PROVISIONAL SPECIFICATION.
A Combined Tongs and Hand Iron Saw Frame.
ARTHUR ALBERT TATTERSALL 13 and 15 Water Street Accrington, Lancashire and
2 Hermitage Walk, Frankwell Shrewsbury in the County of Shropshire, Draughtsman
and Practical Engineer, do hereby declare the nature of this invention to be as
follows:-
This Invention relates to the combination of my Improved Alligator Tong and
Hand Iron Saw Frame.
The Alligator Tong has one moveable and one fixed jaw, for gripping various sizes
of tubing, nuts and the like.
To the fixed jaw and handle, I secure, in the most convenient manner, a saw,
for sawing or cutting metals, such as the ends of bolts, keys, set screws, brasses
and the like.
The combination of my improved Alligator Tong and saw frame, will save the
expense of separate tools, and answer the purpose of both.
Secured to the fixed jaw by a rivet, pin, or stud, works the moveable jaw.
The end of this moveable jaw is prolonged, and against this prolongation and
handle of fixed jaw, works a sliding wedge, setscrew, or other suitable mechanism,
held, secured, or worked, in the most convenient manner, for opening or closing the
jaw to any desired size.
One of the jaws must be roughened and the other smooth.
In the action of gripping, the smooth edge welges the articles against the
roughened edge, thus, the greater the pull on the handle, and the tighter the article
operated on becomes wedged or gripped in the jaws, the roughened edge preventing
the article from slipping.
The setscrew can be screwed into the handle of the fixed jaw, or through the pro-
longation of the moveable jaw.
In the handle of the fixed jaw, I make a slot, groove, or recess, into which I secure
the saw for metals, by any suitable means.
The handle of the fixed jaw securing saw, I make of any desired shape.
The Alligator Tong and Hand Iron saw frame can be made and used separately
if desired.

A Combined Tongs and Hand Iron Saw Frame.
ARTHUR ALBERT TATTERSALL 13 & 15 Water Street, Accrington, in the county of
Lancashire, and 39, Havelock Street, Stoke-on-Trent, in the county of Staffordshire,
Draughtsman and Practical Engineer, 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 relates to the combination of my improved Alligator Tong and Hand
Iron saw frame.
And consists in making and using the Alligator Tong and Hand Iron saw-frame in
combination, or separately if desired.
Figs. I & II are elevation and plan of one modification of my Improved Alligator
Tong and Hand Iron saw frame.
In Fig. 1. A a is the fixed jaw and handle. Into the handle A, I make a slot,
groove, or recess, wherein I fix the saw-blade B by set-screws or small bolts C,
which will allow of saw-blade B being inserted or removed as desired.

page_text: The moveable jaw D with its prolongation "d" works on rivet E, in handle A.
Through handle A or prolongation "d" works setscrew E, which raises or lowers
moveable jaw D, thus opening or closing the Alligator jaw, to allow various sizes of
tubing, nuts and the like being gripped in it.
Figs. III and IV are elevation and plan of another modification of the same
invention, wherein I make the handle “a”,slightly cranked or bent, to allow of
clearance in the material being sawn. In each end of the cranked or bent
handle"
a," I make a slot, groove, or recess, wherein I fix saw-blade B, which can
be inserted or removed as desired, by set-screws or small bolts C.
The setscrews are inclined at opposite angles to each other, for putting tension
on the saw-blade B.
"
a.
The moveable jaw D with its prolongation "d" works on rivet E, in handle "
Between prolongation "d" and handle "a" works the sliding wedge G, on
screw-washer J.
The screw-washer I is held by rivet E.
The sliding wedge G can be actuated by a nut working on screw-washer I, if
desired.
When the sliding wedge G advances towards the rivet E, the Alligator jaw F
becomes closed; when it advances from rivet E, the jaw is opened to admit various
sizes of tubing, nuts and the like being gripped.
One of the Alligator jaws must be roughened, and the other smoothed, the roughened
jaw being nicely tempered.
In the action of gripping, the smooth edge, wedges the article against the roughened
edge; thus, the greater the pull on the handle, and the tighter the article operated
on becomes wedged or gripped in the jaws F, the roughened edge preventing the
article from slipping.
In the action of the saw, the handle or framework A a, keeps the saw B so strong
and rigid, that it works with greater power, and does not break so easily as the saw-
blade in the ordinary bow-frame with tension-screws, and is more easily secured or
removed.
The Alligator Tong and Hand Iron saw-frame can be made and used separately
if desired.
The saw frame would have a prong or taper end, onto which would be secured a
file handle, and the handle of the Alligator Tong would be made plain.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. The combination and arrangement of parts forming my improved Alligator
Tong and Hand Iron saw frame, as herein set forth, and shewn in the Figs. I
and II.
II. The combination and arrangement of parts forming my improved Alligator
Tong and Hand Iron saw frame, as herein set forth and shewn in the drawings in
Figs. II and IV.
III. The separate making and using of my improved Alligator Tong and Hand
Iron saw frame as herein set forth and described.
IV. The movement of the moveable jaw on rivet or pin E of Alligator Tong.
Dated, this 5th day of December 1889.
