Specification of Letters Patent.

Patented May 15, 1906.

Application filed April 8, 1905. Serial Ho. 254,647-

To all whom it may concern.-

Be it known that I Roemi'r D. Wane, a citizep of the United tates, residing at Mmden, in the parish of Webster and State of Louisiana, have invented certain new and useful Improvements in Automatic Wei hing and Dumpin Machines, of which the fo low- 111%!8 a spool cation.

ly invention relates to automatic wci hmfi and dumping machines, which may e di erently constrdcted, but preferably has many of the features of my application'for Letters Patent Scrial No. 245,571; and my invention consists in the arrangement of toggles in connection with scale-beams, each swin 'ng from the same axis, and in providin t e receptacles with movable bottoms or va ves and means for locking and openin the same, as full set forth hereinafter, an as illustrated in t c accompanying drawings, In whichhi re 1 is an elevation in art section of a merging and dumpin mac 'ne embodyin my improvements. lg. 2 is a sections an. 7 Within the mouth of the chute or hopper t, communicating with the source of'silpply, is centrally pivoted a valve I), having two faces divergm from the center downward, so that when t e valve is in one position the chute will be opened above a receptacle supported by one of two scales B B and when in the other position will be opened above a receptacle supported by the other scale. These scales may 9 pivoted in any suitable manner-as, or instance, in my application, SenalNo. 245,671-bnt referably the are suspended from a centre pivot or she I: a, supported by a main frame 0. Each scale conslsts of a beam 1 and may be provided with the usual suitable adjustable weights and munterwoi hts, as desired. Sus nded to the scale cams below the mouth of the chute at each side are receptacles m and m, which may be suitably connected. Thus each of the beams l ie connected to operate the valve 3), a hair 0 being connected to the {amt of a toggle r r and to the'scale-bea'm I Wit? and one member of the to gle being connected to an arm 9 on the sha t f of the valve, as illustrated, so that as either rece tacle sinks-as, for instance the receptac e m'--the connected toggles will be broken and the valve D will be swung to one side to close the chute above the descending rece tacle while the rising of the other reeeptac s will strai hten the toggle connected therewith and inter-pose its members in a straight lme between their pivot and the arm 9, so as to hold the valve D in its new position during the filling of the elevated receptacle. When the latter is filled, its weight will canse its dcseent, breaking the toggle to which the receptools is connected, a am shifting the valve, which will be secured in its new osition as the opposite receptacle reaches t a limit of its upward movement. It will be seen that owing to the connections shown as one receptacle descends its weight will be exerted to lift the other receptacle.

With the above-described parts are combined means whereby the material in each receptaclo, as soon as the latter has been propor y filled, will be discharged, and the titscharge from both receptacles is received by a chute E, or in an suitable way, from which it may pass to a ag held beneath or to any convenient receiver. As shown, each receptacle m m is of metal or other suitable rigid material and is 'rovidcd with a bottom 1;, hinged to one si e at w connterweighted, if necessary, and provider with anarm or extension it, between which and a pint on the receptacle is interposed a to gle s,and a link q extends from the joint 0 this toggle to a pin p, projecting from the beam Z at a point distant frorn'th'o point 1 where the receptacle is suspended by, the beam 1, so that as the beaml swings downward the pin will be carried down with the link q, moving more rapidly than the receptacle, thus breaking the toggle a and swinging the bottom 12 to an open position, where y the material in the receptacle is discharged. When the receptacle is again carried upward and the scalebeam takes a horizontal osition, the link q will carry upward the pivot of the toggles, bringing the two sections ercoi" into inc, and thereby locking the hinged valve in its closed position. It will be seen that this is a sitive movement alternately closing and coking the inlet-valve and alternately 0 ening and closing and locking the hinged )ottorns er the receptacles, so that as one fills the other discharges.

It will be evident that other forms of movable bottoms or valves vfor the receptacles may be employed, as well as other means for causing the same to be opened when the scale is tilted or otherwise moved on the reee tacle receiving its charge.

ithout limiting mysel to the precise construction and arrangement of parts shown, I l of a receptacle supported by each scale-beam claim as my invention 1. The combination in an automatic weighing-machine, of a chute, a valve at the mouth of the chute, two scale-beams having a common pivot below said valve and supporting receptacles, two toggles, each connected to operate the valve, and a link between each toggle and the scale-beam supporting the receptacle below said toggle, substantially as set forth.

'2. 'lhecombination in aweighing-machine, of a chute, a valve at. the mouth of the chute, two scale-beams pivoted at their inner ends and extendingoutward in oppositedirections, toggles connected with the frame and with the valve, and links connecting the joint of each toggle with the adjacent scale-beam, substantially as set forth.

3. The combination with a chute and with a valve hin ed in the mouth of the chute to open and close opposite sides thereof alternately, of two scale-beams, each having a long and shortarm, the short arm of each beam supporting a receptacle, a toggle, aml a link connecting the same with each short arm, said toggle connected to the frame and to the valve, substantially as set forth.

4. The combination with the valve and scale-beams of an automatic weighing and dumping machine, of a receptacle supported by each scale-bmim, and provided with a. movable bottom or valve, a toggle connecting the valve to the receptacle, and connections between the to glc and scale-beam whereby to open said va ve as the receptacle begins to descend when filled,snbstantiallyas set forth.

5. The combination with the chute, valve and scale-beams and receptacles of a wei hingmachine, of connections between the cams and valve for shifting the latter to open and close the mouth of the chute at opposite sides alternately, a bottom hinged to each receptacle and provided with an arm and with a toggle extending between said arm and a point on the receptacle, and connections between the to glcs and the beams whereby the sections 0 each toggle are brought into line as the receptacle rises and are carried out of line as the receptacle descends, substantially as set forth.

6. The combination of the chute, valve, scale-beams, toggles r r connected bv links to the beams, receptacles irovided with pivoted bottoms, toggles 8 am connections between the toggles a and the scale-beams, substantially as set forth.

7. In an automatic weighing and dumping machine, the combination with scale-beams,

and provided wit 1 a movable bottom or valve, and toggles connecting the receptacle and valve, and connections between the toggles and scale-beams whereby the valve is opened on the descent aml closed on the ascent of each receptacle, substantially as set forth.

S. In an automatic weighing and dumping machine the combination of the scale-beams, receptacles, a bottom hinged to each receptacle and provided with an arm and with a toggle extending between said arm and a point on the receptacle, and connections between the toggles and beams whereby the sections of each toggle are brought into line as the corresponding receptacle rises and are carried out of line as the corresponding receptacle desccnds, substantially as set forth.

9. In an automatic weighing and dumping machine, the combination with the main inlet-valve and scale-beams, of a receptacle, supported by each scale-bemn, provided with a movable bottom or valve, toggles connecting the valve to the. receptacle, and connections between the scale-beamsand the toggles whereby the bottom of each rece taclc is opened when the inlet-valve is closet and vice versa alternately, substantially as set forth.

10. In an automatic weighing and dumping machine, the combination of the scaleboams, receptacles supported by said scalebeams and provided with movable bottoms or valves having toggle connection with the receptacles, and connections between the toggles and the beams whereby the members of each toggle are brought into line as the corresponding rccc tacle rises, thereby closing the valve and locliing it in closed position, substantially as set forth.

11. In an automatic weighing and dumping machine, the combination of the scalebeams, receptacles supported by said scalebeams and provided with movable bottoms or valves having toggle connections with the receptacles, and connections between the toggles and the beams whereby the members of each toggle are carried out of line as the corresponding receptacle descends thereby opening the. valve and holding it in opened position, substantially as set forth.
