    Abstract: This specification discloses a fire door lock set incorporating a latch bolt having a latch bolt stop lever which is normally maintained in an ineffective position by a fusible pin, but which drops into a position holding the head of the latch bolt in door closing position when the pin melts at a predetermined temperature caused by a fire condition. The present invention relates to the lock set incorporating a latch bolt and associated mechanism in a fire door and is concerned primarily with a latch bolt stop lever which is under the control of a fusible pin.

    Abstract: This specification discloses a compound action tool of the type commonly employed for crimping purposes with a wire stripper and bolt cutter being incorporated in the tool. The tool comprises a pair of handles having laterally extending ears in overlapping relation and pivotally connected. An arm is pivoted to the end of each handle and terminates in a jaw. Each arm has a lobe extending laterally towards the other arm. Each arm is formed with an arcuate slot in the region of the lobe with each slot receiving a pin on the lobe of the other arm. The end edge of each lobe is formed as a curved cam surface which is engaged by a portion of the jaw on the other arm which projects therefrom and overhangs the cam surface. A pair of plates having end portions formed as wire stripping jaws are pivotally mounted on the pivot which connects the handles. One of these plates is fixed to one handle and the other is adjustable on the other handle. An adjusting disc is pivoted on the latter handle and is connected to the adjustable plate by a pin and slot connection. A spring ratchet cooperates with the disc to secure an adjusted position of the stripping jaw controlled thereby. The arms are deformed in the regions of the lobes to provide a sliding face to face engagement of the latter. Each arm and the lobe thereon is formed with a series of openings for bolt cutting purposes.

    Abstract: This specification discloses several implements that are intended for use on the mouth of a fish for hook retrieving purposes. They are all characterized as being of the pliers type with each implement comprising two pivotally connected lever members. These lever members are of a steel rod having appreciable properties of elasticity and resiliency. One end of each rod is folded back upon itself to provide a handle skeleton of double thickness with the free ends of the rods bent into confronting end portions which cooperate as abutments for limiting the extent to which the handles may be compressed. Each handle skeleton is covered by a hand grip of plastic and each end portion is capped by a cup shaped member of plastic. The present invention relates to implements that are intended for use with the mouth of a fish for the broad purpose of retrieving a hook therefrom or kindred purposes. The implements are all of the pliers type and the invention is concerned primarily with the construction of the lever elements which are pivotally connected and which provide handles on one side of the pivot.
