Y. 1 Application April 26, 1945, Serial No. 590,490 1 Claim. (Cl. 241-265) This invention relates to a clearing attach ment for crushing machines such as used for crushing stone. It is a fact well known to those skilled in the 2 structure heretofore described is common in crushing apparatus and that the present improve ment can be used in connection With other types of crushers wherein relatively movable jaws are art that crushing apparatus frequently becomes 5 used. choked by particles which become hung between For the purpose of removing articles from be the relatively movable jaws with the result that tween the jaws if it is not possible to crush them, the machine cannot again be operated until this there is provided an attachment in the form of obstruction has been removed. The removal of a flexible length of material such as a chain 1 or obstructions frequently becomes a tedious and 10 the like, one end of which is anchored to one side laborious job causing lengthy delays and conse of the body I as at 8 while the other end is in quent reduction in production. engagement with a jack 9. With these parts An object of the present invention is to equip properly placed, the chain 1 can be supported a crushing machine with an attachment by which freely between the jaws so that material to be any obstruction which may become lodged bee 15 crushed can be directed into the space between tween the jaws of the machine, can be forced out the jaws and above and around this chain. of position quickly so that the stoppage in produc If some object incapable of being crushed be tion will be minimized. tween the jaws becomes deposited in the throat A further object is to provide an attachment of IU of the machine, all that is required is to ac this character which can be applied readily to 20 tuate the jack 9 so as to draw the lifting device crushing machines already in use. 9 upwardly relative to the jaws. Thus the object With the foregoing and other objects in View supported between the jaws and above the bottom which will appear as the description proceeds, the portion of the lifting device, will be pulled forcibly invention consists of certain novel details of con struction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed. In the accompanying drawing, the preferred form of the invention has been shown. In said drawing: Figure 1 is a vertical section through a portion of a crushing, machine having the present im provement combined therewith. Figure 2 is a section on line 2—2 of Figure 1. in an upward direction so as to be easily removed. Consequently, time heretofore wasted in removing obstructions by the use of various kinds of tools, etc., is saved and production is maintained with out undesirable loss of time. Under normal conditions, the lifting device 9 is of course in its lowermost position. What is claimed is: ' The combination with opposed crushing jaws, one of said jaws being movable toward and from the other jaw, said jaws cooperating to provide 35 a throat for the reception of material to be crushed therebetween, of a ?exible device an chored at one end above and at one side of the Referring to the ?gures by characters of ref throat, said device having a loop depending be erence, I designates the body of the crushing ma tween the jaws at a plane parallel with the axis chine which, in the structure illustrated, is pro 40 of movement of the movable jaw, and a lifting vided with a ?xed jaw 2 and a movable jaw 3. device connected to the other end of the device This latter jaw is shown mounted on a pivot 4 at constituting means for raising and lowering the its upper end while the lower portion thereof is loop relative to the jaws between which it is actuated by a pitman 5 receiving motion from a suspended, said loop being normally extended rotatable eccentric 6 which can be driven by any 45 from one side to the other of the throat. means desired.
