DUSTER FOR CLEANING WALLS, 860.

SPECIFICATION forming part of Letters Patent N0. 693,100, dated. February 11, 1902.

Application led October 10, 1901.

T0 all whom, it may concern.-

Be it known that I, GERTRUDE M. BELL, a citizen of the United States, residing at Gerinantown,Philadelphia,in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Duster for Cleaning Valls, dro., of which the following is a specication.

This invention relates to a duster or brush for cleaning walls and the like; and the object of the same is to provide a simple and effective device of this character adapted to be adjusted to engage ceilings or walls having different vertical heights, and including a head which is readily separable from the supporting means therefor for the purpose of cleansing or otherwise treating the same.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure l is a sectional elevation of a duster or brush embodying the features of the invention. Fig. 2 is abottoxn plan View of the duster or brush head, showing the support therefor in section. Fig. 3 is atransverse vertical section through the head and showing a part of the support therefor.

The numeral l designates a tubular stock or handle having a lower enlarged grip-terminal 2 and formed with an upper boss 3, having a thumb-screw 4 mounted therein. A` supporting-rod 5 is adjustably mounted in the stock or handle l and adapted to be held by the thumb-screw 4, projected from said stock or handle any distance desired, the upper end` of the supporting-rod being formed with a right-angular flattened arm 6 for a purpose which Will be presently set forth. The duster or brush head comprises a body 7 of suitable material having a covering 8, preferably of sheeps wool,applied over the upper side thereof, around the edges, and under the lower side for ashort distance inwardly from the side edges, so as to fully cover the edges of the body 7 and remove all possibility of the wall orceiling being scraped or otherwise injured and also to better enable thel duster or brush head to be worked into corners orv intersecting angles. In the central portion of the side of the Vbody 7 a 'longitudinallyextending socket 9 is formed, and across a portion of Serial No. 78.249. (No model.)

said socket a clip-plate 10 extends and is rigidly held to provide means for removably receiving the angular iattened arm 6 of the supporting-rod 5 in such manner as to prevent the duster vor brush head from turning. To keep the angular arm 6 in connected relation to the clip-plate l0, a spring-rod ll is employed and has one extremity pivotally connected, as at lla, and the other extremity free and adapted to be sprung over a limiting pin or nail 12, the rod l1 when sprung over said pin or nail closely bearing against the adjacent portion of the supporting-rod 5. When it is desired to release the arm 6 from the clip-plate 10, the rod 1l is pulled inwardly to clear the pin l2 and then turned to one side, as shown in dotted lines in Fig. 2, thus permitting the duster or brush head to be moved longitudinally, so that the arm 6 will come into the portion of the socket 9 unengaged by the clipplate, when the said duster or brush head may be easily separated from the arm4 6. This separation of the duster or brush head from the rod 5 is exceptionally advantageous in reducing the entire device to compact form and also to permit the said head to be cleansed. The fastening means for the arm 6 is simple in its construction and can be easily operated in the mannerrset forth to lock or disengage the duster or brush head. n

When the duster or brush head has been applied in the manner shown by Fig. 1, the rod 5 will be projected from the handle l as far as desired, and the operator will then draw or push the duster or brush head over the Wall to be cleaned, and in view of the adL j ustment of the rod 5 the device will be found exceptionally convenient in cleaning ceiling- Walls, as the operator can stand upon the floor and carry on the cleaning operation without indulging in a tiresome reaching action or being required to stand upon some elevating device. The improved device as an entirety is simple in its construction and can be cheaply manufactured.

Having thus described the invention, what is claimed as new is 1. Inadust-brush, the combination ofasupporting device having an angular end,a brushhead having a socket adapted toreceivesaid angular end, a plate disposed over said socket and adapted to enga-ge said supporting de- IOO vice, and means for clamping said supporting device against said plate.

2. In a dust-brush, the combination of a su pporting-rod having an angular end, a brushhead having a socket adapted to receive said angular end, a clip-plate disposed over said socket and angularend of the supporting-rod, and a locking-rod for clamping the supporting-rod against the edge of said clip-plate.

3. A dust-brush comprising a head having a socket therein, a supporting-rod having an angular end adapted to be inserted in one end of said socket, a plate attached to the outer face of said head over one end of said socket,

a locking-rod pivotally connected to the outer face of said head and adapted to extend trans-` GERTRUDE M. BELL.
