Bridgeport, Fairfield County, CT |
Wooster & Smith - patent attorneys
Abstract:
Our invention relates to certain novel and useful improvements in machines for planing metal, and has for its object to impart motion from the driving-pulleys to the mechanism which effects the movements of the table by positive and uniform means, while at the same time the arrangement of the pulleys may be more convenient, and all unnecessary rattling noise common to planers done away with.
Claim:
The combination, with a metal planer, having an obliquely arranged shaft provided with a spirally-toothed pinion meshing with a rack in the table and a spur-wheel on its outer extremity, of a transversely arranged driving-shaft, having a spirally-toothed pinion meshing with said spur-wheel. |

This patent was improved by patent #421,514.
Abstract:
My invention relates to certain novel and useful improvements in that class of machines known as hat-finishing lathes, and has for its object to do away with all vertical movement of the hat-block, and to so construct and arrange the sandpapering mechanism that it will be adapted to the varying distance of the external contour of the hat-body from the center of revolution; also, to provide means whereby the hat-block may be securely held in position on the revolving shaft; and, furthermore, to enable the sandpaper or other rubbing-surface to act on the hat with a continuous and uniform movement and pressure, whereby not only a great saving of sand paper is effected, but also much time and labor are saved which would otherwise be consumed in tearing and utilizing said paper in suitable strips.
Claim:
In a hat lathe, the mechanism attached to the shaft which supports the hat-block, adapted to revolve in its-bearings without any vertical play, in combination with means for sandpapering the hat and mechanism for causing said means to act on the hat in different horizontal planes at different times. |

Metal Planing Machine
|
Edward P. Walter |
Bridgeport, Fairfield County, CT |
Abstract:
Our invention relates to certain novel and useful improvements in machines for planing metal, but more especially to that particular mechanism of said machines which, controls and regulates the slide of the table, and has for its object to provide means for controlling the movement of said table, whereby the latter may slide beyond the working limit for the purpose of examining or changing the work without shifting the shipping-blocks or lifting the table, and thereby throwing it out of gear, while at the same time it is not necessary for the workman to remove the stop from between the shipping-blocks.
Claim:
In a planing-machine, the mechanism which reverses the movement of the table, in combination with the shaft having secured thereon the crank-arm, the shoulders cast integral with and the stop pivoted to said crank-arm, and the shipping-blocks arranged on the table. |

Hat Finishing Lathe
|
Charles H. Reid |
Danbury, Fairfield County, CT |
Abstract:
My invention relates to certain new and useful improvements in hat-finishing lathes, and has for its object to improve on the construction shown and described in Letters Patent No. 301,279, granted to me on the 1st day of July, 1884, and to render the movements of the sandpapering mechanism in such machine universal and entirely automatic.
Claim:
n a hat-finishing lathe, the combination, with the hat-block and templet mounted on the power-shaft, of the sandpapering mechanism carried by a rockshaft and means, as a system of levers connected to said power and rock shafts, whereby the latter is automatically operated, |
