Forming part of' this slot, and extending at right angles to it, is a shorter slot, 7, in which a tile, S, is secured by means of a set-screw, 9. Extending through the side of the bar c into the slot 6 are two or more setscrews, t', which regulate the width of the slot according to the thickness of the saw, so that in working the le back and forth, for the purpose ot dressing oft' the points ofthe teeth after they have been upset, it may move perfectly straight and even.
Having thus described my invention, I claim- A device for jointing long saws, consisting ofthe slotted iile-hoider a, having legs to form au extended bearing on both sides ofthe sawblade, and provided with set-screws t9, as shown and described.
In testimony that I claim the foregoing lV have hereunto set my hand this 22d day ot July, 1873.
