CHARLES M. BURGESS, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE RUSSELL & ERWIN MANUFACTURING COMPANY, OF SAME PLACE.
TRANSOM-LIFTER.
SPECIFICATION forming part of Letters Patent No. 512,275, dated January 9, 1894.
Application filed August 23, 1393- Serial No. 483,375- (No model.)
To all whom it may concern.-
Be it known that 1, CHARLES M. BURGESS, a citizen of the United States, residingat New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Transom- Lifters, of which the following is a specification.
My invention relates to improvements in transom lifters, and the objects of my improvements are simplicity and economy in construction and convenience and efficiency in operation.
In the accompanying drawings; Figure 1 is a front elevation of my transom lifter, together with a portion of the transom and casing. Fig. 2 is a side elevation of the same. Fig.3 is a detached view of the fastening device. Fig. 4 is a section of the same on the line as 00 of Fig. 3, together with the lifting rod; and Fig. 5 is asection thereof on the line y y of Fig. 3, the central parts being shown in elevation. Figs. 3, 4 and 5 are on an enlarged scale.
A designates the transom and B the casing by its side. The transom bracket 6 is connected by means of the link 7 with the transom rod C, the crank arm of said link being received in the eye 8. This eye is formed by a multiple coil in the transom rod, whereby the ends projecting above and below said eye are spread apart laterally, and when supported in the bracket eyes 9, with the crank arm of the link in the eye 8, said rod will be held without any liability of its turning over and working out of place.
The fastening device for holding the rod in different positions consists of a case or frame D and a spiral spring 10 with its ends turned outwardly to form the handles 11. The case D is formed with a vertical opening through which the lifting rod C extends, and openings on its front through which the handles or arms 11 extend as shown. The spring is wound of a size which will firmly embrace the rod and adhere thereto by friction, excepting when the arms or handles 11 are compressed to unwind the coils of the spring and open it. The parts are arrangedin the position shown and in this position the friction of the spring upon the rod is sufficient to firmly lock the rod in place against being moved either up or down. By pressing the arms orhandles 11 toward each other, the coils of the spring are unwound sufficiently to permit the rod to slide freely up or down therethrough for operating the transom.
By my improvements, I form an efficient and operative lifting rod and'the eye for the link in one piece of wire, whereby an efficient rod is formed at a small cost. The holding or fastening device is also of a very simple and inexpensive construction, is very easily and conveniently operated and efficiently locks the rod in place.
While I prefer and undoubtedly will employ both of these improvements in a single transom lifter, it is evident that either one of them could be used in a transom without the employment of the other, the holding device operating the same on transom rods in general that it does upon the particular rod herein shown.
I claim as my invention-- l. The herein described transom lifter having the eye 80f the rod C formed in multiple coils and the link connected therewith by its crank arm extending through said eye, substantially as described and for the purpose specified.
2. The fastening device for a transom lifter, consisting of the spiral spring having projecting handles or arms, and a suitable case for confining said spring and arms with the rod extending through the coils thereof, substantially as described and for the purpose specifled.
CHARLES M. BURGESS.
