FRUIT-JAR OR BOTTLE MACHINE.

SPECIFIGATIGN forming part of Letters Patent No. 701,188, dated May 27, 1902.

Application filed October 24, 1900. Serial No. 34,170. (No model.)

To all whom, it may concern.-

Be it known that we, WILLIAM PHILANDER' FISHER and HARLEYPULASKI LUDINGTON, citizens of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented a new and useful Fruit-Jar or Bottle Machine, of which the following is a specification.

Our invention relates to glass-blowing machines, and more particularly to ya machine for forming fruit-jars and bottles, &c., and has for its object to produce a machine of this kind in which the melted glass can be easily placedand quickly formed into the desired object; audit consists in the improved construction and novel arrangement of parts of the same, as will be hereinafter more fully set forth.

In the accompanying drawings, in which the same reference-numerals indicate corresponding parts in each ofthe views in which they occur, Figure 1 is a side elevation, partly in section, of a machine embodying our invention. Fig. 2 is a top plan view of the same; and Figs. 3 and 4 are front views of the mold, showing it in two positions.

Our machine is preferably supported by a column 1, that has its lower end fianged and bolted or otherwise secured to abase-plate 2. The intermediate portion of the column is provided with a collar 3, upon which is supported, preferably by ball-bearings 4, the lower end of a hub 5 of a flat horizontallyarranged plate 6. A circular way 7 is secured to the hub of the plate in any suitable manner, as by brackets S. The lower edge of the way, which is arranged concentric with the column 1, is provided with a series of notches 9, by means of which the way and the plate or table 6 may be rotated by means of a pawl 10 in a reciprocatory head 11, that is secured to the outer end of the piston 12 of an air-cylinder 13. The cylinder is pivotally mounted upon a bracket 14 on the base, so that the head may follow the movement of the circular way as it is moved back and forth by the piston, and the head is pivotally secured to the piston, as by means of a pin 15. The pawl 10 is arranged to reciprocate within the head and has its lower end reduced and passed through a bracket 16. A

spring 17 encircles the lower end of the pawl and engages with the bracket and theshoulder of the pawl at the end of the reduced portion to normally force the upper end of the pawl into engagement with the notched surface of the way. The length of the stroke of the piston is regulated bya set-screw 18 at the outer end of the cylinder, and the cylinder is provided with a three-way valve 19, which is provided with two inlet-ports and one exhaust-port for the purpose of reducing the pressure upon one end of the cylinder. The cylinder is preferably reinforced on the side where the ports lead from the valve to the ends of the cylinder.

' Mounted upon the upper surface of the table 6, which is preferably made angular, five sides or angles being shown in the drawings, are suitable glass-blowing apparatus, one for each side of the table, one only being shown in the drawings, as said mechanisms are all alike. A shaft-.20 is journaled in suitable bearings'21 on top of the table, and a disk 22 is secured to the outer end of the shaft, so as to overhang that edge of'the table. A twopart mold 23 is hinged to the disk, as shown at 24:, so that it may be opened for the removal of the article after it has been blown. The part-sof the mold are held together in any suitable manner, as by means of arms 25, which project from the forward portion thereof in position tobe grasped by the operator. One end of each part of the mold is provided with a pin 26, which fits in a groove 2'7 in the under sideof a plate 28 and causes the mold when closedto stand centrally relatively to a plunger 29, said plate being secured to a bracket'30, that projects from the disk 22.

The bottom 31 of the mold is removable and is held in position relatively to a lever or handle 32 by means of pins 33. .A stem 34 from the bottom passes up through the lever and is provided at its upper end with a notch 35, in which a cam 36 on the side of a rotary post 37 is moved for the purpose of raising and lowering the bottom of the mold. The post 37is rotated in its bearings by means of a handle 38, and the face of the bottom 31, which engages with the ends of the molds, is preferably recessed or shouldered, as shown at 39, to engage with a corresponding shoulder on'the molds to assist in holding the molds together and making a tight joint at the end of the mold. The lever 32 is pivotally secured to the disk, so as to be swung to one side When the bottom has been raised from the mold for the insertion of the glass from which the article is to be formed. A setscrew 40 is located in position, as in a bracket 41, to limit the return movement of the lever and cause it to be stopped with the bottom directlyabove the bottom of the mold, so that when the handle 38 is rotated the bottom 31 will be forced into proper engagement with the bottom of the mold.

The bracket is preferably secured to the disk, substantially midway of its ends, with the mold 23 upon one side and the plunger 29 upon the other, the plunger being journaled in a 'bearing 42 and provided with a head 43 at its inner end and a pinion 44 near its outer end. The plunger is hollow and terminates at its inner end in the head 43, which is of the same. diameter as the internal diameter of the neck of the article being formed. The plunger is provided with a hollow valve-stem 45, which is provided with a mouthpiece 46 for thercception of the blowpipe, which may be of any ordinary construction and is not shown. The inner end of the stem is provided with a conical head 47, which is adapted to fit against the head 43 of the plunger, and is perforated at the inner end of the head, as shown at 48, whereby the perforations are closed when the heads are in contact, but are opened when the head of the valve-stem is forced inward away from the head of the plunger.

A spring 49 surrounds the valve-stem and engages at its outer end with a nut or collar 50, which is adjustably secured upon the stem for the purpose of holding the head at the inner end of the stem against the head of the plunger. The pinion 44 is secured to the 'outer end of the plunger, so as to'permit of a slightlongitudinal movement of the plunger through the pinion, as by making the plunger angular in cross-section.

Two brackets 51 and 52 are adjustably secured to the edge of the table 6 in position to support two segments 53 and 54 at right angles to the plane of the table. One of the segments 53 has its outer face provided or formed into'a rack 55, which is adapted to engage with and rotate the pinion 44 as the disk 22 is rotated by means of the shaft 20. The other segment 54 is provided with a slot or groove 56, which extends from end to end and has one end arranged'at a greater distance from the center of the disk or the axis has a trunnion in position to enter the groove 56 and is preferably provided with an antifriction-roller 59. When constructed in this manner, the rotation of the shaft 20 will invert the disk 22, which will cause the pinion 44 to travel around the rack 55, which will rotate the plunger in its bearings. It will also cause the trunnion of the collar 57 to pass around the cam-shaped groove 56, which will cause the plunger to be moved lengthwise into the mold as it is rotated, thereby causing the glass, which has been dropped into the top of the mold when the mold-was inverted, to be crowded into the neck of the mold and give it the proper shape, and especially where the neck is to be provided with screw-threads, as in fruit-jars. After the mold has been turned in its upright position by'this movement of the parts the mouthpiece is connected with the blowing mechanism, whereby the glass will be blown out against the sides of the mold as it gradually settles to the bottom, thus forming a complete article, which can be subsequently removed from the molds when they are separated.

Rigidly secured upon theshaft 20 between the bearings 21 is a pinion 60, which is adapted to engage with and be rotated by a vertically-movable rack 61, which is mounted in a bracket 62 upon the table 6. The rear face of the rack is preferably provided with a dovetailed rib 63, which fits in a corresponding groove in the front of the bracket. The upper end of the rack is provided with a laterally-extending arm 64, which is adapted to fit within a cam-shaped groove 65, formed in the periphery of a circular track 66. If desired, the arm may be provided with antifriction-bearings 67. The track is secured to the column 1, near its upper end, by means of a spider 68. The track is provided with two inclined or cam-shaped portions, one of which, 69, is shown in Fig, l, for the purpose of moving the rack twice for everyrotation of the column, and the length of each of said cammed surfaces is just sufficient to cause the shaft 20 to be rotated one-half ofa revolution for each reciprocation or longitudinal movement of the rack, and the parts are so arranged relatively to each other that each reciprocation or rotation of the shaft will be completed when the table has been brought to a standstill after two of its movements. The shaft'20 may be removably held in its bearings by means of a collar 70, which is socured upon its inner end in any suitable manner to engage with the inner bearing 21, the hub of the disk engaging with the outer bearing and preventing longitudinal movement of the'shaft.

In operating our improved glass-blowing machine the table is rotated until one of the disks stands with the bottom ofthe mold upward. The bottom of the mold is then swung to one side and the charge of glass is inserted and permitted to fall down upon the conical end of the headof the plunger in the neck of the mold. The piston ofthe air-cylinder is then forced outward, which will cause the table to be given a partial rotation by'means IIO is still hot. blown the mouthpiece is disconnected from this rotation of the table the disk is inverted and the plunger forced into the neck of the mold by a rotary or spiral movement, which will force the glass into the neck of the mold. By the time the table reaches the limit of its movement the disk has been inverted and the mold placed with its neck uppermost, which will cause the glass to gradually settle to the bottom of the mold. The mouthpiece of the plunger is connected with the source of air, and the valves or lateral openings in the head of the plunger are opened by forcing the valve-stem inward, which will permit the air to enter the mold and blow the glass while it As soon as the article has been the source of air and the valve-stem is drawn outward by the action of the spring around its outer portion. As soon as the glass has been blown the table is given another forward movement by the air-cylinder, which will cause the disk to be returned to its normal position with the bottom of the mold upward. The bottom is then removed from the mold, the molds are opened and the article removed, after which the table makes the de: sired number of movements, preferably two, to permit the molds to cool sufficiently before another charge of glass is inserted. By providing each edge or side of the table with a disk and means for rotating it five articles may be produced for each rotation of the table, as each set of blowing mechanisms will be operated in the same manner as soon as the arm on the vertical rack of the table comes into.

engagement with the same portion of the cam, the cam being rigidly secured against rotation at the upper end of the column.

As the parts of the machine as above described can be arranged very compactly, the machine will occupy but little space, and the parts are so simple and can be constructed in such a substantial manner that they will not be liable to be broken or disarranged. It is evident that jars or bottles may be rapidly produced with the help of but few attendants, who need not necessarily be skilled in the art of glass-blowing, and the articles thusproduced will be of a superior quality owing to the manner in which the plunger is inserted into the neck and the article is blown as theglass is settling to the bottom of the mold.
