Application led August' 6, 192%. No. 1273er.

rlhis invention relates to bottle cleaning apparatus of the type wherein the bottles to be cleaned are carried on a transverse series of supports or seats, the said supports or seats being secured to side chains and constituting, with said chains, an endless conveyor that is driven intermittently, thereby to bring the series of bottles successively in operative relation tov transversely arranged cleaning mechanism, such as pressure-rinsing jets, and brushes for operating upon the interiors of the bottles. An apparatus of this character is shown in the patent granted to myself and John R. Gruetter on or about l5 August 19, 1919, No.- 1,313,706.

lit is the general purpose and object of this invention to provide, for bottle washin apparatus having a conveyor provided wit such transverse series of bottle supports or seats, charging mechanism which is adapted to deliver bottles to the said seats, without danger of breakage; which will act automatically to efi'ect such delivery at such predetermined time intervals as will enable several transverse series of seats to be charged at the same time and without interference with the intermittent operation of the conveyor; which will reduce to a minimum the danger of breaking the bottles; and which will reduce to a minimum the labor required in so charging the bottles to the conveyor. Further and more limited objects of the invention will be explained hereinafter and will be realized in and through the construction Y and arrangement of parts shown in the dra-wings, wherein Fig. `1 represents aside elevation, with parts broken away, of the rear of a bottle washing apparatus of the character referred to, having my invention incorporated therewith; and Fig. 2 a detail in section corresponding substantially to the line 2-2 of Fig. 1.

Describing the parts by reference characters, 1 denotes the rear part of the casing of a bottle-cleaning machine, the same being preferably of the general type shown in the patent referred to hereinbefore. 2 denotes a shaft extending transversely of the casing anddriving, by means of a crank disk 3, link 4 and arm 5, a transverse rock shaft 6. An arm 7 is secured to the roclrshaft, near each side thereof, and each such arm is connected by a link f with a rod 9, each of the rods being. provided with pawls (one of which'is indicated at 10), which pawls are adapted to engage shoulders 1la on the side plates 11 of the conveyor chains. rfhis construction for intermittently advancing the conveyor is shown and described in detail in the patent referred to hereinbefore.

The conveyor side chains formed by the side plates 11 and pintles l2 are carried by rollers 13 on the angular tracks M, as is the case with the construction shown in the aforesaid patent. lllhe side chains form supports for the transversely` extending rows of bottle seats or carriers, one such row being shown in section in Fig. 2. IThe particular seats as shown herein consist each of a sleeve 15 having its upper or receiving end 15 dared and having a contracted neck lh which is adapted to receive the breast of a bottle 16. The bottle seats comprised in each transverse series are mounted in a frame having an upper plate 17 and a lower plate 17 the said plates having openings i'or the bottle seats. rEhe plates 17 and 17 are connected by side plates 18, each having an ear 18a by means of which it is secured by a rivet 19 to the horizontal branch of an angular connector 20, the vertical branch of which is secured to the pintle 12. y

The sprockets (not shown) at the rear of the apparatus are so arranged that the portion of the conveyor which extends between the bottom and top of the rear of the casing is inclined upwardly. Above such inclined portion and extending rearwardly therefrom is a charging hopper. This hopper has an upper portion A and a lower portion B. The top and bottom sides of the part A converge upwardly so as to correspond in width with a crate C from which the bottles are dumped into the upper section of the hopper. The top and bottom sides of the art B are preferably parallel, as shown. ne space within the hopper A, B, is divided bypartitions 21 into transversely extending chutes 2&2

for the bottles discharged from the crate. It w1ll` benoted that the partitions in the upper part A of the hopper diverge somewhat from the top of the part A to the bottomV 5 thereof, being widest at the bottom, suchA width bein equal to the width of the chutes formed in t e part B. This widening of the chutes in thev part B is to insure registration of the bottles in the said chutes with the l0 seats 16 in the part of the conveyor therebeneath. The hopper section Bis provided, above the bottom of each chute 22, with a trap door 23, the trap doors in each transverse series of chutes being connected by straps 23 with a shaft 24. Connected wit one end of each shaft 24 is a rock arm 25 having its lower end provided with a pin 25* which is inserted within a slot 26* in the upper end of a short arm 26 the bottom of which is mounted on a rod 27 by means of a fork 26b on the bottom of the arm 26 and a bolt 23 clamping said forks against the said rod. The rod 27 is slidably mounted in sleeves 29 and 30 which are carried by bracket arms 31, 32 respectively. The former bracket arm is carried by the casing D and has secured to the upper end thereof a strap 33 forming part of the means for supporting the hopper from the casing. 34 denotes an arm which is secured to a rail 35 of the frame work for the apparatus, the said arm supporting a strap vided with transverse extending series of v 36 which assists in carrying the hopper.

The lower end of the rod 27 is provided with an abutment 27a between which and the sleeve 30 there is interposed a coiled spring 37 which tends to force the rod downwardly. Below the abutment 37 a roller 38 is carried by the forked lower end of the rod, the said roller being arranged to engage a cam 39 mounted on a shaft 40. This shaft .is supported in suitable brackets, one of which is indicated at 41, and'is provided with a bevel' gear 42 which meshes with a bevel gear 43 on a shaft 44 having at its opposite end a bevel gear 45 meshing with a bevel gear 46 on a 'transverse shaft 47, which transverse shaft is driven from the shaft 2 by means 0f a sprocket 48 on the shaft 2, a sprocket 49 on the shaft- 47, and a chain 50. The chain-andsprocket connection between the shafts 2 and l 47 effects a s eed-reducing drive between the shafts where y' the shaft 47 4will be driven preferably at one-quarter the speed of shaft 2.

E denotes a frame work at the rear of the apparatus, which frame work supports a se# ries of rollers 51 upon whichthe crates C may be moved until they are aligned successively with the hopper A, B. When so aligned or 535. Projecting from the bottom member 54 of the frame F is an arm 54 having a rearwardly extending latch surface 54".

Carried by the frame work E is a pivot Ez for a bell-crank lever one arm 60 whereof is provided with a roller 61 engaged by the cam 39 and the other arm 60'* isl connected by a link 62 with the `lower end of a lever 63 which is pivoted intermediate its ends at 63 from a bracket E, the upper end of the lever being provided with 'a look 64 adapted to engage the latch 54". A spring 64 tends to hold the lever 63 in latch-engaging position. A bellcrank lever is also pivoted at 63, the said lever having an upper arm 65 provided with a hook 65 adapted to engage the latch 54b while the other arm 66 is connected by link 67 with a pedal lever 68, the front end of which is pivoted to the frame E at E4. A spring 69 tends to hold the hook 65*L in engagement with the latch 541.

lt will be noted that each crate C is prochutes or compartments 70 for the reception of bottles from which chutes or compartments the bottles are adapted to be discharged into the upper portion A of the hopper.

With the parts constructed and arranged l frame F, the operator secures the crate within y the frame by means of the catch 59. The hook 64 normally engages the latch 54h, whereby the frame F, containing the crate C, cannot be swung into register with the hopper A, B, until-permitted to do so by the action of the cam 39. When this occurs and when the cam 39 shall have rocked the bell crank 60, 60a to disengage the hook 64 from the latch 54", the operator depresses the pedal lever 68, thereby releasing the additional hook 65a and then can swing the frame F and the crate C therein about its pivot on the part E', the lifting of the crate being facilitated by the counterweight 58. When the crate and frame are in the position shown in dot-and-dash lines in,

Fig. 1, the ltop of the crate will be supported by the band 71 around the top of the hopper while the bottles slide down the chutes 22 until -their mouths contact with the trap doors. The inclination of the chutes, taken with the doors 23, revents injury to the bottles bydropping rom thecrate into the hopper. When theconveyor shall have advanced a sufficient distance to move the reary most series of bottles `therenout of register with the uppermost-transverse series of chute in the hopdper, the cam 39 will thrust the rod. 27 upwar y, thereby rocking the shafts 24- to move the trap doors downwardly and permit the bottles to drop into their seats. When the cam shall have traveled' a suicient distance, the roller 38 will ride od the high part of the cam and the spring 37 will move the said'rod downwardly, thereby closing the trap doors. The operator can swing the trame F and crate C downwardly and remove the crate and insert another one ier the next operation.

By reason of the construction and arrangement of the parts shown herein, one person can move the crates into register with the charging hopper; can inspect the bottles in the crate; can clamp the crate to its tilting frame F; can swing the crate up to its discharging position; can return the frame and crate to the full-line position shown in Fig. 1; and can remove the crate from the frame, so that the operation may be repeated. Furthermore, the provision of the trap doors 23 and of the means ior'operating the same prevents the breaking of the bottles by dropping entirely through the hopper into their seats in the conveyor and also prevents the dropping of bottles from the hopper against bottles in the conveyor seats. An additional feature of safety resides in the use of the two catches or hooks for the latch 54". While the operator can, ofcourse, release his hook a at any time by merely pushing down upon the pedal lever 68, the crate C and frame F cannot bel swung upwardly to discharging position u-ntil the cam 39 shall have operated the catch 64:;l and this operation will not be permitted until the cam shall have permitted the doors 23 to be closed by the rod 27 and spring 37, which will prevent the dropping of the bottles from their chutes in the crate, Without checking, into the seats in the conveyor' and a further feature of safety resides 1n the fact that the doors 23 will not be opened by the cam until the conveyor shall' have been advanced a sufficient distance to insure that no bottle-occupiedseries .of seats 16 will be in register with a series of chutes in the hopper A, B.

The charging mechanism as a whole is comparatively inexpensive of construction and is capable of being installed conveniently on existing conveyor-type'of bottle-washing machines. 1
