K
www prone part of the Cock is the Lever for lifting the Main Spring G. The Main Spring has at the end of it for where the Metal begins to take its bend; a
so as to keep out the Weather at the time of its action on the top of the Mainspring The Pan from the outside to the Barrel a gentle descent to make the Powdermore readely communicate with that in the Chamber The Sear L which holds at the half and full Cock und which in the Locks now in Use
is forced into the Nitch by the Sear Spring is very differently peformed in mine The Spring is placed on a stationary Pin at the end of that Part of theinner Plate nearest to the Murale M this Spring,NN, we sawed nearly into two the bottom one the broadest and which forces the Sear to take hold
at the half and full Cock The Sear drops on a Center Pin 0, a little beyond the back part of the Cock and in the outer Plate is a fixt Pin Pon which is placed a solid bit of Metal or Bolt Qand which is conducted into the flat piece of Metal, the Upper Fart of the Cock, R, that is cut away on
purpose to receive it by the Upper Spring of the one already mentioned, NN that carries the Sear to the half Cock They are forced to their Work by a movable Pin, S at the back of them put into the two Plates The Cock is then so firmly belied that it is impossible to go off at the half Cock this
Bolt takes hold at the same instant that the Cock is on the half Cock when moving the Cock to the full Cack the angular part of the Metal, T, which touches the top of the Bolt presses it away for discharging which is effected by a small bit of Metal standing in the top of the Sear Uand a piece of
which comes downward at nearly right Angles from the end of the Bolt V the Trigger being touched these two Pieces come in Contect and hold away the Bot till the Cock has gone down on the Hummer which is the only way it can be discharged triffim a Blow on the Cock it is sent off even at the time
it is on the full Cock the Bolt Spring already explained will conduct the Bolt into its place and will catch it at the half Cock H The Provision for turning the Flint is as follows between the two great Checks, WW for holding the Flint the upper one of which moves as usual by the Screw Xas in those now in
use are placed two other smaller Checks YY the lower one has in the bottom of it a point, Z as a enter and which goes into a Cone in the bottom great theic W In the back part of this lesser bottom Check, Yare teeth 2.extending about half way round it. Just above these Teeth is an upright bit of Metal

great Cheek W is then screwed down which holds the little ones on the Flint, it has its motion from an eulless Screw 7, On each side of the large lowergreat Cheek, Ware two small pieces of metal 88 m which the emilles Screw is mounted the thread of it goes into the Teeth cut at the back of
the little bottom Cheek Valready described by this means the Flint has a circular motion to the right and left, The Drawings represent every distinct part of the Lock and a view of it put together, also a Represention of the appearance of the Bolt before being put on the half Cock, 9, and is situation
at the full Cock 10 a View of the Hammer thrown up, 11 at the of the entless screw is a large milled headded Button, 12 for more easily moving of it. The inade Plate B of the Lock is fitted so as to go under the Pan and Boxes up the whole of it and is kept fast by two hook BB turning down on two
