IIMPROV EM ENT IN H ARVESTER-RAKES.

Specification forming part of Letters Patent No. 56,696, dated July 31, 1866.

I To all whom it may concern:

hereby declare that the following is a full and complete description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a plan view. Fig. 2 is a view of the under side. Fig. 31s a view of one end.

- is secured to them by set-screws d.

Fig. 4 is a view of the other end with the platform in a difi'erent position. Fig. 5 is a rear view. I

Like letters of reference refer to like parts in the different views.

A is a platform, with side pieces, 11, secured to it. C is a shaft, extendin g lengthwise of the platform at the rear, that passes through journal boxes or bearings d, attached to the under side of the platform, as seen in Fig. 2, and E and F are arms securely attached to the innerand outer shoes, or to the ends of the cutter-bar, through the rear ends 'of which the shaft 0 passes. Extending along the front side of the platform the length of the cutter-bar is a roller, H, to which canvas-cloth or other suitable material is attached and rolled, the other side of the canvas being attached to the rear of the cutter-bar. The ends or journals of the roller H have their bearings in arms or boxes 0, fastened to the under side of the platform. At one end of the roller is formed a pulley, e, to which a cord or rope, e, is attached, that extends over the pulley down underneath the platform, as seen in Fig. 2, passes around a pulley, J, and is attached to a lever, J, in which there is a series of holes for this purpose. To this lever, in the same hole, is hooked the end of a link, I, to the other end of which are attached cords I, that extend round a pulley, L, arranged vertically in the lower corner of the platform, being supported by means of a bracket, a, attached to the platform. The ropes extend up and are attached to the end of a curved arm, P, secured to one side of the swath-board D, as represented in Fig. 3.

To the rear end of the lever J is pivoted an arm, f, the other end of which is pivoted at a to a slide, K, on the shaft 0. S is a brace secured to the platform that the lever slides upon in its movements. From the middle of the slide K extends up a piece made in one with the slide, and forms a journal-box, through which one end of the head of the rake R passes and has its bearing, and to this end of the rake, outside of the box, is secured a curved pin, 1', (seen in Fig. 5,) that rests and moves on a slide, 19, secured to the rear and under side of the platform. In this slide are notches or spaces cut out on one side, near each end of the platform, as shown at a u in Figs. 2 and 5, that allow the pin 7* to turn down, elevating or lowering the rake by means of a weight, t i connected to the end of the rake, as represented.

The rake is constructed in the ordinary way, and from one side project pins i, that fit into and slide in grooves t in the platform. (Seen in Fig. 1.) This is to prevent any grain from rolling under the rake-head in gathering up the gavel.

O is a guide secured at one end of the platform that the end of the rake moves under, above theslide p. There are slats j placed inclined across the corner of one end of the platform to guide the grain down onto the rake.

N is a guard on the upper side of the cutterbar, to prevent any wear or 'tear of the canvas.

R is a shield (seen in Figs. 2 and 4) attached to the under side of the cutter-bar, that curves down round the roller when the platform is lowered to protect it. The roller H, in place of being arranged in front of the platform, can be connected to the rear of the cutter-bar and inner and outer shoes, when the other side of the apron H would be attached to the edge of the platform.

Now, the manner of receiving and dischargin g grain by this raking apparatus, constructed as described, is as follows: The end 0 of the shaft 0 is connected to the harvester by suit able devices for operating it, so that it can be worked either by the driver or by the movements of the machine. When the end 0 of the shaft 0 is turned down toward the rear side of the platform the platform is tipped up into the position shown in Fig. 4, the shaft having its bearings in the arms E and F, and the apron H turning 05 the roller. This movement of the platform, that unwinds the canvas or apron from the roller, winds the cord 6 onto the roller 0. From the connection of this cord with the arm P, at the other end of the platform, by

. the link I and cords l, the lever J is drawn on the upper side of the platform, from the position shown in Fig. l to that indicated by the dotted lines. It is moved along in this direction in an upright position--that is, the fingers project upward at right angles to the platform until it comes to the opening a, when the finger r, passing off the slide, the weight t, being rigidly connected to the head of the rake, will turn the rake down flat on the platform, as indicated, in which position it is carried back to the other end of the platform by the reverse movement of the lever, and which lowers the platform till the rake comes to the space u, when the finger r, passing off the slide into the notch, the weight is so arranged that it will turn the rake up, so that the grain let down upon the platform as it is lowered will be raked up as the rake moves to the other end, or the end A, which extends beyond the shoe or end of the cutter-bar, where it will be discharged in a gavel on the ground.

The apron H receives all the grain that falls from the cutters, and prevents any of it from passing between the platform and cutter-bar when discharging grain, and also prevents the falling grain from mingling with the grain that has already fallen on the platform and is being raked up into a gavel as the platform tips up. The apron H winds and unwinds from the roller automatically as the platform is tipped up and down simultaneously with the movement of the rake, which is carried back and forth in such a manner as to gather up the grain that has fallen on the platform when it was lowered, and discharge it at one end in a gavel when the rake turns down fiat, as before stated, so as not to disturb the falling grain in its backward movementthat is, let down on the platform from the apron as it winds up and the platform is lowered.

What we claim as our improvement, and desire to secure by Letters Patent, is

1. The rake R, pin r, weight t, and slide K, in combination with the tipping platform A, guide 0, and notches u 10, arranged as and for the purpose substantially as set forth.

2. The roller H, apron H, and cords e I, or their equivalents, in combination with the pulleys L J and lever J, substantially as and for the purpose described.

3. The shaft 0, arms E F, and slide K, in combination with the arm f, lever J, and platform, arranged and operating substantially as and for the purpose specified.

4. The platform A, roller H, and apron H, in combination with the cords e I, lever J, and arm f, substantially as and for the purpose described. p

5. Hanging or pivoting the platform A to the rear end of the shoes by means of the arms E and F, when said platform is provided with the rake R, grooves i, and slats j, substantially as and for the purpose specified.

6. Attaching the arm P to the swath-board D, in combination with the cords I, or equivalent, lever J, and platform, as and for the purpose set forth.
