IMPROVED OAR LOCH. ed with lightness and there is perfect freedom in the handling of the oar which will not unship in the roughest weather. Clamped around the oar is a hinged ring the edges of which have outwardly projecting flanges. This ring is fitted to turn within another hinged ring having trunnions by which it is mounted in the frame in the boat bracket. These two rings con stitute a fixture upon the oar and are made as light as possible consistent with the wear and strain brought TOMPKINS' IMPROVED OAR LOCK. to bear upon them in rowing. The boat bracket is se cured to the gunwale and has a downwardly project ing tubular arm in which the shank of a U-frame is held by a spring pin at its lower end. The bracket is not necessarily a portion of the oar lock as the shank of the frame can be attached to various styles of boats in a multiplicity of ways. In the upper extremities of the frame are journals to receive the trunnions of the outer ring one journal being positively inclosed at the top and provided with an inner vertical recess to facili tate the insertion of the trunnion and the other being open and provided with a hinge cap as shown in the =GORDEN'S IMPROVED PRINTER'S CHASE. small view. A properly arranged spring holds the cap in its closed horizontal position. When it is desirable to re ceive the oar the cap is thrown back agojust the pres sure of the spring or the spring is boot koward to re lease the cap. The oar can be readily and safely ad justed in the frame or removed therefrom. This oar lock relieves the strain of the oar upon the hand at the entrance of the oar and to a great extent upon the stroke. It prevents the oar from slipping inboard and outboard and permits the ready and very easy accom plishment of the movement necessary for feathering. This invention has been patented by Mr. Alfred H. Tompkins of 70 Hancock Street Brooklyn N. Y. IMPROVED PRINTER'S CHASE. The top and bottom pieces of the chase for attach ment to a job press as usual are p
