The subject matter described herein relates to a type of vise for holding material that is being cut with a saw, for example, a band saw.
Working with saws, particularly power saws, carries an inherent risk of injury. The risk is increased when cutting a workpiece that is relatively small. For example, on a band saw a user manually slides the material across the band saw table directly into the moving blade, maneuvering the workpiece according to the desired direction of the cut to obtain the desired shape. Such maneuvers can result in the user's hand being pushed dangerously close to the moving blade.
Embodiments described herein are associated with devices that can hold material that is to be cut with a saw, e.g., a power saw such as a band saw.
Therefore, a vise is disclosed. For example, in one embodiment, the disclosed vise includes a base member, a pair of fixed jaws, a pair of moveable jaws, and a handle. The pair of fixed jaws are attached to a first side of the base member and spaced apart defining a first gap therebetween. The handle attached to a second side of the base opposite the first side. The pair of moveable jaws are adjustably connected to the pair of fixed jaws and spaced apart defining a second gap therebetween. A center of the second gap is substantially aligned with a center of the first gap.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate various embodiments of the disclosure. It will be appreciated that the illustrated element boundaries (e.g., boxes, groups of boxes, or other shapes) in the figures represent one embodiment of the boundaries. In some embodiments, one element may be designed as multiple elements or multiple elements may be designed as one element. In some embodiments, an element shown as an internal component of another element may be implemented as an external component and vice versa. Furthermore, elements may not be drawn to scale.
This detailed description relates to vises for holding material to be cut with a saw. Detailed embodiments are disclosed herein, however, it is to be understood that the disclosed embodiments are intended only as examples. Specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the features described herein in virtually any appropriately detailed structure. Further, the terms and phrases used herein are not intended to be limiting but rather to provide an understandable description of possible implementations.
In the specification, reference may be made to the spatial relationships between various components and to the spatial orientation of various aspects of components as the devices are depicted in the attached drawings. However, as will be recognized by those skilled in the art after a complete reading of the present disclosure, the devices, members, apparatuses, etc. described herein may be positioned in any desired orientation. Thus, the use of terms such as “above,” “below,” “upper,” “lower,” or other like terms to describe a spatial relationship between various components or to describe the spatial orientation of aspects of such components should be understood to describe a relative relationship between the components or a spatial orientation of aspects of such components, respectively, as the device described herein may be oriented in any desired direction.
Power saws, such as band saws, rope saws, or circular saws, are commonly used to cut various materials (such as wood or metal) with a blade that moves continuously while the material is pressed into the blade and maneuvered to achieve the desired cut. The material is often guided by hand in order to achieve intricate cuts, however, this practice can result in a user's hands being pushed dangerously close to the blade, which can lead to serious injury.
The handle 120 can be substantially rectangular or substantially cylindrical in shape, but it will be understood that other shapes are possible. The handle 120 can include a crossbar member 125 to provide increased gripping options for a user to control the vise 100. That is, the handle 120 can include an elongated member 120 attached to the base 110 and a crossbar member 125 attached to the elongated member 120.
The base 110, handle 110, and fixed jaws 130a, 130b can be made using any suitable process, including, for example, stamping, bending, and/or cutting. In one or more embodiments the base 110, handle 110, and fixed jaws 130a, 130b can be formed as a single piece. In one or more embodiments the base 110, handle 110, and fixed jaws 130a, 130b can be made of a plurality of separate pieces. The plurality of separate pieces can be joined together in any suitable manner, including, for example, welding, brazing, and/or one or more fasteners.
The fixed jaws 130a, 130b can be substantially rectangular but it will be understood that other shapes are possible, including, for example, substantially triangular, substantially polygonal or irregular. In one embodiment the fixed jaws 130a, 130b are positioned spaced apart, defining a gap between the fixed jaws 130a, 130b to permit an optional entry point for a saw blade having passed through a workpiece held by the vise 100, for example, when a user intends to severe a workpiece completely.
The fixed jaws 130a, 130b are connected to moveable jaws 140a, 140b by bolts 150a, 150b and 160a, 160b. More specifically, moveable jaw 140a is connected to fixed jaw 130a by bolts 150a and 160a while moveable jaw 140b is connected to fixed jaw 130b by bolts 150b and 160b. That is, each member of the pair of moveable jaws 140a, 140b is connected to a respective member of the pair of fixed jaws 130a, 130b by at least a pair of bolts 150a, 150b and 160a, 160b.
The moveable jaws 140a, 140b can be substantially rectangular but it will be understood that other shapes are possible, including, for example, substantially triangular, substantially polygonal or irregular. The moveable jaws 140a, 140b are positioned such that a gap is defined between the moveable jaws 140a, 140b to provide an entry point for a saw blade to cut a workpiece held by the vise 100. In one embodiment the gap between moveable jaws 140a, 140b is smaller than the gap between fixed jaws 130a, 130b.
In one embodiment, bolt 150a passes through a non-threaded through-hole 152a in fixed jaw 130a and through a threaded through-hole 154a in moveable jaw 140a. In this configuration the distance between the moveable jaw 140a and the fixed jaw 130a can be controlled by adjusting the bolt 150a. For example, in one embodiment turning the bolt 150a in clockwise direction pulls the moveable jaw 140a closer to the fixed jaw 130a while turning the bolt 150a in a counter-clockwise direction pushes the moveable jaw 140a farther away from the fixed jaw 130a. Bolt 160a passes through a non-threaded through-hole 162a in moveable jaw 140a and enters a threaded hole 164a in fixed jaw 130a. In this configuration bolt 160a stabilizes moveable jaw 140a. A similar or identical operational relationship exists between fixed jaw 130b, moveable jaw 140b, bolts 150b, 160b, and holes 152b, 154b, 162b, 164b.
In operation a user places a workpiece between moveable jaws 140a, 140b and fixed jaws 130a, 130b, aligning a section of the workpiece that is intended to be cut with the gap defined between the moveable jaws 140a, 140b. The user then tightens the moveable jaws 140a, 140b against the fixed jaws 130a, 130b to secure the workpiece in place. Each of moveable jaws 140a, 140b can be independently adjusted. Thus, the user can secure an irregular shaped workpiece in the vise 100.
With the workpiece secured, the user can grip the handle 120 of the vice 100 and use it to guide the workpiece into the saw (e.g., a band saw) to be cut. If the user desires to completely sever the workpiece, the user can guide workpiece such that the saw blade passes completely through the workpiece and into the gap between the fixed jaws 130a, 130b. If the user instead desires to make a series of intricate cuts, the user can reverse the direction of movement and maneuver the workpiece away from the saw blade. Once the workpiece is removed from the saw blade the user can adjust the position of the workpiece in the vise 100 as required to make any subsequent cuts
Accordingly, the vise 100 provides the user with various benefits. The user can achieve a high degree of control to execute turns, for example, to create sharp angle cuts or follow complex patterns on a relatively small workpiece, without the risk of the user placing a hand in a dangerous position near the saw blade to maintain control of the workpiece. The user can furthermore execute precision cuts on irregular shaped workpieces.
Aspects herein can be embodied in other forms without departing from the spirit or essential attributes thereof. Accordingly, reference should be made to the following claims, rather than to the foregoing specification, as indicating the scope hereof.
