MACHINE FOB LIQUID-PBOOFING VESSEIIS.

Specification 0'! letters Patent.

To all whom it may concern: I

Be it known that I, Ham 0. AYERBT, a citizen of the United States, residin at Seattle, in the county of King and, tate of Washington, have invented certain new and useful Improvements in Machines for Liquid-Proofing Vessels, of which the following is a specification.

This invention relates to machines or apparatus which are utilized to render liquid roof vessels, bottles or other receptacles ormed of a perforate or absorbent material. Its object is to produce an efiicient and ra idly operating machine of this character. he invention consists in detices whereby a water-proofing substance, such as paraifin,

is supplied to a receptacle for coating the internal surfaces thereof, means for removing any surplus of such substance from the receptacle and means for a tomatically regulatmg the movements 0 the receptacles during and subsequent to their being made water-proof.

The invention further consists in the novel construction and combination of parts, as.

will be hereinafter described and claimed.

In the accompanyin drawings, Figure 1 is a longitudinal vertical section of a machine embodying the present invention. 2 is a view of the same, partly in plan section the section being taken through 2-2 of 8 is a horizontal sectional view through 3---3 of Fig. 1. Fig. 4 is a detail sectional view .through 4-4 of Fig.2.

The machin herewith illustrated is designed, more particularly, for applying a water-proofing substance to the interior of bottles, although it may be similarly used for other receptacles, such as pails or cuspidors. I q

Referring to the drawings, the; numeral 5 designates the top or table of the machine frame, and 6 is a conveyer belt whereby the articles to be treated are brought to one end of said table. Included in said frame is an uprightpost 7 having secured to its upper end a non-rotatable cylindrical bowl 8 provided in its periphery with a port 9,-Fi 3. Superposed upon said bowl is cover'w ich may be constituted by the flange 10 of a pipe wlhereby molten paraflin is supplied to e w Fi' 1. Fig.

.14 of the spout a 1 or formed on the u Rotatable upon the post is the tubular stem 13 of a casin 14'which is bored to receive said bowl. nthe peri heral wall of the casingl 14 is a plurality o spaced openings for t e receptlonof dischar e spouts 15.

16 represents a gland for hol inga packing ring 17 to prevent any leakage at the upper edge of said casin At its lower end the stem 13 is rovi ed with a spurgear wheel 18 which Is engaged by a toothed pinion 19 mounted upon a shaft 20. This shaft is driven by means of a chain 21 and sprocket wheels 22 from 'a power-driven shaft 23.

At a distance above the table 5,the stem 13 is provided with a disk-like flange 24 of a radlus suflicient to extend over the-conveyer-belt 6. This disk or carrier, as it will be hereinafter designated, is provided in its circumference with a series of recesses 25 which are disposed beneath the respective spouts 15.

6 represents a guide ositioned above the belt 6 for directingt e bottles conveyed thereupon into positions to be engaged within the carrier recesses 25, as they are successively presented in therotating of the carrier in the direction indicated by arrow A in Fig. 2. The bottles are thereupon revolubly moved. from the belt and upon the table by the carrier. I

On or about the time a bottle is thus carried onto the table the oplening in the casing hove t is bottle traverses the bowl port 9 resulting in a quantity of parafiin discharging through thespout into the bottle.

In the further rotation of the carrier, the bottle is withdrawn from the table, then inverted to allow the paraflin to flow over the throat and mouth of the bottle, pour out the surplus, and finally deposit the inverted bottle upon a rack or conveyer.

The mechanism by which these actions are accomplished will nowbe described.

26 represents abox'which is secured'to ppe'r end of an upright Patented Jan. 1', 191s.

shaft 27 which is ournaled ina block 28 secured to the machine-frame. Extending to said arm and tending to push the jaw to the extent of its movement toward the box 26. Within the referred to arm socket the stalk 29 is provided at diametrically opposite sides with

grooves

29 and 29 to successively receive a spring-pressed ball 32 which serves to yieldingly hold the jaw 30 in normally horizontal positions.

Opposing this jaw is a second jaw 33 having a stalk or rod 34 which extends axially through a cylindrical chamber 26 provided in the box 26 and to a distance therebeyond.

Near its extremity remote from the jaw 30 the rod 34 carries an arm 35 upon which are rotatably mounted

rollers

36 and 37 arranged to respectively track against the outer edge 38 and the under-side 38 of a bar flange 38 which constitutes a cam. This cam is provided with a central curved portion concentric to the axis of the shaft 27 which serves as a swivel for the box 26 while the

end portions

39 and 39 of the bar are directed outwardly, as shown in Fig. 2.

40 represents a helical spring acting between an end of said box chamber and a collar 41 provided on the rod 34 whereby the latter is caused to push the jaw 33 -toward the other jaw, subject to the influence of the cam. Y

Splined to the rod 34 is a toothed gearwheel 42 which engages an arcuate rack 43 provided on the block 28 and serves to efl'ect the turning of the rod and the jaw 33 when the box 26 is turned on its swivel. The gear- Wheel 42 is, however, secured against axial movement by means of a stud 44 extending into an annular groove provided on the wheel hub 42.

The shaft 23 is provided with a crankarm 45 which is operatively connected by a rod 46 with a crank-arm 47 provided on the shaft '27. The crank-arms are proportioned so thateach revolution of the arm 45 will reciprocate the other arm through an are somewhat less than 180 to afford corresponding movements to the box 26 and the parts carried thereby.

48 represents a receptacle into which the surplus para. 11 is poured from the bottles and 49 is a rack whereupon the bottles are deposited in inverted positions.

The operation ofthe invention is as follows:

The paraflinin a liquid form is supplied to the bowl 8. The bottles, as B, are fed nto the recesses 25 of the carrier 24 as they are revolubly moved over the belt 6. In being conveyed bythe carrier and when, with a bottle in about the B position, the respective spout 15 passes the port 9v in the bowlj8, a charge of paraffin will be delivered through such spout into a bottle. When a bottle is" carrie into the position indicated by B, Fig. 2, the jaw 33 will be at adistance from the bottle, of devices other jaw 30 suflicient for the bottle to enter the Immediately after this occurs, the crankarm 45 is being revolved by its shaft 23 to impart motion, through rod 46 and the crank-arm 47, to the shaft 27 so as to rotate the box 26 on the axis of the last-named shaft so that the rod 34 will be swung in the direction denoted by arrow C.

In this movement the spring 26 asserts its power to cause the roller 36 to track against the opposing edge of the cam flange so that when the roller has reached the concentric portion 38 thereof, the jaw 33 is thrust against the bottle and pushes the same against the other jaw 30 in opposition to the spring 31;

Meanwhile, the box 26 is turning and cooperates with'its arm 26 to carry the bottle in the direction indicated by arrow E. During such action the gear wheel 42 is affected by the rack 43 to give rotary motion to the jaw 33 and also, through the medium of thebottle, aflords like motion to the jaw 30.

At the end of its travel, the jaws have been turned over to invert the bottle and thereby empty the surplus parafiin into receptacle 48. During the last part of the above described travel, the roller 36 encounters the portion 39 of the cam, resulting in the withdrawal of the jaw 33 and thereby deposits the bottle in an inverted position on the rack, as indicated by broken lines]; in Fig. 2. After this is attained, the crank-arm acting through the rod 46 and crank-arm 47 turns the box 26 and the parts which are carried thereby into the positionsin which they are represented in In tunning the jaw 30, the spring-pressed ball 32 is pushed by the rotating stalk 29 from one groove, as 29 Fig. 4, at the beginning of such rotary movement, and enters the other groove 29 at the termination thereof, thus arresting the stalk and its jaw after making a half-rotation, where it remains until restored to its original position in the inverting of the next bottle, and so on.

Having described my invention, what I claim, is

1. In a machine of the class described, the combination with a rotary bottle-carrier, and means for supplying a liquid-proofing space therebetween.

material to bottles in their orbital travel with the said carrier, of means for removing the bottles from said carrier, said bottleremovin means including devices whereby the bottlis are inverted subsequent to beingtaken from the carrier. i
