The sleeve carries a gear ||`I which backs and the ear fronts so that the pockets of meshes withv a pinion HS on the shaft 2D. Thus the turret are provided with the ear backs, and it is that the chuck is rotated from the shaft 20. when the pocket has an ear back therein, an ear The chuck is moved endwise by a lever I I 9 which front will be fed on to the same. This assembles is pivotally mounted on the bracket I 25. Said the parts of the ear ready for the applying of lever carries a yoke end |2| provided with rollers the coating thereto. The turret is then turned to bring the assembled parts of the ear to the coating stations. One of the coating stations is indicated at C in and the other at C’. They are similar construction, and only one will be described in detail. The column I2 extending up through the central part of the machine is stationary and 15 carries the sleeve :il at the upper end thereof. 10 Said sleeve carries a projecting boss Q8 which sup engaging an annular groove |22 in a collar |23 carried by a member |24 that can slide vertically. The shaft §25 which carries the chuck H9 bears on the collar |23 so that when the collar is raised, 10 the chuck is raised, and when the collar is low ered, the chuck will be lowered. The lever H9 carries a roller |25 running in a groove in a disk Ii’ll fixed to the shaft l2. The flow of the sealing material through the 15 nozzle |55 is controlled by a needle valve |28. ports the bracket carrying the coating devices. This needle valve is held closed by means of a spring |29 and is opened by a control lever |30. This control lever |39 is pivoted at 3| to the bracket An adjustable stop bolt |32 limits 20 The bracket is indicated at tf. Said bracket is pivoted to the boss by a pivot pin IQG. The 20 bracket is shown in Fig. 9 in operative position, and it is held in this position by a bolt ISI pass ing through openings in the bracket arms and the downward movement of the lever, but is so positioned that the spring will close the valve. through a projecting bracket i'ë‘è carried by the The levers IN! controlling the two nozzles are sleeve. The bracket 99 is in the forni of a cross simultaneously operated for opening the valves 25 head H33 carrying two forwardly extending and downwardly inclining arms íûLl. Attached to each arm is a coating nozzle IGS. A supply pipe tdt leads from the nozzle to a mounting in the arm |134 and a flexible pipe iGl is attached there 30 to for supplying coating to the nozzle. is, of course, a supply pipe te? for cach coa - `ozzlc, and these supply pipes extend to the sleeve Si at the top of the column and are con~ 35 which nected extends to a feeddownwardly pipe shown in through dotted the linescolumn a i to the base of the machine. The base of the nia chine has a suitable supply pump for feeding the coating material to the nozzles. The nozzle 585 is so disposed that it is directly above the pocket in the ttu'ret when the turret comes to rest at the coating station. The table or plate IB is provided with an open ing IGS in which is located a chuck HE). The chuck I I0 has a recess in its upper face adapted 45 to conform to the shaping of the backing, and the turret moves the assembled ear par ts directly over the chuck, so that the ear back will fall into said recess. The chuck is rotating continuously and it is intermittently raised so- as to lift the assem 50 bled parts of the ear from the pocket into contact with a gravity held centering rod I H. 'This rod engages the ear front at the opening therein and through the following mechanism. A shaft |33 25 is mounted in bracket arms i333, 33a carried by the cross head Attached to the shaft is an arm |354 to which a spring |[email protected] is attached, and this spring normally tends to turn the shaft in a clockwise direction as viewed in Fig. 9. Also 30 attached to the shaft E33 is an arm |35, which carries a rod |35. Said rod is threaded into the arm for adjustment and is held in set positions by a lock nut i3?. when this rod |35 and the arm §35 are'raised then the shaft |33 is turned in a counterclockwise direction as seen in Fig. 10. The rod §35 bears on the upper end of a rod £35“ which is raised and lowered by mechanism which will be hereinafter described. Attached to the shaft |33 is a bracket E38 (see 40 Fig. 9). There is a similar bracket and associ ated parts for thercontrol lever operating the farther nozzle. As these parts are all similar it will only be necessary to describe in detail those shown in Fig. 9. Said bracket arm |33 is pro vided with a recess in which is located a control block |39. A spring |39a located between the control block and the bracket arm |38 normally forces the block to the limit of its movement to the right as viewed in Fig. 9. The block |39 rests on the bracket arm. Extending along each side of the control block |39 are bars |40, |40. will serve to center the ear front on the ear back A pin I 4| is fixed to the control block |39 and and also guide the assembled parts during the extends through slots MIE in the bars I 49, |48. 55 rotating of the parts through the rotating of the chuck. In other words, this centering rod is free to rotate and will hold the parts through the weight thereof, in contact with the chuck so that ` the chuck will rotate the parts. As shown m Fig. 60 9, the ear parts are raised to the dotted line po sition and rotated, and in this position the nozzle IE5 is directly ’above the channel in the ear back, and directly over the outwardly flaring flange of the ear front. The valve of the coating device is 65 opened, and a jet of coating material is forced from the nozzle on to the assembled ear parts. This will form a coating at the peripheral edge portions of the ear parts all the way around the ear. 70 The chuck is mounted for rotation in the upper frame and carries an elongated pinion | I2. This pinion meshes with a pinion H3 on a stub shaft H4, and the pinion H3 in turn meshes with a pinion H5 attached to the sleeve HS which is mounted for free rotation on the colunm 2 (see These bars are held mounted to rock in diiîerent positions and this is the means which limits the movement of the control bar £39 to the right as Viewed in Fig. 9. Pivotally attached to the con trol lever |3§l is an upwardly extending member |42. Said member extends into a recess in the control lever and is carried by a pivot pin |52“. Said member is provided with a shiftable plate |43 which is secured to the member |42 by suit able bolts which permit said plate to move end wise in said member.
