The member 8 thus Other objects and advantages of the invention comprises the two supports II and I2 and the saving much time, which would otherwise be will in part be particularly pointed out in the spacing means I8. It will be seen that by this use on the circular saw tab1e in the bore ill to adjust the U-shaped member 15- construction the U-shaped member 3 may be swung in the bore I'I about the axis of its arm H, to bring the arm either above the table, as shown in Figs. 1, 2, 3, and 4, or into a position below the table, as shown in Fig. 5. The arm I! is also slidable axially in the bore |'I to permit lateral relative adjustment thereof, as desired, and in fact the same may be entirely removed by sliding it completely out of said bore II, when-- ever it is desired to do so.

The saw table may have the usual guide slots 9 therein for auxiliary appliances, which form no part of the present invention, such as miter gages or other sliding devices, and may be provided with the ripping fence ill with apertures 23 therein, which is slidable over the top surface of the table and securable by means of a nut 2d coacting with means l9, engaging the channel bar 22, fastened at the rear of the table by screws 2|, as best shown in Fig. and as claimed in the copending application, Serial No. 655,279.

The upper arm or support H of the U-shaped member 8 serves to provide a rod or pivot about which may be swung the member 30, which is pivoted about said arm ,H, as shown, and to which are secured the two arms 24, as by screws 25. The member '30 may be retained against shifting axially'on the arm H by means'of two collars 32 and 33, placed beyond the respective ends thereof, and retained adjustably in position by set screws 34 and 35, respectively. At

their outer ends the arms 2t accommodate a.

pivot-shaft or pin 26, secured at each end by a suitable cotter pin or the like 21, preventing the arms 24 from spreading outwardly. About this shaft 26 is pivoted a saw guard 28 commonly known as of the basket" type and having a sloping forward surface 3| adapted to be engaged and raised by a workpiece I36 when being fed to the saw, this being most clearly illustrated in Fig. 4.

This basket guard, when in the position shown in Fig. 4, completely protects the saw blade against accidental contact with the clothing or person of the operator, automatically rising when the workpiece I36 is fed to the saw, by

reason of the said sloping surface 3|, and againfalling back into place against the top of the saw table I when the workpiece I36 has passed beyond the rear end of the guard. This guard may be swung into several positions, as shown for example in Figs. 1, 2, 4, and 5, being in its inactive position in Figs. 1 and 5 and in its active position in Figs. 2 and 4. As clearly shown in Figs. 2 and 4 aslot 23 may be provided in the rear upper surface of the guard 23 for a purpose which will be explained hereinafter.

Referring now to Figs. 1 and 3, a guard of a different type is shown in position for use, namely, the splitter guard which is designated generally by reference character 43. This splitter guard consists primarily of a plate or blade of flat material, shaped as shown in Figs. 1, 2, 3 and 5,andasshownindetailinFig.6.

In Fig. 1 this guard is shown in place behind the saw blade 3 and substantially in the same plane as said saw blade so that a workpiece upon being ripped by the saw will pass partly on each side of the plate 40, with said plate engaging in the saw kerf. The forward edge portion of the plate lll is preferably bevelled, as shown at 43, the bevelled surface being formed as a curve corresponding to the size of the saw blade 3 so that when the saw blade 3 is advanced to its greatest extent above the top of the table, the

said bevelled edge will still clear the teeth of the saw by a suflicient margin of safety. The forward upper tip of the blade 40 is preferably rounded, as shown at 50, although the exact shape of said portion is not important.

The plate 40 preferably hasa flat lower edge as indicated at 41, which can rest firmly against the top of the table and in the rear of the said portion 41 a notch 48 may be provided, thereby keeping the top of said notched portion out of contact with the table so that any irregularities of the rear edge of said table will not affect the proper alinement and seating of the blade 40 upon the said table top. For a similar reason the downwardly depending portion 4| of the blade is so shaped that it remains out of contact with the table or the channel member 22 disposed at the rear thereof. Said depending portion 4| may be provided with an aperture 42, best shown in Fig. 6, which may be engaged over the lower arm or support i2 of the U-shaped memher ,8. It may be secured upon said arm or rod l2 between two collars 52 and 53, as shown in Fig. 5, said collars being secured to the rod or arm 82 preferably by a set screw 54 and a thumb screw 55, respectively, for simplicity of manipulation. A further coilar 51 may be provided on the rod or arm l2 and secured thereto by a set screw 58, said collar 51 preventing the arm or support l2 from passing axially outward from the-position shown in Fig. 5, for example, and thus assuring the proper positioning of the U- shaped member 8 and the guards carried thereby with respect to the saw blade 3. The rear edge I 46 of the plate or blade 4|! may be of any desired shape which does not interfere with the operation of the device, and is here 'shown as a circular arc, although it will be understood'that this configuration is chosen merely for simplicity and good appearance, and many other shapes will be equally satisfactory. A notched portion H, here shown as semi-circular in shape, (see Fig. 6), may be provided at the rear upper end of the plate and defined between the forward, somewhat blunt, point and the rear elongated projection or tongue 43. A depression or recess 5| is provided below the tongue 43 for a purpose which will now be set forth. 7

Referring to Fig. 1, it will be seen that the elongated curved tongue 43 enters between the rod II and the member 30 when the said member I 30 is swung into the position shown in said Fig. 1, or when in the position shown in Fig. 5. The provision of the depression 5| thus makes it possible to swing the basket guard 28 into the inactive position shown in Fig. 1 by providing room for the swinging of the member 30. It will be noted that the spacing between the aperture 42 and the notch 44 corresponds to the spacing of the supports or arms II and I2, so that the aperture and notch may simultaneously engage said two supports. In Figs. 2 and 4 there is shown a slot 29 in the guard 28, Fig. 2 showing how said slot 23 cooperates with the blade 40 to allow the guard 23 to fall into position over the saw blade 3 in spite of the presence of the blade 40.

It will be notedfrom Fig. 3 that, if desired, the upper rearward end of the plate 40 may be supported on the support or rod II by means of the two collars 36 and 31 located upon said rod on opposite sides of the notch portion 44 of the plate 43, said collars 36 and 31 being secured in their adjusted positions by means of the set screws 33 and 39, respectively.

Referring now to Fig. 7 it will be noted that said plate 40, in other respects, remainingidentical with that shown in Fig. 6.

The operation of the device will be obvious from the preceding description thereof, but may be briefly summarized'as follows:

If it be desired to employ the splitter guard alone, the machine maybe set up as shown in Fig. 1 or in Fig. 3, Fig. 1 showing the basket guard 28 merely thrown backward into inactive position where it does not interfere with the splitter guard blade 40 and Fig. 3 showing the basket guard removed entirely, together with its supporting means 30, 24, etc. Usually it will be preferable to employ the Fig. 1 set-up, because such set-up does not necessitate removing the basket guard and yet brings it out of the way of the operator so that the splitter guard 40 alone may be used.

Theoretically a series of splitter guards 40 may be provided, varying in thickness to agree with the widthof the saw kerf, or the thickness of the saw itself, measured across the set of the teeth, and in certain cases this may be desirable. However, in most cases a splitter guard of a single thickness may cooperate with saws of slightly different thicknesses, thus economizing in the expense and providing greater simplicity.

If, however, it is desired at any time to employ splitter guards of varying thicknesses, adjustment for this purpose is readily provided by means of the adjustable and removable collars '35, 3?, 52 and 53, whereby it is evident that the blade M may beaccommodated regardless of its thickness and may be adjusted into any desired position along the supports it and M. It will be noted that the splitter guard blade 40 has preferably a bevelled forward edge 49, which readily enters into the saw kerf in spite of slight inaccuracies of alinement between blade 40 and saw 3.

It is also clear that the blade 40 need not' be tightly clamped between the collars mentioned. but may be allowed a certain slight play so as to fioat" and accommodate itself readily to inaccuracies of alinement or inaccuracies in the saw kerf, thus preventing a tendency to bind,

which might otherwise occur if the splitter guard were held rigidly instead of being allowed to float.

The splitter guard may be readily placed in position for service by removing the outer collar 53 by means of the conveniently located thumb screw 55, thus giving free access to the end of the rod It, the said blade 40 being then engaged first with its notch 44 upon the rod l I and thenwith its aperture 42 upon the rod l2, whereupon the collar 53 is replaced and secured by means of the thumb screw 55. Inasmuch as the spacing between the arms or rods ii and I2 is substantially the same as the spacing between the aperture 42 and the notch 44 it is clear that this operation will lock the plate 40 securely upon the said two supports II and I2 and prevent any disengagement or loss thereof.

The same efiect will be secured if the Fig. '7 type of blade is employed, because the notch 58 will serve equally as well as the aperture 42 to retain the corresponding portion of the blade securely locked in place. The Fig. 7 form of blade is, therefore,'equivalent to the, Fig. 6 form inmost respects, but lacks the advantage that the Fig. 6 form may be permanently secured against loss on the rod I! by merely slipping the aperture 42 over said rod and then securing the plate by means of the collar 53 and thumb screw '55, allowing the blade to hang down freely from the rod I! when not in use, that is, without the notch simultaneously engaged upon the rod II. By so doing the blade 40 may be protected against loss or damage, while not interfering in any way with the operation of the saw.

If it be desired to employ the splitter guard in combination with the basket guard the parts may be arranged as shown in Fig. 2, whereupon the slot 29 in the basket guard will permit said basket guard 28 to move up and down with respect to the saw table, without in any way interfering with the operation of the splitter' used alone, the splitter guard 40 being either removed entirely from the machine or else swung into inactive position below the machine, as previously described.

Fig. 5 shows how it is possible to leave both the basket guard 28 and the splitter guard 40 permanently attached to the machine, and ready for use again instantly when desired, but yet swung entirely out of the way below the table top so as not to interfere in any way with certain operations of the/saw, such as grooving or dado work, for example, Where obviously a splitter guard cannot be used.

It is thus clear that there has been provided by the present invention a combination guard comprising a splitter type guard and a basket type guard, which, however, are not rigidly se-v cured to one another, but which are entirely independent of one another and which may be used either together or independently of one another and may even be swung in positions where they both' are entirely out of the way when it is desired to dispense with their use, and that the splitter guard provided by the present invention may be secured either relatively rigidly or in a floating manner, as desired, and may be held either only at its lower end or at both the top and bottom of the same, so as to adapt it to a vast variety of different conditions.

While a definite embodiment of such guards has been illustrated and described in detail in the present drawing and specifications, it is, of course, clear that many changes and modifications can be made in various features thereof.

without departing from the spirit of the invention.

Therefore, the scope of the invention is to be determined by the following claims and is not to be held to be limited to the exact forms illustrated and described herein.
