BENN F. DUNKLEE, OF CONCORD, NEW HAMPSHIRE.
IMPROVEMENT lN CIRCULAR-SAW BENCHES.
Specification forming part of Letters Patent No. 112,908, dated March 21, 1871.
I, BENN F. DUNKLEE, of Concord, in the county of Merrimack and State of New Hampshire, have invented certain Improvements in Adj ustable Circular-Saw Benches, of which the following is a specification:
Nature and Object of the Dwention.
Description of the Accompanying Drawing.
Figure 1 is a vertical transverse section of a machine embodying my invention. Fig. 2 is a perspective view of the same, taken from the back of the machine.
General Description.
A A is the frame of the saw-bench, with the bearings of the counter-shaft cast a part of the same. Bis the counter-shaft. O is the adjustable swingframe, which is hung on the bearings of the counter-shaft. The upper end of the swing-frame G carries the bearings of the saw-arbor, thereby securing a uniform tension of the belt, regardless of the raising or depressing of the saw.
Near the upper end of the frame 0 is an opening, D, in which is pivoted a nut, E, by two set-screws, F F, which allow the screw G to oscillate in raising and lowering the upper end of the swing-frame O.
On the screw G is a gear, E, that is rotated by the worm- I on the shaft of the hand-wheel J, running in bearings of hand-frame K, the lower end of which is pivoted to the cross-bar L. The lower end of the screw G bears upon and passes through the hand-frame, and is secured by a nut underneath.
Claim.
operating in the manner and for the purpose I shown and described.
BENN F. DUNKLEE.
