FILLING DEVICE.

To all whom it may concern:

Be it known that I, HORACE W. \VARD- WELL, citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Filling Devices, of which the following is a specification.

This invention relates to filling devices particularly adapted and intended to be used for filling ink wells.

It comprises a flexible tube one end of which is attached to an ink can and the other end of which is provided with 21v pair of pincers, so that for instance in filling ink wells in a school a person can go from desk to desk and fill the wells by releasing the pressure on the pincers which allows the tube to open and permits the ink to flow, and when each ink well is filled the pressure on the pincers is released, thereby immediately closing the tube and preventing any dropping or spilling of ink on the desks. By the means described a number of ink wells or small receptacles may be quickly filled.

Although particularly useful in connection with ink wells the invention may be also applied for dispensing liquid from oil cans or any other kind of liquid-containing vessels. No limitation with respect to the use of the device is implied.

The principal feature of novelty in the case resides in the pincers or device used to control the flow, inasmuch as I am aware that it is old to discharge liquid from a vessel through a rubber tube.

The invention is illustrated in the accompanying drawings in which- Figure 1 is a perspective view of the device. Fig. 2 is a longitudinal section. Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. a is a section on the line a-a of Fig. 2.

Referring specifically to the drawings, 6 indicates a can, tank or other container which holds the supply of liquid. A rubber tube 7 leads from this can, and terminates in a nipple 8 having preferably a small opening to prevent dripping and give a convenient flow of liquid. The tube passes through or between the members of a pair of pincers which are normally closed and clamped upon the tube to collapse and close the same and prevent any flow therethrough. The pincers comprise two members pivoted together at 9, one member, 10, being curved Specification of Letters Patent.

or recessed to form opposite side flanges 11 between which the other member 12 works. These members are extended rearwardly to form handles, and the jaws of the members are normally pressed together by a spring 13 coiled at the middle around a pin 1 1 extending across between the sides of the member 10 and bearing at one end against the member 10 and at the other end against the under or inner side of the member 12. At the front end or jaw of the member 10 its flanges 11 form a groove or recess through which the tube 7 extends, and said flanges serve to confine the sides of the tube, as shown in Fig. 4. The jaw of the member 12 works between said flanges, as indicated at 12 and substantially fills the space between said flanges, so that when the pincers are closed upon the tube said tube is confined on all sides and is completely collapsed. In order to hole the tube in fixed position with respect to the pincers it is passed through ahole at 16 in the handle of the member 10, said hole being slightly offset so that the tube binds against the edges thereof and hence cannot slip or be moved except by a special effort.

In the use of the device the pincers are held in the hand and serve to direct and control the tube. B y pressure on the pincers they are opened, and the liquid will flow. When the pressure is released the spring 13 closes the pincers and shuts off the flow by closing the rubber pipe. The pincers thus serve not only to control the flow, but give a convenient means for holding and manipulating the tube so as to direct the flow, and enable the nozzle or nipple to be placed at exactly the position desired, and the flow can be started or stopped Without changing the position of the nipple, and by the use of one end only, thereby avoiding the objections incident to collapsing the tube between the fingers, or kinking the same. In short, the pincers form both a holder and cut-off for the tube, capable of convenient manipulation and instant control.

I claim 1. The combination with a collapsible discharge tube, of a pair of pincers thereon, one member of which has longitudinal side flanges and the other member of which is pivoted between said flanges, forming a longitudinal passage between the members of P the flanges, through which passage the tube extends lengthwise of the pincers, a pm extending across between said flanges, and a spring coiled around the pin and bearing at opposite ends against the respective members of the pincers, one end of the spring lying closely beside one of the flanges, out

of the way of the tube.

2. The combination with a collapsible discharge tube, of a pair of pincers thereon, consisting of members pivoted together and each having a jaw and handle, one member being flanged at the side to form a longitul l l dinal passage through which the tube eX- tends lengthwise between the handles and jaws, and one handle having an opening through which the tube passes with frictional engagement.

In testimony whereof, I atlix my signature in presence of two witnesses.
