Jan. 26, 1960 F. LO PRESTI SUPPORTING STRUCTURE FOR FLEXIBLE STRAND SIDEFRAME CONVEYOR Filed June 23, 1958 Fig. 2
INVENTOR. Roy F LoPresh' ATTORNEY "nited States SUPPORTING STRUCTURE FOR STRAND SIDEFRAME CONVEYOR Application June 23, 1958, Serial No. 743,836
2 Claims. (Cl. 198-192) This invention relates to flexible strand sideframe conveyors and more particularly to an improved supporting structure for supporting and training the flexible strand sideframes of such conveyors along a given course.
In flexible sideframe conveyors having a pair'of spaced flexible strand sideframes supported at longitudinally spaced locations thereon and flexible troughing assemblies which support a conveyor belt and span the space between the strand sideframes at positions thereon which are longitudinally spaced from the support locations, there is a definite tendency for the strand sideframes to longitudinally shift at the support locations relative to the conveyor course in response to varying load conditions on the conveyor belt.
It is an object of this invention to provide an improved supporting structure for supporting the flexible strand sideframes of a flexible sideframe conveyor with the supporting structure being securely attached to the flexible strand sideframes and longitudinally shiftable therewith relative to the conveyor course without the supporting structure materially moving from the original location thereof.
It is a further object of this invention to provide a supporting structure which supports and trains the flexible strand sideframes of a flexible sideframe conveyor along a given course with a pivotal-supporting means which enables the supporting structure to be securely attached to the flexible strand sideframes and longitudinally shiftable therewith relative to the conveyor course.
Other objects and important features of the invention will be apparent from a study of the specification following, taken with the drawing which illustrates and describes a preferred embodiment of the invention and what is now considered to be the best mode of practicing the principles thereof. Other embodiments of the invention may be suggested to those having the benefit of the teachings herein, and such other embodiments are intended to be reserved especially as they fall within the scope of the subjoined claims.
in the drawing:
1 Fig. 1 is a longitudinal side elevational view of a portion of a flexible sideframe conveyor having the improvements according to the present invention embodied therein;
Fig. 2 is a cross-sectional view taken along the line 22 of Fig. 1 looking in the direction of the arrows:
Fig. 3 is an elevational view taken along the line 3-3 of Fig. 2 looking in the direction of the arrows with portions of the structure illustrated therein broken away, and
Fig. 4 is a plan View taken along the line 4-4 of Fig. 2. looking in the direction of the arrows.
Attention is now directed to Fig. 1 wherein there is illustrated a flexible sideframe conveyor having flexible strand sideframes 12-12 which are supported at longitudinally spaced locations therealong by supporting structures 14-14 which train the spaced strand sideframes 12-12 in generally parallel relationship to each other along the conveyor course and maintain such spacing at a predetermined gage at the supported locaatent Patented Jan. 26, 19:60
' reach 20 of the conveyor belt being independent and separately supported by an idler structure 22 which is carried by the flexible strand sideframes 12-12 at portions thereof which are longitudinally spaced from both the supported locations and the positions at which the troughing assemblies are carried thereby.
Each of the supporting structures 14 comprise a pair of generally vertical extending substantially upstanding relatively rigid supports 24-24 which are disposed in generally transversely spaced relationship relative to the conveyor course and are retained in such positions by a generally horizontally disposed elongated relatively rigid spacer means 26 having the end portions thereof secured, as by welding, to each of the supports 24-24 withthef spacer means 26 extending generally transversely to the conveyor course and being effective to restrain movement of the supports 24-24 and strand sideframes 12-12" generally transverse relative to the conveyor course at the supported locations. Each of the supports 24-24 includes an upper section or member 30 and a lowersection or member 32 telescopically received for longitudinal extension and retraction thereof in order to compensate for any irregularity in the underlying surface'over which the conveyor 10 is trained. A releasable locking means 34, in the form of a threaded eye bolt, is providedv for securely retaining the upper and lower members of each support in a'desired adjusted position. A connecting means 36, in the form of a generally U-shaped b ight which opens substantially upwardly, is secured, as.by welding, adjacent the upper end portion of each upper member 30 for receiving the respective strand sideframe 12 therein and a releasable securing means 38, in the form of a threaded eye bolt, is provided for securely clamping the respective strand sideframe 12 within the connecting means 34.
It is to be understood that in response to a varying load condition 40 on the conveying reach 18 that the flexible strand sideframes 12-12 will longitudinally shift relative to the conveyor course, in the direction of the arrows j A in Fig. 1, and that the supporting structure 14 will tilt" back and forth along the conveyor course at the supported location, as illustrated by dotted lines in Fig. 3. a
In order to enable the supporting structure 14 to be securely clamped or connected to the respective strand sideframe 12 through the securing means 38 at the supported locations there is provided a pivotal tilting means 42 which enables each of the supporting structures 14- 14 to tilt, as a unit, along the conveyor course.
The pivotal tilting means 42 includes a plurality of downwardly projecting pointed portions 44 which are substantially transversely aligned and transversely spaced relative to the conveyor course. In the embodiment of the improved supporting structure 14, as illustrated, the pivotal tilting means 42 comprises a plate member 46 in the form of an elongated diamond secured to the lower end portion of each' of the lower members 32 of the supporting structure 14 with the plate members 46 being normally disposed in a substantially horizontal position with the major axes of the diamond extending generally transversely of the conveyor course and the minor axes thereof extending substantially parallel thereto. Each of the plate members 46 are provided with a plurality of downturned pointed portions 44 which are transversely spaced relative to the conveyor course with all of the 3 downturned pointed portions 44 being substantially transversely aligned relative to the conveyor course, as illustrated in Fig. 4.
A ground supported block means 48 is positioned beneath each of the plate members 46 with the respective pointed portions 44 abuttably engaging the top 50 of the respective block means 48 with the remaining part of each plate member 46 being in vertically upwardly spaced relationship, as indicated by 52, to the respective block means 48 to enable the supporting structure 14 to tilt back and forth along the conveyor course in response to the shifting movement of the respective strand sideframe 12. Further, the side portions 54 of each plate member 46 extend generally longitudinally along the conveyor course and define stop means for controlling the tilting of the respective support structure 14 by engaging the respective block means 48.
While the invention has been described in terms of a preferred embodiment thereof its scope is intended to be limited only by the claims here appended.
