LIQUID GRAVITY FEED SYSTEM The invention Comprises a slide reciprocated between a reservoir for liquid and a conveyor for syringe barrels. Apair of nozzles are reciprocally supported by the slide to engage the syringe barrels equidistantly spaced on the conveyor and during the movement of the slide toward the conveyor. Said engagement of the nozzles with the syringe barrels will move the nozzles from the conveyor independently of the slide. Clamping members are carried by the nozzles and yieldingly urged toward anvils mounted on the slide and arranged to support intermediate portions of flexible conduits connected to outlets of the reservoir and to the nozzles. The yielding force of the clamping members will squeeze the intermediate portions of the conduits against the anvils and shut-off the flow of liquid to the nozzles. The engagement of the nozzles with the syringe barrels will move the clamping members from the flexible conduits and permit the flow of liquid to the nozzles and the filling of the syringe barrels. The rate of flow of liquid to the syringe barrels is regulated by levers adjustably mounted on the slide and extended over the portions of the flexible conduits supported by the anvils. Adjustment screws are carried by brackets adjustably supported by the slide. The adjustment screws are normally positioned by the brackets to contact the levers and position the levers on the flexible conduits to regulate the flow of liquid to the nozzles. The brackets are adjusted on the slide to position the adjustment screws out of contact with the levers to per mit replacement or sterilization of the flexible conduits.
In the drawings accompanying this application:
FIG. I is an elevational view of the system;
FIG. 2 is a front view of the slide. nozzles. clamping members, anvils. levers. adjustment screws and brackets;
FIG. 3 is a side view. on an enlarged scale, of the slide. a nozzle. clamping member, anvil and intermediate portion of a flexible conduit;
FIG. 4 is a front view looking at the right hand side of FIG. 3;
FIG. 5 is a side view, on an enlarged scale. of the slide, a lever. adjustment screw and bracket; and
FIG. 6 is a front view looking at the right hand side of FIG. 5.
The embodiment of the invention, as shown in FIG. 1, is supported on a table relative to a turret 8 secured on a shaft 9 rotatably supported by the table and intermittently rotated by suitable means, not shown. The turret 8 is arranged to be engaged by equidistantly spaced syringe barrels I0 supported by an annular platform 11 mounted on the table.
A slide I2 is reciprocally supported in a vertical standard 13 mounted on the table and said slide 12 is reciprocated toward and away from the table by a cam disc 14 rotatably supported by a base 15 of the table and continuously rotated by a suitable source of power. not shown. Rotation of the cam disc 14 is transformed into reciprocation of the slide 12 by an arm 16 pivotally supported at one end by the table and having a follower I7 intermediate its ends and maintained in engagement with the cam disc 14 by a spring I8. The opposite end of the arm 16 is pivotally connected to the slide 12 by a rod 19.
A pair of nozzles 20 are carried by rods 2] slidingly supported in brackets 22 mounted on the slide 12 in vertical alignment of the path of travel of the syringe barrels I0 on the platform I I. The nozzles 20 are yieldingly urged toward the syringe barrels II) by springs 23 retained in recesses 24 in the upper ends ofthe rods 2] by plugs 25 suspended from a bracket 26 projecting from the front of the slide I2, as shown in FIGS. 2, 3 and 4. The slide 12 is actuated toward the syringe barrels I0 during the period of rest of the turret 8 and said actuation of the slide I2 will engage the nozzles 20 with adjacent syringe barrels l0 and move the rods 2! against the force of the springs 23.
A liquid reservoir 27 is supported above the bracket 26 by a post 28 mounted on the standard 13, as shown in FIG. I. The reservoir 27 is provided with outlets 29 connected to one end of flexible conduits, such as hoses 30, and the opposite ends of the hoses 30 are connected to the nozzles 20, as at 3I. Intermediate portions of the hoses 30 are supported by anvils 32 mounted on the slide I2 to cooperate with clamping members 33 carried by the nozzle rods 21 whereby said intermediate portions of the hoses 30 are squeezed against the anvils 32 by the clamping members 33 under the influence of the springs 23 and the flow of liquid is shut-off from the nozzles 20 with the slide I2 positioned from the syringe barrels I0. When the slide 12 is actuated toward the syringe barrels l0 and the rods 21 are moved against the springs 23 by the engagement of the nozzles 20 with said syringe barrels 10, the clamping members 33 are lifted from the hoses 30 to permit a flow of liquid to the nozzles 20 and the filling of the syringe barrels 10 positioned below said nozzles 20.
Downward movement of the rods 2] is limited by the hoses 30 and when the hoses 30 are removed to be sterilized, downward movement of the rods 2I is limited by the clamping members 33 abutting the anvils 32.
The rate of flow of liquid to the nozzles 20 is regu lated by levers 34 pivotally mounted on bolts 35 supported by the slide 12 and said levers 34 are retained in adjusted position by screws 36 threaded in the bolts 35. The levers 34 are laterally extended from the bolts 35 over the portions of the hoses 30 on the anvils 32 and said levers 34 are adjusted toward and away from the anvils 32 to vary the degree of compression of the hoses 30 by the levers 34 and the rate of flow of liquid to the nozzles 20. This adjustment of the levers 34 is aceomplished by screws 37 adjustably mounted on brackets 38 adjustably mounted on the slide 12 by screws 39 threaded in the slide 12 and provided with manipulating members 40.
To remove the hoses 30 for renewal or sterilization, the screws 39 are loosened to permit swinging of the brackets 38 to position the screws 37 out of contact with the levers 34.
The number of nozzles and their component parts may vary according to the manner of conveying the syringe barrels I0.
Having thus described my invention, I claim:
I. In a liquid gravity feed system. a liquid reservoir having an outlet, a nozzle reciprocally supported below the reservoir. a flexible conduit connecting the reservoir outlet to the nozzle, an anvil reciprocally mounted between the reservoir and the nozzle and supporting an intermediate portion of the flexible conduit, and a clamping member carried by the nozzle above the anvil and yieldingly urged to squeeze the conduit against the anvil and close said conduit, whereby reciprocal movement of the nozzle toward the reservoir will move the vary the space between the lever and the anvil by the adjustment of the screw.
3. A liquid gravity feed system as claimed in claim 2. wherein the bracket is adjustably mounted on the slide to have adjustment toward and away from the lever and position the screw out of contact with the lever to permit the removal of the conduit.
