ANCHOBRSOCKET.

Specification of Letters Patent.

Patented June a into.

Application filed June 7, 1909. Serial No. 500,727.

To all whom 'it may concern:

Be it known that I, IRVING CowLEs, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Anchor-Sockets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a novel construction in a device adapted to be embedded in concrete or similar material, which is molded in plastic form and subsequently sets, for the purpose of providing sockets therein for the anchorage of fixtures of all kinds, the object bein to provide a simple and efiicient device of this character and consists in the features of construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings illustrating this invention: Figure l-' 18 a vertical transverse section of a device constructed in accordance with my invention showing the same embedded .in a concrete ceiling and having a bolt secured therein. Fig.'2- is a top plan view of the device. Fig. 3 is a, plan section of the same on the line 3-3 of Fig. --1. spcctive View of one of the two members constituting my device.

My invention'has for its object to provide a device for anchoring fixtures to concrete walls, ceilings, floors and the like, which is cheap, easily a plied and which furthermore will permit 0 the easy insertion of a lint adapted to receive the shank of a bolt and permit lateral play in one direction of said bolt in order to line up pipes, line shafting and the like, and which furthermore permits of the admission of a considerable length of shank of a bolt so as to enable the elevation of fixtures to be varied and adjusted to a considerable extent.

My said device comprises two identical members A preferably of cast iron or other suitable metal, said members A being each provided on their upper ends adjacent their op osed faces with male and female interloc ting devices B and C respectively, which when said members are opposed, oppose each other. The member B consists of a hook which is adapted to enter a slot in the member C when said members A are disposed at an angle of about ninety degrees to each Fig. -+lis a detail per-- other, and which when said members are turned parallel with each other so that their opposing faces contact with each other, to engage at its free end the rear face of the member C thus holding said members A against relative movement in all directions except pivotally. Each of said members A is substantially rectangular in vertical longitudinal section and is provided with paral e1 side walls D and a top wall E dis osed perpendicularly to said side walls and on which said male and female interlocking members B and G are disposed. Said top wall E terminates at one end in a free flan e F.

T e rear wall G of each member A is perpendicular to the side walls D and top.

wall E and between its ends is deflected inwardly on an incline as at H and terminates at its u per end in an olf-set portion I which is para lel with the portion G thereof, sa d portion I serving to contract the space be tween said rear wall and'the meeting edges of the side and top wallsof the device. At its lower end said rear wall G is provided with a flange J extending the entire length thereof and at its ends joining the side walls D, the space between opposing flanges when said members A are assembled as shown in Figs. -1, -2 and 3- constituting a longitudinal slot through which the shank K of the bolt or other threaded member is adapted to pass, the upper walls of said flanges J constituting shoulders upon which the nut L engaging the shank K of the bolt is adapted to rest. The rear wall G of each member A is further provided between its lower end and the deflected portion H thereof with a. rib M which extends from one end of the wall D to a oint midway between the ends of said wall lel with said flange J. On the outer face of said wall G and or. the. bottom edge thereof I provide a plurality (if-projections N G, paral each of which is provided in its free end with a recess 0 through which the shank of a mad or the like is adapted to pass, said nail or other fastening device. serving to securethe members A upon the bottom of the mold in which the concrete embedding said device 18 received and the permanent posltion of the device in the wall, ceiling or the formed between said flan s J until it is completely contained in t e hollow space within the device and is then turned until it has assumed a horizontal position and rests must be moved to one end portion of the slot so that the inserted edge will avoid contact with one of said ribs M and any hindrance to its insertion and positioning thus proshank K therewit ment the said nut may obviously be moved vided. After its insertion and positioning the said nut L may be moved longitudinal}? ofthe device to a point substantially mi way between the ends thereof and the threaded member K then inserted and engaged therewith. The said ribs M, when the nut is so positioned, limit the upward movement of the same thus rendering easy the operation of on aging the said threaded After such engagelongitudinally'in either direction and positioned as desired to bring pipe or other.

fixtures suspended or anchored thereby into alinement.

I am aware that inserts having some fea tures of construction in common with m de vice are in use and that the I'BCOI'dSuO the Patent Oflice disclose other patented devices which have some features incommon with my invention, the latter being distinguished from the prior art so far as I am -acquainted therewith in the following features of construction, namely: 3

First: My said insert being made in two parts cast from a common attern and in terlockedavoids the necesslt of the employment of cores in casting t e same without minimizing the strength thereof thus greatly reducin the cost of the casting.

Second: My evice permits of longitudinal adjustment of the bolt or other device without reducing the seatin surface of the nut on the flanges J thereo Third: The depth of the hollow space within the device enables the-shank to be inserted for a distance sufficient for all uroses of adjustment and is of such a width in comparison with the diameter of the bolt so as to. allow lateral play for said shank this being essential especially when the device is employed to anchor heating pipes, or the like, of great length and which therefore, will expand and contract to a very considerable extent under the relativel great variation in temperature to which' they are subjected.

Fourth: By means of the ribs M all diiiiculty in engaging the nut with the bolt after insertion of the former is obviated thus rendering the device more eiiicient than.

It is of course, necessary that the device be made of difierent sizes. to receive and enage nuts of various standard sizes, and? partin fiom the invention as defined in the appen ed claims.
