To all whom it may concern:
Be it known that 1, WILLIAM W. Bosnia- FIELD, a citizen of the United States, residing at White Plains, in the county of VVestchester and State of New York, have invented certain new and useful Improvements in Suction Cleaning-Nozzles, fully described and represented in the following specification and the accompanying drawings, forming a part of thesame. i
This invention relates to suction cleaning nozzles. In order that a suction cleaning nozzle shall be eflicient in taking up from a carpet or other surface being cleaned thread, lint, hair or other loose fibrous material, or other articles or particles of matter which tend to adhere to the surface being cleaned, it is desirable that the nozzle shall be formed or provided with means to cause a current 20 of air to pass over and against the surface and into the nozzle. It is also desirable for best results that the nozzle be provided with a suitable disturbing device to engage and loosen the threads or other material from the surface being cleaned, such disturbing device being most desirably located within the nozzle opening. For the more thorough cleaning of a carpet or other floor covering or other fabric of other kinds of dust or dirt, an extraction of its 7 contained dust, however, it is desirable that the nozzle shall operate without causing such surface cleaning current of air, but so as to cause substantially all of the sucked-in air to pass through the body of the fabric; and to accomplish this result it should be possible for the carpet or other fabric which is drawn against the lips of the. nozzle or against which the nozzle is pressed to become practically sealed against the thereby substantially prevent the passage of air over'the surface of .the carpet into the nozzle. 4 The object of the present invention is to provide a suction cleaning nozzle which shall be adapted to operate efliciently botnin picking up threads and other material from the surface to be cleaned and for cleaning by the suction of air through and extraction of 50 fabric to be cleaned. The desired inward draft over the surface being cleaned may be secured in a very satisfactory manner by forming one or both lips of the nozzle with Specification of Letters Patent.

"suitably proportioned notches, or recesses, so
that when the notched nozzle lip is in engagement with the carpet or other surface being cleaned the notches will provide open passages for the free flow of air into the nozzle over and against the surface of the carpet. Such a notched nozzle lip seriously lnterferes, however, with the cleaning action by suction through the carpet or other fabric being cleaned. In order to avoid this objection and to accomplish the object of the invention, that is, to make the nozzle equally adapted for cleaning by suction through a fabric or for cleaning by a draft over the surface, I form the nozzle so that it may be readily 'convertedfrom one hav- 1ng a notched or surface draft lip to one having a continuous or sealing lip for through suction cleaning. I also most desirably provide the nozzle with a brush or other suitable disturbing member mounted so as to be movable into and out of operative position, and most desirably this brush is connected with the means for converting the nozzle lip so that the brush will be in operatlve position when a surface draft is being secured and will be moved out of operative position when the nozzle is adjusted for through suction cleaning.
A full understanding of the invention-can best be given by a detailed description of an improved embodiment of the same, and such a description will now be given in connection with the accompanying drawings, which illustrate theinvention as applied to a self-contained suction cleaner. In said drawings:
Figure 1 is a view in side-elevation of a self-contained cleaner provided with a suction cleaning nozzle embodying the various features of the invention.
Fig. 2 is a transverse sectional view of floors, walls, furniture, etc., also that it may be applied to nozzles of self-contained cleaners of other kinds than that shown.
Referring to the drawings, Fig. 1 shows a suction cleaner which is more fully shown and described in my application for U. S.
The nozzle is extended transversely in the usual manner to provide a comparatively long and narrow suction inlet opening or mouth between the lips of the nozzle. The body is mounted on a pair of running wheels located adjacent and to the rear of the nozzle and a small rear wheel, and the cleaner is operated by a pivoted handle rod 16 and is provided with a porous dirt receptacle or bag 17 connected at its lower end to the discharge throat or conduit 18 extending backward from the fan casing, the upper end of the bag (which is not shown) being supported by a suitable connection to the upper end of the handle rod. The running wheels are shown as positioned to support the nozzle slightly above the normal plane of the surface to be cleaned; but it will be understood that a nozzle embodying the present invention is not necessarily so used.
One of the nozzle lips is formed toprovide for the passage of air into the nozzle past and against the surface being cleaned, and for this purpose, in the construction shown, the front lip or bottom of the front wall of the nozzle is formed with a series of notches or recesses 20. It is desirable to form the nozzle lip with such a series of notches or recesses instead of cutting away the lip throughout its whole or a considerable part of its length, in order that the portions of the lip extending between the notches may serve to prevent the fabric being cleaned from being drawn by the suction against the nozzle in such a way as to seal the desired inlet passage for the surface cleaning current. The shape, size and proportionate dimensions of the notches or recesses may, of course, be widely varied. Mounted within the nozzle is a shutter formed by a bar'21 carried by arms 22 pivotally connected to the end walls of the nozzle, so that whenthe bar is moved down into operative position, as shown in Fig. 3, it will close the air inlet passages provided by the notches 20 and will provide a continuous edge for the nozzle lip to bear against the fabric being cleaned so as to substantially prevent the passage of air inward over the surface of the fabric. By swinging the bar up to the inoperative position shown in Fi 2, the
air inlet passages through the note es are left free for the flow of the surface cleaning current of air through them.
A disturbing device or member 23 is also mounted within the nozzle so as to be movable into and out of operative position, and, as shown, this disturbing device is carried by the pivoted arms 22 on the opposite side of the line of the pivots from the shutter bar 21, so that when the shutter bar is in operative position to close the notches 20, as shown in Fig. 3, the disturbing device will be lifted to an inoperative position, and when the shutter bar is raised to its inoperative position above the notches the disturbing device will be moved down into operative position, as shown in Fig. 2. The disturbing device should be of asuitable character to frictionally engage and exert the necessary pull or drag on the threads, etc, with which itcomes into contact, and might for this purpose be made of any suitable material, but is most desirably formed by a row of tufts of suitable bristles forming a long narrow brush, as shown in the drawings.
The shutter bar and disturbing brush may be shifted or adjusted to the desired positions by any suitable means. But most desirably I provide for this purpose a setting rod 24 which passes upward through an opening in the nozzle wall and which carries at its upper end a head 25 and is connected at its lower end, as through the medium of a link 26, with the shutter bar 21, so that when the rod is pushed downward, as by the user of the machine pressing on the head 25 with his foot, the shutter bar and disturbing brush will be moved to the positions shown in Fig. 3, and when the rod is lifted the bar and brush will be shifted to the positions shown in Fig. 2. In order to hold the bar and brush in either of the positions to which they have been shifted, any suitable holding means may be pro- Vided, as, for example, a spring catch 27 as shown, which is adapted to engage in notches formed in the rod 24.
It will be understood that the invention is not to be limited to the exact construction, arrangement and combination of parts as shown in the drawings and to which the foregoing description has been largely confined, but that it includes changes and modifications thereof within the claims.
What is claimed is:
1. The combination with a suction'cleaning nozzle having a lip formed to provide a passage for the flow of a surface cleaning current of air between the nozzle lip and the surface to be cleaned, of means movable into and out of operative position formed to close said passage when in operative position, the lips of said nozzle and said means with the surface to be cleaned when said insane-r means is in operative position, and a thread disturbing member movable into and out of operative position within the nozzle.
2. The combination witha suction cleaning nozzle having a lip formed to provide a passage for the flow of a surface cleaning current vof air between the nozzle lip and the surface to be cleaned, of means movable into and out of operative position formed to close said passage when in operative position, a thread disturbing member movable into and out of operative position, and means controlling the position of said movable pants to cause one of said movable parts to be out of operative position when the other is in operative position. I
3. The combination with a suction'cleaning nozzle having a lip formed to provide a passage for the flow of a surface cleaning current of air between'the nozzle lip and the surface to be cleaned, of means mounted within the nozzle movable into and out of operative position formed to close said passage when in operative position, a thread disturbing member mounted within the nozzle and movable into and out of operative position, means for controlling the position of said movable parts comprising an operating member extending outside the nozzle casing whereby when one of said movable parts is moved into operative position the other is moved out of operative position, and
means for holding said parts in the positions to which they are moved by the operating member.
a. The combination with a suction cleaning nozzle having a lip formed to provide a passage for the flow of a surface cleaning current of air betweenthe nozzle lip and the surface to be cleaned, of means mounted within the nozzle and movable into and out of operative position formed to close said passage when in operative position, a thread disturbing member mounted in the nozzle and connected with said means to move into operative position when said means is moved into inoperative position, and an operating device for said movable parts extending outside the nozzle casing.
5. The combination with a suction cleaning nozzle having a lip formed with notches to provide inlet passages for surfacecleaning currents of air, of a shutter mounted within the nozzle to move about an axis extendinglongitudinally of said lip and mov- .able into and out of an operative position in which it stands against the inner face of the nozzle wall and closes said inlet passages.
6. The combination with a suction cleaning nozzle having a lip formed with notches to provide inlet passages for surface cleaning currents of air, of a shutter movable into and out of operative position formed to close said passages when in operative position, the lips of said nozzle and said shutter being arranged to make continuous contact with the surface to be cleaned when said shutter is in operative position, and a thread disturbing member movable into and out of operative position within the nozzle.
7. The combination with a suction cleaning nozzle having a lip formed with notches to provide inlet passages for surface cleaning currents of air, of a shutter movable into and out of operative position formed to close said passages when in operative position, a thread disturbing member movable into and out of operative position, and means for causing said thread-disturbing member to move with the shutter but oppositely thereto, so that when the shutter is moved into operative position the disturbing member will be moved out of operative position and when the shutter is moved out of operative position the disturbing member will be moved into operative position.
8. The combination with a suction. cleaning nozzle having a lip formed with notches to provide inlet passages for surface cleaning currents of air, of a shutter bar and a thread disturbing member carried by arms pivotally mounted within the nozzle to swing about an axis extending between the shutter bar and the disturbing member so that when the brush is in operative position the shutter bar will be raised to inoperative position and when the brush is raised to inoperative position the shutter bar will be in position to close said inlet passages and to act as a continuous nozzle lip, and means for holding said movable parts in position with the disturbing member in operative position or with the shutter bar in operative position as desired.
