6 claim; l(o1. 5221-60) My invention relate'sto Atheclass of devices for pressing the wallsof'collapsible tubes intoV close contact for the purpose-of expressingr thel contents of said tubes, and an object of my invention, among others, is theV production of a device of this class that shall be simple in construction, thereby enabling'production at a minimum: cost and ensuring efficiency of the device in operation. Different formsof ejectors embodying my in# lo ventionV and in the construction and use of which the objects herein set out, as well as others, may be attained are illustrated in the accompanying drawing, in whichf1 Figure 1 is an end'view of my improved ejector the contents have been partially removed.

Figure 10 is a view in section through another modied form of the device, and Figure 11 is a similar view modification.
My improved device illustrated and described herein is of the same general character as that covered by my Patent No. 1,773,104, dated August 19, 1930, the present invention embodying different forms of the ejector which have developed in exploiting the device. In the accompanying drawing the numeral 12 (see Figs. 1 to 5) denotes the ends of the frame of one form of my improved ejector and 13 the base of said frame that connects said ends, these ends thereby constituting'a frame of U-shape when viewed from the front. 45 A slot 14 is cut through each end of the frame to front View of the ejector with the of still another receive the conical shaped ends 15 of the ejector rollers 16 which are rotatably mounted in said slots. In this form of the device the tapered ends "of the rollers, the width of the slots 14, and the 50 distance between the ends 12 are so proportioned that the rollers 16 may be separated sufficiently to receive the collapsed walls 17 of a collapsible tube 18, and as shown in Figures 1 to 5 of the drawing. The frame is preferably constructed of shown as applied to a collapsible tube from which metal having such resilient propertiesfthat some spring-action will existv in theends 12 the slots of which, acting in connection with the conical 1 shaped| ends of the rollers, will cause such rollers to be pressed with a resilient action toward each' other. In the use of the device the bottom end 19 having been inserted between the rollers the latter are rotated bymeans of the thumb and fingers to. roll the Vtube inwardly, the rollers beingpref-A erably knurled or otherwise roughened to` aid inv this operation. The ejector -may thusbe progressively advanced along the tube untilfthe con--l tents are completely-expelled therefrom. f Ity will thus be seen'thatthe ends 12 not only, serve to retain the rollers in resilientcontact ywith each other but they also serve to maintainthe alignment of the rollers.
Inthe form of the device shown in Figure 6 the', rollers are of different form although actingih much the same way asthe rollers just described. In this form offthe device a-supporting roll -20'has flanges 21 at its ends, and a compressing roll 22 is located between said iianges with its ends in close proximity thereto, said flanges serving as retainers to preserve the alignment of the two rollers. The flanges may be created in any desired manner, as shown herein interengaging` screw threads between the roller 20 and the flanges being employed. Annular grooves 23 are formed in the facing sides of the flanges to receive the ends of a compressing spring 24 preferably of bowed form, as shown in Figure 6, said spring having a support 25 preferably midway between its ends. The roll 22 is hollow and the spring extends through the roll, projecting at opposite ends thereof into the annular grooves 23, and as shown in Figure 6 ofthe drawing. The support 25 retains the spring in form to press the roller 22 into close contact with the roller 20 thereby exerting a yielding pressure upon the collapsed walls 17 of a tube held between the rollers.
In the form of the device illustrated in Figures 8 and 9 the rollers 26 and 27 are of tubular shape, each roller having an annular groove 28 formed near each end thereof, said grooves being for the purpose of receiving the ends of U-shaped springs 29, as shown in Figure 8 of the drawing, the ends of said springs having a compressing action whereby the two rollers are forced into contact to resiliently support the collapsed walls 17 of a tube between them.
In that form of the device shown in Figure 10 the rollers 30 and 31 are hollow as just beforedescribed and V-shaped retainers 32 are engaged With the Walls of the rollers, as shown in Figure 10, to retain the latter against separation. A spring 33 engaged at its opposite ends with one of the arms of each V-shaped retainer to draw the retainers toward each other and thereby hold the rollers in yielding contact with each other te resiliently clamp the collapsed Walls 17 of the tube between them.
In that form of the device shown in Figure 11 the rolls are of the same shape as shown in Figure 10 and V-shaped retainers 34 are employed.-
In this form of the device, however, an added spring 36 is employed to connect theA opposite arms of the retainers from that shown in Figure 10.
In accordance with the provisionsof the patent statutes I have described the principles of operation of my invention together Withthe'device which I now consider to represent the best embodiment thereof; but '.I 'de'sirelto haveit un'- derstood that the device shown is only'illustrative, and that the invention may be carried out by other means and applied to uses otherA than those aboveset'out.
I claim: n V
l. An ejector for the contents rof collapsible tubes, saidejector being mounted on and supported solely by the tube being emptied and including a pair of ejecting rolls and a U-shaped frame having slots in its opposite sides Within which are rotatably engaged the oppositejends of each of said rolls'ther'eby locating the `outer one of said rolls in the open side of said frame for access thereto of the ngersto rotate the roll.
2. An ejector for the contents of collapsible tubes, said eiector beingl mounted on and supported solely by the tube being emptied and in` cluding a pair of ejecting rolls peripherally accessible to the ngers for promoting their travel along a tube, the ends of said rolls being tapered, and a U-shaped frame having resilient end' parts alignment and to force them together.
