Specification of Letters l aten t. Patented 19, 1918.

Application filed October 23, 1914. Serial No. 868,26

To all whom it may concern:

Be it known that I, ORLANDO C. Fnrznn, a citizen of the United States, residing at Sterling, in the county of \Vayne and State of Ohio, have invented certain new and useful Improvements in Safety-Pins, of which the following is a specification.

his invention relates to pins and more particularly to that class of pins known as safety pins wherein a cap or the like is provided over the pointed end of the pin to prevent injury to persons using the same.

The object of my invention is to provide a pin of the above class which is simple in construction, strong, durable and cheap to manufacture.

Another object of my invention is to provide a pin in which the point thereof is absolutely rendered safe when the same is once fastened in place.

With the above and other objects in view my invention resides preferably in the construction, combination and arrangement of parts as set forth in the following specificaion and illustrated in the accompanying drawings, in which:-

Figure l is a view showing my improved pin in place, and serving as a retaining means for a watch to prevent the same from dropping from the pocket;

Fig. 2 is a side elevation of myiniproved pin showing the same with the protecting cap in position; and

Fig. 3 is a similar tecting cap removed distended.

Similar reference characters indicate similar parts throughout the various views of the drawings.

Referring more particularly to the drawings in which the preferred embodiment of my invention is illustrated, I provide a pin having a semi-spherical head 1, said head 1 having extending therefrom a pin shank 2, the base of said pin shank 2 being secured in a socket as at 3 within the head 1. As noted in Fig. 2 the shank 2 of the pin does not extend exactly at right angles to the fiat face 4 of the semi-spherical head 1 but is slightly inclined or distorted from the vertical for a purpose which will hereinafter become apparent. The head 1 is provided with a lug 5, to which is secured a resilient element comprising a coil spring 6, the opposite end of the coil spring 6 being secured on 2 lug.- 7 carried by the cylindrical cap 8.

view showing the proand the spring element The said cap 8 is provided with a longitudinally disposed recess 9 which is adapted to receive the pointed end 10 of the pin shank A soft and yielding material 11 is provided in the inner end of the recess 9 against which the pointed end 10 of .the pin is adaptedto impinge, of the point owing to contact with the metal of the cap. The pin as shown in F ig. 2 is in closed or protected position and is illustrated with the cap removed in Fig. 3. The object of the shank 2 inclined relative to the head 1 is to facilitate the engagement of the cap 8 over the pin point 10. It will be noted that the resilient element 6 and the shank 2 of the pin 'ex' tend in substantially parallel relation so that it is only necessary to draw the cap 8 and the head. 1 away from one another inorder to disengage the said cap 8 from the pointed end of the pin. ,1 r

It will be noted that by having the head 1 semi-spherical and provided with the consequentially formed fiat face 4, the pin and the lug may be extended therefrom. The

lug is carried adjacent the opposite sideof the head from which the pin pin fitting within the socket as hereinbefore specified. It will be noted by referring to Figs. 1 and 2, when the pin is in use the spring is of such length as to beentirely closed, thus forming an even grip by which the structure may be handled, without danger of the operator injuring or pinching his hands. It will also be noted that as the spring is connected to the lugs 5 and 7 of the head 1 and cap 8, the cylindrical reduced construction of the cap will cause the cap to be positioned in such a manner as to cause the pin to be brought across the central plane of the head 1 in an off-center manner, thus causing a binding action upon the end of the pin for holding the ment with the head 1 and also preventing the accidental removal of the cylindrical cap. It will also be noted that the surface of the spring is in direct alinement with the recess and for this reason the operator may place the spring in engagement with the point of a pi'n,.or having the point bearing thereagainst and upon releasing the spring gradually, the tension thereof will move the pin along the springand then guide the same into the recess in the cap, thus eliminating unnecessary trouble in positioning the cap over the point of the pin;

2 extends, this so as to prevent mutilation being slightly p111 111 engage One application of my invention is illustrated in Fig. 1 wherein a watch pocket or the like 12 is illustrated, my improved safety pin being disposed in substantially parallel relation with the upper marginal edge of the pocket and secured to the body of the coat or the like 13. A. watch l l is illustrated as disposed in the pocket 12 in dotted lines having a chain 15 secured thereto. The chain'lo being disposed between the coil spring 6 and the shank 2 of the pin whereby to secure the watch within the pocket'and prevent the same from dropping therefrom, when the pocket is inverted. This is but one illustration of the various uses to which my improved pin may be put and I do not desire to be limited to the same.

One great advantage ofmyinvention over the usual type of safety pins is that the same is capable of longer life, as the safety pin, as usually constructed, places-the spring or resilient portion in the shank 2 of the said pin, and it is a well known fact that such g ins soon loose their resiliency owing'to the spring becoming devitalized. It will be seen in my improved construction that I have provided a pin which overcomes the above objections and provides a number of desirable features which are not found in the ordinary type of safety pins. There are not as many parts involved in my invention as in the usual safety pin and therefore this will tend toward a cheapness of manufacture.

From the above description taken in connection with the accompanying drawings it is thought that a clear and comprehensive understanding of my invention may be had by those skilled in the art and While I have shown and described my invention as pos sessing a peculiar form and construction it is desired that it be understood that I may make such changes in the details thereof that do not depart from the spirit and scope of the invention as claimed.

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

In a safety pin of the class described, the combination of a semi-spherical head having a flat inner face, a lug projecting from said face adjacent the periphery of said head, said head also having a pocket formed therein adjacent the opposite side thereof with respect to the side adjacent which the lug is formed, a tapering pin carried by said pocket and extending therefrom, a spring carried by said lug, a cylindrical cap having a lug extending therefrom adjacent its periphery, said last mentioned lug being secured to said spring, thus connecting said spring to said head and cap, said cap having a longitudinally disposed recess formed therein, the surface of said spring being in alinement with said recess, thus constituting a guide for assisting in directing the point of the pin into said recess, said pin extending across the central longitudinal axis of said body to constitute an off-center bearing of the cap upon the pin, thus preventing the accidental displacement of the point of the pin, and said spring being of such length as to be entirely closed when holding said cap upon said pin, thus preventing injury to the operators fingers in gripping the spring, when the pin is in use, owing to the even outer surface of the spring.

In testimony whereof I aifix my signature in presence of two witnesses.
