SQUEEZER ron COLLAIBSIBLE TUBES.

To allwhpm it may concern Be it known that I THoMAs HnMAnTIrI, J

a citizen ofthe United States, residing at C- lumbus, inthe county ofFranklin and State of Ohio, have invented certain new anduseful Improvementsin Squeezers for Collapsible Tubes; andI do declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art. to which it appertains to make and use the same.

This invention relates tosqueezers for collapsible tubes, andmore specifically to an improved device for expressing the contents,

such as shaving cream, for'instance, froma' collapsible tube.

One object of this invention is to provide a device of this character which consists of ex ceedin 'ly few and simple parts which are securec together without the use of bolts,

rivets, solder or any fastening means other,

than the inherent elements of the essential supporting and working partsof the device,

thereby minimizing the cost of. manufacture and maintenance while. providing a structure that is very easily and conveniently operated, andv which 'presents an unusually pleasing appearance.

Another objectis to provide'a device of this, character in which a single pressure roller coacts with the shelf. or table to squeeze thetube, thereby eliminating the usual-see ond roller, at the sameftime providing an exceedingly effective support, for holding the mouth of the tube in" an elevated position,

the roller being spring-pressed towardthe' table to compensate for different thicknesses of each collapsible tube.

Other objects and advantages will be pointed out or implied in the following detailsof description, in connection with the accompanying drawings in which proved device.

receive the shanks 5 of a pair of journal.

bearings 6, A pressureroller 7 is journaled in these bearings and a hand-wheel .8 is se-' cured to one end'of the roller 7 and is manu ally operable for turning the roller. roller 7 axially parallel groove 9 in which the Hat end E o'fthe'collapsible T tube is insertable',

A pair ofthumb screws 11 have threaded engagement with the interior of the hollow shanks 5, and. a pair ofhelical springs 12 surround the shanks 5 and have their upper ends seated in countersunk portions of the openings 4:. Each of the thumb screws preferably comprises a knurled disk 13 and. a substantially flat finger piece 14, the former being convenient for affecting adjustments whenthe screws 11 work with relative ease,

and also constituting spring seats against which the outer or lower ends of the springs 12 press for the purpose of yieldingly holding'theroller 17 in such close proximity to the table 3 as to readily coact with the'l'atter for squeezing and flattening the tubes. The table 3 is preferably formed with a concaved and polished depression 15 which serves as a guide for the user in placinglthe tube between the table 3 and roller 7, also preventing the, tube from winding helically on the roller 7 and. coming into co'ntactwith the journal bearing 6. v I p The table 3 is apertured and screw-threaded at 16, and the upper screw-threadedend I r v of a standard 17 is fitted in this central- Figure 1 is a front elevation of my 1111- aperture andcoacts with a base or disk 18 for supporting the table 3 in spaced relation I The. is provided with a longitudinalor above a table or shelf onwhich the base 18 is intended to rest, and thisbase is provided with screw holes, one ofwhich is illustrated at 19, so that the unitary device may be secured in any desired convenient position; It should be understood that the base'lS can "be securedjto a vertical surface if desired, so that the mouth of the paste tube is elevated to a still greater extent than it is shown to be in Figs. 2 and 4, in which case, however, the brush support 2, being of wire, can be bent to extend at right angles to its present position. i

In operating the device, the slot or groove 9 is turned substantially at right anglestothe position indicated in Fig. 4, the fiat end portion 10 of the tube is inserted therein, and the hand-wheel 8 is turned in the dlrection of the arrow in Fig. 4, thereby bending the flat end portion of the tube and pullin 7 it through the space between the roller I and plate or table 3. The flat end 10 is substantially twice as thick, in practice, as the adjacent flattened portion, and thesprings 12 yield to permit this relatively thick portion to pass through said space. The cap of the tube is removed, of=course, to permit the shaving cream or other contents of the tube to be expressed through its mouth, and

when a sufficient quantity has been obtained from the tube, its cap is replaced, and the pressure of the springs 12 maintains suflicient friction between the tube and the plate 3 to prevent accidental retrograde movement of the roller 7. After-a considerable quantity of the material has been expressed from the tube, and the roller 7 has turned a complete revolution, the flattened portion of the tube begins to wind upon itself, thereby thickening the material which must be passed through the space between the plate 3 and roller 7, and the springs 12 compensate for this additional thickness. In view of the fact that some collapsible tubes are of thicker and stiffer material than others, and of the fact that some pasty or creamy contents of such tubes are thicker or more nearly solid than others, it is necessary to regular the tension of the springs 12, and

the thumb screws 11 serve to effect this function. v

The screw-threaded engagement of the standard 17 with the plate or table 3 enables the latter to be quickly and easily removed from the standard when desirable,an d moreover in view, of the fact that this single standard is connected to the plate 3 at a' point between the apertures 4, this provides unobstructed spaces into which the thumb screws 11 extend, so that thereis no interference with the'hand of the user in obtaining quick and easy access to the thumb screws.

Although I have described this embodiment of my invention-very specifically it is not intended to limit this invention to the exact details of construction and arrangement as. described and illustrated, but changes may be made within the scope of the inventive ideas as implied and claimed. What I claim as my invention'is: 1. In a device for compressing and forcing the entire contents from a collapsible tube, a support including a horizontal plate provided with a substantially flat upper face and with oppositely disposed apertures, bearing blocks including hollow internally screw-threaded shanks extending through said apertures, headed adjusting screws threaded in said shanks, coiled springs surrounding said'screws and shanks between the plate and heads of the screws, permitting yielding of the bearing blocks, a combined pressure and feed roller carried by said bearing blocks,- means for connecting the tubelto the roller, and means for imparting rotation to said roller.

2. In a devicefor expressing the contents of a collapsible tube, a support including a table having a flatupper face'with a transversely extending guide groove formedtherein, said groove merging at its inner end into the fiat face of the table and being curved to conform to the tube which rests therein, and. a .yieldably .mounted combined pressure and feed roller carried by the table. I 3. In a device'for compressing and forcing the entire contents from a collapsible tube, a base, a standard rising therefrom, a horizontally disposed substantially rectangular plate secured to the upper end of said standard, said platehaving a flat upper-face and being provided with a centrally disposed transversely extending guide groove which is of a greater depth at its outer end and 'merges atits inner end into the flat face of said plate, said groove being curved to conform to the shape ofthe tube which rests therein, said plate being also provided adj acent its opposite ends and in its under faces with sockets and communicating openings which extend vertically therethrough, bearing blocks including hollow internally screwthreaded shanks, the latter extending through said openings and sockets, headed adjusting screws co-operative with the screw-threads of said shanks, coiled springs surrounding said screws and shanks, bearing at one end against the heads on said screws and being disposed at the opposite ends in said sockets and resting against the inner ends of the latter, permitting yielding of the bearing blocks, a combined pressure and feed rollerincluding reduced'ends constiblocks including spring means under said table and acting on said shanks for moving said bearing blocks downwardly, a combined pressure and feeding roller including reduced ends journaled in said bearing blocks, said roller being equipped with means to permit connection of the closed end of a collapsible tube herewith one of the refor imparting roto, and means connected duced ends of the roller tation to the latter.

In testimony whereof I have hereunto set my hand. Y
