Letters Patent No. 114,159, dated April 25, 1871.

IMPROVEMENT IN BAND-CUTTlNG ATTACHMENTS FOR THRASHlNG-MACHINES.

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

To all whom it may concern Be it known that we, J OHN LEE, Jr., and JOHN LEE, Sr., of Duquoin, in the county of Perry and in the State of Illinois, have invented a certain new and useful Band-Gutter; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon. The nature of our invention consists in constructing a sheaf-band cutter for thrashing-machines by means of a double sickle-edged reversible'circular saw or knife set on a shaft at right angles to an adjustable spring bottom or platform, on which the sheaf is cut, the saw or knife to pass through a slot made for that purpose in the spring bottom when it is depressed to out the band; a foot-treadle with ratchet to depress and secure the spring bottom while cutting; a guard or cover on the under side of the spring bottom to shield the saw or knife when not in use; an arm or breast-guard and a skeleton frame to serve as a bearing for the spring bottom; all in a suitable frame or box, two sides of which serve as bearings for the saw-shaft, as will hereinafter more freely appear.

To enable others skilled in the art to make and use our invention, we will now proceed more fully to describe its construction and operation.

In the drawing Figure 1 is a perspective view of our invention, one corner of the spring bottom broken off to show the band-pulley of the sawshaft and the skeleton frame which serves as a bearing for the spring bottom, and

Figure 2 is a longitudinal vertical section about the center of the machine.

A is the frame.

B is the sheaf-platform or adjustable spring bottom, secured at its rear end a to the frame A.

This platform B has side guards, b, to prevent the sheaf from falling off, as shown in fig. 1.

This platform may be of metalor wood, but. it must be yielding or elastic, so as to spring or bend down over the skeleton frame 0; which is-under the platform B, when the foot-treadlc D, with rod cl, 2, connecting platform B, and treadle D is pressed down from its position shown in fig. 2 to the position it holds in fig. l.

A slot, 0, is provided in platform B, through which the saw or knife E may project when the platform B is depressed, as in fig. 1, for the purpose of cutting a band.

A semicircular guard or band, F, (sec fig. 2,) is secured to the under side of the platform B and The hands need not touch the platform to depress or rest upon it, as the foot-treadle D can be used to depress the platform, and the hands, arms, or breast can rest on the rod or guard G.

The, double sickle-edged reversible-circular saw or knife E is fitted on itsshaft e, which has hearings in the sides of the frame A, with a pulley, P, on one-of its outer ends, through means of which the necessary motion can be communicated to the saw E.

We prefer this saw, as one side will be sharpened to a desirable extent while the other side is in use.

The saw is placed midway of the shafts so that it will be immediately below the slot 0 in the spring bottom B, and when the spring bottom B is not depressed the saw will be out of sight; and when platform B is depressed only so much of the saw will project above the platform as'will be necessary to cut the sheaf-band.

Our machine having been constructed as above set forth, and then properly connected with a thrashingmachine, and a band uniting the thrashers power to the pulley P of shaft e put on, the saw E is set in motion; the operator having placed'a sheaf of grain on the adjustable spring platform B, with the band binding the sheaf across the slot 0, the apparatus is ready for operation.

The operator, with his hands or arms resting on the arm-guard Gr, places his foot on treadle D and forces it down from the position shown in fig. 2 to the position shown in fig. 1, carrying the connectingrod (1 and the sheaf-platform B with it, and then fastening the treadle D in ratchet or catch f, as rep-- resented in fig. 1.

The sheaf-platform B, as it is depressed, allows the band of the sheaf to come in contact with the circular saw E, and the hand is cut. The operator may then, to avoidall risk, undo the treadlc D and permit the sheaf-platibrm to rise before he feeds the shcafinto the thrasher.

Our invention, thus constructed and thus operated, will effectually overcome the great danger attending the feeding of thrashing-machines, .which, as ordinarily constructed, have the cutters exposed or uninclosed on all sides during the whole operation of handcut-tin g. p

A hand-lever may be used instead of the trcadle D.

Having thus fully described our invention,
