Patent number: 11885587Abstract: A bow may have a string latch that holds a bowstring and that can be moved into three distinct positions. One activator may be used to prevent the string latch from being moved into its second position. A second activator may be used to prevent the string latch from being moved into its third position. A third activator may be used to move the first and second activators to prevent the string latch from being moved into its second or third positions.Type: GrantFiled: February 27, 2023Date of Patent: January 30, 2024Assignee: Hunter's Manufacturing Company, Inc.Inventors: Michael Shaffer, Richard Bednar, Steven Bednar, Phillip Bednar, Eric Vankeulen, Gary Smith, Jr., Robert Seymour, Keith Bartels

Publication number: 20230393098Abstract: A method of in situ measurement of an acoustoelastic constant (L) of a railway rail, using an ultrasonic wedge sensor to measure a stress-free (unloaded) time-of-flight (t0) in the vertical direction of the rail. Next, a vertical load of known load value is applied to the rail. While the vertical load is applied, the ultrasonic wedge sensor is used to measure a stressed time-of-flight value. The difference between the stress-free and the stressed time-of-flight is calculated to obtain a time-of-flight difference value (?t). Based on the load value, the stress-free time-of-flight value, and the time-of-flight difference value, the acoustoelastic constant, L, may be calculated. The wedge sensor may be further used to measure the (stressed) horizontal time of flight, and a time-of-flight difference value in the horizontal direction may be used to measure longitudinal stress.Type: ApplicationFiled: May 31, 2023Publication date: December 7, 2023Inventors: Xin Chen, Adam C. Cobb, Douglas R. Earnest, Keith A. Bartels

Patent number: 11592258Abstract: A crossbow de-cock mechanism may include a de-cock activator that is selectively movable from a first de-cock activator position that prevents de-cocking of a crossbow into a second de-cock activator position that permits de-cocking of the crossbow.Type: GrantFiled: March 28, 2022Date of Patent: February 28, 2023Assignee: Hunter's Manufacturing Company, Inc.Inventors: Michael Shaffer, Richard Bednar, Steven Bednar, Phillip Bednar, Eric Vankeulen, Gary Smith, Jr., Robert Seymour, Keith Bartels

Patent number: 11428499Abstract: A crossbow may include a bowstring and a string latch that can be moved into a first string latch position that holds the bowstring in a cocked position, a second string latch position that does not hold the bowstring in the cocked position and a third string latch position. To de-cock the crossbow, a de-cock activator may be selectively movable from a first de-cock activator position that prevents the string latch from being moved into the third string latch position into a second de-cock activator position that permits the string latch to be moved into the third string latch position. When the string latch is in the first string latch position and the de-cock activator is in the second de-cock activator position: the string latch may be selectively movable into the third string latch position and then the second string latch position permitting de-cocking of the crossbow.Type: GrantFiled: January 25, 2021Date of Patent: August 30, 2022Assignee: Hunter's Manufacturing Company, Inc.Inventors: Michael Shaffer, Richard Bednar, Steven Bednar, Phillip Bednar, Eric VanKeulen, Gary Smith, Jr., Robert Seymour, Keith Bartels
