BY .Dqmli I momsm Patented Apr. 24, 1951 OFFICE SCULLING OARLOCK AND MOUNTING CLAMP THEREFOR Carl M. Vick, Jacksonville, Fla. Application October 15, 1948, Serial No. 54,690
This invention relates to an improved form 4 Claims. (01. 9-26) and construction of sculling oarlock and mounting clamp therefor.
An object of the invention is to, provide an improved portable sculling oarlock and attaching and supporting clamp therefor which may be' readily attached to the stern or transom of a boat when the same is to be used, and which may be conveniently carried in a tackle box at other times when the sculling oarlock is not being used.
Another object of the invention is to provide an improved portable sculling oarlock and and mounting clamp or bracket therefor, which skill in sculling a boat may be acquired in a very short period of time.
A further object of the invention is to provide an improved sculling oarlock which will positively .clamp an oar within the same while being used,
and which may be readily and instantly released when it is desired to use the oar for pushing a boat or, for reversing the same.
A still further object of the invention is to provide an improved form of sculling oarlock and mounting clamp therefor which may be instantly attached to the transom of a boat for sculling the same with one hand, while using the other hand for fishing, trolling, etc.
Another object of the invention is to provide an improved form and construction of portable sculling oarlock and mounting clamp therefor, which will be highly efiicient in operation, and relatively inexpensive to manufacture and produce.
-Another object of the invention is to provide an improved portable mounting clamp for an ordinary or conventional type of oarlock which the skilled operator may use in sculling.
Another object of the invention is to provide.
an improved portable mounting clamp for an ordinary or conventional type of oarlock which may be mounted on the sides of gunwales of a boat for use in rowing where oarlock ferrules are not already provided.
Other objects will appear as the description proceeds.

2 Like characters of reference are used throughout the followingspecification and the accompanying drawings to designatecorresponding parts.
In carrying out the invention, there is devised and provided an improved form and construction of sculling oarlock and mounting clamp therefor including an inverted U-shape clamp body I adapted to be fitted over the top of a boat transom 2, one dependin arm of said clamp body I supporting two spaced clamping screws 3 having swivel heads 4 adapted to engage the A vertically disposed tubular supporting socket 5 is welded or formed at 6 to the outer surface of the other depending arm of the clamp body I for rotatably supporting the sculling oarlock, generally designated by the reference numeral 1.
The sculling oarlock 1 includes a depending shank portion 8 formed with an upstanding transversely apertured ear 9, and with the oppositely disposed transversely extending lugs or cars II]. A rearwardly or outwardly extending lug H is formed integrally with the shank portion 8, and is provided with a screw threaded vertical aperture (not shown) through which the adjusting screw I2 is adapted to extend, said screw being formed with a kerf I3 in itslower end.
The sculling oarlock 1 also comprises the outer ring portion M which is formed with the spaced depending ears [5 formed with transversely aligned apertures, and when said ears [5 are disposed at the'opposite sides of the ear 9, a pivot pin l6 may be placed transversely through the aligned apertures. A rearwardly or outwardly extending adjusting lip or ear I1 is formed integrally with the ears l5, and will be positively engaged by the upper end of the adjusting screw I2 for selectively varying the angle at which the oarlock I will be used.
Oppositely extending guide lugs IE will be formed on edges of the outer ring l4, and will terminate above the inner surface of said ring. Oppositely disposed pairs of guide lugs or ears I9 and 20 will be secured to the edges of the ring 14 at points. laterally ofthe arcuate guide slot 2| formed in the upper portion of the ring [4,
' and through which the depending threaded l9 and 20 may be mounted on either the inner ring 23 or the outer ring 14 at the option of the manufacturer. An arcuate clamping arm 25 will be supported upon the inner end of the clamping screw 22 for clamping engagement with an oar (not shown) when inserted through the said inner ring 23. An elongated angle oar support 26 will be disposed within the lower portionf "the inner ring 23 for supporting the lower surface of an oar handleand' to provide for self alignment of the oar While the clamping arm 25 looks against the upper surface of said oar. Since the dependingguidelugs Sand 20 and the guide lugs [8 permit rotation of ,the inner ring 23 within the outer ring it without longitudinal play, the oar will be secu'red'iin the oarlock 1 and movable for sculling, but said oar will be positively retained within the 'oarlock at other times unless the shank portion! 8110f the.
oarlock is bodily lifted from the tubular support" ing-socket 5 -fo r, pus hing=or poling of the boat.
-'-From ;the foregoingdescription, it will be apparent that the improved sculling-oarlock and mounting clamp therefor may be readily attached -to.the transom 2 of a boat when it is to be used, and may be readily removed and stored in a tackle box crother suitable storage place when not in 1 use.
-While 'the preferred embodiment-of the instant invention has been illustrated and de :scribed, itwillbe understoodthat it is notintended to-limitthe scope of the invention there- "to, as many minorchanges in detail of construc- "tionmay be resorted to without departure from ithe spirit of the invention.
