FISHING-ROD JOINT.

SPEOIFICATIN form-ing part of Letters Patent No. 537,088, dated April 9, 1895.

Application filed J une 13, 1894- To a/ZZ whom it may concern.:

Be it known that I, GEORGE I. VARNEY, a citizen of the United States, residing at Poughkeepsie, in the county of Dutchess and State of New York, have invented a new and useful Fishing-Rod Joint, of which the following is a specification.

This invention relates to improvements in joints of fishing-rods, and has especial reference to the improvement of that class of joints employed between the ends of that class of rods formed of split bamboo; the longitudinal sections of which are glued together.

My invention has two'primary objects in View, namely: the prese'rvationnof the glued sections and the avoidance of the same becoming soaked with water and thereby caused to'separate; and the prevention of weakness at the points of juncture of the sections of the rod and the metal ferrules employed in the joint. Great difficulty has existed in the manufacture of this class of rods, in the pres.- ervation and proper protection of the glueconnected longitudinal rod-sections, and in all the better classes of light rods composed of a series of jointed sections, in the strengththe metal ferrules and the wood; and such weakness has been caused by various reasons, the primary one of which has been that the ends of the sections, which are usually polygonal in cross-section, have been reduced to a cylindrical body in cross-section, such reduction resulting in the weakening thereof, and hence strain being brought upon the flexible rod-section, is immediately transmitted to the rigid metal ferrule and the result is that a break or fracture takes place at the juncture of the metal and the wood. I have found by experience that if the reduction of the sections couldv be avoided at the point of junction between the ferrule and rod, this weakening can be avoided, and the strain instead of being abruply transmitted from theresilient rod-section to the ferrule, would be thereby gradually transmitted over a considerable portion of the surface of the red-section, and at the same time splitting the end of the ferrule so as to form a series of resilient tongues,

whereby not only are these points greatly strengthened but also the graceful outline of serial No. 514,453. (No man.)

the rod as a whole, when yielding to pressure or strain, preserved.

I accomplish the objects heretofore set forth, from which accrue the enumeratedv advantages, in a manner hereinafter specified and particularly pointed out in the claims.

Referring to the drawings:-Figure l isa side elevation of a joint between two bamboo sections, constructed in accordance with my invention.

detail in perspective of one of the ferrules.

Fig. 4 is atransverse section through the rodsection andthe yielding end of the metal ferrule. Fig. 5 is a detail in perspective of the end of the rodisection, the ferrule removed. Fig; 6 is a longitudinal section of a joint constructed in accordance with my invention, but adapted for ordinary light rods, other than split bamboo,

Like numerals of reference indicate like parts in all the figures of the drawings.

Referring particularly to Figs. l to 5, inclusive, 1 designates two split bamboo rod sections, which at their inner extremities are reduced to form cylindricalends 2, and above the same merge very gradually into the polygonal portions, said gradual merging being obtained by a slight scraping away or removal of the angles of the section, as indicated at 3.

ing said ferrule upon asuitably shaped mandrel. The edges of the inner reduced end arenow split between the angles or corners, as indicated at 7, so that a series of angular thin spring-tongues 8 is formed. The ends of the rod-sections are now inserted into their ferrules thus constructed, and driven tightly to position; and when in position it will be The Fig. 2 is a Vertical longitudinal l i senese seen that the cylindrical portions ofthe rod-sections fit the reduced cylindrical portions 5 of the ferrules, While the 'somewhat tapered and enlarged cylindrical portions 3 of the rod-sections fit the enlarged cylindrical portions 4 of the ferr'ules. It will also be seen that inasmuch as the ends ot the ferrules have been made polygonal and composed of a series of angularl spring-tongues agreeing in number with the angles of the rod-sections, each angle or corner of said rod-sections will be embraced snugly by one of the thin angu lar spring-tongues.

9 designates a cylindrical sleeve, open throughout its length, and a little greater in length than the combined length of the two reduced cylindrical portions or ends 5 of the adjacent ferrules, and of an internal diameter adapting it to snugly receive said reduced ends 5 of the ferrules, in which position the ends of the ferrules very nearly though do not quite contact.

By the above construction it will be seen that the glue-joints at the ends of the rodsections are thoroughly and efficiently protected from and preserved against the admission of any moisture whatever and hence remain intact for a greater period of time and are not liable or in danger of splitting. It will also be evident that strain upon the rodsections is gradually diffused and extended to the yielding tapered annular springtongnes S, and thus the Stress being diffusori and spread over a greater surface of the rodsection, the liability of a fracture occurring at the juncture of the rod-section and ferrule, is avoided; and as a matter of fact the joints are thereby rendered the strongest portions of the entire rod. l

In Fig. 6, 10 designates a rod-section, polygonal in cross-section, and formed of suit able light wood` other than split bamboo. The end of the section like that of the section 1, is tapered as at 11, though the taper extends from the beginning thereof to the end, and is therefore considerably longer than that of the section 1. 2 designates a cylindrical ferrule, the inner end of which is finished precisely like the ferrule described in connection with Fig. l, in that it is tapered as at. 13, to a thin inner edge; afterward made polygonal in cross-section, and split to form the series of angular tongues le. When introduced over the end of the section 10, the angular tongues each embrace an angle of the section; and the reduced or cylindrical portion of the section fits snugly in the body of the ferrnle. The ferrule is open throughout its length, and at its outer end is provided with a milled boss 15, which corre spends with a similar boss 1G, formed at the corresponding end of the sleeve 9, illustrated in Fig. 1. The outer end of the ferrule receives the inner reduced cylindrical end 5 of a ferrule constructed after that shown in Fig. 1, so that as will be evident, theonly change in the modification consists in omitting' the reduced portion 5 of one ferrule, and continuing the enlarged cylindrical portion 4 in lieu thereof. This modification is as before stated, preferably used onlyin connection with rods formed of other than split bamboo, and the reason of this is that such rods employ no glue joints and hence do not require the eX- treme care and avoidance of moisture.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that I efficiently accomplish in a simple manner the objects of the invention, minutelyenumerated and detailed at the beginning of this specification; and which it would seem -unnecessary to repeat.

,Having described my invention, what I claim is 1. The combination with a polygonal rodsection, one end of which is slightly reduced and gradually merged into cylindrical form, of a metal ferrule' fitting the cylindrical portion and having its inner end bent into polygonal form to embrace and correspond with the polygonal-shape of the rod-section above its reduced portion, and provided between its angles with splits forming a series of intermediate angular spriug-tongues for embracing and conforming to the configuration of the angles of the rod-sections and 'extending along the same, substantially as specified.

2. The combination with a polygonal rodsection, one end of which is slightly reduced and gradually merged into cylindrical forni, of a metal ferrule fitting the cylindrical pon tion and having its inner end tapered and thinned, bent into polygonal form in crosssection, and split between its angles, thereby forming a series of intermediate springtongnes, having angnlarly-disposed sides embracing and extending along the angles of the rod-section, substantially as specified.

3. The combination with the opposite polygonal rod-sections, of the opposite t'errules each consisting of an outer closed end, a reduced cylindrical portion for receiving the cylindri cal end of the sections, and beyond the same a slightly enlarged cylindrical portion for receiving the gradually tapered portions of the sections, said ferrules having their inner extremities exteriorly reduced and tapered to a thin edge, polygonally-shaped in cross-section and split intermediate its angles, forming intermediate spring-tongues, having angularly-dsposed sides fitting over and extending along the angles of the sections, and the cylindrical open-ended sleeve receiving the ends of the ferrules,substantially as specitied.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
