HASTINGS, MICHIGAN, A CORPORATION OF MICHIGAN.

VACUUM-CLEANER.

Specification of Letters Patent.

To aZZ'whom it may concern:

Be it known that I, EDWARD M. BARNEs, a citizen of the United States, residing at Hastings, county of Barry, and State of Michigan, have invented certain new and useful Improvements in Vacuum-Cleaners, of which the following is a specification.

This invention relates to improvements in suction cleaners.

The main objects of this invention are,

casing formed mainly of sheet metal, which is very light and compact. Third, to provide in a suction cleaner, an improved casing in which the parts are sheet metal stampings and are simple in form and easily produced and assembled. Fourth, to provide in a suction cleaner an improved casing by which the motor is efl'ectively incased and supported. Fifth, to provide in a suction cleaner an improved casing structure which can be readily disassembled if occasion requires to afford access to the motor or the fan and easily reassembled. Sixth, to provide an improved suction cleaner which is adapted for use as a sweeper,that is, one which is moved bodily across the rug or other article to be cleaned, or is readily adapted for use with attachments.

Further objects relating to structuraldetails, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and. pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this invention, in which: I

showing the delivery nipple of the 'fan chamber. Fig. VII is a detail section taken on a plane corresponding to line 77 of Fig. I, showing details of the joint for the sections of the fan chamber. Fig. VIII is a detail section showing suction tube attach- Fig. IX is a detail vertical section showing a brush attachment. Fig. X is a bottom view of my improved suction cleaner arranged for the use of attachments? In the drawlngs, slmllar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking inthe direction of the little arrows at the ends of the section lines.

Referring to the drawing, the base or shoe shallow pan. Mounted on the base orshoe A is a fan casing formed of a pair of pan-like sections 4 and 5. The bottom section 9} is secured to the shoe 1, while the topsection 5 is mounted on the section I. To secure a good joint betweenthe sections and rigidly support the parts, the top seotioff 5 is offset or shouldered at 6 to receive the edge of the section 4, and the section 4is provided with lugs 7,"which are struck up therefrom, as shown in Figs. I and VII, while the section 5 is provided with coacting seats 8, the seats being struck out from the offset portions, 6. As the sections are forced together, the lugs 7 snap into their seats 8. If desired, in order to insure an air tight joint between the sections 4 and 5, some sealing material may be usedin the joint, as will be readily understood. To afford an effective means of attaching the handle 9, and to reinforce the parts and connect the shoe 1 with the fan casing, I interpose a plate 10 between the v The fan 15, which .'s shown mainly inconventional form, as its structural details form do part of my present invention, is mounted on the lower end of the verticallydisposed shaft 16 of the motor. The bearing 17 for the lower end of the shaft 16 is mounted on the top section- 5 ofthe fancasing, the section 5 being provided with a central opening having supporting flanges 18 for the bearing. I

-The motor casing consists of a base section 19 mounted upon the fan casingsection 5, and the top section 20 mounted upon the section 19. Both of these motor sections or

members

19 and 20 are sheet metal stampings. The motor casing section 19 is provided at its lower end with an out-turned flange 21, which rests upon and is secured to the top section 5 of the fan casing by means of the bolts 22." At its upper end,

the section 19 is shouldered at 23 to receive the top section 20 and is provided with an inturned top flange 24. J This flange 24 is provided with cars 25, on which the fields of the motor are mounted, and with upwardlyprojecting arms or brackets 26 in which the brush holders'are mounted. See Figs. III

andIV. The fields 27 are arranged under casing section 20, which is provided with bearing supporting flanges 30. The brushes 31 coact with the commutator 32 on the [armature shaft. The tubular brush holders 35 are provided with tubular insulating sleeves 33 arranged through suitable flanged openings 34 in the arms 26. The brushes 31 are slidinglymounted and yieldingly supported in the holders 35 by the springs 36, the inner ends of the springs engaging the brushes while the outer ends of the springs engage the plugs 37 threaded into the holders. The top motor casing section 20 is provided with openings 38 through which the brushes may be inserted or removed. The top section 20 also has ventilating openings 39 in its top. With the parts thus formed and arranged, the parts of the motor are incased and protected and effectively' supported so that they are kept in alinement and no additional brackets or supporting parts are required, other than the bearings described and the parts formed on the casing.

The plate 10 is provided with a hinge member extension 40 at one side to which the hinge-member 41 of the handle is connected by means-of the pintle 42. The handle 9 is tubular; being formed of longitudi-' nal sections 43, which are glued together, and further retained by the ferrule 44 at the outer end ofthe handle and the ferrule ing screws 47 45 at the inner-end, the ferrule 45 being formed integrally with the handle hinge member 41. The ferrule 45 is split and provided with pairs of ears 46, and with clamp- The circuit cord 48 is arranged through the hollow handle, as shown, and connected by a coupling 49 to the motor wires 50.

The fan casing sections 4 and 5 are provided with

integral nipple extensions

51 and 52, respectively, which are joined together in the manner, described. A ferrule or sleeve 53 isslipped over these nipple sections, the ferrule being provided with channels 54 on its sides adapted to receive the seams formed by the joint of the sections. This ferrule serves as a lock for the fan casing sections. The sleeve or ferrule 53 is provided with a flange 55 at its outer end over which the mouth of thedust bag 56 is arranged. The bag 56 is suspended from the handle. A supporting chain 571: provided for vthe handle, one end of the chain being connected to the motor casing.

The shoe plate 58 is provided with opposed segmental portions 59 having upturned flanges 60 at their edges adapted to fit into the flange of the shoe 1, as shown in Figs. II and III. The front and rear edges of the shoe plate are spaced from the flange of the shoe 1, leaving segmental openings 61 at the front and rear thereof for the entrance of the dust. The shoe plate is provided with upturned flanges 62 at its front and rear edges. -The shoe is preferably provided with arm-like extensions 63 having channels 64 therein opening into the base. These extensions are radially disposed on the front side of the casing, the distance between their ends being about the diameter of the base. In using the machine, these extensions may be run into corners or other'places whlch could not otherwise be cleaned without the use of attachments. When desired, the shoe plate 58 may be removed and a brush 65 inserted in lieu thereof, or when it is desired to use an attachment, the base plate 58 is removed and the attachment plate 66 substituted therefor, the plate having a nipple 67 for an attachment tube 68. The plate 66 entirely closes the shoe or suction chamber.

When the device is intended for use with an attachment, it is laid on its .front side, the arms 63 forming supports. See Fig. X. By forming the parts of the casing as I have illustrated and described, they may all be produced by drawn or die work, and each so formed that the structure is very'compact and light in weight. Each section or member of the casing is,,owing to its shape,

reinforced so that, while light material 1s used, the casing is very strong and rigid.

For instance, the motor casing section 19 is reinforced by't-he flange 21 at its base, the

shoulder 23 and the flange 24 at the top. The casing section 20, owing to its cup form, and being pressed upon the section 19, is also made very rigid. The pan-like shape of the shoe 1 and the fan casing or sections t and 5 and their joints render these parts very rigid. The plate 10, to which the handle is connected, reinforces these parts and provides a connection for the handle thereto which minimizes the strain thereon. Lightness in weight, as will bereadlly I appreciated, is of great advantage in the use of the apparatus, as well as in reducing the cost of materials. The parts are easily assembled, and areso constructed thattheymay be assembled by unskilled workmen, which eifects another saving in'the cost of manufacture, and this, of course, is of very great advantagev in the case of its being necessary-to disassemble, the device for purposes of repair.

The bearings of the motor may be effectively lubricated, the upper bearing directly, and the lower bearing through the oil conduit 69.

I have illustrated and described my improved suction cleaner in the form in which I have embodiedit. I am aware that considerable variations in structural details are possible," but as such variations will no doubt be readily understood by those skilled in the artto which this invention relates I have not attempted to illustrate or describe the same herein. I desire to be understood as claiming the same specifically in the form illustrated, as well as broadly within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a suction cleaner, the combination of a shoe comprising a circular plate having downwardly projecting flange at its. edgeand channeled arms, said arms being extensions of said flange, said flange and arms being provided with arim-like tread; and a removable shoe plate having upturned flanges at its side edges telescoping with the flanges of said shoe, there being-a space between the front and rear edges of said plate and said flanges;
