HAND-PUMTP.
Specification of Letters Patent.
Patented Mar. 1, 1910.
Application filed August 28, 1908. Serial No. 450,755.
" drains, and similar places. It is ivell known ,that pipes of this nature often become clogged with material which collects sometimes gradually and forms a stoppage which make the connected sink, water-closet, or other article overflow, thus doing a good deal of damage and causing considerable annoyancc.
The object of my invention is to produce a very simple and inexpensive form of pump which can be easily applied to the sink, closet, or other receptacle connected with the pipe which is stopped, and by which sufiicient hydraulic force can be applied to the stopped pipe to cause the clogging material to be ejected.
My invention is intended to furnish a pump which can be easily applied to such places, which can be conveniently operated by hand, and which will enable suflicie'ht pressure to be created for the intended purose.
Reference is to be had to the accompanying drawings forming'a part of this specification, in which similar reference characters indicate corresponding parts in all the views.
Figure 1 is a broken view partly in section and partly in longitudinal section, showing m y improved pump. Fig. 2 is a view on a reduced scale, showing the application of the pump to a sink drain. Fig. 3 is a cross sec- .tion on the line 33 of Fig. 1. Fig. at isa broken sectional plank on the line 4-4 of Fig. 1, and Fig. 5 is a lcross section on the hne 5-5 of Fig. 1.
The pump has the usual barrel 10, piston 11, piston rod 12, and handle 13, these parts being substantially like the ordinary hand air pump, but the construction of said parts can be varied indefinitely, as these features I do notfclaim in detail. The essential thing is to have a porn barrel with a reciprocating piston therein. he barrel 10 is off-set at the lower end as shown at. 1-1, and for convenience this off-set part can be a' separate piece from the barrel, but this is not essential. Below the off-set portion 14 the barrel is reduced as'sliown at 15, and is provided with an external flange 16 below which is a nozzle portion 17 which can be provided with a washer 18 so as to take up the space between the nozzle and the outlet of the sink or other receptacle in, which the pump is used. Obviously the only necessary thing is to get a reasonably tight connection between the nozzle part 17 and the pipe in which it is inserted, and any suitable washer or a wrapping of elo'th, waste, or other material can be used forthe purpose. The lower end of the pump has also an internal flange 19 which serves as a seat for the check valve 20 which is arranged below the seat, and is normally closed by the spring 21 which is arranged between the cross-bar 22 and the head 23 of the guide post 24: which is se cured to the back of the valve. The object of the valve 20 is to permit water to be forced downward into the pipe, but to prevent it from coming back, and while I have shown a valve suitablefor this purpose, it will of course be understood "that any suitable check valve can be used/instead of that illustrated.
Through the oil-set 14: is a water in-take 25 which delivers into an inner cylinder or bori26, this having side ports 27 dischar ing into the lower part ofthe pum barre l. In the box 26 is a valve 28 preferab y a ball valve, which rises above "the-ports 27 when water is sucked into the box and barrel, and which is prevented from rising too high by the cross-bar 29. I find this check valve and-box best suited-for the purpose intended, but as, stated with regard to the valve 20, I do not limit the invention to the use of any particular valve. It is necessary, however, to have the opposed valves 28 and 20, and to provide the intake below the water line in the receptacle in which the pump is used, so that when the water comes into the barrel 10 the valve 28 is opened and the valve 20 closed, but when the water is expelled, the valve 20 opens and the valve 28 closes. The
.off-set at the lower end of the pump barrel pump barrel to be readily inserted in the the pump is used, the lower end of the barrel is inserted in the pipe to be cleared, a suitable packing being placed around the pump nozz'ieso as-to make a reasonably tight joint, sufiicient water is placed in the receptacle above the pipe to fill the pipe and extend above the opening 25,-and then the pump is worked precisely as usual with hand pumps. It will be seen that at every down pressure of the pistonflvater will be forced past thevalve 20, while at the up stroke of the piston the water cannot come back, and so hydraulic pressure will be created below the valve 20 which, as is well understood, canbe made considerably heavy, and this pressure is-sufiicient to ordinarily remove matter which has clogged the pipe.
It will be'seen that- I have provided a very simple, easily operated and easily applied pump, which is well adapted to the purposes referred to; v
Having thus fully described my invention, I claim as new and desire to secure by "Letters Patent outwardly opening valve in said nozzle, and
an inwardly opening valve in the under-. side of said laterally extending portion.
2. A pump comprising a barrel, a plunger operative therein, an extension mounted upon the lower end of said barrel, said extension first bent. laterally, then downwardly and inwardly, the end 0t said extension contracted to form a nozzle, an outlet valve in said nozzle, and an inlet valve in the underside of said laterallybcnt portion in proximity to said noazle.
