MACHINE FOR LADLING AND TOURING PURPOSES.

Application filed July 11-, 1927,'Seria1 No. 204,944, and in France April 22, 1927.

The present invention relates to a machine which is adapted for taking up or ladling a substance in a recipient and for transporting the same and then pouring it out at the place of use. The said machine, which may be termed a combined. ladling and pouring apparatus. is so disposed that it may be utilized in all manufacturing plants, irrespectively of the relative positions of the recipient and of the place at which the material is to be poured.

.The said apparatus comprises a main frame. adapted to travel upon rails, upon which is mounted a suitable carriage which is transversally .mova'ble with reference to the rails; uponthe said carriage is disposed a pivoted platform upon which are mounted the several mechanical parts by which the.

ladling and pouring operations are effected.

The ladle which servesto take up the material and to pour it out at the place of utilization is mounted on the end of an arm which is connected with a rotatable shaft disposed in a sleeve; the latter is pivotally mounted on what is termed the pouring axis which is .placed parallel with the shaft of the sleeve and is pivoted to an element designated as the cradle whichis pivotally mounted on a support secured tothe said platform. Due to the inclination thus given to the arm of the ladle, combined with the rotation of the said arm, the ladling operation can be suitably performed.

Compressed air is preferably employed for controlling the various movements of the ladle. so that without requiring the use of reducing gear or like devices, the ladle can be given a very easy motion which obviates all formation of air bubbles in the material when in the pasty state.

The appended diagrammatic drawings show by way. of example an embodiment of the invention consisting of a machine for the ladling of glass in a melting furnace and for pouring it upon the table of a plate glass machine.

Fig. 1 is a side elevational view of the machine, and

Fig. 2 is a partial plan view.

Fig. 3 is a partial side view of themachine Figs. 6 to 10 are diagrammatic views relative to the different movements of the ladle.

The said machine comprises a main frame '1 which is adapted to travel upon the rails 2 in front of the furnace whose outer wall is shown at 3. Upon the said main frame is movable transversally to the rails 2 a carr age 4 upon which is pivotally mounted the circular platform 5. Thecontrol of the motion of the main frame and of-the carriage, as well as the pivotation of the platform is effected by electric means from a control post or.

said platform and contains all the necessary controlling devices and the like, which are operated by a single person, and the latter'is further provided in the cabin with the cocks for the admission and discharge of compressed air which serves-by means which will be further describedto impart all the necessary movements to the ladle; the operator can also "control from the cabin the openmg and closing movements of the furnace for the proper handling of the ladle.

Tothe said latform, and on the side opposite'the cabin, is bolted the supportingbracket 7 which is provided at its base with four screw .jacks with square threads by which the machine may be adjusted accordmg to the respective heights of the melted glass in the furnace and theupper edge of the pouring table of the plate glass machine The bracket 7 is provided with two bearings poacting with the trunnions 9 of a device 10 or cradle which is given. a special shape in accordance with the proper mechanical strength and also to provide for its pivotation, and that. of the parts which. it carries, upon the trunnions 9.

The said cradle supports a sleeve provided with two bearings Whose centre line can be made eccentric with reference to the device 11 when for any reason it is necessary to ad cabin which is mounted on an extension 6 of just the'heght: of the axis of the machine within restricted limits. In the said bear ings is mounted a shaft 12 to which is secured the rod or beam 13 by a tapered socket fit and key, said beam supporting the ladle 14 of elliptical section.

At its end opposite the one to which the beam 13 is secured, the shaft 12 carries a special pinion 15 whose number. of teeth, is determined by the amplitude of the motion, and which carries at its periphery the two.

notches 15 and 15" coacting with a pawl 16.

(Figs. 6-10) which is mounted on the said sleeve, the 180-degree spacing of the said notches determines the extreme positions of,

' cradle 10 and its distance from the shaft 12 somewhat exceeds one-half the smaller axis of the mouth of the ladle, and in this manner the sleeve, the beam and the ladle may be ac tuated by suitable means so as to rotate on the axis of the pouring shaft whose extension is situated near the lip of the ladle. This offers an advantage consisting in the fact that whcn'the ladle is being emptied,

the height of pouring of the glass will remain constant adjacent the pouring lip.

The weight of the Sleeve, the shaft 12, the beam 13 and the ladle 14 is balanced by a counterweight 19 disposed between the cheeks 17. I

To the pouring shaft 18 is keyed a toothed quadrant 20 coacting with a rack 21 attached to the rod of a piston movable in a doubleacting cylinder 22 connected with the cradle and provided with the damping means whose object will be further described.

The compressed air necessary to operate the piston coacting with the said rack is supplied by a compressor 23 which is mounted on the platform 5 and is driven by an clectric ,motor, and the air is stored in two tanks 2 1 placed on either side of the cabin.

Upon the pouring shaft is loosely mounted the gear wheel 25 carrying an even number of teeth and also four notches 25-25" 25-25 on its periphery; thesa-id wheel, whose diameter is double the diameter of the pinion 15, is in gearengagement with the said inion.

In order that the rotation of the ladle on its axis shall co-operate with the pivot-ation .of the cradle 10 on its trunnions 9, the pouring shaft has loosely mounted thereon a strap 26 between whose branches is disposed the wheel 25 and which is provided with a counterweight 27 and a pawl 28 coacting with the notches 25 and 25 (Figs. 6 to 10). Outwardly of the pinion 15 there is disposed upon the shaft 18 a suitably balanced hand wheel 29 for the'hand control of the said shaft in case the compressed air supply should fail. The strap 26, although loose on the shaft 18 is held in a well-deter mined position inasmuch as it is connected with a fixed point of the platform 5 by a link 30. of adjustable length.

The pawl 28 which is so disposed as to transmit the power to the wheel 25, has a suitable shape enabling it to engage in any one' of the four notches of the wheel and the pinion 15 rotates in the clockwise direction, and inversely, i. e. the movement is the contrary of the aforesaid movement of the wheel 25 and the pawl 28.

The pivotation of the cradle and the sleeve on the trunnions 9 for ladling purposes is controlled by the bell-crank lever 31 which is pivotally mounted at 32 between twocheeks 33 secured to the platform 5 below and in the rear of the said cradle; the said lever actuates the cradle by means of the link 3-1 which is engaged between the branches of a fork which is formed on the corresponding end of the lever 31.

The other end of the said lever is attached to a slidable member which is movable horizontally by means of the piston 36 to which it is connected by the rod 37 and which is movable in a compressed air'cylinder 38 which is mounted upon the rotating platform below the said cradle.

For reasons which will be further stated,-

the sleeve may be fastened to the cradle, at

the beginning of the ladling operation, by a fastening device which automatically releases the sleeve from the cradle at the end of the ladling operation, so that the glass may be suitably poured. The said fastening device is controlled by the bell-crank lever 31, and it thus depends upon the motion of the piston 36; for this purpose, the

lever 31 carries a trunnion 39 to which is pivoted the head of a small link 40 which draws with it a rod 41 provided with a ring 42 carrying an arm 43; said rod is disposed horizontally above the cylinder 38 and is supported by the latter and also by two bronze rings whereof one is shown at- 11 in Fig. 3.

The fastening device. itself consists of a round rod -15 carrying at its ends two stout members 46-47 which are mounted thereon and constitute a double clamp; said rod is held parallel with the lateral face. of the cradle 10, in two bearings 48 mounted thereon, and it is held against sliding by the two stop rings 49; it may thus be moved by the fork 50 disposed at its lower part and rotatable thereon under the action of the arm 43 actuated by the lever 31.

In these conditions, the device is fastened when the clamp 46 is disposed at. thelower part and below the cradle, and the clamp 47 engages upon a nib 51 screwed into the sleeve.

port carrying at the middle a trunnion upon which is pivotally' mounted below the middle of its length a rod 53. carrying a counterweight 52; said rod passes through two apertured members whereof one is secured to therod 45.and the second 55 is secured as a'controlling fork to the lower ring through which is inserted the rod 45. The counterweight 52,

which is in the position of equilibrium according to the vertical direction, may also.

be held at two other extreme points depending upon the position of the members 54 and 55.

In short, the arm 43 drives in the first place the fork 50 of the said fastening member and hence the pivoted member o.these two members being mounted on the same ringand the counterweight 52 will be inclined to the right or left according to the case and is thus brought into the vertical position.

The apparatus being thus unbalanced, the counterweight descends and rapidly rotates the fastening member 45, and when it holds the cradle and the nib 51 of the sleeve be; tween itstwo ends, the two bearings 48, after their pivotation, will hold the rod 53 of the counterweight in either of its extreme positions. During this time, the fork is'so disposed that the arm 43 will be released therefrom, but its position is such that for releasing purposes'the said arm may return to its position of contact from the start of the inverse stroke of' the piston, this being necessary to return the ladle to the horizontal position for its removal from the furnace.

The operation of the machine is as follows v To facilitate the description of the functioning, and to determine the relative positions of the several parts during their movements, it will be admitted once for all in the following description that the explanation is given by the operator who is stationed in the cabin and observes the ladle in the direction of the beam 13.

With the machine in the inoperative position as shown in Fig. 6, the ladle. 14 is turned about; the beam 13 and the sleeve 11 are held in the horizontal position since the cradle is maintained in equilibrium on its trunnions 9 by the bell-crank lever 31. In this position, the piston 36 of the compressed air cylinder 38 is at the end of its rear stroke, on the side next the cabin, (Figs. 3, 4 and 5).

If the ladle is placed in the furnace by moving the carriage 4 upon the frame 1, the ladling operation may be commenced by the use of a special cock to supply compressed air upon the rear face of the piston 36; the cradle thus rises by pivoting on the trimnions 9, and the motion continues until the lever 31 has the position shown in dot and dash lines in Fig. 3; the said lever constantly holds the device in the e uilibrated position and all vibration of tlie ladle in the melted glass is thus obviated. During the descent, the ladle is rotated in such manner that its edge makes contact with the glass at an angle of degrees.

During the motion of the piston 36 to the right of Fig. 3, the device for securing the sleeve to the cradle has operated.

The motion of the ladle, which is aresultant motion obtained by the use of a ratchet system for combining the downward motion with the rotation of the ladle, takes place as follows When under the action of the piston 36 starting from the end of the rearward stroke of the cylinder 38 the lever 31 causes the pivotation of the crad1e','the pouring shaft 18, the gear wheel 25 and the strap 26 are controlled with the cradle; but since the strap is held by the link30 it will result that its pawl 28- inasmuch as it is engaged in the notch 25 of the wheel 25-will rotate the latter by 90 degrees on the pouring shaft during the downward motion of the ladle. This rotation takes place in the counter-clockwise direction; the wheel 25 draws with it, butin the contrary direction, the pinion 15 which is keyed to the shaft of the ladle, since in this event the pawl 16 can slide out of the notch 15*. Since the ratio between the diameters of the wheeland pinion is 1/2, when the wheel 25' turns through 90 degrees the-pinion 15 turns through 180 degrees, and the ladle is now completely overturned (Fig. 7 Otherwise stated, starting from the POSI- tion shown in Fig. 6, since the pawl 28 engaged in the notch 25 has rotated the wheel 25, the said notch which was situated on the horizontal axis now comes into the lower position upon the vertical axis. During this time, the pinion 15, which is released from its pawl 16 due to the'direction of rotation, has now turned through 180 degrees and the notch 15 now occupies the place of the notch 15 into which the end of the pawl 16 has now dropped. .VVhen the ladle is inclined so as to dip into the glass, it may happen that due to the greater or less viscosity, of the glass the reaction on the ladle amplified by the, length of the beam 13 may counterbalance the preponderating efleet of the weight of the sleeve 11 on the counterweight 19, so that the pouring device will tend .to become disengaged;

the driving wheel 25 no longer occupies the initial position corresponding to the engage-.

stroke and the lever 31 having the position symmetrical with the one shown in Fig. 3, the ladle is now immersed in the melted bath and will be full of glass; it must now be raised by bringing the piston 36 to. the left of Fig. 3 so as to return the lever 31 to the initial position.

The cradle device carrying the pouring shaft, the wheel 25 and the strap 26 is thus brought into the horizontal position I Since this operation is the contrary of the preceding, the pawl 28 has been released, in the mean time from the notch 25* and has dropped into the next notch 25 situated at 90 degrees and is held therein. Sincethe pinion 15 has not been driven in one direction or the. other by the wheel 25, it will still be held by its pawl 16 situated in the notch 15*, so that'the ladle filled with glass will be held in the horizontal position (Fig. 8), and it may then be removed from the furnace under proper conditions by the backward motion of the carriage 4. In fact, none of the parts can move except by an outside agent. The piston 36 is at the end of its stroke and is held by the air contained in the device; the two gear wheels 15 and 25. are held by their respective pawls 16 and 28 which are maintained in theirnotches; the

machine is now ready for the pouring operation.

For this operation, the piston of the double-actihg cylinder 22 ertaining to the cradle actuates by the rac 21 the toothed quadrant 20 keyed to the pouring shaft 18, drawing with 1t in its rotation the sleeve of the ladle shaft which is connected therewith by the two cheeks 17 To obtain the inverse motion after the pouring, the sleeve starts fromits upper position and comes into its initial position in the cradle by the action of the rack 21, in combination with the action of the damping device provided on the cylinder 22 and consisting for example of a ball which throttles the compressed air outlet.

With the ladle in the horizontal position for its removal, air is admitted into the cylinder 22 by a cock (which is not the same as the cock used for the ladling); by the action of the rack 21 which is secured to the piston, the said quadrant will cause the whereby the pawl 16 will be held in the notch 15 which it already occupied. By an effect of reaction, the wheel 25 is actuted by -the pinion 15 (which is held against'rotation) so that the pawl 28 which is released from the notch 25 will slide and will drop into the notch 25 (Fig. 9). At the end of this movement, since the pawl's 28 and 16 are held in position, one 1n the notch 25 and the other in the notch 15; the ladle is new empty, and it is to be brought into the initial position (with the sleeve placed directly in the cradle and the ladle in the inverted position) and then cooled. j

' Under the action of the rack 21, the sleeve and the shaft return to the initial position by a movement which is contrary to the preceding. The wheel 25 is held in the fixed position by its pawl 28, and due to the reaction of the planetary pinion 15 the latter turns through 180 degrees in the clockwise direction since the pawl 16 is enabled to leavethe notch 15 and to slide into the notch 15*. At the end of this operation, the re spectivepositions of the pawls are as follows: The pawl 28 is held in the notch 25 and the pawl 16 has'returned into the notch 15" (Fig. 10).

This

16' is again engaged in the notches 15 and the pawl 28 has moved from the notch 25, to the notch 25 situated upon the same horizontal diameter, the gear wheel 25 being loose upon the shaft 18; this will have no efiect,.and by referrin to Figs. 6-10 it will be noted that the notches 25?.-25 serve for the intermediate positions, but that at the end or the beginning of a' complete operation, the pawl 28 will always be engaged in the notch 25 or 25. I

Before returning to the furnace to begin another ladling operation, the carriage carrice the ladle towards the place where the movements for emptying the bottom of the ladle are effected asshown in Fig. 10.

-The ladle must now be cooled, and for this purpose, by the roper operation of the carriage and the plat orm, the ladle is placed under a hood provided. with pressure water iac depends upon the length of the link 30 (which is regulated once for all) and upon the distance between its point of rotation upon the strap 26 and the center of the wheel 25.

During the pouring operation, the pivoted link which is thus adjusted will serve as a support or strut by which the whole mechanism will be held in the horizontal position with reference to the axis of pivotation.

The position in space of the trunnion connecting the head of the link 30 with the strap 26 will remain constant, and during the rotation of the said strap, only its pawl 28 which is urged'in one or the other direction may be engaged with or released from the said notches, thus determining the clegre of relative rotation of the gear wheels 25 and 15.

By adding to the machine a second driving wheel similar to 25 and symmetrical with the latter about the main axis, the ladling may be performed at one edge of the ladle and the pouring at the other edge, and this is advantageous from the fact that if air bubbles are produced in the glass during the ladling operation and at the side adjacent the lip, such bubbles will not move forward and will remain at the bottom of the ladle.
