IMPROVEMENT IN PUMPS.
Specification forming part of Letters Patent N o. l 75,246, dated March 28, 1876; application filed February 14, 1876.
To all whom it may con-cern:
Be it known that I, HENRY O. HART, of Adrian, in the countylof Lenawee and State of Michigan, have invented certain new and usef'ul Improvements in Pumps, of which the following` is a specification:
This improvement in pumps is .principally intended for the style of pump used in the saloons of railroad passenger-cars for pumping water from tanks, for either drinking or-Washing purposes. The invention consists of the followingdescribed attachment.
In the accompanying drawing, forming part of this specification, is shown a pump provided with the improvement hereinafter claimed.
The pump itself does not diEer `from wellknown forms of pum ps 5 but it is necessary for use in the saloons of railroad-cars that the pump vrod should pass through a stuflingbox to prevent the- Waste and scattering of water upon surrounding objects. The top of the pump, therefore,being closed air-tight, compression of air takes place above the plunger as it rises, the air not being able t0 escape fast enough, if at all, out of the spout or nozzle of the pump through the uprising column of water on top of the plunger, thus making the pump more diflicult to operate, which is frequently required to be operated by women and children having but little strength. The stream of water discharged by the pump is apt to be-unsteady also, or to be forced `out by alternato spurts, instead of -entirely on the outside; or
quietly and gently flowing out of the nozzle of the pump. -v
In order to obviate these objections the small pipe or tube A is fit-ted so that it shall lead from near the top of the pump under the stuffing-box down to some suitable point of discharge. By this simple expedient the air above the plunger ofthe pump can gently iniiow and outiiow as the plunger is operated, and all the difficulty above mentioned be avoided.
The pipe A inay lead fromthe -top of the pump downward on the inside, and then outward, as shown in the drawing, or said pipe may lead downward from the top of the pump it may be cast within the shell of the pump, having its upper and lower orifices suitably disposed-the one on the inside, the other on the outside, of
the pump.
Having thus ful y described this improvement in pumps, as of my invention, I claim- A tube leading from near the top of the pump under the stufng-box downward to a suitable place of discharge, substantially as shown and described.
In testimony that I claim the foregoing as my own I afx my signature in presence of two Witnesses.
HENRY O. HART.
