My invention relates to means for feedthe bar 28 on the machine-frame, t ing caps, especially, but not restrictedly, .of the screw, as Wlll be readily undew those having screw-threads, or similar arad ust1ng the position or elevation of th ticles, so that they may be ap lied to the cap chute. necks of containers, such as ottles, jars As is shown m Figure 5, the ski ingchute co d'th lik comprises a plate bent longitu inally to One aim of the invention is the provision provide a lower portion 41, a vertical abutof a structure of this character, which is ment wall 42 and an upper or cover art simple in construction, which can be pro- 43 d1sposed at an inclination to the ase I0 duced' economically and which will aceomsection 41, the latter having mounted there- 6| modate caps of diiferent sizes. on, as by screws or bolts 44, another bent Other advantages incident to the invenplate member, shaped to provide a base 45, tion will become apparent from a consideraan upright wall 46 of less height than the tion of the following detailed specification wall 42, and a sloping floor section 47 which of a desirable embodiment thereof which is extends down from the top mar of wallz 70 illustrated in the accompanying drawings, 46 to the junction of the parts 41 and 42. throughout the several views of which like Thus a longitudinal opening or slot is reference characters have been employed to formed betweenthe' lower edge of the vpart designate the same parts;- 43 andthe adjacent/portion of the floor 47. v In these dra in The up er part" of such chute, at one 76 Figure 1 is a ragmentary elevation of side, is tted with a laterally inclined, the construction; i small, auxiliariy or supplemental chute 48 Figure 2 is a fragmentary cross-section which may be ormed as a part of the plate on line 22 ofFigure 1; of which the" sections 45, 46 and 47 consti- 26 Figure 3 is a similar horizontal cross-sectute portions or it may be a separate mem- 80 tion on line 33 oiFigure 1; her supported ,in position in any approved Figure 4 is an enlarged partial plan view or convenient way. 7 r

This screw carries the weight of the chute it enters the open mouth of a cap as the 88 and associated parts and imposes it through latter comes along, it will arrest or stop the 110 igure 7 is a fragmentary longitudinal It will be perceived that each cap or cover 90 i passage of such cap and succeeding ones until the misplaced one is removed or properly replaced. a

This detent easily rides over properly positioned caps as indicated in Figure '5.

Near the lower end of the chute, a casting 61 is fixed against the under side thereof and it has an extension 62 square in cross-section, disposed at one side of and lengthwise the chute.

On this part 62 a stationary bent finger 63 is secured, its'end projecting into a circular or annular groove 64: (Figure 4) in a knurled screw 65 having complementary right and left-hand thread sections, an end of such screw having a readily accessible knurled lock-nut 66 for retaining the adj usted screw in position against unintentional turning The oppositely-threaded, spaced sections of the screw extend through correspondingly-threaded holes in ears 67, 67 of a pair of inverted T-shaped brackets 68, v69 slidingly mounted on the supporting-bar 62,

whereby turning of the screw 65 causes the.

two brackets to approach one another or recede from one another, as will be readily understood, and, in order that they may be retained or secured fixedly in adjusted relation, each is supplied with a thumb set-screw 71 designed to bear against the outer face of the bar 62 (see Figures 4 and 6).

. Bracket 69 has a flange 72 and bracket 68 i has a complementary flange 78 both designed comes along on to receive and support the caps 51 as they, during their descent in the chute, pass from the latter, on to the spaced, transverselydisposed flanges 7 2 and 73 and, in order that the capsmaynot fall down between such flanges. I provide a correspondingly-sloping plate 74 between them mounted atits upper end by screws 75 on the extension of the part 45 which projectsbeyond the ends of the plate sections 43, 42 and 47.

As is shownin Figure 4, a curved plate 7 7 is mounted by means of screws 78, 78 on the top of the bracket 68, such plate, in some cases: assisting the descending caps in making the right-angle turn.

The lower ends of the two brackets 68 and 69 are supplied with properly-shaped retaining companion springs 79, 79 which temporarily prev/enfi further descent of the caps untila-]ar,,bottle or like 81 (Figure 6) a conveyor not shown andby engagement therewith pulls the foremost cap out of such delivery chute in opposition to the slight" or lesser retaining action of thetwo springs.

To hold the most advanced cap down in proper position, on the end of a suitablysupported bar 82, adjustable as to position guideby its retaining screw and thumb-nut 83, I pivot or hinge a plate 84: at 85 and to press this downwardly on to the top of the cap I use a coiled spring 86 encircling a rod 87 .hinged at 88 to the top of the plate and slidable through an aperture in a guidebracket 89 the upper end of the rod having one or more limiting nuts 91 which restrict the descent of the plate, the latter being yieldingly held down to its work by the spring which bears at its opposite ends againsta collar on the rod and against the under face of the part 89.

From the above description and associated illustration, it will be seen that the cap introduced by hand into the entrance chute slides down the latter into the main chute and glides down this in contact with the wallfl2, occupying or extending out of the longitudinal opening along one side of the chute, so that the appliance is readily adapted to accommodate caps of differentsizes.

The caps pass in succession on to the flanges 72 and 7 3 and the intermediate plate 7 4, turn the corner and slide down into contact with the retaining springs 7 9 from which they are abstracted by the passing jam or bottles with which they automatilimits without departure from the heart and essence of the invention and without the sacrifice of any of its substantial benefits and advantages.

1 claim: In a construction of the character describedfa chute having a longitudinal guide;-

wall, a supporting 'wall inclined to feed bodies thereon lengthwise the chute and also inclined toward said guide-Wall to maintain the bodies in contact with the latter during such travel, a second chute at the lower end of said first chute disposed at an angle thereto anddesigned to receive the bodies therefrom, saidsecond chute being composed of two companion parts, means to adjust said parts toward and from oneanother to adapt the chute to accommodate bodies of different sizes, and a guide-plate on and adjustable with one of said parts to assist the bodies in turning from one chute to the other. v

In witness whereof I have hereunto set my hand and seal. I
