CURB-BLOCK.

Specification of Letters Patent.

Patenten .nine ie, rais.

Application filed December l, 1916; -Sera11\]'o. 134,440.

To all whom it may concern Be it known that I, WILLIAM Wins, a citizen of the United States, residing at Perham, in the county of Ottertail and State of Minnesota, have invented certain new and useful Improvements in Curb-Blocks, of which the following is a specification.

My invention relates -to curb blocks for constructing wells and has for its object to provide a block which is formed with a recess extending substantially throughout the length of the block for the purpose of providing a step by means of which ingress or egress from the well may be had and which serves to make the block lighter,- thereby economizing in material without greatly reducing the strength of the block. A still further object is to form the lower portion ofthe block so that an extended inclined surface is provided on which the whole foot may rest in a comfortable position, said lower portion extending out beyond the inner surface of the block and sloping back to form a continuous surface with the upper portion of the block immediately below it.

'Ihe full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claim.

In the drawings, illustrating the application .of my invention in one crm,-

Figure 1 is a perspective view of my improved curb block showing the step. Fig. 2 is a plan view of a well with one of the blocks shown insection. Fig. 3 is a vertical sectional view of the well shown in Fig. 2.

My improved curb block is preferably made of concrete and is formed in suitable molds constructed for the purpose. blocks may be made segmental so that a number of blocks 10, of which I prefer to have four, will form a complete circular course, as is clearly shown in Fig. 2. rIhe ends 11 and 12 of each block are rectangular, as shown in Fig. 2, being somewhat higher than wide. The inner surface 13 of each block is formed with a recess 14 extending substantially from one end of the block to the other except for

end portions

15 and 16, while the outer wall 17 and the top and

bottom

118 and 119 are formed smooth. Recess 14 extends back into the block about one-half of the thickness thereof and is bounded by a vertical wall 18, two

sloping

end walls

19 and 20, a curved roof 21 which meets surface 18 substantially in a line and an inclined lower surface 22 of a ridge 23 which extends beyond the inner surface 13 of the block proper and which has a surface 24: sloping back to meet the upper portion of the next lower block and to form a continuous surface with the surface 21 thereof.

In constructing wells a number of the blocks are piled in courses upon one another to break joints on the ground where the well is to be dug. 'Ihe earth is then undermined beneath the blocks which causes the same to sink and to form a lining within the shaft so dug which lining is capable of resisting the pressure of the earth tending to cave the same in and which will not deteriorate with time. The lining may be installed within a wellpreviously constructed of wood or other material without the recially desirable when water is struck and the operator cannot stand upon the ground to work but must remain supported upon the wall structure. In climbing it will be found that with only four blocks to the course and with a recess of considerable circumferential extent, that a succession of steps will be provided which are substantially one below the other even though the blocks are laid to break joints, thus permitting the operator. to move straight up ward with the greatest ease.

'Ihe advantages of my invention are manifest. The blocks can be easily molded by a simple mold since a perfect draft is secured in any portion of the same. It will be noted that the block is formed with the major mass of the material at the bottom, which permits of proper setting of the cement without danger of the wall structure breaking down during setting, and also gives the block the greatest strength.

I claim:

A curb block for wells comprising a body portion having a circumferential de ression formed with an inclined lower sur ace and a curved wall extending from the top of the 'block inward toV the inner part of the positioned below it to form :L regular condepression, and a `ridge formed along the tinuous surface therewith, lower portion of said block proj ectng out In testimony whereof I aiiiX my signature beyond the same having a surface serving in presence of two witnesses.
