UNITED STATES GEORGE W. DOXSIE, OF CADILLAC, MICHIGAN.

OAR-BLADE.

Specification of Letters Patent Patented. May 14, 1907.

Application filed February 6, 1907. Serial No. 356,063-

To all whom it may concern.-

Be it known that I, GEORGE W. DOXSIE, a citizen of the United States, residing at Cadillac, in the county of Wexford and State of Michigan, have invented certain new and useful Improvements in OarBlades; and I 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. I

The object of my invention is to provide an inexpensive oar-blade, possessing lightness andstrength, and adapted for attachment on a suitable handle to make the car complete; so that boatmen, canoeists and others may avoid the expense of purchasing complete cars, and instead may order only the oar-blades and a'Hix them on home-made or other suitable handles, which can be constructed or produced very cheaply.

To this end, the invention consists of the improved device substantially as hereinafter described and pointed out in the appended claim; reference being had to the accompanying drawings which form a part of this specification.

In said drawings, Figure 1 is a face view of an oar-blade embodying my invention, shown attached on a handle; and Fig. 2 is a cross section of the same.

My improved device is constructed of aluminium, and as an integral article, combining lightness and strength. It comprises a blade a, of the usual or any appropriate form, having at one end a short socketed stock I) interiorly screw-threaded to receive the threaded end cl of any suitable handle 0; the said stock being further provided with a lateral screw,- hole to receive'a setscrew e for engaging the handle and preventing the blade from turning thereon. The blade is thickest adjacent to the socket, and gradually diminishes in thickness toward the opposite end while the back of the blade is formed with a medial longitudinal strengthening rib f, extending from the stock and gradually merging in the surface of the blade, near the outer end or which is moreover a relatively inexpensive article, so that the loss or damage of the blade will not entail the cost ofreplacing a complete oar. The blades may be furnished to boatmen, canoeists and others, who can make their own handles, which of course can be done very cheaply. The blades may be shipped either singly or in quantities in small packages of light Weight, and consequently at. a slight expense. Boatmen, fishermen and others may carry along one or more extra blades, to be used in cases of emer gency by a'liixing them on suitable improvised handles which of course is much easier than trans orting extrafull-sized cars.

It will be un erstood that my improvement may be embodied in any form of oar or paddle commonly used, such as flat or spoon-blades, sculls, paddles, etc.

The term aluminium is intended to cover alloys or compounds thereof commonly known as aluminium or of substantially similar characteristics or properties as to light ness andstr'ength.

I claim:

As a new article of manufacture, an oarblade made integrally of aluminium, having a short socketed stock interiorly threaded to screw on a handle and provided with a lateral hole to admit a set-screw to hold the blade from turning on the handle, the blade being thickest at the stock and gradually diminishing in thickness toward its opposite end, and the back face of the blade having a medial strengthening rib formed thereon extending from said stock along the length of the blade and gradually merging in the surface of the blade, substantially as described.

In testimony whereof I aHix my signature, in presence of two Witnesses.

GEORGE W. DOXSIE. Witnesses:

D. E. MCINTYRE, D. C. LAMOREAUX.
