Abstract
Abstract A selective outlet pump for filling different types of masticapplying tools in which a three-way valve is mounted in the outlet of the pump for directing the mastic to issue from the desired outlet orifice. Different types of mastic-applying tools require different methods for filling the tools with mastic and this in turn requires specially designed outlet nozzles that can be used for this purpose. The three-way valve will deliver mastic to only one outlet at a time.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
218 words
A pump for filling mastic applying tools comprising; a pumping unit operable to pump mastic; a means for supporting said pumping unit in a container having mastic therein; a valve housing connected to said pumping unit; a rigid standard connected to said valve housing and extending downwardly therefrom on the outside of said mastic container and terminating in a foot portion, said standard having a downwardly extending first mastic conveying passage connected to said valve housing and terminating in an upwardly extending first outlet spaced from said foot portion, said first outlet provided with a gland adapted to receive a tubular nipple of a mastic applying tool inserted therein to form a liquid tight seal therebetween; said valve housing having a second and third mastic conveying passage each of which terminates in a different shaped outlet; a rotatable valve plug positioned in said valve housing aNd having an opening therein for communicating with said mastic conveying passages; an arcuate shaped handle connected to said plug and adapted to embrace a mastic applying tool and positioned above said gland so that when the arcuate handle is rotated so as to lie in a horizontal plane to receive and embrace the mastic applying tool, the opening in said plug places the pumping unit in communication with said first mastic-conveying passage;

A pump for filling mastic applying tools comprising; a pumping unit operable to pump mastic; a means for supporting said pumping unit in a container having mastic therein; a valve housing connected to said pumping unit; a rigid standard connected to said valve housing and extending downwardly therefrom on the outside of said mastic container and terminating in a foot portion, said standard having a downwardly extending first mastic conveying passage connected to said valve housing and terminating in an upwardly extending first outlet spaced from said foot portion, said first outlet provided with a gland adapted to receive a tubular nipple of a mastic applying tool inserted therein to form a liquid tight seal therebetween; said valve housing having a second and third mastic conveying passage each of which terminates in a different shaped outlet; a rotatable valve plug positioned in said valve housing aNd having an opening therein for communicating with said mastic conveying passages; an arcuate shaped handle connected to said plug and adapted to embrace a mastic applying tool and positioned above said gland so that when the arcuate handle is rotated so as to lie in a horizontal plane to receive and embrace the mastic applying tool, the opening in said plug places the pumping unit in communication with said first mastic-conveying passage;
Claim 3
Dependent Claim
56 words
The combination as set forth in claim 1 wherein said second mastic conveying passage terminates in a cylindrical shaped outlet that is disposed above said gland so that a rotation of said handle into a position for registering said plug opening with said second passage will cut off any flow of mastic to said first passage.
Claim 4
Dependent Claim
76 words
The combination as set forth in claim 1: and in which a. said valve housing has a third opening communicating with a third mastic-conveying passage that terminates in an outlet nozzle that is oval-shaped so that a rotation of said handle into a position for registering said plug opening with said third valve housing opening, the plug will cut off the other two valve housing openings and permit mastic to flow only through said third passage.
Claim 5
Dependent Claim
95 words
The combination as set forth in claim 3: and in which a. the face of said valve plug is exposed and is provided with a mark indicating the position of the mastic outlet opening in said valve plug; b. said valve housing having markings indicating the three postions into which said valve plug can be rotated so that when the mark on said valve plug registers with any one of the three markings on the valve housing, the operator will know which one of the three mastic-conveying passages is in registration with the plug opening.
