Patent en Jan. 316', 192%.
Application filed. $eptember 3, 1919. Serial lilo. 821,384.
To all 107mm it may concern Be it known that "I, Anrnonr E. Wanner, a citizen of the United States, and resident of Edgewood, in the county of Providence and State of Rhode Island, have invented certain new and useful. Improvements in Joints for Pin Tongues, of which the following is a specification.
This invention relates to joints for pins, and has for its object to provide a joint member constructed with fulcrum fingers formed integral on the forward periphery of each ear, said fingers being bent toward each other to provide a forward fulcrum for the pin-stem.
A further object of the invention is to provide the bridge portion of the joint mem her that is very short in length relative to the diameter of the side ears, said bridge being provided with bendable legs for connecting it to a suitable base.
With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.
In the accompanying drawings:
Figure 1-- is an elevation of the joint member partly in section, the same being shown as connected to a base plate.
Figure 2-- is an enlarged view showing the shape of the joint member as blanked out of sheet stock and the relative shape and position of the fulcrum fingers.
Figure 3 is an enlarged front elevation of the joint member, showing the fulcrum fingers bent forward toward each other with their ends abutting.
Figure 4i is an enlarged sectional eleva tion of the joint member, showing the base in dotted lines, to which the joint member is designed to be attached. 7
Figure 5 is a top view of the base member.
Referring to the drawings, 10 designates a base member which is herein illustrated as made in an inverted bowl-shape and adapted to be connected to a celluloid bar 11 by being expanded in a recess 12 formed in the bar.
My improved joint member is preferably constructed from sheet metal stamped out into the form best illustrated in Figure 2 with ears 18--18. On the forward edge or periphery of each ear is formed a narrow finger portion 14:, the upper edge of each finger being substantially the same height from the bridge as through the center of the pivoting point in the ears.
The base portion 16 of each finger is comparatively narrow and forms but a very small portion of the circumference of the ear, that is the base of the finger does not .Xtend down to the bridge portion 17 of the joint member, thereby permitting this bridge portion to be made comparatively short in length, or of a length which is some what less than the diameter of the ears.
On the opposite ends of this bridge portion, I have formed bendable legs 15 which 7 0 of necessity must be comparatively close together so that they may pass through the openings 18 in the base member 10, which base member it is found in practice should be made small and inconspicuous as possible and it is therefore found to be necessary that the whole of each of these fingers should be supported on the periphery of the ear instead of extending down to said bridge portion as is the case with some other constructions.
After punching this blank from the sheet metal 3: bend the ears up from the common base or bridge portion 17 into the form illustratel in Figure 3, whereby the ears are parallel and spaced apart and between which the pin-tongue 19 is adapted to be pivotally mounted. The lingers ll1i are bent to ward each other from the opposite cars so that their ends abut at 20. In this position it will be seen that the pin stem 19 when mounted on the center pivot, or inwardly extending orotuberances, as the case may be, its lower edge, as shown in Figure 1, rests upon these fulcrum lingers and serves to provide the necessary spring or tension to hold the pointed end into engagement with the catch member 20.
By my improved construction of provid ing a fulcrum of fingers formed integral with the forward edge of the joint ears I am enabled to use the most inexpensive form of pin-stem which is that of bending one end of the round wire of the pin into an eye as illustrated in Figure 1.
The legs 1515 may be bent downward and passed through corresponding eyes in the base plate and then bent back with the ends abutting against each other as illustrated in Figure 1, thereby forming a very secure fastening to the base and that without the use of solder.
In practice the pin-stem and the joint connected to the base member 10, is sold as a complete finding to jewelers who do the mounting and finishing of the article ready for the trade.
I claim: 7
A pin-stern joint member formed of thin sheet stock folded to form a short bridge portion with two spaced apart upstanding side ears integral with the opposite edges of the bridge and adapted to mount a pin-stem in
