  1. 1
    I claim as my invention:1. In a device of the class described, a supporting frame having a top member and a bottom member, each of said members being provided with a circular opening, a saw A table rotatively mounted in the opening in the top member, a saw platform rotatively mounted in the opening of said bottom member, said saw table and said circular platform each being provided with an annular 75 rack, a pinion for each of said racks, a vertically arranged shaft for carrying and connecting both of said pinions to provide means whereby said saw table and said supporting table may be rotated in unison, and 80 means for imparting rotary movement to said vertical shaft.
  2. 2
    In a device of the class described, a supporting frame having horizontal top and bottom members, each of said members be- 85 ing provided with a circular opening, a saw table rotatively mounted in the opening of said top member, said saw. table being provided with, a saw slot, guide members carried by said top member, a circular platform so rotatively mounted in the opening of said bottom member, a saw frame pivotally mounted on said circular platform to swing in a vertical plane, a saw carried by the free end of said platform adapted to swing into 95 and out of position in the saw slot, of said saw table, each of said platforms being provided with an annular rack bar, a pinion for each of said rack bars, a vertical shaft for operatively connecting said pinions to 100 provide means whereby the said circular platform and said saw table may be rotated in unison so that the saw will, always be kept in alinement with the slot in said saw table and to provide means whereby the saw 10u may be rotated at various angles relative to said guides, and means for rotating said vertical shaft. ,, Des Moines, Iowa, December 0, 1922. LESTER T, FONDA. Secured to the back side of the frame member 411 have provided a spring 48, one end of which is connected to the circular platform 16 at 49. This spring tends to 6 normally hold the frame 39 in the position shown in clotted lines. At the forward end of the frame. 411 have provided a smaller spring 50 which is for the purpose of balancing the weight of the 10 frame 39. For positively limiting tne backward movement of the upper end of the frame 39 I have provided a link 39“ having one end pivoted at 39 b , and the opposite encl pro15 vided with a slot 39 c which is- designed to receive a pin 39 d secured in the irame member 40. The said link 39 a limits the movement of the frame backwards when the pin 39 a engages the upper end of the slot 39 c .. 20 Secured to the frame 39 I have provided an outwardly extending arm 51, the outer encl of which is provided with a hinge 53 to which a pedal portion 52 is secured. Tlie said hinge is so located that the pedal 525 may be swung upwardly and inwardly to such position that when the frame 39 is rotated, as hereinafter to be described, the pedal will not engage the posts 10. Secured to the top of the table 11 I have 80 provided the usual guide plates 54 which are adjustably mounted by means of thumb screws 55. . -,-.-4-11 By the arrangement just described, it will be seen that the plate 30 and the circular 35 platform 16 are both rotatively mounted and are designed to operate in unison by being connected to the pinion gears 23 and 2r onthe shaft 20. Thus it will be seen that the operator 40 may grasp the handle 27 and rotate the shart • 26, and that the plate 30 and the platform 16 will be rotated in unison. This will cause the frame 39 to also be rotated so that the saw 43 is always in alinement with the slot 45 111'40 By this arrangement the saw blade 43 may be brought into position parallel with the face of the guide plates 54 or transversely therewith, and at any immediate angles be60 tween the two positions so that the saw may be used either as a cross cutting or a ripping saw, and whenever desired, as a miter saw. . The saw is brought into operative position by the operator placing his foot on the 55 pedal '52 which will swing the upper end of
