SAW-GUIDE.
{SPECIFICATION forming part of Letters Patent No. 295,792, dated March 25, 18841 Application filed March 17, 1883. (No model.)
To all whom, it may concern.-
The arms A B have round shanks fitted into Be it known that I, THOMAS J. NEAGY, of the end holes in the sliding block G, so as to Milwaukee, in the county of Milwaukee and I slide or turn therein. The arm B extends be- State of \Visconsin. have invented certain new and useful Improvements in Saw-Guides; and I do hereby declare that the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to whichit pertains to make and use the same, reference being had to the accompanying draw ings, and to the letters of reference marked thereon, which form a part of this specification.
M yinvention relates to saw guides; and it consists, essentially, of a novel construction and arrangement of the parts, whereby either arm may be adjust-ed independently or both arms moved laterally without changing their relative positions, and whereby the outer arm may be radially turned back so as to permit of the changing or removal of the saw.
In the accompanying drawings like letters refer to the same parts in each figure.
Figure 1 is a perspective view of my improved guide. Fig. 2 is a view of the gearcase with the end plate removed. Fig. 3 is a longitudinal vertical section of the guide on the line 2 2, Fig. 1. Fig. l is a transverse vertical section of the same on the line 1 1, Fig. 1; and Fig. 5 is a view of the end of the guide toward the saw.
O O is the bed-plate, provided with slots I I at each end, to receive bolts by which the guide is secured-to the saw-frame, and which permit .of its adaptation to saws of different sizes.
G Gis an iron block, provided at each end with transverse holes, into which are fitted the shanks of the arms or jaws A and B. It has also a central threaded perforation passing through it from side to si de,to receive the adjusting-screw F, by which it may be moved laterally upon the dovetailed way 0, raised on the. bed-plate G.
H is a gear-case made upon a leaf project ing rearwardly from the center of the bedplate 'O. It furnishes bearings for and inclosesthe worm-wheel P and pinion N on the shank of screw F.
d d are bolts holding the gear-case together.
yond the block G, and has an eye in its end toward the saw, while the arm A is bent at right angles and provided with a corresponding eye, which, when the arm is in its horizontal position, is directly opposite the eye in arm B.
a a aresmall pins or blocks of wood or other suit-able material, inserted in the eyes in the ends of the arms A and B in such manner as to present their ends to the sides of the saw just inside of the teeth when the machine is in proper adjustment. To remove or change saws, the arm A is turned back, as shown in Fig. 3. \Vhen thrown forward, it is arrested and held in the position shown in Figs. 1 and 4 by the lug h, which strikes and rests upon shoulder g on block G, the arm A being secured in position by nut and washer K. The inner end of the arm B is turned down, and provided with the threaded sleeve E, which is formed at its protruding end into the square shank L, so as to be turned with a wrench in the adjustment of the arm, which turns freely therein, but partakes of its longitudinal movement as the sleeve is turned in or out. A portion of the hole through which the arm B passes is threaded to receive the threaded sleeve E. i
D D are set-screws, by which the arms are secured in place when properly adjusted. The shanks of the arms have a flattened part, m, against which the set-screws are depressed.
0 is a gib inserted between the side of the dovetailed way 0 and the groove in the block G; and b b are small wedges placed in vertical openings in block G at one side of the way 0, and having threaded spindles extending above the block, and provided with nuts, by which the gib may be drawn snugly up against the way 0, and thereby any wear taken up. The arm A is held in its horizontal position by the lug h, which is raised upon its shankclose to block G, and rests upon shoulder g, projecting from the front of block G.
f is a small rod or shaft, secured in the center of worm-wheel P, and provided with a bracketbearing, a n, which is attached to some convenient part of the saw-frame. To the end of operator. I
rodf is attached the small hand-wheel M, by l means of which the screw F is operated, and the block G, with its arms moved in or out while the saw is in motion without danger therefrom to the operator. The screw F is provided with a square head, 6, whereby it may be turned with a wrench whenever it is :found convenient to. dispense with the worm P and hand-wheel M.
My improved guide operates as follows: The bed-plate 0 having been adjusted so that the pins a a come just inside of the teeth on the saw, the pin in arm A is brought close up to the side of the saw by turning the screw F, operating block G. The pin in arm Bis then brought close up to the other side of the saw, by means of the threaded sleeve E, and both arms are then secured in position by the setscrews D D, and they may be carried with the block G to either side, and the saw thereby gaged to run with great accuracy.
The entire adjustment may be made while the saw is in motion, without danger to the I claim" 1. In a saw-guide, the combination of the laterally adjustable block G, right-angled arm A, pivotedin block G,'straight arm B, provided with threaded adjusting-sleer e E, bedplate 0, provided with transverse dovetailed way 0, gib c, wedges b I), worm P, and screw F, provided with pinion N, substantially as and for the purposes set forth.
2. In a saw-guide, the combination of the block G, adapted to move transversely upon the dovetailed way 0, raised on the bed plate O, bed-plate 0, arms A and B, screw F, pro= vided with the pinion N, worm-wheel P, and rod f, provided with hand-wheel M, substantially as and for the purposes set forth.
3. The combination, in a saw-guide, of the arm-A, provided with the lug h, arm B, provided with the threaded sleeve E, block G, adapted to move transversely upon the dovetailed way 0, raised on the top of bed-plate O, and provided with the shoulder g, setscrews D D, bed-plate C, with the gear-case H, inclosing the worm-wheel P and the pinion N, and
the screw F, substantially as and for the purposes set forth.
4. In a saw-guide, the combination of the block G, provided with the right-angled arm A and the adjustable arm B, and capable of lateral movement upon the bed-plate O, and screwF, having a fixed bearing in an extension from the rear edge of bed-plate O, substantially as and for the purposes set forth.
7 In testimony that I claim the foregoing as my own I aiiix my signature in presence oftwo witnesses.
