CLEANING-TOOL.

Specification of Letters Patent. I Patented Jan, 2.1 1911,

Application filed November 8. 1908. Serial No. 460,933.

To all whom it may concern:

Be it known that I, Ina H. SPENCER, a citi zen of the United States. and a residentof Hartford. in the county of Hartford and State of Connecticut, have invented a new and Improved Cleaning-Tool, of which the following is a specification.

My invention relates to the class of tools I more especially employed in the remoral of z in the accompanying drawings. in which- T is a bottom view of the tool.

that. this tool shall have more or less ttcxiof the seats and desks. and as it is liable to dirt, dust and'the like by means of a current. 1 of fluid passed through the opening at the mouth of the tool, and the object of my in- E vention is to provide a. device of this class 2 having novel featuresof advantage and utility. A form .of tool in the use of which these objectsmay be attained is illustrated Figure l is a perspective view of a tool embodying my invention. Fig. 2 is a view in central cross-section through the same. Fig. 3 is a viewin central longitudinal section through the tool. Fig. l is a view in cross-section through the tool at a point between its center and the end. 'l ig. 5 is a detail view showing the metallic shell. Fig. 6 is a detail view in central cross-section through a modified form of the device. Fig.

My improved tool forming the subjectmatter of this invention is more. especially designed in conncction with apparatus in which a current of fluid. usually air. is employed for dislodging the dust and other matter to be removed in the cleaning operation, the preferred method consisting in causing a tlow of air or other tluid' ill\\:\l'tl at the mouth of thc tool. In order to uttallt' the best results the tool should be of considerable length. and in use as upon a tloot around articles of furniture it is desirable bility. This will be apparent when its use in connection with the cleaning of a schoolroom for instance is considered. as the tool must be moved in and out bctwccn the legs catch upon these Obstacles a flexibility of a greater or lesser degree will enable the tool of furniture. The tool herein shown and described is especially constructed for such uses. it. being so made that it.- will yield to a considerable degree to enable it to be disengaged from any obstacle or to pass be- -midway of the length; as

tween obstacles located ata distance apart less than the length of the tool.

.In the accompanying drawings the numeral T denotes a shell made of any preferred kind of metal. this shell having a chamber S. the entrance to this shell tcr minating in lips 9. hub 10 projects from this shell and is properly constructed for attaclunent thereto of a nipple- 11. this nipple being constructed to receive a handle. hose or other proper conductor for a current of fluid. The tool herein shown is especially designed for attachment of a rigid handle to which the hose or other-conductor is secured.

,The body part of the tool or casing 1:2 is constructed. as to its greater portion. of rubher, and in order to give this rubber the proper qualities as to stiffness itis reinforced throughout its walls in any suitable manner. This body part completelyincloses the shell 7. said body part having an opening snugly fitting about the hub 10 and through which said hub projects. i

In the preferred form of construction the casing is reinforced by CICSS-bltlCCS 13 of U- form. These. braces are preferably composed of pieces of wire embedded in the 'wall of the casing and extending downward on opposite sides to a proper distance from the edge. While this form of bracing or reinforcing the rubber casing is preferred. any means of accomplishing this result and that will allow proper flexibility in the re quircd directions will be considered as coming within the scope and intent of the invention. That part of the hub 10 projecting beyond the casing may be covered by a sleeve ll of rubber or like comparatively soft material. if desired.

The. lower edge of the tool is curved lengthwise. as plainly shown in Figs. 1 and 3 of the drawing. As hereinbeforc stated. it is desired that a tool of considerable length shall be employed in order to obtain the best results as to etliciency.

This tool will also be of little depth merely sutiicient to provide a chamber to accommodate a sufiicient volume of air.

' The mouth 25 of the tool extends for practically its whole. length and is'cnlarged or widened at that. portion underlying the outletfrom the chamber in the tool. preferably shown herein.

This provides means whereby the tool will handle the comparatively larger pieces of dirt or litter without such undue enlargement of the mouth as to impair the efliciency 5 of the tool at the extreme ends of the slot I curved as at 15 as above described and shown in the drawings. When a rolling surface is encountered the curved edges of the tool will accommodate such rolling surface. *When the tool is operating upon a flat surface of the 'floor,.or should a depressedportion be'encountered, the suction, owing tothe flexibility of the tool, will cause the edges of the tool to assume close contact with the surface all around the inlet opening, audit will thus be seen thatthe tool,

, owing to such flexibility, has superior {ldw vantages in the cleaning of surfaces of more or less irregularity or unevenness, and this without necessarily involving a curved edge. A tube 16 of rubber or like soft material may be placed over the nipple 11 if desired.

In the form of construction shown in- Fig. 6 the body part of the tool is formed in the same manner as above described, of

rubber withlthe bracesdisposed throughout the walls of the body part in a manner hereinbefore described for stifl ening purposes and at" the same time to allow flexibility. The shell 17, however, has only a short hub 18. A plate 19 is secured outside of the body part 12 as by means of screws 20 passing through the plate and into the shell 17. 'This plate has a tubular' extension. 21 to which the nipple 11 is pivotallyattached as hereinbefore described. In this form of construction the flexible body part of tlie tool is given added rigidity at the point of location of the inner shell and also connection of the tube 11. The tool is therefore highly efficient in itsoperation owing to the fact that its edges may be' easily brought into contact with the surface of the floor at all times and for thefurther reason that the flexibility of the tool in other directions enables it to be readily disengaged from obstructions encountered in the cleaning operation. While the preferred form of construction embodies the edges; of the inlet into the tool curved inward, or concaved, I do not limit myself to the edges curved in this direction, as beneficial results-will flow from other curved forms of this edge.

While 1 have shown and described herein the preferred means of embodying my invent-ion in a tool of the class described, such construction may be departed from to a greater or lesser extent without avoiding the invention, and I do not desire to limit myself to the precise means herein shown and described.

I claim 1. A cleaning tool including a flexible body part of long, narrow proportions as to the partadapted to restupon a surface to be cleaned, said body part having a chamber of little depth as compared with the length and with an inlet opening to said chamber and an outlet therefrom, and means on said body part for connection of a tubular conductor. r 2. A cleaning ..tool including a flexible body part having a chamber thereinwith an inletthereto and an outlet therefrom, and means for preventing collapse of the walls of the casing by reason of the reduced pressure therein. I
