With the axis ot-the shaft ying below'the buckle line, a positive brace is formed and any effort to open the door 8;, in the direction of the arrow as (which is the only way t;

theoloor can be opened) would result merely in forcing the brace more firmly into the floor and door. Since there are two holes 12' and two holes 14, withcorresponding prongsi for the brace to swing around or to be forcedaround into.theopposmg'position where it might be buckledby the opening of the door. Thus itis impossible fora person to introduce a case knife under the door to at- 0 feet the position of the brace 17v and 18 with any efl'ectiveresults.

As an ancillaryfeature, I provide We cautionary means in the nature of a staple 23 [which rides inthe portion 24 ofthemernber 1 on the members 17 and 18, it is impossibleea 'trated in Fig. 2.

shown in dotted lines in Fig! 2,"the' staple 23 is withdrawn so as to occupy thep'osition shown in dotted, line in Fig. 5. \Vhen, however, the parts are jammed down into the position shown in full line in Fig. 2,-=the staple 23 is in line with the sockets 25, 25 and is pushed down into the sockets, as illustated in full lines in Fig. 5, to form the positive lock.

As a further precautionary feature I provide a small leaf spring 26 set in the'member 18 and engaging the member 17, as illus- The idea of this device is to prevent the release of the two members by any possible play in the door. Thus, assuming the staple 23 to be out of use, it the door should have a slight play in the di rection of the arrow 1 it might be possible 'to shakethe door to release the upper prongs from the holes therein. However, with the presenoe'ofthe spring 26 the member 17 is made to follow the shaking of the door and cannot be released from the openings in which it engages.

In 'F G I have shown a modified form of the member 17 where only one prong is provided instead of two. It will be seen that even m'that event the swinging of the brace is prevented by reason of the double prong arrangement invariably on the member 18.

It will be obvious that my brace may be applied to prevent movement between any two parts, such as the two sashes of a win dow, as well as to prevent movement between a'door and a! floor. It willalso be "cleart hat it is not necessary to employ the plates'l'l and 13 but that the door and floor, on the other hand, may themselves be provided with small openings in which the positi0n, bcingdisposed outof alinemcnt with the line of stress between the objects held, means to takeup lost motion between said sections and means engaging through both sections adjacent their junctions to prevent" accidental relative movement of the sections when in holding position.

2. In combination, a pair of linked sections, the free ends-of which are adapted to impinge .upon two objects between which relative movement is prevented, said sections having engaging shoulders adjacent their junctiomand a flat spring carried by one of theshoulders to engage the other shoulder and prevent lost motion between the sect-ions.

In witness whereof, I hereunto subscribe my name this 4th day of April A. D. 1916 HARRY B. i ROBERTS.
