Abstract: A set of attachments which affix to a steel tape rule comprising a zero attachment which attaches adjacent to the zero end of the steel tape rule, and a case attachment which attaches to the case of the steel tape rule, and wherein the attachments each hold a scribing pin, commonly called trammel points, and wherein the zero attachment may additionally or in the alternatively hold a pencil or soapstone or chalk. The zero attachment affixes to the steel tape rule near the zero end of the steel tape rule, while the case attachment affixes to the case of the steel tape rule and when so attached provides for allowing the steel tape rule and the zero attachment to be extended from the case, and then the case attachment locks the steel tape rule in the extended position. Thus lofting, and measurements, as well as scribing arcs of substantial diameter are made easier and significantly faster, with no loss in accuracy.

Abstract: On certain handguns, the firing pin protrudes through the rear of the weapon when the weapon is cocked, as an indication of the condition of the weapon. In the uncocked condition, the weapon is held in a holster by the retaining strap which has a conventional female snap which mates with a male snap mounted on the weapon around the firing pin extension orfice. Grasping the weapon, in the holster, and cocking the weapon by depressing the squeeze cocker, automatically cocks the weapon causing the firing pin to extend rearward, popping off the female snap and releasing the weapon to be withdrawn from the holster.

Abstract: A home heating system which transfers heat generated in a fireplace, throughout the home using the duct work and furnace fan already installed in a home, having a natural gas fired forced air furnace; said home heating system being an inexpensive, simple closed loop system compatible with the existing forced air furnace heating system.

The regular bolt assembly comprises a front bolt, a plurality of rails and a rear bolt, wherein the rails connect, and rigidly position the front bolt with respect to the rear bolt. The front bolt has two firing faces, and to change from one firing face to the other, the rails are disconnected from the front bolt, the front bolt reversed and the rails reconnected to the front bolt.

Abstract: A hiker's hatchet with a knife sheathed in the handle of the hatchet whereby the grip of the knife also forms the grip of the hatchet, but when belt carried the knife may be removed without removing the hatchet from the belt, and when used as a fish knife the knife protrudes beyond the hatchet head, thereby in one unit providing a skinning and cleaning knife and a beheading hatchet.

Abstract: A safety mechanism for firearms having a sear pivoting in front of a trigger, wherein the safety mechanism consists of a safety shaft which is rotatably installed transversely to the axis of the barrel; said safety shaft providing positive safe and fire positions by blocking or freeing sear movement; and said safety mechanism also consisting of a safety channel which is affixed to the safety shaft, said safety channel acting as the positioning lever for the safety shaft; and said safety channel being a visible indicator of the position of the safety channel as well as a dust cover and said safety channel blocking access to the trigger when in the safe position; and wherein the safety mechanism can be positioned in the firing mode, and access to the trigger provided by one motion of the safety channel unilaterally with intentionally positioning the trigger finger on the trigger ready to fire.

Abstract: A capotasto for musical instruments that have a finger board, of the guitar type, having an inelastic, tensioned holding strap for connection to the neck of the instrument. This strap, tensioned by a spring, permits repositioning of the capotasto on the neck of the instrument, by rolling without removing the capotasto; and the attachment of the capotasto will not detune the instrument. The capotasto includes two or more rollers on flexible pins to bear on the strings of the instrument to facilitate the repositioning of the capotasto.

Abstract: A device for use by artists and others to aid in freehand sketching, comprising generally a base, a transparent sketching surface in an upright position and a chin rest less than an arm's length away from the sketching surface, said base being supported by nesting folding legs, or being supported by the artists' knees, when the artist is in a sitting position, wherein the artist views the object to be sketched through the sketching surface and sketches directly on the sketching surface.

Abstract: A trigger mechanism for submachine guns and other automatic weapons, having a spring loaded burst finger incorporated into a standard trigger, so that the burst finger bears against the sear in such a way that when the trigger is squeezed the burst finger bears against the sear, turning the sear, and disengaging the sear from the bolt and the trigger to automatically overtravel, blocking the sear from re-engaging the bolt. Trigger rebound repositions the trigger allowing the sear to re-engage the bolt after a short burst of rounds has been fired; then the firer consciously releases the trigger and the trigger returns to its non-firing position. Otherwise full and continued depression of the trigger compels the sear to remain disengaged from the bolt producing a fully automatic firing.

Abstract: The submachine gun also has a forward housing. The forward housing is installed over the forward bolt and barrel, and rotatably secured to the assembly collar, and to the barrel by a sling swivel and a muzzle nut. The forward housing has integrally made there with a pistol grip and trigger housing. The trigger housing contains the trigger mechanism and sear, said sear when the submachine gun is assembled engages selectively the plurality of ring grooves around the forward bolt. Externally attached and mounted to the front housing is a sight bridge. Thus assembled, the front housing with pistol grip and sight bridge may be fully rotated 360.degree. with respect to the stock, magazine, and ejector port while the sear continously engages the ring grooves of the front bolt, and the weapon is ready to fire and fully operable at any point of the 360.degree. rotation.
