To all whom, it may con/06771,: Y
Be it known that I, WILLIAM S. JACKSON, a citizen of the United States, residing at Veedersburg, in the county of Fountain and State of Indiana, have invented new and useful Improvements in Mold-Supports, of which the following is a specification. y
This invention relates to moldsupports such as are used particularly in supporting molds or forms for sewers, concrete arches, and the like.
The objects of the invention are to improve and simplify the construction of such devices; furthermore, to increase their efficiency in operation and to decrease 'the expense attending their manufacture.
IVith the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the arrangement of parts and the details of construction v hereinafter described and claimed as a practical embodiment thereof.
In the accompanying drawings, forming part of this specification, Figure l is a transverse section through a sewer or concrete arch, illustrating a convenient method of employing the improved mold-support of this invention. Fig. 2 is a longitudinal section through the structure illustrated in Fig. l. Fig. 3 is a detail perspective View of one of the brackets. v
The reference character a indicates a body of cement or other suitable material, which is supported in the form of an arch by means of a suitable mold or form. The mold or form may be of any suitable form and construction. In the structure illustrated in the drawings the form comprises a plurality of planks a', such as are usually employed in forming structures of this character.
The improvements of the present invention relate particularly to the means for supporting the mold, which is formed by the planks a. To this end the invention comprises a pair of brackets A B. As shown in Fig. 3, each of the brackets preferably is formed with a mold-supporting member l, which is shaped to conform to the character of mold employed. In the embodiment of invention illustrated in the drawings a semicircular mold is employed. For this reason the moldsupporting member l of each bracket is shaped on the quarter of a circle. In addition to the mold-supporting member 1 each of the brackets also comprises what I shall for convenience term a common member 2. Diverging from the common member 2 on an angle slightly greater than a right angle is a pair of arms 3 4, which are connected at their separated ends with the mold-supporting member l. The arm 3 is formed with a laterally-odset portion 5 adjacent to the mold-supporting member l for a purpose hereinafter to be described. Arranged between the arms 3 and 4 is a plurality of intermediate arms 6 7,
which diverge from the common member 2 to the moldsupporting member l, as shown clearly in Fig'. 3.
In forming an arch or sewer according to the present invention the improved mold-supporting brackets are used in pairs, as illustrated in Figs. l andf 2, the laterally-offset portions 5 of the two brackets being arranged adjacent to each other. Means are employed for separating the upper ends of the two brackets. W'hile any suitable meanssuch, for example, as a wedge or block-may be used for this purpose, it is preferred to use a turnbuckle having' saddle members 8 and 8, which straddle the laterally-offset portions 5 of the brackets A and B, as shown in Fig. 1. By manipulating the turnbuckle in the proper manner it will be apparent that the brackets will be forced into the proper position to support the mold, which is formed by the planks a'. In order that the two brackets may be easily removed when necessary, it is preferable to support the common member 2 of each bracket upon a block 9, which may rest upon the ground or upon a suitable support 10, resting at its ends upon thickened planks af', arranged at the bottom of the mold. The blocks 9 may be easily knocked away in order to permit the removal of the brackets.
The construction of the improved mold-support of this invention is such that by loosening the separating' device C after the cement a has become suiiiciently hard the brackets A and B can be readily removed to permit the removal of the mold, which is formed by the planks a@ Changes in the precise embodiment of invention illustrated and described may be made within the scope of the following claims without departingfrom the spirit of the invention or sacrificing any of its advantages.
Having thus described the invention, what is claimed as new isll. A mold-support comprising a bracket having a mold-supporting member shaped on TOO IOS
IIO
aquarter of a circle, a common member, a pair of arms diverging from said common member to said supporting member on an angle slightly greater than a right angle, one of said arms having a laterally-oiset portion adjacent to the mold-supporting member, and intermediate arms diverging from the common member to the mold-supporting member.
2. A moldsupport comprising a pair of brackets each having a mold-supporting mem-l ber, a common mem ber and a pair of arms diverging from said common member to said mold-sup porting member, and adjustable separating means disposed between said brackets.
3. A moldsupport comprising a pair of brackets each having a mold-supporting member, a common member, a pair of arms diverging from said common member to said moldsupporting member, one of said arms having a laterally-offset portion adjacent to the moldsupporting member and a separating device contacting with the laterally-oiset portions of the two brackets.
4. A mold-support comprising a pair of brackets each having a mold-supporting member shaped on a quarter of a circle, a common member, a pair of arms diverging from said common member to said mold supporting member on an angle slightly greater than a right angle, one of said arms having a laterally-offset portion adjacent to the mold-supporting member, and intermediate arms divergingfrom the common member to the moldsupporting member, and a turnbuckle having saddled members contacting with the laterallyoffset portions of the two brackets.
In testimony whereofl I aiX my signature in presence of two witnesses.
