Pump-Bucket.
0Ct.26,1875.V
UNITED STATES PATENT OEEIcE.
EUGENE J. DUNBAR, OF ROMUIlUS, MICHIGAN.
IMPROVEMENT IN PUMP-BUCKETS.
Specification forming part of Letters Patent No. 169,155, dated October 26, 1875; application filed September 11, 1875.
To all whom it may concern:
Be it known that I., EUGENE J. DUNBAR,
of Rom ulus, in the county of Wayne and State improved bucket for suction-pumps, which shall be so constructed as to iill the cavity of the pump-cylinder at each upward stroke, and to surely open at each downward stroke.
The invention consists in the bucket made of india-rubber, 'in -cylindrical form, with a bell-shaped cavity in its lower end, and with longitudinal holes through it, the iron valve made in the shape of the frustum of a cone, and the iron rod provided withia stop-nut or collar,in combination with each other, as hereinafter fully described.
A is the body of the bucket, which is made of india-rubber, in cylindrical form, and with a rounded or conical upper endl In the lower end of thebucket A is formed a bell-shaped cavity, al, from which a number of holes, a2, lead up through the top of said bucket to form passages for the water. B is the valve, which is made in the shape of the frustum of a cone, and which is of such a size as to enter the bell-shaped cavity al of the bucket A, and expand the lower part of the said bucket, and cause it to ll the cavity of the pump-cylinder. The valve Bis made of iron, and into a screw-hole in its center is` screwed the lower end of an iron rod, C, which passes up through a hole through the center of the bucket A, and upon which is'formed, or to which is attached at alittle distance above the top of the bucket A, a nut or collar, c', for the upper end of' the said bucket A to strike against, to limit its upward movement upon the said rod c. The upper end ofthe rod C is screwed into, or
otherwise attached to, the pump-rod.
In using the pump, in making the downward stroke the valve B moves out ofthe cavity of the bucket A, and the said bucket `is then carried downward by the rod C, the water passing up through the holes a2 of the bucket A. In making the upward stroke the valve B is drawn up into the cavity al of the bucket A, expands its lower end -to lill the cavity of the pump-cylinder, and then carries it up with it.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The bucket A, made of india-rubber, in cylindrical'form, with a bell-shaped cavity, al, in its lower end, and with longitudinal holes a2 through it, the iron valve B, made in the shape of the frustum lof a cone, and the iro'n rod C, provided with a nut or collar, c', in combination with each other, substantially as herein shown and described.
