Original application filed June 6, 1905, Serial No. 263,978. Divided and this application filed December 29,

1905. Serial No. 293,858.

To all whom it may concern:

Beit known that I, XVILLIAM DAYTON a citizen of the United States, and a resident of Bridgeton, Cumberland county, Improvements in Glass-Blowing Machines, of which the following is a specification.

My present invention, which is a division of an application for patent filed by 'me June 6, 1905, Serial No. 263,978, relates to machines for blowinghollow glass-ware, and consists of certain improvements in that class of apparatus designed to effect automatically, by the aid of fluid under pressure, air for instance, the intermittent rotation of a carrier supporting the blow-molds; means for automatically arresting the movement of such carrier gradually, means for effecting the automatic rotation of a press-mold carrier; the movement of such carriers bearing a definite relation to each other so that when they stop one set of the molds supported means for auto- 'matically raising the press-molds into the blow-molds at regular intervals to receive a charge of glass which is subsequently recessed by a plunger, such action forming the neck and shoulder of the article of hollowmeans for withdrawing the pressmold; means for effecting the partial movement of the carrier supporting'the blow:

molds to a position for blowing thecharge of glass within said molds, and means for effecting the further movement of the carrier supporting the blow-molds for the purpose of removing the finished article.

Other features of the invention and the details of construction will be fully pointed out hereinafter, reference being had to the accompanying drawings, inwhichz Figure 1, is a frontelevation, partly in section on the line a-0.', Fig. 2, of sufficient of a glassblowing machine to illustrate the subject of my present lan viewi showing the blow-mold carrier;

ig. 3, is a sectional plan view, taken on the line b-b,1Fig. 1, showing the press-mold the means for operating the same and the fixed table below the'blow-mold carrier; Fig. 4:, is a rearelevation of the mechanism for rotating the blow-mold carrier,

a detached view,

trolling the fluid pressure passing to the New Jersey, have invented certain I the movement invention; Fig. 2, is a I piston for efiectingthe movement of the blow-mold carrier and the mechanism for operating said valve; Figs. 6 and 7 are de tached views illustrating details of my invention, andFi 8, is a vertical sectional view of apart 0t my invention.

The improved machine forming the subject of my invention, together with its operative mechanism is mounted upon av carriage 1' having a fixed table 2. T his table has a central stemv 3 providing a journalfor the rotatable blow-moldcarrier 4:. In addition, the table '2 carries means for effecting the rotation of the blowmold carrier means for stopping and locking the same after each quarter revolution; a rotating carrier 5 supporting a series of press-molds 6; and a cylinder 7 having a piston 8 which is employed to move said press-molds nto and out of a series of blow-molds 9, (only one of which is shown), a

mounted on the carrier 5. The blow-molds are provided with bottoms movable by suitable means out of and into their operative position with relation to said molds by and during the rotation of the blowmold carrier, all-of which is described in my application before referred to.

The press-molds 6 are carrier 4, and the carrier 5 so press-molds has a gear whee disposed below the porting said 10 meshing ,with another gear wheel 11 of the same diameter, keyed to and rotating with the hub 12 of the carrier' l so that for every quarter-turn of this latter carrier, a fresh press-mold will be in osition to be raised into a fresh blow-mold to receive a charge of lass; its movable bottom being automatlcally withdrawn to permit the insertion of the press rnoldas said blow-mold is moved to the chargin position. At the lower end of the centra stem 3, a ball-bearing' may be provided so that friction due to of the carrier 4 will be as little as possible. i p

Beneath the table '2, the cylinder 7 is mounted, having a rod 14 and piston 8, which rod, when pressure is applied to the under side ofits iston, serves to ash one of the press mol s into one of t e blowmolds disposed above and in registrythere I drawn after the the blank or press-mold, the glass meanwhile being suspended in the neck of the blow-mold. The press-molds are provided with dependin'- headed stems 15, and the upper end of tie rod 14 has a'slotted head 16 with inwardly projecting'jaws 17 to engage the heads of said stems. mo

throu h the pipes 18 and 19 which are connecte' by a three-way valve 20 and receive their pressure from a pipe 21. The valve may be operated by a handle 22.

As soon as the press-mold 6 has been withformation of the blank, the carrier 4 is ready to be moved a quarter turn, during which time the blow-mold bottom is pushed into place, and this movement of the carrier is effected by the following mechanism machine,

- (not shown) the Carried by the table 2 at the rear of the is a cylinder 23 in which apiston 24 carried by a rod 25 reciprocates, the opposite end of which rod is provided with a smaller piston 26 arranged to enter an openended cup or auxiliary cylinder 27 forming a dash pot, and which, when said piston 1s entering, serves to retard the movement of the blow-mold carrier as it nears the end of its quarter turn. The rod 25 carries a pivot connection 28 for the end of a crank arm 29, which is journaled in a groove '30 formed in the hub 12 of the carrier 4, and this arm, in combination with a pin 31 supported by a spring 32 and adapted to enter an aperture therein, is employed to move said carrier. In Fig. 3, the crank arm is shown in position to engage the carrier and move the same a quarter turn, while in Fig. 4, the pin is shown in engagement with the carrier at the end of quarter turn.. The carrier has -a series of apertures 33 for engagement by the pin 31, so that when the arm is moved in the arc of a circle by its connection with the rod 25, the carrier will be moved with it, the arm being slotted at 34 for proper engagement with said pivot connection.

. The pin 31 is held in engagement with thecarrier by the spring 32, and after said cal'rier has been moved .a quarter turn, (the extent of movement of the crank arm 29,) it is-,. to*be"'looked or held against further movementiluring the yarious steps incident *to the formation of the hollow glass-wareunder 'process of manufacturey For this purpose, saidcarrierjis provided with another series of apertures 33, and .pin 31 is arranged to be projected into one of said holes, of which there are four, when the carrier 4 reaches the end of its quarter turn. Leading to each of these apertures is an inclined surface'on the under side of the carrier so that said pin may start to engage the carrier-before the latter comes to the limit of its movement, and this pin is maintained in engagement with the carrier by means of a spring 32}: clearly shown in the sectional view, F 1g. '8. \Vhen it is desired to impart further movementto the carrier, the pin 31 is withdrawn therefrom by means of a lever 34. This mechanism is fully described in my application for patentabove referred to and as it forms no part of my present invention it need not be further described.

Pressure to operate the piston 24 is delivered by the pipe 35, and is controlled by a four-way valve 36 havin an arm 37 by which it may be operated. link 38 is connected at one end tothis arm and at its 0pposite end to a coiled spring 39 anchored at 40. A lever 41 pivoted at 42 is also con nected to the link '38, and this lever has an upwardly projecting end 43 lying in the path of the head 17 of the piston rod 15. In Fig. 1, the piston rod is in the lowered position, and the valve 36 has been moved by the mechanism notedabove to a position to permit pressure to enter the cylinder through the pipe 44, moving the piston 24 in the direction of the arrow at, F 1g. 2; thereby moving the carrier a quarter-turn. When the piston rod 14 is next raised to lift a pressmold into one of the blow-molds to receive a charge of glass, the lever 41 will be released, permitting the spring 39 to shift the 7 fore" the carrier can be a head 51 valve 36, through the medium of the link 38 and arm 37, to the position shown in the diagram view, Fig. 5, and pressure from. the pipe 35 will enter the pipe 45 leading to the cylinder 23 to retract the piston, the valve meanwhile permitting pressure to-ex-- haust through the pipe 44 and the commonexhaust outlet 46. Upon lowering the piston rod 14 to withdraw a ress-mold, the valve 36 will be again shifte by the engagement of the head 16 with theend 43 of the lever 41, and pressure entering the cylinder through the pipe 44, the carrier will be moved another quarter-turn, and so on. Begiven further movement, however, it is necessary to disengage the driving means and retract the same for a 'fresh engagement. The pin 31 is withdrawn 1 by means of a rod 47 connected to a piston- 48, supported by a spring 49 and disposed in a cylinder 50- mounted beneath 'the fixed table 2. The lower end of the pin 31 has withjiws 52 to engage thehead ...52e-.o;fii'fhe rod 47. and .pressurebein'g admitted to act upon the'pistori 48, said rod be withdrawn and with it said pin; thereby releasing the crank .arm from, its connec- 'tion with the carrier. Immediately following this action, pressure isadmitted to the cylinder 23 through the pipe 45;, and this pressure moving the piston 24: and rod 25, the crank arm 29 will be retracted until its pin 31 is directly beneath another opening 33 in the carrierinto which it will enter under the influence of the spring 32. The mechanism is now ready to move the/carrier another quarter turn, and this action may i the head 53 of the rod 4:7 for lowering the same.

It is desirable that the carrier 4; be brought to a stop with ,asiittle jar as possible In or- ,der that the articles of hollow-Ware in procmeans ess of manufacture and disposed within the blow-molds, shall not be displaced and caused to engage one side or the other of the molds, a condition which would cause a faulty finished article. For this purpose, the pipes 44 and 45 leading to the cylinder 20 are provided with check-valves 55 and 56,

and the auxiliary cylinder-27 is provided with a check valve 57, each of said valves havingmeans to permit bleeding of the pressure so that they gradually exhaust at one end or the otheras the pressure is entering the opposite end.- This device operates as a brake to check the movement of the carrier as it approaches its position of rest, permit ting a movementthat is fast enough but one in which the stoppage is so gradual that no harm may come to the article being blown. The cylinder 7 is also provided with check-valves 58 and 59 connected to its combined pressure delivering and exhaust pipes 18 and 19 respectively. These check valves are placed at points to intercept back pressure or exhaust during certain parts of the operation of the \machine. They are fully described in my application above referred to, and specifically application for patent filed by me June 6, 1905, Serial No. 263,977.
