O F SAME PLACE.

SPECIFICATION formingpart of Letters Patent l\To. 665,361, dated January 1, 1901.

Application filed May 10, 1900.

T at whom, it may concern.

Be it known that I, JOHN W. BERRY, a citizen of the United States, residing at (513 North Cakes street, in the city of Tacoma, in the county of Pierce and State of \Vashington, (and whose post-office address is Tacoma. Washington,) have invented a new and useful Improvement in Automatic Weighing-Mar chines, of which the following is a specification.

My invention pertains to devices for weighin articles of merchandise preparatory to trade and commerce.

It pertains more particularly to improvements in my newly-invented automatic weighing-machine for which application for Letters Patent was filed February 27, 1900, Serial No. 6,708.

The objects of my improvement are to simplify the construction of my machine and to provide an automatic electrical means for operating the same. I attain these objects by means of the apparatus illustrated in the accompanying drawings, in which Figure l is a side elevation of my machine constructed with my newly-invented improvement. Fig. 2 is a left front view of the same.

Similar letters refer to similar parts in both views.

My invention comprises a wide wheel W, constructed with a number (preferably five) of triangular-shaped buckets between the sides or disks B and C, which, with the webs forming the triangular apartments, form the construction of the weighing-wheel. The wheel is mounted on the axis A between two upright supports G G, each of which is rigidly fixed to a base or platform F, designed to rest on the scales H. The upright supports G G continue up till above W and support the chute L, pivotally mounted at a. This chute is designed to receive material from the supply-chute D and fill each bucket of the weighing-wheel with an equal weight of the same, all of which is fully set forth in my former specification. As each bucket is filled with the required weight of material the wheel turns automatically and discharges each regularly into the discharge-chute E. The wheel during the filling of each bucket is held in serial No. 16,138. lNo model.)

equilibrium by the spring R, acting on the lugs d to (Z and the weighted arm S, resting on the lugs e to 6 alternately. The friction of the spring R and of the adjustable spring brake-beam N, acting 011 the projecting pins g to 9 cause the wheel to revolve steadily and to stop without jolting as each bucket comes into place to be filled.

My improvement comprises a small pivoted latch-hook I), mounted on one side of the swinging chute L. As the wheel W revolves this latch catches on the lugs 61 to d and draws the chute forward against the edge of the shelf M until each bucket is filled in its turn.

0n the shelf Z is provided an electric battery X, and on the shelf M is an electromagnet Y, properly connected with the battery, to be charged therefrom. One pole of the battery is connected by wire 19 to the scale-beam J at p. The opposite pole, by means of the wire it, is connected with the adjustable key at directly above the scale-beam J.

\Vhen one of the buckets, as No. 1, receives the desired weight of material, the scale-beam tips up and, coming into contact with the key it, the circuit is closed, causing the electro magnet to attract the end of the lever-arm t', pivotally mounted at Z. The opposite end of i is connected bymeans of the adjustable wire 713 to the latch-hook b, which is now instantly lifted, relieving the lug d, and allows the wheel to turn forward and bring bucket No. 2 into position. As soon as No.1 begins to empty into E the scale-beam tips down again and the circuit is broken, the electromagnet relieves the lever i, and the latch-hook I) again drops down in time to catch lug 61 and thus hold bucket No.2 in position until filled. In this way my machine can be operated cono tinuously for any length of time and Weigh the quantities rapidly and accurately.

By means of my improvement my machine is simplified in its construction, and being made in one combination complete in itself 5 it can be placed on any form or size of scales and operated without a special framework to adjust it thereto.

1 am not limited to detail in my electrical attachment, but retain the right to vary the form and proportions to best suit the size and character of my machine to obtain the desired result in the most practical manner.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. An automatic weighing-machine, comprising in combination with the scales, the rotary com partment-wheel, a pivoted feedin gchute, a pivoted latch mounted on said chute, the free end of which latch is disposed in the path of the projections about the circumference of said wheel, an electromagnet, and electric circuit adapted to be closed when a predetermined amount of m aterial is weighed in one of the compartments of said wheel, and said latch raised out of the path of said projections as the circuit is closed, as set forth.

2. An automatic Weighing-machine, com- JNO. WV. BERRY.
