WEDGE-CUTTER.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed January 21, 1908. Serial No. 412.003.

To all whom tt may concern:

Be it known that I, LEWIS W. ROULAND, a citizen of the United States, :residing at Olivet, in the county of Osage and State of Kansas, have invented new and useful Improvements in. Wedge-Cutters, of which the following is a specification.

The invention relates to an improvement in wedge making machines, comprehending specifically a structure adapted for the convenient formation of wooden wedges in a simple and ex editious manner.

The main o ect of the present invention is the provision of a wedge making machine including a base and a knife arranged to cooperate with the base, the base being adapted to support the block from which the wedge is cut and being rendered adjustable so as to permit the operator to vary the sizes of the wedges, as described.

The invention will be described in the following specification, reference being had particularly to the accompanying drawings, in which z- Figure 1 is a view in side elevation illustrating my improved wedge making machine. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a view similar to Fig. 1 with the adjustable base in lowered position. Fig. 4 is a plan of the wedge making machine. Fig. 5 is an enlarged section on line 5-5 of Fig. 3. Fig. 6 is an enlarged section on line 6 6 of Fig. 3.

Referring particularly to the drawings, my improved wedge making machine comprises a bed 1, preferably in the form of a rectangular block of materially greater length than width, said block being of a size to render the machine stable in operation or may be so formed as to permit the attachment of the machine to a suitable fixture, as awork bench or the like.

Secured on the base at a point intermediate its ends is a guide block 2, which is coextensive in width with the width of the bed and is formed in its relatively upper surface with a longitudinally disposed channel 3. A knife or cutter 4 is mounted for longitudinal movement in the channel 3, being secured therein against other than longitudinal movement by a plate 5 overlying the knife and upper surface of the block, said plate being secured in place through the medium of screw bolts 6, which extend through the block and take into the bed, thereby serving to also secure the block to the bed. The rear or inoperative end of the cutter 4 is connected through the medium of a link 7, with a lever 8 pii otally secured at 9 to the rear end of the bed, the operation of said lever serving to reciprocate the cutter in the chain nel 3 in an obvious manner. The connection of the link 7 with the lever 8 is rendered adjustable through the medium of a series of perforations 1 0 for the connecting bolt, wherey the extent of throwof the cutter may be varied at will.

Beyond the forward end of the guide block 2 and below the operative end of the cutter 4 is arranged what I term the block holder 11, comprising a block of somewhat less width than the width of the bed 1 and formed in its upper surface in that portion underlying the cutter 4 with a depression4 including an abrupt shoulder 12 and an inclined base 13, the shoulder being disposed at right angles to the normal surface of the holder and the base 13 inclining from said shoulder downwardly and forwardly toward the guide block 2. Right angled bracket plates 14 are secured upon the bed 1, their shorter arms extending vertically above the bed on o posite sides of the holder 11, the free ends o* the projecting portions of the brackets being slotted at 15 to receive a bolt 16 passed through the holder, the threaded terminal of the bolt being provided with a nut 16 beyond one of the brackets. By this construction the relatively forward portion of the holder is arranged for vertical adjustment within limits while otherwise maintained in the saine relative position to the bed 1.

Centrally of the rear portion of the holder 11, or of the depression formed in said rear portion, the base 1 is provided with an adjusting bolt 17 having a head 18 to bear against the lower surface of the holder 11, the body of the bolt having threaded enga ement with a socket member 19 seated in t e bed 1, the lower terminal of the bolt being formed with a kerf, as shown, to permit the necessar operation of the bolt.

The blade 4 rearwardly beyond the guide block 2 is provided with an adjustable stop 20, com rising plates designed respectively to under ie and overlie the cutter and to be connected by bolts 21, whereby they may be clamped in fixed relation to the cutter at will.

By this arrangement the projection of the cutter through the guide block 2 may be limited as'desired through the medium of a stop 20, so that the cutting depth of the blade may be gaged in accordance with the wedge to be formed.

From the above description it will be noted that the cutter moves in a plane parallel to the plane of the bed 1, and that the base 13 of the block receiving depression in the holder is at an incline to the path of movement of the cutter. It is, therefore, obvious that if a block of material is seated in the depressions, with one edge resting against the shoulder 12 and its lower surface resting against the inclined base 13 of the depression, operation of the lever 8 will project the cutter through the block of material and form the wedge. The size of the wedge may be readily regulated by adjusting the screw bolt 17, and also the forward end of the holder through the bolt 16, which varies the angular relation of the base 13 of the holder 11 with relation to the plane oiE operation oi the blade and thereby causes variation in the size of the wedge cut in the movement of the blade, the cutting end of the blade, however, always meeting the shoulder 12, as will be evident from Figs. 1, 2, and 3 of the drawings. This adjustment is effectual in adapting the machine to cut wedges of any size within the capacity of the machine.

Having thus described the invention what is claimed as new, is

1. A wedge making machine comprising a bed, a guide block secured thereon and formed with a longitudinal channel, a cutter mounted for reciprocatory movement in the lannel, means for operating the cutter, bracket lates secured to the bed in s aced relation beyond the guide block, a blocli carrier pivotally mounted in said plates and formed with a block receiving depression, and means for adjusting one end of the carrier, said means underlying the block receiving depression.

2. A wedge making machine comprising a bed, a guide block secured thereon, a cutter mounted for movement in the guide block, means for o erating the cutter, bracket plates secure( to the bed in spaced relation beyond the guide block, a block carrier pivotally mounted in said plates and Jformed with a block receiving depression, and a bolt threaded through the bed and engaging the carrier beneath the block receiving depression, whereby said carrier may be adjusted by operating the bolt.

In testimony whereof I affix my signature in presence of two witnesses.
