Description

@anni @twine JOHN A. WOOD, OF FAR ROOKAWAY, NEW YORK.`

Leners Patent No. 105,023, dated .my 5, 1870.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, JOHN A. Woon, of Far Rockaway, in the county of Queens and State of New York, have invented a new and useful Improvement in Hand Circular-sawing Machine; and that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference beingr had tothe accompanying drawing forming part of this specification.

The object of this invention is to furnish a simple and effective machine for sawing in wood-shops, and for `ioinerswork generally; and

It consists in the arrangement and combination of parts hereinafter described.

In the accompanying drawing- Figure 1 represents a top or plan view.

Figure 2 is a vertical section of fig.`1 on the linev a: x.

Figure 3 is a detail of the upper table.

Figure `d is a detail of the lower table.

Similar letters of reference indicate corresponding parts.

A is the frame by which the operating parts of the machine are supported. This frame is made of wood, and of any desired size and strength.

B is the driving-shaft, which extends across the frame, with a clank, C, on one end, for driving the machine, and a iiy-wheel, D, on the other end.

E is a gear-wheel on this shaft, which meshes into a pinion, F, on the saw-shaft G.

H is a fly-wheel ou the outer end of the saw-shaft.

I is the main table, for splitting or sawing boards or other. lumber. y

. Just above this table is an adjustable feed-roller, J, which is revolved by means of a band, K, on the conepnlleys L and M, as seen in iig. 1. Cone-pulleys are used so that the feed may be varied according to the thickness of the wood to be sawed.

In the middle of this feed-roller there is a section of it, N, iiuted or serrated, to give it a hold upon the board or wood to be sawed.

This feed-roller operates in connectionwith a loose I do hereby declare roller, 0, directly beneath, on which the board to be sawed rests. Y Y

P is the upper table, which rests on the lower one, and is, consequently, raised and lowered with it. This table is used for rch-ating', and for all the purposes to which it is a'dapted.

Both tables are provided with adjustable guides, 1t and S, as seen in the drawing.

The tables are raised and lowered, or adjusted, by means of double inclined planes, T and U, asseen in g. 2.

These inclined planes are moved lby the crank-v' screw V. l

The frame NV of the. lower table rests on the inclined planes;

The table is lowered by withdrawing the plane,as it descends-by its own gravity.

. Each table has rollers, X, at each epd ofthe tableframe W, which are. n a level with the tables over which the lumber to be sawed is fed. The upper table isreadily removed when not `Wanted for use.

The tables may be adjusted to cut any desireddepth, and the yfeed may be varied to suit any thickness of stun, or any degree of power.

' For slitting up boards or planks, and'preparing cabinet or joiners work, this machine will be found of the greatest advantage.

Having thus described my invention,

I 4claim as new and desire to secure by Letters Patent- 1. The -combination of the tables I and P and the inclined planes T and U in a machine for sawing, ar-

ranged and operating substantially as described.

2. The loose friction-roll O, placed in a verticallyadjustable table, P, combined with a iluted roll, N,all relatively arranged in a sawing-machine, to form an improved feeding device, adapted to different thickncssesof wood.

The' above specicution signed by me this 24th day of February, 1870.
