vncnux-cmmnn.

To all whom at may concern:

Be it known that I, CHARLES A. DELON,

a citizen of the United States, residing at Canton, in the county of Stark and Stateof Ohio, have invented certain new and useful Improvements in Vacuum-Cleaners, of which the followin is a specification.

The invention rel including an electric motor, a suction tan and a separating chamber communicatin with a plurality of inlet openings adapted to communicate With the tubular shanks of.

suction nozzles. Such machines are designed and sold for the use of one or two or some other particular number of suction nozzles at the same time, and it desirable for practical reasons to construct the fan with a greater capacity than necessary to. create the proper suction in the shanks oi the particular number of nozzles which may be used; and it is also desirable for economy to make the motor'with only a little greater capacity thannecessary to create such sum tion. in, the operation of these machines dificulty has been experienced when more than the particular number of inlet openings have been purposely or accidentally used:

or opened at the same time, growing out of the fact that the work of the fan and the load on the motor will be so increased as to burn out the motor. This difliculty is over-' come by roviding a partition betweenthe', fan cham er and the inlet openings with an, orlfice therein of. substantially the same a cross area as. the combined cross areas of v the openings in the particular number of suction nozzles which -ma limiting the amount of a11- which can be drawn into the fan to the amount of-air Wl'llCh may properly-be drawn through the shanks of such particular nozzles.

The invention thusdescribed, as embed-i .ied 111 a stationary vacuum cleaner, is illustrated in the accompanying drawings, forming' part hereof, inwhich- Figure 1 is a side. elevation of the vacuum cleaning machine, with some parts broken away to show interior details; and :Fig. 2,

REISSUED an elevation section of the electric motor, the fan blower and the upper partof the separating chamber.

Similar numerals refer to sim lar parts throughout the drawings.

The machine includes the chamber .1 within the cylindric case 2, the fan chamber 3 within the blower case 4:, and the fan 5 located in the fan chamber and secured on the lower end of the spindle 6 of the electric motor 7 which is secured on the blower case.

separating The inlet opening 8 of the collectingchamber is provided in the cylindric case 2,

and communicates with the main conduit 9 which is preferably extended inward or adjacent to the Wall of a building (not shown), and is provided with a plurality of inlet openings 19 normally closed by the valves 11, for use in cleaning the various apartmcnts of the building. One or more suction nozzle communicates with the collecting chamber through said conduit.

The cross area as at.:v-w of the opening in. the shank of each nozzleis suitably proportioned to the area of the opening of the inlet slot 12 of the nozzle to properly pernozzles, as 12, are provided, and the tubular form the work thereof, and substantially-the same size of opening prevails throughout the nozzle-shank, the tubular extensions thereof, and the communicating inlet opening. The cross area as at 3 of the main conduit is preferably made much larger than the combined cross areas of the openings in the particular number of nozzle shanks designed to be operated at one time, which enlargement is made forthe urpose of de creas theresistance and i i-iction caused by the ow of air through the main conduit,

the same being generally extended a 'con- F siderable distance from the machine to the various inlet openings. For the purpose of reducing frictional resistance inthe fan' 5 at the speed adopted for operating the machine, the same is likewise made consider- 7 ably larger in capacity, that is, the peripheral outlet slot 16 is widened to make a considerably larger outlet area than the combined areas of the openingsin the shanks of the particular number of nozzles to be used at the same time; and thisslot is so widened for the further purpose of freely passing articles of refuse which may be drawn 1 through the fan and which would otherwise vacuumor suction in the tubular shanks of the particular number of nozzles which may a, be properl used.

The or' ce 17 which constitutes the inlet to the fan chamber is provided in the part1t1on separating this chamber from the collecting-chamber, and, for the purpose of this invention, the cross area, as at zz, of this orifice, is made substantially equal to the combined cross areas of the openings of the particular number of nozzles designed to be used at one time; so that the 'fan can only take in the amount of air which prop.- erly passes through the shanks of such articular number of nozzles, and, there ore, the capacity'ofzthe motor cannot be overloaded to injure or to'burn it out.

I claim: 1. A vacuum cleaner including a separatng chamber having a plurality of valved inlet-openings communicating therewith, suction nozzles having tubular shanks adapted to be connected with the inlet-openings, a suction fan having a capacity greater than that requ red for the combined cross-areas of a partlcular numberof nozzle-shanks, a motor connected with the fan having a capaclty substantially equal to the require ments of sald particular number of 'nozzlerating-chamber and the fan having an orifice thereln with a cross-area substantially equal to the combined cross-areas of said particular number of nozzle-shanks.
