WATER-MOTORI Specification of Letters Patent. Application filed August 12, 1908.

Patented July 13, 1909.

Serial No. 448,122.

To all whom it may concern:

Be it known that I, Iinwis C. Lnwis, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Tater-Motors, of which the following is a specification.

My invention relates to water motors, and has for its object the provision of a device of this character constructed in such manner that it may be produced will yield a high degree of e'i'liciency.

A further object of the invention is the provision of means for water cushioning the l5 working parts of the motor to thereby render the device substantially noiseless in operation.

The motor forming the subject matter ol the present invention comprises iiarticularly a cylinder', a reciprocatory piston, a valve casing, a l'luid operated valve located within said valve casing, and a mechanically aei tuated valve located within the Afluid operated valve and entirely inclosed thereby,

the movement of the mechanically actuated valve serving to admit water to the valve easing Vfor the operation of the 'fluid actuated valve.

Further objects and advantages of the invention will be set Jforth in the detailed description which new follows.

In the accompanying drawings: Figure I i is a longitudinal vertical section of a motor i, constructed in accordance with the inven- "tion, Fig. 2 is a horizontal section thereof,

Fig. 3 is a plan view with the top of the valve casing removed, and, Fig. il is a transverse vertical section upon line of Fig. l.

Iiike numerals designate corresponding arts in all of the figures of the drawings.

Referring to the drawings, the numeral 5 lesignates a cylinder', one end of which is Ilosed by a cap 6. This cap is provided with L packing box of the usual and well known onstruction, through which a partially holl w piston rod 7 passes. This piston rod is clonnected to a piston 8 mounted to reciproclate within the cylinder 5. A valve casing 9 ist located at the opposite end of the cylinder from the packing box and comprises a cenat a low cost and l tral cylindrical portion l0, side walls Il, a

top plate 12 and a bottom plate 13. An inlet nipple I4 carried by the plate 13 is prel l erably threaded for the reception of pipe or hose couplings. An exhaust nipple 15 leads from the valve casing and is threaded in a like manner. A chamber I6 is formed between the cylindrical portion l() and the bottoni plate I3 and it is to this chamber that water passes from the nipple 1.4. Ports I7 lead from the chamber 16 to the interior of the cylindrical portion of the valve casing. A rib 1S divides that portion of the valve casing above the cylindrical portion inte two chambers I9 and 20. Ports 21 lead from the chamber 19 to the interior of the valve casing, while ports 22 lead vfrom chamber 2() to the interior of the valve casing. The chamber I9 is in communication through a port .23 with the left-hand end of the cylinder 5, while the chamber Z0 is in communication through ports 2d and 25 and by-pass 26 with the right-hand end of the cylinder.

A cap 27 closes the left-hand end of the cylindrical portion of the valve casingl and a cap 2S closes the right-hand end thereof, said latter cap carrying a packing box 29 through which a rod 30 passes. This rod carries a collar 31 which limits its movement toward the left in lfig. l. One end of this rod prol jects into the hollow piston rod and carries a l nut 32 which is slightly larger' in diameter' than the body of said rod. The piston has a flange 323 through which the rod 3%() passes, said vilange being adapted to eng-arge the cele lar 32 as the piston moves toward the right in lfig. 'i to shift said rod and the parts carried thereby, as will be hereinafter described. The inner end of the rod is threaded inte a tubular valve 34. This valve has a central port 35 formed in the wall thereof and carries outstanding llanges 3S. Cup leathers 36 and 37 are clamped between these 'flanges l and sleeves 3). Cup leathers il() and .l-l are clam )ed between these sleeves and nuts 42. lThe 1left-hand end of the tubular valve is open and at the right-hand end a port 413 is formed in the end of the rod 30. 'lhis structure 'forms the mechanically actuated valve hereinbefore referred to and is located within hand end of hausted thro the valve casing, would be ex- I ugh ports 57 which would at this time lie to the left of cup leather 40 by reason of the bodily shifting of the mechanically actuated valve, and through tube 44 and port 35. This exh cushions the iiuid operated valve and renders the operation oi'I the device substantially noiseless.

From the foregoing description, it rwill be seen that simple and elicient means are herein provided for accomplishing the objects of the invention, but while the elements shown and described are well adapted to serve the purposes -for which they are intended, it is to be understood that the invenmited to the exact construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

What I claim, is:

1. A device of the character described comprising a cylinder, a piston mounted in said cylinder, a valve casing mounted upon one end ofthe cylinder and comprising a central cylindrical portion, a pair of chambers outside of said cylindrical portion one of which is in communication with one end of the cylinder and the other of which is in communication with the other end of the cylinder, a mechanically actuated valve comprising a tube open throughout its length and having a pair of integral outstanding shoulders formed thereon, a abutting said shoulders, sleeves the inner ends of which abut said leathers, cup leathers abutting the outer end threaded upon the opp and abutting said last thereby bind all of said in which said mechanically actuated valve is slidably disposed, means for closing both ends of the last-named tube, four circumferj entially disposed packing members carried; by the last-named tube, the space between? the two central packing members forming an exhaust space, arod connected to the IneI chanically actuated valve and projecting intof the cylinder and means carried by the piston"I for engaging said valve. Y

2. A device of the character described comprising a cylinder, a piston mounted i said cylinder, a valve casing comprising' central cylindrical portion, a pair of cham bers outside of said cylindrical portion, on of which is in communication with one end of the cylinder and the other of which is i1 communication with the other end kof the cy inder, a mechanically actuated valve con uid actuated valve toward the right, the prising a tube open throughout its-length, water in the right-hand end of the valve casfour circumferentiallyy disposed packing ing is exhausted through ports 58, 43, 35 and members carried by said tube, the space be- 54. uring the movement ol'l the fluid actutween the two centralmcmbers forming an ated valve toward the left, water in the leitexhaust space, a tube in which said mea tube 44, the ends of which are closed by caps 45 and 46. A packing box 47 is carried by the cap 46 and iorms a fluid tight joint about the rod 30. rlhe sleeve 44 carries outstanding Hanges 47. Cup leathers 48 and 49 are clamped between these flanges and the sleeve 50. Cup leathers 51 and 52 are clamped against these sleeves by nuts 53 which are threaded upon the sleeve 44. Ports 54 are i'ormed in the sleeve 44 between the cup leathers 48 and 49. Ports 55 are iormed in the sleeve 44 between the cup leathers 48 and 51, while ports 56 are formed in the sleeve between the cup leathers 49 and 52.

The operation of the device is as follows: With the parts in the position illustrated in F ig. 1, Water from the inlet nipple 14 will flow through the right-hand port 17 to the interior of the valve casing and between the cup leathers 49 and 52. Passing through ports 22, chamber 20, ports 24 and 25 and by-pass 26 to the right-hand end of the cylinder, the piston having been shown at the completion of its stroke toward the left. During this movement of the piston toward the left, the water in the left-hand end of the cylinder was exhausted through ports 23, chamber 19 and ports 21 to the interior of the valve casing and into the space between the cup leathers 48 and 49. By referring to ig. 2, it will be seen that this space is always in communication with the exhaust nipple 15. During the movement of the pis-V ton to the left, the mechanically actuated valve was shifted to the left by the contact ol the piston with the collar 31. Wlater will now How through the left-hand port 17, ports 55 and ports 57 to the left-hand end of the valve casing and will exert sufficient pressure against the fl uid operated valve to force it to the right until the gland of the packing box 47 contacts with the cap 28. This will bring orts 21 into communication with the space etween the cup leathers 48 and 51 and will bring the ports 22 into communication with the exhaust space between the cup leathers 48 and 49. TWater flowing through the leithand ports 17 will now pass around between th 8 and 51 and o 21 into chamber 19, thence thro tothe left-hand end oi' cylinder' 5, driving the piston toward the right. At the same time the water in the right-hand end oi' the piston will be exhausted through by-pass 26, ports 25 and 24, chamber 2() and ports 22 to the exhaust spac 48 and 49 and t nipple 15. During the movement of the named cup leathers to parts together, a tube aust water effectually 7 s of said sleeves, nuts osite ends of sald tube chanicaily actuated valve is slidabiy dismeans carried by the piston for engaging said posed, means for closing,l both ends of the last Valve. named tube7 four circum `erentiaily disposed packing members carried by the last named 5 tube the space between the two central packlng members forming an exhaust space, a rod connected to the mec hanicaiiy actuated Valve and projecting into thc cylinder, and
