LOUIS PHILLIPPS, OF COLUMBUS, NEBRASKA.,

DRAGMSAW.

SPECIFICATION forming part of Letters Patent No.. 622,709, dated April 11, 1899, Application filed October 8,1898. Serial No. 693,059. (No model.)

To @ZZ whom t may concern:

Be it known that I, Louis PHILLIPPS, a citizen of the United States, residing at Columbus, in the county of Platte and State of Nebraska, have invented a new and useful Drag- Saw, of which the following is a specification.

This 'invention relates generally to saws, and more particularly to a dragsaw and means for operating the same, the objects of the invention being tov provide a cheap and simple means for operating the saw, holding the same down when in operation, together with means for holding the log and adjusting the saw-operating mechanism.

With these objects in view the invention consists in the peculiar construction of the various parts and their novel arrangement and combination, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this specification, Figure l is a vieuT showing the practical application of kmy invention, and Fig. 2 is a section taken through one of the stand# arde.

In carrying out my invention I employ a base A, upon which are mountedtwo upright standards B, connectedat the top bya cross-beam O. The standards are braced in any suitable manner and are slotted vertically, as shown at B', to receive the guide-bolts D of the bearing-blocks D, said guide-bolts passing through the slots in the standards and carrying the washer and nuts upon the rear ends. The bearing-blocks are connected by a cross rod or bar E, which in turn is connected with a threaded rod F, passing up through the top cross-beam and working in a nut F', said nut having a hand\vheel F2 and ratchetwheel F3 connected therewith, and a pawl F4 is pivoted on top of the beam and engages the ratchet-wheel to hold the nut in a locked position, and by turning the hand-wheel the nut is turned and the rod is raised or lowered, and consequently the bearing-blocks. These bearing-blocks are preferably made of channel-iron, and a crank-shaft G is journaled in said blocks near their lower ends, said crankshaft being connected with the saw-pitman H by means of a stirrup H', said pitman being connected with the saw H2 in any suitable slotted obliquely, so that the shafts can be readily removed whenever desired'. A beam K is pivoted to one of the bearing-blocks and `extends parallel with the pitman and saw, said beam having a clampdever K' pivotedV adjacent to the forward end, said clamp-lever being intended to bear upon the log and hold it steady while the machine is in operation. A toothed segment K2 is carried upon the beam K, and the clamp-lever is provided with a thumb-latch lever K3 for engagement with the-said segment and b'y means of which the clamp is held securely fixed. A presser-rod L is attached to the beam K and projects forwardly and laterally, so that its end rests above the saw, and an antifriction-roller L' is mounted in said end and bears upon the top of the saw, thereby holding said saw down, pressure being supplied by a spring L2, fastened to the beam and bearing upon the rod L; By means of the hand-wheel and nut the saw-operating mechanism can be raised or lowered, as needed7 and whenever it is desired to saw a standing tree the mechanism is laid upon its side, the small gear removed from the crank-shaft and the crank-gear substituted, and the iiy-wheel is placed upon the shaft I.

A sawing mechanism constructed as described is both cheap and simple in construction, easy to operate, and can be shifted or changed tomeet all circumstances.

Having thus fully described my invention, what l claim as' new, and desire to secure vby Letters Patent of the United States, isv` l, In a drag-saw mechanism, the combination with the base, standards and cross-beam, said standards being slotted, of the bearingblocks, one of which is slotted obliquely, the crank-shaft, drive-shaft and gears and` fly wheel, the saw and pitnian, the beam and clamp-lever attached thereto, the presser-rod and spring, the bar connecting the bearingbloclrs, the screw swiveled thereto, the hand IOC) Wheel nut and ratchet and 'paW], al1 arranged and adapted to operate substantially as shown and described.

2. In a drag-saw mechanism, the combination with the base, standards and cross-beam, said standards being slotted, of the bearingblocks one of which is slotted obliquely, the crank-shaft, drive-shaft and gears, and Iiy- Wheel, the bar connecting the bearing-blocks',

4the screw swiveled thereto, and the hand- 1o Wheel, nut and paWl and ratchet, all substantially as described.
