Abstract

A dual chamber condiment grinder has more than one chamber for holding a different condiment in each, and each chamber has a rasp that can be selectively moved up and down to grind the condiment in the associated chamber. An actuating handle rotates on the top of the chambers to position a cam over one or the other of the rasps to selectively grind the contents of one of the chambers. In the alternative, the cam can move in a slot in a movable handle to position the cam over the desired rasp.

Claims

1. A multiple chamber condiment grinder, comprising:

2. The grinder of claim 1, wherein the first and second handles are rotatably mounted on the chambers for selectively positioning the cam over the first or second rasp.

3. The grinder of claim 1, wherein the cam of said movable second handle is movable relative to said second handle from said first position over the first rasp to said second position over the second rasp.

4. The grinder of claim 1, said first rasp having spaced forks projecting therefrom overlying the spring, the spaced forks forming an opening therebetween, said second rasp having a tongue projecting therefrom and extending into the opening between said forks also overlying the spring.

5. The grinder of claim 4, further comprising a vertical pin between the rasps and beneath the fork and the tongue of the rasps, the pin having an enlarged top selectively engageable with the fork or the tongue, said spring encircling the pin and being compressed by downward movement of the pin.

6. The grinder of claim 2, said chambers each having a top wall, said top walls being joined and forming a circular opening, a collar fixed in said opening, the collar having a circular horizontal groove, said handles being joined to have a circular flange, the flange of the handles fitted within the groove of the circular collar for rotatably guiding the handles to the first and second positions.

7. The grinder of claim 1, at least one of said shear blocks being adjustable to vary the size of the discharge gap between the shear block and the shearing edges of the rasp for changing the coarseness of the ground condiment.

8. The grinder of claim 6, wherein said first rasp has spaced forks projecting therefrom overlying the spring, the spaced forks forming an opening therebetween, said second rasp has a tongue projecting therefrom and extending into the opening between said forks also overlying the spring, a vertical pin between the rasps and beneath the fork and the tongue of the rasps, the pin having an enlarged top selectively engageable with the fork or the tongue, said spring encircling the pin and being compressed by downward movement of the pin.

9. The grinder of claim 1, wherein said first rasp having spaced forks projecting therefrom overlying the spring, the spaced forks forming an opening therebetween, said second rasp having a tongue projecting therefrom and extending into the opening between said forks also overlying the spring, a vertical pin between the rasps and beneath the fork and the tongue of the rasps, the pin having an enlarged top selectively engageable with the fork or the tongue, said spring encircling the pin and compressed by downward movement of the pin.

10. The grinder of claim 1, further comprising an indicator that displays to a user a name of the first condiment when the cam is in the first position and a name of the second condiment when the cam is in the second position.

11. The grinder of claim 10, wherein the indicator includes a fixed collar around which the first and second handles rotate, names of the first and second condiments being positioned on opposite sides of the collar, a window being provided in one of the first and second handles aligned with the names on the collar, the name of the first condiment being visible through the window when the cam is in the first position and the name of the second condiment being visible when the cam is in the second position.

12. A dual chamber condiment grinder having first and second chambers that are spaced and separate from each other, each chamber holding a condiment to be ground, each having a top wall and a bottom wall; means in each chamber for grinding the condiment in that chamber, a handle attached to the top of the chambers, said handle being operable to selectively actuate the means for grinding the condiment in one or the other of the first and second chambers; and

13. The grinder of claim 12, said handle including a pivotable member having a cam engageable with the top region of a rasp, and a fixed member, said handle being mounted above the chambers, said cam being movable relative to the handle to be positioned selectively over one or the other of the rasps.

14. The grinder of claim 12, said handle including a pivotable member having a cam engagable with the top region of a rasp, and said handle being rotatable to selectively position the cam over one or the other of the tops of the rasp.

15. The grinder of claim 12, wherein said first rasp has spaced forks projecting therefrom overlying the spring, the spaced forks forming an opening therebetween, said second rasp having a tongue projecting therefrom and extending into the opening between said forks also overlying the spring.

16. The grinder of claim 15, wherein a vertical pin is positioned between the rasps and beneath the forks and the tongue of the rasps, the pin having an enlarged top selectively engageable with the forks or the tongue, said spring encircling the pin and compressed by downward movement of the pin.

17. The grinder of claim 12, wherein said handle is rotatably mounted on the chambers for selectively actuating the grinding means of a respective chamber.

18. A dual chamber condiment grinder having first and second chambers that are spaced and separate from each other, each chamber holding a condiment to be ground, each having a top wall and a bottom wall; means in each chamber for grinding the condiment in that chamber, a handle attached to the top of the chambers, said handle being operable to selectively actuate the means for grinding the condiment in one or the other of the first and second chambers; and

19. A dual chamber condiment grinder having first and second chambers that are spaced and separate from each other, each chamber holding a condiment to be ground, each having a top wall and a bottom wall; means in each chamber for grinding the condiment in that chamber, a handle attached to the top of the chambers, said handle being operable to selectively actuate the means for grinding the condiment in one or the other of the first and second chambers; and

20. The grinder of claim 19, wherein the indicator includes a fixed collar around which the handle rotates, names of the first and second condiments being positioned on opposite sides of the collar, a window being provided in the handle aligned with the names on the collar, the name of the first condiment being visible through the window when the handle is positioned to actuate the means for grinding the condiment in the first chamber and the name of the second condiment being visible through the window when the handle is positioned to actuate the means for grinding the condiment in the second chamber.
