Description

UNITED STATES To aZZ whom it may concern.-

Be it known that I, BIRDSILL HOLLY, of Seneca Falls, in the county of Seneca and State of New York, have invented a new and Im- 'proved Pump; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this speciicatiOn, inwhich- Figure 1 is an elevation cal section.

Similar letters indicate l figures.

`A is the main portion of the pump-barrel, which is combined with the other parts of my improved pump, as represented in Fig. 2.

The short tube C, placed upon and inelosing a portion of the upper end of A, is cast in one piece with the nozzle K, within the flanges i t'. Projecting inward from the ends of C there is an annular chamber, a, surrounding the series of apertures b b in the sides of the pump-barrel, and communicating with the nozzle. The object of this arrangement is to enable the position of the nozzle to be readily changed from one side to the other, as circumstances may require. The lower end of the nozzle-ring C rests upon and is accurately ground to the upper side of the flange m. The upper portion, crewed to the upper and Fig. 2 a vertiike parts in both B, of the pump-barrel is s extremity of A, and fits accurately to the upper end of the nozzle-ring C, and consequently serves to confine the nozzle in any desired position. The fnlrum-arm p, to which Athe handle q is jointed, is cast in one piece with the upper part, B, of the pump-barrel.

The base D of the pump is of the form represented -in Fig. 2, and is screwed to the lower extrcmity'of A. Within the cup rising from D there is located the circular valve-plate E, from which descends the tube S, passing down through a hole in tlie center of D. t is a leather disk, placed upon the valve-plate E, the periphery of which is pressed down irmly thereon by the lower extremity 'of A, which makes a water-tight packing between the two. The valve n, that closes the aperture in the valveplate, is cut from the center of the leather disk t, and is suitably weighted with metal.

The lead induction-pipe J which descends from the pump into the well or cistern, is con- Specification forming part of Letters Patent No. 6,500, dated .lun

May 7, 1850.

IMPROVEMENT IN PUMPS.

e 5, 149; Reissue No. 16S. dated represented in Fig. 2, to wit: AThe end ofthe lead pipe is passed up through the hole in the center of the base D, and a iange is formed at its extremity by forcing a mandrel into it. The tube S, descending from the valve-plate E, is then inserted into the-open mouth of the' lead pipe, and after placing the leather disk t upon the valve-plate the pump-barrel A is screwed into the cup rising from the base D, which forces down the val the lead pipe at the same time that the largest portion of the tube S, near the valve-plate, is forced into the 'month ofthe pipe, and firmly presses it againsttle sides of the aperture in the base. The cup rising from the `base D, having a screw-thread cut upon its inner sides, the metallic disk E placed therein, which serves as a valve-seat, and in connection with the tube S, descending therefr in the bottom of the base, serves to connect the induction-pipe to the pump when thebarrel A is screwed to the basewithoutl soldering or the addition of anything exterior to the pump. This manner of combining the induction-pipe and valve-seat with the pump also enables the pump to be detached from repairs may be required u ton, or induction pipe, the base ofl the pump fr the cistern or well.

The respective p that I make us ed in Fig. 2.

The cap F has a series of top, and is screwed to the edge of a ringof leather, l, is inserted between F and G, the outer periphery of which is turned upward and bearsagainstthesidesofthe pumpbarrel. Consequently, as the piston is forced downward there will be no friction between its sidesjand the sides of the pump-barrel; but when thepistonis drawn upward the weight of water above` it will leather ring against the rel with suicient force without unfastening om the platform over arts of the piston-plunger eof in my pump are representperforations in ils ring G. The inner sides of the pump-barto prevent the loss of any water around the same.

H is a perforated tube, placed within the ring G, having a conical ilange projecting from its upper end, which fits into a seat on the upper edge of the inner periphery of G. As the pisnected to the base of thc'pump in the manner the tube H will rise into the cap F, allowing the water to pass through ve-plate uponthe-iiange of om through an aperture its base, whenever pon the valve, pisforce the edge of the 2 f les the perorations in its sides into the cap F, from which it will pass through the holes in the top of the same. The water will also force up the edge of thepackingring l, and pass upward around the sides of the ring G as it de-v scends. \Vhen the piston is drawn upward, the tube H will descend into its place and close the aperture in the ring G, and the pressure of water upon the packing-ring l will force its 'edge 'against the sides of the pump-barrel and secured in any desired position, substantially as herein represented and described.

2. The manner of connecting the inductionpipe J, the valve n, and its seat E, with the base D of the pump without the aid of rivets or solder, and in such a manner that when the I base of the pump has been securely fastened tov a platform the respective parts of the pump, as also the inductionpipe, can be combined with the base or detached therefrom without disturbing its fastenings, to wit: by means of the cup rising from the center of the base D, which has a screw cut in its inner periphery and a hole in the center of its bottom, through which hole the induction-pipe J is inserted and enlarged by a mandrel, the metallic disk E, placedwithin the said cup,with the tube S descending therefrom inserted into the upper end of the induction-pipe, the leather disk t, from the center of which the valve n is cnt, placed on the disk E, and the whole securely combined with each other by inserting the screw formed in the outer peripheryof the'lower end of the pumpbarrel within the screw-thread formed in the inner periphery of the. base-cup, and turning the pump-barrel until the lower end thereof forces the above enn merated parts into the position represented in Fig. 2.

The above specification of my improvements in pumps signed and witnessed ytliis'th day ot April, 1850.
