To all whom it may concern;

Be it known that I, ALBERT BEVERLEY, a subject of the King of Great Britain, residing at 46 -Tynemouth road, 'Gormnge Park, Mitcham, in the county of Surrey,

' "ing four bottles atone time but this num.-

her may. be varied.

Figure 1 is a plan of the machine; Fig. 2 is a transverse section; Fig. 3 shows a detall; Fig. 4 is a left hand end view Fi s. 5 and 6 show details; Fig. 7 shows part the mechanism for operating the molds and neck rings; Figs. 8 to 15 show details. Figs. 1, 4 and 12 are to a smaller scale than the others. p

1 is the main shaft having on'it four pulleys on which runs the driving belt. The first pulley 2 is on a sleeve on the shaft; the Second 3 is a loose pulley, the third 4,is fast with the shaft. and the fourth is on a sleeve. The fourth and fifth are narrow pulleys so that the'belt may drive both together. Fasten the shaft are two pinions 6 one at either end of themachine; these gear with vertical racks 7 depending from" the table 8 which is thus capable of an up and down movement in Tuides on the frame of the machine. The tile-carries four parison molds 9. The molds may simply be dropped into sockets 10 on .the table and these sockets are preferably capable of vertical movement with regard to the table, being mounted on springs 11 and carried by pistons 12 moving in cylinders 13 open to the atmos-.

phere. This allows any mold to stop short of its highest position if: too eat a' charge has been placed in it. Herea er I will describe the machine as if there were only one mold and one socket on the table for however many sockets there be on the table, that is however many be the bottles than can be blown at one operation, themechanisms one bottle.

I Above the socket 1 0 is a stationary hollow core rod 14 so situatedthat as the table rises the core. rod enters the mass of glass 1n the parison mold as shown in Fig. 3. It

must be understood that to save drawing Fig. 2 shows not only a parison mold with its charge below the core red but also the finishing mold in position around the core rod and that such finishing mold must be withdrawn and the finished bottle removed from the core rod before the table rises.

will simply be repetitions of that used for Fast with the pulley 5 is a pinion 15 meshing with a pinion 16 on a shaft 17 on which is a bevel wheel 18 gearing with a bevel wheel 19 on a vertical spindle 20. The socket of the parison mold is supported b a pinion 21 meshing with a pinion 22 whic is free to slide up and down the spindle 20. As the table 8 rises, an arm 23 upon it raises the pinion 22 which is thus always level with the pinion 21 and therefore the mold 9 is rotated on its axis during the rise of the table. When the table reaches its highest position it comes against a lover 24 (see Fig. 4) pivoted to an adjustable'bl'ock; 25 and connected by a slotted link 26 to a lever 27 fulcrumed on the frame at 28. The

lower end of this lever moves a slide 29 along a fixed guide 30 and to this'slide is connected one end of a link 31 pivoted to an arm 32 which can turn on a fixed pivot 33. The other end of the link 31 is hinged to a rod 34 running along the rear of the machine and connected by a bar 35 to the belt shifter 36. The effect of the parts numbered from 24 to 36 is that when the table strikes lever 24 the belt shifter is moved to the right and the belt is removed'from pulleys 4 and 5 to pulley 2. The table is thereforeraised no higher. In the path of the table and at each end thereof I arrange a detent or slide 37 connected by cross links 38 (See Figs. 4 and 5) to a detent 39 in sucha way that when the table strikes slides. 37 and moves them toward the front of the machine, the detents 39 move rearwardv beneath the table and hold it up. While the table is thus retained, the charge in the mold is marvered as follows :As the belt shifter moves to the right an arm 40 (see Fig. 1) upon it comes against the rear end of a lever 41 and I rocks it on its ivot 42. To the rear end of this lever is ing'ed a link 43 connected Elli this

to the bottom of a lever dt by which a bevel wheel t5 on a shaft 46 can be moved into engagement with a bevel pinion 41-? fast with the pulley 2. @n the shaft 16 are two bevel pinions 18. each of which has teeth around one half only of its periphery and with these mutilated pinions meshes a bevel wheel 4.9 which is moved on its shaft 50 by a lever 51 pivoted at 52 and having its lower end hinged to the leverdl. This shaft 50 has fast on it a spur wheel 58 which meshes the pinion 16 already described. its therefore the pulley 2 rotates the shaft 50 is rotated first in one direction and. then in the other and the mold is consequently rotated first in one direction and then in the other, marvering the charge within it. if the machine be required to make bottles other than cylindrical, the marvering may be obviated by removing the fork on lever 51 which ems braces bevel wheel 49. @n the shaft d6 moreover is a pinion 5d gearing with a'pinion 55 on a cam shaft 56 on which is a cam 57 adapted to move to the left a. rod 58 which engages by pins 59 (see Figs. 1 and 4) the rear ends o'ta pair of horizontal levers 60 the front ends of which have upon them inclines 61 which bear against the lower ends of levers 62 turning on horizontal pivots 63 while their upper ends engage the slides 37. When therefore the rod 58 is shifted to the left the slides 37 are moved rearward and the detents 39 are withdrawn. The table therefore falls by its own weight and the charge is left hanging to the core rod and neck ring as seen in Fig. 6. The neck ring 64 just referred to is constructed in two halves which are closedaround the core rod before the table begins to rise as will be described later and the glass is forced by the rise of the mold up between the neck ring and the core rod. As soon as the table has fallen suiliciently to bring the top of the parison mold below the bottom of the charge,

the finishing mold maybe closed upon the half formed bottle. This is effected as follows :The mold is formed in two halves 65 carried by arms 66 (see Figs. 2 and 7 which can turn around a pillar 67 and linked by links 68 to a longitudinal bar 69 to which are attached the rods 70 of pistons '71 moving in cylinders 72 arranged one at each end of the machine and supplied with compressed air by a supply pipe 73. Each cylinder has an inlet yalve 74: in a valve box 75 cooperating with ports 76 admitting air to each end of the cylinder while 77 are exhaust valves cooperating with exhaust ports 78 by which the pressure at each end of the cylinders can be relieved. The inlet valves 74 and exhaust valves 78 have at their, rear ends arms 79 pivoted to a bar 80 (see Figs. 1 and 8) at the top of a lever 81 pivoted at 82 and having at its lower end a pin 83 between pins 84, 85 on rods 86, 87 held by noeaaee springs 88 against came 89, 90 on the cam shatt 56. When the cam 89 moves the rod 86 to the left, the valves 77 are turned so as to put the front ends of the cylinders to exhaust while the inlet valves 7d are turned so as to admit air to the rear of the pistons which therefore move forward bring the bar 69 forward and therefore close the molds as shown in Fig.2. As soon as the molds are thus closed, ll supply air to the core rods; this is effected as follows z The bar 69 has attached. to ita slide 91 (see Figs. 1 and 9) on which is an incline 92 and as the bar moves forward as above described this incline pushes up a valve 93 in a valve box 9d connected to the air pipe 73 so that air can pass to a pipe '95 leading to the top of the core rod which is suitably perforated so that the air can pass into the interior of the glass and below it to the form shown in Fig. 2. The core rod will of course be varied in shape and size to suit the various molds in use and in some cases may have grooves, flats or indentations formed upon it to enable it to hold the glass while the parison mold is descending and the molds closing. The core rod is'preterably cooled by oil which is supplied to a chamber 96 and passes down an oval tube 97 (see Figs. 10 and 11) to near the bottom of the core rod and returns up a central pipe 98. Blowing continues until a drop in the cam 90 comes opposite the end or the rod 87 which is then moved to the right by its spring 88 so turning the valves 74 and 77 to move the pistons 71 rearward. This brings back the bar 69 cutting 01? air from the core rods, putting them to exhaust by port 99 and opening the finishing molds; All this time the belt has remained on pulley 2 but now a wiper 100 on the camshaft 56 comes against a pivoted catch 101 and lifts it out of a slot 102 in the rod 34 which isthen pulled to the left by the spring 103 (see Figs. 1 and 12) this brings the belt on to the loose pulley 3 and the machine stops. The finished bottle can now be taken oil the core rod and a fresh parison mold that has had a charge gathered in it meanwhile can be placed on the table. An attendant now moves to the left a starting lever 104 (see Figs. 1 and 12) to which is coupled by a cord 150 passing over a pulley 151 a rocking arm 105 provided with an incline 106 which lifts the rod 34 so that a shoulder 107 on the rod which had been caught by a fixed stop 108 is freed from that stop and the rod is moved to its extrfeme left position thus shifting the belt on to the pulleys 4 and 5, from which the cycle of operations already described is repeated.

The lever 104 has pivoted to its lower end a rod 109 parallel to the rod 34 and carrying two inclines 110 (see Fig. 12) which as this rod moves to the right come against the lower ends of two vertical levers 111 and move these ends forward; the upper ends therefore move back bearing against fingers 112 adapted to push rearward the front parts of the inlet valves 74 thus uncovering the ports 76 of the front of the cylinders and relieving the pressure in front of the pistons so that springs 113 are free to move forward a bar 114 (see Figs. 1, 2 and 7) which moves on guides 115 and is connected to the bar 69 moved backward and forward by the pistons. The bar 114 is linked by links 116 to the two halves of the neck ring 64 which thus close ready for the next parison mold to be raised around them.

Fast with the fingers 112 are rods 117 beside the valve boxes 75 and these rods are caught by catches 118 (see Figs. 1 and 8) which retain the front ends "of the valves in the position last mentioned until the valves are turned by the return movement of the lever 81 due to the spring 88 on the rod 87 when the upper end of the arm 79 of the inlet valve 74 lifts the catch, whereupon the spring 119 moves the front of the inlet valve forward again.

With the parison molds referred to and shown'in Figs. 2 and 3"I preferablyuse a rod or holder as shown in Fig. 13. "This consists of a main rod 120 with a spring stud 121 adaptedto enter the eye 122 on the mold and with a ring 123 adapted to fit over the top of the mold; to the rod 120 is pivoted a spring pressed shearing rod 124 the forward end of which is provided with a semi-circular knife 125 which cooperates with the ring 123 to shear off the glass when the gatherer considers the amount inthe mold sufficient.

For making bottles with a knock up or indentation in the bottom, abottom mold 126 is carried on a sleeve 127 sliding on the pillar 67. This sleeve has peripheral teeth 128 meshing with a segment 129 rocked on its pivot by a link 130 engaging a slotted arm 131 fast with the segmentand carried by an arm 132 on the bar 69 (see Fi 2). As therefore the bar 69 moves forward, the mold 126 is raised and swung into the position shown by a pin 133 on one of the halves of the finishing mold 65 which engages a hole in the bottom mold. When the finishing mold opens, the bottom mold is moved down and swung aside out of the way of the parison mold.

If it be desired to form a screw thread within the neck of the bottle, I provide a collar 134 on the core rod 14 (see Figs. 7, 14 and 15). This collar is withdrawn from the formed bottle as follows :Connected to the bar 114 which operates the neck ring is a transverse arm 135 provided with a rack 136 meshing with a pinion 137 on a longitudinalspindle 138 on which is a skew gear wheel 139 engaging a thread 140 onfthe collar. Astherefore the bar 114 m ves back the collar is turned and by reason of its thread it screws itself up into a nut 141 fixed above it as shown in Fig. 14. Or the collar may have an internal thread as shown in Fig. 15 and screw itself" up the core rod.

It'is obvious that various parts may be adjustable so that the machine can make bottles of, various sizes and shapes. Moreover the sockets 10 for the molds may be so carried bythe table 8 that their height above the table may be varied within considerable limits so that bottles of different sizes may be made at the same time.
