DOOR HOLDER Filed April 22, 1933 2 Sheets-Sheet 2 Patented Sept. 3, 1935 T'TE t ne

This inventionrelates to door holders and particularly such devices of the type wherein means are provided for securing the door in open position at a predetermined limit of swing.

6 One object of the invention is a novel and improved door holder mechanism which is readily adaptable to both right and left hand doors, which optionally automatically locks the door in the open ,position, and which protects the door and mecha- I 'nism against undue shocks and strains at all times by permitting'cushioned movements of the door inboth directions. A further object of the invention is a door holder mechanism of this general character which is characterized by the simplicity of itsparts and mechanism, and by its ruggedness in construction and dependability in operation.

The several features whereby these and other objects may be attained will be readily understood'frorn the following description and, accompanying drawings in which: s s

I have illustrated my invention as embodied in s a pair of ears or jaws 9 and iii projecting outward- "lyfrom the plate right angles thereto. 7 The arm 2 is in the form of a heavy bar reduced in thickness at its outer end to form a tang or plate H which is supported between thejaws 9 ,and iii of the bracket 7 and is pivotally fastened 1 thereto bynieans'of a removable pintle it pass- 'a door holding mechanism comprising a pair of,

through registering openings formed inthe, jaws?) and lilandthe tang il. The pintle l3 hasa' head it which] is countersunk into a recess formed in the'jaw 9, and the pintle is anchored in position by means of a lock screw 29 which is screwed into the jaw 9 and engaging a niche formedthe head i l. The tang H is provided with a stop lug or heel l5 on oneside thereof, thislughaving an abutting face l5' which engages tne face of the plate 8 and limits in one dirctioflthe angular movement of the bar 2 h f i t O e plate and d oor. 'Ifhebracket lf issymnietrically constructed, that is, the jaws SfaLri'd ii) are disposed at right angles to the plate land the plate 8 projects to both sides thereof in the planesof the jaws; and, as will hereinafter appear, the door holding mechanism may be readil'yada'pted to either a righthand or lei'thand swinging doer by merely reversing the position of' the'bar 2 with respect to its top and bottom fa'c'es or by turning it over with the lug or stop ltfdisDOSe'd onthe opposite side, in whichreverse positioii' thelug: engages the opposite projecting side 'of the plate Set the limit of angular movet;

There is a single locking means cooperating with thi'sreversiblebar and stop lug and this comprises a hand'ma'nipulated locking plunger it which is cjarrledby the jaw ill of the bracket and cooperates witha recess it formed in the tang or plate II; This. plunger is located eccentrically with respectto the pivotalaxis of pintle it and also symmetrically with'respect to the projecting sides of the plate 8, that is in the plane including the axis of the pintle and disposed atrlght angles to the plate 8 in order to obtain the symmetrical disposition thereof, and in the particular embodiment shown this plunger is located on,the opposite side of the pintle from the plate 8.

V The plunger I8 is upported in the depending tubular housing 20, the latter being integrally formed with the lower jaw IQ of the bracket, and is, normally urged upwardly through an opening 21' formed in'the lower jaw Ill and registering with thetubular housing. Plunger i8 is normal- 1y urgedupwardly by spring 22 held betweencollar ZS'of plunger IB and retaining washer 24, the washer t lloosely surrounding the plunger and beingheld within the housing by a suitable bushing 25 which is screw threadedly attached to the housing, Bushing 25 is provided with grooves 26 in which a pin 2 7 of latching plunger I8 slides when inoperative position, the plunger being placedin operative position when the pin 21 is aligned with the grooves 26.

The recess [9 formed in the tang H of the bar 2 is so positioned that when the stop lug [5 engages the plate 8 or the door the plunger [8 is in register therewith. The stop lug l5 projects outwardly from tang II and is offset from the center line of the arm 2 and the abutting face l5 of lug l 5 is disposed at an acute angle to the center line 39 of the bar 2. The locking recess or opening I9 is likewise offset from the'bar 2 and with the lug iii in engagement with the door or plate 8 the center line of recess I9 is disposed in the plane passing through the axis of the pintle l3 and at right angles to the plate 8. In the particular embodiment shown, namely, where the plunger I8 is disposed on the opposite side of the pintle I3 from the plate 8, the recess [9 is offsetv from bar 2 to the opposite side from the lug l5. The inner ends of the arms I and 2, as above indicated, are joined together for relative swinging movements. The inner end 40 of the arm I 1 is offset from the main body thereof (Fig. 3') and is provided with a fiat bearing surface cooperating with a similar flat bearing surface on the end 4| of the bar 2, the end 4i being slightly reduced in thickness from the thickness of the bar 2. The ends 40 and 4| are maintained in bearing engagement by means of a bolt 42 passing through registering openings formed therein, but this bolt 42 takes no part in the longitudinal strain or force placed upon the two bars I and recess 43 when the two bars are held together.

These'cooperating female and maleparts are of comparatively shallow depth and are capable of transmitting the maximum strains put thereupon with the desired factor of safety. The end M of the bar 2 is, as above indicated, made symmetrical on both its upper and lower sides so that merely by reversing the positionthereof it may be adapted to either a right hand or left hand door. For this purpose the corresponding cooperating strain transmitting member on the end 4| of the bar 2 is duplicated on both sides thereof and accordingly the bar 2 is provided on one side with the cooperating member or part 44 and on the opposite side with an identical part 44','the latter functioning with the cooperating part 43 of the bar I for the reversed position. The cooperating faces and bearing surfaces of the ends 49 and 4|, including the male and female bearing parts 43, 44, 44" maintain the two bars l and 2 in alignment, take up the wear and assume the shearing forces or strains ordinarily put upon the pivotal axis and the fastening bolt functions merely as a means for holding the parts in cooperative engagement and relation.

The outer end of the arm I is fastened in any suitable manner to the door frame 4. For example, as illustrated, a substantial or heavy bracket 46 is illustrated having a flat plate 41 with openings therein for securing the bracket flat against the frame member. The plate 41 is reduced in width and has integrally formed therewith, an ear or jaw member 48 with a pintle 49 passing through the ear or jaw 48 and plate 41 and functioning as a pivotal connection for the outer end of the bar I. The plate 41 has an elevated or thickened part 50 in the vicinity of the jaw 48 for forminga bearing surface and providing the desired clearance between the arm or bar I and the plate 41, the bar I having its end flattened out, as indicated, at 5| with surfaces parallel to the plate. I

The holder is also provided with means cooperatively'related to the reversible bar 2 and the locking mechanism for absorbing shocks and taking up undue strains which may be put thereupon during operation. For this purpose one of the members or arms I or 2 is provided with a cushioning and yielding means permitting a limited amount of longitudinal yielding in either direction when it is attempted to force a door past the full open position in opening or in attempting to force the door in either direction when locked in stop position. In the particular embodiment shown the bar I is provided with such means. It is formed in two parts an inner part 52 and an outer part 53, these two parts having telescopic sections 52 and 53 respectivemakes a slidable fit with the bushing 54 and is' further reduced to form a stem 51 around which is disposed a compression spring 58, one end of the spring engaging a washer 59 which in turn engages a pin 60 carried by and fixed to the stem 5?. The other end of the spring engages both the shoulder 54' formed by the end of the bushing 54 and the shoulder 56' of the reduced cylindrical part 56, the outer diameter of the spring being greater than the inner diameter of the bushing 54. The hollow telescoping part 53 is provided on the interior thereof with means engaging the collar 59 on the opposite side from that engaged by the spring so that when the member 52 is moved to the right (Fig. 4) a force is exerted upon the spring, the other end of the spring being engaged by the shoulder formed by the reduced cylindrical part 55. In the particular embodiment shown herein this means comprises a sleeve 63 carried inside the hollow part 53' with one end of the sleeve engaging the collar 59 andthe other end of the sleeve abutting the solid part of the member 53. The sleeve 63 is provided with grooves 64 for accommodating the ends of the anchoring pin 69 and permitting the relative movement of the member 53 with respect to the member 52 (Fig. 4). The bushing 541s provided with a skirt 66 in telescopic relation with the enlarged part 52'. The parts of the bar I may be readily assembled as follows:

The bushing 54 is inserted in position over the reduced cylindrical part 56 of the telescoping part 52', then the spring 58 is inserted over the stem 5] and the collar 59 and pin 60 inserted in position with the spring engaging. the collar 59 at one end and engaging the shoulder 56 formed by the reduced part 56 at the other end. Then with the sleeve 63 inserted within the telescoping part 53' the telescoping part 52 is inserted into the hollow part 53 withthe collar 59 engaging the sleeve 63 andthe pin 60 in registry with the slots 54 whereupon the bushing 54 may be screwed home to form a part of the hollow telescopic part 53 with its shoulder in position to engage the spring 58 which, as above described, also engages the shoulder 55' formed by mechanism which is adapted to various uses of such mechanisms" and particularly" adapted to withstand rough and heavy usage. Withthe door in closed position. the plunger I8" rides upon the fiat surface of thetangII or end of the bar, but

when the door is opened to the desired extent,-

namely, when the face I of lug I5 abuts the door or plate 8 the plunger 18 beingthen in-registry witlrthelockingrecess I9-formed in the tang II is caused to enter this recess by the spring 22 and the door is thusretained in the open position untilthe plunger I 8- is withdrawn from the recess I 9. Thismay be done by grasping the handle I8 whereupon the door may again be closed either partly or entirely. If it is desired to render the automatic locking mechanism inoperative this may be done by turning the plunger I8 to cause the pins 21 to rest within the notches or niches formed in the head of the bushing 25, whereupon the door can be opened to its full extent without the automatic locking mechanism coming into operation. As above indicated, the shock absorbing mechanism cooperatively functions with the stop lug I5, the automatic locking mechanism including the plunger I8 and the strain or force transmitting means 43, 44, id to prevent undue strains and wear being placed thereupon by careless or inconsiderate door operators. For example, if it is attempted to open the door to a wider extent than that provided by the mechanism including the stop lug I5 the bar I is yiel-dingly extended in length, the spring 58 being compressed between the collar and pin 59 and 60 and the shoulder 54 formed by the bushing 54; and if it is attempted to close the door while the door is automatically locked in the open position the mechanism similarly yields under the influence of the spring mechanism, the spring 58 being then compressed between the shoulder 56' formed by the reduced parts 56 and 51 and the collar 59 which is prevented from movement by engaging the end of the sleeve 63, the pin 60 moving in the grooves 64 of the sleeve. This shock absorbing and yielding mechanism which forms a part of the arms-or bars, therefore, cooperatively functions with the locking means and the strain transmitting means 43, 44, 44 to protect the door holder against injury from rough and careless usage and minimizes the Wear thereupon. Moreover, as above indicated, the holder is readily adaptable to either a right or left hand door with no modification in construction thereof needed and with the single automatic locking mechanism equally operative in both adaptations to function with the shock absorbing means and the strain transmitting means above described as forming a part thereof. For example, while in the particular embodiment illustrated in Fig. 1 the door in opening swings counter-clockwise about its hinge 6 the mechanism is equally applicable to a door opening by turning about its hinge in a clockwise direction. Fig. 6 shows in full lines the application shown in Fig. 1, while the dot and dash lines show the relation of the bar 2 with respect to the bracket I in the other application referred to. Moreover, as above indicated, the adaptation from one character of door to the other is accomplished by disconnecting the bar 2 from the bar I and from the bracket I, turning it about its length through an angle of 180 so as to reverse its top and bottom faces and then securing it again to the bar I and the bracket 1, the bracket 1 being still secured to the door with the automatic looking mechanism depending from the under side of the bracket, while the automatic locking mechanism,- the strain transmitting means at the juncture of the bars I and 2 and the shock absorbing means forming a part thereof, function in the same advantageous manner in either adaptation of the holder. In the limiting position, namely, with the stop I 5 in engagement with the plate 8, the restrainingarms I and 2 are still oil the dead center, namely, they are disposed at an angle of less than 180 on the closing side or next to the hinge 6, and accordingly the door may be readily closed when the locking plunger I8 is withdrawn.
