SAW GUARD Filed' March 17, 1941 A 2 Shvee'ts-Shet 2 *f2 Inval-1in? Flttnr'n'eg Patented Mar. 9, 1943 SAW GUARD Mark Uremovich, Milwaukee, Wis. Application March 17, 1941, serial No. 383,746

1 claim. (o1. 143-159) 'I'his invention appertains to rotary bench saws, and more particularly to a guard for the saw blade.

One of the primary objectsof my invention is to provide a guard for circular saws which will be of an exceptionally simple and durable construction, and which can be readily applied to the table of a bench saw, and which will permit the fine adjustment of the work gauge block relative to the saw blade.

Another salient object of my invention is to provide a guard for saws which is freely suspended above the table and saw, and which can be readily swung entirely out of the way and to one side of the table when the use thereof is not desired.

A further important object of my invention is to provide a guard for saws movable with the work, and which is so suspended above the saw and table that the Work can be brought into engagement with `the saw from either end of the table.

A still further object of my invention is to provide a saw guard including a swinging frame mounted above the table, and depending rock levers to which the guard per se is connected by movable links, whereby the guard can be easily tilted from eitherv end of the saw blade, and whereby the guard can be shifted or raised in a direct vertical path.

With these and other objects in View, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a top plan View showing my novel guard applied to the table of a bench saw, parts of the figure being shown broken away and in section.

Figure 2 is a transverse, sectional view taken on the line 2-2 of Figure 1, looking in the direction of the arrows, and showing the operative position of the guard in full lines and the inoperative position thereof in dotted lines.

Figure 3 is a longitudinal, sectional view through the sawing machine, showing my guard in its complete lowered position.

Figure 4 is a View similar to Figure 3, showing the guard tilted as the work is introduced from one end of the sawing machine.

Figure 5 is a view similar to Figure 4, and showing the guard in a raised, elevated position during the passage of the work over the saw table.

LFigure 6 is an enlarged, fragmentary, detail, vertical sectional view taken on the line I-B of Figure 3 looking in the direction of the arrows, illustrating the mounting for one end of the guard.

Figure 7 is a detail, sectional view taken on the line 1 -'I of Figure 3, looking in the direction of the arrows, and illustrating a detail of construction.

Figure 8 is a detail, sectional View through the guard per se, taken on the line 8-8 of Figure 3 looking in the direction of the arrows.

Figure 9 is a detail, sectional View similar to Figure 8, but taken on the line 9-9 of Figure 3v looking in the direction of the arrows.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter S indicates a sawing machine, and G my novel guard therefor.

The sawing machine S can be of the typ shown in my pending application Serial No. 332,317, led April 29, 1940, and, hence, the same includes a Work table I0 having a slot I I through which projects the power-driven circular saw blade I2'. Movably mounted on the table I0 toward and away from the saw I2 is the work gauge block I3.

My novel guard G includes a swinging supporting Vframe IISy for the guard shield I6. This shield I6 encompasses the saw and is suspended from the frame I5 in a novel manner, as will be later set forth.

The frame I'5 can take various characters, but by referring to Figure 1, it can be seen that the same takes an H-shape when viewed in top plan. Thus, in the present instance, the frame includes spaced, parallel side bars I'I and I8, and a connecting crossbar I9.

The frame I5 is mounted for swinging movement on the table, whereby the guard shield can be readily moved into and out of an operative position relative to the blade. To permit the swinging of the guard shield I6, the terminals of the bar I8 are provided with hinge Dintles 20, which are rockably mounted in bearing openings formed in the upper ends of standards 2I. These standards 2| are firmly bolted, as at 22, to one side of the work table ID. The bar I8, adjacent to each end thereof, carries outwardly projecting stop lugs 24, and these lugs are adapted to engage either side of the standards, according to the position of the frame, to limit the downward swinging movement of the frame, and

Vpins 38.

so that the frame will lie in a horizontal position.

The guard shield IB includes a pair of substantially semi-circular plates 25 and 26, held in proper spaced relation by a plurality of spacing blocks -21. Suitable fastening elements extend through the plates 25 and 26 and the blocks 21, and the plates are adapted to lie on opposite sides of the saw blade I2 when the guard is in its operative position.

Projecting outwardly from the opposite ends of the plates 25 and 26 are upturned, arcuate guide fingers 28, and these fingers serve as means for facilitating the insertion of the work under the guard shield, and the lifting of the guard shield incident to the sawing of said work. The Y outer ends of the fingers 28 receive therebetween a filler or spacing block 29, as can be readily seen by referring to Figure 1.

The guard shield I5 is suspended from the frame in. a novel manner, as now will be described. The ends of the front bar I1 have firmly secured thereto supporting brackets 30, and the upper ends of these brackets have formed thereon bearings 3I for receiving the pivot pins 32, which unite the upper swinging levers 33 of a pair of toggle levers 34. The upper levers 33 of each toggle have formed thereon depending pivot ears 35 for receiving pivot pins 36, which unite the lower levers or links 31 of the toggles with Vthe upper levers 33. The lower ends of the links 31 are pivotally connected to the guard shield I6 adjacent to the opposite ends thereof by pivot A relatively long steadying link 39 is employed for the shield, and one end of the link 39 is pivotally connected to the upper end of the shield adjacent to its center, and the upper end of the link 39 is pivotally connected to oneof the bearings 3|.

In operation of my guard, it can be seen that as the work is slid toward the saw I2 from either end of the work table, the work will engage the arcuate guide Vlingers 28, and the guide shield I6 will be initially tilted to a position shown in Figure 4. As the work isV further advanced past the saw, the guard shield will be completely raised, as clearly shown in Figure 5. As the work leaves the saw and shield, one end of the shield will lower, and when the work completely Vleaves the shield, the guide ngers will ride down the work, and the shield will lowergradually over the work. Y

Thus, it can be seen that the saw is sufficiently protected at all times. That is, the shield is guided both during the initial engagement of the work with the saw, and during the time the work leaves the saw. When there is no need for the work table to the dotted line position shown in Figure 2.

Changes in details may be made without departing from the spirit or the scope of my invention, but what I claim as new is:

In a bench saw including a work table and a Vcircular' saw partially projecting above the Aworking face of said table, a guard for said saw including a supporting frame arranged above the table and saw, a guard shield receiving the projecting portion of the saw, means freely suspending the shield from said frame including toggles arranged at each end of the frame, each ofsaid toggles including upper and lower pivotally connected links, means pivotally connecting the upper links to the frame, means pivotally connecting the lower` links to thev shield adjacent the opposite ends thereof, and-a steadying link pivotally connected at one end to the frame and pivotally connected at its opposite end to the upper end of the Vshield between said toggles and adjacent to the center of said shield.
