JASON W. MIXTER, OF TEMPLETON, MASSACHUSETTS.
IMPROVEMENT IN SAW-GUMMERS.
Specification forming part of Letters Patent N0. 172,469, dated January 18, 1876; application led october 29,'1815.
To all whom it may concern:
Be it known that l, JASON W. MIXTER, of Templeton, in the .county of Worcester and State of Massachusetts, have invented a new and Improved Saw-Glimmer, of which the following` is a specification:
In the accompanying drawing illustrating my invention, Figure l represents a top View, and Figs. 2 and 3 are. side views, ot' my improved saw-gunnner.
Similar letters of reference indicate corresponding parts.
My invention relates to improvements in the saw-gu1nn1er for which Letters Patent have been granted to me under date ot' June 23, 1874, No. 152,302, so that the carriage, which is formed with a quadrantal slot at each end, is allowed to swing freely upon screws which pass through said slots and enter the main frame, admitting thereby the changing of the line of cut from the horizontal to the perpendicular without moving the cutter from its place, and without necessitating the readjustment ofthe machine.
In the drawing, A is the main or supporting frame of my saw-gumming machine, which is applied by means ot' strong clamping-jaws B and set-screws to the saw, being adjusted thereon by suitable gage-screws. The cuttershaft C is revolved by cranks at 011e or both sides in a carriage, D, that vslides in the centrallyrecessed way E, which is formed with a quadrantal slot, a, at each end, and is made adjustable to swing in either direction upon the setscrews, which pass through said slots and enter its main frame.
Heretofore, it has been necessary in changing the line of cut to carry the cutter away from the tooth, and adjust the whole machine again on the saw. This occasions not only loss of time, but prevents, also, by the limited adjustability of the carriage way, the gumming of small circular and of straight saws. By guiding the carriage-way E in such a man ner along the main frame A that both ends are free to swing around, the line of cut may be changed instantly Without moving the cut ter or readjusting the machine. This may be accomplished either by providing the carriageway with symmetrical quadrantal slots a and set-screws b, as shown in Fig. 3, or by making the carriage of circular shape, and moving it along flanged guides, with set-screws for adjusting the way to any required direction ot' cut. As the extreme positions of the way form an angle of ninety degrees the lines ot` cut maybe produced at any angle up to a right angle. The ready changing of the position ofthe way Eadmits the cutting at dit'- ferent angles without readjustlnent ot' the machine. The carriage-way E is further provided with a sliding gage-piece, F, that is set against the point ot' the tooth to be gummed, giving thereby, in connection with the gagescrews, the saine position to the gummer at each tooth. The feedscrew G has a set-nut, d, and jam-nut d', by which the distance to be cut or gummed may be defined exactly for each tooth. The cutter is run up as far as the screw allows, and is then moved to the next tooth, the gage F being placed against the point ofthe same. The guinlning is thereby accomplished evenly and exactly throughout the saw, and the operation ot' gumming the saw expedited and facilitated.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, in a saw-gummer,| of the swinging or adjustable carriage-way E, cutter C, and adjustable carriage D with the main frame A', all constructed and relatively arranged substantially as herein set forth.
2. The combination ofthe sliding gage-piece F, feed-screw G, and nuts d d with the carriage-Way E and frame A ot' a saW-gummer, as and for the purpose set forth.
