HANDLE FOR TOOLS.

I at

SPECIFICATION forming part of, Letters Patent No. 224,786, dated February 24, 1880.

Application filed March 6, 1879.

To all whom it may concern:

dle not only at the upper end of the confining" I ferrule, where it is most liable to break from a T the necessary jars, blows, and strain, but to a give it a yielding strength throughout its entire length. It is well known that the handles of picks,

hoes, hammers, rakes, and the likeare usually provided with ferrules,which receive the shank of the tool, or other securing means. In such constructions the ferrule is an element of strength to the handle so far as it extends but at or near the point where the ferrule and shank terminate is foundthe weakest part of the handle. To obviate this difficulty thisinvention is designed.

In carrying out my invention I employ an ordinary "wooden handle bored through its longitudinal center from end to end. The central bore thus formedreceives a wrought-iron 3o. jnamental button or head and at the other or steel rod provided at one end with an orwith a screw-thread toreceive a confining-nut. The turning and boring of the handle may be done at one or separate operations, and the inclosed rod is readily applied. Thisrod not only strengthens the handle throughout its entire length, but in practice it forms a part of the handle, and is not liable to be mislaid or lost. -Its binding-bearing operates against the ends of the longitudinal fibers of the wood, I and thus not only strengthens the handle by its lateral strength, but by the said bearing upontheends, governed by the nut, its strength is multiplied.

At the tool end of the handle I provide a ferrule of smaller diameter than the handle,

which is cutaway to accommodate it. This ferrule has a closed head, except where it is perforated to receive the central rod, and is provided with tenons, which are received into corresponding mortises in the tool proper.

It will thus be observed that while the head of the rod is adapted to bear. against the longitudinal fibers of the,handle at the free end, the ferrule bears with its entire area upon the ends of the fibers at. the opposite end.

Bands or ferrules are provided at proper distances apart along. the handle, as shown.

The tool is provided with acentral aperture to receive the central rod, and with piortises to receive the tenons on the ferrule, and the portions of the toolleft between the central aperture and the mortises bear directly upon the head of the ferrule.

In this construction not only is the handle strengthened at the weak point before mentioned, but the pressure upon each end of the fibers exerted bythe confining-nut is an element of great strength to the wood, in addition to the strength of the rod itself.

Referrin g to the drawings, Figure l is a view of the inner face of the tool; Fig. 2, a section thereof; Fig. 3-, a longitudinal section of the handle, and Fig. 4: a top View of the ferrule.

Similar letters of reference indicate like parts in all the figures.

I A represeirt'sthe tool, A the central aperture, and at the mortises.

B represents the wooden handle, bored through its longitudinal center, as shown, to receive the rod 0, having threaded portion 0, and provided with rounded head 0. The wooden handle is cut away, as shown at b, to

accommodate a ferrule, B, having head 0, perforated at e to receive the rod 0, and provided with tenons d, which operate in the mortises a of the tool A.

b I) represent bands or ferrules, and c the confining-nut. v I am aware that mortises and tenons have been employed heretofore for similar purposes,

and that the tool has been made removable by "nut and screw connections; but in such constructions the confining means and ferrule end at approximately the same point, and the handle proper is proportionately weakened at that point by being cut away or bored to accommodate such devices. This construction is shown in PateutNo. 88,884., of April 13, 1869, upon which this invention is designed as an improvement.

I am also aware that a socket has been em ployed to receive the tool proper and hold it securely against the free end of the handle. This socket is secured to or formed in one with a hollow rod which extends through the handle and is held by a nut, as shown in Patent No. 32,249, of 1861; but such construction is expensive, complicated, inconvenient, and unreliable. The socket can operate only with peculiarly-formed tools. The tool is liable to turn upon the handle, and the toolhas to be made in such form, with shouldered recesses, as to adapt it to the handle. None of these constructions are sought to be covered by this application.

1 deem it important to obviate the necessity I of partially removing the central rod when ever it is desired to change the tool, as, from swelling of the wood or rust when exposed to the weather, the rod is liable to bind and be difficult to move within the handle. In my construction this fault is entirely avoided.

What I claim is In a tool-handle, the combination of the centrally-bored wooden handle B b, as shown, and the ferrule B e e d, with the solid rod 0, having rounded head 0 and threaded portion 0, formed in one, and with the nut 0 and tool A A a, as and for the purposes specified.

In testimony that I claim the foregoing as my own I affix my signature in presence of 0 two witnesses.
