BOAT-OAR:

Specification of Letters-Patent; Pate t d J l 13 1920 Application filed October 1, 1919. Serial No. 327,617.

To all whom. it may concern Be it known that 1, DAVID D. PRICE, a citizen oi the United States, residing at Norman, in the countyot Cleveland and State oi? Oklahoma, have" invented certain reversing the direction of course on an oar whereby theoperator of a boat may face the bow of the same while rowing.

An important object of this invention is to provide novelmeans for adjustably securing the oarsfto the sides of the boat whereby the oars may be adjusted in any desired position with relation to the oarsman.

A further object o'l' the invention is to provide novel means for horizontally pivoting the car intermediate its ends whereby the oarmay bedipped in and out of the water. i

A further object is to provide a bow facing car which is simple, efficient, and cheap to install on row boats.

Other objects and advantages of themvention will be apparent during the course of the following description.

In the accmnpanying drawings forming a partol this application and in which like mimerals are employed to designate like parts throughout the same,

Figure 1 is a plan view of a row boat having my in'iproved bow facing oars ap plied,

Fig. 2 is a vertical section taken on line 2-2 of liig. 1,

Fig. 3 is a horizontal section through the reversing mechanism oi the oar,

Fig. 4t is a vertical section taken on line 4- 1 of Fig. 1, and,

Fig. 5 is a detail view of the car fastening means.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 generally designates a row boat having the usual gunwales 11 and transverse seats 12.

An elongated guide member in the form of a, rod 13 is secured to each gran-vale by depending brackets 141;. Bolts 15 extend through openings in the brackets and the adjacent portions oi? the gunwalc.

A carriage 16 is mounted on each rod 13 and has connection with a pair of upstanding spaced parallelstandards 17 having their lower portions bifurcated as indicated at 18 and arranged on opposite sides of the carriage 16. The bifurcated portions 18 may be welded to or cast integral with thesleeve portion of thecarriage 16. Set screws 19 have threaded engagement with the sleeve portion of the carriage and engage the rods 13 for securing the carriage in an adgusted position. The standards 17 carry a shaft 20 having one end portion provided. with a polygonal nut 21. A set screw 22 is carried by one 'of the standards 17 and engages the shaft 20 to prevent the same from rotating.

A supporting plate 23 is provided with a pair of spaced parallel depending bearings 24in the iorm' oi apertured ears. The bearings or apertureifl ears are horizontally pivoted to the shaft 20 inwardly ot' the standards 17, and they are equipped with compression oil cups 2 1. V

The plate" 23 is provided with coacting toothed segments 25. and 26 having attaching shanks 27 and 28 respectively. The toothed segments 25 and 26 are supported by upstanding pivot elements extending through the plate .23 and secured to the same. Suitable washers 3O surround the pivot elements 29 and support a cover plate 31 in spaced relation to the segments 25 and 26. The upper end portions of the pivot elements 29 have threaded engagement with nuts i 2 which serve to hold the cover plate and toothed segments in position.

An oar 33 is provided in its inner end portion with a slot 3d receiving the shank 27 of the toothed segment 25. Looking plates 35 have their end portions bent downwardly and over the sides of the oar 33 for forming retaining flanges 36. Bolts 37 on tend through the retaining flanges, the inner end portion of the oar and the shank portion of the toothed segment 25 for securely connecting the oar to the toothed segment. A handle 38 is secured to the shank 28 of the toothed segment 26 as is the oar 38 secured to the shank 27.

In the practice of my invention, the rod 13 is secured to the gunwale of a boat and a l, the rearward movement ofthe handle of the oar forces the oar rearwardly and therethe "carriage positioned at the desired point on the same. As is obvious from Fig.

by propels the boat in the direction faced by the oarsman. In horizontally pivoting the oars I am enabled to dip them in and out of the water quite as freely as oars of the usual construction;

While Ihave shown and. described the preferred embodiment of my invention, it is understood that such minor changes in arrangement and construction of parts may be made as will remain within the spirit of the ,invention and the scope of what isclaimed.

Having thus described myinvention, what Iclziimisf- V l. An'oarot' the class described including a support, arcarriage adjustably carried by the support, a plate horizontally pivoted to the -carriage,'a pair oi toothed segments vertically pivoted to the plate, and handles and p oars secured to the segments.
