EHILADELPHIA, PENNSYLVANIA, ASSIGNOBS TO THE LAIMSON COMPANY, OF SYRA- CUSE, NEW YORK, A CORPORATION OF MASSACHUSETTS GONVEYER Application filed April 22,

This invention relates to an improvement in conveyers and more particularly to the provision of means for delivering to a. main conveyer a plurality of load units supplied by several branch conveyers.

Theprimary object'of the invention is to provide means which insures that the load units delivered to the main conveyer by each branch conveyer are spaced a predetermined distance apart to permit the delivery to the main conveyer of load units from other branch conveyers without danger of 00111- sion. A further object of the invention is to provide means associated with each branch eonve er for stopping at regular intervals the travel of the load units fed thereby, such means being controlled by mechanism so that they function alternatively, whereby the load unit on one branch conveyer only travels and the unit on the other branch conveyers are at rest.

Another object of the invention is to provide a conveyer comprising two article transporting sections and a movable section nterposed between the first two whichsection in one position receives a predetermlned load unit from one section and in another position delivers such load unit to the other section in combination with a stop associated with the movable section and movable relativethereto and means for actuating the movable section and stop. Other objects of the invention will appear from an examination of the following specification and of the drawings which form a part thereof wherein one embodiment of this invention is set forth for purpose of illustration. The embodiment of the invention selected for illustration comprises two branch conveyers by which boxes are delivered to a main conveyor but it will be understood that the number of branch conveyers maybe changed and that the illustrated embodiment may be altered in various respects without departing from the spirit and scope of the invention as hereinafter described.

branch conveyers taken along the line 2 -2 of Fig. 1; and

Figs. 3 and 4 are side elevations of certain elements of one of the branch 'conveyers, said elements being shown in Fig. 3 with the load units at rest, and in Fig. 4 with one load unit 7 .This invention embodies broadly a main conveyer A and a pair of branchconveyers B and C by which boxes are delivered to the main conveyer. The conveyer A may be of any desired type and is here shown as a belt conveyer- Which travels in either direction as indicated by the double-headed arrow on Fig. 1. The belt 10 of the selected main conveyer passes over a plurality of rollers 11 in the usual manner and is driven by a motor or other suitable source of supply (not shown).

Side walls

12 and 13 are provided between which the conveyer belt 10 passes.

The side Wall 12 comprises a suitably sup ported angle bar on the flange 14 of which one edge of the belt 10 travels. The edge of the belt 10 adjacent the branch conveyers travels over the flange 15 of a suitably supported angle bar 16. The side wall 13 is made in sections which also act as side walls for the branchjconveyers B and C (see Fig. 1).

The branch conveyers B and G are similar in construction and differ from each other merely by reason of the fact that they are intended to handle boxes of diflerent izes. Each branch conveyer embodies a belt sec- .tion a movable section and an inclined'seca gear reduction mechanism 29 so that the travel of the belts 20 in both branch conveyers is-at a uniform rate. I V

The movable conveyer section 30 comprises aplurality ofrotatably supported rollers v31 carried by flange side bars 32. The

bars 32 are suitably connected and pivotally mounted upon stud shafts 33 at their forward ends and rest upon cams 34 carried by a shaft 35. he shaft 35 is preferably made in two sections connected by a universal joint 36 and is driven from the conveyer.

roller 22 in the following manner. Mounted upon one end of the shaft 37 which carries the roller 22 of branch conveyer B is a pinion 38 which meshes with a gear wheel 39 fixed at one end of a shaft 40 suitably supported in the frame below and parallel to the shaft 37, and having at its other end a pulley 41 which, through a belt 42, drives a pulley 43 mounted on the end of the shaft 35. It will be noted that while the shaft 35 is made in two sections the connection 36 insures their uniform rotation. The cams 34 are so positioned upon the shaft 35 that movable section of the other conveyer is.

lowered. Thus, the positions shown in Figs. 2 and 4 take place simultaneously. Interposed between the movable section 30 and the belt section is a stop 45 formed by one end of a strap 46. The other end 47 of the strap is fixed upon a roclr shaft 48 mounted in bearings 49 carried by the frame 50 on which the section 30 is supported. The shaft 48 is preferably rectangular in cross section except at the ends where it is cylindrical and is supported in the bearings 49. The end 47 of the strap 46 may be bent around the rectangular section of the shaft 48 and secured by a set screw 51. The shaft 48 is rocked by'and in unison with the movable section by an arm 52 fixed at one end to the shaft and having at its other end a slot 53 which receives the end of a cross rod 54 carried by the side rails 32.

The boxes are fed onto the movable section 30 by an inclined section 60. This section preferably acts through the force of gravity to advance the bones and may be of any desired type. As here shown the sec tion comprises suitably supported. flanged rails 61 which carry freely rotatable rollers 62 and side rails 63. The sections 60 may be of any desired length and the boxes be delivered thereto in any well known manner. It will be apparent that when the movable section 30 is raised as shown in Fig. 4 the free end thereof will prevent the travel of any boxes from the section 60 and thus functions as a stop. The movable section 30 is of such length that it will support at one time only one-box.

The operation of the branch conveyors will now be described with parti ular reference to Figs. 3 and 4 of the drawings wherein the movable section 30 and stop 45 of the branch conveyer C are shown in the two extreme, positions which they are caused to occupy by the rotation of the shaft 35. As shown in Fig. 3 when the section 30 isin the plane of the belt 20 the stop 45 projects into the path of travel of the box 65 and holds it upon the section 30. As the shaft 35 is rotated, however, the cams 34 raise the section 30 011 its pivot pins 33 and at the same time through the action of the arm 52 and shaft 48 the stop 45 will be lowered so that the box 65 on the section 30 which has been checked by the stop 45 will now be released and allowed to slide onto the belt 20. The section 30 in its raised position, (see Fig. 4) acts as a gravity conveyer and the box supported thereon advances without further attention to the belt 20. The free end of the movable section, however, eXtends into the way of any boxes which may be passing down the in clined section 60 and stops their progress. /Vhen'thesection 30 returns to the 3 position, the boxes on the section 60 are then free to advance onto the section 30 until the leading box comes into contact with the stop 45. The cams controlling the section 30 of the branch conveyer B are arranged diametrically with respect to the cams 34 which control the section 30 of the conveyer C. As a result, when the section 30 of one conveyer is raised and its box passed to the belt 20, the section 30 of the other conveyer is receiving its box and at the same time the stop 45 of the first conveyer will be inoperative to permit the box to pass while the stop 45 of the other conveyer will be operative to check the box on the section 30.

One purpose of this invention is to provide an article transporting conveyer to which articles may be supplied in convenient amounts with the assurance that they will be delivered at intervals either individually or in groups of any predetermined number. Thus the articles may be delivered onto the inclined section 60 but by the operation of the movable section 30 and the stop 45 they will be automatically separated and be delivered from i the conveyer by the belt 20 at regularly spaced The broad advantages flowing intervals. from this construction whereby a regular supply of articles of any size or dimensions is assured without the necessity of any handling after thearticles are first fed into the conveyer are obvious and need not be particularly specified.

Another purpose of this construction resides in the feeding of the load units to the main conveyer A and in view of the construction just described it will be obvious that the units from each branch conveyer advance at regular intervals to the main conveyer and consequently when delivered onto the main conveyer are at a predetermined distance apart. Furthermore it will be apparent that ered by the belt 20 of the other branch conveyer. The operation of these conveyers is so timed that each unit delivered by the second acting branch conveyer enters'the main conveyer at the space provided between the units delivered by the first acting branch conveyor, and there is no danger of any collision which would interfere in any way with the operation of the main conveyer.

While the conveyers of the illustratedembodiment are intended to handle boxes of different sizes it will be understood that this invention is not limited thereto and consequently in the claims the term load units has been employed to designate the articles delivered by the branch conveyers which articles may be supplied either singly or in grou s.

It will be understood that the particular type of conveyers shown and described as A, B and C were merely selected for the purpose of illustration and that other types of conveyers could be substituted therefor without independent of the main conveyer for operating the branch conveyers and means actuated seriatlm by said first named means for regulating the feeding operations of the branch conveyers which means includes a movable section of each branch conveyer, and means for shifting said sections alternately out of position and thereby stopping the feeding operations.
