Description
- This invention relates generally to handheld or cordless tools and, more particular to a non-pneumatic slag scaler for use in removing slag from welding jobs or similar applications. With interchangeable implements and a rechargeable battery, the non-pneumatic scaler provides improved utility and increased convenience over traditional slag scalers.
- Various surfaces often require a level of cleaning or smoothing than can not be accomplished by hand. A scaler is a device that is useful for removing paint, rust, weld slag, or other hard to remove and unattractive residue. Some scalers have a chisel or needle head that is particularly suited for chipping away hardened weld slag. Although assembly effective, for their intended purposes, the existing scalers must be connected to a pneumatic or electric power supply and are thus limited in their range of movement away from the power source. In addition, the existing scalers may be limited by their inability to accommodate multiple interchangeable implements or to selectively facilitate both linear and rotational movement.
- Therefore, it would be desirable to have a non-pneumatic scaler that is handheld and powered by a removable and rechargeable battery. Further, it would be desirable to have a non-pneumatic scaler having interchangeable implements. In addition, it would be desirable to have a non-pneumatic scaler capable of linear or rotational movement and adjustable speeds.
- Accordingly, a non-pneumatic scaler according to the present invention includes a linear motion gearbox and a motor, the motor being in communication with the gearbox for selectively actuating it. An implement may be removably coupled to the linear motion gearbox such that actuation of the linear motion gearbox causes the implement to oscillate. The non-pneumatic scaler includes a housing containing the linear motion gearbox and is situated such that the implement extends partially outside the housing. A rechargeable battery is coupled to the housing for supplying power to the motor. The scaler includes an input trigger for actuating the motor. Another input device is included for varying the rate of oscillation of the implement. One or more light emitting diodes may be mounted to the housing for illuminating an area adjacent to the implement. In addition, the scaler may include a force transmitter that may transfer the force of the motor to cause the implement to rotate. A clutch may be manipulated to allow either the linear motion gearbox or the alternate force transmitter to be selected.
- A wide range of implements may be removably and interchangeably coupled to the scaler housing such that the scaler is useful for many applications. For example, a chisel head or needle head are useful for removing weld slag whereas an aluminum oxide preparation disc may be attached in order to grind down light welds or to prepare surfaces for painting. Star Brite pads may also be used with the non-pneumatic scaler for paint and rust removal, bead sanding, removal of auto body scuffing, and paint preparation. Carbide burs and wire brushes are also attachable for use with the non-pneumatic scaler for a multitude of cleaning or smoothing applications.
- Therefore, a general object of this invention is to provide a non-pneumatic scaler for preparing or cleaning a surface of rust, paint, weld slag, or the like.
- Another object of this invention is to provide a non-pneumatic scaler, as aforesaid, having an electric motor and linear motion gearbox powered by a rechargeable battery.
- Still another object of this invention is to provide a non-pneumatic scaler, as aforesaid, having multiple removable and interchangeable implements for a wide variety of applications.
- A further object of this invention is to provide a non-pneumatic scaler, as aforesaid, that is lightweight and easy to use.
- A still further object of this invention is to provide a non-pneumatic scaler, as aforesaid, having lights for illuminating a work area.
- Other objects and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, embodiments of this invention.

FIG. 5 is a block diagram of a non-pneumatic scaler according to another embodiment of the present invention. - A
scaler 100 according to the present invention will now be described in detail with reference toFIGS. 1 through 5 of the accompanying drawings. More particularly, according to the current invention, anon-pneumatic scaler 100 includes a linear motion gearbox 110 (FIG. 3 b). - As shown in
FIG. 3 b, amotor 120 is in communication with thelinear motion gearbox 110 to selectively actuate thelinear motion gearbox 110. An implement 130 (i.e., a scaler head) is operatively coupled to the linear motion gearbox 110 (e.g., by aquick release member 112 or another suitable fastener) so that actuation of thelinear motion gearbox 110 causes theimplement 130 to oscillate.FIG. 4 shows oneimplement 130 that is a chisel head 132 and anotherimplement 130 that is aneedle head 134. Though not shown, otherappropriate implements 130 include, for example, a preparation grinding disc, a star-brite pad, a wire brush, and a bur. While theimplement 130 is preferably removably coupled to thelinear motion gearbox 110, it may alternately be permanently affixed thereto. Ahousing 140 may contain thelinear motion gearbox 110 and themotor 120, as shown inFIG. 3 b, and theimplement 130 must be at least partially outside thehousing 140. Thehousing 140 may include arubber handle 142 to dampen the force imparted to the user from using thescaler 100. It should be understood that thehousing 140 may also include a handle having a pistol grip configuration such that thescaler 100 may be used in the manner of, say, a drill or similar tool. - The
scaler 100 may include means for powering themotor 120, such as abattery 150 in electrical communication with themotor 120. More particularly, thebattery 150 may be a rechargeable battery removably coupled to the housing 140 (FIG. 3 b). In addition, means for actuating themotor 120, such as an input trigger 155 (FIGS. 1 and 2 ), may be included. As shown inFIGS. 1-3 b and 5, one ormore LED 158 may be in electrical communication with thebattery 150 and coupled to thehousing 140 for selectively providing a lighted environment adjacent theimplement 130. - As shown in
FIGS. 1 through 3 , aninput device 160 may be in communication with themotor 120 or thelinear motion gearbox 110 for varying a rate of oscillation of theimplement 130. -
FIG. 5 shows that thescaler 100 may further include means for selectively rotating theimplement 130. More particularly, analternate force transmitter 170, such as a gear train, may transfer force from themotor 120 to theimplement 130 to rotate theimplement 130. Aninput device 172 and aclutch 175 or another appropriate device may allow either thelinear motion gearbox 110 or thealternate force transmitter 170 to be selected. - In use, a
respective implement 130 may be selected (e.g., depending on the task to be completed) and coupled to thelinear motion gearbox 110 by thequick release member 112. Thebattery 150 may be charged and coupled to thehousing 140, placing thebattery 150 in electrical communication with themotor 120. Theinput trigger 155 may then be used to actuate themotor 120, causing thelinear motion gearbox 110 to oscillate theimplement 130. TheLED 158 may provide a lighted environment adjacent theimplement 130, and therubber handle 142 may dampen the force imparted to the user from theimplement 130 interacting with a work surface. To rotate (instead of oscillate) theimplement 130, the user may utilize theinput device 172, causing theclutch 175 to select thealternate force transmitter 170 instead of thelinear motion gearbox 110. When selected, thealternate force transmitter 170 may rotate theimplement 130 upon actuation of themotor 120 by theinput trigger 155. - It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
