When articles are sold in, packages, it is now "customary to pack 1n the containers *therefona definite number of the individual articles." 'Dilficulty is experienced inpacking precisely the s'ame number in dlflerent con'tainersifftheParticles are measured by weighing them By means of my improved" machine, however, the number of crown caps or like articles to be inserted in thepackage 7 can be" counted with accuracy and the carton or container'therefor can be quickly and-easi ly filled invariably with the correct number of thearticles by unskilled and inexperienced wh n.

it F ig. 1 is a side iew of my improved mechaway for 'clearness. Y

"In thepractical embodimentofmy inven 'tion, thecrown caps 10 arefed to a, hopper 11 of the usual type, which is operatively con nected to a'suitable agitator 12. The agita: tor serves to align and to feed the caps in a single rowand .in the proper positions to a chute-1-3, and may libeoperated in the usual fmanner, as by means of the belt 14 driven by "a suitable source of power, not shown, and rotating the pulley 15, mounted on the agitaf torshaft.

' The chute 13' is formed with the cap passage .16 and may consist of the rear plate 17, the spacers 18 and the'front plates 19", all suit "'janismand the support for the containerto ably secured together as by means of the screws 20. Below the lower end 21 of the chute is arranged a table 54 of a height convenient to the operator. The chute is made of sulficient length to align therein at least the number of crown caps required to be inserted inthe smallest carton 22. It will be 7 understood that the chute is substantially upright so that the caps may pass out therefrom by gravity when allowed to do so.

Stop means are provided to maintain thecaps in the chute until a minimum predetermined number has accumulated therein, and

to release an unvarying number of said caps ,toallow said caps to drop into a carton 22 at the will of the operator. Said stop means includesa stop finger 23adapted to engage a capnear the upper end of the chute and a stop hook 24 adapted to enter the cap passage 16 and to be interposed between the low ermost cap in the chute and the end of the chute, together with suitable mechanism for operating the finger and the stop. The stop 24 is formed with a hook end 25 sufficiently thinto pass between the front plates 19 of the chute and into engagement with the front surface of the rear plate 17. The bearing brackets 26 secured to the chute as by means of suitable screws 27 serve as supports for the rock shaft 28, on which the stop 24 is supported. The lever 29 is also secured to the rock shaft28 and is connected at one end with the link rod and at its other end to the connecting link 31, a tension spring 32 acting on the lever 29 to maintain'the stop 24 nor- [mally in operative position. The lower end of the link rod 30 is secured to the treadle 33, pivoted at 34, so thatfoot pressure on the treadle pulls the link rod 30 and the lever 29 downwardly against the action of the spring 32 and moves the hook 25 out of the chute, thereby releasing the row of caps and allowing them to drop out of the chute.

The upper end 35 of the upright connecting link 31 is secured to the crank 86, which is mountedon the shaft 37, rotatably supported in the bearings 38. On said shaft 37, is fixed the crank arm 39 terminating in the plunger 40 which is inserted into the bore 41 of the finger 23. A pin 42 on said plunger 40 operon the mechanism avoided. The crankarm 39 and the finger 23 secured thereto may be mounted on the shaft 37 to project in substantially the reverse direction to that in which the stop 24 projects from its shaft 28, so that when the treadle33 is operated to withdraw the stop 24 from the chute to release the row of caps the finger 23 is caused simultaneously to enter the chute and engage.

the cap .adjacent thereto. Similarly, when the treadle is released, and the hook end 25 of the stop24 enters the chute under the infiuence of the spring-32, and stops the discharge of the caps from the chute) the finger 23 is withdrawn and allows the caps tofall into contact with each other in a row, filling up and accumulating in the chute above the stop 24. If the chute is designed for a four dozen carton, the finger 23 and the stop 24 are spaced apart a distance equal to slightly more than the combined diameters of fortyeight caps. The forty-ninth cap in the row counting up from the bottom, free of the finger 23, the row being supported by the stop 24.

. On the operation of the treadle, the stop 24 being withdrawn, the finger 23 engages the forty-ninth cap in the row and prevents that cap together with the caps thereabove from passing through the chute andinto the versed, whereby the row of caps accumulate above the stop'24 ready for delivery into the next carton.

It will be understood that, if desired, the crank arm 39 and the stop 24 may be mounted on'the same or corresponding sides of their respective shafts'and thatthe relative reversal in operation may be efiected by securing the lower end of the connecting link 31 to the left end of the lever 29 as viewed in Fig. 1 in a manner which will'be obvious. If the cartons are to be filled with larger numbers of caps, such as eight or twelve dozen, a multiplicity of identical chutes and connecting mechanisms may be provided. In Fig. 2, I have illustratedtwo additional chutes 46 and 47 arranged at an angle so that their respective lower extremities49 and 50 are spaced apart a'distance less than the size of the carton adapted to hold a gross of caps. The shafts 28 on the aligned chutes 49 and 50 may be removably coupled together by means of any suitable shaft coupling and an additional removable rod link 30 connected from the treadle 33 to the lever 29 is normally I of either of the chutes 49 and 50. The operator, to fill the largest size carton, need then only press the treadle which, with the connection ust described, operates all the chutes in unison. To fill the carton with eight dozen caps, the link rod 30 to one of the chutes need merely be disconnected, and the treadle operativelyconnected to only two of the shafts 28 as above described, whereby operation of the treadle releases the four dozen caps in each of the two chutes simultaneously. i

It will be understood that where a multiplicity of chutes 'is'used, the chutes may be advantageously emptied 1n succession, when ,filling even the smaller, size carton, since timeis thereby allowed'for the emptied chute to be again filled before'its turn comes to be falling within the spirit and scope of my in? V 1 vention and within the range of equivalents afforded by the appended claims. 1
