Bow-FACING OAR.

SPECIFICATION forming part of Letters Patent No. 537,616, dated April 16, 1895.

Applicationiiled March 23, 1894. Renewed March 12,1895. Serial No. 541,486. (No model.)

To all whom t may concern.-

Be it known that I, REINHOLD H. PAAR, a citizen of the United States, residing at Carthage, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Bow-Facing Oars; and I do herebyfdeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the sam e.

My invention relates to improvements in oars for boats, which consists in new and automatic feathering devices, to facilitate the operation of the same, in combination with appropriate actuating mechanism and novel features of construction, which will be hereinafter described and pointed out in the claim.

The object of my invention is to provide an oar for row-boats, whereby the oarsman can face the bow of his-boat, and operate the same plates.

with perfect ease; thus overcoming dangers in navigating crowded waters.

In the accompanying drawings similar letters of reference indicate like parts in the several figures.

Figure l''' is a top plan view of my improved feathering oar. Fig. 2-L is a side elevation of the same, attached to a section of the boat in position for rowing. Fig. 3- is adetailed plan View of the sector and pivotal link. Fig. et-is a cross section of the same. Fig. 5- is a detail view of the hinge. Fig. 6 is a modification of the coupling for the handle, and blade of the oar.

My invention consists of a frame which is composed of two flat plates A, B, and is secured by bolts or screws passing through said Said bolts also hold in position the heels of the oar pivots, at the same time separate plates A, B, to allow for the operation of the segmental gears L, which are secured to and form part of the oars. t

Secured to the top of the plates A are two posts K, K, for supporting the feathering mechanism. Mounted on these posts are two sector gears H, H, having their rear ends reduced and slotted for the reception of the feathering mechanism, which will be hereinafter more fully described. The segmental gears are secured to posts K, K, by means of a plate I.

The handle C shown partly in section in Fig. 2- is mounted on a pivotal bearing and securely held in position by means of a screw, the screw engaging a recess in the pivotal bearing, thus allowing the handle to have a rotary motion. The opposite end D of theoar is also provided with a pivotal bearing similar to the one at C, for securing the oar shaft D, with its accompanying blade. Secured to and forming a part of said handle C, and oar shaft D, are brackets which have extensions or pins F, extending over the plates Aland B, at right angles to the oar shaft.

The pins F, extend through links Gr, pivoted in the slots in the reduced portion of the segmental gear Il', as is clearly shown in Fig. 4.

The oar frame is mounted ona hinge by means of a pin M. The bottom of the hinge is provided with a pin orlug N, being adapted to iit in any square or oblong oar lock seat, and having a hole in its lower end whereby it may be fastened securely by a string or any other suitable device as oar locks are ordinarily fastened thus enabling the oarsman to remove it at pleasure.

In Fig. 6- it will be noticed that the arm of the sector which terminates in a tube wherein the handle C, and blade shaft D, may be inserted. After the blade or shaft has been inserted the handle carrying the pin F can be securely fastened in its proper place by screws. The screw O, projects partly through the tube and into a recess formed into the blade or handle.

The operation of my device is as follows: The oarsman sits with his face to the bow, manipulating the oars in ordinary manner, at the same time having the advantage of seeing his course. The power is communicated through the medium of the gearing L, L, to the oar shaftD, from the handle C. As the oarsman makes a return stroke he feathers the oar by turning the handle C, as in feathering an ordinary oar, thereby movingthe pin F in the pivotal link G, causing the saineto tilt-H shown in Fig. 4.-as it moves the sector gear, thus communicating the same motion to the oar shaft D.

In constructing my improved oar great libertyzcan be used in the selection of material.

I propose to use wood for the handle proper,

oar blade and shaft, while the other parts can IOO having slotted reduced portions and the brackets at'the respective inner ends of the handle and oar blade shaft working loosely I5 in the slots, whereby the oar may be feathered substantially as specified.

In testimony whereof I affix my signature be made of aluminium, brass, malleable iron or steel, without departing from the spirit of my invention.

Having described my invention, that which 5 I claim as new, and desire to secure by Letters I Patent, is-

frame carrying the pivoted intergearing segments, the oar handle and oar blade pivoted 1o respectively to pintles forming part thereof, the intergearing segments pivoted above the before mentioned segments to the frame and REINHOLD H. PAAR.
