To all 'whom t mcy concer/n.:

Be it known that I, RUDOLPH HENRY S'roBBE, a citizen of the United States, re-

siding at St. Clairsville, in the county of Belmont and State of Ohio, have invented certain new and useful improvements. in a Bow-Facing Oar, of which the followmg is a specification. l

This invention, relates to improvements in bow facing oars and `has for its principal object to provide a means wherebyl an oarsman may face the same direction as thepropulsion of the boat in which he is seated.

VAnother important object of the invention is to provide a bow facing oar of the above mentioned character, which.' will reduce friction to a minimum, the same being further adapted to be easily `:moved into or out of the water.

A' further object i's to provide a bow facing oar of the above mentioned character, which is simple in construction, inexpensive, strong and durable and furthermore adapted for the purposes for which it 1s atcd.

Other ob'ects and advantages ot this invention w' 1become apparent during the course of the following description.

ln the accompanying drawing forming a part of this specification and in which like numerals designate like parts throughout the same:

Figure l is a top plan view of the present invention.

Figure 2 is a side elevation thereof.

Figure 3 is a view taken at right angles to 1 re 2. E A

In t e dnawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, thenumerals 1 and 2 designate a air of supporting brackets, the same beiiig substantially of inverted U-shaped design and adapted to be clamped` in engagement with the gunwale of a boat by means of the fastening bolts 3. The supporting brackets 1 are spaced from each other and provide a means for 'pivotally supporting therebe- -The shaft 4 is provided with the trunnions 5 at its respective ends and the same are adapted to extend through suitable openings provided therefor in the upper portions ot the brackets. in the mannerv clearly illustrated in Figures 1 and t3 of `from and whenin use wil the drawing. For the purpose of reventing the displacement of the shaft om belllltween the brackets, anges, such as are f I shown at 6 are provided on the shaft adjacent the ends thereof and adapted for engagement with the inner opposed faces of the brackets. ,The shaft 4 is supported between the brackets so as to be spaced from 4the gunwale .A and the shaft ils furthermore provided with -a flattened face 7,'

the purpose of/which will hereinafter be more fully described. 1

Murad to the dat face 7 of the shaft 4 are the spaced upper and lower. lates 8 and 9 respectively. The bottom p ate 9 is j sgured to the face 7 i of the shaft d vt 10 while the upper plate is secured in spaced relation to the lower plate 9 through the medium of the fastening members 11.

Rotatably supported between the upper and lower plates 8 and 9 respectively are the -intermeshing segmental gears 12 and -13 respectively. The supporting means for ars as illustrated each of the segmen at 1d inthe drawing. xtending radially from the segmental gears 12 and 13 are the hollow stems or socket members 15 and 16 res ectively,` the' same providing a means or receivin an oar blade and spectively.

With the parte arranged as shown in the drawing, an oarsman mayspace the bolts the shank portions of andles 17 and 18 relrough. the medium of the fastening bolt in the same direction in vwhich the boat is being propelled and the intermeshing segmental ear will transmit motion to the oar bla' es to cause the same to properly and ecien-tly operate in 'propelling the boat.v Eurthermore the oar blade maybe moved into or out of engagement with the water by raising'or lowering the handle 18 and causing the. shaft 4 whichl carries the plates and the segmental the Shanks of the oar bla es and handle respectively are fastened to rock or oscillate between the brackets.

The simplicity in which my im roved -bow facing oar is constructed enabes "the parts to be readily and easily 4assembled and when in position on each of the gunwa-les of a boat, the same will be supported against accidental disengagement therereduce the friction to a minimum.'

While I have shown thev preferred emears to which shap and -armngme'nt of parts. may be resor Wiithout depsu't-ing from the spirit of the invention and the 4scopa of. the i ap ened el@J wing mus 'described the invmim, what I cl isz- An om' structuur@ comprising bra/skew,
