- 1 This invention relates tea .device. for: cleaning theatres, auditoriums and. the like, and: has. :for an object the provision of a relatively simplerinexpensive device .adapted to reduce i the i labor.
time and expense involved inperforming the i various cleaning operations.
To properly-cleana theatre, it is neoessary to remove the trash from .the .floor and .seats,. to
. clean plushseats with a vacuum cleaner, and-to spray-the floor andseats with a germicide. Heretofore, in performingathese, various operations, brooms andbrushes were employed for sweeping trash from thefioor andhouseholdetype vacuum .cleaners were employed for cleaning. thapliish seatsand for spraying the germicide. The time, effort and expense hereto-fore involved in removing trash from around and betweenthe. legs. of theatre seats by means of .brooms. and brushes, and incleaning and spraying seats by meansof household-type vacuum cleaners, is well known to those engaged in managing theatres.
The present invention contemplates the provision of an operable motor-blower unit adapted to be carried by the operator by means or a shoulder strap, the unitbeing'provided with an improved attachment for dislodging and collecting into an accumulated pile all the' boxes,paper andother" trash usually foundaroundand' between the legs of theatre seats at "the :end" bf a performance. Spraying'and vacuum cleanenat- "tachments are also provided for the unit, "thus providing a single unit adapted toreduce the labor and expense-of 'each of the several operations requiredin cleaning theatres.

L-shaped recess 28 to receive the head portion 21 of a pin 28. The pin 28 is mounted in an aperture provided in the conduit l6 and is adapted to be engaged in a slot 29 formed in the inner end of the nozzle H. The pin 28 serves to prevent rotational displacement of the nozzle l'l relative to the conduit l6.
The nozzle I1 is formed with an air passage-, way having a smaller cross-sectional area than the conduit l6 for the purposeof increasing the velocity of the air leaving the nozzle. The neck portion 3| of the nozzle is preferably formed circular in cross-section and intersects the outlet portion 32 which is formed to provide a passageway of gradually increasing width and gradually decreasing height to create a relatively fiat stream of air for passage alongthe fioor of a theatre. As illustrated in Fig. 3, the outlet portion 32 of the nozzle is disposed at an angle of approximately 60 from the longitudinal axis of the neck portion 3|.
In using the device thus described in cleaning a theatre, the motor-blower unit is supported upon the operator by means of the shoulder strap l3, and the rigid conduit I6 is disposed at an angle of approximately 30 to 45 from a vertical plane to direct a flat stream of air along and parallel to the fioor. As illustrated in Fig. 1, it will be noted that the nozzle end of the conduit [6 is adapted to be inserted between and around the legs 33 of seats 34 to dislodge and remove boxes, paper and other trash Without causing the operator to bend over. As the operator moves along between rows of seats, the stream of air passing from the nozzle l'l causes the trash to be blown toward a predetermined spot from which the trash may be collected for removal in suitable containers. The device thus described is also adapted for use as a vacuum cleaner for cleaning plush seats by attaching a dirt receptacle to the tangential air outlet II and attaching a vacuum cleaner hose to the air inlet 9. The device is also adapted for use in spraying germicides or insecticides by attaching a suitable spraying de- The construction, method of attachment and operation of vacuum cleaner attachments and spraying attachments on devices of this type is well known in the art and does not require further illustration or description.
While this invention has been shown in but one form, it is obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modifications without departing from the spirit and scope of the claimed invention.
