CAN-DISCHARGING MECHANISM FOR CAN-WASHING MACHINES.

Specification of Letters Iatent.

Patented Jan. 8, 1911.8.

Application filed June 9,1917. Serial No. 173,896.

To all whom it may concern) Be it known that we, HARRY D. LATHROP and VVALTER H. PAULSON, citizens of the United States, and residents of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Can-Discharging Mechanism for Can-Washing Machines, of which the following is a specification.

Our invention relates to improvements in milk can washing machines, and has for its object the provision of improved means for discharging milk cans from a machine of the character mentioned.

In the operation of milk can washing machines involving an inclined guide down which the cans-travel after reversal of the same and at the time of application of the and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a longitudinal sectional view through the discharge end of a milk can washing machine, equipped with discharging mechanism embodying the invention,

Fig. 2, avertical transverse section taken on substantially line 2-2 of Fig. 3,

Fig. 3, a horizontal section through the discharge end of the-machine, and

Fig. 4, a side elevation of a portion of the construction seen in Fig. 2. I

The preferred form of construction, as illustrated in the drawings, is designed for use in connection with a can washing machine involving a suitable framework 5 in the lower portion of which is arranged a guide 6 for the support of the milk cans in the passage or sliding of the same through the machine, the cans during their move-' ment upon the guide 6, being subjected to the various cleaning or washing processes as d is known by those skilled in the art.

The cans, in passing along the guide 6, are. arranged in inverted position, and in order to efiectreversal of the. cans before the discharge of the same from the machine,

an oscillatory can reversing device 7 is pro vided at the discharge end of said guide, said reversing device being pivotally mounted on trunnions 8. The arrangement is such that as the cans are successively pushed from the guide 6, the same will drop into the device 7 and be reversed thereby and deposited onto an inclined guide 9 down which each can, designated by A, slides by gravity.

Just after each can has been deposited onto the guide 9 and started sliding down the same, the can is arrested in its movement by an arm 10 to permit of application of the cover of the can thereto, this cover applying mechanism being covered in a se arate application filed June 9, 1917, erial No. 173,897, so that a detailed description of the same at this time is unnecessary. The arm 10 is pivoted at 11 and is adapted to traverse the path of the can in front of the latter. Said arm is formed with an outwardly projecting portion which extends through an elongated slot 12 in a plate 13 carried by a reciprocatory actuating bar 14, as clearly seen in Fig. 4:. The arrangement is such as will be seen, that rocking of the arm 10 to arrest or release a can is effected through reciprocation of the bar 14, said arm being f course rocked to traversing position upon forward movement of said bar, or to the left, as seen in Fig. 3, said arm being released to allow for continued movement of a can, upon movement of said bar in the opposite direction.

It has been found that after thus arresting the movement of a can, the latter does not start to move fast enough of its own weight, frequently resulting in a can being in the way of the succeeding can, that is in clogging the discharge guide 9.

In order to positively prevent this clogging, an arm 15 is provided, arranged at the side of guide 9, and pivoted at 16 to permit of swinging of said am in a sub.- stantially horizontal plane across the ath of a can traveling down said guide 9. and arm 15, like the arm 10, is also formedwith an outward extension which engages 1n an elongated slot 17 formed in the plate 13 so that swinging of said arm 15 will also be controlled through reciprocation of bar 14:. The arrangement is such that, upon forward movement of bar 14', to the left as seen in Fig. 3, the arm 15 will be rocked to nontraversing or inoperative position, as seen in dotted lines in Fig. 3, and, upon movement of said bar in the opposite direction, said arm will be swung forwardly to traversing position, as seen 1n full lines in Fig. 3.

The arrangement is such that, in the operation of the machine, as a can starts down the guide, '9 after being deposited thereon from the reversing devlce 7, the same will be arrested by the arm 10, the arm 15, during this time, being in non-traversing or inoperative position. Upon release of the can, such as is effected through rearward movement of the bar 14, the arm 15 will be suddenly and violently swung out into engagement "with the rearward side of the can effecting thrusting or kicking of the can down said guide,-as will be readily understood. In this way, each can will be positively discharged from the machine before the succeeding can is deposited onto the discharge guide, insuring against interference between the cans or clogging of the discharge guide.

The slots 12 and 17 are'of proper lengths to secure the proper timing in the movement of the arms 10 and 15, and said arms are 'formed with stops 18 and 19 which are adapted to engage against the outer side of the plate 13 to limit rockin of said arms. While we have illustrate and described the preferred form of construction for carrying our invention mto efl 'ect, this is capable of variation and modification without departing from thespirit of the invention. We, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of such variations and modifications as come within the scope of the appended claims.

Having described our invention what we 1.-In a washin machine of the class described, the combination of a guide for the objects passed through the machine; an arm pivotally mounted intermediate its ends at one side of said guide whereby, through rocking, of said arm, one end thereof may be swung into engagement with an object on said guide to thrust the same along said guide; and means for rocking said arm comprising a reciprocatory member having an elongated slot therein engaged by one end of said arm, substantially as described.

2. In a washing machine of the class described, the combination of a guide for the objects passed through the machine; an arm pivotally mounted intermediate its ends at one side of said guide whereby, throughrocking of said arm, one end thereof may be swung into engagement with an object on said guide to thrust the same along said guide; means for rocking said arm comprising a reciprocatory member having an elongated slot therein engaged by one end of said arm; and a stop on said end of said arm adapted for engagement with said reciprocatory member for limiting -rocking movement of said arm, substantially as described.
