. fication.

' is a side elevation of my improved machine This invention relates toan improved machine for washing and Scrubbing bottles and for soaking off the labels. The machine is so constructed that'the bottles, are automatically fed to the rinsing-drums, are washed at the interior and exterior, and are then emptied and scrubbed.

In the accompanying drawings, Figure 1 for washing bottles; Fig. 2, a plan of the same with the scrubber removed; Fig. 3, a cross-section through the drums; Fig. 4:, an enlarged section on line 4 4, Fig. 1; and Fig. 5, an enlarged plan of part of the scrubber.

The letter (1 represents the frame of the machine, carrying the bearings for the shafts b c of a pair of washing or rinsing drums b c. These.drums are hung parallel, the receiving-drum I) being arranged in close proximity to and slightly higher than the delivery-drum c. Each drumis divided by rectangular partitions into a number of pockets b 0 partly closed at the inner ends by cylindrical perforated walls b 0 while they are open at their outer ends. The drums b c dip with their lower sections into imperforate curved tanks or troughs d e, arranged concentrically to the drums-b c, respectively,

and directly beneath the same, so as to support the bottles contained within the immersed pockets.

Intermittent rotary motion in the same direction is imparted to both drums by power or hand, the drawings showing them to be operated by means of a hand-lever f, turning on fulcrum f and carrying pawl f which engages a pinion f This pinion meshes into a toothed wheel 0 fast on shaft 0 and intergeared with wheel b fast on shaft I), through intermediate wheel g. By means of the mechanism described each downstroke of the hand-lever will turn the drums c b in the direction of the arrows for the length of one pocket, while the drums will remain station-- ary during the upstroke of the lever.

In order to carry the bottles to the receiving-drum b, I provide a conveyer which'delivers the bottles to the drum 1) on the side opposite to drum 0. The frame of the con veyer is provided with an inclined upper run composed of a series of spaced parallel rails h and intervening grooves or guideways h, along which the bottles A are adapted to be moved. The number and arrangement of the grooves correspond to the number and arrangement of one transverse row of pockets b so that each groove h will deliver its hottle to that one of thepockets with which it is .in alinement.

In'order to feed the bottles along the run, I employ endless chains i,passing over sprocket wheels 'i 11 The chains are provided at suitable intervals with upwardly-extending pins 11 connected by transverse rods t. These rods are adapted to engage the bottoms of the bottles A within grooves h and to thus feed the bottles from the lower end of the conveyer toward drum 1). The upper ends of the rails h are curved downward, as at 71. to conduct the bottles from the conveyer to the pockets. Intermittent movement is imparted to the chains in such a manner that the chains are in motion when the drum is at rest, and vice versa. The means shown impart this movement to the chains by the handlever f and consist ofa ratchet-wheel i fast on shaft 71 of sprocket-wheel t. The ratchetwheel 2' is engaged by a pawl j, pivoted to an angle-lever j, that turns loosely on shaft 2' and is connected to lever f by rod 3' bellcrank 9' and rod j.

As the bottles are being carried up along the conveyer they are subjected to a preliminary heating, which guards them against cracking when immersed into the hot water of tank d. This preliminary heating is efis in alinement with one of the pockets 0 The shafts Z of rollers l are hung in crossbars a of frame a and receive continuous rotary motion from a pulley on through wormshaft m and worm-wheels Z fast on shafts l. Transversely across the rollers 1 extends a cylindrical rotary brush 'n, driven from shaft m through wheels m, n, and belt 013. A suitable sprinkler n throws water upon the bottles and the brush. From the rollers Z the bottles are removed by a conveyer composed of endless chains 0, engaged by sprocketwheels 0' o and provided with cross-bars 0 by which the bottles are fed forward.

Intermittent movement is imparted to the chains 0 simultaneously with the chains 1:, so that both sets of chains are moved While the drums are arrested, and vice versa. I The means for operating chains 0 are shown to consist of a ratchet-wheel 0 fast on shaft 0 of sprocket-wheel 0. The ratchet-wheel o is engaged by pawl 19 of a lever 10, which is connected to bell-crank j by rod 10 The operation is as follows: The bottles A are placed on the guideways hv of the conveyer, and as the hand-lever f is raised the foremost row of bottles will be discharged into one row of the pockets b their necks poiutinginward. The hand-lever is then depressed so as to turn the drums for the space of one pocket, and this operation is repeated, so that all the rows of pockets 1) are successively charged. As the bottles pass through the hot water of tank at they become filled, so that their interior and exterior are washed. When a row of pockets has cleared the tank (1, its bottles will slide into the pockets 0 of drum 0, but will become reversed, Fig. 3. The drum 0 willdraw the reversed bottles through the water of tank e, the water within the bottles being freely discharged as soon as their necks are elevated above the water-level. The reversed and emptied bottles are delivered from drum 0 upon the rotary rollers Z, which expose their entire surface to the action of the brush n. This brush serves to remove any adhesive dirt or labels which may still be present. The cleaned and rinsed bottles are finally discharged by the chain conveyers 0.

What I claim is' p I 1. A machine for washing bottles provided with a receiving drum, a delivery-drum, means for imparting intermittent movement to said drums, and a pair of imperforate curved tanks beneath the drums, substantially as specified.

2. A machine for washing bottles provided with a receiving-drum, a conveyerat one side thereof, and a delivery-drum at the other side thereof, substantia1ly as specified.

3. A machine for washing bottles provided with a receiving-drum, a conveyer at one side thereof, a delivery-drum at the other side, and means for imparting alternate intermittent movement to the conveyor and the drums, substantially as specified.

4. A machine for washing bottles provided with a receiving-drum having pockets, a conveyer having a series of guideways in alinenient with said pockets, and means for feeding the bottles along said guideways, substantially as specified.

5. A machine for washing bottles provided with a receiving-drum, a delivery-drum, a series of rotatable rollers opposite the deliverydrum, and a brush above said rollers, substantially as specified.

6. A machine for washing bottles provided with a receiving-drum, a delivery-drum, a series of rotatable rollers opposite the delivery-drum, a brush above said rollers, and means for removing the bottles from said rollers, substantially as specified. I

v 7. A machine for washing bottles provided with a receiving-drum having pockets, a' conveyer having guideways in alinement with said pockets, a delivery-drum having pockets, rotatable rollers opposite said drum, a scrubbing-brush, and means for removing the bottles from the rollers, substantially as specified. v v
