To all 'whom t may concern.'
Be it known that I, ALBERT T. KELLER, a citizen of the United States, and a resident of Baltimore, in the city of Baltimore and State of Maryland, have made a new and useful Invention in Double Hotbeds, of which the fol- A lowing is a specification.
` provide a bed in which the rods or bars shall his invention relates to t'he steel industry and particularly to hot beds for handling l long slender shapes during the cooling thereof.
An object of this invention is to provide a hot bed which shall, for all practical 'prposes, be perfectly balanced, that is, one in which a load being lifted is in effect counterbalanced by a descending load in another portion of the device. By counterbalancing a load being lifted byone descending the power re uird for the operation of the bed is reduce to a minimum and, as the entire load must be lifted a large number of times during a days operation this cutting down of the required power is an important consideration.
A further Kobject of this' invention is to be maintained in parallelism or Yin other words kept strai ht during their cooling, and this is secure by providing stationary notched skids and lifting bars for'moving the rods or bars from one series of notches to the other in a step bystep manner.
A still further object is theprovision of an apparatus which shall attain the-desired results in a simple an eicient manner without the use of parts liable tobecome worn and 'to require frequent replacement.
These as well as other objects which will readily be understood by those in this art I attain by means of the apparatus described in the specification and illustrated in the drawings accompanying the same and forming a part of this application and throughout which similar elements are denoted by like characters.
In the drawings, Figure 1 is an end elevation of a hot bed constructed in accordance with this invention, Fig. 2 is a plan view thereof, Fig. 3 is a section taken on line 3-3 of Fig. l and Fig. 4 is a fragmentary end elevationof a portion of the feeding-in means for discharging the bars onto the hot bed. The hot bed of this invention may be termed a double hot bed, that is the feeding-in rolls are located at ,the centerof the bed and the material is discharged therefrom, in opposite directions and is progresslvely moved in a step by step manner from thev central feeding-in rolls to feeding-out,
rolls located on opposite sides of the feeding- 1n rolls. The feeding-in rolls, the feedingout rolls and the As illustrated in the drawings, it will be seen that on suitable end supports 10, 10 and center support. 11 I mount transverse girders 12 and 13 on one side of Lthe center and 12 and 13l on the opposite side. These girders serve to support the longitudinal stationary skids 14 and 14, respectively. Skids 14 and 14' in their upper surfaces are provided with notches 15 and 15*Il and one end of each stationary skid is located in proximity to the feeding-in rolls 16 and 16* while the other end of each skid is located in proximity to the discharge skids 17 and 17 and the feeding- lout rolls 18 and 18.
Alternating with the stationary skids are lifting bars 19 and 19, respectively, mounted on girders 20-21 and 20u-21"L which extend from end to end ofthe bed. Girders 20 and 21 are connected by links 22 and 23 to the outward extending arms of 'bell are connected by links 22 and 23a to the y outward extending arms of bell cranks 24Il and 25. The downward extending arms of bell cranks 24 and 25 are connected by .coupling rods 26 and pitmen 27 while the corresponding arms of bell cranks 24 and 25'* are connected by rods 26 and pitman 27. The inner ends of the pitmen are con-4 nected to a crank 28 on a shaft 29 through which motion is imparted by suitable slowdown gearing from a motor 30. The inner girders 21 and 2-1a are provided with brackl ets 31 and 31* which are connected by pitmen 32 and 32' to a crank 33 on .shaft 34 by |bed proper are duplicatedl on opposlte sides of the center of the appara- Vtus and are identical. l
soi
which Vmotion is imparted through slowdown gearing by means of motor 30.
The rods such as shown at 35,3Fig. 1, are received by the feeding-in rolls 16 and 16 and are discharged in opposite directions into the first notches of the stationary skids by 'means' of levers 36 and 36L to whichv motion is imparted by yoke 37 actuated bycam 38 mounted on shaft 34.
' liftin are shown in their lowermost position while bars '19 are shown in their t"op or raise position. As operation of cranks 28 and 33 is continued lifting bars 19` will move laterally and deposit rods `35 in the notches of stationary skids 14* at the same time lifting bars 19 rise and lift the rods from the notches 15 of stationary skids 14 and carry them forward to thenext notch `or away from shaft 34. The movement of the rods 35 progress in a step by step manner from the feeding-in rolls to the feedin -out rolls, the lifting bars on one side o the feeding-in rolls ascending while those on the other side are descending and since-these are interconnected by the links l and levers the vWeight of the moving partsv and the load is practically balanced.
Having thus described my invention what I claim is 1. In a hot bed, feeding-in means, a plurality of fixed longitudinal skids located on opposite sides of'said means and pro- 4vided with notches in` their upper surfaces,
lifting bars paralleling said skids, Vmeans for su porting the lifting bars on one side of said feeding-in means in balanced relation to those on the other side, and means for lc)ausing up and down motion of said lifting ars.
3. In a double hot bed, centrally located feeding-in rolls, mechanisms for transferrin material in opposite directions from sai feeding-in rolls, and means for connecting the transfer mechanism on one side of said feeding-in rolls with the transfer mechanism on the other side in such manner 'that the transfer mechanisms operate in balanced relation toeach other. i
4. In a double hot bed, centrally located feeding-in rolls, feeding-out rolls located -on op osite sides of said feeding-in rolls, mechamsm for transferrin material in opposite directions from said ceding-in rolls to said feeding-out rolls, and means for connecting the transfer mechanism on one side" of'said feeding-in rolls with the transfer mechanism on the other side in such manner that the transfer mechanisms operate in balanced relation. f
' In testimony whereof, I have hereunto subscribed my name this 9th day-'of March,
ALBERT T. KELLER.
