lUNrTED STATES PATENT lOrmea.
LINUS YALE, OF NEWPORT, NEV YORK.
IMPROVEMENT IN SAW-MILL DOGS.
Specification forming part of Letters Patent No. 2,196, dated July 29, 1811.
To all whom 'it may concern Be it known that I, LINUS YALE, of the town of Newport, in the county of Herkimer and State ot' New York, have invented a new and useful Improvementin vSelf-Setting Saw-Mill Dogs; and Ido hereby declare that the following is a full and exact description.
Upon that portion ofthe carriage of the sawmill called the head and tail block I bolt two cast-iron ways on the top, which lie parallel with the block, about eight inches apart, and reaching l'rom one end to the center of the block, made inthe following manner: The base is three inches wide and five-eighths of an inch thick. The upright portion is two inches high and the same thickness, with a tlange projecting from the top over the base about a half ot' oneineh square, to admita nutwith grooves in the ends to pass freely back and l'orth between the ways. This nut is made in two partsupper and lower-Gand bolted together, with a hole in the center two and a haltinches in diameter, containing a thread inside suitable to receive a screw, hereinafter described. This nut is six inches wide and nine inches long, the upper part lying on the top of the ways, and the lower part reaching at each end under the projections or flanges at the top ot' the ways, and forming, when bolted together, the grooves in the ends of the nut, as above described.
I make a screw of cast-iron, two and a half inehesin diameter and two feet and six inches lon fr. The thread on this screw is one inch wide and the space between the threads is one inch wide, causing it to drive the nut two inches t0 each revolution of the screw, which lies between the two ways and parallel with them, passing through the nut above described. The body of this screw projects over the end of the block about six inches, and is iitted to rea eeive a wheel, levers, Ste., having a journal lying in a box which is placed crosswise between the ends of the ways and bolted fast to the block, allowing the screw to revolve and drive the-nut back and forth between the ways.
On the screw, outside of and near thebox, is a wheel made fast to the body of the screw, six inches in diameter and one inch thick, having sixteen notches in its edge at equal distances apart. Outside of this wheel is a handlever, two feet and six inches long and one inch thick, having a hole through one end large enough to slip onto the body ofthe screw, which isthe i'ulcrum of the lever,lying at right angles with the screw and resting on a portion of the block in nearly a horizontal position. O11 the inside of this hand-lever, about three inches from the edge .of the wheel, is a horn or stud, of cast-iron, about one and a half inch long, onV which hangs a small iron hand ve inches long and one inch thick, which plays loose on the stud, and is secured by n small iron pin passing through the stud outside of the hand. The end of this iron hand is tted to thenotches in the wheel, and may he reversed at pleasure, by which the screw is made to revolve either way by moving the hand-lever. Outside of this hand-lever, on the body ofthe screw, hangs loose a self-setting lever, about twelve inches long and one inch thick, with an arm extending from the top and parallel with the hand-lever, about six inches in length, having its end turned under the hand-lever.
On the floor ot' the mill is pinned or bolted a piece of timber twelve feet long, two or three inches thick, and five or six incheshigh, lying parallel with the carriage, so that the self-set ting lever may pass near it as the carriage moves back and forth. Through this timber are holes one inch in diameter and eighteen inches apart to receive iron pins four inches long, which the selfsetting lever strikes when the carriage is passing back, by which means the hand-lever is raised and the screw turned one or more notches. After passing one pin the levers fall backinto their original position, the iron hand catches in another notch on the wheel, and is prepared to turn the screw in thc same` way until the log is moved the disi tance required, more or less of those pins being used to set different kinds of boards.
On each corner of the top ot' the nut on the end toward the log is an ear two inches wide and one inch thick, rising from the base about two inches. Through each of those ears is a hole in the center, about one inch in diameterl A wrought-iron halbail dog is so constructed that the lower ends are turned into these holes, which attaches it tothe nut, allowing it to swing back and fortha This dog is eight or nine inches high, and on the front side, at the top, are teeth projecting forward to hold the log. 0n the back side ofthe dog, at the top, is an eye, in which hangs a piece of wrought- A iron, about nine incheslong and three-fourths of an inch'squar'e.
On the top ot the nut, across the back end, opposite the dog, are grooves cut crosswise in the iron, into which the lower end ot' this piece ot' wrought-iron is driven sidewise to hold the dog fast in the log.
The above is a full and exact description of the machine on the block toward which the saw cuts, com monly called the tail-block. That part which is attached to the head-block is the'same, with the exception of thc selfsetting` lever, which is not used on the headblock, the hand-lever being moved by hand one notch on the wheel for every eighth ot' an inch the log is to move to set the board the thickness required. On one ot' those screws the thread runs one way and on the other the other way, called right7 and left. One is applied to the head and the other to the tail block, that the hand-lever may bear down to the head-block (when raised) to set the board, and the one on the tail-block may rise when it sets the board, that after being raised by the self-setting lever passing over the pin it may fall back into its original position, enabling the iron hand to catch in another notch in the wheel bef'ore it (the self-setting lever) strikes another pin in the timber on the tloor.
The screws are made in the following manner: The patterns are in two parts, divided in thecentcr lengthwise. One halt' is laid on the molding-hoard (or bottom of the Hash) the liat side down, the sand packed in the nowel, (or under part ofthe iiask,) which is then turned over, the board taken oft', and the other part of the pattern laid on, which is kept in its proper place by slight pins passing through one-half and a little distance into the other. The cope or upper part of the iiask is then set on and filled with sand and taken ott', (as in the ordinary way of molding to cast,) leaving one-halt' of the pattern in the upper and onehalt' in the lower part of the liask. Each half ot' the pattern is then carefully withdrawn from the sand and the flask closed, making, when the iron is poured in, a perfect screw without the expense of cutting the thread, as in the common way of making screws.
In addition to the former description of the ways, I cast one-half ot' the lower part of the box, in which thejournal ofthe screw lies, on
vone end of each way, which, when the ways are placedon the block meetin the center, forming the lower half ot' the box. The upper part or cap ot' the box'is laid across the journal and bolted through the ways each side ot' 'the screw.
)Vhat I claim as my invention, and desire to secure by Letters Patent, is not the principle of a screw, hand-lever, notched wheel,or iron hand, as others of a diiterent form have been used; but
I do claim- 1. The nut in combination with the wroughtiron dog, as herein described.-
2. The seltlsettingleverin combinationwith the hand-lever, notched wheel, and screw, for the purpose and in the manner sjecitied.
In testimony that the above is a full and exact description of the construction and use of the above-described machine as in-vented by me I have hereunto set my hand this 13th day ot' March, 18M.
LINUS YALE.
