To all whom itmag concern:

Be it known that 1, Joan N. HAHN, citizen of the United- States. residing at- Cleveland. in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Machines for" Pasting lasteboard Packages, of which the following is a specification.

My invention relates to a machine for pasting pasteboard packages, and the invention consists in a machine adapted particularly to make effectual the pasting of the flaps or folds of the package after the paste has been applied and adapted to hold the package within a given line of travel between opposed surfaces until the paste has so thoroughly set that the flaps will remain closed or sealed and not fly open after being discharged from the machine.

In making up pasteboard or like packages, parcels or boxes, say rectangular boxes with flaps or folds adapted to be turned or hent inward over-other folds of the box, it has beenv found necessary to hold the flap or fold down until the paste became suiticiently set or absorbed to secure the flap t i I without further assistance. Such flaps usually are bent at the edge of the box and have quite. a considerable outward spring tendency so that if they are coated with a comparatively soft paste they will spring open notwithstanding and pull away from the paste, that is until the paste has become set. Something must, therefore. be done to hold the flaps down after pasting until there is sufficient strength dewaloped. in the paste itself to keep them closed. Various makeshifts have been employed from time to time by different manufacturers to accomplish this purpose, but so far as my observation and experience go such devices have entailed a great deal of labor and at their best have been exceedingly primitive and unsatisfactory, and where a large output of boxes is necessary the devices here-- tofore have been found utterly inadequate.-

I have therefore conceived the invention herein which consists in a machine which is adapted to convey the ,freshly pasted boxes in succession one after the other with the flaps folded and pressed down where they belong and which will hold them down untihthe paste attains'a consistency or .-adhesiveness which alone will do" the work and no artificial help is further needed. At least three things are essential to an opera tion of this kind, namely, that the box should be carried by the machine in such manner that the flaps or folds will be held down by a sutlicient and sustained pressure, much as they would be held by an outspread hand or other means gently pressed upon the flap: secondly, that the length 0. the machine should be such that having received a box in a raw state of paste at one end it will care for the box until it is discharged in a finished state at the other end, and thirdly. such artificial means as applied heat or blasts of air to the box in transit as may be helpful to its more or less speedy drying. Of course if-the travel be rather slow or the machine sufficiently long these helps need not be extended. Much will depend also upon theconsistency of the paste, the nature of the material pasted, and

other conditions attending such work, but in any event the essentials of the machine are those which will take the box with its raw pasting at one end and deliver it sufiiciently dried at the other endof the machine to. prevent the flaps from springing loose or breaking away from the paste.

Referring to the accompanying drawings, Figure 1 is a plan viewof the machine, and Fig. 2 is a side elevation thereof. Figs. 3. 4, 5 and 6 are details of different parts more or less in section as hereinafter fully described. The machine thus shown comprises a suitable main frame F of whatever length may be deemed best, say twenty feet more or less, and which is provided with two endless a )l'OllS B and B running in horizontal parallel lines over drums D and D or their equivalentat the ends of the machine. Said aprons work in connection with rollers R and R top and bottom of a channel or passageway for the boxes A, according to the depth of the boxes. The-said rollers are in series and comparatively near to each other successively and relatively small and so arranged or disposed in each series that several of them will be in acting relations to a given box as it asses through between them. To this end also the lower series of rollers R is set in a suitable frame E fixed to the main frame as to its elevation and carrying the said drums D in its ends over which the apron A passes, the arrangement being such that the said apron rests over the said rollers. The upper rollers R are set in'a frameG adapted to be raised and lowered in respect to the lower frame and rollers according to the size of the box and the amount of pressure to be exerted upon the same. Said upper frame is slidably suspended upon the main frame from both ends and is controlled as to elevation. by means of sprocket chains C, or their equivalent, run over sprocket wheels W arranged upon a shaft S and adapted to be rotated and for the purpose of winding up or letting out the said chains according as the said frame is to be raised or lowered. The said s rocket mechanism is controlled from a sha t S by hand wheel 2 thereon and a pinion 3 meshing with a gear wheel 4 on shaft S and adapted to operate said shaft S and all that it carries thereby. A pawl and ratchet 5 serve to hold any rotation that may have been given to shaft S by wheel 2. Said chains C extend to the respective ends of the frame G and when the wheel 2 is rotated the arrangement and connection of the working parts is such that both ends of the frame G are raised or lowered uniformly, thus making the channel for the boxes uniform throughout its length and providing even pressure at all points.

ower is applied or supplied from any suitable source, such as a motor M which is belted 01' geared as at M to a line of mechanism running to what may be termed the rear drums D and D of the machine, a shaft 6 having bevel gears 7 meshing with bevel gears 8 on the said drum shafts and applying positive driving power thereto.

'This also enables me to cause the machine or said aprons to travel at any desired speed, slower or faster, and move the boxes A along through the machine from end to end with the effect that the paste is set when they are discharged from the machine.

Power is applied to the drive shaft S from the motor through a shaft 10 having a pinion 11 at one end and a worm 12 at the other end engaging a gear wheel 13 on shaft S which in turn operates shaft 6. The foregoing or any other or equivalent power transmitting means may be employed with the understanding that it is such as to actuate said aprons uniformly as to speed and in the same direction.

Either plain surfaced aprons A and A or their equivalent adapted to carry the boxes and pass uniformly on the folds thereof may be adapted and be within the spirit of my invention.

Bevel gears 7 and 8 for upper drum D are mounted in a bracket 15 secured to movable frame G (see Fig. 6), and a slidablc key connection 16 is used between gears 7 and shaft 6 to permit up and down movements of frame G.

-W'hat I claim is A machine as described for pastingand drying boxes having two endless aprons op positely disposed parallel to each other and 1 two frames having rolls at their ends over \VhlCll said aprons travel, a series of rollers for each apron having hearings in said frames and exposed above theopposed surfaces thereof, means to space sald frames 'apart at varying distances according to the sizes of the boxes to be pasted comprising flexible adjustable 'suspensory supports for the upper of said frames extending from the middle of the machine to both ends of said frame, and means to jointlyoperate said aprons at the same rate of speed and in the same direction, the said aprons being. stretched over their respective frames and running in contact with said rollers, the lower of said frames being fixed'in the main frame.

In testimonv whereof I ailix in presence of two witnesses J OHN' N. HAHN.
