The holding clip is preferably made of metal and can be secured in the receiving orifice by a clamp.

An activating pin which comprises a valve part, the piston part comprises within it a channel, the cross-section of said channel is, at least one part of said piston part, consisting of sectors, wherein in each sector the distance between the center point of the channel cross-section and the outermost limiting surface of the channel is larger than the corresponding distance measured along the line separating the sector from an adjacent sector, and said valve part is positioned movably with respe...

A pin bearing lubrication system is described which comprises a pin bearing having a bush recessed each end thereof; a sealing ring disposed in each recess in the bush; a bearing pin passing through the bush and forming seals with the sealing rings; a reservoir for lubricant formed in the bearing pin; a duct formed the bearing pin connecting the reservoir with bearing surfaces formed between the bush and the bearing pin; and a diaphragm movable in and relative to the reservoir, the arrangement b...

A loop-shaped spring member has mutually opposite ends, which are pivoted to a pin member adjacent to each other near one end of said pin member. The spring member has an intermediate portion which is pivotally movable about said ends of said spring member into and out of engagement with one side of said pin member near the opposite end thereof. Said pin member is formed on one side near said opposite end thereof with a recess which is adapted to receive and releasably hold said intermediate por...

A tractor-trailer connector having an upper member mountable on a tongue portion of a trailer with a hitch engaging member pivotally mounted on a lower portion of the upper member, the hitch engaging member is pivotable about an axis generally aligned longitudinally with the trailer.

Safety pin with base-supported pin shaft and locking clasp having rigid wing members at opposite sides of the shaft point, the wing members including inwardly overhanging buttressed portions having spaced parallel flanges to form a guide slot for the shaft point, a spring strip biased upwardly against and bridging said portions and yielding to applied shaft pressure for movement of the shaft under the strip into locking position.

This invention is a locator pin. It has a mounting end portion and an integral head end portion, wherein the head end portion of the locator pin is a cylindrical form with oblong cross section the ends of the cross section being arcuate. The sides can be straight or curved. A machine for forming the head end portion of the pin has a base rigidly mountable. A housing is transversely movably mounted on the base. A pin mounting is on the housing. The machine in use rotates the pin mount simultaneou...
