HENRY FELIX GASTON, or CHICAGO, rumors, ssrenon To con'rinnnrnr. CEMENT TILE COMPANY, OF CHICAGO, ILLINOIS, a ooaroaari'on or DELAWAR EXTENSIBLE IVIQILJJ.v
T 0 all w/iom it may concern:
Be it known that I, HENRY FELIX GASTON, a citizen of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented new and useful Improvements in Extensible-Molds, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.
My invention relates to extensible molds that are employed for the casting of cement tiles of different lengths. My invention has special reference to a mold of the character indicated whereby tiles of cement or similar material and of different length, but'having peripheral flanges to form hollow channeh like slabs closed at both endsmay be economically and conveniently manufactured.
By means of my present invention, I provide an improved mold that may be utilized in manufacturingcement tiles which may be employed generally for roofing purposes. As is well known, cement tiles adapted for roofing purposes are supported on purlins which are comprised in the skeleton structure or :t'rame-work of the building. The distances ietween purlins in frame-works are by no means standard and vary according to the structures of which the purlins form a part. Therefore, in order to manufacture channellike closed end roofing tiles for the different spacings between purlins it has heretofore been necessary to have a separate mold for each length of-tile. It is, of course, obvious that it is economical to use as long a tile as p is compatible with good design and safety because fewer purlins are then required in the roof frame-work of the building.
Bymeans of my improved mold, I am able to manufacture tiles of different lengths from the same mold which is capableof adjustment to permit, of the casting therein of a tile of any predetermined length.
It has been the desideratum of tile manu facturers to provide hollow, channel-like tiles having closed ends, inasmuch as such a closed-end tile is capable of resisting greater dead weight and is not likely to be damaged during the handling thereof. By means of my extensible mold I am able to conveniently and economically manufacture closed-end channel-like slabs or tiles of different lengths.
In order to accomplish the foregoing objects and otherobjects that will be hereinmold of the general type shown in the accompanying drawingsand described in the following specification to which reference may now be had for a more complete understanding of my invention.
Fig. 1 isa plan View of an extensible iiiold embodying a form of my invention;
Fig. 2 is a contracted and longitudinal cross-sectional view taken along the line 22 of Fig. 1;
Fig. 8 is a transverse sectional view taken along the line of Fig. l 5
I Fig. 4 is a view in perspective of aclosedend channel-like slab or ,tile which 'is cast in a mold of the character shown in Fig. 1;
nel-like slaps or tilesof the character illustrated in Fig. 1.
The extensible mold of Figs. 1, 2 and. 3 comprises twobody portions 1 and 2, each of 1 after apparent, I have invented an extensible is a view showing how two molds which is provided with a central expanded elevation which is flanlred on two sides and one of its ends by means of latei'ally extending flange portions 3. The body members 1 and 2, are placed end-to-end, their open ends, as shownin Fig. 2, being opposed to each other, These body members are adapted to telescope within each other whereby the elevated expanded portions of both body members merge into each other to form one continuous central elevation'for the mold as shown particularly in Fig. 3. Similarly, the flange portions 3'foi'med at the sides of the body members 1 and 2 merge into each other and, in conjunction with theflange portions 3 formed on the outer ends of the body members 1 and 2, form a continuous peripheral flange for the abovefimentioned central ele vation of the mold.
In setting up the mold, the two scoopshaped body portions'l and 2 are placed upon angle-irons 1 and 5 as shown in Fig. 3, the flange portionsfG of, the angleirons subtending the horizontal flanges 3 of the body members 1 and 2. At the ends ofthe mold, angle-irons 7 and 8 are disposed, as shown in Fig. 2', the horizontal flanges 9 thereofresting .upon the flange portions 3 formed at the ends of the body members. 1 and 2. In this fashion a pcripheral trough 10, is formed in the mold which completely surrounds the central elevation of the mold on both of its sides as well as its two ends. The angle-iron side members 4: and 5 and the angle-iron end members 7 and 8, when properly positioned relative to the flange portions 3 of the body members 1 and 2, are held in position by means of clamps 11 or any other suitable devices. Each of the body members 1 and 2 is reinforced at its expanded or arched portion by means of channel irons 12 that extend transversely of the mold as shown in Fig. 2.
After the mold is assembled, the two body members 1 and il'being telescoped to the proper degree, depending upon the length of the tile desired, cement or othcrsuitable material is poured into the mold. Then this material has become properly set the mold is emptied of its contents and a closedend channel-like. slab of tile, of the general form illustrated in Fig. l. is the result.
By referring to Fig. at it will. be noted that the tile comprises a central hollow portion 13. that is flanked on its sides by the walls 14 and on its ends by the end walls 15. It will, therefore, be observed that the hollow tile of Fig-ft is a product resulting from the mold liereinbefore descr bed. It is also obvious that tiles similar to that shown in Fig. but of different lengths, may be cast in a mold constructed in accordance with my invention, since the body members 1 and 2 are capable of being telescoped to accord with, the length of tile desired.
lVhen it is desired to simultaneously cast several channel-like slabs or tiles in molds embodying a form of my invention, mold sections 16 and 171 may be arranged side by side as shown in Fig. 5. In this instance, an inverted T-shaped iron 18 is placed between the two mold sections, the flanges 3 thereof resting upon the base of the T. The T-iron 18, therefore, forms a single side member or wall for a compound mold and is common to both mold sections.
While I have described herein one form of my invention it is understood that I do not desire to have any limitation imposed thereupon except as specifically set forth in the appended claims, or required by the prior art, since mechanical expedients or equivalents of the various elements of my mold may be evolved which come within the scope of my invention.
Having thus describedimy invention what I now claim as new and desire to secure by Letters Patent is:
1. An extensible mold for cz-isting closedend channel-like slabs which comprises two pairs of spaced substantially parallel angleirons arranged in the form of a parallelo gram having facing horizontal flanges and upstanding welirportions, and two inverted scoop-shaped body members disposed endtoend and adapted to'telescope within each other, said body members being severally provided with laterally extending portions along the edges of their sides and exposed ends. said laterally extending portions overlapping said flanges and forming together with said body members and web-portions a peripheral trough around the mold.
2. An extensible mold for casting channellike slabs which comprises two spaced substantially parallel angle-irons having facing flanges, two facing inverted scoopeshaped body members telescopically slidable 'together along said flanges, and angle-irons resting upon the exposed ends of said body ineml rs transversely of and between said first, named angle-irons, said angle-irons serving to form with said body members a continuous trough around the periphery of the mold.
3. An extensible mold for casting closedend channel-like slabs which comprises two pairs of spaced substantially parallel angleirons arranged in the form of a parallelogram and having facing horizontal flanges and upstanding wel:)-po- 'tions, and two inverted scoop-shaped body members disposed end-to-end and adapted totelescope within each other, said body members being severally provided with laterally extending port-ions along the edges of their sides and exposed ends, said portions being of a width suliistantially equal to the width of said horizontal flanges and saidportions fully overlapping said flanges thereby forming together with. said body members and webportions a peripheral trough of predetermined dimensions around the mold.
In witness whereof,l have hereunto subscribed my name.
