Abstract
Abstract A wire saw for cutting stone and other materials, having cutting elements sleeved over multiple strand wires spliced together in endless fashion. The cutting elements are provided at intervals along the length of the wire and secured thereto by a forming operation. Each of the cutting elements has a tubular core, one end portion of which is secured to the wire and the opposite end portion is enlarged internally to be spaced from the wire, and this enlarged portion carries the abrasive cutting material. A coating may be applied over the wire and over the cutting elements for protection thereof.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
111 words
A saw comprising an endless multiple-strand flexible cable, and a plurality of cutting elements sleeved over the cable at intervals along the length thereof, each of said cutting elements including an elongated tubular core having an end portion surrounding a portion of the cable, said end portion being fused around and between the strands, said tubular core having the opposite end portion surrounding a portion of the cable and spaced from the periphery of the cable to permit freedom of flexibility of the cable with respect thereto, and an abrasive cutting element mounted on the last-mentioned end portion of the tubular core and spaced lengthwise thereof from the firstmentioned end portion.
Claim 2
Dependent Claim
111 words
A saw comprising an endless multiple-strand flexible cable, and a plurality of cutting elements sleeved over the cable at intervals along the length thereof, each of said cutting elements including an elongated tubular core having an end portion surrounding a portion of the cable, said end portion being fused around and between the strands, said tubular core having the opposite end portion surrounding a portion of the cable and spaced from the periphery of the cable to permit freedom of flexibility of the cable with respect thereto, and an abrasive cutting element mounted on the last-mentioned end portion of the tubular core and spaced lengthwise thereof from the firstmentioned end portion.
Claim 3
Dependent Claim
20 words
A saw according to claim 1, including a polyurethane coating over the cutting elements and the cable for protectiOn thereof.
Claim 4
Dependent Claim
104 words
A sawing device comprising sheaves spaced apart and having guiding grooves therein, a wire saw extending in bridging relation between the sheaves in the grooves thereof, said wire saw including a cable having cutting elements sleeved thereon in spaced relation in position for guided relation with the grooves, each cutting element comprising a tubular core supporting an abrasive cutting device on one end portion and having the opposite end portion swaged to the cable, and means surrounding the cable intermediate the spaced cutting elements for holding the cable spaced from the bottom of the groove during movement of the cable away from the sheave.
Claim 5
Dependent Claim
104 words
A sawing device comprising sheaves spaced apart and having guiding grooves therein, a wire saw extending in bridging relation between the sheaves in the grooves thereof, said wire saw including a cable having cutting elements sleeved thereon in spaced relation in position for guided relation with the grooves, each cutting element comprising a tubular core supporting an abrasive cutting device on one end portion and having the opposite end portion swaged to the cable, and means surrounding the cable intermediate the spaced cutting elements for holding the cable spaced from the bottom of the groove during movement of the cable away from the sheave.
Claim 6
Dependent Claim
41 words
A sawing device according to claim 3 including a plurality of cutting elements intermediate the first-mentioned cutting elements and disposed in close relation to hold the cable spaced from the bottom of the groove during passage of the wire saw therearound.
Claim 7
Dependent Claim
35 words
A sawing device according to claim 3 including a coating of flexible nonmetallic material covering the cable between the cutting elements and forming the means holding the cable spaced from the bottom of the grooves.
Claim 8
Dependent Claim
87 words
A sawing device comprising sheaves spaced apart and having guiding grooves therein, a wire saw extending in bridging relation between the sheaves in the grooves thereof, said wire saw including a cable having cutting elements sleeved thereon in spaced relation in position for guided relation with the grooves, and a coating of flexible nonmetallic material covering the cable between the cutting elements for holding the cable space from the bottom of the grooves, said coating having peripheral spiral grooves for directing fluid with respect to the cable.
Claim 9
Dependent Claim
87 words
A sawing device comprising sheaves spaced apart and having guiding grooves therein, a wire saw extending in bridging relation between the sheaves in the grooves thereof, said wire saw including a cable having cutting elements sleeved thereon in spaced relation in position for guided relation with the grooves, and a coating of flexible nonmetallic material covering the cable between the cutting elements for holding the cable space from the bottom of the grooves, said coating having peripheral spiral grooves for directing fluid with respect to the cable.
