Application March 22, 1940, Serial No. 325,303 2 Claims. (01. 81-41) This invention relates to new and useful improvements in a bench vise.

More specifically, the invention proposes the construction of a bench vise characterized by a bench clamp adapted to be mounted upon a bench and provided with a vise universally mounted thereon and arranged in a manner to assume any desired position with relation to the bench top.

Still further it is proposed to provide the bench clamp with the zone of a spherical recess within which a spherically shaped member formed on said vise is adapted to be engaged.

Still further it is proposed to provide a means upon the bench clamp for holding said spherical shaped member in various fixed positions within said spherical recess in a manner to hold the bench clamp in various pivoted positions.

Still further it is proposed to slidably mount the vise upon said bench clamp in a manner to permit the same to be moved to various fixed adjusted forward and rearward positions upon the top of said clamp.

Still further it is proposed to provide a means for permitting the vise to be held in various adjusted elevated positions with relation to said clamp in a manner to permit the vise to be elevated with relation to the top of the bench when desired.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

The bench vise, according to this invention, in-

This U-shaped bench clamp Ill is adapted to be engaged upon the edge of a bench with the inside face of its top arm resting upon the top face of the bench. The other arm of the bench clamp W has a screw ll threadedly engaged therethrough. The inner end of the screw II is provided with a turnably mounted plate l2 which is adapted to engage the bottom face of the bench. The other end of the screw H is provided with a radially extending handle l3 which is adapted to be used for turning the screw H to cause the plate l2 to bear rigidly against the bottom face of the bench and hold the bench clamp ill in position thereon.

The bench clamp Ill has the top of its body formed with a zone of spherical recess H which is open at the top and at the front. A vise I5 is provided for engagement upon the bench clamp In. This vise l5 comprises a fixed jaw l5 having a jaw element 15". A movable jaw l5 has a jaw element l5 which is adapted to cooperate with the jaw element 15 for securely holding a piece of work in position. The movable jaw [5 is moved towards and away from the fixed jaw l5 by means of a screw It. This screw is merely rotatively extended through the movable jaw l5 and is threadedly engaged into A handle I1 is provided for permitting the screw l6 to be rotated. Several guide posts 18 extend from the movable jaw l5 and slidably engage into complementary openings formed in the fixed jaw l5 for holding the movable jaw l5 in alignment with the fixed jaw I5. The bottom of the vise I5 is formed with a substantially spherical member l9 which engages into the recess. l4 and which extends from the open top thereof: The spherical member [9 may be made detachable from the vise or be integral therewith.

- A means is provided for holding the spherical member IS in various fixed turned positions within the spherical recess II for holding the vise IS in various pivoted positions with relation to the bench clamp l0. This means comprises a band 20 extended across the open side of the recess l4 and which engages against the side of the spherical member 19. One end of the band 20 is securely held in position. For accomplishing this secure mounting of the end of the band 20, a bolt 2| is engaged through the end of the band 20 and is threadedly engaged into a complementary boss 22 formed upon the body of the bench clamp 10. The other end of the cludes a bench clamp ll) of substantially U-shape.

band 20 has a screw 23 freely engaged therethrough and which engages a complementary boss 24 formed upon the body of the bench clamp ID.

The screw 23 is provided with an enlarged head 23 which is adapted to abut the face of the band 20 for moving the same towards the spherical member l9 when the screw 23 is threadedly engaged into the boss 24. The head 23 also has a handle 25 by which the screw 23 is adapted to be rotated.

A means is also provided for indicating when the vise I5 is arranged exactly horizontal and exactly perpendicular to the bench top to which the bench vise has been applied. This means comprises an alignment marker 26 formed upon the rear portion of the spherical member l9. This alignment marker comprises a vertical line 26 and a horizontal line 26 which cross each other. The adjacent edge of the body of the bench vise I is provided with a horizontal cutout 21 and a downwardly extending marker 28 which extends downwards exactly at right angles to the edge of the cut-out 21. When the horizontal line 26 of the marker 26 is arranged exactly parallel to the edge of the cut-out 21 and lays immediately adjacent thereto, the bench vise will be arranged substantially parallel to the bench top. Similarly, when the ends of thevertical marker 26 and the marker 28 are arranged ex actly in end alignment the bench vise will be extended exactly perpendicular to the bench top.

The angular position of the vise may also be determined approximately by the angle indicating plate 29 located on the top face of the clamp In which is in the vicinity of the lower end of a pointer 29' projecting downwardly from the adjustable vise l5.

The operation of this form of the invention is as follows:

To adjust the position of the bench vise to assume any desired position with relation to the bench clamp l0 and the top of the bench to which the vise has been applied, it is merely necessary to loosen the screw 23 freeing the spherical member l9 and permitting the same to be turned to any desired position within the spherical opening [4. The bench vise I is then free to be turned into any desired position and to again clamp the vise I5 in its adjusted position it is merely necessary to tighten the screw 23, causing the band 29 to again bear against the spherical member I9 and fixedly hold the same in position within the spherical opening l4.

According to the modification of the invention shown in Figs. 7-9 inclusive the bench vise comprises a bench clamp 30 which is substantially U-shaped in construction. The U-shaped bench clamp 30 is turned on its side forming a top arm 30 and a bottom arm 30. The top arm 30 is substantially longer than the bottom arm 30 and is adapted to rest on the top face of a bench to which the vise is applied. The bottom arm 3|] carries a screw 3| threadedly extended therethrough. A plate 32 is mounted on the top end of the screw 3| and is adapted to be clamped against the bottom face of the bench. The bottom end of the screw 3| carries a handle 33 by which the screw 3| is adapted to be conveniently rotated for causing the plate to be brought into and out of contact with the bottom face of the bench.

A body 34 is mounted upon the top arm 39 of the bench clamp 30. This body 34 is provided I A means is provided for holding the body 34 in various fixed positions along the length of the dove-tailed groove 33. This means comprises a screw 31 threadedly extended through the body 34, and which is adapted to abut the bottom face or the groove 36 as shown in Fig. 7 for fixedly holding the body 34 securely in position. The screw 31 is provided with a head 31 by which it is adapted to be conveniently rotated.

The body 34 is further provided with a zone of a spherical recess 38 which is open at its top and at its front side. A vise 33 is provided at its bottom with a substantially spherical member 40 which engages within the spherical recess 38 and which extends from the top thereof. The vise 39 comprises a fixed jaw 39* having a jaw element 39 and a movable jaw 39 having a jaw element 39 'cooperative with the jaw element 39. A screw 4| is provided for causing the movable jaw 39 to be moved towards and away from the fixed jaw 39. Several guide posts 42 are also provided for holding the movable jaw 39 in alignment with the fixed jaw 39.

' Means is also provided for holding the spherical member 40 in various fixed turned positions within the spherical recess 33 to similarly hold the vise 39. This means comprises a band 43 which is extended across the open side of the spherical recess 38 and which engages the spherical member 40. One end of this band 43 is securely held in position. To accomplish this a bolt 44 is extended through the end of the band 43 and is threadedly engaged into a complementary boss 45 formed upon the body 34. The other side of the band 43 is adapted to be releasably attached to the body 34. This is accomplished by means of a screw 46 which freely passes through the band 43 and which threadedly engages a complementary boss 41 formed upon the body 34. An enlarged head 46 is formed on the screw 46 and abuts the front face of the band 43. A handle 41 is mounted on the enlarged head 45 and is provided for permitting the screw to be conven iently turned to clamp the band 43 against the spherical member 40.

This form of the invention is also provided with a means for holding the vise 33 at various fixed elevational positions with relation to the spherical member 40. This means comprises several vertically extending rods 48 which extend from the top of the spherical member 40 and which pass through openings 49 formed in the vise 39. These rods 48 extend through the fixed jaw 39 of the vise and are arranged on either side of the screw 4| and the guide rods 42. The vise 39 is adapted to be moved upwards and downwards upon the rods 48 and a means is provided for fixing the vise in various adjusted positions thereon. This means comprises screws 50 threadedly extended in from the sides of the vise 39 and which are adapted to be clamped against the sides of the rods 38 as shown in Fig. 9 for fixedly holding the vise in various vertical fixed positions.
