Referring particularly to the drawings, the apparatus' comprises a feed belt A which is adapted to convey jars B in an inverted position against a stop C. The jars are pushed laterally from the conveyor A by means of a cross slide D to a jar 60' guide. E. A feed bar F reciprocable parallel with the jar guide E engages the positioned jars and moves them laterally successively into position directly above brushes G. The feed bar F is reciprocable vertically up'wardly at the right hand end of its horizontal stroke to a position free of the jars and is reciprocable vertically downwardly at the left hand end of its Vertical stroke into position to engage additional jars to be cleaned. The feed bar F is. provided withV a plurality of fingers a, b, c, d, e, g and see Fig. 2, for engaging and positively positioning the jars.` rlhe feed bar F can be moved longitudinally a distance equal to twice the distance between adjoining pockets.

When the feed bar F has reached the right hand end of its horizontal stroke, the jars over the brushes G are engaged by suitable cross slides- I-I which securely clamp; the jars and maintain them in fixed position while the feed bar is moving vertical-ly upwardly, then horizontally to the left as viewed in Fig. 12 and vertically downwardly. The brushes B move upwardly into the interior of the clamped jars when the feed bar F moves upwardly, see Fig. 12, and move down-v wardly from the clamped jars when the feed bar F moves downwardly. i

Successive horizontal movement of the feed bar F to the right brings the brushed jars into position over nozzles I which inject airv into the brushed jars, see Fig. 13. The thus cleaned jars B are delivered on to an endless conveyor J, see Fig. 15, by which they are delivered to a suitable place of disposalrnot shown. Fig. 13 shows the brushes G and the nozzles I in their lowermost position prior to being moved upwardly into jars and with the feed bar F in its lower position.

Fg. 14 shows the feed bar F in its elevated position and the brushes G and the' norzzles I projected into the interior of the jars.

Fig. 15 shows the 'position of the jars in the next succeeding stroke of the feed bar F in` the right hand direction. The feed bar F has made one additional stro'ke to the right, as viewed in Fig. 13, as compared with the showing of Fig. 12, thereby bringing the' first jar into position over the first nozzle I.

The feed conveyor A for feeding jars into the machine comprises a belt Aone end of which is supported and driven by a pulley wheel 2, see Figs. 1, 5 and 7, mounted on a shaft 3 which is supported in suitable bearngs in a main frame 5 of the machine. Power to drive thebelt conveyor is supplied from a main drive shaft 8 which is driven by a central source of power, see Figs. l, 3, 7 and 8, namely motor 9 through a belt iii, speed reducer i l, chain E2, sprocket wheel id and clutch |5.

Power is transmitted from the main drive shaft 8 to a cam-shaft 25 through a sprocket wheel 2|; chain 22 to a sprocket wheel '23 keyed to' the camshaft 20. The cam-shaft 20 drives the feed belt pulley 2 by means of a bevel gear 25, see Fig. 4, keyed to the cam-shaft 20, bevel gear 26, sprocket wheel 21, chain 28 and sprocket wheel 29 keyed to the shaft 3.

The inverted jars B having been carried by the conveyor until the endmost jar abuts the stop C, the first and third jars are translated laterally from position No. 1 to position No. 2 by means of cross slide D. The second jar is held by a removable stop S which is removed when larger jars are used. The cross slide D comprises a slide plate having spaced arms 35 and 36 adapted to engage the first and third jars. The slide plate is mounted for reciprocating movement transversely of the conveyor A and is actuated by means of a cam 38 driven by the cam-shaft 20. The cam 38 has a cam-way 39 engaged by a cam follower 40 which in turn drives a lever 4| to rotate a post 42 rotatably carried by the main frame 5. The post 42 actuates a lever 43 which through the link 44 reciprocates the cross slide D from position No. 1 to position No. 2 and vice versa.

The post 42 is keyed to a link 50, see Figs. 1, 4 and '1, which in turn has pivotal connection with a link assembly 5|, which by pivoting about a pivot point 52a secured to the frame of the machine controls the spacer or Separator 5|a, for the jars. The bar 5| is returned to its original position and away from the post 42 by means of link 50 through rotation of the post 42 and the cam 38. The light spring 5|b functions to soften or lessen the shock of the spacer 5|a against the jars when the slide and spacer come together.

The two jars B having been moved to position No. 2 are supported upon suitable jar guides 60 which extend longitudinally of the main frame 5 of the machine. The jars B are now carried in step by step movement longitudinally of the machine upon the jar guides 60 by means of the feed bar F and its depending fingers a to h inclusive. The fingers a to h inclusive are cup shaped members which are adapted to freely receive and positively position the jars. The feed bar F is supported by a feed bar frame including slide bars 62 andl 63, see Fig. 5, which depend downwardly and which carry a bridge 64 beneath the jar guide 68, see Figs. 2, 6 and '1. The bridge 64 is composed of a main bar 64 and a parallel bar 640. The feed bar assembly moves up and down with feed bar F and is balanced by a weight 64' to insure smooth action. The weight 64' is supported by a lever 64a on one side of the pivotal connection 641) of the lever 64a to the frame 5. The lever 64a on the other side of pivot 64b is connected to the bridge 64. The slide bars 62 and 63 are mounted for vertical reciprocation in guideways 66 supported by the main frame 5 of the machine.

The feed bar assembly is driven in Vertical reciprocation through the following arrangement of parts: The slide bars 62 and 63 each carries a cam follower 10 which are adapted to be actuated by cams 1| driven by a feed bar cam,- shaft 12. The feed bar cam-shaft 12 carries rigidly a mitre gear 14 which meshes with a similar gear 15 on a shaft 16. The shaft 16 carries rigidly a mitre gear 11 which meshes with a similar gear 18 mounted upon the cam-shaft 20.

Horizontal reciprocation of the feed bar F is effected by the following arrangement of parts: The slide bars 62 and 63 of the feed bar frame carry bracket arms 81 at their upper ends which in turn support guideways 88 in which the feed bar F has horizontal reciprocatory movement parallel with the jar guide 60. This movement is effected through a link 90 which is pivotally attached at one end to the feed bar F and at its other end to a lever 9|, see Figs. 1, 2 and 20, the base of which is pivoted at 92 to the frame 5 of the machine. A link 93 is pivotally connected to an intermediate portion of the lever 9| at one end and is pivotally connected at its opposite end to a cam-lever 94. The cam-lever 94 is pivoted to the main frame 5 at 95. The camlever 94 carries a cam follower 96 which engages in the camway of a feed bar stroke cam 91 driven by the shaft 16. The lever 9| is normally maintained in its retracted position indicated in dotted lines in Fig. 20 by means of a helical spring 9|a.

The Vertical and longitudinal reciprocation of the feed bar F is so timed that when the feed bar F is at the left hand end of its stroke as viewed in Fig. 1, the feed bar is drawn vertically downwardly into position for the feed bar ngers a and b to engage jars B which have been positioned upon the jar guide 60. The feed bar F is then moved to the right as viewed in Fig. 11 while retained in its lower position thereby moving the jars forwardly. The feed bar is then lifted vertically upwardly to a position in spaced relation to the jars after which the feed bar is moved horizontally to the left as viewed in Fig. 12 to its initial position. The jars are thus moved forwardly in successive increments to position the jars successively directly above the brushes G.

When the feed bar F has arrived at the end of its stroke to the right as viewed in Figs. 1, 2 and 11 the jars are clamped between the cross slides H. The cross slides comprise plate members mounted for reciprocation transversely of the jar guide 60 in guideways |0I. The plate members |00 are recessed at |02 and are provided with fingers |03 to receive the jars. The plate members are reciprocated by the following arrangement of parts: A link has pivotal connection with the plate members and with a lever 106. The lever |06 is actuated by means of a post |01 rotatably mounted in the frame 5 of the machine. The post |01 carries at its bottom a cam lever |88 carrying a cam follower |09 which engages in the camway of a cam I|0 driven by the shaft 20. The post |01 has driving connection with the farther cross slide H by means of an arm |01a pivotally connected to a link |01c which in turn is pivotally connected to an arm 0117 rigidly secured to the post |01 which actuates this particular cross slide H.

The brushes G are elevated upon the upward stroke of the feed bar F into the interiors of the clamped jars and are retained in their elevated position while the feed bar F passes in horizontal travel to the left as viewed in Fig. 1. The brushes G are driven in rotation through the following arrangement of parts: The brushes G which are situated on bridge 64 carry gears ||5 which mesh with a gear ||6. The gear ||6 is mounted upon a shaft ||1 which carries a bevel gear ||8. The bevel gear ||8 meshes with a bevel gear ||9 on a shaft |20. The shaft |20 carries a sprocket wheel |2| which is driven through a chain |22 and sprooket wheel |25 from the cam-shaft 20.

The revolving brushes loosen and remove any particles of dirt upon the interior of the clamped jars while the feed bar F is making its return stroke. The cross slides H then separate releasing the jars whereupon both the feed barF and the brushes G are lowered.

The jars are now moved horizontally to the right as Viewed in Fig. 1 to a position directly over the nozzles I, situated on bridge 64. Upward movement of the frame carrying the nozzles I injects the nozzles into the interior of the jars whereby the inner surfaces of the jars are cleaned by a blast of fluid such as air or the like. Any loosened material remaining after the brushing operation is blown from the jars. The supply of air to the nozzles I is Controlled by an air valve contained in an air line |3| which opens into an air Chamber |32 mounted upon the bridge 64, see Figs. 4 and 5. The nozzles I project directly from the air Chamber |32. The clean jars are delivered from' the jar guide 60 to a conveyor J which conducts the clean jars to a suitable place of disposal, not shown.
