IRA REYNOLDS, OF BELLEFONTAINE, OHIO.

STRAW-GUTTER.

Specification of Letters Patent No. 81,328, dated February 5, 1861.

T 0 all whom it may concern:

Be it known that I, IRA REYNOLDS, of Bellefontaine, in the county of Logan and State of Ohio, have invented new and useful ln'iprovements in Straw and Stalk Cutters; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which I Figure 1, is a. perspective view; Fig. 2, is a transverse section; Fig. 3 is a longitudinal elevation, with some of the several parts detached; Fig. 4: is a birds-eye view, showing the attachment of the gearing, with its several bearings and connections; Fig. 5 is a transverse section showing the action of the crank upon the rock shaft of the feed motion; Fig. 6 is a. section of the feed box detached; Fig. 7 is a plan of the adjustable plate; Fig. 8 is a side elevation of the boxing for the feed rollers, and fastening for the feed box; Fig. 9 is a perspective of the same.

A is the frame work; B is feed box; C is the cutter blade; D is the adjustable plate; E is the boxing and fastening for the feed box; F is the arm to which the blade is attached; G is the pitman connecting the arm to the crank; H is the crank connecting with the pitman; I is the hand crank; J is the ratchet wheel; K is the rock shaft of the feed motion; L is the rod on which the blade works; M is the brace holding the feed box; 1 is the balance wheel; 0 is the driving gear wheel; P is the pinion; R is the screw rod,regulating the feed motion; S is a staple passing over and holding the ratchet hands in place; T is the ratchet hand; U is the spring holding down the upper feed roller; V is the boxing; V is the shafting; X is the friction roller; Y is the strap and hooks, which secures the feed box to the machine; Z is the handle.

I construct my machine of suitable timber say 2 by 3 inches square and about ll; feet long with girders and cross ties which make it about 14 by 21 inches square, with curved bottom pieces, so as to make it stand firm upon the floor. 7,

My main driving wheel 0, is about 12 inches in diameter and about 2?; diameters of the pinion P. On the end of the pinion shaft is a crank H, 25} inches long which is connected to the arm F by means of the pitman G, as seen in Figs. 1 and 2. This crank shaft is arranged between the arm F, and blade C for the purpose of making as direct an action upon the blade as possible with so short a crank and producing a direct action upon the rock shaft K of the feed motion, which is produced by the wrist of the crank acting directly upon the rock shaft, the wrist being supplied with a friction roller 2 inches in diameter and of an inch thick, to take off the friction; this roller is seen at X, Figs. 1, 2, a and 5.

The rock shaft of the feed motion is made of cast iron about 1 by 1-1- inches in diameter and of suitable length for the width of the machine, and is slotted as seen at a a a, Fig. 1, for the purpose of admitting the ratchet hands T, also for the purpose of supplying the center with india rubber or some other pliable substance, so as to take off the jar and consequent strain and noise in operating the machine; this rubber extends as far as the friction roller works upon the rock shaft, and is about thick and is shown at Z), Figs. 1 and 2.

The arm F may be made of wrought or cast iron, about by is and for a 10 inch machine about 20 inches long and curved as seen in Figs. 1 and 2 so as to admit of greater length of pitman. It is slotted at the end where it is secured to the blade, sufficient-1y to admit the blade to work in the slot, as seen at m Fig. i.

The blade is made of cast steel about wide by 26 inches long, or of suitable length for the width of the machine, and is curved at the lower end as seen at (4 Figs. 1 and 2 suflicient to bring the rod L to cross the blade at about :1- its length, as seen in Figs. 1 and 2 thereby bringing a leverage upon the edge of the blade, and securing an easy and certain mode of adjusting the edge of the blade to the mouth piece A Fig. 2, which is done by means of the adjustable plate D Fig. 7, which is made triangular of cast iron, and extends about 8 inches from the frame of the machine, and is about thick and i inches wide where it is secured to the frame work by means of a pivot at n Fig. 7, and by a temper screw at a Fig. 7. The rod passes through and is secured to this plate as seen at 72, Figs. 1, 2, 3, 4 and 7. It will readily be seen that by the adjustability of this plate,

the blade may be readily changed to or from the mouth piece A Fig. 2, it being so perforatcd that the rod L readily passes through it, as seen at /L Fig. 1.

The rod is made of 5% iron and secured to the inside of the frame as seen at e c Fig. 4 and by a screw and nut to the adjustable plate, as seen at 0 0 Figs, 1 and 2.

The boxing for the feed rollers and fastening for the feed box is made of cast iron and so constructed as to form a simple and suflicient box for the lower roller and an efficient sliding slotted box for the upper roller. This box is constructed with bearings for the journals as seen at u u Figs. 8 and 9 also a slot for the spring U which presses upon the journals of the upper roller, it also forms a complete fastening for the feed box which is supplied with strap hooks, which are placed in that portion of the box extending outward as seen at 2' Fig. 9 and the feed box being raised up at the rear end brings the upper portion of the sides under the notch at 5, thus securing and holding it firmly in place and against the action of ,the springs as they are pressed upward by the feed rollers. The brace 11, Fig. 1 holding the rear portion in place.

The spring U Fig. 6 is made of wire and coiled so as to become sufficiently elastic to admit the upper roller to move upward in changing the quantity of feed, and passes in above the journal through the slot at Z Fig. 9, and is secured to the box at f Fig. 6 by means of a screw, and at f f by being bent and driven into the box.

The pitman is made of cast iron about 9 inches long and 1 by 1!; inches diameter with a hole for the wrist of the crank and slotted at the top so as to admit the arm F to pass through it, as seen at 9 Fig. 1.

The temper screw 70 is made of small iron and passes under the rock shaft of the feed motion, as seen at (Z cl Figs. 2 and 5 and is held in place by a small plate 4 4. Figs. 1, 2 and 5 and is regulated by means of a nut 3 at the top, which raises or lowers the rock shaft by loosening or tightening the nut. The arm F in its movement is held in place by means of a rod 00 w m Fig. 3.

All other portions of the machine including the feed box, shafting, boxes and all of the several fastenings are made in the usual manner and secured by means of bolts, nuts and screws as seen in the several portions of the drawings.

It will readily be seen by the foregoing description, that by turning the crank I an immediate and rapid sliding angular motion is given to the cutting blade, which with the force of the balance wheel, makes the operation very easy, and the wrist of the crank at the same time acting directly upon the rock shaft of the feed motion, produces a positive action of the feed rollers, all of which is secured by the arrangement of the crank between the arm and cutting blade. The ease of a rapid motion of the blade is apparent from the fact that every weight and obstruction is removed from it by giving it the peculiar curved shape atthe lower end and guiding its motion by the rod, which being adjustable, places the machine and its operations entirely under the control of the operator.

Having described the nature and operation of my invention, I wish to say that I do not desire to claim, and therefore disclaim the invention of gear wheels, balance wheels, cranks, rock shafts, feed rollers, cutter blades, rods and slides, but

What I therefore do claim as my invention and desire to secure by Letters Patent 1s 1. The arrangement of the crank between the arm F and blade C, with the rock shaft K and feed motion as and for the purposes described.

2. Constructing the journal box E, in such a manner as to form the box for the lower roller and the sliding or slotted box for the upper feed roller, with slot for spring,'and fastening for the feed box as seen and represented in the accompanying drawings and specification.

3. The combination of the adjustable plate D, and the rod L, when constructed and operating as and for the purposes described.

IRA REYNOLDS.
