16 Claims. (Cl. 100-43) This invention relates to improvements in crushing machines. The main objects of this invention are:
First, to provide a crushing machine which is of relatively large capacity in proportion to its size.
Second, to provide a crushing machine which is well adapted for domestic use and for use in hotels, restaurants, saloons and the like and one which is highly efficient and easy to operate, being largely automatic in operation.
Third, to provide a crushing machine with charging means which prevent overloading and one in which the movable jaw is in operation before material is discharged into the jaws.
Fourth, to provide a crushing machine having these advantages in which the motor is automatically stopped when the crushed material receptacle is filled.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.
A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:
Fig. 1 is a front elevational view of a crushing machine embodying my invention.
Fig. 2 is a fragmentary side elevational view, a portion of the housing being broken away, the closure and the feed hopper relatively connected thereto being shown in open position by dotted lines.
Fig. 3 is a fragmentary view in transverse section on a line corresponding to line 3--3 of Fig. 2.
Fig. 4 is an enlarged fragmentary view partially in vertical section on a line corresponding to line 4-4 of Fig. 1.
Fig. 5 is an enlarged fragmentary view corresponding to that of Fig. 4 with the closure member shown in partially open switch disengaging position by dotted lines.
Fig. 6 is an enlarged fragmentary view of the movable jaw and its supporting and actuating means in section on a line corresponding to that of Fig. 2.
Fig. 7 is an enlarged vertical section corresponding generally to that of Fig. 4 and illustrating certain of the structural details of a debris actuated motor stop'switch.
Fig. 8 is a fragmentary view illustrating the movement of the movable jaw relative to the fixed jaw by full and dotted lines.
Fig. 9 is a conventionalized diagrammatic view of the motor control switches and their connections to the motor.
The embodiment of my invention illustrated comprises a housing, desirably of general rectangular section, and including front wall 1, rear wall 2, side walls 3 and top 4, the top having a charging opening therein provided with a closure 5 hinged at 6. These parts are desirably formed of sheet metal. The details of the connections for the parts are not illustrated as they form no partof this invention.
The front wall 1 is provided with an opening 7 at the lower end thereof adapted to receive the debris receiving receptacle 8 which is open at the top. The crushing jaws 9 and 10'are disposed in downwardly converging relation 2 and are provided with transversely disposed serrations or teeth 11. The jaw 9, desirably the front jaw, is fixedly mounted on the forward edges of the supporting members 12 and 13 which are fixedly mounted in opposed relation on the inner sides of the side walls 3 and in downwardly spaced relation relative to the top of the housing.
A chute member 14 extends from the front wall to the upper end of the front jaw 9. A charging hopper 15 is connected to the hinged end of the closure member 5 so that it is swung to receiving position when the closure member is open, as shown by dotted lines in Fig. 2, and to discharging position when the closure member is swung to the partially closed position, shown by dotted lines in Fig. 5. The purpose of this will be apparent as the description proceeds.
The movable or driven jaw 10 is supported and actuated to provide a crushing and material discharge movement, as generally illustrated in Fig. 8. The driven jaw 10 is powered from the electric motor 16 mounted on the vertically spaced brackets 17 and 18 on the support member 13. The motor shaft 19 is provided with a worm 20 with which the gear 21 coacts. The shaft 22 of the gear 21 is provided with an eccentric 23 which coacts with the bearing member 24 on the rear side of the jaw 10.
The upper end of the jaw 10 is movably supported by the downwardly and forwardly inclined links 25 which are mounted on the shaft 26 and pivotally connected at 27 to the rearwardly projecting supporting ears or lugs 28 on the rear side of the jaw 10 adjacent its upper end. This mounting and driving means gives a compound movement to this movable jaw 10, as is illustrated by the full and dotted lines in Fig. 8, and provides both a crushing and feed discharge action which is highly effective.
The main motor switch 29 is mounted on the inner side'of the front wall adjacent'the top thereof and is of the automatic closing type. The closure 5 is provided with a springable latch 30 which when the closure is in closed position, as shown by full lines in Fig. 5, engages the tappet 31 on the switch to open the switch. The latch in that position is in retaining engagement with the keeper 32. However this latch 30'supportedly engages the keeper as shown by dotted lines in Fig. 2, when the cover is in partially closed position.
With-this arrangement, as soon as the cover or closure is opened, the switch 29 automatically closes and starts the motor. When the cover is opened, as shown by dotted lines in Fig. 2, the hopper 15 is in charge receiving position. This insures that the motor and the movable jaw shall be in operation before the material is discharged between the jaws.
The shaft 19 of the motor is desirably provided with a balance wheel 33 of substantial Weight which minimizes the likelihood of the motor being stalled by the discharge of material between the jaws. To minimize the likelihood of clogging the jaws as the result of neglecting the emptying of the receptacle 8 a motor cutout switch 34 is provided, the receptacle being provided with a pivoted switch actuating member 35 disposed adjacent to but rearwardly of the discharge of the jaws, see Fig. 7. This switch 34 is conventionally shownprovided with a tappet or actuating member36 Theembodiment of my invention illustrated is espe cially designed for home or domestic use and in hotels, restaurants, saloons and the like and various other places. Certain of the parts are shown conventionally as the structural details form no part of this invention, however, the disclosure is such that it will enable those skilled in the art to embody or adapt the same as may be desired.
I have illustrated and-described my invention in a desirable and practical embodiment thereof. I have not attempted to illustrate various adaptations and modifications which I contemplate may be desirable for particular uses and capacities as it is believed this disclosure will enable those skilled in the art to embody or adapt the invention as may be desired.
