Material Compacting Device (Patent No: 962522)

Inventor: Wollersheim, Philip

Location: Calgary

Comments: N/A

Description: WHAT I CLAIM AS MY INVENTION IS:

1. A material compacting device for use in conjunction with a storage container such as a truck; comprising in combination an outer casing, an arcuately curved shroud mounted in said casing, an intake hopper in said casing and an ejector outlet in said casing, said shroud extending between said hopper and said outlet, a drum journalled for rotation transversely within said casing and being situated towards said outlet, the peripheral wall of said drum being in close proximity with the concave inner surface of said shroud, a source of power operatively connected to said drum for rotating same and a set of compression vanes, means in said casing to mount said vanes, said means being eccentric to the transverse axis of said drum, said vanes extending through the peripheral wall of said drum and extending and retracting relative to said peripheral wall of said drum as said drum rotates, adjacent vanes, the portion of said peripheral wall therebetween and said shroud defining chambers, the volume of which decreases towards said ejector outlet as said drum and vanes rotate, said shroud being pivotally mounted to said casing by one end thereof adjacent said hopper and adjustable means adjacent the other end thereof normally biasing said shroud towards said drum thereby controlling the compaction of material within said chambers.

2. The device according to Claim 1 in which said means in said casing mounting said vanes includes a fixed shaft spanning said casing internally of said drum and being secured to the walls of said casing, sleeve bearing means secured to the walls of said casing, sleeve bearing means secured to each of said vanes and bearably engaging around said shaft, transverse slots formed in the peripheral wall of said drum, one for each of said vanes, and bearing means on the insides of said drum wall adjacent each slot for bearably supporting each of said vanes for reciprocal motion through said slots.

3. The device according to Claim 1 which includes means for journalling said drum for rotation as aforesaid, said last means including a plurality of rollers journalled upon each side wall of said casing and situated within said drum, the inner surface of the peripheral wall of said drum engaging over said rollers at each end of said drum.

4. The device according to Claim 2 which includes means for journalling said drum for rotation as aforesaid, said last means including a plurality of rollers journalled upon each side wall of said casing and situated within said drum, the inner surface of the peripheral wall of said drum engaging over said rollers at each end of said drum.

5. The device according to Claim I in which said means normally biassing said shroud towards said drum includes a compression spring reacting between said outer casing and said shroud and a spring cup on said shroud receiving one end of said spring.

6. The device according to Claim 2 in which said means normally biassing said shroud towards said drum includes a compression spring reacting between said outer casing and said shroud and a spring cup on said shroud receiving one end of said spring.

7. The device according to Claim 3 in which said means normally biassing said shroud towards said drum includes a compression spring reacting between said outer casing and said shroud and a spring cup on said shroud receiving one end of said spring.

8. The device according to Claim 4 in which said means normally biassing said shroud towards said drum includes a compression spring reacting between said outer casing and said shroud and a spring cup on said shroud receiving one end of said spring.

CLAIMS SUPPORTED BY SUPPLEMENTARY DISCLOSURE

9. The device according to Claim 1 in which said means normally biassing said shroud towards said drum includes a fluid operating piston and cylinder assembly operatively extending between said shroud and said casing and an accumulator in said casing operatively connected to the cylinder of said piston and cylinder assembly.

10. The device according to Claim 2 in which said means normally biassing said shroud towards said drum includes a fluid operating piston and cylinder assembly operatively extending between said shroud and said casing and an accumulator in said casing operatively connected to the cylinder of said piston and cylinder assembly.
11. The device according to Claim 3 in which said means normally biassing said shroud towards said drum includes a fluid operating piston and cylinder assembly operatively extending between said shroud and said casing and an accumulator in said casing operatively connected to the cylinder of said piston and cylinder assembly.

12. The device according to Claim 4 in which said means normally biassing said shroud towards said drum includes a fluid operating piston and cylinder assembly operatively extending between said shroud and said casing and an accumulator in said casing operatively connected to the cylinder of said piston and cylinder assembly.
