To aZZ wiz-0m t may concern.'

Be it known that I, HUGH M. MARSH, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Brooms, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to brooms, mops and the like and more particularly to those in which the parts of the head are permanently secured between a pair of clamping plates having shanks which serve to form a handle socket.

Brooms of the kind referred to are more especially used in shops, warehouses and for other heavy service. For these purposes they are usually purchased in quantities and while great strength is required it is nevertheless desirable that the handle and head should be detachably connected to permit a single handle to be used repeatedly. A detachable connection of the handle and head also reduces the amount of space required for the storage of a quantity of brooms whereby a large number may be more conveniently stored for use in an emergency, `as upon a heavy fall of snow.

The present invention accordingly contemplates an improved construction of the said clamping plates and of the means for connecting them to each other and to the handle.

The object of the invention is to provide a broom or mop of inexpensive, yet efficient construction and of improved appearance.

In the accompanying drawings-Figure 1 is a front elevation of a broom embodying the features of improvement provided by the invention; Fig. 2 is a central longitudinal sectional view of the same, partly in elevation; Fig. 3 is a perspective view of the broom, showing a cover for inclosing the clamping plates; and Fig. 4 is a detail sectional view taken on the line 4 4 of Fig. 1.

In carrying out the invention a pair of mating clamping plates 10, 11, havin positely bowed registering Shanks 12 and 13, are provided. In event the article tobe constructed is a corn broom, these plates are applied with great pressure to 4a bodyof corn strands, as 14, adjacent one end of the same.

Preferably the plates 10 and 11 take the general shape and outline of the inner end portion of a broom head. In order that they may have the required strength while still being formed of relatively light metal, and to insure the corn strands being firmly held between them, each plate is desirably formed with outwardly bowed upper and lower transverse ribs 15, 16, and with a longitudinal rib, as 17, 18, at each side. A still further increased hold of the plates'l() and l1 upon the body 14 of corn ystrands may be obtained by forming the plates with intermediate transverse ribs, as 19 and 20, with the rib, as 19, of one plate bowed outwardly, and the rib, as 20, of the other plate bowed inwardly; also by providing an insta-nding lip, as 21 (Fig- 2), upon the lower edge of each of the plates 10 and 11 at each side of the same. rEhe e'ect of the ribs 19, 20, is to flex the body 14 of corn strands intermediate the lines of engagement therewith of the upper and lower portions of the plates 10 and 11.

For permanently connecting the plates 10 and 11, they are preferably provided with a plurality of intercalating tongues, as 22, and apertures, as 23, adjacent each side. As shown, the tongues 22 are all formed upon the plate 11, the apertures 23 being in the plate 10. l/Vhen the plates are pressed together the tongues 22 are each folded about the adjacent side of the body 14 of corn strands, over the edge of the opposite plate, and are then thrust into the corresponding aperture 23. If. the tongues are made of suilicient length, the curving of the same continues upon entering the corn strands between the plates, and the end of the tongue becomes engaged with the plate 10 upon the inside adjacent the aperture 23, as appears at 24 (Fig. 4).

A permanent rigid connection of the plates 10 and 11 between their side edges is also essential when broom corn is used for the body 14. As shown, such a connection is obtained by mounting a ring 25 about the Shanks 12 and 13 adjacent their inner ends. To prevent displacement of the ring, each of the shanks is desirably depressed, as at 26 (Fig. 2),'at the point where it is engaged by the ring.

The shanks 12 and 13 of the plates 10 and 11 provide a socket for receiving the handle, as 27. A firm, but detachable connection of the handle is conveniently obtained by permanently mounting a pin 28 transversely through the handle, and by providing an aperture, as 29, in each of the shanks 12 and 13 for receiving the ends of the pin. A eompression ring 30 then desirably runs on the Shanks 12 and 13. As shown, the handle 27 has an annular shoulder 31 of greater height than the thickness of the Shanks 12, y13, to Serve as a stop for preventing the compression ring 30 passing upwardly upon the handle beyond the higher ends of the Shanks By making the pin 28 of sul'icient length to project through the Shanks 12 and 13, and by rounding the ends of the pin, the compression ring may be forced upwardly beyond the pin andwill then be held between the pin and the annular shoulder 31. For removing the handle the compression ring 30 must be driven downwardly to pass over the rounded ends of the pin 28. Accidental displacement of thehandle accordingly is effectively preventedln applying the handle 27 to the broom head, the end of the handle is desirably entered between the Shanks 12 and 13 when the compression ring 30 is at the lower ends of the Shanks and` the handle is so turned as to cause the ends oi' the pin 28 to pass into the spaces, as 32 (Fig. 3)-, between the two Shanks. When the shoulder 31 comes into engagement with the ends of the Shanks 12 and 13, the handle will be rotated to bring the pin 28 into alinement with the apertures 29. The compression ring 30 is then driven upwardly over the ends of the pin. The rounding of the ends of the pin 28 enables them to engage the edges of the Shanks 12 and 13 to spread the Shanks and permit the pin to pass under them during the said rotation of the handle. Similarly in withdrawing the handle after the compression ring 30 has been driven downwardly over the ends of the pin 28, the handle is rotated, the ends of the pin thereby separating the Shanks and passing under them until the intervening spaces, as 32, are reached.

The introduction of the end of the handle 27 into the space between the Shanks 12, 13, of the plates 10, 11, is facilitated by providing the handle with a sharp point 37 Fig. 2) Furthermore, to enable the handle to be irmly Seated in that part of the socket which is within the iiXed ring 25, the handle is provided with an annular shoulder 38 adjacent the point 37, that part of the han` dle which is beyond the shoulderbeing of reduced diameter. 1t will be understood that in the construction of the broom head, the space inclosed by the shanks 12 and 13 is freed from projecting ends of corn strands by the use of a drill having a pointV conforming to the point 37 of the handle.

A covering 33 may be applied to the broom head for inclosing the clamping plates 1,0l and 11, if desired. rlhe covering is preferably of Sheet material as cloth or a stiff librous material, which may be shaped to conformto the end of the broom head by heat and pressure. As shown, the cover 33 is apertured at 34 to pass the handle 27 and the Shanks 12, 13, of the plates 10 and 11.

It desired cement may be used in securing the cover 33 to the plates 10 and 11, and as a further securing means a long nail, as 36, may be driven through the cover 33 and into the body 14 of corn strands between the plates 10 and 11 at each side. rEhe cover 33 not only improves the appearance of the plates together intermediate the ends of the plates, a handle fitting the said socket between the shanks, and means detachably connecting thehandle and shanks.
