METHOD OF MAKING STEEL TABLE-SLIDES.
Original applications filed November 23, 1906, Serial No. 344,676, and November 28, 1906, Serial No. 345,433.
' Divided and this application filed. January 20, 1908.
To all whom it may concern:
Be it known that I, ()RRIN G. FnANKs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a Method of Making Steel Table-Slides, of which the following is a specification.
This invention is an improvement in extension-table slides, and relates more especially to the method oi? making such slides from sheet-metal, being a division of my prior applications for patents filed November 28d, 1906, SerialNo. 344,676, and November 28th 1906, Serial No. 345,433.
The present invention contemplates the formation of the several parts or sections of the slide from strip of metal which is bent along both its longitudinal edges to provide companion rail members or ways, whereby the center section of the slide is produced by simply cutting the metal strip so formed into the required length, and the side sections or parts of the slide produced by first cutting the strip transversely to give the length. of said section and. then dividing such length longitudinally, each side section thus produced having a rail-member and an attaching flange, the rail-member being adapted to slidably engage a companion rail-member on the aforesaid center section.
In the accompanying drawings illustrating my improved method of forming steel slides for extension-tables: Figure 1 is a plan view of a metal strip embodying my invention. Fig. 2 is a transverse sectional View through the same. Figs. 3 and 4 are views of the side sections of the slide formed from such strip. Fig. 5 is a plan view illustrating a slight modification in the shape of the rail-members or Ways at the edges of the strip. Fig. 6 is a transverse sectional view through the strip illustrated in Fig. 5. Figs. 7 and 8 are views of the side sections of the slide produced from the strip illustrated in Figs. 5 and 6.
In carrying out my invention a metal strip or steel plate of suitable length is first bent along its opposite longitudinal edges to provide companion rail-members or ways which are of such relative shape as to be adapted for slidable engagement one with the other, whereby the several parts or sections of an extension-table slide may be produced by Specification of Letters Patent.
Patented July 6, 1909.
Serial No. 411,805.
simply cutting up the metal strip into suitable lengths.
In Figs. 1 to 4 oi' the drawings I have shown the rail-111embers of the strip shaped to form companion loops adapted to mesh one within the other for interlocking slidable engagement, while in Figs. 5 to 8 I have shown another form in which the rail-members at the opposite edges of the strip are similarly constructed and are adapted for in terlocking slidable engagement.
Referring now to Figs. 1 to 4, the metal strip therein shown and from which the several parts or sections of a slide are produced, is bent or shaped to form a straight body portion 10, at one longitudinal edge of which is formed a looped portion or Ushaped railmember 11, the said loop being turned outward and at the upper end of its free member provided with an inwardlypr jecting retaining flange 12, the upper surface of which latter is disposed on a plane with the under surface of the body portion 10 of the strip. [it the other edge of the strip is a rail-member 13 in the form of a loop which is turned inward, and the upper edge of the free member of said loop terminates a distance below the underside of the body of the strip approximating the thickness of the flange 12 of the other rail-member. This rail-member or loop 13 is smaller than the rail-member or loop 11 so as to nest within the same, and when said loops are slidv longitudinally one within. the other the retaining-flange 12 of the loop 11 will overlie the free member of the loop 13 and lock the loops or rail-members in slidable engagement with each other. By forming the opposite rail-members oi the strip so that they are adapted to engage one with the other, when the strip is cut transversely into two lengths and one of said lengths divided longitudinally, on the line c-a Fig. 2, the undivided length or part will constitute the center section of the slide (in dieated by Fig. 2) while the other parts will constitute the two side sections of the slide (indicated in Figs. 3 and 4), each comprising an attaching flange and a rail-member, the latter being adapted to slidably engage the companion rail-member oi the center section.
In Figs. 5 to 8 I have shown a different form of rail-member, but as will be observed said members are so formed that one may have an interlocking slidable engagement with the other, so that the several parts of the slide may be produced by cutting up such strip in the same manner as described with reference to the strip shown in Fig. 1. In this modification the rail-members at the opposite edges of the strip are alike, and therefore a description of the rail-member at one edge of the strip will refer also to the other, lixe numerals of reference being employed. In this form oi the invention 1 designates the body or intermediate portion of the strip which is bent at its longitudinal edges to provide a vertical portion 15, an inwardly-projeeting shoulder 16, and a loop portion 17 turned outward, the free member of said loop terminating a short distance above the shoulder. Nhen this strip is divided to form the several parts of the slide those parts or sections shown in Figs. 7 and 8, comprising the side pieces or sections of the slide, are turned or reversed so that the looped rail members thereof may slidably engage with the correspending looped rail-members of the center section, as indicated in dotted lines in Fig. 6;
and it will. be noted that when thus connected the shoulder of one rail-member will overlie the loop portion of the other rail-member, thereby forming the interlocking engagement mentioned.
Though I have shown in each instance the conventional three-part slide it will be obvious that a slide having a greater number of parts or sections may be produced by simply adding one or more center sections. It is also obvious that the shape of the rail meinbers may be modified or changed without sacrificing any of the advantages of my invention By this particular method of making sheet metal or steel extension-table slides it is only necessary to operate upon a single strip or plate of metal to form the several parts 01' the slide, and therefore the strip may be passed through suitable rolls to form the rail-memhers at its opposite longitudinal edges.
Having described my invention, what I claim as new and desire to secure by Letters Patent is:
The method of making extension table slides which consists in providing a metal plate or strip, bending said metal plate or strip at its o'iposite longitudinal edges to form rail-menibers or ways, the rail-member or way at one edge being adapted for interlocking slidable engagement with the railmember or way at the other edge, cutting said plate or strip transversely, and then dividing one of the parts longitudinally.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
