SLIDER AND METHOD OF CONSTRUCTING THE SAME Filed July 30, 1943 l|illlllllllllllllllll WW loll/.5 0. woe/Al Patented Jan. 11, 1949 UNITED 'i STATES PATENT OFFICE Louis H. Morin, Bronx, N. Y., asslgnor of one-half toDavis Marinsky, Bronx, N. Y.
Application July 30, 1943, Serial No. 496,706
This invention relates to the sliders or separable fasteners employed to couple and uncouple the stringers by movement of the slider longitudinally of the stringers. More particularly, the invention relates to a die cast slider structure incorporating an insert, including the frog structure of the slider body, for producing greater strength in the resulting slider in accordance with the method more fully hereinafter described. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views; and in which:
Fig. 1 is a longitudinal sectional view through one form of slider, made according to my inventionfthe section being on the line I-I of Fig, 2, but omitting the die parts and cores shown in Fig. 2.
Fig. 2 is a diagrammatic sectional view through dies and cores employed for forming the structure of Fig. 1, the section being substantially n the line 2-4 of Fig. 1, but including the dies and cores around the slider structure.
Fig. 3 is a view similar to Fig. 1', showing another embodiment of the invention; and
Figs. 4, 5 and 6 are perspective views illustrating other types of insert frogs which can be employed.
In the construction of sliders of the kind under consideration, from die cast materials, and particularly when these sliders are fairly large and used upon separable fastener stringers employing relatively large links or scoops, the material employed in the conventional unitary castings, that is to say, sliders where the entire slider structure is formed from the cast material, is not always sufilciently strong to withstand the stresses ,or strains to which the slider may be subjected.
To overcome these objectionable features, insert frogs can be employed which will be composed of materials stronger than that employed in the cast slider to provide added strength and rigidity thereto. Further these inserts may be extended to include loops or other mounting members for attachment of the finger pieces or pulls commonly employed with sliders of the kind under consideration.
Where inserts are used in conjunction with metallic die cast sliders, the inserts will be composed of metals having greater strength than the material employed in the casting. In other in- ;;s tances, however, and where plastic castings are Y tionship to each other.
15 'Claims. (Cl. 24-40516) employed, the inserts themselves may be formed of die castings as well as of the other stronger metals or materials.
, In some instances, certain types'of the hard fibrous materials may also be employed as inserts in metallic aswell as plastic cast sliders.
In Fig. 1 of the drawing is illustrated one adaptation oi the invention in which the slider I0 is formed from spaced die cast members II and I2, which basically form the top and bottom plates or walls of the slider body, These walls include at the contracted endportion of the body the conventional inturned flanges I3. At It is shown an insert which unites the two bodies II and I2, and maintains the same in spaced rela- The insert comprises a frog portion I5, having recessed ends I6, I! keyed within the bodies I! and I2 respectively.
The insert I4 includes at the end I6 an outwardly and longitudinally extending rib llL-which reinforces the wall or body I I, and includes a portion I3 which is countersunk in the body I I. The other end ll of the insert includes an elongated loop 20, which forms the conventional mounting member for the finger piece or pull. The loop 20 includes a portion 2I imbedded in the body I2. The loop or member 23 also serves as a reinforcing member to reinforce the body or wall portion I2. It will be apparent that where reinportions 26 and 21 respectively of the slider body.
In this construction the pull or finger piece loop is formed by a member 23 cast integral with the wall 21.
To illustrate the method of forming die cast sliders with the inserts, I have diagrammatically shown in Fig. 2 of the drawing parts of two dies 23 and 30, and portions of two cores 3I and 32 for forming sliders of the type generally illustrated in Fig. 1 of the drawing. The core 3| has a forked end 33, producing an elongated channel 34 in which a pin or rod end 35 on the core 32 fits. This construction forms within the channel or recess 34 an opening 36 for the reception of the frog portion I5 of the insert I4. Whereas the ends 33 and 33 of the cores. 3| and 32 form the space or channels between the walls II and I2 of the resulting slider body, including the inturned flanges l3.
It will be understood that the adjacent surfaces of the dies 38 and 30 will be fashioned to receive the parts It and 20 of the insert, and otherwise fashioned to form the general contour of the slider. This includes the extended cast portion 31, which overlies a part of the member 30 where it joins the end ll of the insert. It will be apparent that with other types of inserts em- I ployed, the dies and core members will be correfined, said slider comprising a die cast body having spaced walls, an insert of denser, tougher material than said cast body, said insert comprising a frog portion centrally located with respect to the longitudinal axis of said walls with keying portions at each end thereof consisting of raised and depressed parts closely embraced by said cast body walls to form said slider.
2. A slider for fastener devices of the kind defined, said slider comprising a die cast body having spaced walls, an insert of denser, tougher material than said cast body, said insert comprising a frog portion centrally located with respect to the longitudinal axis of said walls with keying portions at each end thereof consisting of raised and depressed parts closely embraced are then closed, and the casting material is pressure injected through a suitablegate indicated In Fig. 5 of the drawing is shown a modified form of insert which is substantially similar to that shown in Fig. 3, with the exception that instead of having a rectangular cross sectional contour, the insert 39 is of more or less elliptical cross sectional form having a thick rounded end portion 40 and a thinner rounded end H which is directed inwardly or in the direction of the contracted end of the slider body when arranged therein. Both ends of the insert 39 are recessed, as seen at 42,'to provide the keying of the insert in the spaced walls of the slider body.
Fig.4 differs from the structure shown in Figs. 3 and 5, in using a round t cylindrical insert 43 with recessed ends 44. At this time, it might be well to point out that this type of slider construction lends itself to the formation of frogs of any desired shape and contour, and the inserts may be formed from sheet metal, forgings, or machined parts, and as indicated before, in
some instances may constitute individual diev will also be apparent from a consideration of Fig.1 that inserts of the general type and kind indicated'at 45 can be fabricated to include the pull supporting ring or loop similar to the loop member'zii.
In the use of inserts of the general type and kind illustrated in Figs. 1 and 6, I not only provide a stronger coupling between spaced walls of by said cast body walls to form said slider, one end of the insert including a part protruding beyond the slider wall, and forming a pull supporting member.
3. A slider for fastener devices of the kind defined, said slider comprising a die cast body having spaced walls, an insert of denser, tougher material than said cast body, said insert comprising a frog portion centrally located with respect to the longitudinal axis of said walls with keying portions at each end thereof consisting of raised and depressed parts closely embraced by said cast body walls to form said slider, one end of the insert including a part protruding beyond the slider wall, forming a pull supporting member, and part of the cast material of said wall extending onto the protruding portion of said member.
4. A slider for fastener devices of the kind defined, said slider comprising a die cast body having spaced walls, an insert of denser, tougher material than said cast body, said insert comprising a frog portion centrally located with respect to the longitudinal axis of said walls with keying portions at each end thereof consisting of raised and depressed parts closely embraced by said cast body walls to form said slider, one end of the insert including a part protruding beyond the slider wall, forming a pull supporting member, and the other end of the insert having a member extending longitudinally of the other wall of said slider body.
the slider body, but the extending arms of the insert also serve to' reinforce the wall structure of the slider body.
