I Specification of Letters Patent.
Patented Jan. 1, 1907.
Application filed October 12,1906. Serial rt. 338,576. I v
To (tZZ whom it may concern: Be it known that I, NEIL McINNEs, a citizen of the United States of America, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Pressed- Steel Connecting-Bars, of which the followmg 1s a specification, reference being had therein to the accompanying drawings.
This invention relates to pressed-steel connecting-bars adapted for use as car-truck levers, connections for the, sivitch points of railway-switches, and for other purposes.
The primary objectof the invention is to provide a pressed-steel connection of light but strong and durable construction capable of being manufactured at small expense of labor and material.
The construction of the improvement will be fully described hereinafter in connection with the accompanying drawings, which form a part of this specification, and its novel features will be defined in the appended claims.
In thedrawings, Figure l is a top planview ofa blank from which the improved connec- ,tion'is made. Fig. 2 is a side elevation of a connection constructed in accordance with the same. Fig.
the invention. Fig. 3 is a top plan view of 4 is an end view thereof. Big. 5 is a transverse section 011 the line :20 :1: of Fig. 2, and Fi 6 is a similar section illustrating a mod'ifie construction.
The reference-numeral 1 designates a blank comprising a flat steel plate, longitudinally slotted and perforated at its ends to to shown in Figs. 2
provide parallel arms 2, rounded at their outer extremities 3. The blanlr as thus formed is then pressed at one operation to the form to 5, inclusive. The body form in cross-section and is deflected upward portion 4 of the blank is bent to invertedU at the points 5, and the arms 2 are brought into'vertical parallel relation with ings 6 of each pair of arms registering, as
7 shown. This prrssingof the blank provides a body portion of great strength and'rigidity and projects the ends and perforated arms upward to facilitate their attachment to the elementsto which they are to be secured. v
the open- The construction of the complete device requires .only' two opcrations-viz., the stamping out of the blankand'tlie pressing of thesamc to completed form.
In Fig. 6 I have shown a transverse tion of a slightly-modified construction, in which the side walls latter being pressed into the parallel relation shown in Fig. 5 are pressed inward toward each other, which form maybe preferred for certain purposes.
This modification will involve an additional step or operation in the process of manufacture; but such further operation will add to 'thecompactness and finished appearance of the connection.
What I'claimpand desire tosecure by Letters Patent, is-
I 1'. A pressed-steel connection comprisin a blank formed at its ends with longitudinal slots and having its body portion pressed to inverted-U shape in cross-sectionv 2. A ressed-steel connection comprising a fiat bl ank longitudinally slotted and perforated at its ends, and pressed to provide a body portion of inverted-U shape in crosssection, and parallel upwardly-directd arms.
3. A pressed-steel connection comprising a body portionof inverted-U shape in crosssection having its ends upwardly inclined, and provided with parallel perforated arms.
4. A pressed-steel connection comprising a blank longitudinally slotted at its ends and rounded and perforated, and having the body portion pressed into inverted-U shape. in cross-section, and provided with verticallyf disposed perforated arms.
5'. A -pressed-steel connection comprising a blankslotted and perforated at its ends and pressed to provide a body portion the side walls of which are deflected toward each other, and to bring the perforated ends into vertical parallel relation.
In testimony whereof I affix my signature in the presence of two Witnesses.
