OAR-LOCK...
SPECIFICATION forming part of Letters Patent No. 378,722, dated February 28, 1888.
Application filed November 25, 1887. Serial No. 256161.
To aZZ whom it may concern:
Be it known that I, WILLIAM H. RICE, a citizen of the United States, residing at Addi son, in the county of Steuben and State of New York,haveinvented a new and useful Improvement in Oil-PIJOOkS, of which the following is a specification.
My invention relates to improvements in oar-locks; and it has for its objects the provision of a device whereby, by turning opposite edges of the oar-blade up, either a fixed or a feathering oar may be had.
The invention consists in a ring which is pivoted between the arms of the swivel, and is provided with a semicircular slot, the oarshaft disposed within the ring, and collars secured rigidly to the shaft on opposite sides of the ring. One of the said collars is provided with a stop or stud to operate in the slot in the ring and limit the axial motion of the oar by striking against the shoulder at the ends ofv the slot. The stop or stud is so arranged as to be in contact with one of the said shoulders whenever the blade of the oar is vertical. It will be seen that in either of the said positions the oar will rotate in one direction, but will not rotate in both directions. In one case it will turn toward the rower, and in the other case it will turn from him.
In feathering an oar it always turns (at the upper edge) toward the rower, and therefore it is evident that when the oar is arranged so that the stop or stud is in contact with one end of the slot the car will be prevented from turning toward the rower, and will therefore be fixed. YVhen the oar is turned so that the stud or stop is in contact with the other end of the slot, it will be permitted to turn toward the rower, and may therefore be feathered.
The invention is more fully described in connection with the accompanying drawings, wherein- Figure 1 is a perspective View of the oarlock, showing a portion of the gunwale to which it is attached in dotted lines. Fig. 2 is a longitudinal section of the lock. Fig. 3 is a transverse section, line :0 :r, of Fig. 2, with the inner collar removed. Fig. l is a detail view of the inner collar.
Referring by letter to the drawings, A desig- (No model.)
nates the swivel, having the vertical arms or forks B 13, between the upper ends of which is pivoted the ring 0. This ring is provided at the inner edge with a semicircular slot, D,
having shoulders E E at the ends.
F represents the shaft of the oar, which passes through the ring 0, and G H represent collars which are secured to the said shaft respectively on the outer and inner sides of the ring 0. These collars bear against the edges of the ring, and are provided, respectively,with flanges g and h, which pass within the ring, which forms the bearing therefor. These collars are secured rigidly to the oarshaft by the set-screws I I.
K represents a stop or stud on the side of the flange h, which operates in the slot D in the inner edge of the ring.
The operation of the oar in this improved lock will now be evident. The swivel revolves in its socket in the gunwale in the ordinary manner, the ring turns on its pivots, and therefore allows the oar to have a vertical swing, and the oar is further capable of axial rotation in the ring. As before stated, the collars are rigid with the shaft of the oar, and their flanges g and h rotate in the ring. This rotation is only limited by the length of the slot in the ring, and as the slot is, as before mentioned, semicircular, the oar may be rotated through a half-circle. The stud or stop is so arranged (it may be adjusted by turning the collar H on the shaft of the car) that when the blade of the oar is horizontal, as shown at L in Fig. 2, it will be in the center of the slot. If the oar is now turned so as to bring the stud or stop against the shoulder at the end of the slot marked 8 in Fig. 3, (supposing this to be the right-hand oar,) the blade of the oar will be in the vertical position, or perpendicular to the surface of the water. It will now be clearly seen that the oar cannot be turned in the direction indicated by the arrow in Fig. 3, for the reason that the stop or stud strikes against the shoulder and prevents it. The arrow indicates the direction in which the oar must be turned to feather, and therefore if the oar can-- not be turned in this direction the blade thereof must remain perpendicular to the water, and it is in fact a rigid or fixed oar. If, however,
the oar is turned until the stop or stud K bears against the shoulder at the ends of the slot marked 8, its motion in opposition to the di-- rection indicated by the arrow is limited; but it may be turned in the direction indicated by the said arrow, and it can therefore be feathered. Therefore, by simply turning opposite edges of the blade up, the oar may be changed from a fixed to a feathering oar.
I am aware that it is not broadly new to provide oars with locks which will enable the former to be adjusted as either fixed or feathing oars, and I do not claim this.
I am aware that heretofore stationary pins (secured to the oar-lock) have been employed to operate in grooves in the shafts of the cars, whereby the axial rotation of the latter is limited. The oars must, however, in this case be especially prepared for the application of the oar-locks, and, further, the oars are necessarily weakened by the grooves formed therein.
There is no preparation of the oar necessary to apply my oar-lock.
My oar-lock will suit any oar whose shaft will pass-through the collars, even should the said shaft be much too small for the opening in thecollars, for in the latter case the setscrcws will engage the shaftand bind it rigidly in position.
Various other devices have, I am aware, been employed to allow the shaft of the oar limited axial rotation, in the majority of which a special preparation of the oar is necessary prior to applying the look.
It was my object to provide a lock which could be used with any car without preparation, and I have attained this object in the device which has been herein described.
Having thus described my invention, I claim 1. In an oar-lock, the combination of the pivoted ring 0, having a slot, D, in its inner edge, the car passing through the ring, the outer collar, G, embracing and secured to the oar and bearing against the outer side of the ring 0, and the inner collar, H, secured rigidly to the oar and bearing against the inner side of the ring, and having the stop or stud K to operate in the slotD and limit the axial rotation of the oar, substantially as and for the purpose specified.
2. In an oar-lock, the combination, with the oar, of the swivel A, the ring 0, pivoted be tween the arms thereof and having the semicircular slot D in its inner edge, the outer collar,G, embracing the oar and having the flange gfitting in the ring, the inner collar, H, embracing the oar and having the flange h fitting in the ring and provided with a stop or stud, K, to operate in the slot D, and the set-screws I I in the collars to secure them rigidly to the car, substantially as and for the purpose specified.
In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two witnesses.
WILLIAM H. RICE.
