To all 'ic/tom 'it may concern s' .l'e it known that l', EDWIN L. lliiiiincii, a citizen of the United States, 'and resident of Niagara Falls, in the county of Niagara and State of `New York, have made a certain n evv and useful Invention in Machines to Facilitate the Use of Cartons; and ll declare the following to be a full, clear, and exact descriptioii' of the saine, such will enable others skilled in the art to which it appertains tou-make and use the invention, refer ence being had to' the accompanying drawings, and to letters or figures ot reference marked thereon, which form a part of this s iecitication.

Figure l is' a side view of the left hand portion ofthe machine, showing mechanism for carrying cartons from the packing tables. l1 ig. 2 isa side view of'the right `hand portion of the machine showing devices for sealing the cartons. Fig. 3 is a, top view of mechanism shown in Fig. l. F ig. 4c is a top view of mechanism shown in Fig. `2. Fig. 5, is a transverse vertical section through line 5-5 on Fig, l. Fig. 6, is a detail perspective View showing carton in carrier link.

Thc invention relates to mechanism signed to facilitate the packing of biscuit, crackers or other delicate articles in cartons and sealing the latter, and` it. consists in the novel construction and combinationsof parts as hereinafter set forth.

The object of the invention is mainly to provide for a steady and even movement of` the charged carton, so that after it has been packed it een atie-nce be placed in position for sealing, and'tvill be continuously and steadily moved, and at the same time held securely in such position, throughout the operation of the mechanism and will not be subjected to irregular andA rough handling, which has a tendency to break v,or injure the articles packed therein.

. ln the accoii'ipanying drawings the figure 1 designates a 'framework supporting on each side an elongated packingl shelf 0r table Q, and centrally, above the level of said table a horizontal exteiisgm of an endless cartoncari'ying belt or chain 3, said belt or band extending through and engaging mechanism fo sealing the cartons as they are carried by said holt r.llin incchanism is also provided underneath and parallel to thecarton carrier extension with an endless belt 4, at about the level of the packing tables, fgihdelivei`- ing the articles to the packing operatives, who sit at the tables, and an endless belt for receiving and returning the pans, when such are used in the delivery, to the source of supply. The horizontal extension 0f the carton 60 carrier belt is shown at 3.

The framework l, has substantially parallel sides, and is of elongated form in order to provide for extended mechanism whereby the articles are broughtfrorn the place of supply, along between the packing tables, through the devices for sealing the flaps of j the cartons and for drying the glue, in such i wise` as to deliver the cartons packed and`-` sealed |for casing for transportation. The carton-carrying chain Sis therefore of considerable length, and is designed to be driven* by means of a sprocket Wheel E, geared p for the application of power. The el iny consists of links c, provided with rollei` j `b, adapted to engage tracks a, each'of said links having upright flanges c, rising from its cross-plate o2, and extending transverse the machine, designed to hold the carton in position for the Work to be done in connection therewith, as it is moved along the mecha nism.

rlhe carton which is employed for usegwith this-mechailiism' is designed to be --of rec tangular shape and folding` character, hav- 35 ing flaps or folding parts at its ends, these being extensions of its four walls, Of these tlaps or folds those which are upright in the carrieiare designed to meet or be in such near proximity that the opening between them can be closed by a narrow sealing strip. 'lhe'carrier chain Shaving' a horizontal extension in front of the sealing devices moves lengthwise the frame, along the track mand on the upper or direct branch thereof 95 cai ies'its links with their flanges projecting u ln the lower or return branchovfl this chain the links are arried with theirI ianges depending, such lower branch being some distance below the upper branch in the sealing portion of the machine, while in the front horizontal extension of the -fiaine the return track is immediately under the direct track, so that the 4return branch of the chain is carried along just under the carrying branch so as not to interfere with the packing operation. The direct and return tracks gradualljY separate at the end of the packing mechanism, and the direct track, which is4 substantially horizontal, is inteiinitted for 1w a short distance, at 6, ,in order to provide for the upper portion of the sprocket wheel E, which takes the place .of the track at this point in order to engage the'links of the chain. carrier at an intermediate point of its length. A slight downward inclination of the track just before its intermission at 6 is designed to facilitate the engagement of the carrier links with the sprocket wheel, this being insured by the guide bars 14,v which engage the links on their upper edges and :keep them to the tracks.

When the goods'to be packed are placed .upon the delivery belt 4 in pans, these are carried by said belt along the track arranged therefor, at the level of the packing ltables 2 and between the same. This belt 4 11s provided with transverse bars placed vin series at adistance from each other about `the length ofa pan, and when a pan has ar- 'rived at the end of this belt it is pushed ,onto a slideway S, which is operated by means of the engagement of said transverse is valso bar with bevel ends of the tracks of the slideway, so that these open or separate to allow the pan to fall upon the return belt 5, which rovided with transverse bars and L 'carries t e pan back to-the place of charging .the upp'er belt with the pans.

The biscuit or other articles taken from 't the belt 4 are placed by the operators seated "at the lateral tables in the cartons, which lili are temporarily closed at their ends by folding the Aflaps. Each carton is then A'placed between the `flanges of a link of the horizontal extension of the carrier chain 3, travcling upon the upper track a, whereby the carton 1s carried, between lateral walls 7 of the trarne, extending along the sides of the tracks, said walls serving to hold the flaps in folded position. The carrier chain extension in its movement toy that portion of the machine by which the sealing 1s effected, is engaged by the sprocket wheel E, and carries the carton between side walls G- having openings g, through which the upri ht flaps of the carton protrude by their e asticity, and are then held open bythe wall 'G and spreading slides z., having motion of reciprocation, in such wise that they are in proper position. for the `application of glue both to fing strips are applied along the upright flaps at their adjacent edges. These strips are cut from a ribbon reel R, by means .of lnvea'ie', after the depending portion of each ribbon has beenv supplied withV glue upon its inner surface by means of thegluing rollers V, and has been pressed upon A the carton by the pressure plates 9. The portion K of the mechanism has reciprocating motion in order that it shall have even movement with the chain 3 until the sealing strip has been applied.

Sometimes it Will happen that the operators at the packing table will omit to place a carton in a link of the carrier chain, and such link will be carried along empty. In

order to provide for this, at the place whereV lcarried along by the chain conveyer 3, pass between the heating chambers X, in engagement with the moving pressure walls ze, and ,f

in this way the glue employed in fastening the carton flaps and 'applying the sealing stripsi is caused to set and dry.

Operating mechanism for. opening and closing the flaps of the carton, applying the adhesive, and placing the sealing strips'on the carton, is described in Letters Patent No. 684,788, dated October 22, 1901, and therefore a more detailed description is not here re uired.v 1.

y this invention the sealing mechanism is provided with a carton holding extension over the delivery belt and in close proximity thereto, so that each filled carton can be placed by the packing operator, without caving his place at the table, in fixed position with relation to the carrier extension, whereb it will be 'heldtsecurely in such position w ile being conveyed during a conu tinuous and steady movement of such carrier to, and through, the mechanism for operatingvthe flaps of the carton and sealing the same. jecting the cai-tonto change of position or handling, which has a tendency to causef the articles contained therein to be broken or injured byA contact with its 'walls or with each other and'thereby, as frequentlyl hap'- And this is effected Without sub-l pens with-these delicate structures, result in' many offthe cartons useless.

Having described the invention, what I claim and desire to secure by Letters Patent is:

- 1r In a machine for facilitating the use of cartons, a central longitudinal endless belt, afserics of uniformly separated clasping means for holding cartons in fixed lrelation to the Ibelt' and to each other, continuous delivery meansfor material to bepacked in cartons, underand, parallel ltosanl series of nlongside said endless belt and said .series of means for holding cartons, und lateral ineens for holdingr cartone; lnlernl vertical. parallel walls for holding [he cartons closed above sind delivery mennev und extending tables for holding cartons .below :1nd along lside said delivery means.
