RICHARD H. BROWN A T TORNEYS United States Patent 3,495,795 VISE HOLDER Richard H. Brown, Williamsville, N.Y., assignor to Pivot Punch Corporation, North Tonawanda, N.Y. Filed Dec. 13, 1967, Ser. No. 690,306 Int. Cl. F16m 13/02 US. Cl. 248-221 4 Claims ABSTRACT OF THE DISCLOSURE A bracket for mounting on a cylindrical post (such as a typical cellar ceiling support column and jack device) to accommodate in swivelable relation thereon a shop vise or the like; the bracket being rotatable on and vertically slidable on the mounting post and embodying a position adjustment and locking means featuring an improved jogging release and safety locking action, facilitating manual rearrangements of the elevation and/or radial direction of the bracket.

Background of the invention It is conventional in the mounting of shop vises or the like to clamp them for example upon work benches in home basements; such benches being free-standing on attached legs or secured along a basement room wall, in order to add extra stiffness and support. However, it has been found that vertical pillars or posts may be conveniently utilized to provide support for such Work tools whereby they may be approached from all sides. Thus, the steel or iron pipe type of post typically present in a residence cellar may be employed as a support for such tools since this tye of pillar provides a firm and solid support accessible from all sides.

The object of the present invention is to provide an improved bracket which is adapted to support a working tool in cooperation with a vertical pillar as described hereinabove.

Summary of the invention In the present invention a bracket is provided which is adapted to be mounted on a cylindrical post and having an outwardly extending arm member adapted to accommodate in swivelable relation a shop vise. The bracket being rotatable on and vertically slidable on the mounting post and including a position adjustment and locking means.

The invention is illustrated by way of example by means of the accompanying drawing wherein:

FIG. 1 is a side elevational view (partly in section) of a bracket device of the invention illustrating support of a shop vise on a typical cellar ceiling support post;

FIG. 2 is a sectional view as suggested by line 2-2 of FIG. 1;

FIG. 3 is a fragmentary section taken-as suggested by line 3--3 of FIG. 1;

FIG. 4 is a fragmentary section taken as suggested by line 4-4 of FIG. 2; and

FIG. 5 is a side elevational view of a typical installation of the bracket of the invention, illustrating the versatility of positional adjustment capabilities of the device.

As shown herein, the device of the invention is adapted to be mounted upon any vertical post device such as may typically be set upon the floor 12 of a home basement or cellar (FIG. 5) for support of the ceiling 14 or other above-surface structure of the building. The bracket is shown as mounting thereon a shop vise 15. The bracket of the invention is indicated generally at 20 to comprise essentially an arm portion 22 terminating at one end in an arcuate shaped bearing portion 24 (FIG. 2) which is formed to complement the surface contour of the post 1 3,495,795 Patented Feb. 17, 1970 ice 10. Thus, the bracket is adapted to be releasably clamped to the post 10 as by means of a semi-cylindrical shaped cap member 26; the clamping action being provided by means of a hinge screw as indicated at 28 in cooperation with a lock screw 30. The screw 30 is preferably arranged to be actuated by a manually operable slide handle 32.

At its other end the arm portion 22 is formed as indicated at 34 to mount in rotatable relation thereon the base portion 36 of the vise 15, as by means of a bolt 38. A washer 39 is preferably employed therein as shown at FIGS. 1, 4. Thus, the vise 15 is rotatable about the axis of the bolt 38 so as to permit of any angular adjustments of the vise relative to the outer end of the bracket. A lock bolt 40 adapted to be manually controlled by a slide lever 42 is provided to lock the vise in any adjusted position on the bracket.

It is a particular feature of the present invention that in addition to the basic lock device 32, a supplemental safety lock lever 44 is provided in conjunction with the bracket. The lock member 44 is pivotally mounted on the screw 30 and includes a cam-nose portion 46 (FIGS. 2, 3) adapted to frictionally engage the column 10 when the member 44 is disposed as shown by the solid line showing in FIG. 3. A spring 48 operates to bias the safety lock 44 into holding position the spring being hooked at one end over a pin 49 bridging the space between the arm 22 and cap 26 and at its other end with a heel portion of the lock member 44 as best shown in FIG. 3. However, as also shown therein, the lever 44 may be manually moved into the broken line position thereof so as to release the holding action of the device.

Hence, assuming it is desired to change either the radial direction of extension of the bracket relative to the mounting post or the elevation of the bracket on the post, the lever 32 is initially rotated to release the basic clamp action of the cap member 26. However, the safety lock 44 continues to hold the bracket against movement relative to the post. Therefore, in order to adjust the position of the bracket either radially or vertically relative to the post, the lock lever 44 must be manually released against the action of the spring 48, such as to the position shown by broken lines in FIG. 3. Then, after such adjustment is effected, the lever 44 is released and the lever 32 is tightened to provide a dual locking arrangement.

Therefore, it will be appreciated that the safety lock lever 44 may be used to permit a jogging control of the vertical and/or radial position of the bracket relative to the post 10. For example, if it is desired to lower the bracket on the post 10, the main lock screw 30 is initially released. Then, while the operator substantially supports by hand the weight of the bracket-vise combination, he jogs" the safety lock lever 44 so as to momentarily release its locking action. Thus, the operator may readily guide the bracket-vise combination with one hand to move either vertically or horizontally in any desired direction while continuing the jogging-release action of the lever 44. Then, at any time upon discontinuance of the jogging action the primary lock device 32 may be tightened so as to firmly lock the bracket in the desired position of adjustment. Hence, it will be appreciated that the safety lock lever 44 operates at all times to prevent any accidental falling of the bracket and vise combinanation to the fioor incidental to positional adjustments thereof on the column 10, such as might cause damage to the mechanism and/or injury to the users hands or feet.

It will of course also be appreciated that although only one form of the invention has been illustrated and described in detail hereinabove, it will be understood that various changes may be made therein without departing from the spirit of the invention.
