Patent Canal Boat Spring. --- We were yesterday invited, by Mr. Edward Townsend of this place, to witness the utility of a Spring which this gentleman has recently invented, to be used on Canal boats. The invention, we think promises great and lasting advantages to the public, especially to proprietors of these boats. Its construction is simple, and such as to render it nearly as easy for the horse attached to the boat, to start it, as to propel it after it is under way, as it effectually relieves him from the dead pull, in starting, and from the frequent wrenches, which, without it, must necessarily attend Canal Boat Navigation. We are confident that every boat on the canal will be furnished with one of these springs, when their utility is generally know. The expense for one will be trifling in comparison to the benefits resulting from its use.
Mr. Townsend, we learn, has made application for a patent for the invention. -- Palmyra Herald.
