'To all whom it may concern:

Be it known that I, MARVIN H. .JEs'rnR, a citizen of the United States, residing at Philadelphia. in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Plaster-Board Supports, of which the following is a specification.

This invention relates in general to plaster board supports, and more particularly to supports by which sheets or blocks of plaster board may be attached to the concrete beams of a ceiling.

One of the primary objects of this invention is the provision of a support of this character which can be quickly and accurately placed in position before the concrete of the beam is poured and which, whenpositioned, can be quickly and easily engaged withthe plaster board as it is applied and will securely and firmly support the plaster board in position.

Another object of the. invention is the pro vision of a support which shall consist of a series of individual clip members. arranged in the required spaced relation andfastened together so that thewhol'e series can be simultaneously positioned and when positioned, will be disposed in parallel .relation and in the proper position;v

A further object .of my invention is to provide a support of this character, which may be closely associated with the concrete reinforcing rods of the structure so that the supports will occupy but little space, and also to provide a support which can be cheaply manufactured, quickly placed in position, and which will be strong and durable in use. p

Other objects and many of the advantages of my invention will be readily appreciated by those skilled in the art as the same becomes better understood,by reference to the following description when considered Tin connection with the accompanying drawin 's:

'lieferring to the drawings Fig. 1 is a perspective of one of the clip members of my invention, 7 H a Fig. 2 is a transverse sectional view through a ceiling beam equipped with a support embodying my invention;

i Fig. 3 is a perspective view of one of the connecting wire elements;

F ig. 5 is a fragmentary view looking upwardly at the reinforcing rods of a beam with my support in position, the concrete beneath the rods being removed .to more clearly illustrate the application of my invention;

Fig. 6 is a transverse sectional view on the line 6-6 of Figs. 2 andt;

F 7 is/a perspective view of a modified form of my invention, and n Fig. 8 is a detail of the modified connectin link. 7

From an inspection .of the drawings and more particularly Fig. 1. thereof, it will be observed that my invention comprises essentially a series of clip members, one of which is shown in Fig. 1. These members are made .of sheet metal of suitable weight, which is bent into substantially inverted channel-shaped form as shown, the channel shape body portion 7 being of a length slightly less than the width of the beam in which it is to be imbeddec. tween its ends,

Be this channel shaped member is cut away to provide two transversely disposed seats8 and .9, adapted to accommodate a pair ofparallel concrete reinforcing rods such as are indicated at 11 and 12 in Figs. 2 and 4. I

Each clip member is formed .to provide laterally extending

flanges

13 and 14 respectively of appreciable width, these flanges being each severed throughout substantially one half of its lengthfrom the body portion of the member as indicated at 15, so as to leave a portion of the flange free to be bent downwardly upon itself to form a plaster board supporting clip. The position of the flanges when bent into plaster boardsup Fig. 2, wherein the free end of the flange 13 is indicated by reference character 16 and the free end of the flange lt is indicated by reference character 17." It should be noted that these flanges are severed. at opposite ends of the body portion so that they b nd own ard y in Oppos e d re t ons to nga e the opp se ge of plast boa s n ice ed .in'iFig. 72 y .1 a d re p c i ely I B for the e members a e p aced. in pos ti a Serie o thema e onneetedt ge he s that h y fe n siesta tringer cha ceiling of clip members connected together elld'hld 1' in parallelism in the proper spaced relation. For the purpose of connecting a series of these clip members together, I employ a series of wire loops 21, one of which is shown in Fig. 8. These loops are slightly narrower than the overall length of the cllp members and the ends of each clip member are provided with inwardly extending slots 22 to accommodate the sides of these loops. Each loop is adapted to embrace two clip members, the ends 23 of the loop being engaged with the longitudinal sidewalls of the clip members as shown in Fig. 5, 1n which only one clip member 7 is shown, but the position of the overlapping wire loops being indicated, from which it will be apparent how a clip member is embraced by and held between two of these loops. The ends of the wire loops will, of course, prevent the clips from separating, but to in sure that the members will be retained in the proper spaced relation and will not move toward each other, I prefer to bend the longitudinal members of the wire connecting elements inwardly, as indicated at 2d between the side walls of each clip member as best shown in Figs. 3 and 5, so that these inwardly bent portions prevent movement of the clip members longitudinally of the wire connecting links or elements and insure that these members will be maintained in parallelism and in the proper spaced relation. One of the members embraced by two of the wire connecting elements 21 is clearly shown in Fig. 6. p

In the use of my improved support, a series of these clip members is connected together by wire connecting elements in the manner described, to form a chain, which is then placed in position in the body of the mould into which the concrete for the ceiling beam is to be poured. This mould is then placed in position around and beneath the concrete reinforcing rods with the clip members disposed beneath the rods and in engagement therewith, the seats 8 and 9 formed in the members, permitting these members to be closely associated with the rods so that they extend upwardly a considerable distance into the body of the beam insuring a firm anchorage, but at the same time it will be observed that they occupy but little space beneath the reinforcing rods so that the depth of the beam need not be increased over the normal.

After the series of clip members have been positioned in the mould as explained, the concrete is poured and while in its semi-liquid condition, it flows into the ends of the clip members and into the seat openings around the rods, which are made larger than the rods to facilitate the entranceof the concrete, with the result that the concrete completely fills the interior of the clip elements, as shown in Fig. 6, thereby firmly bonding and securely anchoring the elements into the body of the beam, which is indicated in Figs. 2 and 6 by reference character 25.

After the beam has set and the moulds have been removed, the flanges 13 and 14: of each clip member lie substantially flush with the bottom of the beam. In order to apply the plaster board which forms the ceiling, it is onlynecessary to bend the free ends of each flange downwardly and back upon itself, as shown in Figs. 2 and a, to form the fastening clips by which the plaster board is sup ported. This bending of the flanges may be readily effected with a hammer or other preferred tool, and it can be done very quickly. When the clips are bent over beneath the end face of the plaster board. they serve to firmly and securely support it in position and since the clips proper are relatively thin, a thin coat of plaster over the whole surface is sufiicient to completely cover and hide the clips from view.

In some instances, as a matter of additional security, it may be desirable to nail the clips to the plaster board and in order that this may be done when desirable, I provide the free portion of the flanges which form the clips proper with a hole 26 near the free end thereof, while the opposite fixed end of the flange is beveled off as indicated at 27, so that when the free end is bent downwardly and back upon the fixed end, the hole 26 is disposed longitudinally beyond the beveled end 27 so that a nail driven upwardly through the hole 26 and through the plaster board will not engage the fixed portion of the flange, but may pass upwardly through the plaster board beyond the end of the flange.

In Figs. 7 and 8 I have illustrated a modified form of connecting link which may be used in lieu of the loop links 21 previously described. In this instance, the link consists of a longitudinal portion 28 provided at one end with an eye 29 and at its other end with a transversely disposed portion 31 terminating in a reversely bent hook 32. A series of these links may be united by inserting the transverse hooked portion 31 of one link through the eye 29 of the adjoining link, whereupon the hooked end 32 is engaged with a clip member 7, as shown in Fig. 7, thus connecting a series of these members together so as to maintain them in definite spaced relation.

It is believed that the construction, mode of operation and many of the advantages of this invention will be understood from the foregoing without further description, and it should be obvious that various changes in the structural details illustrated and described may be resorted to without departing from the spirit of the invention, as defined in the following claims.
