HARVESTER-REEL.

SPECIFICATION forming part of Letters Patent No. 678,432, dated July 16, 1901.

I Application filed August 13,1900. Serial No. 26,718. (No model.)

To aZZ whom it natty concern:

Be it known that I, EDWARD O. BECKMAN, residing at Piper City, in the county of Ford and State of Illinois, have made certain new and useful Improvements in Harvester-Reels, of which the following is a specification.

This invention is an improvement in harvester-reels, having for an object to provide a novel construction of reel which can be opened for use and folded for transportation or storage, can be conveniently applied to and removed from the harvester, and in which the fans or blades can be conveniently centered between the divider boards or shields of the harvester.

The invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a sectional side elevation of the reel, and Fig. 2 is an end View thereof.

The reel, as shown, is provided with a hollow shaft A, which is fitted at one end on the bar or shaft B, which is a part of the harvester and may be suitably revolved in operation by means of gearing with the sprocket-wheel B on the end of said shaft B, asshown. The hollow shaft A is secured on the shaft B by a set-screw C, so it can be conveniently fixed to and released from the shaft B and will partake of the rotary motion of the shaft B when held thereto, as will be readily understood from the drawings.

The fans or blades D may in general respects be of the ordinary construction and are supported and operated by the connecting-bars E and the adjusting-bars F and of which I use two connecting-bars and one adjusting-bar for each of the blades. The conmeeting-bars are pivoted at their outer ends to the blades, extend thence inwardly on parallel lines, and are pivoted at their inner ends to the tubular bracket G, which is fitted on the inner end of the hollow shaft A and secured thereon in operation by the set-screws C and O, the former operating, as before described, to secure the shaft A to the shaft B.

' It will be noticed that the connecting-bars E bars and the bracket, as desired.

The adj usting-bars F are pivoted at their outer ends to the blades and extend thence inwardly in a direction inclined oppositely to that of the connecting-bars and are pivoted at their inner ends to the adjusting-slide, which fits and slides on the shaft A toward and from the adjustable stop I, which is arranged at a point midway between the ends of the shaft A, as shown. This stop I is shown as a pin extending transversely through one of a series of holes 1, formed through the shaftA, so the position of the stop can be adjusted as may be desired. When adjusted to any desired position to fold the reel or to expand the same to any desired extent, the adjusting-slide H may be secured to the shaft A by the set-screw H, which will hold it firmly in place. By means of the adjustable stop and the slide H, moving to and from the same, the operator can center the fans or blades between the divider boards or shields of the harvester, thus avoiding the necessity of adjusting the fans or blades in any way upon their supporting or connecting bars.

It is manifest from the foregoing that the reel can be folded instantly by loosening the set-screw, which secures the slide H upon the shaft A, so the blades will be out of the way of the drivers lines and whip when on the road. It will also be seen that the reel is complete in itself and can be removed intact from the harvester and applied thereto and secured in place in a moments time, this operation simply requiring the operation of the set-screw O to clamp the shaft A upon or release it from the shaft B. By thus conveniently folding and removing and applying the reel it can be removed from the harvester in storing the latter for the winter, thus economizing shed space. It will also be noticed that my reel is only supported at one end, thus facilitating its application to and removal from the harvester.

It will be noticed that the lugs of the tubular bracket G are out of line, so that the reel fans and slats may be folded closely against the shaft.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A harvester-reel comprising the shaft, the fans or blades, the parallel connectingbars between the shaft and blades and forming therewith a parallel-ruler-like construction, the adjusting'bars pivoted at their outer ends to the blades and extending thence toward the shaft in a direction inclined oppositely to that of the connecting-bars, and a slide on the shaft to which the inner ends of the adjusting-bars are pivoted, substantially as set forth.

2. In a harvester-reel, the combination of a shaft, the fans or blades, the connectingbars pivoted to said blades and extending be- 1 .the blades, the connectingbars between the tween the same and the shaft, the adjustingbars pivoted at their outer ends to the blades, a slide on the shaft to which the inner ends of said adjusting-bars are pivoted, and a gage-stop for engagement by said slide, the said stop being arranged on the shaft between the slide and the connecting-bars in position to stop the slide when the latter is set to expand the reel, substantially as set forth.

3. In a harvester-reel, the combination of a shaft provided at a point between its ends with a series of transverse perforations and with a stop-pin fitted thereto, the tubular bracket fitted on one end of the shaft, pairs of parallel connecting-bars pivoted at their inner ends to such bracket, the fans or blades to which the outer ends of the connectingbars are pivoted, the adj usting-bars pivoted at their outer ends to the fans or blades, and the slides on the shaft to which the inner ends of the adjusting-bars are pivoted, the said slides being movable toward and from the stop-pin on the shaft, substantially as set forth.

4. In a harvester-reel, the combination of the tubular shaft fitted at one end for application to a revolving shaft of a harvester, the tubular bracket on said end of the shaft, a set-screw for securing such tubular bracket to the hollow shaft and the latter to the shaft of the harvester, the connecting-bars parallel with each other and pivoted at their inner ends to the tubular bracket, the fans or blades to which the outer ends of the connecting-bars are pivoted, the adjusting-bars pivoted at their outer ends to the fans or blades, and the slide to which the inner ends of the adjusting-bars are pivoted, substantially as set forth.

5. A harvester-reel comprising the shaft, the fans or blades, the parallel connecting bars pivoted at their outer ends to the blades, the tubular bracket to which the inner ends of the connecting-bars are pivoted, the adjusting-bars pivoted at their outer ends to the blades, a slide on the shaft to which the inner ends of the adjusting-bars are pivoted, and set-screws by which said slide and the tubular bracket may be secured to the shaft, substantially as set forth.

- G. A harvester-reel comprising the shaft,

shaft and blades and pivotally connected at their opposite ends to such parts and the adjusting-bars pivoted at their outer ends to the blades and extending thence toward the shaft in a direction inclined oppositely to that of the connecting-bars, the adjustingbars and connecting-bars being pivoted to the blades relatively near together, and the bars and shaft forming an outwardly-converging triangle in the expanded adjustment of the reel substantially as shown and described.

7. A harvester-reel comprising the shaft, the blades, and the parallel connecting-bars between the shaft and blades and forming therewith a parallel-ruler-like construction, the slide and the adj usting-bars extending between the blades and slide, substantially as set forth.

8. A harvester-reel comprising the shaft, the blades, the parallel connecting-bars between the shaft and blades and forming therewith a parallel-ruler-like construction, and adjusting mechanism operating directly upon the blades and adapted to expand and contract the blades uniformly substantially as set forth.
