WARREN M. CONRAD, OF CHELSEA, MASSACHUSETTS.

PACKAGE-FASTENING IVEEMBER.

' Specification of Letters Patent.

Patented Aug. 17, 1909.

Application filed June 15, 1908. Serial No. v438,505.

T0 all 'whom it may concern: a

Be it knownthat I, WARREN M. CONRAD,

of Chelsea, in the county of Suffolk and'State of Massachusetts, have invented certain new and useful Improvements in Package-Fastening Members, of which the following is a This invention relates to a metallic member adapted to engage portions of a wrapping cord or strmg, and hold the latter in cone fining engagement with a parcel or package.-

The invention has for its object to provide a simple and effective fastening member of this character adapted to securely grip the string at a plurality of points, and in such manner as to securely hold the string and prevent the slipping of the same without fraying or cutting the string, and therefore without weakening it. i

. The invention consists in the improved fastening member which I will now proceed to describe and claim.

Of the accompanying drawings forming a part of this specification, Figure 1 represents a plan view showing a parcel confined by a string, and a string-engaging member, embodying my invention. Fig. 2 represents an enlarged section on line 22of Fig. 1. Fig. 3 represents a section on line 33 of Fig. 2. Fig. 4 represents a plan view of the blank from which the fastening'member, shown in Fig 1,is made. I

he same reference characters indicate the same parts in all the figures.

My improved fastening member is composed of a substantially flat plate 12, preferably of sheet metal of sufficient thickness to afford the requisite stiffness. Portions of the margin of the plate are extended to form cars 13, which, in the blank shown in Fig. 4, radiate from the center of the plate, and are adapted to be bent over the body of the plate and overhang considerable portions of said body, as shown in Figs. 1 and 2.

The inner side of each ear and the adjacent side of the portion of the plate overhung by the ear, constitute string-gripping jaws which are separated by a contracted tapering throat opening inwardly toward the center of the plate. In other words, the months or open ends of the throats are nearest the center of .....the plate so that the strain exerted on the stretches of string 14 engaged by said jaws tends to pull the engaged portions of the string toward the closed ends of the said throats. The said jaws are more widely separated at the mouths of the throats than at the closed ends, the jaws convergin from the mouths of the throats so that the t roats are tapered, as shown in Fig. 2. Each car 13 is provided with a longitudinal boss 15, which projects fromthe inner side of the ear toward the corresponding portion of the plate, and extends lengthwise of the ear, and

in this embodiment of my invention, from ts the neck portion of the ear toward the center of the plate. The portions of the plate which are overhung by the-ears are provided with corresponding bosses 16, which project outwardly from the plate toward the cars,

and coincide with the bosses 15, each boss 15 and the corresponding boss 16 forming the acting portions of a pair of string-gripping jaws, said acting portions being of considerablyless width than the-ears, as indicated in- '15 Figs. 1 and 3, so that they are adaptedjto. indent, and therefore firmly grip the portion of string that is inserted between the jaws.

By reference to Fig.14, which shows the blank from which the fastening member is made, it will be seen that the bosses 15 and 16 are formed before the ears are bent over the body of the late, the bosses 15 being in alinement with t e bosses 16, and separated from the latter by portions 17 of the blank, I

which portions are practically'flat in cross section, and are, therefore, adapted to be bent to form the necks which connect the ears with the body of the plate, the flat form of the portionsl? enabling the said ortions to be as abru tly bent, as-to bring t e inner ends of the osses into close proximity to each other.

Fig. 1 shows a suitable engagement between the fastening member and a string 14 which embraces a arcel or ackage 20, one end of the string eing re erably engaged with one of the pairs of aws before the application of the fastening member and string to the package. then laid flat upon one side of the ackage and the string is carried in onelirection' around the package between another pair of j awe, then around the package in a direction at right angles with the first wrapping,' and then enga ed with the third pair of jaws.

find that the bite or grip exerted on the string by the bosses 1 5 and 1 6 enables the string to be securely held against longitudinal movement by being passed once between the jaws of each pair, although if desired, the string may be passed between each pair of iasrsonore The fastening member is 00 thanonce, thejaws being sufficiently elongated to permit of this. The opposed bosses are free fromsharp angles or corners liable to out or fray the string, so that the latter is I string tions.

plate so that when the device is in use the pair of jaws portion of a length of string while the other securely held without liability of being weakened at the points where it is gripped, Either edge of either ear 13 may be utilized for severing from the main body of string the portion that has been engaged with the arcel and the fastening member, the thin e ges of the. ears constituting somewhat blunt cutters on Which the string maybe severed by pulling it forcibly against one of said edges.

The distance between the string-gripping p jaws formed by the bosses, and the edges, 0

the ears is such that the severance of the across one of said edges does not two pairs are adapted to grasp the end por- All the jaws are at one side of the plate is entirely under all the portions of the 'strin which are en a ed with it and no points,

parts of. the string are inter osed between the plate and the package. 7 he fastener is therefore adapted to be quickly engaged with the string .by lateral movement of the string into the throats, no threading of the string through openings in the platebeing required. The employment of a 'sufiicient numberof jaws to gras the string at three vim-its centre and two end portions, enables the operator to engage the central portion of the string with the fastener l by forcing it laterally between'the jaws of one pair before applying the fastener to the ackage, the en portions being subsequently engaged with the other jaws.

I claim:

A'pa'ekage fastening member formed from p a flat sheet metal'plate having an approximately triangular ody ortion and ears at the angles, said ears an A body portion having bosses in alinement but separated by intermediate fiat. neck portions which are bent to cause the ears to overhang the body of the plate, the ear bosses cooperating with the body bosses in formin string-gripping jaws which are separator by contracted spaces or throats opening inwardly toward the center of the plate.

In testimony whereof I have aflixed my signature, in presence of two witnesses.
