.Itpplication filed July 31,
lhis invention relates particularly to means for adjusting a nozzle of a suctionsweeper by raising and lowering the same with relation to the surface to be operated 5 upon.
It is common practice in the manufacture of sweepers to provide at the front part of the machine a pair of axially-arranged sup. porting rollers or wheels adjacent the nozzle 19 and to provide one or more supporting wheels positioned toward the rear of the machine. To raise or lower the nozzle with relation to the carpet or object to be cleaned. means are provided to raise or lower the axis of either the front or rear wheels. An object of this invention is to provide means, of improved construction, for adjusting the axis of one of the supports of the device and which shall be positive in its operation and simple in its construction.
@ther objects are to malzethe adjusting device quickly and easily operable to secure the desired adjustment, and to so construct the same that it will be very securely held in adjusted position to maintain the nozzle in any position given with relation to the surface to be cleaned.
The above and other objects will become apparent from the following description taken in connection with the accompanying drawing, in the different figures of which the same reference numerals indicate like parts.
In the drawings:
Figure 1 is a side elevation of a suctionsweeper showing the application of my in vention; I
Figure 2 is a detail view showing the supporting bracket for the adjusting mechanism; and
Figure 3 is an enlarged sectional view through the adjustin mechanism parts beingshown in elevation.
Fig. l is a bottom plan view of the sweeper with minor details omitted.
Fig. 5 is a detail section of the spring ball retainer latch.
Designating the parts by reference characters, indicates the motor-housing, ll
the fan chamber, 12 the take-nozzle, the discharge-spout. The a ove elements essential parts of practically suctionsweepers manufactured. The tan-cnarnner dischargespout 3.3
are usually cast as'al. -utegral or so 1922. Serial llo. 578,723.
rigid frame the intakewheels l4: l5 suitably and preferably positioned to run between the paths of the wheels l i area pair of axially-separated wheels 16. To raise and lower the intakenozzle with relation to the surface to be operated upon.'rneans are provided for vertically adjusting the axis of the rear wheels 16.
My invention is concerned with novel mechanism for raising and lowering the rear portion of the frame of the cleaner and with rneans for securing the adjusting mechanism securely in adjusted position.
A particular structure for accomplishing the object-sol my invention will now be described.
The rear portionv of the frame of the cleaner is supported on wheels 16 which are secured beneath the discharge-spout 13 by means of a bracket 17 which is secured to the underside of the discharge-spout by screws 18. The lower end of bracket 1? carrise a pivot 19- on which is mounted link 2O carrying at the other end thereof an axle 21 on which the rear wheels 16 are journaled. M unted. on one end of axle 21 is the adjusting member 22. A double screw-thread 23 is cut on the intermediate portion of rernber 22 and the upper end is reduced as t for a purpose to he more fully denear the outer ends of which are provided holes 33. and 32 for the reception of pivot pins 33 and 3 1-.
Pivoted on pins 33 and. 34 between the and is an annular ring 35 having opening 36 therethrough; On. the provided a number isle of ring 35 is 'ddepressions 37 the purpose of he more fully explained later.
"*or mounting ring 35 on truni the fact that as adjustment o eels is made by screwing nut i threaded portion 23 of the. in er 22, this member takes difi. relations with respect to the tit? spring-pressed latch means, the trunnioned member having indentations in a face thereof adapted to be engaged by latch means said washen,
carried by the nut, the nut being provided with means for limiting the movement of the adjusting member in one direction, said means comprising a counterbore having a forced fit washer inserted therein, and means on the adjusting member to engage Signed at Chicago, in the county of Cook, and State of Illinois, this 6th day of June,
