Xga/2023 -cup or insert member which lalso provide important distinct United States Patent 2,771,625 y BRUSH TUFT rAsTENER Francis H. Peloquin, Rockville, Conn. Application April 5, 1954, Serial No. 421,104 3 Claims.v (Cl. '1S- 190) `My invention relates to new and `useful improvements in a brush construction and is directed more particularly to the provision of a novel implement characterized by a is arranged to receive a plurality of bristles and to retain same in a locked position therewithin and which is insertable into an appropriate opening in a backing, holder or the like so as to form a brush.

One of the primary purposes of my invention is to provide structural and operational improvements in devices of the class to which reference has been made, which improvements not only simplify the structure as such but advantages in strength, durability, efciency and the like.

With the above primary objects in view, it is another object of vmy invention to provide a construction of the above described character in which the number of operating parts is greatly reduced and which is compact in accordance with the demands and desires of manufacturers and purchasers alike and which is not only distinctive in its appearance and practical in lits value but also reliable in its operation and eiiicient in its use.

It isa'still further object to provide a device which is constructed of relatively simple parts which are adapted to be readily assembled and which when once assembled are posiitvely and securely retained in operative relationship andwhich cannot be readily andaccidentally separated from each other.

Other prime objects of my invention include: first, the attainment of a higher speed of construction and assembly of the device due to its simplification of design and its unique composition of parts; second, the provision of an improved brush construction which may be made more economically and with fewer operations in the manufacture of its parts, as well as in the assembly of the same, than prior devices known in the art; and third, the provision of such other improvements in and relating to brushes of the type above referred to as are hereinafter described and claimed.

All of the above objects I accomplish by means of such structure and relative arrangements of parts thereof, as will fully appear by a perusal of the description below and by various specific features which will be hereinafter set forth.

To the above cited and other ends and with the foregoing and various other novel features and advantages and other objects of my invention as will become more readily apparent as the description proceeds, by invention consists in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more particularly pointed out in the claims hereunto annexed and more fully described and referred to in connection with the accompanying drawings where- 1n:

Fig. 1 is a top plan view of the lock ring of the invention;

Fig. 2 is an end elevational view of the lock ring shown in Fig. 1;

Fig. 3 is a side elevatonalview of the cup. insert of the invention with parts broken away for the sake of clarity;

Fig. 4 is an end elevational view of the cup insert shown in Fig. 3; v

Fig. 5 is a side elevational view of the cup insertiin combination with bristles forming the `brush insert of the invention; and

Fig. 6 is an end elevational View of the cup insert and bristles shown in Fig. 5. v

In the accompanying drawing, I have illustrated a cornplete example of a physical embodiment of the invention in which the parts vare combined and arranged in acocrdance with one mode which I have devised for the practical application of the principles of the invention.

It will, however, be understood that changes and alterations are contemplated and may be made in these exemplifying drawings and mechanical structures, within the scope of the claims, without departing from the principles of the invention.

In the following description and claims, various details will be identified by speciiic names for convenience. These names, however, are intended to be as generic in their application as the art will permit.

Referring now to the drawing more in detail, in which similar characters of reference indicate corresponding parts in the several figures and referring more particularly to the preferred form of my invention selected for illustrative purposes, I have shown a lock ring generally indicated by the numeral 10 which comprises a transverse cross-center beam portion 12 and yieldable semi-circular side arm portions 14 and 14 attached to opposite 'ends thereof. The opposite

free ends

16 and 16 of the side arm portions 14 and 14 are lcompressible towards the transverse beam portion 12 so as to make contact therewith thereby closing the locking ring and providing a pair of closed openings.

Tuft material 20 such aselongated bristles or the like may be doubled over the transverse beam portion 12 and inside of the side arm portions 14 and 14 and by cornpressing the members 14 and 14 thereagainst the tuft material may be locked within the loclt ring.

A cir-cular cup insert generally indicated by 30 is provided having a rounded upper or top portion 32 and an open lower or bottom portion 34 terminating in an outwardly extending ange on all sides of the cup insert.

The cup insert is of a dimension so as to receive the lock ring therein in a press slip manner shortly to be described.

On opposite sides of the cup insert pairs of oppositely spaced lugs are provided including on each side an upper lug 40 and a lower lug 42. The upper lugs 40 are upset inwardly by means of staking tools or the like.

In the early formative stage, and lower lug 42 consists only of a slit 41 as shown in Figs. 3 and 4.

Thereafter the lock ring 10 is inserted within the insert cup until the upper side of the transverse beam portion 12 abuts lower ends of the upper lugs 40 and 40. The lugs function as anchors and the side arm portions14 and 14 expand outwardly against the interior wall of the member 30 and are embraced thereby.

The lower lugs 42 and 42 are then upset inwardly after the insertion of the lock ring into the cup insert thereby locking the lock ring therewithin.

At the opposite ends of the cup insert 30, an outwardly extending upset or prong 50 is provided in each side wall for purposes shortly to be observed.

The cup inserts, when tufted as above described, are pressed through holes or openings in lany desired type of holder or backing member whereby a brush is formed.

The top side of the iiange acts as a stop against the entrance of the hole or opening in the holder or backing rnember'and thel prongs '50 act asV locks-on the'opposite sides of the cup so as to retain said cup insert within the opening.

The' inner wall of the` insertischarnferred as attr-35, as shownin Figs. 3 andl 4 whereby the bristles 20` are protected against roughened or sharp edges whereby any 'undesired cutting action is obviated.

v The invention may be embodied in other specic forms without departing 'from Ithe essential characteristics-thereof. Hence, the present embodiments `are therefore to be considered in all respects merely as being illustrative and not as beingrrestrictive, the-.scoper'o'f the.l invention being indicated by the appended claims. rather than by the Yforegoing description, andv allemodications and variations asffallwithin the meaning andpnrview and range of equivalency of the appendedl claimsv are therefore in- -tended tobe embraced: therein.
