TRANSOM LIFTER.

N0. 246,639. Patented Sept.. 6,1881.

M D WW v 6 HENRY E. RUSSELL, JR, F NEIV BRITAIN, CONNECTICUT, ASSIGNOR TO THE RUSSELL & ERWIN MANUFACTURING COMPANY, OF SAME PLACE.

TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 246,639, dated September 6, 1881.

Application filed July 21, 1881.

To all whom it may concern:

Be it known that I, HENRY E. RUssELL, Jr., of New Britain, in the county of Hartford and State of Connecticut, have invented cerrain new and useful Improvements in Transom-Lifters, of which the following is a specification.

My invention relates to transom-lifters in which the rod is jointed and provided with a roller at the joint; and the objects of my improvements are to keep the rod from bending and to make it work smooth and easy, with a rolling movement over the casing. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a side elevation, andFig. 2 a front elevation. The device is therein represented as applied to a transom which is hinged at the bottom, butit is applicableto transoms hinged at the top or middle.

A designates a bracket or arm, designed to be secured to the transom, and to which arm the upper member, B, of the lifting-rod is pivoted.

C designates a socket, through which the lower member, D, of the lifting-rod passes, and in which it is fastened in any desired position by means of the set-screw a or other suitable fastener; andEa guidefor governingthe lower member, D, of the lifting-rod. The upper and lower members of the lifting-rod are pivoted together at their meeting ends, as shown. Transom-lifters consisting of the parts thus far specifically described are old and hereby 5 disclaimed. Upon the lower end of the upper member, B, I place a forked roller-frame, 1), within which is the roller 0, and upon the up per end of the lower member, D, there is a (No model.)

forked frame, (I, while the axle-pin, upon which I the roller is mounted, passes through the meeting ends of the frames b d, and forms the joint which connects the upper and lower members of the lifting-rod. The roller should be of such size that its periphery will bear against the casing when the lower member of the lifting- 5 rod is supported by the guide E and socket C, and said member is substantially parallel to thefaceofthecasing,asshowninFig.1. When the transom is opened the upper member of thelifting-rod swings outward, as indicated by broken lines in Fig. 1, and has a tendency to spring the upper end of the lower member inward toward the casing, so that when not supported by the roller 0 the rod bends inward and causes the parts to bind and not work 5 smoothly; but when the joint is supported by the roller 0 said roller travels up and down the casing, keeps the lower member of the rod parallel to said casing, and causes the parts to work smooth and easy.

I claim as my invention 1. In a transom-lifter, the combination of the upper and lower members of the jointed rod and the supporting-roller at thejoint thereof, substantially as described, and for the purpose specified.

2. In a transom-lifter, the combination of the upper and lower members of the liftingrod, the forked frames 1) d, and the roller 0, connected together by an axle-pin common to both frames and the roller, substantially as described, and for the purpose specified.
