Abstract: An eye-bolt assembly includes an eye bolt and a base portion. The eye bolt includes a ring portion, a stem portion, and at least one winged extension. The ring portion is attached a first end of the stem portion. The at least one winged extension is attached to a second end of the stem portion. The base portion receives and securely locks the eye bolt therein. The base portion includes a collar and a platform secured to the collar. The collar forms a first aperture therein. The platform forms a second aperture therein. The platform includes a spring being located at least partially within the second aperture. A first end of the spring is attached to the platform. The second aperture formed in the platform is in spaced communication with the first aperture formed in the collar.

Abstract: An eyebolt assembly is provided in which a skirt member is reinforced by radially projecting diametrically extending ribs. A fixed lifting eye projects from one side of the skirt, and a mounting stud projects from the opposite side. The mounting stud is double threaded with one thread being adapted to mate with a threaded bore in the body of the eyebolt assembly, and the other thread being matched to a threaded bore in a load. The same eyebolt body can be employed with a plurality of different mounting studs, which simplifies inventorying eyebolt assemblies to meet all of the different threaded bores that may occur in different loads. Only the mounting studs need to be threaded to match the loads. The skirts are provided with striking faces so that they can be tightened and loosened by striking them with a hammer.

Abstract: An eyebolt inventory control method in which a plurality of eyebolt bodies are provided. The eyebolt bodies all have about the same nominal dimensions and they include a skirt member that is reinforced by radially projecting diametrically extending ribs. The skirts are provided with striking faces so that they can be tightened and loosened by striking them with a hammer. A fixed lifting eye projects from one side of the skirt, and a mounting stud projects from the opposite side. The mounting stud is double threaded with one thread being adapted to mate with a threaded bore in the body of the eyebolt assembly, and the other thread being matched to a threaded bore in a load. The same eyebolt body can be employed with a plurality of different mounting studs, which simplifies inventorying eyebolt assemblies to meet all of the different threaded bores that may occur in different loads. Only the mounting studs need to bear threads that match the threads in the loads.

Abstract: A needle tube lock for a tattoo machine. The lock has a clamp arm which receives a threaded fastener and a needle tube arm which has a bore which receives the needle tab. The arms are integrally formed from stainless steel or other suitable sterilizable material. The lock is positioned about the needle tube and may be rotated relative to the needle tube retainer to a selected position and secured by tightening the fastener against the retainer. In this way, the tattoo machine is usable even if the retainer is broken or damaged.

Abstract: A reusable end finishing apparatus for rope, cord, wire, cable and the like is provided. The end finishing apparatus has an outer rigid sleeve, an inner compressible barbed gripping member which engages the end to be finished, and an eyebolt which has a threaded rod which extends through holes in both the compressible gripping member and the outer rigid sleeve. In assembly for use, the termination of the device to be finished is threaded through the eyebolt and doubled back. The eyebolt is then placed in the compressible gripping member with grooves in the gripping member provided for the eyebolt eye. The threaded rod end of the eyebolt is moved through a hole in the compressible gripping member until the eye of the eyebolt bottoms in the gripping member.

Abstract: A swivel base assembly for mounting radio apparatus or the like on a supporting surface includes a first support element for engaging the apparatus housing and a second support element for engaging the supporting surface. A spacing element in the form of a sphere allows relative movement between the support elements while maintaining a fixed minimum spacing. Locking means in the form of interlocking hook members draw the mounting plates into engagement with the spacer element to fixedly position the first plate with respect to the second plate and the supporting surface.
