Positioned between tl-'ie shoulder V.27 and the nut 262is a sleeve llliavingan enlarged "upperfend portion 32. The'said sleeve Slis kpositioned Within the bearing portion-110i the supporty l0, the' enlarged yportion 3210i said sleeve resting on the upper end-ot said lil 3 bearing 11 and preventing downward movement of the device, and also providing a swivel connection between the supporting member 10 and the device proper.
A disk 33 is provided with a downwardly projecting hub ortion 34 which lits within the interior of t e tubular member 19. Extending downwardly from said hub is a rod 35. Rods 36 extend downwardly from the disk 33 through bores in the enlarged portion 22 of the tubular member 19 and have their lower ends secured to a collar 37. The said collar loosely surrounds the sleeve 19, and is provided with downwardly diverging sides 38.
The lower end of the tubular member 19 is threaded as at 40 to receive the upper portion of the lower gear housing 41. The lower portion V42 ofsaid gear housingis provided with a central opening 43, and is secured to the upper portion of the housing by means of bolts 44. The upper portion of the gear yhousing is of step formation to provide a plurality of chambers 45, 46 and 47 therewithin. At one side of the upper gear housing 41 is a bea-ring 48 forthe drive shaft 49.` The said drive shaft carries a rigidly mounted gear 50 near its lower end. On each side of the gear are roller bearing members 51 and 52 which are receivedr by pockets 53 and 54 of the housing. The gear 50 meshes with a larger gear 55 which hasan interiorly threaded cent-ral bore 56 .within which the ladle holding rod 21 is threaded. The toothed portion of the gear 55 extends downwardly below the lower face of the gear, as at 57. The central portion of the gearis stamped upwardly, as at 58, to form an annular recess 58 surrounding the hub 59 of the gear, the latter extending both above and below the upwardly stamped portion 58.
' The lower ortion of the gear housing 42 is rovided wlth an upwardly extending annu ar portion 60. A roller bearing 61 is positioned within said ring and between the same and the hub 59 of the gear 55. Another roller bearing 62 surrounds the upper portion of the hub 59. An inverted cup-shaped member 63, having a central opening 64 and having its inner sides tapering as at 65, is posisioned over'the roller bearing 62 to hold the same in place. A washer 63 is positioned above said cup-shaped member. Bolts 66, extending from the upper surface of the upper portion 41 of the gear housing, extend Withln the chamber 45 and bear against the top of the washer 63. By turning said bolts the cup-shaped member may be forced downwardlyto adjust the amount of friction between its tapering sides and the roller bearwhich adriving motor 68 is supported. Thek said driving motor has a downwardly extending drive shaft 69, which is connected by means of a coupling portion 70 with the drive shaft 49 extending upwardly from the gear v housing.
Threaded on the tubular member 19, above the gear housing, is a bushing 7l, and surrounding the tubular member 19, above said bushing, is a sleeve 72. An arm 73 extends angularlyV upwardly from said sleeve, said arm carrying'a contact box 74 on its upper end. Within said box is a fixed contact 75 and a pivoted movable contact 76, the lower end of said movable contact projecting from the bottom of the box and beingprovided with a wheel 77. An arm 78 has its lower end pivoted to the lower portion of the arm 73 as at 79. Rotatably mounted on an intermediate portion of said arm is a wheel 80. The upper end of the .arm 78 is adapted to engage the wheel 77 of the movable contact member 7 6.
The wheel 80 extends through a slot 81 in the sleeve 72 and in the tubular member 19 and rides within a groove 82 which extends longitudinally of the ladle holding rod. At the upper end of the rod and communicating with said grove is a recess 83 forming a shoulder 84. When the ladle holding rod reaches the limit of its downward movement, the
wheel 8() engages the shoulder 84 and is forced outwardly. This causes the upper end of the arm 78 to engage the wheel 77 and to cause movement of the movable contact 76 to break the connection within the Contact box 74.
A conduit box 85 projects from the tubular f member 19, and has extending downwardly therefrom a pipe 86, the lower end of said pipe carrying a switch box 87. f
A bracket 88 secured to the tubular member 19 carries a contact box 89, said contact box having a fixed contact 90 therewithin and a pivoted movable Contact member 91. latter member has its upper end extending kthrough the top of the box 89 and carries a and through the rods 36 which have their i` klower ends connected to the collar 37.
The said collar is moved upwardly, its tapering side engaging the wheel 92 of the contact The f member 91 and causing the contact within the box 89 to be opened.
l Starter switches 93 and 94 of the usual construction, one being arranged to cause operation in one direction and one being adapted to cause operation in the reverse direction, are
supported from the upper portion of the tubular member 19 by means of a supporting bar 95 which is secured at a central portion to the tubular member 19.
Extending from the lower portion of the support 10 at one end thereof is a Contact .conduit box'85. h
" made betweensaid conduit box 85 and lthe terrazas supportf96 having aplnrality ofbores97 within `which contactmembers 98I are Slidably positioned, said contact fngershaving their inner ends engaging coiled springs 99 in the .A lusual manner. Theouterends of said contact yfingers engage the yring-shaped contacts 29'on the upper end of the sleeve 159.
Qn the lower end of the rod 21 a bail 100 is carriechrand,within-said bai-l alladle 101 is pivotally mounted. y y
The trolley members '.-16 are connected by wires 102 kwith the contact fingers 98.
the trolley thereto. The enlarged upper portion 22l of kthe tubular member .19, is 'formed withgrooveslOS. Within said grooves .wires Y104 are positioned A(-seejFigs. 5 and 7), the
said wires having oneend-in connection with l the contact-rings 29 and having-their other ends extendingdownwardly and connected with the starter box 93. The'st'artergbox 93 is connected bya conduitlO with thefstart-er box 94. Conduits 106 and 107 extend 'from the starter boxes93and 94 tothe conduit box 85. Y Vires 108 extend from the limitswitch vbox 89 to the conduit box 85, and lwires '109.
extend from the limit kswitch box 4 to the Suitable vconnections f are motor 68 byfmeans of a conduit '110, and wires V111 vextend downwardly through the pipe 8,6l Yto the switch box 87 on the lowerend thereof. The said switch box 87-is provided with a button 112 whichis adapted to bring the starter 93 into operation to cause downward movement pof the ladle, and with a buttonV 113 which is adapted-towbring the starter 94 into opera-tion to cause upward movement of the ladle.
' rl'he operation of the device is, as follows: The pouring'deviceA may be moved along the overhead rail 14 to a desired position ad# i jacent the'molds which are/to be poured. The vdevice is then swiveled within the bearing 11 to adesired angle. 'Itis to be noted that this swivelling of the deviceidoes notinrany way interfere with the conducting of the current from the overhead trolley wires, inasmuch as the Contactr rings r29 and fingers 98 have Vbeen provided to permit thisY swivelling. In
Vmoving' the devicel along the overhead rail Aand in swivelling the same, the operator uses the pipe 83 which is conveniently shaped` to 1 provide an operating handle. AThe operator then pressesthe button 112. which, through the starter 93, causes the electric motor 68 to' operate. This causesl rotation of the gear and the larger gear 55; `Als the ladle hold-V ing rodis threaded vwithin the'gear 55, rotation of said gear'causes the'ladle holding rod to Vbe moved downwardly; with the tubu- Ilarmember 19to lower the ladle 101. The said ladleholding rod will be automatically moveddownwardly until the wheel has en- 'lhe c said contact fingers,` which frietionally Aengage the rings 29, cond ucttheelectricity from gagedthefshoulder 84,150 cause separation of the contacts Z6 and 75.A This will automatically stop the motor 68.. Y
After the molds lhave been poured, if itis f desired to raise the ladle, the operator presses, the butt-on 113. This brings the motor68` again into` operation, but ina reverse direction-throughthe reverse starter 94. Accordingly the ladle holding rod 21 is lraised-until its upper end .engages the lowerendr of .theW
