' HYDRAULIC TnANsmIss-ioiv.

To all ev hom it my,mmit.-.-

Be it known that ,1, Louis J. Hueons, a

citizen 'of. the United States, residing at Topeka, in the county of Shawnee and State of.Kansas, have invented new and useful Improvements in Hydrauhc Transmlssion,

of which the followingis a'specification.

This invention relates to tI'HJlSl'l'llSSlOIl means particularly adapted for automobiles for transmitting the motion of the drive shaft to the-driven shaft. 4

The principal object of the invention is to provide means for entrapping a substantially w'edgeeshaped body of fluid between the driving member and the driven member so that the motion of the said driving member will be imparted to the driven member Another object of'the invention is to pro.

vide lmeansfor' controlling the escape of fluid from betWeen said members so as to impart different speeds to the driven memher while the driving member is actuating other features of construet ion'and' in the drawings wherein like characters denote like or corresponding parts throughout the several views, a-nd'in wh1chz- Figure 1 is a longitudinal sectional view openings 16 m the walls of the cyllnder,

. of the invention.

Fig. 2 is a cross section on line 2-2-of Fig. 1.

Fig.3 is a section on line 3-3 of Fig. 1.

Fig. 4 is a section on line 4-4 of Fig. 1.

Fig. 5 is a view of the sliding sleeve or controlling member.

Fig. 6 is a detail view.

In these views 1 lndic ates' the easing which is formed of two parts connected to gether by the bolts 2. The ends of this casing are provided with thebosses 3, through one of which passes the driving shaftt and through the other the driven shaft5. This driving shaft, within the casing, carries the abutments 6 and the driven shaft'5 has secured thereto, or formed therewith, the cylinder. 7 which incloses said abutment-s.

'seen the rin f Specificationof Letters iatent. Patented NOV, 15, 1921, V Application filed December 20; 1919. Seria1 No.346, 255..-

Theend of this cylinder is closed by the cover 8" which is provided with the central opening 9 to receive the shaft 4; The end of shaft 4 fits within a-recess 10 formed within the shaft 5 at the point of junction withsaid shaft. It will thus be seen" that the shaft formed with its abutments may have rotary members 1'3 bridge the chambers formed by sa d eccentrics 11 and each. ring member is provided with an opening 1 1 through which one ofthe abutments passes. Thus as the shaft and abutments rotate the ring members 13 will be rotated with them. As will-be members 13 are in contact with a part of t e-cylinder so that as theabutments reach this point of the cylinder, said abutments will have their ends flush with the walls of the ring members or in other words said abutments'will be entirelywithin said ring members. 4 Upon the continued rotation of the parts the abutments will gradually project from the ring members and. sweep around the chambers and said abutments and ringmembers will divide the chambers into two parts which are entirely separated from each other as soon as the abutments pass out of the ring members.

I provide outlet openings 15 and inlet chambers and being .located adjacent the points of contact of the ring members with the cylinder.

rated from the outlet'openings by said ring members so that the fluid must pass around .the' ring members to get to the outlet open- The inlet openings. are sepaings.

In order to control these ports or openmgs I provide a sllde sleeve 17' which embraces the cylinder and is provided with

outlet ports

18 and 19 for coiiperati'ng with the outletports 15 of the cylinder and with an elongated inlet port 20 for cooperating with the inlet ports 16 of said cylinder.

This sleeve is provided with a. pair of spaced flanges 21 ;which receive the rollers 22 carried by the ends of the yoke 23, the stem24 of this yoke passing through a suitable stuffing box in the end of the casing.

In this way the sleeve may be adjusted in position on the cylinder to control the passage of fluid through the ports.

It will be understood that the fluid in the casing is under pressure so that it will Pass into the cylinder when the ports are opened. The casing is provided with a pressure valve 25 and admin plug 26. Spring controlled pressure-rings 27 prevent leakage at the bosses.

When the ports are opened and the drive shaft is being rotated the fluid will pass into the cylinder through the inlet ports and will be carried around by the abutment to the opposite side of the cylinder where it will flow from the outlet ports. If the outlet ports are restricted or entirely closed by the sliding sleeve the body of fluid in front of the abutment will assume a substantially wedgeshape between the ring members 13 and the walls of the cylinder so that said cylinder will be caused to.rotate with the shaft and abutments. By adjusting the size of the outlet ports by the sliding sleeve various speeds may be given to the cylinder without changing the speed of the drive shaft. If the outlet ports are entirely closed the cylinder will be rotated at the same speed as the drive shaft and in order to prevent the heating of the fluid under the continuous pressure I provide means for locking the cylinder to the drive shaft when the two parts are to rotate asone. Such means consists of a slidable member 28 having an offset part 29 provided with a curved face and an inclined face. The curved face is adapted to engage with an eccentric 30 formed on the end of the shaftt and the inclined .face

is engaged by the inclined end of a longi-- tudinallymovable lever 31 .which has its upper end provided with a neck 32 which engages a slot 33 formed in the sleeve 17. The part of the sleeve in which the slot 33 is formed is inclined so that as the slide is 1 28 and 31 are held 1n position against the end of thecylinder by the ring 34:. When the curved face of member 28 is held in engagement with the eccentric on the shaft the cylinder is locked'to the shaft and the two parts are rotated as one.

In order to reverse the rotation of the cylinder I provide an annular rack 35 on the cover 8 and a gear 36 on shaft 4 and a sliding gear 37, mounted on a pin 38, carrled by the casing, is adapted to mesh with said gear 36 of'the rack and in this way rotate the cylinder in the reverse direction.

This gear 37 is moved into and out of operative position by means of the rod 39 having its bent end engaging a groove e10 in the gear.

In this way the cylinder and its shaft may be rotated at various speeds by the drive shaft by the adjustment of the sliding sleeve 17 When the two parts are to be driven at the same speed they are locked together by moving the sliding sleeve to its inner position and when the automobile is to be reversed the rod 39 is moved to bring the gear 37 into mesh with the gear 36 and rack 35.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall 1 within the scope of .the appended claims.
