WORK-HOLDER.

Specification of Letters Patent.

Application filed July 21, 1910.

Patented Jan. 10, 1911. Serial No. 573,139.

To all whom it may concern:

Be it known that I, JAMES A. DE Bonn, a citizen of the United States, residing at Temple, in the county of Bell and State of Texas, have invented a new and useful lVork-Holder, of which the following is a specification.

This invention relates to work holders and its object is to provide a simple device of this character particularly designed for holding doors, window sashes, shutters and the like on edge while being mortised or trimmed.

One of the objects of the present invention is to provide a simple device which can be readily set up at any point and which will firmly hold the object worked and prevent it not only from swinging laterally but also from sliding in the direction of its length.

A further object is to provide a work holder which can be adjusted to work of different sizes and also to properly engage an irregular supporting surface as well as a smooth level surface.

With these and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is a front elevation of the work holder, the same being shown in position upon a door standing on end. Fig. 2 is a side elevation of the holder, the same being shown in position upon a door resting upon one of its longitudinal edges. Fig. 3 is a' plan View of the work engaging head of the holder, the supporting legs being broken away. Fig. 4 is an enlarged section through one of the clamping members carried by the head and showing one means which may be employed for connecting the clamping member to its adjusting screw.

Referring to the figures by characters of reference 1 designates a yoke like head sufficiently large to straddle the edge of a door, window-sash, blind or the like, this head being provided, in one side, with an adjusting screw 2 the inner end of which may, if desired, be provided with a ball 3 seated within a socket 4 formed within a disk 5 constituting a work clamping jaw. The ball 3 may be retained within the socket by means of a holding plate 6 having an opening 7 for the reception of the screw 2. It is of course to be understood that other means may be employed for mounting the jaw for universal movement upon the adjusting screw. The working face of the jaw is preferably provided with a soft covering such as indicated at 8. Another jaw 9 is connected to the opposite portion of the head 1 and is mounted upon a stud 10 extending from said head, the connection between the jaw and stud being preferably similar to the connection between the jaw 5 and screw 2.

A bolt 11 is extended transversely through the head 1 and one end thereof is engaged by a tightening nut 12. A spacing sleeve 13 Y is mounted on the middle portion of the bolt and interposed between this sleeve and each side of the head 1 is a pair of eyes 14 and 15 mounted for rotation upon the bolt 11. Each eye 14 is formed at the upper end of an angular rod 16 constituting the upper member of a side leg 17 the lower member of .this leg being tubular, as shown at 18 and slidably engaging the rod 16, there being any suitable means, such as a set screw 19, for locking the tubular member 18 in any desired position upon the member 16. A curved bit 20 extends from the lower end of the member 18 and is pointed so as to firmly engage the structure on which the work holder is mounted.

The eyes 15 are formed at the upper ends of the upper members 21 of the front legs 22 of the holder. These members 21 are 1n the form of rods slidably mounted within the lower tubular members 23 of the front legs, there being any suitable means, such as set screws 24, for locking the members 21 and 23 together. The lower end of each member 23 has a bit 25 extending therefrom, and which is curved, as shown in Fig. 2, each bit terminating in a point adapted to firmly engage the supporting structure.

In using the device, the jaw 5 is adjusted away from the jaw 9 so as to permit the door or other device to be inserted between the two jaws. Jaw 5 is then adjusted toward the jaw 9 by means of a screw 2 so as to cause the two jaws 5 and 9 to tightly clamp upon the work. The legs 17 and 22 are then swung upon the bolt 11 until they assume desired positions relative to the head and work and each of the legs is then extended or shortened so that the bit carried thereby will properly engage the supporting the legs relative to the head can be 'aried at will, it will be seen that the holder can be adapted for use on irregular and inclined surfaces as well as upon smooth level surfaces.

Various changes can of course be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as defined in the appended claims.

hat is claimed is 1. A device of the class described includ ing a work receiving yoke, work clamping devices carried by the yoke, legs pivotally connected to the yoke, each of said legs being extensible, and means for securing the legs against pivotal movement relative to the yoke said legs being disposed out of alinement said legs being extended beyond the sides of the work within the head.

2. A device of the class described including a work receiving head, means carried thereby for clamping upon the work within the head, longitudinally adjustable legs pivotally connected to the head, means for securing the legs against pivotal movement relative to the head and means for securing each of the legs against longitudinal adjustment, said legs being extended beyond the sides of the work within the head.

8. A device of the class described including a head for receiving work, work clamping devices carried by the head, extensible legs movably connected to the side portions of the head, and support engaging bits carried by the legs certain of said legs being adapted to straddle the engaged work.

4:. A device of the class described including a head, work clamping devices carried thereby, legs pivotally connected to the side portions of the head, each of said legs being adjust-able longitudinally, and a curved bit carried by each leg for engagement with the supporting structure, all of said legs being out of alinement with the held work and certain of said legs being adapted to straddle the work.

5. A device of the class described including a work receiving yoke, work clamping devices carried thereby, a transversely extending pivot device within the yoke, legs pivotally mounted upon said device and out of alinement with the engaged work, certain of said legs being adapted to straddle the work.

6. A device of the class described including a work receiving yoke, work clamping devices carried thereby, a transversely extending pivot device within the yoke, legs pivotally mounted upon said device within the yoke, legs pivotally mounted upon said device and out of alinement with the engaged work, certain of said legs being adapted to staddle the work, and means engaging the pivot device for clamping the legs and the yoke together to hold them against relative movement.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
