Klamath Falls, Oreg.
Application December 19, 1947, Serial No. 792,755
3 Claims. Cl. 222102) This invention relatesto new and useful improvements in dispensers and the primary object of the present invention is to provide a dispenser including novel and improved means for supporting and squeezing a collapsible tube in order to eject the paste contained therein.
Another important object of the present invention is to provide a dispenser for collapsible tubes such as tubes of tooth paste, shaving cream, soap and the like, including a pair of rotatable gripping rollers and novel and improved means for adjusting one of said rollers relative to said other roller, whereby tubes of various sizes may be applied between the said rollers.
A further object of the present invention is to provide a dispenser including means for guiding the closed end portion of a tube to a discharge opening.
A still further aim of the present invention is to provide a dispenser for collapsible tubes that is small and compact in structure, simple and practical in construction, strong and reliable in use, neat and attractive in appearance, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a front elevational view of the dispenser constructed in accordance with the present invention, and showing the same in use;
Figure 2 is a longitudinal vertical sectional view taken substantially on the plane of broken section line 2-2 of Figure 1;
Figure 3 is a transverse vertical sectional view taken substantially on the plane of section line 3-3 of Figure 2; and,
Figure 4 is a longitudinal horizontal sectional view taken substantially on the plane of section line 4-4 of Figure. 2.
Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral I0 represents the housing used in conjunction with the present invention generally, comprising a pair of spaced side walls I2, an arcuate upper wall [4, an arcuate lower wall [6, and a rounded end wall IS. The upper wall l4 and lower wall l6 are turned outwardly adjacent the open end 20 of the housing to provide an attaching flange 22 that receive counter sunken fasteners 24 for removably securing the housing relative to a supporting structure such as a wall surface or the like 26'.
Opposed longitudinal guide slots or grooves 28 are provided in the inner faces of the side walls l2 and slidably engage the side'edges of a pair of inner arms 30 that are connected at their outer ends by integral cross bars 32, and the side edges of a pair of spaced parallel outer arms 34, that are connected at their outer ends by an integral cross bar 36.
The adjacent inner ends of the arms 30 and 34 are provided with notches or recesses 38 and 46 that rotatably support a driven shaft 42 and a drive shaft 44. Fixed on the driven shaft 42, is a corrugated or toothed driven roller 46 that opposes a complementary corrugated drive roller 48 that is fixed on the drive shaft 44, These rollers 46 and 48 oppose, a tube receiving opening 50 provided in the lower wall 16 of the housing l8.
. Receivably engaging an internally threaded aperture 52 provided in the end wall 18, that aligns the groove 28, is an externally threaded adjusting rod 54, the inner end 56 of which frictionally engages the cross bar 36 for selective adjustment of the drive roller relative to the driven roller. A knurled surface finger gripping knob 58 fixedly carried by the outer end 60 of the rod 54, facilitates the convenient adjustment of the rod within the aperture 52. One end 62 of the drive shaft 42 projects outwardly from one of the side Walls l2, and is slidably mounted in a substantially vertical notch or slot 64- provided in said side wall. A knurled surface finger receiving knob 66 is fixedly carried by the end 62, for rotating the drive shaft.
The inner face of the upper wall I4 is provided with an arcuately notched portion 68 that opposes the driven roller 46. An arcuate resilient guide strip 18 has one end 12 fixed in said notch portion 68, and the opposite end 14 of said guide strip frictionally engages a transverse recess 16 provided in the lower wall I6, adjacent the opening 50.
In practical use of the device, the stiff metal edge or closed end 18 of a collapsible tube is extended between the rollers 46 and 48, and the rod 54 adjusted so that by rotating the roller 48 in one direction, the roller 46 will rotate in an opposite direction and the end 18 of the tube will be forced intothe housing, and the contents 82 in the tube 80 will be ejected from the nipple 84 of the tube to a brush or the like 86 disposed therebeneath. Upon continued rotation of the drive roller, the end 18 of the tube 80 will frictionally engage the guide strip H! to follow the contour of said guide strip loosely about the driven roller 46, whereby when the contents of the tube are completely removed, the rod 54 may be loosened so that the end 18 of the tube 80 may be pulled downwardly to remove the tube 89 from the housing 10.
In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though there is herein shown and described a preferred embodiment of theJinvention the'same is susceptible to certain changes fully comprehended by the spirit of .the invention as herein described and the scope of the appended claims.
Having described the'inventionfwhat'is claimed as new is:
-1. A dispenser for collapsible tub'e's comprising a housing open at one end and having a lower wall, an attaching flange carried by the open end of said housing, a'tube receiving opening provided in the lower wall of-said housing, a slidable roller support mounted with said housing, a driven shaft journaled for rotation on said support, a toothed driven roller fixed on said driven shaft, a further support slidably mounted with said housing, a-drive-shaf-t journal'ed for rotationon said further support, a toothed drive roller fixed on said drive shaft andopposing said driven'roller, means for selectively adjusting said drive roller relative to-said driven roller, said slidable roller support including a substantially U- shaped member having spaced leg portions and a web portion joining said leg portions-opposed longitudinal recesses provided inthe inner walls of said housing slidably receiving the leg portions of said 'U-shaped 'member, an arcuate spring member mounted in said housing and loosely embracing the driven roller, said housing including an upper wall, a transverse recess provided in the inner face of the upper wall above the driving roller and receiving one-end of said spring member, and a further transverse recess provided in the inner face-of said lower wall adjacent the tube receiving opening and receiving the remaining end of said spring member, said spring member closing the open end of said housing and adapted to guide the closed end of a tube about the driven roller and back through the tube receiving opening.
2. A dispenser for collapsible tubes comprising a housing including a pair of side walls, an upper wall and a lower wall, said housing being open at one end, an opening provided in the lower wall of said housing, opposed longitudinal recesses provided in the inner faces of said side walls and having entrances at the open end of said "housing, a pair of substantially U-shaped supports slidably received in said recesses, a driven roller supported solely by one of said supports, a driving roller supported solely by the remaining of said supports, means threaded on the housing and connected to said last named support for adjusting said supports relative to each other, said supports being removable 'from said housing through the open end thereof, an arcuate guide member mounted in said housing and loosely embracing the driven shaft :for guiding the closed end of a tube about the driven roller and toward the opening in said bottom wall and for closing the open end of said housing, and means for rotating said driving roller.
3. The combination of claim 1 wherein said spring member extends between the leg portions of said U-shaped member and between the web portion of said U-shaped member and said driven roller to limit sliding movement of said U- shaped member.
