It results from this arrangement that blows upon the bit C, in dressing a stone, more firmly clamp and hold the parts together, while to loosen them, all that is necessary is to tap the plate B on the end opposite the cutting point or edge, which unwedges the two plates and releases the bit. Two recesses are provided in the plate B, so that when the bit is worn down it can be set further out from between the plates A and B. When one end of the bit becomes so worn as to be no longer available, the bit is reversed, and the other end applied to dressing the stone. Thus the bit may be used until it is almost entirely worn away. It is retained firmly, and yet is instantly detached for sharpening or for adjustment. The head is made of Malleable Iron, and the blades of the _very best quality hammered cast steel_, tempered the whole length, and do not require blacksmithing, but only to be ground when dull. The price places these Picks within the reach of every miller. Twelve 6 inch double blades sent with each head. Hoisting Screw, Wrench, Bails and Pins. [Illustration] We are well prepared for making the above articles and have all ordinary sizes on hands ready for use. The outfit is of the very best material; the wrench, screw, &c., is of wrought iron, and together with all the parts is in fine proportion and of great strength. Damsels. These we generally make to order, but we keep at all times a few of such as are mostly called for. Those with from three to five beaters, with staff, and all wrought iron, are mostly ordered for merchant and sometimes custom mills. We have a variety of patterns for cast iron damsels with oval beating part. We turn and polish both kinds so as to make a neat and useful article. In ordering these some needed dimensions are necessary to enable us to meet expectations. [Illustration] ELEVATORS. [Illustration: Fig. 1.] This engraving represents the head and part of the trunk of an Elevator, or what is termed an elevator head; Fig. 2 (on next page) represents the elevator foot. An elevator head and foot as furnished by us includes Fig. 1 and Fig. 2 with turned iron pulleys in them, the necessary shafting, and an outside bevel or spur gear wheel or turned pulley to receive power for driving the Elevator. NOTE.--The iron spider as represented leaning against the Elevator head (Fig. 1) has no connection with any part of it except to show the shape of our patterns in that line.
