Multiple chamber condiment grinder
View Patent ↗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.
1. A condiment grinder, comprising:
a first chamber for holding a first condiment to be ground;
a second chamber from the first chamber for holding a second condiment to be ground;
first and second shear blocks being positioned at least proximate each of the first and second chambers respectively;
a first rasp positioned proximate the first shear block and a second rasp positioned proximate the second shear block, each of the first and second rasps having a top region, and shearing edges operatively spaced from said shear block defining a respective discharge gap and for grinding a condiment between each rasp and the corresponding shear block and discharging the ground condiment through the discharge;
a movable handle engageable with the top region of one of the first and second rasps for moving the rasp and the shearing edges of the rasp with respect to the shearing block to grind the condiment;
a biasing member engageable with each rasp for returning the rasp to a resting position following actuation; and
said handle being coupled to said chambers to be selectively moved between a first position wherein the handle can activate the first rasp and a second position wherein the handle can activate the second rasp, whereby the rasps can be selectively actuated for grinding the condiment in the desired chamber.
2. The grinder of claim 1 wherein the handle is rotatably mounted to the condiment grinder for selectively actuating the first or second rasp.
3. 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 having a circular flange, the flange fitted within the groove of the circular collar for rotatably guiding the handle between the first and second positions.
4. The grinder of claim 1 wherein the handle comprises a cam from said first position over the first rasp to said second position over the second rasp.
5. The grinder of claim 1 , said first rasp having spaced forks projecting therefrom overlying the biasing member, 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 biasing member.
6. The grinder of claim 5 , 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 biasing member encircling the pin and being compressed by downward movement of the pin.
7. The grinder of claim 1 , at least one of said shear blocks being selectively moveable 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 3 wherein said first rasp has spaced forks projecting therefrom overlying the biasing member, 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 biasing member, 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 biasing member 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 biasing member, 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 biasing member, 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 biasing member encircling the pin and compressed by downward movement of the pin.
10. The grinder of claim 1 , further comprising an indicator that displays an identifier of the first condiment when the cam is in the first position and identifier 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 handle rotates, the identifiers of the first and second condiments being positioned on opposite sides of the collar, a window being provided in the handle aligned with the identifiers on the collar, the identifier of the first condiment being visible through the window when the cam is in the first position and the identifier of the second condiment being visible when the cam is in the second position.
