Sealed the 7th July 1874, and dated the 12th January 1874.

page_text: The means by which I propose to attain the said object of my present
Invention are as follows:-After cutting to the required size and shape
a sheet or plate, or sheets or plates of metal, leather, or other suitable
material intended to form part of an article, say a box; the joint,
joints, or seams of which it is intended to fasten together with rivets
I pierce, punch, or drill the parts at or near and along the respective
edges thereof intended to form the seam or joint at regular distances
by means of a press or other suitable machinery having a guide to
mark the required regular distances at which it is desired to place
the rivets; the sheets so pierced at their respective edges I then place
one over the other so that the holes in each sheet correspond; then I
put suitable rivets through each corresponding pair of holes in the two
pierced sheets, temporarily holding each rivet as it is passed through
the said holes on the side where the head of the rivet is to be formed
with a spring clip of sufficient strength to hold the rivet in its place,
and also to assist in holding the two edges of the sheets placed as already
described together.
The clips to hold the rivets may be made of steel or any other
suitable material, and may be of any convenient form and shape;
those I at present use are bowed similar to sheep shears, but with
flat ends. I now place the parts intended to form the joint or seam
with all the rivets in their respective holes and each held there by a
clip upon a mandrel or anvil having the surface thereof either flat
or shaped to correspond with the form of the article being made,
so as to allow the said rivets to rest thereupon; I then withdraw
all or any number of the clips, as may be convenient, the rivets being
now prevented from falling out by their resting on the mandrel or
anvil; I now clench or head all or any number of the said rivets in
succession, and thus finish the joint or seam.
These clips may also be advantageously used in the process of a
rivetting on the handles of coal. boxes, the ears on buckets, and in
numerous other similar cases.
It will be perceived, especially by a practical man, that by piercing
the plates or sheets intended to form such a joint or seam, as described,
it will facilitate the placing of the rivets, and that by holding a number a
of rivets in their places, and at the same time keeping together the
parts of sheets or plates intended to form a joint with my clips, it
will enable a workman speedily to do a large amount of rivetting,

page_text: whereby much time and labour will be saved, especially in the case
of rivetting at the bottom of a box or tank, and at the seams of stove
piping, where it is generally difficult to place and hold rivets:
Further, by using my improved rivetting clips, as herein described,
enables me to employ unskilled labour, or boys, or females for placing
the rivets previous to their being rivetted down, thereby further con-
siderably reducing the cost of the manufacture of such boxes, trunks,
and the like; in short, bringing rivetting into use where formerly it was
avoided on account of the extra cost of the labour involved.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Mohr in the Great Seal Patent Office on
the 10th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
MOHR, of Birmingham, in the County of Warwick, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of January, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Charles Mohr, Her special
license that I, the said Charles Mohr, my executors, administrators,
and assigns, or such others as I, the said Charles Mohr, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "A NEW OR IM-
PROVED METHOD OF RIVETTING THE JOINTS AND SEAMS OF DEED AND OTHER
BOXES, TRAVELLING TRUNKS, COAL VASES, AND SIMILAR ARTICLES," upon the
condition (amongst others) that I, the said Charles Mohr, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in. what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent

page_text: Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Charles Mohr, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement thereof, that is to say:-
This Invention has for its object to improve the method of rivetting
the corners, joints, and seams of boxes, travelling trunks, portmanteaus,
and similar articles where many small rivets are required or may be
used.
In order that my said Invention may be more clearly and more
fully understood, and be more readily performed, I now proceed to
explain the same with the aid of the accompanying Drawing, which
forms part of this Specification, reference being made thereto by the
numerals and letters marked thereon, and which reference applies to each
Figure of the said Drawing where the same index numerals and letters
appear.
Figure 1 is a perspective view of a bow-spring clip; Figure 2 is a
plan of the same shewing the way the clip holds the rivet in place;
Figure 3 is a plan view of a cylindrical spring clip which is in form
somewhat similar to a penholder; Figure 4 is a transverse section of the
same.
The plates a, b, whether of metal, leather, or other material, are
first cut to the required size and shape and then pierced, punched,
or drilled to form circular holes through the said plates at or near
and along the respective edges thereof (see Figure 2) at regular
distances by means of a press or other suitable machinery or appliance
having a guide to mark the required regular distances at which it is
desired to place the rivets; the plates a, b, so pierced I then place
one over the other, a suitable rivet c is then put through each corre-
sponding pair of holes in the said plates a, b, temporarily holding
each rivet as it is passed through the said holes on the side where
the head of the rivet is to be formed by a spring clip of sufficient
strength to hold the rivet in its place, which clips also assist in holding
the two plates of metal together as placed.
The said clips may be made of steel or
may be of any convenient form or shape.
other suitable material, and
The two kinds of clip d, e,

page_text: which I prefer to use are shewn in the Drawing; those, d, in Figures
1 and 2, are bowed similarly to sheep shears, but with flat ends, near
which is formed a hole d in which the rivet is held. The cylindrical
clip e is of more simple construction, having a curved mouth or entrance
at one end to guide the rivet into the small opening e¹ which runs
through the clip lengthwise, as shewn. The plates a, b, fitted with a
rivet in each pair of holes, and each rivet held there by a clip, are
placed upon a mandrel or anvil having the surface thereof either flat
or shaped to suit the form of the article being made or rivetted, so
that the rivets rest thereupon; I then withdraw the whole or any
portion of the clips, as may be most convenient, the rivets being now
prevented from falling out of the holes by their resting on the mandrel
or anvil, and then clench or head the whole or any number of the
rivets c in succession, and thus finish the joint or seam.
My improved rivetting clips may also be advantageously used in the
process of rivetting on the handles of coal boxes, the ears on buckets,
and in numerous other similar cases.
Any practical man will at once perceive that by piercing the plates
a, b, in the manner hercin-before described, it will much facilitate the
insertion of the rivets in the holes, and that by holding the whole or a
number of such rivets as thus placed, and at the same time keep
together the said plates as fixed and intended to be joined with my
said clips, an ordinary workman will be able speedily and efficiently
to do a large amount of rivetting, whereby much time and labour.
will be saved, especially in rivetting at the bottom of a box or trunk,
and the seams of stove and other piping where it is generally difficult
or inconvenient to insert and hold rivets.
Further, by using my said improved rivetting clips, and with the
method of procedure herein-before described, I am enabled to employ
unskilled labour, or even boys, or females for inserting the rivets
and fixing the clips thereto, thereby further considerably reducing the
cost of the manufacture of such boxes, trunks, and the like; in short,
causing rivetting to be practiced where it has hitherto been avoided in
consequence of the extra cost of the labour involved.
Having thus fully explained the nature of my said Invention, and
the method of performing the same, without confining myself to the
form or shape of the clips now illustrated, I claim as my Invention

page_text: and desire to secure by the before mentioned in part recited Letters
Patent, the method of rivetting and the use or application therein of a
spring clip to grasp and hold rivets in their places, substantially as herein
described and shewn in the Drawing.
In witness whereof, I, the said Charles Mohr, have hereunto 5
set my hand and seal, this Ninth day of July, in the year of our
Lord One thousand eight hundred and seventy-four.
