BENJAMIN F. APPLEGATE, OF NEWV ALBANY, INDIANA, ASSIGNOR TO HIM- SELF AND BENJAMIN F. LAGEL, OF SAME PLACE.

THRASHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 282,693, dated August 7, 1883.

\ Application filed April 30, 1888. (N model.)

To all whom it may concern.-

Be it known that I, BENJAMIN F. APPLE GATE, of New Albany, in the county of Floyd and State of Indiana, have invented certain new and useful Improvements in Thrashing- Machines, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the thrashing-cylinder and concave portion of the machine, the case therefor, and the adjuncts representing my invention. Fig. 2 is a detail of the clutch-regulating wheel and part of the cylinder and concave in section on the line of the cylinderfshaft. Fig. 3 is a transverse sec tion, on the line 00 w of Fig. 2, through the cylinder-shaft, with part of the case and the clutch-tripping mechanism in side elevation.

A thrashing-machine cylinder, a, is required to run at a high speed of about twelve hundred revolutions per minute, for which a high-speed belt is employed on asmall pulley, I), whereon the adhesion of the belt cannot besufficient to drive the cylinder positively without too much tension of the belt, and consequently too much friction of the journals for economical use of the power. Moreover, light tension of the belt is suflicient for driving the cylinder properly, except in the matter of the irregularities which occur by the slipping of the belt, which frequently happens from various causes, as the accumulation of dust on it, a slight shower of rain, slight overfeeding of the grain, and other causes, from which it will be seen that no matter how well the engine or other power may be regulated by a balance-wheel, governor, or other device, the cylinder will be sub-,

ject to changes which cannot be prevented by z', 011 which they are held by springs j, which have sufficient power to hold the upper teeth, 70, of the concave against the stress of the cylinder in the regular performance of its woflr, while the straw is free of any hard and solid substances; but the tension of the said springs is to be such that when, any such substances do accidentally enter with the straw the teeth will be, pressed down so as to raise arms 71, one of which has an extension, h, which is thereby made to raise a setting and tripping latch, Z, from the clutch-shifting lever m, so that the spring a will swing said lever, and thereby disconnect the clutch 0, by which the pulley b is connected to. the cylinder, and thus instantly stop the cylinder to allow the obstructing substance to be removed, and thus protect the machine and the attendant from harm. The tension of the springs j is to be adjusted by adjusting-screws p in the brackets q, to which said springs are connected. The setting and tripping latch Z is pivoted on a stud, s, projecting from the front of the thrashingmachine case, and the spring a, which shifts the lever m, is .also connected to said stud.

When the machine is cleared of the matters to be removed, the springs j will pull the arms h down and the teeth is up, and the latchl will fall and engage the clutch-lever m when it is shoved out to clutch the driving-pulley and the cylindertogether.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, in a thrashing-machine, of a yielding concave section, atrip-latch connected therewith, a thrashing-cylinder, the cylinder-shaft, the driving-pulley, the driving-belt, a clutch, and a spring-pressed shifting-lever which is set by the said trip-latch and released by the yielding section of the concave and said trip-latch, substantially as of said arms h having an extension, h, condescribed. nected with the trip-latch, substantially as de- 2. The combination of the cylinder a, the scribed. cylinder-shaft, the driving-pulley a clutch- BENJAMIN F. APPLEGATE. 5 connection, the pivoted yielding section 6 of Vitnesses:

the concave, arms h, rests i, springs j,'t1ip- R. O. KNOEFEL, latch Z, spring n, and the clutch-lcver m, one I BENJAMIN F. LAGEL.
