MOLD FOR MAKING GONGBETE ARTICLES.
Apnlication filed October 2, 1917. Serial No. 194,390.
To all whom it may COTZOGTTLJ Be it known thatI, CHARLES F. BUnN'rn, a citizen of the United States, residing at Avalon, Allegheny County, Pennsylvania, have invented a new and useful Improvement in Molds for Making Concrete Articles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which:
Figure 1 is a side elevation partially in section of one formof my improved method.
Figure 2 is a plan view partially in section of the mold shown in Figure 1.
Figure 3 is a plan view partially in section of a portion of a table and a series of molds of a modified form.
Figure 4c is a side elevation of one of the moldsshown in'Figure 3, and
Figure 5 is a vertical section on the line VV of Figure 3, of the mold shown in Figure 4:. a
This invention relates to an improvement in molds for making concrete articles, and 25 is adapted to be used in connection with the method and apparatus for making concrete articles disclosed in my application, Serial No. 194,391, filed October 2, 1917, although it is adaptable to be used in connection with so other methods and apparatus than that shown in this case.
The object ofmy invention is to make an inexpensive and efficient mold built up of a plurality of enclosing members of hollow form, through-which a heating medium is circulated, and in which the connections are so arranged that one of the members can he moved relative to the other without breaking the circulating connections. Another object of my invention is to provide a mold of this character in which the closing and opening members are connected to the mold sections, and which are so arranged that the sections can readily be separated for the removal of the finished article.
The molds, shown and described in this application, are also adapted to be used in connection with the sectional cores shown and described in my co-pending application,
Serial No. 194,389, filed October 2, 1917.
The precise nature of -my invention will be best understood by reference to the accompanying drawings, which will now be described, it being premised, however, that various changes may be made in the detail of construction and the general arrangement of the parts, without departing from the spirit and scope of my invention, as defined in the appended claims.
Referring to the structure shown in Figure 1, the reference character 2 designates a base plate or palette, which may be in the form of a rotary table such as shown in my application, Serial No. 194,391. Supported on this table 2 is a centering member 3 for centering the mold sections 4; with relation to the table 2. 5 is a collapsible core which may be of any suitable type or may be of the form shown in my application, Serial No. 194,389 filed Oct. 2, 1917.
In this construction the mold comprises four hollow sections t which are pivotally connected to each other in such a manner that all of said sections can be moved relative to their adjacent sections. Each section 1 is provided with a plurality of sets of lugs 6 at one end thereof, and pivotally connected to each set of lugs, by means of a pin 7, is a link 8, there being two links in alignment with each other, connected to one end of each of the sections. The other ends of each pair of links are connected to cranks 9 on a crank shaft 10, which is pivoted in bearings 11 on the other ends of the mold sections, the arrangement being such that when the crank shafts are moved, the ends of the two sections of the mold will be moved relative to each other. 1
Each mold section is provided with a hollow space or spaces 12 between the inner and outer walls thereof, and connected to the top of each of these sections is an inlet pipe 13 which is connected by means of a flexible connector 1 1 with a main supply pipe 15. 16 is a main outlet pipe which is connected to each of the outlet pipes 17 0f the various sections by means of a flexible connection 18.
The mold is filled in any desired manner, or in the manner described in my application, Serial No. 194,391, and after the mold has been filled, steam or hot water is circulated through the various sections to partially seat the concrete in the mold. When it is desired to remove the article from the mold, the cranks 9 are rocked approximately to throw the mold sections away from the molded article as shown in the upper portion of Figure 2. The arrangement is such that each section of the mold can swing 11c about the pivots of the locking members at both ends, to move the sections away from the molded article.
In Figures 3, 4 and 5 I have shown a modified form in which I have used the same reference characters with the letter a aflixed. In this construction there are a plurality of smaller mold sections supported on the bed or table 2 each comprising two sections a, which are arranged to swing about the centers 19 when they are opened, by means of the crank shafts 10 In the foregoing description and in the drawings I have merely described and shown a mold for making pipes, but it will readily be understood by those familiar with the art that this type of mold is adaptable for various forms, in which it is desired to expand the mold sections when removing the mold from the formed article.
The advantages of my invention result from the provision of a concrete mold formed of a plurality of sections pivoted to each other, together with means fixedly connected to the sections for opening, closing and locking the sections in their closed positions. Also from the provision of molds made up of a plurality of hollow sections which are provided with flexible connections for circulating a heating medium through the sections, and which are so arranged that the sections can be moved relative to each other to open and close them without breaking the connections.
I claim:
1. A concrete mold having a plurality of separable sections, each section having a jacket, a support for the sections, a fluid inlet pipe mounted on the support, a fluid outlet pipe mounted on said support, a fluid inlet connection leading from each jacket to the fluid inlet pipe, there being a flexible connection included therein, and a flexible connection leading from the fluid outlet pipe to each of the sections, substantially as described.
2. A concrete mold comprising a plurality of pivotally connected sections, each section having a jacket, a flexible fluid inlet connection for the aeket in each section, a flexible fluid outlet connection from each acket, and means co-operating with the pivotal connection between each pair of the sections for moving the adjacent edges of the sections toward and from each other, said flexible connections permitting such movement, snh stantially as described.
3. A concrete mold, comprising a plurality of sections, each section being pivotally connected at its opposite edges to the two adjacent sections, and means co-operating with the pivotal connections between said sections for moving the adjacent edges thereof toward and from each other to move the mold sections uniformly and radially inwardly and outwardly, substantially as described.
4. A concrete mold, comprising a plurality of sections, each section being pivotally connected at its oposite edges to the two adjacent sections, each of said pivotal connec tions comprising a link and crank whereby the adjacent edges of the sections may be moved toward and from each other to uniformly move all of said sections inwardly and outwardly, substantially as described.
'5. A concrete mold having a plurality of similar sections, each section being pivoted to the adjacent sections at the opposite edges thereof, each pivotal connection being arranged to permit one section to pivot on the other, and also to move the two sections relative to each other, substantially as described.
6. A concrete mold having at least three sections pivotally connected to each other at the adjacent edges of the sections, each of the pivotal connections comprising a pivoted link and a crank, the arrangement being such that when the crank is in one position the adjacent mold sections will be unformly drawn toward each other and when in the other position will be uniformly moved radially and separated from each other, substantially as described.
In testimony whereof, I have hereunto set my hand.
CHAR-LES I. BUENTE.
