"What we claim as our invention, and desire to secure by letters patent, is not the employment of metallic packing in a stuffing box generally, but the employment of metallic packing, arranged, shaped, and combined in a peculiar way, viz: in a metallic matrix or cup, shaped and arranged so as to allow the piston rod or shaft, passing through the stuffing box, liberty to vibrate laterally to a sufficient extent to meet the unavoidable irregularities of the engine to which it may be applied, and at the same time support within it, conical shaped metallic rings, moving against and along the piston rod or shaft, as well as against and along its (the cups) oblique surface, so that, as the inner surface of the packing rings wear away, the rings may, by the proper application of springs or screws, pressing them in the direction of the axis of the piston rod or shaft, be advanced along the conical surface of the matrix, so as to maintain a perfect contact of surface, both with the piston rod or shaft, and with the matrix. We also claim the use of the said vibrating cup, without the metallic packing, in which case we use hempen or other packing in connexion with it."

7. For an Improvement in Machinery for Drilling Rock; P. T. Wightman and H. Vaughan, Greenwich, Kent county, Rhode Island, November 6. Claim.

without it is set to the proper numbers on the index to which the ward will correspond; the whole being constructed as set forth.

"Secondly, I claim the method of fastening up the key-hole, by means of a movable escutcheon and catch bolt, as set forth, in combination with the apparatus for forcing the tumblers, for farther change of position, in drawing the bolt.

"Thirdly, I claim throwing the projection on the bolt into the centre of the tumblers, as described, so that the wards can be disarranged when the door is unlocked, to prevent an impression being taken from them.

The patentee says, "I form in the rear of the cutting edges of each chisel, a supplementary chisel, by grooving out the side of the chisel plate, and making of said groove a vent for said supplementary chisel, which shall increase in width as it retreats and opens into the discharging vent of the next main chisel."

Claim."What I claim as my invention, and desire to secure by letters patent, is the supplementary chisel, and its discharging vent, as combined with, or applied to, each of the main chisels, and the discharging vent of the chisel in rear of it, the whole being substantially as specified. I am

aware that ice cutters have been made with guides, hinged or so connected with them, as to be caused to rest and move in a parallel groove to that which is to be cut; and therefore I do not claim a guide so combined with, or arranged upon, the ice cutter; but that which I do claim, is the rudder or guide, as applied in the rear of the ice cutter, and combined with it in manner as described, and for the purpose of causing the ice cutter, by the aid of the groove it is cutting, to cut in a straight direction."
