An improved firearm having a low creep, safety trigger. The firearm includes a frame, a barrel attached to the frame, a firing mechanism, a step having an adjustable step height, an over travel stop, and a sear and step trigger assembly with a secondary sear block. The secondary sear block is selectively movable between a first blocking position and a second non-blocking position.

A mud guard adapted for releasable attachment to the saddle of a bicycle comprises a sheet of a semi-rigid body adapted to be folded so as to define a long projecting open ended nose or snout sleevable over the forward end of a bicycle saddle so that the tail of the so-folded sheet may be extended rearwardly of the saddle and outwardly thereof in a cantilevered manner over and in spaced relationship to the rear wheel of the bicycle.

An assembly for testing the inner diameter of a rifled barrel of a firearm and a method of manufacturing the same. The assembly has a frame with side air discharge apertures and is intended to be connected to an air gauge. The assembly has a timing sleeve that is removably mounted to the frame such that the sleeve can be replaced when it becomes worn or when the assembly is intended to be used with a barrel having a different type of rifling. The assembly also comprises a wear ring such that the wear ring and timing sleeve absorb abrasive contact in the barrel to reduce abrasive contact by the barrel on the frame.

Apparatus for retrieving objects from the ground has a ground-engageable drum rotatably mounted on an axle extending between opposite side plates, the drum having a plurality of drum fingers extending radially outwardly from the drum for piercing the objects as the drum is pushed over the ground, and a slotted comb oriented for the in seriatim passage of the drum fingers through respective slots of the comb as the drum is rotated for dislodging the objects as the drum fingers are pulled away therefrom.

Leaf gatherer and disposal apparatus

A method of recovering tin from tin dross consisting of positioning a barrel having an apertured bottom and charged with a supply of the tin dross upon a partitioned collecting tin mold, with the components thus arranged being placed into a furnace for subjecting the components and tin dross charge to a temperature approximating 700.degree. F. for a time duration approximating 5-6 hours and allowing the developed molten free tin to flow downwardly of the barrel and through the apertures thereof and into and between the partitions of the collecting tin mold, and withdrawing the collecting tin mold for cooling before removing the cast tin bars therefrom. The apparatus aspect relates to the design of the barrel and collecting tin mold.
