INVENTOR ATTORNEY JOHN EDWARD OGDEN, OF CORNWALL, NEW YORK..
ADJUSTABLE CONCRETE-INSERT.
Specification of Letters Patent.
Patented Jan. 18, 1921.
Application filed June 28, 1919. Serial N0. 307,398.
To all whom it may concern:
Be it known that I, JOHN EDWARD OGDEN, a citizen of the United States of America, and a resident of Mountainville, town of Cornwall, Orange county, and State of New York, have invented certain new and useful Improvements in Adjustable Concrete-Inserts, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
This invention relates to concrete inserts which are adapted to be embodied in concrete slabs of different thicknesses by means of which inserts bolts or screws may be affixed to the finished structure, and its object is to provide a simple and inexpensive device for this purpose. More specifically, its object is to provide an adjustable device of this character which is especially adaptable for use in slabs of different thicknesses. These and other objects of the invention will appear in the following specification, in which I will describe the invention and the novel features of which will be set forth in appended claims.
Referring to the drawings:
Figure 1 is a sectional elevation of a device which is made according to and embodies this invention. In this figure, a molding board is shown together with a part of a concrete structure, both of the latter parts being also shown in section.
Fig. 2 is a sectional plan view of the same device, the section of this figure being taken on the line 22 of Fig. 1.
Fig. 3 is a sectional elevation of the device shown in the preceding figures with the parts thereof shown in different relative positions. In this-figure a part of the molding board is shown together with a device for easily centering the insert.
Fig. 4 is an elevation of a modified form of construction which also embodies this invention. In this figure certain parts are broken away to more clearly illustrate their construction- Fig. 5 is an elevation partly in section of another modified form of construction.
Fig. 6 is an elevation of a still further modification.
Like characters of reference designate corresponding parts in all the drawings.
10 designates a molding board upon which a concrete body'is to be formed, in this particular case a floor slab, a part of which is shown at 11.
12 is a cylindrical member preferably pressed out of sheet metal. The upper end of this member is closed as at 13, and at its other end the metal is bent outwardly to form flanges 14 with stiffened ribs 15 formed between the body of the device and the flanges. In the flanges are formed indentations or notches 16. The lower portion of this member has a smooth cylindrical wall 17 but the upper portion of it is crimped or corrugated to form screw threads 18 on both the inside and outside of the tube.
20 1s an open ended cylindrical member with its walls crimped or corrugated through the length thereof to form screw threads which fit the threads 18 on the outside of the member 12. This member 20 also has an outwardly projecting flange 21 at its lower edge. f
In Fig. 3 a tapered plug 19 is shown removably aflixed to the molding board 10.
Before specifically describing the devices shown in the other figures of the drawings,
I will describe the way in which. this device is used. Before a concrete floor, for example, is made forms are prepared for the reception of the plastic concrete. The moldmg board 10 is a part of one of such forms. At such points as is desired to have screw sockets in the finished structure, inserts are placed. These may be ailixed to the molding board by tacks in the notches 16 as shown in Fig. 1, or may be positioned by being placed over the tapered plugs 19 which are first fastened to the board 10 at the desired'points, as shown in Fig. 3.
as it is desirable to have the length of the device varied and the flanges 14 and 21 separated difl'erent amounts in structures of differcnt thicknesses, the member 20 is turned on the member 12 to vary its position thereon.
In Figs. 1 and 3 the member 20 is shown in two of its positions, and it is obvious that it is adjustable through a great range. As shown in Fig. 1 the device is adjusted for use in a comparatively thick concrete slab. In this case the cylindrical threaded part above the member 20 extends above the closed upper end of the part 12. The result is that some of the concrete enters the space between the wall of member 20 and the top 13 of the member 12. This part is desig nated 11 and serves to hold the device in an upright position, and to strengthen its hold in the concrete.
in Fig. 3 the parts are in different relative positions as used in comparatively thin slabs.
Thus with this device it is not necessary to provide inserts of a plurality of lengths for different thicknesses of concrete but inserts of standard since may be readily adjusted to meet different conditions. the concrete has set and the molding l3Oi1 1O removed screws or bolts may be inse in the sockets formed by the inserts and their threads will engage the threads if) on the inside of the member 12. The threads on the outside had previously been used for the purpose oi adjusting the positi n o? member 20 on the member In the device shown in Fig. 4- the inner or lower flanged member 30 is seen at both ends. L is shown crimped or corrugated through its length to form screw threads on the inside and en the outside o the cylindrical wall. The outer or 11 member 31 closed at the top as at 3 crimped or corrugated throughout its length to form threads which it over the threads 30 on the outside or the lower member. it may be seen that i this case the distance between the flanges and the members and 31 may be maried by simply imparting; la tive rotation between these r embers. also obvious that the upper member may be made of smaller diameter than the lower member so as to screw inside the same in which case its flanged end will be uppermost as in the case of the upper member shown in Fig. 5. It is also clear that a screw or bolt may engage the threads inside or the member 30 after the concrete structure is finished.
Fig. 5 is an illustration of a device which comprises a cylindrical member i0 the outer surface of which is threaded near its ends and at least one end of which is also threaded on the inside, as at 11. Two similar flanged end pieces 42 and 43 are screwed onto the cylindrical member d si red amounts to vary the length 01": the assembled device and the distance between its flanges. ii. plug 44 is driven into the upper end of member 40 to prevent the entry of any concrete. A'ter the device is embedded in a concrete structure a bolt may be inserted in the threads 41.
The cylindrical member 12 in Fig. 6 is similar to that shown in Figs. 1 and 3, but in this case the part 50 is a flange of double thickness metal engaging the outer surface of member 12, and preferably threaded internally so that its position on the member 12 may be adjusted by rotating it.
[This invention is capable of many variaions and modifications, some of which. have been illustrated and described to show practical embodiments thereot and while most o l the structures shown are olf pressed metal, the invention. is not necessarily limited to devices r it this particular form or construction. I intend no limitations other than those i1nposed by the appended claims.
