PIN FASTENER. APPLICATION FILED 012L301 i920.
Patented'Apr. 19; 1921.
1 v I LH INVENTOR.
STAT ANDREW w. KosKr AND HOMAS CASEY, on rrrcnizcne, MASSACHUSETTS.
'rIN-FAsTEivER.
T 0 all whom" c'tmay concern:
Be it known that we, ANDREW W. KosKI and THOMAS CASEY, citizens of the United States, residing at Fitchburg, in the county of Worcester and State of .Massachusetts,
have invented-certain new and useful Improvements in Pin-Fasteners, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to improvements in pin fasteners. 7
An important object of the invention is to provide means for fastening the piercing ends of .brooch bar pins or the like which is free from the use of springs in its construction, thereby providing a device which is comparatively long lived. I
A further object of the invention is to provide-a device of this character having as few working parts as possible and having its Working parts of such formation that they may be readily formed by die-stamping the same from sheets of metal, thereby materially reducing the cost of construction.
A still further object of the invention is to provide a device of this character in which the locking of the pin is accomplished by the closingof the pin and is positive in its nature. r
Other objects and advantages of the invention will become apparent throughout the course of the following description.
In the accompanying drawings, wherein for the purpose of illustration is showna preferred embodiment of our invention, and wherein like reference characters designate like parts throughout:
Figure 1 is a side elevation partly in section of a pin fastener'constructed 1n accordance with our invention;
I Fig. 2 shows the fastener engaged by the by the fastener, and I Fig. 4t is a section on the lined- 4 of- Fig. 3 shows the pin completely locked Specification of LettersPatent. 1 Patgntgd Apr, 19, 1921, Application filed October so, 1920. Serial No. 420,756;
adjacent the ears 11 being provided with divergent guiding portions 15 for directing the point of the pin between the ears. v
Mounted in the ears 14 is a pivot pin 16 upon which is mounted for oscillation a plate 17. This plate has formed therein a slot 18 which'forms in the plate an overhanging Er s.
It will be seen that if means is provided ond plate 22 embodying spaced arms 23- and 24, hereinafter to be referred to as the dog and operating arm, respectively. This plate is likewise provided with a thumbpiece '25 which normally extends downwardly and engages against the end of the bar. While the plate is in the position illustrated in Fig. 1 ifthe pin is moved downwardly the point thereon engaging against the striking piece 20 will causethe plate '17 to rotate, During this rotation, after the overhanging portion 19is so positioned that it overlies the end of the pin, the under surface of the striking piece 20, as indicated at 26, engages against the extremity of the operating arm 24 causing the plate 22 to shift about its pivot. At this time the notch 21 is alined with the dog 23 so that the dog 23 may enter the same and further downward movement of the pin causes the dog to seat firmly in the closed position. The plates 17' and 22 will, of course, have a certain degree of frictional engagement with the adjacent facesof the ears -14 inorder to prevent accidental displacement thereof. When the plate 17 is in the locking position and the plate 22 shifted so that the dogthereof en-I gages in the notch 21, the thumb piece 25 is shifted away from the end of the bar 10. When it is desired to release the pin from its locking engagement this may be readily accomplished by moving the thumb piece 25 inwardly to engage the end of the bar, in which position the plate 17 may be rotated to release the pin. In addition to the binding engagement of the plates 17 and 22 with the surface of the ear 14:, it is found desirable that the dog 23 during its movement'both into and out of the notch 21 should have a slight binding engagement with the outer surface of the plate in order that the movement of the plate 17 both into and out of the locking positions may be accomplished with a slight snap. For this reason the dog 23 is provided upon its inner surface with a small lug, as at 27.,
It will be obvious that the construction hereinbefore set forth, by reason of its simplicity, durability and the ease with which it may well adapted for the purpose for which it is intended; and it will likewise be obvious that the construction hereinbefore set forth may be somewhat altered without in any manner departing from the spirit or use of our invention. We, accordingly, do not limit ourselves to the specific structure here-1 inbefore set forth, except as so limited by the subjoined claims.
What we claim is:
1. In a pin fastener, the combination with a pin pivoted to swing in a given direction a pivot plate mounted in the path of the free end of the pin and pivoted to swing in the same plane therewith, saidplate being provided with an overhanging portion, said pin upon its engagement with said plate, rotating the same and causing said overhanging portion to overlie the free end of the pin, a second plate provided with a dog, a dogreceiving notch formed in the first named plate, means actuated by the rotation of the.
first named plate for rotating the second named plate to bring the dog thereof into engagement with said notch, the engagement of the dog within said notch preventing the rotation of the first named plate in a direction opposite to the direction of rotation imparted thereto by said pin.
2. In a pin fastener, the combination with a body portion having a pin pivotally connected therewith to swing in a given plane,
of a pair of spaced ears approximately parallel to and arranged upon opposite sides of the plane of swing of said pin, a plate pivotally connected intermediate said ears and provided with a slot forming in said plate an overhanging portion and a striking piece causing rotation of said plate be manufactured, is particularly and causing said overhanging portion to overlig the free end of the pin and means actuated by the rotation of said plate for positively locking the plate against rotation.
3. In a pin fastener, the combination with a body portion having a pin pivotally confree end of the pin'and means actuated by the rotation of said plate for positively looking the plate against rotation,'comprising a second plate pivotally mounted intermediate and embodying a dog and an operating arm, said first named plate having a notch formed therein and opposed to said slot, a portion of said first named plate engaging said operating arm and causing rotation of, sald second named plate to bring the dog thereof into engagement with said notch.
4. In a pinfastener, the combination with i a body portion having a pin pivotally connected therewith to swing in a given plane,"
of a pair of spaced ears approximately parallel to and arranged upon opposite sides of the plane of swing of said pin, a-plate pivotally 'mounted intermediate said ears and provided with a slot formingin said' 2 plate an overhanging portion and a strikingpiece causing rotation of said plate and causing said overhanging portion to overlie the free end of the pin and means actuated by the rotation of said plate for positively locking the plate against rotation comprising a second plate pivotally mounted intermediate and embodying a dog and an operating arm,
said first named plate having a notch formed therein and opposed to said slot, a portion of said first named plate engaging said oper:
ating arm and causing rotation of said second named plate to bring the dog thereof into engagement with said notch, said dog having a binding engagement with the edges of the first named plate during its movement into and out of engagement with said notch. j
In testimony whereof" we hereunto affix our signatures.
ANDREW w. KosKi THOMAS CASEY.
