SUPPORT MEANS FOR IDLER ROLLERS:

Filed Dec. 7, 1945 Patented Nov. 30, 1948 UNETED S TAT ES PATENT G F F ICE SUPPORT MEANS FOR IDLE-R ROLLERS Franklin N. Smith, Cedar Rapids-Iowa Application December 7, 1945, .Serial No. 633,318

7 Glaims. 1

My invention relates to improvements in support means for idler-rollers. and more particularly to novel means for clamping troughing roller fixtures to their supports, the primary object of the invention being to provide means of this character which enable more efli-c-iently, quickly, and securely clamping such fixtures on their supports and removing-the same therefrom.

Another important object of the invention is to provide clamping means of the character indicated which act laterally upon the supports, whether of channel or of angle iron or other type, in either outward or inward directions, and at the same time substantially eliminate overstressing or distorting the supports.

Qther import-ant objects and advantages of my invention will appear in the following description and appended drawing, wherein illustrative embodiments of the invention are set forth only as examples.

In-the drawing:

Figure 1 is a fragmentary side elevation of an arrangement according to the invention utilizing a channel type support frame with an angulated troughing roller, with the clamps acting laterally outwardly.

Figure 2 is a fragmentary left-hand end elevation of Figure 1.

Figure 3 is an enlarged vertical transverse sec tion taken on the line 33 of Figure l.

Figure 4 is a fragmentary side elevation of another arrangement according to the invention, with the clamps acting laterally inwardly Referring in detail to the drawing, the numeral 5 generally designates a type of conveyor belt troughing roller such as disclosed in my co-pending application, filed December 7, 1945, Ser. No. 633,317, (Patent No. 2,e i48,6l6), for Bearing structure for conveyor rollers and the like, involving a hexagonal nut 6 which is removably in serted in a conformingl shaped slot 1 in the upper end of the angulated portion 8 of the T-section stand 9 for quick removal and installation. The fiat base H) of the stand 9 is designed to rest upon the horizontal support member 1 I, with bolts l2 traversing the base iii and the web or flange l3 of the support member at opposite sides of the stand 9. The opposite end of the roller 5 may have any suitable means of removable support (notshown) capable of taking the thrust of the angulated roller.

'In the embodiment shown in Figures 1 and 2 of the drawings, the horizontal support member H is an inverted channelwhich rests at its ends upon the laterally inturned flanges l4 and i5, respec tively, of the corresponding upright l 5 and I l, the said flanges having slanting lower surfaces, to cooperate with the related clamps l8 and i9, respectively.

The stationary hook-shaped clamp l9 has its shank 2i! welded or otherwise suitably secured to a spacer 2i secured to and between the sides of the channel support H near its lower edges, as indicated in the right hand portion of Figure 1 of the drawings, the crook 22 of the clamp reaching downwardly below the channel and around the flange l5.

At the left hand end of the channel H, the spread L-shaped clamp 18 has a vertically arranged shank 23 terminating in the angul-ated foot 24 which extends below the channel and engages under the slanting surface of the flange i l of the upright 1 8. The shank 23 is traversed by a bolt 25 whose head abuts the inner side of the shank and whose body rests upon a spacer 26 secured to and between the sides of the channel ll near their lower edges. The bolt '25 traverses also a plate 2?! abutting the end of the channel and against which the nut 28 is turned in tightening the bolt. When the nut 28 is tightened the channel I l is forced in a right hand direction so that the right hand clamp l9 wedges on the flange #5, while at the same time the left hand clamp H3 wedges on the flange l4, thereby rigidly securing the channel I I to the conveyor frame uprights l6 and ii. It is obvious that simply loosening the nut 28 permits easy and quick removal of the channel H from these uprights. As indicated in Figural of the drawing the upright it may have another lateral- 1y inwardly directed slant face flange 2 9 on which may be mounted-by means of the bolt fill, the upper and lower elements 3! and 32 of a bracket 33, whose vertical part 3 3 maybe slotted at 35 to removably accommodate the hexagonal nut 5-G of a horizontal roller Ere-a, having suitable sup-port means (not shown) for its opposite end.

Referring now to the embodiment of my invention shown in Figure 4 of the drawings, the frame uprights Iowa and lla having laterally outturned flanges id -a and id-a, respectively, instead of the inturned flanges of the above described cmbodi-ment, and the under surfaces of these flanges are not angulated, but the outer edges of the flanges are slotted with angulated edges to cooperate with the clamps, as indicated at 3'5 and .31, respectively.

The stationary clamp l9.-.-a is hook-shaped with its shank eo-a horizontal and secured upon the spacer ri l-11a securcdto the sides .of the channel, the spacer having on its inward end ;a depending extension 40 in the form of a brace, to engage and support the inner side of the upright I'l--a to prevent distortion when the clamping pressure is exerted.

The adjustable clamp l8-a at the left hand end of the channel ll-a has its vertical shank 23-a, on the bolt 25--a between the nut 2&c and the end of the channel from which it is outwardly spaced. The body of the bolt traverses a block 28 fixed in the channel, with the head of the bolt engaging the inner side of said block. An angle brace 39 in support relation to the channel ll-a, and the inner side of the upright l6-a is provided to prevent :distortion thereof when the clamping pressure is applied. It is obvious that tightening the nut 28-a will force the channel H-a in a left hand direction, thereby forcibly engaging the right hand clamp IQ-a with the flange I a, while at the same time the clamp I8a forcibly engages the related flange i l-11, thereby securely clamping the horizontal channel lil-a on the uprights. As in the case of the first described embodiment, the stands for the rollers are to be bolted to the channel I Ia; and the channel may be quickly removed from the uprights by loosening the nut 28-a sufficiently to permit disengagement of the clamps from the flanges of the uprights with which they are engaged.
