Abstract: 23,698. Thompson, W. P., [Hesser, F.]. Oct. 14. Paper bags.-Paper cases, bags, boxes, &c. Z, Fig. 12, are inserted into similarlyshaped tin - foil casings Z<1>, and a label Z<2> is stuck upon such casing, the whole forming a packet specially suitable for cocoa powder. The paper case is first placed upon a core, from which it is pushed into a box C by a plunger acting in conjunction with the plunger a. The box C then rises to a position opposite to a second plunger, which pushes the paper case into a tin-foil casing placed in one of the frames d of a wheel D. This wheel is rotated, through a quarter of a revolution at a time, by pins d' engaging with a swinging fork c" on a vertically-reciprocating rod c. A brake lever D<3> is pressed upon a disc on the wheel by a spring D<4>, and a sliding carriage F has a fork f to engage one of the frames d after each movement and hold it in position. The double bags are ejected from the frames d into the fork G by pins on a vertically-reciprocating carriage H, and this fork is then moved automatically on its guide g until the bag is directly over a second for J, travelling on a circular track J<2>. The bags are transferred from one fork to the other by an ejector K, and the fork J is then turned through a right-angle by an arm J' and lever connections. An elbow piece M then takes it off the fork J, and by means of a rod M' turns it into a vertical position beneath the plunger L, the bag being held against the elbow piece by an air pump connected to it by the pipe M<2>. The plunger is in four parts l, which are moved outwards radially by a cam plate on the rod O<2> to hold the bag, so that in its succeeding upward movement the plunger carries the bag with it. The cross-piece 0 of the plunger is suspended in a frame P from a counterbalanced lever P<1>, and is operated by a rod connecting the lever with a cam disc on the shaft E<2>. The labels to be gummed and applied are piled in a receptacle Q, and are fed upwards by a plunger Q<1> operated by a rack bar Q<2> and ratchet mechanism Q<3>. The gum is supplied to a stamp R from the reservoir S<1> by a roller S, and transferred from it to the uppermost label, the stamp R having for this purpose a horizontal movement on the bar R<1> and a vertical movement on the bar R'. The former movement is imparted to it by rods r, r<1>, r<2> from an eccentric 14, and the latter by a lever R<5> and connecting- rod from an eccentric on the shaft E<2>. When the stamp R is raised, it takes the uppermost label with it by adhesion, and then two rules T pass underneath the label Z' and grippers seize its ends to strip it from the stamp. The rules then slide back and bring the label beneath the plunger L and over an opening closed by spring flaps V. The plunger descends and presses the bag upon the label and between the flaps, the labelling being finished at the sides of the bag by horizontallymoving jaws W. Finally, the parts l of the plunger close together, the jaws W separate, and the finished packet falls into the collecting channel X in order to pass into a receiving-box, from which it may be removed for the purpose of being filled &c. The various motions of the different parts of the machine are obtained by means of levers and links from cams on a series of shafts E<1>, E<2>, E<3>.
