i UNITED STATES PATENTOFFICE;
WILLIAM H. MCCLELLANDyQF HUNTINGIDON, PENNSYLVANIA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO BOY P. M. DAVIS, OF MOUNT UNION, PENNSYLVANIA.
"ADJUSTABLE MOLD.
Applicationffiled December 15, 1924. Serial no. 755,936.
Be it known that WILLIAM H. MoCLEL- LAND, a citizen of the United States of America, residing at Huntingdon, in the county of Huntingdon and State of Pennsylvania, has invented certain new and useful Improvements in Adjustable, Molds, of which the following is a specification.
This invention relates to molds and more particularly to adjustable molds for making brick. j
In the manufacture of.;-molded brick where a slicker is used, the upper edges of the mold wears away under the action of the slicker until it has to be discarded due to the fact that the thickness of the brick mold therein must be under specified limits. As much as 95% of the original material from which the type of mold now accepted as standard in the industry is made, must be discarded as scrap when the mold becomes worn.
It is the object of the present invention to provide a mold which will not only have a much longer life but one Which will also obviate any, variation in the thickness of the brick due to wear of the mold. A further object of this invention is to reduce by half the amount of material to be discarded when the mold has reached the limit of wear.
In the accompanying drawings forming part of this specification:
Figure 1 is a plan view of a mold made in accordance with the invention;.
Figure 2 is a longitudinal sectional view through Figure 1, taken on the line 2-2;
Figure 3 is an end view of the mold, partly in section and partly broken away, showing the upper and lower sections of the mold as originally assembled before any wear has taken place;
Figure 4 is a view similar to Figure 3 but showing the two halves of the mold adjusted after use to compensate for wear; and
Figure 5 is an end View of an alternative form of mold showing the two halves thereof adjusted after use to compensate for wear.
Referring more particularly to the drawings wherein like reference numerals designate corresponding parts throughout the several views, 1, denotes a two part skeleton mold comprising upper and lower sections 2 and 3 respectlvely. These sections which are identical one with the other 1n size and construction, comprise side platest, end plates 5, partitions 6, and end braces 7.'
Any suitable fastening means such as screws 8, are employed to connect, the end plates 5,
The upper and lower sections of the mold I are heldtogether by means of bolts9, which pass loosely through openings 10, in the side and end plates of thelowersect-ion, and threadedly engage in corresponding aligned threaded openings 11, formed in the side and end plates of the upper section of the mold. The enlarged heads 12, of the bolts 9, are preferablycountersunk in the enlarged portions 13, of the bores of openings 10. These bolts 9, also serve as dowels to hold the two halves or sections of the mold together. Adjustment of the mold sections to compensate forthe wearing away of the upper edges of the upper section of the mold is effected in a manner hereinafter decribed by means of threaded bolts or dowels 14, which are threaded into bores 15, formed in the end plates 5, and loosely engaged at sary to face off the worn surfaces'of the upper section of the mold, after which the originalthickness is again restored by ad justing bolts '9 and 14 as previously described. 1
When the limit of wear has been reached the upper section 2, of the mold is discarded and a new section added, still retaining the lower section 3, which has had practically no wear.
In Figure 5, I have shown an alternative method of adjusting the thickness of the mold, this being accomplished by means of shims 18, held in place and compressed by bolts 9, the bolts 14, not being needed in this form of the invention. v V
Ithas been found in actual practice that the space 17, caused by the separation of the two halves of the mold has no harmful efi'ect on the quality of the brick due tothe fact that this space fills up with the material from which the brick is made. The shearing action caused by the ejection of the brick produces the same smoothness and texture on the surface of the brick as is the case with the standardmold heretofore used.
Having thus described my invention, what I claim as my invention is:
1. A two part skeleton mold comprising upper and lower sections, said sections each having side and end walls, andpartitions, means for aligning the wallsand partitions ofone'section with the walls and partitions of the other section, and meansfor adjusting said sections; into spaced relation with respect to each other;
lower section and screwing into the side and end walls ofthe'upper section, for connecting said sections together with their walls in alignment, and bolts screwing through the end walls of the lower section and engaging the end walls of the'upp'er section, for adjusting said upper section away from said. lower section;
flIn testimony whereof I aflix my signa- 'ture nrpresence of two witnesses. v
