' SAW-GUMMEFL' SPECIFICATION forming part of Letters Patent No. 290,947, dated December 25, 1883.
Application filed January 13,18F3.
To all whom it m/m concern.-
Be it known that I, GEORGE VAN NOSTRAND, a citizen of the United States, residing at- Gloversville, in the county of ,Fulton and State of New York, have invented certain new and useful Improvements in Saw-Gummers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
Figure 1 of the drawings is a representation of a plan view of my saw-gummer. Fig. 2 is a side view. Fig. 3 is a bottom View,
. and Fig. i is a cross-sectional view of the same.
This invention has relation to machines for gumming saws; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and pointed out in the claim appended.
In the accompanying drawings, the letter A designates the main clamp,which is formed with the cleft bearings a in its branches B, for the saw. Set-screws b are provided to hold the saw, and threaded bearings 0' to re- 0 eeive the screws that regulate the position of the teeth, so that the action of the burr lwill be uniform. The points of the screws 0 0 come against the back edge of the saw, to adjust the saw and present the teeth evenly to the burr G. The branches of the main clamp are connected by transverse bars 0 and D, whereof the former, G, is provided with a guidelug or flange, d, which is designed to engage a groove-bearing, e, of the shaft-carrier E. One of the branches B of the main clamp is provided with a back bearing, g, to which is secured an arm, h, carrying a roller, 70. The bearing 9 is also provided with areg-. ulatingscrew, Z, the end of which is swiveled in the shaft-carrier, and serves to regulate the position of the latter with reference to the main clamp. The shaft-carrier E is formed with a longitudinal body-bar, m, having arms a projecting from its ends, and perforated for the passage of the arms 10 and q of the longitudinal shaft I*, which carries the long burr 0r cutter G. The arms of the shaft are respectively provided with right-hand and lefthand threads. The arms n of the shaft-can rier are channeled, as indicated at 1*, to re- (No model.)
eeive the hinged bars 3 and if, having a halfnut formed in each for the purpose of engag ing with the screw-shaft, the threads on the half nuts corresponding to those on the shaft. These half-nuts may be locked, when thrown into engagement with the screw-shaft, by means of a pin or bolt, a, passing through holes in the arms a and the free ends of said bars, the other ends of the bars working on pivotpins '0. These hinged bars are designed to be used alternately, one being thrown out of engagement while the other is at work. The back bar,m, of the shaft-carrier is provided with a slot or opening, a, through which ex tends the arm 71., carrying the roller 7a. In front of this roller,through slots b in the arms a of the shaft-carrier, extends a bar, II. This bar His provided with a head, H, which is connected to the end of the arm 19 of the shaft. so that when said shaft is turned the bar H will move longitudinally in front of the roller. In the edge of the bar H next to the roller is made a recess or seat, K, designed to receive a re movable wedge, in. As the shaft is turned to operate the burr, the latter is not only rotated, but also moved longitudinally in a reg ular and uniform manner. At the same time the wedge, moving longitudinally with the bar H, slides against the roller of the main clamp, so that the shaft-carrier is forcibly moved forward, crowding the burr into the saw. The shaft is provided with a crank handleat eaeh'end, so that the instrument can be operated with facility. As the burr is fed longitudinally as well as into the metal of the saw, the labor of operating the instrument after adjustment consists only in turn ing the crank of the burr-shaft.
'Having described this invention, what I claim, and desire to secure by Letters Patent, 1s
A saw-gumming machine having its burrshaft provided with right and left hand threads, and the shaft-carrier provided with In testimony whereof I affix my signature in presence of two witnesses.
