UNITED STATESy PATENT OFFICE.
MOTT. R. BROOKS, OE OAK POINT, NEw YORK.
PORTABLE BARREL PUMP.
SPECIFICATION forming part of Letters Patent No. 523,757, dated J'uly 31, 1894.
Application filed April 16,1894.
lowing isl a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, and to the letters of reference marked thereon.
The present invention has reference to that class of portable force pumps for which al patent was granted to me the 3d day of January,
1893, No. 489,367, and is designed as an improvenient thereon whereby a more perfect action of the pump is secured in allowing the liquid to liow in and out of the pump freely and without obstruction and preventing it from overflowing at the top of the casing, and the usual rubber or leather valves and packing and also stulhng-boxes are wholly dispensed with.
The invention consists 1n a pump constructed substantially as shown in the draw'- ing and hereinafter described and claimed.
In the accompanying drawing which represents a sectional elevation of my iniproved pump, A designates the outer cylinder and B the inner short cylinder at the lower end thereof, the two'being connected together in any suitable manner. To the lower end of these cylinders is a valve-seat a and an opening b through which the liquid passes into the cylinder, said opening being controlled by a suitable valve c.' A movable pump-cylinder C is located within the outer cylinder A, and near its lower end has a diaphragm d with a central opening c and a valve f to control the same.
To the upper end of the pump-cylinder C is a cap g and suitable handle D for operating said cylinder, and extending de wn centrally into the cylinder is a tube E which communicates at its upper end with a passage which in turn communicates with a nozzle t. A spiral spring F is located between the two valves c f, the ends of said spring bearing re- 5e spectively against the 'valve-seat a and the Serial No. 507,694. (No modelli diaphragm d which serves to force the cylinder C back after its downward stroke.
A cap la fits over the upperend of the cylinder A and forms a tight joint between the cap and the pump-cylinder C.
Near the upper' end of 4the outer cylinder `A are a suitable number of air-vents Z so that liquid being pumped, the openings being labove the top of the short cylinder, the cyl'- inder A will retain, while in action, sucient of the liquid to prevent air from passing or being sucked in between the short cylinder B and the lower portion of the cylinder A.
The cylinder A has a circumferential apron G to act as .a shield for the openings m to prevent any obstruction floating in between the cylinders A B.
The cylinder A with the openings lm near its upper and lower ends respectively, is tlie essential feature of Inyinvent-ion, rendering as it does the perfect operation of the pump, which, without the openings would be less eifective in its action.
Having now fully described my invention, what I claim as new, andfdesire to secure by Letters Patent, is-f VA portable barrel-pump consisting of a movable inner cylinder and a stationary outer cylinder, a short cylinder upon the lower inner end of the outer cylinder, and openings near the top and lower ends of the outer cylinder', and a circumferential apron' to act as a shield for the openings near the lower end of the outer cylinder, substantially as and for the purpose set forth. ,t
In testimony that I claim the above I have hereunto subscribed my namein the presence
