Be it known that I, VALTER H. SEAVEY,

a citizen of' the Unitedls'tat'es, residing at Kearsarge, in tliecounty of Garroll and- State of New Hampshire, have invented new and'useful Improvements in Saw 2 of which the following is a specification.

This invention relates to saw rigs and has for an objectthe provision of a rig which is simple inconstruction, easy to op-' crate and may be readily transported from place to place, the invention being especially adapted fbr sawing cord wood.

Another object of the invention is the provision ofnovel means for feeding the wood'to the saw, whereby'operation of the latter will exert a'downward pressure uponthe' wood and greatly facilitatethe operation of"sawing,-so that a given amountof material may be sawedi'n' a relatively short time and with a-mi'nimum'amount of labor.

Another. object of] the invention is the provision of novel" means for adjusting the level of the feeding table so that the latter may be properly adjusted for use even though the rig is out of level.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a side elevation of a saw rig constructed in accordance with the invention.

Figure 2 is a'front view of the same.

Figure 3 is a top plan view.

Figure 4 is a longitudinal sectional view.

Referring in detail to the drawings wherein like characters of reference denote corresponding parts, the rig is shown as comprising a supporting frame, the latter including spaced sills or runners 10 from which rise standards 11. These standards are connected by longitudinal timbers 12 and transverse connecting bars 13. A rigid frame is thus provided which may be supported in any manner such as wheels or runners, the sills 10 serving as the latter. If desired the frame may be supported upon a bench or table, according to the character of the work for which it is intended.

Mounted in bearings 14 supportedupon the sills 10 is a shaft 15 and secured upon this I shaft is-asaw blade 17 Also secured upon the shaft 15 is apulley 18 which is-driven .by a belt 19-an'dth'e latter may'befoperated fromany suitable source of. power such as a motor orjengine, 'either mounted-Rupert the supportingfranie or mounted separately therefrom. The belt is preferably pro vided with an automatic tightener shown in the form ofa= roller. 20 whichengages the belt, and which is carried at oneend of an arm21-=,:the opposite endz. of which is pivot.-

ally mounted upon the frame asshown, at

Supported by the frame just describe'd' is: a feeding frame, the latter" inclilding spaced' parallel substantiallyhorizontallydisposed"- beams 23 to thenfrontiends-off whichis s.ecured atable 24 uponwhich the inate ria'lzis placed to be fed to thesaw'; This tableiis transversely slitted' as shown at 25 to. receive; the saw and i carries a" guard: 26' forfthe: protect'io'n of tlieoperator Bivot'ally secured adi ac-ent the: front ends-of. thesbeams 23; are the lower ends of hanger bars 27 The upper ends of these bars are pivotally secured to the timbers 12 throughthe medium of a rod 28, the outer ends of which extend through slots; 29 provided in the timbers 12. The point of connection between the hanger bar 27 andthe timbers 12 may thus be regulated by moving the rod 28 in the slots 29. The rear ends of the beams 23 have pivotally secured thereto the lower ends of rear hanger bars 30, the upper ends of which are pivotally secured to the timbers 12 as shown at 31. The points of connection of the upper ends of the bar 30 are in advance of the points of connection of the lower ends of these bars so that the tendency of the feeding frame just described will be to move the table 24 away from the saw blade 17.

The position of the table 24 with relation to the blade 17 is such that when work upon the table is fed toward the saw the latter will engage the work in such position as to exert a downward pressure so that there will be no tendency of thework to raise from the table. The-operation of sawing will thus be materially assisted.

Mounted in bearings 32 provided in the bars 13 is a longitudinally disposed threaded rod 33. Mounted upon and threadedly engaging this rod is a nut 34. Rods 35 have one of their ends secured to the nut 34 while the opposite ends of these rods are secured to the front hanger bars 27 as indicated at 36, so that by rotating the threaded rod '33 the nut will be moved longitudinally of the rod and will carry with it the upper ends of the hanger bars 27 so as to regulate the pivotal positions of these rods. The threaded rod 33 is preferably provided with an operating handle 37.

By changing the pivotal points of the upper end of the hanger bars 27 the position of the table 24 may be regulated so that the e said table may be leveled even though the supporting frame is out of level.

The invention 1s susceptible of various changes 1n 1ts form, proportions and minor details of construction and the right is here-.

in reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is g I I 1. A. saw rig comprising a supporting frame, a saw blade mounted for rotation thereon, means whereby the blade may be driven, a feeding frame comprising spaced substantially horizontally disposed beams, a feeding tablesecured to the front ends of the beams and normally spaced from the saw, front hanger bars having their lower ends pivotally secured to the beams and their upper ends pivotally supported in the supporting frame, rear hanger bars having their lower ends pivotally secured to the lower ends of the beams and their upper ends pivotally secured to the supporting frame in advance of the pivotal connections of their lower ends, whereby the table will normally swing in a direction away from the saw and means for regulating the point of connection of the front hanger bars and the supporting frame.

2. A saw rig comprising a supporting frame, a saw blade mounted for rotation thereon, means whereby the blade may be driven, a feeding frame comprising spaced substantially horizontally disposed beams, a feeding table secured to the front ends of the beams and normally spaced from the saw, front hanger bars having their lower ends pivotally secured to the beams, a slidable pivotal connection between the upper ends of said bars and the supporting frame, rear hanger bars having their lower ends pivotally secured to the rear ends of the beams and their upper ends pivotally secured to the supporting frame in. advance of the pivotal connections of their lower ends, whereby the table will normally swing in a direction away from the saw, a threaded rod extending longitudinally of and mounted in bearings carried by the supporting frame, a nut mounted upon the rod and rigid means connecting the nut and front hanger bars,
