To all whom it may concern:

Be it known that I, J osEPH M. ALLENwooD, of Timbuctoo, in the county of Yuba and'State JOSEPH M. lALLEnwrifop,' or lritrt-rcjroo, cAIJIFoRNImJAssIGNon, BYgMEsNn I EASSIGNMENTSJO JOSEPH CRAIG- iM'PROVEMrNTIIN ORE-WASHING APPARATUS VFor' HYDRAUUC MINING-.ifV i 'speeicenon forming para of Letters 'Patent No. 43,2168', daten July 12, 1st-i 5v Reissue No. 5,255, dated .military 28, 187.3; Reissue No. 8,037, dated 'January 15, ISYS.; application filed Januar'yQ, 187.8." i

of California, have invented an Improved Hydraulic Machine for Washing Ores, of which the following specicationis a full, clear, and exact description, reference being had to the accompanying drawings.

Myinvention relates to certain improvements in machines for directing a stream of water under pressure against a bank of earth, cement, or gravel, for the purpose of cutting I away and tearing down the bank, and for the further purpose ,of disintegratin g the earth,

sand, or gravel.

These machines receive and discharge the water under a high pressure, so that the water issues from the nozzle with great force.

The pipe through which the water is conducted to the machine lies upon the ground, so that it is found necessary, for convenience, to make a bend ongoose-neck before attaching the discharge pipe and nozzle, in order to admit of the nozzle being ranged up or down,

or to either side, for the purpose of directing the stream. This bend in the pipe imparts to the stream of water a spiral motion in the discharge-pipe, so that when it issues from the nozzle. it scatters, so as to spoil the efective ness of the stream.

My first improvement remedies this difficulty; and it consists in the placing of diaphragms in the pipe, which serve to straighten the stream after it has passed the bend above described and before it leaves the nozzle.

Another difficulty which, before my improvement, attended the employment of these hydraulic nozzles, was the amount of power required to move the discharge pipe and nozzle in a horizontal direction when it was desired to change the direction of the stream of water. The rigidity of the body of water in the pipe and nozzle was such that it required the eX- ertion of great force to swivel the discharge pipe and nozzle after it was once started into action.

The machine, as I originally constructed it, was provided with a exible hose-section for connecting the discharge-pipe with the nozzle, so that the hose-section formed a part of the nozzle, and ls'erved as a f joint vto'render the nozzle flexible; It was soon- 'discovered' by those who usedfinyZ machine, thatif the'nbzzl'e y should by any means, accidental 'or otherwise, get turned to'an angle to the discharge-pipe, the force of the water would cause the discharge pipe and nozzle to fly suddenly in an opposite direction, and this action was characterized by the miners as bucking This led to the further discovery that if the nozzle was gently turned against or cramped upon the stream of water in either direction, the

force of the stream of water passing through the discharge pipe and nozzle would cause them to move slowly in an opposite direction, and thence forward. The machine was thus used where any difficulty was experienced in moving the nozzle by main strength.

In the accompanying'drawings, A, in elevation, section, and plan, represents a main pipe leading to the reservoir and conducting the water to the place of operation. At S, Fig. 3, is shown a screw, for the purpose of detaching the upper portions at pleasure; C, in Fig. 3, is a pipe fitted over P, and upon which C revolves with a water-tight joint, and, being bent at right angles to P, can be turned to any desired point of the compass. (See V V, plan, Fig. 1, Where .D D D D D D represent hook-headed bolts for holding C in its place; see D D, Fig. 2.)

In plan,^Fig. 1, at B B, are shown two foundation-sticks, locked together at right angles, for supporting the other parts of the apparatus, and to which they are attached by the fastening marked H in elevation and section.

At E E, in Figs. 2 and 3, are shown four braces for adjusting the parts in a proper position. These braces are provided with a socket and screw, whereby they can be shortened or lengthened at pleasure.

At R, in Fig. 3, is shown a short piece of hose, composed of some kind of flexible material, such as rubber or canvas, whereby the discharge-pipe N can be elevated or depressed, so as to direct the discharge to any desired elevation, While by bending the nozzle ordischarge-pipe N to either side the force of the stream of water passing through the discharge-pipe will cause the pipes C N to be swveled in an opposite direction upon the joint D. v

To accomplish this all the attendant has to do is to brace against the outer end of pipe G with one hand, while he bends the nozzle N t toward him slowly with the other hand. As soon as the pipe is cramped upon the stream of water, the force of thewater acting upon the outer bent pipe will cause-both the pipes (l and N to move in an opposite direction until it has arrived in the desired position.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The method of operating'hydraulic nozzles in order to change their horizontal direction, consisting in cramping the pipe or nozzle upon the stream of water which is passing through the discharge-pipe, so as to-move the v machine in an opposite direction by the force of the water passing through the dischargepipe, substantially as-above specified.

- obtained, substantially as 2. vThe combination of adisc'harge-pipe pro- Y vided with guides or diaphragms, andthe elbow C, connected by a working joint with the :supply-pipe A, substantially as and for the purposes above specified.

3. The combination of two elbows, C A, with the swiveling joint D, substantially as and for the purposes above described.

4. The combination of the two working joints or couplingsr D and R with the dischargepipe N and supply-pipe A, by means of which both the horizontal and vertical motions are and for the purposes specified.

In witness whereof I have hereunto set my hand and seal.
