`CONVEYER ROLLER.

Application led September 29, 1924. Serial No. 740,588.

To all whoml it may cio/mem.' A

Be it known that'I, GORDON W. BEULKE, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have vinvented new and usefiil Improvements in Conveyer Rollers, of which the following is a specification.

This invention relates to conveyer rollers and p'artidiilarly to rollers which are revoluble upon rods extending axially therethrough, and ,fixed at their ends in supporting side railsl The object of this invention is to provide inexpensivev and eilicient means for securing the supporting rods forpsuch rollers to the side rails. l,

More particularly, vide lnovel fastening means adapted to transmit en thrust to the rails while permitting quick and easy insertion and removal of the rollers.

Infthe accompanying drawings, which illustrate the best form of my device at present known to me, Fi ure 1`is a side elevation of the invention, s owing the roller partially in central, vertical section; Fig. 2 1s gether with a fragmentary portion of one of, the supit is my vobject to profor the rods porting rails; and Fig. 3 isA an enlargedperspective view of an end of the anual rod.

.Referring to the drawings, I have used the numeral 4 to indicate the` roller body which is provided in each end with a recessv for an anti-friction bearing 5 adapted to transmit end thrust to a sleeve 6 u on an axial rod 7. This rod 7 is supporte at its lends in a pair of., side rails 8 connected by transverse frame members 9..

The rod 7 is circular in cross section throughout its length with exception of a short' flattened ortion 10 near one end. One of the rais 8 has a punched hole formed to fit the flattened end of the rod 7, While the opposite rail has a circular hole throng which the rod 7 may be in= serted. Near its outer extremity,'close tothe face of the rail, the portion l() has a perforation 11 adapted to receive `a 'stout Cotter key 12. This key 12 revents accidental removal'of the rod -7 rom the rails and roller and constitutes an abutment for end thrust in one direction. End thrust in the opposite directionistransmitted to one revent rotation thereof and to lof the rails 8 by a shoulder 13 at the inner end of the portion l() of the rod 7.

As will now be readily understood, the roller 4 may be quickly and easily mounted between the rails 8 (said rails have been previously joined in parallel relation by the member 9) by merely inserting the rod 7, flat and foremost, successively through the rail having a circular perforation, axially through the bearing sleeves 6, and then into the non-circular hole in the rail at the right, as shown in Fig.v 1. lVhen the cotter key 12 4is finally placed'in the perforation 11 and secured therein in the usual manner, the roller is held in spaced relation with the side rails, end thrust being transmitted -to ple of the rails bythe key.12 and shoulder It will be noted that the sleeves 6 maintain the roller 4 in proper spaced relation to the rails 8, but were the key 12 or shoulder 13 omitted, end thrust applied to the roller would cause the rod 7 to work out of its bearings in the rails. In order to insure uniform wear on the sleeves 6, it is necessary to allow said sleeves to rotate slowly or creep upon the rod 7. A rod which is circular in cross section within the sleeves 6. is, therefore, practically essential to eicient working of the bearings. Qbviously, rotation :of the.v rod 7 in the rails is prevented by the flat portion 10 which fits' the punched hole in the rail. tween the rod and 'rails is prevented and unusually free rotation and secure mounti fr of the roller is obtained.

Thus wear beaving described my invention what I claim as new and desire to protect by Letters vPatent is: v

1. The combination` with a roller adapted to be journalled between appair ofside rails, of a circular rod extending. axially through said roller and arrangedto be supported at its ends in said rails, said rod bein adapted to be withdrawn longitudinally 11i-said rails without separationof Said rails, a noncircuiar portion on an end of said rod disposed to project through, and fit within, a

ole in one of said rails whereby said rod is prevented from turning in said rails, and removable fastening means on the projeetin end of said non-circular portion adapte to prevent longitudinal withdrawal of said rod from said rails. 1`

2. The combination with a pair of rails "1n saidrod for engagement rigidly Vconnected one non-circular" portion rod adapted to fit within an opening in one of said railswhereby said rod is prevented 4formed in said rod circular portion, adapted to constitute ay rigidly connected one to the other in parallelrelation, of a roller adapted-to be revolubly mounted between said rails, a rod extending axially through said roller and arranged to be supported vat its ends in said rails, one end of said rod being free for lon 'tudinal movement in one of said rails', a s oulder .formed with lthe inner surface of the other of said rails, said shoulder constituting a stop for end movement of said'rodin'one'direction and removable means engaging said rod adjacent to the outer l adapted to prevent' longitudinal Withdrawal of said rod from said rail in the opposite direction. o

3. The combination lvvith'a pair of rails to the other in parallel relation, of aroller `adapted to be revolubly mounted between Saidrail's, a rod extending axially through said roller and arranged to be supported at its endsl` in said rails, a near an end of said from turning in saidY rails, the other end of said rod being xfree for longitudinal movement in the other of said rails, a shoulder adjacent to said nonstop for longitudinal movement of said rod in one dlrection and removable means en surface' of said lastmentioned rai-l,`

ing a stop for end l gaging said rod adjacent to the outer surface of said last-mentioned rail adapted to prevent longitudinal Withdrawal of said rod in the opposite direction.' g

4. The combination with a roller adapted to be journalled between a pair of Side rails, of a rod extending axially through said roller and arranged to be supported at its ends in said rails, bearing sleeves revoluble on said rod adjacent to the inner surfaces of said rails, and arranged to transmit end thrust to the rails, anti-friction bearings revoluble upon said sleeves and adapted to coact therewith in transmitting end thrust from the roller to said rails, a non-circular portion on one end only of said rod, disposed to project through and tit within a hole in one of said rails, whereby said rod is prevented from turning in said rails, a shoulder formed in said rod-adjacent to Said non-circular portion for engagement with the inner surface of one of said rails, said shoulder constitutmovement of said rod in one direction and removable means engaging said lrod adjacentto the outer surface of said last mentioned rail, adapted to prevent Withdrawal of said rod longitudinally in the other direction. Y.

In testimony whereof, I have hereunto signed my name to this specification.
