This invention relates to an improvement in conveyer mechanism more particularly in such mechanism of the live miler type comprising a plurality of article transporting rollers rotated 5 by a driving cable. Objects of this invention are briefly to provide in a live roller conveyer mechanism, means for tently. 'I'he branch line |0| may be of any de sired type and is here shown as a gravity roller conveyer having a plurality of free rollers over which the articles travel. Suitably supported across the main line as upon uprights |02 are _a UI pair of angle bars |03, one at each end of the junction of the main line with the branch line. deflecting articles from the main line to a branch Mounted at their ends upon the bars |03 are a line and automatic means for facilitating the . channel bar |04, an angle bar |05, and a rod |00, the bars |04 and.` |05 and the rod |06 being all l0 separation of the articles into groups. lThese-and other objects of the invention will parallel to each other as shown particularly in be fully understood from an examination of the Fig. 1. Between the cross bars |03 are mounted following detailed description thereof and of the the live rollers | 01, hereinbelow referred to as de drawings which form a part of said description ilector, rollers. Each roller |01 is carried by a U-shaped bracket |08 in the end walls oi which -o and in which Fig. 1 is an enlarged plan view of a live roller the vroller is rotatably mounted. Each bracket |08 is pivoted upon the bar |04 by a pin |08 and section 'provided with an article deiìector mecha is supported at one end by an ~antifriction bearing nism embodying this invention; ||0 which surrounds the pin | 09 and at the otherFigs. 2 and 3 are side elevation and cross-sec end by the ma los upon-which it rests freely. As20 tional views respectively thereof; Figs. 4 and 5 are enlarged views partly in cross sociated with each roller |01 is a sheave III > mounted upon the bar |05 by a bracket | |2. Each section of details of the deilector mechanism; Fig. 6 is a diagrammatic view illustrating the sheave III holds the cable 52 in contact with its roller |01 and is so positioned over the pivot pin operating circuit for the deflector mechanism; |00 that the contact of the cable and the roller 25 Figs. '1, 8, and 9 are side elevation, cross-sec tional and plan views respectively of an article is in vertical alignment with the` pin. As indicated by dotted lines on Fig. 1 the actuated control for separator mechanism; Figs. 10 and 11 illustrate the article contacting brackets |00 with the rollers |01 are movable upon the pivot pins |09 to guide articles from the main arm of such control; Fig. 12 is an enlarged sectional view of a detail line to the branch line |0I. The brackets are moved in unison being connected at the ends fur of the arm shown in Figs. 10 and 11. Fig. 13 is a view in elevation oi' the ratchet thest from the pins |09 by straps which vary in length as shown particularly in Fig. 1. The iive wheel of the control; A Fig. 14 is a view of electrical element of the brackets at the right end of the group are joined by a single strap | I3 so that they move a uniform control; and" Fig. 15 is a diagrammatic view illustrating an distance. 'I'he other brackets move distances electrical layout by which the control is caused which gradually decrease, the sixth bracket from the right moving a shorter distance than the five to operate a deilector mechanism. This invention relates to a conveyer system brackets which are joined together and the 40 which includes one or more live roller sections. bracket atl the left end of the group moving the 'I'he term “live roller section” is used to designate shortest distance. This follows by reason of the difference in length of the straps Ill, H5, H6, a conveying instrumentality comprising a plural I I1, ||8 and ||0 which respectively join the adja ity of rollers over which the articles travel and a cable'or the like which is held in contact with the cent brackets. The manner of pivotally securing rollers and driven by a motor or other means to the straps to the brackets is illustrated in Fig. 5 rotate the rollers and cause the latter to advance which shows a pin |20 by which one end of the the articles. In Fig. 1 which illustrates a portion strap ||4V is secured to a bracket |08. Movement is imparted to the brackets |00 by ' of a conveyer system is shown a live roller sec 50 tion comprising a plurality of rollers |01 rotated a thruster |25 of the well known type having by a suitably advanced cable 52. n The live roller section indicated on Fig. 1 in cludes a branch station or storage line |0| leav ing from the main line- and to which articles are ~515 'deñected as' desired either continually or intermit 10 15 20 N5 30 35 ' “o ‘5 50 push rods |26 connected by a cross bar |21 which is raised and lowered by the mechanism within the thruster which is not shown'being norpart of the present invention. A cross shaft |25 ' - mounted upon a pair of uprights |02 is oscillated g5 l.“n i .at » , by the thruster through an arm it@ pivotally at tached to the cross bar 521’. This movement' of the shaft 926 is transmitted to the brackets mit through an arm it@ fixed at one end; of the shaft, 'a link; liti ancla strap i152 fined to one oi’ the brackets "|06, A spring itil iìxed at one end to a cross bar lilil and at the other end to a bracket i08 assists the thruster to return the rollers lil'i to the normal position shown in full lines in 10 Fig. 1 so that articles will pass undeflected. along the main line. The thruster |25 hereshown is electrically op erated by an electric circuit, such, for example, as that shown diagrammatically in Fig. 6. Mounted upon one side rail of the main line and in the branch line ||l| are circuit breakers |35, |36 and |31 respectively. The' breaker |35 on the main line serves as a safety device and when tripped by contact with an article opens the cir 20 cuit. The breakers |36 and |31 are arranged in parallel and both must be tripped simulta neously to open the circuit. The breaker |35 is so located that it will be tripped by each article on the _main line passing over the deilector junc 25 tion so that the circuit may not be inadvertently closed and the brackets |08 swung on their pivots when an article is entirely supported by the de flector rollers |01. A switch |38 operable man ually or in any well known manner controls the 30 state of the circuit (either open or closed) in the usual way. Figs. 7 to 15 illustrate means for energizing the thruster |25 which may be employed When ever it is desired that alternate groups continue 35 their travel past the deilector mechanism along the main line, and that the other groups be de ilected to the branch line. The groups each con sist of a predetermined number of articles, which may diii‘er between the main line groups and the 40 branch line groups. For example as will ’he pointed out below, the illustrated separating means may make main line groups consisting of ñve articles each and branch line groups consist ing of three articles each. 45 'I’he separator |52 operates automatically and comprises the following , aise, « instrumentalities. Mounted upon a structure which comprises up rights |53 at opposite sides of the live rollers and an overhead frame |54 above the rollers and 50 formed by angle bars, is a shaft |55 which is freely rotatable in journal bearings |56. Fixed to the shaft |55 is a ratchet wheel |51 with which a pawl |58 carried by a guard |59 meshes. Sus pended from and freely movable about the shaft 55 |55 are a pair of arms |60 one ateither side of the ratchet wheel |51. The arms are of such length that a bar |6| carried by the lower ends Itfi'ountezi on the frame tilt is control bon il@ within which is mounted a rotor Il’i'il fined at one enti of the shaft and a pair of wiper arms ill@ mounted upon blocks of dielectric mate rial i‘lii. :rotor is also primarily of dielectric material having, at diametrically opposite sides of the periphery, Contact plates i'ih’l. The tipa of the Wiper crine i12 .are yieldably held by springs i'iil in Contact with the periphery of the rotor. The rotor is advanced step by step in unison with 10 the ratchet wheel. In the illustrated construction the wheel includes sixteen teeth so that the pas sage of sixteen articles will cause one complete rotation of the wheel and of the rotor. 'I'he ‘con tact plates |14 are of such length that the wiper arms |12 will remain in contact therewith while ' ' the ratchet wheel is moved three steps. Thus after three articles have passed the arms contact with the dielectric portions of the periphery o1' the rotor until ñve more have passed. thruster |26 as shown in Fig. 15. Thus the thruster will be energized while groups of three articles pass the separator and deenergized while groups of ñve articles pass so that groups of three 25 are deflected and groups of five are not. The number of articles in the groups obviously de pends upon various details as for example the number of teeth in the ratchet wheel and the number and length of the contact plates |14 of the 80 rotor, which may be changed to suit the desired requirements of any installation. While certain features of this invention have been shown and described in detail it will be un derstood that the invention is not limited thereto 35 and that various changes may be made in any or all thereof without departing from the spirit and scope of this invention.
