Risser, Chicago, Ill., assignor to U. S. Bottlers Machinery C0., Chicago, Ill., a corpo ration of Illinois Application January 23, 19-37, Serial No. 12:1,9-28 4 Claims. (Cl. 198-131) This invention relates to container conveying lower idler sprockets 6 and 'l at the left hand end apparatus, and more particularly pertains to such apparatus in connection with means for of the stretches, as seen in Fig. 1. The drive sprockets 5 are secured on a drive shaft 8 which treating bottles, such as bottle cleaning or wash is driven to intermittently advance the conveyor, Cil ing machines. so that the cleats 2 are moved from left to right Generally, the invention aims to provide im when in the upper stretch of the conveyor, by c1. proved bottle positioning or holding means for means of a rotating power shaft 9 on which is an such apparatus, wherein the possibility of break eccentric device l0, arranged to operate, through ing or otherwise damaging the bottles as they are a connecting rod II, an oscillating lever l2 ful fed to the apparatus, or carried thereby, or dis charged therefrom, is greatly eliminated. More particularly, the object is to provide the simplest and most inexpensive bottle positioning or holding means for intermittently driven bottle conveyors adapted to intermittently advance the bottles through the machine in inverted position, whereby the bottles will be resiliently held in such position on the conveyor by their necks without the possibility of the bottles breaking at the base of their neck portions by motion im parted thereto upon said movement of the con veyor. One of the advantages attained by the inven tion, is that frail bottles, such as those with long thin necks, may be intermittently advanced through the machine more rapidly than hereto fore made possible so that treatment of the bot tles will be expedited. Other objects and advantages will become ap parent by reference to the specification and the accompanying drawing, in which: Fig. l is a fragmentary side view of a bottle washing machine, showing one form of the in vention _applied thereto, with parts broken away and parts in section to more clearly disclose cer tain parts otherwise hidden. Fig. 2 is an enlarged detail plan section of Fig. 1, as may be taken substantially on the sec tion line 2-2 of said figure, with certain ele ments being omitted. Y Fig. y3 is a detail section taken substantially on the section line 3-3 of Fig. 2. Fig. 4 is an enlarged detail section taken sub stantially on the section line 4-4 of Fig. 3. Referring to Figs. l, 2 and 3, the Washing ma chine, generally illustrated for the purpose of this application, includes an endless bottle conveyor comprising a series of interconnected carrier members or cleats 2, in the form of channel 50 pieces, mounted at their ends upon links 3 of laterally spaced endless sprocket chains 4 which are arranged to travel in upper and lower hori zontal stretches by being trained over drive sprockets 5, respectively, at the right hand end 55 of the stretches, and supported over upper and crumed on the drive shaft 8 and having a weight~ ed pawl I4 for operating a ratchet wheel l5 fixed on the drive shaft 8. Each cleat is provided with a row of bottle re ceivers I6 for » receiving and supporting a row of bottles in inverted position upon the upper » stretch of the conveyor, and, as the cleats are about to be advanced into the upper stretch of the conveyor, the receivers thereon are brought into cooperative relation with a bottle feeder head Il arranged to automatically feed a row of bot tles thereto. Then as the transverse rows of bot tles are intermittently advanced on the conveyor they are brought into cooperative relation, suc cessively, over two liquid cleaner heads I3 and I9 0 which direct jets of water into the bottles to clean same. The cleaner heads are of common construc tion, comprising two laterally spaced pipes car rying water under pressure, and with each pipe having a row of upright nozzles 2li for directing the jets of Water into the bottles. . After passing over the cleaner heads the bot tles are caused to remain on the conveyor a suffi cient length of time in order that they may be properly drained before being discharged or 35 otherwise removed from the conveyor. Although the feeder head is of ordinary con struction, it may be stated that it comprises a shelf inclined downward toward the receiving end of the conveyor, and having a. series of laterally spaced troughs 2l within which the bottles are placed in reclining position with their necks pointing downward in register with a row of re ceivers I6 of a cleat, between each advance of the conveyor. Between the shelf and conveyor is a gate 22 for retaining the bottles in the troughs of the shelf while the conveyor is in mo tion, and being operably connected with the con veyor to be lowered so as to effect release of the bottles by force of gravity to the receivers i6 when the conveyor is at rest. The gate comprises an elongated arcuate segment having each end se cured to an oscillating bell-crank 23 which is operated, to raise and lower the gate as stated, 2,105,795 2 c by the power shaft 9 on which is a suitably formed cam 24 operating a lever 25 which is connected by a link 26 with a bell-crank 21 arranged to operate the bell-crank 23 through a link 28. In accordance with the main object of the in vention, the bottle receivers IB are formed and ar ranged to resiliently hold the bottles in position on the cleats of the conveyor by their necks. To this end, each receiver comprises an open-ended 10 pocket in the form of a tubular section of slightly Having thus described my invention, I claim: 1. The combination with a bottle conveyor, of a bottle receiving pocket therefor comprising a tubular portion of rubber adapted to receive the neck portion of a >bottle and having an integral flat mounting flange formed about its receiving end, the side-walls of the pocket being thinner than the flange whereby the pocket will be capa ble of a swivel-like action with respect to said flange, and the flange having its outer portion se cured to the conveyor whereby the inner portion of the flange adjacent the pocket will be capa resilient material, such as slightly resilient rub ber, which is adapted to snugly receive the neck , ble of flexing with respect to the conveyor when portion 29 of a bottle, and having its receiving end the pocket has been flexed or tilted beyond a cer tapered or countersunk, asl at 3B, providing a seat tain angle with respect to said inner portion of 15 for supporting the shoulder portion 3| of the bot the flange. ‘ tle adjacent its neck.
