It will be apparent that this action serves to dispense a predetermined quantity of the product from the port 60. The piston is moved through the action of a spring detent 55 carried by the handle and operating on the ratchet wheel 28 to rotate the tube forwardly with the handle and in a direction to move the piston downwardly. A spring detent 58 carried on the end wall ll cooperates with the ratchet wheel 26 to prevent return rotation of the tube. The valve and rod are lifted by means of a cam 66 carried by a nut 64 threaded onto the top end of the rod. The other end of this bracket extends downwardly through a hole 65 in the end Wall I l whereby to prevent rotation of the bracket.

The dispenser may be supported on a wall 68 by any suitable means, such as a bracket 'Hl spot welded to the body member at 12 and provided with holding screws 14 securing it to the wall.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is,

1. A dispenser for soap or the like, comprising a body having an annular portion adapted to receive the open end of a container, means for removably securing the container to said portion whereby freely to suspend the container therefrom, a threaded tube suspended from the body through said annular portion, a piston threaded onto the tube and adapted to engage the interior wall of the container, a rod extending through the tube and having a valve on its free end for cooperating with an exit in the container, a handle carried by the body and mounted for free pivotal movement on the tube, a ratchet wheel fixed to the tube, a detent carried by the handle and cooperating with the ratchet wheel to rotate the tube, and means including a cam carried by the handle for raising the rod and valve upon pivotal movement of the handle.

2. A dispenser for soap or the like, comprising a body having an annular portion adapted to receive the open end of a container, means for removably securing the container to said portion whereby freely to suspend the container therefrom, a threaded tube suspended from the body through said annular portion, 'a piston threaded onto the tube and adapted to engage the interior wall of the container, a rod extending through the tube and having a valve on its free end for cooperating with an exit in the container, a handle carried by and having its inner portion housed within the body, the free end of the handle extending outwardly through a slot in the body wall, a spring normally holding the handle at one end of the slot, means for raising the rod and Valve upon movement of the handle against the action of the spring, means causing rotation of the tube and forward movement of the piston upon such movement of the handle, and means preventing reverse rotation of the tube upon return movement of the handle.

3. A dispenser for soap or the like, comprising a cap embodying an end wall and a flanged peripheral portion, an annular member having its top end fitting over and secured to said peripheral portion of the cap, a single walled cylindrical container having its top end open and fitted in overlapping relation on the bottom end of the member, means detachably securing the container to the member in such position whereby the container is suspended freely therefrom, a tube carried by the end wall and extending downwardly through the annular member, a piston on the tube for engaging the interior wall of the container, a rod within the tube and having a valve on its free end cooperating with a restricted exit in the container wall, and means including a handle carried by the cap and extending outwardly therefrom for raising the rod and valve and moving the piston longitudinally along the tube.

4. The dispenser defined in claim 3 plus a cover housing the cap and parts carried thereby and having an edge portion removably fitting over the peripheral portion of the cap and substantially in abutting relation with the annular member.

5. The dispenser defined in claim 3 wherein the first-named means includes a spring ring within the interior of the annular member and having pins thereon extending outwardly through said member and engaging within openings through the container wall.

6. In combination, a single walled cylindrical container having an open top end and a conical bottom end with a centrally disposed exit port therethrough, a body member, means engaging the top end of the container freely and removably suspending the container from the body member, a threaded tube carried by the body member and disposed centrally within the container, a rod within the tube and having a valve at its free end cooperating with said port, a piston fitting within the container and threaded to the tube, means including a handle freely rotatable on the tube for raising the rod and valve upon movement of the handle and ratchet means for rotating the tube upon movement of the handle in one direction.

'7. The combination set forth in claim 6 wherein the valve normally closes the port when the handle is in its normal position, and a spring normally rotating the handle about the longitudinal axis of the tube to such position.
