FINGER PIECE FOR THE SLIDERS OF SEPARABLE FASTENERS Filed April 18, 1936 INVENTOR DAV/J MAR/NJ/fl Patented June 13, 1939 OFFICE FINGER PIECE FOR THE SLIDERS OF SEPARABLE FASTENERS Davis Marinsky, Bronx, N. Y., assignor to Whitehall Patents Corporation, New York, N. Y., a corporation of New York Application April 18, 1936, Serial No. 75,084
2 Claims.
This invention relates to separable fasteners and particularly to the construction of sliders and finger, pieces of the sliders of fasteners of this kind; and the object of the invention is to provide a simple and economical method of forming finger pieces of the kind under consideration and to the construction of a slider to adapt the same for use in conjunction with the improved finger piece; a further object being to form the 0 finger piece of pull for sliders of the class described from die castings, thereby facilitating the production of the same in many styles or designs and of varying thicknesses throughout thelength 16 of the finger piece, and at the same time, elimiperienced'in stamped devices of this kind; a still further object being to provide a finger piece with a closed crosshead or pivot pin member constituting a unitary part of, the 'fingerpiece, and further, to the provision of a pin socket on a die cast slider for receiving the pivot pin of said finger piece; and with these and other objects in view, the invention consists in a slider and finger piece structure of the class described which is produced in accordance with the method hereinafter more fully described and claimed.
The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by'suitable reference characters in each of the views, and in which:
Fig. 1 is a plan view of a part of a separable fastener, showing one form of slider and finger piece made according to my invention.
Fig. 2 is a side view of a slider and the finger piece shown in Fig. l, with said parts detached.
Fig. 3 is a view similar to Fig. 2 showing the method of attaching or coupling the parts together. n
Fig. 4 is an enlarged detail view of a part of the construction shown in Fig. 3, illustrating the the method of closing and retaining the bearing of the slider in connection with which the finger piece is pivotally coupled.
Fig. 5 is a perspective view of a modified form of finger piece which I may employ; and,
Fig. 6 is a perspective view of another modified form of finger piece which I may employ.
- For the purpose of illustrating the type of device under consideration, I have indicated in Fig. 1 of the drawing, a part of a separable fastener. In said figure, 6 and I represent the tapes or stringers of the fastener, to one side edge of which are attached the coupling links or scoops 8 and nating all sharp corners or edges as commonly ex-- 9 respectively, which are adapted to be coupled and uncoupled by a slider 10 movable longitudinally of the stringers, and at II, I have indicated a finger piece or pull.
The slider ill, in the construction shown, is formed from a unitary body of die cast material and consists of upper and lower side plates I2 and I3 joined at one end by a transverse -V- shaped body It to form diverging channels l5 at the wide end portion of the slider, which channels converge at the other or narrow end of the slider. The side edges of the top and bottom walls l2 and I3 have inturned flanges l2a, But which serve to guide and retain the links or scoops 8 and 9 within the channels If).
Formed integrally with the top wall l2 of the slider is an upwardy extending bearing portion it which is normally formed substantially in the manner illustrated in Fig. 2 of the drawing to provide a semi-circular socket or recess I1 opening outwardly through one end of the member l6 and through opposite sides thereof. The top wall of the member l6 normally extends in the direction of the contracted end of the slider in the form of a projecting finger l8. At the base of said end of the member I6 is an upwardly extending portion i 9 having a semi-circular socket 20 in the upper surface thereof, into which the rounded end l8a of the finger I8 is adapted to seat when the finger I8 is moved into closed position to close the socket I! or to form thereof a circular passage for receiving the pin-like crosshead 2| at one end of the finger piece II to provide a pivotal mounting of the finger piece II in connection with the slider Ill.
The finger piece II is made from a body of die cast material, the outer or wide end portion 22 of which may be of any desired peripheral contour and characterized or ornamented on its upper and lower surfaces in any desired manner. This end portion is also preferably thicker than the end portion of the finger piece provided with the transverse pin 2|.
The pin 2! transverses a large opening 23 preferably inwardly of the free end of said finger piece to provide shoulder portions 24. The opening 23 serves to clear the member IS in the swinging movement of the fingerpiece uponv the slider- ),as well as to permit the insertion of a tool indicated in dot and dash lines at 25 in Fig. 3 of the drawing in the operation of bending or curling the projecting finger l8 around the pin 2| to form a complete circumferential bearing for the pin in the member l6 and also in the operation of moving the rounded end l8a of the finger l8 into the recess 20 to substantially key the finger l8 against accidental opening when subjected to stress or strain.
In this connection, it will be understood that the greatest strain upon the slider I is in the operation of closing the fastener, and in this operation, the finger piece H extends in the direction of the wide end of the slider and operates directly upon the portion |6a of the member l6 which is directly united with the top wall l2 of the slider; whereas, when the finger piece or pull II is operated, when in the position shown in Fig. 1 of the drawing, part of the stress or strain is taken up by the portion IQ of the member l6 which is also directly united with the top wall l2 of the slider. In the normal use of the device, there will be no danger of opening the pivot .bearing for the finger piece or pull.
In the construction shown in Figs. 1 to 3 inclusive, the top wall l2 of the slider is provided at one side thereof with an elongated aperture 26 which is in position to register with the spaces 3a or 9a between the links or scoops 3 and 9. The aperture 26 registers with the spaces 9a in the construction shown. At thecorresponding side of the finger piece or pull II is a downwardly extending pawl or finger 21 which is adapted to pass through the aperture 26 to engage one of the links 9 or to enter a space 9a between two links to retain the slider against accidental movement in the direction of opening or separating the stringers. The pawl 21 may be formed with a straight and curved side in the manner illustrated in Fig. 2 of the drawing, or this arrangement may be reversed. .In fact, the shape or form of the projection 21 may be made to suit various types of fasteners to control the movement of the slider on the stringers.
In Fig. 5 of the drawing, I have shown a detail view of a modified form of finger piece Ha, which has a transverse pivot or mounting pin Ma and an opening 23a substantially similar to the structure shown in Figs. 1 to 3 inclusive. At 21a, I have shown a projecting pawl or finger similar to 21, but in this modification, a supplemental projecting pawl or finger 21b is employed at the opposite side of the finger piece or pull and preferably arranged in staggered relation to the pawl or finger 21a so as to enter a recess 8a and to engage one of the links 8. The offset or staggered relationship of the fingers 21a and 28b compensate for the staggered arrangement of the recesses 8a and 9a.
With the construction shown in Fig. 5, the slider will have two apertures in the top wall thereof to receive the two projecting fingers 21a and 21b.
In Fig. 6 of the drawing, I have shown another form of finger piece having substantially parallel side Walls 28 and 29 which converge at the free end portion 30 of the finger piece, which end portion is provided with a large opening 3|. The other or pivoted end of the finger piece is provided with an opening 32 transversed by a pin member 33 which forms the pivot for said finger piece. In the construction shown, the
upper surface of the finger piece is recessed as the pin 33 and the side wall 23. The structure shown in Fig. 6 merely represents one of the many possibilities of design or ornamentation which may be carried out in manufacturing finger pieces from die cast material of any kind or class of material which is capable of being cast or molded.
The portions of the finger piece adjacent the opening 23 and connected by the member 2i may be referred to as parallel arms having upper and lower surfaces. These surfaces are bounded by the sides and ends of the arms; and said sides and ends may be termed the boundary edges of said surfaces. The projecting member 21 extends from one of said surfaces-and is completely surrounded by the surface; or in other words, the member 21 extends from a section of one of said arms and said section lies wholly within the boundary edges of one side surface of said arm.
By employing projections on the finger piece of the kind disclosed, the engagement of these projections with one of the links of the separable fastener when the finger'piece has dropped by gravity into a substantially closed position, will operate to draw the finger piece inwardly in the direction of the fastener, and prevent accidental release of the finger piece.
By constructing the finger piece or pull from a body of die cast material, a decided saving will be effected in the cost of producing as well as assembling the finger piece or pull with the slider, especially by employing a slider of the construction disclosed. In addition to this feature of economy, it is also possible to economically produce a wide range of styles or types of finger pieces or pulls with various markings or characteristics thereon which will better adapt the same to the many types of merchandise in connection with which articles of the kind under consideration are .employed. Furthermore, by casting a finger piece or pull, the same may be made of varying thicknesses throughout the length thereof to provide a more substantial and positively functioning pull, differing materially in this respect from the conventional sheet metal stampings heretofore employed as finger pieces and pulls for devices of the kind under consideration. By casting the finger piece or pull, the edges or corner portions thereof may be rounded to eliminate any objectionable sharp edges that might be injurious to the operator. As a whole, the entire device is enhanced in its appearance, and rendered more practical in use.
Another important feature of my invention re- 'sides in the fact that the projecting pawls or pull, as is necessary with the stamped type of device.
'I-Iaving fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
l. A finger piece for the slider of a separable fastener employing stringers with the slider movable longitudinally of the stringers for coupling and uncoupling the same, said finger piece comprising an elongated and relatively thin die cast body having at one-end spaced parallel arms integrally joined at the ends thereof by a transverse cylindrical pin forming a pivotal support therefor, each arm having upper and lower surfaces, a projecting member arranged longltudl-' nally and extending from onesurface of one of said arms, said member extending from the pin in the direction of the body portion of said finger piece and having adjacent the pin a perpendicular edge, the other edge of the member being curved, the elongated base of said member integrally joining the arm throughout the length of said base, and said base being substantially completely surrounded by said surface.
