JOHN SGHROEDER, OF DAVENPORT, IOWA.

'MO'I'OR.

Specification of Letters Patent.

Application filed April 3, 1908. Serial No. 424,954.

Patented Jan. 5, 1909.

To all whom it may concern:

Be 113 known that 1, JOHN SOHROEDER, a

citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented a new and ImprovedMotor, of which the following is a 'full clear, and exact description.

cember 10, 1907, wherein the actuating agent is'ordinarily Water, but may if desired be other motive fluids such as steam, air, etc.

The invention has for its purpose the provisionof a motor embodying in its construction an oscillatory cylinder provided with a working piston, and having valve-controlling means for alternately admitting and exhausting the motive fluid to and from the cylinder at opposite sides of the piston, the valve being referably actuated from the piston through the usual driving shaft by a segmental gear in mesh with a pinion fixed to the valve and provided with a radial arm through which a valve-rod is slidable, having stop collars.

The invention further contemplates the adoption ofcheck-valves at or near opposite ends of the cylinder for the admission of air when water is used as a motive agent, by which the exhaust of the water from the cylinder is easily effected, giving the motor a smooth regular motion and at the same time admitting of the closing of the valve earlier, and an economical use of the actuating fluid.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the preferred embodiment of my im roved motor as applied to a washing mac ine, the latter being shown partly in section; Fig. 2 is a plan of the construction shown in Fig. 1; Fig. 3 is a central vertical longitudinal section through the cylinder; Fig. 4 is a rear end elevationof the motor, showing the valve-rod in section; Fig. 5 is a vertical section through the controllin valve; Fig. 6 is a vertical section throug the valve, showing it in a different position from that shown in Fig. 3 and Fig. 7 is a perspective view of the valve.

I have shown the motor applied to a washing machine, in which relation it is especially adapted to be used, although I recognize that it can be employed satisfactorily for OWGI'IPUI'POSQS in general. The motor .em-

odies in its construction a base 10 preferably having edge flanges for strengthening purposes, offset at its forward end, and provided at its rear end with a vertical socket 11. In this socket is-adjustablysecured by suitable means, as a set-screw 12, a post 13 having its upper end bifurcated for receiving the projecting portion of a valve-casing 14 to which it is pivotally connected bya in or bolt '15. The valve-casing 14 is rigi with and forms the rear head of a cylinder 16 which has the usual working piston 17, the rod of which passes through the forward cylinder head 18 and the stuffing-box 19 secured thereto.

Leading into the valvecasing 14, referably at its top, is a supply pipe 20 whic. connects through ports 21 and 22 res ectively with the rear end of the cylinder and theforward end of the same atthe front of the piston, this last mentioned port, as best shown in Fig. 3, being formed not only in thevalvecasing 14 but also in the walls-of the cylinder and the inner face of the front cylinder head 18. At the intersection of the ports 21 and 22, a controlling-valve 23 is horizontally and revolubly mounted in the valve-casing, and is in "the nature of a conical plug cut away at its periphery for approximately a semi-circumference at the point of its length in a plane with the ports, as indicated at 24, and

is further out out at the opposite side to provide a slot 25 leading through its smaller end and discharging into an elbow 26 threaded to the valve-casing, and to an exhaust pipe 27. At the o posite side of the valve-casing the stem of the valve 23 asses through a stuffing-box 28 and throug a cup 29 envel- 0 ing said box, and is adjustab y secured t ereto by a screw 30. This on has an arm 31 rigid therewith and provide with. an off set portion through which is threaded a setscrew 32, which, in connection with a like screw 33 threaded through the elbow 26, serves to adjust the valve 23 in the casing with such exactness that the least ossible friction will be developed when a flui -tight joint is secured.

The end or cover of the cup 29 is extended at its lower side, in which is carried a pin 34, providing a bearing fora segmental gear 35, the latter being in mesh with a pinion 36 fixed to the stem of the valve 23. The segmental gear 35 has a radial arm at its opposite side, through which is slidable a valve- 41 is fixed to the driving shaft in mesh with a gear 42 fixed to a driven shaft 43, which in turn carries a fly-wheel 44. Also fixed to the driving shaft is a crank 45 having the usual pin on which the piston rod 17* is jour 1 naled. This pin also serves to operatively connect a rack 46 through a connecting rod 47, the rack having a pin 48 projecting from its rear face for this purpose. The rack is slidably supported in suitable ways carried by the base, the walls of which are extended to provide bearings for a vertical shaft 49 extending into the tub, as shown in Fig. 1,

where it is constructed with the usual agitating arms. These arms are revolved back and forth from the rack by a pinion 50 in mesh therewith and secured to the shaft 49. At or near each end of the cylinder is a check-valve 51, which is set to open as a suction is created in the cylinder at the opposite sides of the piston when the latter is reciprocated.

In the operation of the motor, assuming the parts to be in the position illustrated in Fig. 3, the water or other actuating fluid under pressure passes from the supply pipe into the valve-casing, and is enforced by the controlling-valve to pass through the port 22 to the front of the piston. As the piston travels rearwardly a quantity of air is taken in through the forward checkvalve, and the fluid at the rear of the piston is expelled through the port 21 and exhaust slot of the valve into the exhaust pipe 27. When the piston approaches the limit of its back stroke,

the forward collar on the valve-rod strikes the radial arm of the segmental gear, and by it and the intermeshing pinion, revolves the valve to the position shown in Fig. 6, thus cutting off the motive fluid from the port 22 and placing the same in communication with the exhaust slot of the valve and simultaneously connecting the supply pipe with the ort 21. The piston as it travels forward likewise draws in a quantity of air through the rear check-valve, which I have found to be an important factor in the smooth and regular running of the motor, and to also enable the cut-off of the water supply to take place earlier, that is, before the completion of the stroke of the piston, which obviously economizes the actuating fluid employed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. The combination of a base having a socket, a post adjustable in the socket, acylinder having a working piston, a valve-casing pivotally supported on the post, forming the head of the cylinder and rigidly connected therewith, a valve for controlling the admission and exhaust of the motive agent to and from the cylinder, and means operated by the piston for actuating the valve.

2. The combination of a base, a post vertically adjustable on the base, a cylinder pivotally supported on the post and having a working piston, a valve controlling the admission and exhaust of the motive agent to and from the cylinder, and means for actuating the valve from the piston.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN SOHROEDER.
