Abstract:
A device for indicating attainment of a predetermined compressive load applied to said device, said device being formed to receive an anchor member upon which a tensioning force is to be applied in conjunction with loading said device, said device comprising:a. an upper press, having an aperture formed to receive said anchor member and also having means for manipulating a washer;b. a lower die, having an aperture formed to receive said anchor member, said lower die formed so as to be able to work in conjunction with said upper press when said upper press and lower die are aligned and moved towards each other, said lower die also having means for manipulating said washer, said means for manipulating said washer being formed to cooperate with said means for manipulating said washer on said upper press; andc. said washer lying between said upper press and said lower die, said washer being formed so that when said washer is acted upon by said means for manipulating said washer of said upper press and said lower die it will indicate visually whether a selected compression load has been applied to said washer, said washer member also having one or more inner portions that are formed so that when said washer is acted upon by said means for manipulating said washer, said one or more inner portions can extend inwardly toward said anchor member and can be pressed into said anchor member.
