Application March 9, 1956, Serial No. 570,661

1 Claim. (Cl. 144-296) The present invention relates generally to means to hold a door or other workpiece in a position to permit the performance of work thereon by a craftsman. Specifically, the invention has reference to a device falling in this general category, which can serve as a floormounted, horizontally extending stand or support for a workpiece whenever desired or, alternatively, can be disposed in an erect position for the purpose of supporting on edge a door, window frame, or the like being planed. F The edge planing of doors and other large, flat Workpieces is generally accompanied by considerable difiiculty, in view of the difiiculty of holding the workpiece steady, on edge, while the work is being done. The invention has, as one important object, the provision of a door planing jack which is particularly designed to permit the swift clamping of a door or other workpiece thereto, and which, when the door is so clamped, will hold the piece steady, so that it may be edge planed.

Another object of importance is to provide a device of the nature stated which, whenever desired, can be adjusted to a horizontal position, and fixedly secured in place to provide a horizontally extending support for the work.

Still another object of importance is to provide a planing jack or work holder which can be used for various other work being done by a cabinet maker, carpenter, or other craftsman, as for example, as a holder to hold one finished side frame of a cabinet while the other side is being nailed by a cabinet maker.

Still another object is to provide a device as stated which will hold doors of difierent sizes and thicknesses, windows, screens, storm sashes, boards, or any of various other wooden pieces needing edge planing or other work.

Still another object is to provide a device of the nature described that can be carried from place to place with minimum difiiculty, due to its relative lightness and the adaptability of one of its components in providing a handle.

Summarized briefly, the invention includes a fiat base, and extending normally to the plane of the base at one edge of the base is an elongated member recessed to receive an end of a door or similar workpiece. Spaced longitudinally of the member are clamp elements, adapted to bear against the workpiece when the same is engaged in the recess of the device, so that, with the base laid flat against the floor, the workpiece will be supported on edge to permit edge planing or other work to be performed thereon. The base is provided, along the side edge remote from the one having the elongated member, with brackets, which can be secured fixedly to a floor, trestle, or the like when the base is set on edge in a vertical plane. Under these circumstances, the elongated member extends horizontally to provide a support for a workpiece, and on the end of the elongated member remote from the base there is provided an approximately triangular, pivoted yoke which can be swung into a position parallel to the plane of the now vertically dis- Patented Jun 18,. 1957 ice 2 posed base and can be secured to the support surface, so that the base and said yoke or stand cooperate in providing a fixed Support for the elongated member.

Another object of importance is to provide a device of the nature described which can be manufactured at a low cost, will be rugged, and highly versatile.

Other objects will appear from the following description, the claim appended thereto, and from the annexed drawings in which like reference characters designate like parts throughout the several views and wherein:

Figure 1 is a perspective view of a device formed according to the present invention, a door supported thereagainst being shown fragmentarily and in dotted lines;

Figure 2 is a plan sectional view on line 2.2 of Figure 1, the door being shown in dotted lines;

Figure 3 is a sectional view on line 3-3 of Figure 2; and

Figure 4 is a perspective view of the device adjusted for use as a horizontally extending support.

Referring to the drawings in detail, a base 10 is formed as a flat, rectangular piece, and secured by screws or equivalent fastening elements to one longitudinal edge of the base are brackets 12, having outer ends projecting beyond the adjacent ends of the base and formed with openings 14 receiving screws or other fastening elements when the base is to be mounted in the Figure 4 position thereof upon a floor surface or the like.

Fixedly secured to the base'and extending therefrom perpendicularly to the plane of the base is an elongated, relatively narrow bar 16. This is disposed approximately medially between the opposite ends of the base, at the side of the base opposite from that on which the brackets 12 are mounted. The bar has an outer side surface registering with the adjacent longitudinal edge of the base.

The bar 16 is formed, at locations spaced longitudinally thereof, with openings receiving bolts 18. Nuts 20, threaded upon the respective bolts, bear one. against the bar 16 and one against a wider bar 22, Bar 22,- as shown in Figure 2, is substantially wider than the bar 16, the two bars together constituting, when fixedly connected by means of the bolts, an abutment member for a door D or the like. Due to the greater width of the bar 22, there is defined a recess 23 receiving the adjacent end of the door, one face of the door bearing against one wall of the recess and the end edge of the door bearing against the other wall of the recess, said other wall lying in the plane of the adjacent longitudinal edge of the base 10.

It will be seen that the

bars

16, 22 together constitute an elongated work-engaging member, and to fixedly mount said member upon the base 10, the bar 22 has at one end a longitudinal, reduced extension 24 engaging snugly in a laterally opening recess 26 of the base 10 (Figure 4), lag screws 28 or equivalent fastening elements being extended through the extension 24 into the material of the base.

At its free end, the elongated work-engaging member is provided with a combined carrying handle and stand 30 of approximately triangular shape, the apex end of the stand 30 being formed open and being integrally provided with transversely spaced, apertured ears receiving a transversely extending pivot pin 32. At the base of the stand there is provided a centrally disposed opening 34, so that when the elongated work-engaging member is disposed horizontally with the base 10 in a vertical plane as shown in Figure 4, the stand may be turned ninety degrees from the Figure 1 position thereof into a plane paralleling that of the base. Screws or other securing elements may then be extended through the

apertures

14 and 34 of the base and stand respectively, to anchor the device to a suitable supporting surface with the elongated work-engaging member extended horizontally to support boards or other workpieces while work is performed thereon.

When the device is in use as a door planing jack as in Figure 1, it may also be anchored to a supporting surface with base 10 in a horizontal plane, through the provision of an angle bracket 36 apertured for extension of a screw therethrough, the angle bracket having its free end lying substantially in the plane of the top surface of the base 10 as shown in Figure 3. The purpose of this is to permit the brackets 36 to be connected to a horizontal plank or other support when the device is being used out of doors. In other words, the plank, not shown, may support the door out of contact with the ground surface, and the base will abut against one end of the plank in a plane common to that of the plank, with bracket 36 being secured by a screw or the like to the plank itself.

Door clamping means is provided upon the elongated member, and to this end, on one end of the bolt 18 there is provided a radial arm 38, having a threaded opening at its free end receiving a clamping bolt 40 the inner end of which is provided with a swivelled clamping foot, while the outer end has a crank handle 42. The clamping bolts are threadable into the door-receiving recess of the elongated member as shown in Figures 1 and 2, so that when the end of the door is seated in the recess 23, the clamp screws may be turned home against the adjacent face of the door. The door will thus be clampably engaged between the bar member 22 and the respective clamping screws.

The feet of the clamping screws can, of course, be provided with pads, cushions, or the like to prevent damage to the door.

In use of the device, and assuming that a door D is to be planed along its edge, it is merely necessary that the end of the door be inserted in the recess 23 and the clamping screws tightened against the door in the manner previously described. The door will thus be held in a vertical plane, lying on its opposite longitudinal edge. Obviously, the invention can be used in pairs, with one device at each end of the supported door.

When the device is to be carried from place to place, the handle 30 can be used, and further, whenever a horizontally extending support, that Will hold a piece of Work in elevated position above the bench, floor, or other surface is desired, the device is adjusted to the Figure 4 position thereof, again being used, if desired, in pairs. The device under these circumstances becomes, in effect, a small trestle or saw buck.

It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to Which it may be suited. Nor is the invention to be neces sarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claim.

What is claimed is:

A work holding device comprising a flat base; an elongated, work-engaging member rigid with and extending from the base perpendicularly to the plane of the base, said member having a longitudinal recess to receive a workpiece; clamping means carried by said member adapted for engaging a workpiece seated in said recess; and a carrying handle on said member at the end of the member remote from the base, said member being secured to the base at one side of the base, said carrying handle being pivoted to the member for swinging movement about an axis paralleling said side of the base between a first position in which the handle is extended longitudinally of the member and a second position in which said handle is extended in a plane paralleling the plane of the base toward the opposite side of the base, thus to cooperate with the base in providing end supports for said member when the member is horizontally positioned.
