I HENRY DUKE of 1 Jersey Street Bootle in the County of Lancaster Ship-
smith do hereby declare the nature of this invention to be as follows:-
--
The invention relates mainly to reels and chains for carrying and giving motion
to the chains and buckets or pistons of chain pumps and the object is to so make
such pumps that the chains and buckets will wear longer than heretofore without
renewal.
The first part consists in constructing the reels with cross bars or spindles carried
in bearings movable radially by means of screw or other suitable devices. By this
construction as the links of the chains lengthen by wear and strain the bars or spindles
may be moved further apart so that the chains and buckets will correctly fit the reel.
Second. In connecting the links of the chains to each other and to the buckets or
pistons by means of bushes and pins; the bushes are of comparatively soft material
so that the greatest wear will take place in the said bushes which are renewed from
time to time.
Third. In making the links between the buckets or pistons adjustable that they
may be shortened by means of screw and nut or like devices.

smith do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:-
The invention relates mainly to reels and chains for carrying and giving motion to
the chains and buckets or pistons of chain pumps :-and the object is to make
such pumps that the chains and buckets will wear longer than heretofore without
renewal.
The first part consists in constructing the reels with cross bars or spindles carried
in bearings movable radially by means of screw or other suitable devices.-By
this construction as the links of the chains lengthen by wear and strain the bars
or spindles may be moved further apart, so that the chains and buckets will correctly
fit the reel.
Second In connecting the links of the chains to each other and to the buckets
or pistons by means of bushes and pins, the bushes are of comparatively soft

Third-In making the links between the buckets or pistons adjustable that
they may be shortened by means of screw and nut or like devices.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation of a chain pump reel constructed in accordance with my
invention The reel consists of two frames a secured the requisite distance apart
on the shaft b, c. are bearings carried in slots d. in the frames a, e. cover plates to
slots d. held in position by set screws f. g. screwed stems attached to the bearings c.
and passing through the cover plates e, h. nuts, i. cross bars or spindles extending from
frame to frame and held in position by the bearings c, j. chains and buckets or pistons-
The bearings c. fit stiffly in the slots d, and are drawn further from the center of the
frame by the nuts h.-As the links of the chains wear and the buckets or pistons
become further apart.-Many forms of mechanism may be used for moving the
bearings c. in the slots.-Instead of sliding in slots the bearings might have apertures
therethrough and be carried on rods spokes or guides.
Figures 2 and 3 are sectional views at right angles to each other of chain pump
links constructed in accordance with the first part of my invention, k. links, l. bushes
of soft metal, m. pins, n. pistons or buckets. As the bushes wear they are withdrawn
and fresh ones substituted.
Figure 4 is an elevation of chain pump links made adjustable by being attached to
the buckets or pistons n. by means of washers o. and screws p.

page_text: Figure 5 is an elevation of a modification of apparatus in which the links are con-
nected to each other by means of right and left handed screw couplings p. so as to
allow of the distance apart of the buckets or pistons being adjusted.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, I declare that what I claim is:-
First. Reels for chain pumps having cross bars or spindles adjustable radially by
means of screw or suitable devices.
Second. Constructing links of chain pumps with bushes substantially in the manner
and for the purpose set forth.
Third. Making the links connecting the buckets or pistons of chain pumps
adjustable substantially in the manner and for the purpose set forth.
Fourth. The combination with the buckets or pistons of chain pumps of bushed
links, for the purpose set forth.
Fifth. The combination with the buckets or pistons of chain pumps of adjustable
links for the purpose set forth.
