To all whom it may concern:

Be it known that I, WILLIAM G. BOGEN- sonurz, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Flasks, of which the following is a specification.

This invention relates to improvements in flasks.

My invention relates particularly to the guides for the flask members and means i' r manipulating the parts.

he main objects of this invention are to provide in a flask an improved guide .means which eflectively and accurately guides the parts into position and and easy assembling an their rapid disassembling without danger of injury to the mold which has been formed in the flask.

Further objects. and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

he structure described constitutes one effective embodiment of my invention. Other embodiments would be readily devised by those skilled in the art.

The invention is clearly defined and pointed out in the claims.

A structure constituting an eifective and preferred embodiment of the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a plan View of a structure embodying the features of my invention. Fig. 2 is a side elevationof the structure appearing in Fig. 1. Fig. 3 is an enlarged detail vertical section taken on a line corresponding to line 3-8 of Fig. 1, showing the arrangement of the guides. Fig. 4c is a detail vertical section taken on aline corresponding to line H of Fig. 2, showing details of the cope and parting plate lifting device. Fig. 5 is a detail horizontal section taken on a line corresponding to line 5-5 of Fig. 3, showing details of the guide. Fig. 6 is a perspective view of a hinged flask emmy invention, a parting plate being shown in connection therewith. Fig. 7 is a perspective view of the structure of Fig. 1 partially open to show the relation of the parts. Fig. 8 is an en- ,(permits their rapid I bers having a knuckle 9 adapted to engage 100 ters refer to similar larged detail vertical central section through the structures shown in Figs. 6 and 7. Flg. 9 is a vertical section taken on a line corresponding to line 9-9 of Fig. '8 showing details of the hinges. Fig. 10 is a detail perspective showing the hinge members separated. Fig. 11 is a plan view showing my improved guide applied to a flask having no hinges, the structure illustrated being a snap flask, the parting plate being omitted. Fig. 12 is a detail vertical section taken on a line corresponding to line 1212 of Fig. 11.

In the drawings, similar reference characparts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the drag and 2 the cope of a flaskof common type. The partin plate 3 is arranged between, the drag an cope in the well known manner.

In the structure illustrated inFigs. l to 5 inclusive, I show my improved lifting device for the cope and parting plate. In the structure shown in Figs. 6 to 10 inclusive,

show my improved guide applied to a hinged flask; that is, the drag, parting late and cope are provided with hinge mem ers, so that the cope can be lifted on its hinge to permit the removal of the parting plate. In the structure shown in Figs. 11 and 12, the hinges are omitted.

The co and drag here illustrated are the snap flas type; that is, the sides are hinged at .4: and are provided with catches 5. The details of these hinges and catches are not illustrated, as they may be of any desired construction. Where hinges are used, they preferably consist of the arm-like hinge members 6 for the drag which are offset upwardly and provided with

knuckle sockets

7 and 8. The parting plate 3 is provided with upwardly offset arm-like hinge mem-' the sockets 8 of the drag hinge members and an upwardly facing socket 10 adapted to receive the knuckles 11 of the cope hinge mem bers, the knuckles 13 of the arm-like hinge members 14; of the cope being adapted to 1 engage the sockets 7 of the hinge members 6 of the drag so'that the cope swings clear to permit the removal of the parting plate and when the cope is closed with the parting plate in position the parts are all properly supported and they are also properly supported when the partin plate 1s removed.

Where the parting time is used my improved guide consists of the guide rigid member 15 on the dra which is adapted to receive the guide mem er 18 on the parting plate. The guide member 17 on the cope is adapted to receive the guide member 15 on the drag. These members are all preferably V-sha ed in cross-sections, as illustrated, as they t ms serve more effectively to guide and center the parts. The member 18 is yieldably secured by means of the spring 16 which is secured at a central point to the parting plate and at its ends to the guide, so that the guide is yieldingly supported to permit its engagement with the guide 15 when presented thereto with a swinging movement, as when the flask parts are hinged, or in the event that they are not presented in assembling in an exact horizontal relation to each other. Thus arranged the guide 18 is yieldingly supported, and at the same time it serves its full purpose as a guide, permitting the assembling and disassembling of the parts rapidly and without danger of the guides being wedged in either assembling or disassembling, and, further, the parts are so guided that they can be disassembled with little danger to the mold, which has been formed, being injured. .The

, guide 17 on the cope is preferably adjustably sup orted on the yoke-like frame 19, the

' arranged to gm e being slotted at 20 to receive the screw 21, and an adjustin screw 22 being arranged throu h the en of the frame. (See Fig. 3%) The handle 23 is arranged so that it can e grasped readily without interference with the uides or to assist in freeing the flask memdiers. In the structure shown in Figs. plate is not used, the yielding guide memer is mounted on the drag.

I referably provide an improved device for rawing the cope and the parting plate, as is shown in the preferred construction in Figs. 1 to 5. This embodiment illustrated consists of the levers 24:, which are pivoted at 25 on the sides of the drag 1. A pair of coactin levers 26 are pivoted at 27 to the sides 0 the drag, and to the levers 24 at 28, so that all the levers are actuated together.

.The outer ends of the levers 24 are preferably connected, so that they may be conveniently actuated together. The

levers

24 and 26 are provided with hearing portions 29, on which the rollers 30 on the cope 2 rest. The parting plate 3 is provided with rollers 3l,which are engaged by the levers 24c and 26. The bearing portions 29 of the levers are preferably oiiset and the rollers 31 are be engaged by the levers between the rollers 30 and the lever pivots, so that the cope is elevated more than the parting plate, thus not only lifting the parting 11 and 12, where the parting eeaeei plate from the drag, but separating the cope from the -parting plate. The flask, when equipped with this device and my improved coacting guide, is capable of very rapid manipulatlon.

I have illustrated and described my improvements in detail in the form in which I have embodied them in practice, as I find that embodiment to be highly satisfactory. I am aware, however, that my invention is capable of considerable variation in structural details and I wish to be understood as claiming the same not only in the specific form illustrated, but broadly as well within the scope of the appended claims.
