The supporting coh'nini 'or standard 1 35 carriesa suitable table 2 which, for the sake of promotingclearness and simplicity in the E drawings, is shown stripped of all, the usual attach1nent's,sueh as the work-holding lever, the gages, the sliding table, line-holders,

The pulley S) being rigidly secured to. the

shaft 4,,it will be seen that the rotation of the latter. is conmimncated to the saw.

I come now to the triminer-arrangement:

.Mounted loosely upon the shaft is a sleeve or hub 13, provided on one sidewith' a hen dle l-l, and on the other side with anal-1n or extension 15,- The outer extremity of tlns arm carries a sleeve 16, in which is snugly ournaled a shaft l7. It is to this shaft that the trin-i-mer 18 is secnredj' This trimmer may be of, anyimprove'd construction,in

the particular instance illustrated, it consists of a solid lmdy-portion having a sufii- (-ient number of openings 19 therein (the trimmer shown in F 3 has three openings). In each of these openingsis adjustably secured (as by screw 19) a trimmer-knife 20, having a cutting edge 21'. The pulley rigidly fastened to the'projet-ting end of shaft; 17, is connected by a belt 23 to the pulley 2t seeuredto the shaft; 4 between the hub 13 and the inner bearing 3. It will be observed that inview ofthe loose mounting of the hub 13 on the shaft 4, the trimmer-mechanism will normally assume a vertical position due to gravity, as indicated in dotted lines in Fig. 1. In thig way the trimmer normally in an idle or inoperative position, without leastwise interfering-with the proper working of the saw. In case it is desired to use the trimmer,

I it is simply necessary to grasp the handle 14-.

passed beyond reach of the saw (as .indicated at 24' in Fig. 2), it enters the field of action of the trimmer-knives, which trim it down to the required size or form. Upon releasing the handle-14, the entire trimmer-' arrangement drops out of the way, readyto If desired, suitable stops be moved into operative position at any mo- -ment.

' Although I have shown and described one embodiment of my invention, yet I- will have the essence of my invention, as set forth in the annexed claims, is susceptible of other and further embodiments or modifications -which might suggest-themselves to those skilled in thear and which, therefore, the' appended claims seek to cover;

and a trimmer head carried by said standard rotating in theisamc direction as the sawand in a plane parallel therewith, trimmers mounted in said head-projecting-beyond the face of the head and into the line of travel of the material whereby the cut made by the saw will be trimmed by said trimmers, the relation of the head to the saw being such;- that the work must be fed to the trimmers in the same direction as itis fed to 'the saw, said trimmer head being mounted to move'independently of the table substantially vertically into and out of the plane ;of the table through an opening 2. In a device of the character described, the-combination with a standard, of a fiattopped work supporting table having an opening therein mounted on said standard,

said standard arranged to the rear of said saw rotating in the same direction as .the saw and m a plane parallel with the saw,

trimmers mounted insaid'hcad' projecting beyond the faceof .theliead and into the line of travel of the' material whereby the cut made by the saw will betrimmed by 'said trimmers, said trimmer head being molinted to'moveindependently of the table substantially vertically into and out of the plane of the table through an opening.
