To all whom it may concern:
Be it lmown that I, JOHN SHARP, en ineer, a subject of the King of Great Britain and Ireland, and a resident of Glasgow, Scotland,
have invented certain new and useful Improvements in Rotary Gas Exhausters, of which the following is a specification.
This inventidn relates more particularly to improvements in rotary gas-exhausters;- but the improvements are also applicable to pumps and engines.
The main object of mg invention is to increase the efliciency of t e exhauster, pump,
or engine b means of the additional gas-pasble to rotary pumps or rotary engines,
shown in Fig. 1.
as taken on the line 8 8 of Fig. 1.
sages, whic insure the complete chargin of the-pumping-chamber at each stroke, w la the maximum amount of fluid is pumped at each cycle of operations.
In the accompanying drawings, Figure 1 represents a longitudinal sectional elevation of a rotary exhauster as constructed in accordance with my improvements. Fig.2 is a sectional lan view as taken on the line 2 2 of Fig. 3. Fig. 3 is a vertical section as taken on the line 3 3 of Fig. 1. Fig. 4 is an end elevation of the exhauster with the drivin end cover removed. Fi 5 is anoutside e evation of the outer en cover of the exhauster Fig. 6 is a section taken on the line 6'6 of Fig. 1. Fi 7 is an end view of the outer end cover wlth the additional inlet and outlet ports and connecting-pipes to the main inlet and outlet ipes and valves. Fig. 8 is a vertical section oFouter end cover Fig. 9 is a longitudinal outside elevation corresponding to Fig. 1, showing the outer covers at both ends, in which the inlet and outlet passages are formed; and Fig: 10 is a detached enlarged transverse section of the revolving blades and eyes.
Although my improvements are ap licafi W1 in the following, specification describe them as applied to a gas-exhauster.
A represents a hollow cylindricalcasing having a central stationary'shaft L there,- in. On this shaft I mount a series of ref..- erably three) radial arms or blades at spaced distances apart, the blades being mounted on the shaft by their hubs L. A hol low drum or barrel I is mounted eccentrically within the outer casing, and where the blades E pass through therevolving barrel I to the circumference of the outer cas' the barrel is fitted with logig slotted cylin 'cal Specification of Letters Patent. v Application filed March 10, 1205- Serial No. 249,425.
. passage tongue pieces or rollers N to form rocking joints, so as to be automatically adjustable to suit the varying relative angles of the blades E during each rotation. The inner Patented Feb. 13, 1906.
barrel I has a' central driving-shaft J, so that when the barrel I revolves the blades E, mounted on the inner stationary shaft L, are carried around with it. Connecting with the outer casing A 'are the inlet and outlet passages C and C. The gases pass through a port G into the outer casing A and discharge through the port 0 on the'opposite side. In addition to this the gases are also conducted from the inlet side throu h a ort on the end cover into the interior%) of the inner barrel I and are discharged through another port, preferably diametrically opposite to this, or other suitable equivalent, and by thesermeans a volume equal to the part denoted by D, Fig. 10, of the inner barrel and a volume substantially e ual to one-half the space between the inner )arrel and the outer casing are discharged three times per revolumay be discharged in one end cover, or one inlet and outlet may be formed in each end cover. g
' Referring. particularly to my present improvements, cast in the main-casing an additional as-inlet passage A and an outletleading toward each end to the corresponding inlet and outlet passa es. a and b, respectively, in the end covers B, and said passages would communicate direct with the main inlet and outlet branches or orts O C, the object being to increase the ee flow of gas toward the chambers or passages A and B in the end covers A B, leading to and from the inner chamber D of the revolving barrel I (seen particularly in Fig. 10) and so increasing the pum in efiiciency, due to the portions of the bla es acting 1n the inner chamber D. By a modified arrangement, as shown in Fig. 7, the additional inlet and outlet passages may be formed by connecting the .main inlet and outlet passages C O to the passages ab in the endcovers A B by the inlet and outlet pipes F F and valves Gf In the case of the valves G G being connected as described the said communicating pipes F F would be connected in such aposltion that when the inlet and outlet valves were shut off these pipes would also be cut off. These improvementsv would IIO be applicable for the purpose of conducting gas to bothendsof the exhauster and inner In order to secure an inletassage of gas at both ends of working-barre I, the usuallyclosed or driving end Willhave placed on it an arrangement, of ports h h, Fig. 2, suitable for communicating with correspondin ports H H in the end cover A. T s is carried into practice by removing the usual closed end of the .barrel 1 and replacing it with preferably a cast-steel end I, on which is also formed the main driving-shaft J of barrel, and the necessary ports. h h referred 'to are cast thereon. This casting would be made large enough-to embrace the three correspondin segmental ends ofthe revolving barrel, an each of which segments would be fixed by se arate bolts or ins K, Fig. 1, which woul artially'act as rivers.
The revolving blades E where they are attached to their respective eyes L would be strengthened at the junction by recessing a portion l l of the eye at each side, so that correspondingly larger fillets can be adopted, while by cutting a portion N of the oscillating slotted roller N opposite the connection of blade E with the eye L on the side of slot 0 posite the driving-face that portion of b ade E joining the eye may be correspondingly increased and strengthened accordingly. The portion of surface-of eyes L to be recessed from Z to l, and therefore not necessarily machined, is limited by the relative position of the inner ed es of two adjacent blades when the angle etween them is the minimum at or during every revolution, as
shown at X in Fi 10. The remaining portions of eye from to Z are machined 1n the usual manner, so as to maintain a comparatively-fluid-tight working fit between said eyesand' the corresponding or inner working ed es of the revolving blades.
claim as my invention I 1. A rotary exhauster, or the like, comprising an outer casing, a revolving barrel therein, blades in said barrel, and inlet and outlet passages to said casin in combination with covers at opposite en s of said casing, both said end covers having passages therein 0 ening to the interior of the barrel, and hot inlet and outlet passages communicating with both end cover passages.
2. A rotary exhauster, or the like, comprising an outer casin a'revolving barrel with blades therein, and inlet and outlet passages to said casing, in combination with end covers for said casing, passages therein with ports, corresponding ports in the driving end of the barrel, both of said end covers communicating with both inlet and outlet passages. 3. Arotary exhauster, or the like, comprising an outer casing, a revolving barrel with blades therein and having longitudinallyslotted rollers in its circumference, said blades passing through said rollers and having recessed portions on the eyes thereof, in combination with inlet and outlet passages to said casing and revolving barrel.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
