Application June 26, 1933, Serial No. 677,555

retaining therein all the dirt and 'dust particles collected by the sweeper or vacuum cleaner.

The primary object of the present invention is to provide a novel and improved bag construction for a suction sweeper or vacuum cleaner in which the dirt collected by the 'sameis accumulated in the upper end of the bag and maybe discharged therefrom without removing the bag from th sweeper or vacuum cleaner.

A still further object of the invention is to provide a novel and improved bag construction in which a pocket is provided in the upper portion of the bag by sewing therein a partition wall in the upper end of the bag and providing a support across the intermediate portion of the bag so that thebag will fold in the center thereof when detached at the upper end from the handle to discharge the dirt from the pocket at the upper end of the bag.

A still further object of the" invention is to provide a novel and improved bag construction for a suction sweeper or vacuum cleaner in the form of a pocket located at the upper end of the bag so that the dirt collected by the sweeper or cleaner is accumulated at the upper end of the bag and away from the lower entrance or conmotion of the bag with the cleaner proper and arranging the entrance to the pocket in alignment with and on thesame side as the entrance of the dirt collected by the sweeper as it passes from the cleaner proper into the bag.

A further object of the present invention is to provide a'novel bag construction for a suction cleaner in which the dust and dirt is collected at one end thereof away from the entrance of the dirt into the bag therein preventing the clogging of the same.

These and other objects are accomplished by providing a construction and ,an arrangement of the various parts in the manner hereinafter described andparticularly pointed out in the appended claims.

Referring to the drawing;

Fig. 2 is a cross sectional view taken on the line 2-2 in Fi 1;

Fig. 3 is a side elevational view showing the manner in which the bag is folded at the center for discharging the dirt from my'improved bag construction;

Fig. 4 is a fragmentary top plan view showing the attachment for supporting the bag at the intermediate portion thereof to the handle;

Fig. 5 is a cross, sectional view taken on the line' 5-5 in Fig. 1; p

Fig. 6 is a modified form of my improved bag construction in which the same is mounted on the conventional form of sweeper preferably onthe 10 top side of the handle thereof; and

Fig. 'l is a cross sectional view taken on the line 1-4 in Fig. 6.

It has been the practice heretofore in connection with the conventional form of suction sweeper or vacuum cleaner of the type in which the dust and dirt collecting bag is attached to the sweeper proper at one end and supported to the handle at the other end, to remove the entire bag from the sweeper and handle in order to empty '20 the contents therefrom. In doing so, it not only entails considerable labor, but also has been heretofore, a disagreeable task to empty the contents from the entire bag after the same has been detached from the cleaner. It is therefore, the primary object of the present invention to eliminate the necessity of removing the bag from the sweeper proper, but to also collect the dust and dirt particles atone end of the bag and detach only one end of the bag from the upper end of the handle and by folding the bag at the center portion thereof, discharge the contents from the pocket formed at the upper end of the bag without removing the bag from the sweeper proper.

In illustrating one form of my invention, I have shown the same in connection with a conventional form of suction cleaner generally indicated by the reference character III, which includes the usual motor operated suction fan mounted within the cleaner. This cleaner is provided with the usual rear supporting rollers II and its forward end as shown at I2, is adapted to rest on the ground or carpet to be cleaned. The rearward portion of the suction cleaner proper is provided with a rearwardly extending tubular extension l3 to which the lower opened end of the conventional dust collecting bag I4 is securely clamped by any conventional clamping means, as shown at 15. Pivotally connected, as

shown at I6, is the usually rearwardly extending 5o handle l'I.

' My improved bag construction for collecting the dust and dirt .in a pocket formed at the upper end thereof includes the usual conventional form of bag, as shown at I4, in which a partition wall ill generally indicated by the reference character I8 is provided. The lower end of the partition wall is substantially the width of the bag and is sewed transversely across the bag at a point substantially the center of the bag, while the outer edges extend upwardly and taper or converge toward the top and are stitched as shown at 20, to the opposite side of the bag from the bottom edge. The top edge of the partition wall, as shown at 2|, is unstitched or opened so that the incoming dust and dirt will follow upwardly toward the top of the bag, in the manner indicated by the arrows in Fig. l of the drawing, so as to deposit the dirt into the pocket 22. In combination with my improved form of bag provided with a pocket for receiving and accumulating the dust and dirt therein, I have provided a novelsupport which engages the center portion of thebag so that the same may be folded at the center in the manner indicated in Fig. 3 of the drawing, after the upper end of the bag has been detached from the upper end of the handle for discharging the dirt accumulated in the pocket. This supporting means for the center of the bag may be in any convenient form, but for the purpose of illustration, I have shown one manner of carrying out my invention, in which I have provided a transversely extending rod 23 extending through clips 24 secured at spaced intervals across the upper side of the bag as shown at Fig. 4. Attached to the center portion of this rod 23, isa chain 25 which may be conveniently attached, as shown at 26, to an intermediate portion of the handle 11. The upper end of the bag is provided with the usual conventional form of bracket 21 of substantially U-shaped cross section for. engaging and closing the upper opened end of the bag for sealing and holding the same in sealed position. This bracket 21 in turn, is connected by means of a spring 28 to the upper portion of the handle I! as shown at 29.

From the above description it will be readily seen that by arranging a pocket in the upper portion of the bag and permitting the bag to be folded at an intermediate-portion thereof or at a point adjacent the lower end of the pocket in the manner indicated in Fig. 3 of the drawing, that the contents of the pocket may be easily emptied from the upper open end of the bag without removing the bag from the cleaner proper. This arrangement not only eliminates the necessity of removing the bag from the cleaner proper, but also prevents accumulation of dirt from clogging the entrance to the bag and permits the cleaner proper to be used a considerably longer, time before the contents of the pocket is removed.

In the modified form of my invention shown in Figs. 6 and 7 in connection with another type of conventional form of vacuum cleaner or sweeper 30, the discharge spout 3| is located on one side thereof and has connected thereto by means of a clamp, as shown at 32, the conventional bag 33. In this instance, the bag is mounted on the top side of the handle 34 and is supported thereon by a spring 35 attached to the usual clamping clip 36 which seals the upper portion of the bag. When my improved form of pocket is used in connection with this type of bag, the partition walls, generally indicated at 31, has its entrance to the pocket, as shown at 38, located on the same side as the spout 3| of the vacuum cleaner 30 is located, so that the lower end of the partition walls 31 is stitched to the opposite side of the bag, as shown at 39, with the upwardly extending sides of the partition wall stitched as shown at 40, towards the mouth 38 of the pocket. In this instance, an attachment similar to that shown at Fig. 4 of the drawing,

is connected at an intermediate portion of the bag adjacent the bottom of the pocket to the top side of the handle 34, so that the upper end of the bag may be detached from its clip 36 and folded forwardly and downwardly to a position similar to the position shown in Fig. 3 of the drawing for discharging the contents of the pocket without the necessity of detaching the entire bag proper from the vacuum cleaner or sweeper.

While in the above specification I have described one embodiment of my invention and a modified form thereof, which my invention may assume in practice, it will, of course, be understood that other modifications may be made without departing from the spirit and scope of the invention as expressed in the following claims.

What I claim is my invention and desire to secure by Letters Patent is:

1. In combination with a suction cleaner, of a dust collecting bag therefor, means located in the upper end of said bag for collecting dirt and dust discharged into said bag, and means for supporting the center portion of said bag for 40 permitting the upper portion of said bag to be folded and for permitting the dirt collected in the upper portion of said bag to be discharged therefrom.

2. In combination with a suction cleaner, of a bag attached thereto, a partition wall located in the upper portion of said bag forming apocket therein, and means for supporting an intermediate portion of said bag whereby said bag may be folded for discharging the accumulated dust and dirt in said pocket from said bag.

3. In combination with a suction cleaner, of a dust collecting bag associated therewith, a handle pivoted to said suction cleaner, means for connecting the upper end of said bag with said handle, means for connecting an intermediate portion of said bag with said handle, and a pocket located in the upper end of said bag for mom mulating the dirt therein, whereby the upper end of said bag may be detached from said handle and suspended from an intermediate portion for discharging the dirt from said pocket.
