A sliding charge receiver is slidably positioned under a powder feed hopper for receiving a charge from the hopper and delivering it to a feed chute. The sliding member has a hole to receive a powder charge from the hopper. The hole is adjustable in size by a safety adjustment. The hole is formed in the end of a slot. A secondary slider is movable in the slot to adjust the size of the hole. The secondary slider is on a threaded stem within the slot which is threaded through a rotatable bushing or rotor. The stem can be locked in position by an elongated nut that extends through a hole in the end of the sliding member. By releasing the elongated nut, the secondary slider, threaded stem and rotor can be rotated, moving the secondary slider out of the slot so that the secondary slider and stem can be rotated to provide fine adjustments of the position of the secondary slider and of the charge hole in the sliding member with assured safety of the adjustment.
In apparatus for measuring and dispensing flowable material;
Apparatus having a powder hopper that has a powder discharge passage in combination, a powder measuring and dispensing apparatus for measuring charges of powder including means providing a slideway, a sliding member slideable in the slideway and having an opening positionable to register with the end of the said discharge passage, the said sliding member including a channel having a secondary slideable member carried by it in the channel, the end part of said channel forming said opening, means within said channel for locking the secondary slideable member in position, said last means including a threaded member, a threaded stem engaging with said secondary slideable member and threaded member, the said channel opening to one side, the said secondary slideable member and threaded stem being pivotally mounted whereby to be movable outwardly laterally through said channel opening for adjustment of the secondary slideable member to adjust the size of said opening.
In apparatus for measuring and dispensing flowable material;
Apparatus having a powder hopper that has a powder discharge passage in combination, a powder measuring and dispensing apparatus for measuring charges of powder including means providing a slideway, a sliding member slideable in the slideway and having an opening positionable to register with the end of the said discharge passage, the said sliding member including a channel having a secondary slideable member carried by it in the channel, the end part of said channel forming said opening, means within said channel for locking the secondary slideable member in position, said last means including a threaded member, a threaded stem engaging with said secondary slideable member and threaded member, the said channel opening to one side of said slideway, the said secondary slideable member and threaded stem being movable outwardly through said channel opening for adjustment of the secondary slideable member to adjust the size of said opening, said threaded member being mounted to be rotatable with respect to said sliding member to accommodate movement of the secondary slideable member and threaded stem outwardly through the said channel opening for adjustment, a lock member extending through an end part of said slideable means and positioned in axial alignment with said threaded stem whereby it can be threaded onto an end of said threaded stem to lock it to prevent misadjustment of the said secondary slideable member.
