STATES rarest entice JOHN R. GRUETTER, OF CLEVELAND, OHIO, ASSIGNOR TO THE LIQUED CARBONIC COR- PORATION, OF CHICAGO, ILLINOIS, A COBPORATIQN OF DELAWARE BOTTLE-CHARGING MECHANISM Application filed September 14, 1929. Serial No. 392,663..

This invention relates to bottle-cleaning apparatus and more particularly to mechanism for charging series of bottles into series of bottle supports in such an apparatus. The invention is designed for usein bottle cleaning apparatus of the type wherein bottles are advanced intermittently through such apparatus while supported upon transverse series of seats, each series of seats forming across member of an endless conveyor.

It is the general purpose and'object of the invention to provide for bottle-cleaning mechanism employing such transverse series of bottle supports charging mechanism which will enable the bottles to be delivered into the successive series of supports with maximum rapidity and without danger of breakage.

Further and more limited objects of the invention will appear hereinafter and will be realized in and through the combinations of elements embodied in the claims and in and through the construction and arrangement of parts illustrated in the drawings wherein Fig. 1 represents a plan view of a portion of my charging mechanism; Fig. 2 a transverse sectional view through suchmechauism; Fig. 3 a longitudinal sectional view through such mechanism; Fig. 4 a detail in elevation of the main cam and the cooperating portions of the means for operating, the charging mechanism; Fig. 5 a similar View of the charging mechanism and the operating rods therefor; and Figs. 6, 7, 8 and 9 are diagrammatic sectional views showing the positions of the parts comprising my charging mechanism while completing a cycle of operations involved in receiving a series of bottles and delivering the same to a series of bottle supports.

Describing the various parts by reference characters, A (Fig. 5) denotes the front or receiving end a. bottle washing machine, the said machine having therein transverse series of bottle supports, indicated at B (see Figs. 6 to 9).

Secured to uprights A at the front of the main frame of the said apparatus are heavy brackets C. said brackets projecting forwardly from such end and providing a support for the bottle-charging mechanism and the front connections for operating the same. The charging mechanism comprises generally a table havinga transverse series of longitudinally extending grooves, the rear ends of which are arranged to register successively with transverse series of bottle supports or carriers B, as the latter are moved intermittently through the apparatus in the usual manner; a pivoted transfertray having grooves therein adapted to register at their rear ends with the front ends of the first mentioned grooves; a receiving platform on which the bottles to be loaded onto the tray are deposited and from which they are delivered onto said tray; a movable rack for delivering the bottles from said platform to said tray; and means for moving the bottles bodily from the transfer tray onto the grooves on the table and thence into the appropriate series of bottle carriers or supports.

The receiving and delivering table D is secured to and between'the front ends of a pair of arms E each pivoted adjacent toits front end on a shaft F and each having a slot E extending substantially the full length thereof, the front end of each slot being curved on a radius described from the center of the shaft F, fora purpose to be explained hereinafter. The front ends of the arms E are pivotally and adjustably supported from the brackets C by bolts E pivoted at their lower ends to lugs C and having their upper ends extending through slots E provided in lugs E extending laterally from the front ends of the arms E, each bolt E having adjusting nuts E thereon, located above and below the lug E.

The table D consists of a base D which is supported from the arms E by means of bottom cross membersD D resting upon lugs E E projecting from the bottoms of the arms E. The cross member D is in the shape of an angle bar, the vertical flange of which engages the vertical flanges depending from the forward ends of the lugs E the vertical flanges of said lugs having each a forward extension E which receives an adjusting screw E The base D may be of sheet metal, having applied to the upper surface thereof a plurality of truncated inverted V-shaped ribs D providing grooves D therebetween, the front ends of said ribs being beveled, as shown atD to facilitate the delivery of bottles thereinto from the swinging transfer tray.

Each arm E is pivotally mounted upon the shaft F by hubs E which are mounted upon a sleeve F rotatable on said shaft, the shaft being held against rotation by means 'of the set screws F The receiving and transfer tray consists of a base G having on the upper surface thereof a cushion G, of rubber or other suitable yieldable material, and on said cushion there is a series of longitudinally extending inverted truncated V-shaped ribs G preferably of wood, and providing grooves or chutes Gr therebetween which are adapted to receive the bottles H and to register at their rear ends with the front ends of the grooves or chutes D The tray is pivotally mounted upon the shaft by means of bracket arms G each having a split sleeve G at the bottom thereof whereby it may be clamped about the rotary sleeve F by a bolt G A tie rod Gr connects the rearward ends of the said bracket arms.

It will be noted that the rear end of the tray G is adjustably supported upon the tops of the screws E thus enabling the grooves or chutes G to be brought into register with the grooves or chutes D.

For the purpose of rotating the tray G, each bracket arm Gr is provided at its front end with an upwardly extending lug G in which is adjustably mounted a screw G which screws are adapted to be engaged by a cross bar J having its extreme ends mounted for reciprocationin slotsJ provided in the upper ends of rocking arms J 2 mounted on a shaft K.

G denotes an apron which is secured to inward extensions of the lugs G by means of bolts G extending through said lugs and a flange G on said apron see Figs. 1 and 3) The forwardly extending portion of this apron is curved on a radius described from the center of the shaft F and, when the tray 7 is in its delivering position as shown in Fig. 3, the lower end of this apron extends below the rear end of the receiving platform L.

V The platform referred to consists generally of a sheet metal base L having its on posite ends supported by cushions L of rubber or similar yielding material on seats C at the front ends of the bracket 0. The front is mounted a pad L of rubber or similar cushioning material, and the said pad in turn is covered by a thin. metal sheet L For the purpose of moving the bottles from the platform L to the tray G, I provide a rocking delivery rack having grooves for the bodies of the bottles and which rack is pivotally supported by arms so that, by moving the said arms the bottles will be swept rearwardly across the platform and deposited between the ribs upon the tray G. M denotes the arms, which are secured to the end portions of the shaft N, outside the brackets C. These arms extend upwardly and forwardly from the said shaft and have secured thereto a base plate M to which in turn a plurality of inverted'V-shaped ribs M are secured, providing grooves M therebetween for bottles the bottoms of which are deposited upon the platform L. Between the ribs M and the base M, there is inserted a metal sheet M having its upper end flanged, as shown at M and to which flange there is secured a transversely extending sill M the rear edge of which is adapted to engage the necks of the bottles, as indicated in Figs. 6 to 9 inclusive. A coiled spring 0, which is connected at one end with one of the arms M and at its opposite end with one of the uprights A, tends to rock the arms rearwardly or toward the transfer tray.

As is well known to those familiar with the art to which this invention relates, where conveyors having transverse series of bottle supports are advanced intermittently through bottle-cleaning apparatus, it is essential that the bottle-charging mechanism be so operated and so timed in operation that bottles will be delivered into each series of supports only when such series and the final r rocking arm K. This arm is provided in its upper end with a slot K in which is mounted a stud K and on the said stud is swiveled a sleeve K through which there extends a rod P having itsfront end threaded and provided thereon with a washer P and nuts P there being a coiled spring P interposed between the said washer and a washer P bearing against the rear end of the sleeve K". The rear portion of the rod P is threaded and is provided with an adjustable sleeve 1 thereon which maybe pinned at the proper point to the said rod whereby to transfer the forward movement of the said rod to the sleeve K and thence to the arm K and shaft K. i

P denotes a tubular extension of the P having its rear end provided with a threaded extension P which extension is threaded into a sleeve 1? which is rotatably mounted rod upon a stud Q/ in the lower end of an angle lever Q, the said lever being pivoted to a bracket Q on the side of the apparatus, the pivot being indicated at Q At the rear of said pivot, the angle lever is provided with a roller Q, which enters an appropriate track R in a cam R which is driven at the proper speed by a shaft S. It will be obvious that, by the rotation of the shaft S, the arms J will be rocked back and forth, thereby to reciprocate the cross bar J and to tilt the tray G in a manner to be described more particularly hereinafter.

For the purpose of rocking the arms M and the parts attached thereto, I have provided the shaft N with an arm N having a slot l 2 in the upper end thereof, within which slot there is mounted a stud T having a sleeve T mounted thereon into which is threaded the front end of a rod T The rear end of this rod is connected with one arm U of a bell crank lever, the said arm and the arm U of said lever being pivoted upon a stud U and the upper end of the arm U being provided with a roller U engaging the outer surface of a cam track R on the cam R.

It will be evident that the spring O maintains the roller U in contact with the exterior cam R during the movements of the rocking transfer-frame to which the arms M are attached. In like manner the spring P serves to hold the roller Q against the outer surface of the track R.

l/Vith the parts constructed and arranged as described, the operation will be readily understood. The cam R will be rotated by the shaft S, which, in bottle-cleaning apparatus of the type with which this charging mechanism is to be employed, will be driven in timed relation with respect to the means for feeding the bottle supports intermittently and in timed relation with respect to the other movable means which operate upon-the bottles in transit. The rotation of the cam will reciprocate the rods P and T in the manner described; and the rod T will oscillate the bottle-delivery tray MM to deliver the bottles onto the transfer tray G, while the rod 1? will oscillate the said tray.

The parts will be so timed that, when the operator has placed the bottles by hand on the platform L, with their sides resting in the grooves M and their necks engaged by the bars M the tray G will have been swung forwardly to the position shown in Fig. 6. The rod J, through its engagement with the screws G", will have rocked the tray G to the inclined position shown in this figure, the rod J being adjacent to the bottoms of the slots E. v The rotation of the cam will then cause the arms M to rock rearwardly, moving the bottles across the platform and delivering them with their bottoms upon the rod J and their rear sides resting in the grooves provided therefor in the upwardly and rearwardly inclined tray G-see Figs. 6 and 7 A further rotation of the cam will move the tray M, M forwardly to its receivingposition and will also rock the tray G to its horizontal or delivering position (see Fig. 8). A still further rotation of the cam will move the arms J rearwardly, thereby causing the rodJ to push the bottles along the table D and into the transverse series of bottle holders B in line therewith.

Following this operation, the cycle will be repeated, the conveyor of which the bottle holders form a part having been advanced onestep to bring into-receiving position the transverse series of bottle holders next adjacent the one just loaded.

Referenece has been made hereinbefo-re to the apron G This apron closes the gap be tween the rear end of the platformL and the front end of the tray G when the latter is in its deliveringposition; and it also serves to close this gap during the rocking of the tray upon the shaft F'when it is being swung toreceiving and delivering positions, It thus serves to prevent any material from entering the space between the tray G and platform L and from thus interfering with the operation of the said tray.

By the construction and'arrangement of parts and the mode of operating the same, I have produced a bottle-charging mechanism which can be operated at :relatively high speed and one wherein the 'danger of breaking the bottles during suchv operation is reduced to a minimum. This reduction of breakage is due, not only to the cushioned construction of the receiving platform L and the cushioned construction of the transfer tray G, but to the-employment of the springs O and P The former spring serves to maintain the roller U in contact with the cam R thus permitting the cam'to move away from the roller in the event that there should be any blocking of the movement of the tray M. The spring P permits the link 1? to be moved rearwardlywithout movement of the lever J and the rod J in case of an obstruction to the movement of, the bottles by saidrod and without danger of breakage'to the bottlesdue to such obstruction. r 1
