JONATHAN HALEY, OF AKRON, OHIO, ASSIGNOR TO THE AKRON GLASS & MACHINERY COMPANY, OF AKRON, OHIO, A CORPORATION OF OHIO.

JAR OR BOTTLE PRESS.

SPECIFICATION forming part of Letters Patent No. 711,962, dated October 28, 1902.

Application filed November 20, 1901. Serial No. 83,014. (No model.)

To tu whom it' ntfty concern,.-

Beitknown that LJONATHAN HALEY, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Jar or Bottle Presses, of which the following is a specification.

My invention has relation to improvements in presses for formingjars, bottles, and analogous articles from molten glass,in which the article is first formed into a blank in a mold by a reciprocating plunger and is then transferred to a separable mold, by which its exterior is shaped and expanded therein by means of a suitable fluid.

The objects of my invention are to produce a new and improved machine of the general class referred towhich shall be simple in construction, rapid and effective in operation, and one in which the operative 'parts shallbe reduced to a minimum consistent with' perfect work, and to provide simple and effective devices for opening and closing the blow and finishing mold, and to provide means for regulating the movement of the different parts to avoid shock andjar to the machinery.

To attain these aforesaid objects, my invention consists in the peculiar and novel construction, arrangement, and combination of parts hereinafter describedand then specifically pointed out in the claims, reference being had to the accompanying drawings, which form a part of this specification.

In the accompanying drawings, in which similar reference-n umerals indicate like parts in the different Views, Figure 1 is an elevation of my improved machine; Fig. 2, a side elevation of the lower portion of the same lookingl from the left of Fig. 1, with certain portions in section; Fig.- 3, an enlarged plan of the table, with parts above it in section in the plane of its top; Fig. 4,a section,enlarged, through the axis of a pair of molds, with certain parts in section; Fig. 5, a plan, enlarged, of the separable neck-mold and associated parts; Fig. 6, an inverted plan of Fig. 5; Fig. 7, a plan, enlarged, of the plate that su pports the blow-mold, showing the curved grooves that form ways for pins depending from opposite halves of said mold to cause said halves to separate; and Fig. S, an enlarged detailed view of the spring-bolt for regulating the throw of the air-applyinglever.

Referring to the figures, 1 is a table supported on side pieces 2, that rest on axles 3, on the ends of which are mounted wheels 4 for facility of moving the machine about.

In the top of the table 1 are shallow grooves 5, extending transversely across its entire upper face, constituting ways for slidable mold-bearing plates, to beA described. On each side of the ways 5 arise from the tabletop 1 parallel rods 6, constituting guides for the Vertically-reciprocating mechanism to be hereinafter described. These guides are united and` braced at the top by a yoke 7, having vertical internally-smooth openings centrally between the guide-rods 6, in which openings freely slide screw-threaded shafts S, each hearing at its lower end a cross-head 10. On the lower sides of these cross-heads 10 are plungers 9, and above the cross-heads 1.0 are somewhat-similar cross-heads 11. The lower cross-heads 10 are secured upon the ends of the shafts 8 by screw-threads, and the upper cross-heads l1 are supported by nuts 12 and 13, each bearing on either face ,of the cross-heads and are capable of being raised and lowered on the shafts 8 by rotation. Both of these cross-heads lO'and llhave extended side arms which t and slide on adjacent pairs of the rods 6.

Surrounding each shaft S is a ring 14, retained above and below by nuts 15 and 16, meshing into the threads onv the shaft, and depending from these rings 14 are sliding rods 17, having heads that prevent their descent therethrough and whichl are secured at their lower ends in a rim mold-plate 18, constantly pressed downward both by their weight and by coiled springs 19, surrounding the rods 17.

Secured at the bottom of the side pieces 2 and extending therebetween-is a lower platform 20, on which centrally beneath each shaft S is a cylinder 21, in which is a sliding piston, (not shown,) to which is connected a piston-rod 22, constituting a verticallyfreciprocating engine, each cylinder being provided with a valve-chest 23 and an ordinary D- Valve operating therein by means of a valverod 24.

IOO

Compressed air, which is generally the Inotive power used, is introduced into the valvechests 23 from any convenient source through the inlet and escapes in the usual manner. There are also exhaust-ports 26, closed by safety-valves 27 on the stems 28, provided l 24 and close the valve inthe valve-chest and prevent the further entrance of air when the pressure overcomes the resistance of and raises the safety-valve 27.

The piston-rods 22 are each secured to a cross-head 32 below the table 1, from the opposite ends of which extend vertically connecting-rods 33, passing up through the table and which are secured in the upper crosshead 1l. By this arrangement the cl'oss-head l1 and its connected parts are reciprocated vertically on the guide-rods 6.

In the bottom of the shallow grooves 5 in the table lis a slot 34, and in each of the grooves is a sliding plate 35, bearing a blankmold 36 and a blow-mold 37. The blankmold 36 consists of a metallicvcup-shaped vessel in which the molten glass is placed and pressed into the blank by descent of the plunger 9. This mold is externally reduced at the top to receive and fit the neck-mold, which is supported in a frame 38, slidablebetween guide-rods 6, and is sustained by rods 39, freely slidable in the cross-head 10, and these rods 39 have heads on their upper ends to prevent their descent therethrough and are arranged to'raiseithe neck-mold frame as the cross-head rises.

The neck-mold and its accompanying mechanism (shown enlarged in top and inverted plan in Figs. 5 and 6) embodies a frame 38, having a large central opening and having transversely across its upper facea dovetailed way in which slide two plates having their inner adjacent ends cut away in a circular shape. 'lhe two halves 40 of the neck-mold are fastened to the inner cut-away ends of these plates and are arranged to slide to meet and separate therewith, and in the lower face of the main frame 38 is a recess with ends cut in the arc of a circle concentric with the central opening of the neck-mold, inwhich is fitted a revoluble plate 4l, having a hole larger in size than said neck-mold. In opposite ends of the plates bearing the neck-mold are slanting slots 42, in which are arranged to slide bolts 43, depending from the under faces of said plates bearing the neck-mold. The-plate 4l has a handle 44, by which it may be partially rotated, by using which the halves of the neck-mold may be caused to approach and separate, as desired. The halves 40 of the neck-mold have such inner configuration as it is desired to give to theoutside of the neck of the nished glass article-as, for instance, a screw for a jar- 'ilhe blow-mold consists of Vtwo halves 45, hinged together to form the body portion, and the bottom 46 has a central depending peg that rests in a hole in tlie center of the plate 47. The plate 47 has two curved slots concentric with the hinge of the mold on opposite sides of the center and is itself supported above the sliding plate 35 by four integral corner-blocks (indicated by dotted lines in Fig. 7) that rest on the sliding plate 35, and these parts-namely, the plate 47 and the plate 35-are held together by corner-bolts 48. The inner faces of these corner-blocks are curved to form a circular recess in which is a revoluble plate 49, having slots, the ends of which nearest the center being in vertical alinement with the inner ends of t-he slots in the plate 47, but the outer ends of which diverge therefrom, as indicated in dotted lines in Fig. 7. In the bottom of each half of theblow-mold is a depending pin 50, that enters the slots in the

plates

47 and 49 when they are in vertical alinement. Extending from one edge of the plate 49 is a short arm 5l, adapted to alternately engage fixed blocks 52 66 as the plate 35 is pushed in one direction or the other, thereby turning the plate 49, and as a result the pins will follow the coinciding parts of the slots in the plates 47 49 to open and close the halves 45 of the blowmold as the plate 35 is pushed in one direction or the other, causing a partial revolution of the circular plate 49, and thereby causing the halves, as before stated, of the blow-mold to open and close, following the movements of the sliding plate 35.

Risingfrom the top 1 adjacent to the guides 6 and the transverse grooves 5, are a number of revoluble shafts 54, sliding on which are blow-arms 53. These arms are arranged to swing over the top ofthe neck-mold when it is at rest on top ofthe blow-mold and to fit closely thereon and have through them longitudinal ducts connected at one end by flexible tubes with a convenient source of compressed air and have at their free ends downwardly-opening spring closed valves 56, arranged to lie IIO centrally above the article in the blow-molds and in vertical alinement beneath the plungers 9. To cause these blowing-arms to assume their position and to recede therefrom when the jar or bottle is complete, there are secured to the lower ends of the shafts 54, beneath the table '1, crank-arms 57, wide at their free ends, in each of which there is a curved slot. (See Figs. 3'and 4.) From the bottoms of the sliding plates 35, centrally-depending beneath the blow-molds, are pins 58, that run in the slots in the crank-arms 57 and in the slots 34. Hence as the plates 35 are pushed in either direction to bring the blow-molds under the plunger-s 9 one end of the slots in the cranks 57 will encounter the pins 58 and rock the mold when in proper position over the blowmold.

In order to cause each blow-mold to assume its proper vertical position on its supportingshaft 54, the following mechanism is employed: Projectingfrom the side of the frame 38, carrying the neck-mold, is an ear 68, perforated near its end to inclose the shaft 54, and as the blowing-arm is placed on the shaft 54, above this ear 68, it will be raised by each upward movement of the neck-mold frame 38. It may be found necessary in practice to interpose between the ear 68 and the blowingarm on the shaft 54, as shown in Fig. 4, a collar to insure the proper elevation of the blowing-arm in order to swing over the top of the neck-mold frame. To cause ,these several operations to be performed, there is journaled opposite each valve-chest 23 a rockshaft 59, provided atits ends with levers 60 61, that extend to the front and back of the table l in convenient reach of the operator in their location. Secured to each of the rock-shafts l 59 is a short arm 62, forked at its front end l operated to actuate the piston and its rod to reciprocate the cross-heads and plunger. To guard against the stroke of the cross-heads being given with too great an impulse and to act as a half-way stop, there is placed on the under front edge of the table 1 (on the left in Fig. 2) a stirrup 64, in which the lever 60 is permitted a limited vertical movement. This stirrup 64 has projecting from one end of its inward side faces a notch to prevent the lever boing moved to its full throw without an additional movement of the operator, and

this stirrup is also provided at the bottom of shaft S.

the slot therein with an adjusting-screw 69 to limit the downward movement of thelever 60. As a further guard for the same purpose as just stated there projects from the back of each of the rock-shafts 59 a rigid arm 65 (see Figs. 2 and S) in alinement with the lever 61, in which is a transverse spring-pressed bolt 67 with a rounded end arranged to engage a depression in the lever 6l. This bolt is, so arranged that its point will rest on the side surface of the lever 6l, when it is at the eX- treme limit of its throw in either direction, but will enter the opening in the lever' 6l when it is between these limits.

In the drawings in Fig. 4 the completed article is shown after the pressure of air has forced it against the inward sides of the separable or blow mold, the glass product being shown by solid cross-section lines and the mold 37 by broken cross-section lines.

The operation of the machine is as follows: The plunger cross-head l0 is raised by admittn g air into the cylinder 2l under the piston and the sliding plate 35 moved to bring the blow-mold 45 under the axial line of the A suitable quantity of molten glass is then placed in the blank-mold 36, and the sliding plate 35 moved until the blank-mold plunger.

as to bring this blow-mold 45 under the axial line of the shaft S--in doing which the depending pin 5S in the bottom of the plate 35 will operate the crank 5,7, and thereby rotate the shaft 54 and swing the blow-arm over the top of the neck-mold and centrally below the Either lever 60 or 6l is then moved by the operator, allowing air to enter over the piston in the cylinder 2l, forcing down the plunger 9, the completed stroke of which is arrested by encountering the air-valve 56 on the blow-arm, which is thereby opened,

allowing the compressed air to enter the interior of the plastic blank in the blow-mold, thereby expanding it in all directions to assume whatever configuration is therein impressed. The operator then moves the handle 44, opening, the neck-mold, and then by means of either lever 60 or 6l admits air un- ,mold and permits a ready removal of the completed article therein. n
