  It is therefore the principal object of this invention to provide a manually operated steel handling device. which will be of such structure. so as to enable a steel worker to safely roll over structural steel shapes, such as eye beams and channels.  
  Another object of this invention is to provide a device of the type described, which will eliminate the use of the unsafe pry bars of the prior art which when used. sometimes trapped the operator. or, if the operator let go protect himself. the pry bar would become a dangerous projectile.  
  A further object of this invention is to provide a device of the type described which will include a jaw having a slot portion for engaging a longitudinal flange of structural steel, the jaw also including spaced apart pin means at one side for effectively engaging the web portion of a structural steel member so as to roll the structural steel member over by handle grip means attached to the jaw.  
  A still further object of this invention is to provide a device of the type described, which will have a handle member for providing the necessary mechanical advantage. the handle member being secured by bolt fastener means. the head of which abuts with a concave washer which applies the necessary friction in the flexing joint of the device.  
  Other objects of the invention are to provide a structural steel handling device which is simple in design, inexpensive to manufacture, rugged in construction. easy to use and efficient in operation.  
  These and other objects will be readily evident upon a study of the following specification and the accompanying drawing, wherein:  
  FIG. 1 is a vertical view of the present invention shown in elevation;  
  FIG. 2 is a side view of the invention shown in use, the pins of the device being showing engaging the web of an eye-beam so as to enable the operator to roll the beam over;  
  FIG. 3 is a fragmentary side view of the device showing the slot engaging a flange of an eye beam;  
 FIG. 4 is similar to FIG. 3;  
 FIG. 5 is an enlarged plan view of the connecting bolt fastener, showing the friction spring of the device.  
  According to this invention, a structural steel handling device 10 is shown to consist of. a jaw 11 member having a slot opening 12 providing for receiving the longitudinal flange 13 of beam 14. A pair of spaced apart and projecting pins 15 adjacent to the slot opening 12, provides for receiving between them, the web 16 of beams 14 at one end of the beam 14 so as to roll beam 14 over. Jaw 11 includes a lip portion 17 which is engageable with edge 18 of the elongated handle 19 which provides for the necessary leverage to apply a mechanical advantage to enable rolling beam 14. Handle 19 is secured to jaw 11. by means ofa threaded bolt fastener 20 which threadably engages an internally threaded opening 20a of jaw 11. An arcuately configurated spring washer 21 is carried upon bolt fastener 20 so as to provide the necessary friction between jaw 11 and handle 19.  
  In use, as seen in FIG. 2 of the drawing, the pins 15, are one each engaged with a side of web 16 so as to enable the user to apply torque by means of the handle 19 so as to roll beam 14 over, the device 10 being applied to the end of the beam 14 for such an operation.  
  As will be seen in FIGS. 3 and 4 of the drawing. a slotted opening 12 of jaw 11 receives the longitudinal flange l3 beam 14 so as to apply torque by means of handle 19, to roll beam 14.  
 What I now claim is:  
  1. A structural steel handling device. comprising in combination, an elongated plate forming a jaw memher. said jaw member having a slot in one end thereof extending from an end edge for receiving a flange of a structural beam, a pair of spaced apart pins located along one logitudinal side edge of said jaw, said pins projected transversely through said plate and extending a substantial distance from both sides of said jaw plate, an elongated handle attached to said jaw member wherein said elongated handle is pivotally attached at one end to a longitudinally intermediate portion of said jaw member by means of a transverse bolt, one end of said jaw member having a lip turned at right angle to a flat plane of a remainder of said jaw member. said lip being aligned with an edge of said handle for abutment therewith, said handle and said jaw member are in a common relatively straight line when said handle is in abutting relationship to said lip.
