TL;DR: A portable gem faceting kit is described in this paper, which includes a portable carrying case that may be opened to a use position in which it constitutes a utility rack from which other items of the kit may be retrieved and conveniently used.
Abstract: A gem faceting kit is disclosed which includes a portable carrying case that may be opened to a use position in which it constitutes a utility rack from which other items of the kit may be retrieved and conveniently used. The gem faceting kit includes a gem faceting machine that has a storage and a use position. Also included in the kit are various lap wheels, grinding compounds, a rinse dispenser, a catch basin, a lamp, a visor, and various other tools, chemicals, and compounds used in gem faceting. The entire kit is lightweight and portable.

TL;DR: In this article, a collet chuck is mounted on a dop arm and a plug is received within an open longitudinal bore formed within the socket, which is used to adjust the collet's position relative to the dop's axis.
Abstract: Apparatus as described for centering a collet chuck relative to the longitudinal axis of a dop arm for a gem faceting machine. The apparatus includes a socket mounted to the dop arm and a plug slidably received within an open longitudinal bore formed within the socket. The plug mounts a collet chuck. Two longitudinally spaced sets of screws extend radially into the socket. The individual screws of the two sets can be turned against the plug to adjust the collet chuck into a secure precise coaxial relation with the dop arm axis.

TL;DR: Gemstones are cut such that the pavillion facets are curved facets (12,14,16) and are arranged in pairs around the pavillon and so disposed relative to each other and the crown and table of the gemstone that light entering the stone through a crown and meeting the first curved facet of a pair is converged and reflected on to another curved facet from which it is reflected to the crown; faceting machine for producing such facets is disclosed as discussed by the authors.

TL;DR: In this article, a diamond faceting machine is used to orient a gemstone for forming facets thereon in a plurality of coaxial rows with equal spacing of the facets in the rows.
Abstract: A gemstone faceting machine for properly orienting a gemstone for forming facets thereon in a plurality of coaxial rows with equal spacing of the facets in the rows. A dop stick is provided on the end of a faceting shaft secured in a quill sleeve rotatably mounted in a faceting head (which can be angularly adjusted for different facet rows to be formed). A spring-biased detent trigger is pivoted on the bracket to engage between the teeth of an indexing gear secured on a collar on the quill sleeve near the other end of the shaft. A positioning pin is secured to the collar and projects through the gear. A guide disc having evenly spaced peripheral notches is engaged around and can be rotated on a flanged bushing threadably engaged on the quill sleeve adjacent the gear, and a coil spring is provided on the bushing, urging the disc toward the gear. The disc has respective holes spaced to receive the pin to establish the angular relationship between the successive rows of evenly spaced facets. The notches on the disc guide the detent trigger into engagement between the gear teeth for assuring uniform angular rotational steps of the shaft in forming the facets of a particular row.
