ROTARY PUMP.
Specification of Letters Patent.
Patented Dec. 7, 1920.
Application filed June 4, 1918. Serial No. 301,867.
useful Improvements in- Rotary Pumps, of
which the following is a specification.
The invention has for an object to effect improvements in devices used as rotary pumps or rotary internal combustion engines, and has for an' object to simplify the casing construction of such devices and minimize the number of parts, and machine operations required in the production of such device, without impairing the efiiciency of engines of this type. It is a specific aim of the invention to improve the construction of sliding abutment for engines of this character.
Additional objects, advantages and features of invention may appear from the construction, arrangement, and combination of parts hereinafter set forth and shown in the drawings, representing one of the possible embodiments of the invention, wherein,
Figure 1 is a vertical sectional view of an engine constructed in accordance with my invention, taken through the major medial plane thereof,
Fig. 2 is a sectional view at right angles to Fig. 1.
Fig; 3 is a top view of the motor.
There is illustrated an engine comprising a casing 10, which may be cast and fitted to be secured upon a su port as at 11, the casing having a circular c amber 12 therein, having a cylindrical peripheral wall smoothly machined to an accurate form, the casing being closed on either sideb'y head plates 13 and 14 respeptively, the latter having a. bearin '15,,tliere1n in which there is slidable a she t 16 one and set in a socket bearing 17 in the'p ate 13. An oil oup 18 is mounted on gl he Plate 13 in a suitable manner, from which duct extends to'the bearing 17 as indiiotod in Fig. 2. A proper gland 19 is fupon the bearing 15, compressing a p against the shaft,16., A fly or I piilleyiwheel' 20 is mountedupon'thc. outer endof'the shaft 16. The shaft-.16 is concentric with the chamber 12, and has splined tl ii:re(j nv it piston 21, circular in form-but counted eccentrically upon the shaft, so that t .will bear against the inner wall of the chamber 12, at the: line of bearing a wear possible size.
around, the mutually adjacent ends of the bars being overlapped and suitably mortised. Inwardly of the bars there are confined suit able springs 28 by which they are forced outwardly against the sides of the passage 25.
At the inner end of the abutment, a suitable groove 29 is formed thereacross, having a partly circular form in cross section, and snugly revoluble therein, there is a wiper bar conforming to the shape of the groove, and having aflat side bearing against the piston. This bar and the groove are set closely adjacent one side of the abutment in the direction of rotation of the piston, when used as a pump and the end face of the abutment upon the opposite side is inclined outwardly and away from the piston, a passage 30 being formed through the abutment, which opens through this end face where it is sloped away from the piston. The passage mentioned is rectilinear in the outer part of the abutment, but is curved slightly toward thei inclined end face of the abutment at its inner '-part. It should be noted that the inclined end face of the abutment extends from the middle part ofthe abutment giving ample room for an opening therethrough of the lar est A shoulder is formed a jacent the inner part of said passage, upon which there is a spring 31, compressed by a suitable retaining pin or spider 32mounted upon the outer part of the extension 23 in a pro er manner. The extension 23 is formed wit an enlarged interiorly threaded recess 33 around the outer end of the passage 25. with which ipe connections may be made. If desired t e assage 25 may be closed at each side by suitable extensions 23' formed Through the extension andplates l3 and 14 by means of springs insertcd in the outer end of the grooves and bearing against the ends of the plates 34.
If desired, a drain cook 36 may be mounted in one of the side blades, as illustrated. An oil cup may also e installed upon the intake.
It will be seen that without the use of special valve devices, rotation of the piston will cause the entrance of water throu h the inlet as the piston passes, and the orcing of the liquid outwardly through the abutment when the )iston approaches the abutment, the device aving been found to function in a very smooth manner free of excessive jar and vibration. I
It will be appreciated that by reason of the fact that communication is formed through the abutment up to the moment that the wiping part of the piston passes the far side of the passage 25, it is permissible to restrict the sides of the casing so that there will be a much less difference between its diameter and the diameter of the piston should this be found advantageous. It will enable the construction of an engine with an abutment having a very limited range of reci procation, which might be desirable for hl h speed engines.
hat is claimed is:
In an a ,paratus of the cha cter described a casing aving a circular c rnber therein, and having a passage opening therefrom extending away from the perimeter of said chamber, aduot connection on the casing at the outer end of said passage, a cam piston revoluble in said chamber, an abutment slidable in saidextension having a passage longitudinally thereth rough with an oblique terminal inner art opening laterallytoward one side 0 said.chamb er at theinner end of said abutment, said abutment having a bearing ortion at the inner end on the side opposite the opening of said passage, formed with a channel transverse to the chamber and semi-cylindrical in cross section and a wear member revoluble therein enga ing the piston, the inner end face of the a utment adjacent the passage outlet be ing inclined outwardly from the middle of the abutment and having the passage opening therethrough close to the said bearing portion.
In testimony whereof I" have affixed my signntu re in presence of two witnesses.
