OAR-LOCK.

Application filed September 5,

Specification of Letters Patent.

Patented Feb. 27, 1906.

1905. Serial No. 277,002.

To all whom, it may concern:

Be it known that I, ANDREW ANDERSON, a citizen of the United States, and a resident of Mason, in the county of Bayfield and State of Wisconsin, have invented a new and Imroved Oar-Lock, of which the following is a iull, clear, and exact description.

The purpose of the invention is to provide a simple and effective oar-lock adapted for permanent attachment to an oar and yet have removable connection with the gunwale, the said oar-lock being so constructed as to enable the oarsman to have full control over the oar and to operate it with less fatigue' than ordinarily.

Another purpose of the invention is to provide a construction of oar-lock which will admit of the oar having three free movementsd a forward-and-rearward movement, an upand-down movement, and a rotary movement.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference ures.

Figure 1 is a perspective view of the device.

oar appearing in plan view 3 and Fig. 3 is a vertical section taken practically on the lines 3 3 of Fig. 2.

A represents a portion of the gunwale of a boat, and B the oar. The gunwale is provided with a vertical bore 10, as is shown in Fig. 3, and a socket-plate .11 is secured to the upper face of the gunwale at the said bore 10, as is also shown in Fig. 3. This socket-plate 1 1 is provided with an opening 12, which registers with the bore 10 and is of the same diameter as the bore, and the said socketplate is Jfurther provided with a collar 13 around the opening 127 the inner diameter of the-said collar being greater than the diameter of the opening 12, forming thereby an inner shoulder 14 at the bottom portion of the said collar, as is also shown in Fig. 3.

The oar-lock proper consists of a standardsection O and an oar-carrying section C. In the construction ofthe standard-section C an upper horizontal bearing 15 is provided, and a post 16, circular in cross-section, extends This post 16 i has an intermediate reduced portion 17, forming a shoulder 18, which shoulder 18 rests upon the upper edge of the collar 13 when the standard O is in position on the boat. The intermediate reduced portion 17 oi the said stud or post 16 fits loosely in the collar 13, and iinally the lower portion 18:1L of the said stud is Jfurther reduced in diameter, forming an upper shoulder 18h, which rests upon the shoulder 14 on the collar 13, while the lower reduced portion 18a of the stud 16 passes throughv the opening 12 in the socket-plate 1 1 into the bore 10 in the gunwale, as is shown in Fig. 3.

The oar-carrying section O consists of a split sleeve D, as is shown in Figs. 2 and 3, the said sleeve being in two longitudinal sections, and these sections are adapted to be placed on the oar B and attached to said oar by screws or their equivalents, as is also shown in Figs. 2 and 3. Near one end of the said sleeve D an exterior annular flange 21 is formed.

The sleeve D is loosely passed through an eye or a band 22, which eye or band 22 engages with the inner side face of the flange 21, as is shown in Fig. 2, and said ring or band 22 is provided with a horizontal cylindrical extension 22a, threaded at its outer end, and said extension is adapted to turn loosely in the bearing 15 of the standard-section O. The oar-carrying section is held in horizontal position and in the bearing 15 by placing a washer 23 on the threaded end portion of the said extension and screwing a nut 24 on the same portion of the extension to an engagement with the'washer, the extension having a square shoulder and the washer having a square opening to it said shoulder.

After the ring or band 22 has been placed in position on the sleeve D a collar 25 is slipped over the sleeve at the end opposite that at which the ilange 21 is located, and this collar 25 is secured to the sleeve and to the oar in any desired manner-for example, by screws, as shown.

When the oar-lock is'in position in the gunwale of the boat, as is shown in Figs. 1 and 3, it is evident that the standard-section will turn in the gunwale, enabling the oar to be carried toward the bow or toward the stern, and that the oar can be raised and lowered, the carrying-section for the oar turning in the standard-section. Furthermore, it is obvious that the oar can be bodily turned in its carrying-section C', so that every move- IOO IIO

ment of an oar necessary for the propulsion of a boat is obtainable, and the oar can be so balanced in the device as to render the work of rowing less fatiguing than ordinary.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In an oar-lock, a socket-plate adapted for attachment to the gunwale of a boat and having an opening therein arranged to register' with a bore in the gunwale, a collar formed around said opening in the socketplate, the interior diameter oi the collar being greater than that of the said opening forming an inner shoulder at the bottom of the collar, a standard-section having a bearing at its upper end, a stud extending' downward from said bearing, the stud being reduced in diameter intermediate of its ends forming a shoulder adapted to rest on the upper edge of said collar, the said intermediate portion fitting loosely in the collar, the lower portion of the stud being further reduced in diameter forming a shoulder adapted to rest on the inner shoulder at the bottom portion of the collar, the lower reduced portion of the stud extending through the opening in the socket-plate into the bore in the gunwale, and an oar-carrying section mounted to turn in the bearing of the stand ard-section, the said oar-carrying section being provided with a ring member in which the oar is adapted to turn.

2. In an oar-lock, a standard-section having a bearing at its upper end, the lower portion of the standard-section being fitted to turn in the gunwale of the boat, and an oarcarrying section consisting of a ring member having a horizontal cylindrical extension mounted to turn in the bearing of the standard-section, a split sleeve comprising two longitudinal sections secured to the oar, and passing loosely through said ring member, the split sleeve having an annular flange at one end, and a collar removably secured to the opposite end of the split sleeve, the said ring member being located between the said collar and the flange on the sleeve.

3. In an oar-lock, a standard-section having a horizontal bearing at its upper portion, a stud extending downward from the bearing and adapted to turn in the gunwale of a boat, an oar-carrying section comprising a ring member and a horizontal extension from the ring member, the said extension bein mounted to turn in the bearing of the standard-section and having its outer end threaded, devices engaging the threaded end of the extension to hold the extension in position in the bearing, a bearing-sleeve secured to an oar and mounted to turn loosely in the said ring member, and means for preventing the bearing-sleeve from moving longitudinally in the ring member.

4. In an oar-lock, the combination with a socket-plate having an opening therein, a collar formed around the said opening, the interior diameter of said collar being greater than that of the said opening, of a standardsection, comprising an upper horizontal bearing, a stud extending down from the said bearing, reduced in diameter intermediate of its ends and at its lower end, forming an upper portion which rests upon the said collar and a lower portion which passes through the opening in the socket-plate, an oar-carrying section consisting of a ring member having a horizontal cylindrical extension loosely mounted in the bearing of the standard-section, devices for preventing the extension from slipping from the said bearing, a split sleeve loosely passed through the said 4ring member, the split sleeve having an annular flange near one end, and a collar removably located at the opposite end of the said split sleeve, being adapted for attachment thereto, the said ring member being located between the said collar on the sleeve and. the flange of the sleeve.

In testimony whereof I have name to this specilication in the two subscribing witnesses.
