M

Attached by a rivetor similar device I 2 passing I through theibase fi :near the 1 offset portion 6; is a U.-shaped bracket generally. designated I3 which is formedwofgflat material in theform indicated in Figural, and whose bight portion is traversed tion is secured to theifront face of the base 5 atthe place indicated. --.It is to be observed that a portion of the-bracket member Ill extends sufliciently forwardly'as indicated at l4 to'engage the upper edge of .the bight portion of the bracket I3 and thereby prevent rockingof'thebracket l3.

In eacho'f the arms of the bracket I3 is a horizontalslot l5 which "extends almost to the outer end of the arm. Below the outer end of each slot I5 is a small notch Iii-formed inthe lower edge of the arm. Slidablyand rotataloly mounted between the armsof the bracket I 3 is a hollow roller l1 having alongitudinal slot I 8 in one side for receiving the -chise'l end of the collapsible container l9. The roller-ll has a pin 20 at its left hand end whichis rotatable and slidable in the slot in the left hand arm of the bracket l3,'while akey member. 2| projects from the right hand end of the roller I1 and forms the right hand bearing .1 in the slot l 5 in the right hand arm of the bracket Figure 5 is a transverse vertical sectional view l3.

Means for pushing (the solid roller 23 rearwardlyagainst the roller l1 and pushing the roller I1 against therearendsofthe'slots l5 comprises helical springs .25, 26 which have their rear ends anchoredas indicated at 2 1;;28 to the outer sides oftherarms of the bracket l3, and have their front ends anchored in eyes'30 formed on the ends ofthe arms of a U-shaped rod 29 which has its long straight bightportion 3| removably inserted in'thenotcheslS in the lower edges of the arms .ofthebracket 31* The armsfof the, U-shaped rod :are: L-shaped and when therodis in position in the notches it, the L-shaped arms extend outside of and along the arms of the bracket l3 as particularly well shown in Figures 2 and 3. The foot portions 32 on the L-shaped arms have the eyes formed on their free'ends and to which the springs 25 and 26, respectively, are attached.

The foot portions bear forcibly against the pins.

24 of the idler roller 23 so as to push this roller rearwardly with sufficient force to produce the desired flattening of the tube as the tube is wound on the roller 11.

As the roller I1 is rotated by the key in a clockwise direction, as viewed in Figure 2, the chiseli a end of the collapsible tube I!) will be drawn between the rollers so that the tube 'will'be com' pressed and the contents thereof squeezed con;;;;

trollably from the threaded neck 33 oflthe tube, The mechanism I provide'for cooperating with the discharge end of the collapsible tube f unctions-;

to preserve the vertical and lateral alignment of the tube at all times, so that anevencollapsing of the tube is assured as well as smooth action end of the tube i9 comprises a bracket generally designated 34 which includes a vertical plate 35 which slidably engages the front face of the base 5, portions of the outeredges of the plate 35 being bent around the edges or the base 5so as'to secure the bracket 34 siidably'onthe m 5; V Upward projections from the plate 7 35 indicated by the numerals 31 also engage the front face of-the base 5-and steady the-bracket 34 thereon;

V The horizontal forwardly projecting portion 38 of the bracket 34 is narrower than the plate 35 and has a longitudinal opening 39 formed inwardly from its front edge which-is formed with angular sides 4|], 4| forming the inner end thereof and constituting two adjacent sides of a hexagonal figure. To the rear'of the opening 33' a narrow longitudinal slot 42 extends from the rear end of the plate 38 toan intermediate portion thereof and acts as a guide for a sliding projection '43 rising from the rear edge of the sliding gate 44 and the gate has intermediate lts'ends the hexagonal hole'45 with whichthe opening 39 in the plate 38 cooperatesto clamp the discharge neck of the collapsible tube. I I Two opposite-sides of the gate have the edgesthereof'bent upwardly and'dver the side edges of the plate 38 as indicated bythe numerals 45 and .46 so as to connect the gateflsslidably with the'plate 38 A lug flis cut out between the ends of the portions 45, 43 and remains onbent so as to project laterally from the side edges of the gate 44. Contractilehelical springs 48 are stretched from the. front face-oi the plat/e35 as'indicated at'49 and thecorrespondinglug'fl so as to pull the gate -44 normally toward the base 5, so that the gate 44 will'be urged into clamping engagement with the neck 33 or the container I! So'as to grip the same between the edges or the opening of the plate 38 and the edges oithe open.- ing of the gate 44, the neck 83being placed through the opening 39 andthe hole 45,'the hexagonal sides'of whicha'ssist in firm gripping of the tube neck, The projection 43 on the gate :44 being engaged in the slot lz-mrthe plate 38 aids the portions 45, 46, in preserving the desired alignment and free Working of the plate 38 and the gate 44.

The lower edge of the plate 35 is slotted at spaced points as indicated at 50 to form a tongue which is rolled to form the barrel 5| for containing a pivot pin 52 the ends of which extend from the ends of the barrel 5| into ears 53 formed on one end of a swinging closure generally desige hated-:54.- I r "The, swinging closure 54 'comprisesa narrow plate which has the spaced ears 53 formed onone end and has the opposite end downwardly directed as indicated at 55 to provide a finger grip. Near theiront end of the closure 54 and extending from the top surface thereof is a cylindrical formation 56 whose upper edge is cut off at an angle as indicated at 51, whereby a cup is formed for rece ving the open end oi the tube neck 33 and closing the same, when engaged therewith. Means for holding the closure 54 engaged with the open end of the tube'neck 33 comprises a spring bracket '58 which is securedas indicated at 59 tothe front face of the plate-flat the left hand side of the closure as shown in Figure 1. This spring bracket has an oilset-portion 60 with which is adapted to engage a lug 6| projecting from the corresponding side of the-clos'ure, when'the closure is in them) ward tube neck closing position. -The" swinging closure 54'is releasable from the bracket58 simply by drawing downwardly on the closure" in an obvious manner. 1 s i pulling th'egate 44 forwardly torelease the tube neck 33, there is provided a'depending portionfil which isformed by bending downwardly a; portion or the front end of the gate as shown in FiguresZand'l; Y

As the tube IS'is wound upon the roller I1 and between the roller l1 and the idler roller 23, the bracket 34 will correspondingly slide upwardly on the bas'e5while preserving the initial alignment of the tube. This-is especially desirablewhen the tube is almost exhausted, as it enables expelling from the tube practically all of the contents thereof. The spring pressed arrangement-of the rol1ers l1, 23 properly coacts with the chisel end of the tube I9 50 that the tube 18 cannot pass betweenthe rollers and wind-on the rollersll without having been properly compressed by the rollers."" 7 s Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that Ido not desire to limit the application of the invention thereto,=and any change or changesmaybe made in the materials in the structure and arrangement o'fthe parts,

within the spirit of the invention and the scopeoi the subjoined claims. d
