Description

or h owers, according as they are operated by y FRITZ-iiossnAcH-Rousse'r, or TEMELHQF, NEAR genus, GERMANY.

. To all whom it may concern:

Be it known that I`,\`\ FRITZ ROSSBACH- ROUSSET, a subject of the 'Emperor .of Germany, and a Vresident of .Tempelho, near Berlin, in the Empire of Germany, have in'- ve-nted certain new and useful Improvements in Rotary Engines and Pumps; of which the following is a specification. Q

My invention relates to rotary machines ada )ted for use either as engines or as pumps a driving fluid, suoli as steam, orby power from a motor. l fr,

The present invention has especial, reference to structures employing a plurality of pistons .rotating intermittently and connected sucessively with the shaft or other permanently. rotating part. In devices of this character, considerable ditliculty has been experienced in avoiding jerky motion and excessive temporary strains on the transmittingmechanism interposed between the 'pistons and the iermanently `rotating part. To overcome t iese defects, I have devised a novel arrangement and connection of elements, particularly of the transmitting mechanism, and-I will now describe a few" practical embodiments of my invention with reference to the accompanying drawings, in which Figure 1 is a longitudinal vertical section through one form of my invention; Fig. 2 is a cross section thereof on line A-B of Fig. 1; Fig.. 3 is a longitudinal section of another -form of the machine; Fig. 4 is a cross section thereof. on line C-D of Fig. 3; Fig. 5 is a longitudinal section of a third form of construction, Fig. 6 isa'crosssection on line E-F of Fig. 5. Figs. 7 and 8 are peispective views of the two pistons 3, 4, employed yin the construction illustrated by Figs. 1 and 2; and Figs. 9 and 10 are perspective views of the two pistons 3l?, 4b employed in the construction shown in Figs. 5 and 6.

' The stationary casing 1 of the machine is .provided with inlets 7 and outlets l() for the driving or propelled fluid. A shaft 2 is joui'- iialed air-tight in the center ofthe casing and on this shaft. are mounted loosely rotary pistons 3 and4. Each of the pistons 3, 4, is adapted to be held stationary at times between the ports 7 and 10, by means of a locking member or slide 9,V operated at the proper ni'oinent' by meansl of suitable mechanism such as a cam 17 mounted on the shaft 2 and a lever S controlled by said cam.

v `Applcation filed November 6, 1907. Seria] No. 401,016. i ll l I win which Fig. 2-,shows the Patented Aug. 4, isos.

So far as above described, the construction shown in Figs. land 2 need notditfer materially from usual ones, although the )istonsl 3, 4,' have certain novel features fu ly set forth hereinafter;

D sTATns ramena OFFICE. .y l,

The'well-known general operation ofl this i machine', when used as a motor, is as follows: In Fig. 2 t-he piston 4 is shown locked by the slide 9, and forms -an abutment for the steam or other medium admitted at 7. The iston V3 being loose, is rotated in the direction of thearrow until it comes in contact with the stationary piston 4. Immediately before this, thel locking member 9 is withdrawn through the action of the cam 17 lor otherwise so that the impact of the piston 3 against theiistond throws the latter forward beyon 1\ the port 7, as indicated in dotted. lines, while at the saine time the piston 3 is locked by the slide 9 in the same position iston 4. The )istons therefore rotate a ternately and intermittently. To transmit this intermiti tent motion to a rotary member, for instance the shaft 2, in such a manner that it will rotate continuously and \\-'ithsubstantial uniformity of speed, I have provided the following improved mechanism: The two pistons 3, 4, which iref'erably overlap in the manner indicated in Fig. 1, have rigidly secured to their hubs 5 and` 6, bevel ear wheels `12 and 13 respectively, co-axia with the shaft 2. The latter is provided with a rigid hub 514 carrying radial studs 15 on which are mounted to turn bevel pinions 11 each of which permanently engages both bevel gear wheels 12 and 13. `The details of construction may, of course, be varied. Ori the` shaft 2 mav be mounted a pulley 16 to receive or de iver iower, as the case may be. The operation of this transmitting mechanism will be understood readily. If for instance the piston 4 is stationary and the piston '3 in motion (see Fig. 2) the rotating bevel gear wheel 12 ill not only turn the bevel pinions 11 about their axes or studs 15, but owing to the engagement of said pinions with the stationary bevel gear wheel 13 the pinions 11 will roll on said stationary wheel and thus move bodilytogether with the studs 15, hub 14 and shaft 2, in the same direction In accordetary gearing, the rotary speed of the shaft 2 willv be one-half of that of the piston 3. IVhen this piston colli'des with the piston 4 and Gear wheel `13, while the gear wheel 12 (released at that moment by the withdrawal of the locking member 9), both pistons and" the shaft move in unison for a short interval, that. is, until the slide 9v locks the pist-on. During-'this interval the momentum of the shaft and of the heavy parts connected there?. with, causes the two pistons and the shaft,

to iotate ;at .practically one-half the piston speed. Then the steam or other medium will exert a driving action on thepiston 4 might break the teeth of the gear wheels, it-

being noted that the pinions 1l are in mesh )ermanently with the gear wheels 12 and 13. 'nstead of bevel gearing, I might employ spur gears. The motor is reversible by simply altering the fluid connections so that 1() will become the inlet and 7 the outlet.

In Figs. 3 and 4 the casing-1 has two diametrically opposite inlets 7 and two outlets l()a between each pair of which is located aflocking member 9u for the four pistons 3, 4, the tivo lockingmeinbers being operated similarly in unison by cam mechanism (not shown) which may be of the same character as the one shown in Fig. 1 at 17, 8. Each vof the four pistons is mounted loosely on the shaft 2". The shaft 2a in this case has two hubs 14a ivithradial studs 15a for pinions 11a. Each of the .pistons 3a has rividly secured to ita gear wheel 12a, and eac i of the pistons 4, a gear wheel 13a. Each of the pinions 11 meshes with one of the ear wheels 12 and with tlieadjacent gear iv ieel 13a. The operation-is very similar to that described above, it being understood that the pistons of the same pair (3a or 4) are lockedand released at the same time by the slides or locking members 9a.

The construction illustrated by Figs.

and 6 'has the planetary gearing arranged outside the casing 1*. One of the overlap ing pistons 3b, 4b, is rigidly secured by its nib 5" to ythe shaft 2b, the out-her (4b) has vas mounte its sleeve-like hub 6* extended considerably to the outside of the casing and provided with a gear Wheel 13b. This piston 4b is loosely on the shaft 2". To the latter is secured rigidly lthe gear wheel `12", and between the two wheels 12b and 13b I mount on the shaft loosely', the hub 14" of the pulley 16b carrying the radial studs or spokes 15b on which are mounted the pinv ions 11b, each in mesh with the Wheels 12b and 13b. The operation will be practically the same as above described, it being understood that the arrangement of fluid inlet .12, causing the and fluid outlet,4 and of members for alternately locking and releasing the pistons, is

the samein principle as in the other forms of 'my invention. v

'Ifyinstead of admitting a driving medium `through the inlet, power is applied tothe pulley or equivalentl partjthe alternate rotation of pistons thus produced,.iyill createsuction at. one port and pressure at the other, so t'liatthe machine will in that case operate as a' pump or blower.
