PIPE-BENDING ionvron' I Application filed November '22, 1926. Serial NO.149,809.
This invention relates to pipe bending devices, the principal object of which is provide a more practical, and simple device of this character than heretofore known.
Other objects and advantages of the nvention will appear in the further descrlption thereof.
Referring now to the accompanying drawing, forming part of this appl1cat1on, and wherein like reference characters indicate like parts:
Figure 1 is a .perspective view of the improved shaping device; and
Figure 2 is a perspective view of the end of the jaw adjusting bolts.
1 represents a channel shaped metal frame or body portion to which the bending mechanism is attached, and this form of body portion is particularly designed for engagement with a rectangularly shaped supporting objectsuch as a post, horizontal timber or the like, for securely supporting said body portion. For securing the body por tion to the post or other member I have provided the adjustable screw threaded bolts 2 through one side of the channel wall. Upon the back thereof is formed the integral arcuately shaped concavo-convex jaw or bending member 3, though the same may be permanently fixed to the body portion in some other manner if desired. The back of this fixed jaw is provided with a round socket 4 which is internally screw-threaded and in direct alignment with the hole 5 in the laterally projecting lug 6 on the corner of the body portion spaced some little distance from the jaw 3. This arrangement is pro vided for the insertion of a handle indiat 7, which may be thrust through the hole 5 and engaged within the socket 4, the'end of said handle preferably being screw-threaded for such engagement, so that in the event of not being able to conveniently mount the device upon a post, timber, or the like, apiece of pipe, for example, or rod screw threaded upon its extreme end may be inserted within these aligned holes 4 and 5 and the device thus permanently held in lieu of other means of support.
Facing the jaw 3 is a like supported upon the back of the body portion by means of two externally screwthreaded bolts 9, spaced one above the other and supported within the lugs 10 formed integral with the back of the body. These jaw 8 adj ustably bolts are rotatably mounted within the hub like protrusions 11 on the back of the jaw 8, each bolt having an annular channel 12 spaced a short distance from the extreme end thereof as clearly shown in Figure 2, and the hubs 11 being provided with transverse holes for registration with the channels 12, permitting of a cotter pin 13 being placed therethrough when the bolts are in position within their respective hubs, thus preventing accidental disengagement and yet allowing the bolts to freely rotate Without stress upon the jaw. While the opposite ends of the bolts may be provided with heads if desired I have shown them simply as squared, as at 14, for convenient application of a Wrench.
The operation of the device is as follows:
The body portion 1 may be clamped upon an upright rectangularly shaped post, if such is convenient, or upon an iron rod such as illustrated at 7 firmly held within a vise for example, when the round iron or pipe as the case may be which is to be'bent is inserted vertically intermediate of the jaws 3 and 8, when the bolts 9 may be screwed up until the jaws impinge the material to be bent. The bending is accomplished by applying stress towards the support 7 for example, either or both ends of the material be ing bent in either direction as desired, only, however, to the curvature represented b that of the jaws, and the adjustability of which may be slackened for feeding thepipe or rod through to any extentdesired, when the same may be again tightened for such bending operation. As the bolts 9 are independently adjustable, it is obvious that either end of the adjustable jaw may be set up slightly in advance of the other for the more delicate curvature of the object being bent.
From the foregoing it is evident that I have devised an exceedingly simple and practical device wherein a piece of iron or pipe may be conveniently bent and the relative position of the bending jaws adjusted to accommodate different sized pipes, 01' assist in the bending process.
Having thus described my invention, what I claim and desire to secure by Letters Patent, is:
1. A bending device of the class described comprising a channel shaped body portion, means for rigidly holding same, an arcuately shaped concave-convex jaw fixed to one face H Q v r 1,664,138
thereof, a second jaw spaced from the first opposite similarly shaped jaw normally mentioned jaw and of similar shape, and spaced therefrom, and a pair of spaced ad- 1 spaced adjusting means for independently justable supporting bolts for said latter jaw moving opposite ends of the last mentioned for the purpose described. 5 jaw. In testimony whereof I aflix my signa- 2. A bending device of the classdescribed tnre. comprising a body portion, a fixed arcuately shaped jaw upon one face thereof andv an JOHN SUNDGREN,
