SACK FASTENER.

EDGAR G. FAWCETT AND ANDREW McKILLOP, OF LAKE CITY, COLORADO.
SACK-FASTENER.
T 0 all whom it may concern:
Be it known that we, EDGAR O. FAWOETT and ANDREW MCKILLoP, citizens of the United States, and residents of Lake City, in the county of Hinsdale and State of U010- rado, have invented certain new and useful Improvements in Sack-Fasteners, of which the following is a specification.
Our invention is an improvement in sack fasteners and consists in certain novel construction and combination of parts hereinafter described and claimed.
Referring to the drawing forming a part hereof Figure 1 is a perspective view of the upper part of a sack provided with our improvement showing the fastener closed. Fig. 2 is a perspective view of the fastener frame open. Fig. 3 is a section on the line 33 of Fig. 1 showing the sack closed, and Fig. 4 is a section on substantially the same line showing the sack open.
In the present embodiment of our invention, the fastener comprises a frame composed of sections A, B, the ends of each of the sections being bent at an angle to the body portion as at. O, and provided with a closed loop D,-the loops at the corresponding ends of the sections being arranged in alinement and traversed by a rivet E, wherebody portion at thls polnt.
by to secure the sections in hinged relation with respect to each other. The section A is provided near each end with a species of hook G, the hook being bent from the body portion of the section, and the section B is provided at corresponding points with a catch H. also bent from the body portion of the section. The hook G is formed by bending the body portion of the section into an open loop whose arms 9 are at right angles to the body portion, thence returned upon itself as at g, inwardly as at 9 and again returned upon itself as at The catch H is formed by bending the section to form an open loop whose arms h are at right angles to the body portion, the arms of the loop being returned upon themselves as at h, thence bent outwardly as at 71 and backwardly as at 7L3.
It will be observed that the angular portions O of the section A are longer than the angular portions of the section B, so that when the sections of the frame are closed, the section A will overlap the section B, the hook of the section A passing between the Specification of Letters Patent.

arms of the catch on the section B, and engaging the cross bar If off-set laterally and upwardly from the body portion of the section, the peculiar bending of the arms con necting the cross bar with the body portion, being to permit a springing of the cross bar when engaging and disengaging the hook. The hook is in its simplest form merely a hook, the peculiar bending being for the purpose of permitting some yielding of the hook during engagel'nent and disengagement. The fastener is especially adapted for bags containing granular or pulverulent materials, and it will be evident that the bag being filled, the strain on the sides of the bag will tend to move the sections of the fastener outward, and since they overlap, this outward movement will be toward each other, thus moving the hooks into closer engagement with the cross bars.
The loops on the ends of the angular section of the section B are arranged inside of the loops on the angular ends of the section A, thus permitting the body portion of the section B to move beyond the body member of the section A when the bag is closed. A wire if is arranged in line with the body portion of the section B between the arms of the loop forming the catch H to brace said lVe claim:
The combination with the bag, of a sack fastener consisting of a sectional frame, each of the sections being substantially U-shaped and having the arms thereof hinged to the corresponding arms of the other section, the arms of .one section being arranged inside of the arms of the other section, and being of lesser length whereby to permit the body portions of the sections to pass each other when the bag is closed, the sections having the shorter arms being provided with an outwardly off-set portion, and the other section with an outwardly facing hook for engaging said outwardly off-set portion, whereby when pressure is applied to the inner surface of the bag to move the sections outwardly, the hook will be pressed firmly into engagement with the off-set portion.
