I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings in the County of Middlesex 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 :-
This invention consists of a machine for making nut fasteners, and similar articles,
which are of ierpentine form with eyes at the ends thereof, said machine embodying
means first, for converting a blank or piece of metal into serpentine form, and next,
producing the eyes on the end of the same.
In the accompanying drawing:
Figure 1 represents a top plan view of a machine embodying this invention for
making nut fasteners.
Figure 2 represents a side elevation thereof.
Figure 3 represents a horizontal section of a detached portion.
Figure 4 represents a horizontal section of a detached portion, and
Figure 5 represents a partial side elevation and partial vertical section of a detached
portion.
•
Similar letters of reference indicate corresponding parts in the several figures.
A represents the frame of the machine, and B represents a bed which is supported
on said frama

page_text: Rising from the bed and stationary thereon are two studs C, which extend vertically
and are separated a sufficient distance to permit the passage between them, of a blank,
or bar, or piece of iron, as is most clearly shown in Figure 3.
In the hed are segmental slots D, and below the same is a lever E, which is
pivotted to the frame and carries two pins or slots F, which, project upwardly through
the slots D, are parallel with the studs C, and, are adjustably connected with the lever
in a vertical direction, so that when their upper ends become worn or fractured, they
may be cut off and fresh parts presented in lien thereof.
G represents rotary shafts or spindles which are fitted in bosses or bearings H, the
latter being bolted or otherwise secured to the bed A, said shafts being of crank form
and carrying on their lower limbs fingers J, which are so disposed that when the
shafts G, are rotated, said fingers are brought into contact with ends of the blank or
piece of metal which is introduced between The studs C.
The fingers are adjustably connected with the limbs of the shafts G so as to
project from said limbs to greater or less extent, and the limbs of the shafts are
adjustably connected together by means of bolts, or screws, K, whereby the throw of
the lower limb of the crank shaft, and consequently the fingers J may be adjusted.
Connected with the shafts G are levers L, whereby said shafts may be operated, and
to said levers are attached laterally projecting toes M, which are adapted to abut
against stop pieces N, the latter being secured to supports 1', which are bolted or
otherwise fastened to the bed B, said pieces N being on opposite sides of the studs C,
and serving to limit the motions of the levers L.
Qrepresents a gauge which is adjustably connected with the bed B or adjacent
portion of the frame A; whereby the blank may be set true in position between the
studs C.
The operation of the apparatus is as follows:-
The lever E is moved so as to occupy a position at right angles to that shown in
Figure 1, and the blank is then placed on the bed between the studs C, it being
noticed that the studs F, are on opposite sides of the blank between the centre and
ends thereof, see Figure 3. The lever E is now returned to its first position, and as
the studs F bear against the blank, the central portion of the latter is bent in opposite
directions around the stud C, as shown by the dotted lines, Figure 3, thus producing
the body of the nut fastener.
The fever is now secured by a catch or fastening R, so as to remain immovable
during the subsequent operation, said catch being properly attached to the frame A.
The levers L, are now moved, and as the fingers J, bear against the ends of the
blank, the latter are bent around the studs F, thus forming the eyes on the ends of the
nut fastener.
The levers are returned to their first position, and the nut fastener removed from
the studs C, F, after which the lever E, is released and again advanced to a right-
angular position. Another blank is placed between the studs C and then subjected to
the operations described in the previous case.
The collars F, which connect the studs F, with the lever E, are laterally adjustable
by means of bolts E, whereby said studs may be set nearer to or further from each
other, and thus adjusted in relation to the studs C.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondents, I declare that what I claim is :-
First. Stationary studs in combination with studs which may be moved around
the same, and form the sepentine body of a nut fastener, substantially as described.
Second. Studs, in combination with fingers which may be moved around the same
and form the eyes of the fastener, substantially as described.
Third. Studs between which a blank may be fitted, movable studs which bend the
blank around the first named studs, and fingers which move around the second
named studs and form eyes on the ends of the blank, said parts being combined and
operating substantially as described.

page_text: Fourth. A bed formed with slots and provided with studs, a pivotted lever carrying
studs which project through said slots aside of the studs of the bed, and pivotted
levers carrying fingers which rotate around the studs, combined, and operating,
substantially as described.
Fifth. The levers L carrying the fingers J, and provided with toes M, in combina-
tion with the stops N, and supports P therofor, substantially as described.
Sixth. Studs for holding the blank, in combination with fingers attached to a crank
shaft, whereby said fingers are rotated around said stud, substantially as described.
Seventh. The studs F, adjustably connected with their supporting lever, and the
slotted bed with studs attached thereto, combined, and operating, substantially as, and
for the purpose, set forth.
