This is a prototype of an escapement that I want to put in a watch movement. It is equivalent to an anchor escapement, except the pallets are made of pins instead of having special shapes. It is also equivalent to a verge escapement, except the verge is in the same axis as the balance wheel instead of perpendicular. I haven't seen an escapement like this before, but I am sure it has been tried as it is so obvious. Probably it is not used because the amplitude (rotation of the balance wheel) is so low, here only about 8.6 degrees at the start and 8.2 degrees at the end. A typical modern watch movement has amplitude around 300 degrees! Usually a watch uses a "Swiss lever" escapement, in which the balance wheel is left free to spin on its own for almost the entire cycle, only interacting with the escape wheel through the pallet fork, which gets locked to the banking by the "draw" of the escape wheel while it's not interacting with the balance wheel. The advantage of the Swiss lever escapement is that the balance wheel can swing at its natural rate, and isn't impeded so much by how much torque is being applied to it. The disadvantage is that the pallet fork is a tiny part that you have to make very precisely. I'd rather have a less accurate escapement that is easier to make. ... https://www.youtube.com/watch?v=RApdxL61nmA

Now with much more weight on the foliot. This increases the moment of inertia of the foliot which makes it accelerate/decelerate more gradually. ... https://www.youtube.com/watch?v=vMlZrNXFCKA
