1933- c. A. M KENNY SELF LOADING AND UNLOADING TROLLEY CONVEYER Filed May 15. 1930 INVENTOR Cbnrlssfi Makfsnny ATTORNEYS Patented Aug. 15, 1933 I PATENT OFFICE SELF-LOADING AND UNLOADING TROLLEY CONVEYER Charles A. ,McKenny,'Detroit, Mich, assignor to The Joseph E. Barrett Company, Detroit, Mich., a Corporation of Michigan Application May 15, 1930. Serial No. 452,756
6 Claims. .(Cl. 214-60) The present invention pertains 'to a novel mechanism for automatically opening and closing suspended bucket type trolley conveyers. 4
The primary object of thepresent invention 5 is to devise a novel conveyer including an opening and closing mechanism for the buckets forrning a partthereof and thus provide a conveyer that is adapted for carrying various kinds of materials or parts from one department to another in industrial plants in order to complete an assembly. In this use the different materials and parts must be unloaded at various points in the assembly line and therefore-the present invention provides a mechanism on the bucket that is engaged by an arm attached to means having no connection with the bucket, said arm serving to engage the said mechanism to open the bottom of the same, one of such arms being positioned at each unloading point.
The unloading mechanisms and the projecting arms may be varied in their location and relative positions so that certain buckets may pass certain unloading points without the arms at these points opening the buckets. 7
With the above and other ends in view the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims, reference being, had to the accompanying drawing, in which Figure 1 is a fragmentary side elevation of the present conveyer loading and unloading mechanism;
Fig. 2 is a transverse cross sectional view illustrating the bucket coming into contact with the unloading mechanism;
Fig. 3 is a transverse cross sectional View taken on the line 33 of Fig. 1, andFig. ,4 is a view similar to Fig. 2 illustrating another position of the unloading mechanism.
Like characters of reference are employed throughout to designate the corresponding parts.
The numeral 1 indicates an endless supporting rail of the i-beam type along which the trolleys 2"are propelled by means of the chain 3. Supported by elongated links ri are the buckets 5,
the links 4 being pivotally mounted or connected on the trolleys. The buckets are substantially V-shaped in cross section and are provided with a hinged wall 6 upon which is mounted a cross shaft 7 for supporting a pair of rollers 8 so that they extend outwardly from the sides of the bucket. The rigid end wall 9 has a pivotally mounted cross shaft 10 upon which is rigidly mounted a hook member 11 which engages the pivoted wall 6 to hold the latter in a closed position. The shaft also has a lever 12 rigidly mounted thereon ior rocking the shaft 10 and withdrawing the hook 11 from engagement with the pivoted wall 6 in a manner which will become apparent as the description progresses.
Mounted upon the links 4 are bearing members 13 which are engaged by the spaced guide rails 14 which are located'adjacent a loading chute 15. The manner in'which these guide rails 14 are supported forms no essential part of the present invention and has been left off the drawing for the sake of clarity and in order that a clear understanding of the invention might readily be had. a I
The links 4. support an outwardly projectin arm 16 which serves as a cam to engage an operating lever 17 on the chute opening mechanism 18, the guide members 14 serving to hold the links a so that the arm or cam 16 will engage the lever 17 and to prevent swaying of the bucket 5 when the material strikes it from the chute.
It is understood that a great number of buckets 5 may be supported upon the rail 1 and by -posi tioning the chutes on different sides of the bucket or with the operating lever 17 at dinerent distances laterally or vertically from the bucket, different materials may be loaded in different buckets positioned at various points along the conveyer merely by changing the position of the cam like lever or arm 16 so that it operates only a certain chute.
From the foregoing description it becomes apparent that the conveyer buckets 5 may be loaded with any reasonable number of difierent kinds of material and itwill also become obvious that the different materials should be unloaded at different points along the conveyer. The present invention provides for this by supporting guide rails 19 adjacent the unloading point by any suitable super structure and these rails are engaged by buffers 20 that are mounted on the sides of the buckets 5 in order to tilt the buckets to the position illustratedin Fig. 1.
When the bucket 5 has its buffers 20 sliding along the guide rails 19 the lever 12 is engaged by an upwardly projecting arm 21 which is rigidly mounted upon a rigid cross member 22 supported'in the dipped rails 23. The location of the lever 12'on the shaft 10 and the location of the arm 21 maybe varied in order that certain buckets may be unloaded at any suitable point and at the same time have loaded buckets pass the same point without being unloaded. The manner in which the location of lever 12 and arm 21 may be varied will be understood by comparing their respective positions in Figs. 2 'and' l, it being apparent that the lever 12 'as arranged in Fig. 2 will pass the arm 21 as arranged in Fig. 4 or vice versa without unloading the bucket.
The unloading is accomplished when the arms 21, which are selectively arranged, engages the lever 12 on the selected bucket, causing the shaft 10 to rock and withdraw the hook 11 out of engagement with the hinged wall 6, permitting it to drop so that the rollers 8 rest on the rails 23. As the bucket is propelled along the dip in the rails 23 permit the hinged wall 6 to fall away from the wall 9 and the material which is in the bucket falls therefrom. The continued movement of the bucket causes the rollers to pass along the dipped portion of the rails 23 to the higher portion which causes the hinged wall 6 to be moved to its closed position and the hook 11 hangs in its natural or normal position resulting from the natural forces of gravity wherein it engages the wall 6 to hold it in its closed position again.
It becomes apparent, therefore, from the foregoing description that the present invention provides a trolley conveyer which automatically re ceives and deposits a various number of selected materials at selected points along the conveyer and although a specific embodiment of the invention has been illustrated and described it is to be understood that various changes may be made within the scope of the appended claims without departing from the spirit of the invention, and such changes are contemplated.
