2nd patent number appearing on CRAFTSMAN ROBO-GRIP(R) self-adjusting pliers. "Self-adjusting utility pliers are disclosed in pending U.S. patent application Ser. No. 654,405 filed Sept. 26, 1984, now U.S. Pat. No. 4,651,598; issued Mar. 24, 1987. The tool therein disclosed is intended for the same use and purpose as the aforedescribed prior art pliers but has the clear advantage of single-handed adjustment. Further, the pliers are adapted to slideably close upon a work piece in response to manual closing action on the handles, and, in response to contact with the work piece, automatically lock against further sliding action and shift from the sliding to a pivoting mode whereby continued exertion of manual force on the handles causes increased gripping action on the work piece."

Abstract: My improved scythe resembles in general appearance a common scythe with the web thickened or stiffened back of the cutting part of the improved scythe behind the edge, the blade increases gradually in thickness to the back part of the web, and gradually diminishes again in thickness outward to the back edge. The greatest thickness is along the web through its whole length. The thickness must be sufficient to give the proper degree of stiffness, and strength although it may be varied to suit the purposes to which the instrument is to be applied, some uses requiring greater firmness of structure than others. From the thickest part of the web, the back part of the scythe blade is curved upward or downward one side of the web, when the scythe lays horizontally, presents a surface rounded outward, the other a surface rounded inward, either may be turned downward next to the earth in cutting as convenience may require. Instead of the heavy and solid back of the common scythe, the back of the improved scythe is thin, the weight of the instrument is thereby diminished and the ease with which it operates in mowing much increased. The scythe may be made of any suitable length or width according to the kind of mowing for which it is intended. Claim: Thickening and strengthening the web of the common scythe.

Abstract: I have invented a new and useful improvement in modes of fastening shutters for windows in stores and other buildings where security is required. Claim: The mode of fastening window shutters by means of a fiat spring fastened on the inside of the window frame with a shoulder, or bent at right angles at its loose end upon which rests a sliding key held in a vertical position by staples, and which when the bolt from the outside is passed through the bar, and frame comes in contact with the spring causing it to yield inwvard and pass from under the key, said key from its gravity drops into the eye of the bolt the shoulder on the key retaining it in a proper position, by which means the shutter is secured from the outside of the building, without the inconvenience of passing to the inside to insert the key, as in the usual mode.
