Abstract: The invention relates to a novel barrette structure useable in the manner of similar prior art structures and alternately capable of 360.degree. rotation about the closed end thereof to facilitate styling of the hair.

Abstract: The invention is a plectrum or pick for a guitar or other stringed musical instrument played with a pick. In particular, the invention is a pick and pick holder conformable to the contours of the forearm of a wrist amputee, the invention also providing a method for making the present prosthetic pick structure.

Abstract: A new and improved band tensioning device or clamp is provided for securing and maintaining the required tension of chain link fences or the like. This clamp consists of a flat strip of cut metal formed into a U-shape.The closed end of the clamp is placed around a fence post and the two arms with curved ends are pressed together and locked around a tension bar which has been threaded through a chain fabric type fence.

Abstract: A lathe cutting tool is provided for cutting helix grooves into rubber covered rolls for use in polishing of stainless steel strip or the like. This cutting tool consists of a shaft having a cutting blade means mounted at one end thereof. A traction wheel is provided in parallel relationship with the cutting means for engaging the surface of the rubber covered roll, and means are provided for mounting the traction wheel for rotation and parallel to the cutting blade means. Bracket means are provided for mounting said shaft to a lathe for movement therealong so that the cutting tool can be used to cut helix grooves in a rubber covered roll as desired.

Abstract: A snap-in and snap-out shell catcher is provided for use on multiple shot semi-automatic guns. It has a shell ejection port mechanism which consists of a fixed plate and a movable plate (arm), a latch and spring arrangement, and a spring-wire hoop and loop, all of which are formed into one unit. The mechanism is readily attached to the side of the receiver of a gun.The arm is attached to the fixed plate in such a manner that it can pivot around a single point near the center of the arm. The extent and timing of this pivoting action of this arm is limited and controlled by the latch and spring arrangement in conjunction with the normal firing and subsequent operation of the action of the gun on which it is fitted.The spring-wire hoop and loop is attached to the forward muzzle end of the arm in such a manner that when the forward end of the arm is pivoted upwardly, the spring-wire hoop and loop will be positioned over the shell ejection port of the gun.

Abstract: A portable cooking grill is provided which can be used on open fireplaces and the like. This grill consists of a plurality of parallel spaced metal rods which are held together by a series of inner and outer metal connectors placed along each side of the grill. The parts are maintained in position by crimping the ends of the rods on opposite sides of the connectors. The inner and outer connectors are so designed that the cooking grill can be opened up to be in a flat rigid plane, or rolled up to be positioned in a small container for storage purposes.

Abstract: The invention generally relates to vertical rotisserie structures wherein arcuate heating elements direct heat onto a foodstuff held on a spit mounted in the general focus of the heating elements. The present invention particularly provides a plurality of cooking platforms vertically arranged on a rotatable spit, each platform holding a plurality of portion-controlled foodstuffs for heating by opposed arcuate heating elements. The portions of the foodstuff are mounted on passive pivots which are caused to rotate in response to a fixed structural bias on rotation of the spit itself.

Abstract: A frame assembly is provided having an outer frame and an inner frame secured to the outer frame. Mounting boards are provided on either side of the inner frame. Pairs of spaced slots are provided on the inner surface of the outer frame and arranged on opposite sides of the inner frame for receiving mounting fixtures for mounting the frame assembly in either a reversed, horizontal or vertical position.

Abstract: An endometrial tissue-obtaining instrument includes a spiral section formed at one end of a flat plastic member and a handle portion at the other end. The spiral section is insertable into the womb of a female patient and rotated by the handle portion to remove endometrial tissue from the wall of the womb. The spiral section is withdrawn with the specimen of tissue.The trailing portion of the spiral section is inserted into a slot of a plastic paddle and pulled away from the paddle so that the spiral section moves through the slot and is rotated thereby. The thickness of the slot permits the wiping, or extruding, of the tissue from the spiral section onto the paddle whereafter the paddle is manipulated to deposit the tissue onto a slide or stored for future purposes.
