Description
UNITED STATES PATENT OFFICE.
JOHN D. MARSHBANK, OF LANCASTER, PENNSYLVANlA, ASSIGNOR TO IIIMSELF AND WILLIAM MCCONKY.
IMPROVEMENT IN CANAL-WICKETS.
Specification forming part of Letters Patent No. 4l,463, dated February 2, 1864; antedated December 21, 1863.
To @ZZ whom t may concern,.-
Be it known that I, JouN D. MAESHBANK, ofthe city of Lancaster, county of Lancaster, and State of Pennsylvania, have invented new and useful Improvements in Canal-fickets; and I do hereby declare that the follow' ing is a full and exact description thereof, ret'- erence being had to the accompanying drawings, and to the letters of reference marked thereon, making a part ot' this specitication.
The nature of my invention consists in the shape and construction ot' the movable journals, cast separately, to be attached to a castiron wicket for canal-locks, but titted and keyed on securely to each end of the wicket i1 sockets with side ledges, so as to be easily removed and replaced by new ones when worn, which saves the expense ot' a new wicket. As now the case,` th e wicket has to be cast to gether solid with the journals, and thus to be replaced 5 but by these movable journals the same wicket can be used for many years.
The object and advantage of my invention are to easily remove the worn-out journals and replace them by new ones, while the wicket can be used for many years, and always retained and kept at a smaller expense in better working order than when the journals and wicket are cast solid, and the whole wicket become useless.
Figure l represents a perspective view ofthe wicket with its movable journals. Fig. 2 exhibits the journal-socket and ledges. Fig. 3 represents an end View ot' the wicket.
A represents a cast-iron plate or wicket, of the usual size employed in canal-locks. At the upper and lower parts of this wicket there are raised ledges B ou each side of the plate A that form recesses or sockets G to receive the lips of the journal D. rIhe journals D D are cast separately, round at top, with round shoulders E E, tapering oft' to the bottom. Each journal is cast with two lips, G G, (having two square sides,) which tit closely over the sides of the plate within the ledges B B, completely preventing any lateral movement A wedgeshaped key, H, is inserted in the apertures J J, and passes through the lips G and through the center of the socket C to prevent the journals D from moving out of their place, and the journals are secured and held firmly to the platev by the ledges B and key H. The wicket is fitted into the canal-gate in the usual manner.
What I claim as my invention, and desire to vsecure by Letters Patent, is-
