r 3 Claims.

The invention relates to window operators and refers more particularly to operators for casement windows, storm windows, and the like.

The invention has for one of its objects to provide an improved window operator which is simple in construction and economical to'manufacture. a

The invention has for another object to so construct the window operator thatit may be readily reversed or turned upside down to alternatively mount the window operator in different zones of the window opening and to adapt the window operator for use with casement windows and the like hung at different sides.

The invention has for further objects to so construct the window operator that the handle for actuating the actuator arm is mounted to move transversely ofthe arm between predetermined positions; that the actuatin handle is operatively connected to the operator arm in a manner to relieve the device for securing the actuating handle to the operator arm from stress when the operator arm is being moved; and that the operator arm is automatically locked in the normal position of the actuating handle.

With these and other objects in view, the invention resides in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.

Figures 13 and 14 are cross sections on the lines l3-I3 and I4-l4, respectively, of Figure 12.

The operator of Figures 1 to 7, inclusive, is, as

illustrated particularly in Figures 1, 2 and 3, ap-

plied to a casement window comprising theframe I in the window opening and the side-hung ventilator 2. Both the frame and ventilator are of standard construction havingZ-bars with the against the plates.

inside and outside flanges 3 and 4 of the ventilator contacting with the inside and outside flanges 5 and 6, respectively, of the frame when the ventilator is closed.

' The operator, in general, comprises the support I mounted on the bottom bar of the frame I, the arm8 movably mounted on the support and operatively connected to the bottom bar of the ventilator 2 and the handle 9 operatively connected to the arm to swing the same to thereby open and close the ventilator.

The support 1 is in the nature of a horizontal housing preferably formed in one piece and extending transversely of the inside flange 5 of the bottom bar of the frame I.

prises the spaced upper and lower like plates I0 The support comand II which are approximately semi-circular and have in their peripheries the corresponding arcuate' series of open-ended locking recesses II. The support also comprises the foot flanges l3 at the corners of and connecting the plates Ill and H and preferably extending therebeyond. The support is secured to the inside flange 5 by suitable means, such as the screws [4 which extending through the foot flanges and are threaded into the inside flange. t

The arm 8 comprises the plate portion 15 and the arm portion l6 preferably integral with the plate portion. The plate portion is approximately circular and extends through the opening I'I in the inside flange 5 and between the upper and lower plates wand ll of the support and is pivotally mounted on and coaxial with the plates and also coaxial with the arcuate series of locking recesses. As shown, the pivot is in the nature of a hollow rivet l8 extendin through the plates and plate portion and turned over at its ends The plate portion has the projection 19 which extends laterally beyond the plates 10 and l I. The arm is provided with the opening 28 located partly in the plate portion and partly in the projection, the inner end of the opening corresponding in shape to a locking recess I2 andbeing adapted to register therewith. The arm portion I5 has secured to its free end the headed rivet 2| for slidably engaging the guide 22 which is fixedlysecured to the lower side of the web of the bottom bar of the venti- 1ator,'the arm in the closed position of the ventilator being in the space formed by the bottom bars of the frame and ventilator and also being substantially parallel to the bottom bar of the ventilator.

The handle 9 is formed with the attachment portion 23which is secured to the projection l9 and the grip 24 laterally beyond the projection. The attachment portion is channel-shaped and has the web 25 above the projection, the side flanges 26 extending over and engageable with the edges of the projection, and the inturned flanges 2'! extending from the lower edges of the side flanges and extending beneath the projection. The inturned flanges preferably'div erge with respect to the web laterally toward the support I so that their inner ends are spaced from the web a greater distance than their outer ends to pro-' vide for movement of the handle vertically-or transversely of the support. The handle is secured from accidental disengagement from the projection by suitable means, such as the screw 28 having the head 29 loosely engaging the hole" portion of the web 25 near the support 1 and has the vertically offset nose 34 and the intermediate portion 35. The nose has a shape corresponding to that of the locking recesses l2 and is adapted to engage one of the recesses or the opening 20 in the arm. The intermediate porr tion 35 preferably extends through a notch 36 in the end of the web near the support 1 to hold the nose from rotation relative to the handle. The nose is vertically offset from the hub portion so that the upper surface of the nose is substantially flush with the lower surface of the web 25.

The inturned flanges 2'! and the web cooperate to limit the movement of the handle 9 upon the projection IQ of the arm 8. The spacing of the inturned flanges from the web is such that when the inner ends of the flanges engage the lower surface of the projection I9 the nose is substantially in the plane of the upper plate [0 and engages one of its locking recesses l2. when the inner end of the web 25 is in contact with the upper surface of the projection the nose is in the plane of the plate portion l5-and projection l9 and engages the opening 20, at which time the nose clears both plates l0 and II of the However,

in its normal position the grip is in its lowermost position and the nose of the locking dog is in its uppermost position and engaging the registering locking recess of the upper plate of the support. At this time the operator is locked to hold the ventilator from swinging movement. However, by raising the grip of the handle, it is apparent that the nose of the locking dog will be moved to a position clearing both the upper and lower plates of the support to permit swinging the operator arm to thereby swing the ventilator.

The above construction of operator is such that it may be readily reversed or turned upside down to permit mounting the operator in different zones of the window opening and to adapt the operator for use with casement windows and'the like hung at diiferent sides. For example, if it is desired to use the operator with a casement window hung at the side opposite that of Figure 1, the handle 9 may be readily disconnected from the arm 8 by removing the screw 28, the rivet 2| may be disconnected from the arm portion l6, and the support I and arm 8 may be readily reversed or turned upside down as a unit. The handle may then be reversedor turned upside down and mounted on the arm and connected thereto in proper position and the rivet may be secured to the'opposite side of the arm portion, the handle and rivet at this time occupying positions reverse to those shown in Figure 1.

In the modification illustrated in Figure 8, the construction and the operation of the operator are-the same, in general, as the construction and operation of the operator in Figures 1 to '7, inclusive. However, the operator of Figure 8 differs essentially in forming the locking dog 31 integral with thehandle and in providing the coil spring 38 for resiliently holding the grip of the handle in its lowermost position and the nose of the lockingdog in the plane of and engaging one of the locking recesses in the upper plate 39 of the operator support. To provide for the coil spring the upper surface of the extension of the operator arm has the recess 4| for receivingthe lower end of the coil spring and the web of the attachment portion of the handle is formed with the upwardly extending boss 42for receiving the upper end portion of the coil spring.

Figure 9 discloses another modification in which the spring 43 formed of flat stock is used to resiliently hold the locking dog in normal position. This spring has the flat body 44 which is secured to the upper side of the projection 45 of the arm by the head of the screw 46. The spring also has theinclined end portion 41 bearing upon the lower side of the-nose 48 of the locking dog to normally hold the same in its uppermost position as determined by engagement of the inner ends of the inturnedflanges 49 of the handle attachmentportion with the lower face of the projection 45.

Figures 10 and 11 disclose anothermodification in which the handle 50 has the grip 5| and the attachment portion 52, the latter being provided with the locking. dog 53 for engaging a locking recess in the upper plate of the support, which latter is formed in the same manner as the supports previously described. 54 is a bowed spring preferably formed of flat stock having the flat portion 55 fixedly secured to the upper face of the projection 56- of the operator arm by the head of the screw 51. The bowed portion 58 of the spring is engageable with the lower face of the grip 5| to resiliently hold the latter in its uppermost position as determined by the inner end'of the web 59 of the attachment portion of the handle engaging the upper side of the projection 56. At this time the-locking dog engages a locking recess. To release the operator, the grip 5| of the handle is swung to it'slowermost position, as determined by the inner ends of the inturned flanges 59' engaging the projection 56, at which time the nose of thelocking dog is located above and clears the upper plate of the support. It will be noted that the projection 56at its free corner has the struck-up portions 60, the inner edges of which serve with .the screw to hold the spring 54 from rotation horizontally of the projection. Also, that. the struck-up portions serve as fulcrums for the handle to avoid abrupt bending of thespring.

Figures 12;"13and 14 show another operator in which support 6| is formed in substantially the same manner as the supports previously described. More specifically, the support 6| has the spaced upper and lower plates 62 and 63, respectively, which are alike and which have in their peripheries the corresponding arcuate series of open-ended locking recesses 64. The operator arm 65 is formed in the same manner as the arms previously described with the approximately circular plate portion 66 and the arm portion 61, the plate portion having the projection 68 extending laterally beyond the plates. The plate portion extends between the plates and is coaxially pivotally secured thereto by the hollow rivet 69 which is internally threaded. The handle 10 has the attachment portion II and the grip 12. The attachment portion has the arm 13 extending over the upper plate 62 and pivotally secured to the support by suitable means, such as the screw 14 threaded into the rivet. The attachment portion also has the integral depending channel-shaped portion 15 embracing the projection 68 for swinging the operator arm. The handle is movable vertically or transversely of the support GI and the upward movement of the handle is limited by the transverse wall I6 upon the channel-shaped portion 15 engageable with the lower face of the projection 68. The locking dog 11 is integral with the attachment portion and is located so that in the normal gravity operated position of the handle the locking dog engages one of the locking recesses 64 in the upper plate 62 of the support. The location of the locking dog is also such that when the grip of the handle has been raised to a position as determined by the wall 16 engaging the projection 68, the locking dog is positioned above and clears the upper plate of the support so that the handle may be swung to swing the operator arm.
