The buckets A, which are two in number,

are preferably made with only a bottom and r two'opposite sides, as shown, the back being left, open. It is, however, evident that the particular shape of buckets which is best adapted for handling the material working in may be employed.

pivoted upon a main pivot-bar or shaft 0. The levers B are-preferably pivoted to the sides of the buckets near their forward endsthat' is, the ends which meet when they are closed.

The position of the buckets is controlled by a system of auxiliary levers and links connecting the rear end of the buckets with the main levers, and consisting of triangular levers E and links D. The triangular levers E are pivoted to the main levers by the rods G,

which also'serve to connect the levers upon I opposite sides of the buckets and to thus stifien the construction. versof opposite halves of the b ucket' are pivot 1 ed'to-each other by a similar rod H, and the .;links D'are pivoted by one end to the other corner of the triangular levers and by their other ends to the buckets.

. from the center line of the bucket when itis closed, as shown in "Fig. 2, the main levers being bent outward in shape, like a bent elbow or knee, to accommodate it. The exact location of the various pivots and the proportions of the parts may be varied within wide limits without essentially changing the character ofthe device, The proportions hereinshown are those which now seem to me to be best adapted to secure the best average results under allconditions.

The system of levers described controls thev position and operation of the buckets, and any desired means for opening and closing the .buckets may be employed. The means herein shown are those which are now pre; ferred by me.

The closing mechanism is as follows: To

the sides of the main levers B and preferably as" near to the buckets as conditions will pera cable L has one end secured to a lever and is then reeved over the pulleys I, passing alternately from one side to the other and then finally over a pulley J, journaled on a main lever near its upper end, or, if desired, upon the shaft (3. This system of pulleys and cable is duplicated upon opposite sides of the device and forms a powerful closing mechanism. Its power and speed may be varied by increasing or decreasing the number of pulleys used and the number of runs of cable extending between the two sides.

The opening mechanism shown consists of cables 0, which are secured by one end to the main pivot-shaft O and pass over pulleys K,.carried upon the pivot-shaft H. It will be seen that the triangular levers E and the upper part of the main levers A form a powerful toggle, by lifting upon' which the main levers are swung outward to dump the buck- I ets and to put them in position for loading.

I have shown bars Mas placed outside the pulleys I, said bar forming a support and protection for the pulleys and also insuring retention ofthe cable L in place.

mit are journaled sheaves or pulleys I, and I I It is evident that the triangular levers E I are, in efiect, only-bell-crank levers,,and except that they would be "weakened thereby any one of their sides might as well be dis- Densed with.
