To all whom t may concern: g

Be it known that we, ALBERT S. REEVES, of Bridgeton, and FREDRIOK J. MAURADER, of Millville, in the county of Cumberland, State of New Jersey, have invented certain new and useful Improvements in Bottle-Making Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improvementin bottle-molding machines, the object of the invention being to provide simple and etlicient means for molding bottles and to so construct the devices by means of which air is forced into the glass that the molten glass -will be effectually prevented from entering the pipe or tubular rod through which the air passes.

A further object is to provide devices for opening and closing the neck portion of the mold and to so construct said devices that they can be readily adjusted, whereby to insure the complete closing of said neck portion of the mold.

A further object is to so connect the operating-lever with the tubular rod which forms the opening in the neck of the bottle and conveys air to the molten Aglass for forming the body of the bottle that the free vertical movements of said tubular rod will be insured.

A further object is to so construct the machine that it will operatefreely and effect ually to perform its functions.

Vith these objects in View the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of our machine, partly in section. Fig. 2 is av horizontal cross-section showing the devices for operatin g the neckmold in plan. Fig. 3 is a view illustrating details.

A represents a table supported on legs a and provided on its top with a mold B. A standard l is disposedA at or near one end of the table A, or, more properly, projects upwardly from a base-plate 2, secured to said table. The standard l is provided at or near -its top with a forwardly-projecting arm 3,

having a socketin its under face, in which socket a pintle 5 at the upper end of a bracket 6 loosely enters, the lower end of said bracket being provided with a pintle 7,- mounted in a suitable socket in the base-plate 2, said bracket being thus mounted to swing, for a purpose which will be hereinafter explained.

The bracket 6 is made with an outwardlyprojecting arm 8, provided at its free end with two cross-heads 9 9, the lower crosshead 9 being made longer than the upper one and provided with holes for the accommodation of two rods c c, which latter are also guided in their movements in recesses in the ends of the cross-head 9. The lower ends of the rods c carry a follower-plate d, and between said rods a tubular rod or pipe l0 is disposed and adapted to pass freely through of nuts d, which serve to prevent said crosshead e from moving upwardly on said rods. Collars f are also secured to the rods c c'v some distance below their screw-threaded portions, and between said collars and the ends of the cross-head e springs g are located on said rods c c. Thus it will be seen that the rods which carry the follower-plate are yieldingly connected with the tubular rod or pipe lO, so that when the latter is moved vertically the follower-plate is moved also.

A post or standard h is secured to the arm 8 of bracket 6 and projects upwardly therefrom. The post or standard h is madev with a series of perforations h', whereby a lever ll can be adjustably pivoted thereto. The lever l1 is preferably made angular in form and provided at one end with a weight h2 and at the other end with a handle h3. Between the handle h3 and the pivotal support of the lever 11 the latter is widened, as at z', and this widened portion is made with an opening i', through which the tubular rod or pipe l0 freely passes. The pipe or rod 10 is provided at or near its upper end with a col- IOO lar from which arms 7U' 7; depend, the lower ends of said arms being pivotally connected to a rod 7d, passing through the opening '21' of lever ll. From this construction it will be seen that when the lever ll is operated the tubular rod or pipe l() will be moved vertically without danger ol' binding in its guides.

A laterally-projecting pipe l5 communicates with the tubular rod l0 and is adapted to receive a tlexible or other pipe connected with an air-compressor, said pipe l5 being provided with a valve lt.

The portion 19 of the mold (by means olf which the neck of the bottle is termed) is made in two parts 2O 2l, hinged together, and the pintle et said hinge serves to pivotally connect said part itl to the top of the main portion ll of the mold. The respective parts of the part lt) of the mold are recessed eentrally to form an opening for the admission of the lower end ol' the tubular rod 10, the latter being limited in its downward movement by means of a collar thereon. The bracket 6 being pivotally supported as above explained it can be swung so as to move the parts carried thereby laterally in one direction, but will be prevented from moving` laterally in the other direct-ion by means of an arm or stop 23, secured at one end to said bracket and adapted at its other end to engage the standard l. Thus it will be seen that when the bracket is swung into operative position it will be prevented from moving farther than is necessary to cause the rod t3 to properly aline with the hole in the mold by means of the arm or stop i3. The partit) oi' the mold is provided with means whereby the same can be operated automatically when the bracket is swung laterally. To accomplish this, the devices now to be explained will be employed. An arm 25 is secured to and projects forwardly from the lower portion of the bracket o', said arm being provided with a series ot perforations in, whereby to adjustably attach thereto a forwardly and laterally projecting arm To the tree end of the arm 25 one end et. a link 2G is pivotally connected, the other end of said link being pivoted tothe part 2O ofthe mold. Another link 2T is pivoted at one end to the arm at a point rearwardly from its end, and the other end ot link 27 is pivoted to another link 2S, the other end of the latter being secured tothe part 2l of the mold. The links and 27 are each made in two parts, adjust-ably connected together by means ot' turnbuckles. From this construction and arrangement of parts it will be seen that when the bracket is swung in one direction parts O 2l will be moved outwardly in opposite directions and release the neck of the bottle. 'hen the bracket is moved in the other direction to bring the tubular rod lO to its operative position, the parts 2O 2l will be brought together, and by making the links 26 27 adjustable the close titting ot the parts E20 2l can be insured.

and on the underside ot said table a movable plate or block 2t) is located and made with an opening 30, adapted to aline with the opening in the mold, said plate or block being supported by guides 31, and to said plate or block an arm or handle .'52 is secured by means of which to operate it. The arm 32 is provided with a depending arln (made in two parts, pivoted together,) to the lower end of which a lever 3l is pivoted at a point between its ends.

rlo the Ainner end et the lever fl-t a plungerrod 35 is pivoted, and said plunger-rod is provided at its upper end with a plunger 3U, adapted to operate in the hole in the plate or block 20. ln order to insure the tree movement of the plunger 3G and prevent the same from any liability to bind, a cross-head n is secured between its ends to the plunger-rod 35 and provided with holes near its ends, through which holes guide-rods o, secured to the block 20, freely pass. The free end et' the lever lt is provided with a weight 37, adapted to counterbalance the inner end ot' thc lever and the plunger and plungerrod carried thereby.

ln operating the apparatus the plate or block 2) may be swung out ot' line with the mold .Il for the insertion ot glass into it, after which said plate or block will, be moved in line with the mold l?, and. the tree end of the lever St will then be depressed to cause the plunger 3G to ascend and force glass into the portion lt) of the mold, whereby to form the neck.

Instead of moving the plunger upwardly by manipulating the lever l-l, a :toot-lever q may be employed, one end ot said toot-lever being connected by a rod fr with the plungerrod or with the inner end ot' the weighted lever S-t.

lYhen the glass shall have been forced upwardly within the mold ll, as above explained, the tree end of the lever ll will be lowered to cause the tul'lular red or pipe lt) to enter the mold and form the opening in the molten glass tor the neck of the bottle. lhe followerplate will also be lowered when the lever 1l is depressed, whereby to form the mouth of the bottle, the under face of said followerplate being made with a recess into which the glass will enter for this purpose. Then the tubular rod or pipe l0 shall have entered the mold and passed through the neck portion thereof, the valve 1G will be opened and compressed air permitted to escape through the pipe 10 and form or blow the glass within the mold B to form the body portion of the bottle. The lever ll will then be raised to remove the tubular rod and follower-plate. A lateral movement of the lever ll will now cause the bracket t5 to swing laterally and open the portion lt) of the mold, as above explained.

It has been found that should the lower end of the tubular rod or pipe l0 be unguarded the molten glass will be apt to enter the same and clog it when said rod or pipe Ais projected into ICO IIO

19, disposed a short distance below the outlet of said tubular rod or pipe, said guard serving to prevent the entrance of glass into the tubular rod or pipe without preventing the proper escape of compressed air through the latter. In constructing the guard p we prefer to make the same spherical, so that the compressed air will be discharged laterally and downwardly from the end of pipe or tubular rod l0 and operate effectual] y to formtheglass into a bottle. The spherical guard p is supported in a fixed position a short distance below the outlet of pipe or tubular rod 10 by means of a rod s, passing upwardly through the latter and secured at its'upper end to a cap t, adapted to screw on the upper end of pipe or tubular rod lO. In this manner the guard will be held in a normally-fixed position, but can be removed for repair, if necessary, by removing the cap t.

Our improvements are simple in construction, easy to manipulate, and are effectual in all respects in the performance of their functions.

Slight changes might be made in the details of construction of our invention without departing from the spirit thereof or limiting its scope, and hence we do not wish to limit ourselves to the precise details herein set forth.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is

l. In a bottle-making machine, .the combination with a mold and a swinging bracket, said mold having a sectional neck portion, of an arm projecting from the swinging bracket, a bar adju stably secured to said arm, a longitudinally-adjustable link pivoted at its respective ends to said bar and one section of the neck portion of the mold, a longitudinallyadjustable link pivoted to the bar inwardly from its end, and a link pivoted at one end to the last-mentioned link and at the other end rigidly secured to the other section of the neck portion of the mold, substantially as set forth.
