This invention relates to an improved oar or canoe paddle.

The primary purpose of the invention is to provide means to prevent splitting of the I blade or its tip;to prevent warping or cracking; and to achieve these results without affecting the spring or flexibility of the blade.

With the above and other objects in view which will appear as the description proceeds, the invention consists in thenovel features hereinafter described 111 detail, illustrated in the accompanying drawing, and

more particularly pointedout in the appended claims. 7

In the drawing, i

Fig. l is a plan view partly broken away of an oar blade equipped with my improve ments.

Fig. 2 is a longitudinal sectional view of a portion of the same on the line22 of 1.

Fig. 3 is a sectional view on an enlarged scale taken on th-eline 33 of Fig. 1.

In accordance with the present invention, a

i wood blade 4 having the grain running lengthwise thereof, is provided with a slit 5 whichpenetrates the same only a relatively slight distance from the tip 6 and receives a wood insert 7 Whichhas its grain running transversely of the blade. The insert is secured in position by any suitable means, such as an adhesive.

While the insert will prevent splitting of the blade or its tip, and will also prevent warping or cracking, it will accomplish these it is manifest that the cost of the same will.

be less than in the known constructions.

While I have disclosed what I now considv 1 er to be a preferred embodiment of my inventlon, 1t is manifest that changes may be made in the details disclosed, without departing from the spirit of the invention, as

expressed in the claims. .What is claimed and desired to be secured by Letters Patent is:

tip end with a reinforcing insert which extends through the tip end only of the blade.

2. An oar having ablade provided at its the grain of the insert being arranged at right angles to the grain of the blade, the insert 1lgieing of a length less than one-quarter of the ade.

In testimony whereof, I havesigned this,

specification.

results without in any way afi'ecting the spring or flexibility of the blade.

Heretofore it has been proposed to reinforce an oar or canoe paddle by making the same of laminated construction, or by using an insert in the blade, but in each instance,

the reinforcing insert extends the full length of the blade, and consequently,'the oar-or paddle is robbed of its usual resiliency. My improvement will not alone reinforce the blade without affecting the resiliency of the same, but as the slit extends only a relatively short distance into the blade from its tip, the blade will not be weakened by the slit, and

53 besides, as a much shorter insertis employed,
