Patented Sept. 14,; 1920.

* cairn!) sir WILLIAM nnnnricriar, or ,Ens'rrs, FLORIDA) nowglrlecineeenf To a ll whom it may 00mm The invention has for its object, among' other things, to provide an oar simple in construction, of the minimum number of parts, easy of operation and readily applied to the gunwale of the boat. I g A further object is to'a-dapt' the oar to take care of itself when released as upon the cessation of the rowing operation or the oar is not in use. V

A still further object is to provide for carrying out with facility and economically, the aforesaid objects together with others i which may be apparent from the following description and illustration of the inven-' tion. 1

The invention consists, therefore, of cer tain instrumentalities and features of construction substantially as hereinafter more fully disclosed and defined by the appended claims. V I

The accompanying drawing illustrates the preferred embodiment or one form of 7 my invention wherein it will be understood that various changes and modifications as relate to the detailed construction and arrangement of parts may be made without departing from the spirit or scope thereof as covered by the claims.

In'the drawing: Figure l is a plan view of my invention; Fig. 2 is a longitudinal section thereof. Fig. 3 is a detailedtransverse sectional view, taken upon an enlarged scale, showing more fully the pivotal connection between the members of the oar and the rail or keeper therefor attached to the gunwal'e.

As characteristic of my invention, I form the oar, generally designated as 1, in two members, the blade or oar proper 1 and the handlel", these constituting practically a single unit. The blade 1 and handle 1 arepivoted upon a common pivot or pintle Application filed ember a7, 1919.

2,;having its lower end terminating inia ring-formation 3 receiving the I longitudinal PQItiongof aljkee per or; rail '4 suitably jsecured to the boat-gunwale. The pivotalcon-v nection between theblade an'd handle mam,

bers 1, 1", and the pivot or pintle 2 is effected preferably by providing said blade and handle members each with opposite or a pair of metallic straps or plates 5 suitablysecured to the respective opposite sides of said members, eachpair of said straps or 1:

plates terminating in orificed or apertured extensions 4; whose orifices receive said,

pintle or, pivot 2; The pivot or pintle 2 is preferably provided with a washer 3 which limits the downward insertion of the orificed pivoting extensions 4? of the blade and handle members 1, 1*, respectively.

freely connected to a sleeve or tubular mem-' her 6 slidably mounted upon :the rail or keeperel, said connection including inflexible members, links or rods 7 having terminal connections with said blade and handle and said sleeve, comprising" preferably eyeended members? threaded into the handle and blade,;and lateralapertured extensions I t or flangesT of thesleeve, which eye-ended members and flan es receive hooked terminals of said rods or links. 1 ,7

From the aforesaid arrangement of parts," i. e. the connection of the handle and blade with the rotatable. T-member carried, pivot 01" pintle, mounted upon a rail carried by the boat-gunwale and the inflexible links and slidablesleeve connection between'the boat-gunwale rail and the blade and its actuating handle, the handle and blade of the oar are adapted to be extended-to alinement transversely of the longitudinal. or median planeof the boat, preliminary to making the initial stroke, andsuccessively".

to cause the blade to conform tothe usual movement in submergence mproducing the propelling strokeas the handle is actuated,

The connection between the connecting rods 7 and the blade and handle members 14, 1", of theioar 1, may be adjustably effected by providing additional eye-bolts 7 to said handle and blade members, as shown in l, as may be required in obtaining a vari-. able stroke. a

t is believed that theadvantage -"simplicity, and facility of manipulation of my invention haye been made clearly appar V V 75 The blade. and handle members 1*, l ,'are r cut from the foregoing description of the construction and operation thereof.

Having described my Linventi mHWhat I claim and desire to secure by Letters Patent 1s: 7

1. The combination of an oar including a' blade 4 handl zmembfi an me ns -pI-0- viding. for a freely movable; connection be tween said handle-member and blade, and a a comp i ng a f ai secure to th gu Wale of 1 9 b a mean .refiec ngeag lidi g n t on be e n sai bal dl i and blade I and said rail, and a pivoting member having 2. The combination of a handle member tudina'lly positioned upon the gunw'ale of the 'boat and passing through said annular headyamember sliding upon said ro d and haying adjustable connections With said handle ineinber 'andsaid blade member.
