Application May 9, 1931, Serial No. 536,190 Renewed September 19, 1933 2 Claims.

This invention relates to adapters for, and to brooms, mops and other implements.

One object of this invention is to provide an improved adapter or clamping means for simultaneously engaging a handle and an implement head.

Another object of the invention is the provision of improved unitary means for securing together parts of an implement.

Another object is to provide an implement head with improved means whereby the same may be engaged by a clamping device.

Another object of the invention is the provision of a clamp and an implement head in improved l5 combination and arrangement with each other.

A further object of the invention is to provide a device of the nature set forth having few and simple parts, and which is inexpensive to manufacture and assemble, rugged, durable, reliable,

2O convenient and efiicient in use. 7

Other objects and advantages of the invention will become apparent as the specification proceeds.

With the aforesaid objects in View, the invention consists in the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated on the annexed drawing, wherein like parts are designated by the same reference characters throughout the several views.

In the drawing:

Figure 1 is a View in front elevation of an adapter embodying the invention.

Fig. 2 is a side edge view thereof.

Fig. 3 is a fragmentary View in elevation of an implement head.

Fig. 4 is a sectional view taken on line 4-4 of Fig. 1 and showing the implement head secured therein in corresponding cross section.

The advantages of the invention as here outlined are best realized when all of its features and intrumentalities are combined in one and the same structure, but, useful devices may be produced embodying less than the whole.

It will be obvious to those skilled in the art to which this invention appertains, that the same may be incorporated in several different constructions. The accompanying drawing, therefore, is submitted merely as showing the preferred exemplification of the invention.

Referring in detail to the drawing, 10 denotes a device embodying the invention. The same includes an implement head consisting of two substantially similar members of sections 11 and 12.

' These may co-operate to form a skeletonized tubular shank portion 13. The member may be provided with portions such as lugs 14 extending into overlapping relation toward each other, and being suitably movably interconnected as by alined pivot pins or rivets 16, whereby the members are adapted to swing in the manner of the jaws of a clamp.

In order to secure a handle to the adapter, the latter is provided with any suitable fastening or holding means so arranged as to engage the handle or other device upon moving the members 11, 12 toward each other. For instance, each of said members may have, at the shank portion 13, an inward extending ridge 17 which may in this case, be provided by pressing the metal oppositely inward at 18. But ordinary frictional engagement may also be used.

In order to permit the adapter to be opened while a handle or bar, as of wood, or any other material, is extended into the shank 13, the upper ends of the members 11, 12 are preferably cut away or otherwise arranged for clearance as at 19. This affords substantial room for pivotal movement of the members relative to such bar or handle. In fact, the nature of the shank at the recesses 19 is such as to afford an entrance for easy insertion of a bar into the shank, the bar entering between the members 11 and 12 and the lugs 14 thereof, it being noted that when the adapter is in open position, the size of the opening across the recesses 19 is greater than the diameter of the opening between the opposite lugs.

The members 11 and 12 terminate in lower holder portions 20, 21, respectively, which may be of substantially plane, or any other shape, and extend at an angle to the axis of the adapter. The extreme lower edges of the holder portion may be inwardly lipped at 22, if desired. Between the holder portions may be inserted a mop, broom, or other implement head, and suitable means may be provided for closing the adapter so as to cause a simultaneous engagement of the handle by the fastening means 18, and an engagement of the implement head between the holder portion 20, 21. One form of said means will now be described. a

It may be found convenient for certain purposes to have a tension element, such as a bolt 23 extended through such part of the members 11, 12 as to be directly engageable with the implement head. Therefore, a screw member 23 may be passed through an opening 24 in the portion 20, or otherwise engaged therewith, preferably nonrotatably, as by providing a narrow flattened portion or groove 25 in the bolt, and lugs 26 in the opening which may be struck into said groove. This affords a quick means of assembling, and the head 27 of the bolt is external to afford proper bearing on the member 20, and to afford a hold for a wrench, if that should for any reason be necessary.

On the holder portion 21 may be provided an engagement means for coacting in tension with the element 23, such as a wing nut 28 which may be alined for threaded engagement with the bolt. In order to preferably permanently swivel the wing nut to the portion 21, the wing nut may be passed through an opening 29, and headed over at 30 to provide a flanged bearing whereby the wing nut is rotatably secured to the portion 21.

Additional fastening means may be provided, if desired, such as alined inward extending lugs 31 suitably arranged, as on opposite sides of the bolt axis, and any means may be used which engages an implement head upon closing the adapter. The lugs 31 may be formed by stamping inward as shown.

The device as thus far described may be made of any suitable material, preferably metal, and can be constructed by casting, molding, or stamping, the latter lending itself best to commercial production.

For illustration, a mop head is shown at 32, the same including a plurality of strings, or fibers 23 bound together by a strip 34 of strong flexible material, such as canvas, which may be secured thereto, for example, by stitching at 35. As thus far described, the construction is intended to be conventional and representative of a large class of implements. As an anchoring means, members 31 having openings therein, and which may be in the nature of eyelets, are provided secured only to the material 34, and not passing through the head. There are thus a plurality of alined eyelets at each side of the head.

Intermediate of the eyelets is provided an anchorage such as a tube 37 which may extend wholly through the head, and headed over at 38. This tube may be shorter or longer, and may serve as a spacer as shown.

In assembling the device, the implement head is inserted between the jaws of the adapter so that the bolt 23 is passed through the opening in the tube 37. When the adapter is closed, the wing nut 28 comes into alinement with the bolt and may be tightened in engagement therewith. The lugs 31 enter the eyelets and strongly engage the same so that the implement head is reliably con- Jill nected in place. Simultaneously, the handle will have been connected with the adapter as hereinbefore described. It will be understood that, as regards the holding of the implement head, either the bolt, or the lugs, or both, may be used, except that some means must be provided to draw together the adapter jaws. Ordinary frictional engagement may also be used for the implement head.

It will be appreciated that other types of implement heads may also be secured by an adapter of this kind.

It will be appreciated that various changes and modifications may be made in the device as shown in the drawing, and that the same is submitted in an illustrative and not in a limiting sense, the scope of the invention being defined in the following claims.

We claim:

1. In combination, an adapter clamp having a plurality of elongated jaws, each of said jaws having a central upwardly extending integral shank, said shanks being curved in cross section toward each other for receiving and gripping a handle, said shanks being pivotally interconnected at opposite sides of the handle at an end of the shanks remote from said jaws, the latter having a central interconnecting tension element permanently connected to one jaw and detachably associated with the otherjaw, said jaws having projections extending toward each other on opposite sides of the tension element, and a flexible implement head having a permanent central tubular member therein through which said tension element extends, said member constituting a spacer between the jaws, and said implement head having reenforced recesses in the wall thereof in which said projections are removably engaged.

2. In combination, an adapter clamp having a plurality of jaws movable toward and away from each other, and a flexible implement head having a tubular member extending therethrough and reenforced recesses spaced from said member, said jaws having projections engageable in said recesses, and a tension element extending through said jaws and the tubular member to draw the jaws together, with the tubular member constituting a spacer between said jaws.
