rLAsrnn-BoAnn s'run AND LOCK Application filed February 13, 1929, SerialNo. 339,608. Renewed January 28, 1932.

This invention plaster board studs and locks and may be considered as an 7 struction disclosed in my prior Patent No. 1,697 ,521, issued January 1,1929..

An object of this invention is to provide an improved plaster board stud and lock wherein the stud has a plurality of circular'perforations or apertures therein, adapted "to receive the looks or keys which are caused, on rotation,- to bind in the apertures so that they will fasten the plaster boards firmly to the studs. r I

Another object of the invention is to provide a'plaster board lock or key which may be easily, quickly and cheaply constructed out-ofheavy wire or'similar material and which is, to a certain extent, resilient so that plaster boards engaged thereby, causing the plaster boards to be continually and tightly held against the studs.

A further object of the invention is to-pro board key or look which is so plaster board to a stud. By such a construction it is possible to assemble the plaster vertical in staggered relation, employing some keys or locks at the ends of others at their centers.

Another object of the invention is to pro-' vide a plaster board wall construction wherein the plaster boards are assembled with their vertical joints in staggered relation.-

.With the foregoing and other objects in.

view which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference,

is had to the accompanyingdrawing for the illustrative embodiment of the invention, wherein:

Fig. 1 is a partial view in perspective, illustrating the improved plaster board wall construction in the process of erection and illustrating the improved studs and locks.

Referring to the accompanying drawing wherein similar reference characters designate similar parts plaster board wall construction comprisesa plurality of vertically arranged studsjlO. These studs, in the preferred form of construction are channel irons having a row of perforations 11 formed in each of its sides. The perforations 11 are circular or approximately circular in form and are adapted to keys or looks. Sevreceive the shanks of the eral different types of keys or locks are provided which may be optionally employed or which may be substituted, one for the other. The preferred form of lock is shown in Figs. 21 to 5, inclusive and comprises a shank l2 slightly smaller in diameter than the diameters of the perforations ,11 so that it may be easily inserted in the perforations. At the'top of the shank there is a head which extends laterally from one side of the shank only. The head in the modification shown in Figs. 2 to 5, inclusive comprises two por tions indicated at 13 and 14;. are arranged at an angle toeach other which, is slightly less than tween the shank12 and the portion 13 "is slightly less than- 90 degrees.

7 As clearlyv shown in Fig. 4 the shank is,

not only inportion 13 but is inclined also reality forms an angle slightly less than 90 plan view of oneof the keys taken in the direction or throughout, the improved These portions 90 degrees and the an I partial view in elevation ofastud illustrating the manner in which a lock degrees with the plane which contains ter board P is placed against the wall and a the portion 14 is plurality of the keys and their shanks positioned in the perforations 11.-

der side of the portion 14 is slightly lower or behind the outer surface of the plaster boa-rd P. The key is then rotated, causing the portion 14 to be'sprung slightly and tobe slidover the outer face of the plaster board. The rotation and tension placed on the key causes the shank 12 to bind in the perforations so that it cannot the perforation. Also, by virtue of the inclination of the shank to the portions 13 and 14 of the head, a screwing or tightening action takes place during the rotation. After the portion 14 has been swung over the outer face of the plaster board the rotation is continued until the portion 13 is also over the plaster board. An adjacent plaster board P can then be positioned against the shank and the key then reversely rotated'until it assumes the position shown in Fig. 3 where-- in the portion 13 of the head extends over the outer face of the plaster board P and lappingv or extending over thevertical joint between the plaster boards Band P Inthis manner a single key can be caused to hold the marginal edges of two adjacent plaster boards tightly and firmly against the stud. The resiliency of the key causing it to act like a spring pressing the board against the studs. 7 p v A feature of the invention resides in the fact that the perforatlons 11 are circular in form and the tighteni-ng is effected by the rotation of the shanks 12 on substantially their own axes. By thus having theperforations small in diameter and circular the strength of the studs is, adequately preserved and also no lateral or longitudinal sliding need take place to lock the. plaster boards tothe studs. This feature is also important in that it enables a plaster board wall to be constructed wherein the vertical jointsbetween the plaster boards are broken or are in staggeredrelation as shown in Fig. 1. The plaster boards may have-apertures therein of approximately the same size as the perforations 11 and the keys may be extended through the apertures into the studs and tightened therein. Such keys will be located at the centers so that each plaster board will be firmly locked in place at its center as well asat its 7 ends. Theadvantages of having broken or They are pushed into the perforations sothattheun be withdrawn from formed of the plaster boards These keys are of substantially the same construction as that shown in Figs. 2 to 5 inclusive, with the exception that the portion .13 on the head is much shorter than the portion '13, The inclination of the shank 12 with respect to the portions 13 and 14 issubstantially the same as the inclination of the shank 12 with respect to the portions 13 and 14. V

In Fig. 8 there is a further modified form of construction 'whereln the key is shown as haying a shank15, a laterally. extending head 16, and a' downwardly bent end 17. The shank 15,as shown, forms an anglewith the head 16 slightly less, than ;90degrees, so that when the end 17 is pressed against the plaster board it will tend to cause: the .shank 15 to tilt slightly in the aperture 11; and to bind therein. r r
