SAFETY PIN.

Application filed August 30, 1922.

To all whom it may concern:

Be itknown that we, AARON J. SMITH and Fos'rnn T. FREDERICK, citizens of the States, residing, respectively,

5 the county of Cook and State at Chicago, in the county of of Illinois, have jointly invented certain new and useful Improvements in Safety Pins, of which the following is a specifica- 0 tion. i v

Our invention relates to an improvement in safety pins, and has for its-primary objectthe provisionnof a safety pin whichis locked when in closed position against opening and which cannot readilyflbe opened when in closed position without .a combinat1on of movements designed to disengage the.

pin from the head and to free end of the open it.

Another and further object of our" invention is the provision of a safety pin which is primarily adapted for laund T work and'at the same time is equally adaptable ,for any purpose where safety pins may be employed,

use in fastening childrens clothes, in that it is securely looked against opening by the child, or accidental. 7 opening either by becoming bent. due to the strain-imposed upon the or other material through which the pin passes, or by the frictional the clothing uponthe head of the pin.

Another and further object of .our' invena larger capacity than isusual for'the same length pin in that it can be inserted through more clothing or other articles adapted-to be fastened by the pin than is common with member instead of at the bottom of thepin as is common with pins-of this class, s'o'that the, body of the pin can readilybe passed throughthe material to a farther extent than is common with'the usual form of: safety pin, the." spring coil also serving to hold the material in place, preventing wear and tear of the material through which the pin passes." 7

'Another and further object of our inven tionis the provision of a safetypin which I can be manufactured cheaply, which i's'efficient and simple in operation and which is effectually looked against"opening even though the pin may be bent, resulting in the United 7 t at Chicago, in

of Illinois,'and Cook and State Pin by the, clothingtion is the provision of a safety pin having :pins of this characterfin that weprovide a spring coil in the rear portion of the body- Serial No. 585,138.

unfastening or loosening of the free end of the pm as s common in pins of this characer. c Y These and further objects of our invention will be more fully-and better understood drawlngs andinwhich- Figure 1 is aside elevational view of our improved safety pin showing the pin in closed position;

igur'e 2 is-.an elevatio'nal ViGW partially in section showing the pin in closed posii- Figure 3 is a detailed'vertical sectional view on lines 3-3 of- Figurel,

F igure is a detailed side elevat-ional view of the pin head shown in Figure 3.

' 12 are provided, the front portion 12 being theffree portion of: the pin, having the usual bend I2 at the bottom thereof, with a coil 13 formed approximately midway interme-' diate the ends of the rear portion 11 so that an added amount of elasticity is provided in the rear portion 11' of'the pin. The upper part 14 of thejrear portion. 11 is curved until it forms approximately a half circle, terminating at 15 adjacent the free end 16 of the front portion 12 of the :pin. On the curved portionlt is mounted a head 16, the said head-being composed'of'a thin strip of metal bent so as to provide a flat side wall portion 17 with a similar'opposite fiat sidewall portion l8with curved marginal edges, the rear side of which engage the upper end of-the portion 11, and :the front side formsa pocket for the reception of the free end 16 of the portion 12, 'A rivet which "extends through the walls17-and18 ofthe head 1 6on the inside ofthe curved portion letyservingto'hold the head '16 in position upon the eurved portion 14'of the pin and in limited "slidingengagement therewith, so that the head portion 16 can be moved slightly upon'the" curyed-fportion 14,0f the in; the limit of. outward' movement being by reference to the accompanying sheet-of or stud "19 is provided,

"teg ral with the wall 17 or determined by the engagement of thestud 19 with the curved p0rtion'14,;as shown in Figure 2. Depending from the side wall l'iof the head 16is a spring portion insecured thereto, as may befound desirable, the spring 20 ex tending upward and diagonally across the inner space of the head 16 from the lower portion of the wall 17 to the wall 18, where a portion 2110f the spring 20 is bent outwardly and passes through an opening 22 in the wall 17 and has a head 23 formed thereon outside of the wall 17, the spring 20 movement of the hands, namely, i-ng out'of the spring with theportion 14: by lifting the head forming the locking means for holding the head 16 in its lowermost position upon the body ofthe safety pin by engagement of the portion 21 of the'spring 20 with the in side of the curved portion 14 of the pin. Depending from the wall 18 is a lip 2% formed the head portion 16 and which.

integral with serves as a locking member for the free point 16 of the 1pin when the head is in its lowermost or 100 ed position. At the lower portion ofthe wall l 8 is an arcuate shaped recess 25 adapted, when the head of the pin is in its extended position',to allow the free end 16 ofthe pin to be disengaged from the pocket in the head 16 and pass outward therefrom into open position shown in Figure 2.

The coil 13 on theyrear portion of the pin allows the pin to be inserted the full distance through articles or material which is hold together by the -pin, such as 'laundry bags or the like, all ofthe'way up to the coil 13,

instead of being limited by a coil usually placed at the point "121 on the pin, and providing an additional amount of elasticity inthe body'of the pin so that when the free end 16% is disengaged the pin automatically opens.

In operation the device is exceedingly simple but effective and requires a combined .the pull- 20 from engagement inany suitable n'ianner'so that the portion 2 of the "spring is out of engagement with the portion 14 of the body, andthis allows the head 16 to slide outward until the pin 19 is in engagement Wlth the portion '14: of the body of the pin, whereupon, the safety pin then inserted isunfastened in the usual manner of saftey pins by pressing-the free point 16 inwardly until it can be pushed sidewise through the arcuaterecess 25 in the side walls 17' and 18.

When itis desired to close the pin after being-inserted through the material, the p re- \VQISG operation take's'place. The free end r 1 ofxthe pin is pushed inwardly until it is op- 'posi te 'theareuate shaped recess 25 and is against the inner side of the wall '18 between the walls 17 and 18, whereupon the point "is released and it passes out p wardlyinto the pocket in'the head'16 in the position shown inFigure 2; The head 16 is thereupon pushed downward until the horizontal portion 21 ot the sprlng is below the curved portion 14, whereupon the spring snaps into place underneath the curved portion of thehe-ad, thus holding the head socurely inposition until the spring is released. As the head 16 is pushed downward the lug 24 is positioned behind the free end or point 16 of the pin as shown in Figure 1, thus ell-actually locking the point 16 of the pin against opening; g

In addition to the engagement of the locking lugf2 l, the upper edge of the arcuate shaped recess 25 is a sufficient distance below and the proportion of parts and the substi-' tution of equivalents as circumstances may suggest or render expedient without departing from the spirit orscope of our invention.
