DAM.

Specification of Letters Patent.

Patented Nov. 24,1914.

Application filed January 27, 1913.' Serial No. 744,354..

To all whom it may concern Be it known that I, FREDERICK K. WING, a citizen of theUnited States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Dams, of which the following is a specification.

This invention relates generally to the construction of dams, but more particularly to reinforced concrete dams.

The object of the invention is to increase the stability of such structures and effectually prevent their displacement by the water pressure.

In the accompanying drawings: Figure 1 is a transverse section of a dam embodying the invention. Fig. 2 is a fragmentary rear view thereof, with the concrete partly broken away to expose one of the longitudinal deck-supporting beams. Fig. 3 is a fragmentary front view of the dam, with a portion of the concrete broken away to expose the metallic reinforcements. Fig. 4: is an enlarged fragmentary face view of some of the reinforcing bars and their spacing devices. Fig. 5 is a cross section of said.

bars and devices on line 5-5, Fig. 4.

Similar characters of reference indicate corresponding parts throughout the several views.

1 indicates the buttresses of the dam arranged at suitable intervals and preferably constructed of reinforced concrete and seated in the grooves 2 in the rock or other foundation 3 to prevent sliding thereof. 4 indicates the inclined deck or flooring of the dam also preferably constructed of reinforced concrete and supported upon longitudinal beams 5 which span the inclined front portions of the buttresses at proper intervals. As shown, these beams may be coated with concrete or other appropriate material to protect them from the weather.

The toe 6 of the dam may be widened or thickened in the usualmanner, and is preferably seated in a recess or depression 7 of the foundation 3, as shown, to more reliably anchor it in place. firm and stable part of the dam because it is under the greatest water pressure, and in order to increase the stability of the deck, I tie or anchor the same to the toe by suitable The toe is the most fasteners or connections. For this purpose, transverse metallic anchoring bars are preferably embedded in the concrete and extend- In the (3011-.

ed from the deck into the toe. struction shown, a set of appropriatelyspaced parallel bars 8 extend continuously from the crest of the dam to the bottom of the toe; a second set of such bars 9 alternating with the long bars 8 extend from about the middle of the deck to the bottom of the toe; as best shown in Fig. 3; while a third set of comparatively short bars 10 extend from about the base of the deck to the bottom of the toe.

During the molding of the deck the several anchoring and reinforcing bars are held at the proper distance apart by spacers of any suitable construction. These illustrated in the drawings consist of sheet metal strips 11 doubled at intervals to form feet 12 which rest upon the supporting beams 5 and provided between the feet with tongues 13 which embrace the anchoring bars.

By the construction above described, the toe, being largely held from sliding or displacement by the weight or pressure of the water, in turn resists displacement of the deck and remaining portions of the dam,

thus reliably anchoring the deck as well as the toe in position, without materially increasing the cost of the structure. By embedding the toe in the rock or other foundation, the toe also serves as a cut off which excludes water from the underside of the dam.

If desired, the crest of the darn may be provided with an overhanging portion or apron 14, as shown. In this case, the overhanging portion is preferably reinforced by extending the long transverse bars 8 down- I wardly and rear-wardly into the apron, and

also by additional transverse bars 15 embedded in the apron and extending part way into the deck, say to a point below the upper supporting beams 5, as shown in Figs.

1 and 3. The bars 15 are thus supported by the portion of the deck carried by said beams and in turn carry the overhanging portion of the deck on the principle of the cantaliver.

While the invention is especially applicable to concrete dams, it will be understood that the feature of anchoring the deck to the toe also applies to dams constructed of other materials.

I claim as my invention:

A dam comprising buttresses, longitudinal beams supported thereon, a deck carried by said beams and having a toe, a set of transverse anchoring bars extending throughout the height of the deck and into Witness my hand this 25th day of Januk ary, 1 13- FREDERICK K. WING.
