' SHIELD AND BRAGE FOR TOOL HANDLES- Patented Mar. 9, 1897.

UNITED STATES PATENT OFFICE.

REINHOLD O. DOENITZ AND JOSEPH FIEREOKEL, OF IRON RIVER, MICHIGAN.

SHIELD AND BRACE FOR TOOL-HANDLES.

SPECIFICATION forming part of Letters Patent No. 578,319, dated March 9, 1897.

Application filed December 11, 1896. erial No. 615,286. (No model.)

T 0 all whom, it may concern:

Be it known that we, REINHOLD O. DOENITZ and JOSEPH FIEREOKEL, citizens of the United States, residing at Iron River, in the county of Iron and State of Michigan, have invented certain new and useful Improvements in Shields and Braces for Tool-Handles; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to guards or shields for tool-handles.

The object of our invention is to provide a guard or shield of this character adapted for either a double or single bitted tool.

It is also our object to provide a guard or shield which shall also serve as a brace to strengthen the handle, and in this respect to be also adapted for tool-handles which from constant use have become worn or partly broken away upon the under side adjacent to the tool.

It is also our object to provide a shield and brace adapted to be applied to a tool-handle without first removing the tool from its handle and without the use of nails, rivets, or screws, or other means which tend to weaken the handle.

It is also our object to provide a shield and brace adapted to bear against the rear and lower end walls of the tool-eye to prevent it from working on its handle.

In the accompanying drawings we have shown our invention as applied to an aX-handle; but it is evident that it is also applicable to other tool-handles of similar character.

Figure 1 shows our brace and shield applied to a double-bitted ax, and Fig. 2 shows it applied to an ax having a single bit. Fig. 3 is a side elevation of our shield and brace detached; and Fig. 4is cross-section of the same, taken on the line 3 3 of Fig. 3.

Referring more particularly to the drawings, A denotes the ax, and B denotes the handle.

0 denotes the brace or shield, formed of one piece of malleable iron, bent as shown in Fig. 4,. its upright end walls a being slightly concave to bear against the ax, upon each side of and under the eye of the same, while its side walls 0 taper rearwardly to nothing. The edges of said side walls, as shown in Fig. 2, are bent or tumbled inwardly toward each other, and in said tumbled edges are filed teeth 0 Owing to the tapering side walls the teeth will bear crosswise of the grain and avoid any possibility of weakening or splitting the handle when they are driven home.

Our brace and shield are applied to the axhandle after the ax is handled, and it is secured in position adjacent to the ax simply by hammering the sides of the shield until they yield and allow the teeth to bite into the handle. The upright end walls 0 are made conveX'to meet the concave contour of the adjacent end of the ax.

In adjusting the shield the upright end Walls 0 are fitted snug to the rear end walls of the aX-eye before the shield is clamped in position. As the walls 0 bear against the ax they prevent it working rearwardly on the handle and wearing or chafing the same, thus loosening the ax.

It is evident that when a tool-handle has become worn from use our shield and brace will bridge over the worn place in the under side of the handle, while its side walls will project above it and grasp the tool-handle upon all sides of said worn place, thus bracing said handle, besides preventing further wear of the same.

Having shown and described ourinvention, what we claim, and desire to secure by Letters Patent, is

A shield and brace for tool-handles formed in one piece adapted to fit the handle exteriorly of the tool proper having upright end walls and yielding side walls having toothed edges which slope or taper rearwardly from said end walls, whereby said edges enter the ax-handle crosswise of the grain, substantially as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.
