Figure-"1 a front view f the suction cleamer with floor-illuminating means embodied" therein- Referring to the drawings, there will be described a preferred embodiment of a modern low cost suction cleaner of the horizontal axis type to which the invention has been applied. The suction cleaner comprises a suction nozzle I5, and a fan chamber I6 which houses a suction-creating fan II. The chamber I6 is interiorly connected through a fan eye I8 to the floor-contacting nozzle I in order that it may draw cleaning air therethrough to remove the foreign matter in the surface covering and discharge it through an outlet I9 into a suitable dust bag (not shown) as is well understood. A motor casing is rigidly attached to the fan chamber houses a suitable driving motor for the suctioncreating fan [1. A suitable form of agitator mounted within the suctionecreating nozzle I5 may be suitably driven by means of a belt ac- I6 and tuated from an extension 2i of the motor shaft.

Front supporting wheels 22, 22 and rear wheels 23,23 make possible the easy movement of the cleaner over the surface covering upon the exertion by the operator of a slight force through a handle (not shown) mounted upon a pivoted bail construction 24 operatively connected to the motor housing. Handle detent means 25 permits adjustment of the handle from its nonoperating vertical storage position to its operating position.

A suction passage 28 provides for the passage of dirt laden air from the suction cleaner nozzle I5 to the fan eye it. The belt which drives the agitator also passes through the suction passage 26. Immediately in front of the fan eye I8 is a converter opening closed by a suitable closure 21 which seals the suction passage from the atmosphere. When the closure 21 is removed a converter attachment may be inserted through the opening so as to communicate with the fan eye I8 in a manner well known in the art. The

cleaner is also provided with a furniture guard cleaner,-it is also essential in the design of such asuctioncleaner that the over-all height of the machine be as low as possible. This requirement is essential when it is considered that the lower the-machine is to the floor the greater will be its field of usefulness as it can be used under a greater number of heavy objects such as furniture which are normally positioned upon and overlying the surface covering to be cleaned. In addition, it is further essential that the nozzle I5be as free of obstructions as possible. example, the suction passage and fanchamber should=;be positioned rearwardly of the front edge of the nozzle to permit the nozzle to be readily moved about and underneath the furniture during the cleaning operation. In order to preserve the low height of the cleaner without-increasing its width the main casting is provided with symmetrically positioned pockets 39 spaced laterally of the fan chamber It to the rear of the suction passageway 23 above the nozzle I5 as is illustrated in Figures 1 to 3, inclusive. As shown in Figures land 3, the pockets 30*are positioned equal distances from the converter opening cover plate 21 on opposite sides thereof. Each of the chambers 30 is provided with an ornamental louvered closure plate 3I which may be formed from sheet'metal or plastic and which is readily snapped into position with an extension 32"fitting theopening 33 to each chamber 30. The left hand chamber as viewed in Figures 1 and 3 is a dummy chamber covered with a louvered closure plate 3I to hide the exhaust outlet so as to preserve the symmetrical appearance of the cleaner.

The walls of the right hand pocket 30 are so shaped and curved that they form reflectors adapted to throw light beams forward of the nozzle I5 and across the entire width thereof as indicated by the dashed line 34 in Figures 2 and 3. The closure plate 3i is provided with suitable louvered openings 35 so that light beams are projected forwardly and downwardly from a bulb 36. The bulb 36 which may be a standard bayonet joint type is mounted in a bayonet joint socket 37 formed integrally with an extension of the plastic motor casing 29. A passage 39 extends laterally from the casing 20 and serves to connect the socket 3'! to the interior of the motor housing 20.

The passage 33 forms a chamber for receiving spring contacts 45) and 4I the inner ends of which are secured to the wall 38 of the casing 29 by means of screws 44 threaded into insulating lugs 42. At their inner ends the spring contacts are electrically connected into the motor circuit by lead Wires 43 also secured by the screws 44. The outer ends of the spring contacts make resilient contact with the contacts of the bulb 36 and serve to hold the bulb in the socket 31 in a manner well known in the art. The front wall 38 of the motor housing 26 is suitably ribbed at 45 to form the rear walls of the chamber 30 and of the fan chamber I6. An ornamental plug 46 serves to form a closure for an opening 471 formed during the molding operation.

The closure 3| may be removed by pulling out wardly so as to disengage the portion 32 from the edges of the opening 33 and the catch 48 from the opening 49 in the top of the nozzle I5 whereby access may be had to the pocket 30 in order to install or replace the bulb 33 in the usual manner.

The bulb 36 is located at substantially the; The interior of the chamber 30 is coated with enamel or other horizontal axis of the motor.

reflective coating to serve as a reflector for directing the light rays emitted forwardly and downwardly across and in front of the suction nozzle at an angle onto the surface immediately forward of the nozzle I5, as illustrated sche-,

matically by the dashed lines 34 in Figures 2 and 3.

While I have shown but a single embodiment,

of my invention it is to be understood that this embodiment is to be taken as illustrative only and not in a limiting sense. I do not wishto be limited-to the particular structure shown and described but to include all equivalent variations thereof except as limited by the scope of the and operatively connected to the eye of said fan said passage being formed with a converter opening in front of the eye of said fan, said nozzle-- being the element of maximum Width of said cleaner and said fan chamber being the ele ment of maximum height, a reflecting chamber,
