Assembly and method of mounting a liquid delivery device utilizing expanding bushing
First Claim
1. A mounting assembly for completely mounting a liquid delivery device through a mounting hole of the top of a support surface solely by insertion from the top of the support surface comprising;
- a flanged expandable bushing arranged to be inserted through the mounting hole from the top of the support surface for mounting a liquid delivery device, said expandable bushing having a lower skirt extending below the lower surface of the support member, said skirt having a plurality of expandable members, said expandable bushing further having a threaded central circular bore, a hollow expansion sleeve being moveably received in said threaded bore, said expansion sleeve having a threaded exterior surface for engaging said threaded bore, said expansion sleeve being moveable relative to said expanding bushing to urge said expandable members outward to assume a diameter greater than the size of the mounting hole for mounting of the flanged bushing beneath the support surface for securement to the support member, and means for rotating said expansion sleeve relative to said flanged bushing to cause said movement of said expansion sleeve relative to said flanged expanding bushing.

Abstract
A flanged bushing top portion is applied to a sink or counter surface over a mounting hole with a skirt portion descending from the top portion of the flanged bushing in to the mounting hole. A tapered expansion sleeve is threaded into the skirt portion of the flanged bushing. As the tapered expansion sleeve is threaded upwards into the tapered skirt portion, the skirt expands and pressed against the inside diameter of the sink mounting hole thereby securing the flanged bushing to the sink surface. A faucet valve assembly, soap/lotion dispenser, or water dispenser is lowered into the bores of the flanged bushing and the expansion sleeve, and the valve'"'"'s escutcheon collar is secured to the top of the flanged bushing by means of a lock down collar which is threaded onto the exterior threads of the flange of the flanged bushing. This secures the valve assembly, soap/lotion dispenser, or water dispenser to the flanged bushing and consequently to the sink. This same method is utilized to attach the faucet spout securely to the sink.

14. A method of mounting a liquid delivery device having a downwardly descending hose on a bushing inserted downward through the mounting holes of a support surface having upper and lower surfaces comprising the steps of
inserting a flanged bushing having a lower expandable skirt and a threaded central bore having a truncated conical configuration through the mounting hole of the support member, inserting an exteriorly threaded expansion sleeve into threaded engagement with said threaded central bore of said flanged bushing, attaching a locking collar on said flanged bushing to lock said bushing to the top of the upper surface, inserting a tool into said threaded bore of said bushing into engagement with said expansion sleeve, and rotating said expansion sleeve relative to said threaded central bore to cause movement of said expansion sleeve and wedge said expandable skirt outward to a diameter greater that the diameter of the mounting hole for the sole mounting of said flanged bushing.
