CARPET-SWEEPER.

Specification of Letters Patent.

v Patented Feb. 4, 1908.

Application filed January 31| 1907. Serial No. 355.047.

vTo' all whom fit may concern.'

Be it known that l, THoMAs L. T OTTEN, a citizen ofthe United States, residing at Brooklyn, in the county of Kings and State the following is a s ecification.

This lnventlon re ates to a carpet sweeper which can be made practically dust proof; and which also possesses other features and i the invention resides in the features of construction set forth in the following specification and claim and illustrated in the annexed drawlng, in which:

Figure 1 1s a front elevatlon of a carpet sweeper embodying this invention. Fig. 2 is a section along the line w w Fig. 1.' Fig. 3 is a section along the line :c :l: Fig. 2. Fig. 4 is a front view of the handle of Fig. 1 partly in section. Fig. 5 is a section along line z z Fig. 4. lig. 6 1s an end elevation of the sweeper. Fig. 7 is a section along y y Fig. 1.

In this drawing is shown a casing a with bottom sections b hlnged thereto at c c. The caslng has fixed fulcrum polnts e to each tof which is fulcrumed a lever d, to each of which levers a bottom section is linked as seen atf. The levers are of the first class order and connected at their inner ends to a stem g having a handle or finger button h by which the stern g can be rotated and moved lengthwise. The stem g has a rotative connection with the levers, and is provided with a pin or projection i which passes beneath a shoulder c on the end of the casing when the stem is depressed and rotated.

If the handle or stem is pushed in and its locking stud or projection i turned to engage shoulder or lock part c the bottom sections b by means of 'links f and levers d fulcrumed at e will be raised to closing position. f the stem g is turned or released from shoulder k and its stud i, moved along or throu h releasing part shown at the shoulder the evers d are swun to dump or open the bottom so that the co lected dust wi discharge.

As the bottom sections are hinged at their outer edges they open so as to incline inward or toward the center art of the casing and the contents or sweepings will not be thrown outward but converged toward a central point or line to be kept to ether. .Scattering being avoided the devlce aids 1n maintaining cleanliness.

At two fixed points at each side of the casing indicated at m arepivoted links 'n which ,f at their inner ends are separately ivoted at l i 0 to the ends or engaging parts o a bail p. This link connection has sufficient play or looseness at its pivot points m o so that it allows the handle or stlck q to be brought to any convenient tilt for directing the device over the floor or car et.

The bail p has a sultable prong or fork portion and the stick g is-grooved and on a ring r. 'hen the stick has been passed into lace on the bail or fork the ring r is rotatet to engage into the eye parts s of the bail (Figs. 4 and 5) to lock the parts together. By rotating the ring to 'enable its split part i to successively clear the fork branches the stick can be withdrawn.

To the casing a is fixed a plate 2. This plate 2 is cast or provided with arms by g which the plate is attached to the vside of the l casing. This plate 2 is thus supported by its arms at a certain distance from the casing so i as to leave room in which to place the arms 8 supporting wheels 7. This plate with the l adjacent wall of the casing is slotted at 3 to form a loose bearing at each side for the gudgeons 3 to not only turn but also have pla or movement up and down. As these gudygeons carry the brush or rotary broom 4 such broom can come to the floor as presently seen.

shaft of a gear 5 which en ages the ear part or rings 6 of wheels 7. T ese wheeTs. 7 have rubber or like tires to get a grip on the surface over which they run. Said wheels 7 have their axles mounted' on carriers 'or swinging arms 8 pivotally mounted on the gudgeons 3. These arms 8 have a loose pivot or fulcrum connection with the plates 2 formed by pin and slot connections, the pins being shown at 9. These arms 8 as seen in Fig. 2 are of U-shape so as to extend on both sides of wheels 7 and said arms as seen in Fig. 2 support both ends of the axle of each of ,said wheels. These arms are pivoted on gudgeons 3.

lVhen the device is set on the floor or carpet the wheels 7 touch the ground and the gudgeons to sink and carry the brush to the car et or floor.

adjuster or screw stein 10 with nut 11 arrested by a shoulder or eye on plate 2 can be made to limit the swing or drop of gudgeons 3.

shoulder of the stick sits the rotatable split Each gudgeon is keyed to the hollow` arms 8 swing about fulcrum 9 to allow the l of gear 5 forms a feather connection.

On running the device along the rotating wheels 7 by gears 6 and 5 rotate the gudgeons with the brush 4 to give a 'positive motion.

The gudgeons 3 feather in the hollow hubs of gears 5 and when the gudgeons are held back against the action or pressure of springs 12 the brush can be withdrawn or replaced.

As the casing has practically no opening except the small slots 3 allowing play of the gudgeons 3 no dust can escape. The slots through which the gudgeons 3 pass do not extend through the bottom edge of the end walls of the case, but as seen in Fig.- 6, such slot is of limited extent.4 In practice, it has been found that such slots need not be more than three-quarters of an inch in length by three-eighths of an inch in width. Practically no dust can escape from the casing through such small apertures.

The gudgeons 3 can be retracted against the action of spring 12 by a pin or peg 14 (Fig. 3) which forms a finger piece and 'which peg also engaging a slot in the hub When said gudgeons are released the spring 12 forces these gudgeons back to engaging position.

Now what I claim is:

1. In acarpet sweeper, a bail having parallel uprights provided with eyes, a handle provided with oppositely arranged grooves in its lower end and a shoulder near its lower extremity, said uprights adapted to fit in said grooves and said shoulder being located belowand adjacent to said eyes, and

' a locking ring adapted to pass through said eyes and engage said shoulder.

2. A carpet sweeper comprising a casing provided with vertically elongated bearings, gudgeons adapted to turn and lay in said bearings, carriers swinging on t e gudgeons and wheels on the carriers geared to the gudgeons, said gudgeons being spring pressed or yielding to releasably engage a brush.

3. A carpet sweeper comprising a casing having its sides provided with bearing slots of limited extent so as not to pass through the bottom edges of said casing, a rotary brush in said casing, gudgeons connected with the brush and extending outside the casing and adapted to turn and play in said bearing slots, carriers swinging on the gud.

geons and wheels on the carriers geared to the gudgeons, said carriers and wheels all being outside of andfree or clear from the casing so as to leave the side wall of the casing unbroken except at said bearing slots.

4. A car et sweeper comprising a casing provided with bearing plates, said casing and plates having vertical bearing slots, a rotary brush in said casing, gudgeons guided in the slots and detachably engaging the brush, and springs yieldingly holding said gudgeons in engagement with the brush.

5J A carpet sweeper comprising a casing provided with bearing plates, said casing and plates having vertical bearing slots, a rotary brush in said casing, gudgeons guided in the slots and detachably engaging the brush, traction wheels geared to the gudgeons, threaded stems connected with the gudgeons'7 eyes on said plates through which the stems loosely pass, and nuts adjustable on the stems to limit the downward movement of the gudgeons and brush. 4

In testimony whereof I have hereunto setV `my hand in the presence of two subscribing witnesses.
