Works & Office, 224-230 N. Water St., BAYCITY, MICH MARINE RECORD. [Mar. <9, THE PRYOR PATENT DIPPER TOOTH For Dredges and Steam Excavators. is made entirely of open-hearth steel in two parts, a shank and a removable point. The shank is bolted onto the dipper in the usual way and re- mains stationary, while the removable point is placed over the shank and is bolted thereto. A full set of four points can be changed in from ten to fifteen min- utes, whereas it takes a much longer time to change a full set of the old- style cumbersome iron teeth. These teeth will wear 100 per cent longer than the iron teeth, steel tipped, and will increase capacity of the dredge materially in hard digging.
