PARAFFINING APPARATUS.

'Lpplicatmn filed July 14, 1921. Serial No. 484,604.

To all whom it may concern:

Be it known thatI, IRvmc STANLEY, a citizen of the United States, and a resident otthe borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful Improvements in Paraifining Apparatus, of which the following is a specification.

This invention relates to apparatus for impregnating articles made of paper with paraiiine to make the same impervious to moisture and liquids, and relates particularly to paraiiining of receptacles or containersmade of paper, and it is the primary object of the invention to provide apparatus of this character for treating articles successively in a continuous manner and provide apparatus for this purpose whichis simple in structure, and eflicient in use.

In the treatment of paper articles to be paraflined it is essentialfor the efficient im-' .pregnating of the material by the parafline I that the parafiine be in'a highly liquid state,

and after the article has been subjected to the parafiine bath that the article be quickly chilled in I order to cause the parafiine t0 eedf 1 evenly coat the article, and it is a further object of the invention to provide improved means for subjecting the article to the parafline while in a heated and dissolved structed and arranged with means to cause the articles carried by the conveyer to be mmersed in the parafline without immersing the conveyor with the consequent interference in the efficient operation of the ap-.

paratus and necessitating the constant cleaning of the same. 7'

t is a further object of the invention to provide the conveyer'with improved arti- V cle carryingmeans arranged to automatically pick up an article from a support and transport the same through the paraflining chamber or receptacle and refrigerator, and to release the article from the conveyor as it is delivered from the refrigerator.

.It is a further object of the invention to provide apparatus of this character to be used in connection with apparatus for making paper receptacles or containers, and to provide means to deliver articles from said apparatus to the article carriers of the .conveyer.

Other objects and advantages will hereinafter appear I In the drawings accompanying and forming a part of thisspecification Figure 1 is a perspective view of an apparatus illustrating 'an' embodiment of my invention;.

means to apparatus for making paper receptaclcs or containers, and the means for feeding the articles from said delivery means to the support.

Similar characters of reference designate like parts throughout the different views of.

the drawings.

In the embodiment of my invention shown in the drawings .the operative mechanism is mounted upon -a framework consisting of a Figure 7 is a detail view in plan of a por-- articles by pair of parallel angle irons 9 rigidly connected by cross bars and Supported by legs or standards 10. i

A tank or receptacle 11 having an open= ing in the top with a removable cover 12 and to contain parafline, as shown at 13, is mounted upon the connecting cross bars of the framework the paraffine being dissolved and maintained in a dissolved and liquid state by the application of heat, shown as a coil or pipe 14 in the receptacle connected to a series of heat supply such as steam.

-A' refrigerator is mounted upon the cross bars of the framework in juxtaposed relation to the parafline chamber and comprises a chamber or tank 15' having an opening in the top with a removable cover 16, said chamber containing a ice 17, and a cooling coil 18 extending longitudinally thereof above the refrigerant.

refrigerant such as mounted upon the framework below the upper stretch of the conveyer and at the entering end of the parafline chamber 11.

As stated the apparatus is to be used in connection with apparatus. for making the article 33 and is delivered from such apparatus to the shelf 38. For this purpose a second conveyer 39 is provided a belt passing over rollers 40, 41, and actuconsisting of The para'ffine chamber has alined openings 'ated by rotating the roller 40 from a suit- 19, 20 1n the opposite end walls, and the refrigerant chamber also has aline'd openings 21, 22 in the opposite end walls in line with the openings in the parafline chamberand the opening through the, coil 18. In the structure of the coil shownin Figurei2 the Wall of the,coil is perforated, as shown at 23, the coil being connected to a blower, indicated in a general way at 24, to discharge a plurality of sprays of jets of air from the coil in a direction toward the interior there'- The article or articles to be paralhned are transported to the paraifine chamber and the refrigerator by a conveyer comprising a pair of sprocket chains 25 passing around a pair of sprocket wheels 26 fixed in spaced relation on a shaft 27 and sprocket wheels 28 fixed in spaced relation on a shaft 29 and guided below the paraflining chamber and

32, and by means of which bars rangement of the-sprocket wheels the chains are maintained in parallel and spaced relation. The-mounting of the sprocket wheel shafts 27 and 29 are so arran ed that the upper stretch of-the conveyer Wlll pass through the openings 19, 20 of her and the openings erator.

The apparatus is adapted to parafiine articles of different shape and character and in the present instance is arranged to treat 21, 22 of the refrigreceptacles of truncated conical form having a closure in the end of greatest diameter as shown at 33. To support and transport the conveyer the conveyeris arranged with a series of successive article carriers, each of said carriers consisting of a member 34 fixed to the transverse bars 32 substantially midway between the ends thereof and the conveyer chains with the end 35 bent'at right angles to extend inwardly the paraffining cham- The conveyer 25 is intermittently actuated and during the periods of rest the article is delivered by the plunger or ram 46 from the conveyer 39 to the article support 38 and to permit of the positioning of the article on the support the arm 36 of the article carrier is moved to the position shown at 36- 111 Figure 2 by a finger 47 carried by the ram engaging a projection 48 (Figures Guides The articles 6 and 7 on the arm, rocking said arm Y against the tension of the spring 37 As the ram is returned to initial position the finger 47 is released from the arm projection 48 when said arm will be moved by the tension of the spring 37 to engage the end of the receptacle on the support 38 and position said receptacle with relation to the supporting fingers of the arm 35 of the carrier.

The travel of the conveyer through the parafiine chamber 11 is guided in its move-v ment to cause the articles being transported by the conveyer carriers to be entirely immersed in the paraffine without immersing the conveyer chains therein. For this purpose a pair of guide rollers 49 are mounted within the parafiine chamberover which the conveyer chains pass, a second pair of guide rollers 50 being rotatably supported in juxta-posed relation to the rollers 49 and under which the conveyer chains pass, the conveyer chains passing from said latter rollers under a pair ofguide rollers 51 supported in spaced relation to the rollers 5.0

and to rotate on axes parallel therewith, the

chains passing from said latter rollers over guide rollers 52. As will be clearly observedfrom Figure 2 by this arrangement of the

guide rollers

49, 50, 51 and 52 the articles carried by the conveyer iii its travel through the parafline chamber will cause the articles to be immersed in the parafiiney- As the conveyer passes from the rollers 52 the receptacles will be in an inclined p0 sition thereby permitting any of parafiine contained therein todrain from the receptacle. It will be noted that in the passage of the conveyer through the parafiine chamher that the conveyer will not be immersed a gui e 53 rocking the arm 36 and releasing the article therefrom, such article dropping onto a chute 54 and being able receiver R Figure 5.

The conveyer is operated intermittently deliveredto a suitfrom a suitable source of power and is shown as being actuated by pawl and ratchet mechanism consisting of a ratchet wheel 55 fixed to shaft 27 of the sprocket wheels 26 and actuated by a pawl 56 pivotally carried by an arm 57 hung on the shaft 27. The arm is oscillated or actuated by a rod 58 operatively connected to a cam 59 on a drive shaft 60 and constituting a part of the apparatus for making the receptacles.

In the operation 01E the apparatus the articles are delivered from the receptacle making apparatus to the, conveyer '39 as shown in dotted lines at 60in Figure '2. The articles are carried by the conveyer until they are arrested by the stop 45. During a period of rest of thearticle conveyor 25 the articlesare delivered from the conveyer 39 to the support 38 b the plunger or ram 46, the plunger in its elivery movement causing the finger 47 to engage the projection 48 of the arm 36 moving the same to the position shown at 36 in Figure v2, such movement of said arm being previous to the delivery of the article to the sup-' port 38. The plunger immediately recedes from its feeding position thereby withdrawing the finger 47 from 'the arm projection 48 causing said arm to move to position with the fingers thereof to engage the end of the receptacle and causing said arm to position the receptacle relative to the supporting fingers of the arm 35. An intermittent movement is then imparted to the conveyer positioning a successive carrier with relation to the support 38 whenithe operation of de- The articles the parafliue in the receptacle; and a re livering a further article 39 is r'epeated.
