segmental view of a section of a wall formed;

of blocks shaped or formed in accordance w th my invention placed in proper position. Fig. 2 1s a vertical cross-section of one of the blocks, showing a vertical slotand a transyerse slot for hoisting and lowering the same 1nto position on the wall. Fig. 3 is a top plan view of one of the blocks. Fig. 4 is an under-side plan View of the same. Fig. 5 is a vertical elevation of the hoisting-pin with its slot in the lower end, with the transverse=p=rn adapted to fit in the slot.

These blocks, which are shown on the accompanying drawings in plan view, perspective, and section, are intended for use when sinking a well or shaft and are formed in such manner that, on the one hand, they can be made perfectly tight in the joints, but, on the other hand, will allow all the water which collects during the sinking of a Well or shaft behind the masonry being conducted away, yet when the shaft has been sunk will also permit of the incoming water being led away at difierent heights in the shaft in such manner that, while any bad water which might be found at the bottom of the shaft can be removed, the good water which will come into the shaft can be separated from the bad and be conducted where it is desired to use it. Finally, the peculiar form of the blocks also allows of their being easily placed in position which will avoid any likelihood of charm age to the stones. The stone is formed segmentally, corresponding to the object for which it is used. At both sides it has round fiutings a. On its under side it has a semicylindrical roll or heading 1), Figs. 1 and 2, to

which a similar channel 0 on the upper side of the block corresponds in shape. Both roll and channel do not, however, fit exactly into one another, but the channel is somewhat broader and deeper than the roll, so that sufficient room will be allowed for a suitable quantity of cement, mortar, or the like for fastening the separate blocks together. The block is further provided with two drills or holes, one (1 being a central one extending from the upper part of the block to its lower part, While the other f goes from front to back, and it is advantageous not to have such in the middle of the block, but, if possible, low down; but in any case it cross-cuts the vertical hole or drill.

I11 placing these blocks in position the following procedure should be observed: Into the vertical holes or drills (Z of the stone a key 9, Fig. 5, is placed, which is provided above with a hook or ring 9 and in the vioinity of its lower end has a slit h,whioh key fits opposite to the horizontal drill or boref. A bolt 2', Fig. 5, is then passed through this latter, which goes through the slit in the key, and thereby holds the key in the stone, whereupon the hoisting or similar apparatus is connected with the ring of the key by a cord or rope and the stone is simply lifted into its place. The rounded hollow c in the upper part of the block or stone which lies immediately under the stone which is to be placed in position is previously filled with some kind of cement. The projection or beading 1) on the under side of the stone will then rest in such channel filled with cement and will drive the cement or mortar into every joint or crevice, thereby forming a very tight joint between the horizontal layers of the stones. Then this has been done, the vertical boring d in the stone or block is filled up with a plug of adhesive clay, and this latter is pressed in tightly. Immediately, however, this has been done a rod is pushed in through the horizontal hole or drill f, which has become stopped up at its point of intersection when the drill-hole d was plugged, so that this horizontal hole or drill f becomes again free. The rod is preferably left so long in position until the stopping of the hole or drill d is set hard. If it be then drawn out, a drainage-channel is formed through which the water accumulating behind the wall of the shaft can run 01f, and so the fresh masonry will be protected against being undermined. Between every two blocks orstones a groove 61', Fig. 1, having the form of a tube, is formed by means of the side channels a. This is filled with cement or mortar, whereupon the filling-up material is rammed in as tight as possible, and so that the water may be held back the earth is rammed tight behind the shaft. The cross bores or drills f which have hitherto served for drainage'channels for the water are closed by means of cork, wood, clay, or the like. If at a certain height good water is come upon, the cross-holesf which are in the blocks or stones corresponding to such height have tubes driven into them, whereby the water by means of tubes connected thereto can be led away to the place where it is wanted to be used. The entire set of channels (Z could also he provided with such tubes, and these wherever water unfit for use should enter could be closed by means of screwed caps. In this manner a shaft or well is provided such as cannot be formed by means of bricks, tiles, or hewn stone of a similar thickness and strength, and which has also the advantage that any water [it for use which should enter behind the shaft can without disadvantage to the shaft be brought to any desired place for use, while at the same time any bad water which might arise can be kept away from the shaft.

Having now described my invention, what I claim is- 1. The improved blocks or stones for use in the sinking of wells or shafts, consisting of segmentally-shapcd pieces having side flutings a, a channel 0 at the top, and a corresponding but smaller projection b at the bottom, together with two drill-holes (Z and f, the former of which is placed vertically and centrally, while the latter is horizontal and passes from the front to the back of the block or stone and is formed in the vicinity of the lower edge of the stone and intersects the drill-hole d.

2. A block of stone or analogous material having its vertical sides fluted and provided with a vertical drill-hole (Z and transverse drill-hole f, meeting and crossing each other, substantially as described, and for the purposes set forth.

A block of stone or analogous material having its sides fluted, its upper end being partially concave and its lower end being provided with a convex projection 11, and also with vertical and transverse drill-holes, substantially as described, and for the purposes set forth.

l. In a series of blocks of stone, the combination of side flutings a, adapted to form tubular grooves a for the reception of cementing material, channels 0, and projections 11, substantially as described, and for the purposes set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
