FRANCIS ROBERT SILK 26 Brighton Road Balsall Heath Birmingham Commercial
Traveller do hereby declare the nature of this invention to be as follows:-
I take 2 pieces of metal, formed in a die or with tools to the required shape of the
Eye to fit the Stair Rod, which may be of any pattern or shape, and fasten the 2 pieces.
together with Eyelets Rivets or Screws, preferably Eyelets the Eyelets fastening the
pieces together and will form the Screw Holes or other holes necessary for fixing
the Eyes.
The Stair Eye may be formed in 2 pieces secured together by the Screws Nails or
pins necessary for fixing to the Stairs.
The Stair Eye may be made from one piece of metal shaped to the pattern required
and fastened with Eyelets Screws or Rivets.
The Stair Eye may be braized or Soldered together.
Instead of using loose eyelets, I stamp the metal in the shape of an eyelet and
unite them together with a punch.

Improvement in the Manufacture of Stair Rod Eyes.
I, FRANCIS ROBERT SILK of 26 Brighton Road, Balsall Heath, Birmingham in the
County of Warwick, Commercial Traveller, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention has for its object principally, to simplify the construction and
manufacture of stair rod eyes.
This invention consists in forming stair rod eyes, from two blanks, cut from sheet
metal, and subsequently fashioned, by shaping tools and pressure; and thus forming
a back and a front part, which are united, or fixedly secured together, by eyelets,
whose holes form passages through which attachment screws or pins pass. Or the
connection may be made by rivets; or the turning over of the extreme ends of the
one, over the extreme ends of the other. Or the one may be connected to the other,
by bulging inwards the metal of the one, so as to form eyelets or necks, over which,
holes in the other part, pass; and on the boundary edges of the bulged connections
being turned over, the two parts are fixedly secured together.
Having described the nature of my invention, I will now proceed to describe with
reference to the accompanying drawing, the manner in which the same is to be
performed.
Figure 1 represents in front elevation a stair rod eye, constructed and made accord-
ing to my invention. Figure 2 represents an end view of the said stair rod eye,
which is made from two cut out blanks of sheet metal, subsequently shaped or
fashioned, and united together by eyelets, which form the sinkings or countersunk
holes, through which the attachment screws pass, in securing the eye to the tread of
a stairs. Figure 3 represents a longitudinal vertical section, (upon an enlarged scale)
on the dotted A B figure 1, the said stair rod eye. This view exemplifies how the front
and back parts are united together. Figure 4 represents in end elevation, the two
shaped or fashioned blanks separately, while figure 5 represents in front elevation
and section, an eyelet, by which means, the said parts as aforesaid, are fixedly con-
nected together. Figure 6 represents the blank of the front part, and figure 7 the
blank of the back part. Figure 8 represents the front or the shaped blank of the
front part, while figure 9 represents a front elevation of the shaped back part.

page_text: Figure 10 represents a inodification in which the back part is fixedly secured to the
front part, by bulging inwards a portion of the metal of the said front part, so as to
form necks or eyelets, which on the inside boundary edges being turned over the
metal of the boundary edges of holes in the back part, the two become fixedly
secured together.
The same letters of reference indicate corresponding parts in figures 1 to 9 of the
drawing.
a is the front part, and is the back part; the front part is bowed or swelled out-
wardly about its middle, and is marked a², and with its terminal ends or flaps a³,
directed in planes, at right angles to each other; and near the ends a³ of the said
front part, are holes or piercings a'.
This front part a is cut out from sheet metal, which is subsequently shaped into
the desired form as represented in front elevation figure 8.
The back part b consists of a similarly shaped blank as the front part, but with the
middle part thereof, bent inwardly; so that on the front and back parts being
brought together, and with the inner part of the one, in juxta position to the outer
part of the other, they enclose a space about their middles, which is of the desired
section of a stair rod with which the eye is to be used. Thus 62 is the inwardly
bulged middle part, 63 the flanged ends, following the contour of the front ends,
and are holes or piercings, which are coincident with the piercings at of the other
part; and which said parts a and b, are fixedly secured together by an eyelet c
passed through the said piercings a, 64, and then clenched by means commonly
known.
By thus securing together the backs and the fronts of stair rod eyes by means as
described, the axial hole of the eyelet thus employed, forms the passage through which
scrows pass in attaching the said articles to a stairs.
In figure 10, a is the front part, and bis the back part as before; a² the front bulged
part, and the inwardly bulged back part. a³ is the front flange, and 63 the back
Hange the former has an inward bulging c, and with the extreme edges c² turned
or flattened over the edges of holes or piercings made in the said back, coincident
with the bulged piercings in the front, and by which means, the two parts are
connected together, without employing separate and independent eyeletings.
By constructing and manufacturing eyelets as described, the said articles are
greatly simplified in their means of production.
The shape of the middle parts is dependent upon the cross section of the stair rods
with which the said eyes are to be used; as for instance, when the rod is cylindrical or
circular, then the enclosing space of the eye is circular accordingly so that the
exact shape of the said eye, is made to suit the exact cross section of a rod.
Instead of employing eyelets, the fronts, and the backs, may be united together, by
rivets, or by turning the ends or flaps a³, of the front part a, over the extreme flanged
ends of the back part b, and then clenching the turned over metal, which fixedly
secures the two parts a and b together.
Instead of the bulged eyelet being made from the front part, it may be made from
the back part, and the parts secured together as previously described.
The swelled back and front parts may if necessary be made of very thin metal, and
made wave-like, so that the same shall yield and grip a rod; thus proventing dis-
placement and chattering, which commonly occurs when metallic rods and eyes are
placed loosely, metal to metal, on vibration or jarr occuring.
Having now particularly described and ascertained the nature of my said invention;
and in what manner the same is to be performed, I declare that what claim is.
First. Making stair rod eyes from two cut out and shaped blanks of sheet metal ;
and constituting a front and back which are connected together, near or at their
ends, by eyelets, rivetings, or by the extreme ends of the one, being turned over the
extreme ends of the other, substantially as described and illustrated.
Secondly. Connecting together the front part, and the back part, of stair rod eyes

page_text: of the kind herein-described, by eyelets, or eyeletings, which pass through coincident
holes in the respective front and back parts, substantially as described and set forth.
Thirdly Connecting together the front and back parts of stair rod eyes of the
kind as herein described, by bulging from the metal of one of the said parts, solid
eyelets or necks, which pass through corresponding and coincident holes in the other
part and on the boundary edges of the said solid eyelet or neck, being turned over
and upon the metal surrounding the holes of the other, the two parts constituting the
eyelet, are fixedly secured together, as described and set forth in figure 10.
