JOHN S. BOYD, OF BALTIMORE, MARYLAND.

BUCKLE.

SPECIFICATION forming part of Letters Patent No. 364,210, dated June 7, 1887.

Application filed April 11, 1887.

To all whom it may concern.-

Be it known that I, JOHN S. BOYD, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Buckles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in buckles to be used for various purposes, and espeeiall y to be usedin connection with my improved bag and inspection flap, application for which is made of even date herewith.

As ordinarily constructed, buckles have been made so that the natural tendency of the tongue is to close, or, having been closed, to It is found in practice, however, that there often arises a necessity for a buckle which will normally tend to fly open, and which is only kept from so doing by the pressure of the fabric with which the prong engages, and it is to meet this demand that I have invented the device hereinafter specified and claimed.

In the accompanying drawings, forming a part of this specification, and on which similar letters of reference indicate the same or corresponding features, Figure 1 represents a plan view of my improvement, showing the same as it appears when not in use; and Fig. 2 isa eross-seetional view taken on the line a: 90 of Fig. 1.

The letter A designates a frame of the usual or any approved construction, the same being preferably made of sheet metal, so that it can be readily and easily stamped out, though it may be cast. The frame in this instance is of rectangular form, though not necessarily so, and the inner edge, B, of the forward bar, 0, is depressed, so that when the buckle is in use and the teeth or prong is engaged the said prong will impinge against the depressed edge B, and the points of the teeth, being in a plane below that occupied by the surface of the frame, will not hurt or scratch any one who may be engaged in handling goods provided with my'improved buckle.

The side bars, D, at a point somewhat forward of the rear bar, E, are provided with inwardly-proj ecting supporting arms or lugs F, which terminate in pivotal points. These Serial No. 234,878. (No model.)

arms may be cast separately and then soldered or otherwise secured to the side bars, or they may be made integrally therewith, as in the present instance.

The letter G refers to the tongue, the same being, preferably, also made of sheet metal and having one or more teeth or prongs, H, there being three shown. The rear edge, or that edge opposite the prongs, is bent over upon itself in such a manner-as to form hollow spindles I, into which the arms F project, and thus support the tongue.

The spring J, in the present instance a spiral spring, has the end K bent toward the rear of the frame and under the tongue. The spring on the other side is similarly constructed, so that the normal tendency of the springs is to force the tongue, not against the edge B, but away from it, so that it is only the hold of the fabric upon the teeth that keeps the tongue held against the edge B.

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

1. In a buckle, the combination, with the frame thereof, provided with bearings, of a tongue having arms mounted upon the bearings and a spring mounted in proximity thereto in such manner as to normally keep the tongue away from its seat.

2. In a buckle, the combination, with the frame thereoflhaving its forward bar depressed and the side bars provided with supportingarms, of a tonguev having teeth and mounted upon said arms, and a spring arranged in such relation to the tongue and arms as to normally keep the tongue away from its seat.

3. As an improved article of manufacture, the herein-described buckle, the same consisting of a frame having the inner edge of its forward bar depressed and its side bars provided with supporting-arms, a tongue whose spindles are mounted on the said arms, and a spiral spring arranged with relation to the tongue and arms in such manner that the tongue will normally fly away from its seat- In testimony whereof I affix my signature in presence of two witnesses.

JOHN S. BOYD.
