IMPROVEMENT iNYJolNTED oAns.

The Schedule referred to in these Letters' PatentV and making pit of the same 4To 'all Iwhom it may concern:

Be it known that I, CHRISTIAN DANN, of La Grosse, in the county of La Grosse and State of Wisconsin, have invented a` new and improved Jointed Oar; and I'do hereby declare that the following is a full,

'.clear, and vexact description thereof, which will enable others skilled in the art to make and use the same,

. reference being had to the accompanying drawing forming part of 'this specification, in'whchv Figure 1 represents a perspective view ot' my i1nproved jointed-oar.

Figure 2 isa detail side view of the jointed part. A Similar letters of reference indicate corresponding parts. My invent-ion relates to jointedoars' which are 'operated by a person facing the bow; and -'It has for its object toldisp'ense with metal cogs,

iihich rattle, produce great friction, are heavy, expensive, and constantly acting to pull apartthe joint. For'this purpose I propose to combine, with the ordinary pivoted handle, blade, and swinging plate, a exiblecord, fastened to the rounded and .pivote'd ends of the handle 'and blade.

A B arethe two parts the 'oar,. being the handle and'B t-he blade.

These t-wo parts are, by means of pins wb, respectively pivoted to a plate, C, which, at-its ends, is pivoted into ears projecting 'from the gunwale of the boat. i

flhe contiguous or adjoining pivoted ends of the parts A B are connected with each other by means oi' a string or cord, c. Thus, it will'be perceived that the Aconstant; tendency of tbe joints will -be to come together, instead of being to separate; that the joint` works noiselessly; that the cord is readily'replaced in ease of accident or wear, and that the cost is but a small fraction of that of the cogged metal pinions. Having thus described my invention, i I claim as new and desire tosecnre byIJetters Patent- The combination, vwith a pivoted handle,blad,and plate, A B Q, of ,the flexible cord c, fastened to the rounded ends 4of the handle and blade, as and for the purpose' described. l

, CHRISTIAN DANN.
