Appl. No.:

15/946142

Inventors:

- Langhorne PA, US
David L. Sharp - Warrington PA, US

Assignee:

TurnaSure LLC - Langhorne PA

International Classification:

F16B 31/02

Abstract:

A direct tension indicating (DTI) washer. The DTI washer has an annular body and one or more U-shaped horseshoe protuberances. The annular body includes a central hole, a circumference, an outer edge, a first face, and a second face opposite from the first face. The horseshoe protuberances each have a height, an apex closest to the central hole, and an opening directed toward the outer edge. The horseshoe protuberances are integral with the annular body and struck and partially sheared from the annular body to project from the first face of the annular body and leave one or more corresponding indentations in the second face of the annular body. The horseshoe protuberances may be radially offset from their corresponding indentations. An indicating material is initially encapsulated and contained within the area on the first face defined by each of the horseshoe protuberances.

15/007507

Inventors:

David Sharp - Bethlehem PA, US

International Classification:

B25B 5/06
B25B 27/14

Abstract:

A ratcheting spreader system includes a construction frame that has a pair of lateral arms. A spreader has a first half is slidably coupled to a second half. The spreader includes an urging unit extending between the first half and the second half. The urging unit may be manipulated thereby spacing the first half a selected distance from the second half. The spreader is selectively positioned between the lateral arms such each of the first half and the second half engages an associated one of the lateral arms. The urging unit urges each of the lateral arms a precise distance apart from each other. Thus, the lateral arms may be secured during construction.

International Classification:

Abstract:

A direct tension indicating washer including an annular body with a central hole, one or more protuberances, and one or more indentations. The one or more protuberances are integral with the annular body, and struck and partially sheared from the annular body to project from a first face of the annular body and leave the one or more corresponding indentations in a second face of the annular body opposite the first face. The one or more indentations are offset from the one or more protuberances and located farther from the central hole of the annular body than the one or more protuberances. By offsetting the protuberances and indentations, the washer is strengthened and is more suitable for use in joint assemblies having enlarged or oversized holes.
