Specification of Letters Patent.
Patented May 18, 1905;.
To all whom it may concern:
Be it known that I, LOUIS L. PRATT, a citizen of the'United States, residing at Philaactual moving working parts, thereby eliminating the friction between these parts in all cases, whether the pump is used as a wet vacuum pum to and for all em 'loyed.
of which purposes it may be base and body member comprising a -uinp cylinder and having suction and disc .arge connections and suction and discharge chambers, a rotary drum and a movable means following the periphery of the drum and adapted to form a partition between the said suction and discharge chambers; and in my improved pump I may also employ means for forming a liquid seal between the surface oi the bore of the cylinder and the adjacent portion of the revoluble drum, all of which will be hereinafter more particularly described.
In the drawing, Figure 1 is aside elevation of my improved pump. Fig. 2 is a front elevation of the same. Fig. 3 is a vcrticalsection taken through the center of the suction connection and Fig. 4 is a divided section, the right hand portion of which is taken on the line y, 7/, Fig; 3, while the left hand portion thereof is taken on line a, r, Fig. 3.
Referring particularly to the drawing, 10
- designates a base connected to which and made integral therewith, is the body of the pump comprising a cylinder 11, a suction connection 12, a discharge connection 13, a suction chamber 14 and a discharge chamber 15. Secured to the u per portion of the :body member and inc osing the discharge chamber 15 is a cover 1.6. Between the suction chamber 14 and discharge chamber 15 there is a horizontally disposed wall 17 preferably provided with a series of discharge ports 18 normally closed by aseries of discharge valves 19, which maybe of any door a blower, or a compressor,
11 carrying out my invention, I provide a [sired type and which as illustrated are f mounted on a valve-rod e passing through the sides 21 and 22 of the pump and secured I in position by means of the nuts 0 or otherwise, and communication is provided for between the suction chamber 14 and the interior of the cylinder 11 by means of a pussage 2-0.
23 designates a shaft which at one end is journaled in a bearing a provided therefor in the side member 22 of the pump; the side member 21 being rovided with a packing gland I) through w ich the shaft 23 passes, ,and the opposite end of this shaft is journaled in a bearing 0 provided therefor in a bracket d which is suitably connected to and supported from the side member 21 of the Interiorlyof the cylinder 11 a drum 2 3: mounted eccentrically on the shaft 23 and is secured in position thereon by a suitable key 1 or otherwise. This drum 24 is ireforably closed at its ends and is partially hollow, having cavities 25 therein which are so constructed that when the drum is placed in position on the shaft it will be equallybalanced thereon. Centrally disposed between the cavities 25 in the drum 24, 1 preferably provide a p air of parallel walls 26 between 'u' rich there is formed a chamber 27 and running along the surface of the drum there is a slot 228 which communicates with the chamber 27. At each end of the drum 124 there is pro' vided- )referably in the sides of the pun]; an annular recess or space 29 to \vhiclii supply pipes 30 are connected. The annular space 29 is of such height as to communicate with the base of the chamber 27nnd by means of the supply pipes 30 the water or other liquid is conveyed to the annular space 29 to effect a liq uid seal at the end of the drum, the water or other liquid then p assing from the said sp ace to the chamber 127 and by the centrifugal action of the rotating drum 24. this water or other liquid is ejected through the slot 28. against the surface of the bore of the cylinder in order to provide a liquid seal between the same and the drum, between which as hereinbel'ore indicated, there is an appreciable clearance, that is to say, the radius of the bore of the cylinder is slightly greater than the. longest radius of the drum 24 which, as will be understood, passes through the slot .28. 31 designates an auxiliary shaft, one'ml of which is journaled in a bearing provided,
On the shaft 23 and .in alinernent 'withthe' crank arm 37 there is mounted an eccentric 38 provided with the customar eccentric stra s 39 on the exterior of which there is a has 40, and 41 is a head pivotally mounted on the free end of the crank-arm 37 and connecting the heads 40' 41 is a right and left clearance space member including a cylinder and suction longitudinal screw-threaded pin 42 connected in and to the said heads 4.0 and 41 and provided with the nuts 43, 44, and 45 as shown, whereby the distance between the heads 40 and 41 m2? be regulated or adjusted.
t will be understood that there is an appreciable clearance between the face f of the swinging partition and the adjacent surface of. the depending portion of the wall 17 and also that the nuts on the pin 42 are so adjusted that there is also a clearance between the face g of the swinging partition. and the adjacent surface of the drum 24, and that by means ofthe eccentric 38 and the connection therefrom through the head 40 41, the pin 42, crank-arm 37 and the auxiliary shaft 31, the swinging partition is caused to follow the eccentric movement of the drum so that this is constant at all points in the revolution e the drum; it being understood that I may employ means other than those hereinbeforefidescribed and shown in the drawings for accomplishing this purpose without departing from the nature and spirit of my inventionbi.
