Application filed August 8, 1911. Serial No. 642,936.

of Minnesota, have invented certain new and useful Improvements in Oars, of which the following is a specification.

This invention relates to improvements in oars, and particularly to the type of bow facing.

The principal object of the invention is to provide a sectional oar and a row lock by means of which the oar may be readily turned when in the water, or when desiring to feather the saine.

Another object is to provide an antifrictional bearing for the handle section of the oar.

Other objects and advantages will be apparent from the following description, and with particular reference to the accompanying drawings.

In the drawings: Figure 1 is a top plan View of the device attached to a portion of the gunwale of a boat. Fig. 2 is a side elevation of the device. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 is a section on the line 4-4 of Fig. 1. Fig. 5 is a view of the modification of the connection between the sections of the oar.`

Referring to the drawings, the device comprises a row lock consisting of a plate 1() having on each side the depending perforated ears 11, to which are pivotally attached the supporting bars 12. These bars are formed of any suitable material as flat strips of metal, twisted at right angles as at 13, so that the lower portion 14 thereof, may be attached to the gunwale of a boat. Thus the plate 10 is pivoted to rock laterally of the gunwale of the boat.

In one end of the plate 10 is swivelly mounted the ring 15, through which is adapted to move both longitudinally and rotatably the section 16 of the oar. The outer end of the oar is provided with the usual blade 17, while the inner has thereon the ferrule 18, formed with the lingers 19 having perforations therethrough between which is pivotally mounted a block 20. The other section 21 of the oar has on 4one end the usual hand grip 21', and on the opposite end a similar ferrule 22, also formed with the fingers 23, pivoted to the block 20, so that a universal joint is formed between the sections `of the oar, to permit a hinged, and a rotative movement of the sections.

In the form shown in Fig. 5, the sections of the oar are simply pivoted together by means of the hinge connection 24.

lThe plate 10 at its opposite end is formed with an extension 26, in which is formed a longitudinal slot 27, for the reception slidably therein of an anti-frictional roller 28. Secured to the upper face of the roller 28, and extending through the upper portion of the slot, is a ring 29, similar to the rst named ring, and through which the handle section of the oar extends.

In the operation of the oars it will readily be seen that upon grasping the handle and tilting the plate 10 outwardly the oar may be dipped into the water and a pull on the handle will draw the same through the water, in the common way to propel the boat. To return the oar to initial position for the next stroke, the handle is turned in the hand as in the manner of the ordinary oar, whereupon the roller will slide along the slot, so that the rings will turn, that the oar may be presented edgewise to the water, or feathered as desired. It will thus be seen that the oar may be given similar movement to the ordinary rigid oar, by means of the rings and the joint between the sections, thus providing the bow facing oar having the advantages of the rigid oar, in making it easier for the rower to see where he is going.

1What is claimed is:

1. In a rowing device, a row lock comprising a plate, means for pivotally mounting the plate on the gunwale of a boat, a slotted extension on the plate, a swiveled ring on t-he plate, a sliding ring on the plate adapted to operate in the slotted extension, and oar sections pivoted together and mov able through the rings, and rotatable therein.

2. In a rowing device, a plate, an eXtension on the plate having an elongated slot, downturned ears on the plate, supporting bars secured to the gunwale of a boat, said supports being pivotally attached to the said ears, whereby the plate is capable of pivotal movement transversely of the gunwale, a swiveled ring arranged upon said plate, an oar section slidably and rotatably mounted in said ring, a roller movable longitudinal in the elongated slot, a second ring mounted on the roller and movable there- Water by means of the pivotal movement of 10 with, a second oar section slidably and rothe plate.
