks forming the next adjoining courses, each course serv-ing as a retaining means for the course thereunder, so that, when the blocks of one course are secured together, outward movement of the blocks of the next course thereunder is prevented.

A further object is to provide a wall 'construction utilizing tying means which is completely housed in the blocks and which serves to bind together the blocks of each course. l

Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being 'understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

lfn the accompanying drawings the preferred form of the invention has been shown.

In said drawings: Figure 1 is a plan view of a curved wall made up of blocks such as constitute. the present invention. Fig. 2 is a section online A-B Fig. l. Fig. 3 is a perspective view of one of the blocks.

Referring to the figures by characters of reference 1 designates a block of plastic material preferably formed with an opening 2 other, one side of the block being preferably slightlyconcaved Wh'ilethe other side of the block is .preferably slightly convex so that, when the'blocks are assembled, they will fit one within another, as shown particularly in Fig. 1.. The outer portion of the upper end of each blbck is removed tov foi-'rifa fiat ledge 3 parallel with the end of the block,

said ledge being overhung by an inclined shoulder 4; extending throughout the width of the block.v Thev portion of the lower end of each block is cut away so as to form an 'inclined shoulder'which is parallel with the overhanging shoulder 4, all of the upper and lower faces ofthe block being in parallel lanes. AExtending transversely .through t e lower end portion of the block is an opening and, when a series of'blocks are assembled, theopenings therein will register so that it thus possible to thread a tie cable 7 or thelike through the openings. .i

In erecting Va wall a course of blocks 8 is placed on thel foundation, these blocks 8 being similar to those herei'nbefore described, with the exception that the lower ends thereof are not-cut away. These blocks of the lower course are held together by inserting atie device? 'through the registering openings 6. A second course `of blocks is mounted on the blocks 8, the shoulders 5 of these blocks of the second course extending under the overhangs ,4 on the blocks of the lower course. A tie 7 is then inserted through the openings 6 in the blocks of the second course and, when tightened, will not only draw the blocks 1 tightly together but will also bind shouldersA 5 tightly against the overhangs 4, Consequently the Aupper ends of the blocks 8 will be prevented from pressing outwardly. The other courses are then placed in position in the manner herel inbef'ore described. Thus it will be seen that a wall is produced whichlis capable of res isting extreme'outward pressures, each tie device being soplaced as to constitute a reinforcing and tying meansfor the meeting portions of two courses of blocks. Furthermore the tie devices are completely concealed where they are not exposed to the weather. By using these tie devices and by forming the blocks with interfitting sides,

it becomes unnecessary to employ cement or other means for iilling in between the blocks. I

1. A wall construction made up of superposed courses of blocks, the blocks of one course having upwardly and outwardly inclined overhangs upon their upper ends and the blocks of the next adjoining course thereabove having a. depending projection formed by downwardly and inwardly inclined shoulders extending outside of and under the overhangs there being an aperture extending through each projection, and a tie ilo device extending through siii-d apertures 'and outside of the engaged portions of the blocks 01' the next adjoining course thereunder.

2. A wall construction consisting of a. course of blocks, each block having its upper end formed with an outwardly and upwardly inclined shoulder, and an upper course of blocks resting upon said first mentioned course, each block of the upper course being provided with an inwardly inclined shoulder extending outside of and inwardly and a tie device extendingcontinuously through said registering openings whereby the shouldered portions'of the blocks of the upper course are prevented from shifting In testimony 4that/We claim the foregoing as our own, We have hereto allixed our signatures in the presence of two witnesses.
