' BOW-FAGING oan.

Specification of Letters Patent. Patented J une 21, 1921.

Application filed. June :20, 1920. Serial No. 392,961.

its primary object the provision of an ad-' justa-bly mounted oar which may be operated from a sitting or standing position in a row boat or similar water craft. A further object of the invention is the provision of an adjustably mounted oar which may be moved in any position along the side or a boat and means to operate theoar while sitting facing the direction of travel. A still further object of the invention in this type of oars is the provision or" means to regulate the forward or backward sweep of the oar to suit the need and convenience of the operator.

With these objects in view and others which will develop as the nature of the invention is revealed in the detailed description which follows in connection with the drawing, all of which forms a part of this application, the preferred embodiment of the invention is shown in Figure 1, which is a plan 'view of the device showing in dotted lines the position of the car in its forward or backward position. s

Fig. 2 is a sectional view showing the device as attached to the side of a boat.

Fig. 3 is a view taken along the line 3-3 of Fig. 1.

Referring now to the drawing wherein like figures indicate like parts hereinafter mentioned, numeral 1 designates a row boat or similar craft to which my invention is applied and Qthe top ledge or side thereof. A flat plate 3 is secured to the side 2 by two L-shaped brackets 4 which have their arms 5 secured by thumb screws 6 to the inner side of the part 2. As will'be obvious, when the thumb screws are loosened the plate may be moved in any desired position alone the side of the boat. The plate 3 is provided with vertically extending notches or apertures 7 to receive the ends 8, U of two inwardly converging or outwardly diverging angular arms 9, 9 which support the oar. The end 8 of the arm 9' may be positioned in any one of a series of apertures 7 in the top of plate 3 to freelyswing therein. The vertically extending terminals 10 of the angular arms lie above the top ledge and receive cylindrical spools or sleeves 11 which support a short rod 12 therebetween. The rod 12 while shown extending between the spools 11 normally parallel with the plate 3 may move in angular relation thereto when the arms 9, '9 swing on their pivots as is obvious from Fig. 1. l l

Pivotally mounted to swing in a vertical plane about the rod 12 are two bowed shaped clamping members 13 which are provided at their ends with collars 14, 15 to receive the body portion 16 of the oar which has the usual hand grip portion 17 and flat blade 18. Threaded openings 19in the collars 1 1, 15 receive the usual thumb screws 20 whereby the oar may be longitudinally adjusted with respect to the screws or clamping members 20 or the angle of the blade 18 set at the convenience of the operator. The angular arms 9 supporting the connecting rod 12 and the screws or clamping members 20 are always maintained in therelation specified, being closer together at their inner ends than at their outer ends, but adjustable at their inner ends, so as to vary the sweep thereof, and when swung from the full to the dotted line position so thatwhen the operator moves the oar either forward or backward the clamping member will tend to move angularly toward the boat body as indicated in Fig. 2. By adjusting the arm 9 in the apertures 7 the forward or backward movement or arcuate sweep of the oar may be'regulated.

The operator first adjusts the car in the collars 15 15 at the same time angling or setting the blade 18 vertically. The arm 9' is then positioned in any one of the notches 7 thereby regulating the length of the forward or backward movement of the oar it being understood that to row a boat with any satisfaction it is necessary for the blade of the oar'to travel through a greater distance or are than the handle. By loosening the thumb screws 6, the clamping plate 3 may be moved to the desired position as will be apparent and by loosening the screws 20 and leaving the oars free to turn, the blades may be featherec.

While I have shown and described the preferred embodiment of my invention, I do not wish to be limited or restricted to the exact details of construction shown and retain the right to such changes and modifications as may fall within the scope of the matter now claimed. u 7

Having thus described my invention, 11 clai i. I

1. An oar lock, comprising a supporting member, means for securing said member to a boat, angular rods pivoted to the member, a rod connecting the outer ends of the angular rods and pivoted thereto, an oar support pivotally mounted on the said rod and means for adjustably securing an oar to said support.

QIAn oar lock, comprising an apertured plate provided with means for securing it to a boat, inwardly converging rods having their inner ends loosely mounted in the openings of the plate and having their outer ends terminating in upwardly projecting members, a rod provided with spools mounted on the said members of the rods, an oar support formed of two bow shaped members pivotally mounted on the said rod and provided with collars to receive the oar and with tumb screws for securing the oar in said collars.

3. Bow facing oars comprising rigid oars, and means for supporting the same at the sides of a 'boat for an arcuate sweeping movement with the blade ends moving in the same direction as the handle ends.

a. Bow facing oars comprising an articulated swinging frame support adapted for horizontally sweeping movement, means to detachably and adjustably mount the same in position, and vertically swinging oar holding means carried by said support.

Bow facing oars comprising an articulated swinging frame support adopted for horizontally sweeping movement, means to detachably and adjustably'mount the samein position, and vertically swinging oar holding means carried by said support, said oar holding means being provided with collars adapted toreceive the oar so as to extend across the frame support and permitting said ears to be feathered therein.

6. Bow facing oars, comprising a pair of spaced rods, means to pivotally support the same for horizontally swinging movement at their inner ends, a rigid member pivotally connecting the outer ends of the rods, the inner ends being closer together than the outer ends, and means for mounting an-oar on said rigid member.

7. Bow facing oars, comprising'a pair of spaced rods, means to pivotally support the same for horizontally swinging movement at their inner ends, a rigid member pivota-lly connecting the outer ends of the rods, the inner ends being closer together than the outer ends, and means forvarying the angular relation of the rods and an our support pivoted across the rigid member.

8. An oar lock comprising a clamping plate, brackets extending therefrom for supporting said plate to a body, pivotally mounted arms extending from said plate, a rod extending between said arms and parallel with said plate and an ear pivotal y supported by said rod.

9. An oar lock comprising a longitudinally adjustable clamping member, opposed extending arms supported thereby, a rod extending between said arms and pivotally supporting a second clamping member and an oar retained in said last mentioned clamping member.

10. An oar lock comprising a longitudinally adjustable clamping member, arms extending therefrom and pivotally.suppor'ed thereby, a rod between said arms, an oar clamping member pivotally supported thereby, means to move said oar forward or backward and means in said adjustable clamping member for regulating the forward and backward movement of said oar.

11. An oarlock comprising a longitudt nally adjustable clamping member, arms pivotally supported thereby, a rod between said arms pivotally supporting an ear clamping member, means to longitudinally adjust said ear with respect to said last mentioned clamping member and means to move said oar backward or forward.
