CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 397,204, dated February 5, 1889.

Application filed August 14,1888. Serial No. 282,729. (Model.)

To all whom it' may cm2/cern:

Be it known that we, HIRAM lV. RU TON and HENRY A. GORE, citizens of the United States, residing at Goshen, in the county ot Elkhart and State of Indiana, have invented certain new and useful Improvements in Carpetweepers; and we do declare the follow? ing to be a tull, clear, and exact description ot' the invention, such as` will enable others skilled in the art to which it appertaius to make and use the same.

This invention has relation to improvements in carpetsweepers, and the novelty will be fully understood from. the following description and claims, when taken in connection with the annexed drawings, in which- Figure l is a transverse sectional view of the carpet-sweeper with our improvements applied. Fig. 2 is a perspective view of our improved cam for manipulating the compound levers, and Fig. 3 is a perspective view of one of the levers.

Referring by letter to the said drawings, A indicates a carpet-sweeper case or frame,which may be of any ordinary or approved construction, having the usual attachments for susl taining the brush.

B indicates the driving-wheels, which are journaled on one end of an angular rod, C, which passes through the aperture a in the end walls of the case, and having their opposite ends loosely connected to allow a free movement in any direction with pivoted levers, as will be presently explained.

It should be here observed that the apertures a are sutliciently larg'e to permit of this free movement of the rods or journals C, so that the drivin g-wheels maybe raised and lowered with respect to the case or trame.

D indicates levers, which are pivoted, respectively, to the end walls of the case and at opposite sides of the brush. These levers D, which are preferably of an angular form, have their free ends approximately plain, as at b, to be engaged by a cam or eccentric, as will be presently explained. By this construction it will be seen that by forcing the free ends ot' the levers D apartthe opposite ends will be moved in an opposite direction to each other, ,which will carry with them the rod or journal C, and consequently depress the driving-wheels, which are att-ached to the said rods and in close contact with the brushpulley. This movement will bring the brush up to bear lightly upon the floor or carpet, which is desirable in sweeping lightly. It will be seen that the levers are so arranged that the weight of the sweeper on the iioor will keep the levers, cai, driving-wheels, and brush-pulley in close contact, and by slightly raising or lowering the handle there would be a corresponding movement of the brush. To positively manipulate these levers D, we have provided the device shown in Fig. 2 of the drawings, which we shall denominate the calm and which is designed to cooperate with the bail of the handle in acting upon the 'said levers. In the present illustration we have shown this cam as being separate from the bail and having a central annular recess, e, in 'the outer side to receive the bail; but We do not wish to limit ourselves to this manner of construction, as it is obvious that the ends of the bail may be made in the shape of a cam or eccentric, and pass through the end walls of the case, in which case the said bail end should be adapted to engage the plain faces d of the angular levers D to move them apart. In the construction illustrated this cam E, as we have termed it, is formed so as to rotate in an aperture, F, in the case, and has a flattened or elongated extension on the inner end to come in contact with the upper ends of the levers D, an d when partially rotated will move the said levers so as to distend the drivewheels, and when the elongated portion has been moved in a vertical plane will allow the said free ends of the levers to approach one another and consequently raise the drivingwheels. This cam E is also provided on its outer side with two lateral lugs, e e', which are designed to receive between them the entering portion of the bail, so that the same may be moved in the manipulation of the levers.

lVhile we have illustrated the levers as arranged upon the inside of the case, yet it is obvious that any mechanicy might place them on the outside to serve equally as well and vary the shape of such levers without departing from the spirit of our hivention.

In operation it will be seen that when it is desirable to sweep heavy, so to speak, the handle is raised toward a perpendicular. In

IOO

this posit-ion the d1iving-wl1eels are allowed `to rise with respect to theease as theilree ends ol. the levers are allowed t'o aqiiproaeh each other; but when sweeping lightly l'lie handle is usuallyv lol down in about: the 'position shown in Fig. l ol the drawings, as it` may he grasped hy one hand only. This movement valises the Cam lo come into action,'forcing' the free ends olf the levers apart and throwingl the opposite ends upwardly and outwardly, which, through The `medium ol' the Vrods or journals (l, deprives the wheels and Consequently inereaselhe spare between the hrush and Hoor.

Haring deserihed our invention7 what; we Claim isl. The omnhination, in a eamet-Sweeper, ol levers pivoted tao the end walls of the ease, and having one end Connected with the driving-wheels hy means ol' angular rods or journale', and a @am adapted to engage the oppo site ends ol' the Said levers to move the driving-wheehsj substantially as speeil'ed i. The loomhination, with a sweeper-rase, ol the Cam, Such as 2E, having' a central aperture and lugs, the hamllediail engaging' Said aperture and lugs, and pivoted levers con- .neelied with the journals ol' the driving-wheels and adapted to eng-age the said 0am, \\'l1erel; the drivingwrheels may he moved wit/h rospeet to the ease, Substantially as speeilied.
