HYDRAULIC MOTOR.

Specification of Letters Patent.

Patented April 23, 1907.

Application filed May 29,1905- Serial No. 262,766.

To all whmn it may concern.-

Be it known that I, JAooB SOHAEFFER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Hydraulic Motors; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others, as well as those skilled in the art to which it appertains, to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this s ecification.

My invention relates to fiydraulic motors,-or that class of devices which is operated by means of the utilization or manipulation of Water as a motive power ;-and are so constructed as to be able to transmit said power in such a manner as to run or operate any small device or machine,but more especially washing machines,for which purose my improved motor is more especially designed and intended.

Some of the principal objects or purposes,and advantages of my invention;- consist in producing a water motor as above referred to, of simple construction; composed of few parts; inexpensive in cost of manufacture, and one which will work automatically and give more perfect results than heretofore obtained from other devices of a similar nature.

The invention consists of the very peculiar and novel arrangement, construction and combination of the various mechanical parts, as will be more fully referred to in detail hereinafter, and set forth in the subjoined claims in accordance with the statutes in such cases made and provided therefor.

In the annexed drawings constituting a formal part of this specification, and wherein the same letters of reference indicate the same parts wherever occurring throughout the several views :Figure 1, is a plan view of my hydraulic motor. 'Fig. 2, is an inverted plan view partially in section, of one of the movable valve-rods and its spring catch, and the boX or case inclosing same. Fig. 3, is an inverted plan view of the hookedend of one of the movable valve-rods, and its s ring-catch. Fig. 4, is a side elevation of t e motor. Fig. 5, is a side view partially in section of the two-way valve and stuffing boX. Fig. 6, is an end elevation of the motor. Fig. 7, is a broken away longitudinal sectional view of a portion of the cylinders; the head to said cylinders; and the two-way valve. Fig. 8, is a plan view of the movable valve rods, the flat spring for actuating them, and the inclosing casing; and Fig. 9, is a perspective view of a broken away portion of the vertical shaft, with the disk, short sleeve and sprocket-wheel held in position thereon by the retaining-pin.

In describing my said invention specifically, and referring in detail to the different parts or various mechanical elements or features of construction, which combined, make up my improved hydraulic motor, as shown throughout the various views of the drawings and indicated by means of the letters of reference as aforesaid, a, designates the twoway valve provided with the usual stufiingboX and retained in position in the forward cylinder head by an ordinary nut Z through which valve-stem 0 passes :said valve being shown in a position turned sufficiently so as to allow the water as forced from the city water main,or other suitable source of supply having suflicient pressure and conducted by means of a pipe or rubberhose connected to mouth-piece d see dotted lines in Fig. l;said water passing therethrough, and thence through the concavity or recess a formed in said valve, and along the channel or water way in the forward cylinderhead'see more particularly Fig. 7, also Figs. 1 and 5;into the cylinder C; when said water will strike the plunger or pistonhead f, forcing and moving it and its rodf backward and in the direction indicated by the arrows, until said cylinder has been filled by the water; and as said piston-rod thus moves backward it will carry with it sprocket-chain g, which is suitably hooked or detachably connected to the end of said piston-rod at h; and said chain thus moving will turn or rotate sprocket-wheel "i,see dotted lines Fig. 1, also Figs. 4 and 9;and with it the clothes-rubber or rubber-head K upon shaft Kupo n which said sprocketwheeli also is mounted by means of its short sleeve i and pin 11 as clearly shown in Figs. 4 and 9 ;it of course being obvious that in practice said rubber-head or its equivalent will rest in the washing-machine of any ordinary construction, whilst the entire motor is intended to be firmly and suitably supported on the washing-machine by means of base I: which is to be bolted or otherwise suitably connected thereto in any well known manner: said base being provided with a long sleeve i extending up to short sleeve 01 of sprocket-wheel i, and through which said vertical shaft passes and is held therein by means of retaining-pin i -passing through said short sleeve and vertical shaft-see Figs. 4 and 9. Secured at 9' to base I, are the flanges J which form the forward and rear ends or heads of the cylinders G and D, and.

hold said cylinders securely between the same by means of long-bolts 3' in an ordinary and well known manner, as shown: the rear flange J being formed with collars 9' through which the piston-rods move or play, and thus forming a support or bearing for same.

Firmly mounted upon valve-stem c is a cross-head k, to which is movably pivoted by means of their slotted ends I and Z the valve rods L and L said rods being slightly flattened and having a smooth surface where they cross and come in contact, and are provided with shoulders m,as clearly shown in Figs. 1, 2 and 8; whilst the opposite and rear end of said arms rest in a casing or boxing N, and have connected to them preferably by screw-threads, the hooked ends at and n, which as shown more particularly in detail in Figs. 2 and 3 are provided with spring catches 0 and 0 so formed at p and p as to be adapted to engage the sides of the boxing or casing, when said, movable rods are forced back to the rear as their springs g and q ,which are held between boxing N and the annular flanges or washers r and r on said movable rods,are compressed; as shown by spring g in Fig. 1, and will be more fully described hereinafter.

Now as just above described,the water passing into cylinder 0 will force piston-head f and piston-rod f 2 backward, thus causing sprocket-chain g to rotate sprocket-wheel 'L, and thus turn vertical-shaft K, and clothesrubber or rubber-head K also disk S which is formed integral with short sleeve 11 the same as sprocket-wheel t'see Fig. 9and is located at top of said vertical shaft, which will move in the direction indicated by the arrows,and which is provided with a small lug or in t,-which engages the hooked ends of sai movable valve-rods, each in their order; said disk being further provided with fingers a; and as the disk turns, the small lug or pin 25 will move out of its engagement with hooked end 11, thus releasing it, whilst finger u will be brou ht to bear against end p of spring catch 0 forcing said spring catch out of engagement with the boxing or casing N, which will now permit or allow spring g to react and expand, throwing movable valve-rod L forward, when its slotted end l which is movably connected to cross-head 7c'wi1l move said cross-head, thus turning or reciprocating the two-way valve a in the direction indicated by the arrows,and traveling back in the path it has just come,

but in an opposite direction from the position shown,see Fig. 7-(said valve always making a one quarter turn from mouth-piece d to one cylinder; and then reciprocating back again until it passes said mouth-piece, and makes another one quarter turn to the opposite cylinder;)the rods Lthus causing said valve to continue and complete the turn or reciprocal'movement, until recess e of said valve establishes communication with the opposite cylinder D ,which now in its turn fills with water: whilst straight edge 12 of valve (1 has now opened communication from cylinder C to the exhaust-port w. Now whilst valve a is in the position shown, and whilst cylinder 0 is filling with water as first above described, and the disk, sprocket chain, and wheel, and the shaft are being operated by reason of piston-head f and its rod f 2 being forced backward,as indicated by the arrows; through the pressure exerted by the water as it rushes into said cylinder; and as chain 9 has its opposite end hooked at k to piston-rod 8 it will now move said piston-rod and its piston-head 8 forward, until all the water has been forced out of the cylinder D, and along the channel or waterway of the cylinder-head, and straight edge 12 of valve a,see Figs. 5 and 7,through exhaust port to and out of waste pi e W.

In some cases it may be found a visable to use a flat spring for actuating the movable valve-arms, as shown in Fig. 8; instead of the coil springs shown in Figs. 1 and 4; or if a very heavy tension is required both the coil and flat sprin s may be employed together; or in fact any orm or style of member having sufficient resilience may be employed, although in practice I expect to employ the flat spring 9 It will of course be understood that in practice the cylinders will each have a suitable vent or air-opening to prevent them from becoming air-bound.

I wish to be clearly and positively understood, as reserving to myself the ri ht under the well known and long establishe doctrine of patent law, of making any minor changes in the arrangement, combination, or construction of the various parts of my device as may from time to time be suggested, all within the scope and spirit of the invention, and without departing from the principles of the same.

Having now fully and clearly described the construction and operation of my device what I claim as my invention is 1. In a water-motor, and in combination with the valve provided with a cross head; of the cylinders; the piston-heads and pistonrods, which have a reciprocal movement in said cylinders; the sprocket-chain and wheel actuated by the piston-rods; the movable valve rods connected to the cross-head of said ends of said piston-rods for transmitting with the spring-catch, the spring, and. the disk for actuating said valve-rods; all subl stantially as described.

2. The combination in a water-motor, of the two-way valve having the inlet and exhaust sides; the inlet pipe; the exhaustport; the cylinders and the piston-heads and pistonrods, which have a reciprocal movement in said cylinders; means connected at power; the cross-head at top of said valve; the rods connected to said cross-head for actuating said valve; and springs for impelling said rods, and devices for controlling and releasing same; all substantially as set forth and described.

3. In the herein referred to hydraulic motor, the combination of the two way valve; the cylinders adapted to receive water through the inlet pipe from the source of supply and exhaust said water; the pistonheads and piston-rods adapted to play in said cylinders; the rods for operating said valve; the springs and catches for operating said rods; the vertical shaft; the means mounted upon said shaft for setting and releasing said valve-rods, and for connecting said piston- 4. The combination in an hydraulic motor u of the following elements, to wit :a valve having an inlet and exhaust side; the plunger-heads, and the rods, each of which moves or plays in each of said cylinders; the spring actuated movable-rods for actuating said valve, each having a hooked-end, and provided with a catch; the vertical shaft; the sprocket-wheel and chain for said plungerheads and plunger-rods; the disk provided with the finger and lug for actuating the movable valve-rods; and the inlet pipe, exhaust port, and waste pipe; all substantially as described.

In testimony whereof, I have afiixed my signature, in presence of two witnesses:

FRANK HAUSOHILD, HUGO STEINER.
