COMPLETE SPECIFICATION,
Improvements in or relating to the Construction of Metallic Bars
of that Class used for Supporting or Receiving the Glass for
Structural Purposes.
1, GEORGE MARTIN, of 61, Brook Street, Smethwick, in the County of
Stafford, Glazier, do hereby declare the nature of my said 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 comprised in the following Specification establishes my claim, and
relates to other improvements over a Patent granted to me and dated 5th May
1890, and No. 6904.
This my said invention relates to improvements in the construction or combi-
nation of parts forming metallic bars, of that character employed for supporting or
receiving the glass as used for structural purposes.
According to this my said invention in one part, my improved metallic bar
partakes of the form or character in cross section of the capital of letter (seraph T)
but in its application inverted; thus L this bar is produced by a process well
known and of a length and strength suitable to my requirement. The part of this
form known as the ridge taken vertically is provided with a series of oblong pierced,
apertures, the one end of which is increased in size by a step. A. double locking
stud of a required configuration is passed through the larger part and engaged
securely in the narrow part, this locking device is arranged in number, and distance
according to the length of bar and its application..
It will be perceived that the bar by means of the upturned edges forms two
ducts or troughs, one on each side of the ridge, and carry away any water, that by
accident may find its way therein. The sheets of glass are received and supported
by means of the upturned edges of the bar L upon which they find a bearing, and
according to their number and arrangement.
In some cases and by preference I should employ a metallic form partaking of
the capital letter S. the upper part of which would be engaged with the upturned
edge of the bar L. Such arrangement would be first made and the sheets of glass
finding their bearing upon the same, the object being to receive and convey the
moisture produced by condensation on the under or interior surface of the glass
into the lower part of the said form and carried away.
The remaining part of my improvements consists in the construction of a metallic
cap or cover for covering or secreting the internal arrangement of the component
parts of this bar, this cap or cover in cross section may be of any required shape
or configuration moulded so that its highest point will reach and bear upon the
apex, of the vertical ridge and its terminal edges reach down to and rest upon the
glass as above described. Both these metallic forms are drawn or rolled from
the sheet by tools specially constructed. The interior sides of this cap or cover
is provided with two metal "guide plates" in such a position that when the said
cap or cover is applied to the Ibar, and its terminal edges bear upon the glass it
can be slid along, and each guide plate engage with each stud and the double
locking arrangement is thus effected.
The upper edge of the ridge of bar L, is provided with a cross slot and the lower
part of said bar has two circular holes. A metallic stop plate in outline in
harmony with the cap or cover has a vertical slot, and two round pegs forming a
fork at its base, the two round pegs fit into the circular holes, when the vertical
slot in this stop plate is engaging with the ridge and finally the cross slot in same.
A most secure fastening is thus effected as all the parts are held in position.
The aim and object of my invention being simplicity in construction with economy
and durability

page_text: And in order that this my said invention may be more clearly understood I will
now proceed to describe the same reference being made to the sheet of drawings to
the various figures and letters marked thereon (that is to say).
Fig. 1. represents a side, view elevation of my improved metallic bar, and parts in
connection therewith as applicable to. its purpose.
Fig. 2. represents an end view elevation, cross section of same.
The same letters of reference upon each figure indicate the same parts.
a, is the metallic bar of the form of the seraph letter T, inverted thus L, b, is
the ridge, c. is the oblong aperture, d, being the larger part and e, the smaller,
f, is the double locking stud passed through d, and secured in e, g. g. are the
upturned edges forming the ducts or troughs h. hii, are the metallic forms
resembling, the letter S. the upper parts being engaged upon the upturned.
edges g., are the sheets of glass bearing upon i, i, but supported by g. g.
of a, the bar: k. k. are the lower parts or ducts for receiving the moisture from
condensation and removing same. In some cases I may dispense with i, i, then i, j,
would find its bearing and support upon g, g. 1, is the metallic cap or cover finding
its bearing upon b, at band its terminial edges l', ', upon the glass j. j; m, m, are
the guide plates connected to I, interiorally and engaged under the stud the
double locking being thus effected as illustrated by Fig. 2. and disengaged or
released as Fig. 1. is the cross slot in ridge b, o, o, the circular holes, p, is the
stop plate with vertical slot q. and round pegs 1, r. A., side view shews this stop
plate p, detached, and B, the said stop plate in application, and all parts securely
held in their respective positions.
'
The above being my said invention I wish to observe in conclusion that I do not
confine myself to the precise details or arrangement of parts as shewn on the
accompany sheet of drawings but that I hold myself at liberty to alter or modify
the same without departing essentially from my said invention. Neither do I
claim the construction of the several parts as hereinbefore specified taken separately
and apart from each other.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The construction of the metallic bar a, with ridge b, provided with
aperture c, for receiving double locking stud; also g. g, to form h, h, the ducts,
and to receive i; i,, when so 'required and glass j, j, also 7. the metallic cap or cover
provided with m, m, guide plates; also, in b, and o, o, for receiving the stop
plate p, for purposes substantially as herein-before set forth and described.
2nd. The general construction combination and arrangement of parts as herein
before described in the foregoing Specification and illustrated on the accompanying
sheet of drawings the whole forming "Improvements in or relating to the con-
struction of metallic bars of that class used for supporting or receiving the glass
for structural purposes."
