The clock is an interesting design because Shelton has really turned the mechanism upside down, put the second hand at the bottom and the escape wheel is at the bottom so that it's an inverted deadbeat escapement right at the bottom of the clock, which usually of course the escapements are at the very top. So, here he's inverted the whole movement and the escape wheel is in line with the second hand there, a lovely deadbeat modelled on the same design which George Graham perfected. The escapement is called a deadbeat escapement because there's no recoil visible on the second hand. You can see it moves in increments from one second to the next, there's no recoil, hence the name deadbeat escapement.
