JOINT FOR PINSTEMS Filed Dec. 4, 1929 IN VEN TOR.
ATTORNEYS.
Patented July 22., 1930 warren STATES PATENT OFFICE ANTHONY E. WALLER, OF PROVIDENCE BHODE ISLAND- JOINT FOR PIN STEMS Application filed December 4, 1929. Serial No. 411,491.
This invention relates to an improved construction of joint for pin stems; and has for its object to provide a joint member of this character which is constructed with one or more outwardly-extending fingers formed on the forward edge of one or both of the ears,
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. 7 In the accompanying drawings:
F ig. l is an elevation of the joint member partly in section showing the base or bridge portion of the joint as soldered to the base plate.
Fig. 2 is a view of the joint member in extended position. I
Fig. 3 shows the joint in end elevation with both its side ears and fulcrum fingers folded into working position.
Fig. l is the same as Fig. 3 showing the pinstein in section as mounted upon the joint ears and bearing on the fulcrum fingers.
Fig. 5 is a top view of the joint member with the pinstem removed, showing the ful It is found in the practical construction and operation of oint members for pinstems, particularly those of the smaller sizes, of advan tage to form the fulcrum arms integral with the pivot ears and arrange them to extend the fulcrum point for the pinstem as far away from the pivoting point as possible without causing the joint member to look too large and clumsy, which extended position of the fulcrum gives a better support to the pinstem and increasesthe effectiveness of its-spring or resiliency to better retain its pointed end -1I1 1ts catch member; and the following is. a
detailed description of, the present. embodiment of my invention and showing one arrangement of fulcrum fingers by whlch these advantageous results may be accomplished.
\Vith reference to the drawings, 10' designates my improved catch member which is provided with a short bridge portion 11 which has side ears 12 formed integral therewith and folded to extend upwardlyfrom opposite edges thereof.
This bridge member serves as a suitable base or support to be soldered in position on the base plate 13 of the pin. a The joint ears l2 be pierced or they may have inwardlyextending pivot projections 14 which cooperate to provide between them a suitable pivot which extend from. opposite sides into the C elry; and particularly in joint members of these small sizes, it is found of advantage to form the fulcrum of a pair of fingers 19, each of which is formed integral with the forward edge of its pivotear, and that it is of advantage to position this fulcrum point 20 as.- far from the pivot point as possible, I have f-ormedthese fingers of a length considerably greater than one-half the distance between the ears whenfolded into working position and I have curved these extending fingers" so that they may abut each other and provide a fulcrum a substantial distance outwardly or forwardly from the forward edges. of the pivot ears;
Inpracticethe outer'end's: of these fingers-. may-or maynot abut. Asfillustrated in Fig.
6, this pinstern is under its; greatest strain while its. pointed end i-s-ibein'g passed aro nd itsfpoint 17 of. the catch. 18', at which time this pinstein is swungloff to oneis ide and at a considerable distance from its normal working axis thereby carrying its fulcrum point to one side of the center of the bearing portion of these fingers.
By my improved construction, I am enabled to provide a pinstem joint which is very neat in appearance and which by the arrangement of its fulcrum arms provides a fulcrum point for the pinstem a substantial distance forwardly from the pivoting center of the pinstem thus providing the maximum support for the pinstem to assist the resiliency of the pin to prevent inadvertent disengagement from itscatch member in which the pointed end of the pinstem is housed.
I do not wish to limit myself to the use of a pair of arms, one on. each ear, as in some instances a single arm, may be employed as a fulcrum for the pinstem.
The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechani cal changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
I claim:
1. A pinstem joint of sheet stock shaped and folded to form a short bridge and attaching base portion and having two spaced upstanding side ears integral therewith between which ears a pinstem may be pivotally mounted, and a fulcrum finger extending outwardly from the forward edge of one of said side ears and inclined inwardly toward a center line between said ears to provide a fulcrum for the pinstem which is located a substantial distance beyond the forward edge of said ears.
2. A. pinstem joint of sheet stock shaped and folded to form a short bridge and attaching base portion and having two spaced upstanding side ears integral therewith between which cars a pinstem may be pivotally mounted, and a pair of fingers formed on the forward edge of said ears to extend outwardly therefrom and inclined toward each other, said fingers providing a fulcrum for the pinstem located a substantial distance beyond the forward edge of said side ears.
3. A pinstem oint of sheet stock. shaped and folded to form a short bridge and at taching base portion and having two spaced upstanding side ears integral therewith between which ears a pinstem maybe pivotally mounted, and a pair of fingers formed on the forward edge of said ears to extend outward ly therefrom and inclined toward each other, the combined length of said fingers being greater than the working distance between said ears, said fingers providing a fulcrum for the pinstem located a substantial distance beyond the forward edge of said side ears.
In testimony whereof I afix my signature.
ANTHONY E. WALLEB.
