15 Claims.

The object of the present invention is to provide an adapter or connector which may be connected directly to the suction nozzle itself of 1y attached or removed. I A further object is to provide a hose connecter which is especially adapted for use upon a welln the cleaner, and which may be easily and quickknown type of cleaner having a suction nozzle with inlet openings or ports for supplying air to the fabric being cleaned adjacent the inlet or suction mouth of the nozzle, as shown and de-,

scribed in the pending application; for l etters Patent filed by George W. Allenwand Lena, B. Allen on August 27, 1929, SerialNo. 388,729,.

With these objects in view the present inven; tion consists in the devices and combinations of devices hereinafter described and more particularly defined in the claims.

In the accompanying drawings which illustrate what is now considered the preferred form of the present invention as embodiedin-a hose connecter adapted for use on thesuction nozzle shown and described in said application, Fig. 1 is a side elevation of a cleaner with the adapter attached thereto; Fig. 2 is a top plan View on an enlarged scale of the front portion thereof; Fig. 3 is a transverse vertical sectional viewon r line 33 of Fig. 2; Figs. 4 and 5 are longitudinal, vertical sectional views on lines 4-4 and 5%5respectively of Fig. 2; and Fig. 6 is aperspective view of the hose connecter detached.

' The cleaner illustrated in Fig. 1 comprises the usual fan casing 6, with the forward and downward extension .7, flaring laterally into the nozzle '8. An electric motor 9 is mounted on the top of the casing, and the rear end of the machine is supported by the wheels 10. The dust bag 11 and propelling handle 12 are shown only in part. u I w The nozzle, as shown in said Allen application and as illustrated in Figs. 4 and 5 of the present drawings, comprises the inletslot or mouth 14 extending across substantially the entire width of the nozzle and communicating withthe interior of the fan casing 6 through the usual dust or passage within the part '7. Adjacent the nozzle; mouth at the front and rear are the air ports or openings 16 through which air: is detains the apparatus in upright position.

livered from the inlet ports 17 onto the surface of the fabric being cleaned to loosen any: threads or dirt upon or in the fabric and to carry the same into the suction mouth. An' endless rubber bumper band 18 is held in the recess of '60 groove 19in the front, rear, and end walls of the nozzle. i

In normal operation the front end of the cleaner is supported by the flat bottom faces 18 which form part of. the nozzle structure, all as shown and described in said Allen application. The adapter or hose connector which forms the subject of the presentinvention is adapted not only to coverand close the suction .or inlet mouth of the nozzle, but "also to cut off the air ports or openings at the" front and rear thereofu In addition it is provided with means for quickly and securely clamping on the nozzle where it supports the front end of the cleaner and main- 7 5 As shown in Fig. 6, 'the;adapter or connecter comprises a trough-shaped body portion having substantially vertical sidewalls 22'and a bottom consisting of the fiat end'portions 24 and'adeepor middle or intermediate portion 26. This intermediate portion has its, bottom inclined inwardly' from each 'end, as at 27, and curved downwardly and forwardly from the rear, as at 28. .At the bottom of the front Wallis' the tubu-k lar extension'or fitting 29 to receive the suction hose 30, as shown in Fig. 1. 7

At each end oftheadapter is a small air opening 31 in the vertical wall for the purpose of admitting a current of air which will prevent the lodgment and deposit of dust ordirtat the ends of the-adapter. I i

The adapter i is provided near each end with supports or legs 32-which consists of U-shaped members having a stiffening rib or lip 34 at each edge, the upperends of the vertical members being connected as by spot weldingto the front and rear walls. The height of these' legs is such that the adapter and front-end of the cleaner are supported solely by these logs, the lower middle portion 26 being above and out of contact with the floor or other surface; Owing to the wide 1 spacing apart of these legs on the adapter, the

cleaner is maintained securely in erect position without danger of being tipped over even when it .105

is drawn about by thehose. These supporting legs are of such a width and their front and rear bottom corners are Soroundedthat little resistance is offered to the movement of the cleaner and the latter may be drawn about by the hose with a minimum of efiort, even over deep pile fabric.

The converter is connected or attached to the nozzle by means of the spring clips 36 pivoted at their rear, ends to the top of the rear vertical members'of the supporting legs. These members are formed with two extensions or lugs at their tops spaced from one another and rolled over to provide the cylindrical supports 40 for the pivot pin 42. I

The free ends of the clips are formed with a rounded catch or shoulder 44 to engage'beneath the bead or out-turned lip 45 on the top edge of the vertical walls or the adapter. An extension or thumb piece as facilitates the engagement and disengagement of the catch or shoulder and the lip when it is desired to attach or remove the adapter. The horizontal or body portion of the clip is struck downwardly to form the rounded rib 48 to engage the top of the nozzle, as shown in Fig. 5, when the clip is in operative position, thus holding the adaptertightly onthe nozzle by the spring of the clips. 7 V a In normal operation of the cleaner, that is, when it is being propelled over a rug to clean the same, the adapter or hose connection is not attached andthe nozzle rests directly upon the rug. When however, it is desired to use the '3 flexible hosewith the hand tool, the front end or" the cleaner is slightly raised, the adapter with the connected hose already attached is positioned beneath the nozzle, which is then lowered into I place in the. trough-shapedbody 0f the adapter,

the spring clips are turned over the top of the ,nozzle and forced into operative position beholds the connecter and nozzle in close yielding engagement, with the rubber bumper band 118 compressed between the nozzle :and the walls of the converter to prevent any leakage of air downwardly therebetween. 1 By reason of the fiat bottom end portions 24, which when the converter is in position on the nozzle are inv close proximity tothe bottom of the nozzle, and of the. lower middle portion 25,

the cross sectional area of the air duct or passage through the converter is restricted and the formation of pocketsor dead spaces'is avoided, thus preventing reduction of air velocity and the resulting deposit of dust and dirt. w

' The converter, of hose connecter herein shown and described may conveniently be stamped from sheet material with corresponding light It is self-contained, that is, it has no loose or separate parts to be mislaid or lost, and requires no movable or disconnectible parts on the cleaner.

Whilethe adapter herein shown and described is especially designed for use with the nozzle of said Allen application, it is obvious thatit may be used with other types of nozzles, and may be embodied in other forms and arrangements within the scope ofthe appended claims.
