JAMES C. LAMB AND ERWIN LAVENS, OF MIDDLETOWN, CONNECTICUT,
' ASSIGNORS TO W. 85 B. DOUGLAS, OF SAME PLACE.
IMPRQVEMENT IN RQ'TARV PUMPS.
Specification forming part of Letters Patent No. 1341,294l, dated December 24, 1872.
To all whom it may concern:
Be it known that we, JAMES C. LAMB and ERWIN LAVENS, both of Middletown, in the county of Middlesex and State of Connecticut, have invented an Improvement in Rotary Pumps, of which the following is a specification:
This invention is designed as an improvement upon the rotary pump described in Letters Patent No. 102,136, issued to us April 19, 1870; and the improvement consists in the arrangement of the abutment roller or rollers within the discharge-chamber for operation in combination with one or more revolving cams and, furthermore, when two or more such cams and abutment-rollers are used in the arrange ment within said discharge-chamber, of a dividing plate or plates for the separate retention of said rollers, but such divided chamber communicating with a common outlet. By this improvement a continuous stream may be obtained under a very simple construction of parts, and a pump be produced which is both durable and efficient.
In the accompanying drawing, which forms part of this specification, Figure 1 represents a sectional view, in direction of the length of the operatingshaft, of a rotary pump constructed in accordance with our improvement; and Fig. 2 is a sectional view of the same, transversely to said shaft, at the line ac as in Fig. 1.
Like letters refer to like parts in both figarcs of the drawing.
A is the supply pipe or inlet for the fluid, and B the cylinder of the pump, provided with a channel, 0, and aperture 1) for establishing communication between the inlet and the cylinder. D D are cams or eccentrics attached to a cross drivin g shaft, E, and constructed to operate in varying contact with the cylinder for the purpose, as the shaft E is revolved, of drawing in the fluid and expelling it from the cylinder. These cams or eccentrics are set to occupy opposite or diii'crent positions on. the
shaft E, and are separated one from the other by a dividing-plate, d. G is the box or chamber in which the movable abutment, or, rather, abutments, consisting of rollers H H, are arranged, said rollers resting on the cams, and operating to insure the action of the latter as pistons in like manner to that described for the pump previously patented to us, as hereinbefore referred to. But in the present construction the box G is constructed with a dividingplate, g, between the rollers, and in line with the dividing-plate d between the cams. It, however, has a common outlet, I, which may be in the removable cover J of the box, and which is in free communication with the di vided chambers of the box.
Any greater number than two revolving cams or'eceentrics, having dividing-plates between them, for operation by the same shaft, and a corresponding number of rollers and dividing-plates within the discharge-box, may be used, if desired.
The effect of theimprovement-is to produce a continuous stream without materially increasing the number of separate parts over or as compared with a pump having a single cam or eccentric and single loose roller, and which latter combination does not produce a continuous stream.
\Vhat is here claimed, and desired to be secured by Letters Patent, is-- 1.. The arrangement of the abutment-roller H within the discharge-chamber G, for operation in combination with the cams D and cylinder B, as herein shown and described.
2. One or more dividing-plates, g, within the discharge-chamber G, having a common outlet, I, in combination with the abutmentrollers H H and cams D D, all arranged substantially as specified. I
