Application led June 28, 1915. Serial No. 36,768. I
To all whom t may concern.:
Be it known that I, JOHN W. BRADLEY, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Wax Presses, of which the following is a specification.
My invention relates to improvements in wax presses, and it has for one of its objects the provision of a press of this type in which a cake of core wax is to be inserted and be pressed therefrom in strands of the desired thickness and length.
A further object is to provide means for retaining the cake of wax at the escape points of the press in a softened condition during the pressing operation so that it will be more freely pressed from the container into strand form.
A further object is to provide a press of this type in which thc container may be quickly and easily reloaded and in which provisionA is made for insertion thereinto of a wax cake or square of rectangular formation in cross section, it being the intention that these cakes be supplied to the owners of presses and be inserted by them into the container of the press which is also of square or rectangular formation in cross section to conform to the shape of the wax cakes; this being a decided advantage in the shipment of the wax cakes, since by forming them of square or rectangular shape in cross section they will more readily retain their shape during transportation and therefore be at all times in condition to be inserted into the container of the press.
A still further object of my invention is to provide interchangeable dies which may be easily removed from the press and others of different form and size of openings substituted therefor when desired.
Other objects are to provide simple and effective means for locking the container in alinement with the power medium employed, to position the wax container in the frame so that it may be tilted for insertion thereinto of the wax cake; and to otherwise improve on presses of this type now in use or known to me.
With these objects in view the invention consists in a suitable frame or support, a wax container preferably of square or rectangular formation in cross section, and means for pressing the wax within the container through suitable dies provided for forming the wax into comparatively thiny strands, the strands thus formed being used to vent cores.
It further consists in a suitable support, a wax container adapted to be pivotally mounted in said support, so as to permit the ready insertion thereinto of the wax, anda screw power device movable within the container when in normal position.
It further consists in the provision of a novel heating device for heating the wax to the ejecting point of the container, and in the novel interchangeable dies associated with the container.
It also consists in the novel features of construction and in the arrangement and combination of parts to be hereinafter described and more particularly pointed out in the subjoined claims.
In the drawings,
Figure 1 isa front elevation of a press embodying my invention in a representative form. Y l
Fig.`2 is a side elevation of the same.
Fig. 3 is a central vertical section taken on line 3 3, Fig. 1.
Fig. 1 is a horizontal section taken on line 4 4, Fig. 1.
Fig. 5 is a horizontal section taken on line 5 5, Fig. l.
Referring t0 the drawings in detail, like numerals of reference refer to like parts in the several figures.
The reference numeral 6 designates a frame or support comprising two spaced members 7, 8, which are connected at the top by inturned portions 9, 10, through which bolts 11 are passed to secure the upper ends of said members together. The abutting edges of these inturned portions have semicircular sockets which register and form an opening 12 through which is passed the hub 13 of an actuating handle 14, said handle comprising two bars 15 directed oppositely from the hub 13. As clearly shown in Fig. 3 the hub 13 has an annular groove 16 in which the inturned Lportions of the members 7, 8 are fitted so that the handle cannot be moved within said frame except in a rotary manner. The hub 13 of the handle has a central threaded opening 17 into which is threaded a power screw 18 having a plunger 19 at its lower end, said plunger and the lower portion of the power screw being en;
tered in an elongated container 20 in which the wax 21 in cake form is placed. The
At 24 the spaced members of the frame are provided with inwardly-directed stop lugs, against which the rear side of the wax container 20 bears near its upper end, and projecting forwardly from said spaced members near the lower vend of said container are two forwardly-directed arms 25, 26, which terminate in inwardly-directed stop portions 27, 28, respectively, said stop portions being spaced from the container when the latter is in normal or vertical position with its rear face in contact with the stop lugs 24, as clearly shown in Fig. 3. rlhe container 2O has at its lower end a hollow casting 2 which has an upwardly-projecting portion 30 of a size tov fit into the container, and said casting is cored out to provide a water chamber 3l which has an opening 32 in its upper wall for the purpose of lling said chamber with water. The container is preferably of square or rectangular formation in cross section, as this will enable the cakes of wax of square or rectangular formation to be inserted Jdiereinto, said formation of the wax being found desirable for shipping purposes since when lying on one of its sides in transportation, it will not so readily lose its cross sectional shape as would be the case if the cakes were made cylindrical or oval, and since the container is preferably of square or rectangular formation, the upwardly-directed extension of the casting 29 orbase member, as it may be termed, is of like formation so as to snugly fit within the container." rlhe base member may be said to form part of the container and is so to be considered in the subjoined claims, unless specically referred to therein.
'and by means of these trunnions the wax container 20 is supported in the frame. At-
Lacasse tention is invited to the fact that the openings 38 in said spaced members 7, 8 are square at their upper ends, as at 39, Fig. 2, and the trunnions have at their outer extremities the angular downwardly-directed aortions 40. B f reason of such formation-V l 3 of the openings 38 and trunnions 37 it is necessary that the base member 29 be inverted so that the angular portions 40 of the trunnions register with the angular upper ends of the openings 3S. This enables the trunnions to be passed through the openings, or the latter over the trunnions, as may be found necessary, and when the trunnions are properly placed within the frame, the base member 29 may be turned into normal position so as to bring the angular portions 40 in a downwardly facing direction in which position the trunnions 37 are prevented from being drawn out of the openings 38, due to said angular portions 40 bearing against the outer sides of the spaced members 7, 8, as clearly shown in Fig. 2.
The spaced members 7, 8 of the frame have rearwardly and downwardly-directed arms 4l at their lower ends which terminate in inwardly-directed portions 42 on which is seated an oil lamp or other burner 43 adapted when lighted to have its llame play against the underside of the hollow base member and heat the water therein, which in turn keeps the metal surrounding the passages 34 in said member in heated condition and consequently the wax forced therein in a soft state. ln order, however, that the heat from this burner does not directly come in contact with the wax strands as they are forced through the die members 35 a guard 44 is secured or otherwise applied to the underside of the base member, Vsaid guard conlining the heat from the burner to a region at one side of the wax strands as they are forced from the members.
ln line with the stop lugs 24 on the frame, vforwardly-directed arms 45 are provided which have upwardly opening notches 46, and in these notches a lock device 47 is journaled, said device comprising a transverselydisposed spindle 48 having its ends journaled in said notches and having at an intermediate point a cam portion 49 adapted to bear against the front wall of the container 20 and lock the latter in vertical position, in which position the power screw 1S and plunger V19 are held in operative relation therein. Said spindle 48 has an outstanding handle 50 by means of which it may be conveniently rotated so as to lock the wax container in position, or to disengage said lock device from the container and permit its removal from the arms 43. When the lock device 47 is removed from lthe forcontainer by elevating the power screw 18, the container may 'be swung or tilted forwardly, as shown in dotted lines in Fig. 3, this being permitted by reason of the base member being pivotally supported in the frame. The extent to which said container is tilted is, however, limited by the stops 27, 28 which the container strikes in its movement. When the container is tilted forwardly, as shown, a cake of wax may be easily inserted thereinto, and after tiltingA the container into rearward position and locking the same by the lock device 47, the handle 14: may be rotate'rl to move the plunger 19 downwardly into the container and in contact with the upper end of the wax cake. The lower end of this wax cake will become heated suiiiciently by contact with the base member to cause it to be easily forced into the passages 34:, 36, respectively, of said base member and said die members 35 and be ejected from said members in the form of wax strands, which may be formed in any desired lengths and stored for use, or which may be cut ofi and used as needed. It is of course to be understood that my invention would not be departed from if the container were made cylindrical or otherwise and the plunger formed accordingly, and other changes in construction may be resorted to without departing from my invention or sacrificing any of the advantages thereof.
Having thus described my invention, what l claim is,-
