BOW-FACING OAR.

SPECIFICATION forming part of Letters Patent N 0. 727,731, dated May 12, 1903. Application filed February 19 1903; Serial No. 144,102. (No model.)

which it appertainsto make and use the same.

This invention relates to improvements in bow-facing oars.

The object is to provide a construction whereby an oarsman may sit facing the bow of the boat while rowing in the usual way to propel the boat forward and whereby the car may be readily manipulated to move the blade into and out of the water and as readily applied to and removed from the fixed part of the oar-lock.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully de scribed, and particularly pointed out in the appended claim.

In the drawings, Figure l is a top plan view showing only so much of the oar and sideof a boat as is necessary to illustrate the invention. Fig. 2 is a cross-section through the side of the boat, showing the invention in end elevation. Fig. 3 is an inner side view. Figs. 4 and 5 are sections taken, respectively, on the lines t at and 5 5 of Fig. 1. Fig. 6 is a detailview of one of the oar-sections and its gear.

Referring now more particularly to the drawings, the numerals 1 and 2 represent, respectively, the handle and blade sections of an oar, which are provided at their meeting ends with gear-segments 3 and 4., meshing with each other and adapted to transmit motion from the said handle-section to the said blade-section. Each of these segments is provided with a pair of parallel plates 5,- which fii within recesses formed in opposite sides of the coacting oar section and are secured thereto by bolts 6. The gears are inclosed within a casing open at each end and consisting of top and bottom plates 7 and 8, connected by side pieces 9, and the oar- sections 1 and 2 are pivoted to said casing by means of bolts 10, so that when movement is imparted to the section 1 the latter will transmit a swinging movement to the section 2 through the 'instrumentality ofthe two gears 3 and 4. By this construction it is obvious that when the car is suitably mounted upon a boat the oarsman can sit facing the bow and by operating the handle-section 1 transmit reverse swinging motion to the section 2 to propel the boat forward.

The bottom plate of the casing is provided with depending ears 11, through which passes a bolt or shaft 12,-mounted upon a yoke 13, which is provided with a stem 14. The casing is adapted to pivot on this shaft or bolt to adapt the latter to be raised and depressed in the operation of rowing to move the blade into and out of the water.

The yoke 13 has a fiat base-plate which fits within a correspondingly-shaped channeled socket 15 upon the top of a bracket 16, secured by bolts 17 to the side 18 of the boat or a plate or board attached thereto. Through the socket extends an opening 18, which is in line with an opening in a lateral ear 19 at the lower end of the bracket. The stem 14 fits within these openings and secures the yoke to the bracket in such manner as to allow the oar to be readily applied to and removed from said bracket, andthe oars also will swing to rest on sternof the boat. The yoke fits snuglywithin the channeled socket and is held by the stem 14. against longitudinal movement and by the side flanges of the socket against lateral movement, thus preventing the yoke from having any independent play when the oar is manipulated.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the inven tion will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be ciple or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
