VACUUM CLEANER WITH HEADLIGHT Bernard P. Smith, Newark, N. 1., alsignor to The Regina Corporation, Railway, N. 1., a corporation of New Jersey Application April 27, 1935, Serial No. 18,517

10 Claims.

The invention relates to vacuum cleaners of the usual household type consisting of an ambu- 7/ lant frame, motor, suction fan, suction nozzle, dust bag, and a handle attached to the frame for guiding the cleaner over the surface to be cleaned.

More particularly, my invention relates to a vacuum cleaner provided with means for illumihating the surface to be cleaned immediately in advance of the cleaner and including the forwardly projecting nozzle of the apparatus. Such means of illumination comprises a headlight secured to the frame in such position as to serve most eiiiciently the purpose hereinabove indicated.

'Among the objects of the invention is the provision of such illuminating means which is of compact and simple construction, inexpensive in cost of manufacture and attachment to an 20 existing type of vacuum cleaner and which in the courseof use of the cleaner for any of its intended purposes will not interfere with such use.

More specificobjects of the invention are to provide a mounting for the headlight which is capable of easy manipulation for the purpose of swinging the same out of position so as to make possible the attachment to the vacuum cleaner of the various accessories, particularly a suction hose to be used in cleaning articles of fumiture, draperies, etc.,- in accordance with the normal application of such accessories to the ambulant frame of the cleaner.

' A still further object of the invention is to provide a headlight mounted upon the forward portion of the fan and motor casing of the horizontal type so that such 'headlighti and the mounting thereof will not increase the over-all height of the, vacuum cleaner and thereby inter- 4o fere with the normal use of such apparatus in cleaning under articles of furniture and places ordinarily inaccessible by vacuum cleaners of the vertical motor type or cleaners of the horizontal motor type to which may have been ap- 45 plied accessories including a means of illumination superimposed upon the casing.

In accordance with my invention, there is also provided a means of circulating air drawn into the vacuum cleaner by the suction fan through the headlight casing surrounding the electric light bulb secured therein for the purpose of providing a continuous stream of cold air effective to cool such bulb and to retain it at a normal temperature and without excessive heating thereof.

Further and more specific objects of the invention will appear to those skilled in the art from the following description, taken in conjunction with the accompanying drawings, in which Fig. 1 is a plan view of a vacuum cleaner to which my invention has been applied, showing only the base portion of the propelling handle and without showing the dust bag used in conjunction with the cleaner; Fig. 2 is a side elevation of the cleaner; Fig. 3' is an end view of the cleaner from the suction nozzle side thereof showing the headlight and mounting in position upon the frame; Fig. 4 is a view similar to Fig. 3 showing the headlight mounting turned about its pivot to enable the suction pipe used for cleaning surfaces remote from the ambulant frame to be applied to thefan casing opening; Fig. 5 is a vertical section through the headlight casing along the line 5-5 of Fig. 6; Fig. 6 is a section on the line 6--6 of Fig. 5; Fig. 7 is a rear view of the headlight mounting, showing more clearly the electrical wiring therethrough; Fig. 8 is a section on the line 8-4 of Fig. '7; and Fig. 9 is a detailed enlarged section of one of the contact elements between the electric light bulb and the electrical wiring within the. headlight mounting.

Referring more particularly to the drawings, in which similar reference characters identify similar parts in the several views, I0 is the ambulant frame of the vacuum cleaner comprising a housing ii for the horizontal motor and a suction fan housing l2. The frame l0 and motor housing ii are mounted on pairs of wheels I! supporting the forward'end of the frame and a pair of wheels ll supporting the rear portion of the frame and more particularly the motor casing Ii. A downwardly turned suction nozzle i5 protrudes forwardly from the ambulant frame. From the fan casing i2 extends a dust discharge pipe ii to which is connected the usual dust bag (not shown) used with this type of vacuum cleaner. Pivotally mounted upon the shaft, near the ends of which are secured the wheels I, is the forked member [1, to which is connected the tubular handle IS. The various other details of construction of the vacuum cleaner per se are not herein described, said structural details and accessories being no part of this invention.

Upon the front face of the ambulant frame It and upon anupturned projecting portion IQ of a housing forming such front face immediately forward of the fan casing is pivotally sepreferably cast integrally with a housing 22 within which is secured, as hereinafter described, the electric light bulb 23. The housing 2| and its projecting portion 22 may be made of any suit-'- able material but I prefer to make such element of Bakelite or similar phenolic condensation product or composition material.

The casing 2| is secured to the housing 20 immediately above and on the center line of the opening 24 which is adapted to receive the end of a suction pipe of the type used for cleaning surfaces or materials remote from the vacuum cleaner and therefore from its suction nozzle, suction being applied to the surfaces to be cleaned through such suction pipe by means of the'fan and motor of the vacuum cleaner.

For the purpose of mounting the casing 2| in the position indicated, I provide such casing with a projection 25 having an aperture 26 through which and the projection extends a securing bolt- 21 surrounded by a compression spring 28. From an examination of Fig. 6, it will be noted that in order to turn the casing 2| from its position there indicated, in which it covers the opening 24, to the position of such casing indicated in Fig. 4, in which the opening 24 is uncovered by the casing and made available for application thereto of the suction pipe, it is only necessary to grasp the casing 2| at the two ends of the housing 22, exert a slight pull thereon so as to compress the spring 28 within the projection 25, and then rotate the casing, 2| about the securing bolt 21.

A structural feature which is an important element of my invention is that the protruding portion constituting the housing 22, acting as the hood for the electric light bulb and a casing therefor, is so positioned with respect to the remaining portion of the casing 2| that the greater part of'portion 22 lies substantially above the horizontal center line of the casing, so that the housing 22 may be grasped at the ends thereof by two fingers and the casing 2| withdrawn from contact with the front face of the ambulant frame without binding. In other words, if the protruding portion or bulb housing 22 of the easing 2| were not precisely or substantially in the position thereof indicated, but, for instance, were lower upon the casing 2|, when such projecting portion was grasped by the fingers, the casing 2| in the course of its removal from contact with the portion 2|] and therefore disengagement of its conductors, would be given a slight pivotal movement about a point near its upper extremity, which movement would result in a-bincling of the casing, making it difflcult to rotate the same about the securing bolt 21.

Turning now to a. description of the mounting of the electric light bulb 23, it will be noted from Figs. 5-8 that the housing 22 is formed with an internally projecting socket element 29, within which is adapted to be seated the socket member 30 of the bulb. Within the socket element 29 are provided two contact members 3|, 3| of the construction shown in enlarged detail in Fig. 9 and including a metallic housing 32 within which is secured the end of a conductor 33.- A spring 34 is mounted within the housing 32, one end of which is in contact with the end of the com ductor 33 and the other end of which is effe to press contact element 35 outwardly fro it e housing and against the contact in the lease of the socket 30 of the electric light bulb.

From the upper contact element 3|, a c tor 33 is led through a preformed recess wardlynear the other end of the housing to a contact 36 inthe front face of housing 20. From the lower contact element 3| a conductor 33' leads to the contact 31 on the housing 20. It will be noted (see Fig. 8) that the ends of the conductors 33 and 33' are provided with a slit 34 for insuring absolute contact when such conductors are inserted into the depressed portions of the housing 20 provided with the

contacts

38 and 31. Such contacts, being depressed, leave the surface of the housing 20 smooth and unobstructed.

The end of the housing 22, remote from the end thereof provided with the internal socket 28, is provided with a cap or plug 38 of the same material of which the member 22 is constituted. The cap 38 is provided with a recess 39 within which is placed a compression spring 40.

An important feature of my invention is the novel manner in which the bulb 23 is secured within the housing 22. The socket of the lamp 23 is of the sliding-fit type and in accordance with my construction it is only necessary to slide the socket of the light bulb 23, which is of the double contact type, into the socket projection 29 and thereafter apply the cap 38 with the spring 40 positioned within the recess 33 to the housing 22, thereby pressing the light bulb 23 inwardly, by means of such spring. The cap 38 may then be secured within the housing 22 by means of a screw 4| projecting through the side of the member 22 and adapted to contact the peripheral surface of the cap and thus secure the latter in its seat.

The novel mounting of the electric light bulb 23 just described, constituting a comparative loose fitting thereof within the housing-22, provides with may be termed a floating support of the bulb, as the latter is supported between two spring mountings, one of such supporting mounts consisting in the resilient contact elements II and the other in the spring 40. The bulb is thus snugly fitted in a position in which it is capable of withstanding the repeated shocks to which it is necessarily subjected during the vibration attendant the operation of the vacuum cleaner. The bulb being floated, as it were, upon its resilient supports will have a longer life than if it were secured within the housing in any ordinary manner.

For providing the necessary ventilation to keep the light bulb 23 cool during the operation of the vacuum cleaner, and while such bulb is lighted, I provide an aperture 42 extending through the housing 22 from the bulb chamber through the rear wall of such housing, to the opening 24 in the front face of the frame. During the operation of the vacuum cleaner, therefore, and whenever the bulb is in lighted condition, a continuous stream of cold air is drawn inwardly through the opening 43 in the housing 22, such air circulating around the electric light bulb and cooling the same and then through the opening 25, such air being drawn into the apparatus by means of the suction fan. The amount of air necessary tocool the bulb, and which is drawn through the aperture 42 is extremely small and hence does not interfere with the normal operation of the vacuum cleaner.

will be noted that the member 22, housing electric light bulb, extends downwardly so as to substantially cover such bulb and protect it iron "njnry, should such member come into cont h any'protrudlng object. Such member, serving as a hood, will also protect the electric completely surrounds the bulb, except at a region light bulb from injury from any falling object. The opening 43, as shown clearly in Fig. 3, is of sufficient length to illuminate the surface forwardly of the ambulant frame and to a certain extent on each side of the suction nozzle. The position of such light aperture is such that it is effective to permit the casting of light upon and forwardly of the suction nozzle so that the operator of the vacuum cleaner has at all times a full and clear view of the suction nozzle as well as of the surface over which such suction nozzle and the vacuum cleaner proper are being propelled.

In Fig. 1 is shown in dotted lines the electrical wiring for the'illuminating means from which it will be seen that the wiring from the two

contact elements

36 and 31 are passed through the fan casing near the inner side surfaces thereof and along the inner surface of the motor casing II. On the side of the motor casing is mounted a switch 44 controlling the circuit to the headlight. The provision of this switch makes it possible to use the vacuum cleaner without the headlight at such times as no artificial illumination is necessary in conjunction with the use of the cleaner, or at such times as the apparatus is used for remote cleaning purposes when the headlight casing is swung out of. position to permit the attachment of the suction pipe.

While I have shown and described a particular embodiment of my invention, it is obvious that various changes therein, particularly in details of construction and in the arrangement of the several parts may be made without departing from theinvention.
