IN V EN TOR..
Patented Oct. 22, 1946 MATERIAL CLEARING ATTACHMENT FOR JAW CRUSHJNG MACHINES Albert Fillmore Hyde, New York, N. Y.
Application April 26, 1945, Serial No. 590,490
1 Claim.
This invention relates to a clearing attachment for crushing machines such as used for crushing stone.
It is a fact well known to those skilled in the art that crushing apparatus frequently becomes choked by particles which become hung between the relatively movable jaws with the result that the machine cannot again be operated until this obstruction has been removed. The removal of obstructions frequently becomes a tedious and laborious job causing lengthy delays and consequent reduction in production.
An object of the present invention is to equip a crushing machine with an attachment by which any obstruction which may become lodged be tween the jaws of the machine, can be forced out of position quickly so that the stoppage in production will be minimized.
A further object is to provide an attachment of this character which can be applied readily to crushing machines already in use.
With the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certain novel details of construction 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 improvement combined therewith.
Figure 2 is a section on line 22 of Figure 1.
Referring to the figures by characters of reference, I designates the body of the crushing machine which, in the structure illustrated, is provided with a fixed jaw 2 and a movable jaw 3. This latter jaw is shown mounted on a pivot 4 at its upper end while the lower portion thereof is actuated by a pitman 5 receivin motion from a rotatable eccentric 6 which can be driven by any means desired. It is to be understood that the structure heretofore described is common in crushing apparatus and that the present improvement can be used in connection With other types of crushers wherein relatively movable jaws are used.
For the purpose of removing articles from between the jaws if it is not possible to crush them, there is provided an attachment in the form of a flexible length of material such as a chain 1 or the like, one end of which is anchored to one side of the body I as at 8 while the other end is in engagement with a jack 9. With these parts properly placed, the chain 1 can be supported freely between the jaws so that material to be crushed can be directed into the space between the jaws and above and around this chain.
If some object incapable of being crushed between the jaws becomes deposited in the throat IU of the machine, all that is required is to actuate the jack 9 so as to draw the lifting device 9 upwardly relative to the jaws. Thus the object supported between the jaws and above the bottom portion of the lifting device, will be pulled forcibly 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 without 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 a throat for the reception of material to be crushed therebetween, of a flexible device anchored at one end above and at one side of the throat, said device having a loop depending between the jaws at a plane parallel with the axis of movement of the movable jaw, and a lifting device connected to the other end of the device constituting means for raisin and lowerin the loop relative to the jaws between which it is suspended, said loop being normally extended from one side to the other of the throat.
