VALVE BAGU Specification of Letters Patent.
Patented Jan: 16, 1906.
Application filed February 2, 1903. Serial No. 141,549.
To all whom, it may concern.-
Be it known that I, ADELMER M. BATES, a citizen of the United States,'residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Valve-Bags, of which the following is a specification.
My invention relates to valve-bags, and has for its object to provide certain new and useful valve-bags and improvements therein, as hereinafter described and referred to.
I have illustrated my invention in a dia grammatic manner, and in the drawings Figure 1 is a bottom view of the bag in a partially-unformed state. Fig. 2 is a similar view with the parts folded in upon each other to com lete the bag. Fig. 3 is a cross-section on inc 3 3, Fig. 2. Fig. 4 is a longitudinal section on line 4 4, Fig. 2. Fig. 5 is a similar view with the parts shown in their position durin the filling process. Fig. 6 is a detail View the parts illustrated in Figs. 4 and with the filling-tube removed. Fig. 7 is a view of a bag-tube with the valve extensionpiece in the lposition which it would occu y if applied to t e tube before the folding is one. Fig. 8 is a detail cross-section on line 8 8, Fig. 7.
Like parts are indicated by the same letters in all the figures.
A A are the side portions of the ba which in the case illustrated is made wit a so called satchel-bottomthat is to say, the
'bag-tube'being collapsed so that the side poreach other, and then when the parts are pasted together-it will be seen that the bottom is com letely formed. Such bags are commonly tiius finished at the bottom, and the material is then put into the bag and the bag is tied at the top. In the case shown here to illustrate my invention Fig. 1 indi-- cates the up er portion of the bag, the lower ortion of w ich has already been completely ormed so as to be completely closed. A piece of material F, sha ed as shown and adapted to form What I s all call an extension-valve, is now inserted between the two pieces 0 C and the piece B, as indicated, and
when the pieces are folded together it is obvious that the piece of material Fpwill be folded up with the portions OC of the bag. .5
This is illustrated in Fig. 2, where the parts have been so brought together. The parts in this process of folding are gummed to a certain extentthat is to say, the left-hand portion of one part C'is gummed and folded over onto the art B and the inner portions and parts" O The other part C is now gummed along its whole len th and folded on top of the first part C, and t us the parts are all brought together in theposition shown in Fig. 2; but'there is an opening through the folded portions of the material F, and this is the valve-opening protected by the collapsible extension-valve part F. The filling-tube G is shown as inserted through this opening. The tube G may be supplied with spreading ribs G or any structure which will tend tokeep the valve-opening open or partially open-about the tube, and the arts arepreferably so related that the va ve-openmg is- This piece can be gummed or secured in any desired manner ,jif such securing is found necessary, to the bag portionswhen it is put in place, as indicated inFig. 1.
When, theparts are folded together as indicated in Figs. 2 and 3,they are arranged so that on a cross-section of Fig. 3 the first fold of material, beginning at the top, is one of the parts C, the next is the'eXtension-pie'ce F, the next is another art C, the next is the extension-piece F, 'un er which lies the tube G, and at thebottom is again the extensionpieceF.
As previously suggested, the arrangement of parts here shown is to be taken merely as diagrammatic and not in any sense as limiting me to the particular form and arrangement here illustrated.
The use and operation of this invention and its advantages I will now proceed to suggest in part. Inthe first place, I can thus provide, by means of this flexible extension, a paper or other bag practically impervious to air with a suitable valve device. This valve device may of course be of any desired material and the same or a diflerent material from that of the bag proper; but in the ordinary form of the device there will be a paper bag, such as the ordinary paper flour-bag, accompanied by the inwardly-extending flexible cloth-formed valve. In the case of such bags, where they are filled by means of a tube or by a narrow stream, it is obvious that the opening through which the filling takes place should be larger than the filling-tube, so that the air within the bag can escape around the tube. This would not be true, of course, if the sides of the ba were not impervious to air. Thus with a c oth'bag the valve might fit closely around the tube. With a paper bag it ought not to do so; but if the opening is lar er than the tube then the escaping air will carry with it a quantity of flour or other such material as may be in the process of being filled into the bag. which I employ should therefore be in most cases of a nature to permit the air to pass,
but so as to act as a screen and prevent the powder or flour from passin with such currentof air. Thus the flexib e or cloth valve of a paper bag, such as illustrated in Fig. 5, will close around the tube and act as a screen, permitting the air to pass out, while at the same time preventing the escape of flour or other material.
The valve-opening may be expanded and ke t open by the ribs G G, shown on the tu e, though of course any other sort of extending device could be used and it could be separate from or attached to the tube, as desired. The extension-valve device can be formed of any small piece of material and in ordinary practice would be made of waste or scrap material. I
In orderto get the long inwardly-projecting valve, it would be necessary, whatever the material, to fold down the parts B B of the bag-tube so as to bring their ends inwardly toward the center or middle line of the bag; but when this is done then the bottom of the bag becomes wide, and this is the manner in which such bags are frequently made. By my construction I am enabled to get a long opening for the valve-opening with a narrow bottom and top for the bag, and thus can produce a bag to hold a given weight of material with a shorter tube than if I endeavored to obtain the valve feature without the addition of the extension-piece. Thus in a case where the material of the bag was a proper material to form a valve I could get such valve-open ing without any extension-piece; but in that event I should have to use a lon er bag-tube,
and thus would have a great eal of waste material. 1 At the same time the valve-o en ing would be correspondingly widene so The flexible material,
the length of the opening would be oflset by .increasing its width. By the method here shown I obtain a long and narrow opening into the bag, and when this opening is pro tected by the inward extension it becomes very effective as a valve.
There is another feature of great advantage in my device, and that is this: the valve extension-piece F would naturally be made of suitable material to form a valve, and this would be important if it were associated with a bag the material of which was not suitable for such valve. If, for example, I had apaper bag, it is obvious that the two faces of paper coming together would not make a good closure; but if to this I add the valve exten sioniece F of cloth then when the tube is with rawn the two faces of cloth come together, as indicated in Fig. 6, and form a very complete closure. I can make any size of valve'I desire by this means by simpl varying the length of the extension-piece and I can foldit into the material while the bag is in the process of being formed or otherwise. 0
Moreover, it greatly strengthens the bag, if the same should be made of weak material, about the point where the material is introduced into the bag, which of course is the very woul need strengthening.
My arrangement is peculiarly valuable in the case of bags upon which printed matter is placed, for obviously when the bags are tied at the top a large part. of the upper portion of the bag is creased and wrmkled, so as to greatly reduce the area suitable for printing. It is not uncommon for bags of this nature bearing the printed brand of wellknown manufacturers to be untied and emptied and 10 5 to be then filled with an inferior grade of material. This can be prevented b the use of my bag, for the printed matter wi l come'near the top, and the structure of the bag is such that it has practically to be destroyed in or- 1-10 der to be emptied, and any attempt to close it again would necessarily result in revealing the fraud.
The valve extension-piece may be of the same or difierent material as compared with It 5 when the bag is filled. It may be secured in any desired manner by pasting or by gumming or sewing and at any desired time durr25 ing the process of the making of the bag or at other times, accordin to the form of the bag. It may be made 0 waste material and any-sized bag can be used. The result is a bag narrow at the top and bottom, with an inoint where such weak-material bag 95 It results 1 2o creased printing area and with a reinforcing or strengthening effect about the valve-opening, and it renders the reuse of the bag diflicult, if not impossible. r
The valve extension-piece surrounds the valve-opening, and thus strengthens it at all points, and might be used without any material extension to form a valve proper, but simply to serve as a binding or strengthening part for the opening between the walls of the ag itself.
