NUT-CRACKING MACHINE,

Specification of Letters Patent.

Patented May 30, 1916.

Application filed March 30, 1915. Serial No. 18,059.

To all whom it may concern Be it known that I, WILLIAM A. COULSON, a citizen of the United States, residing at Moss Point, in the county of Jackson and State of Mississippi, have invented a new and useful N ut-Gracking Machine, of Which the following is a specification.

This invention relates to a machine for cracking nuts, and comprisesa reciprocating hammer, an adjustable anvil, and means for bringing the nuts into position between the hammer and anvil, and for removing them from position after being struck by said hammer.

The invention consists in the novel fea tures of construction hereinafter described, pointed out 'in the claims and shown in the accompanying drawings in which,

Figure 1 is a plan view. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is an inverted plan view. Fig. 4 is a section on the line 4-4 of Fig. 1. Fig. 5 is a section on the line 5-5 of Fig. 1.

In these drawings 1 represents a suitable table having a longitudinal slot 2 and end extensions 3. A shaft 4 is journaled in the extensions 3, and carries an eccentric 5 provided with an eccentric strap 6, and rod 7 to which is pivotally connected a plunger 8 having a hammer head 9 the free end of which is suitably shaped to engage a nut.

As most clearly shown in Fig. 5 the plunger 8 slides in thesuitable guideways 10.

Upon opposite sides of the table are mounted spur wheels 11 over which runs an endless belt 12, and said belt carries suitable nut holding devices 13. An anvil 14 is carried by the table 1, and said anvil is formed in two sections a movable section 15 being supported from the fixed anvil. 14 and adjusted by means of threaded rods 16, the movable section or face having a recess 17 serving to hold and center the nut when struck by the hammer.

On the other side of the table is journaled a shaft 18 upon which one of the spur wheels 11 is fixed, and said shaft carries a beveled gear 18 which meshes with a beveled gear 19 carried by shaft 20, which shaft extends across the slot 2. The shaft has fixed upon it a ratchet wheel 21 and mounted loosely upon the shaft is a mutilated gear wheel 22 which meshes with a rack 23 carried by the underside of the plunger 8 and working in the slot 2.

A spring pressed pawl 24 engages the a reciprocating motion to the plunger 8, and

as this goes forward itwill strike a nut carried by the belt 12 and in alinement with the hammer and the recess 17 of the movable face 15 of the anvil 14. The face 15 can be adjusted by means of a rod 16 to nuts of various lengths. During the forward move ment of the plunger the gear 22 is rotated in such direction that the pawl 24 slips on the ratchet wheel.

Upon rear movement of the plunger the gear22 is rotated in the opposite direction and the pawl rotates the ratchet 21, shaft 20, gears 19 and 18 and shaft 18 causing the belt 12 to travel just a sufficient distance to bring another nut in position to be struck upon the next forward movement of plunger. When the nuts after being cracked reach the side of the tableand in position to be carried downwardly over one ofthe spur wheels they will fall from the belt into any suitable receptacle.

The shaft 4 can be turned by an desired means and I have shown a pulley 2 on said shaft which may be driven by a belt from any suitable motor, not shown.

The advantages of the device and its operation and construction will be clear from the drawing and the description, and I do not wish to be limited to any particular form of motive power, or to any special construction of nut holding devices, or any special construction of belt.

What I claim is:

1. In a nut cracking machine, the combination with an intermittently movablecarrier belt and a reciprocating plunger, of a rack bar carried by the underside of said plunger, a shaft at right angles to the plunger a mutilated gear on said shaft adapted to be engaged by said rack bar, said gear being loose on the shaft, a ratchet fixed to the shaft, a pawl carried by the gear and adapted to engage and actuate said ratchet on reverse movement of the plunger, and means for communicating said movement to said carrier belt.-

2. A device of the kind described, comprising an anvil, a reciprocating plunger the free end of the plunger forming a hammer head, an endless belt adapted to travel between the hammer head and anvil, a shaft for driving said belt, a second shaft arranged at right angles to the plunger, means carried in part by said plunger and by said second shaft for rotating the second shaft, during rearward movement of the plunger, and means for transmitting rotation of the second mentioned shaft to the wheels, nut holding means carried by the belt, a shaft arranged below the table and across said slot, a gear wheel loosely mounted on said shaft and in alinement with the slot, a rack bar carried by the plunger and engaging said gear wheel, a ratchet fixed on the shaft, a pawl carried by the gear wheel adapted to rotate said ratchet upon rearward movement of the plunger, and means for transmitting intermittent rotation of the said shaft to one of said spur Wheels.

WILLIAM ATKINSON COULSON.
