ROTARY PUMP.
Application filed February My invention relates to an improvement in a rotary pump, particularly pumps of that type in which a sliding abutment is used, and my general obj eet is to provide a simple and efiicient organization of pump parts substantially as hereinafter shown and described and more concisely set forth in the claim.
In the accompanying drawings, Fig. 1 is a longitudinal section of the pump on line.1-1
of Fig. 2, and Fig. 2 is a vertical section thereof on line 2-2 of Fig; 1. Fig. 3 is a side elevation of the pump. Fig. 4 is a side view of the drive shaft and rotor member. Fig. 5 is a side elevation and section on line 5-5 of Fig. 1. Fig. 6 is a perspective view of the sliding abutment. Fi g. 7 is a horizontal section of the pump on line 7-7 of Fig. 2. Fig. 8 is a sectional View of one of the side plates. Fig. 9 is a perspective View of the main body of the pump.
The pump comprises a main body A having flat sides 2 and a. spreading base 3. The central part of the body is circular and formed with a round opening which provides a work .ing space 4; for a rotary compression member B fixed to or forming an integral part of a drive shaft 5. This shaft is journaled in the hub portions of a pairof closure plates 6 and 7 respectively, which are adapted to be bolted detachably to the flat sides 2, using a thin gasket 8 to make a tight joint therebetween. The shaft opening 9 in side plate 6 is closed and sealed at its outer end by a plug 10. The other side plate 7 has a hollow extension 11 adapted to confine suitable packing 12 around shaft 5. A packing gland 14 and a nut 15 may be used to compress packing 12, and a pulley or gear may be afiixed to the exposed end of shaft 5 to drive the same and rotate compression member B at high speed.-
Member B comprises a round enlargement 16 having an endless rib or flange 17 encircling the same at a slant or obliquely to the axis of shaft 5. Flange 17 is of a diameter 45. to fit the circular wall of Working chamber 4,
and the oblique position of the flange places it in touch linearly with the inner'flat sides 18 of the enlarged hub portions 19-19 of closure plates 6 and 7, the engaging places being diametricall opposite each other on opposite sides of tiie chamber. Thus flange 17 divides the chamber obliquely into two separate segmental working spaces of graduated Width, and these working spaces are divided 13, 1925. Serial No. 8,912.
transversely by a sliding abutment in the form of a flat blade 20. The inner Wall of each closure plate is formed with a vertical slot 21 adapted to hold and guide blade 20 in its reeiprocable movement longitudinally of drive shaft 5. This movement is imparted by flange 17 in passing through a notch 23 in the bottomedge. of the blade. The blade extends through an inverted V-shaped space 24 iii-body A. and is held in place by a gib 25 having enlarged extremities 26 adapted to prevent longitudinal shift of the gib during reciprocatory movements of the blade. The flaring space 2 1 provides separate inlet and outlet ducts on opposite sideso'f blade- 20, and these ducts communicate with horizontal passages 27 and 28 which extend through screw-threaded bosses 29 to permit suit-able intake and discharge pipes to be connected thereto. The base ends of the horizontal passages are reduced in diameter and curved downwardly toward the inlet and outlet ducts. and a small channel 30 is formed transversely in one wall of slot 21 in each closure plate to permit the liquid to pass into upright pockets 31-31 opposite the ends of rec-iprocable blade 20. These pockets provide working room and equalizing pressure spaces for the blade, and the liquid displaced by the ends of the blades in entering these pockets escapes through the channels 30. The bottom edge 32 of blade 20 is curved to fit the round enlargement 16 of rotor member B, and the liquid is forced to flow continuously in one direction while the drive shaft is being rotated. Thus the oblique flange in one revolution will draw in a given amount of liquid on one side of the sliding abutment and discharge thesame on the other side,
and a uniform flow of liquid is maintained.
because the oblique flange provides two compression spaces of equal area and the same shape diametrically What I claim, is: A rotary pump, comprising a body having opposite each other.
around working chamber, a blade transversely slidable of said chamber, a rotary member having an annular rib engaging said blade and dividing said chamber obliquely into separate segmental spaces, and a gib {)or said blade removably connected to said Iii testimony whereof I aflix my signature.
