JAMES ELLE'RY MARBLE, 0F ELZABETH, NEW {lRSllTtl CONCRETE-INSERT.
Specification of Letters Patent.
Patented July 6, 1915..
Application filed February 8, 1915. Serial No. 6,705.
-To all whom 'it may concern:
Be it known that l, JAMES E. MARBLE, a citizen of the United States of America, and a resident of Elizabeth, county of Union, and State of N ew Jersey, have invented certain new and useful Improvements in Concrete-Inserts, of which the following is a `floors, walls and the like, to facilitate the specication.
My invention relates to improvements in what are known as concrete inserts, viz:-'- devices intended to be set into concrete attachment of various articles, such for eX- ample as shaft-hangers, pipe supports, etc., to such floors and walls. lThese inserts are commonly objects of the general nature of a metal socket piece, provided with means whereby they may be rnily interlocked with the concrete, and with means whereby they" may be securedto the false work or centering used during the molding lof the concrete floor, wall, etc. However, former devices for this purpose have possessed numerous disadvantages which are overcome inthe structures for the same purpose herein illustrated and described. In particular, most former devices for the saine purpose have not been constrncted in such manner that they can be secured with suficient firm- .ness to the false work or centeri g, as a result of which former inserts are very frequently displaced, over-turned, a d consequently lost during the dumpig of the concrete mixture around them, an the leveling of the concrete; infact, it is not un-A usual in the erection of concrete buildings to lose more than half of the inserts in this manner. Again, as such inserts have been constructed in the past it has been diiiicult to locatel them accurately in their intended positions. The centers of these positions are 'usually marked on the false work; but the insert being an object of some size, the center mark is covered by the insert when placed, and there is nothing to show that the insert has been properly centered with reference to such center mark.
My invention comprises a novel concrete insert so constructed that it may be secured .very firmly to the false work, may be centered accurately and easily with reference to its intended position, and, when the concrete has set about it, is anchored very rmly 1n that concrete. .f Furthermore, my insert is s .O constructed as to permit a considerable lati- 1 tude of adiustment, with reference to the inview' similar to Fig. l, except that sert, of the bolt o rother member to be supported by. that insert.
The objects of my invention are, to improve securlng devices such as are commonly termed concrete inserts, to provide such a device which shall not be liable to displace- .ment, which may be centered readily and easily and which will be held very firmly by the concrete, and to provide a device possessing the above advantages and which is simple and easy to construct, relatively light, and inexpensive, strong, and which aords a wide range of adjustment of the device to supportedvwith reference to it. i I will new proceed to describe my invention with. reference to the accompanying dranfing features in claims. In said drawings: Figure l shows a longitudinal vertical section of one form of my improved concrete insert, setl within a body of concrete or the like; Fig.. 2 shows a vertical transverse section of the same device lso set; Fig. 3 shows a front elevation of the said insert; Fig. 4 shows a side elevation thereof. Fig. b is a the means 'for hold g .the insert in place during the placing i setting of the concrete 's indicated. w. 6 shows a top view of. vhe insert. Fig. shows a sectional perspective of the insert with a T-headed bolt shown in place therein. Fig. 8 shows a transverse vertical section of one form of the bridge piece which l commonly use in connection with the insert, in holding that insert infplace duringy the laying of the concrete, and also,
. and will then point out the novel in some instances, for the support 'of objects by the insert after thevconc'retehas set. Fi g. 9 shows a vertical transverse section of an alternative form of the insert. Fig. l0 shows a vertical longitudinal section 'of such alternative form. Fig. ll shows a horizontal section of such alternative form, the section be-` ing takenV on the line -:v of Fig. 10. Fig. l2 is a view similar to Fig. 5, though on'a smaller scale, but illustrating the use of a wood screw instead of a bolt for holding;
the insert toy the false work.
Referring first to Figs. l-8 inclusive: Numeral l designates the insert itself, the same being a hollow box-like body having a top 2 and having at its ends extensions 3 provided with enlarged tops 4, whereby the device ,is 'anchored in the concrete.` For further4 anchoring of the insert within the concrete, such insert is preferably provided i f drop abolt 11 down tering that such insert by the concrete.

ln locating this insert l commonly bore a small hole through the centering or false Work at the -place marked thereon forv the center of the insert, 'Within the insert a bridge piece, such as the bridge piece 8 of Figs. 1 'and 2, or the nearly similar bridge rpiece 8a shown (suoli bridge piece being so vplaced that it is supported atthe ends by the ledges 7), l through the hole in the top 2 of the insert, and through the central I hole of the bridge piece 8 or 8? and through the hole so bored in the centering, and then apply a nut 12 to the bolt and, by screwing in lt is easy to center the insert, with almost absolute accuracy, with reference. to the head or this bolt, by the unaided' eye; for the head up that'bolt, l fasten the insert firmly of the bolt will be but little smallerthan the hole in the top 2 oft the insert,'and it is easy for even an unskilled vvorlrinan to determine Whetlier the hole in the top 9; oi" the insert is substantially central with reference to the head oit this bolt. @t course such centering of the insert with reference to the bolt. head is done before the nut 12 is screwed up tight. @nce that nut has been'screvved up tight, the insert is4 held sov irrnly to the cenvvill not be displaced "Workmen, during the laying'of the 'lhe insert can even be struckv violently Without being displaced, when so secured in place; for in order todisplace that insert, once the nut .has been screwed up,

Ur, instead ot a bolt suchl as 13 screwing into a threaded. bridge piece 8, l may employ a bolt such as the bolt 9 shown lmhead 15 vand having, preferably, iiat shouldeis 16 beneath its head, suoli shoulders adapted to engage the sides of the slot G and thereby to prevent turning ot' the bolt` lt will be understood that sufficient clearance nrovided between the tops of the ledges the top' 53 of the insert, to permit the insertion of the head ot the bolt with its head 15 the slot, and then to permit thebo t at right angles to the vslot and. dropped so that its shoulders lengage the sides of the slot 6, as'indicated in Fig. 7; and it Will be understood that. the bridge piece 8 may be inserted in similar manner. lNhen a threaded bridge `piece 8, to coact subsequently with a bolt such as bolt 13, is used, this bridge'piece may also be the bridge piece used for holding the insert in place during the laying of the concrete; but ivlien a lm-headed bolt is simpler and cheaper bridge piece 8, shown in 8, is ce" e tasten- 8 being removed alter the false Work has been removed. ln seine cases, instead et boring through the talee Work and using e l holding the insert in 'All use an ordinary Wood sore u, 1"?

InFig. .7 the hole in the top 2 of the insert is shown as square; but inmany cases this hole is round, as indicated by the shading ofthe plug in Figs. l and 2.
It will be understood that this insert permits considerable lateral adjustment of 4thel bolt 13 or 9, with-reference to the insert, and the bridge .piece 8 maybe moved to any desired position from one end of the slot 6 to the other end thereof. Most ofthe in-g se'rts heretofore used, andin which provision for such lateral adjustment'is made,
have been provided with what is known as a l keyhole slot, 2'.. e., a slot which is much zol wider at one end than at the other; suchv .wider portion of the slot being provided in order to permit the insertion of the head of a boltoi' the like; as a. result, relatively vsmall latitude for lateral adjustment of the position of the bolt is permitted in such `former devices. and obviously thel bolt is not -supported when its head is'in the larger portion of the slot; but my construction provides full support for the bolt, or. bridge piece S, from one end of the slot .to the other. Moreover. the webs of metal form- 'ing the ledges 7 have support not only from the sides of the insert, but also from the ends of the insert, and for that reason these-webs of metal are muchvstronger, for equal dimensions and equal quality Otmaterial, than is the case when a keyhole slot.
is provided.
Preferably my insert is a malleable iron casting ora steel casting, and therefore its extensions 3 may 'have such iexibility that, ifv desired,they can be bent over as indicated in dotted lines in Fig. l; thus providing additional anchoring in the concrete; and the extensions 3 -maybe lbent over in this manner either before the insert has been. placed upon the false work, or afterward. l
ln "some cases itis desirable to locate inserts in sloping walls or ceilings, such inserts to support objects located directly beneath the bottoms of the inserts. In such cases, the form of insert shown in Figs. 9, l0 and ll is convenient. In this formi-the insert is provided at its bottom with a slot 6, as in the construction shown'in Fig. 2, but' the ledges '7a at the sidesof ythis slot are each provided, at aboutjtheir centers, with a semi-'circular recess to receive `a T-h'eaded bolt 9a having its lower side cylindrically 'alined over curved. It will be clear that ythe insert shown in Figs. 9, 10 and 1l can be set at an angle from the vertical, and yet the bolt 9a will hang vertically.
That I claim is l. An insertv for concrete vand similar structures comprising a hollow-body adapted to kbe attached to forms or concrete andv having integral side and top walls pro- -vided with means for engagement with the concrete, said body having an elongated slot in its bottom for the reception of supporting ldevices and of attaching means for attaching said body to said forms, the top of said body having a centrally arranged opening, whereby the' center of the opening can be any desired point of the form.. -V
2. An insert for concrete and similar structures comprising a hollow bodyl adapted to be attached to forms for concrete and' having integral side and top walls provided with means for engagement vwith the `concrete, said body having'an elongated, slotl in its bottom for the reception of vsupporting devices and of attaching means for attaching said body to said forms, the top of said body having a centrally arrangedL opening, whereby thecenter of the opening can be alined over any desired point ofthe form, and a plug of eXpansible material closing said opening to prevent inflow of lliquid concrete into said body.
3.. An insert for concrete and similar structures comprising a hollow body adapted to be attachedto .forms for concrete andv having integral side and-.top walls provided with meansffor engagementwithv the concrete, said body' having an elongated'slot in its bottom for the reception of supporting devices and-of attachingmean's for attaching said body t'osaid forms, and ledges on both sides of said slot'. extending from one end to the other of the body, the top of. said body having a .centrally arranged opening closed by a wooden plug, a bridge-piece within the body portion resting on said ledges and slidabletherealong and having a threaded opening throughout its length, and a screw' threaded member extending through said threaded opening into said body and into engagement with said wooden plug, whereby the loosening of said screw threaded Vmember is prevented.
In testimony whereof I have signed'this specification inthe presenceofv'twosubscribing witnesses.
