IMPROVEMENT IN B-JNG-BUSH INSERTERS AND EXPANDERS.
Specification forming part of Letters Patent No. 218,871, dated August 26, 1879; application filed May 14, 1879.
a pivoted cross-head adapted to enter the bung hole and seize the under side of the stave, while the upper portion of the stem carries a revolving nut having projecting leverhandles, and terminating in a circular expanding head or die, which screws into the bunghole and expands the bush.
The annexed drawing presents an elevation of my improved tool, shown partly in section, and represented in the act of inserting a hungbush, which, with the bung-stave, appears in section.
As illustrated, A indicates a central screwstem, on which the other portions of the tool work. The lower end of this stem is forked or slotted, and in the slot is pivoted the crossbar a, one end of which is heavier than the other, so that when the stem is held vertical the cross-head falls in line therewith, enabling the stem to be inserted in the bun g-hole, when, by screwing the stem upwardly, the cross-head flies out at right angles, and is brought up tightly against the under side of the bungstave, as illustrated, thus obtaining an internal hold upon the stave.
B is the expanding-plug, which works as a nut upon the screw-stem A, its upper end being provided with the projecting lever-handles b I), while its lower end, which terminates in a smooth circular expanding die or plug, enters the bung-bush and rests against the annular rib of the bush.
The interior or bore of the expanding-plug is threaded to work upon the screw-stem, and its outside is also threaded to receive the inserting and clamping wrench (l, which is provided with projecting lever-handles c c, similar to the expanderB, and is free to screw up or down upon the expander.
The tool is used as follows: The bung'bush being placed in the bung-hole, the tool is held by the handles b b in a vertical position, and the wrench is screwed upon the expander, while the stem A is screwed down, so that its lower end projects well below the expander. The tool is then inserted in the bush, so that the cross-bar in the end of the stem passes below the stave, while the expander enters the bush, resting on or near the annular rib on the inner edge of the bush. The stem is now rapidly screwed upward, which brings the crosshead a at right angles to the stem, and close against the under side of the stave, as shown.
The Wrench 0 is now screwed downward against H the shoulder of the bush, thus forcing the bush tightly into the bung-hole, and bringing the shoulder of the bush tightly down upon the stave, and at the same time clamping the tool firmly in position for the expanding action. The expander is now revolved by turn ing the handles b b, and it is thus forcibly screwed into the bush, turning both on the stem A and in the Wrench (J, and the expanding end being thus forced against the ribbed edge of the bush, it expands the same outwardly and embeds the edge in the sides of the bung-hole, as illustrated, thus securely fixing the bush in the hole. The movements of the tool are then reversed and the tool re moved to insert the next bush; and it will be seen that the bushes may thus be inserted very rapidly and with great ease.
The use of the clamping and inserting wrench O 0 c, in combination with the expander and the central stem, is not essential but it is preferable.
What 1 claim as my invention is-- 1. A tool for inserting and expanding bungbushes, formed of a central screw -ste1n, A, having its lower end provided with a cross head adapted to enter the bung-hole and seize the under side of the stave, and of the screw plug B, provided with operating-handles, and arranged to screw upon the stem, with its lower end adapted to enter and expand the a nut 0n the threaded sides of'the expandingbush, substantially as herein shown and deplug: B, substantially as and for the purpose se'ribed. set forth.
2. The combination of the central screwstem, A, provided with a cross bar to seize I the under side of the hung-stave, and the ex- Witnesses: pending screw-plug B, Working on the said KING C. GILLETTE, stem, with the clamping-Wrench 0, Working as CHAS. M. HIGGINS.
