1. A crusher including:
- a pair of opposed crushing jaws, a pivotal mounting of each jaw for pivotal movement towards and away from the other jaw, means for driving the jaws to pivot towards each other simultaneously and away from each other simultaneously, the pivotal mounting of each jaw being adjacent one end of the jaw, the said one ends of the jaws being located opposite each other, the other ends of the jaws being located opposite each other, a drive shaft rotatably mounted on one of the jaws and having eccentric portions, a cross shaft rotatably mounted on the other of the jaws and having eccentric portions, a pair of connecting rods each pivoted at one end on a respective eccentric portion of the drive shaft and pivoted at the opposite end on a respective eccentric portion of the cross shaft, and means for adjusting the distance between the pivots at the ends of the connecting rods.

Abstract
A crusher, for example for rock or the like, has crushing jaws which are driven to swing towards and away from each other and are pivoted to a frame adjacent the ends of the jaws, so that most of the jaw movement is in a horizontal direction and is therefore a substantially balanced assembly.

5. A rock crushing apparatus comprising in combination
a frame, two pairs of crusher jaw pivot bearings mounted on the frame, a pair of jaws, a pair of horizontal shafts each extending from side-to-side of and outboard of a respective jaw and being pivotally secured in the respective pair of crusher jaw pivot bearings for suspending the respective jaw in opposed relationship as to the other jaw, a reciprocating mechanism for the simultaneous swinging of the jaws with equal force toward each other and away from each other about the respective crusher jaw pivot bearings and including: -
a. a horizontally-disposed driving shaft extending from side-to-side of and outboard of one of the jaws, b. a horizontally-disposed cross shaft extending from side-to-side of and outboard of the other of the jaws, c. a pair of bearings mounted on the said one of the jaws for the journalling of the driving shaft therein, d. a pair of bearings mounted on the said other of the jaws for the journalling of the cross shaft therein, e. a pair of driving shaft eccentrics on opposite ends of the driving shaft, f. a pair of cross shaft eccentrics on opposite ends of the cross shaft, g. a pair of connecting rods each being mounted at one of its ends on a respective one of the driving shaft eccentrics and at the opposite of its ends on a respective one of the cross shaft eccentrics, and h. drive means for driving the driving shaft, all adapted and arranged whereby rotation of the driving shaft and of the driving shaft eccentrics effects simultaneous swinging movements of the jaws toward and away from each other. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
