PORTABLE OARLOCK Filed Deo. 4, 194e @gay Patented Feb. 8, A1949 UNITED STATES PATENT FFCE PORTABLE oARLocK Samuel A. Black, Chicago, Ill. Application December 4, 1946, Serial No. 713,962
The present invention relates to oarlock or rowlock structures and more particularly to a portable type of device.
VAmong the objects of the invention is to provide a novel oarlock or rowlock support structure which is readily selectively attached at any given point or locus of the gunwale of a boat, such as fishing boats or the like, to aiord lconvenient operation of the oar or oars at any chosen part of the boat and comprises relatively adjustable clamp parts or members adapted to be iitted to any selected portion of the gunwale, together with tightening elements for causing the clamp parts to be firmly attached to the gunwale, one of the clamp parts having rigidtherewith the oarlock or rowlock socket. which pivotally carries the oar saddle or strap.
Another object of the invention is to provide means for the 4clamp parts to be adjustable for clamping the gunwale both in width and height and adaptable to different sizes and shapes of gunwales, while using a single means of tightening the clamp parts for the coordinate clamping yin both ways of gunwales.
Other objects, capabilities, advantages, features, and the like are comprehended by the invention as will later appear, and as are inherently possessed by the invention.
Referring briefly to the drawings:
Fig, 1 is a perspective view of an embodiment constructed in accordance with the invention;
Fig. 2 is a top plan view thereof with a part of the gunwale of the boat;
Fig. 3 is a transverse sectional view'thereof taken in a plane represented by line 3 3 in Fig. 2 of the drawings; and,
Fig. 4 is a side view of the device.
Referring more in detail to the drawings, the embodiment chosen to illustrate the invention is shown as comprising an oarlock thole or socket i serving as a fulcrum for the o ar saddle or strap having a pin or pintle (not shown) rotative in the socket I. Rigid or integral with the socket I is a clamp member or part 2 of angle form comprising a plate part 3 adapted to overlie the gunwale of the boat, a flange part 4`adapted to Vabut the outer side of the gunwale and being preferably formed integral with the socket i. The plate part 3 has one or more slots 5 for the passage therethrough of clamping bolts 6 or other suitable securing elements. K
The device is adapted for attachment to the fg'unwaleof a boat comprising a gunwale runner 'I extending along the upper side portion 8 of the side 9 of the boat. Within the side Bof the boat:
areY xed upstan'dingm bracing ribs lil which are curved to follow thefcurvature of the body or hull of the boat, as shown in Fig. 3. To the upper end parts of these ribs Iii is nxed an inner gunwale part or brace runner IIV providing spaces IIJIl between the runners 'I and l i and between the ribs.
Upon the plate 3 is placed another clamp member or part I2 on the inner side of the gunwale and having a plate part I3 provided with one or more slots I4 in registry with slots 5 of the plate part 3 and for the passage therethrough of the bolts 5. The clamp member l2 also comprises a flange part I5 t0 be disposed laterally within the gunwale part I I, as shown in particular in Fig. 3.
Beneath the gunwale part or runner i I is placed l a third clamp member I6 having a lower plate I'I provided with one or more slots I8 in alinement with the slots 5 and I4 and for the passage of the bolts, the plate part I 'n' being adapted to be clamped to the underside of the gunwale part or runner II, as shown inV Fig. 3. The clamp member I6 also has upstanding flange parts or portions IS and 20 of which the flange part 2Q is interposed between the flange i5 of the upper clamp I2 and the `gunwale runner Il to be clamped therebetween, andthe iianges I9 are disposed outwardly of the flange I5 (see Fig. 3) to be clamped thereagainst. The lower clamp member I6 is relatively adjustable to the clamp member Il? depending upon the vertical dimension of the gunwale runner II, so that when the device is attached to the gunwale of the boat, the clamp member I5 will be clamped upwardly against the gunwale runner II while at the same time the upper clamp members 2 and I'2 are clamped to the upper part of the gunwale gen- I erally.
The bolts 6 extend upwardly through the slots I8, 5 and I4 and are provided with heads 2i' to abut the lower `side of the plate part il against the underside of the runner I I and with threaded upper ends 22 to which may be threadedly engaged nuts, such as thumb nuts 23, for drawing on the bolts B and to clamp the clamp members 2V and I2 together and to the upper part of the f part' of a boat'as maybe desired, as for example,
near-.the aftV ofthe boat, the devices may be detached from the places where they were previously used by loosening and disconnecting the bolts B and then locating the clamp members 2, l2 and I6 at the selected locus, the bolts inserted in place, the clamp members 2 and I2 `as also the clamp member I6 pressed toward the gunwale generally into lateral abutments and then the bolts 5 tightened by screwing down the thumb nuts 23. The device generally will be held firmly in vplace without any idangjerfof the clamp members slaewing or cocking. The i'langes i9 and 2d are so placed and extend along the iiange l5 sufficiently `to give a stable purchase between the clamp meinbers l2 and I8 to prevent any` relative 'ltibiiin'g :or cooking when the bolts are tightened.
While I have herein described and upon the l drawings shown an illustrative embodimentof the invention, it is to be understood that the invention is not limited thereto but comprehends other constructions, arrangement of parts, dertilsfifeatnreseahdthe like; withiit departing iromrthespiritofthe invention. i Y
