DUST BAG Filed March 5, 1929 Patented Oct. 17, 1933 UNITED STATES DUST BAG Harold C. 'Purdy, Akron, Ohio, assignor to The Hoover Company, a. corporation of Ohio Application March 5, 1929. Serial No. 344,273
4 Claims.
This invention relates to dust bags for electric suction cleaners and particularly to means for closing the discharge openings in dust bags.
A convenient means for closing the opening in a dust bag is the application of a fastener of the type which is known under the trade name of Hookless or Zipper. Fasteners of this type have proven more or less unsatisfactory as they are not air tight. Flaps which overlap each other have been provided on the inside of the bag to form a seal across the fastener but this construction has proven unsatisfactory because it was impossible to get the flaps to register properly to form a positive seal. Usually the flaps had to be guided by inserting the hand through the bag opening but often the flaps were left to come where they may and sealing of the opening was dependent upon the air pressure in the bag to force the flaps against the fastener to seal it. This flap arrangement did not prove successful because the flaps would not properly overlap each other and dust would escape through the fastener.
The primary object of the present invention is to provide means for guiding the flaps so that they will be properly positioned relative to each other and to the fastening member at all times.
Another object of the invention is toprovide means on the fastener and manipulating means to guide the flaps to proper position during opening and closing of the fastener.
Another object of the invention is to provide a tongue on the fastener manipulator for guiding the inner flaps so that they will always be maintained in proper position and thoroughly seal the opening when the bag is closed.
Other objects and advantages will hereinafter appear.
In accordance with the invention, the fastener manipulator or operating mechanism is provided with a tongue which extends down into the bag opening and has engagement with flaps which are sewn inside of the bag so that the flaps will be guided and overlap each other to provide a positive seal across the fastening area.
The accompanying drawing illustrates a selected embodiment of the invention and the views therein are as follows:
Fig. 1 is a detail plan view of a bag and fastener embodying the invention.
Fig. 2 is a detail sectional view thereof.
Fig. 3 is a side view of the fastener manipulator showing the tongue which guides the flaps.
Fig. 4 is a longitudinal sectional view showing a similar device applied to an end opening bag.
Referring to the drawing, 5 designates a dust bag or other objct having an opening or slit 6 which is adapted to be closed by a two strip fastener 7. A fastener manipulator 8 is provided for operating the fastener to open and close the bag. The fastener is applied to the dust bag by sewing the fabric edges 9 and 10 of the fastener to the edges of the bag on each side of the slit 6. A tongue 11 is secured to the lower side of the manipulator and extends down into the interior of the bag. This tongue is curved to form a slot, or groove 12 into which is threaded a flexible fabric flap 13 that is secured to the inner side of the bag.
Another flap 14 made of substantially stiff fabric is sewed on the inside of the bag'and on the side of the opening opposite to that to which the flap 13 is secured. This second flap'forms the other part of the seal and it passes below the tongue so that during operation of the manipulator, the flaps are maintained in proper relative position to each other and to the fastener. The flaps being stitched to the edges of the opening 6 will thus be forced outwardly against the fastener when there is air pressure in the bag. The groove in the tongue, and the. bottom of the tongue, guide the respective parts of the seal into a definite position relative to the edges of the opening 6 so thata proper seal is maintained across the fastener at all times when the bag is closed. 7
The bag may be secured to the handle of a suction cleaner in any particular manner but it has been found preferable to provide loops or other means to which any convenient supporting member may be attached, but which are preferably the type as shown in Patent No. 1,612,999, issued to Harry B. White, January 4th, 1927. The invention provides a positive seal for dust bags which are opened and closed by a fastener of the type disclosed, whereby the flaps or sealing elements are automatically controlled by means of the fastener manipulator.
Changes may be made in the form, construction and arrangement of the parts without departing from the spirit of the invention or sacrificing any of the advantages thereof and the right is hereby reserved to make all such changes as fairly fall within the scope of the following claims.
I claim:
1. In a dust bag having an opening therein, fastening means secured on each side of said opening, a manipulator for operating said fastening means to open and close the opening, said has having a pair of over-lapping flaps on the 2 g .o inside thereof and adapted to extend across the opening when the fastening member is closed to form a. seal across said opening, and a tongue secured to said manipulator and engaging said flaps to guide the same relative to each other.
2. In a dust bag having an opening therein,
fastening means secured to each side of saidopening, a manipulator for operating said fastening means for opening and closing-said opening; a tongue secured to said manipulator and having a groove therein, a pair' of over-lapping flaps on the inside of said bag;one efsaid flaps enga in in the groove. in the tongue and the other flap contacting with the lower sideof said tongue whereby said flaps are guided to lapped position when the opening is closed.
3. A receptacle having an opening therein, slot engage and disengage the same; a flap for forming a seal across said opening and means on said operating means having an opening in which said flap is engaged for guiding said flap to a position overlapping said opening.
