To all 'whom it may concern:

Be it known that l, CLAnnNcn l-l. BLACK- ALL, a citizen or the United States'otlmerica, and resident ot Cambridge, in the county ot Middlesex and State or Massachusetts., have invented new and useful llmprovements in Building Construction, of which the iollowing is a specification.

This invention relates to building coinbinations and more particularly to construc. tions whereby chairs, tables or other isolated or grouped objects may be adjustably 'attached to doors, walls, ceilings or other portions oit' a building formed entirely or' in part oit concrete or other cast, moulded or troweled compositions.

linlastening theatre chairs to a concrete iloor, lor example, it is desirable to align the chairs either in straight lines orA in curves andV also to space them uniitoriiily apart.

ln the case of sloping iloors it is also necessary to lasten the chairs in an inclined position relative to the Jdoor in order to have them properly positioned relative to -the horizontal.

llereto'fore it has been customary to drill holes in the concrete, insert expansion bolts into theholes and then screw into the expansion bolts. Unless the holes are drilled with extreme accuracy, they do not match the holes in the le s of the chairs, and after the holes are dril ed it is impossible to adjust the positions ot the chairs. Moreover, the concrete is weakenedby drilling the holes and the expansion bolts tend to pull out.

lhe objects of the present invention are to overcome the difficulties incident to prior construction and to 'provide a construction whereby the chairs or other articles are tirinly -but adjustably held in position, whereby the door or other surface is not mal terially weakened, whereby whereby the articles may be readily adjusted and attached in proper alignment and prop'- erly spaced, either in a horizontal or inclined door, and either in curved or straight lines.

According to this invention there is einployed a series of anchors or bolts connected to a continuous slotted tapped or curved piece of: steel or other material which is set in the cast, moulded or troweled surface cl concrete,l or other composition of combined materials, so as to serve as guides for the the attaching means is securely anchored in the floor and v levels of the nished door or other surface and also as attachments for adjustably securing furniture or other objects., With my construction the objects maybe attached by a singlebolt or other fitting, the iitting being similar for all levels or pitch of floor and so arranged as to permit of play crosswise andtrom iront to back to take up any inequalities in setting the inserts in the concrete or other material.

ln order to disclose the nature of the construction l have illustrated it as applied to a theatre door and a portion of a theatrel chair attached thereto according to this invention;

lF41 ig. 2's a vertical longitudinal section through the construction;

liig. 3 is a vertical transverse section on line 3-3 of Fig. 2'; i Y

Figs 4C, 5 and 6 are perspective views similar to llig. 1 showing modifications;

llig. 4a is an enlarged end view of channel andassociated parts shown in llig. l; and

Figs. 7 and 8 are plan and elevation views, respectively, of a different application of the invention.

ln the particular embodiment of the invention illustrated in Figs. l, 2 and 3, 1 represents a floor of cast or molded material, such as concrete, the floor having steps 2 as in theatres, 3 and 4c represent legs of a chair and 5 represents a wood form upon which the floor is molded. An elongated tubular member 6 in the form of a channel is built into the door, the channel member having overhanging portions in the form oil inturned anges 7 separated by slot 8, the

`flanges being substantially Hush with lthe top surface ol the licor. The channel member not only serves as attachment means but also to guide the level in forming the floor surtace. rlhe channel member may be anchoredin the door by means of straps 9 extending over the channel member and thence downwardly to the iloor. rlFhe straps 9 have feet l() which serve temporarily to attach the anchor to the woodl form 5 while the iloor is being cast and which also serve to prevent the anchor from being pulled out after the construction is finished. Associated with the chair legs is a yoke 11 having down-turned bifurcated legs adapted to interit with the feet of the chair legs and having a .slot throughout its widened central portion. Fitting over this yoke is a Ushaped clip 13 provided with a centre openmg.

A bolt 14 having a head 15 disposed in the channel G extends upwardly through the slots 8 and 12 and through the clip 13, nuts 16 being threaded on the upper end of the bolt. The head 15 of the bolt is elongated as shown in Figs. 2 and 3 so as to underlie the overhanging flanges 7 of the channel 6 in normal position and so as to be removable through the slot 8 when turned 90.

Insecuring a chair in position, the yoke 11 is interengaged with the chair feet, the clip 13 is place over the yoke 11, the head of the bolt 14 is placed in the channel 6, the shank of the bolt is extended upwardly through the yoke 11 and clip 13, and the nuts 16 are then threaded on the upper end of the bolt. Before the nuts are tightened, the chair is adjusted .in the proper position, the bolt 14 sliding 1n the channel 6 for longitudinal adjustment and sliding in slot 12 for transverse adjustment. When the chair is in proper position the nuts are ti htened.

f '1t is desired to have no project1ons extending above the surface of the floor,

the strap 9 may be omitted or replaced with anchoring means which do not extend above the floor surface. If the chairs (or other articles) are to be arranged in curves, the channel 6 will be curved at the desired degree of curvature.

The modification shown in Figs. 4 and 4a is similar tothat shown in Figs. 1 to 3 but differs in the following particulars. The channel member 6 is narrower at the top than at the bottom and the flanges, instead of merely being turned in 90 as in the preceding figures are folded inwardly through approximately 180 and then folded outwardly again through approximately 180o, s that each flange comprises two substantially vertical portions lying side' by side. An important feature of this construction consists in that only narrow portions of the beam are exposed at the floor surface, namely the portions joining the flanges with the sides through substantially 180 folds. Another feature of this modification is that the attaching bolt 14 engages the flanges 7 edgewise, instead of fiatwise as in Fig. 1, thereby affording greater strength and rigidity. Another feature shown in Figs. 4 and 4, which is not shown in Figs. 1 to 3, consists in bending the strap 9 inwardly beneath the channel 6', to form shoulders 17 adapted to support the channel 6' on opposite sides while the concrete is being built up. It is to be understood that this feature, may be employed in the construction shown in Figs.

1 to 3. In Fig. 4 the yoke 11 is formed integrally with the chair legs instead of deformed of two straps 18 and 19, the straps being bent at 20, 21, etc. to hook over the flanges on the chair legs. In this construction the U-shaped clip 13 also functions to hold the two straps 18 and 19 together.

The modification shown in Fig. 6 differs from that shown in Fig. 5 in that the yoke comprises two angle-iron pieces 22 and 23 having horizontal portions resting on the chair feet and vertical portions extending upwardly along the chair legs. In this construction, as 1n the construction of Fig. 5, the clip 13 holds the two parts of the yoke together.

In the event that it is desired to -secure articles in other than a straight line, as for example in fastening theatre seats in a curved row, the channel members are made in sections and joined together as illustrated in Figs. 7 and 8, where 24 and 25 designate two adjacent sections of the channel. These sections are joined by means of a strap 26 which is riveted or bolted through the under side of the channel 24 as indicated at 27 and is detachably connected to the channel 25 by means of a lug 28 fast in the other end of the strap 26 and extending upwardly through an openin in the bottom of the channel 25. As s own, the ends of the channel members are preferably beveled so that the may be set close together at an angle. bviously this angle can be readily adjusted in attaching the channels.
