STEEL WATER-GATE.

srncrrrcnrron arming pm of Letters Patent No. 650,502, dated May 29, 1900.

Application filed February 28, 1900. Serial No. 6,839. (No model.)

To all whom it may concern:

Be it known that I, JOHNO BOUSE, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Steel Water-Gates and I do herebydeclare the following to be a full, clear, and exact description of the same.

My invention relates to improvements in gates of that class which are designed to control the iiow of water under pressure or otherwise; and the object of the invention is t0 provide for an improved and lighter construction, with means for dismountin g the parts to reduce the weight for transportation in difficult places.

It consists in details of construction, which will be more fully explained by reference to the accompanying drawings, in which- Fignre l is a front elevation of my apparatus. Fig. 2 is a transverse section. Fig. 3 is an enlarged detail view of the upper part.

For the control of water flowing in large pipes and often under high pressures transversely-movable gates are employed, these gates being introduced between the pipe lengths at points where they are required.

It has been customary to make the casings and general structure necessary for guiding and operating the gates of cast-iron, which must be made thick and heavy to resist the pressure brought upon it. In my invention I make the casing of sheet-steel plates cut into proper shape, with a peripheral frame of channel or angle iron, to which the plates are riveted, peripheral angle -iron frames surrounding the meeting edges and forming the junction of the segments of the casing, and independent pipe connections of steel tubing adapted to screw into the valve-seat and corresponding ring upon opposite sides ofthe casing, these tubes having wrought-iron fianges iixed to their outer ends, by which they are connected with the adjacent pipe-sections at points where the gate is to be introduced. As here shown, the casing is in the form of an ellipse made of two parts l and 2, the part 2 carrying the valve-seat 3 and having the connecting tubular sections 4 projecting from opposite sides. The part l forms a segmental cap or cover, which is bolted upon the part 2, and the valve-stem 5 extends up through a the valve-stem. The sides of the casing l and 2 are made of sheet-steel of suitable or desired thickness to resist the pressure which may be brought upon them. rihe periphery of this casing is formed of channel or angle iron 8, the web of which is of suiiicient width to provide for the required distance between the sides of the casing, and the flanges of the channel-iron are bored coincidently with the periphery of the plates, and these are riveted upon the channel-iron, thus forming the segments of the casing. If angle-iron is used, the rim will be made of sheet-steel riveted thereto, as shown in Fig. 2. The segments l and 2 have each the bands or frames 9, which are made of angle-iron bent into rectangular form and surrounding the open meeting ends of the segments to which they are riveted, so as to give the sides suiiicient resisting strength at this'point. The other flanges of the angleiron bands turning outwardly, as shown, meet and are bored to receive bolts by which they are secured together, thus uniting the casing into a solid structure. Y

When the gates are very large and the pressure great, I employ T-irons 0r strengthening-pieces 10, which extend across the upper part l of the casing in opposite directions. The interior T-irons will be riveted vertically within the sides of the casing, and the exterior irons will be riveted transversely across the outside. The lower part 2 of the casing has openings made in -the sides of a diameter to correspond with that of the pipe with which the gate is to be connected. Vithin these openings are bolted the brass ring 3, which forms the valve-seat, upon one side and a corresponding ring 11 upon the opposite side. This ring may be made of wrought-iron, and these two rings surrounding the openings in the sides of the case serve to give it the necessary strength and also to receive the screw-threads which are formed in their inner peripheries.

The pipe-sections 4 are made of tubular steel and are screw-threaded at the inner ends, so as to screw into the rings 3 and ll, and being thus screwed in they are removable at any time to reduce the size of the ap- ICO paratus for transportation. Around the outer ends of these tubes are secured the ring-l iianges 12, having bolt-holes around the periphery to make connection with the adjacent pipe ends when the gate is in.: place.

These rings orlianges serve also to strengthen Aextending approximately at right angles beA tween the two sides.

The valve-stem 5 passes through the-stult-- ing-box 13 at the top of the casing and thence upwardly through a hole lnade in the top of the channel-iron frame 7 and through the nut 6,Y the upper part of the stern being threaded, so that when the nut is turned it will canse the yvalve-stem to be moved through the nut to either open or close the valve without itself rotating. the valve lis very considerable, it is desirable to provide some means for relieving the friction otherwise incident upon the turning of the nut. This I effect by means of rollerbearings fitting between the angeof the nut and the surfaces between which it is turnable. This fiange is of sufiicient diameter to receive the tapering rollers 14 above and below it. These rollers have a taper, with 'the center of the valve-stem as the point 'of their convergence, and the flange ot the nut projects into a cap 15, which is boltedy upon the seat 16, so that there will be sufficientsp'acebctween the flange of the nut and the capabove and the seat below to admit' the beveled rollers 14. The objection to.ithe use of ballsor rollers at such points usually arises from the fact that these parts are frequently separated, and unless the antifrictional devices are in some way prevented from dropping out they are liable to be lost.

In my invention'the rollers have short pro-V jecting shafts or spindles 17 at the end, and these enter corresponding,openings made in the cap 15 and vbetween it and the seat 1G, so that if the cap is removed neither set of rollers would be allowed to fall out.

'The cap 15 is made in two annular rings, the lower ,one of which partially incloses the flange Yof the nut'G, while the upper one projects "over the flange and is chambered to receive the rollers 14 and-the upper halt of their spindles', the lowcrhalf of t-he spindles rest` As the pressure upon which surrounds the lower part of the flange, is riveted tio the seat 16, and thus retains the lower set of rollers in place, so that whenever the cap 15 is removed or the nut is removed the rollers and cap and those in the seat will remain in place Yand cannot be lost.

I have described the frame which forms the periphery of the case-segments as made of channel-iron, which is preferable, because the web between the iianges forms the outer periphery of the case. It will, however, be understood lthat this frame could be made of angle-iron strips bent to the proper shape, and the space between the flanges could be filled 'by a sheet or sheets of steel cut and bent to properform and riveted to the angleiron pieces, which would, in effect, produce the channel-iron'after the parts were secured together. I do not wish to limit my construction to either form, as I consider one the equivalent of the other, and in like manner I do not limit the construction of the supporting-flange rings or the rings which surround and strengthen the tubes 4to anylpartieularform of metal, as it would be manifest that any of the well-known metals, either east or wrought, may be employed with the Aresults usual to the use of such metals.

Having thus described my invention,`what I claim as new, and desire to secure by Letters Patentfis- 1. A water-gate easing including upper and lower members formed of angle or channel iron, means uniting the meeting edges of the members, and sides formed of sheet metal andriveted to the members. Y
