Adjustable Sidewardly Located Bar Puller
|
James R. Buck |
Cape Coral, Lee County, FL |
Abstract:
A bar puller having a body which mounts a pair of rockers which project forwardly to effectively straddle a bar. The rockers mount rollers on the free ends thereof, the latter being provided with elastomeric surfaces to effect gripping of the bar. An adjusting mechanism coacts between the rearward free ends of the rockers to permit the minimum spacing between the rollers to be selectively adjusted to accommodate a selected bar size, and to permit the initial gripping pressure of the rollers on the bar to be selectively adjusted.
Claims:
1. A bar puller for use with a machine tool for engaging and pulling on a bar for advancing the latter axially of the machine tool, said bar puller comprising:
a support body adapted for securement to the machine tool; first and second levers pivotally supported on said body for swinging movement about subsstantally parallel axes, said levers projecting outwardly from said body substantially beyond said axes so that the levers project generally in the same direction, said levers projecting outwardly and terminating in free ends; a roller rotatably supported on each of said levers adjacent the free ends thereof, each said roller being supported for rotation about an axis which is substantially parallel to the pivot axis; stop means mounted on said body for cooperating with said first and second levers for limiting the inward swinging of the levers and the rollers thereon toward one another for defining a minimal spacing between said rollers which is less than the diameter of said bar;
manually actuable adjusting means for adjusting the position of said stoop means relative to said body to selectively adjust the magnitude of said minimal spacing between said rollers;
said stop means incuding a pair of stop members movably supported on said body, spring means coacting between said stop members and normally urging them outwardly in opposite direction, and a pair of stops fixed to said body, said spring means normally maintaining said stop members in engagement with said stops; and said adjusting means including threaded adjusting members co-acting with said stop members and being threadably engaged with said levers so that rotation of said threaded adjusting members causes the position of said stop members to be adjusted relatve to said levers so as to vary said minimal spacing between said rollers.
2. A bar puller according to claim 1, wherein each said adjusting member is threadably engaged with a respective said lever and is axially coupled with a said stop member, said body having a bore therein extending substantially perpendicularly with respect to said axes, said stop members being movably disposed within said bore adjacent opposite ends thereeof with said spring means being disposed between said stop members, said adjusting members projecting outwardly in opposite directions from said stop members for threaded engagement with said levers.
3. A bar puller according to claim 1, wherein said adjusting means includes a pair of said threaded adjusting members which are rotatably coupled together and rotatably supported on said body, said pair of threaded adjusting members being oppositely threaded and each being threadably engaged wit a respective said lever.
4. A bar puller according to claim 1, wherein each said roller has a thread of an elastromeric material extending therearound.
5. A bar puller for use with a machine tool for engaging and pulling on a bar for advancing the latater axially of the machine tool, said bar puller comprising:
a support body adapted for securement to the machine tool;
first and second levers pivotally supported on said body for swinging movement about substantially parallel axes, said levers projecting outwardly from said body substantially beyond said axes so that the levers project generally in the same direction, said levers projecting outwardly and terminating in free ends;
a roller rotatably supported on each of said levers adjacent the free end therreof, each said roller being supported for rotation about an axis which is substantially parallel to the pivot axis;
manually actuable adjusting means cooperating with said first and second levers for adjusting the magnitude of a minimal spacing between said rollers;
said adjusting means including elongated rod means rotatably supported on said body and extending in generally perpendicular relationship relative to said axes;
said adjusting means also including first and second threaded coupling means connected between said rod means and said first and second levers respectively, said first and second threaded coupling means being threadably engaged with said rod means and having threads which are of opposite hand so that rotation of said rod means causes the levers to be pivotally displaced in opposite directions about their respective axes; and stop means co-opoerating between said body and said rod means for permitting limited axial displacement of said rod means relative to said body.
6. A bar puller according to claim 5, wherein each said roller has a tread of an elastomeric material extending there around.
7. A bar puller according to claim 6, wherein each said threaded coupling means includes a nut member which is threadably engaged wit said rod means and is carried by the respective said lever.
8. A bar puller according to claim 7, wherein each said nut is pivotally supported on its respective said lever for pivoting about an axis which is generally parallel with but spaced transversely from the axis which pivotally supports the lever.
9. A bar puller according to claim 5, wherein said adjusting means includes spring means for continually urging the levers toward a rest position wherein the spacing between the rollers is slightly less than the diameter of a bar which is to be engaged by the rollers.
