RICHARD V. PARR, OF FORDWICK, VIRGINIA.

BAG-HOLDER.

To all whom it may concern:

Be it known that I, RICHARD V. PARE, a citizen of the United States, residing at Fordwick, in the county of Augusta and State of Virginia, have invented certain new and useful Improvements in Bag-Holders, of which the following is a specification.

My said invention consists in an improved construction and arrangement of bag holders and fillers for use in connection with separators or other machines from which any substance is fed into bags, relating particularly to that particular form of bag holder forming 4the subJect matter of my former Letters Patent No. 756,693, of April 5, 1904, whereby the holder may adjust itself to bags of varying sizes and be held therein under suitable tension, and whereby the flow of material may be shut off or regulated as desired by the operator in a convenient manner, all as will be hereinafter more fully described andclaimed.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts, Figure 1 is a side elevation of a bag older of my improved construction with its parts in the position they occupy when expanded, as when a bag is thereon and the apparatus ready for use, the valve being in open position, Fig. 2 a similar view with the parts in the position they occupy when a bag is to be placed. thereon or removed therefrom, the valve being in closed position, Fig. 3 a vertical section on the dotted line 3 3 in Fig. 5 with the parts in the position shown in Fig. 1', Fig. 4 a transverse vertical section on the dotted line 1 4 in Fig. 5, and Fig. 5 a top or plan view.

In said drawings the ortions marked A represent the chute or delivery pipe through which the material is fed, B the stationary side of the bag holder and C its hinged side.

The chute or delivery pipe Ais preferably screw threaded at its upper end for attachment to the delivery pipe leading from the machine. Near its u er end it is provided with a circumferentiafffange or collar a. Its lower end is formed convex in cross section and has a valve A1 `of corresponding form mounted to swing upon supporting arms al vand adapted to cover said lower end. Said arms al are hinged on afshaft 1 which extends through hollow tubular bearings 2, which are mounted in aperturesy in op osite sides of the pipe A and extend towar .s the center` thereof. Said arms are fixed rigidly` Specification of Letters Patent.

the pipe A and are connected at their outer ends by a handle a3. An agitator 1,4 having arms a5 which extend each way therefrom, is mounted on the center lof shaft 1 between the ends of bearings 2 and serve to prevent the permanent lodgment of material upon said bearings. The arms a2 are secured in the position best illustrated in Fig. 3 so that when they are in the position shown in whole lines in said figure, the valve A1 will be in closed position and when in the osition shown in dotted lines, the valve w` be open, in the position shown by dotted lines. The handle a3, will in all instances be at one side of the pipe A and on that side occupied by the at- The valve plate A1 is preferably mounted on the lower ends of the arms al by means of a central supporting screw s and adjusting screws s1 on each side thereof, as best shown in Fig. 3.

The side B of the bag horlder is secured at its upper end around one side of collar a on pipe A, and extends down to beneath the lower end of said pipe A.

The side C is hinged at its upper and inner corners on intles c4 to the side B and is adapted to 't, when in the position shown in Fig. 1, around a depending fiange c which extends downwardly from a top C1, which top is of suitable shape and is secured to the flange a and extends outwardly from the side of pipe A to cover and closeV the top of the bag holder proper. Said flange c inclines inwardly from its outer edge towards said pipe A, as shown most clearly in Fig. 2, in order to permit the ready operation of the part C upon its hinges.

Levers 5 are pivoted on bolts 6 to the opposite sides of the pivoted section C and extend to one side ofthe apparatus and are connected at their outer ends by a handle 7. Curved links 8 are pivoted on bolts 9 to each of said levers 5 a short distance from the pivots 6 and are connected at their outer ends by a bolt 10 which extends through horizontal slots in the sides of aiU-shaped bracket 11 which is secured firmly to the outer side of the rigid section B. A coiled spring 12 is interposed between said bolt 10 and the outer end of said bracket 11, surrounding a pin 13 which is inserted through a perforation in the outer end of said bracket and has a transverse perforation near its inrepeated.

ner end through which said bolt 10 extends thereby retaining the parts in position.

In operation, the parts being in the position shown in Fig. 2, the bag is placed over the lower end of parts B and C which` are then expanded by forcing down the levers 5 by means of the connecting handle 7, which operates to throw the lower end of the hinged part C outwardly on its hinges c4 until it reaches the position, or approximately the position, shown in Fig. 1, the bolt 10 connecting the outer ends of links 8 being allowed to slide in the slots in the sides of the bracket 11 to adjust the size of the holder to the size of the bag, the spring 12 serving to hold the bag holder in the mouth of the bag under sufficient tension Whatever its size. The bag being in position the valve plate A1 is opened by throwing the levers A2, by means of the handle A3, from the position shown in Fig. 2 and by whole lines in Fig. 3 to the position shown in Fig. 1 and by dotted lines in Fig. 3, which opens the lower end `of pipe A and permits the material to flow When. a sufficient quantity has been allowed to flow into the bag, the valve is closed by elevating the handle a3. The bag holder is contracted by elevating `the handle 7 when the bag may be removed,

:another put in its place, and the operation The valve plate A1 is adjusted to fit properly upon the lower end of pipe A by a proper adjustment of the supporting screws s and the adjust-ing side screws s1, as

will be readily understood.

By reason of having the handle 7 and the `handle A3 arranged on the same side of the device and adjacent to each other, the oper` ator is enabled, without changing his posi tion, to operate the valve and hinged section, one with either hand, as required, thus adding materially to .the 'convenient arrangement and perfect operation of the device.

Having thus fully described my said invention, what lf' claim as new and desire to secure by Letters Patent, is,

1. A bag holder comprising a closed top, a fixed section on one side thereof, a hinged section on the other the edges of which overlap the edges of said iiXed section, said vhinged section being provided with a closed top, levers pivoted to one section and connected by links to the other, and a yielding vconnection between said parts, whereby the size of the bag holder when expanded may adjust itself automatically to the size of the bag, substantially as set forth.
