June 10, 1941. R, sHANE PRESSURE DEVICE FOR 001mm MACHINE Roms Filed Jan. 2, 1940 Alli 0rd f2. Sane INVENTOR ATTORNEYS Patented June'lO, 1941 PRESSURE DEVICE FOR COATING MACHINE ROLLS Milford R. Shane, Vandergrift, Pa. Application January 2, 1940, Serial No. 312,143
3 Claims.
This application, which is a continuation in part of my prior application, filed May 2, 1938, Serial No. 205,582, discloses an invention that relates to sheet metal coating machines, and its general object is to provide a yieldable pressure device for maintaining the exit rolls of a coating machine in uniform sheet gripping association at all times, so that the dipped sheets will be properly coated and fed from the galvanizing pot of the coating machine.
A further object is to provide a roll pressure device that includes a pair of spring pressed levers pivotally mounted and fulcrumed with respect to the rigging of the galvanizing pot for disposal in bearing and wiping engagement with the bearing collars or bushings on the necks of one of the rolls for urging the same toward its companion roll, and as the levers are pivoted and resiliently mounted, it will be obvious that regardless of the accumulation and solidification of the metal about the bearings and levers, the spreading and rebounding of the rolls, as the sheets enter and leave the same will eliminate any possibility of the levers sticking or adhering to the bearings or rigging, and rendering the levers inoperative, which has been a great source of trouble with pressure devices of machines now in general use. v
Another object is to provide a roll pressure device that can be readily adjusted for maintaining an equal pressure against the bearings of one of the rolls to properly associate the same with its companion roll to bring about evenly coated sheets throughout the entire area thereof.
' A still further object is to provide a ro l pressure device that can be easily and expeditiously installed on machines now in use, is simple in construction, inexpensive to manufacture, and extremely eflicient in operation, use and service.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described. illustrat d in the accompanying drawing and specifically pointed out in the appended claims.
In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:
Figure l is a, top plan view illustrating my roll pressure device applied to the pot rigging of a coating machine.
Figure 2 is a sectional view taken approximately on line 22 of Figure 1, looking in the direction of the arrows.
Figure 3 is a perspective view illustrating one of the pressure levers of my device and its pivotal association with the adjusting rod or shaft therefor.
Figure 4 is a perspective view of one of the roll shoes for the lever.
Referring to the drawing in detail, the letter A indicates the usual roll rigging frame members which are mounted on the top of the metal tank or galvanizing pot B for disposal in bridging relation therewith. The frame members include upper horizontal portions resting upon the top, vertical portions depending into the pot and lower horizontal portions bridging the lower ends of the depending portions, for receiving the coating rolls 0 and D which are provided with necks having secured thereto the usual bear-ing collars or bushings E, the rolls being mounted for rotation through the medium of the bearing collars E, on leveling liner plates F that are superimposed upon the lower horizontal portions of the frame members and the roll D is provided with adjusting liner plates G disposed between the bearing collars thereof and the adjacent frame portions, as clearly shown in Figure 2. The roll D is driven by the power means of the coating machine, in the usual manner, and is geared to its companion roll D which is movable toward and away from the roll D to allow for the free passage of the sheets of metal between the rolls,
it being obvious that the gears permit relative movement of the rolls and particularly movement of the roll C toward and away from the roll D.
All the foregoing structure forms no part of my invention and is illustrated merely for the purpose of explanation and to clearly bring out the advantageous features of my pressure device which includes an elongated base plate I of a length to bridge and rest upon the two long parallel upper horizontal portions of the rigging frame members, as clearly shown in Figure l, and the plate I is fixed to the frame members by screw bolts 2.
Formed on or otherwise secured to the base plate adjacent to the ends thereof are pairs of upright bearing blocks 3 and 4 disposed in parallel relation with respect to each other and the outer blocks 3 are provided with square cornered horizontally disposed bearing openings 5 while the inner blocks 4 are provided with bearing openings 6 that are restricted in rounded formation circumferentially toward the centers thereof to provide a center bearing surface I.
Mounted in the bearing openings of each pair of blocks for longitudinal adjustment is a. rod or shaft 8 and the shafts 8 are of a length to extend a considerable distance beyond the inner bearing blocks 4. The extending ends terminate in forks 9, in the form illustrated and clearly shown in Figure 3. The shafts are round for the major portion of their length, but the end portions thereof that extend into the bearing openings 5 are square cornered to fit the same and from the square cornered portions, th shafts -2 are threaded as at it for a pumose which will be later described. Pivotally secured between the forked portions of the shafts by pivot pins II are the upper ends of pressure levers I2 that are curved longitudinally to engage the vertical portions of the rigging frame, as clearly shown in Figure 2, to be fulcrumed thereon. and the lower ends of the levers have fixed thereto shoe plates ll of a size to extend upon opposite sides of the levers, as
will be obvious upon inspection of Figure 2.
Mounted on the shoe plates II are shoes I in the form of plates, and the shoes I have hooked portions I! for disposal over the upper ends of the plates [3 for holding the shoes inv face to face relation with the plates. By that construction, it will be obvious thatv the shoes can be readily applied and removed with respect to the plates It, so that the shoes can be renewed from time to time as they become worn.
I preferably provide the levers with apertured ears IS, in order to facilitate changing the shoes, as the levers must be removed for that purpose, they being readily detachable from the forked portions as the pivot .pins H are provided with collars or bushings E of the roll 0 slightly above the transverse centers of the necks, as clearly shown in Figure 2, for holding the roll C properly associated with its companion roll D.
In order to hold the levers yieldably associated with respect to the roll C, and for adjusting the same accordingly, I provide coil springs II that accuses tend to prevent the shafts from binding. as will be apparent upon inspection of Figure 2.
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to beunderstood that changes maybe made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
What I claim is:
1. A pressure device for the rolls of a metal coating machine, comprising a base mounted on the upper portion of the galvanizing pot rigging of the machine, bearing blocks formed on and rising from the base, shafts mounted for slidable longitudinal movement inthe bearing blocks, levers pivotally connected to, the shafts and fulcrumed on the rigging for rocking movement thereof, plates secured to the levers, wear shoes detachably mounted on the plates and engaged with the bearing collars of the necks of a roll for urging the latter toward its companion roll, springs sleeved on the shafts, and handled abutment means for the springs and threaded on the shafts for adjusting the pressure of the levers with respect to its roll.
, 2. A pressure device for the rolls of a metal coating machine, comprising a base plate mounted on the upper portion of the galvanizing pot rigging of the machine, inner and outer bearing blocks formed on and rising from the base plate and being arranged in pairs, the inner bearing blocks having bearing openings therein restricted toward their centers to provide center bearing surfaces, the outer bearing blocks having square cornered bearing openings therein, shafts mounted for slidable longitudinal movement and being v rounded for a portion of their length with the surround the shafts 8 and have one of their end convolutions engaged with the innerbearing blocks 4, while their opposite convolutions engage adjusting nuts I! in the form of wheels that include gripping means is. The nuts it are threaded on the portions III of the shafts to vary thetension of the springs to bring about the adjustment of the levers with respect to the rol C, through the medium of the shafts.
From the above description and disclosure in the drawing, it, will be obvious that the roll C is yleldably held in uniform association with its companion roll D, so that the rolls will properly coat and feed the.sheets from the pot, and due to .the fact that the levers are pivotally connected to the shafts, and the latter are resiliently mounted, together with the fact that the levers are fulcrumed on the rigging, it will be further obvious that regardless of the accumulation and solidification of the metal about the bearing collars and levers, the spreading and rebounding of the rolls, as the sheets enter and leave the same will prevent any possibility of the levers sticking to the rigging or the shoes to the bearing collars.
The use of the squared ends of the shafts in the square cornered bearing openings 5, is primarily for the purpose to prevent creeping of the device on worn or uneven bearing collars or bushings, while the beveled bearing openings 6 rounded portions mounted in the center bearing openings and the shafts having square cornered portions mounted in the square cornered openings, levers pivotally secured to the shafts and fulcrumed on the rigging, roll associated bearing means on the levers, coil springs sleeved on the shafts and having one of their ends engaged with the inner bearing blocks, and handled abutment means for the opposite ends of the springs and threaded on the shafts for adjusting the pressure of the levers with respect to the roll.
