UNITED STATES- ABRAHAM N. SPANEL, OI BOCKESTEB, NEW YORK.

VACUUM Application filed February As is Well known to those skilled in the art, there are today two general types of household vacuum cleaners. One of these types has a narrow nozzle withouta revolv ing brush and depends for its cleanlng actlon upon the high suction produced 1n the nozzle. The other type of cleaner is one 1n which a broad nozzle is employed and in which a revolving brush is located.

The principal object of my invention has been to provide a vacuum cleaner having both types of nozzles, thus obtaining all the advantages of both types of cleaners, as well as other advantages hereinafter pointed out.

Another object has been to provide a double nozzled vacuum cleaner having means such that either of the nozzles may be used alone.

Furthermore, my device is preferably provided with means whereby, when the brush nozzle is to be shut off, the belt which drives the brush shall be lifted from the drive shaft, and simultaneously lowered onto the drive shaft when the nozzle is a ain opened for use.

The above objects an advantages have been accomplished by the device shown'in the accompanying drawings, of which:

Fig. 1 is a side, sectional elevation of one form of my device, showing the brush nozzle in operation.

Fig. 2 is a perspective view of the nozzle shutter of the form of device shown in Fig. 1. Fig. 3 is a plan view of the device shown in Figfil.

Fig. 7 is a fragmentary, sectional view of another form of invention.

Fig. 8 is a perspective view of the shutter used in the form of invention shown in Fig. 7.

Referring to the form of invention shown in Figs. 1, 2, and 3, my device comprises a motor 10, which is secured by any suitable means to the fan casing 11. The fan casing provides the fan chamber 12, in which is mounted a fan 13. The fan is carried by the motor shaft 14. The fan chamber is provided with an inlet opening 15 and with an outlet nozzle 17. The dust collecting bag 18 is attached to the nozzle 17 in any well known manner.

CLEANER.

5', 1826. Serial No. 88.808.

The body 20 of my device is provided with a suction chamber 21, immediately in front of the Inlet opening 15 of the fan chamber. Arranged at the forward end of this suction chamberis the shutter 22 of my device. This shutter 1s preferably provided with a ring portion 23 which is rotatably mounted in the bod 20 of the device. Substantially onehal of the face portion of the shutter is cut away so as to form an opening 24. The other half of the face portion is provided with a solid wall 25. ,A slot 26 is formed in the body portion 20 for the passage of an operating nob 27, carried by the ring portion 23 of the shutter. A brush operating shaft 28 is attached to the motor shaft 14 and extends through an aperture 29, formed in the shutter. The forward end 30 of the shaft extends beyond the shutter and is designed so as to receive a belt 31. Carried by the-shutter 22 is a belt shifter 32, which extends forwardly and is arranged adjacent the forward end 30 of the brush operating shaft. Arranged at the forward end of the cleaner is a unitary floor nozzle structure comprising a main nozzle 35 and an auxiliary nozzle 36. The nozzle structure is secured to the fan casing by any suitable means, so that the structure may be easily and quickly assembled or disassembled. These nozzles are adjacent to each other and are separated by a dividing wall 37 The other side of the main nozzle 35 is bounded by a wall 38 and the rear side of the auxiliary nozzle 36 is bounded by a wall 39. The wall 38 is provided near its upper end with an opening 40 for attachments. This openin is closed by a plate 41. The dividing wall 37 extends upwardly and rearwardly to a point above the brush operating shaft 28, and preferably contacts with the shutter 22. Arranged in the auxiliary nozzle 36 is a revolving brush 45 havin a shaft 46, provided with a pulley 47. The belt 31 passes over the pulley 47, whereby the brush is driven.

Supporting wheels 48 are arranged near the forward end of the device, and adjustable supporting wheels 49 are arranged near the rear of the device. An adjusting screw 50 serves to raise or lower the rear end of the cleaner, thus governing the distance between the lower edge of the nozzles and the floor covering being cleaned.

In the form of invention shown in Fi 4, the shutter 55 is similar to the shutter o the form of invention shown in Fig. 1, and it is p v d d w th a ri g portion 56 and an open ing 57 in substantially one-half of its face surface. A wall 58 closes the other half of its face surface. A slot 54 is formed in the housing for the reception of the operating handle 53 of the shutter 55. In this form of invention, the shutter is arranged adjacent the inlet opening 59 of the fan chamber 60. The fan 61,- which is mounted in the fan chamber 60, is secured to the shaft 62 of the motor 63. A main nozzle 64 and an auxiliary nozzle 65 are provided, separated by a dividing wall 66. In this form of the device the main nozzle is shown in action, the shut- .ter being so adjusted as to open this nozzle into communication with the fan chamber. Adjustably mounted supporti wheels 69 are arranged at the forward en of this device, whereby the lower edge 67 of the nozzles may be adjusted with respect to the floor covering. As shown in Fig. 4, the brush is out of contact with the floor covering, since the floor covering is drawn only into contact with the main nozzle when this nozzle is being used. A su porting wheel 68 is provided at the rear of t e device.

In Fig. 5 I show a form of device in which the inlet opening in the fan chamberis not restricted by the shutter. In this form of invention the fan chamber is represented M70 and the inlet opening thereof at 71. A fragmentary portion of the fan is shown at 72, which 18 mounted upon the motor shaft 73. The shutter 74 of this device is in the form of an open cylinder as clearly shown in Fi 6, and serves to cut of! either the main nozz e .75 or the auxiliary nozzle 76, both shown in fragmentary manner. The forward end of the cylinder is cut away at 77 back from the forward edge a distance sufiicient to expose the main nozzle 75. The cut-away portion extends preferably to a point near the horizontal center line of the cylinder. At a point diametrically opposite the cut-away portion 77 and at the opposite end of the cylinder, there is provided a cut-away portion 78, which is of a width substantially the same as the width of the upper end of the auxiliary nozzle 76. This cut-away portion also extends to a point near the horizontal center line of the cylinder. At operating handle 79 is provided on the cylinder 'which passes through a slot 80, whereby either the nozzle or the nozzle 76 may be connected with the inlet 71 of the fan chamber 70.

In the form of device shown in Figs. 7 and 8, a shutter 81 is arranged immediately in front of the opening 82 of the fan chamber 83. This shutter is provided with a ring or cylindrical portion 84. A portion of the ring or cylinder is cut away at 85 a distance back from the edge of the cylinder sufficient to expose the upper. end of the auxiliary nozzle 86, when it is in position to connect the auxiliary nozzle with the fan chamber. The opposite end of the cylinder is provided with an opening 87 in its front face portion which registers with an opening 88 ormed in the upper end of the main nozzle 89 and which serves to connect t e main nozzle 89 with the fan chamber 83 w en the shutter is in the position shown in Fig. 7. This end of the shutter is also provided with a wall 90 which serves to close the opening 88 when the shutter is in the position opposite to that shown in Fig. 7. When in this position the opening 87 in the shutter is closed by the portion of the wall 91 of the main nozzle 89.-

When operating the form of invention in Figs. 1 to 3, it will be obvious that with the shutter in the position shown in 1, the main nozzle 35 will be shut off and air will be drawn up through the brush nozzle 36. When in this position the belt shifter 32 will be below the shaft 28. When, however the shutter is operated to close off the auxiliary nozzle 36 and bring the main nozzle 35 in use, the belt shifter 32 will engage the belt 31 and hold it out of contact with the forward end 30 of the operating shaft. It will be obvious that when the brush shifter is in this position, the wall 25 will close ofi the upper end of the auxiliary nozzle 36. Clearly in the other forms of invention, the shutters may be operated so as to open or close either of the nozzles desired. If desired both nozzles may be used at the same time by moving the shutter of either form into an intermediate position.

Obviously, some modifications of the details herein shown and described may be made without departing from the spirit of my invention or'the scope of the appended claims, and I do not, therefore, wish to be limited to the exact forms herein shown and described, the forms shown being merely preferred embodiments thereof.
