Specification of Letters Patent.

Application filed February 23, 1905. Serial No. 246,991.

To all whom it may concern:

Be it known that I, FRANK D. Gmnnves, a citizen of the United States, residing at Fort Collins, in the county of Larimer and State of Colorado, have invented a new and useful Water Head-Gate, of which the following is a specification.

This invention relates generally to water head-gates, and particularly to a novel form of attaching means for assembling the conduit or pipe with the head-plate of the gate.

The object of the invention is in a simple, thoroughly feasible, and practical manner to combine the conduit with the head-plate of a gate in such manner as positively to hold it against shifting, to distribute the strain of the attaching means upon the rim of the conduit, thereby to reduce liability of breakage, and to insure such cooperation be tween the end of the conduit and the headplate as will prevent leakage.

WVith the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a water head-gate, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable ofv carrying the same into practical operation, it be ing understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof.

In the drawings, Figure 1 is a view in perspective of a water head-gate constructed in accordance with the present invention eX- hibiting the manner in which the pipe or conduit is combined therewith. Fig. 2 is a view in vertical transverse section, the conduit being omitted. Fig. 3 is an enlarged detail sectional view showing more clearly the manner in which the conduit is combined with the headplate.

The frame of the head-gate comprises two uprights l constituting guides, between which work a gate 2, the same being actuated by a shaft or rod 3, one end of which is secured to the gate in any suitable manner, and the other end of which projects through a brace 4, connecting the upper ends of the guides, and through an intermediate brace 5. The upper end of the rod is threaded for the reception of two hand wheels 6 and 7, one of which is disposed above the brace and the other below it, and are adapted, respectively, to reciprocate the rod 3 and to lock it against reciprocation. The general description herein given is that of the head-gate, for which I received Letters Patent in the United States, No. 779,541, dated January 10, 1905. It is to be understood, however, that the present invention is not to be limited to its combination with the particular form of framework and gate shown, as itmay be applied to other forms of head-gates and still be within the scope of the invention.

The present invention resides in a novel form of attaching means for combining the pipe or conduit 8 with the head-gate. This is secured by the provision of a head-plate 9, which may be of any suitable material, pref erably of cast-iron, and is held between the guides by bolts 10, the said plate being provided with an opening 11, commensurate in area with that of the bore of the pipe 8. Proj ecting from one side of the plate 9 and at right angles thereto is a series of lugs 12--in this instance, fourwhich are reinforced against yielding by brace-webs 13. These lugs are by preference cast integral with the head-plate; but, if preferred, they may be made as separate elements and secured thereto. The inner faces of the lugs are smooth and are engaged by wedges 14, provided with inclined or curved faces 15, to engage with the shoulder of the pipe-rim 16, as shown in Fig. 3. Each of these lugs is provided with a longitudinal opening, through which projects abolt 17, having one end provided with a head 18, which is seated flush with the outer side of the face of the head-plate, the other end of the bolt being projected through the wedge and provided with a nut 19 to cooperate with the wedge in forcing the same into engagement with the shoulder of the rim. The bolts will in practice be made of a length to extend some distance beyond the wedges when the latter are positioned, thus to adapt the attachment for use in connection with pipes or conduits having rims of different sizes.

In the use of the device the nuts 19 and wedges 14 are removed and the conduit is placed against the head-plate, after which. the wedges are again placed upon the bolts and the nuts are applied and tightened. In the act of seating the nuts the inner faces 15 of the wedges ride up upon the shoulder of the rim, and thus not only force its end tightly against the head-plate, but also center the pipe relatively to the orifice 11. By the employment of four wedges, as shown, it will be seen that the strain upon the rim is distributed, thereby lessening the danger of causing any fracture by uneven strain. Of course, if preferred, a greater number of lugs and wedges may be employed, and as this will be readily understood detailed illustration thereof is deemed unnecessary.

Having thus described the invention, what is claimed is 1. In a water head-gate, a head-plate provided with integral lugs, wedges engaging the inner faces thereof, and means for securing the wedges in position.

2. In a water head-gate, a head-plate provided with integral reinforced lugs having fiat inner faces, wedges engaging the said faces, and means for securing the wedges in position.

3. In a water head-gate", head-plate provided with integral lugs, bolts projecting through the plate and disposed parallel with the inner sides of the lugs, wedges mounted upon the bolts, and clamping-nuts carried by the bolts and engaging the wedges.

4. In a water head-gate, a head-plate provided with integral lugs, bolts projecting through the head-plate and extending parallel with the inner faces of the lugs, wedges engaging the bolts having their inner faces beveled or curved, and nuts carried by the bolts and engaging the wedges.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

FRANK D. GIDDINGS.
