his invention relates to certain improvements in lifting-pumps, and consists in the peculiar means employed for allowing, when necessary, the waste or surplus water to escape from the cylinder.

yTo enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A, represents the pump cylinder which may be constructed of cast metal and of suitable dimensions. On the upper end of this cylinder, a bowl or dish-sha ed fianch B is screwed, one side of which as a spout C. The Hauch Bis also constructed of cast metal. On the upper end of the cylinder A, an lu right pro'ection (a) is formed, through t e upper en of which the fulcrum pin (b1) of the handle D passes. The projection (a) is cast with the cylinder A.

The lower end of the cylinder A, is secured by bolts (b) (b) to a hollow base E, which is also constructed of cast metal. At the center ofthe top of the base E, a screw (c) is secured, and the top of the base, around the screw (c), is perforated with holes (d), as seen in Fig. 1, and also in dotted lines in Fig.

2. These holes (d) are covered by a circular iece of leather (e), which has a projecting ap (f) at one art of it. This flap (f) has two holes (1) (2li made through it, and a pin (3), attached to the top of the base, is fitted in either of these holes, When the pin (3) is fitted in hole (l) a passage (4) is exposed, said passa eY leading into the suction flanch or socket g); and when the pin (3) is fitted in the hole (2) the orifice of said passage (4) is closed. This will be understood'by referring to Fig. 2, in which the flap (f), as shown in black, covers the orifice of passage (4), but exposes it when in the position as shown in re On the upper surface of the leather (e), an annular chamber (h) is placed, the screw (c) passing through the center. The inner and outer edges of this chamber rest or bear snugly on the leather (e), as shown clearly in Fig. 1. This chamber (7L) has a projecting flanch (i) formed" on it, said fianch being also provided with two holes through either of which the pin (3) asses.

On the screw c) a circular plate (j) is screwed. This plate is perforated with holes (7c) and its outer part is curved, corresponding to the form of the upper surface of the chamber (h) see Fig. 1. n

The flanch or socket (g), at the under side of the top plate of the'base E, is cast with the base. This flanch or socket (g) is of conical form as shown clearly in Fig. 1. And the upper end of the suction or eduction pipe F is fitted over the flanch or socket (g), the orifice of pipe F being made of Haring or bellshape to correspond with the form of the ianch or socket. The pipe F is as usual constructed of lead, and a brass or iron tube G is fitted over the upper end of the lead pipe F; the upper end of the tube G being made of bell-form 4corresponding to the upper end of pipe F.

H, represents acast metal bar having a conical o ening made through it to allow the pipe and tube G to pass through. And through the ends of the bar I-I, the bolts (b) (b) pass; said bolts have each two nuts (l) (m) on them; the nuts (l) secure the cylinder A to the base E, and the nuts (m), when screwed u tightly against the under side of the bar cause the conical opening in said bar to bind the upper end of the ipe F snugly around the socket (g). The base E is secured by screws to a pro er platform I.

J, represents the piston w ich is secured to the rod K, the upper end of which rod is attached to the handle D. The piston is formed of two parts (n) (o), both of which are constructed of metal, and the part (n) is a circular plate of slightly concave 0r dish form and perforated with holes (p) near its edge or periphery, as shown in Figs. 1 and 4. The edge of the plate (n) is bent upward, as shown in Fig. 1. The other part (o) of the piston is formed of a ring connected by arms (1') to a circular plate s), through the i l NN Mw center of which the piston rod K passes. The lower end of the piston rod has a screwthread formed on it, and the plate or part (n) -is screwed thereon. L, re resents an annular piece of leather, iitted etween the outer part of the late (n) and the ring (o), and iirmly secure between them by screwing up the plate (n) suificiently on the lower end of the rod yK. The outer part of the leather ring L is bent upward and forms the packing of the pistonf The inner end of the leather extends beyondand consequently covers the holes (p)1in the plate (n) .and forms the valve ol the piston.

The operationol' the pump-that is, the lifting andv discharging o' the water-revquires no description, as it is precisely the same as that of all simple lifting-pumps.

By adjusting the leatherA (e) so thaty the` passage (4) is exposed, the wasteorsurplus water is allowed to escape from the cylinder' A, into the suction pipe F, and the pump cannot be frozen up Aduring the winter. In summer, the leather isv so adjusted as to4 cover the passage (4) so that the packing of the valve may not shrink. The chamber (7L) serves as a protection to the leather (e) and prevents the edges of the leather from being forced through the holes (d) by atmospheric pressure above as the water descends in pipe F and produces a vacuum therein. The chamber (h) effectually prevents this.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-

The leather (e) placed over the perforations (d) in the top of the base E, and the chamber (h) which is placed on the leather; said leather being provided witha flanch(f) provided with holes (l) (2), either of which is fitted on the pin (3), for the purpose of exposing or closing the passage (4), substantially asdescribed for the purpose specified.

BIRDSILL HOLLY.
