J. J. M BRIDE AUTOMATIC SCALE REMOVER Filed Aug. 14, 1943 INVENTOR ATTORN EY Patented Apr. 5, 1949 UNITED STATES NT OFFICE.
AUTOMATIC SCALE REMOVER Application August 14, 1943, Serial No. 498,720
3 Claims.
This invention relates to scale removers in general and in particular to scale removers of the automatic type for use in connection with metal working rolls.
In all working of hot metal considerable scale is encountered and it is necessary that this scale be removed, particularly where the article being molded, worked or pressure welded is intended for use as a container for materials which must remain uncontaminated. It is an object, therefore,
of the present invention to provide a scale remover of the automatic type adapted for use with a pres sure welding machine,
A further object of the invention is the provision of a scale remover automatically swung into position by pressure of the rolls on the material being worked.
A still further object of the invention is the provision of a scale remover automatically brought into position by movement of one of the rolls in its bearings.
These and other objects of the invention will be apparent to persons skilled in the art from a study of the following description and accompanying drawings, in which Fig. 1 is an elevational view of the improved welder with the automatic descaler applied thereto;
Fig. 2 is an enlarged elevatio-nal view of the improved scale remover;
Fig. 3 is an end view of the device, and
Fig. 4 is an elevational view similar to Fig. 2 but showing the position of the parts when the scale remover is out of contact with the work.
Referring now to the drawings in detail, it will be seen that the welding machine M is formed with an upper jaw 2 and a lower jaw 4 so formed as to provide a relatively long and narrow gap therebetween for reception of the work W. As clearly shown in Fig. 1 the upper jaw 2 carries at its extremity a roller 6 rotatably mounted on an axle 8 which in turn is carried by a vertical reciprocable member Hi. The upper end of the reciprocating member is provided with a piston l 2 working in a cylinder l4 supplied by a fluid under pressure through line [6. A spring 18 surrounds the reciprocating member or piston rod and is of sufficient strength to lift the entire assembly, thereby normally holding the pressure roller 6 in a lifted position. Immediately beneath the pressure roller 6 is a econd pressure roller 20 carried at the outer end of the lower jaw 4. This lower pressure roller is mounted upon an axle 22 carried in bearings 24, which bearings are vertically elongated as at 26 and clearly shown in Figs.
LIA 2 and 4. The construction just described is of more or less conventional form with the exception of the elongated bearings for the lower pressure roller.
In order to apply the automatic scale remover to the Welding machine the lower arm 4 is drilled and tapped to receive pivot bolts 30 located outwardly of the axle Z2. Pivotally mounted on pivots 30 are side arms 32 formed adjacent the pivotal mount with openings 34 for reception of the ends of axle 22. Adjacent these openings spring seats 36 are formed on the side arms and buttressed to the side arms by ribs 38. In order to clear the lower jaw 4- the side arms are offset inwardly as at 40, then extended outwardly as at 42 to provide supports for a descaling brush 44. This brush is carried on a rod 46 extending through the ends 42 of the side arms and locked in position against rotation by pins 48 extending through the rod and through slots 50 formed in the end portions 42. In this manner by removal of the pins the brush holding rod may be turned and pins reinserted to bring a new portion of the brush 44 into position for contact with the work.
It is obvious that this brush is only one form of a tool for removing scale from the work and that Various other forms of tools such as scrapers, fluted rollers, etc., may be substituted for the stationary brush shown. Immediately beneath the bearings for axle 22 bracket members 60 are secured to the jaw 4 by bolts 62. Each of the brackets is formed with a spring seat 64 buttressed to the securing portion of the bracket by ribs 66. Springs H1 are interposed between and bear upon spring seats 36 and 64 and these springs are of sufficient strength as to normally lift the pressure roller 25) together with its axle and hold the same at the upper end of the elongated bearings 24.
The operation of the device is as follow and assuming the parts in the unloaded position which they assume and as shown in Fig. 4: The heated work W is placed upon the pressure roller 20 and fluid under pressure admitted to cylinder 14, thus forcing the top or movable pressure roller 6 downwardly onto the work. This pressure which is suiiicient to roll the heated work metal will force the lower or supporting roller 20 downwardly in its elongated bearings 24'. Downward movement of the supporting roller, together with its axle, will cause rotation of the side arms about the pivots 30 compressing springs l9 and bringing the brush or scraping tool 44 into bearing with the work as clearly shown in Fig. 2. Relative motion between the machine and work will cause the scraping tool or brush 44 to remove the scale from the work before the work passes through the rollers B and 20 thereby preventing the rolling of scale into the metal on the interior or under side of the work as shown in Fig. 2. Upon removal of fluid pressure from cylinder [4 the spring l8 will lift the roller 6 and springs 10 can then lift the supporting roller 20 and rotate the side arms to the position shown in Fig. 4 in which the scraping tool or brush 44 is out of contact with the work.
While the scale remover has been shown and described as applied to a pressure welding machine, it will be obvious that it may be applied to any machine utilizing rollers or pressure devices for working metal. Furthermore, although the descaler has been shown as applied to only the supporting roller thereby descaling only one side of the work, it will be obvious that a similar arrangement can be applied to the top roller supporting frame, thereby descaling both sides of the Work. Although the construction has been describes more or less in detail, it will be likewise envious that various modifications and rearrangement of parts other than those shown and described may be made and all such modifications and rearrangements of parts are contemplated as fall Within the scope of the following claims defining my invention.
What is claimed is:
1. A scale remover for work comprising in combiii"atio'n, a frame, elongated bearings carried by the frame, an axle mounted in said bearings for translational movement, a work supporting roller mounted on said axle, side arms pivotally mounted on said frame adjacent said axle and having portions engaging said axle whereby translational movement of the axle in said elongated bearing will cause swinging movement of the side arms about their pivotal mount, a scale rembving device carried by said side arms and movable therewith into and out of engagement with the work during swinging movement of the 'sfdearms, resilient means urging said axle toward one 'side of said elongated bearings to thereby n'orm'ally hold said scale removing device out of a work supporting roll carried by one axle, a pressure roll carried by the other axle, side arms pivotally mounted on said frame adjacent one axle and having their inner end portions engaging said axle whereby movement of said axle in said elongated bearings will cause swinging movement of said arms on their pivots, a scale removing device carried at the free ends of said arms and movable therewith into and out of engagement with the work with the swinging movement of said arms, said arms being formed with laterally ofiset recesses, spring members having one end portion engaging a portion of the frame and the other end portions received in said recesses to normally urge said scale removing device downwardly and the associated roll upwardly, and power means for moving the pressure roll toward said supporting roll to shift the latter in its bearings against the said springs.
3. A scale remover for work comprising in combination, a frame, spaced pairs of superimposed elongated bearings carried by the frame, an axle shiftably mounted in each pair of elongated bearings for movement towards and from each other, a work supporting roll carried by the lower axle, a pressure roll carried by the upper axle, side arms pivotally mounted on said frame adjacent said lower axle and having portions engaging said axle whereby movement thereof in its elongated bearings will cause swinging movement of said arms on their pivots, a scale removing device carried at the free ends of said arms and movable therewith into and out of engagement with the work during swinging movement of said arms, spring means urging the work supporting roll toward the pressure roll, and power means for moving the pressure roll toward said supporting roll to shift the latter in its bearings against said springs.
