This disclosure depicts a novel method and apparatus for determining the amount of material to be removed in a door jamb for the installation of an electric door strike. In particular, the apparatus comprises a template comprised of an elongate paperlike sheet in the shape or outline of the front view of the electric door strike to be installed in the door jam, the template having an open area therein through which measurement markings made on the door jam are aligned through the template, the template also having an adhesive material on the back thereof for securing the template firmly to the door jamb while the outline of the door strike is traced onto the jamb. The method described herein is for the purpose of practicing the above-mentioned determination of material to be removed from the door jamb.

Template for installation of electric door strikes

This disclosure depicts a novel environmentally sealed and manually controlled swivel unit for use in an adjustable lighting fixture. The swivel unit comprises a base for establishing electrical and mechanical connection with a source of electrical power and is attached to a housing having a central housing bore. The swivel unit further comprises a swivel ball device having a spherical body and a tube extending from the spherical body with a means for sealing the swivel ball device within the housing. A lamp-holder is attached to the end of the tube. The swivel unit also comprises a minimum friction swivel ball controller and circular plate and a tension means for forcing the swivel ball controller against the swivel ball device, and, in turn, for forcing the swivel ball device against a shoulder of the housing. This defines a predetermined lamp-holding force. The swivel ball controller allows the swivel ball device to rotate about a first axis and also to rotate about a second axis perpendicular to the first axis. The swivel ball device and the shoulder on the housing form an environmentally sealed juncture.

The swivel ball controller allows the swivel ball device to rotate about a first axis and also to rotate about a second axis perpendicular to the first axis. The swivel ball device and the shoulder on the housing form an environmentally sealed juncture. The predetermined lamp-holding force retains the swivel ball device at any selected position while allowing easy manual movement of the swivel ball device. By a combination of rotations about the first and second axes, the apparatus can direct light to any objective oriented hemispherically with regard to the two axes while maintaining environmental integrity.
