Improvements in Oar Locks.
I, WILLIAM FRANKLIN SPENCE of Pass Christian, County of Harrison, State of
Mississippi, United States of America, Physician, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention relates to an improvement in oar locks, and its novelty will be fully
understood from the following description. The objects of my invention are to
provide a safe oar lock for life boats, yawls, or other boats that will prevent the
loss of oars when boat is capsized or in a heavy sea.
I attain these objects by the mechanism illustrated in the accompanying drawings
in which :-
Figure 1 is a side view of oar lock.
Figure 2 is an end view of oar lock.
Figure 3 is a view of small end of clamp.
Figure 4 is a side view of clamp.
Figure 5 is a view of large end of clamp.
Figure 6 is a top view of half of clamp, showing interior of same.
Figure 7 is a side view of oar.
Figure 8 is a side view of large key.
Figure 9 is a side view of small key.
Similar letters refer to similar parts throughout the several views.
In the drawings:
A refers to a lock for oar; said lock being provided with a cover or fastening, as
shown by B, which is held in position by means of a hinge C, and key D. The
lock A, is held securely by means of a pivot E, attached to bearing F, said
bearing being held in position by a key H, passing through upright G₁ of
casting G and the latter are held securely in position to boat by means of a
clamp K.
Resting within lock and between two clamps or sectional sleeves M provided with
flanges is oar L; said clamps being provided on their inner face with bits N, which
penetrate the oars, when within clamps M, and prevent sliding of oars while the
flanges upon the clamps, as shown in Figure 2 jam against the sides of lock A, and
cover B and enable the oars to be held securely in position.
O is a slot in lock A. and in which head of key rests.
The
In practice the parts G are attached to boat by means of clamps K; the
bearing F to which lock A is attached by means of pivot E is placed in position
and the key H inserted through parts & as shown. The clamps M are placed on
oars, and covers B are raised and the oars are placed within the lock A.
covers B are then lowered and fastened by means of keys D, and the oars are ready
for use.
The locks A can be swung in any direction by means of pivot E, and the
oars when not in use can rest on or outside of boat. The oars when in use never
chafe or wear in the lock, are always adjusted to boat, and by use of same an even
motion is given.
The lock has no lost motion either in pulling or backing, and by the use of same
a lock for sculling and steering is provided which, to a great extent, obviates the
necessity of rudder. Should there be a break, the uprights G¹ to which bearing F
is attached, will supply a temporary oar lock until lock A can be replaced.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The combination with an oar of a sectional sleeve having the flanges on its outer

a pintle a cover or cap hinged to the lower section and adapted to embrace the
sectional sleeve on the oar, the casting G having the uprights G¹ provided with
journalled apertures H bearing F in which the lock is pivotted arranged between
said uprights the pin passing through the uprights and also through said bearing
so as to pivotally connect the same, and the angular clamps K for securing the
casting to a bolt the lock being also provided with a securing key on the hinged
section all adapted to operate substantially as specified.
