WILLIAM ORONK, OF HAVANA, NEW YORK.

POST AND STAKE BAR.

SPECIFICATION forming part of Letters Patent No. 318,601,6.ated May 26,1885.

Application filed May 14, 1884. (Xo model.)

T0 @ZZ whont it may concern:

Be it known that I, WILLIAM GRONK, a citizen of the United States, residing at Havana, in the county of Schuyler and State of New York, have invented a useful Improvement in a Combined Post and Stake Bar, of which the following is a specification.

My invention relates to that class of tools used for setting fence-posts, hop-poles, stakes, dto., and is commonly called a post-bar, and the objects of my improvements are, first, to provide a combined post and stake bar in one tool; second, to get in making a large hole for fence-posts in hard soil the advantage of making a small hole first, then expanding it by degrees; third, to obtain lightness with sut'cient diameter in the tool. I attain these objects by the device illustrated in the aecompanying drawings, in whieh- Figure l is a vertical section of entire tool with No. 2 hole-expander attached. Fig. 2 is a plan of entire tool. Fig. 3 is a vertical'section of No. 3 hole-expander. Fig. 4. is a full plan view of same. Fig. 5 is a side view of detachable steel point. Fig. 6 is a plan view of same.

Similar letters refer to similar parts througlr out the several views.

In making the bar I cut from gas or other pipe the handle a, one end of which I place in the mold in such a manner as to cast in line and rigidly about it the conical expander G, which nI will term No l, which is very tapering to penetrate easily and expand the hole thus penetrated to a size desirable for stake-setting. Into the pointing end of this No. l expander C, I insert a steel point, d, by screw-thread or other means, whereby it may be taken out and repointed to secure durability and ease in Working.

b and b represent a series of independent holefexpanderawhich I willterm No. 27 and N o. 3, respectively. These are in form somewhat pear-shaped, and cylindrical shells having a tapering hole through them of right taper to slip upon and tighten upon the cast portion or No. l expander C of the bar, and to hold thefbar steady and get the best effect the diameter of the lower end of each of these expanders should be equal to the diameter of 5o the larger end of the preceding one used.

Post-bars of much Weight having a rigid and solid expander have been used; but I am not aware of a light combination-bar having detachable expanders ever having been used.

Having thus fully explained my improvement, what I claim, and wish to secure by Letters Patent, is

1. In a post and stake bar, the combination of eXpanders C and b', substantially as set forth.

2. The combination, with the eXpanders C and b, of the hollow handle a, substantially as set forth.

3. In a post and stake bar having detachable expanders, the combination, with the eX- panders G and b, of the detachable steel point d, substantially as set forth.

WILLIAM CRONK.
