KUivrrn TATES GEORGE S. SANFORD, OF MOUNT OLEMENS, MICHIGAN.

CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 481,829, dated August 30, 1892.

" Application and November 9,1891. sean No. 411,376. (No modem To all whom it may concern,.-

.Be it known that I, GEORGE S. SANFORD, a citizen of the United States, residing at Mount Clemens, county of Macomb,State of Michigan, have invented a certain new and useful Improvement in Carpet-Sweepers; and I declare Jthe following to be a full, clear, and exact descripion of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to carpet-sweepers of the class shown by my several applications filed herewith, to wit: Serial Nos. 411,37 3 and 411,375, iled November 9, 1891, in the former of which I have shown and claimed, broadly, the combination of various means for opening and closing the dust-panwith a rod or cable permanently connected therewith and operating longitudinally with the handle of the sweeper. In this application I desire to cover certain special forms embodying this principle.

In the drawings, Figure lis a sectional view showingthe employment of levers in conj unct1on with a plunger provided with a coilspring. Fig. 2 is a sectional view showing a vertical plunger and a system of levers, one provided with a tooth-segment engagingwth a rock-arm on the side of the plunger. Fig. 3 is a sectional view of a construction similar to that shownin Fig. 1 in which the leveris engaged indirectly with the plunger. Fig. 4 is a view in which the levers employed are on the outside of the case and the plunger or link extending up through the case and engaged with a coil-spring on the outside. Fig. 5 isa cross-sectional view of the interior of a sweeper constructed according to the formV yof one of the rods with the pan being omitted for clearness.

In the drawings, A is the frame or case of the sweeper.

A is the dust-pan.

B is a rock-shaft located longitudinally in the case and rigidly attached thereto, and close to the inner end of the case is a rockarm B.

B2 isa rock-arm attached to the rock-shaft in the center and extending inward underneath the opening or in the top of the case, and to the inner end of which is attached a cable C.

D is a vertical rod moving up and down in suitable guides and provided with a spring d, adapted to force the rod to the extreme upper end of its movement. The rod D is pivoted at the lower end to the dust-pan A The action of the spring is to hold the dust-pan in its closed position, and when the cable C is drawn upward by elevating the rock-arm B2 and depressing the rock-arm B the rodD is depressed and the dust-pan is forced open.

In Fig. 2 the vertical rod or bar is provided with any suitable guide, such as pin d, engaging with the slot d2 in ihe bar or rod, and is provided with a rack d3, in which is engaged the segment e on the end of the lever E. This lever is connected with the rock-arm B by the link b.

In Fig. 3 the construction is similar to that shown in Fig. 1, but employs a connectinglink F between the vertical rod D2 and the rock-arm B.

In Figs. t and 5 the construction is varied from that shown in Figs. 1, 2, and 3 in the employment on top ofthe sweeper of a straightlever G, pivotcd to a standard g on the top of the case A, and in which the vertical rod or link D3 is bent or set off to carry its lower end to the side of the sweeper to pivot it to the dust-pan, and is provided above the oase with a coil-spring adapted to draw the rod upward and close the dust-pan. In this case the cable or rod C is engaged directly with the levers outside of the case instead of passing down through the top of the case through the opening a.

It is to be understood that in each oE these variations the construction may be duplicated to provide for opening and closing two dustpans, and two cables or rods running lengthwise of the handle maybe employed, each connected with a lever either inside or out- IOO in Fig. 4,pvoted o1' engaged with two Vertical the spring, and means connected with said rods or standards on the same end of the case rock-arm and extending up the handle and and adapted to open both dust-pans. movable longitudinally therewith for operatlVhat I claim is ing the saine, substantially as described. 5 In a carpetsweeper, mechanism for dump- 1n testimony whereof I sign this specificzii 5 ing the dust-pan, consisting of a vertical rod tion in the presence of two witnesses. pivoted at its lower end to said dust-pan, a GEORGE S.
