DOOR HOLDER Filed Jan. '7, 1932 Patented July 4, 1933 UNITED STTA TES - HE RY e. voienr, or NEW HAVEN, CONNECTICUT, AssieNon .To SARGENT & COMPANY,

or NEW HAVEN; CONNECTICUT v noon HOLDER Application filed January 7, 1932. Serial No. 585,321.

' springpperated shaft to which is non-ropivot bolt at the hinged oint and tatably secured an arm having a free end to whichis hingeda second arm pivoted to the door frame. The door check device ordinarily embodies mechanism which tends to urge the door toward closed position. In some inl stallati'ons it is deslrable to have means by which the door may be held in open position against the action of the closing means, and to this end the means is provided adjacent the hinged joint between the two arms to releasably hold the door in a given open position.

One object of this invention is to provide a simple and efficiently acting means to hold the door in open position. i I

Another object. of the'invention is to provide holding means for the door, which can he adjustedso that thedoor may be held in any open position which may be desired.

Another object of the invention is to pro vide a door closer with holding means of the character --'described which will not only be eihcient in action but will be durable and able to withstand continued use fora long period of time. i V j I To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed. i

In the accompanying drawing Fig. 1 is a top plan view of a door holder embodying my invention illustrated as applied to a swinging door; 7

Fig. 2 is a sectional viewthrough the hmged joint between the arms ofthe holder on line 2-2 of Fig. 1; l

Fig. 3 is a detail perspective view of the Figs. 4, 5, and 6 are perspective views of the members comprised in the hinged joint.

To illustrate a preferred embodiment of 5. head 22 is shown in a position reversed from my invention 1 have shown in Fig. 1 a door framelO to which is hinged the door 11.

Upon the door is mounted a door check or closing device 12 which may be of' any approved construction, from the casing of which projects a shaft 13 of non-circular form which is rotated by a suitable mechanism within the casing of the check.

. Upon the upper end of the shaft 13 is disposed'an arm 14 to which is hinged at 15 a secondarm designated generally by the numeral 16 which in turn is pivoted at 17 to, a bracket 18 secured to the door frame 10. T hehin'ged joint '15 will now be described; The arm 14 is provided with a flattened end or head 19 within which is a square opening 20, the face 21 of the head 19 being substantially flat and of considerable area. The

arm 16 is provided with a cooperating head 22 which, as shown in Fig. 2, has an upper fiat face 23 abutting against the face 21 of the. head 19. The lower face'of the head 22 is provided with an inclined surface or spiral 24: as shown more particularly in Fig. It will be understood that in Fig. 5 the that shown in Fig. 2,01 in other words, in upside down relation in respect to the disclosure of Fig. 2. This head is provided with a circular opening 25 to receive the pivot bolt of the hinge as will be explained hereinafter. Below thehead 22 is disposed a washer 26 having an upper spiral fa'ce 27' abutting against and cooperating withthe spiral face 24: of the head 22. The washer 26 is provided with a square opening 28 and the lower face- 29 of this member is substantially flat as is the upper face of the head 19.

The

arms

14 and 16 are connected together by means of the pivot bolt 30 shown in Fig. 3. This bolt is provided with a head 31 abutting against the lower flat face of the washer 26. Above the head 31 the boltis provided with a square portion 32 which is disposed inthe opening 28, and secures the' washer 26-nonrotat-ably to the bolt 30. 7 Above the square portion 32 the bolt is'provided witha portion of circular cross-section 33 which is disposed in the opening25 of the head22 so thatthis head and the arms 16 may rotate relatively L to the bolt. Above the circular portion 33 is a square portion 34 on the pivot bolt, with which the head 19 is non-rotatably engaged, this portion of the bolt being received in the square opening 20 of this head. The projecting end of the bolt is of circular form and screw threaded as shown at to receive the nut 36.

It will be understood, therefore, that the bolt 30 is non-rotatably secured to the head 19 and the 'washer26, but is rotatably secured to the head 22. It will also be apparent that by taking up or backing off the nut 36 upon its threads, the pressure upon the parts of the hinged joint can be regulated so as to determine the position at which the door will be held in open position.

The operation of the device may be briefly described as follows. It has already been explained that the spiral face 24 of the head 22 abuts and cooperates with the spiral face 27 of the washer 26; lVhen the door is closed it will usually be the case that the highest part of the spiral 24 will be opposite the lowest part of the spiral 27. When the door is opened, the

arms

14 and 16 will be moved relatively to each other about the pivot joint between them. In view of the fact that the bolt 30 is non-rotatably secured to the washer I 26 and to the head 19 of the arm 14, the washer 26 will be secured to this arm and will, therefore, have a relative rotary movement with respect to the head 22 when the door is opened. This will result in the relative movement of the two

cam surfaces

24 and 27 so that the head 22 will be urged toward the head 19. The upper flat face 23 of the head 22 will be caused to bind frictionally against the lower flat face 21 of the head 19 due to the fact that the movement of the, parts is limited by the bolt" head 31 and thenut 36, and the result will be that the door will be frictionally held in open position against the action of the closing mechanism of the door check 12. By adjusting the nut 36, the ex tent to which the door may be opened'before the binding action takes place may be regulated as desired. a

' Due to the fact that the. fiat surfaces 21 and 23of the

heads

19 and 22 are of substantial area, the binding action between these parts, when they are forced together by the action of the

cam surfaces

24 and 27, .will be considerable and not only be sufiicient to hold the door open, but will not be readily subject to wear and will withstand a great amount of use. Vhen any wear occurs, it can, of course, be taken up by adjustment of the nut 36.

lVhile I have shown and described a preferred embodimentof my invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit of the invention and within the scope of the appended claims.

What I claim is:

1. A door holder comprising an arm having a head thereon provided with a substantially flat face, a washer non-rotatably secured to said arm and spaced from the flat face of the head thereof, said washer having a spiral surface facing said head, a second arm pivotally secured to the first and having a head lying between the washer and the head of the first arm, said last-named head having a flat face adjacent the fiat face of the head of the first arm, and a spiral face cooperating with the spiral face of the washer and said arms eing connected to a door and door frame respectively whereby opening of the door will effect frictional engagement of the heads on the arms.

2. A door holder comprising a pair of arms connected to a door and door frame respectively and having enlarged heads on theiradjacent ends, and said heads being spaced in superposed relation and having openings therethrough, a pivot bolt having a circular central portion and non-circular end portions, a washer non-rotatably mounted on one of the non-circular portions of said bolt, one of said heads having a circular opening therein to receive the circular portion of said bolt, the other head being non-rotatably mounted on the other non-circular portion of said pivot bolt, whereby one head lies between the washer and the other head, and the adjacent surfaces ofsaid intermediate head and washer being spirally formed to move said intermediate headlongitudinally of the bolt when one arm is moved relatively to the other to bind said heads frictionally together, and enlarged end portions on the bolt to hold the parts assembled;

I In witness whereof, I have hereunto set my hand this 5th day of Jan, 1932.

HENRY G. VOIGHT.
