Description

Oct. 14, 1952 L. MAGDLTS BOW FAQIEG OAR Filed Marci; 15. 194s Inventor Louis Magdifs Patented Oct. 14, 1.952

I ari s, Chicago,- in. v I .1 w .Application March 15, is isj sefi inajslhzs A still further' object" of this nvention is-to provide an oar construction in which the blade of the car moves in the same relative direction as the push or pull exerted upon the car handle.

Another object of this invention is to provide an oar construction which will permit the rower to propel the boat in the direction in which he is facing so that he can always see where he is going and determine what obstacles are in the path of the boat.

A still further object of this invention is to provide an oar construction for moving a boat in a direction opposite to a pull on the oar comprising an elongated clamp member carried by the gunwale, a substantially U-shaped member pivotally secured at its hub portion to said clamp member, means for pivotally retaining an oar and a handle on the legs of said U-shaped memher, and a link terminally pivoted to the oar and handle.

These together with various ancillary objects and features of the invention which will later become apparent as the following description proceeds, are attained by the device, a preferred embodiment of which has been illustrated by way of example only in the accompanying drawings, wherein:

Figure 1 is a top plan view of the device entirely assembled;

Figure 2 is a sectional view taken substantially on the plane of section line 2--2 of Figure l; and

Figure 3 is a sectional view taken substantially on the plane of the section line 3-3 of Figure l. V

Specific reference is now made to the drawings. In the several views in the accompanying drawings and in the following specification reference characters indicate corresponding elements throughout.

Indicated generally at H) is a conventional rowboat having a gunwale I2 upon which the oar construction of the instant invention is appropriately supported. An elongated clamp member !4 is provided consisting of a longitudinally extending arcuated web or bar l6 carrying conventional C-clamps [8 at both ends thereof. It will be seen clearly in Figure 3 that the G-clamps engage the gunwale l2.

Secured to or integral with the ends of the 1 "Glaim (Cl. 9-25 web l 6adjacent the 'C-cla-rnps l8 is a pair fof bearings 2!]"for pivotally orrotatably' receiving the we b portion 22 of a U-shaped

member having legs

24 and 26 that'include'screw threads wan 30 at th'ejfree" extremities thereof. v

A" sleeve' 'mjember '32 is provided for receiving the; oar bladej'u'nit 34, thejlatter being retained upon'the sleeve by means of bolts 42 and't'fi i The sleeve member includes an intermediate embracing collar portion 38 having diametrically aligned apertures (not shown) which align with a bore in the oar blade unit and is rotatably received with the assembled oar blade unit on the upper extremity of the leg 30. One end of the sleeve member 32 is provided with an arcuated arm or ear 40. The purpose of this car will be described hereinafter.

A further sleeve member 44, similar in construction and design to the sleeve member 32 is provided for receiving the oar handle 46 which is retained therein by means of bolts 54 and 48. The sleeve member 44 includes an intermediate collar portion 50 also similar in construction and design to the collar portion 38 having diametrically aligned apertures (not shown) aligning with a bore in the handle 46 and is pivotally or rotatably received with the assembled oar handle on the extremity of the leg 24. At one end of the sleeve member 44 an apertured arm or ear 52 is provided also similar in construction and design to the ear 40.

As will be seen clearly in Figure l, the

cars

40 and 52 are apertured and oppositely disposed to receive

pivot pins

56 and 58 respectively extending through the apertured extremities of a link 60.

To pivotally retain the oar blade unit 34 and oar handle 46 upon the

legs

24 and 26 of the U-shaped member, a bar 62 is provided which is apertured at its extremities to receive the threaded

extremities

28 and 30 of the legs 24 and 25 respectively to overlie and abut the collar portions 38 and 59. Internally threaded

nuts

64 and 66 engage the

screw threads

28 and 30 to lockingly retain the bar 62 upon the

collar portions

38 and 50.

Thus it will be seen that the oar blade unit 34 and the car handle 46 are pivoted to each other and to the clamp M at 5B, 58 and at the positions of rotatable engagement of the collar portions 38 and as of the sleeve members with the legs 24 and Eli. In practical operation, when a pull is exerted upon the car handle 46 to the left on Figure l, the link 50 is pivoted to swing in an arc to the right of Figure 1 with the result that the oar blade unit 34 pivots to the left about the leg 26. Thus the car blade unit 34 moves through the water in the same direction as the pull exerted upon the oar handle 46 urging the boat It) in the direction in which the rower is facing if it is assumed that he has pulled the car handle 46 toward himself. A push on the oar handle 46 to the right on Figure 1 will similarly urge the oar blade unit 34 to the right also.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood however, that even.

though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention, what is claimedas new is:

A bow facing oar comprising a bracket. including a bar for mounting. on the gunwale of a boat, longitudinally spaced, aligned bearings on. said bar, a U-member, comprising threaded legs, having its bight portion journalled in said, bearings,

parallel sleeves journalled, at an intermediate point, on said legs, handle and blade oar sections fixed in said sleeves and projecting from opposite ends thereof, said legs passing diametrically through said sleeves and said oar sections, inwardly curved arms on the other ends of the sleeves, a link pivotally connected to said arms, a brace having its end portions journalled on the legs and resting on the sleeves, and retaining nuts, for said sleeves and said brace, threaded on said legs.
