Lathe-chuck
|
William L. Sweetland |
Windsor Locks, CT |
This chuck is a 'universal' chuck where the jaws can be moved either together or independently. The description of patent 346,133 describes this patent: "...the jaws are capable of being disconnected from the motive gear by which their universal movement is effected, whereupon each jaw may be propelled outward or inward by its own screw. When it is desired the render the chuck universal again, all the jaws must be set to positions equally distant from the center, whereon they are reconnected to the motive gear. The motive gear in this kind of chuck is most commonly an annular rack engaging pinions on the radial screws which propel the jaws. The well-known 'Sweetland' chuck is an example..." The 'Westcott' chuck is also a universal design, but it uses jaws riding in boxes that engage with a helical ring, and each jaw is connected to its box by a screw that may be independently adjusted to move that jaw relative to the others. |

Abstract:
My invention relates to devices for marking or laying out and measuring key-seats, grooves, slot-ways, or rabbets upon rounded surfaces of wood or metal.
My object is to provide anew and improved device for marking or laying out and measuring key-seats, grooves, slotways, or rabbets in or upon rounded surfaces before they are cut out, and which will fit upon any rounded surface at any point between the ends of the shaft, and can be operated to lay out the length and width of the key-seat, groove slot-way, or rabbet before it is cut, and to measure the accuracy of the work done, which is adapted to use straight-edges of varying lengths or width, or any width, and can be adjusted to different lengths, as well as to fit a large bar or a small rod.
Claims:
1. The combination of the clamps consisting of a bracket having an angular lower arm and a top flange, a set-screw through the flange, a movable jaw-piece fitting over the lower arm, and straight-edges secured therein at an angle to each other.
2. The combination of the clamps consisting of a bracket, a rigid jaw upon its lower side, a movable jaw concaved to fit upon the lower jaw, a set-screw connected to the movable jaw and actuating it, and straightedges secured between the jaws.
