To all wtomfit muy# concor;

zen of the United Statesiresiding Wellson, county of Jacksonfand'tate of Ghio, have invented certain new and useful lin;- provements inBovwFacing Oars, or which f the following is a specification.

My invention relates'to rowing .devices ory oars and particularly to- 'that class thereof'4 known as bow `facing oars.

'The `objectofiny invention isv to provide Aan improved device of the class mentioned Wherebythe oarsman may face the bow of the boat and at the same time propel the boat with the saine stroke as used with the A further object of my invention is to provide a device of the class mentioned which maybe readilysecnred by any one to. the gunwale of'agbo'atj without thel use of tools and irrespective'ofv the curvature of the gnnwale at'the place of attachment.

Other objects will appear hereinafter.

With these objects inview my invention consists generally inr a housingcomprising apair of parallel-'substantially horizontal plates, a pair of intermeshing segment gears Y rotatablylrnounte'd between the plates and each provided with a socket to receive the Shanks of the oar blade and. handle' respec- Y. tively, and a pair of brackets viswiveledbe tween the plates of the housingand provided V3 with clamps for engaging the gun'wale t' lily invention further consists in various details of construction and arrangements of parte all as will 'beully described hereinafter and particularly pointed out' in' the- My invention will bernore readily under stood by reference to the accompanying drawings forming a. part of this specifica-4 tion and in which- Figure l is a tcp plan view of a rowing device embodying my invention in its preferred. form, a portion of the top plate of the housing being broken away, 2 is a vertical longitudinal section on snbstan tially the line of Fig. l, and Fig.- 3 is a transverse section on the line oi" Fig. L

Referring new to the drawingl and 2indicate the upper and lower plates respectively which form the housing, These are arranged substantially horizontal and n allel and are preferably provi 'ned .i with rounded ends 3. ltotatably mount t' Be 1t known that I, Dimmi, Donn, a c1ti. b

vto receive the Shanks 9v upwardly etween the plates l and 2 upon pins or .rivets al which serve to secure said plates tois a pair of internieshing segment' gether,' gears 5 and 6, each provided with a radially extending stem 7 terminating inA a. socket 8 and 10 of the oar blade and handle respectively.

' In orderto attach Vthe housing and the contained nieclianisinto the gunwale of the boat l provide the saine withr a pair of brackets each formed with a clamp to' engage the gunwale, and inl order that the vdevice may be readily secured to the side of any row boat irrespective of the curvature of the gunwale l pivotally connect clamps to the housing. To this "end each bracket comprises a. blockv l1 swiveled between the plates l and 2 at the sides thereof7 upon pins l2, and a clamp lrconnectcd thereto. To permit the oar to be raised a d lowered in the ordinary manner, l prefer to swivel the block 1l 'upon the clamp 13 so that the housing and mechanism may readily turn upon a horizontal transverse axis. Accordingly,

proJecting. ear or lugl/l and the block 1l is formed with a horizontally pro- 5V swiveled in the ear 1li, as

shown; clearly in Fig. 3. To facilitate at 'tachingithe device to the 'gunwale A the g 'pair'of' dependingV members ltiadaptedv to embrace the gunwale clamps'are 'formed of a and vthreaded through onel of seid members is a' thumb screw 17.

'The inanner of attaching the device to the boa-t and of operating'the same is obvious and does not need detail. description.V

Having thus described my invention what l'yclaiin as new and desire to secure by' Letters Patent is :'-1

l, ln a device'. of the class described, a housing comprising a pair of parallel substantially horizontal plates, .a pair'of in# termeshing segmentv gears rotatably mount; ed between said plates, sockets formed on said gears? to receive the Shanks of an oar blade and handle respcctively, a pair of brackets swiveled between the plates of said honsingto lturn upon a vertical clamps formed on 'said tially as described, Y

2. ln a device of `the class described, a housing comprising a pair oi parallel suhstantially horiZorngal"plates3 a pair of brackets, substaneach clamp 13 is formed with an" aXis,. and 211% l termeshing segment gears rotatably mounted between sind plates, sockets Xecl to said gears to receive the Shanks of an oar blade and. handle respectively, u pair of blocks swveled between the plates et the sides 'thereof and each providedv with a horzon telly extending pin, clamps adapted to be secured to the gunwale of a boat and formed with upwardly extending ears, said pins be' ing swiveled in said ears, substeltially es 10 described.

In testimony whereof I have signed my name to this specification in. the presence of two subscribing Witnesses.
