SAFETY-CATCH FOR PINS, BRoooHEs, AND THE LIKE,

Specification of Letters Patent.

Patented Aug. 12, 1919.

Application filed November 10, 1915. Serial No. 60,631.

which the following is a specification.

This invention relates to that class of safety catches in which a catch is pivoted at the base of the hooked keeper with one arm' lying inside the keeper adapted to close the same and the other arm projecting at the closed side of the keeper, a spring normally holding said catch in closed position.

The objects of the invention are to provide a spring which engages the arm inside the keeper to close the same; to employ a substantially V-shaped catch; to secure compactness and a neat and inconspicuous appearance; to locate the spring as well as one arm of the catch inside the keeper; to secure. simplicity of construction and operation, and to obtain other advantages and results as'maybe brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate the same parts throughout the several views,

Figure l is an underneath or back view of a pin or brooch to which my safety catch has been applied;

Fig. 2 is an edge view of the same at right angles to the pin shaft;

Fig. 3 is an edge view transverse to the pin shaft locking at the open side of the keeper and fromthe side thereof toward which the shaft opens;

. Figs. 4 and 5 are, sections on the line AA Fig. 1 showing the safety catchin closed and opened position respectively;

Fig. 6 is a perspective View of the keeper partly in section, and

Fig. 7 is a perspective view of the keeper before its feet are turned into parallel planes.

"In the specific embodiment-of the inven tion shown in said drawings, .1 indicates a body portion of a pin, brooch or similar article of any kind having a pin shaft 2 pivotally connected at one end to the body portion as at 3 and adapted at its pointed end to engage beneath a keeper 4:. My improved safety catch is applied to this keeper 4 for the purpose-of retaining the pin shaft against inadvertent escape as will beunderstood.

The keeper 4 is apertured near its base or attachment to the body portion 1, in a plane transverse to that in which the pin shaft 2 swings, and in this aperture is pivoted a somewhat V-shaped catch 5' with its arms extending upward and projecting one at the open side of the keeper and the other at the closed side, as clearly shown-in the draw ings. 'When the catch is rocked on itspivot to cause the arm 6. to lie against the back or closed side of the keeper, the other arm 7 extends to or toward the extremity of the' hook portion of'the keeper so asto close the opening of the keeper against escape ofthe pin shaft, as shown in F igsq3 and 4. On the other hand when the arm 6 is swung away from the back orclosed side of the keeper as shown in Fig. 5 the other arm 7.

swings inwardly beneath the hooked portion r of the keeper past the pin shaft 2 so that said pin shaft may be freely released from the keeper. l L1 The particular purpose of my inventionis to provide spring means directly engaging the arm 7 to hold the catch 5 normally in closed position as shown in Figs. 3 andi' l,

and to thisend 1 stamp out of the keeper itself a spring 8, leaving the same integrally attached at the point of the hook portion of the keeper but free from the keeper at its opposite end and for its entire length. Preferably this spring Sis stamped out as clearly shown in Figs. 6 and 7, and comprises a median strip of the keeper as shown in Fig. 7. Stamping it out thus provides the aperture in the keeper above referred to to receivethe V-shaped catch, and afterward the. feet .9, 9 ofthe keeper, which is of a-single thickness of sheet metal are twisted a quarter turn as shown in the drawings. .The end of the spring 8 is then cut ofl' sufficiently to allow it to lie between the arms of the V-shaped catch, as shown and said spring is given a set or normal position which durable and effective. Furthermore, the spring 8 does not project so as to cause any obstruction, nor is it conspicuous in any way so as to detract from appearances. In fact the said spring occupies space which would otherwise be used for nothing, and is hardly noticeable. At the same time it effectively holds the catch always in closed position unless it is positively opened by the user. Instead of the spring being integral with the keeper, it of course could be mounted thereon in any suitable manner to accomplish the results set forth herein.

Obviously, many modifications and changes may be made in manufacturing my improved safety catch without departing from the spirit and scope of the invention, and I do not wish to be understood as restricting myself except as required by the following claims when construed in the light of the'prior art.

Having thus described the invention, what I claim is:

1. In a device of the character described, the combination with a hooked keeper, of a pivoted catch having an arm lying inside said keeper and adapted to close .the same and another arm projecting at the closed side of the keeper, and a spring engaging the said arm inside the keeper to normally hold it in closed position.

2. In a device of the character described, the combination with a hooked keeper, of a pivoted catch having an arm lying inside said keeper and adapted to close the same and another arm projecting at the closed side of the keeper, and a spring between said arms of the catch engaging the said arm inside the keeper to normally hold it in closed position.

3. In a device of the character described, the combination with a hooked keeper, of a pivoted catch having an arm lying inside said keeper and adapted to close the same and another arm projecting at the closed side of the keeper, and a spring projecting from the hooked portion of the keeper into engagement with the said arm inside the keeper to normally hold it in closed position.

4. In a device of the character described, the combination with a hooked keeper, of a substantially Vshaped catch pivoted at the base of the keeper with one arm lying inside said keeper and adapted to close the same and another arm projecting at the closed side of the keeper, and a spring engaging the said arm inside the keeper to normally hold it in closed position.

5. In a device of the character described, the combination with a hooked keeper, of a substantially V-shaped catch pivoted at the base of the keeper with one arm lying inside said keeper and adapted to close the same and another arm projecting at the closed side of the keeper, and a spring between said arms of the catch engaging the said arm inside the keeper to normally hold it in closed position.

6. In a device of the character described, the combination with a hooked keeper, of a substantially V-shaped catch pivoted at the base of the keeper with one arm lying inside said keeper and adapted to close the same and another arm projecting at the closed side of the keeper, and a spring projecting from the hooked portion of the keeper into engagement with the said arm inside the keeper tonormally hold it in closed position.

7. In a device of the character described, the combination with a hooked keeper, of a pivoted catch having an arm inside the keeper adapted to close the same, and a spring projecting from the hooked portion of the keeper into engagement with said arm to normally hold it in closed position.

8. In a device of the character described, the combination of a hooked keeper having a leaf spring stamped longitudinally out of its hook portion with its free end away from the free end of the hook, and a catch pivoted to said keeper and normally held in closed position by said spring.

9. In a device of the character described, the combination of a hooked keeper having a spring stamped out of the longitudinal middle portion of its hook part with its free end away from the hook and its other end near the point of the hook, and a catch pivoted in the aperture formed by stamping out said spring and normally held in closed position by said spring.

10. In a device of the character described,

'the combination of a keeper having a spring stamped out of the longitudinal middle portion of its hook part with its free end away from the hook and forming a slot opening through the opposite end of the keeper, and a V-shaped catch pivoted in said slot and normally held in closed position by said spring.

11. In a device of the character described, the combination of a hooked keeper formed out of sheet metal and having a spring stamped out of the longitudinal middle portion of its hook part with its free end away from the hook and forming a slot opening through the opposite end of the keeper, the portions of the keeper on opposite sides of the open end of said slot being twisted sub stantially a quarter turn to form parallel feet, and a catch pivoted in said slot and spring.
