7 I Application December 15, 1942, Serial No. 469,893

1 Claim. (Cl. 153-10) My invention. relates-to improvements in crushing machines, the principal object in view being to provide an easily operative mechanism, for domestic or other use, in quickly crushing tin, or other metal, cans fiat for compact storage in shipping to metal reclaiming plants and the like, and which is simple in construction involves few parts, is inexpensive to manufacture and install, and will not jam.

Other and subordinate objects are also comprehended by my invention, all of which, together with the precise nature of my improvements, will be readily understood when the succeeding description and claim are read with reference to the drawings accompanying and forming part of this specification.

In said drawings:

Figure 1 is a View in side elevation of my improved crushing machine in its preferred embodiment,

Figure 2 is a view in top plan,

Figure 3 is a view in vertical longitudinal section taken on the line 3-3 of Figure 2,

Figure 4 is a detail view in transverse section taken on the line 4-4 of Figure 2,

Figure 5 is a similar view taken on the line 55 of Figure 2, and

Figure 6 is a View in transverse section taken on the line 66 of Figure 2.

Referring to the drawings by numerals, in the illustrated embodiment thereof my improved crushing machine comprises an elongated, generally rectangular, frame including corner legs I, horizontal, upper side and end cross bars 2, 3 connecting the legs I at the top of the frame, horizontal, lower side bars 4 connecting said legsv l adjacent the bottom of the frame and horizontal side and end cross bars 5, 6 interas at M, to one leg I and has its other end slidably fitted in a rabbet provided in the other side edge of the block I l, whereby said plate is swingable outwardly and inwardly of the frame and relative to the plate 1 for a purpose presently seen and limited as to inwardswinging by a shoulder lfi'forming part of the rabbet l5. v,A pair of opposed crusher discs H, w re mounted on the plates 1;, 8 to rotate between said plates on suitable axis members l9 extending, at right angles from the plates 1, 8. The discs I1, I 8, as will be seen, converge in correspondence with the plates 1, 8 into close proximity at one end of the frame and are provided with conical mediate the bars 2, 3 and said bars 4, and fur- One of the plates, for instance, I, is fixed at one end, as at 9, to one leg, the other end of said plate being set into a rabbeted side edge 10 of a supporting block II and bolted, as at l2, to said block. The block II is welded, as at l3, to one of the end cross bars 6 in the center thereof and in upright position. The other plate 8 is hinged,

opposed working faces 20 which, by virtue of the convergence of the disc, present peripheral portions upon one side of the axes of the disc spaced close together to form a bight in the horizontal center of the discs for crushing cans fed between said discs.

A gravity feed, rectangular hopper 2| is suitably mounted by cross bars 22 at the top of the frame to depend between said working faces 20 of the discs l1, l8. Preferably the hopper 2| is provided with end walls 23 inclining downwardly between said discs I1, 18 in the direction of rotation of the latter, which is clockwise, as indicated by the arrows in Figures 1 and 3. The edges of the end walls 23 converge downwardly to fit in between the working faces 28 above the described bight of said discs.

Backing rollers are provided for the discs l1, 18 to prevent undue strain on the axis members l9 thereof. Preferably, for this purpose, a pair of upright bars 25 are suitably fixed to the outer sides of the plates 1, 8 opposite the bight of the working faces 28, each bar having a suitably mounted thereon a pair of upper and lower rollers 24 adapted to bear against the outer face of the adjacent disc adjacent the bight of the discs. On the other side of the axes of the discs [1, l8 a single roller 24 suitably mounted on the appropriate plate 1 or 8, as the case may be, bears against the outer face of the disc.

Cushion springs 25 urge the plate 8 inwardly and the disc l8 toward the disc ll. Preferably, a pair of such springs are arranged between the ends of the bar 25 carried by the plate 8, and the ends of a similar bar 21 opposed to the bar 25 and fast on a support 28 suitably fixed in the frame. The bar 21 and opposed bar 25 are provided with spring seating sockets 29 of the usual type.

Means for driving the discs l8, l9 are provided as follows: An electric motor 30 is mounted on a bed plate 3| supported by the side bars 4 at the side of the axes of the discs opposite to the bight of said discs. A cross shaft 32 is suitably mounted at its ends in the plates I, 8 to extend across the edge of the discs I1, l8 at their most widely spaced point. The mounting for one of the shaft 32 comprises a bearing 33 in which the shaft 32 is slidable and which is swiveled on the plate 8, as represented at 34, to compensate for swinging of'said plate. A pair of beveled gears 35 fast on the shaft 32 mesh with similar peripheral gear teeth 36 formed on the discs l1, 18. The armature shaft 31 of the motor 30 is operatively connected to the shaft 32 'by a sprocket and chain drive 38. I

The operation of the invention will be readily understood. The cans to be crushed are placed in the hopper 2| to feed into the bight of the discs I1, H] where, under rotation of the latter by the described drive means, said cans are crushedand flattened out to'be discharged downwardly from between said discs. The disc 18 is fioatingly mounted by means of the hinged supporting plate 8 to yield outwardly in opposition to the springs so that said discs cannot become jammed by the passage of cans through the bight formed thereby. Any suitable controls may be provided for the motor 30.' It is contemplated that the teeth 36' on the disc 18 and those of the bevel gear 35 meshing with said teeth be formed in the proper length to constantly mesh in sliding engagement during lateral movement of the plate 8 and disc I8.

The foregoing will, it is believed, sufiice to impart a clear understanding of my invention without further explanation.

Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended'claim.

What I claim is:

In a machine for crushing cans and the like, a frame, a pair of crusher discs having conical working faces and rotatably mounted in said frame in side-by-side converging relation to disof said disc.

HAROLD G. EDWARDS.
