IMPROVEMENT IN PROTECTION-TIPS-FOR OAR-BLADES.

Specification forming part of Letters Patent N o. 191,923, dated June 12, 187'7;l application led May 24, 1877.

To all whom it may concern Be it known that I, MASON BRITTON, of Wauseon, in the county of Fulton and State of Ohio, have invented a new and useful 1mprovement in Protection-Tips for Boat-Oars, which is fully set forthin the following speciication and accompanying drawing. y

The object of my invention is to provide an improved protection-tip for oar-blades which shall be free from the objection of not yielding sucient to permit the expansion and contraction of the wooden oar-blade as the same becomes Wet or dry. The objection to which reference is made is such that, unless the tip is so constructed as tol possess a certain de grec of elasticity, its effectiveness as a real protection is greatly impaired.

Referring to the drawing, Figure 1 represents a blank of the sheet metal previous to swaging or stamping. Fig. 2 represents the tip ready for application to the4 oar, and Fig. 3 represents an oar-with my improvement.

The socket-tip A is first blanked out from any suitable sheet metal in the shape shown in Fig. l, the ends being bifurcated similar to a fish-tail, and is then swaged, stamped, or pressed by dies into the socket-shape shown in Fig. 2, corresponding to that oi' the end of the oar-blade B, which it should lit.

It may be fastened to the blade by rivets or' screws, or in any suitable manner; but I prefer to fasten it with annealed nails driven from each side through holes in the tip, and through the blade, the points of the nails cliuching in the wood on the opposite side as they come through .and strike the metal.

When constructed as herein shown and described it possesses the following advantages when applied to a wocdenoar-bladle: Being fastened at the bifurcated points or ends a a it has suicient elasticity at the narrow points c c to accommodate the swell 0r shrinkage of the wood, while always remaining tight to the edges of the oar-blade at the points d d,

whether the condition of the oar be wetor dry.

It will thus be seen my improvement is an effective protection-tip for the ends of wooden oar-blades, and will prevent them from splitting or abrasion, shielding the end when the oar is used in poling or pushing.

I am aware it has long been a practice to bind oar-blades withstrips of sheet metal to keep them from splitting. At best such devices but imperfectly serve any purpose, and do not afford any protection t0 the end of the blade, and I do not claim them but I claim and-desire to secure by Letters Pat- 1. As a new article of manufacture, the metal protection tip for boat-oar blades, pressed or stamped from sheet metal into shape for receiving the end of an oar-blade, having bifurcated ends a, substantially as shown and described.

2. The improvement in boat-oars consisting of the metal protection-tip A, with bifurcated ends a, substantially as shown and described, fitting over and secured to thc end of the'oarblade, for the purpose specified.

MASON BRITTON.
