BEND ING BAR WITH ADJUSTABLE WORK ENGAGING STUDS Filed Aug. 9, 1947 ya mmwpw fitter/lays Patented Oct. 3, 1950 BENDING BAR WITH ADJUSTABLE WORK ENGAGING STUDS Charles M. Le Masters, Long Beach, Calif. Application August 9, 1947, Serial No. 767,724
2 Claims This invention relates to improvements in adjustable bending bars and may be considered as an improvement over the construction disclosed in my copending and now abandoned application Serial No. 566,373, filed December 2, 1944.
An object of the present invention is to provide an improved bending bar consisting of a shank to which a handle may be either integrally or detachably connected and having an upstanding polygonal stud to which a pair of sockets may be applied in superposed relationship in any of a plurality of positions, the sockets havin outwardly extending ends thereon on which there are upstanding posts. A feature of the improvement resides in the formation of the sockets so that the end of one socket or that socket which is positioned lowermost on the stud extends upwardly and the end of the other socket extends downwardly so that the .bases of the studs are in substantially the same horizontal plane in which the longitudinal axis of the shank and its handle are disposed. I find that when a bending bar is thus constructed wherein the shank has its longitudinal axis in a plane extending through the bases of the posts, when the bending bar is applied to an article to be bent or straightened, the twisting tendencies of the bending bar are eliminated.
Another object of the invention is to provide a bending bar having the above mentioned characteristics wherein one of the posts is knurled or otherwise roughened to prevent its slipping with relation to the article that is to be bent and wherein the other post has a rotatable sleeve thereon which preferably presents a smooth external surface so that in-the course of bending an article such as a length of pipe, the sleeve may roll or turn on its post and roll relatively to the article that is being bent in the course of bending.
With the foregoing and other objects in view, which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:
Figure l is a top plan view of the bending bar embodying the present invention;
Fig. 2 is a view inside elevation of the same;
Fig. 3 is an exploded view of the sockets and posts which are applicable to the stud on the shank; and
Fig. 4 is a view in side elevation parts being broken away and shown in vertical section of a socket carryin a rotatable sleeve on its post.
l and are welded in position so Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the improved bending bar consists of a shank generally indicated at H] on one end of which there is formed a head H. A polygonal stud I2 extends upwardly from the head II and is integral therewith. This studis illustrated as being hexagonal in plane although other polygonal shapes may be utilized if desired. A pair of sockets is provided, these sockets being indicated at E3 and M respectively. The sockets have polygonally shaped interiors and if the stud i2 is hexagonal in plane it is preferable to have each socket l2 sided on its interior so that when a socket is applied to the stud it may assume any one of 12 different positions with relation to the stud. In each position each socket is non-rotatable with respect to its stud.
Each socket has an end extending radially outward therefrom, such ends being indicated at l5 and I6 respectively. The socket I3 which is disposed lowermost on the stud 52 has its end I 6 bent or extending upwardly and in a similar manper the socket It has its end [5 bent or extend.-
ing downwardly so that the top surfaces of the ends at the bases of the posts thereon will be substantially in the same horizontal plane when the sockets are assembled in superposed relationship on the stud. It is possible to make the sockets i3 and i4 exact duplicates of each other in the course of manufacture, leaving one socket, such as l3, disposed upright and turning the other socket l4 upside down to properly position its end. Posts El and I8, respectively, are inserted through drilledholes in the ends of the socket as to be permanently associated therewith. These posts have their upper ends terminating in the same horizontal plane when the sockets are assembled on the shank and are preferably vertically knurled or otherwise roughened to prevent slippage. The bases of the posts are disposed in the same horizontal plane and the shank H1 is so bent with relation to the head I i that the longitudinal axis of the straight or handle portion l9 thereof is disposed in the same plane as the bases of the posts ii and 13. A tubular handle 28 may be slipped onto the shank and retained thereon by means of a bolt or rivet 21 carrying a spring actuated ball 22 that serves as a detent to retain the bolt in applied position. However, on forcing the bolt 2! out of its hole that extends through the handle and the shank, the handle may be detached from the shank to facilitate packaging or storing.
It will be appreciated from the above described construction that the two sockets l3 and I4 and their posts I7 and is may be caused to assume any one of twelve different possible positions with relation to each other and with relation to the longitudinal axis of the portion 19 of the shank In so that the device may be adjusted to any reasonable position with relation to the shank to facilitate bending of an article positioned between the two posts I! and I8. I find that when the tool is constructed as above described with the axis of the portion 19 in the same plane as the bases of the posts I1 and I8, when a bending force is applied to the handle 20, twisting tendencies are eliminated. If the handle 20 is disposed in the same horizontal plane as the head H, as in my copending application, there are certain situations wherein reactionary forces set up in the course of bending tend to twist the tool. This is largely if not entirely eliminated if the shank is arranged as illustrated.
Near the top of the stud l2 there is preferably a horizontal bore 23 within which balls 24 are confined such as by peening the metal at the ends of the bore. The compression spring 25 is disposed in the bore and urges the balls outwardly into engagement with the interior of the upper socket so as to frictionally retain the upper socket on the stud once that it has been applied thereto.
In the construction shown in Fig. 1, the socket l3a, which is a counterpart of the socket 13, has a post lla secured to its outer end. About this post there is disposed a sleeve 28 which is retained thereon by means of a cap screw 27 and washer 28. This sleeve preferably presents a smooth exterior surface. This form of socket and post may be advantageously used in bending pipe and the like wherein the post 18 by reason of its roughened surface will tend to grip and remain stationary with relation to the pipe and in the course of bending the pipe, the sleeve 26 will merely roll on its post l'la during the course 0:" bending.
From the above described construction it will be appreciated that an improved adjustable bending bar is provided which is highly advantageous in its construction and in the manner in which it may be used.
Various changes may be made in the details of construction without departing from the spirit and scope of the invention as defined by the appended claims.
I claim:
1. A bending bar comprising a shank having an upstanding polygonal stud, a pair of sockets receivable in superposed relationship on said stud in either of a plurality of positions, said sockets being duplicates and having outwardly extending offset ends, said sockets being mounted on said stud so that the offset end of one socket extends upwardly and the offset end of the other socket extends downwardly, and posts rigidly secured to the ends of the sockets and extending upwardly therefrom, the shank having a handle thereon, the longitudinal axis of which is disposed in a plane extending through the bases of the sockets.
2. A bending bar comprising a shank having an upstanding polygonal stud, a pair of sockets receivable in superposed relationship on said stud in either of a plurality of positions, said sockets being'duplicates and having outwardly extending offset ends, said sockets being mounted on said stud so that the offset end of one socket extends upwardly and the offset end of the other socket extends downwardly, and posts rigidly secured to the ends of the sockets and extending upwardly therefrom, the shank having a handle thereon, the longitudinal axis of which is disposed in a plane extending through the bases of the sockets, one of the posts having a sleeve rotatable there on and presenting a smooth exterior surface.
