1 Claim.

This invention relates as indicated to a conveying-crusher and has more particular reference to a vibrating conveyor in combination with a crusher.

Vibrating conveyors are generally divided into two principal classes. First, there is the throwing type in which the material is thrown upward and forward and second, the closed path movement type in which the material is moved forward with a minimumof disturbance. This latter type depends upon friction between the material and the bed. The present invention is applicable to both types of vibrating conveyors, however, it is interested in the throw type primarily.

It is the principal object of the present invention to provide a vibrating conveyor which shall include crushing or breaking means, whereby oversize particles may be reduced to the proper size as they travel across the conveyor.

Other objects will appear as the description proceeds.

To the accomplishments of the foregoing and related ends, the invention then comprises the features hereinafter fully described and particularly pointed out in the claim, the following description and the annexed drawings setting forth in detail certain illustrative embodiments of the invention, these being indicativahowever, of but a few ofthe various ways in which the principle of the invention may be employed.

In said annexed drawings:

Fig. 1 is a side elevation view of an embodiment of the present invention;

Fig. 2 is a transverse sectional view taken through line 2-2 of Fig. 1;

Fig. 3 is a top plan view ofthe embodiment of Fig. 1;

Fig. 4 is a side elevation view of a slightly modi-. fled embodiment of the invention; and

Fig. 5 is a top plan view of the embodiment of Fig. 4.

Referring more specifically to the drawings, It! indicates side frame members of a main base. Vibrating conveyor l is movably mounted upon base H] as by a plurality of upwardly extending leaf springs ll. Any of the well known eccentric or vibrating means as for example motor [4 with eccentricdrive connected by arm [5 to bracket l6 may be associated with base [0 and conveyor I, the details of which form no part of the present invention. The conveyor structure may include side frame members l2 suitably secured together by any suitable transversely extending members l3. Plate 2 is suitably secured to conveyor l as 2 by welding, directly below crusher plate 3. Plates 2 and 3 are preferably made from hardened or special alloy steel, so that they will resist abrasive action encountered while crushing hard substances.

I have found the crusher of the present invention especially suited for crushing very hard and friable substances such as porcelain enamel and the like. Crusher plate 3 is positioned over plate 2 and held in place as by studs 8 and spring 4. Nuts 9'on studs 8 can be raised or lowered thus increasing or decreasing tension on springs 4. In this manner the amount of vertical motion of plate 3 can be controlled and thus the particle size of the material passing along the conveyor can be readily controlled at the discretion of the operator.

It is important to note here that any horizontal motion of plate 3 must be kept at a minimum. This is accomplished by arms 5 which are pivotally mounted on one end to bar 6, which extends through sides l2. Arm 5 is pivotally mounted on its other end to upstanding member I which is securely fastened, as by welding, to plate 3. In this manner plate 3 is able to operate in a vertical motion with arms 5 holding any horizontal motion to an absolute minimum.

Figs. 4 and 5 show another possible method of restricting horizontal motion. Arms 5a are in tandem arrangement and are pivotally mounted on bars 6a and upstanding members 1a.

It will be understood that the details of the vibrating means do not form part of the present invention. However, in response to the vibrating means the conveyor imparts a vertical motion to the crusher plate 3. A layer of material traveling from the feed end to the discharge end of the conveyor travels over plate 2. The vibration of the conveyor I causes a vertical motion of plate 3, the extent of such motion being controlled-by the tension of springs 4, whereby the material passing over plate 2 is crushed by the rapid vertical motion of plate 3.

My device has several particular-advantages over prior art practices of crushing. First my invention permits the simultaneous movement of the material to the discharge while it is being crushed to the desired size, secondly the particle size of the material can be readily controlled and thirdly the apparatus is relatively simple in construction and operation. One other outstanding advantage of my device consists in the restriction of any horizontal motion of crusher plate 3. This latter advantage is desirable principally for two reasons: first, since there is relatively no rubbing of plates 2 and 3 there is a minimum of wear to the plates and second, since this rubbing is held at a minimum the material being crushed picks up a minimum of iron from the plates as it is being crushed. This latter point is particularly valuable in the crushing of porcelain enamel. In the production of white and light colored porcelain enamel it is the utmost importance to hold the iron content of these materials at an absolute minimum. In the prior art practices of conveying and crushing materials of this type too much iron was picked up by the porcelain enamels. However, in my present invention this iron pick up is held to a minimum.

Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the feature stated in the following claim or the equivalent of such be employed.

I, therefore, particularly point out and distinctly claim as my invention:

In a device for simultaneously crushing and conveying including a vibrating trough conveyor, a first crusher plate mounted on said conveyor, a single second crusher plate of substantially the same width as said first plate and lying in a plane above the plane of said first plate, a support for said second plate mounted upon and upwardly extending from said conveyor, resilient members between said support and said second plate adapted to exert pressure on said second plate, a plurality of arms movably supporting said plate on said conveyor, one end of each of said arms being journaled to said second plate and the other end of each such arm member journaled to said conveyor at points such that said arms are substantially parallel, whereby said second plate oscillates substantially in a vertical plane in response to the vibrating movement of said conveyor.
