Patented Jan. 13, 1942 CARPET SWEEPER Carl C. Parrish, Shelbyville, Ind., assignor to Porter Steel Specialties, Shelbyville, Ind., a copartnership composed of Hester Porter Fuller, George M. Parker, and Parrish Fuller Application May 1941, Serial No. 391,851

2 Claims.

The object of my invention is to provide efficient means by which dust pans of a carpet sweeper of the rotary-brush, hand-operated type may be readily operated to discharge their contents, the construction being such that the exposed operating element, though readily accessible, will be inconspicuous and cannot be contacted against furniture, and such that it can be incorporated in a sweeper at low cost.

The application is a continuation, in part, of my application Serial No. 317,650, filed February 7, 1940.

The accompanying drawings illustrate my invention.

Fig. 1 is a perspective view of an embodiment of my invention;

Fig. 2 an end elevation with one of the external cover plates removed;

Fig. 3 a fragmentary plan in partial horizontal section;

Fig. 4 a transverse section on line 44 of Fig. 1 with the pan shown in dumped position;

Fig. 5 a fragmentary section on line 55 of Fig. 4;

Fig. 6 a perspective view of another embodiment of my invention;

Fig. 7 an end elevation (with one end plate removed) of the form shown in Fig. 6;

Fig. 8 a section in the plane of line 8-3 of Fig. 6; and

Fig. 9 a fragmentary horizontal section of the form shown in Fig. 6.

In Figs. 1 to 5 of the drawings l0 indicates the usual end wall of the main casing or shell of a sweeper. Formed in the outer vertical face of this end wall is a groove II which communicates at its outer end with a slot or groove l2 formed in the upper face o f the top wall l3 of the easing parallel with the side wall [4 of the casing.

Where the top wall of the casing is of wood, the slot or groove l2 conveniently extends through the top wall and is covered by an ornamental plate I6 medially depressed to form a channel II, the outer end of which communicates with groove l l and th inner end of which is formed into a thumb pocket l8. Journalled in groove I l is a rock shaft provided at its outer end with an operating arm 2| adapted to lie in channel I! when the rock shaft is in its normal position. The free end of arm 2| is conveniently widened to partially fill the thumb pocket but of such size that an operator may readily insert a thumb or finger into the pocket underthe free end of the arm so as to readily raise it.

an arm 25 projected inwardly through perforation 26 in the end wall at the inner end of groove H and adapted to engage under the apex of the pan spring 2'6 of usual form, the free ends of said pan spring pivotally engaging the heels of the dust pans 2l2'| in an ordinary manner. The dust pans are pivotally mounted between the end walls of the casing on pivots 2828.

Rock shaft 20 is held in groove H by suitable retaining strips 29 or double pointed tacks 30.

The operating arm 2| of rock shaft 20 is so formed that, when in its normal pan closed position, it will lie flush with the upper surface of the top wall of the casing.

The construction described is such that it may be manufactured at very low cost and the operating arm, under normal working conditions, is so positioned that it cannot come into contact with any furniture.

In the form shown in Figs. 6 to 9 inclusive, the construction is very much the same and corresponding parts are designated by the same reference numerals. In this form groove II is continued, at its outer end, through the side wall l0 and the operating arm 2! of rock shaft 20 normally lies alongside said side wall immediately above the usual bumper band or guard rubber 40.

It will be readily understood that while I have illustrated embodiments of my invention in a sweeper having end walls of appreciable thickness, such, for instance, as plywood commonly used in the art, a metal end wall in which an appropriate receiving groove for the rock shaft may be formed by distortion of the metal, would be within the scope of my invention.

The operating arm may be of quite appreciable length so that pan dumping will require the exertion of very little force so that it may be readily manipulated by the most delicate fingers.

I claim as my invention:

1. A carpet sweeper having a casing comprising end walls, side walls, and a connecting top, with one end wall provided with a groove formed in the outer face of said end wall and extending from about the medial plane of the casing outwardly toward a side wall, a channel formed in the upper surface of the top wall of the casing substantially at right angles to said groove and communicating at its outer end with said groove, a rock shaft journaled in said groove and provided, at its inner end, with an inwardly projecting arm extending through the end wall of the The inner nd of rock shaft 20 is provided with casing and provided at its outer end with an operating arm nestable in said channel in the upper face of the top of the casing, means retaining said rock shaft in said groove, dust pans movably mounted in the casing, and means connecting the said inwardly projected arm of the rock shaft with said dust pans, said parts being so related that the operating arm will be submerged in the channel when the pans are in dust-receiving positions.

2. A carpet sweeper having a casing comprising, end walls, side walls, and a connecting top cal with one end wall having a groove formed in the l and provided at its inner end. with an inwardly projecting arm extending through the end wall of the casing and provided at its outer end with a manually-accessible manipulating arm, means retaining said rock shaft in said groove, dust pans movably mounted in the casing, and means connecting said inwardly projected arm of the rock shaft with the dust pans, the two arms of the rock shaft being so related that, when the pans are in dust-receiving positions, the manipulating arm will lie at least as low as the exposed face of the top of the casing with its free end directed toward the opposite end wall.
