Adhesive dispensing tool for use with a rotary power tool
First Claim
1. An adhesive dispensing tool adapted for use with a detachable rotary power tool, comprising;
- a receptacle adapted to hold a tube of adhesive material in a dispensing position, the receptacle having a dispensing end and a drive receiving end;
an expandable and retractable drive mechanism having a variable length comprising a first threaded elongate drive member having a chuckable end selectively connectable to the rotary power tool and a second threaded elongate drive member carrying a drive plate into the drive receiving end of the receptacle, the first drive member juxtaposed to second drive member with threads of the second threaded drive member interfitting with the threads of the first drive member, the second drive member being linearly translatable by rotation of the first drive member; and
a drive housing containing the drive mechanism therein, the drive housing having a first end connected to the drive receiving end of the receptacle and a second end adapted to selectively receive the rotary power tool, the distance between the first and second ends being fixed during expansion and retraction of the drive mechanism.

Abstract
A caulking gun or adhesive dispensing tool is driven by an expandable drive mechanism. The drive mechanism comprises a threaded shaft interfitting with the threaded inner surface of a receiving sleeve. The sleeve carries a pusher plate into a caulk receptacle for engaging a tube of adhesive material. The shaft is attachable to the chuck of a common drill. Rotation of the shaft linearly translates the sleeve and hence the pusher plate into the caulk receptacle. A drive housing interposed between a drill and the caulk receptacle generally houses the drive mechanism and extends the length of the adhesive dispensing tool to provide for easier manipulation thereof. The adhesive dispensing tool may include a handle and a pair of wheels for easier manipulation of the tool.

10. An adhesive dispensing tool adapted to be used with a detachable rotary power tool that has a chuck for gripping a shaft, comprising:
-
a receptacle adapted to hold a tube of adhesive material in a dispensing position, the receptacle having a dispensing end and a drive receiving end, a housing having a first end connected to the drive receiving end of the receptacle and a second end adapted to selectively receive the rotary power tool the second end being fixed relative to the receptacle; an extendible and retractable drive mechanism contained in the housing, the drive mechanism comprising a drive sleeve having a threaded inside surface and a threaded drive shaft interfitted with the threads of the drive sleeve, the drive mechanism having a chuckable end adapted to connect the chuck of the rotary power tool and a drive end carrying a drive plate into the drive receiving end of the receptacle, the distance between the chuckable end and the drive end being variable, whereby rotation applied to the chuckable end linearly drives the drive plate and the distance between the dispensing end and second end of the housing being fixed during expansion and retraction of the drive mechanism. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. An adhesive dispensing tool adapted to use a detachable rotary power tool that has a chuck for gripping a shaft, the adhesive dispensing tool comprising:
-
a receptacle for holding a tube of adhesive material in a dispensing position, the receptacle having a dispensing end and a drive receiving end, a cylindrical housing having a first end connectable with the drive receiving end of the receptacle and a second end adapted to receive the rotary power tool, the housing defining an access orifice near the second end of the drive housing for permitting access to the chuck of the rotary power tool the second end being fixed relative to the receptacle, the housing defining a slot having a length that runs along the axial axis of the cylindrical housing; means for mounting the rotary power tool to the second end of the housing; an elongate drive shaft housed inside the housing and having a chuckable end for selective connection to the chuck of the rotary power tool to receive rotary movement therefrom, the drive shaft being threaded; a elongate drive sleeve carrying a drive plate that extends into the drive receiving end of the receptacle for engaging a tube of adhesive material, the inside surface of the drive sleeve being threaded and interfitted with the threads of the drive shaft whereby rotation of the drive shaft translates the drive sleeve in a linear fashion, the drive sleeve including a finger extending radially outward therefrom, the finger fitting through the slot of the housing for preventing rotation of the sleeve and indicating the position of the sleeve, the combination of the drive sleeve and the drive shaft providing an extendible and retractable drive mechanism having a variable length, the distance between the dispensing end and second end being fixed during expansion and retraction of the drive mechanism. - View Dependent Claims (19, 20)
