Application filed March a, 1928.; SeiiallNO 258,791]

Therpresent invention relates to ade'vice for checking the movement of a hinged mem her in respect to its support and more particularly to a door check.

The prime object of the invention resides in the provision of a hinged structure check mechanism of this nature wherein the hinged meinberis urged to a'n'ormal position fromi which it' may be moved toa limited predeterminedexte'nt. Another very important object of the 1nstructure check mechanism ofthis nature including means between the hinged structure and a support for urging the hinged structure to-a predetermined position, the connection between said means and said supporting structure being of a slidable nature and capable of being held in a predetermined po sition for normal operation.

. A further important object of the invention resides inthe provision of a hinged structure check mechanism of this nature possessing 'meansfor holding the hinged structurein a predetermined position against the normal urge of the mechanism.

" A still further very important obj ect of the invention resides in the provision of a mechanism of this nature possessed of an exceedingly simple construction which is both strong and durable, inexpensive to manufacture, easy to apply, convenient to operate or adjust,

' and otherwise thoroughly efiicient and re;

liable inits use and operation.-

With the above and numerous other objects in View aswill appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination, sub-combination and arrangement of parts as will be hereinafter more fully de scribed and claimed. In the drawing:

Figure 1 is atop plan view of the me'cha nism embodying the featuresof this invention showing the same associated with a supporting structure with a hinged member mounted thereon,

Figure 2 is a sectional view t'akensubstantially on the line 22 of Figure 1,

Flgure 3 is a sectional view taken substantially on the line 33 of Figure 1', Figure 4 is a sectional view taken substantially on the line 4-4 of Figure 1, Figure 5 is a perspective viewof a rail, 4 Figure 6 is a perspective view of a slide.

' preferred structure and do'not Referring to the drawing in detail it willbe seen that the numeral 5 denotes a supporting structure and the numeral 6 a hinged member which will be referred to in the present exemp-lification of the invention as a wall and door'respec'tively. The door 6 is hinged to the wall 7 for the purpose of closin r a door way. The parts thus far described, of course, are conventional and may be of any form a part of-the present invention.

The numeral 8 denotes a .rod slidable in a tube 9 one end of which-is open to'receivethe rod 8 While the other end is-closed and has formed thereon a pair of spaced parallel'ears 10 A spring 11 is disposed in the tube 9 andimplnges against the inner end of the rod 8,. and the closed end of the tube 9. A bracket denoted generally by the letter B connects the outer end of the rod 8 with the door 6 preferably adj acen't, the top thereofand the intermediate portion thereof considered horis zo1'1tally;,. This bracket B comprises a U- shaped section 12 which terminates in outwardly directed ears 14 secured to the door by suitable fastening elements The bracket further comp-rises a second U-shaped section 15 one end of which terminates in a laterally extending curved extension 16., The bights of the sections 12 and 15 are connected by a rivet 17 or other suitable means. The outer end of the rod 8 terminates in a latwhich extends through openings in the ends of the sides of the section 15 thereby hingedly connecting the rod 8with the section 15. I have therefore provided a connection between the-door and the rod 8 i a An elongated rail bar is secured to the wall 5 toextend horizontally thereof or at right 'anglesto the axes of the hinges 7. This rail is preferably formed-of a single sheet of metal bent to provide a U-shaped cross sectional formation so as to include a bight plate 21 having a side plates 22 projecting outwardly and preferably perpendicularly to the plate 21 at the upper and lower edges thereof. The side .plates 22 merge intoflanges 23 and 24, the former extending upwardly and the latter extending downwardly. The flange 23 at itseral bearing 18 for receiving a pivot pin 19 4 ends is provided with a. pair of inwardly extending stop lips 25 and on its edge adjacent one en with a notch 26.' A slide S preferably comprises a sheet 27 bent over upon itself at its longitudinal edges to provide flanges 28 extends between spectively.

and 29 for receiving the flanges and 24 re-.

The slide s. saima1-a 'nbah. so I which should be registeredwith the notch 26.

Alu

31' projects from 'the sheet a 27 of the slide between the cars 10 and a pivot pin 32 o enin' sin saidfiears and said lugs to hingedly connect the slide with the tube 11. A latch 33 is in the form of a rod havin aneyem at one end and a lateralextjen'slon 35 at the other end. A ivot 36 on emplification ofthe inventipn' it will be'seen that to open the door 6 the spring 11 must'be compressed in the tube 9 because of the sliding of the rod 8 into said tube and therefore as soon as the doorisreleased it will return to a closed position b the expanding of the spring forcing the r0 outwardly of the tube and thus the door will normallymaintained in a closed position. I a It willfurther be seen that by opening the door a predetermined distance the curved ex= tension 16 may be brought into contact with the bail 38 so as to swing the bail 38 upwardly until it slips over the upper end of the extension-16 and then the door will be held in an open position. In this open position with the parts disposed asindicated in the drawing the door would extend at approximately right angles to the doorway. If it is desired to 0 en thedoor still farther the latch 33 may be li ted out of the

notches

30 and 26 and the slideS slid along the railR. It will be seen that the stops 25 prevent the slide from coming off the When thedoor is wide open'andagainst the wall it will beheld fast to the wall by a latch or hook which-is fastened to the wall and which engages the door so that it will remain stationarylxand not be affected by winds or storms.

A consideratiomofthe cooperants in their essential functional .corelationship in the present exemplification of the invention will make it quite apparent that the mechanism is not limited tothe use with a door but is adaptable'to anyhinged structure for maintaining the. sanie in a predetermined position. I, therefore il o not wish to be limited in any way to the' .particular utility brought out in the presengt'g 'exemplificatiofi. It is further to beunderstood that'the present example of the invention exclusive of the wall erence onl movement thereof.

engaglng with the extension and ineans and door has been disclosed by way of pref- Q since in actual practice it attains the eatures'of-advantage enumerated as desirable inthe statement of the inven tion and the above descri tion. It is quite apparent, however, that c anges in the details of construction, and in the combination and arrangement of parts may be resorted to wi hout departing from theflspirit-or scope of the invention as hereinafter claimed or sacrificing any of its advantages. y

Having thus described my invention, what I claim as-new is:

l. A hinged structure check mechanism of the class described comprising a pair of slidably'connected members,-means urging the members in extended relation to each other, -means for connecting one of said members to a hinged structure,'and slidable':

means for connecting the other member to a fixed structure, said slidable'means comprising .a releasable mechanismior preventing 2. A mechanism of theclass described comprising a pair of slidably connected members, a slide hingedly connectedv with one of the members and-formed from a plate having; overhanging flanges, a rail of elongated construction flanges to be received in the first mentioned flanges, a hinged bracket out-he other member, and means of a releasable nature for holding'the slide against movement on the rail. f

3. A mechanism of the class described comprising a pair of slidably connected. members, a slide hingedly connected with one of the'members and formed from a plate having overhanging flanges, a. rail of elongated construction, flanges to be received in the first mentioned flanges, a hinged'bracket on the other member, and means of a releasable nature for holding the slide against movement on the rail, said means comprising a hinged latch, said slide and said rail having registrable notches in which the latch may engage to prevent movement of the slide on the rail.

4.. A mechanism of the class described comprising a pair of slidably connected members, means urgin the members to. a predetermined position in relation to each other, a

bracket hingedly mounted on one of the menr 110- ,bers' and having a curved extension, a bail hingedly mounted on theother'member for for mounting said other member.
