TOOL-HANDLE.

SPECIFICATION forming part of Letters Patentflo. 401,481, dated April 16, 1889.

Application filed April 26, 1888. Serial No. 271,883. (No model.)

To all 1071 0721, it may concern.-

Be it known that I, GEORGE CARLISLE, a citizen of the United States, and a resident of Attleborough,in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements inTool-Handles, of which the following is a specification.

My invention relates to tool-handles which are provided with a tip of horn or other hard and durable material adapted to receive the' force of a blow from a hammer or mallet; and the purposes of my invention are to cheapen the cost of manufacture of such handles and to provide a durable tip of a form which practical tests have demonstrated to be best adapted to fulfill the requirements and be free from the liability to chip or break ofl' under repeated blows, which I have found inheres in other forms of tips or handles even when of the character of that for which I obtained Letters Patent No. 154,83-l, dated September 8, 1874.

In my present invention I construct the tip of horn or other hard and durable material and larger at its base than at its top. I fasten the tip in the handle by a ring adapted to compress a portion of the wood of the handle upon the tip incased in the handle. The base of the tip is plane, and there being no shoulders or projections on the tip the full force of the blow is received and distributed evenly. The tip, being closely incased in the handle, cannot be chipped or broken off by the blow. The tip projecting slightly above the handle top receives the full force of the blow, the hammer or mallet not coming in contact with the wooden portion of the handle at all.

In the accompanying drawings, which are hereby made a part of this specification, in Figure 1 is shown a handle with the upper portion broken away and the tip and bin din gring in section. Fig. 2 is a horizontal section on line a: w of Fig. 1. Fig. 3 shows a modification of the tip.

A represents the handle and B the tip,which is of horn or other durable material and may have its sides tapered from. base to top 5 or it may be straightsided to within a short distancesay one-fourth of an iuchfrom the top, and be tapered from that point to the top, as shown in Fig. 3.

I do not wish to be understood as limiting the scope of my invention to any specific degree of taper or to any fixed form of the tip B. The degree of taper-e'. a, the difference in crosssection of base and apex of the tipmay vary within quite considerable limits without departing from the principle or impairing the efficiency of the invention.

C represents the binding collar or ring, which I prefer to have of the form described in my said prior patent that is, straight on the outside and tapering on the inside-as by the use of this form of binding ring or collar I avoid the danger of splitting the handle in driving the ring to place.

The function of this ring is to compress an annular portion of the material of the handle about the tip near its top with sufficient snugness to confine the tip within the handle. The material of the handle may or may not be brought into actual bodily contact with the tip immediately below the ring or between the lower edge of the ring and the base of the tip. The tip has a firm rest upon its base, and the annular portion of the material of the handle compressed about the top of the tip and for a reasonable distance down the same is amply sufficient to rigidly secure the tip in the handle.

I bore a hole longitudinally in the handletop and insert the tip until it is nearly concealed. I then drive the ring C to place, flush with the top of the handle, thereby compressing that portion of the handle lying between the ring and tip and securely and rigidly fastening the tip in the handle. The tip will then project sufficiently above the top of the handle to receive the impact of the hammer and protect the handle. The base of the tip is a straight or plane surface, and the force of the blow is imparted solidly to the handle and in the central longitudinal line of the handle.

By this construction and arrangement I am enabled to use a body of horn or other durable material of less diameter than the handle, and the ring affords an additional protection to the handle and a guard against the tendency of the wood to chip orbreak off undera blow of the hammer or mallet. The ring 0, although necessarily of larger diameter than the tip, is still much less in diameter than the handle. In view of my said patent, No. 154,834, I do not herein claim broadly a horn or hard tipped handle.

I do claim as my invention and desire to secure by Letters Patent 1. The tip B, of horn or other durable material, having greater cross-section at its base than at its top, combined with a handle, A, and binding ring or collar 0, said tip being nearly concealed within said handle and rigidly secured therein by compression of a portion of the encompassing material of the handle.

2. In a tool-handle, the described tip composed of horn or other durable material and having a plane base of greater cross-section than the top of the tip, combined with a handle, A, of greater diameter than the tip, said tip being, as shown and described, nearly concealed in said handle and rigidly secured therein by compression of a portion of the immediately-surro unding material of the handle.

In testimony whereof I have hereunto set my hand, in presence of two witnesses, this 3d day of June, 1887.

GEORGE CARLISLE.
