This invention relates to conveyers, of that type to be used in construction work on roads, in building tunnels and like uses, and has for its object to provide, in a manner as hereinafter set forth, a conveyer of the class referred to with means, positioned at the lower or material receiving end of the belt or elevator, to prevent mud and dirt from 1 getting on the inside thereof and adherlng to the roller for thebeltand further for cleaning any; adhering dirt from the roller duringthe revolving thereof, whereby the conveyer will not become'clogged and its operation retarded.

Further 0b ects of the invention are to provide, in a manner as hereinafter set forth, a shielding and scraping meansfor use 1n connection with a conveyer of the class referred to and for the purpose aforesaid and which is comparatively simple in its construction and arrangement, strong, durable, compact, thoroughly eflicient in 1ts use, readily installed with respect to the lower or material receiving end of the conveyer, and comparatively inexpensive to set up.

. With the foregoingand other objects in view the invention consists of thenovel construction, combination and. arran ement of parts as hereinafter more speci cally described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but itis to beunderstood that changes, variations aridmodifications can be resorted to which fall within. the scope of the claims hereuntoappended. V In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure 1 is a fragmentary view, in side elevation, of a conveyer, showing the adaptation therewith of a shielding. and a scraping means in a'ccordancewith this invention. Figure -2 :is' a-fragmentary view, 1n top . blocks 1 and 2, see'Figure 3, and the said plan of a conveyer, showingthe adaptation therewithof a shielding and'scraping means in accordance with, this invention.

Figure 3 is a cross sectional-view of the conveyer, at the lower' or material receiving end thereof, and further illustrating therewith the 'shielding and'scraping means in accordance with this invention.- Figure 4 is a fragmentary view in longitudinal section of the lower or receiving. end of a conveyer showing the adaptation therewith of a shielding and scraping means in accordance with this. invention, i

Figure 5 is a fragmentary view -in top plan illustrating the scraper and its support. Figure 6 is a side elevationof one-of the shields or dirt guards. 1 7 Referring to the drawings in detail 1 and 2 indicate the foot blocks which are placed at -the lower or material receiving endofthe conveyer. The blocks 1 and 2 are arranged in spaced relation and are formed with lat erally extending apertured lugs -3, through. which extend holdfast devices 4101' securing the shoe 5, against the upwardly inclined part 6 of the bottom of the said blocks. The

shoe 5 projects laterally from each of the blocks. The side bars of. the "conveyer body are indicatedat 7, 8 and the foot blocks 1 and 2 are connected in any suitable manner to the lower ends of the side bars 7 and 8. Each of the foot blocks'includes an upstanding lug 9 carrying an adjusting screw 10, see Figure 1. Mounted upon each of the foot blocks is an adjustablesupporting plate 11, provided at its rear end with an upstanding apertured lug 12, and with the wall 9f the aperturethreaded to receive the 'adposting screw .10. Plate 11,is furthermore provided atlits outer v side with an apertured lug 13 extending upwardly fromv the upper face ofthe plate. The plate furthermore is formed with, spaced slots. 14 arranged in a row extending longitudinally of the plate, and, between a pair of the slots 14 a bearing 15, is arranged. Holdfast devices extend through the slots 14 and also through the footblocks for connecting the plate '11 to saidblocks. The holdfast devices are indicatedat16 and in connection with the slots 11, provide for the lengthwiseadjusting' of the plates 11 with respect to the foot blocks 1 and 2. Mounted in the bearingv 15, is the lower roller 17, for the belt orelevator. 18.

Each plate 11 is provided with depending spaced. flanges 19 which overlap the foot which provides a reinforcement for the rod 20 and also assists in maintaining the lugs 13 in spaced relation. Each of the plates 11' has its upper portion or inner portion, indicated at 2,3, of greater width than its lower or outerportion 24:. The side platesof the conveyer body are indicated at 26' and.

which are-arranged inwardly with respect to the side bars 7 and& A dumping or drop pan 27 'is positioned against the lower edge.

of the side bars 7 .and 8, at the lower ends thereof, and also positioned against the bot-v toms of the foot blocks at the upper portion operative' relation with the lower or material receiving end of the conveyer. j

Connected with each plate 11 and with a side plate is a dirt guard, referred to generally by the reference 31. The dirt guards are oppositely disposed with respect to each other and are attached to the outersides-of theplates 11 and side- plates 25, 26. The

- dirt guards are bodily shifted with the plates 11 and the plates 11 are shifted for the purpose of taking up; the slackjin the belt or ielGVfttOl 18. The belt or elevator 18 is of the "endless type. The dirt guardsal'e of the same construction, but one will be described, as the description of one'wil'l apply to theother." The dirt guards act as shields for the 'loweror receiving end of the conveyer and prevent mud and dirt from .gettin bnthe -insideof the. belt and adhering :or stic ing to the roller 17. v

wEachydirt guard comprises a-vertically disposed upperportion 32, a vertically disposed-*lowerportion 33-and an inwardly extending and upwardly inclined intermediateportion 34'. The'upper portion 32 ata point between its vertical center andrear end is formed with a lengthwise extending slot 35. The lower end portion 33 at a point between its vertical eenter and its rear or -l5'ower end is formed'with an opening "36.

The guard 31 at apoint between its vertical center and its upper or forward end is ,formed with an invertedU-ishaped cut-out part3? which extends from the lower edge of the guard and. partly through the intermediate portion 34 and said cut-out part-forms a clearance fora'bearing 1 5. The upper end portion 32 of the guard is secured to a side plate by the holdfast device 38 and which extends through the slot 35. The hold'fast device 38 and slot 35 provides means where by the guard can be adjusted lengthwise of that'side plate towhich the guard is "connected. The opening 36'is provided for the passage of. the tie rod 20, and a clamping nut on an end of thetie'rod 20, clamps the lower end portion'33 against the lug the dirt 13, see Figure 3;; The guard 31 "is of approi priate length and provides a shield which is interposed between the lower end of the side plate-andalplate 11. The side plate projects beyond the' lower end of a side bar-rand the guard is positioned at the lower end of the side bar, see Figure 4E.

The means for scraping or cleaning the roller .17 is supported from the pair of plates 11 and is positioned forwardly with respect to the roller 17.

The said means consists of a carrier 39 formed at each end with 'a transverse slot 40. Extending "through the sllots' lO and the openings 30 are holdfast devices 41 which secure the carrier '39 t'o the' plates 11. The-slots 40, in connection with'the 'holdfastdevices 41,pro-

vide means whereby the carrier can be ad justcd towards and from the roller 17, for

the purpose of arranging "the scraper or blades 42 in 'the'desired' position with respect to'the roller 17, to remove the adhering dirt or foreign substances therefrom.
