Abstract: A belt grill is described herein for continuously cooking fast food products on a conveyor formed of counter-rotating heat conductive belts. The belts are heated by platens disposed above and below whereby a run of the belts passes in heat conductive relationship between the platens, and the food to be cooked is placed in the nip between the rotating belts. The device further includes means for tensioning the belts which can be automatically released by increasing the distance between the platens whereby when the distance exceeds a predetermined maximum, all tension on both belts will be released so that the belts can be quickly removed for cleaning or replacement. The belts are preferably Teflon coated fiberglass and may be disposed at an angle to the horizontal to facilitate grease removal from the cooking process.

Abstract: A rubber stamp comprising a housing (13, 14), a base plate (12) fixed at one end of the housing and a handle in the form of a knob (15, 16) mounted at the other end of the housing. A stamp block (24) formed by independently-changeable rubber stamp elements carried by endless rubber bands (25) rotatable in the housing, protrudes through an aperture (23) in the base plate (12). To change the stamp block, the rubber band assembly is withdrawn by axial movement of the knob (15, 16) so as to bring the stamp block within the housing, and the rubber bands are then rotated to set a new stamp block within the housing. Rotation of the rubber bands (25) is effected by respective wheels (31) acting through respective sprocket wheels (56) over which the rubber bands pass. The peripheries of the wheels (31) protrude through slots (33) in a wall of the housing.
