This invention relates to a sculling oar adapted for use usually as the sole means of kpower for a fishing boat, and it is designed to enable the operator or fisherman to impart maximum speed with minimum energy while facing the prow of the boat, one hand being suilicient for operation thereof while the other hand is free for fishing purposes.

It is further aimed to provide a novel structure in whichthe oar may be attached to the boat at the stern, will seek a central longitudinal position, and is balancedY so as to normally remain in contact with the water and be in a position accessible for grasping and operation.

The more specic objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating y an operative embodiment.

In said drawing:

Cil

Figure 1 is a fragmentary elevation of a por- Y oar, partly broken away to disclose details, and

Figure 4 is a vertical section taken on the plane of line 4 4 of Figure 3.

Referring specifically to the drawing wherein like reference characters designate like or similar parts, I0 designates a conventional row boat or the like such as is used by shermen. In accordance with the invention, a suitable clamp I I is rigidly but detachably connected to the stern I2 of such boat, as by means of jaws I3 and screws I4.

Said clamp II mounts the sculling oar, generally designated I5. This oar has a central metallic section I6 in the rear end of which a wooden or other handle portion II is secured as by a tenon I8 entering a split socket I9 of section I6 with a removable bolt 20 passing through the handle and socket.

Said socket I9 is disposed at an angle to another socket 2| which is located at the other end of section I6 and similarly split, and engaged with the tenon of a sculling oar section 22 which may be of wood or any other 4material and through which socket 2| and tenon a bolt 23 removably passes. Sculling oar 22 may be of any desired shape and material and it is disposed at an angle to the handle portion I1, and the oar as a whole is balanced in the position shown in Figures l and s by using a weight at the maderas at ,24, whenA desired. I Y

The section I6 has practicallyuniversal joint connection to the lclamp II in that suchsection has a dependent at 25 pivoted by a pin 26 to a link 2l, which in turn is pivoted by a pin28dis posedat a right angle to the pin 26,l and mounted Y by ears 29 of bracket k34 on. the clamp* Il. Bracket 34 is swivellyconnected to the clamp II by a pin or bolt 35, which depends froml thel bracket and turnablyf'engages an opening 36 the intermediate," Ahorizontal position of `the clampll. ,1 I,

It will be realized that but one hand is necessary to operate the sculling oar disclosed, the same being moved in the water from side to side, as suggested in dotted lines in Figure 2. The extent of movement to either side may be limited by a flexible element 30 which is tethered to the handle Il and has a clasp 3l, which may be engaged with a staple or the equivalentl 32 fastened to a seat or other part 33 of the boat.

The movement of the oar blade in the water thwartwise while the blade is turned back and forth on its longitudinal axis, similar to the movement of a shs tail, is a conventional sculling stroke. However, in addition to the oar I5 being swingable in a horizontal plane, by the pin 35 turning in the opening 36, and in a vertical planeyby the oar I5 rocking on its pivot 26, the oar I5 is also mounted to rock on the pivot 28 to cause the oar to be oscillated or turned back and forth substantially on its longitudinal axis to changeithe pitch of the blade, as is required during the sculling stroke. This movement is accomplished by rocking the handle section Il on pivot 28 downwardly and toward thefdirection that the handle section is swinging. This can obviously be accomplished with much less effort than is required to twist the ordinary oar to execute the sculling stroke, as the element 30 is normally taut so that it will pull the handle I1 downwardly as the handle is moved to either side of its central position, and the pressure `exerted by the sculler will therefore cause the oar I5 to be rocked, as previously explained, on pivot 28.

It will be noted that when reeling in after releasing the oar, the latter remains in its center position due to the balancing thereof and its pivotal mounting, ready to resume operation. The structure will permit silent operation, is simple to attach to a boat, and may be manufactured in minimum lengths and weights.

Various changes may be resorted to provided end to provide means to limit the movement of.

the oar in both directions and to constrain the swinging movement of the oar to an arcuately shaped path the radius of whiclriisequal` tothe length of the flexible element.
