Letters Patent No. 94,148, dated ,August 24, 1869.

y -IMPROVEMENT IN CLOCK-ESCAPBMEN'IF'.

The Schedule referred to`in 'these Letters Patent and making part of. the name.

and I do hereby declare that the following is a full,

clear,and exact description of'the construction and `operation of the same, reference being had to the accompanying drawings, making a part f this'specification, in'which-v Figure l is a front view. -Figure 2 is a similar view, representing a slight modihcation.

The' object of this'invention is to improve the pendulum-escapement of a clock, in such a manner as tov diminish the rigidity and consequent friction of the working-parts, and to secure greater smoothness'alid uniformity of action, and more ready and perfect adjustability.

In the drawings- A is vtbe supporting-plate.

4B, the* escapement-wheel. I

B, the pendulum-rod.- v

m, the lower jaw ofthe pallet, articulated, at e, to a bent rod, i, and a' raised `bed or plate, a, attached to the large plate A. .l v

. a, the upper jaw of the pallet, articulated, at e', to a bent rod, t', and a raised bed or plate, a', also attached toplate A. v

R is a rod, rigidly attached to the' lower jaw, and

looped at r and Ir; andv S is a rod' rigidly attahed to the upper jaw, bent soas to work without coming in contact with the parts 'i i', and provided with a spur, s, which projects into the loop fr, so that as the pendulum, extendingthrough the lower loop/r', oscillates the rod It, th'eflattr, in its ti'irnfoscillates the rod S, and the two jaws m n are caused to operate properly in connection with the teeth ofthe escapement-wheel.

-It is evident, that'by bending eitherthe rod R or S slightly, the jaws of the pallet can be caused to assume different inclinations to the escapementwhee l, and the actionof the apparatus can be adjusted-at pleasure.

It is further evident, that by supporting and pivoting the jaws independently of each other, and connecting them bythe slightly-elastic rods, the rigidity of the parts is so overcome that their whole action will be rendered more smooth, easy, and uniform than heretofore.

Having thus described my'inventiou,

What I claim as new, and desire to secure by Letters Patent, isv The combination of the two jaws, constructed, pivoted, and operating as herein described, with the rods R S, or their mechanical equivalents, whereby the rods are connected to each other and to the pendulum, substanti-all y Vas described.
