Abstract
A demountable pin for rotatably connecting together two elements of small axial dimension, consisting of a bolt with a frusto-conical under-head and an inner hexagonal through bore for tightening it by a key. The pin is locked between two frusto-conical flares of the elements by an end nut with a frusto-conical under-head and a washer with a frusto-conical surface of greater taper than the flares. The under-heads of the nut and the bolt cooperate with the flares.
Claims5
A demountable pin for insertion through and clamping together two frusto-conical flares sandwiching an element therebetween, each of said frusto-conical flares being formed in plate cheeks, said element being rotatably connected to said plate cheeks and having a pin passage and rotation bearing, said pin passage being aligned with said rotation bearing, said pin having a bolt with a frusto-conical under-head rigidly mounted thereto and an internal through bore, said pin being detachably affixed to an end nut after said pin is inserted through said two frusto-conical flares, said end nut also having a frusto-conical under-head, the frusto-conical under-heads of both the bolt and the nut having a taper substantially equal to a taper of said frusto-conical flares of said two cheeks, said frusto-conical under-head of said bolt being engaged with a washer having a frusto-conical surface when said pin is inserted through said two frusto-conical flares, the frusto-conical surface of said washer having a taper which is greater than the taper of said frusto-conical flares of said two cheeks.
