FLOATING GRAIN. LIFTER Filed May 18, 1956 AlQi E/sw keg United States Patent FLOATING GRAIN LIFTER Anton Edward Fisher, Calgary, Alberta, Canada Application May 18, 1956, Serial No. 585,732

1 Claim. (Cl. 56-312) My invention relates to pick-up attachments for grain harvesters, having reference to improvements on a device for which a patent was issued to me in the United States of America on the 14th day of February, 1956, under No. 2,734,332.

The purpose of the present device is to provide certain improvements on the pick-up attachment as disclosed in the above patent, designed to materially lessen the manufacturing and shipping costs and make the device more readily marketable.

To this end I have improved the pivotal mounting for the runner by providing a single casting fixed to the runner and thereby simplifying the manufacturing and assembly of these parts; and there has further been provided an improved runner and tail piece formed of a single piece of tubular material.

Additional to the foregoing I have provided improved means by which the runner may be secured to different makes of harvesters in which the cutting bar bolt spacings vary.

Other features and advantages of the improvements will become apparent by reference to the accompanying description taken with the drawings wherein like characters of reference indicate like parts throughout the different view and wherein:

Fig. 1 is a side view of a grain lifter embodying my improvements, shown as in attachment to a harvester cutting bar and with parts broken away and in section.

Fig. 2 shows a top plan view of the device as illustrated in Figure 1.

Fig. 3 shows an enlarged side view of an eye bolt for attachment of the runner to the cutting bar.

Fig. 4 shows a plan view of a fragment of a runner, partly broken away and sectioned, and illustrating a somewhat different form of attaching bracket for the runner.

Fig. 5 is a side view of the parts shown in Figure 4, but with the rear end of the tail piece broken away and the attaching angle brackets omitted.

Fig. 6 shows an enlarged fragment of a shaft for attachment of the runner bracket shown in Figures 4 and 5, and including an attaching angle bracket and bolt, the latter being shown broken away.

Fig. 7 is a top plan view of the showing in Figure 6, but including a full view of the bolt end together with its attaching nut.

Having reference to the drawings 1 indicates a runner with shoe 2 and finger 3 at the forward end. The runner rearwardly bends to provide an integral tail piece 4 extending rearwardly parallel with the runner, the tail piece including a flat end 5 for bearing fiat against the under side of the harvester table 18. This runner and tail piece are formed of light weight tubular material, steel or an alloy, avoiding the cost of connecting the tail piece and runner together as in the previous patent and materially lowering the weight, which is important 2,8 1 6,412 Patented Dec. 17, 1957 in shipping by express, as is the method largely employed in delivery of articles of this kind.

For attachment of the runner to the harvester I provide a bracket formed of a single iece of material having front end portions 6-6 that are fixed to the sides of the runner and outwardly projecting side members 7 and 8 extending back from the front end portions. These side members are joined at the rear by a cross bar 9 supported by an upright 10 on the tail piece.

The cross bar 9 has inwardly turned cars 11 at the ends and spaced to the inside of these are further cars 12. In the pairs of ears so formed are carried pins or bolts 13 on which the heads 15 of the eye bolts 14 engage to pivotally attach the runner mounting bracket to the cutting bar 17 of the harvester. The heads 15 of the eye bolts 14 are formed offset from the bolt shanks, as is more readily apparent by reference to Figure 3, to facilitate attachment in certain types of harvesters where only a small space is available for the bolt heads. Washers 14' are provided for the bolts.

In Figures 4 and 5 is shown a runner mounting bracket that is formed of a single piece of material that has been moulded to fit on top of the runner and provides lateral wings 21 and 22. The rear end portion of this bracket curves upwardly at 23 and in this a rod or shaft 24 is fixed. This bracket projects rearwardly of the downward bend in the runner, such amount as may be required, and may be supported on the tail piece in the manner shown by the support 10 in Figures 1 and 2.

The shaft 24 carries at the ends angle brackets 25 formed each of two legs right angular the one to the other, the brackets providing openings at 26 to engage the shaft 24 in one leg and further openings 27 in the other leg by which bolts 28 may be used for attachment to the cutting bar 17 in place of the eye bolts 14. Cotter pins 29 are used to retain the angle brackets 25 on the shaft 24.

Such an arrangement provides for considerable variation in the spacing of the bolt holes in the cutting bar of the harvester. These brackets 25 may also be used engaging the bolts 13 of the runner mounting bracket shown in Figures 1 and 2 in place of the eye bolts 14 to accommodate the attachment of the runner bracket in this showing to different makes of harvesters.

In the use of the device the runner pivots in the heads 15 of the eye bolts 14, which bolts 14 replace the bolts already in use in the cutting bar of the harvester. These replaced bolts may be used to provide the bolts 13 of the runner attaching bracket.

Essentially the two forms of bracket function the same, other than that the means for pivotally attaching the brackets varies. In the showing in Figures 4 and 5 a single shaft is employed and in this the angle brackets 24 replace the eye bolts 14 by the use of bolts 28. It is to be understood that such a shaft and angle brackets could be used in the runner attaching bracket shown in Figures 1 and 2, or the angle brackets could engage the bolts 13, these angle brackets being thus adapted for use with either form of runner attaching bracket.

While I have herein disclosed preferred embodiments of my improvements, changes would be readily conceivable, but in so far as such changes come within the spirit and scope of the invention as defined in the appended claims they would be considered a part hereof.

Having thus particularly described and ascertained the nature of my said invention what I claim and wish to secure by Letters Patent is:
