OSCILLATORY WATER-MOTOR.

Specification of Letters Patent. 7 Patented J e 17, 1919:

Application filed December 5, 1916. Serial No. 135,197.

' in water motors of the oscillatory type. The

invention relates particularly to valve-mechanism for controlling the supply and exhaust of the fluid under pressure actuating the motor to the end that the latter may operate with the greatest degree of efliciency.

The main object of the invention is to providea. motor of the type set forth and valve- 7 mechanism thereforwhich provides for a free-flowing supply of fluid under, pressure to the motor, and an equally free discharge of fluid therefrom; and which is simple, efficient and cheap.

v The invention consists in the features of construction and combinations of parts hereinafter' fully described and claimed.

In the accompanyingdrawings illustrating the invention:

Figure -1 is .a fragmentary view in side elevation of the casing. of a motor equipped with valve mechanism embodying my invention, the said valve-mechanism beingshown in section, taken on the line 1--1 of Fig. 2.

Fig. +2 is an end elevation of the motor and valve mechanism therefor.

Fig. -3-' is a fragmentary detail section through the motor casing taken on the line of 2- The motor comprises the cylindrical casing 1, in the end walls of which the shaft 2 is journaled. Mounted within thesaid oasing 1 is a radially disposed partition member 3 which is provided with aradial slot in which an adjustable fin 4 is mounted; the latter abutting atone end against the shaft 2 and being adjusted to vary its position relativelythereto by means 'ofthe set-screw 5 engaging in a threaded opening in the circumferential wall of the housmg 1.

Mounted upon one end of the casing 1 is 2 a valve-housing 6 consisting ofatube which is provided between its ends with five equal annular enlarged portions providing an a11- nular chamber 7 and two pairs of annular chambers 8 and 9 respectively, surrounding the tube 10, which is mounted within said housing 6 and extends the entire length thereof. The said tube 10is provided with perforations or slots 11 whereby communication between the same and each of the chambers 7 to 9 is established. The portions of the tube 10 intermediate the perforated portions thereof and opposing the choked portions of the casing 6 are smooth and devo1d of openings.

The chamber 7 communicates with the supply pipe 12 connected with a suitable source of supply of water or other fluid under pressure, and each of the chambers 8 disposed on opposite sides of the chamber 7 is connected with the ports 13 disposed on opposite sides of and contiguous to the partition member 3 within the motor casing 1.

The outer or endmost chambers 9 of the casing 6 communicate with the waste or exhaust pipe 14 at different points between the ends thereof through connecting pipes 9.

Mounted to reciprocate within the tube 10 is a rod 15 which carries two pistons 17 and 16 which fit snugly within the bore of the tube 1.0 and are separated from each other a distance equal to thelength of two of the chambers 7 and 8, for example. The said rod 15 extends through a stufling box 18 in one end of the tube 10 and projects into a cylinder 19 mounted upon one end of the casing 6, and which is concentric therewith.

Withinsaid cylinder 19 said rod is provided with a piston 20 adapted to be fluid-pressure actuated to reciprocate said rod for disposing' said pistons 16 and 17 thereof alternately in the position shown in full lines, and the position shown in dotted lines in Fig. 1-, respectively. The rod 15 is further provided with two stop collars 21 for limiting its reciprocable movement.

Disposed parallel with and contiguous to the cylinder 19 is a cylinder 22 of smaller diameter communicating with the cylinder 19 through two ports 23 and 24 for admitting fluid under pressure to said cylinder 19 at opposite sides of the piston 20 therein. Said oylinder22 is provided with an inlet port 25 for fluid under pressure which is surrounded by an annular casin 26 connected with the supply pipe 27 w 'ch is connected with the supply pipe 12. A. reciprocab-le rod 28 is axially movable in said cylin der 22 and projects through the stuiiing box 29 at one end of the latter. The said rod carries two pistons 30 and 31 which are adapted to become positioned alternately, as shown in full and dotted lines respectively, in Fig. 1.

the other thereof with an exhaust port 33, both of which are connected with the waste or exhaust pipe 14. r

The shaft 2 carries a radially extending piston 34 provided with suitable packings for maintaining a fluid-tight joint between the same and the circumferential and end walls of thehousing-l. Externally of said housing the shaft 2 carries a segmental pro- ,jection35 which is adapted to engage the collar 36 on the rod, 28, and to alternately strikeopposite sides of said .collar for shlfting the pistons30 and 31 from one position throwing the pistons 30 and 31 to the positions shown in' dotted lines in Fig. 1. When the pistons 16, 17 and 20 are positioned,-as shown in full lines, water or other fluid from the pipe 12 enters the chamber 7,

a and passes through the tube 10 and perforations or openings 11 into the upper of the chambers 8, and thence into the port 13." At the same time the water .or other fluid contained'on the opposite side of the piston 3 1 within the casing 1 is being exhausted through the other of the ports 13, and passes intothe lower chamber 8, and through the tube 10 and-perforations 11 into the chamber 9, and thus into the exhaust pipe 1 1.

As the segment 35 strikes the collar 36'it moves the latter into contact with the endoi the-stufling box 29' and positions the pistofns 30 and 31, as shown in dotted lines in Fig.

1-. IVhen so positioned water or other fluid entering through the pipe 27 passes through the port 23 into the' cylinder 19, and moves the piston 20-to the position shown in dotted lines in Fig. 1-, thereby also positioning the pistons 16' and- 17, ,as

' show-n indotted lines.

from the pipe 12 now enters the chamber 7 and lower port 13 into the casing 1, thus reand passes thence into the lower chamber 8 versing' the direction ofqoscillation of the 7 piston 34 and causing thefiwater or other fluid previously admittedwto pass outthroughthe portof admission into the up- One end of the cylinder communicates with an exhaust port 32 and a The latter is,

Water or other fluid per chamber 8, and thence into the chamber 9 and into the exhaust pipe 14 through its connecting pipe 9 g 'The inlet andcxhaust pipes employed are preferably very large so that the f uid under pressure will be freely admitted with small loss by friction, and similarly freely exhausted'. The shifting of the piston-valves or slide val'vesis very quickly accomplished, it being important that the shifting of the valves occurs with too great, rapidity to permit of the motor becoming stalled by a positioning of. the several piston valves at points intermediate their limits of movement. The momentum of the piston is relied upon to-some extent to effect such rapid shiftingof thevalvesz.

. My said motor s particularly-adapted. to

actuating the oscillatory washing machines which are very* commonly. used in' households and laundries, particularly the for- ,mer, and it iswell-known thatthe weight of the clothes and the shifting ofthe samegin its container effects more or less unbalancing and variationin speed; of momentum of the rocking container therefor. This will aid in the satisfactoryloperation of the mo tor, as will be obvious.

While I have shown my invention inits preferred embodiment .itwill be understood, of course, that such construction maybe changed and varied as mechanical skill and adaptation may dictate without departing from the invention as defined in the appended claim. 7 i
