v DUST EXTRACTOR AND SEPARATOR.

Application filed February 17, 1908. Serial No. 416,824.

To all whom it may concern:

Be it known that I, IRA. H. SPENCER, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Dust Extractor and Separator, of which the following is a specification.

My invention relates to the class of devices now more especially known in the art as suction cleaners, and the object of the invention is to provide a device of the class named having numerous features of advantage and utility.

, A form ofdevice in the use of which the object sought may be attained is illustrated in the accompanying drawings, in which- Figure 1 is a side view of a machine embodying my invention with parts cut away to show construction. Fig. 2 is'a view in cross-section through the same on the line 2.--2 of Fig. 1. Fig. 3 is a view partially in section through the device on the line 3-3 of Fig. 1. Fig. 4 is a detail view in section on enlarged scale through one of the receiver casings. Fig. 5 is a like view in central section through the upper part of the stack showing the method of suspending the separator.

My invention while not limited to any particular kind of apparatus is especially applicable in that class of suction cleaners in which a rotary fan is employed to create a movement of the air current, and for this reason such an apparatus has been selected by me to illustrate my invention.

In the accompanying drawings the numeral 5 indicates standards supporting a receivencasing 6 constructed of any suitable material, preferably sheet metal, and as shown herein preferably round in cross-section. These casings each contain receivers 7 which may be in the formof drawers each having a handle 8 by means of which it may be removed. These drawers are'co-nstructed to receive material at the top, as shown in Fig. at of the drawings. The standards and casings are of suflicientstrength to support the entire apparatus including a motor 9 of any approved form of construction.

In some'instances it maybe desirable to support the motor 9 in a different manner than as herein shown, and in order to adapt the apparatus to accomplish this result,.and at the same time not employ more parts than i are actually required, the parts herein shown as adapted to support the motor with its shaft in line with the shaft of the fans comprising the blower are made removable. To this end the upper part of the standards 5 are each formed on opposite sides of the easlngs 6 W1th bridge seats 10 on which the bridges 11 rest and to which they are secured as by means of bolts or any other suit-able form of attachment. These bridges are preferably in the form of arches fitting the caslngs 6 and on the top of the bridges socket pleces 12 are located. Although not essential, in the preferred form of construction these bridges are made of cast metal and the socket pieces 12 are integral therewith. Sockets 13 are formed in each of the socket pieces in which sockets are located bars 14; extending between the bridges appurtenantto each of the standards 5 and projecting at one end of the structure to a distance suf- "ficient to receive the motor 9. Clamp screws 15 may be employed to hold the bars in position. A motor support 16 is formed at each end with lengthwise openings through which the bars 14 extend. These openings are somewhat wider than the bars 14 so that the latter may have a movement therein. Ad justing screws 17 and 18 extend respectively through the bottom and top of the motor support as a means of locating the base with respect to the bars and thus provide a vertical adjustment of the support for the purpose of alining its motor shaft with the shaft of the blower. Lateral adjustment may be obtained as by means of bolts extending from the motor support through slots in the motor base, suit-able nuts being employed for holding the parts together. It will be seen from this construction that the casings containing the receivers may be of comparatively light construction as the weight of the motor will be received by the bridges and transmitted to the standards 5, thereby relieving the casings from any part whatever of the weight of such motor.

The numeral 19 denotes a blower casing, and by the term blower as used herein is meant a device for creating flow of a current of air, whether the working effects of this be utilized from the intake or from the exhaustend of said blower. In the arrangement of the apparatus herein illustrated the efi'ective work of the air current is obtained at the intake end of the blower.

Patented Nov. 5, 11912 able length for any special requirement, and

wings 24 located at suitable intervals apart project from the partition 22.

An intake 26 to be hereinafter referred to is connected with one of the receiver casings, in the form of structure herein shownthat casing located at the end of the shell next to the blower.

Cleaning devices, referably in the form of tools constructed or application to floors,-

walls, carpets, and the like, are connected with the intake 26 by any suitable means, the fan or blower serving to create a flow of air inward through said intake and thus produce a suction at the mouth of the cleaning tools by means of which dust is conveyed from the floors or fabrics by the current of air passed through the blower.

A plate 27 is located at one end of the shell 19, and on the fan side of said plate a deflector 28 is arranged. This deflector, as shown in Fig. 2, extends from the outer edge of the plate in a curved direction approaching gradually nearer its axial center the farther it extends. The shaft 20 is supported by this plate projecting through it, the opening in which the shaft is located, however, being protected from the entrance of dust so that the plate is practically closed at this point. In fact, in effect it entirely closes this end of the shell except for an opening 29 extending through the plate preferably at the end of the deflector 28. The deflector is provided at its end with a hood 30 so constructed that a current of air, and the dust or dirt commingled therewith passes within this hood and is thereby guided into the opening 29. A connecting tube 31 leads from the opening 29 into a chamber 32 in a stack 33. The chamber 32 is located at the lower portion of the stack, its location preferably, and as herein shown, being below the line of the axis of the shaft 20, and in the preferred form of construction the opening 29 through the plate is on'the horizontal level of the axis of the shaft. The chamber 32 is separated from the upper part of the stack by a wall 34, which wall, however, is of inverted conical shape having a floor or shoulder 35 and a throat 36.

A separator 37 constructed preferably of fabric of comparatively thin mesh is supported within the upper part of the stack 33 and hasat its lower end a weight 38 of ring shape resting upon the floor or shoulder 35 to hold the screen or separator in proper position. An outlet 39 is located atthe top of the stack 33, to which a pipe may be connected through which the air may be delivered to any suitable point.

.The device as herein illustrated and described is particularly compact and the arrangement of the mechanisms for delivering the air from the shell into the stack is such that the latter is not of objectionable length, extending only a short distance above the shell, and at the same time the construction is such that the impurities contained within the air will be separated therefrom to a great extent before the air passes through the screen or separator 37.

In the machine herein illustrated and described and embodying my invention in one form, it will be seen that the action of the fan produces inflow of a current of air at the mouth of the cleaning tools, through the tubing and intake 26, from which it turns upward over the receiver 7 at the left-hand end of the machine, this deviation of the air current causing the heavier portions of dirt and dust with which the air current is laden to be deposited in said reservoir. The current passes through 'the shell under the influence of the fan into the chamber 40. where, by the action of the fan in that chamber it is given a circular motion. The current coming in contact with the deflector 28 is directed inward toward the axial center of the shell, encountering the hood 30, which causes it to flow through the connecting tube 31, which tube is arranged tangentially to the wall of the circular chamber 32, Where it again takes up a circular motion. The threat 36, however, being located below the tube 31, causes the circularly moving current to travel downward and then make an abrupt turn upward through the throat 3.6 and within the screen or separator 37. The.

circular movement of the current of air within the chamber 32 causes the heavier portions of dirt or dust to be thrown off by centrifugal force, and the action of gravity causes such portions to drop andbe deposited in the reservoir 7 at the right-hand end of the machine. The air current, by the action of the mechanism, is relieved to a very great extent, if not wholly of foreign matter as dust or dirt, and what little remains is removed by the screen 37, so that practically a current of free air passes out through the outlet 39. The deviation of the air current from the chamber 40 to the lower levels of the machine and within the chamber 32 enables the screen 37 to be set low, and thereby an extremely short stack may be employed, providing a very compact apparatus.
