MULLIN, or RICHMOND, MISSOURI.
Application filed February 5. 1920. Serial No.
To all whom it may] concern: 7
I Be it known that I, F RANK CREAsoN, a citizen of the United States, residing at Richmond, in the county of Ray and State of Missouri, have invented certain new and Improvements in Corner Block Molds; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to that, class of molds designed for constructing cement building blocks and the present showing is designed for the manufacture of corner blocks to be used in conjunction with the wall blocks formed by the mold disclosed in my pending U. S. application,.Serial #309,809, filed on or about July 10, 1919. H v
The principal object of the invention is to provide a mold of'simple and inexpensive nature, yet one which will behighly efficient and desirable in forming corner blocks having air circulating passages in their upper and lower sides and their inner ends, while their outer ends are of solid formation to present the proper appearance at the corner of the wall. l
Vith the foregoing in view, the invention resides in the novel featuresof construction and the unique association of parts hereinafter described and claimed, the descriptive matter being supplemented by the accompanying drawings which form a part of this application. 4 p l I Figures 1 and 2 are elevations of opposite sides of a mold constructed in accordance with my invention. v
Fig. 3 is a top plan View.
Fig. 4 is an end elevation.
ig. 5 is a central vertical longitudinal section. I
Fig. 6 is a horizontal ection on the plane designated by line 6-6 of Fig. 1.
Fig. is a vertical transverse section on the plane indicated by line 7-7 of Fig. 3.
Fig. 8 is a perspective view of one of the transverse partitions.
In the drawings above briefly described the numerals 1 and 2 designate the parallel vertical sides of the improved mold; the numeral 3 has reference to the ends of the mold, and 4 designates a plurality of partitions extending between the sides land 2.
The side 1 is formed from a single sheet Specification of Letters Patent.
Patented July 2t, 1920. 356.473.
metal plate stamped inwardly along its longitudinal center to form a rib 5, the upper edge of said plate being by preference bent outwardly at 6 to form a reinforcing flange, while the lower edge of said plate is inwardly bent at 7 to provide a combined reinforcing and pallet supporting flange 7. Short vertical bars 8 preferably span the inwardly stamped rib-forming portion of the side 1 and are secured thereto, while a central longitudinal bar 9 is riveted or otherwise secured to said bars 8. The ends of bar 9 extend beyond the ends of the mold and are shown provided with nuts 10, for a purpose to appear.
The. side 2, as shown, includes a sheet metal plate 11 having its upper and lower edges bent outwardly to, provide reinforcing flanges 12, said plate being reinforced centrally by a longitudinal bar 13 whose ends extend beyond the ends of the mold and are provided with openings alined for the nuts 10. Transverse screws 14 pass through the openings of the bar 13 and are threaded into the aforesaid nuts, wherebytightening of said screws will clamp the sides 1 and 2 tightly against the ends 3 and the partitions at. lVhile screws are preferably used in connecting the two sides of the mold, it will be obvious that other forms of tie rods could well be employed.
The inner ide of the side plate 2 is provided with spacing plate 15 parallel therewith, said spacing plates and side plate being spaced apart by lateral flanges 16 on the former, which flanges are suitably secured to the side plate.
Each of the ends 3 preferably consists of outer and inner sheet metal plates 17 and 18 respectively, the former being disposed throughout its area in the same plane, while the central portionof plate l8,is inwardly stamped throughout the greater portion of its length to provide an inwardly extending rib 19. The two plates 17 and 18 may be secured together in any preferred manner and if desired their upper edges may be clenched together as indicated at 20.
One end of the rib 19 terminates at one vertical edge ofthe end member 3 and said rib and end member are here provided with notches 21 receiving the rib 5, while the opposite vertical edge of the end member 3 abuts flat against plate 11. Outward shifting of the two members 3 is prevented. by
' and 2, and inward'shifting of said end memhere is prevented by certain of the spacing plates 15. The partitions 4k are constructed similarly to the end members 3, said partitions being each formed of vertical plates 23 secured against each other with their central portions stamped outwardly to form ribs 24. These ribs, as well as the ribs 19 terminate in spaced relation with the side 2 and are by preferenceprovided with beveled ends 25 as shown. These ends 'may be formed of separate pieces of metal or otherwise, as occasion may dictate. The ends of the partitions 4:, beyond the ribs 24, are received in the guide-ways formed between the adjacent ends of the spacing plate 15, while the opposite ends of said partitions are formed withnotches 26 receiving the rib 5.
The upper edges of the plates 2-3 may be clenched together at 27 while the lower edges thereof are by preference bent outwardly at 28 for the support of pallets 29 upon which the blocks are cast. These pallets are also supported in part by flanges 80 on the lower edges of the end members 3, and all of the flanges 28 and 30 rest on the flange 7 as depicted in Fig. 7.
By constructing the device as or approximately as shown and described it may be easily and inexpensively manufactured and will be highly efficient in use. The mold is set up as shown and the green cement is poured into the spaces between the several partitions and between said partitions and the end members 3, and when such cement sets sufliciently, the screws or tie rods 14 are released and thus the mold may be knocked down for removing the blocks. The rib 5 forms a transverse groove in one end of each block and the ribs 24 formlongitudinal grooves in opposite sides of said blocks from their inner ends to points adjacent their outer ends. These blocks are adapted for use at the corners of walls formed of the blocks constructed by the mold of the application above referred to, and the several grooves of the corner blocks register with corresponding grooves of the other blocks to produce air circulating passages between the several tiers.
Since probably the best results may be obtained from the details disclosed, they may well be followed, but within the scope of the invention as claimed, the device may I side, while the inner side of the other member is'formed with vertical guide-ways, and a plurality of end and partition members extending between said side members, one end of said end and partition members being received in said guide-ways, while their other ends are provided with notches snugly receiving said rib.
2. A structure as specified in claim 1', said end and partition members being each formed of two-sheet metal plates secured together with outwardly stamped portions forming longitudinal ribs, the aforesaid notches extending through one end of said ribs and the other ends of these ribs being beveled.
3. A cement block mold comprising a side plate stamped inwardly along its longitudinal center to form an internal rib, vertical bars spanning the inwardly stamped portion of said side plate and secured to the outer surface of the-latter, a longitudinal bar secured to said vertical bars and extending beyond the ends of said side plates, a second side plate, a second longitudinal bar secured to the outer surface of said second side plate and extending beyond the ends thereof, spacing plates secured to the inner surface of said second side plate, inwardly extending stop flanges on the ends of the two side plates, end and partition members extending between said side plates and provided at one end with notches receiving the rib of said first named side plate, said end membersabutting said stop flanges and certain of said spacing plates, and said partition members being received between the other spacing plates, and tierods extending between the projecting ends of said first and second named longitudinal bars;
In testimony whereof lhhave hereunto set my hand.
FRANK GREASON.
