TRANSFER CAR OPERATING MECHANISM Filed Oct. 8, 1947 George Hegel,

Patented May 29, 1951 TRANSFER CAR OPERATING MECHANISM George W. Hegel, Glenville, N. Y., assignor to General Electric Company, a corporation of New York Application October 8, 1947, Serial No. 778,617
Claims.
My invention relates to a transfer car operating mechanism, more particularly to operating mechanism for a transfer car used in moving furnace cars into and out of furnaces and from one furnace to another, and has for its object simple and reliable mechanism providing a multiplying movement for increasing the distance over which the furnace car is moved so that the furnace car can be moved beyond the transfer car into the furnace.
In carrying out my invention in one form I provide an elongated member or boom secured at one end to a carriage mounted on the transfer car for movement transversely of the transfer car. On each end of the boom I provide a pulley, together with a cable extending around the pulleys and having its ends secured to opposite sides of the transfer car. In the operation of the device the furnace car is attached to the cable and thereafter the carriage is moved to the opposite side of the transfer car. The carriage moves with it the furnace car and, at the same time, the cable moves along the elongated member so as to give the furnace car a movement in addition to that provided by the movement of the carriage itseif.
For a more complete understanding of my invention, reference should be had to the accompanying drawing, Fig. 1 of which is a fragmentary elevation View showing transfer car operating mechanism embodying my invention, while l Fig. 2 is a view mainly in section showing the apparatus of Fig. 1.
Referring to the drawing, I have shown my invention in one form as applied to a transfer car I mounted for movement on a track 2 in front of a plurality of furnaces, three of which, 9, 4, andV 5 are shown. This transfer car is used to move the furnace cars G, only one of which is shown, forming the bottom Walls cf the furnace into and out of the furnaces and to desired positions along the track 2 for the loading of the charge to be heated prior to the heating operation and the disposal of the heated charge after it has been heated.
My invention has particular application to mechanism for moving the furnace car S from the transfer car to a heating position in the furnace and from the furnace on to the transfer car and, more particularly, the provision of means for moving the furnace car a desired distance after it has been moved off the transfer car I,
In one form of my invention I provide an elongated member or boom 'I on the transfer car I, which member is mounted at one end, the lefthand end as seen in Fig. 2, on a carriage '64 movable in a predetermined straight path on a track 9 extending crosswise of the car I substantially midway of the length of the car. As shown, the boom 1 is secured to the carriage by means of posts I0 and II so that it is horizontal and extends transversely of the car I and parallel with the track 9, just above the top of the car. For the purpose of providing a multiplying movement, I provide a cable I2, such as a wire, rope, chain, etc., which extends around pulleys I3 and I4 mounted on opposite ends of the boom I with lengths I3 and I4 extending from each pulley back toward the opposite end of the boom and crossing each other, the ends of the cable being secured by suitable means to opposite or more remote sides of the transfer car at the points I5 and I6. A suitable latching projection or knob II is provided on the upper length of the cable I2 extending between the pulleys near its left-hand end adjacent the carriage when the carriage, as seen in Fig. 2, is in its left-hand retracted position, by means of which knob I'I a furnace car may be secured to the cable. As shown in Fig. 2 the furnace car is provided at its left-hand end with a vertically movable latch. I8 which may be lifted bymeans of av lever I9 and which is provided with projectionsembracng the knob I'I.
The carriage 8 may be moved on the track 9 to move the car 6 into the furnace 4 by means of an electric motor 20, usually provided with a brake to stop and hold the carriage at a desired position, which is connected to drive a sprocket gear 2l with which engages a chain 22 passing around a second sprocket wheel 23 on the opposite side of the transfer car and having its ends secured to the carriage B through suitable shock-absorbing springs 24 and 25. As the carriage 8 is moved toward the right hand from the position shown' in Fig. 1 across the car I to its opposite side, the marriage moves withit the boom 'I whereby the furnace car 6 is moved toward the right hand on a pair of rails 26 forming a track mounted on top of the car I. At 'the same time the cable I2 is caused to move over the pulleys I3 and IlI by reason of the fact that the ends of the cable are secured to the opposite side of the car I. It will be understood that when the boom is moving. toward the right hand, as seen in Fig. 2, the cable moves with reference to the boom, likewise toward the right hand, as well as moving in the s ame direction with the boom. As a result of this multiplying action, the knob I'I is given a movement which is twice the movement of the carriage 8 whereby the knob is moved to the righthand end of the boom and the furnace car 6 is moved beyond the transfer car I into furnace 4. This is indicated by the position of the knob I'I relative to the boom after the furnace car has been moved into the furnace, as shown by dash and dot lines in Fig. 2.
When it is desired to remove a car from a furnace, the boom I is moved underneath the car until the knob II comes under ythe. latch I8. The latch is then lowered and the boom moved back over the transfer car whereby the furnace car is moved on the transfer car as shown in Fig. 2. As shown, the charge carried by-the furnacecar a cylindrical steel billet 21.
As shown in Fig. 2, the .boom 'I` somewhat shorter than the width of the transfer car I -so that when the carriage 8 is in its left-hand retracted position, the ends of thehoom are within the side boundaries of the transfer car. This permits the free movement of the transfer car'along the track 2 either with or without a furnace car 6.
What I claim as new and desire to secure by Letters Patent of the- United `States is:
