JOSEPH YV. NORCROSS, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO W. YV. VILCOX AND JOSEPH HALL, JR., OF MIDDLETOWN, CONNECTICUT.
IMPROVED ROW OR SCULL LOCK.
Specification forming part of Letters Patent No. 44,373, dated September 20, 1864.
T0 all whom it may concern:
Be it known that I, JOSEPH W. N oRcRoss, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Row and Scull Lock; I and do hereby declare that the following is a full, tlcar, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciticatiomin which- Figure l represents a longitudinal vertical section of my invention, taken in the plane indicated by the line x w, Fig. 2. Fig. 2 is a plan or top view ofthe same.
Similar letters of reference indicate like parts.
lt consists, further, in the application of one or two lnovable or yielding jaws,in combination with the movable joint and oar, in such a manner that the oar can be instantly shipped or unshipped, as circumstances may dictate.
A represents a rowlock, composed of a ball and-socket, or other universal joint, and made. of wood or any other suitable material. The handle B of the oar is connected to the universal joint, either permanently or so that it can be detached therefrom, and thc universal joint may either be permanently tixcd to the gunwale of a boat, or within the ordinary rowloek, or it may b e mede in such a manner that it can be shipped or unshipped.
The most convenient form of making the universal joint, suitable for lny rowlock, is that of an ordinary ball-and-socket joint, and the `nall may be cast ot' iron, or made of any other suitable material, and provided with two arms extending in opposite directions, so that the handle of the oar may be secured to them or the handle may be passed through the ball, or connected to it in any other suitable mannein The socket may be formed either of two jaws, which inclose the lball completely after the same has been introduced and do not allow of its being unshipped except it' one of the jaws is removed, or said socket may be made of one stationary jaw, a, and
one yielding jaw, b, formed as shown in the drawings. Thesejaws are so formed that the pressure of the ball in rowing presses the same down, and, moreover, the yielding jaw is situated behind the ball, so that inrowing the stationaryjaw sustains the principal pressure.
Thejaw b is made yielding, so that the oar can be instantly shipped or unshipped. A spring, C, may be applied behind said yieldingjaw to keep the same close up to the surface of the ball.
This improved rowlock allows of lerforming all the motions which can be performed with an ordinary oar. The blade of the oar can be turned so as to meet the wind edgewise, or, as it is commonly termed,to bring the blade to a feather-edge. Unlike all the rowlocks, it makes no noise in the operation of rowing, and for steering purposes or for sculling it has many apparent advantages. It can be used as a sweep 011 all kinds of floats or boats. The rowlock can be fastened to the boats or floats with screws, rivets, bolts, or nails, or by any other ordinary method of fastening rowlocks. It can be used with or without springs, and thel ballcan be made solid or hollow; In the movable rowlock is a pin-hole to fasten the ball ett'ectually, should it be desirable. The socket can loe connected either to the boat orto the oar. The oar, when used as an elastic oar, has strong springs in front ot' the rowlock, and in that case the rowlock is made to workin a slide. v
The principal advantages of nty rowlock are as follows: First, it works without noise; second, it is durable; third, it is perfectly reliable, and cannot be unshipped with the motion ofthe sea; fourth, it is worked and used with much more ease than any other rowlock; fifth, it enables a common oar to bc used in place of the rudder; sixth. it allows ot' having the oar remain connected with the boat or unshipped at pleasure.
I claim as new and desire to secure by Letters Patent- The movable or yieldingjaw b, with theretaining-spring C, applied in combination with the universal joint and with the oar, in the manner and for the purpose substantially as herein shown and described.
JOSEPH W. NORCROSS.
