The present invention relates to improvements in bottle conveying and cooling machines, and it more particularly refers to a taking-out and cooling device for use in connection with bottle forming machines, such as the machine shown and described in in prior United States Patent No. 1,648,? 92.

It is an object of the invention to provide an improved device for lifting the bottles or other molded articles from the bottom plate after the mold sections of the forming machine have opened, and conveying such molded articles to the conveyer or other appropriate destination.

It is a further object of the invention to provide, in conjunction with an improved taking-out device, a cooling device whereby the bottles may be cooled in transit from the forming machine to the conveyer.

A still further object of the invention re sides in providing an improvedtaking-out and cooling device coordinated with respect to the continuous bottle forming machines and coordinated with the drive mechanism of the machine, whereby the machine and device will be driven synchronously, and whereby the grab jaws of the device will be timed with reference to the molds of the machine.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure 1 is a side elevation, with parts broken away and parts shown in section of 40 the improved taking-out device illustrated in conjunction with portions of a forming machine and one end of the conveyor.

Fi ure 2 is a'horizontal section taken on m the line 2-2 in Figure 1, and

Figure 3 is side elevation on an enlarged sca e with parts broken away and parts shown in sec on of the taking-out device and cooling trough.

Referring more particularly to the drawings designates the driving gear'fcr the continuous bottle forming machine 21, such as illustrated and described in my prior patent aforesaid, and 22 represents the bottom plate of the mold in which the bottles 23 or other articles are formed. The mold sectrons are shown in the partially opened and fully opened positions in Figure 2.

The improved taking-out device is adapt ed to be driven from the main machine gear 20 by a pinion 26 keyed on a shaft 27, which also fixedly carries a sprocket 28 engaged with a chain 29. The chain extends through a slot 30 in the base 31 of the improved taking-out device and engages with a second sprocket 32 mounted in the hollow base and keyed upon a vertical shaft- 33 which extends up through a pedestal 3 1 removably or otherwise secured to the base 31.

The shaft 33 extends up above the pedestal 34 and receives fixedly thereon a spider 35 having any appropriate number of arms. The spider rotates about the pedestal with the shaft 33 and is preferably supported upon the ball bearings 36 mounted in conjunction with a flange 37 of the pedestal. .75

At the outer ends of the spider arms are formed tubular bearings 38 open above and below and adapted to slidably receive sleeves 39 which carry on their .lower ends cam wedges 40. This sleeve slidably receives therein a rod 41 which is movable up and down independently of the sleeve 39 and supports at its lower end the grab consisting of the pair of

jaws

42 and 43. These jaws are affixed to levers 44 and i5 pivoted at 46 and 47 to a collar 48 which is pinned or otherwise secured to the lower end of the rod 41. The levers 4A and 45 at their upper ends carry the rollers 49 for cooperation with the cam wedges 40.

At the upper ends of the rods 41, heads or discs 50 are provided, the same being made in one piece with the rods or secured thereto in any appropriate manner. The heads or discs 50 are of greater diameter than the sleeves 239 and are adapted to normally rest upon the upper ends of the spider bearings 38, whereby the spider will normally act to sustain the grab. he bearings 38 are slotted through their lower ends as indicated at 51 to slidably receive the pins projecting from the sleeves 39 and engagedthrough the elongated slots of the :tuating arms '34.

These actuating arms are i'ulcr nned at to the lower portion of the. spider arms and they carry downwardly prciecting parts 56 carrying rollers 57 for engaging a stationary cam 58 adjustably mounted upon the pedestal 34.

The conveyor on which the glass bottles or other molded articles are delivered is indicated at 59.

As shown in Figures 2 and trough 60 of a substantially semi-c form extends about in the circumferential path taken by the grabs andthe. hot es. trough may be supplied with a cooling medium in any appropriate mann r directed to the bottoms and sides of the articles As shown in Figure the trough consists of inner and outer walls 61 and as, the inner walls being perforated, as indicated at 63, the perforations facing the sides of the bottles. 2. The. trough is further constituted bv a bottom (ihaving perforations or allowing the cooling meeium to play against the bottom of the bott s The bottom (ii and the side walls (ll, v i paced from the outer imperlorate walls and bottom walls (3t; and an internal channel or space is provided of a. substantially U-shape nto which cold air or other a ppropriate medium is introduced rom an appropriate source through a conduit 67.

In the use of the device the spider rotates thus causing the the, of which there nj ay be one or more to revolve about the pedestah and in so doing to intersect the molds and the base plates 22 thereof. The take-outdevice and the molding machine rotatcdn the direction of the arrows shown in Figure The arrangement is such that the

grab aws

42 and 43 will be in a lowered open pos tion when approaching a mold whereby the aws may pass about the. neclr ota bottle 23 held u on a bottom plate 22. Promptly therea ter the grab jaws 42 and will be closed upon the neck of the article 23 to firmly grasp the same and suhscqi ly the grab iaws will be raised, as indicated in. Figure 1, to lift the bottle 23 clear of the bottom plate 22 Thereafter the bottle 23 will be carried about through the cooling trough and to the conveyer 59. The arrangement of the cam 58, as shown Figure 2, is such that when. reaching the conveyer, the grab will be lowered and the

jaws

42 and 43 released after the bottle 23 has been placed upon the conveyer 59. The jaws will then (ortlllllG to rotate in the open position until they envelope the next bottle on the foruiinginachine after which the cycle of operations will be repeated At the low point of the cam 58, as shownto the left in Figure 1. the arm 13 i .lhe i will also he the lower position.

Art-ct the 1101;? bottle on the forming machine is e1 o i the open =12 and lfl. the roller. or will reach a higher pointof the cam 58 thus elevating the pin 5:1 and with it the sleeve 39. The sleeve will raise the wedge block 40 which react upon the rollers 4L9 to close the grab jaws 42 and a3 upon the bottle 23 which reposes upon the bottom plate 22. Thereafter further movement of the spider will cause the roller 57 to move out on a still higher point on the cam, 58, causing the sleeve 39 to move up beyond the bearing as shown to the right. in Figure l. sleeve 39 will engage beneath the head or disc 50 and thus elevate the rod ll and with it the entire g ab thereby raising the bottle from the o om plate :22. As the spider continues to rotate this raised bottle is carried about through the cooling trough and suhscqucntly deposited upon the conveyor. The degree of raising of the bottle can be regu-- lated by the distance between the collar 50 and the end of the slecveilil. It will be noted from Figure 2 that the jaws 4' set at an angle to avoid the iaw coming into contact with the bottle octore closing time This arrangement will also avoid striking the bottle at the time of closing of the same on the conveyor.

T he bottom section of the bottle is usually the heaviest and consequently the hottest when it is removed from the mold in a semiplastic state. The present method is to place this bottle in such state directly on the con.- veyer. There is a considerable lapse of time however, between the taking-cut of the bot tle from the mold and the placing of it on the conveyer. During this time the bottoms are apt to sink down and the sides in like manner. After the bottle is placed on the conveyer, the weight of the whole top section of the bottle will bear down or press against the bottom section which is still hot and. in a semi-plastic state, and consequently the. bottle will lose its original shape. This condition is more noticeable in a large bottle than in a small one.

According to the present invention the improved taking-out device grasps and lifts the bottle by its top section which. is cold and chilled by the time the mold opens. The bottle is slowly picked up from the mold and directly passed throughthe cooling channel or trough. The movement of the bottles through the trough will be relatively slow which will insure a ClllllOClllOttlQ bv the time the bottle is set on the conveyor. The imiroved device enables the operating of the orming machine at a higher speed than consequent y results iii agreatcr production.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is 1. A take-out device for molded articles comprising a rotary support, cam means carried by and movable relatively to said support, and a grab rotating with the support and movable horizontally and vertically.

2. A take-out device for molded articles comprising a rotary support, a grab carried on said support and liftable from the support, and cam means for opening and closin said grab movable relatively to the grab and acting to lift the grab after a predetermined movement of the cam means made to close 7 the grab.

'2 3. A take-out device for molded articles comprising a rotary support, a sleeve slidable in the support and having a cam thereon, means to raise and lower the sleeve as the support rotates, a rod slidably received through i 2 zsa'id sleeve and having a part normally supported by the support but positioned to be engaged and lifted by said sleeve after an initial upward movement of the sleeve, and a grab on the rod placed relatively to the cam to be opened and closed thereby on movement of the rod relatively to the sleeve.
