PUMP.

SPECIFICATION forming part of Letters Patent No. 303,339, dated August l2, 1884:.

Application filed November 14, 1883. (No model.)

10 all whom, it may concern.-

Be it known that I, Monnrs D. TEMPLE, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pumps; and I hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention re lates to make and use the same, reference being had to the accompanying` drawings, forming a part of this specification.

The object of my invention is, first, to construct a pump with a' body or barrel of wood, and with a bucket chamber or cylinder made of glass, hard rubber, metal, or enameled metal, and to unite said parts in such a manner that the value of the iinished structure cannot be in any wayinjured by the shrinking or by the swelling of the wooden part, and, second, to apply the same construction to iron pumps,

thereby making a better article and at the same time save much labor in the construction ofthe same. This construction of apump with an internal cylinder attains three specitic ends, Viz: First, when the pump-barrel is made of wood, it provides a means ofiirmly securing the cylinder thereto in such amanner that the Wooden pump-barrel may shrink Without injury to itself or the cylinder, and may swell without loosening` the cylinder from its position; second, the mechanism which secures such internal cylinder firmly in place also forms a seat for a checkwalve, iu corr nection with which any known form ol checkvalve may be used; third, this construction is equally applicable to iron pumps, whereby a porcelain or like cylinder for a bucketchamber may be fastened within the pump, being more desirable for the bucket to work in and more easilyrand cheaply made and applied than it is to bore out the rough casting.

Metallic cylinders have been applied to Wooden pulnps hitherto either by driving the cylinder into the bore of the pump-barrel or by driving the pump into the cylinder. In both cases the cylinders 'were held by friotional contact and lateral pressure. When a metallic cylinder was driven into the bore of a pump, when the wood was not thoroughly seasoned and the pump remained in store a length of time before being used in a well, the wood was cracked, split, and ruined by shrinking against the unyielding cylinder, or if the cylinder was made of glass, it was broken, being unable to resist thepressure of the shrinking wood. On th'e other hand, if the wooden barrel of a pump was thoroughly dry at the time, a metallic cylinder was inserted, when put to use in a well and saturated with water, it swelled, enlarging the bore. The cylinder consequently became loose, the water escaped, air was admitted, the suction impaired or destroyed, and the, pump rendered useless.V

Agaiii, when wooden pumps were driven into metallic cylinders obversely, similar diiculties were encountered. By the shrinking of the wood the cylinders became loose and dropped ofi", by the swelling ot the wood the cylinders were cracked unless made very strong and heavy and much more costly than in my construction, in which all said difficulties, arising from dissimilar natural properties of the material used, are entirely overcome.

In the drawings, Figure l represents a vertical central sectional elevation of the part-s of a pump in which my improvements are made. Fig. 2 represents the ring h, cross-bar o, and bolt and nut connecting thesame. Fig. 3 is a plan view of o of Figs. l and 2.

Like letters refer to like parts.

In the drawings, A represents a pump-barrel provided with an interior iiange, b, at asufiicient distance from the lower end thereof to permit driving the end ofthe stock C securely into its place without disturbing the flange b or its attached parts, preferably leaving some free space, as shown. Above the flange I), and within the barrel A,is placed a cylinder, D, of glass, hard rubber, porcelain, metal, or enameled metal, provided with a dange, c, which rests upon a packing-ring, f,which bears upon the angeb. Upon the angecis placed apaekingrin g, g. Through the cylinder D is passed a metallic ring, h, provided with arms t', leaving Water-Ways between them. Attached to the arms i is a bolt or stem, j. Said ringhhas an exterior iiange, 7c, which rests upon the packingring g, placed upon the fiange c. The cylinder D is free from the barrelA and the ring h from the flange b, a sufiicient space being left to permit the barrel A to shrink without coming into lateral contact with the metallic parts. To prevent the water from ruiming back through the said free space around the cylinder. D and the ring h is the office of the packing-ringf. Likewisethe packing-ring g prevents the escape of water between the fianges lc and e. The bolt or stem 7' passes through an opening in the cross-bar o,is threaded, and provided with the nut t.

Vhen all the parts mentioned are placed in their several positions, the cylinder is rm- 1y clamped to the fiange b by tightening the nut t against the cross-bars 0, which bears against the under side of the fiange b,- and it is obvious that said parts may be taken out of the pump-barrel for repair or renewal at any time by removing the nut t.

It will be observed that the ring 71 with its flange k, stem j, and nut t, together with the cross-bar o, form a mechanism by which the cylinder` D is secured to the p ump-barrel A by vertical longitudinal pressure on the fiange b, which forms an integral part of the pumpbarrel A.

It will also be observed that the pressure on the flange b is against the ends of the grain or fibers of the wood in the only direction inA which the wood will not shrink or swell, and also that there is no lateral Contact between the wood and inet-allie parts. rlhe upper edge or face Z of the ring h forms a valve-seat for the check-valve m.

The distinguishing feature of .my invention is an internal fiange within the ends of the pump-barrel, having shoulders upon both its upper and under sides, to which an internal cylinder may be attached, pointing in either direction.

I am aware that pumps with internal shoulders have heretofore been made on which internal cylinders with flanges have been placed; but I do not claim such constructions.

What I claim isl. A pump barrel provided between the ends of its bore with an internal flange, in combination with an internal cylinder attached to said iiange at one of its ends, substantially as specified.

2. A pump-barrel provided with internal fiange within the ends of' its bore, in combination with an internal fianged cylinder and a check-valve seat, all within each other, and mechanism to unite said parts,substantially as specified.

8. In combination with a pump-barrel having internal fiange between the ends of its bore and an internally-fianged internal cylinder, a flanged ring, all within each other, and mechanism to unite said parts, all being free from lateral contact, substantially as specified.

4C.A In combination with an internally-flanged pump-barrel and internally-hanged cylinder, a fianged ring provided with water-ways, arms, and astem, and mechanism to unite said parts, substantially as specified.

5. The combination, with a pump -barrel provided with an internal flange between the ends of its bore and internal flanged cylinder and flanged ring attached thereto, ofthe packing between said flanges, substantially as specified.

6. In combination with a pump-barrel, A, provided with an internal flange, b, a cylinder, D, provided with flange c, and a ring, h, having valve-seat and flange k, arms z', stem j, cross-bar o, and nut t, substantially as specified.

7. AA pump-barrel, A, provided with fiange b, and cylinder D, with flange e, in combination with ring 7L, with valve-seat l, and flange k, having arms fi, stem j, cross-bar o, nut t, valve m, and packing f and g, substantially as specified.

8. A pump-barrel provided with internal flange within the ends of its bore, in combination with a flanged cylinder and mechanism for uniting said flanges, substantially as specified. A
