Abstract: A pulverizer generally includes a bowl for receiving an object to be pulverized and a pestle movable into the bowl for pulverizing the object. This system has been improved by providing a container which has a depression similar in shape to the shape of the bowl which is received in the bowl and the object is pulverized in the depression of the container to prevent the pulverized material from contaminating the bowl. The container has a flap for covering the depression to hold the pulverized material in the depression. The flap is folded over the depression and locked by a suitable locking mechanism. The pestle has a generally convex but truncated downwardly facing surface which generally conforms to the upper surface of the bowl over the major portion of the exterior, and the bottom surface of the pestle is spaced from the bottom surface of the bowl when the pestle is mated in the bowl.

Abstract: A clothing hanger has a pair of jaws and a pair of arms with each arm connected to a jaw. The arms are pivotally mounted relative to each other to clamp and unclamp the jaws. The arms are biased together, and a member is provided to separate the jaws against the bias. The member is a cam which is mounted for pivoting on one of the arms for camming engagement with the other arm during movement of the cam between a first position with the arms separated in the second position which allows the jaws to clamp under the bias. A cam roller is mounted on the end of the cam which engages the other of the arms to reduce friction of the cam on that arm. A stop is provided for preventing movement of the cam beyond the first position so that the cam is retained in that position. The stop sets the first position such that insertion of clothes against the cam urges the cam a sufficient distance toward the second or closed position so that the biasing force on the arms can close the jaws together.
