SPECIFICATION forming part of Lettersratent No. 772,264, dated otober 11, 1904. Application led December 24, 1903. 4 Serial No. 186,417. (No model.)

To all whom, t may 0071.067471.: v

Be it known that I, HENRY W. WHEELER, a citizen of the United States, residing at Syracuse, in the county of Onondaga andv Stateof New York, have invented aD new and useful Improvement in Oar-Locks, of which the following is a speciiication.

This invention relates to oar-locks, and has for its object a lock of this character which will be simple and light in construction and at the same time strong enough to stand any reasonable strain that may be put upon it.

A further object is a lock adapted for feathering and practically noiseless in its operation.

My invention consists in the novel features of construction and combination of parts hereinafter described, particularly pointed out in the claim, and shown in the accompanying drawings, in which- .Y l

Figure 1 is a perspective view of my device, showing same applied to a boat. Fig. 2 is a detail sectional view taken transversely through the gunwale of the boat, the tholepin being shown partly in elevation and a portion of the oar being shown in elevation. Fig. 3 is a section on the irregular line 3 3 of Fig. 2. Figs. 4 and 5 are end elevations of slightlymodified forms of locks.

In applying this device the gunwale of the boat is cut away, as shown at A in Figs. l, 2, and 8, and in this cut-out portion is inserted a plate B of some thickness, flanged at its upper end, the flanges B extending a considerable distance longitudinally, and these iianges are held in place on the gunwale by suitable bolts and nuts, as shown in Figs. land 3. The plate B has a vertical cylindrical slot B2, formed in it midway its ends, the slot being upwardly and downwardly open, and at its lower end it is .closed by a plate B3, fastened by screws to the lower end of the plate B. The slot B2 is enlarged at each end, so that a cup-like receptacle is provided at each end of the slot for the antifriction-balls B4, the balls at the lower end resting on the plate B3. An aperture is formed in the front of the plate B, which intersects the slot or bore B2. To the front of the plate B is secured an inverted triangular-shaped spring B5, secured at its tion of the non-reduced part of the thole-pin turning on the upper set of balls B4. An annular groove C is formed around the reduced portion of the thole-pin, the groove alining with the aperture in the plate and the pin BG extending into said groove. To retract the pin by lifting the spring-plate B5 outward, a ring B7 is secured to the lower end or apex of the spring. The upper portion of the tholepin is enlarged into a head C2, and formed on this head intermediate its ends are a pair of lugs C3, transversely perforatedj A cylindrical sleeve D is slightly enlarged or flared and open at each end. Intermediate its ends the sleeve carries three depending lugs D', arranged in alinement and transverse to the bore of the sleeve. These lugs are perforated to aline with the perforations in the lugs C3,

the central lug D' fitting between the lugs C3.'

These two sets of lugs are pivotally connected by a suitable bolt and form a compact and durable knuckle-joint allowing a swinging vertical movement of thesleeve ends. To the rounded portion of the oar which is to be held in the sleeve D is secured a second sleeve E, which lits the oar snugly and is held against longitudinal movement on the oar by suitable screws countersunl; in the sleeve E. This sleeve is longer than the sleeve D and is exteriorly threaded adjacent each end, the intermediate portion being smooth and adapted to rotate loosely within 4the sleeve D. To prevent longitudinal movement of the-sleeve E in the sleeve D and consequent sliding of the oar with reference to the sleeve D, jamnuts F are threaded on each end of the sleeve E, and washers F are also arranged on .the sleeve E and fit between the ends of the sleeve D and the jam-nuts F. These sleeves are slightly beveled or curved on their inner face and rest within the enlarged portions of the sleeve D.

Suitable antirictionballs G are arranged in each end of the sleeve D and are held in place by the 'washers F.

In Fig. 4: I have shown a form of sleeve H adapted for use with a squared oar. This sleeve H has the three depending lugs H', corresponding With the lugs D of the sleeve D. The lug H is formed in two sections, the main section having outwardly extending side flanges H2, and the other section consists of a plate H3, which rests on and is bolted to these flanges. In the remaining Fig. 5 I have shown a simple form of sleeve J, adapted for use with a round oar. This sleeve is cylindrical in form and is longitudinally divided into two halves, each being longitudinally flanged on each side and the ianges bolted together. It is also provided with the depending lugs, and both the sleeves H and J are used in connection with the plate B and the thole-pin C.

It will be obvious from the above that I have an oar-lock that will permit feathering of the oar, vertical movement of the oar while at any angle to the gunwale, and also by rotation of the thole-pin in the bore B2 the required horizontal sweep of the oar, and, further, that such movements will not cause any wear or tear on the part of the oar locked to the gunwale. To remove the oar from the boat or from its position on the gunwale, it is only necessary to pull'on the ring B7 and the pin BG will be drawn outward, disengaging the groove C of the thole-pin, and the pin may be lifted from the bore of the plate B2, the said bore practically forming asocliet for the thole-pin.

The oar K may be round or squared, depending on the form of sleeve with which it is used; but in' no case is it necessary to cut away thev oar, and thus reduce its diameter and weaken it, in order to secure the sleeve to it.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination with an oar, of a sleeve secured thereto and threaded adjacent each end, a second shorter sleeve adapted to receive the first-mentioned sleeve, said second sleeve having depending lugs formed integral with it, a thole-pin having ahead portion carrying lugs adapted to lit between the lugs of the second-mentioned sleeve, a bolt passing transversely through said lugs, washers adapted to lit over the first-mentioned sleeve and to close the ends of the second sleeve, jam-nuts adapt- .ed to be threaded on the irst-mentioned sleeve and bear on the washers, and means for securing the thole-pin to the gunwale of the boat.
