SAFE TY-PIN.

Specification of Letters Patent.

Patented Aug. 18, 1908.

Application filed May 1.0, 1907. Serial No. 373,010.

To all whom it 'may concern:

Be it known that I, LAWRENCE W. KING, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Safety-Pins, of which the following is a specification.

This invention relates to safety pins and my object is to produce an article lof this character which can be easily manipulated, will perform its function efiiciently and reliably and is of simple strong, durable and cheap construction.

To this end the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which,

Figure 1, is an enlarged perspective view of an article embodying my invention. Fig. 2, is a central longitudinal section of the same. Fig. 3, is a front view of the same. Fig. 4, is a pers ective view of the front end of the base p ate. Fig. 5, is a plan view of the front end of the spring. Fig. 6, is a side view of a modified construction of the pin. Fig. 7, is a view of the opposite side with the guard moved to permit the pin point to be disposed between it andthe base or withdrawn from between the saine. Fig. 8, is a horizontal section taken on the dotted line VIII of Fig. 6. Fig. 9 is an edge view and Fig. 10 a fragmentary face view of a modified form of safety pin.

Referring to the drawings in detail where similar reference characters indicate corres onding parts, 1 indicates an elongated base p ate provided at its rear end with a hinge oop 2. Near its front end are incisions 3 in its opposite edges the portions forward of the incisions being provided in Figs. 1 to 4 inclusive with a set of incisions 4, the incised forward portions being bent to provide upwardly projecting walls 5, the said forward portions being also bent upwardly to provide corresponding walls in the modified construction, though in the latter said portions are not incised. The forward portions of said walls at the base of said incisions in Figs. 1 to 4inclusive are bent to provide the outwardly .projecting fianges 6, and the base plate between said incised walls is provided with a comparatively large opening 7.

S indicates a substantially inverted-U- shaped shield'or guard which fits over the forward portion of the base and externally embraces snugly walls 5, the depending portions or arms of the shield or guard, of Figs. 1 to 4 inclusive, being provided with longitudinal slots 9 both terminating at their front ends, by preference, in downwardly extending portionslO. In the modified form only Olne side wall is provided with a longitudinal s ot 9. slots 9 are engaged with a sliding relation by the outwardly projecting flanges 6.

Riveted as at 11 or otherwise and superposed with respect to the base plate is a spring 12, which spring fits between the side walls of the base and is equipped with outwardly projecting portions 13 engaging the slots 9 or their portions 10 forward of fianges 6, said spring tending to press downwardly so as to secure the shield or guard in its normal position by causing portions 13 to engage slot portions 10 below the plane of the body portions of the slots, as shown clearly in Fig. 1.

The pin proper, numbered 14, preferably consists of a pair of substantially parallel tines 15 sharpened at their front ends and united at their rear ends by a depending U- shaped portion 16 pivotally connected or hinged to the hinge loop 2, said pin proper being of such length as to be covered by the shield or guard 8 when in its normal or protecting position. In the modified construction one ofthe walls 5 is provided in its upper edge near its front end with a notch 17 and the opposite wall near its rear end is provided with a longitudinal slot 18, adaptedto regisy ter ywith the slot 9 of the shield or guard when the latter occu ies its operative position.

In the mod' ed construction, the spring, fitting between walls 5, is preferably constructed of spring wire bent to substantially U-form with a loop or arch at the junction of one of the arms with the bridge portion, the said arm being numbered 19, the arch or loop 20, the bridge portion 21 and thev other arm 22. Said spring is arranged parallel with the base plate with its arm 19 extending through walls 5 forward of notch 17 with the rear portion of the loop extending inwardly through said notch, and the free end of arm 22 projecting outward through slot 18, preferably In the preferred construction the f5 about midway the length of the latter, the

of Fig. 7 is rovided near its frontend and in its lower e ge with a notch 23, which registers, when the shield or guard occupies its normal position, with the notch 17, the provision of the slot of said shield or guard forward of said notch forming a lug 24 rounded at its rear and lower corner so as to be capable of pivotal operation in the arch or looped portion of the spring, said lug and the opposite wall of the shield or guard being pivoted on the arm 19 of the spring as shown clearly. The slotted wall of the shield or guard of the modified construction is provided with an opening'25, to form a mouth for the slot, the

front wall of said mouth being beveled as at 26 so that when the shield or guard is moved pivotally from the position shown in dotted to the position shown in full lines Fig. 6, the said beveled wall 26 will engagev the spring arm 22, and force the same rearward until it enters slot 9 when it will spring forward in said slot and thus lock the shield or guard against reverse or opening movement until' the operator by the pressure of his thumb finger on the projecting end of the spring arm 22 shall force the latter rearwardly into the vertical plane of the opening ory mouth 25 and hold it in such position until with his nger or otherwise he swings said shield or guard upward. It will be noticed that the notch 23 straddles the rear portion of the arch or loop 20 when the shield or guard is closed as shown in Fig. 8. The pin proper in its operative position has its front end-or ends asy it preferably comprises a pair of tines-superposed with respect to the spring as in the preferred construction and under the shield or guard when the latter occupies its operative or locked position, the arrangement being such in both instances, that the pin proper is reliably held and its point protected when the shield or guard occupies its normal position.

To operate the shield or guard of the preferred construction so as to free the pin proper, the operator places the index finger upon the shield or guard and the thumb against the base plate over opening 7 and applies a squeezing pressure so that his thumb will pressthe spring toward the top of the shield or guard until the projections 13 of the spring are in line with the body portion of slots 9` As this is accomplished hev moves his thumb and linger in opposite directions in parallel planes and thereby impar-ts relative opposite. longitudinal movements to the base plate and the shield or guard, such movement being limited by the contact of flanges 6 with the rear ends of slots 9. These movements withdraw the shield or guard from over the points of the pin so as to permit the latter to be swu away from the base plate and forced through the object or objects to be pinned. After the pin has been swung back to its original position opposite movements from those de`- scribed are imparted to the base plate and guard to cause the latter to recover the points of the pin, the portions 13 of the spring snappin down into the depending portions of the wal s 9 to resecure said parts in their normal or originalpositions. j

To manipulate the structure shown in Fig. 6, the operator presses forward with his thumb nail on the projecting end of spring arm 22 until thelatter is op osite the mouth 25 of slot 9. He then wit his finger and while holding the spring with his thumb, raises the shield or guard. The pin proper f ismanipulated as before and after its return to position the shield is restored to its original position as hereinbefore explained.

In the construction disclosed by Figs. 9 and 1'0 the base plate 1 extends forward bel yond the shield or guard and is provided g5 with a roll 27, at each side. The hook pin is produced by bending a piece of spring wire to form the connecting portion 28, the parallel arms 29 which extend through said rolls and the hooks 30, the rolls and the arms 29 stiffening and strengthening the base plate. By connecting the hooks 30 by the cross piece 28 no soldering or riveting is necessary to secure the hook pin in position. A safety pin of this character can be pinned to one edge of a garment in the usual manner and the hook pinv be employed to secure the other edge o n the garment. It is of course unnecessary to describe other connections in which the combined safety and hook pin of Figs. 9 and 10 may be employed.

From the above descri tion it will be apparent that I have pro uced a safety pin possessing the features of advantage enumerated as desirable and I wish it to be understood that I do not desire to be restricted to the exact details of construction shown and described except as limited by the scope of the appended claims, as obvious modiiications will suggest themselves to one skilled inv 11o the art.

Havingthus described the invention what I claim as new and desire to secure by Letters Patent, is zy 1. A safety in,lcomprising abase late or 1'15 member rovided with upturned wa s at its fronten a substantially inverted-U-shaped rshield or guard member slidingly enga ing said walls, a pin attached to the base p ate and having its point between the latter and 4120 the shield orguard, and a spring fitting between the base plate and the shield or guard and engaginfT one of said members to revent accidental s iding movement where y the point of the pin would be exposed.
