Letters Patent No. 107,675,'dated September 27, 1870.
IMPROV-EMENT IN MACHINES FOR SAWING MARBLE.
T heSchedule referred to in these Letters Patent and making part of the same.
To all whom. 'it may concern l Be it known that we, JAMES Faiincn and J Ames l M.STEPHENSON,`of 1?endletoi|, in the county of Madisonand State of Indiana, have invented certain new .i andusefnl Improvements in Marble-Saws; and we `-do hereby declare that the following is a full, clear,`
and exact description thereof', reference beinghad to the accompanying drawingiand to the letters of' reference marked thereon, which form a part of this In theaccompanyingdrawing-4l` i Figure 1- is a sidewiewvof our` improved machine for sawing marble. Figure 2 is aplan of the same. Figure is an"endvien".l
Our ini-'entionor improvement in machines for sawor more saws, consists- First, in a peculiar arrangement vand construction for vapplying the power ormoving the pitmen .inf the Second, in adjustable saw-g`uides on' sliding'` flames.
\ f Upon any suitable frame, A, is placed a horizontal -v shaft,- B, carrying two or more eccentrics,`0, which are adjustable upon 'the shaft lB,'in order to set the `lhe sameshaft carries a cani, 1), working `against two rollers, E, by Whichmeans the-shaft B,1as it rewolves',l is moved endwise with areciprocating motion,
`so as always to bringthe draft of 'each pitinan,M, on
a line with its saw, N.
The distance whichtheV shaft is moved by this. cam
`must-be varied according tothe dilerent angles at which the two saws are set' foi sawing different tapers,
and this variation maybe produced by different cams, or by making. the cam adjustable.
-Both ends of the saws are directed by adjustable 'saw-guides F, whiclrareheld i n place, by .screws G, in the slotsV H, and may be moved to the right or left, ,4
at4 pleasure. V
These guides are attached to the adj nstable frames I, which may be raised orlowered by means of cords J, windlass K, and ratchet L, or by other 'suitable4 means. 4
In place oi' the above eccentrios cranks may be ein-- ployechand other small changes may be made, without departing from our invention, so long as the machine is substantially. thensame.
Having described our invention, We claimf 1. The shaft B, when provided with areoiprocating end-play, in combination with two or more saws, substantially in` the manner and for the purposes setforth.- y l n 2. The combination ofthe cani 1), shaft B, and pulleys E,"substantially inthe manner and `for the purposes set forth. i
3. The adjustable saw-guides F, in combination with the frames 1 and saws, substantially as set forth..
In testimony that we claim the foregoing as our own, we aix our signatures in presence of' two witnesses.
' JAMES E.' FRENCH.
i JAMES.`M. STEPHENSON.
Witnesses:
ANDREW K.. Roonnnnmnn, CHARLES H. McCann'.
A Our machine maybe used for an ordinary'gang'- fsaw, it' desired. 1g marble in taper or Obelisk-finan, bythe use of two
