SAW GUARD Filed Oct. 51, 1928 2 Sheets-Shee l Sept. 2, 1930. 1,774,521

W. S. NEIGHBOUR SAW GUARD Filed Oct. 31, 1928 2 ShOGtS-Sheai 2 I Qwuwntox;

' falls on each side of the saw after the manner of wings, and forms a partial enclosure for the forward part of the saw when in initial lowered position. It is formed with an integral forwardly and upwardly inclined toe 22, having a curved lower face convergent toward the top of the table and toward the rear at a progressively reduced angle, the extreme forward part when the device rests upon the table having a suitable angle with respect to the table to permit stock to be readily pressed rearwardly thereunder so as to cause the guard member to ride upon the timber and be lifted, permitting the timber to engage the saw. The forward extremity of the toe is preferably located at or slightly below the highest level of the saw, so that in case a timber is fed to the saw which is too thi k to be cut thereby the toe will abruptly strike the end or side of the timber and prevent further movement of the latter un less the guard is lifted. so that the operator will have notice of the extra thickness. The sides of the rear guard member 15 are recessed to a depth corresponding to the thickness of the cars 21 of the front guard memb r, so that the sides of both guard members lie in the same plane and as nearly flush as possible. It is important to note that the joining portion between the two sides of the member 20 at the top edge is extended rearwardly toward the pivot to such distance that when the toe of the front guard is lifted and the guard moved rearwardly, the top edge 17 of the rear guard will strike against the joining portion and check such rearward movement of the front guard when its center of gravity has just passed dead center with respect to the pin 14:. As a result, the front guard may be manually lifted and moved into inoperative position\ where it will remain while a timber is brought into engagement with the saw, but upon a very slight movement of the cut timber in engagement with the rear guard member, the lifting of the latter will throw the front guard member forwardly sufficiently to fall upon the work by gravity and consequently become immediately operative after the timber has s d rearwawllv beside the saw. or in case timber is withdrawn the front guard will fall to the table in initial operative position as before.

Various forms of quick-detachable mountug for the splitter upon the mounting member may be employed. In the present instance the member 12 is shown as formed with a planiform vertical face the lower end of the splitter being apertured to receive two rap screws 24: by which the splitter is securely clamped against the member 12. The guard parts may thus be permanently pivoted on the splitter with a good bearing, and they will automatically fall into proper operative positions with respect to the saw when the splitter is put in place.

I claim:

A rotary saw guard comprising a support adapted to be located over a rotary saw adjacent its vertical radius, a rear guard pivoted on the support adapted to lie beside a saw and in close relation to a work table for engagement by stock passing beside the saw, and a front guard pivoted on the support and separately movable from operative to inoperative position past dead center, the two guards being constructed to co-engage at the limit of raising movement of the front guard for support of the front guard in inoperative position while the rear guard is in initial position, said front guard being free to fall forward when the rear guard is raised pivotally a distance.

In testimony whereof I aflix my signature.

WILBUR s. NEIGHBOUR.
