It is within the province to improve generally and utility of devices of invention appertains.
With the above and other 01) which will appear as the ecially "bent "in of the disclosure to enhance the that type to which the ects in View description proceeds, the invention resides in the combination and arrangement of parts and 1n the details of construction hereinafter described and claimed, that changes in the the invention herein within the scope of it being understood precise embodiment of disclosed, maybe made what is claimed, with-' out departing from the spirit of the invention.
In the draw1ngs:
Figure 1 shows in elevation, a device constructed in accordance with the invention;
Figure 2 is a top plan;
Figure 3 is a section on Figure 1; p
- Figure 4 is a section on Figure 1.
The device forming this application preferably throughout, and includes form of a plate. A U-shap jects rearwardly thereof, one side of the br forced by an joined to said body 1.
' A clamping is mounted in the bracket 6, such as a vertical post,
available as a structural building where the conduit done, the operator can with such a post.

desired sort is mounted in the projection 7 andjin -the body, the securing element 14 extending across the seat 8 and through the end 9 "of the: diel'lO. The die 10 has a shoulder 15 which seats againstv the lowe'r edge 01' the projection 7, as shown in Figure 3 Owing to the-way in whichthe seat 8 and the end 9 of the die 10cooperate, to-
1 gether with. the further fact that the shoulder 15 is provided, practically all of the strain in the pipe-bending operation is taken off the'securing element 14, the securing element 14, serving, primarily, merely to pre-.
vent the die 10 from dropping downwardly out of the seat 8 in the projection 7.
Near to its lower end, the body 1 is supplied with afor'wardlyextended off-set 16, in
the upper edgeof which there is a'V-shaped seat 17 adapted to'receive the correspondingly shaped end 18 of a bracket 19 which lies against the body 1,the bracket 19 being provided in its upper end with a groove 20 which is complemental ;to the groove 12 of the die 10. A securing element 21 passes throughthe off-set 16 into the body 1 and extends through the end 18 ofthe bracket 19; but, as has been stated hereinbefore in connection with the securing element 14, there is little or no strain on the v securing element 21, the said securing ele"- ment merely retaining the. end 18 of the bracket 19. engaged in the The numeral 2 2 desi'gnates a metal con duit adapted to; be usedby electricians and it being necessary, very often, to

may be viewed readily, and the bending" can be carried on intelligently to an desired extent, or stopped at any point.
W hat is claimed is: In a pipe-bending device, a plate-like body provided ,at one end with a forwardly extended projection, and at its opposite end w th a forwardly extended offset, there being a seat in the lower surface of the PVFOJGCUOII,
and there being a seat in the upper surface of the offset, a die having a reduced end received in the seat of the projection, a bracket having a reduced end received in the seat of the offset, the bracket and the die being spaced for engagement With a pipe during the bending thereof, and securing elements 'engager'l with the reduced ends of the die and of the bracket, the aforesaid reduced ends ture.
