ANTON BERG, OF CHICAGO, ILLINOIS.
MOLD FOR BRIVOK-MAOHINES.
SPECIFICATION forming part of Letters Patent No. 607,787, dated J' uly 19, 1898.
Application filed July 20, 1896. Serial No. 599,780. (No model.)
To a/ZZ whom, it may con/cern.-
Be it known that I, ANTON BERG, a citizen of the United States,residin g at Chicago,in the county of Cook and State of Illinois, have invented certain newT and useful Improvements in Molds for Machines for Making Bricks, Tiles, dac. ,of which the following is a f ull,clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to certain new and useful improvements in sectional molds for brickpresses; and its primary object is to provide a sectional mold all the sides of which may be simultaneously adjusted to maintain the proper dimensions of the mold-space.
A further object of the invention is to provide a sectional mold, the walls of the molding-space being removable and adapted to be adjusted so that the proper area and dimensions of the molding-space may be preserved after the parts have been worn and then planed down and trued in a manner common in the art, and a still further object of the invention is to provide removable sides and ends adapted to be assembled to form the .molding-spaces andV means for clamping the sides and ends together in a firm and rigid manner.
My invention consists in certain peculiar novel features of construction and arrangement of parts, which will be fully hereinafter described and claimed in connection with the accompanying drawings, in which- Figure lis a top plan view of a mold-table embodying my invention and partly in section to show the adjusting means. Fig. 2 is a side elevation of the mold-table. Fig. 3 is a sectional view on the line 3 3 of Fig-1. Fig. t isa transverse sectional view on the line 4 4 of Fig. l.A Fig. 5 is also a transverse sectional view taken through the center of the molds on the'line 5 5 of Fig. l, and Fig. G is a perspective view of one of the sides of the mold.
My invention may be embodied in a single nioldybut for the purpose of illustrating a common form I have shown in the drawings a mold comprising four compartments, each of which is of substantially the same dimensions and construct-ed in the same manner, as shown.
Referring particularly to the drawings, A designates the mold-table, which may be of any preferred form and size, my invention not being limited to any particular form of table, as it can be embodied in tables of various descriptions. The mold-table is formed in two parts, as shown in the drawings, and has the two sides a, which are provided with extensions a beyond the sides of the table proper. These sides a are of substantially the same form and size and they constitute the sides of the mold, the compartments of the mold being located between them.
y Each compartment B of the mold comprises the side plates b and the end plates b', the said end plates being located between the side plates. The ends of the side plates are provided with tongues C, which fit in grooves c on the inner opposing faces of the mold'- side a, and the end plates b are also provided with tongues c', which fit in the same grooves, so that the end plates and side plates will be maintained in their proper relative position in the mold. j
At each end of the mold is an end block D, which is provided with tongues adapted to fit and slide in the grooves c on the inner faces of the sides a, and each end block is provided with a groove d in its outer face, having a beveled vertical side d. A wedge E is arranged to operate in the groove d in each of the end blocks D, and these wedges are provided with threaded bolts c at each end, which project through openings e in the extensions a and carry. the adj Listing-nuts F. These' nuts F bear upon the sides of the extensions and are operated to adjust the wedges E for the purpose of tightening the side plates and end plates which` form the compartments in the mold.
The side plates and end plates b b are made of metal, preferably having smooth faces, and as these faces become worn from constant use the plates may be removed and planed down or otherwise trued. The plates are then replaced in the mold in the manner described, and it will be observed that when the sides a and end blocks D of the mold are simultaneously adjusted and tightened, by operating the wedges E the plates b b will be forced tightly together and the same dimensions of each compartment preserved, it being understood` that the end plates ZJ and the side plates l) will be moved inwardly by IOO ments are changed the plun gers of the brickpress must be correspondingly adjusted to register with the changed position of the compartments or changed to correspond with the changed sizes of the compartments.
The WedgesE are adjusted very easily by.
operating the nuts F, and great pressure can be brought to bear upon the side plates and end plates b b' by the simultaneous adjustment of the sides a and end blocks D of the mold, this simultaneous adjustment being accomplished by reason of the fact` that the nuts F bear against the outeriaces ci the eX- tensions a, and the wedges E, to which the bolts e, carrying said nuts, are secured, operate in the grooves and bear against the beveled vertical side` d', the Wedges of course having correspondingly-beveled faces f to bear against the beveled sides d of the end blocks.
By reason of the fact that the adjacent side plates of two adjoining compartments are located back to back these side plates may be reversed when the operating-faces of said side plates become worn, so thatfinner abutting faces, which are perfectly straight and smooth, may be made the operating-faces, thereby saving much time and expense, which would be required to plane them down in the manner customary in the art.
In order that brick-machines may be used for the purpose of making bricks or tiles of different sizes and shapes, it is necessary that the mold should be constructed in such a manner that it may be readily changed or altered to `correspond with the brick it is intended to produce. With myimproved mold it will be observed that bricks of any size within the limits of the adjustments can be made by simply inserting the proper sides and ends for the compartments, and if dies are provided in the mold or on the plungers an ornamental brick may be made of any size desired. It is obvious that the size of the compartments can be enlarged or decreased, as desired, and in view of the fact that these compartments are adjustable laterally and longitudinally of the mold-table they can be readily disposed in their proper position relative to the plungers. As the compartments are built up side -by side and against each other and are adjustable simultaneously, the proper positions of the compartments with relation to each other will always be maintained.
- with the spacing-plates.
Independent adjustments of each compartment are therefore unnecessary.
With this construction, whether a single or multiple mold is used, the spacing-plates will absolutely limit the movements of the sides and ends of the mold toward each other, and the stopping of the movement of the sides will not prevent the' continued movement of the ends, nor will the stopping of the movement of the ends toward each other prevent the continued movement of the sides toward each other until the movement of allot' the plates is stopped and limited by engagement In other words, referring to Fig. 1 of the drawings, oneoi':1 each of the intermediate pairs of spacing-plates l) might be removed and the space occupied thereby could be `taken up without adjusting or changing the distance between the sides a a. So, also, all of the plates b might be removed and substituted by either larger or shorter plates without any change whatever in the position of the ends D of the mold. All of this would be equally true if the mold were but a single-compartment mold, for the mold can be made wider or narrower by the use of longer or shorter transverse spacingplates without any change whatever in the length of the mold, or the lengthot' the mold might `be increased or decreased without any change whatever in the width of the mold. So, also, both the length and 4breadth of the mold, by the use of the proper spacing-plates,
may be changed indefinitely between the maximum and minimum lsizes it is possible to produce. All this comes about by the adjustability of the sides and the independent adj ustability of the end blocks,wl1ich enables the mold to assume any dimensions fixed by the spacing-plates used, and no matter what change in the spacing-plates (which determines the length and breadth ot the mold) is made the mold will always look up tight in any adjusted position, locking one set of spacing-plates just as firmly as the other.
I am aware that changes in the form and proportion of parts and in the details of construction of myinvention maybe made without departing from the spirit and without sacriticing the advantages thereof, and I therefore reserve the right to make all such changes as fairly fall within the spirit and scope of my invention.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
