MR. JAMES FROST and sons, (SUTTON- 
STREET, CLERKENWELL,) for an zim- 
provement on Cocks, or an improved 
Lock-cock. i ; 
HE invention consists in this: In- 
stead of making the pin or revol- 
ying piece of the improved lock-cock, 
solid throughout, excepting that part in 
which the aperture, or channel, is made 
for the hquor to pass through, they make 
a cavity in the upper. part of the said 
pin, or revolving-piece between the cross 
or handle, ring, or other termination 
made use of for moving the said pins 
or revolving-piece and socket, into which 
the said pin or revolving-piece is fitted, 
by turning and grinding, and in. the 
cavity so madea lock, having a bolt, 
is fixed, and likewise the other parts, 
usually constituting such as operate by 
means of a bolt; and the said bolt ts 
thrown backwards and forwards, by a 
motion at right angles to the axis of the 
pin, by the action of the key, in order 
that when the said bolt shall be protru- 
ded, or shot out of its cell, in the manner 
of locking, part of the bolt shall stand 
forward beyond the face of the pin, or 
revolving-piece, and shall enter into a 
cavity in part of the motionless socket, 
into which the pin is placed, and shall 
thereby render the said pin itself mo- 
tionless, and shall make it impracticable 
to turn or open the cock, until the bolt 
shall have been first shot back by means 
of its key: the whole is so formed that 
the water-way or course through the 
cock shall be shut, whenever the said 
bolt is or shail be protruded in the man- 
ner of locking into the said motionless 
socket, and shall not be capable of being 
opened until the bolt is withdrawn. It 
is farther observed, that this improve- 
ment on cocks may be applied to any 
Kind or description of cock, and to the 
lower as well as, or instead of, to the 
upper part of the said pin or revolving- 
piece, and. the bolt may also, when pre- 
ferred, be made to shooc- or lock into a 
fixed or motionless piece, preceeding 
from the vessel or receptacle, in which 
avy liquor or Muid is to be guarded and 
. 
secured by the said improvement, as well 
as into a fixed or motionless piece, suc 
as has been described; and that the 
effect of the last-mentioned disposition: 
and application of the bolt with regard 
to the said vessel or receptacle will be 
such, as not only to prevent the pir 
from revolving, with regard or in relation, 
to the cock itself, but likewise to” pre- 
vent the said cock, whilst locked, from 
being unscrewed or drawn out of the 
vessel, ‘

**My method,” says the patentee, 
“of manufacturing boots and shoes, con= 
sists in closing or sewing the upper part 
of boots and shoes with hemp, in the 
usual way, or with wire made of iron, 
steel, brass, copper, tin, or any other
