CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 277,229, dated May 8, 1883 Application filed March 5,1883. (Modem To all whom it may concern: readily adapt themselves to any irregularity Be it known that I, WILLIAM H. CASTLE, that may be in the face of the brush-wheel, of Ashtabula, in the county of Ashtabula and which they could not do were they attached State of Ohio, have invented a certain new to the box on fixed axles in the ordinary way. 55 and Improved Carpet-Sweeper; and I do here- The opposite end of the box is supported on a by declare that the following is a full, clear, small wheel, L, Fig. 5, placed in a recess, (Z. and complete description thereof. made in the end of the box, so that the side of The following is a description of the conthe wheel may be flush therewith, as shown in struction of the carpet-sweeper above referred said Fig. 5. The wheel, being in the recess, is 60 to to, reference being had to the accompanying out of the way of the furniture while sweeping drawings for illustration, and making a part the floor. The wheel revolves on a shaft fixed of this specification, in whichin the hanger M, secured to the end of the box, Figure 1 represents a side View of the sweepas seen inthe drawings. The shaft G of the er. Fig. 2 shows an end view. Figs. 3, 4, and brush revolves on pivotal points eand f, Figs. 6 i5 6 are detached sections.

B and C, Fig. 5, are the dust-pans closing The two wheels 13 and 0 are provided with the bottom of the carpet sweeper or box on I00 rubber tires or bands 0, and for being attached each side of the brush. Said pans are hinged to the end of the box by the bell-cranks they in the ends of the box at the points at and n, p

G, is hinged to the side of the box, and is held and are held tightly closed by the spring D. I Fig. 3 showing an inside view of the end of the box, to which one end of the spring is connected to the end of the pan at n. The pivots m n are so arranged in relation to the pivot of the spring D in the cover that when the pan B is closed the spring, D acts with a constant force to hold it in that position, and when said pan is open the spring-pivot has passed to theother side of the pan-pivot and the spring force there acts to hold the pan open. The broken lines in said figure indicate the position of the pans when open and the relation of the spring thereto. v

E are fin ger-pieces attached to the pans, v whereby they are sprung open to obtain access to the inside for dischargingthe sweeplugs.

F is a socket in which to insert a handle for using the sweeper. The socket, hy the arms in the position shown in the drawings by a spring, H, one end of which is secured to the top of the box, whereas the free end projects forward to and between the arms G. The arms are prevented from falling back upon the side of the box and bruising it bya suitable shoulder immediately in the rear of the said arms, and against which they rest, as seen in the drawings.

Practically the operation of the above-described carpet-sweeper is substantially like carpet-sweepers in ordinary use: it being simply pushed or drawn over the floor, the dust is gathered up by the brush into the box, from which it is discharged in the usual way.

The working of the sweeperis without noise. As the brush is driven by the rubber-banded wheels in frictional contact with the wheel of the brush and the shaft of the brush for being pressed upon endwise by the spring-hanger, there can be no rattling of the shaft in its bearings as they may wear loose in their seats.

No claim is herein made to the spring-hanger and its adjustable bearing, as such will be made the subject-matter of a separate application.

I am aware of the fact that pivoted dustpans are common; also, that a single spring has been connected with both of said-pans, but not to the frame, to hold them in either an open or closed position.

That I claim as my invention, and desire to secure by Letters Patent, is-- 1. In a carpet-sweeper, and in combination with the pivoted pan B, the spring secured at one end to the box and at the other to the pan, and adapted to lock said pan in its closed or open position, substantially as set forth.

2. The slotted hanger M, having a bearing for the axis of the brush-shaft, and av setscrew, jointly with a wheel, L, set in a recess in the casing or end of the box and journaled in said hanger, as and for the purpose setforth.

In testimony whereof I affix my signature in presence of two witnesses.

VVI'LLIAM H. CASTLE.
