FEATHERING PDDLE ATTACHMENT FOR SMALL BOATS.

Specification 01 Letters Patent.

Application tiled March 24,1905. Serial No. 807,878.

To all whom iii may concern.:

Be it known that l, lViLLiaii l'ticii'ains a citizen of the United States, and a resident of Portland, in the county of illultnonnih, Stale of Oregon, have invented a new and useful l Improvement in Fiaithering vPaddle Attachments for Small Boats, of which the following is a specification, reference being had to the accompgynyi'ng drawings as constituting a part thereof.

This invention has for its object to provide a Contrivance which is adapted to be readily attached to skids.` row boats and einer sin all vessels, for propelling the same by operating l my attachment in a similar manner as one would operate the oars of a boat; and 'tho paddlelbladc of my attachment is so contrived as to give an effective resistance on the forward stroke of my paddle, and to Vfeather on the water, to minimize the resistance on the back stroke of the paddle.

An incidental great advantage and feature Of my improvement, is that the person row inv is so'seated as to look ahead, instead ol' i puling backwards, as with the old-style oars.

To this end my invention is of the construction, and is operated as shown in the drawings, in which Figure l is a perspective elevation of a row boat with my attachment applied thereto, as in practice; Fig. 2 is an enlarged perspective detail showing a section of one side of a row boat having my invention applied thereto; Fig. 3 is a partial cross section illustratingT a modified construction ol the handlepart el' my attachment; Fig. 4 is a detail in perspective of one of the blades of my attachment,

of the boat; Fig. .5 is a detail in its general character corresponding with that ol' Fig. 4, excepting that, in this instance, the blade ol' my attachment is arranged for rowing the boat backwards. F ig. 6 is a cri'iss section corresponding to Fig. 5 and Fig. 7 is a cross section correspoi'iding with Fig. Ll.

The letters designate the parts described. To the sides of a boat are allixed frames 1:, ivotally supporting paddles c, operated b fiandles d as shown in Fig. l. "lhe eonstruction of the frames h is observable from Fig. 2. i The saine may be allixed in place by screwbolts b; and it comprises members e provided Awith hinge-pins e on which arc removablv 3' hinged the arms f of a rod 72.. On the guii- 'Wale 'of the boat are provided pins d oni handle. l made` with a bend p and has allixed thereto an angle iron q by rivets r.'

which are pivoled the handle bars d, connected by a link g/ with the upper of the arms f. On the shaft t is movably mounted a slitsleeve i arranged' to be claniped on the rod it by a thumb-screw '.lhe sleeve 'i is made with an integral, projecting bracket 7i', supporting in horizontal position a frame oomprising rml-members ym m. On the latter is hinged the blade 'n of the paddle, such blade being made willi arms n 11,, whereby the blade is hinged to the member in. '.lo the lower, inner corner of the blade n is allixed a ring e to which is attached a rope o', the end of which is fastened to the frame b as shown in Fig. 'lhc rope o is provided as a convenience to reverse, or turn-over the blade 1iy 'from its forwaril-stroke to its back-stroke position.

The paddle operating-mechanism is so a1'- ranged that the rowirr, sitting facing the boiv, pulls on the handles d to cause the paddles to make their forward-stroke, and pushes such handles to 'feather the blades back to their initial position. ln the forward stroke the i v blade n is arranged as shown in l* lgs. 4. and 7,

for example, that is to say, the blade being supported in its perpendicular position by resting on the frame in einbcr 'mf as shown in Fig. 7. vWhen so arranged, the blade n, dui'- ing its forward stroke will be positioned as shown in solid lines in Fig. 7, and while making its return stroke, will be lifted to a featlicring position, as indicated by the dotted outline in Fig. 7. Should. it be desired to propel the boat baclnvards, the blades 7iy would be turned over to the position shown thereof in Figs. 5 and 6, thus causing arms fa/ 7i. of blade n to bear up against theI underside of the frame member m while making the propelling` stroke with the paddle, and causing the blade to assume the position thereof shown iu the dotted outline in Fig. G, while making the return stroke. i

lin Fig. 3 l ha 'e shown a modification in the construction of the bearing of the paddlein this instance the handlebar p is 'lhe parts p g are perforated so as to be placed on the pivot pin d provided therefor on the gunwale of the boat. By the last described arrangement of the .handle-bars, the saine are aisedto a level which may be foundanorc convenient to the roiver.

il hen the boat is not 1n use, my paddlingattachment may be removed by lifting the same off the pivot-pins e', and laid away in the boat house.

The bracket c is movable on the rod 72 so as to be able to adjust the position or dip of the blades in the water relatively to the boat when carrying a load.

l claim:

1. The combination witlra boatfof a supporting frame aflir'ied to the side thereof, a rod vertically ivoted in such frame," a

-bracket projecting horizontally from said rod, Ia dependent blade hinged to such bracket, means restraining the blade to a perpendicular position on the forward stroke of the paddle7 and allowing the same to feather on the return stroke, a horizontal, pivoted handle-bar and means connecting the same with said pivoted rod, whereby the former is adapted to operate the paddle; the blade supporting-bracket being vertically movable on its su porting rod, so that the blade may be re atively adjusted to the depth of the boat in the water, and the parts being duplicated on both sides of the boat.

2. A paddle attachment for small boats, comprising a supporting frame adapted to be allixed to the side of a boat, a rod vertically pivoted in such frame, a bracket projecting horizontally from said rod, a dependent blade hinged to such bracket, means re-,

straining the blade to a perpendicular position on the forward stroke of the paddle and allowing thc sameto feather on the return stroke; a handle-bar and a pivoted support therefor adapted to be affixed on the gunwale of the boat, and means connecting said handle-bar with said pivoted rod, whereby the former is adapted to operate the paddle, the. blade-supporting bracket being adapted to be vertically movable on its supporting rod, so that the blade may be relatively adjusted to the depth of the boat in the water.

3. A paddle attachment for small boats, comprising a supporting frame, a rod made with arms f, f, vhereby the same is pivoted in vertical position in said frame, a bracket horizontally supported on such rod and comprising members fm, fm', a blade made wthright-angle arms n n, whereby such blade is hinged to the member m of the bracket, a handle-bar and a pivoted support therefor adapted to be afIiXed on the gunwale of the boat, and means connecting said handle bar with said pivoted rod, whereby the former is adapted to operate the paddle.
