receiver on the frame of a carpet sweeper as toeifect a self accommodation of said receiver to normal variations of level in a surface traversed by the sweeper.
Still another object is to provide a carpet sweeper with a handle having a bailpivotally mounted 151 in the sweeper frame and maintaining assembly of the sweepings receiver in such frame, and to adapt the receiver toswing on the bail from its horizontal position of use to a vertical position beneath the handle, when the sweeper is suspend- 20 ed by the latter.
A further object is to adapt the rotary brush of a carpet sweeper to sweep effectively, in close proximity to the legs of furniture or other uprights. 7
A further object is to journal a pair of wheels on a member forming a pivotal support for the sweepings receiver, and further serving to attach a handle to the sweeper.
A further object is to provide a comb to dislodge any sweepings that may adhere to s the brush, and to mount such comb in a novel manner, within the sweepings receiver.
These and various other objects the invention attains by the construction hereinafter described, and illustrated in the accompanying drawings, wherein:
Fig. 1 is a top plan view of the improved sweeper, with the cover of the sweepings receiver part- 1y broken away, and showing certain parts in 49 section.
Fig. 2 is a longitudinal vertical sectional view, taken upon the line 22 of Fig. 1.
Fig. 3 is a side elevational view of the sweeper. Fig. 4 is a perspective view of the same, with the pan removed.
Fig. 5 is a vertical section, taken on the line 5-5 of Fig. 3, showing the mounting of one of the drive wheels, and of the sweepings receiver and comb on the frame.
In these views, the reference character I designates a cylindrical brush, having journal members 2 rigidly projecting from its ends and mounted in a pair of spaced frame members. 3. The latter are preferably U-shaped and elongated in the direction of sweeping travel with their bight-s at their front ends. The forward portions of said members are engaged by the journal members 2 and their rear portions are apertured to removably receive a pair of aligned stud shafts 4.
Journaled on the stud shafts 4 are wheels 5 from which drive connections are established to the brush by belts 6, engaging pulleys lfast on the journal members 2. Said wheels and pulleys are positioned within the elongated openings formed in the frame members between their spaced, parallel parts, and are preferably formed with approximately V-shaped peripheral grooves,
snugly receiving said belts. The latter are preferably of rubber and tensioned to give them an ample driving grip on the pulleys. It will be noted that the bolts 6 serve in the dual capacity of drive elements for the brush and tread members for the wheels 5. The journal members 2 have knurled portions (see Fig. 1) which are pressed into the pulleys 1, as the journal members are inserted in the frame members 3.
The stud shafts 4 have short end portions, of slightly reduced diameter, projecting inwardly from the frame members 3 to mount a comb 8 which engages the brush to relieve it of adhering sweepings. Said comb is formed on its ends with aligned tubular socket members 9 within which said reduced ends of the stud shafts are inserted (see Fig. 1).
Pivotally engaging the outer ends of said socket members, is a dust receiver, comprising a pan I0, provided with a cover ll hinged at l2 to the frontend of said pan. Said pan comprises a bottom having its front edge spaced a short distance rearwardly of the brush bottom, a pair of side walls, and a rear wall, and is open at its front end. The sides of the pan are adjacent to the brush extremities, extending slightly forward of the brush axis,' and are notched at I3 to accommodate the journal members. Thus the latter limit pivotal play of the brush and frame relative to the sweepings receiver, and assure that the brush and frame will move with the receiver when the latter undergoes any considerable anular travel about the socket members 9. To accommodate said socket members, the pan is formed with oversize openings M in its side walls, preferably in the nature of vertical slots. Any escape of sweepings through such slots is prevented by closures l5 of felt or other suitable sheet material, vertically slitted to accommodate said rod. The sweepings receiver drags, at its rear end. on the surface traversed by the sweeper,
and to minimize the drag, it is preferred to form the receiver bottom with a circular depression is in each of its rear corner portions to rest on said surface.
At its forward margin, the receiver bottom is preferably bent rearwardly at an upward inclination to form a sweepings retaining lip l1, and a second lip l8 may extend rearwardly and upwardly from said margin, above the lip H to retain such sweepings as fail to enter the pan on encountering the lip I1.
The teeth of the comb project forwardly, with a downward inclination of approximately forty five degrees, to engage between the brush bristles, (see Fig. 2) and to maintain it so positioned, its ends are formed with a pair of upstanding lugs I9 each terminally formed with a tongue 20, bent to loosely engage in a vertical slot 2! in the adjacent wall of the pan. Thus the comb is held from turning about the axis established by the socket members 9, but does not interfere with the intended vertical play of the sweepings receiver relative to said axis.
Straddling the sweepings receiver and pivotally mounted in the frame members 3 is a substantially U-shaped bail member 22 to which a wooden or other handle is centrally rigidly attached in any desired manner. The ends of said bail member are bent toward each other, as indicated at 23 to pivotally connect with the frame members, and this connection is established, preferably, by inserting said ends in sockets formed in the outer ends of the stud shafts 4 (see Fig. 1). Thus said bail member serves to hold the stud shafts in their positions of use and in supporting relation to the comb, and upon removal of the bail member, the stud shafts, comb, and sweepings receiver are freely removable from the sweeper. It is preferred to form the bail member of heavy spring wire, whereby the ends 23 may be very quickly snapped into or out of the stud shaft sockets.
The described manner of connecting the sweepings receiver, comb, stud shafts, and bail to the frame member lends itself to a very rapid initial assembly, and simplifies and facilitates inspection, cleaning, and any necessary repairs or replacement of the specified parts.
The pulleys 1 are of course considerably less in diameter than the wheels 5, so as to insure proper functioning of the brush. A two to one speed ratio between the pulleys and wheels is found to secure very satisfactory operation.
The bail is preferably formed with offsets 24 in each of its legs, positioned to encounter the forward ends of the frame members, when the bail is swung sufficiently forward, to establish the proper relation of the bail to the sweeper for employing the handle to carry the sweeper or hang it on any support. When so carried, the contents of the receiver will readily discharge, upon uncovering the pan as indicated in dash lines in Fig. 3.
Upon the forward end of each frame member, it is preferred to mount a bumper 2'5 of rubber or the like, to avoid scarring of any piece of furniture against which the sweeper may be thrust.
It is to be noted that the described construction leaves the brush completely unobstructed, forwardly of its axis, by any other parts, and consequently the brush may be so driven against any upright, as a furniture leg, as to sweep any dirt cleanly away from the foot thereof, the forwardly projecting bristles flattening out against the leg to permit such an operation.
The fact that the dust receiver, frame members, comb, and wheels of the described sweeper may be produced as sheetmetal stampings, permits very economical manufacture of the sweeper, as does likewise the rapidity and simplicity of its assembly.
It is believed a unique feature of the construction that the brush, of itself, is adapted to hold 5 the two frame members in properly spaced relation, any shifting of the frame members axially of the brush being prohibited by the rigid mounting of the pulleys l on the journal members 2 within the elongated openings of the frame mem- 10 bers.
The frame members may be formed with one or more holes 26 between the stud shafts and brush, as a provision additional to the sockets of said stud shafts for mounting the bail in the frame 15 members. A greater downward pressure may be applied to the brush through the bail, where the latter engages in the holes 26. When the bail member is received by the holes 26, it no longer serves to hold the shafts in place, and under 20 such conditions the-frictional engagement of said shafts in the socket members fl will, of itself, exercise that function. When the bail is moiinted, as shown, in the studs, retention of the latter is more secure, since the bail then supplements fric- 5 tional restraint on the shafts.
It will be noted that the forward portions of the side walls of the sweepings receiver, in projecting beyond the receiver bottom, have their lower edges 21 curved upwardly toward their 30 front ends, whereby the receiver is adapted to readily ride over the rugs or other obstacles encountered by said edges.
Preferably the bottom is formed with a pair of shallow downward proturberances 28 adjacent to its front edge and near the extremities of said edge. These prevent said edge from sinking into the nap of a rug far enough to unduly oppose advance of the sweeper and subject the nap to undue wear.
