Patent number: 4378934Abstract: An apparatus is disclosed for re-claiming used or damaged tube turns and rendering them equivalent to new tube turns with correctly oriented openings. A salvaged tube turn is temporarily fixed to a platform in a position such that the longitudinal axis of one of tube turn ends is approximately perpendicular to the plane of an adjacent circular track. The platform is moved so that the opening of the tube turn end is near the circular track. The circular track is then accurately centered with respect to the opening by use of a spider or the like which is temporarily fixed to the center of the track. Either the spider (and track) or the tube turn is moved so that the spider engages the interior of the opening.Type: GrantFiled: June 5, 1980Date of Patent: April 5, 1983Inventor: George W. Tucker

Patent number: 4283043Abstract: A system for using a cutting torch for making accurate curved, straight and beveled cuts. A supporting and guiding device is attached to cutting torches, which may be of various sizes and shapes, and includes an elongated bar having a ring and opposed set screw clamp at one end to receive the torch tip. A member on the elongated bar carries a workpiece engaging knife-edge wheel and supports the lower parallel tube of the torch, this member being removably mounted on and slidable along the bar to desired positions. The height bar above the wheel is adjustable for positioning the burning tip at the correct angle and spacing with respect to the workpiece. The wheel can be positioned with its plane transverse to the bar for making curved or lateral cuts, or parallel to the bar for making longitudinal straight, perpendicular or bevel cuts. A centering pin is slidably positionable on the bar for making long radius cuts.Type: GrantFiled: October 12, 1979Date of Patent: August 11, 1981Inventor: Alan Kalian

Patent number: 4194727Abstract: Shape cutting apparatus includes a transverse beam rigidly mounted on a pair of spaced carriages which are provided with wheels for translation along a pair of parallel, longitudinal rails. A tracer and holder assembly therefor are mounted for translation along the transverse beam. Each carriage is provided with a servomotor, which motors are connected electrically in parallel across a source of potential such as the output of a servoamplifier. Upon energization of the motors, the beam is driven along the rails at speeds up to 120 i.p.m. and greater while the tracer cornering capability is equivalent to the capability previously only attainable at lower speeds, e.g. 50-60 i.p.m. Thus, higher cutting speeds are obtained without degradation of cutting accuracy and without resort to expensive structural stiffening, additional electronic control circuitry, or precision rack and pinion carriage drive mechanisms.Type: GrantFiled: February 7, 1979Date of Patent: March 25, 1980Assignee: Airco, Inc.Inventors: Lawrence M. Layden, James R. Thomson

Patent number: 4148467Abstract: A pipe having a guide pattern or template mounted on and surrounding it is rotatable about its longitudinal axis while a pattern follower actuates a cutting or welding tool to move longitudinally as the pipe rotates. The follower and tool are carried by a frame supported on the pipe by rollers. The frame is mounted on a support for universal tilting and for horizontal sliding in one direction to ensure that the follower and tool bear a constant relationship to the pipe irrespective of any undulations or out-of-round features of the pipe.Type: GrantFiled: December 12, 1977Date of Patent: April 10, 1979Inventor: Eugene F. Sargeant

Patent number: 4134576Abstract: A safety carriage for supporting and guiding an acetylene torch in which the torch nozzle can be spaced a desired distance above the work being cut by the flame and the carriage has an asbestos lined pan underlying the operator's hand for protecting it. The device can be guided along a line which is to be cut by the torch flame. An anti-glare shield supporting frame can be attached to the torch for protecting the operator's eyes and this same frame also supports an asbestos shield which is positioned directly behind the torch nozzle and in front of the pan to prevent sparks from the torch flame striking the operator's hand. A frame supporting cross arm with rollers at its ends can be used for moving the torch nozzle in an arc for making a circular cut having a large radius or a center pivot can be substituted for cutting a smaller circle.Type: GrantFiled: September 6, 1977Date of Patent: January 16, 1979Inventor: Lester R. Livick
