"IMPROVEMENTS IN FASTENINGS FOR JOINING MILL BANDING, AND FOR OTHER
LIKE PURPOSES."
My Invention consists of the improvements herein-after described in fastenings
for joining mill banding, and for other like purposes, by which improvements the
fastening is made very light, strong, and effective, and may be readily applied and
removed. Further, the fastening is flat, and when in use is practically flush with
the surface of the band to which it is applied.
In constructing a band fastening according to my Invention I take two pieces of
sheet brass or other strong sheet metal of a length about double their width. Near
one end of the piece of sheet metal I make two oblong slots or holes in the same
line, and the other end of the piece of metal I form into two prongs, the said prongs
being of a length somewhat greater than the thickness of the two ends of the
band to be joined. The two pieces of sheet metal are fashioned in a similar way,
and the prongs on one end of each piece are of a size and shape proper to enter the
slots or holes near the end of the other piece. The prongs are bent into a planc at
right angles to the other part of the piece of sheet metal.
In using the fastening two pairs of holes are made in the overlapping ends of the
band at the requisite distance apart for the prongs of the two parts of the fastening
to pass through. One part of the fastening is placed under the ends of the band,
and the other part is placed over the said ends of the band. The prongs of the two
parts are inserted in the two pairs of holes described, and the two parts of the
fastening are pressed together. As the two parts approach each other the prongs
which have been passed through the boles described in the ends of the band pass
through the oblong slots in the said parts of the fastening, the prongs of the under
part passing through the slots in the upper part, and the prongs of the upper part
passing through the slots in the lower part.

page_text: The two parts of the fastening when pushed home lie flush or nearly so on
the upper and under sides respectively of the band. By now clenching or bending
down upon the band the protruding ends of the prongs on the upper and under
sides of the band the two parts become firmly locked together, and the ends of
the band are securely joined together.
When the band is of great width two or more of the fastenings may be employed
side by side so as to extend the connection of the ends of the band through their
whole width.
Although I have only described my Invention in its application to the joining of
mill bands yet my Invention may be applied to the joining of other bands and to
other like purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Samuel Andrews in the Great Seal Patent Office on the 3rd February
1877.

"IMPROVEMENTS IN FASTENINGS FOR JOINING MILL BANDING, AND FOR OTHER
LIKE PURPOSES."
My Invention consists of the improvements herein-after described in fastenings
for joining mill banding, and for other like purposes, by which improvements the
fastening is made very light, strong, and effective, and may be readily applied and
removed. Further, the fastening is flat, and when in use is practically flush with
the surface of the band to which it is applied.
In constructing a band fastening according to my Invention I take two pieces of
sheet brass or other strong sheet metal, which I generally prefer to be of a length
about double their width. Near one end of the piece of sheet metal I make two or
more oblong slots or holes in the same line, and the other end of the piece of metal
I form into two or more prongs, the said prongs being of a length somewhat greater
than the thickness of the two ends of the band to be joined. The two pieces of
sheet metal are fashioned in a similar way, and the prongs on one end of each piece
are each of a size and shape proper to enter the slots or holes near the end of the
other piece. The prongs are bent into a plane at right angles to the other part of
the piece of sheet metal.
In using the fastenings when two prongs are used two pairs of holes are made in
the overlapping ends of the band at the requisite distance apart for the prongs of
the two parts of the fastening to pass through. One part of the fastening is placed
under the ends of the band, and the other part is placed over the said ends of the
band. The prongs of the two parts are inserted in the two pairs of holes described,
and the two parts of the fastening are pressed together. As the two parts approach
each other the prongs which have been passed through the holes described in the
ends of the band pass through the oblong slots in the said parts of the fastening,
the prongs of the under part passing through the slots in the upper part, and the
prongs of the upper part passing through the slots in the lower part.
The two parts of the fastening when pushed home lie flush or nearly so on the
upper and under sides respectively of the band. By now clenching or bending
down upon the band the protruding ends of the prongs on the upper and under
sides of the band the two parts become jointly locked together, and the ends of the
band are securely joined together.
•
When the band is of great width two or more of the fastenings may be employed
side by side, so as to extend the connection of the ends of the band through their
whole width.
Although I have only referred to my Invention in regard to its application to the
joining of mill bands, yet my Invention may be applied to the joining of other
bands, and to other like purposes.
Having now particularly described and ascertained the nature of the said Inven-

page_text: tion, and in general terms set forth in what manner the same is to be performed or
put in practice, I now proceed to further and particularly describe and ascertain in
what manner the same is to be performed or put in practice by reference to the
accompanying Drawings, that is to say :—
DESCRIPTION OF THE DRAWINGS.
Figure 1, view of one of the pieces of metal, shewing the prongs on same, and
the oblong slots.
Figure 2 shows the two pieces of metal which form the fastening before securing
the same.
Figure 3, view of the fastening in position, securing the leather or other band.
Figure 4, view of fastening with three prongs and corresponding slots.
In these Figures A are the sheets or pieces of metal; B, the oblong slots in same;
C, prongs; D and D¹, the two portions of band as fastened.
The action is as follows:-The pairs of holes are first cut or made in the over-
lapping ends of the band D, D¹, at the requisite distances apart; the two parts of
fasteing (Figure 2) are then placed under and above the said ends; the prongs C are
then passed through a pair of holes in the band D, D', and thence into the oblong
slots, as in Figure 2, and the two pieces pressed firmly against the band; then the
prongs Care pushed or forced down, and they lie flush or nearly so with the upper
and lower sides, as in Figures 3 and 4, firmly clenching and holding the ends D, D¹,
of the band, as shewn.
In order to carry my Invention into practical effect I recommend that punches of
the following construction be used for the purpose of making the holes in the
band-For making two holes the punch is formed with bifurcated cutter and guide
plate projecting from same, that is to say, the side view of the cutter end of this

Having now particularly described and ascertained the nature and object of the
said Invention, and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim the Invention of "Improvements in Fastenings
for Joining Mill Banding, and for other like Purposes," substantially as the same is
herein-before set forth and described by the words preceding the words " Description
of the Drawings."
In witness whereof, I, the said Samuel Andrews, have hereunto set my hand
and seal, this First day of February, in the year of our Lord One thousand
eight hundred and seventy-seven
