Be it known that I, CHARLES E. Venn.. n citizen of the United States, residing at Erie, in the county of Erie and State oi' Pennsylvania, have inrentefi new useful Improvements in Glass-Blowing .V l chimes, of which the following tion.

This invention relates to machines and eonsiste in eertv A ments in the construction the reef :is ne hereinafter fully described and pointer' ont. in the claims.

One of the objects of the inrenten 'f provide n means whereby the effective in the cylinder being blown may be antw mutically varied to snit the requirements. This is preferably done by Varying the volume of air supply through the bien' pipe. It is also preferable to inem the nir rapidly with the initial moroni .i or of eration of the pipe, and While it is riesirzine to Continue the increase during the later stages of the operationa it is desiraiie to make the increase less rapid during those stages.

Another object of the invention is to vide a cover for the chamber carrying the pot for the molten glass, which will be :into maticnily lifted to permit the por; to lie turned with each operation.

Further objeeti of the invention reime to details of constrin tion and will animar more fully from the description and claims` The invention is iilustrated in the nonninpanying drawings as foliowsr-- Figure l shows lan View of the mnehine.

upright li?. The upper end of the bar is slidingly mounted by means of the stud h on the nut h5, the stud h* extending through the slot k3 in the bar. The nut h5 is mounted on the screw H1 and the screw H7 is journaled in the bracket lis and upright h". The upright hg is telescopically mounted in the upright It? and may be fixed in adjustment by the set screw 11.1. Hand wheels l1. are provided for operating the screws. A stop li is preferably;v arranged on the variation bar which limits the downward movement of the lever H so that some initial air may be had if desirediand it may be adjusted and lxedin adjustment by means of the set screw h1".

In the operation of the device the sliding connection i with the parts arranged as shown ,in Fig. 8 is much nearer the valve E2 in its initial position than in its upper position. As a result of this the efl'ective arm of the lever H is much shorter in the initial movement than in the later stages, so that with a given movement of the strap H there is a more rapid opening of the valve with the initial movement of the strap l-I than during the later stages. Thisvariation may be adjusted as desired by varying the angle of the bar H5, in fact the variation may be reversed.. I prefer however to have the initial movement more rapid as shown.

The shut off or controlling valve Ea as I provided is common.

On the end of thel air pipe C a spring v connection chamber F is secured. The sliding plug is arranged in this chamber and is presse outwardly by a spring F A passage f extends through the plu The blow pipe G has the lugs g arrange at the upper end thereof and an elbow g extending therefrom. A connectin socket g2 is placed in the upper face of this elbow. The hooks F2 are secured` to the chamber F and extend downward in proper position to engage the lugs g. The lugs are placed in these hooks with the pipe in position as shown in Fig. 7 As the tube is dropped it brings the socketI g2 against the end of the plug f so that a connection with the air is made. The usual waste or, vent g3 is arranged in the blow pipe.

The pot I is of the usual form and mounted in the chamber I3. It has the lugs z' which fit in the thiinbles i of the truiinions tending from the guides B. Cranks Is are fixed on the pins i2 and links I1 connect 'thesecranks with the slides I5. A handle Is is fixed on one of the pins 2 by means of which the position of the pot may be reversed. As it is swung over in either direction, the cranks operating through the links I donot wish to be limited to automatically varying the air actually supplied throug the blow pipe but wish to include devices wherein the e'ective air supply is. automatically varied. l

Y In the operation of the machine the molten glass is placed in the pot I. The

blow tube is brought into proper relationv with the glass in the ordinary manner. The tube is then drawn upwardly through the action of the motor through the gear D and rack c2. Just prior to the starting movement air is turned on by means of the valve E3. Theair is automatically varied by the valve E2 and its operating mechanism as the cage with the blow ipe is lifted so as to give the proper supp y of air to the cylinder in its different stages. After the cylinder is of suiicent length it is taken with the blow pipe from the machine. .The mechanism shown in Fig. 7 facilitates the removal of the blow pipe.

What I claim as new is 1. In a glass lrpwing machine, the coinbination of the ow pipe; means for supplying air thereto; a valve controlling the effective air supply; a lever operating said valve; a variation bar arranged at an angle to said operating lever; a connection slid.

supplying air thereto; a valve controlling.

the effective air supply; a lever operating said valve; a variation bar arranged at an angle to said operating lever; a connection slidingly mounted on said operating lever and variatiiliar; means operatin said connection as 'the pipe is operate and means for adjusting the variation bar.

3. In a glass blowing machine, the combination of the blow pipe; means for su plying air thereto; a valve controlling t e effective air supply; a lever operating said valve; a variation bar arranged at an angle.

to said operating lever; a connection slidin' liy mounted on said operating lever andvvaria-A tion bar; means operating said connection lot as the pipe is operated; and screws for adjusting the angle of the variation bar.

In a glass blowing machine, the combination wlth the blow pipe; of means for suppl'ing air thereto; a valve controlling the e ective air supply; the operating lever H arranged to operate said valve; the variation bar H5 having the slot ha therein; the sliding connection lz. slidingly mounted on the lever H and bar H5; screws Ha and H7 for adjusting the angle of the variation bar; and means for adjusting the distance be tween said screws.

5. In a lass blowing machine, the combination with the blow pipe`; of means for supplying air therneto; a valve controlling the effective air supply; the operating lever H arranged to operate said valve; the variation bar H5 having the slot las therein; the sliding connection h slidingly mounted on the lever H and bar H5; screws H" and H7 for adjusting the angle of the variation bar; means for adjusting the distance between said screws; and the stop h for adjusting the initial opening of the valve.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
