JOHN oniiwronn, OF MILLINOCKET, MAINE.
CEMENT BUILDING-BLOCK.
Specification f Letters Patent.
Patented Feb. 9, 1909.
Application filed June 3,1908. Serial No. 436,527
To all whom it ma concem': 4
e it known t at I, JOHN CRAWFORD, a. subject of the King of Great Britain, residing at Millinocket, in the county of Penobscot and State of Maine, have invented new and useful Improvements in Cement Buildinglocks, of which the following is a specification. 4
My invention relates to improvements in cement building blocks, and its primary obj cct is the provision of building blocks which are constructed to provide a continuous air space when. the blocks are assembled in wall formation, the air space preventing the passage of heat, cold or moisture through the wall.
provision of a cement building block which is simple, durable and eflicient, and which may be manufactured and sold at a comparatively low cost.
With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinaftcr fully described, claimed and illus trated in the accompanying drawing, wherein:
Figure 1 is a view in side elevation of a wall constructed of building blocks made in accordance with my invention. Fi 2 is a top lan view of corner and side we 1 building blocks, illustrating the manner in which the blocks are assembled to form a corner Fig. '3 is a sectional view taken on a plane extending vertically through a wall formed of building blocks constructed in acco rdance with my invention. Fig. 4 is a detail top plan view of the corner block. Fig. 5 is a view in side elevation thereof. Fig. 6 is a View in end elevation of one of the side .wall blocks, and Fig 7 is a top plan view thereof.
Referring to the drawing by reference numerals, 1 designates a building block which is adapted to be constructed of suitable proportions of cement and sand, and which Jnay be of any size. The relatively outer surface of the building block may be glazed or otherwise suitably ornamented. The building block is provided in its relatively lipper and lower surfaces with longitudinally extending recesses 2', which open out through the ends of the block and which are substantiallyV-shaped in cross-section. The recesses are respectively arranged adjacent the relatively inner and outer surfaces of the block and extend inwardly beyond the. transverse center of the block. The
A further object of my invention is the ends of the block are provided with recesses 3 which are coextensive in height with the hei ht of the block and which communicate Wit the ends of the recesses 2.
The corner block 4 is provided with L- shaped recesses 5 which respectively open out through the relatively upper and lower surfaces thereof. The recesses 5 extend from one end of the block to the relatively inner side 0f the block at a point adjacent the other end thereof and communicate with recesses 6 and 7 which are formed in one end of the block and in the relatively inner side thereof, respectivel The recesses 6 and 7 are coextensive in eightsvith the height of the block and the recesses 5 extend inwardly beyond the transverse center of the block. The relative arrangement of the recesses is such that a continuous air space is provided in a wall built of the blocks. The recesses 2 and 5 provide air s aces which extend horizontally of the yval while the recesses 3, 6 and 7 provide air spaces which extend vertically of the wall and which establish communication between the horizontal passages of the respective courses of the wall. As the horizontal air spaces extend inwardly beyond thehorizontal. center of the block, and as the vertical spaces are arranged at the meeting ends of the blocks, it should be apparent that the wall is provided with a continuous air space which will efiectively resist the assage of moisture, heat and cold through t e wall. 9 v
Changes in the form, proportions and minor details of construction may be made within the sec e of the claims without departing from t e spirits or sacrificing any of the advantages of the invention.
Having fully described and illustrated my invention, what I claim is:
"1. A building block provided with recesscs extending throughout its entire length, one of the recesses opening out through the upper and the other out through the lower surface of the block, one recess being located near the inner surface and the other recess near the outer surface of the bloclgsaid block being provided in its ends with recesses which open out through its upper and lower surfaceshand communicate with the ofil'Sllnamed recesses.
2. A building block provided with substantially V -shaped 'recesses extending throughout itscntire length, one of the recesses opening out through the upper and the other-out through the lower surface of i In testimony whereof I effix my signature ghe black}; 12%6 recesseis extendilg inward? in presence of two Witnesses.
e on t e orizonta center 0 t e 0e sa i block being provided in its ends with JOHN CRAWFORD 5 recesses which open out through its upper Witnesses:
and lower surfaces and communicate wlth E. E. WYM1 \N, the first-named recesses. K. ALLEN.
