JOSEPH W. HOLMAN, OF CLEVELAND, OHIO.
MOLD FOR SIDEWALK CONSTRUCTION.
To all whom it may concern:
Be it known that I, JOSEPH W. HoLMAN, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Molds for Sidewalk Construction, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle. so as to distinguish it from other inventions.
My invention relates to a simple mold construction for use in forming sidewalks, in which are set lights of glass, such as are used over cellars extending into the street.
Various types of construction have been used for the purpose of forming the concrete molds around the lights of glass, but serious difficulties have been met with in the use of each type. It is possible to form a very firm and lasting sidewalk by the use of metal molds which, however, must be left in the sidewalk after completion, thus necessitating a considerable expense for materials at every sidewalk laying. Another type of mold in considerable use allows the with drawalof the molds after the laying of the sidewalk, but necessitates the placing of the reinforcing rods in such a position relative to the lights of glass that leakage is almost sure to result.
With the present construction it is possible to form a very secure sidewalk and to place all of the reinforcing members or tie rods below the level of the lights of glass, which is a very advantageous construction for this purpose.
To the accomplishment of these and related ends, said invention, then, consists of the means hereinafter fullv described and particularly pointed out in the claims.
The annexed drawing and the following description set forth in detail certain mechanism embodying my invention, such disclosed means constituting, however, but one of the various mechanical forms in which the principle of the invention may be used.
In said annexed drawing :-Figure 1 is a view in perspective of a sidewalk which has been formed with my molds and which is shown attached to the wall of the building and the side wall of the cellar; Fig. 2 is a section, taken through a sidewalk of this type, parallel to the wall of the building;
Specification of Letters Patent.
Application filed February 3, 1912.
Patented Dec. 9, 1913.
Serial No. 675,337.
Fig. 3 is a side view of one of the molds; Fig. 4 is a side view of the mold showing the supporting member attached thereto; Fig. 5 is a front elevation of the supporting member, and Fig. 6 is an end elevation of the same; Fig. 7 is a view in perspective of two of my mold members when in operating position; Fig. 8 is a section taken at rightangles to the line of section of Fig. 2, showing a mold in position and also the supporting member and the external supporting means.
From Fig. 1 the general construction of a sidewalk formed by means of my molds will be readily apparent. A heavy reinforced concrete rib 1 is shown attached to the front of the building, and from this run the deep ribs 2 at right angles to the same. Another reinforced rib 3 will be used at the side of the sidewalk adjacent to the side of the cellar. It will be noticed that the alternate ribs 2 are heavy and the intermediate ribs 4 are of light construction. Transversely disposed ribs 5 are shown, and between these transversely disposed ribs and the longitudinal ribs 2 and 4 are placed the lights of glass 6.
In Fig. 2 the general construction of my molds is shown. A series of pairs of molds will be used, each pair comprising two complementary molds 7 and 8, which are provided with laterally extending flanges 9 on the adjacent faces of the same, and with other laterally extending flanges 10 on the opposite sides of the same. The first named flanges are near the top of the mold member, and the flanges 10 will be at or near the bottom of the same. The molds are laid down adjacent and parallel to each other with the flanges 9 in contact, as shown in Fig. 2, when they will be engaged by a supporting member 11 which has an inwardly projecting lug 12 adapted to engage the under side of the flanges 9, and a base flange 13, upon which are mounted suitably formed lugs 14, which will engage the recesses 15 in the bottom of the mold members. In this Way, the two complementary mold members will be supported at either end by a single supporting member, which will itself be supported from any suitable external means. The external means which will be provided may consist of two members 20, which will be held upon supports 21 at either end, resting upon the ground. It will be understood that these supports just referred to, are merely a scaffold which will be temporary and will be no part of the building after completed. By reason of the disposition of the flanges 9 and 10 upon the mold members, it will be seen that alternately deep and shallow ribs will be formed. After the concrete has been poured in around the mold a suitable drawing member (not shown) having a projecting lug on it will be attached from the under side to a lug 16 on the front of the support ing member, the two lugs engaging, as will be readily understood. A downward pull on the same will then withdraw the supporting member from its engagement with the mold member. The latter can be similarly withdrawn from engagement with the concrete itself by using the same member which will be attached to the apertures 17 in the mold members. It will be obviously a matter of indifference as to whether the supporting member projects below the mold member when in engagement, as shown in Fig. 4, or not, as the latter can be suitably supported by a very slight change in the form of the lug 14, without the necessity for the supporting member hanging below the same. The drawing member is not in itself an essential part of my invention, and any suitable means for this purpose may be provided. In actual practice the mold members may be of any suitable length, but will most readily adapt themselves to this use if made of a length suflicient to enable them to extend from side to side of the space to be covered. They may, however, comprise a member such as is shown in Fig. 3, in which case the mold will have space for but three lights of glass instead of any desired number, as is possible when the molds are designed to extend fully across the space to be covered.
From the foregoing description the general construction of the molds will be evident. Each mold is substantially rectangular in plan, having a flange on each of its long sides. It also has transverse troughs or grooves 18 at equal intervals, thus forming the mold into square areas. Within these areas the mold is cut away, permitting the engagement of a light of glass 6 therein. Each light of glass is provided with flanges 19 for a purpose which will be hereinafter described.
After the mold members have been attached to the supporting members and are parallel and in contact with each other, reinforcing members 20 will be placed in the various troughs formed between the molds and across the same, and the lights of glass, which will preferably be of the form shown in dotted lines in Fig. 2, will be inserted in the apertures which are provided by cutting away the upper side of the molds.
The
In Fig. 7 I show a view in perspective, of two of my mold members which are together in the position shown in Fig. 2. It will be seen that each of these members has ribs running longitudinally of the same, and other transversely disposed ribs, thus cutting the mold up into a number of squares, in which, or upon which, the glass will be inserted. As here shown, the molds are cut away in these sections for the sake of lightness and eheapness, but it will be understood that this is not necessary except where the lights of glass have projecting flanges and part of the body depending below these flanges.
Fig. 8 shows a longitudinal section of a sidewalk, and the molds forming the same, and shows also the supporting members in position. I/Vhen it is time to draw the mold, the supports 20 and 21 will be removed, when the members 11, and the mold members will be retained in their positions only by the adherence of the concrete. The next step will be to remove the members 11, by the means already described, which will leave a triangular space between each end .of the mold members and the adjacent concrete wall. It is impossible, or practically so, to draw a mold evenly, and it is there fore necessary to draw downwardly on one end, letting the other end pivot, as is shown in dotted lines in Fig. 8. It will be noticed that my construction adapts itself readily to this method of procedure, as by reason of the triangular space between the mold and the concrete, it is possible for the lower right-hand end of the mold to swing to the right, pivoting about the upper right-hand corner of the mold. In this way the concrete ribs which have been formed by the troughs in the mold, are not injured by the drawing of the mold, as the latter swings freely away from these ribs.
Simplicity of construction and convenience of operation are two of the more important advantages secured by the use of my improved molds. Other advantages are the strength of the sidewalk made by the molds and the comparatively low cost of the same, since the molds can be used over and over again.
Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
I therefore particularly point out and distinctly claim as my invention 1. In mold construction, the combination of two complementary molds disposed adjacent and parallel to each other, each of said molds having a laterally projecting flange on the side adjacent said other mold, said flanges being adapted to contact throughout the length of the molds, thereby forming a trough, and a supporting member disposed at either end of said molds and adapted to removably engage, and support said molds.
2. In mold construction, the combination of a plurality of complementary molds, disposed adjacent and parallel to each other, each pair of said molds having laterally projecting complementary flanges a short distance below the top on the adjacent faces of the same, and other laterally projecting flanges on the exterior faces of the same, said other flanges being a greater distance from the top than said first-named flanges and being adapted to contact similarly formed and disposed flanges on the exterior faces of the adjacent molds, and a supporting member adapted to remo 'ably engage the ends of each pair of complementary molds, thereby supporting the same.
3. In a mold construction, the combination of two complementary molds disposed adjacent and parallel to one another, each of said molds having a plurality of transversely disposed troughs adapted to register with the troughs of said other mold, laterally pro jecting flanges on the adjacent faces of said molds, said flanges being adapted to contact throughout the length of said molds, thereby forming a second trough, and a supporting member adapted to removably engage the ends of each pair of complementary m lds, thereby supporting the same.
4. In a mold construction for forming side Walks, the combination of a series of molds disposed adjacent to each other, each of said molds having a plurality of transversely disposed troughs adapted to register with the troughs of the other molds, and laterally projecting flanges on the adjacent faces of said molds adapted to contact throughout the length of said molds, thereby forming other troughs, each of said molds having apertures between said transverse troughs adapted to receive a light of glass, said glass extending slightly over the edges of said mold into said troughs.
5. A mold member for sidewalk construe tion, comprising a rectangular mold member having a laterally projecting flange on either side thereof, such flanges being at unequal heights on such sides, said mold member having transversely disposed troughs at equal intervals throughout its length.
6. A mold member for sidewalk construction, comprising a rectangular mold having a laterally projecting flange on either side thereof, such flanges being at unequal heights on such sides, said mold having transversely disposed troughs at equal intervals throughout its length, and having also rectangular apertures between said transverse troughs.
