Title: Improvements in traps for mice, rats, or other vermin
IPC: A01M23/30
Filed: 1920-08-19
Abstract: 171,493. Mark, W., and Parker, F. J. Aug. 19, 1920. Animal traps. - A trap of the type having a cranked striker frame c is set automatically when the striker frame c is turned through about 90‹, and the crank e passes a dead-centre; the spring d that operate the striker frame when released also retains it in the set position. In setting the trap, the crank e depresses the rear end of the tread-plate f, causing it to rock on projections h and to take up the raised position. The sensitiveness of the trap is varied by causing the end n of the spring d to engage any one of the notches m on the bait-holder l, or the holder may be adjusted by the engagement of the notches with a hole in the base a. The edge g<1> of the upturned end of the plate f is serrated to deter the animal from approaching the trap from the rear.

The mould is immediately capped, after pouring, e.g. by insertion of a plug or by a water spray, and tilted to lie in a horizontal position. In Fig. 1, the mould 14 is lowered on a platform 19 during pouring to maintain a constant distance between the molten metal surface in the mould and the spatter head 13. After capping and pouring, the spout 12 is removed and the mould 14 raised between roller guides 21, 22 until its bottom lies adjacent a horizontal roller bed 36. The roller guide part 21 is pivoted at 23 to lower the mould 14 on to the roller bed 36 where it is slowly rotated. A plunger ejector 40 removes the solidified ingot 43 from the mould whilst still hot. Hollow ingots can be made by partially filling the mould and rotating the mould in its horizontal position and/or pouring position at high speed to subject the ingot to centrifugal force. In an alternative embodiment (Fig. 5) four moulds are carried on a turntable 51. A hoist 24, 54-56, lifts a mould 14 to a pouring spout 12 at a casting station and lowers the mould during teeming on to the turntable 51. After 90 degrees rotation of the turntable 51 the mould 14 is lifted to an extraction and rotation station in a carriage 63. At a station directly opposed to the extraction and rotation station a fresh mould (not shown) is prepared and lowered on to the turntable.  Mould linings and jackets.-In Fig. 2 a squaresectioned 2-part ingot mould is shown having a paper or plastics lining to retard cooling of the ingot. A cylindrical jacket 39 having two parts is clamped around the mould for mould rotation.
