O G SIMPSON & R M MoPBBK BOW FACING OAR. v APPLIOATION FILED MAY 3 1904 UNITED. STATES PATENT OFFICE. ORA C. SIMPSON AND ROSS M. McPEEK, OF NEWTON, NEW JERSEY.
BOW-FACING OAR- i i Specification of Letters Patent.
Patented Aug. 1, 1905.
Application filed May 3, 1904:. Serial No. 206,258-
To all whom it may concern.-
Be it known that we, ORA' C. SIMPSON and Ross M. MOPEEK, citizens of the United States, and residents of Newton, in the county of Sussex and State of New Jersey, have invented certain new and useful Improvements in Bow-Facing Oars. of which the following is a specification.
This invention has reference to certain improvements in bow-facing oars; and it consists in the novel construction and combination of parts set forth and explained in the subsequentdetailed description and pointed out in the appended claim.
In the accompanying drawings, forming part of this specification, Figure 1 is an elevational view looking at the inner side of the parts forming the base of our improved oar-lock. Fig. 2 is an end view of the parts disclosed in Fig. 1. Fig. 3 is a plan view of the basecasting, the bearing-section being removed. Fig. 4 is a perspective view illustrating the manner in which the gear-sockets of the bowfacing oar are secured in position. Fig. 5 isa detail perspective view of an ordinary oar-lock the stem or pintle of which can be inserted in either of the top perforations of the lockbase when the parts of the bow-facing oar are not employed. A portion of an ear is repre- Tented in connection with said ordinary oarock.
Similar reference characters are employed to designate corresponding parts in the several figures of the drawings wherein they occur.
The main or body portion of the deviceis embodied in a casting A, comprising a lower vertical Web at, having a seris of perforations v a, by which it can be secured by screws externally against the g-unwale of a boat, such web terminating at its top in a horizontal offset or shoulder (4 which is to bear upon the gunWale-top, the end portions of said shoulder .-containing countersunk openings a for the location of screws to serve as additional means for securing the casting to the boat.
\ Above the shoulder a the casting A presents a vertical housing, which besides the flat horizontal top cf also comprises inner'horizgntalas well as vertical stiffening-sections a a Both the top and the horizontal stiffeningsection a contain openings 0: of comparatively liberal area and adapted for the reception of pins 1) b, integrally depending from a bearing-section B, including a base-plate b for bearing on the housing-top and a pair of cars 72 for receiving a horizontal pin 0, which passes through an appropriately-shaped metal block C, on which are pivotally mounted and secured the intermeshing gear-segments D D, integral with the sockets of the bow-facing sections. The pin 0 is retained in position by cotter-pins or keys 0.
When it is desired to discard the bow-facing' parts and adapt the device as an ordinary oar-lock, the bearing-sections B, together with the bow-facing parts supported thereby, are lifted from position, the stem or pintle e of a common form of oar-lock E, Fig. 5, being then inserted to revolubly bear in either pair of the vertically-alined openings a and the device thus rendered capable of service as an ordinary oar-lock.
From the foregoing description it will be appreciated that the device embodying our Having now described our invention, what we claim as new, and'desire to secure by Letters Patent, is 4 In an oar-lock device, the combination with a base-casting having a lower horizontal perforated part adapted to bear and be secured on the top of agunwale, said casting including a housing havingatop and horizontal Web, the latter in a lower plane, said top and web containing a plurality of alined perforations, a bearing-section provided with upper perforated ears and having a flat bottom part for resting on the housing-top, said section being equipped with depending pins for engaging within the perforations of the housing-top and web, and a block pivotally supported in the ears and carrying-intermeshing gear-segments and sockets for the oar-sections.
Signed at Newton, in the county of Sussex and State of New Jersey, this 16th day of April, A. D. 1904.
