PIN FOR BROOCHES AND OTHER ARTICLES Application filed. Jui 1,

To all whom it may concern:

Be it known that I, FRED J. ENGEL, a citizen of the United States, and resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Pins for Brooches and Other Articles, of which the following is a specification.

One of the purposes of the present invention is to produce a bar pin or like fastening, for brooches and other articles in which a pivoted tongue is held in tensional engagement with its keeper, when in normal use, and prevented from rising more than is desirable when released.

Another object is to provide means combined with the tongue whereby it is given an effective resiliency when engaged with the keeper, and also an initial retarding effect tending to prevent the tongue from opening outward from the bar, even when freed from its keeper.

These objects are attained by the novel construction, combination and arrangement of parts hereinafter described and shown in the accompanying drawings, forming an essential part of this disclosure, and in which Figure l is a bottom plan view of a pin made in accordance with the invention.

Figure 2 is a side elevational view of the same.

Figure 3 is an enlarged fragmentary sectional view, the section being taken on the line 33 of Figure 4:.

Figure 4 is an enlarged transverse sectional view taken on line 4r-4 of Figure 3.

Figure 5 is a similar sectional view taken on the line 5-5 of Figure 3.

Briefly stated in general terms the invention comprises a bar or plate of any preferred contour, profile or shape, ornamented in any manner, as gem set or otherwise on its face, the back of its body being essentially flat and level.

Attached to the back near one edge is a hooked keeper and at a point, preferably removed so far as possible, a forked lug is secured in which is pivotally mounted a pin tongue having a conically tapering needlelike point adapted to engage the keeper in the usual manner.

In order to enter the pointed end of the pin tongue into the eye or bight of the hooked keeper, the end obviously must be 1921. Serial no. 481,775.

sprung outward and below the pointof the hook, and then inorder to prevent accidental displacement, the point must be strongly spring pressed against the bight of the keeper.

Referring now to the drawing, the numeral is used to designate the pin bar, here shown as a fiat elongated rectangular plate, having extending outwardly from its back, near one end, a rigid hook 11.

At the opposite end of the bar is a forked lug, its base 12 being secured by soldering, for which purpose an indentation 13 is formed centrally in the base, midway between the forks 1 A pin tongue head 15 is pivotally mounted between the forks on a pin 16 and extending from the head is the lever-like pin 17 terminating in a sharp point 18, adapted to enter the hook 11.

This can only be accomplished, as previously mentioned, by springing the pin laterally and at the same time towards the bar of the pin, in overcoming the inherent resilience of the pin material, it not being possible to rotate the pin tongue head upon its pivot suffioiently for this purpose due to the contact of a cam lug 19 upon the upper surface of the base 12.

As will be seen, the point of the cam strikes the base and acts as the fulcrum of a lever with respect to the pin tongue, before the head has turned sufficiently to bring the tongue parallel with the bar 10, so that the tongue may be slightly bowed when its point is engaged in the hook.

Due to the shape of the cam and its position, which is essentially at a right angle with the tongue, when the latter is forced to assume a plane substantially parallel to the bar, the cam acts to restrain the tongue from rising, even after it has been released from the hook, thus tending to prevent loss of the pin by inadvertent or accidental loosening of the point.

However, a slight pull exerted on either the bar or tongue suffices to cause them to separate at the hook end and the tongue may be turned freely outward to such an angle as to permit it to be readily freed from the material with which it may be used, this angle being limited by contact of a stop 20, formed in the head 15, and a detent 21 raised from the base 12 opposite the indentation 133.

be made in its construction, without the exercise of invention or conflicting with the scope of the claims hereto appended.

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

1. A bar pin or the like comprising a rigid bar element, a keeper and forked lug secured to said bar at a distance apart, a spring tongue having a head pivoted between the forks of said lug, a sharp pointed cam on said head co-operative with said lug for stressing said tongue when engaged in said keeper, the point of said cam being in advance of the axis of the tongue pivot and at substantially a right angle to said bar, a detent on said lug between the forks thereof,

and a stop on said head engageable with said detent when the tongue is raised respective to said bar.

2. A bar pin or the like comprising a rigid bar element, a keeper and a forked lug secured to said bar, a tongue having a solid flat head pivoted in said lug, said head presenting'a curved profile at the rear, a sharp pointed cam in advance of the pivot point, said cam including an angle of approximately sixty-five degrees, its rear edge being closely tangent to the pivot to a point radial therewith and thence radially outward to the curved portion joining the same at an acute angle, the point of said cam impinging on the lug between the forks thereof when said tongue is engaged by said keeper, and a projection on said lug en aged by the rear angular element of the tongue shank.

This specification signed and witnessed this 21st day of June, 1921.
