Another object is to provifle e device of this diameter, in Wl'aleli the framework will loe 'strong :intl durable and may loe supported upon en iircliue. A l i m 'lig further object is to prof/1de ai device of this olmraeter in which the iiiovalole mehr ber will be oompoeecl of pair of Sprocket skeins connected by cross@ here to which is seourel e flexible endless member composed of canvas or other suitable reattori:ll`

A further oojeot is 'to provide a rlevice ol this charac-ter in which the endless flexible member5 cross bere, amo. endless Sprocket chains may loe securely connected to one mi other, whereby said parte *will be retained in their uroper relative rloeitioiis.

llith t 1e Aaloove and otller objects in View, my invention consists in italo novel ooit structione, combinations, and arrangements offparte to be hereinafter more l'iilly ilescribed, claimed, enel illustrate@ iii the om eom'pzmying clrewlngs in Wliicli Figure Il a, plein View of my Complete device; Fig. t2 is :t eide elevation oil* the clevliee.

Referring more speeieally to the llrewf `liege in which similar reference elmrectere designate corresponding; parte throwglioiit` the several views, l designates the main longltudmal members ol? the traine wliieli :ire connecteol by the transverse frame riiemloere 2 which are sedere-rl against tl'ie 'uixcler :time

The ll-elmoel brace members 5 and; thin longitudinal riietollio stripe Will serre to limit downward njiovoliieiit or slicl ing of the lower or under portions; of the -iiiovnlnle members or the conveyor, will 'be later clearly apparent.

Secured to the upper :Fae/oe ol the trame vi/erse frame members 2 are lille 'thin upper longitudinal metallic Stripe 7 over wliioli' tlie movable Continuous Flexible member ot the. eoiireyer moves, :mill Stripe 7', together "with the transverse frame iriomlyeis Serv iiirg` to 'Clit-fuit clowim'zlrtl movement ol the ui portion of soii'l ile:-; il le member will n Jr provet sagging o the :mme iiurrngopere,- tlori of the device, as will also be later clearly apparent.

When desired, the rearsupportin'g legs 15 may also beemp'loyed, each rear leg being composed cfa pair of members crossed adjacent their 16, said crossed members being adapted to ends of the rod 17 secured transversely through the main longitudinal frame members l adjacent the rear ends of the latter, rit being understood that thecrossed members are connected adjacent their lower ends by the connectingwire 18 or the like to limit outward movement or spreading of` said lower. ends' of the crossed members. A v

The bearing blocks19 are secured to the outer facesof the main longitudinal frame members 1, at the opposite ends thereof andl the shafts 2O are mounted for rotation in said bearing blocks, said shafts-20 having thesprocket wheels 21 mounted thereon between the main longitudinal frame members 1 and one of said shafts being also provided with asprocket wheel 23 outwardly of one of said main longitudinal frame members for engagement by. a chain 23` connected to thesprocket wheel 23 mounted on the drive shaft 24 which has one end squared to receive a suitable crank (not shown), by means of which the drive shaft 24: .may be rotated.

Engaged around the corresponding sprcket wheels 21.- upon the shafts 20, are

the endless Sprocket chains 25 which are connected by the cross bars 2G, the endless Hexible member or apron 27 being secured to the under faces of the cross bars 26 by the securing strips 28 positioned against the under face of the endless flexible member or apron and fastened to the cross bars, with which said securing strips are parallel, thereby securely clamping the endless flexible member or apron 27 between said cross bars 26 and securing strips28. By connecting the movable members of the conveyer in this manner, said movable members. will be at all times retained in proper relation to one another during operation of the device and the cross bars 26 will serve .to retainmaterial in pro'per position' upon the endless flexible member or apr'n 2.7 while said-material isk being elevated to the upper end of the conveyer. AS the material 'reaches the upper tudinal edges secured -`upon the curved 'arms 31 which are hinged to the upper face of the main longitudinal vframe members 1 at spaced distances from the upper ends of the latter, as shown at 32, and having their lower faces cut away, as shown at 33, in order that the greater portions of said arms may rest upon the upper faces of the main longitudinal frame members 1 while the free ends of said curved arms 31 project over the upper ends of said main longitudinal frame members '1.

To guide the material tudinal center of the endless flexible member or apron 27, I. have provided the inclined guide members 34nd: the forward end of the frame and secured upon the main longitu- Ydinal frame members 1, said guide members 34 being inclined downwardly and inwardly toward thelongitudinal center of the endtoward the longirea'dily understood. I have also provided a sto plate 35 at the lower end of the frame, said plate being secured to the lower ends of the inclined guide members 34 to prevent any material from falling off of the lower .end of the conveyer.

From the foregoing, it will be apparent that I have provided 'an endless conveyer or elevator which may be of'extremely simple and cheap construction but which will be strong and durable in use and which will be especially adapted for use in elevating dirt l during operation of digging an underground silo or the like and wlnch is also especially adapted for elevating ensilage and conveying Said ensilage to the desired point.

While I have shown the preferred embodiment of my invention, it 'will be understood that minor changes in the details ofconstruction and arrangement of parts may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing anyof the advantages of the same.

What is claimed isz- 1. A device of the class described com rising a frame including upper longitu inal bars, transverse bars connected to the lower faces of the longitudinal bars, lower longitudinal bars positioned against the lower faces of the transverse bars, transverse brace members secured tothe lower faces of the lower bars and having their ends extending upwardly and secured to the transverse bars,

incense member.

2. A device of the class described compris- "ing e frame including upper longitudinal bers, transverse bars secured against the lower faces of' said upper bars, 'lower longitudinal bers positioned against the lower faces of the transverse members, transversely extending brace members secured against the lower edges of the lower longitudinal freine members, longitudinal brace' strips connected to the upper races of the transverse brace y strips ond to the upper faces of the trans` verse bars, an endless conveyer member mounted in the treme end eztendingeround seid transverse bers, said longitudinal brace `strips being adapted to support the upJerl end lower stretches of ithe conveyorv mem er to prevent the same from sagging, and means for supporting the frame in an eleva-ted postion.

in. testimony whereof I hereunto aix my signature'ln the presence of two Witnesses.
