I, FRANS ZEINWOLDT, of Bodafors, Sandsjo, in the Kingdom of Sweden, Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
'
This invention refers to improvements in or relating to bandsaws.
The bandsaws hitherto constructed have the disadvantage of being shaky on
account of the heaviness of the upper part.
The object of this invention is to do away with the said disadvantage and also
to get rid of the spring or rubber buffer necessary in the present band-saws.
This invention consists in providing a light and at the same time elastic bow or
frame for carrying the saw-driving wheels. The bow or frame is made out of
strips of wood placed together side-ways one behind another..
The accompanying drawing shows a side-view of a band-saw constructed
according to this invention.
a represents the bow or frame carrying the saw-driving wheels b and the
bearings d for the same. Said bow is made of strips of wood e, e bent sideways to
the proper shape and laid together one outside the other as shown in the drawing,
and fastened together by any suitable means, such as rivets, glue or the like.
Since it is the lower wheel that draws the saw and the purpose of the upper wheel
only is to keep straight that part of the saw that is above the wood that is to be
sawed, a band-saw constructed in the aforesaid manner will be steady enough, at
the same time balances or buffers are unnecessary, the bow being elastic enough to
keep the saw-blades straight.

Referring to the drawing filed with the Provisional Specification which shows a

a represents the bow or frame carrying the saw-driving wheels b and the

the proper shape and laid together one outside the other as shewn in the drawing,

the same time balances or buffers are unnecessary, the bow being elastic enough to
keep the saw-blade straight.
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:
In a band-saw the bow or frame carrying the saw driving wheels composed of
strips of wood, substantially as and for the purpose set forth.
