JOHN kC. BRATTLY, OF ST. PAUL, MINNESTA.

GUARD FOR GRAIN-BINDER CONVEYERS.

. Application filed. May 1,

To ZZ whom, 'it may conce/m.

Be it known that I, JOHN' C. Bini'r'rnv, a citizen of the United States, residing at St. Paul, inthe county oi Ramsey and State ot Minnesota, have invented certain new and usc'l'ul Improvements in Guards for Grain- Binder Conveyers, oi' which thefollowing is a specification. v Y

My invention relates to attachments for grain binders, and the object is to provide a guard over the front edge of the endless apron or conveyer that conveys the cut grain to the elevator ot a binder. Said guard prevents wear and tear of the front edge of the conveyer and also prevents said edge and the ends of the cleats thereon from catching and tangling` the grain especially when the grain is ifniXed with vines and weeds of various kinds as is often the case, and to save short grain trom escaping from the machine.

In the accompanying drawing:

Fig. 1 is a perspective iront view of the main portion ot a binder with my'attachnient applied to it. f

Fig. 2 is an enlarged section on theI line 2-*2 in Fig. l.

Fig. 3 is a detail front .view of my attachment removed from the binder.

Fig. a is the same as Fig. 3 only that it is designed to go on a binder having a right hand conveyer while that in Fig. 3 is for a binder having a lett hand conveyer that is a conveyer on the left side of the driver.

Referring to the drawing by reference numerals, 5 designates the reel, 6 the elevator, 7--71 the endless apron or conveyor moving the cut grain to the elevator. 8 and 8a are the usual grain dividing or guiding devices at the front end of the machine, while 9 indicates the sickle bar having sickles 10 coacting with guards 11 to cut the grain. All of said parts are mounted in suitable 'framework only partly shownfsupported on the usual ground wheels like l2 and the bull wheel 13, from which latter operative motion is transmitted to all the working` parts ot the machine. The strncture so far described is varied in some maires of binders but so general in all binders that I need not describe the saine any further in detail. y

I may state, however, as to Fig. 2 that the horizontal traine oi the endless conveyeif' is or may be considerably varied incon-l struction; thus its front sill le may'. be

secured to the rear sill or connected with it by any suitable number and shape of cross bars'l, and longitudinal bolt rods (not shown), or in lieu et such rods it is common to use barsl l7 in Figz having flattened angularly bent ends 1S secured to thegsills -i and l5 by bolts i9 and 20 respectively.

Each bolt 20, whether short or long, is

always longenougli outside the frame to receive a washerQl and anut- 21a.

My attachment consists ot an angle bar preferably made ot galvanized sheet iron and formed with ya vertical iange 23 khaving a series of downwardly open notches 2 adapted to be slipped downwardly upon several of the bolts 2O and be held tightly, thouoh removably, on the sill la by the washers 2l and nuts 21a. The angle bar also has a horizontal Llange QL projectingrear* wardly upon the front edge of the conieyer 7 and the front ends of the cleats 7u thereof (see Fig. 2). Said horizontal flange has at one endan extension 25 projecting,` upwardly and horizontally upon the lower portion ot' the lower member 6a of the inclined elevator @-63 so as to prevent grain from dropping downwardly over the adjacent end ot the endless conveyer 7.

In Fig. 3 24a is a slotted hole to indicate that such holes may take the place of the notches 24. In Fig. 2 26 indicates a solid plate or board s tiifening the traine M-fl 16.

lhile I `have shown my invention as an attachment readily securablc upon the asually existing bolts at the `trent ot a binder conveyer, it will be uncerstood that for binders not already having such bolts it is easy to furnish either bolts, lag-screws or cap screws for the purpose, and it' my device is put on the binder at the -factory it may be secured in place by rivets or any other suitable means.

As already stated, the devicefprevents tangling and clogging, and saves the front part of the conveyer from undue wear and it also aids in saving short grain by preventing its escape at the foot ot the elevator.

l/Vliat I claim is: n

l. The combination with a grain binder liavingg, the usual platform traine and an endless conveyer and an inclined elevator arranged to receiveV the cutvgrain'troin the conveyer; said trame having a front sill, guard lingers projecting ironiythe lower edge of thesill, anangle bar lhaving a vertical flange secured by bolts to the 'front side olf the upper portion of the sill and a horizontal flange projecting loosely over the' lront edge ot the conveyor apron.

2. rl"he structure .specified in' claim l, in which the elevator has an upper and alower endless inemher and the horizontal flange or' the angle bar has at one end an extension projecting upon the lower end of the lower ineinlier 0l' the elevator.

The structure specified in claim l, in which the angle bar hee its vertical flange provided with clearances for the nsn'al bolts extendingthrough the front sill 01": the conniark
