- MEANS FOR FIXING- ANCl-IOR-AG-ES IN CONCRETE WALLS.
Application filed May 13, 1914. Serial'No. 838,320.
To (all whom it may concern:
Be it known that we, JAMEs LEO MURPHY and JULIAN RICHMOND, the former a citizen of the United States, and a resident of the city of New York, in the county and State of New York, and the latter a citizen of the United States, and a resident of the city of Yonkers, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Means for Fixing Anchorages in Concrete Walls, whereof the following is a specification."
This invention relates to an article of manufacture designed for use in the fixing of anchorages or inserts in walls composed of concrete, plaster and the like.
Figure 1 of the accompanying drawings represents a perspective view of one embodiment of this device in position of use, showing the parts in their relative positions attached to a fragment of a mold preparatory to the molding of the concrete around them.
Fig. 2 represents a vertical section thereof.
after the concrete is cast around it. Fig. 3 represents a vertical sectlon of another form of embodiment of the invention with the concrete cast around it.
Similar reference characters indicate corresponding parts throughout the figures of the drawing.
This device constitutes an article of manufacture comprising a headed bolt 10 having a spiral rib or thread 11 preferably disposed in widely separated turns, a helical strip 12 carried on the thread of said bolt and de signed to be anchored as an insert in a con crete wall, and a holding plate 21 having a guide hole 25 for receiving said bolt and provided with means of attachment to a wall 20 of a mold. The bolt 10 is provided with a cylindrical enlargement 26 and an upset head 27.
A holding plate 21 has an opening 25 through which the party 26 of the bolt 10 freely passes when disengaged from the insert. The plate 21 is provided with a circumferential flange 23, which at its edge has a bent-over portion or bead 24, as shown in Fig. 2; the bead is provided to give rigidity against deformation. The flange 23 is of a depth substantially equal to the thickness of the upset head 27 of the bolt so as to form a recess in the concrete around said head to permit the easy removal of the bolt after the The plate 21 is provided Specification of LettersPatent.
lPatented Uct. 26, 1.915.
at its top with openings 30 through which nails or equivalent fastenings 29 pass, which have their heads 31 exposed at the upper part of the plate 21, and which nails extend into the wooden or other form 20 and thereby serve to hold the plate 21 in position, and at the same time hold the bolt 10 in position, When the bolt 10 is so held in position by the holding plate 21, the insert 12 is again placed on the bolt 10 and the concrete 15 is cast in the form, around the insert and bolt and holding plate 21, and when it solidifies the insert is found securely cast within the concrete at some distance from the face thereof. Thereupon the form 20 is removed as hitherto, but in so removing the form the nails become disengaged therefrom, so that when the form 20 is removed the bolt 10 engaging the insert 12, the plate 21, and the nails 29 all remain in position in the concrete. Thereupon the bolt 10 is turned and disengaged from the insert, and the plate 21 and nails are removed from the concrete depression, leaving only the concrete depression 36 and an opening 37 corresponding to the shape of the bolt. The belt 10 may be replaced in the insert by screwing the same therein, whenever desired, for the purpose of attaching articles. It will be noticed that by reason of the cup-shaped plate 21 keeping the concrete during casting and setting out of contact with the bolt-head 27, the bolthead remains free from any concrete which would prevent its removal, whereby after the concrete is set the bolt can be readily grasped by a wrench or the like and readily removed.
In the embodiment shown in Fig. 3, the insert 45, bolt 44, screw-threads 43, and concrete body 46 are substantially like the corresponding parts shown in Figs. 1 and 2; but, instead of a cup-shaped holding plate 21, a flat holding plate 47 is employed, which has an opening 49 through which the bolt 44, with its enlarged portion 42, can readily pass. The form 20 is in this case provided with a cut-out portion or recess 40 substantially equal in depth to the thickness of the bolt-head 41, as shown in Fig. 3. The plate 47 is provided with openings for permitting nails 48 to pass therethrough to fasten the plate 47 to the form 20. The plate 47 serves to hold the bolt 44, with its insert 45, in position during the solidification of the concrete, and also keeps the concrete away from the head of the bolt so as to enable convenient removal of the bolt. In a similar manner, as n the operation described In connectlon with the embodlment shown 1n Flg,
2, the form is removed, leaving the nails plified means of attaching and accurately locating the inserts in predetermined posiremoval'of the forms. crete would haveito be broken away at great tions in the form, where they may be later employed for the ready attachment of fixtures or other objects to the solidified substance, after the forms have been removed,
is provided.
' The holding plates may be made ofsuch size and shape, by varying their configuration, as to fit a given fixture or object or 7 part thereof and permit countersinking of the fixture, object, or partthereof in the concrete at the point where it is desired to afiix said fixture or object to the solidified concrete.
Where it is not desired to have a depression in the concrete, the fiat'form of holding plates may be used. In any case, the plate may be properly attached to the form by nails, prongs on the plate or any of the well known methods suitable for attaching.
It will also be seen that the main objects of the holding plate are, first, to provide a channel or path for transmitting to the bolt the force which holds the plate to the form,
and thus holds the bolt in its desired posie tion; and, secondly, to provide a guard to prevent the fluid concrete from completely enveloping the bolt so that it is impossible to remove it from the solidified concrete for the purpose of attaching a fixture, after the Otherwise the coninconvenience, disfigurement and expense, so that a wrench or other tool could engage the bolt and turn it out of the concrete.
' A further advantage is to enable two or more bolts as a unitto be accurately placed so as to conform to the bolt-holes in a given fixture.
A further advantage is the desirability of locating bolts and inserts Wherethey Will be of use later, and doing away with the expense, inconvenience, dirt and danger to the strength of the structure from drilling holes in the solidified concrete.
further advantage is that the inserts may be located at any distance back from the surface, thereby giving the desired degree of strength against dislodgement from the solidified concrete.
As the bolts may be placed in position without the necessity of drilling holes completely through the forms, destruction of the forms, and the attendant expense, dirt and inconvenience, are thereby avoided. Instead of Wooden forms, metal forms may be used and suitable means provided for securing the holding plates in position thereon. So, the invention may find its application to other forms as well used in the casting of concrete.
A further advantage is that the holding plate may be accurately located and oriented by means of suitable marks thereof, thereby locating the inserts in the correct position in the form.
I'Ve have shown several embodiments of our invention, but it is clear that changes may be made therein without departing from the spirit of the invention as defined in the appended claims.
I e claim:
1. An article of manufacture comprising a headed bolt, a spiral strip carried on the threads of said bolt and designed to be anchored as an insert in a concrete wall, and a holding plate provided with a guide hole through which the shank of said bolt is passed and with means for securing said bolt to the bottom or wall of a mold.
2. An article of manufacture comprising a headed bolt, a spiral strip carried on the threads of said bolt and designed to be anchored as an insert in a concrete wall, and a holding plate provided with a guide hole through which the shank of said bolt is passed and with means for securing said bolt to the bottom or wall of a mold, said holding plate having a recess adapted to inclose and permit the turning of the head of said bolt.
In testimony, that we claim the foregoing as our invention, we have signed our names in presence of two subscribing witnesses.
