The lower end of the plun- Motion is imparted to the driving-gear of ger-rod d carries two pivoted levers g, each the machine either by the hand-wheel A or bearing rollers fand t' at their upper-and by suitable power pulley or gearing, and from lower ends. When the plungerb has reached 95 the main shaft B rotary motion'is transmitted the bottom of the mold Fand the rod d proby bevel gear-wheels C- and D to the gearingceeds farther down,by compressing the spring wheel q, Figs. a and 5, which through the e the rollers f will bear against the'inclin'ed medium of links m n o and connecting-rod guide-,surface h of the frame, whereby the p imparts intermittent rotary motion at regnlower arms of the levers g and the rollers 'i roo lar intervals to the main work-table at, supare forced inwardly and engage the sliding 5o ported upon the frame 17. The said workblocks k, pushing the same toward the mold table carries four sets of molds and folding F, thereby closing the ends of the mold withmeans, each set beinga counterpart of the in the wrapper, and when this has been accomplished the rod d commences to retrace its course. I'Vhen the lower side of the plunger b reached the bottom of the mold F., the spring e Was compressed, and now as the rod d begins to move upward theplunger b remains in its lowest position and forms an abutment for the sliding blocks 7a until the rollers i are carried out of engagement with the blocks. When the plunger h has been withdrawn from the mold, the work-table a is turned one-quarter of a revolution, and thereby the mold, lined upon its sides with the wrapper, is brought into position below the filling-tube fr, from which at the propel' time the exact quantityof matter required for one parcel is discharged into the mold.

The measuring and discharging of the proper quantity to be packed is performed in the following manner: The matter to be packed is contained in the hopper s, Fig. 2, from which it falls into one of the compartments of a rotating drum u, to which onehalf revolution is imparted by a connectingrod t', hinged to the lever o, Fig. 4 The said filled compartment j after the half-revolution of the drum u is placed exactly over the feedtube 0, from which the matter falls into the mold F, lined upon its two sides with the wrapper. After the contents of the compartmentj have been discharged into the mold the work-table a is turned into position III, and during the passage from position II into position III the cams y and a, projecting from the circular upright flanges of the support 17, successively act against the rollers 1 and 2, forcing the sliding plates w and .fr in turn across the upper surface of the mold and folding the parallel projecting edges of the wrappingpaper over the contents. lVhile the mold is in position III, after the slidingplates are withdrawn, the stamp 3, Fig. 5, is actuated by the eccentric K upon shaft H and moves down and compresses the folded edgesof the wrapping-paper and the matter contained in the mold. The stamp or plunger 3 is connected to its rod 4 in the same manner as heretofore described with reference to the plunger b and its shaft d. The rod 4 carries levers of the same kind as the levers g and provided with rollers 5 and 6, which when the plunger 3 is in its lowermost position move inwardly and engage the sliding blocks 7c, pressing the same firmly against the contents of the mold. By this. means the matter discharged into the mold will be well distributed and compressed by the vertical pressure of the plunger 3 and the longitudinal pressure of the blocks k under the influence of the rollers 6. When the plunger 3 and the rollers 6 vhave receded, the work-table a. is moved into position IV, and while moving the cam-surfaces 7 and 8, Fig. 1, act against the rollers 9 and 10, forcing the verticallydisposed sliding plates 11 and 12 toward each other across the end of the mold, thus folding the paper from the two sides of each end of the mold. As the sliding plates 11 and 12 advance the blocks 7a recede from the end of the mold, such receding motion of the blocks k heilig obtained by means of the hinged arms 14, Fig. 5, connected to each other by a common pivot which slides up an inclined surface 13, mounted upon the frame below the table. The package upon arriving in position IV has its upper side infolded within the paper, and at each end the paper has been folded from both sides inwardly, the upper and lower side of each end remaining still unfolded. The fixed support 17 of the work-table a is provided with a corresponding aperture 15, which registers with the bottom of the mold in position IV, whereby the package when placed in position IV corresponds with said aperture 15. A forked plunger 16, carried by a projection from the plunger-rod d, Fig. 2, and moving down with said plunger-rod, engages the parcel between the members of said fork and forces the parcel down intothe aperture in the support 17, at the same time folding the paper at the ends from the upper side and also causing the edges of the aperture 15 to fold the paper from the lower side across the end as the parcel enters the said aperture. Thereupon the parcel is pushed out of said aperture at the lower side of the support 17 completely wrapped.

If it be desired to apply a second wrapper around the same parcel, this may be done in the following manner: A second work-table 18 is arranged below the main work-table a, but eccentrically to the same, and is rotated at regular intervals corresponding with the rotation of the table a. The said table 18 is provided with four molds I II III IV, similar to those of table a, (but without the sliding IOO blocks c,) and the folding mechanism of said molds is the same as described with reference to the mold F of table a, Fig. 1. A blank of paper or other wrapping material is laid on the mold in position I, and by the rst partial rotation of the table 18it is placed below the aperture 15, and the parcel discharged through said aperture, as before described, forces the paper blank into the mold and simultaneously as it enters the same mold. folding the blank into the shape of the letter U, and in its progress from position II into position III the cam-surfaces 20 and 2l, projecting from the upright flanges of the support for table 18, act against the guide-rollers of the folding-plates 22 and 23 to fold the edges of the wrapper over the other side of the parcel. Then on the way from position III into position IV the cam-surfaces 26 and 27 act against the rollers controlling the foldingslides 24 and 25, thus folding the paper from both sides of the two endsv of the parcel. Finally the fork 28, similar to fork 16, before described, and projecting from the plungerrod 4, Fig. 5, engages the parcel, folds the wrapper from the upper side down, and forces the parcel through an aperture (similar to aperture 15) in the supporting-frame of the ta- IIO ' of the molds and folding device of table a and.

ofthe molds and folding device of table 18 are alike the operator merely has to place a fresh sheet of Wrapping material upon the mold when in position I. All further work is automatically performed by the machine, and the parcel is delivered with one wrapper from the work-table a or with two Wrappers from the work-table 18, as may be desired, in the manner described.

Therefore, having thus fully described my said invention, what I claim as new, and desireto secure by Letters Patent, is-
