SAWING ATTACHMENT FOB TRACTORS.

Application filed September 2a, 1923. Serial mi. 665,721.

This invention. relates to sawing attachments for tractors and has for its object the provision of a simple and comparatively inexpensive saw table. which can be fastened to and carried by a common and popular form of gasoline tractor and operated therefrom, by means of which a. carpenter or other contractor can increase the speed and decrease the labor of erecting frame buildings, concrete forms, stagings, bridges, etc. To accomplish this it is necessary to have a saw table which will handle long and wide boards, and receive them lengthwise as well as sidewise; which will cut with accuracy in all directions, which can be applied, removed with ease, and transported without removal; and itis desirable that the device be so constructed as to enable the tractor to be used for its original purpose without removing the sawing attachments. All these things are accomplished-by my invention, while further objects and advantages will become apparent as the description proceeds.

In the drawing accompanying andforming a part of this application, I have shown one physical structure in which my inventive ideas can be embodied though without intent to limit myself to the particular forms or arrangements herein shown. Fig. 1 is a perspective view of-a simple form of tractor equipped with my device and in traveling condition; Fig. 2 is a side elevation of my device and a part of the tractor; Fig.

. 3 is a top plan view'with part of the table broken away; and-Fig. 4 is. a front elevation I of the saw table omitting the tractor.

Describing the parts herein shown bythe use of characters .of reference appearing on the drawing, the tractor is e uipped with a radiator. 1, tank 2, engine 3, ront wheels 4, and driving wheels 5. Theengine is located in a fore and aft position behind the radiator and has a crank case 6 flanged at 7 and bolted to a similar flange 8 carried by the gearcase 9. Gears of some kind being common in all tractors I do not Show the same, but a transverse work-shaft is journaled in this gear box and provided wlth a belt ulley 10 and suitable clutches are provided power of the engine can be delivered either to the drive wheels 5 or to the pulley 10 at will.

To the sides of the tractor I secure two (not shown herein) whereby the.

thereon supporting the arbor 19 having at' one end the circular saw 20 and at the'other end the pulley 21 connected to the workpulley 10 by the belt '22. Thrust bolts 23 are interposed between the bars 15 and 17 to tighten the belt, and a clamping bar 24 beneath the sills is connected to the bar 17 by bolts 25, 25, to enable the latter bar to be secured in place. Thus far the device isiclentical with that described and claimed in the applications of O. W. Johnson,.filed April 28, 1921 and March 16, 1922 Serial Nos. 465,342 and 544,222.

To the bar 17 I attach bolsters 30, 30 which project forward parallel to the sills 12, and in case I distrust the width and strength of the cross bar 17 I introduce another cross bar 31 between the bolsters and sills, together with acompanion clamping bar 32 and clamping bolts 33. To the upper edges of the bolsters I fasten the cleats 35, 35 which in turn support the saw table 36. This table is formed with a slot'for the saw 20 and is also, made somewhat in the shape of the letter L, one portion projecting laterall in front of the radiator and the other ortlon 37 lengthwise past the radiator.

he arbor 19 is located as near the radiator as is safe .in view of the prevailing width of boards to be cut, sap feet, and the saw is disp aoed laterall from the radiator enough to enable satis actory from one to two' ri saw service. Therear end'37 of the saw ta 1c is elevated sufiicie'ntly to direct all pieces of lumber over the rear wheel of the tractor and supported by suitable brackets 38, 38.- These are preferably rigid with the sill 12 and attached to the saw table by a. slot connection 39, 39.

v Formed in the top of the table are suitable be done I may employ the temporary supports shown in Figs. 2 and 4. These consist of iron rods 45, bolted to some part of the table and connected to iron feet 6, 46 by turnbuckles 47, 47. These can readily be accommodated to rough ground, which is the kind generally found where building operations are going on, but are seldom necessary except for fine work.

The tractor can be driven about with the same facility with the saw table as without. It can draw a load of lumber to the job or about a job, sawing it wherever most convenient. The saw table being rigid with the shaft support, the guides are always accurate relative to the saw. To tighten the belt the bolts 25, 33, and 39 are loosened, the bolts 23 advanced, and the bolts 25, 33 and 39 tightened again. The entire device can be removed from the tractor at any time by loosening the bolt 14 and unfastening the brackets 13, 13 and reattached by reversing the process.

I have designed and described device of minimum complexity and maximum utility. It will be obvious that additional features may be incorporated or advantages omitted without departing from my inventive idea or avoiding a proper construction of these my Letters Patent, and I do not limit myself to any of the features herein illustrated and particularly described but only as specifically recited in my several claims with benefit of equivalents in accordance with the state of the art.

Having thus described my invention what I claim is:

1. The combination with a tractor having wheels of unequal size, of a detachable 2. The combination with a tractor, of a frame supported at one end thereof and extending beyond the same, a transverse arbor journaled thereto, means for driving said arbor from the tractor, a saw on said arbor located outside the body of the tractor, and an L shaped saw table carried by said frame and overlapping the end-and side of said tractor.

3. The combination with a tractor having smaller front wheels than rear wheels, of a frame carried by said tractor and extending in front of the same, a transverse arbor journaled thereto, means for driving said arbor from the tractor, a saw on said arbor outside the body of the tractor, and an L shaped saw table carried by said frame and overlappin the front and side of the tractor, said ta 1e bein located above the front wheels and incline to bring its plane above the rear wheel.

4. In a tractor attachment, the combination with a frame adapted to be secured to the tractor body of a cross piece movable relatively to said frame, a transverse arbor journaled to said cross piece,- means for driving said arbor from t e tractor engine, a saw on said arbor, and a saw table ri 'd with said cross piece and movable therewith.

In testimony whereof, I hereunto afiix my signature.
