To all whom it may concern.-

Be it known that 1, WILLIAM CRossLnY, a citizen of the United States, and a resident of West Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Conveyer-Scoops, of which the following is a full, clear, and exact specification.

My invention relates to, elevator mechanism of the class in which an endless chain or belt of conveyer buckets or scoops is carried by s rocket wheels or drums to raise material om the lower to the higher loop of the belt and deposit it by conveyer-scoops at the upper of their travel.

turning-point The invention has for its obj ect'to provide an improved construction of conveyer bucket or scoop particularly adapted to dredging, excavating, and placer-mining or digging mineral ore, rocky soil, and ore-sand and for being readily transported, set up, and repaired in districts that are remote from machine-shops and skilled labor.

The invention consists in the novel construction of the scoops and their sectional shell and in the arrangement and combination of parts, as hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation of the lower revolving s rocketdrum or carrier-wheel and section 0 a chain of conveyer buckets or scoops. Fig. 2 is a vertical section, lengthwise of the axle, of a part of the sprocket-drum and chain of scoops on the line m as, Fig. .1, enlarged to twice the dimensions of the parts of said figure. Fig. 3 is a cross-section on the line a; no of Fig. 2. Fig. 4 is a plan viewof the end of a scoop viewed radially from the axle toward the scoop. single carrying-tooth and corresponding section of the disk of the sprocket-drum viewed radially from the periphery of the wheel toward the axle. Fig. 6 is an end view of a bucket or scoop. Fig. 7 shows a part of the upper sprocket-drum and section of the chain of scoops.

Referring to the drawings, A designates one of the polygonal-sided or substantially cylindrical disk-heads of the sprocket drum or wheel, of which there are two to each drum, connected by bolts 1) to the cylindrical hub D. Said hub is generally fastened to its shaft when it pertains to the upper drum or i that driven by the inversion of the Fig. 5 is a plan view of a the motive power; but the lower drum, which is that here shown, is preferably mounted and adapted to revolve upon its shaft E, which is rigidly supported in the lower ends of suitable arms or frames F. To the outer face of each disk are bolted or riveted the pointed carrier teeth 9, regularly spaced around the periphery of the disk, with their points projecting therefrom, as shown. On the inside faces of the disks are similarly secured a series of supportingbrackets h. The series of conveyer-scoops 'L are connected in an endless chain by means of links m,

hinged to the scoops, and they are in part supported on the sprocket-drums or carrierwheels by the pointed carrier-teeth g, which enter the spaces between-the links and engage the roundedends thereof. The carrierteeth of the motive drum thus impel the chain of scoops and those of the driven drum are carried by the chain. The chain of scoops is to some extent supported on the up er drum by means of the engagement of the links with the said carrier-teeth; but its weight is principally sustained by the brackets h, which engage suitable flat seats or bearings h, scoop at each end thereof, being in the present instance a part of the castings comprising the heads i of the scoop. The relation and engagement of the brackets h and seats or bearings h, as shown in Fig. 3, are the same in both the upper and lower sprocket-drums; but in the former case, w ch would be that illustrated by the said Fi 3 considered in an inverted position or analogous to Fig. 7, the scoops rest and ride upon the ends of the .brackets instead of simply matching therewith, as they do in the case of the lower operated at a considerable angle from the vertical it will be understood that the weight thereof would be borne largely by the lower drum. This construction, however, forms the subject of a separate application and need not be further described in detail here, as the present invention relates particularly to the construction of the conveyer-scoops.

Each scoop comprises a pair of heads or sides 1'. of flat form, having a pair of curved peripheral flanges "L on its inside face separated by a space 6 ,which forms a groove in which the ends of the body part or shell of the scoop are received and held by suitable pins driven through both the flanges and the shell, as shown in Fig. 2. The outer of the two forming integral parts of the which flanges is the periphery of the head Q1, and both serve to strengthen the head, which requires no other reinforcing ribs or ridges. On the outside of each head are a pair of cylindrical bosses '6 cast or otherwise made integral therewith and adapted to form j ournals for the links m, which have perforations or bearings n, fitting and received upon the journals i The links are held in place on the journals by caps i bolted to the bosses in any suitable manner, as by means of a single bolt 2', secured through the axial center of the boss, as shown. 7

The curved shell of the bucket comprises a series of parallel strips or staves r, of steel or other suitable metal, having their ends received between the two flanges tof the sides t". They are held in place by pins t, passing through the parts and preferably having their ends bent, clenched, or riveted over to hold them in place. The perforations in the flanges and staves for their reception are so laid out that the pins will exert a keying or drawing action on the staves to force them tightly to the bottom of their retaining-grooves e. It will be seen that the said sectional construction of the shell of the bucket provides a cheap and simple method of forming it and permits easy repair, the staves being readily substituted by new ones when worn. This is the case even if the shell when the bucket is first constructed in the shop be made of one entire piece or of two or three pieces only, for when worn out it may be replaced with staves, and these may be made of any required width. As here shown, they are comparatively narrow, and each is secured by one pin only at each end.

In operation it will be readily understood that the chain of conveyer-scoops is moved along by the rotation of one of the carrierdrums, which by the intermeshing of their pointed carrier-teeth 9 between the rounded ends of the links m conveys the chain with it. The motive drum will generally be placed upermost, and the ore or sand excavated will escooped up by the scoops at the lower turning-point of their travel and raised to the higher turning-point, where it will be deposited. The scoops will be sustained in part by the bearing of the links upon the carrier-teeth, but 0 'efly supported upon the flanges h on the inner sides of the disks of the drums.

I claim as my invention and desire to secure by Letters Patent 1. In elevator mechanism a conveyerscoop comprising in combination a air of ends or heads and a body part or she] composed of longitudinal staves connecting and secured to the heads substantially in the manner and for the purpose specified.

2. In a dredging-machine or digger a conveyer-scoop comprising in combination a pair of ends or heads each provided with a pair of flanges around its periphery, forming an intervening groove at right angles .to the plane of the head, and a series of longitudinal staves or sections forming the body part or shell of the scoop having their ends secured in the grooves of the heads and connecting the heads, substantially in the manner and for the purpose specified.

3. n elevator mechanism, the combination of a pair of ends or heads, each provided with pairs of flanges and intervening grooves, and a body part or shell having its ends received in the grooves of the heads and secured thereto by pins driven through the flanges and shell, substantially as and for the purposes specified. 8o

4. In a dredging-machine or elevator mechanism the herein-described conveyorscoop comprising in combination the pair of ends or heads 11 each provided with the pairs of flanges i around its periphery, and the series of staves or longitudinal sections 1' having their ends received in the grooves between the flanges and secured thereto by pins driven through the flanges and the ends of the staves, substantially in the manner and for 0 the purpose specified Signed by me at New Haven, Connecticut, this 3d day of January, 1905.
