JOTHREM M. PHELPS, OF QUINGY, ILLINOIS,

HIS RIGHT TO LOUIS L. WARE,

ASSIGNOR OF ONE-HALF OF OF SAME PLACE.

IMPROVEMENT IN CHAIN-PUMP BUCKETS.

Specilication forming part of Letters Patent No. 185,350, dated December 12, 1876; application tiled October 13, 1876.

To all whom t may concer/n:

Be it known that I, Jo'rHREM M. PHELPs, of Quincy, in the county ofAdains and State ot' Illinois, have invented a new and'nseful Improvement in Chain -Pump Buckets, of which the following is a specification, reference being had to the accompanying drawings.

The invention relates to an improved chainpump bucket; and consists in the devices substantially as hereinafter more fully described.

Figure 1 is a side view of a device embodying the elements of the invention. Fig. 2 is a central vertical longitudinal section of' saine. Fig. 3 is a side elevation ofthe device F, and Fig. 4 is a central section of the dome A..

In the accompanying drawings, A represents a cap, provided with the loop t at its upper part, which loop, at its base, is united with a plate, b, the edges ot' which are turned down, and from the center of which projects the standard d, threaded throughout its entire length. Upon this standard is placed the rubber dome B, which may be of any tlexible material, and is ot' the form of a trunhaving near its apex the recess e, which receives the cap or plate b, and secures it in a water-tight manner upon the dome, leaving` the parts thereof adjacent the edge of the plate tlush therewith. In the base ofthe dome is provided the conical aperture f,.

which, in the present instance, is faced with a piece ot' metal ot' correspondingdimensions. Ihe base ot the dome is cut away for a certain space Within its periphery, forming about the aperture j' an annular raised rim or shoulder, l), whereon is placed the washer E, provided at its center with the aperture h, through which extends the upper part ot' the cenet' upon the upper surface ot the plane l, below which is provided the loop 01 swivel m, while a threaded aperture extends directly through from the top of the cone i to the lower surface of the plate l. The plate, cone, and loop are preferably made in one piece, forming the device F. The cone z' is somewhat larger in dimensions than the interior of the aperture f.

Now, placed upon the standard d, with the washer E below, and the device F screwed up on the standard, that the cone z' will enter the aperture f, and in proportion as the device F is screwed up the standard. so will the flexible material about the aperture and the periphery ot' the base of the dome B be expanded. At the same time the washer E will be held in a water-tight manner against the dome by the pressure of the plate l, thereby preventing` the ingress ot' moisture, and also preventing the dome B from twisting when the cap A is turned.

It is plain from the above that the devices form a bucket having a exible center, the base ot' which can be expanded as desired to suit pipes of varying sizes, and which at the same time is protected against the ingress of water.

It is also clear that the metal lining of the aperture f may be dispensed with, if desired, and the cone act directly upon the rubber.

I am aware that chain-pump buckets have been made having conical apertures in the top or apex ot' dome-shaped centers; but such arrangements do not serve to expand the base of the dome, but only its sides. I do not, therefore, claim such construction; but

What I do claim as my invention, and desire to secure by Letters Patent, is-

1. The dome B, provided with the recess e, in combination with the cap A, having the plate D with its dependent edgcs,.as set forth.

2. The dome B, having the conical aperture fin its base, in combination with the Washer E, cone z', plate l, and threaded standard d, substantially as set forth.

In testimony that I claim the foregoing improvement in chain-pump buckets, as above described, I have hereunto set my hand this 6th day of October, 1876.

itis obvious that when the dome is
