Specification of Letters Patent.

l Patented Dec. 3, 1907.

Application 'lled September 24. 1906. Serial No. 335.987.

To all whom it may concern:

Be it known that I, JAMES STANwooD PIERCE, citizen of the United States, residing at Tacoma, in the county of Pierce and State of Washington, have invented certain new and useful Improvements in Cement Blocks; and do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in wall construction, and my prime object is to constructthe walls of plastic blocks and to provide suitable means for securing the blocks together.

. Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings which form a part of this application, Figure 1 is a side elevation of a section of wall constructed of myimproved blocks. Fig. 2 is a longitudinal vertical sectional view thereof. Fig. 3 is a top plan view of the wall. Fig. 4 is a sectional view as seen from line 4-4, Fig. l, and Fig. 5 `is a perspective view of one of the blocks.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates the blocks from -Which the wall is constructed, said blocks being preferably composed of plastic material, such as cement or the like, and when the blocks are molded they are'provided upon opposite sides with grooves 2, and disposed through the blocks at the center of each of the grooves 2 are W en t ey are roperly assembled together, the grooves 2 of each tierwill register with the grooves' of the opposite tier and the openings 3 likewise register with each other when the blocks are properly assembled.-

In constructing a wall from the form of block herein shown, the first layer of blocks are` properly placed upon the ground or specially prepared foundation, after which asimilar layer is disposed on to of the first layer-and are'so arranged that t e center of the blocks of the second layer is directly over the meeting end of the blocks in the lower la er, thereby breaking the joints between tlire several layers. Before disposing the blocks of the second layer in position, a girder 4 is disposed in each of the grooves of the several blocks and are of suflicient thickness to extend substantially half their height above the upper edge of the block, and in this manner it will be seen that when the next layer of blocks is disposed in position on the first layer, that the girder will be entirely inclosed between the two grooves.

As best shown in Figs. 3 and 4, the wall consists of three tiers of blocks disposed side by side, and the 'girders are of suiiicient length to engage all three of the tiers. To more securely bind the several tiers and layers of the blocks together, I dispose a plurality of shafts 5 through the several registering o enings in the blocks. The girders 4 are a so provided with openings through which the shafts' also extend, thereby securely locking all of the blocks together and forming an exceedingly compact wall. When the blocks are used for forming walls of buildings, a portion of the girders 4 may extend from one wall to the other, thereby forming means for su porting the floor, and as the girders 4 and) shafts 5 are preferably constructed of metal, it will be seen that a building may be constructed with the use of very little lumber or other inflammable substances,

thereby rendering the structure iireproof. It will be seen also that this form of block together with the means for securing the same together is particularly adapted for use in building dams, sea walls and the like.

It will now be seen that l have roduced a cheap and durable form of bloc whereby the same may readily be disposed in position and permanently secured together, and one wherein the blocks may be completed with one operation of the mold.

What'l claim is: 1

' 1. A wall formed of plastic blocks laid in superposed layers and each block formed with grooves upon opposite sides and openings with the grooves and openings registering girders disposed in coincident registerlng grooves, and disposed transversely of the length of the blocks, there being two girders' to each block, and tie shafts passed through the openings of the blocks and coincident openings in said girders, and extended at right angles to the girders.

2. A wall formed of plastic blocks laid in superposed layers and each block formed with grooves upon opposite sides and openings with the grooves and openings registering girders dis osed in coincident registering grooves an dlsposed transversely ofthe fg me@ Ie'ngthhof the blocks, there being two girders In. testimony whereof I have signed my to eacholook,v and tie shafts passed through name to this specification inthe presencelof the openings of the blocks and coincident tWo subscribing Witnesses. v y openings in said. girders and extend-ed at JAMES STANWOOD PIERCE.
