UNITED STATES WILLIAM E. PHILIPS, or CLEVELAND, oHIo.

BELT coNvEYER.

` Application filed April 29, 1922. Serial No. 557,468.

To all 40710411. it may concern:

Be it known that I, WILLIAM E. PHILIPS,

' a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in a Belt Conveyer, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention vrelates to supporting means for belt conveyers ofthe character wherein an endless belt structure supported on rollers is used to convey material from .1'5 f provide a rigid support `for the rollers orv one locality to another.-

The general object of the invention 1s to idlers of a belt conveyer which -can be rapidly made and assembled in position and economically maintained in operatio'n.- A

further object is to so'a'rrange the support that its upper end may lie within the cupshaped end of the roller, thus reducing the necessary space between adjacent rollers.

In its preferred form, the invention is embodied in an L-shaped supporting bracket for belt conveyers comprising a supporting member and an angularly arranged base member, the parts being made in one inte' gral structure, either by castingfor by stampino'.

I)ther objects of the invention will be apparent from the following description, taken in connection with the accompanying drawings, wherein Fig. 1 is an elevation of a belt conveyer support showing the details of my invention; Fig. 2 is an end view of two of' the supporting members arranged-side by side; Fig. l*3"i's a perspective detail showing one of the'supporting brackets; Fig. 4 is a plan showing the development of the bracket shown in Fig. 3; Fig.A 5 is a side view of a modified form of the supporting bracket,

support 15 are indicated as removably se-v cured to the members 12, While the intermediate portion adjacent the angle 18 may beas secured to a membe` 14 which may be a structural shape extending across the base 10.

Each bracket is preferably secured to a straight portion of a support intermediate the angular bend 16, 17, etc. The brackets 2l support idle rollers 22 which are arranged to rotate on axles 23 fitted in slots 24 in th ends of the brackets.

The preferred form of brackety which is shownv in detail in Fig. 3 comprises a strip of sheet metal 30, the development of which is shown in-Fig. 4. The strip 30 comprises pats for forming an upper portion 31 and a pair of lower4 portions 32 having a slit 33 therebetween. n

In bending up the bracket from the blank shown, the portions indicated at 35 in dotted lines, Fig. 4, are turned to stand at rightangles to the main body portion of the bracket to form stiffening ianges, While the lowerv portions 32 are bent on a line 37 to stand at substantially a right angle to the main body portion. The lower portion of the bracketis provided with apertures 38 Awhich are adapted to receive a fastening member, whereby it may be'secured to the support, while the upper end of the bracket is indicated as provided with a notch or recess 39 which is adapted to receive the support for the pulley idler. A reinforcing rib 40 shown as of an inverted Y-shape may be provided to stifi'en the bracket.

The bracket thus described, it will be noted, comprises an upstanding portion 41 and a pair of laterally extending flanges 42. The angle between the flanges 42 is prefer-l ably a right angle so Athat the bracket -may' bracket can be secured to a plane support. In

assembling' the'structure, the bracket 21 may 'be secured to the supporting member 15 by suitable means, such as bolts 43 and the pulley idlers maybe secured to the. bracket or they may be arranged with their axles merely resting in the slots 39, since the weight of the idler together with the weight of the belt thereupon will prevent them from bein'o displaced. l

ach bracket is preferably bent to provide upper and

lower portions

44 and 45 which are preferably substantially parallelwith each other, whlle the intermediate connecting portion 46 is arranged at an angle to the other two portions to thus dispose the portion 44 to one side vof the portionj45'. This arrangevment is such that inthe completed bracket,

thev portion 44 being offset from the portion 45 may stand within the end of the pulleyidler' which is preferably cupped as -at 47. Two pulley idlers may thus have their contiguous edges arranged quite close together and thereby theconveying belt may be supported throughout substantially its entire width.

' Each idler is preferably provided 'with.a'

coupling 50 for connection to a grease gun,

- while the interior ofthe idler is provided -with bearings 51 which are arranged adja- "cent a grease reservoir chamber 52. The

upwardly extending arm 60 having a slot 61 in the upper endv andis provided with a' lower supporting portion 62.3 This supporting portion 62 may comprise'two flanges 'which may be arranged one at right angles to the other to straddle an angle iron, or the anges may be plane to fit a flat member.

In this modification, apertures 63 may be provided for removably securing the bracket in place. Y

The arrangement of the brackets intermediate the bends 18 is such as to'allow the' Qparts to be very readily assembled', while at the same time providing a rigid struc ture without waste of material..

Having thus 'described' my invention, I claim 1. The combinationv of a pulley idler i, having a cupped end and asupport 'for the idler, said support comprising a base member and a pair of independent bracketssecured tliereto,'each bracket having an upwardly extending holding portion ttedto the idler within thecupped end.

2. The combination of a pair of pulley idlers having their axes arrangedat an angle one to the other with the tops of the l pulley idlers arranged contiguous to each other, andthe bottoms spaced apart, two

independent supporting brackets mounted beneath the idler's, said brackets extending between the lower spaced portions of the idlers whereby they maybe supported with .the upper portions contiguous, said pulley'- idlers having cupped ends and the supporting brackets having portions which enter the cupped ends to support the idler.

3. Inga -device of the character described,

the-combination of a' supporting bar, brackets'secured thereto, al roll between the brackets having inside bearings and reentrant ends, a shaft within the bearings extending beyondthe adjacent portions of such ends .and mounted .in the brackets, the brackets being'independent of each other and having their upper portions closer together than the length of thev roller at its periphery.

4. A support for a belt conveyer comprising a'bent'transverse bar, a series 'of independent L-shaped brackets secured thereto,l in pairsback to back, rollers each located between two brackets of adj aoent pairs, each roller having a cup-shaped end, ashaft extending through each roller into such cup shaped end portion, inside bearingsbetween the roller and the shaft, said bracketsv'at their upper portionsfextending within the cup-*shaped cavities of the rollers and there engaging such shaft..

5. In a conveyer support, the combination of a V-shaped transverse bar with its apex upward, brackets secured to said bar and having V-sharped feet, whereby the shape of the bar automatically vpositions the brackets in alignment,and rollersl between thebrackets.

6. In a conveyer support, means for maintaining conveyer supporting rolls -in a position tomaintain the belt in trough shape. said means comprising a V-shaped angle iron, having its apex 'toward the rolls, said angle ironv being bent to conform longitudinally substantially to the`trough shape of the belt'in cross section.v`

7. In `a conveyer support, a series of members arranged at different inclinations to each other, rolls rotatably mounted thereon, whereby a trough support for a belt is provided, standards intermediate of said members for holding them in position,y an angle iron for supporting said standards and shaped longitudinally to conform substantially withthe trough shaped belt, said angle iron being V-shaped in cross section ,hav-

ingl its apex 'toward said rolls whereby the accumulation of dirt thereon is. prevented. 8. In a belt conveyer, the combination xritlx longitudinal supporting members, of standards carried thereby 'having their upper ends inclining downwardly in opposite directions, a `cross beam in the form of an angle bar with its ridge uppermost resting on and secured to the tops of said standards, brackets having their under surface complementary to the upper surface of said angle bar, said brackets resting on the an' gle bar and secured thereto in aligned position, and rollers between the brackets.

In testimony whereof, I hereunto affix my signature.v
