. This invention relates to dispensing apa". These arms have rollers a mounted beparatus of the type adapted for dispensing tween their ends and are formed with downrneasured quantities of a cream, such as shavwardly extendingi shoulders at Extending ing cream, tooth paste, etc. Existing forms upwardly from the faces of the shoulders a, 'of these devices have included receptacles for are guide rods a7 upon whichA slides a cross- 55 holding the tube and, in some instances, de'- piece b.

It will be apparent that changes in the design and arrangement of parts may be'made 10 without departing from the scope of this invention and the atter is not to be limited, save as defined in the appended claims.

I claim as my invention: 1. In a dispensing apparatus for a tube of a fluid substance, a support, a key carried by the support for winding the end of the tube manually, squeezer rolls, means to mount the tube between the rolls, shoulders on the support, springs carried by the shoulders, and blocks carried by the key against which the .springs en age.

2. In a 'spensing apparatus fora 'tube of a fluid substance, a support, a key carried by i the support for winding the end of the tube manually, squeezer rolls, means for exerting a pressure on the key, a casing carried by the tu e, means to mount the casing slidably in the sup ort, a plunger in the casing, and a y spring or` normally retracting the plunger. 3. In a dispensing apparatus for a tube of a fluid substance, a support, a key carried by the support for winding the end of the tube manua squeezer rolls, means for exerting a ressure on the key, a casing carried by the tu means to mount the casing slidably in the support, a hollow plunger in the casing, apertures in the lcasing and plunger, and a spring for normally retracting the plunger.
