    A.D. N0'20,077 1902 »< Date of Application, 18th Sept, 1902—Accepted, 22nd Jan., 1908 COMPLETE SPECIFICATION. Improvements In Machines for Making Pill Boxes and the like * 5 15 o ) X, Franz Fettbacic, of Andrertensche Wiese 20, Hanover, in the Empire of Germany, Manufacturer, do hereby declare the nature of this invention and in what manner the same is to be performed to he particularly described and ascertained in and by the following statement : The present invention relates to improvements in the machines described in the Specification of British Patent No. 19109 dated 26th September 1901. The present invention relates more particularly to improved arrangements for the supply or feed of the strips and for holding the strips on the spindle by means of an improved holder and for a device for holding the end of the 10 cut strip, also to improved means for lifting and placing in position the bottom of the box and folding over the edge of the covering strip. The various new parts are shown in the annexed drawings and those already referred to in Patent No. 19109 of 1901 are indicated by the same reference letters and numerals as in the said patent. Fig. 1 is a vertical section of the new strip feed device, Fig. 2 is a plan view thereof, Fig. 3 is a cross section and plan viev of an essential part of ihe device on a larger scale. Figs. 4 and 5 are vertical sections of the strip holder in the working and resting positions respectively. Fig. 6 is a cross section on the line A—B of Fig. 5 seen in the direction of the arrow. Fig. 7 is a side view partly in section of the arrangement for holding down the cut end of the strip. Figs. 8 and 9 are detail views of two different parts shown in Fig. 7. Fig. 10 shows the arrangement for lifting and placing in position the bottom and lid of the box, Fig. 11 is a section on the line C—D of Fig. 10. Figs. 12 and 10 illustrate two different working positions of a device for folding over the edge of the covering strip, and Figs. 14 and 15 represent another form of' folding device also in two different working positions. The new strip feed device shown in Figs. 1 to 3 is an improvement over that of Patent 19169/01 by reason of one of the cheeks or grippers 7 8, being formed by a fiat spring 8. The strip is guided between the two parts 7 and 8 as before, the spring 8 bearing on the non-adhesive side of the strip. The pressure of the spring 8 35 is adjustable by means of the screw c, by which the spring is fastened to the end of the gripper 7. The adhesive side of the strip abuts against a special slide surface f (see Fig. 3). The friction to which the strip is subjected during its passage between slide surface f and the end of the spring 8 keeps the strip tensioned on its way to the spindle. The above described features of the feed device have the following important advantages. The tension of the spring 8 is exactly regulatable and the spring can be easily removed and interchanged or rendered inoperative by turning it aside, [Pries 8/7.] *25 30 40
