Larsen, Seattle, Wash. Application January 24, 1945, Serial No. 574,255 1 Claim. (or. 9--2s) 1 ‘ 2 casting or the like, having a ?at base portiony20 that is upwardly thickened, as at 22, between its ends, that is provided with a transversely dis posed slotway. This slotway is of inverted T form in cross-section and opens through the top side of the thickened portion 22, with its outer a small boat, such as a rowboat, in lieu of usual end closed and its inner end opening through socket block to receive the thole of the ordinary the inner side of the mounting. The shank M, type of socket rowlock, the mounting being of the ring I0, is ?attened, as at I6, at opposite adapted for securement by screws in a manner to eliminate any and all need for reinforcement 10 points on its periphery, for sliding engagement in the upper narrower portion 24, of the slotway, of the gunwale structure, or the use of ?ller This invention appertains to improvements in car or rowlocks generally, and has for its primary object to provide an efficient type of swivel mounting for the same, which is adapted to be fastened directly on the edge of the gunwale of blocks in such structure. Another object of the invention is to provide which terminates at its outer end in a circular opening 26, to permit of the required turning ' movements of the shank l4 and, consequently, of greatly facilitates the “laying-in” or “boating” of 15 the ring l0, correspondingly with rowing mo tions of the oar, while the head I8 is of a diam the cars, without requiring the lifting of the cars eter only slightly less than the width of the lower from the locks in order to-separate the latter from portion 28, of the slotway, to provide a clearance the mounting. sufficient to permit of its ready engagement in With these and other objects and advantages in view, the invention resides in the certain. new 20 and disengagement from the latter. The ends of the base 20 are each provided with pairs of coun and useful combination, construction, and ar ter-sunk apertures to receive fastening 30, such rangement of parts, as will be hereinafter more a rowlock and a swivel mounting therefor, which fully described, set forth in the appended claim, and illustrated in the accompanying drawing, in which: 25 Figure l is a top plan view ofthe improved rowlock, including a portion of the loom of an oar and the leather thereof, in accordance with the invention; Figure 2 is an elevation of the inner side of 30 the structure of Figure 1; Figure 3 is an elevation taken at right angles to that of Figure 2; Figure 4 is a top plan view of the swivel mount 35 ing per se; and Figure 5 is a top plan view of the rowlock per se. Referring to the drawing in detail, the row lock, as it is exempli?ed therein, is comprised essentially of an upright ring [0, to be engaged 40 on the loom A of an oar, an annular supporting shoulder l2 surrounding the upper end of a rela tively short, substantially cylindrical, shank It, which is provided with a circular head 18 on its as screws or the like, and a like aperture may be provided in the base, at its center, to receive an additional fastening 32; access being had to the latter through the circular opening 26. In use, with the rowlocks secured in place on the gunwales at opposite sides of a small boat; the ring ll] of each rowlock will be engaged on the loom A, from the handle end (not shown) of an oar and, thereafter, the leather cuff B is secured on the loom and engaged through the ring, with the “preventer” C, at the inner end of the cuff, abutted against the inner side of the ring. In order to “lay-in” or "boat” the oars, bladed ends (not shown) thereof are swung in wardly of the sides of the boat to place the oars in fore and aft positions, when inward pulls on the loom-s will withdraw the headed shanks from the slotways in, the base 20, allowing the cars to be layed in positions of readiness as is customary. As shown by the broken line ID’, on Figures 1, 3 and 5, the ring I0 is made substantially oval in cross-section so that usual rowing motions of lower end. The loom A is preferably provided 45 the oar A are permitted, even though the cuff B has a substantially snug ?t in the open center with a leather cuff B, to protect it against rub of the ring, and these motions are further facili bing wear against the ring and to more or less tated by the compressible nature of the material muf?e the sound incident to rowing movements, from which the cup is made. and a preventer, in the form of an annular ?ange From this description of thelrowlock, and the C at the inner end of the cuff, to engage the manner of its use, it will be obvious that it may inner side of the ring In, to prevent unintended be conveniently and quickly fastened in position disengagement of the car from the latter and on the gunwale of a rowboat, or other small its possible loss outboard of the boat. craft, by screws, or on the clamp rail D (Figures The rowlock, as thus constructed, is supported in a swivel mounting, which is in the form of a 55 2 and 3), in which case, bolts 30' may be sub ‘ ‘ 4 2,405,659 3 4 stituted for the screws. By this manner of fas tening, it will be evident that there is no need ring having a substantially cylindrical shank, an to weaken the gunwale structure by boring holes of the shank, and a circular head at the lower end of the shank, said slotway being of inverted T-form, the upper narrower portion of said slot way terminating at its outer end in a circular opening, said shank being ?attened at opposite points on its periphery to allow for its passage therein to form sockets to receive tholepins or the like, nor is it necessary that ?ller blocks or any reinforcement be employed in such struc ture, in order to correctly and properly mount the rowlocks in place. annular supporting shoulder at the upper end What I claim is: p g inwardly of the upper narrower portion of said In combination, a'ring rowlock and a swivel 10 slotway and into said circular opening for sub mounting therefor. said mounting being adapted sequent turning movements in the latter during to be fastened on the edge of the gunwale of a , rowing motions of the oar. rowboat or the like and having a slotway open ing through its top and inner side, and said - ' HARRY V.
