Specification of Letters Patent.

Patented Apr. 6, 1915..

Application filed April 4, 1912, Serial No. 688,499. Renewed May 7, 1914. Serial N 0. 837,082.

To all whom it may concern Be it known that'we, JOSEPH MERRITI and CHARLES H. STORES, citizens of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Machines for Feeding Rings, of which the following is a specification.

. This invention relates to a machine which is particularly designed for feeding light,

in a uniform manner. This object may be attained by providing a hopper having inclined walls with an opening at the bottom, below which opening is the tip of a collecting rod. The rings are put into the hopper, and sliding down the side walls drop out of the opening. Some drop onto and are caught by the collecting rod, down which they pass. Others escape and drop into a rotary elevator which carries them up and pours them back into the hopper. If the rings are split,and the machine shown is designed to feed split rings, as the rings pass down the collector rod they are manipulated so as to be turned and fed with all the openings in line with each other. This is accomplishedby providing the collecting rod with a feather. If the rings pass down in such position that the feather enters between the opened ends, the rings continue to drop. If the rings do not reach the feather in the proper position they are turned around by suitably rotated wipers until the openings between the ends are in line with the feather So that the rings will drop down. This locates the rings on the rod one above the other with the openings in line in such position that they may be uniformly fed to other mechanisms for subsequent treatment.

Figure 1 of the accompanying drawings shows a front, elevation of a machine which embodies the invention, with a portion of the casing of the rotary elevator broken away in order to Show the ring carrying buckets. Fig. 2 shows a side elevation of the machine with the hopper and rotary elevator out in central vertical section. Fig. 3 shows a plan of the operating mechanism, the hopper and rotary elevator being omitted. Fig. lshows on larger scale a plan of a wiper in the actof engaging a ring onthe collector rod so that the ring will be turned in order that the guiding feather may enter the opening between the separated ends of the ring. Fig. 5 shows a side elevation of the parts shown in Fig. 4. Fig. 6 shows a plan of the parts shown in Fig. 4 afterthe wiper has turned the ring so that the opening between its ends coincides with the plane of the feather. Fig. 7 is a side View of the parts in the position shown in Fig. 6. Fig.

8 is a sectional'view. of the'wiper rotating mechanism, on the planeindicated by the dotted line 8- 8 on Fig. 3. f

The mechanism illustrated as embodying this invention is mounted on a table 1 which is clamped upon the end of a supporting post 2. The hopper 3 is mounted on four posts which are supported by arms 5 projecting from the upper ends of the standards 6. The hopper has inclined bottom Walls,

and at the lower end is an opening 7. The rings which are placed in this hopper in a promiscuous mass work by gravity down the inclined walls and drop through the opening at the'bottom, thesize of which may be regulated by adjusting the movable gateplate 8.

Surrounding the hopper is a cylindrical elevator 9. This elevator has buckets 10 in i the interior, which, when the elevator is rotated, carry the rings up and drop them into the hopper. On the periphery of the elevator are two annular flanges 11 and an vent sidewise displacement of the elevator.

When the elevator is thus located, its peripheral rack 12 meshes with a pinion 16 on one of the shafts 13. The inwardly extending flanges 17 close the sides of the elevator buckets. Doors 18 are hinged to the bottom of the hopper for closing part of the opening in the sides of the elevator. On one side a button 19 is arranged on the underside of the elevator for the purpose of temporarily holding the door open when it is desired to inspect the interior. Plates 20 attached to the brackets 21 on the posts 4: are employed to close other portions of the opening in the sides of the elevator so as to prevent the rings from spilling out.

The collector rod 22 is located so that its tip is just below the discharge opening through the bottom of the hopper in position to catch rings which drop through the opening. Such rings as the collector rod catches slide downward. The rings which are not caught drop into the elevator and are carried up and returned to the hopper. The collector rod has a feather 23 which is clamped to the bracket 24L by the plate 25. At the upper end of the feather is a finger 26, and held between the bracket and theclamp plate is a small guide-plate 27. If the rings follow down the collector rod with the openings in line with the feather, as shown in Fig. 6, they will continue their movement down the rod. If the openings between the ends of the rings are not in line with the feather, as shown in Fig. l, they are caught with the finger 26 projecting through them, as shown in Fig. 5. They occupy this position until they are turned around the rod by the wipers or brushes into such position that the openings do coincide with the feather.

The brushes shown consist of wipers 28 clamped in a rotatable head 29 mounted on a vertical arbor 30. This arbor is fixed on the end of a swinging arm 31 which is pivoted on a post 32 that is fixed to the frame. (Fig. 8.) A spring 33 (Figs. 1, 3) tends to draw the arm bearing the wiper head toward the collector rod. This movement is limited by the stop screw 34 (Figs. 1, 3). Tn case the rings jam or get caught 011 the collector rod, the spring yields and allows the head to move away so that the rings are not crushed, or any of the parts injured. 0n the lower end of the hub of'the wiper head 29 is a pinion 85, engaging with which is a pinion 86 that is pivoted on a stud 37 also mounted on the arm. Engaging with the intermediate pinion 36 is a gear 38.0n the hub of the beveled gear 39 which is mounted on the post 82 which forms the axis of the swinging arm that carries the head. (Fig. 8.)

Meshing with the beveled gear 89 is a beveled gear 40 on a shaft 41 that is supported by bearings at the top of the brackets 42. (Figs. 2, 3.) On the end of the shaft 41, opposite the beveled gear 40 is a spur gear 43, meshing with which is a spur gear a l on one of the elevator supporting and rotating shafts 13. Connected with the gear 44 is a beveled gear 4L5, meshing with which is a beveled pinion 46 that is connected with the driving pulley &7. (Figs. 2, 8.)

The rings are thrown promiscuously into the hopper and flow down the inclined walls to the opening at the bottom. Some of the rings in dropping through the opening are in such position that they are caught by the collecting rod, others drop into the hopper.

When the mechanism is in operation, the hopper is rotated and the buckets carry the rings which drop into them up and pour them back into the hopper. This action takes place in such a way that the rings are caught by the collector rod very rapidly. Such rings as pass down the collector rod with the openings between the ends in the proper position continue their downward movement past the feather and are guided by the feather in proper position for future manipulation. Such rings as pass down the collector rod with the openings between their ends out of line with the feather are de tained until the revolving wiper turns them so that the openings will come into line with the feather and they can continue down the rod. The wipers shown are arranged on an incline so that they slightly lift the rings and tip the ends down in such manner that they are inclined to when turned engage with the feather and pass down. The finger at the upper end of the feather, which passes into the rings, holds them in a limit ner which facilitates this, as does the guideplate that is clamped to the bracket opposite the finger at the top of the feather. If the rings catch and tend to jam, the wiper head swings away, thus eliminating any danger of damage. When the jam is released, the wiper head is drawn back by its spring so as to continue its turning action on the rings. This simple mechanism automatically handles small, light rings as well as larger rings very rapidly and delivers them all in the same relation, that is, with the openings between the ends in alinement.
