CLEAN ING-TOOL.

Specification of Letters Patent.

Patented an. '11-7, iota.

Application filed July 24, 1911. .Serial No. 640,237.

' To all whom it may concern:

Beit known that I, O'rro ELBE, a citi- 'zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cleaning-Tools, of

' which the following is a specification.

. matter of .shape having opposite V-shaped end por-' This invention pertains particularly to improvements in cleaning tools for use in connection with vacuum cleaners, and has for its object the provision of an article which will be particularly efficient in use and very cheap in manufacture.

An advantageous feature ofthe device is the peculiar formation of the base plate of the 'tool whereby the sliding action of the same in operation over surfaces to be cleaned is greatly facilitated.

.Still another object is to provide means cooperating with the base control the suctiontof the device when the tool is used in cleaning delicate fabrics or the like. I

With the above and other objects in view, this invention consists in the construction,

" combination, and arrangement of parts, all

as hereinafter more fully and illustrated in ings, wherein- I Figure 1 is a perspective view of the invention; Fig. 2 is a central cross section thereof; Fig.1?) is a longitudinal section;

described, claimed, the accompanying draw- Fig. 4 is a bottom view of the tool, and Fig. 5 is a fragmentary detail view showing one of the ball trunnions in section and the surrounding parts in side elevation. Throughout the following detail. descrip tion and on the several figures of the drawings, similar-parts are referred to by like reference characters. f

The improved tool forming the subject this invention is composed of a base plate or body portion 1, said base'plate being elongated and having its front and rear edges upturned, forming rearwardly diverging bearin surfaces at its front port1on and, forwardly diverging bearing surfaces atits rear portion. The body portion 5 .gf the plate 1 is formed with a suction chamerf2 at the central portion of which is an opening 3. Practically speaking, the body of the 'tool of this invention is of lozenge tions. Preferably formed integrally with the base land extending from the opening 3 is formed: the socket 4 having disposed plate to eifectively oppositely thereon the ears ,5, said ears having openingsor slots 5 therein. Pivotally mounted by means of the screws 6 passing through the slots 5 is the ball 7, said ball having an opening 8 in the bottom portion thereof which is of approximately the same size as the opening 3 in the base 1. Extending from the ball 7 is a sleeve or neck 9 into which is received a tubular operating handle 10 as shown, for properly conducting the current of air and dust or dirt. The pivotal mounting of the ball 7 permits the tool to be used in cleaning under and around furniture, while at the same time the operative area of the openingin the base plate may be regulated by upward or downward movement of the handle 10 connected to said ball. Furthermore, the pivots 6 upon the ball are preferably located to one side of its center, so that when the operating handle is raised, by reason of the fact that the distance between said pivots and the outer edge of the ball is greater on one side, said pivots will be caused to move slightly in arcuate slots 5 until they bind against the end portions of said slots and the outer portion of the ball binds against the lower portion of the socket, limiting in thismanner the upward movement of the handle and simultaneously regulating the size of the suction opening, as above stated. The slots 5' are of a suitable length to permit the opening 8 to'be nearly closed by this upward movement. The downward movement of the handleis limited by the contacting of the neck 9 with the rear portion of the socket, said portion being cut out sufficiently to allow the opening 8 to pass the opening 3 in the plate 1, and thereby close the suction opening in this direction.

From the foregoing, it will be noted that, by movement of the operating handle, the amount of suction may be fully controlled as desired for. use on floors, floor coverings, or delicate articles, such as curtains or the like, thereby preventing the latter, from bep the tool by suction of the ing drawn into cleaner.

The-article hereinbefore described can be very cheaply manufactured, and may be used in connection with hand or power Vacuum cleaners of any type.

It will be apparent by reference to the drawings that the ball and socket joint which connects the handle 10with the suction head of member 1, constitutes virtually a valve, the opening and closing of which movement of the parts 1 and 10.

It is obvious from Fig. 2 of the drawing will be readily controlled by the relative that the screws 6 are eccentric to the circle defined by a section of the ball 7 taken through the center of the opening 8 and in line with the axis of the neck 9. The screws 6 form trunnions which find loose bearing in the slots 5 whereby theball is permitted to have a range of revolution representing .substantially ninety degrees, the trunnions of the ball traveling longitudinally in substantially an arcuate path along the slots 5. during the partial revolution of the ball and limlting the amount of movement of vthe ball during upward movement of the handle by coming in contact with the terminals of the slots, the ball binding against that portion of the wall of socket 4 most remote from the respective ends of the slots 5 engaged by the trunnion.

It is apparent from Figs. 1, 2 and 3 of the drawing that the base or body portion 1 provides a suction chamber surrounded by the outline of the surrounding or confining edge and the walls of the said chamber are all inclined from every point toward the point of the discharge opening 3. That is to say, the walls of the suction chamber longitudinally of the body incline from the ends upwardly to the discharge opening and, as seen in Fig. 2, the walls incline transversely so that the distribution of the suction stresses will be rendered substantially uniform and the travel of collected substances from the remote art of the base or body portion will be facilitated so as to be as effective as the traveling of substances adjacent the opening. Having thus fully described my invention, what is claimed as new is 1. In a vacuum cleaning tool the combina tion of a base forming a vacuum chamber, a a

socket communicating therewith and connected to the base, and a ball providedwith a handle and an inlet opening mounted'in the socket, said socket having elongated journal bearings, and the ball having journals extending into and rotatable in the bearings and movable along the same, the journals bein eccentric to the axis of the ball for permitting rotary movement of the ball to bring said opening into or out of communication with the base, and an exhaust connection for the ball communicating with the exhaust opening.

2. In a vacuum cleaning tion of a base forming a vacuum chamber and having a discharge or. exhaust opening, a ball and socket connection communicating with sa1d opening, and eccentric journals on one of said parts mounted in curved bearings in the other:

'3. In a vacuum cleaning tool the combi 'nation with a base forming a vacuum chamberand havin a discharge or exhaust opening, of asoc et communicating therewith and having upstanding transversely slotted ears, and a tubular ball havin means of discharge and means'of communication with the exhaust opening, and journals projecting laterally from the ball and disposed eccentric to the axis thereof and extending into the slots of said ears for permitting rotation of.the ball and limiting the extent thereof, said journals being movable. longitudinally of their respective slots.

toolthe combina- In testimony whereof I afiix my signature 4 in presence of two witnesses.
