Quick detachable bucket

Claim 2

A quick detachable bucket for a front end loader having lifting arms and a movable plate member movably mounted on the lifting arms, a loading frame having its lower outer corners pivotally mounted to the outer ends of the lifting arms and its upper portions pivotally mounted to the plate member for movement of the loading frame by the loader, said bucket having an open mouth at its forward edge and a rear wall, central upper spike means and eyelet means with said spike means receivable in said eyelet means to interengage one another and with one of said means mounted to the central upper edge of said rear wall and the other of said means mounted to the central upper front edge of said frame, said bucket and frame having lower outer hook means and lower outer spring biased rod means comprising two rods pivoted about a horizontal axis, with one of said means mounted to the bucket and the other of said means mounted to the frame and coacting with one another to automatically latch the bucket to the frame upon impact of the lower portion of the bucket to the frame, whereby the spike may be inserted into the eyelet and the frame may lift the bucket upward and rearward to cause the bucket to swing down and impact against the frame to latch the bucket to the bucket to the frame at its lower outer corners by the latch and rod means, camming means acting to cam the rods relative to the frame in opposing directions along a path laterally between the lower outer corners of the bucket and frame to facilitate the latching of the lower outer corners of the bucket to the frame.

Claim 3

A quick detachable bucket for a front end loader having lifting arms and a movable plate member movably mounted on the lifting arms, a loading frame having its lower outer corners pivotally mounted to the outer ends of the lifting arms and its upper portions pivotally mounted to the plate member for movement of the loading frame by the loader, said bucket having an open mouth at its forward edge and a rear wall, central upper spike means and eyelet means with said spike means receivable in said eyelet means to interengage one another and with one of said means mounted to the central upper edge of said rear wall and the other of said means mounted to the central upper front edge of said frame, said bucket and frame having lower outer hook means and lower outer spring biased rod means comprising two rods pivoted about a horizontal axis, with one of said means mounted to the bucket and the other of said means mounted to the frame and coacting with one another to automatically latch the bucket to the frame upon impact of the lower portion of the bucket to the frame, whereby the spike may be inserted into the eyelet and the frame may lift the bucket upward and rearward to cause the bucket to swing down and impact against the frame to latch the bucket to the frame at its lower outer corners by the latch and rod means, camming means acting to cam the rods relative to the frame in opposing directions along a path laterally between the lower outer corners of the bucket and frame to facilitate the latching of the lower outer corners of the bucket to the frame, said lower outer latch rods having linkage means connecting said latch rods together so as to cause said latch rods to operate simultaneously, a cable connected to a portion of said latch rod to actuate said latch rod to unlatch simultaneously.
