ANTON DVORAK, OF SHADYSIDE, OHIO.
SAFETY rm.
Application filed December 15, 1926. Serial No. 154,982.
This invention relates to and has for one of its objects to provide a safety pin with novel, simple and inexpensive means for locking the free or pointed end of its penetrating bar in the guard therefor.
With the foregoing and other objects in View, the nature of which will become apparent as the description proceeds, the invention consists of the construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawing,
wherein:
Figure 1 is a view partly in elevation and partly in section of a safety pin embodying the invention,
Figure 2 is a top plan view of the safety P Figure 3 is a sectional view taken on the plane indicated by the line 33 of Figure 1, and
Figure a is a similar view taken on the plane indicated by the line l4 of Figure 2.
Referring in detail to the drawing, in the several views of which like reference characters denote like parts, 1 designates the back bar, 2 the penetrating bar, 3 the spring loop and 4; the guard of a safety pin.
In accordance with my invention, the safety pin is provided with a locking memher 5 which is adapted to hold thefree or pointed end of the penetrating bar 2 against casual withdrawal from the guard 4c. The locking member 5 comprises a shank 5 loop 5 and thumb piece 5. To adapt it for the application thereto of the locking member 5, the guard 4 is provided in its front side with a longitudinally extending slot 6 having a laterally enlarged inner end 6 The shank 5 passes through the slot 6, and the loop 5* is located within and the thumb piece 5 without the guard 4. The loop 5 contacts with the inner face and the thumb piece 5 with the outer face of the front side of the guard i to secure the locking member 5 against endwise movement with respect to the guard. The locking member 5 is free for adjustment longitudinally with respect to the guard 4 in order to permit it to be moved inwardly into active and outwardly into inactive position. When the locking member 5 is in active position, the
loop 5 engages the free Or pointed endof the penetrating bar 2, and due thereto holds said end against casual withdrawal'from the guard 4. Then the locking member 5 is in this position, the shank 5 is in the laterally enlarged end 6 of the slot 6, and due thereto the locking member is held against casual movement into inactive position. When it is desired to move it into inactive position so as to release the penetrating bar 2, and thus permit of the withdrawal of the penetrating bar from the guard 4:, the lockfing member 5 is first moved laterally to position the shank 5 in alinement with the slot 6, and thereafter moved outwardly as far as the slot will permit.
From the foregoing description, taken in connection with the accompanylng drawing,
it will be apparent that the locking means is of such construction as to-require comparatively little alteration in safety pins to adapt the latter for the application of the former, that the locking means will not materially increase the cost of the safety pins, and that the locking means may be readily adjusted to secure the penetrating bar of the safety pin in its guard and readily adjusted to release the penetrating bar for withdrawal from the guard.
What is claimed is In combination, a safety pin having the front side of its guard provided with a longitudinally extending opening having its in ner end laterally enlarged, a shank passing through the slot and adjustable longitudinally of the guard, a loop secured to the inner end of the shank and adapted to receive the free end of the penetrating bar of the safety pin, and a thumb piece secured to the outer end of the shank, said loop and thumb piece contacting with opposite faces of the front side of the guard, and said shank being adapted to occupy a position in the enlarged end of the slot to hold it against casual movement with respect to the guard.
In testimony whereof I affix my signature.
ANTON DVORAK.
