Patented Sept. 15, 1931 UNITED STATES EARLE- B. SMITH, OF ALHAMBRA, CALIFORNIA COME AND HOOD. MOUNTING FOR CARPET SWEEPEBS Application filed April 15,

M invention relates to carpet sweepers of the c aracter embodied in my pending application Serial No. 170,213, filed February 23, 1927, in which a hood is mounted in the 6 sweeper body to shield the rotary brush against sweepings jarred from the pans from falling thereon, and combs are associated with the rotary brush for stripping the latter of strings, threads, hair and the like, and to thus mamtain it at all times clean.

It is a purpose of my present invention to provide improved means for mounting the hood in the sweeper body and the combs in stripping relation to the rotary brush, all to the end of reducin the number of parts necessary to the effective mounting of those elements and greatly facilitating the assembly of such parts as well as disassembly in the event of the necessity of renewal of parts.

I will describe only one form of comb and hood mounting for carpet sweepers embodying my invention, and will then point out the novel features thereof in claims.

In the accompanying drawings:

Fig. 1 is a view showing in bottom plan a carpet sweeper having incorporated therein one form of comb and hood mounting embodying my invention.

Fig. 2 is a transverse vertical section view of the carpet sweeper shown in Fig. 1.

Fig. 3 is a fragmentary vertical sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a fragmentary perspective view of one of the combs of the carpet sweeper.

Fig. 5 is a fragmentary perspective View of the hood.

The carpet sweeper in which my invention is incorporated includes the usual body or casing B supported for rolling movementby 40 wheels W, and which wheels operate to drive a rotary brush B through the medium of pulleys P interposed between each pair of wheels W, as best illustrated in Fig. 1. Pans D are secured within the body B so as to be dispo; l substantially at opposite sides of the brushR and to which the sweepings collected by the brush are adapted to be received.

My invention comprises a hood H constructed from a single sheet of metal or other suitable material which is bent so as to be of 1930; Serial No. 444,501.

a-rcuate form in cross-section in order to generally conform to the contour and to cover the brush R when in applied position within the body B. This hood is removably mounted in the body B by the provision of sleeves 15 formed integral with the hood by the bending of suitable extensions of the metal of which the hood is formed. These sleeves are arranged in pairs substantially at the corn- 7 ers of the hood, as best illustrated in Fig. 1, for the sleeves of each pair are longitudinally aligned and spaced by a slot' 16 formed in the hood. Four studs 17 preferably formed of wood are extended, respectively, through each pair of sleeves and into suitable holes 18 formed in the end walls of the body B. Thus with the studs applied to the sleeves and recesses. the hood H is supported at its four corners in fixed position within the sweeper body and so as to overlie the brush R in order that it may serve to protect the brush against the sweepings accumulated in the pans D from being thrown onto the brush when the sweeper body is tilted.

The studs 17 also provide mountings for a pair of combs K employed for stripping the brush R of threads, strings, and-fther fibers in order to 'maintain the brush clean at all times. These'combs are of convent'ional construction except that each is provided at its opposite ends with ears 19 having openings 20 adapted to receive the studs 17, each ear being interposed between the sleeves 15 of each pair and so that the ear is disposed within the corresponding slot 16, all as illustrated in Fig. 3. In this manner the combs are supported for pivotalor swinging movement at the longitudinal edges of the hood and so that they can be moved to stripping or non-stripping position with respect to the bristles of the brush R.

Each ear 19 is provided with a pin 21 which extends too'pposite s des of the ear as shown in Figs. 3 and 4 so as to span the corresponding slot 16 to the end of limiting the inward swinging movement of the respective comb and to thus definitely determine the stripping position of the comb with respect to the bristles of the brush.

It is desirable that each comb be yieldably urged inwardly in order that it may assume a stripping position when the brush R is rotated upwardly in the direct on of the comb, as illustrated in Fig. 2. Conversely, the bristles of the brush serve to move one comb or the other to a non-stripping position according as the brush is rotated in one direction or the other. To urge either comb to stripping position, I provide a pair of springs 22, each of which consists of a length of resilent wire bent in arcuate form and arranged transverselyat' the under side of the hood with its medial portion soldered or otherwise secured to the hood. The ends of each spring bear against the two pins 21 at corresponding ends of the combs K and thus serve to yieldably urge the combs to stripping position.

From the foregoing description taken in conjunction with the accompanying drawings, it will be manifest that my invention provides mountings for the hood and combs of a carpet sweeper which in addition to being of simplified construction greatly facilitat es the assembling and disassembling of the component parts thereof.

Although I have herein shown and described only one form of comb and hood mounting for carpet sweepers embodying my invention, it is to be understood that various changes and modifications may be madeherein without departing from the spirit of the invention and the spirit and scope of the appended claims.

I claim as my invention:

1. A carpet sweeper, comprising a body having arotary brush therein, a hood covering the brush, sleeves on the hood, and studs secured in the body and extending through the sleeves for supporting the hood in covering relation to the brus 2. A carpet sweeper, comprising a body having a rotary brush therein, a hood covering the brush, and co-aeting means on the bodv and hood for detachably securing the hood in the body.

3. A carpet sweeper, comprising a body having recesses therein, a hood having sleeves thereon, and studs extending through the sleeves and into the recesses for detachably gecpring the hood in fixed position within the 4. A carpetsweeper, comprising a body having holes therein, a rotary brush in the body,a hood covering the brush and having sleeves arranged in pairs with sleeves of each pair spaced, studs extending, respectively, through each pair of sleeves and into a corresponding hole for supporting the hood within the body, stripping combs for the brush, ears on the combs positioned, respectively, between the sleeves of each pair and through which the corresponding stud ex tends for pivotally supporting the combs at opposite sides of the brush.

engage the hood for limiting pivotal movement of the combs inwardly of the brush, and

springs are secured to the hood which engage the pins for urging the combs inwardly of v the brush.
