2. Claims.

My invention relates to a combined oar lock and car and whileobviously adaptable for'use in rowing, relates-more particularly to a combination for use in sculling. An object ofmy-invention istoprovide a novel combined oar and car lock.

A further object is toprovide an improved and novel oar.

A further object is to-provideaanimproved and novel oar look.

A further object is to provide anoar'lock embodying novel means foradjusting the length will be readily apparent tothose skilledin the art upon reference, tothe drawings inconnection 25 with the following detailed description.

In the drawings wherein like reference characters refer to like parts throughout:

Figure 1 is a perspective view of my improved car and oar lock;

30 Figure 2 is a longitudinal vertical; section through the locktaken on a plane corresponding substantially to that indicatedby the line 2--2 of Figure 3;

Figure 3 is a transverse verticalsection through 36 the lock takenona plane corresponding substantially to that indicated by the line- 3-3 of Figure 3;

Figure 4 is an elevation of the blade of the oar;

40 Figure 5 is a longitudinal horizontal section through the car blade taken substantially on the line 5-5 of Figure 4;

Figure 6 is a transverse vertical section taken on the line 6-6 of Figure 4; and

45 Figure 7 is an enlarged detail of a portion of Fig. 5.

Referring more particularly to the drawings, l0 indicates generally an oar and M an oar lock therefor. The car In comprises a central body 50 portion l2 having one end adapted to be removably seated in a socket l3 formed on an ear I4. The ear I4 is apertured to receive a bolt l5 which connects said ear to a pair of similar ears l6 having a socket member formed thereon. One

55 end of a handle portion I8 is adapted to be seated in said socket By-l'oosening the'nut |9of the bolt IS the handle 8 can be swung through a vertical arc to anydesired vertical angle with respect to the body portion |'2-of the oar; Tighteningot the nut i9 secures the handle l8 in any 5' selected position or vertical angle with respect to the body |2 ofthe oar.

The other endof the body; |2'* is suitably secured-to the blade 9 by being secured in anysuitable manner in a socket The socket 2|] has 1t! a base flange 2| suitably apertured to receive rivets or bolts 22, 23: The rivets 0r bolts 23 attach thesocket 20 to a strip 24 having end portions 25thereofturned at right angles theretoin parallel relationship; The end portions 25 II are formed to provide aligned apertures therein which receive a bolt orrivet 26 upon which the blade 9' is swingably mounted. The bolts or rivets- 22-01? the flange 2| areattached to a strip 28 which crosses the strip 24 at right angles g thereto. End portions-29 of the strip 28* are bent at' right angles thereto in substantially parallel relationship to each other: As indicated by the dotted-lines 21; Fig: 5; the: end portions 29 serve as stops to limit the, swinging" movement of the The' blade 9 comprises a substantially fishtailshaped member: Theblade 9- may be formed of a single sheet" of suitable material which is folded upon itself to form a pair of abutting plates 30 and 3| The'foldededges'of said plates 30' and 3| may be enlarged and swaged to provide abearing 32' to receive the bolt or rivet 26. A reinforcement 8.maybe'appliedto*the blade 9, if desired; and may comprise a strip having its end portions 33; 34 folded" around the" bearing 32. Rivets or bolts 35 secure the portions 3|, 32 of the blade together and may also secure the ends 33, 34 of the strip 8 together.

From the foregoing, it is apparent that as the oar Ill is swung back and forth, the blade 9 will be swung to and fro by the resistance of the water. The swinging motion of the blade will, as aforesaid, be limited by the stops 29. This particular motion is in the nature of that exerted by the tail of a fish and serves to propel the boat when a single car is used over the stern to scull the same.

In sculling, I have found that the maximum efficiency is attained when the blade enters the water at a certain angle which angle must be maintained to maintain the efiiciency. That is, the oar should be swung back and forth in the same inclined plane constantly as variations in the angle of the plane detract from the efiiciency of the operation. To this end, I have provided means included in the oar look I I whereby the car may be maintained at any desired angle with respect to the water throughout the sculling operation.

The oar lock H comprises at least one base 40 having depending legs 4| which are adapted to fit over the stern or gunwale of a boat. Suitable means such as the thumb screws 42 may be used to secure the lock to the boat. A member 43 is mounted on the base 40 for turning movement through a vertical arc. The ends of the member 43 are reduced as at 49 and are received in bearings 48 formed in the ends of the base 45. The extremities of the reduced ends 59 are threaded to receive bearing nuts 50. By loosening the nuts 50 the member 43 may be turned to any desired position and secured in such position by tightening the nuts. A recess 44 is formed on the member 43 and receives one plate 45 of a hinge member 46. Th recess 44 may be eliminated where a square or angular member 43 is utilized. The other plate 41 of the hinge 46 is suitably attached to a base flange 5! which has an upright socket member 52 formed thereon. A

bushing 53 is formed in the socket 52 to provide a bearing for a pin 56 which is pivotally mounted therein. The lower end of the pin 56 is tapped to receive a bolt 55 which carries a washer 54 seated in a suitable recess in the bottom of the flange 5!.

The upper end of the pin 56 has an oar receiving clamping member 58 formed thereon and which is flanged as at 59. The other clamping member 62 is of generally similar shape and has flanges 6! formed thereon. The members 58 and 62 are adjustably connected together by suitable bolts 50 which pass through suitable apertures in the flanges 59 and 6! thereof. It will be noted that the clamp for the oar resembles an automobile connecting rod bearing time if it is desired to use the oar and look upon and it may be said that I have found that such a bearing makes an ideal clamp, it being only necessary to saw off the connecting rod and turn it down to form the pin 56.

From the foregoing, it is obvious that by turning the member 43 to a suitable position and there securing it, the angle of the oar Ii) may be adjusted to the maximum efiiciency and thereby maintained for an indefinite period. At the same another boat having higher sides or stern, it will be necessary to determine a different angle. Hence, the adjustability of the member 43 is of importance. The clamping members 58 and 62 provide means for varying the working length or leverage of the oar to suit the particular boat.

It will be noted also that the hinge 46 permits the oars to be raised clear of the water and swung into the boat without disturbing the angle of the member 43. Thus, the particular oar lock is not limited for use alone with a single sculling oar, but two or more may be provided to opposite gunwales of a boat for use with the usual oars in ordinary rowing.

While I have shown and described What is thought now to be the preferred form of oar angle adjustment, oar lock, oar and combination .thereof, yet it is apparent that the same are susceptible of other embodiments and combinations. Therefore, it is to be understood that the foregoing disclosure is to be regarded as illustrative only and that it is not my intention to limit myself to the particular embodiments and combination shown except as hereinafter claimed.

I claim:

1. An car look for boats, comprising a pair of spaced base members, said members including means for detachably connecting said base members to the gunwale of a boat, aligned bearings in said members, a shaft mounted for rotation in said bearings, the ends of said shaft being threaded and extending beyond said members, lock nuts on said ends of said shaft and bearing against said members to lock said shaft against rotation, an oar-engaging member pivotally mounted on said shaft intermediate said members, to permit the working movement of an oar, and said lock nuts and shaft comprising means for positioning and maintaining said oar engaging member at any selected vertical angle with respect to said base.

2. An oar lock for boats, comprising a pair of spaced base members, said members including means for detachably connecting said base members to the gunwale of a boat, aligned bearings in said members, an intermediate member mounted between said members, end portions of said intermediate member being reduced to fit in said bearings to permit rotation of said intermediate member, the ends of said reduced portions being threaded and extended outwardly of said members, lock nuts on said threaded portions and bearing against said members to lock said intermediate member against rotation, an oar-engaging member pivotally mounted on said intermediate member to permit the working movements of an oar, and said lock nuts and intermediate member comprising means for maintaining said oar-engaging member at any selected vertical angle with respect to said base.
