WILLIAM MONROE OLEAVELAND, OF HIGHLANDS, NORTH CAROLINA.

PACKAGE-FASTENER.

Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed February 11, 1908. Serial No. 415,297.

To all whom it may concern.'

Be it known that I, WILLIAM M. @LEAVE- LAND, a citizen of the United States, and a resident of Highlands, in the county of Macon and State of North Carolina, have in vented a new and Improved PackageFas tener, of which the following is a full, clear, and exact description.

The urpose of the invention is to provide novel t etails of construction for a fastening device, which adapt it for. very convenient and reliable service, as a means for releasably securing a cord or band in wrapped condition upon a package of mail matter or other material it is desirable to temporarily secure, in a manner which will permit the package or bundle to be quickly opened and re-fastened, if this is desired.

The invention consists in the novel construction and combination-of parts, as is hereinafter described and defined in the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the improved fastening device, applied for securing a band in taut condition wrapped around a package;` Fig. 2 is an enlarged longitudinal sectional view of the fastener, substantially on the line 2 2 in Fig. 5, showing parts adjusted for releasing a band shown in part, Fig. 3 is a longitudinal sectional view of the fastener, showlng parts adjusted for securing a band when drawn in taut condition, por tions of the band appearing as connected with the device; Fig. 4 is a sectional side view of the improved fastener, working details thereof appearing as partially adjusted for releasing a tie band, the latter being shown as engaged with the fastener, and Fig. 5 is a plan view of the improved package fastener.

The body portion of the improved fastener is essentially U-shaped in cross section, consisting of a flat bottom wall l() of a suitable width and length, upon which are .integr-all y formed two parallel side walls 10, the upper corners on which are preferably rendered convex. At one end, on one side wall 10, a clamping jaw 10b is formed or secured, that is of less width, vertically considered, than the side walls 10a, and an end portion l()C of said jaw projects laterally beyond both of said walls, and has an ovate form edgewise,

which adapts said end ortion 10" to serve as a guide finger, as wil hereinafter be more fully explained.

The bottom wall 1() is removed to a short extent below and near the transverse clamping jaw 10b, providing a throat-opening a., and above said opening between the side walls 10a a clamping block 11 is pivoted as at l). The block 11 fits loosely between the walls 10- and has a convexed lower edge, which extends from one end to a point adj acent to the upper edge at the other end of the block, which latter end is in service disposed adjacent to the clamping aw 10b. The periphery of the clamping block 1l in the portion nearest to the transverse jaw 10b is serrated transversely, as shown at c, and the pivot b, which supports the clamping block i l, is disposed eccentric to the convexed edge having the serrations c. A short finger d is formed on the clam )ing block 11 adjacent to the serrations c, amf in service projects above the upper edge of the jaw 10b. The serrated edge portion c of the clamping block 11, closely approaches the side of the jaw 10b, but does not contact therewith when the clamping block is so adjusted that the finger d is disposed near to the upper edge of the clam ing aw, as is shown in Figs. 3 and 4.

A ocking lever l2 is an essential detail of the invention, and as shown, is in the form of a flat plate-like lever of a suitable length, and a width which permits it to work freely between the side walls l()a of the body 10, when arranged for service. Upon the lower side and at one end of the lever 12 two flanges e, e are formed, which are spaced apart so as to leave a channel between them. The flanges e are preferably rounded on their edges, and concentric with said edges they are transversely perforated for the reception of a pivot g, which also passes through opposite perforations in the side walls of the body 10.

The upper rear corner of the clamping block 11 is reduced in thickness by an equal removal of material at the sides, thus producing a toe h on the block, which may be loosely inserted between the flanges e. The edge portions of the flanges e, e that are near to the transverse edge e', of the lever body 12, are concaved slightly so as to permit the edge e to interlock with the adjacent porblock and the rear side of the jaw 10b.

A coiled spring 14 is held in position between thef'bottom wall 10 and the lever body 12, by short pins formed on opposite ends of said spring, whereby the normal expansion of the latter is adapted for enforcing an engagement of the locking lever with the rear portion of the clamping block 11.

A flexible tie string or band 15 is employed for wrapping upon a parcel or package, and one end of said band is secured upon the end of the body plate 10 that is furthest from the jaw 10b, in a perforation therein, leaving a suflicient portion for its designated purpose as a tie band.

In application of the complete fastening means upon a package A, the band 15 is passed around said package longitudinally and laterally and drawn tautso as to properly bind the articles composing the package together. The fastening device is in this way disposed upon one side of the package longitudinally thereof, as shown in Fig. 1, and in position for its service as a securing means. The free end of the band 15 is now drawn taut and passed around the end of the guide finger 10 c, which will conduct the band into the opening a and into Contact with the side of the jaw 10b. To facilitate the insertion of the band 15, as described, the clamping block 11 should be adjusted so as to separate the serrated edge c from the jaw 10b, as is represented in Fig. 2; then when the band is properly drawn upon the package, the lever 12 is depressed at its rear end, as shown in Fig. 4, which will release the forward end of said lever from the block 11. Simultaneously with the rocked adjustment of the lever 12 which compresses the spring 14, the finger CZ is manually depressed, which will rock the serrated edge of the clamping block into forcible engagement with the band 15, this being produced by the eccentric formation and pivotal engagement of the block with the side walls 10a.

It will be seen in Fig. 3, where the locked adjustment of the fastener is shown, that the lever 12 is rocked into a level position by the tension of the spring 14, the finger d is pressed upon the band and co-acts with the serrations c for holding said band from slipping, and that the forward transverse edge of the lever body 12 is impinged upon the toe h, thus locking the clamping block in clamped adjustment, which can only be released by a depression of the free rear end of the lever as shown in Fig. 4, and hereinbefore eX lained.

t will be noted that the application of the fastener may be very quickly effected, that pulling on the free end of the band will not release it, that strain on the wrapped ortion of the band will serve to cause the b ock or dog 11 to increase its bite upon the band, and that only the manual depression of the lever will release the band, which when desired may be instantly effected.

As the upper surface of the lever 12 and the top edges of the side Walls 101L are substantially level with each other, an accidental depression of the lever is not liable to occur, so that a package or bundle fastened by application of the improvement upon a tie band Will remain intact until the same is released by manipulation.

The improvement is preferably constructed of a suitable metal that with exception of the spring 14 may be cast into form, and in quantity may be produced cheaply, and as the device may be re-used many times, it will save time by its employment, and also the cost of Wrapping twine commonly used for tying parcels of various kinds.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A package fastener, comprising a band or the like, a body to one end of which one end of the band is secured, said body being provided 'with a xed jaw at the end opposite that to which the band is secured and with an opening adjacent to the aw for the passage of the free end of the band, a clamping block pivoted eccentrically in the body and adapted to clamp the band onto the fixed jaw, said block being provided with a finger projecting over the Xed jaw when the block is in clamping position, and means for engaging the clamping block to hold it in closed or open position.
