serial No. 383.001.
Td all whom t muy concern:
Be. it known that LNAL'ri-:ii L. citizen ofthe United States, and a resident of the city, county, and State of New York,
and useful lmprovenients in Paste-Tubes, of which the following is a specification.
This invention relates tof'that type of receptacle which comprises a-rigid tube adapted to contain a viscous orhporwdery material and provided with a piston and piston-operating means for expelling such material through its outlet, my invention being iutended to improve upon prior receptaclesI of this type in certain particulars which will be hereinafter explained.Vvrv
In the accompanying drawings, Figure 1 is a central, longitudinal section throughv a receptacle embodying a preferred forni of my invention, partially emptied of its contents; and Fig. Q is a similar view showing a slightly-n'ioilitied construction.
Referring to Fig. l of the drawings, the receptacle therein illustrated comprises a rigid tube 2 which vis preferably cylindrical in form and is usually drawn from a single piece of thin sheet metal,` said tube being permanently closed at one end, except for an 3, and provided with a cap 4 for! dosing its Opposite 0,. 1.9m, end iter the contion aboye described that the outlet from' been plncgd thm-Qin the tube is automatically closed at the end of each operation by which any outlet tents of the tube have lVithin the tube '2 is located a piston which may conveniently consist of a disk of cork 5 making a close sliding of the tube and provided with a stittening metallic disk or backing t5, operating rod 7 passes through said pistou and extends longitudinally within At their vided with conforming surfaces constituting a valve whereby the outlet 3 may be closed bv `forcing said rod forward, the ai'rangenient being such that said rod may be moved backward through the piston in an eudwise direction, then forced forward will carry the piston with i't. To this end, according to my preferred construction, the rod 7 is screwthreaded and has a with the ,disk t3, and its rear end passes through the cap 4 and is provided on the exterior of the latter head or thumb-piece such as a flat disk 8 rigidly secured thereto. Said rod passes freely through the cap 4t, as distinguished CLARK, a i
fit-with the interior 1 and a pistontube, so that there out of the coii'ipletcly-filled space in front.
the tube, i
without moving the latter, and if 4'the rear end ofthe tube moved backward, rod be turned in such direction to'tend threaded engagement i with an ol'iei'ating;
from having an internal bearing on the same. so that it is capable of 'being moved longitudinally through the cap without r otation, aud the parts` should be so proportioned that when the front end of the rod T is seated at the. outlet 3 the disk 5% will be just out of contact with the cap 4. thus providing for the tight closing of said outlet.
c As thus constructed, when it is 'desired to expel any of the contents of the tube, the
rod 7 is rotated in such direction as to cause it to travel ybackward through the piston 4, thepistou being prevented from rotating by its frictional engagenient with the tube. By such backward movement of the rod the outlet 3 is opened. and said rod is then forced directly forward, without rotation, carrying the piston withv it and'thereby expelling a certain amount of the contents of the tube. according to the distance through which said rod has been screwed backward through the piston. At the end of this forward movement the front end of the rod closes the outlet and prevents further expulsion of the contents of the tube untilthe operation above described is repeated.
It is one of thefeatures and through the cap of the construcportion of the contents of the tube is expelled, and that this closure takes place in a forward direction, that is to say, from is no danger ot' its forcing of the piston any surplus material which would have to be sul'iscquently removed and wasted, thus overcoming a defect which has of the described construction that it provides an absolutely tight closu re for the tube i when first filled and during transportation, time located at. and cannot be if the threaded since the piston'is at that so that to screw it forward through the piston the latter will serve asa fixed nut therefor and will cause the front end of said rod to be 'forced firmly against its seat'at the outlet. This requires that the cap be tightly secured to the tube, which is'preferably accomplished by providing a close driving tit the inside of the` ameter, as at between said parts. My construction also enables the user to expel with accuracy any desired quantity of the contents of the tube, since such quantity will evidently depend upon the distance through which the threaded rod is moved backward with respect to the piston before forcing it forward, as previousl)7 stated. y
The modified construction shown in Fig.
D o 1s more particularly intended for use z as a reservoir for fountain brushes and the like, to which end the front end of the tube 2 is provided with an elongatedoutlet nozzle 3 and that portion of the rod 7 which is located witiiin said nozzle is reduced in di- 9, to provide a free passage for the material between itself and the nozzle. At its rear or opposite end said rod is shown as provided with a slightly different form of thumb-piece, consisting of a metallic knob 8 castupon the end of the rod,- the construction being otherwise the same as that shown in Fig. 1 and the mode of operation being the same in each case.
In a prior application for U. Patent filed by me on the 19th day of January, 1907, Serial No. 352,697, I have'described and claimed a receptacle having a i piston and a threaded rod for operating the same, and so constructed that said rod is capable of passing freely through the rear end of the receptacle without rotation, and I therefore do not claim broadly such an ararangement herein, as my present invention relatesinore particularly to the employment of a plston-operating rod which will 'serve' lto close theoutlet from the receptacle at the end of itsfmovement forwardly, or in that direction which operates the piston, and it is to be understood that the particular constructions herein described whereby this result is accomplished may be modied in Va-' rious respects without departing from my invention.
I claim as my invention 1. A receptacle of the character described,
S. Letters 2. A receptacle of the character described, comprising a rigidtube provided at one end with an outlet and having its opposite end closed, a piston mounted to slide in said tube, and a screw-threaded rod passing thrugh the piston in threaded engagement therewith and adapted to move longitudinally without rotation through the closed end of the tube, said rod and tube being provided with conforming surfaces constituting a Valve for closing said outlet.
l' 8. A receptacle of the character described, comprising a rigid tube having at one end an elongated nozzle terminating in an outlet, a piston mounted to slide in said tube, and a piston-operating rod movable longitudinally within the tube and adapted to t outlet at the end of its forward movement, (that portion of the rod which is located within the said nozzle being reduced in di-4 ameter. I
4. A receptacle of the character described, comprising a rigid tube having at one end yan elongated nozzle terminating in an outlet, a piston mounted to slide in said tube, and a screw threaded rod passing freely through and engaging the piston and movable freely7 through the rear end of the tube, said iod 1 being adapted to close the outlet from lthe tube when moved forward therein and being reduced in diameter within the said nozzle.
