JOHN B. ROOT, OF PORT CHESTER, NEW YORK.

PUMP.

SPECIFICATION forming part of Letters Patent No. 280,402, dated July 3, 1883.

Application filed October l1, 1882. (No model.)

To (all whom it may concern:

Be it knownthat I, JOHN B. Roo'r, of Port Chester, in the county of Westchester and State of New York, have invented a certain new and useful Improvement in Pumps, that is fully and clearly described bylthe following specification, and illustrated in the accompanying drawing.

The object of my invention is the production of a cheap, effective, and durable handpump; and it consists in certain improvements in the float and valves of that class of pumps which employ a float or displacer attached to the pump-rod for the purpose of preserving the flow of the water during the downstroke, and by its buoyancy to eflject or assist in effecting the upstroke.

'In the drawing accompanying this description the figure is a central longitudinal section of a pump embodying my improvements. A is the barrel of the pump, constructed preferably of sheet metal, and provided with a shelf, a, for the support of the plug 0, which carries the induction-valves c,- and B is the float, which in this case is a hollow cylinder constituting the pump-rod, as the pump-handle D and the collapsing bucket b are attached directly thereto.

Attached to the plug 0 is a rod, F, on which the float slides during its strokes. A head on V the upper end of this rod and a bushing in the lower end of the cylindrical chamber B prevent the plunger l'rom rising too high when the pump is being operated; and these connections between the float and the valves render access to the valves for the purpose of removing clogging material or repairing broken parts an easy matter, as the float can at any time be lifted entirely out of the pinup-barrel, and with it the plug 0, with the inductionvalves.

G is a head fitted in the end the pumpbarrel, which serves to keep theibarrel. closed against the upward dash of the water as the float descends, and also as a guide and support for the upper end of the floai which always projects beyond this head. i

In the use of such a pump the energy of the workman is applied in the most economical manner and entirely in one direction, it being only required of him that he throw his weight upon the handle D and depress the float, for the upstroke may be entirely effected by the buoyancy of the float.

Pumps of this class are subjected to the hardest usage and used for a great variety of purposes, so that great simplicity and strength of construction, together with lightness, are essential considerations. These features of improvement I have secured in my construction by making the parts mainly of sheet metal and by so combining the parts that access can be had to any of them without the necessity of loosening connections. The most essential feature of improvement, however, consist-s in extending the float beyond the end of the pump-barrel. Ordinarily the bucket and handles and float are attached to a common rod, or the bucket and handles are attached to the float by separate rods; but by lengthening thefloat as l have described lT am enabled to attach the bucket and handles di rectly thereto and dispense with apu1np-rod,thefloat when thus used being much stronger than a pump-rod, and, having amore extended bearing in the barrelhead, can sustain a greater lateral strain.

Heretofore the float has been inelosed within the pump-barrel, and the barrel-head had first to be removed before the float could be wit]nlra\\'na necessity and inconvenience not incident to my form of pump; and, further, the float in my pump cannot be sunk below the surface of the water, thereby limiting its lilting capacity, as in the old form; but, however dceply it may be depressed, its liftingpower is always 1'n'oportioned to the depth of its stroke. i

Other forms of buckets maybe used in lieu of the collapsing bucket b, and the connecting-rod F might be rigid with the float and slide through the plug (1.

What is claimed as new is 1. The combination, in a pump, of the barrel A, provided with the head G, and a float, B, projecting from the pump-barrel, and provided with the handle D and bucket 6, substantially as shown, and for the purpose de scribed.

2. The combination, in a pump, of the barrel A, the float B, projecting from the barrel, the plug 0, provided with valves 0, and the connecting-rod F, substantially as shown, and

for the purpose indicated.
