useful Improvements in Hydraulic Giants,

and I do hereby declare the following to be a full, clear, and exact description of the same. My invention relates to improvements in hydraulic giants.

It consists in an improvement in the ilexible joint, and is particularlyapplicable to the form of giant described and illustrated in my Patent No. 583,806,6lated July 20,1897. It also consists in the other details of construction which will be fully described hereinafter, and pointed out in the claims.

The object of my invention is to provide a cheap, simple, and efficient hydraulic giant so constructed that the lines of strain-induced by the outrushing stream shall be brought low down toward its foundation, and, further, to so provide in its construction that the outilowing stream shall not be cramped or impeded by the vertical movement of the movable section or nozzle. I accomplish these objects by means of devices illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my device, portions being in section to more clearly illustrate it. Fig. 2 is a detail of the ball-bearing joint.

A represents the stationary portion of a hydraulic giant, preferably made in the form of an upturnedy elbow, in the lower portion of which the supply-pipe terminates. The upper portion of this pipe or elbow is provided with a spherical segment or socket. Surrounding this socket is an exterior flange or lip a., in the under side of which is located a circular track, groove, or Way a', adapted to receive and contain antifriction-balls. Surrounding the socket portion of the pipe A is a ring B, preferably formed with a flange or lip b, projecting inwardly beneath the flange or lip a. In the ring B is provided a track,

groove, or way b', corresponding with and opposing the track ct, so arranged as to be adapted to receive between them antifriction-balls. The lower face of the flange a and the upper face of the iiange b are slightly separated and are preferably formed at an angle to the horizontal plane, substantially as shown in the detail Fig. 2, in which the opposing faces are approximately at forty-ve degrees to the horizontal plane. For convenience of construction the ring B is usually made in two parts, which parts are joined in any suitable way, preferably by a bolt, as shown at b2. In the ring B is provided a bearing, (shown dotted in Fig. 1 at 53,) one of such bearings in each of the two parts which form the ring B.

The movable section C of the giant is of curved and tapering form, as shown in Fig. 1. At its lower portion it is provided with a spherical segment c, adapted to loosely fit the spherical socket of the lower stationary pipe A and form a ball-and-socket joint therewith. Each side of the curved movable section C is provided with a pin c', suitably secured theressv to and adapted to enter and engage with the bearings b3, thus forming a pivotal support for the movable section C upon the ring B. The lower opening of the spherical segment c is preferably frog mouthed or scarfed, as shown in Fig. 1.

To prevent leakage in the ball-and-socket joint, a suitable packing7 consisting of aiieXible packing-ring D and a metallic holdingring d', is provided. Antifriction-balls E are provided in the tracks or ways a' and b. By the construction here shown depressing the outer end of the curved movable section does not contract the available waterway, as in giants heretofore constructed, and reversing the position of the ball and socket from the way heretoforeconstructed carries the point of suspension much closer to the foundation than it has been possible heretofore. The angular form of the faces of the iianges aand b perform the desirable function of holding the ring B in place by providing metal in the flanges a and b to overhang the horizontal diameter of the antifriction-balls below and above, respectively.

The operation of the device is, speaking generally, the same as that of a hydraulic giant of ordinary form, except in regard to the effect of the construction particularly referred to herein. It is obvious that by having the male portion of the ball-and-socket joint a part of the movable section the section of the stream in the movable section does not vary by the vertical movement of its outer IOO end, asin the form of construction heretofore employed. Any diminution of the Section which might take place in the stationary elbow by reason of the vertical swing of the movable section is provided for by the frog-mouth or searfed shape of the Water-inlet to the ball of the joint, a shape which is impossible in the ordinary form of construction. The angular character of the adjacent flange-faces simplifies the construction by obviating any special device to keep the ring B in working position.

Having now described my invention, WhatI claim as new, and desire to secure by Letters Patent, is

l. A hydraulic giant comprising a stationary pipe having a socket, a curved movable JESSE R. EOFF, B. J. BAUM.
