Improvement in mechanical movements
|
Ambrose Webster |
Waltham, MA |
This mechanism provides a pair of arms that reciprocate through the arc of a circle, and move at a varying rate. The specification does not give any hints as to what this mechanism is for, but given the inventor's connection with what would become the American Watch Tool Co., it seems likely that it was invented for use in watches and clocks. |

|
Ambrose Webster |

Ambrose Waltham was president of the American Watch Tool Co. We are not sure who made this grinding machine, but American Watch Tool Co. had the capacity to do it and almost certainly used this machine in the manufacture of their Whitcomb lathes.
Abstract:
The machine of this invention, in substance, is composed of a horizontal carrier for the lathe-bed to be ground, which is arranged and adapted otherwise to travel horizontally on and along a suitable stationary support and guideway, appliances to secure the lathe-bed on said carrier and to have its top and opposite side oblique faces exposed, appliances to move said carrier along its said support and guideway, and a circular grinding lap or laps for grinding the lathe-bed, and which are arranged and adapted otherwise to be continuously rotated, and under rotation to be presented to the said exposed surfaces of the lathe-bed to he ground by them, and which lathe-bed is fed forward to them by the movement of its carrier.
Claim:
In a machine for grinding lathe-beds, in combination, a carrier for the lathe-bed to be ground, and appliances held on and for securing it to the carrier, consisting of jaws E & E2 at its opposite ends, each adapted to be engaged with and disengaged from and to draw it down onto the carrier. |
