PATENT FF IQE LESTER T. FONDA, OF AIVEES, IOWA.

sAw Ne MACHINE.

Applicationfiled December 11, .1922. serial No. 6065166.

The object of my invention is to provide an improved saw mechanism of simple, durable and inexpensive construction .so or ranged and constructed that it adapted to perform :1 number of different lcmdsot sow work.

More specifically it is the object of my invention to provide a saw mechanism capable of being easily and quickly-adapted to various kinds of saw work, such as cross cut ting, ripping and mitering.

These and other objects will be apparent to those skilled in the art.

lh'ly invention consists in the construction, arrangement and combination of the various parts of the device, whereby theobjectscontemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

.l igure 1 is a plan view of my improved saw.

l igure 2 is a sectional view taken on the line 22 of Figure 1.

Figure 3 a transverse, sectional view taken on the line 33 of Figure 2.

My improved device comprises a frame having legs 10 and a table 11 on the top end of said legs. Near the lower'end of the legs 10 l have provided a platform 12 which is provided with a comparatively .large cii culztr opening 13. The said platformhas in its upper face near the edge of the opening 13, a ball race 14 designed to carry a number of ball be: sings 15.

Mounted on the balls 15 I have provided a circular platform 16 which is providedwith a downwardly extending portion 17 de signed to enter the opening 13, and a flanged portion 18 designed to rest onthe balls 15. The circumferential.edge of the flange 18 is provided with a series of teeth 19.

Arranged vertically in one side of the frame I have provided a shaft 20, the lower end of which is provided with a pinion 21 designed to mesh with the teeth 19 of the platform 16. The upper end of the shaft 20 is mounted in the table 11. The said table is provided with a recess 22 to receive a gear 23 on the upper end of the shaft 20. The shaft '20 is also provided with a beveled gear 24 in mesh with the beveled pinion 25, said pinion being mounted on a horizontally or 'a-nged shaft 26, the outer end of which is provided with a hand wheel 27. The shaft 26 .is llllOlllltECl in a bearing 28 secured to the lower face of the table 11. The table 11 isprovided with a circular opening 28 into which extends the circular flange 29. Said opening 28 being arranged vertically above theopening 13.

Rotativoly and slidebly mounted on the flange 29 I have provided a circular plate 30 which is preferably formed of comparatively soft metal such as aluminum whilethe'table 11 maybe formed of. cast iron or steel. The plate 30 is provided through its central portion with a slot 31 in which is mounted a wooden frame. 32. The saidfrsme 32 is provided witha slot 33 which is for the purpose of receiving the saw hereinafter to be men tioned.

The circumferential edge of the plateBOis formed with a groove 34 which is designed toreceivc a numbercf pins 35 for the pur pose of retaining the platewithin the opening 28. These pins are inserted in the side of the table 11 insuch a manner that they may be removed-at anytime desired.

The circularedge of the plate 30 is also provided with a seriesv of teeth 36 designed to mesh withthe gear 23.

Secured to the central. portion ofthe circular platform .16 arebearing supports 37 in whichis mounted a shaft 38. The said shaft 38 has secured to it a frame 39 which is provided withuprights 40, the upper end of said uprights being provided withsupporting members 41, said members having mounted thereon a shaft 42 by means of suitable bearings.

'lheshaft 42 is provided to carry a circularsaw 43 and abelt wheel 44. The saw 43 isso locatedthat it will operate in the slot of the plateBO. The frame 39being pivotally mounted is free to swing in such a manner-thatthe saw 43 may be moved from one end of the slot/33 to the opposite end, and also so arranged that the saw will disappear below the surface of the plate 30 when in one position of its movement, as shown in dotted lines.

The frame 39 has mounted on it a motor 45 carrying a belt wheel 46 which is in alinement with the belt wheel 44, the last two wheels being designed to carry a belt 47.

By this arrangement it will be seen that I have provided means whereby the saw 43 may be constantly driven regardless of whatever position the same may be, in.

Secured to the back side'of the frame member ll 1 have provided a spring 48, one end of which is connected to the circular platform 16 at 49. This spring tends to normally hold the frame 39 in the position shown in dotted lines.

At the forward end of the frame ll I have provided a smaller spring 50 which is for the purpose of balancing the weight of the frame 39.

For positively limiting the backward movement of the upper end of the frame 39 I have provided a link 39 having one end pivoted at 39 and the opposite end provided with a slot 39 which isdesigned to receive a pin 89 secured in the frame member %0. The said link 89 limits the movement of the frame backwards when the pin 39 engages the upper end of the slot 89 Secured to the frame 89 l have provided an outwardly extending arm 51, the outer end of which is provided with a hinge 53 to which a pedal portion 52 is secured. The said hinge is so located that the pedal 52 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 provided the usual guide plates 5% which are adjustably mounted by means of thumb screws 55.

By the arrangement just described, it will be seen that the plate 30 and the circular platform 16 are both rotatively mounted and are designed to operate in unison by being connected to the pinion gears 23 and 21 on the shaft 20.

Thus it will be seen that the operator may grasp the handle 27 and rotate the shaft 26, and that the plate 30 and the platform 16 will be rotated in unison. the frame 39 to also be rotated so that the saw 13 is always in alinement with the slot 33.

By this arrangement the be brought into position face of the guide plates 5% or transversely therewith, and at any immediate angles between the two positions so that the saw may be used either 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 pedal 52 which will swing the upper end of saw blade d3 may This will cause parallel with the the frame upwardly, carrying with it the saw 43. The circular plate 16 may be formed of comparatively heavy material so as to reduce the vibration of the saw as it is being operated.

Thus it will be seen that I have provided a universal saw mechanism of simple, durable and inexpensive construction, which is adapted to perform a large variety of operations.

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 table rotatively mounted in the opening in the top member, a saw platform rotatively mounted in the opening of said bottom memher, said saw table and said circular platform each being provided with an annular rack, a pinion for each of said rac (S, a ver tically 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 means for imparting rotary movement to said vertical shaft.

2. In a device of the class described, a supporting frame having horizontal top and bottom members, each of said membersbeing 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 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 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 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 may be rotated at various angles relative to said guides, and means for rotating said vertical shaft.
