Title: Rifle pellet casting mold

Description:
I have invented a new and novel rifle pellet casting mold. My rifle pellet casting mold can be used to provide various styles of pellets and uses pouring sprews and gates to regulate the flow of the pellet material into the molds as well as pins to insure rigid assembly of the mold before casting begins. 
    
    
     My invention can be understood in view of the accompanying figures. 
     FIG. 1 is a cross sectional view of a group of different types of pellets which may be cast by the mold. 
     FIG. 2 is a perspective view of the mold in use. 
     FIG. 3 is a view of the mold opened for removal of the cast pellets. 
     FIG. 4 is a view of the mold taken along the plane 4--4 of FIG. 2. 
     FIG. 5 is a cross sectional view of the mold taken along the plane 5--5 of FIG. 2. 
     FIG. 6 is a cross sectional view of the mold taken along the plane 6--6 of FIG. 2. 
    
    
     With regard to FIG. 1, a variety of types of rifle pellets may be cast in the mold of this disclosure including a round headed pellet 10 a pointed pellet 12 a flat faced pellet 14 and a rifle type pellet 16 depending upon the construction of each of the individual mold chambers. 
     With regard to FIGS. 2, 3, 4, 5, and 6, the mold 18 is seen to consist of a bottom section 20 hinged 21 to a side section 22 which is pivotally attached 23 to a second side section 24. The closed mold 18 forms sprues 26 through which the molten material may be poured once the handle sections 28 30 and 32 are connected. 
     The molten material passes through the gates 34 into the mold cavities proper 36. The mold cavities proper 36 are kept in proper alignment by the insertion of the pins 38 and 40 attached to mold section 24 into the body of mold section 22 to provide vertical rigidity to the mold and the insertion of vertical pin 42 mounted in the bottom section 20 into the side section 24 to provide for lateral rigidity. The molten material 44 can be poured from a ladle 46 into the sprues 26.
