Application filed August 4:,

To all whom it may concern: l

Be 1t known that I, 'VVILLIAM Annunin Jamestown, Chautauqua county, State of New York, have invented certain new and useful Improvements in Molds, of which the scription as willenable any one skilled in the art to which it appertains'toinake and use the sa'me,'reference being had to the ac companying drawings, forming part of this specificatio I A My invention relates to molds-orflasks for .vention in this class of devices in connection with a mold Stlltfilblfor casting metallic sled shoes, though the invention, of f'c'ourse,

The principal objects of the presentinvention are to provide a newmethod for casting v in molds; reinforced or strengthened articles, such as iron sled shoes andto produce there may light weight and great strength. iiVith'tl'iese" and other objects in view, my invention consists in the Various 'novel'and peculiar steps in the method and the ar-, rangements and combinations ,of' the different parts of the mold, all as hereinafter fullyset forth and then pointed out in the claims.

I- have=illustrated my'invention in the ac- Figure 1 1s a central longitudinal sectional View of my improved mold shown with the hollow. metallic lining or bushings forthe perforations in the .castlbody, as in place, likewise the longitudinal strengthenin 1nem-. bers, the mold being ready for receiving the molten material to produce the casting. Figs. 2 and 3 are views of cross sectionsof indicated by lines 2-2' and 3-3, respectively, in Fig. 1. Fig. 4 is a perspective View of a cast metal shoe containing thevertical metallic. linin s or bushings in th'e perforations thereof and the longitudinal strengthening members, the latter :being View in plan showing the relative locations of the hollowmetal linings or bushings and the longitudinal strengthening members. Fig. 6 is a perspective View of 'aportion of a modified form of the'reinforce members, in the way of the wires twisted "upon themspecification of Letters Patent.

selves with the metal linings and bushings bet-ween thetwisted parts of the same.

Referring. to the drawings injwhich like numbers of reference designate. like parts throughout, 1 is the main and'low'er part of the mold having the matrix cawity or chame her 2 and with'it-s upper edges rabbeted at 3 to receive the'oover or upperpart of the mo'ld- 4. Thetwo parts 11 and 4 of the mold part 8 hav ng, a central perforation 9 through which passes a screw-threaded rod '10 which; is provided upon the exterior of the yoke with a tightening nut 11 having peripheral holes'l2 therein for receiving a. tool or part by which the nut isturned. The inner end of the screw rod 10 is bent at 14 for detachable engagement with the socket formed in a bracket 15"which is mounted upon the outer face of the adjustable end member 16 of the mold. This adjustable end member 16: is designed 'to [it snugly within' the casting chamber 2 andso, asto be movable longitudinally therein toadjust it for the desired length of the article which is to be'cast, and the screw rod 10 is made ofsuflicient length to .permit of the desired range of movement-of the piece 16. By setting the movable end 16' at the desiredpointin the casting chamben-thelength of the cast articleis determined and the position of this piece may be varied to vary the length 'of the article. Within'the 'casting chamber 2 are strung reinforce members or rods .17 which Figs 1, 2, 3 and lare.

shown as consisting in met-allicwireseach of wh ch passes through a perforation 18 in one-end; of the part l of the moldand is provided with a set screw 19 for clamp ng the end. of thewiretherein. The other end of each wire passesthrough a perforation 20 in the movable'end l6, and thewires are twisted or tied at 21 upon the'exterior of the movable part -16.' Thereinforce members 17 being firstsecured in the movable part 16 and the latter then. set in theposition in rammed MarQS, 1910.

which it is to be used. in the mold, the refinforce members 17 are drawn tautat't he ends extending through the perforation 18 andare then clamped by the set screw 19. Under this condition, a slight- .turning of the-nut 11 on the screw rod 10 will make sure of the reinforce members 17 being taut. In this way the movable end 16 serves the double function of determining the length of y the article to be cast and assisting in tautenmg the reinforce members.

In casting'iron sled shoes, the same are formed with tapering vertical perforations, for receiving attaching rivets or screws by means of which the shoe is held in place for use. In order to form these vertical perforations in the shoe, I providea set of hollow tapering or conical bushmgs or linalso 1s an important feature of the present improvement and I have found that it gives excellent results. After the cast article is removed from the mold with the plugs 23 in the bushings 22, the plugs are knocked out for subsequent use in casting other articles.

The top or cover 4 of the mold is provided near one 'ofits edges with apouring hole 24: through which the molten metal is poured into-the mold when the same is closed for the casting'process. At one end of the mold between .the cover and corresponding end of the body of the mold is formed another pouri'ng hole 25 into which the metal is also introduced in order to fill the high point in the matrix chamber 2. Upon the exterior of the cover at is formed a longitudinally extending rib 26 for strengthening the cover and this rib also serves as the attaching point for the straps 27 which are riveted at 28 thereto. A rod 29 is inserted in the straps 27 so asto provide a convenient handle for the cover. I

In Fig. 5, the reinforcing members 17" are shown'as fiat bands or strips of metal,

50 instead of the ordinary wire.

In Fig. 6 the reinforce wires 17 are twisted upon each other and between the twisted strands of the wires are placed con- 1 ical bushings or linings.

In Fig. 4 Ihave shown a cast iron sled shoe having the reinforce wires 17 running longitudinally through the same and the metal linings or bushings 22 secured in the vertical perforations of the shoe 30, ready for use.

It will, of course, be understood that modifications may be matle in the various difierent parts of the improvements herewith set forth, without, however, departing from the spirit of the invention.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. A mold comprising a base member channeled or recessed to form a castin chamber open at one end, a cover, a movable part adjustably mounted in the open end of said chamber and adapted to vary the length of the casting. a screw-threaded rod engaging said movable part. a detachable yoke or piece through which said rod loosely passes and adapted to be mounted across the open end of said chamber, and a nut on said threaded-rod acting against said yoke or piece as an abutment.

A mold comprising a casting-chamber and acover therefor, one end of said chamher being open, a movable part adjustably mounted in the open end of said chamber, a screw-threaded rod engaging said movable part. a detachable yoke or piece through which said rod looselvpasses and adapted to be mounted across the open end of said chamber, and a. nut on said threaded-rod acting against said yoke or piece as an abutment.

3. A. mold comprising a casting-chamber and a cover therefor. and movable hollow conical bushings or linings adapted to be placed on end in said casting-chamber at any desired point therein and cast in the article, and means for regulating the length of the casting.

l. A mold C0111] T)1lSlllg a base member channeled or recessed to form a casting chamber having an integral wall at one end to close the same at-thatpoint and open at the other end, a movable part adjustably mounted in the open end of said chamber and means for adjusting it in said chamber, reinforce imunbers adapted to extend through said casting chamber the closed integral cud of said chamber being formed with apertures for receiving the reinforce members and set-screws projecting into said apertures for engaging and holding said reinforce members, the said movable part beingprovided with means for attaching thereto the other ends of said reinforce members and said -part acting to stretch said members during the casting.

In testimony whereof, Ihave hereunto set my hand in the presence of the two subscribing witnesses.
