6 Claims. (o1. 26S-111) Our invention relates to improvements in window and door adjusting and holding mechanism -of the general type disclosed in a co-pending application, led by John G. Shodron, Serial No. 344,641, led-March 6, 1929.

Objects of this invention4 are to provide im- Aproved means for utilizing crank operated connections for opening windows or doors, particuv larly windows or doors which are hinged along their upper margins and opened by swinging them to oblique positions with reference to the relatively xed frame or wall of the building; also, to provide means for locking or securely holding the closure (door or window) in various open positions, and in the closed position; also, to pro- Vide means for simultaneously actuating a door 'or window by pressure applied adjacent to both side margins and securely holding it in the ad- I justed position by means ofthe actuating connections, such connections being simultaneously operable from a single crank or actuating member located either centrally or at one side of the opening.

p to the brackets at 18. The two cranks illustrated are connected with each other by a bar 19 which 4is formedof resilient material. The ends of this bar are preferably elbowed and riveted to the cranks in reinforcing relation thereto. The extremities of the elbowed arms 20 being preferably apertured to receive the pivot pins '18'. 1`

Near their outer ends the cranks 15 areprovided with brackets 22, U-shaped brackets being preferably employed, and provided with vthreaded apertures to receive the r'threaded ends ofv connecting rods 23. The brackets 22 are s'wive'lled to the cranks, the central portion of each bracket being connected withits associated crank by a rivet or bolt 25, upon or with which the bracket may rotate.

The connecting rods 23 have elbowed ends 2'8 which extend through apertured ears 29, to which they are secured by cross pins or cotter pins 30.

These ears 29 are connected with the sash frame It will be observed that by swinging either ofthe cranks 15, motion will in any suitable manner.

sill 16 with a toothed sector bracket 32, so located K that its arcuate toothed portion will be inthe" normal path of the central portion of the cross bar 19 when said bar swings in association with the cranks. The spacing between the teeth 33 of the sector is such that the bar'19 will be received between theteeth, and the bar is preferably rec" tangular in cross section and of a width to snugly fit between the teeth 33. When the bar is in position between two teeth 33 of the sector, the sash will, of course, be securely locked against "movement u-pon its hinges, and 'both side margins will be held with equal security' against movement under wind pressure or any other force that may be exertedagainst the sash.

But when it is desired to change the adjustment of the sash, the engaging portion of the barY 19 l:

may be sprung outwardly to a sufcient' Aextent to release it from between the teeth 33, whereupon the bar may be raised or lowered and its motion transmitted to the cranks to open or lclose the window, or adjust it to a different open -posi- I tion. 'I'he bar 19 has sufficient resilient tension so that, when released, it will spring into sector engaging position if in registry with one of the notches between the teeth 33. If the bar should be carelessly left in engagement with one of the teeth it will automatically engage in an adjacent notch as soon as the window commences to move under pressure of the wind or otherwise.

In Figures 3 to 7, inclusive, we have illustrated a modified form of construction in which parts similar to those illustrated in Figures l and 2 are identified by the same reference characters with the letter a added. In these views the window frame and sash are substantially like those disclosed in Figures 1 and 2, and no further description, thereof, will be necessary. The cranks 15a are pivoted to brackets 17a by the pivot pins or bolts 18a in a manner similar to that disclosed in Figures 1 and 2, but one of the brackets 17a is provided with a toothed sector 32a, and the associated crank has an arm V40 to which a locking dog 41 is pivotally secured at 42. The locking dog 41 is of bell crank type with one arm 43 disposed for engagement between teeth 33 a of the sector 32a. The other arm of the dog extends over the crank arm 40 and is normally in spaced relation thereto, with an interposed spring 45, the ends of which are engaged with seating studs 46 and 47, carried by the dog and the arm 40, respectively. This arm 40 constitutes a convenient means for connecting the cross bar 19a, through .which motion is transmitted to the crank 15a at the opposite side of the window casing. The arms 43 of the locking dogs swing into locking relation to the sector 32a with their intermediate portions between a pair of ears 49, carried by the associated crank 15a. These ears relieve the arms 43 and pivot pin 42 from excessive strains which would otherwise be exerted by the wind when the window is held in its open or partially open position.

The connecting rods 23a may be secured to the window sash in the same manner as described with reference to Figures l and 2. They may be secured to the crank 15a by a coupling 22a connected with the crank by a pivot pin or bolt 25a, the connecting rod being screwed into the coupling 22a. The latter is suitably socketed to receive it, as clearly shown in Figure 7.

In this modied form of construction, the toothed sector 32a will be located in association with one of the crank arms, and will, of course, be omitted from the bracket 17a associated with they other crank arm. Also, only one of the cranks 15a. will be provided with a locking dog or pawl 41.

We claim:

1. The combination with a swinging closure of window or door type, of a relatively xed support, a set of cranks pivoted thereto and respectively linked to the middle portions of the sides of the closure a resilient cross bar connecting, said cranks with each other for simultaneous operation, a toothed sector secured to the frame opposite the middle portion of said bar and adapted to'normally receive the bar between its teeth for locking the cranks in various positions of adjustment Vto hold the closure in corresponding positions of open or closed adjustment.

2. The combination with a swinging closure of window or door type, of a relatively fixed support, a set of cranks pivoted thereto, linkage between the cranks and the sides of the closure brackets secured to the cranks in threaded engagement with said linkage to permit adjustment of the latter therein, a bar connecting thecranks and means connected with the fixed support for engaging the bar in the various positions to which it may be swung by means of the cranks.

3. The combination with a swinging closure of window or door type, of a relatively xed support, a set of cranks pivoted thereto, adjustable linkage between the cranks and the sides of the closure, a bar connecting the cranks and having a resiliently yielding portion, and an arcuately curved toothed sector connected with the support and disposed with its teeth in position for engagement with the resiliently yielding portion of the bar when the yielding portion of such bar is in normal position, said portion of the bar being manually retractible under pressure to release it from said teeth preparatory to re-adjustment of the cranks.

4. The combination with a swinging closure of window or door type, of a relatively fixed support, a set of cranks pivoted thereto and linked to the respective sides of the closure, a cross bar connecting said cranks and adapted to serve as a handle to operate the latter, a relatively xed toothed sector associated with one of the cranks, a dog pivotally associated with the cross bar and adapted to be engaged between the teeth of said sector, said dog having an operating handle ex'- tending along the cross bar to be gripped for dog retraction when the cross bar is being used as a handle to operate the cranks, and a spring for normally urging the dog to sector engaging position.

5. The combination with a swinging closure of window or door type, of a relatively fixed support,

a set of cranks pivoted thereto and linked to the respective sides of the closure, a cross bar con'- necting said cranks and adapted to serve as a handle to operate the latter, a relatively fixed toothed sector associated with one of the cranks, a dog pivotally associated with the cross bar and adapted to be engaged between the teeth of said sector, said dog having an operating handle extending along the cross bar to be gripped for dog retraction when the cross bar is being used as a handle to operate the cranks, and a spring for A normally urging the dog to sector engaging position, the associated crank being provided with ears between which the dog may engage when also engaged between the teeth of said sector.

6. The combination with a swinging closure of window or door type, of a frame to which one margin of the closure is connected for pivotal swinging movements, a relatively fixed support at the side of the frame opposite said pivotal connection, a set of cranksk pivoted to the support,
