The bucket-packing is shown as a modification, (see Fig. 8.) These placed around the inner cup, the projections projections engage in perforations B in the on the out flange of which enter perforations 5o bucket-packing B, and secure it in its position. in the packing and secure it there. The lower I 0 ends of the strap irons or shanks are passed through the perforations F in the inner cup, the lower lugs being presented so as to pass through the divergent notches in connection with said perforations. The strap-iron then receives a half-turn, which brings it into position when the outer cup is rightly presented for the said lugs to pass throughthe notches in connection with the perforations as the end of the shank-iron passes through the cup into its seat. The strap is then turned a quarter round, bringing it in position to attach to the rod and in the direction to bring the lower lugs in position presenting inward toward each other, when the upper lugs will present outward, as shown in Figs. 1 and 3. When the'end of the rod D, which may be wedge-shaped or not, as desired, is inserted between the strap-iro ns and brought home to its position, the straps are pressed apart at top, and are thus made to exert a leverage in connection with the clamping-lugs to tighten the corresponding cups and bucket-packing and insure a stiff tight joint, in which, as there is no movement, (as when elastic packing is used,) there can be no wear. On the other hand, where elastic packing is used between the cups, of necessity there must be movementand consequent friction and wear. The rabbeted bucket-packing provides a recess for the flange of the outer cup, so that it does not interfere with the friction-surface of the packing.

The parts of the modified form being the reverse of those just described, it is obvious that to cause the upper lugs, G, to exert a downward and the lower lugs, G, an upward pressure, the upper ends of the straps or shanks 0 must be drawn together instead of being forced apart; hence, to state it broadly, the shanks 0 must be forced and held in the direction in which their respective upper lugs project.

We are aware that in constructing pumpbuckets the two bottom disks, between whose peripheries the packing is secured, have been provided with coincident elongated slots, through which the respective members of the bifurcated extremity of the sucker-rod are passed. Each of these members (or shanks) is provided with an annular collar, which, when the parts are secured together, rests upon the upper surface of the upper disk, and a lateral enlargement at its lower extremity corresponding in shape to the elongated slots through the disks, and occupies a position transverse or at an angle to said slots. This is not, however, the equivalent of our invention. With this device, in order to secure a tight joint and prevent rattling and leakage,

a rubber packing must be interposed between the two disks, which isput under compression when the parts are secured together, and afterward exerts its force in holding the two disks apart and against the upper and lower enlargements of the shanks. It is well known that rubber retains its elasticity but a very short while when used for this purpose, and it is the object of our invention to do away with it entirely and still produce a perfectly tight joint between the parts. Again, by forming the body of the perforations through which the shanks pass cylindrical, and arranging the notches in the respective disks alternatelv, as described, the aperture through the bottom of the bucket, considered as a whole, is cylindrical, (see Fig. 7,) and is completely closed by the cylindrical portion of the shank.

We claim as our invention- 1. In a pump-bucket, the combination, with the packing and apair of disks having slots, of a pair of straps or shanks each having a pair of lugs located, respectively, above and below said disks, and projecting from opposite sides of its axis, one toward and the other from a line drawn through the axis of the bucket at right angles to a line drawn through the apertures, said shanks being forced in the direction in which their respective upper lugs project and held by bolts to the sucker-rod, as set forth.

2. In a pump-bucket,the combinatiomwith the packing and a pair of disks having keyhole slots F F, said disks being so arranged that the cylindrical portions F of said slots coincide while the notched portions F alternate, as described, of the shanks 0, each having a cylindrical portion for filling the cylindrical portion of said slots, and a pair of lugs, G G, located, respectively, above and below said disks, substantially as set forth.

3. In a pump-bucket,the combination,with the packing and a pair of disks each having key-hole slots arranged with their cylindrical portions coincident and their elongated or notched portions alternate, as explained, of the shanks 0, each having the lugs G G, located, respectively, above and below said disks and projecting in opposite directions, and the rod D and bolts 0 O, for forcing and holding the upper portions of said shanks in the directions in which their respective upper lugs, G, project, as explained.
