In one embodiment, thefirst clamp bar 40 a contains twobores second clamp bar 40 b also contains twobores bolts 41 or other attaching means. Thebolts 41 or other attaching means may be used to secure thepin 24 in theinsertion ramp 34 via theremovable clamp 40.Bolts 42 or similar devices well known to those of ordinary skill in the art may be used to secure thepins 41 once they are disposed through theinsertion ramp 34 and theremovable clamp 40. - The
connection device 10 described above is advantageous in that it eliminates the time consuming process of aligning (and maintaining the alignment) of the holes in heavy mobile conveyors/mobile conveyor sections and eliminates the need for press fitting a pin through the aligned holes in order to attach mobile conveyors. Instead, theconnection device 10 disclosed herein allows for quick assembly and de-assembly without the use of complex equipment, without endangering employees and without welding the mobile conveyors/mobile conveyor sections together. - It is to be understood that the form of this invention as shown is merely a preferred embodiment. Various changes may be made in the function and arrangement of parts; equivalent means may be substituted for those illustrated and described; and certain features may be used independently from others without departing from the spirit and scope of the invention as defined in the following claims.
