Description
UNITED STATES PATENT OFFICE.
D. V. THOMAS, OE RICHFIELD, NEW YORK.
MODE OF SETTING FOOT-BLOCKS OF SAWMILLS BY THE MOTION OF THE CARRIAGE.
Specification of Letters Patent No.
T0 all whom z' may concern.'
Be it known that I, D. V. THOMAS, of Richfield, in the county of Otsego and State of New York, have invented a new and useful Improvement in Sawmills, which I denominate The Self-Setting and Graging Tail-Block Slide, and I do hereby declare that the following is a full, clear, and exact description thereof, refrence being had to the accompanying drawing, making a part of this specification, in which- Figure l is a top view; Fig. 2 a side elevation; F ig. 3, detached parts.
The nature of my invention consists in an apparatus for setting and gaging the log by a slide, which is moved by running back the carriage in a manner here-after described The carriage of my sawmill should be constructed like those in common use; the tail block (a) is made similar to those that have a slide in them, a rabbet being formed on its upper forward edge, into which the slide (b) fits which sustains the log, it being fastened thereto by side dogs of the usual construction; on the under side of this slide a rack (c) is formed into which a pinion (cl Figs. 2, 3) works; the horizontal shaft of this pinion runs through the block (a.) at right angles to, and extending n out back of it having on the end a bevel pinion (e) which meshes into another bevel pinion (f) of the same size, at right angles t-o it on ashaft placed parallel to and in the rear of the tail block; this shaft eX- tends out on one side beyond the carriage and has attached to it a ratchet wheel (72.) a lever is also put onto this shaft which serves as its fulcrum; this lever has attached to it one or more pawls (7c) on its outer end working on the ratchet; the lever is also furnished with a set screw (Z) for the purpose 0f regulating the vibration of the lever 2,774, dated September 17, 1842.
which gages the thickness of the boards; `the shaft has also another lever on it-s outer end which hangs down below the carriage; l
from its inner side a stud (m) projects which when the lever is moved back bears against the underside of the lever and causes it to move the ratchet wheel; this lever (m) extends down low enough to strike the catches or buttons (fn) fastened to thefioor. This lever may be made longer or shorter which will tend to act more or less on the ratchet wheel. The buttons (n) are made to swivel on a pin so that they can be turned back when not in use.
When t-he carriage is run back the pendentlever (m) comes in contact with a projecting button (n) and is turned, which causes the stud (m) to act on the lever (i) and vibrate it; this by means of the pawls conveys motion through the ratchetand bevel wheels to the rack on the under side of the slide on which the log rests; when the carriage again runs forward the lever (m) is vibrated the other way without coming in cont-act with the lever, g the log can be gaged `to any thickness by means of the screw (Z) which allows the lever a greater or less vibration.
What I claim as my invention and desire to secure by Letters Patent is l. The lever (m) in combination with theV graduating lever hand (7c) and ratchet wheel (a) for the purpose and in the manner herein set forth.
2. I also claim the set screw (Z) for gaging the vibrations of the lever in combination with the above described apparatus.
I). V. THOMAS,
