Grip for a swivel hose coupling

A grease gun is provided comprising a body having a reservoir bore with a plurality of grooves; a grease reservoir is in communication with the reservoir bore and has a reservoir groove on an outside surface of the reservoir. A retention fastener is received by a groove and is in operational engagement with the reservoir groove to removably retain the reservoir. The retention fastener may be connected to a fastener bracket via an aperture. The bracket is connected to a push-button via a connection mechanism. The grease reservoir may be removed or mounted to the connection aperture by exerting force on the button which transfers the force to the bracket via the connection mechanism. The force causes movement of the bracket along the aperture which deforms the retention fastener to allow the grease reservoir to be mounted/removed.

Push-button grease gun barrel and method of use

A grease gun is provided comprises a body having a reservoir connection aperture with an inner portion, an outer portion and a plurality of concentric grooves positioned along the inner portion, a grease reservoir is in communication with the reservoir connection aperture and has a groove in a portion of an outside surface of the grease reservoir, and a retention fastener is received by at least one concentric groove and is in operational engagement with the grease reservoir groove to removably retain the grease reservoir. A method of mounting a barrel to a grease gun is also provided.

Quick connect grease gun barrel and method of use

A portable grease gun with the capability of being attached to either a grease containing barrel or a hose carrying grease from a grease supply container. An adapter may be mounted to the barrel mounting in place of a barrel to couple the grease gun to a hose connected to a grease supply container remote from the grease gun. Alternating plug may be mounted in the barrel mounting and a pumped grease supply coupled to the resupply port on the grease gun. The grease gun includes an output valve which restrains passage of grease at pressure below 30 psi.

Grease gun with remote-feed adapter

A portable grease gun with the capability of being attached to either a grease containing barrel or a hose carrying grease from a grease supply container. An adapter may be mounted to the barrel mounting in place of a barrel to couple the grease gun to a hose connected to a grease supply container remote from the grease gun. The grease gun includes an output valve which restrains passage of grease at pressure below 30 psi.

A portable grease gun with a dual pressure output capability which can be selectively changed by the user with little effort. The larger diameter plunger is slidable within a plunger retainer. The larger diameter plunger has a bore through them in which a smaller diameter plunger is slidable. The smaller diameter plunger moves when an actuating lever is operated to compress grease in the grease gun. The larger diameter plunger may be adjusted to remain static during operation of the actuating lever or it may be adjusted to move during all or part of the compression stroke of the actuating lever. A high pressure can be generated by movement of the smaller diameter plunger alone, or a high flow volume can be generated by movement of the smaller and larger diameter plungers in unison.

Two stage grease gun

A portable grease gun with a dual pressure output capability which can be selectively changed by the user with little effort. A larger diameter plunger is longitudinally coupled to an extension. The larger diameter plunger and its extension are variable in length by manual rotation of the extension relative to the larger diameter plunger. The larger diameter plunger is slidable within a plunger retainer over a limited range and is not free to rotate within the plunger retainer. The larger diameter plunger and the plunger extension have aligned bores through them in which a smaller diameter plunger is slidable. The smaller diameter plunger moves when an actuating lever is operated to compress grease in the grease gun. The larger diameter plunger may be adjusted to remain static during operation of the actuating lever or it may be adjusted to move during all or part of the compression stroke of the actuating lever.
