PROVISIONAL SPECIFICATION.
Improvements in Letter or other Files and in the Manufacture of
the same.
I, HARRY LEWIS LLOYD, of the Firm of M. A. Lloyd & Son, of 47, Princip
Street, Birmingham, in the County of Warwick, Manufacturers, do hereby
declare the nature of my said invention to be as follows:-
My invention has for its object improvements in letter or other files and in
the manufacture of the same and has special reference to the mode and means
of securing or attaching the spring or other clip to such files so as to enable the
said clips to be easily and readily attached or detached for storing or packing
purposes.
In carrying my invention into practice I form a base piece from thin sheet
steel or other metal having at its upper end or head four or more prongs or pro-
jections. The lower portion of this base piece is preferably formed taper and
these tapered sides are turned up and then over so as to form a taper groove or
channel. The extreme end of the tapered portion is also provided with a prong
or prongs or projecting piece or pieces. This base piece is then attached or
fixed to the ordinary back portion of the letter file by passing two or more
of the prongs on the head or upper end of the base piece and the prong or prongs
on the lower end through slots formed in the back portion of the file and then
turning or flattening down these prongs on the underside. Or I may rivet this
base piece to the back portion of the file or secure it by eyelets clips
or in any other
convenient manner. The spring or other clip is formed with the usual loop at its
upper end and at or near on either side of the base of this loop I form an ear
or projection. The lower portion of this clip is formed taper the sides being
also preferably formed V shape and this lower portion slides into the taper
groove or channel in the base piece. Two or more of the prongs on the upper
end of the base piece are then turned over onto the ears or projection on the
clip by this means it will be seen that the said clip can be readily and securely
attached to the base piece. It will thus be seen that as the clip can be so readily
attached to the file they may be packed or stored separately there-by economising
space.
In some cases I may form the groove or channel in the base piece straight and
the lower portion of the clip straight also, stops being provided at the lower ends
of the channel or groove so as to prevent the clip from sliding out. Or a pro-
jection or projections may be formed on the underside of the clip and slide into
a groove or grooves formed in the base piece. Or I may dispense with the base
piece and form lips or projections on the base of the clip itself which lips or pro-
jections pass through slots or openings formed in the back portion of the file the

back portion of the file.

Improvements in Letter or other Files and in the Manufacture of
the same.
I, HARRY LEWIS LLOYD, of M. A. Lloyd and Son, of 47, Princip Street, Bir-
mingham, in the County of Warwick, Manufacturers, 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 has for its object improvements in letter or other files and in
the manufacture of the same and has special reference to the mode and means
of securing or attaching the spring or other clip to such files so as to enable the
said clips to be easily and readily attached or detached for storing or packing
purposes.
In carrying my invention into practice I form a base piece from thin sheet
steel or other metal having at its upper end or head four or more prongs or pro-
jections. The lower portion of this base piece is preferably formed taper and
these tapered sides are turned up and then over so as to form a taper groove or
channel. The extreme end of the tapered portion is also provided with a prong
or prongs or projecting piece or pieces. This base piece is then attached or
fixed to the ordinary back portion of the letter file by passing two or more
of the prongs on the head or upper end of the base piece and the prong or prongs
on the lower end through slots formed in the back portion of the file and then
turning or flattening down these prongs on the underside. Or I may rivet this
base piece to the back portion of the file or secure it by eyelets clips or in any
other convenient manner. The spring or other clip is formed with the usual loop
at its upper end and at or near on either side of the base of this loop I form an ear
or projection. The lower portion of this clip is formed taper the sides being
also preferably formed V shaped and this lower portion slides into the taper
groove or channel in the base piece. Two or more of the prongs on the upper
end of the base piece are then turned over onto the cars or projection on the
clip by this means it will be seen that the said clip can be readily and securely
attached to the base piece. It will thus be seen that as the clip can be so readily
attached to the file they may be packed og stored separately thereby economising
space.
In some cases I may form the groove or channel in the base piece straight and
the lower portion of the clip straight also, stops being provided at the lower ends
of the channel or groove so as to prevent the clip from sliding out.
Or a pro-
jection or projections may be formed on the underside of the clip and slide into
a groove or grooves formed in the base piece. Or I may dispense with the base
piece and form lips or projections on the base of the clip itself which lips or pro-

page_text: jections pass through slots or openings formed in the back portion of the file the
said lips or projections being then turned down thereby securing the clip to the
back portion of the file.
In order that my invention may be more clearly understood and easily carried
info practical effect I have appended hereunto two double sized sheets of drawings
upon which I have illustrated examples of my letter or other files.
Figure 1 is a plan view of a portion of a file with my clip attached thereto.
Figure 2 is an inverted plan view of Figure 1.
Figure 3 is a cross sectional view taken on the line a-y of Figure 1.
Figure 4 is a plan view of the base piece or portion to which the clip is attached.
Figure 5 is a plan view of a modified form of base piece.
Figure 6 is a plan view of a portion of the clip.
Figure 7 is a side view of a modified form of my clip.
Figure 8 is a plan view shewing a portion of file suitable for fixing the clip to
as shewn at Figure 7.
Figure 9 is an inverted plan view of Figure 8 with the clip attached.
Figure 10 is a cross sectional view taken on the line 1-2 of Figure 9.
In carrying my invention into practice I form the base piece B or portion to
which the clip A is attached preferably by stamping or pressing from thin sheet
steel or other metal with four or more prongs 61 62 63 and 6 at the upper end or
head as shewn at Figure 4. The lower part 66 or portion below this head is
formed taper and is notched under the neck of the head at 67 so as to allow the
sides or edges 68 to be turned up and then slightly over thereby formed the
tapering groove or channel 6. The extreme end of the tapered part b6 is pro-
vided with the prong or projecting piece 610 or prongs or prejecting pieces.
This base piece B is then attached to the back portion D) of the ordinary body
portion of the file by turning the prongs 2 and 3 on the head 65 (when four
prongs are used) over the upper edge of the back portion D and passing the
prong on the end of the taper part 66 through the slot d formed in the back
and then flattening them down on the underside afterwards as clearly shewn at
Figure 2. Or the base piece B may be riveted or secured by eyelets clips or in
any other convenient manner to the body portion of the file.
The spring or other clip-A which is provided with the usual loop a¹ at its upper
end is formed at or near the base on either side of this loop with the cars or
projections and the lower portion or body at is formed with a taper towards
the end with the sides preferably formed V shape in cross section so as to slide
into the taper groove 9 of the base B in which it is secured by the prongs band b
being turned over onto the ears a² and a respectively or their equivalents as clearly
shewn at Figure 1. It will be seen that by this means the clip A can be readily
and securely attached to the base piece B thus enabling the clips and the body
portion of the files to be packed or stored separately thereby greatly economising
space which will be found of great advantage where warehouse room is limited.
In some cases I may form the groove or channel in the base B straight and
the portion of the clip A which slides therein also, the stops 612 being provided
at the lower end of the channel or groove so as to prevent the clip from sliding
out as clearly shewn at Figure 5. Or a groove or grooves may be formed in the
channel 6 of the base piece into which a projection or projections on the under-
side of the clip fit the ends of the grooves forming stops for preventing the clip
from sliding out. Instead of having two central prongs at the upper end 65 of
the base piece I may have only one as shewn at Figure 5.
At Figures 7, 8, 9 and 10 I have shewn a modified form of my file. In this
case I dispense with the base piece B and form the projections or prongs a on the
underside of the clip A as clearly shewn at Figure 7. These projections or prongs
pass through the slots or openings formed in the back D of the body portion
of the file as shewn at Figure 8 the said projections or prongs being then turned
down thereby securing the clip in position as clearly shewn at Figures 9 and 10.

page_text: 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
I claim is:-
:-
CLAIMS.
First: The improvements in letter or other files and in the manufacture of
the same consisting essentially in making the clip or part such as A detachable
from the body portion or part D so that the said parts may be packed or stored
separately in the manner and for the purpose substantially as herein set forth
and as shewn upon the accompanying sheets of drawings.
Second: In letter or other files connecting the clip or part such as A to the
body portion or part 1 by attaching or fixing to the part D a base piece such
as B having a straight or tapering groove or channel into which the part A fits
or slides the said part A being held therein by turning over the prongs or pro-
jections 6 and 6 or their equivalents on to the ears or projections a² and a³ or
their equivalents in the manner and for the purpose substantially as herein set
forth and as shewn upon the accompanying sheets of drawings by Figures 1 to 6
inclusive.
Third: In letter or other files attaching the clip or part such as A to the body
portion or part 1 by forming two or more prongs or projections such as a on
the underside of the said part A which prongs or projections pass through slots
formed in the part D in the manner and for the purpose substantially as herein
set forth and as shewn upon the accompanying sheets of drawings by Figures 7
to 10 inclusive.
