Description

UNITED STATES PATENT N OFFICE.
or oAMDEN, omo.
IN sAwMILLs.
Specification of Letters Patent No. 8,942, dated April 15, 1851.
To all whomz'tmay concern:
Be it known that I, JOHN W. `RoINs, of Camden, `Preble county, Ohio, have invented new and `useful Improvements j in Sawmill-Dogs; and I do hereby declare the following to be afull, clear, and eXact description of the same, reference being had to the annexed drawings, making `part of this specification, Figure .l being a perspective View and Fig. 2 a birds-eye view of a saw` frame, &c., with my dogs attached.
The object of my invention `is to provide a simple and easily arranged apparatus by which the log may be shifted a certain exact distance at each end between each consecutivecut.
The saw (a), saw-gate (b), mill frame (c), carriages (e, t,), not diering from those ordinarily employed need no particular description here. j
The front end ofthe log is adjusted by the following mechanism. Upon the forward carriage (e) is a projection (f) which affords a socket for a set screw (g) which is rotatedbya crank (71,); in a line with the set screwis a bolt (gf) which traverses in a socket (f) by the impingment of the set screw upon it. `At the other end of the bolt (g) is a head or dog (i), which affords when thrown down and against the face of the log, the readymeans of adjusting the width of cut which is 'first of all determined by the set screw. The log is then held in position by the dog (j) after the cut, the head` is raised, forced out somewhat, and the tongue of the head brought down within the kerf just made. The log is then moved for another cut by `bringing its new face in contact with the tongue of the head (i), when it will have traversed laterally precisely the width of the sawn board and the kerf just made; being then dogged again by (j) it is so far as regards this end of the log, ready for ano-ther cut.
The rear adjustment is as follows: the variation being necessary from the absence of a kerf for the insertion of the tongue of the dog. Upon the transom (e) is a pro-` jection (7c) which affords a socket for a set screw (Z), rotated by a crank (m), which screw impinges upon the end of a boltl (n) which traverses in a socket (0);
this bolthas `at itsfother enda dog (p). This bolt and dog (p) which vibrate together, have alateral adjustability between the end of the set screw and a stationaryblock (g) whichis attached to the transom. When the log is first placed in position on the carriages the dog (p) is driven home into it; after the cut, the log carrying the dog (p) along with it is shift `ed laterally until it is brought up by the contact of the dog (p) with the block (g) g thus the space between the end of theset screw and the bolt thenthe dog is in contact with the block (g) is the determined width of the board less the kerf. The dog is thrown back and placed in its former position ready for determining the next cut.
The wedge (s) between the rear carriage (t) I and the under side of the block (g) which is stationary and attached to the transom (c) holds the carriage firmly in the intervals of cutting. Ihe dogs (r,r,) hold the log to the carriage.
Having thus fully clearly andeXactly described the nature and operation of my in` vention what I claim therein as new and desire to secure by Letters Patent isl. The vibrating dog having the disl/tan-ce of its head or tongue (i) with respect to the saw, adjustable laterally by a seta-screw (g) substantially as representedso that by placing the tongue of the head in each successive kerf and bringingthe face `of the log in contact therewith, the thickness of each consecutive board is exactly counterpart with the irst.
2. I claim, for analogous purposes at the rear end of the log which is `destitute `of a kerf, the vibrating dog (p) whose distance in respect to the stationaryblock (g) is adjustable by means of a set screw (Z), the range between the head of the dog and the block affording an easy and determinate means of `giving exactly the same thickness to the boards at the rear end of the log.
In testimony whereof, I have hereunto set my hand before two subscribing witnesses.
JOHN WV. ROBBINS.
