ATTACHABLE GRAIN-ELEYTKING GUARD.

Specification of Letters Patent. l

Batented Dec. 18, 191

Application filed December 15, 1913. Serial No. 806,726.

To all whom t may concern:

Be it known that I, WILLIAM M. WAD- LEIGH, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented avnewand useful Improvement in AttachableGrain- Elevating Guards, of which the following is a specification.

This invention relates to improvements in attachable grain elevating guards and more particularly to improvements on the type of the grain elevating guard on which a patent was granted to me No. 733,442 on July 14, 1903.

lObjects of the invention are to provide an adjustable grain elevating guard of the general type shown in my said patent and so constructed that the cost of assembling is materially decreased and which is furthermore provided with means for positively preventing too great a movement vof tlieadjustable arm, said means also serving to prevent loss of the locking bolt and to prevent dust or dirt or other foreign matter collecting in the pivotal connection between the stationary supporting arm and the ade justable arm.

The invention furthermore consists in the improvements in the parts and devices and in the novel combination of the parts and devices herein shown, described or claimed.

In said drawing Figure l is a side elevation of a grain elevating guard embodying my improvements, the same being shown attached to the iinger bar of a harvester or like machine, the finger bar being shown in section. Fig. 2 is a detail part side elevation, part vertical section showing more clearly my improvements. Fig. 3 is a top plan of the structure shown in Fig. 1 and Fig. 4 is a detail, vertical section taken on the line 4-4 of Fig. 2.

In said drawing 10 denotes the finger bar of a harvester or like machine having finger guards 11 secured thereto and provided with a sickle 12 and sickle bar 13, all arranged and operating in any well known manner. The attachable grain elevating guard is designated generally by the reference A and the same comprises a lower stationary supporting arm 14 recessed at its rear end as at 15, thus providing lower and upper fingers 16 and 17 respectively, the upper finger 17 being slightly resilient to adapt the attachment to be secured to different sized nger bars, the lower arm of the attachment being securedin place by' a bolt 18 and nut 19. vThe lower arm 14 extends forwardly and downwardlyv for the greater part of its length and is provided with a short upwardly inclined bottomface 20 at its forwardend and ispointed, as shown at 21.

Thel point 21-is connected to the upper face of the mainv portion of the supporting arm 14 by a narrow web 22 cast integrally therewith. The adjustable arm .23 is-pivoted to the` web 22 by ypivot pin or rivet 24, the lower ,7.

Vfront end'of `the arm A23 being forked as at 25, 25 to straddle the web 22. The pivoted thereby hold the arm 23 inany of its severalpositions. 'Ihe ypointedend V21 of the supporting arm` is provided with a relatively wide, upwardly and rearwardly extending flange or lip 30 which extends .over theupper surface 31 of the adjustable arm 23, as

shown most clearly in Fig. 2. This flange or lip 30 is also extended in width so as to cover the joints 32 formed between the web 22 and the forked ends 25 of the arm 23. The lower ends of the forked arms 25 are rounded and the point 21 is also rounded as at 33 to correspond therewith and permit free movement of the arm 23.

The flange 30 which extends over the upper surface of the 'adjustable arm 23 will positively prevent the latter from being swung up more than the amount .shown in Fig. 2, or in other words the flange 30 serves as a limiting sto'p. By providing this flange, I am enabled t0 assemble the parts much quicker, and without the necessity of any filing or other adjustment, than is possible in the construction shown in my said VPatent No. 733,442. In the patented construction, the adjustable pivoted arm and the supporting arm were pro-vided with small narrow shoulders which necessitated the accurate location of the pivot receiving holes in the two arms and also the ling of the two engaging shoulders. In the present improved construction, the pivot receiving holes of the twomembers do not require such nicety of location as in. the patented structure and iling of the parte to insure the proper adjustment is entirely done away with and I have found that the cost of ase sembling the improved strueturedescribed herein is approximately fifty per cent. less than the oost of assembling the device shown in my said patent. Another advantage secured by the present construction. lies inA vposition with t-heresult that the locking bolt and spring would fall: out. This was due to the fact that the extremely -small and `finely adjusted engaging shoulders fon the pivoted arm v andJ supporting arm soony wore 06?` and permittedthe pivoted `arm to be swung far beyond." its intended uppermost v position.

Another advantage inherent lin my improved construction resides inl the fact that the iange- 30 yis made of such width as to com- Vpletelyzcover thetwo joints 32 between the pivoted parts and thereby prevents the lodginent of any dirt, dust or other foreign Amatter therein which would'linterfere withlthe easy adjustment of the pivoted arm.

Although I have herein shown and de'- scribed what I' now consider the preferred embodiment of my improvement,y yet it will beunderstood that various changes and modifications may bemade without departing from the spirit of the invention, and all such changes .and .modifications are contemplated a's come within the scope of the claim appendedy hereto.

I claim A'. detaehablm grain elevator guard for harvesters and the like, comprising a supporting arm havinga-pointed front end and recessed at eaohside back' of said end to provide a` central web; andan elevating arm bifureated. at its lower-end and thereby embraeingsaid lweb-with its side portions resting in said reeesses and-pivoted to said web, saidv arms having interlocking parts one of which is movable, whereby the elevating arnr is Vheldin adjusted elevatedA position, saidsupporting. arm-havinga rearwardly eX- tending lip engaging over the elevating arm above said pivot Vand 'acting as aV stop to limit :the upward 'movement of the elevating arm and maintain said interlocking parts from passingy beyond." their operative-rela tion.

Signed` 'at Chicago,-Illinois,this 11th day ofjD'eeember, 1913, inthe-presence bf two subscribing witnesses.
