HARVESTER-IELEVATORi SPEGIFICATION'forming part of Letters Patent No. 513,397, dated January 23, 1 894.

T0 at whom it may concern:

Be it known that I, FRANCIS A. JUDIE, a citizen of the United States, residing at V0- linia, in the county of Cass and State of Michigan, have invented a new and useful Harvester-Elevator, of which the following is a specification. I

This invention relates to harvester elevators; and it has for its object to provide certain improvements in elevators of that character usually employed in elevating the grain from one end of the platform apron directly in rear of the cutting apparatus.

To this end the main and primary object of the present invention is to providecertain simple and efficient improvements in the inclined elevators for harvesters, headers and the like machines, by means of which such elevators are well adapted for elevating all kinds of grain irrespective of its condition, and is especially useful in preventing the bunching of the grain on the platform apron at the mouth of the elevator aprons, and therefore the clogging of the elevator, while at the same time providing means for positively elevating the grain without the slipping thereof during elevation With these and other objects in view which, will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts, hereinafter more fully described, illustrated and claimed,

In the accompanying draWings:-Figure l is a perspective view of a portion of the platform of a harvesting machine, showing my improved elevator attached thereto. Fig. 2 is a central vertical longitudinal sectional view of the construction disclosed in Fig. 1. Fig; 3 is an enlarged detail in perspective of one of the upper apron slats having the improvement claimed attached thereto. Fig. 4 is a similar view of a simpler form of the attachment.

Referring to the accompanying drawings, A represents the platform frame of an ordi-. nary construction of harvester machine, over which travels the endless platform apron B, arranged in rear of the cutting apparatus in the ordinary manner and adapted to carry the cut grain up to the elevating devices which I shall now proceed to describe.

Securely attached to the platform frame A, and arising therefrom at one end of the platform apron B, is the inclined elevator frame 0. The inclined elevator frame 0, accommodates near the opposite ends thereof the upper and lower sets of apron rollers D and D, over which rollers are mounted the parallel upper and lower elevator aprons E, and E, respectively. The upper and lower elevator aprons E and E, are also arranged at an incline within the inclined frame 0, and travel in close proximity to each other in the ordinary manner, so that the grain will be drawn into the month between the lower ends of said aprons, from the platform apron, and elevated between such elevator aprons up to thebinder deck or table or other point of discharge. This construction is well known to those skilled in the art, and in the present invention each of the endless aprons E and E, which are operated by suitable gearing from the platform apron, are provided with the transverse apron slats F, extending transversely across their entire width, and the slats attached to the upper elevator apron each carry a transverse series of carrier straps or fingers G. The carrier straps or fingers G, are arranged in any suitable number on each slat, but alternate with the fingers or straps on the adjacent slat in order to provide an economical arrangement of thefingers, and means whereby one finger follows directly in the space left between the two immediately succeeding fingers in order to catch material which may have been passed by such two fingers. Each of the straps or fingers G, is provided with a notched or shouldered end H, adapted to snugly embrace and fit the outer faces and side edges of the apron slats, so that the straps or fingers can be held firmly in position by means of the screw or pin I, passing through such notched or shouldered ends and the apron slats.

The notched 0r shouldered ends of the carrier straps or fingers which embracethe apron slats may be termed their inner extremities,

and their outer unattached extremities are flanged to receive the cross-slats or bars J, which extend transversely across and beyond the apron and parallel with the apron slats, although when necessary the said cross connecting bars J, may be dispensedwith, as

illustrated in detail Fig. 4 of the drawings, and still an efiective operation of the elevator be secured.

Now from the foregoing it is thought that the operation and advantages of the improvements herein-described will be readily apparent to those skilled in the art. When the inclined elevator aprons are in motion, the projecting carrier straps or fingers G, attached to the slats of the upper apron, sweep around the lower end of the upper apron and over the receiving mouth, formed between such aprons, so that such straps or fingers will beat down all the bulk of the grain standing above .the lower ends of the aprons, and will press it onto the lower end of the lower apron, which extends in close proximity to the platform apron as usual, and thereby cause it to be elevated between both aprons without the bunching of the grain and therefore the clogging of the elevator. Furthermore, it will be apparent that the said straps or fingers also serve to hold the grain onto the lower apron so that it will not slip during elevation, which is ulsually the case with short grain having wel filled heads, which always has a tendency to draw the straw lengthwise. The cross connecting bar J, is especially useful in this connection, that is, elevating short grain, and additionally serves to hold the same to its place.

Other advantages will suggest themselves to those skilled in the art, and I would have it understood that changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-

1. In a grain elevator for harvesters, the combination with the inclined frame and the upper and lower inclined elevator aprons arranged within said frame and having transverse slats; of a series of ofi-standing carrier straps or fingers attached fixedly at one end to the slats of the upper apron, substantially as set forth.

2. In a grain elevator for harvesters, the combination with the upper and lower inclined elevatoraprons having transverse slats; of a series of off-standing carrier straps or fingers having notched or shouldered ends adapted to be clamped onto the slats of the upper apron, the straps or fingers on one slat alternating with those on the adjacent slats, substantially as set forth.

3. In a grain elevator for harvesters, the combination with the upper and lower inclined elevatoraprons having transverse slats; of a series of off-standing carrier straps or fingers fixedly attached at one end to the slats of the upper apron and adapted to have their other outer ends work over and onto the lower apron, and a cross-connecting bar attached to the outer extremities of each series of straps or fingers on each slat, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

FRANCIS A. JUDIE.
