IMPROVEMENT IN FELLOE-SAWINGMACHINES.

Hin- The Schedule referred to in `these Letters Patent and making part cf the same.

Be it known that I, JOHN RICE, of Bloomington, in the county of Monroe, and State of Indiana, have invented new and useful Improvements in sawing-Machines ;4 and I do hereby declare. that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to an improved machine for sawing wagon-felices, chair-tops, or other similar articles, and consists in the construction and arrangement of the various parts, and their combination with each other.

The details ofconstru'ction, and manner of operation, will be fully described hereinafter.

In the drawings-.-

Figure l represents a perspective view;

Figure 2, a side elevation; and

Figure 3, a plan view of my improved machine.

To enable those 'skilled in the art to which my invention appertains, to make and use the same, I will now proceed to describe its construction and operation A A represent the main frame ofthe machine, which may be constructed in any proper manner, and from which rise the standards B 'B,'holding the saw-frame.

C represents the main shaft, upon which is placed the ily-wheel C, and pulley C2, by means of which latter the power is communicated to the machine.

The shaft C is provided with a crank, G3, to which is attached the lower end of the pitman D,which op-. erates the saw-gate E.

Within the latter are the concave saws E E', which are located at a suitable distance apart.

H represents a lever, pivoted to one of the standards B, which is connected at one end to the saw-gate E, by means of the bar e, and at the other to the rod h, which latter is attached to the elbow-lever I, pivoted to a standard attached to the side of the frame, as shown.

J represents a bar, provided at 011e end with a bent metal shoe, which rests upon the ratchet-wheel K, and which is attached at the other end to the elbow-lever I.

By means of holes in the latter, the bar J can be adjusted so as to move a longer or shorter distance, as may be desired. KT represents apawhby means of which the ratchetwheel Kis either attached directly to a bevel-gear wheel, L', or to its shaft, L, as may be desired.

The gear-wheel L engages with the'gear-wheel M, attached to perpendicular shaft M', as shown, upon which latter is a pulley, round which passes a belt, or cord, which also passes about the circular extensiontable N, in a groove arranged for that purpose.

L2 represents a hand-wheel, upon the end of shaft L, by means of which it may be revolved without moving the saw.

The circular extension-table N is supported by the perpendicular shaft N', which turns`insuitable bearings below.

This latter is constructed wththe Y-shaped pieces n u, which may be drawn outward when desired to increase the size of the latter.

O O represent clamps, which are secured to the table by means of the screws O'.

P represents the matelialto be sawed.

From this description, the operation of my machine will bereadily understood.

The material having been properly secured to the table, the machine is set in motion.

At each movement of the saws, 'the table is alsol turned by means lofthe connection described, so thematerial is properly kept up to the saw.

As the saws are concave in form, they cannot bind up the material, and therefore work with great ease. W'hen it is desired to turn the table without operating the saws, the hand-wheel Lz is used.

By adjusting the barJ to traverse a longer or shorter distance, the material may be fed' faster or slower, as may be desired.

' This machine has proved itself to -be exceedingly efiicieut in turning out work rapidly, it being capable of' sawing from fifteen hundred to two thousand felloes per.

day. Having thus fully described my invention,

Vhat I claim, and desire to secure by Letters Pat,- ent of the United States, is- The sawing-machine described, consisting of the frame A, standardsB, shaft C, pitman D, sawgate E, saws E', levers H and I, bar J, ratchet-wheel K, shaft, L, gear-wheels Ll M, and extension-table N, the whole being. combined and operated in the manner and for the purposeset forth.

This specicationsigned and witnessed, this 28th'day of September, 1868.

. JOHN RICE. Witnesses:

WM. M. TATE, HENRY FELLows.
