Bae-FILLING ianonnnrsir.

Application led September 25, 1915.

To all whom it may concern.'

Be it known that 1, EMIL F. ANDERSON, a citizen of the United States,residing at Chicago, in the county of Cook and State of illinois, have invented certain new and use ful Improvements in Bag-Filling Mecha nisms, of which the following is a full, clear,

and exact specification.

My invention relates to bag filling mechanism.

lt has among its objects to provide improved mechanism for filling a bag. A further obj ect of my invention is to provide improved means for holding a bag holder in its inoperative position. A still further object of my invention is to provide improved cooperating means for holding a bag and controlling the discharge port. l attain these objects by an improved construction including improved means for supporting the bag operatively connectable in an improved manner and preferably interlocking with improved means controlling the dis` charge of the material to be bagged.

ln the accompanying drawings have shown, for purposes of illustration, one embodiment which my invention may assume in practice, the same being shown as applied to the grain box of a stripper or harvester thresher.

1n the drawings:

Figure 1 is an end elevation pf my improvement;

Fig. 2 is a side elevation; Y

Fig. 3 is a detail view of the bag holding member.

In the construction illustrated, a grain box or reservoir 1 is provided with a discharge outlet or opening 2 in its side wall controlled by a vertically movable gate 3 reciprocable in guides 4L. This gate 3 is pivotally connected to a normally vertically disposed link 5 having a laterally inclined upper end pivoted on a depending operating lever 6 pivoted at its upper end at 7 upon the upper part of the boX. This operating lever 6 has a downwardly inclined laterally disposed handle portion 8 extending therefrom at a point below the pivot of the link 5. This handle portion is preferably provided with an upturned free end and a notch 9 at a point adjacent its end adapted to engage with a transverse member 1Q, preferably in the form of a roller, carried between the parallel arms of a U-shaped han- Specification of Letters Patent.

dle 11 formed on and extending laterally from the bowed end of a 'll-shaped bag hold ing member 12 which is pivotedat 13 on opposite sides .of the bottom ofthe opening 2 in a manner hereinafter described. As shown,the bag holding member 12 prefer'- ably conforms substantially to the shape of the bag mouth and is provided with a plurality `of hooks or teeth 1li thereon adapted to be punched throughthe material of the bag in such a manner that the latter may be supported thereby, these teeth 1A preferably being disposed around the curved portion of the member 12 and also being provided on the ends ofits arms,` As shown, a platel, preferably having a fiat upper surface and an inclined side, is also carried upon each arm of the member 12 and entends upward therefrom These plates 15 act as bearings for the pivot 13, give very desirable clearance, and also act as limiting means, the inclined surfaces `thereof engaging with stop members 16 extending downwardly from the box 1 at apoint beneath theopening 2 and thereby limiting the downward movement of the member 12, while their flat upper surfaces engage with the end of the box to limit upward movement of the member 12.

Until it is desired to fill a bag, the parts occupy the compact, folded or inoperative position shown in full lines in Fig. 1, wherein it is to be noted that the gate 8 is down and the `bag holding member 12 is in vertical position and locked therein by the engagement of the notch 9 on the controlling member-6 with the roller 1() on the handle 11. When it is desired to fill a bag, the handle portion of the controlling member 6 is raised to such an extent as to disengage the notch 9 from the roller 10 but not to open the outlet 2. rlhe bag holding member 12 then drops down, or is lowered by gripping the handle portion 11 thereof, until it occupies the position shown in dotted lines in Fig. l, the downward movement of the same being limited by engagement of the plates 15 with the stops 16. ln this position of the parts the bag may be readily attached to the teeth 111-. l/Vhen this has been done the handle 8 of the gate 8 is raised to permit grain to flow through the opening 2 into the bag.

Attention is directed to the fact that, in my improved construction, while a bag is being filled, the controlling member 6 may be adjusted about Vits pivot to the position shown in Fig. l and held therein in a Welllnovvn manner against an accidental returi movement due to its shape and to the displacement of the centers. dent that this controlling member 6 may be operated Whenever it is to open or close the outlet desiredA and that When no further bags are to be lled for the time, or it is desired to reduce the Width of themachine for any reason, the -parts may be readily returned to the compact, folded position shown in full linesin Fig. 1 and automatically locked Vtherein by pulling down the member 6 and raising the bag holder, the curved `end of the handle 8 on the controlling member 6 passing between the sides of the handle 11 on the bag holder and sliding over the member l0 until the latter is seated in the notch 9 and the parts are thus rinterlocked.

While l have in this applicationspecifically described one embodiment which my invention may assume in practice, it is, of course, to be understood that this form is used for purposes of illustrationV and that the invention is not limited thereto but may b e embodied in other forms.

TWhat I claim as my invention, and sire to secure by Letters Patent, is:

l. In a bag Elling mechanism, a reservoir having an outlet, outlet opening and closing mechanism including an operating lever, and a bag holder pivotally supported beneath said outlet engageable with said lever when in inoperative position and movable into operative position upon manipulation of said lever.

2,-ln a bag'filling mechanism, a reservoir having an outlet, outlet opening and closing mechanism including an operating lever, and a bag holder pivotally supported beneath said outlet'engageable With said lever when in inoperative position and movable into operative position upon manipulartion of said lever and prior to the opening of said outlet. A Y

3. ln a bag filling mechanism, a reservoir having an outlet, outlet opening and closing mechanism including a pivoted operating lever having a notch therein, and a bag holder pivoted on said reservoir be* neath said outlet and having a portion at one side lof its pivot engageable with the notch in said lever when said bag holder is raised to inoperative position.

et. In a bag filling mechanism, a reser- "fvoir having an opening therein, sliding door `mechanism for said opening, a lifting lever for said mechanism pivoted to said reservoir above said door and operatively connected to the latter, a bag holder pivoted to said reservoir beneath said door, and means whereby said bag holder may be locked in inoperative position by said lifting lever.

5. ln a bag filling mechanism, a reservoir having an outlet therein, outlet opening and closing means including a lever pivoted on said reservoir above said outlet, said lever having a notch in one end thereof, and a bag holding member pivoted to said reservoir beneath said outlet having a vlaterally extending handle member engageable with said notch when said bag holding member is raised to vertical position.

6. In a bag filling mechanism, a reservoir having an outlet, outlet opening and closing mechanism including a pivoted depending lever having a curved notched end, and a bag holder pivoted on said reservoir beneath said outlet and having a portion at one side of its pivot automatically engageable with the notch in said lever as said bag holder is raised to inoperative position and releasable therefrom upon elevation of said lever.

7. In a bag filling mechanism, a reservoir having an outlet, depending stop inembers disposed on opposite sides of said reservoir at points beneath said outlet, a bag holder pivoted to said reservoir at points in front of said stop members having depending shoulders engageable with said stop members and a laterally extending handle, a reciprocating door for said outlet, a link pivotally connected to said door, and a door lifting lever pivotally connected to said link and pivoted to said reservoir at a point above said pivotal connection, said lever having an angularly disposed outer end provided With a notch automatically engaging the handle of said bag filling member as the latter is moved toward inoperative position.

In testimony whereof I aliix my signature.
