Fig. 11 is a detail view, scale enlarged, illustrating the construction of the spinners and supports therefor.

Fig. 12 is a detail View illustrating-the construction of the presser disk mechanism.

The paraflining machine is shown and described herein in connection with a machine for forming paper receptacles, as cups, a. portion of said cup forming machine only being shown, and in the drawings the numeral 10 indicates a portion of the frame of such cup forming machine upon which a turret 11 is rotatably mounted,having radial arms supporting forms or molds 12 upon which final operations in the making of cups are performed. As this machine forms no part of the present invention details of its constructlon and 'operatlon areomitted herein, the showing thereof being merely diagrammatic and illustrative as a means for supplying cups to. my improved paraflining mechanism, it being noted that a shaft 13 on said machine constitutes a-dr'i-vy ing shaft for the paraflining machine forming the subject matter ofthis application, which shaft 13 is driven in the regular operation of the cup forming-machine and which is for convenience merely made use of as the driving shaft for the machine, shown and described herein. Said cup forming machine is illustrated and described in my copending application of Serial Number 862,003, filed September 16/1914, and reference is hereby made to said application for such an understanding of the construction and operation of said machine as may be desired, although it is believed that such will not be required for a complete understanding of the invention forming the subject matter hereof, it being remarked that the machine of said application comprises a support for a roll of a strip of paper 14: from which the cup bottoms are formed.

The shaft 18 is intermittently driven as I by means of intermeshing beveled pinions (shown in dotted lines in Fig. 1) one of which pinions is secured to a shaft 23 mounted in brackets 24 secured to the frame and having a ratchet wheel 25 engaged by a pawl 26 on one branch of a forked arnr 27, mounted to rock on said shaft and connected by a rod 28 with the shaft 13, said rod being forked to straddle the shaft 13 and engaging a carrier driving cam 29 secured thereto and by means of which parts the carrier chain 18 given a one step movement at each rotation of the shaft 13, when said shaft, as in the present case, makes a complete rotation each time the formation of a cup on the turret 11 is completed.

The cups 30 are forced from the nrOlds 12 by any suitable means and in a manner to fall into a. chute 31 having a flaring mouth to receive the cups and so located that a shell 21, at each time the carrier chain stops in its step-b-y-step progressive movement, is located under the delivery end of said chute so that the cups are delivered *to and fall into each of the shells as they pass underneath the chute and as shown in Fig. 1 of the drawings.

A presser disk 32 is loosely attached to a presser bar 33 pivotally mounted on the frame and connected by a presser rod 34 with a lever 35 pivotally mounted in a bracket 36 supported on the frame 10 and connectedat one end with a rod 37 operatively engaged with a presser operating cam 38 secured to the shaft 13. A shell 21 is located underneath the presser each time the carrier chain halts in its step-by-step movement and by the mechanism above described the presser is forced into contact with each cup after it has been deposited in the shell, thus pressing the cup in firm engagement with the walls of the shell so that it will not be accidentally removed therefrom.

The shaft 19 is mounted in bearing blocks 43 that may be adjusted as by means of screws 44 to regulate the tension of the carrier. A supporting plate 45 is mounted on the frame in position to receive and support the cups as they travel the upward reach of the chain as shown in Fig. 1 of the drawings. The cups pass off the end of this plate and over a para ning casing within which they are coated with parafiin. This casing consists of a base 46 and a receiving shell 47 of cylindrical form secured to and supported on the base. The base'46 includes a pan 48 smaller in diameter than the base and secured to the upper edge of the base, thereby forming a heating chamber 50 between the outer surface of the pan and the inner surface of the base. A steam pipe 51 extends into this chamber to supply steam thereto for the purpose of heating the contents, as wax, of the pan which heated contents pass out through a drainage pipe A spinner carrier is rotatably mounted on a supporting post 53 rising from the bottom of the pan 48, this carrier comprising a base plate 54 and a spinner supporting plate 55 having depending flanges forming a gear chamber, which chamber is closed-by the base plate 54. A bearing and driving sleeve 56 extends from the plate 55- of the carrier and a spinner connecting shaft 57 is rotatably mounted in this sleeve and has a beveled gear 58 secured at one end meshing with a beveled gear 59 on a spinner driving shaft bearing driving pulleys 60 that may receive a belt from any suitable source of power. A gear 61 secured to the lower end of the connecting shaft 57 meshes with pinions 62.,secured to the ends of spinner shafts 63 rotatably mounted in spinner supporting sleeves 64 rising from the carrier and with their lower ends projecting into hubs in the gear chamber in the carrier, as shown in Fig. 4 of the drawings. Any suitable number (six in the construction herein shown) of these spinner shafts are provided, each shaft extending into a spinner chamber 84 formed by webs 85 radially arranged and extending upwardly from the plate 55, as shown in Fig. 10 of the drawings, and spinners 65 are secured to the upper ends of the shafts and are of a form to receive receptacles or cups 30 on their outer surfaces. A sprocket wheel 66 is secured. to the sleeve 56 and receives a carrier driving chain 67 ex'- tending to a sprocket wheel on a carrier driving shaft 68 mounted in bearings in brackets 6970 secured to the paraflining casing. An arch 71 is secured to and extends across the upper edge of the receiving shell and contains the bearings for the up per end of the connecting shaft 57. A bracket 72 depends from the under side of said arch and contains a brake 73 that surrounds -.the sleeve 56, a bushing 74 of any suitable material located Within the brake being held in frictional contact with the sleeve as by means of a clamp screw 75.

Each of the sleeves 64 has an extension 76 with a mouth 77 from which an air passage 78 leads through said extension and sleeve and opens within the spinners 65 that have ejecting slots 79 in their upper ends. As the carrier is given a step-by-step rotation by means of its driving connection with the shaft 23 that has an intermittent movement as hereinbefore described, a mouth 77 is located, each time the carrier stops, underneath an air delivery opening 80 from a chamber 81 in a hub 82 rising from a plate 83 secured to the upper edge of the shell 47 of the paraflining casing and projecting over the edge of said shell. A valve case 86 is mounted for reciprocating movement in the arms 87 of a bracket 88 secured to a peripheral flange extending about the upper edge of the shell 47. The valve case has a valve chamber 89 closed by a cap 90 secured to the case and receiving an air supply pipe 91 that extends to any suitable source for air under pressure. -A valve 92 within the chamber 89 has a valve actuating rod 93 extending downwardly through a nipple 94 that has its lower end extending into the chamber 81. An actuating disk 95 on the lower end of the rod 93 is adapted to engage a shoulder in the chamber 81 at a point posite end, said arm being pivotally supported at one end on anysuitable part of the machine, and having a roller 101 resting in contact with a valve operating cam 102 secured to the shaft 13.

-This cam is shaped and the parts are mounted and timed in their operation tomove the valve case downwardly at each time a mouth 77 is presented underneath the air delivery opening 80. In such movement of the case the disk 95'strikes the shoulder in the bottom of the chamber 81, lifting the valve 92 from its seat and permitting air to flow into the extension 76, which action creates a blast of air from the passage 78- and within the spinner .65 thereby blowing the cup 30 from the spinner. In this upward movement of the cups from the spinner, they are guided by fingers 103 extending in a curved path to cause the cups to fall into a trough 104 by which they are delivered to any suitable point.

It will be noted that the spinners and the cups thereon are rapidly rotated by the mechanism hereinbefore described and that while thus rapidly rotating the carrier containing the chambers 84 within which-the spinners are mounted is also rotated t revolve the spinners and the cups about t e Y axis of the carrier tobringthe spinners su cessively in position for the different oper-'.

connected up to receive the intermittent movement imparted to the carrier chain, makes each stop in its step by step movement with a spinner directly underneath a supporting shell, so that the cups as they are forced from the shell drop on to the spinners and immediately take up therotative movement thereof. The pusher 105 is located at the end of a downwardly projecting bar from a pusher lever 106 pivotally mounted on a pusher support 107 secured to and rising from the frame, The lever 106 .is actuated by a pusher rod 108 extending downwardly and having a forked end straddling the driving shaft 13 and with a roller in engagement with a pusher operating cam 109 secured to said shaft, the movements of the pusher being so timed that one. or more downward movements will take place during the dwell of each of the supporting shells therein.-.

After each receptacle has been deposited upon a spinner, the spinner carrier is given a one step movement to locate the spinner in due course underneath a spraying nozzle 110, the, carrier rotating in the direction indicated by the arrow shown in Fig. 3. A spraying chamber plate 111 of substantially the crosssectional' shape of the chambers 84 is secured to the upper edge of the shell 47, projecting inwardly therefrom in 1 0- said chambers at the location of the airsup' ply. The nozzle'110 is connected by pipes 113114 with a delivery pipe 115 extending from a pump 116 of any ordinary construe tion and which has a pressure chamber 117 the pipe 115 having a blow-ofl 118. Said pump is located ih'a wax supply tank 119 surrounded by a heating chamber 120' within a jacket 13,7 and into which steam is introduced through a steam pipe 121 connected with a main steam supply pipe 122extending from any suitable source of steam supply. The drain pipe 52 from the pan 48 empties into the tank 119 through a troughv 138, all the surplus wax that flows ofl from the cups in the waxing process, dropping on to the plate-55, and, passing through strainers 123 covering notches 124 in the edge of the disk, and in each spinner chamber therein, flows back to the'wax'supply tank 119.

The pusher 105 is located immediately tion, the spinners continue to rotate the cups to clear therefrom any surplus wax that may be contained therein, and this takes place at the clearing station and each chamber at this point becomes a clearing chamber. The next position of the chambers as the carrier halts in its step-by-step movement is at the ejection station, and as each chamber 84 comes to rest at this point and underneath the plate 112, such chambers become ejection chambers.

The rate of rotation of the spinners and therefore of the cups thereon, is so regulated that all ofvthe surplus wax will be thrown from the cups by centrifugal force, and the provision of a clearing station or clearing chamber enables this operation to be well done. As a further means for regulating the amount of paraifin that will be deposited upon the cups, a regulating pipe 139 is pro vided extending from the delivery pipe 115 into the tank 119, said pipe having a valve 140 for regulating the flow through said pipe. If this valve be open to any extent, a part of the parafiin taken up by the pump will be passed back to the tank, and the amount of flow passing through the spraying nozzle 110 onto the cups may be thus nicely regulated. I v

The pump is operated from the shaft 13 by means of a gear 125 thereon, meshing with a gear 126 on a pump actuating shaft 127 mounted in suitable bearings in the frame and having secured thereto a'crank disk 128 with a slot129 extending thereacross to receive a crank block 130 having a crank pin 131 projecting. therefrom. The block 130 is adjustable along the slot 129 and is secured as by means of screws passing through slots in the disk, block, or both, as shown in Figs. 8 and 9, this to regulate the amount of movement of the pump plunger. The pin 131 engagesa yielding block 132 held between springs 133 in a pump rod bar 134 secured to an end of a pump rod 135 the other end of which rod is connected to the plunger of the pump. This connection will permit a forced stopping ofthe move ments of the pump plunger without injur to the parts, the rotation of the crank disk being permitted under such conditions.

The cups being delivered to the carrier 20 through the chute 31 are carried along in the direction indicated by the arrow in Fig. 1, and some time thus elapses between the ,delivery of the cups to the carrier and the paraflining operation, 'so that the adhesive. used in making the cups has a chance to dry before the cups are subjected to the paraflining operation.

The further operation of the machine will be readily understood it being briefly stated that the operation of the air valve is timed to correspond with the step-by-step movements of the spinner carrier so that the air blast takes place at each time said carrier stops its rotating movement.

In accordance With'the provisions of the patent statutes, I have described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is only illustrative, and that the invention can be carried out by other means.
