Saskatchewan; Ganada-l ApplicationFebr-uary 10, 1547; Seri'alNo; 7273474 Iii-Canada Marcli tit 1 944 My invention relates to. an improved. pick-up assembly-for attachment both-e2 cutter-bar guards associated with harvesting implements; such as combines;v binders: andithe like; anzobject; or the invention being to provide a. device whichwill ,1

piclc up allloose -grain without" the end thereof r-unningintothe ground.v

A. further object of my inventicrr is to. pro. vide a device of the character herewithin described which is of eminentl simple construction, economical to manufacture and which will give long service for the-treason- .that. breakages will be most infrequent since the device does not tend to run into the ground as does the conventional pick up'assembly;

With the above more important objects in view andlsuchlother minor objects as: may appear as the specification proceeds, my inventionrconsists essentially in th arrangementand construction of: par-ts all as hereinafter more: particularly: described; reference being harltmthe accompanying drawings in which- Figure 1 is a side elevation of a pick-up assembly embodying my novel; modificationsthere tin Figure 2 is an exploded perspective View of the parts 5 and 8 intended to illustrate the interior structure thereof.

My pick-up assembl comprises the conventional forwardly projecting bracket l which is bolted or strapped to the underside of the usual cutter-bar guards 2 at the points 3 and 4.

The forward end of the bracket I terminates in the stationary part 5 of the conventional two-part hub 6.

My pick-up element 7 comprises collectively the rotatable portion 6 of the hub S which is bolted to the portion 5 at the centre thereof by means of a conventional square headed bolt 9; the forwardly and downwardly curving runner l0 which projects forwardly from the rotatable portion 8; the upwardl and rearwardly diverging carrying arm i i which joins the runner at the forward end I2 thereof; and the carrying arm itself.

The portions 5 and 8 of the hub 63 are hollow on the inside thereby providing a semi-circular housing portion 43 for a cushioning spring M. This cushioning spring is positioned between the abutments i5 and 26, the former of which is integral with the stationary part 5 of the hub while the latter is integral with the rotating part 8. From the foregoing it will clearly be recognized that upon rotation of the pick-up element in a counterclockwise direction, as for in- 5,5

stance when: a, rocle or; hiilockt, encountered, thezupner end of; thee-spring will ultimately: come into contact: withxthe abutment i5 to pltovid'eza cushioning: efi'eota. In; this; contextiit; is however ta-banoted: that. the spring.- i-ihis not. intended tot-extend fOIr the; fulltlengthi or the. scrub-circular housing portion 1| 3; but hunctiona. as: already stated -only as a-..cnshionror:buffer: From this it will be understood that the,element1-is-;free to pick-up, .freely-toriaroertaini extent without the, intervention of; anyyresistance by; the spring;

Upon. the. left. hand side of the; hub-portion 8rwith respecttoali iguneallis a semi-circularrslot I;L. through which asnutl-and stop.-bolt-. assembly LBf-PltOjdGliSi ,itr being: understood: that the: nut of thesassembly 18; may bezboltedi at. arm-point. upon tha-lengtmof: the slot-I51, being intended-to come uplagainstl the, abutment id-and. which: projects from. and is integral. with. the. hubrportion; 5.

In this way, the position of theepickl-upelement 1 may be adjusted although. his; topbe understood .thatl in the; adaptation. of. the. foregoing structure; to, purpose. I do i not make use of such. ad-iustmenh. and furthermore, make use. of, a. shortenanch weaker spring than. is, commonly used in association with pick-up attachments. As has been clearl indicated in the accompanying Figure 1, I permit the runner and carrying arm l0 and H to drop clockwise so that the forward end l2 thereof is as low as possible. Thus it will occupy a position in a plane which is wholly below the lowermost peripheral limit of the hub, or in other words, as low as is permitted by the stop 20 which projects inwardly from the rotating part 8 and moves in the recess 2| in the stationary part 5 until it comes up against either of the shoulders 22 at the ends thereof.

All the foregoing represents conventional structure in relation to pick-up assemblies for attachment to cutter-bar guards with the exception of the fact that my spring I4 is shorter than those commonly used, which latter occupy, while in varying degrees of tension, the full length of the housing portion i3. In conventional practice however it is to be understood that it is only very rarely that it is at all practicable to permit such an adjustment of the hub 6 that the forward end l2 may drop down as far as is permitted, because under such circumstances the point or end l2 repeatedly digs into the ground causing frequent stoppage, breakages and sometimes serious damage.

It is however desirable for maximum downgrain recovery that the pick-up element 1 be vesting conditions to slacken the nut and bolt' assembly l8 such that the pick-up element as-awhole may drop to its limit as illustrated.

Only when the forward end of the pick-up element is in its lowermost position is it possible to pick-up the maximum amount of loosev grain,

but without the extension finger 23, this is not practicable for which reason the forward end 12 must be raised by adjustment of the nut and bolt assembly I8 in the slot l1. But obviously this permits the escape from underneath the pick-up element of a considerable quantity of loose grain. However, by the use of the extension finger 23 which I have now described, the maximum amount of loose grain is collected while avoiding the tendency of the element to dig into the ground.

Since various modifications can be made in I my invention as hereinabove described and many apparently widely diiferent embodiments of same made within the scope of the claims without departing from-such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense and I desire only such limitations placed thereon as are specifically expressed in the accompanying claim.

What I claim as my invention is:

A pick-up assembly for attachment to cuttingbar guards, comprising in combination a forwardly projecting bracket secured to said guard, a circular two-part hub, one part of which is 4 stationary and integral with one end of said bracket, a pick-up element, the other end of said hub being rotatable and integral with said pick-up element, means for holding said twopart hub rotatably together, a runner curving forwardly and downwardly from said hub, said runner constituting part of said pick-up element and being integral with and projecting forwardly from the rotatable part of said hub, a carrying arm diverging rearwardly and upwardly from the forward end of said runner, an upwardly curved deformable extension finger projecting forward from the junction of said runner and said carrying arm, a semicircular housing portion between the two parts of said hub, opposing abutments terminating said housing, one of said abutments being integral with the stationary part of said hub and the other integral with the rotatable part, a cushioning spring within said housing of a length less than that of said housing, the rotatable part of said hub being freely movable without resistance thereagainst by said spring when said runner attached thereto is in ground contacting position, the junction of said runner and said carrying arm lying in a plane below the lowermost peripheral limit of said hub when in situ and when the associated cutter-bar is lying in or below a horizontal plane.
