and useful Improvements in Machines for Gatheringand Shaping Glass, of which the following is-a specification, reference being had therein to the accompanying drawings. 1

The invention relates to new and useful improve-- ments in machines for gathering and for shaping glass, and consists in an improved machine for gathering glass in definite quantities from a pool or tank'of molten metal, together with cooperating mechanism for blowing the gathered glass to shape.

. The mechanism consists particularly in'tlie following:1n a. rotary, reciprocating frame, which carries a series of gathering molds, and in the means for operating the frame,'themolds, and in counterbalancing the Lira-me and attached parts. In the cooling of the gather-' ing mold, and the means for doing this cooling. In the construction of the blowing head and adapting it to molds having different-sized top openings; and the means for heating the pin core or plunger which makes the initial blow-opening in the blank. In the manner of supporting and operating the blowing molds, and providing means for attaching blowing molds of different size. In the construction of the cut-off knife, its

operating means, and means for adjusting it to different sizes of molds, and further in the construction, arrangement and combination of the parts, particularly pointed out in the claims.

On the frame is a motor. which I have shown as an electric motor 5, which furnishes the power for operating the machine. This drives, through suitable gears, the shaft 6 geared to and driving the vertical 16 is a suitable clutch operated through the con necting rod 17 and the lever 18, so that when the clutch .is thrown in, the wheel 14 and the carriage may be caused to travel along the track. In order to provide a drive mechanism for the carriage either way, I provide on opposite sides of the gear wheel on the shaft 12, the bevel gear wheels 19 and 20, either of which may be moved into engagement, and the engagement of either of which will operate the clutch 16.

it is desired to raise and lower the operating parts of the machine to and from the glass, and this is accomplished through the cam wheel 10, which has a cam groove 21, with which a roller wrist 22 engages. This roller wrist is connected to a slide 23, sliding in suit -v able bearings in the carriage frame. On this slide is a shaft 24 (Figs. 2 and 31), the ends of which are squared and engage in the slots 25 (Figs. 1, 32), in the pushrods 26, which at their outer ends are connected to the rock arms 27 on the rock shafts 28. These rock shafts 28 carry segmental gears 29 (Figs. 2, 40), engaging rack bars 30 on the sleeves 31 (Fig. 39), which are respectively connected to slide shafts which support the machine and through which it is raised and lowered in the manner to be hereinafter described.

, On one side of each push bar 26 is a hinged latch 32 i (Fig. 32), which is adapted to be dropped in front of the squared ends of the shaft 24, when it is desired to rotate the frame of the machine, as shown in dotted lines, Fig. 32. Thelatch may also be lifted out of engagement with the shaft 24, and the latter will reciprocate in the slot 25 without operating the push bars, as shown in full lines, Fig. 32. On each latch 32 is a lug 33 (Fig. 3]), adapted to be operated by the lev'ers 34 on the shaft 35, which iii turn is operated by the hand lever 36, having a suitable spring catch for holding it in its adjusted position.

When the latches are down in the position shownin dotted lines in Fig. 32, the reciprocation of the shaft 24 will cause the push rods 26 to.be moved back and forth and the shafts 28 will be rocked, likewise the gear segments 29, and the rack bars 30 with their sleeves 31 will be raised and lowered, and with them theentire operating parts of the machine above.

40 are two slide shafts supporting the machine and by means of which it is raised and lowered. These shafts slide suitable guide bearings 41 in the carriage frame, and also are guided by the brackets 42 also on the carriage frame; and also in guide sleeves formed on the brackets 44, on the under side of the carriage frame. At the lower end, each of these shafts carries the transverse sheave shafts 45, upon which are the sheaves 46. From these sheaves run suitable cables 47 anchored at one end to the carriage frame "hand wheel 58 for operating the same.

and passing over the idldr sheaves 48, andcarrying at their ends suitable balance weights 49 (Figs. 1, 3). These weights are of the proper size to counterbalance the operating parts of the machine above. 1 7

On each of the slide shafts 40 is a screw threaded portion 50 (Fig. 39) and on these screw-threaded portions are the nuts 51, having a worm wheel 52, which engages in a groove 53 in the sleeve 31, previously described.

54 is a shaft journaled invthe brackets 55, on the lower end of the sleeves '31 (Fig. 39'). "This shaft 54 carries worm wheels 60 meshing with the worm wheels 52. The shaft 54 has a sliding feathered engagement with a stub shaft 56, which in turn has a universal joint connection with the actuating shaft 57, supported in suitable bearings on the c arriageframe and having a.

The shaft 57 at its upper end, is proveded with a clamping nut 59 which, when the proper adjustment is obtained of the nut 51, may be tightened up and will lock the 54 and 57 from accidental rotation.

The shaft 54 is made in two parts, with a mortise and tenon engagement between them, and the meeting shafts with complementary teeth and notches 62 and clampjusted to exactly the same positionand then the bolts 63 put in position and the two sections of the shaft locked together. v

The upper ends of the slide shafts 40 support the grooved base ring 64 (Fig. 3), which supports the upper portion ofthe machine. This base ring 64 has a guide ring 65 guided by the vertical sleeve 66, which is in turn bolted to the carriage frame. Within the sleeve 66 is the supporting sleeve 67 (Figs. 1, 3, 5, 6), spaced from the sleeve 66 by the Webs 68, and forming between the webs the air passages 69. .Supported in and secured to the sleeve 67 is the post 70, being a stationary post, 1.. e., non-rotating, and around which the of the carriage frame, directly beneath the sleeve 66 and registering therewith.

81 is a stationary cooling air conduit in the pit below the machine, connected to afan or pump, and when the machine is moved into operating position with the tank, the upper end of the conduit 81 and the lower end of the conduit 80 are in alinement, as shown in Fig. l, and cooling air will be supplied to the working parts of the machine.

82 is a sleeve, sleeved on the post 70, adapted to vertically slide thereon but held from rotation by suitable spline, or it may be merely secured to the collar 83, which is a part of the base ring 64 (Figs. 1, 3).

84 is the lower spider, sleeved on the sleeve 82, having on its under face a projecting V-shaped circular rib 85, resting and turning in .a complementary V-shaped bearing 86 on the top of the base ring 64. This lower spider forms an air chamber for cooling purposes for the blank molds, and it also supports the upper frame of the machine. It carries an annular gear wheel 87 depending fromits under face, with which meshes the pinion 88 on the vertical shaft 89 supported in the bracket 90 secured to the base ring 64, and carrying at its lower end the gear wheel 91,

whichmcshes with the long vertical pinion 8, previously described as being driven by intermediate drive connection from the motor 5. The rotation of the pinion 88, it is obvious, engaging with the gear 87, will cause the rotation of the lower spider and the rotating frame carrying the operating parts.

The parts rigidly carried by the lower spider form in effect a'inirue carrying the operating parts around the center post, these parts comprising .a series of blank Jilflldflf neck molds, blowing molds, means for opening and closing these molds and admitting the vacuum and ,air under pressure for carrying out the various functions as will be hereinafter described.

1 The, frame supported on the lower spider carrying the operating parts is formed as follows:-Secured on top ofthe lower spider 84 are a series of pedestals 92. These are castings bolted to the upper face of the lower spider 84, and are arranged in circular series around the outer edge thereof, as shown particularly in Figs. 7, 8, 25. a At the top they are connected by the rods 93 with the top spider 94 (Figs. 1, 7, 8). This top spider 94 is supported at the top of the sleeve 82 and rotates thereon with the lower spider 84. Supported on the sleeve 82 are a series of horizontal cam ringsyhaving cam ways therein stationarily secured to the sleeve. These rings I number respectively 95, 96, 97,98, 99, Figs. 1, 7, 8. The revolving frame, composed of the lower and upper spiders, the pedestals, and the tie rods, carries a series of six sets of gathering and blowing molds, as illustrated in diagram in Fig. 9. As all the sets are alike, a description of one will suffice for a description of all, and I will therefore describe the construction and operation of one gathering mold, one blowing mold, the air, vacuum, gas and cooling connections, and it will beunderstood that the construction and operation of the other five are alike.

The operation of the machine is shown in diagram in Figs. 9, 10, 11,, 12, 13, 14 and 15, in which the first step of theoperation is to lower the blank mold to the glass, then gather a blank from the molten glass, then cut off ,the glass in the mold from that in the tank, while raising, then open the blank mold and inclose the blank within the blowing mold, and then to blow the blankto its finished shape, finally lowering the blowing mold to its vertical position and opening it to drop out the'finished article, and 1 will endeavor to describe the, parts in their sequence of operation. The blank mold 100 which is in two sections is illustrated-in enlarged section in Fig. 28, the sections being carriedat the outer ends of the hollow arms 101. These arms are pivoted on the vertical pivot 102, which passes through the blowing head arm 103, which, near its middle portion, is provided with the lateral hollow brackets 104 on opposite sides and connecting to adjacent pedestals 92. This arm 103 supports the blank mold, and neck mold sections, forms the suction and blowing head and carries a core or plunger for making an. initial blow opening in the blank. The

arms 101 have the brackets 105, which extendabove' the arm 103 and engage the pivot 102 tosimply give the necessary strength and rigidity to the pivotal support for these blank molds. The arms 101 have the lever extensions 106 beyond their piv'otj, which with the links107 form a toggle lever connection which is actuated to open and close the blank molds. The ends of the links 107 are pivotally connected to the sliding block 108, which slides" on the inner end of the blowinghead arm 103. This block 108 is connected to the roller wrist block 109 by .the rod and spring connection 110 (Fig. 18), and the block 109 is provided with a roller wrist 111, which engages a suitable cam way in the under face of the cam ring 96. By having a spring connection between the block 108 and the block 109, the cam ma y cause the blank molds to be closed, and then move the block 109 still further, so that the springs 110 tend to hold the blank molds yieldingly together, and also so that if anyglass should come between the two sections of the blank mold, the parts 'will not be broken.

Pivoted to the under side of the blowinghead arm on the pivot pin 112 (Fig. 20) are the two neck ring sections 113. These neck ringsections are connected by the links 114 to the sliding block 115, sliding on the rod 116, a

secured to the under side of the arm 103 and are operated by a vertical lever 118 (Fig. 8), which at its upper end is bifurcated and connects to a cross-head 119 (Figs. 8 and 19). This cross-head has an aperture through which slides the rod 120, and the cross-head is actuated by the spiral spring 121, abutting against a collar on the rod, as shown in Fig. 19. The rod is connected to the sliding-block 122, which slides on a rod 123 in the bracket 131, and carries a roller wrist 124 I working in the camway on the upper face of the cam ring 97, all as plainly shown in Fig. 8, this camway be-' ing properly shaped to open and close the neck mold at the times to be hereinafter described.

On the blowing head arm and working in suitable sliding guides on the upper face thereof is the blowing 103 are the two guide rods 129 (Figs. 22 and 28) and on these two rods slides the cross head 130 detachably carrying the core or plunger 140, which is adapted to make the initial blow opening in the glass blank. This plunger is made detachable in any suitable manner by engaging a socket 145, in which it is held by a spring pin 146 (Fig. 30). This cross head 130 is raised and lowered by means of a bell crank lever 141 (Fig. 8), journaled on a bracket 142 and connected by a spring link 143 with the slide 1.48, sliding,on the rod 155, and carrying a roller wrist 144, said roller wrist engaging with a camway on the upper face of the cam ring 98.

Supported near the outer end of one of the blank mold levers is a vertical tubular bearing 150 (Figs. 28 and 33), in which is journaled the rock shaft 151, which at its upper end has the crank arm 152, pivotally connected to the link 153, which in turn is pivotally connected to the slide 154 on the slide rod 155 in the bracket 142. The slide 154 has a roller wrist 156 engaging another camway in the upper face of the cam ring 98. The connecting link 153 being pivoted at opposite ends permits lost motion through a slotted pivotal connection to take care of the angular movement upand down of the shaft 151; atthe lower end of this shaft is secured the arm 222 carrying the cut-off knife 221.

cam flange 161 at the top of the guide sleeve 150, so that when the shaft 151 is rotated, it will first run down the inclined portion of the grooves 160 and then be moved laterally, for a purpose tobehereinafter described.

162 is a stay rod extending from the sleeve 163 secured to the cam flange 161, and tied to a cross bar 164 between two of the tie rods 930i the frame (Figs. 1, 7, 8).' The knife may be adjusted vertically by connecting the head 158 and the crankarm 152 at the desired points. Thus the knife can be adjusted to molds of varying length. I

On the top of the sleeve 82 is secured a top plate 165 (Figs. 1 and 16), to which, is secured a stationary air tube 166, to which is connected from any suitable source means for supplying air under pressure. Near the bottom this tube is provided with lateral ports which discharge into the hollow head 167, which head revolves on the nut 168. Leading from this head is an elbow pipe 169 which connects into an annular air chamber 170 in the top spider 94. :From this annular air chamber the air is taken for blowing through the pipe 171, which is controlled by a spring-closed valve 172 operated by a bell crank lever 173 operated by a cam formed on the outer face of the cam ring 99 (Figs. 7, 8). The pipe 171 leads down to and connects with the outer end of the blowing head arm, and leads into a passage 174 (Figs. 18, 22 and 24) which is controlled by the blowing valve 125. Thisblowing valve has in it two connected ports 223 and 224, and the forward end of the valve at 175 acts as a shut-off when the valve is retracted When the valve is pushed forward into the position shown in Fig. 24, it connects the port 174 with the port 17 6, through the blowing head.

Above the hollow head167 (Fig. 16)-is a hollow head i 177 held between the nut 178 and the lower end of the per spider and it is piped from there through the pipe 184 which leads to the outer end of the blowing head arm, where it connects With a port 185 (Figs. 18, 22, 24). This port communicates with a passage 186 in the blowing valve 125, which leads to the upper part thereof and terminates in the gas nozzle 187, so that the flame will impinge upon the core or plunger 140 when it is withdrawn, as shown in Fig. 22.

Secured to the lower part of the outer face of the sleeve 179 (Fig. 16), is a ring-shaped nut 188, and journaled thereon is the hollow head 189 having a chamber 190 formed therein. Above this head 189 and connected to and preferably formed integral with the sleeve 179 is the ring-shaped flange 191. This flange 191 forms the upper bearing for the ring 189. Within the flange 191 is the chamber 192, and connecting into this chamber is a pipe 193, which is connected to an airexhausting means, such as a pump or fan. Connecting into the chamber 190 is the elbow-pipe 194 which connects to a vacuum channel 195 in the upper spider 94. From this channel is a pipe connection 196 leading to the outer end of the blowing head arm (Fig. 28). In this pipe is a spring-closed valve 197 (Fig. 8' adapted to be opened by a bell crank 198, to which is connected the connecting rod 199, which is operated by the lever 200 bearing against and operated by a cam on the cam ring 99. The pipe 196 (Fig. 28) connects into a chamber 201 formed in the outer end of the bl wing head arm (which, for convenience of description. 1 call the blowing head), which passage communicates with the annular chamber 202. Centrally of this chamber is a ring 203, to which is secured the bushing 204, detachably secured in position as shown. This bushing 204 has a tapering opening 176 through it, and in this tapering opening the plunger 140 is adapted to be projected and withdrawn. The lower end of the bushing 204 is provided with a circular inclined flange 205, and the neck mold sections are provided with complementary grooves to engage therewith.

In the top of the chamber 202 (Figs. 18 and 28) are ports 206, which connect into an annular passage 207 (Fig. 28) formed in the shank of the plunger (Fig. 29).

It is obvious from the description given that the air drawn out through the pipe 196 will be drawn from the chamber 202 through the ports 206 from the passage 207, opening 176 and from the interior of the blank mold, when the sections are close together, while gathering, as shown in Fig. 28. From the chamber 202 there are ports 208 (Figs. 28, 36 and 37), which extend through the neck mold and communicate with vertical passages 209 between the meeting faces of the section of the blank mold (Fig. 22) so as to prevent the ingress of air through the joint between the two sections. This feature is shown in previous patents and is no part of my present invention and therefore I do not deem it necessary to more fully describe it. 7

As previously described, the levers or arms 101, which carry the sections of the blank mold, are hollow, having a passage 210 therethrough. Between the blank mold sections and the arms to which they are secured by the vertical bolts 211, there is a space or passage 212, through which the air will blow upon blank molds, to cool the same. The air for this cooling purpose is supplied from the base of the machine through the pipe 81 (Figs. 1 and 3), the pipe 80, the sleeve 66 and the hollow base ring 64. The top of the base ring 64 (Fig. 4) is provided with ports 213 which communicate with corresponding ports in the lower spider 84, in which there is a chamber 214. This chamber has the passages 215 (Fig. 25) which communicate through the ports 216 with the passage 217 in the pedestal 92 (Fig. 7), and thence into a passage 218 formed in the lateral projections 104 of the blowing head'arm 103 (Figs. 7, 18). On the under side of the lateral extension 104 are the ports 219, and in the'upper side of the arm 101 are the ports 220 shown in dotted lines in Fig. 18, which, when the molds are open, will register with the ports 219, so that the air may fiow into the chambers 210 in the mold-supporting arms or levers, and flow around these molds as shown at the left, Fig. 18. When the mofd is closed, the ports 220 will be moved out of registration with the ports 219, and the air will be shut off from the chamber 210, as shown at the right, Fig. 18.

blank mold and neck mold there is ablowing mold, which is shown in Figs. 1, 7, 8, 22, 25. The

1 frame 233 .is' pivoted on the horizontal trunuions 234, -which are secured in the two curved brackets 235,

blowing mold sections 230 are pivoted together on the pin 231, which is secured in the hollow bracket232,

detachably secured to the hinged frame 233. This Figs. 25 and 27,-which in are secured to the lower spider 84. The frame 233 is bifurcated as shown, and the furcations are hollow,- and the passages 236 therethrough are adapted to register 'in one position of the parts(Fig. 27) with the passages 237 in the brackets 235, which in turn communicate with the passages 238 formed-inthe lower spider 84, and which, as beforedescribed; communicate with a source of air under pressureflsupplied through the pipe 81. When the frame 233 is in its horizontal position, the passages 238,

, cated and the furcations 242 extend horizontally, and

have at. their outer ends the ports 243, which are connected to the passages 244 through the bracket 232 and; communicate with the passages through the frame,

so thatair will be delivered throughthese ports 243, as shown in Fig. 22, upon the bottom of the blank mold sections, when the same are open. Between the furcations 242 of the bracket is a horizontal finger 245 (Fig. 7), atthe end of which is formed the vertical socket 246 (Figs. 7 and 22), in which a' shank 247 is adapted to be secufed, carrying at its upper end thebottom plate 248 -for the blowing mold. This bottom plate is'detachably secured in position in anydesired manner, as. by the detachable spring-securing pin 249 the socket 246, according to securing means for plunger as shown in Fig. 30. I

' The blowing mold and its frame is moved from the vertical position shown in Figs. 7 and 8 to the horizontal, position {shown at the left, Fig. 1, and in rags. 22 and 25, by the track 250, secured to the base ring 64 and supported also on the frame of the carriage at points by the brackets 251. On the under side of the blowing, mold frame 233 is the vertical socket 252, in which slidingly engages the forked bearing 253, carrying at its lower end rollers 254. Interposed between the cross piri 256 and the upper face of the frame 253 is a spring 255, (Fig. 23). By this construction the track, by being properly shaped, will lift the blowing mold with the mold frame, so that the upper face of the blowing ,mold contacts the under face of the neck mold (Fig. 22), and is held tightly in contact therewith by the tension of the spring 255, which likewise takes 0 any slight inequalities in the track 250.

The sections of the blowing molds 230 are opened and closed by the following mechanism Figs. 7, 25):260 are two bent levers pivoted on the pin 261 and slotted at theirouter endsto engage pins 262 on the blowing mold sections. At their inner ends, they are connected together by the toggle levers 263, which are in turn pivoted to the slide block 264. This slide block 264 is supported bya slide rod 265, which passes through an aperture in the block and is guided by the bracket 271 and has a nut 266 at the forward faced the slide block. On the rear face of the slide block and sleeved on the 'rod 265 is a spiral spring 267, bearing at one end against a shoulder on the rod265 and at the' other end against the block 264. The rod 265 is pivotally connected to the push bar 268, which in turn is connected to a slide 269, slidingly secured to the rod 269, having on its upper side the roller wrist 270, engaging in a camway in the under face of the cam ring 95 (Figs. 1, 8), this camway being shaped to give the desired in and out movement to the slide 269 which, through the connections described, will open and close the'molQ sections.. It-will be observed, howeverpthatthe'slide block 264 is operated through the spring.

The parts being thus constructed, their operation is as follows :The machine is moved up to the glass tank by driving the wheels from the motor through the drive connections described, when it will stand in relation to the tank as shown in Fig. 1. The blank molds 'may then be adjusted in proper vertical relation to the glass by the hand wheel 58 rotating on .the shaft and the worm wheels 60. The upper frame work of the machine is rotated constantly by the ver- "tical pinion 8 and the drive connections therefrom This rotation to the gear ring 87 on the lower spider. will be in a horizontal plane and without vertical reciprocation as long as the latches 32 are in the upper position, but when these latches are lowered. by the lever 36 into the path of the shaft 24, the push arms 26 will be reciprocated, and, through the links 27 the gear segments 29 and the rack bars 30, the upper frame of the machine will be reciprocated at intervals during the rotary movement thereof. Just before each blank mold reaches the point in its travel over the glass tank, the parts will be in the position shown in Fig. 28, that is, the blank mold sections and neck mold sections will be closed, and the core or plunger 140 will be lowered through the blowing head and into the neck mold. As the blank mold comes over the glass, the upper frame will be lowered by the mechanism just described, until the lower open end of the blank mold will either come "into close proximity to the glass, or dip therein asshown in Fig. 28; Just at this time, or just prior thereto, the valve 197 will be opened through the connections described, operated by a cam on the ring 99, and the air exhausted from the blank mold, which will cause the molten glass to be sucked up into the blank molds to fill the same, and the upper portion of the blank will be shaped (if a bottle is to be formed,

as in the blank shown) to the shape of the finished bottle, while the core or plunger 140 will make an initial blow opening or cavity in the top of the blank. As the frame travels, the blank mold is raised free from the glass by the raising of the upper frame work, as the frame continues its travel, the roller wrist 144 working in the camway of the ring 98 will rock the shaft 151, which carries the cut-0H knife, and this knife will first be lowered and then moved across beneath the blank mold, severing the glass in the tank from that in the molds, as plainly shown in Fig. 11 As the blank mold with the blank therein reaches the point in its rotation marked station 2 (Fig. 9), or thereabout, the

shaft 151 will be rocked in a reverse direction, with- .dmwi g the knife from beneath the blank, and the b an mold Sections will be opened by the roller wrist '5 11, working in the camway in the cam ring 96, through the connections described. As the blank mold sec- .tions open, ,the air connections through the ports 219, 220, into the arms 101 will be opened and the air will blow onto the blank mold as long at it remains in the I open position are raised by the track 250 to inclose the" blank, asshown in Fig. 12, and the blowing mold sec-- tions are closed about the blank by the roller wrist 27 in the cam ring 95 and the connections to the mold sections, the parts then being in the position shown in Fig. 22. At the time or just before the blowing molds inclose the blank, the air supplyyalve 172 is opened by the lever 173, operated from the cam ring 99, and air admitted throu'gh the connections described and through the blowing head into the top of the article, which is blown to shape as shown in Figs. 14 and-22, As the machine travels, at the proper point in its travel the air valve 172 is shut, the neck ring sections 113 are opened by the roller wrist 124, working in the camway in the ring 97, and the blowing mold opened by the connections from the roller wrist 270, and as it lowers to the vertical position shown in Fig. 8, thefinished article will drop out. The neckmold sections and the blank mold sections are then again closed by the connections described, the blowing valve 125 is withdrawn, the plunger 140 is lowered, and the parts are again put into the position shown for another cessive mold. v
