INVENTORS nurse JAMES H. DAN YER, OF BEAVER, AND WILLIAM H. LOSE, F ZELIEN OPLE, PENNSYLVANZ-dz- GUIDING DEVKCE F63 MGLDING fiPPAIR-ATUS.

To. all whom it may concern:

Be it known that we, JAMES H. DANVER and \VILLIAM H. Loss, residents of Beaver and Zelienople, respectively, in the counties of Beaver. and Butler, respectively, State of Pennsylvania, have invented a new and useful cast molds for bath-tubs, whereby the flasks and atterns when brought to position for forming such molds will be in perfect line to register with each other and properly positioned in place, so that the positioning of the molds with relation to each other will form an even thickness of metal in the articlc' when cast.

v A Our invention consists, generally stated, in

the novel arrangement, construction and combination of parts, as hereinafter more specifically set forth and described and particularly pointed out in the claims.

Toenable others skilled in the art to which our invention appertains to construct and use our improved guiding device or means for molding apparatus, we will describe the same more fully, referring to the accompanying drawing, in which- Figure 1 is a plan view. of a templet for use in connection with our invention. Fig. 2 is a side elevation of the same. Fig. 3 is a plan view of a bath-tub pattern showing the templet applied thereto. Fig. 4 is an enlarged plan view of a portion of said pat tern and templet. Fig. 5 is an enlarged sectional view of a portion of the pattern and templet on the line 55 Fig. Fig. (i is a sectional View of a portion of a flask showing the templet applied thereto. Fig. 7 is a tional view of the pattern and in position. Fig. 8 is an enlarged perspective view of the spool employed and showing in dotted lines where the same is cut 'to form half portions for the pattern. Fig. il'is a like view of one of the half portions.

Like symbols of reference herein indicate like parts in each of the figures of the drawing.

As illustrated in thedrawing, i represents Specification of Letters Patent. Application filed December 11, 1908. Serial No. 67,fi 83.

a pattern for forming bath-tubs, which is of the usual hollow shape and is provided with the lug portions 2 extending out from the match or stripping platel around saidpattern. Four of these lug portions :2 are preferably employed, with two of the same located on each side of the pattern 1 near the ends thereof and each is provided with an opening 3 through the same having an inner semi-circular portion 3 which terminates in a tongue 2 extending over each side of the same and formed on said lug portions. The

usual drag flask for these molds is shown at i having the usual flange 5 extending out from the upper end of the same and provided with the openings or holes 6 through the same.

7 indicates a templet, which is preferably in the form of a frame provided with a'central'opening 8 through the same and thereby forming the sides 9 and ends 10 thereon. At each of the four corners of the templet 7 is located a pin 11 which is provided with a circular enlarged portion 12 extending above said templet and with the circular contracted portion 13 fitting within a circular hole 14 in said templet and extending below the same. These pins 11. are removably secured in place in the holes let-of the templet in any suitable manneryas by a pin or bolt 15 extending through said templet and the contracted portion 13 on said pins.

16 indicates a spool, preferably formed of metal, which is provided with a flange l? extending from each end'of the same and a circular opening or hole 18 through the same.

' The manner of constructing, use and operation of our improved guiding means for molding apparatus is as follows-In forming the guides a for the pattern 1, two of the spools 1.6 are cut in half and on the dotted line 12) shown in Fig. 8, which will form four halves or segmental bearing portions 20, such as is shown in Fig. 9, and after the teinplet 7 has been placed under said pat-tern, as shown in Figs. 4: and 5, the enlarged portions l2 of the pins 11 on said templet will enter the openings 3 in the lug portions 2 on said pattern. After this is done the semi-circular bearing portions 20 are each placed in the semi-circular portions 3 of the openings 3 on the pattern 1 and against the enlarged portions 12 on the pins 11 insaid opening, so that tiny suitable filling material such as the Babbitt metal 21 can be placed in the spaces 22 formed around said bearing portions 20 in the portions 3 of said opening to hold said bearing portions inplace, and after which the templet 7 and pins 11 are removed to form the pattern guides or seats 18 in said portions 20 for the reception of the dowel pins hereinafter described and from the holes 18' in the spools 16. In forming the guides for the flask 4:, four of the complete spools 16, like the one shown in- Fig. 8, are used, and these spools have their holes 18 slightly smaller in diameter than such holes for forming the guides 18 in the semicircular bearing portions 20. After the templet 7 has been placed on the flask 4, so that the contracted lower ends or portions 13 on the pins 11 carried by said templet are within the holes 6 in the flange 5 or said flask, each of the spools 16 are placed in said holes and around said pin portions, and then a suitable filling material, such as the Babbitt metal 23 can be placed in the spaces 22 formed around said spools by said spools and holes to hold said spools in place, and after this is done the tem let and pins are removed to form the ask guides or seats"18v for the dowel pins hereinafter described.

The dowel pins are shown at 24 and they are each provided with an upper enlarged pointed end portion 25 and a lower con- I flask and in such lowering the guides or to its proper position on said flask and he precis y matched therewith to form a mold, which will enable an even thickness of metal to be had when the article is cast from such mold. I

It will be evident that our improved guiding device can be applied for matching any flask or pattern flasks and flasks or patterns,

life of the mold ports carrying the guiding means.

Various modifications and changes inthe design, arrangement and construction of our improved guiding device may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

What we claim as our invention, and desire to secure by Letters Patent, is

1. Means for forming guiding seats in a molding device, comprising the combination of a molding appliance having openings therein, with a temporary gage fitting in said openings, and bearing members secured in said openings and around said gage for forming said seats.

2. Means for forming guiding seats in a molding device, comprising the combination of a molding appliance having openings therein, with a temporary gage having pins thereon for fitting in said openings, and bearing members secured in said openings and around said pins for forming said seats.

Means for forming guidingseats in a molding device, comprising thecombination of a molding appliance having openings therein, with a temporary gage havin shouldered pins thereon for fitting in sai openings, and bearing members secured in said openings and around said pins for forming said seats of different size.

4. Means for forming guiding seats in a molding device, comprising the combination of a molding appliance having openings therein, with a temporary gage having removable pins thereon for fitting in said openings, and bearing memberssecured in said openings and around said pins for forming said seats.

5. Means for forming guiding seats in a molding device, comprising the combination of a molding appliance having openings therein, with a temporary gage having shouldered removable pins thereon for fitting in said openings, and bearing members secured in said openings and around said pins for forming said seats of different size.

In testimony whereof, we, the said JAMES H. DANVER and WILLIAM H. Lose, have hereunto set our hands.
