Application June 1, 1937, Serial No. 145,656 g ‘ 2 Claims. (01. 268-419) The present invention relates to actuators for hinged closures. Swinging closures, such as French windowshatchway covers, screens, ven tilator lifts, and like structures usually have 5 actuators for manipulating them so that the clo sures may be readily and easily moved to ad justed position. It has been found from experience that some times French windows and like closures are so heavy that they become warped, whereupon it is impossible to eifect closing tightly enough to exelude rain, snow, sleet and the like. Actuators for such closures are‘ used at the present time, but none is capable of ready adjustment to effect and partially in plan, taken substantially in the plane indicated by the line VII—VII of Figure 8. Figure 8 is a vertical sectional View showing a modi?ed construction of certain of the parts. Figure 9 is a fragmental vertical sectional view, O1 taken substantially in the plane indicated by the line IX—IX of Figure 1. Figure 10 is a fragmental vertical sectional view, taken substantially in the plane indicated bythe line X-~X of Figure 1. 10 Figure 11 is a fragmental vertical sectional view, taken substantially in the plane indicated by the line XI-XI of Figure 4. 15. tight closing or sealing when the closures are The drawings will now be explained. In Figures 1, 2 and 3, the invention is exempli An object of the present invention is to pro vide actuators for hinged closures, which actu ators will effect tight sealing orclosing when the 2,0 closures are slightly warped. Another object of the present invention is to A frame is indicated at A with the window or sash indicated generally at B. The sash or clo sure member B is hingedly connected to the frame A by hinges I and is adapted to be opened upwardly as viewed in Figures 2 and 3. The sash warped. ?ed in a hinged closure, such as a French window. provide an actuator for a hinged closure which, in themain, may be manufactured of stamped parts. 25 Another object of the present invention is to ' provide an actuator for the lid of a trailer venti lator, which actuator is economical to manufac ture and highly ef?cient in'use. The above, other and further objects of the 30 present invention will be apparent from the fol " lowing description and accompanying drawings. The accompanying drawings illustrate embodi ments of the present invention, and the views thereof are as follows: 35 Figure 1 is a fragmental elevational view of a hinged closure, equipped with an actuator con structed in accordance with the principles of the present invention. . Figure 2 is a fragmental horizontal sectional 40 view taken substantially in the plane indicated by the line II—II of Figure 1. Figure 3 is a fragmental horizontal sectional , view taken substantially in the plane indicated by the line lI[I—III of Figure 1. 45 Figure 4 is a vertical sectional view through a trailer ventilator equipped with an actuator con structed in accordance with the principles of the present invention. Figure 5 is a vertical fragmental sectional view, 50 with parts in elevation, taken substantially in the plane indicated by the line V-—V of Figure 3. Figure 6 is a View, partially in horizontal sec tion and partially in plan, taken substantially in the plane indicated by the line VI-—VI of Figure 5. Figure 7 is a View, partially in horizontal section 55 or closure member B is illustrated as a window carrying a pane or glass C‘, with top and bottom sash rails 2 and 3 respectively, vconnected at their ends to stiles 4 and 5. The actuator illustrated in Figures 1, 2, 3, 5 and 6 includes a stamped plate 6 havinga horizontal ?ange l for attachment to the sill of the frame and a vertical ?ange 8 attachable to the upright member of the frame, by screws or other suit able attaching means. Between the horizontal portion of the plate 6 and the vertical ?ange 8, and between the side margins of the plate, it is cut away forming an opening 9, in which is rotat 30' ably mounted a worm Ill. The worm I0 is keyed 35 or otherwise fastened to a sleeve II which is of greater length than the worm, projecting from both ends of the worm, as may be observed in Figure 6. A supplemental plate I2 is fashioned with ears gs 0 which are bent around the extending end por tions of the sleeve II to- secure the sleeve and worm in position in the plate 6. These portions which are bent around the extremities of the sleeve ll form bearings l3 for the sleeve and worm. Between. the horizontal portion of the plate 6 and the vertical flange 8, the plate is curved downwardly at I4, as shown in Figure 1, to receive portions of the bearings I3 for the sleeve II. The worm Ill is thus supported in the plate with its axis in horizontal position and closely adjacent the portion. of the frame A to which the vertical ?ange 8 of the plate is at tached. The horizontal portion of the plate 6 is aper 55. 9 2,122,570 the frame A in parallel relationship to the hinge integral portions of the crank which are laterally spaced from the side margins of the lever 31. The lever 31' is provided with upstanding ears 44 and 45 which constitute stops. Threaded into connections of the sash or closure member Bv to the ears 42 and 43 are screws or bolts 46 and 4-1, the frame A. which may be adjusted towards and away from the cars 44 and 45 of the lever to position the lever in desired angular relationship with respect to the crank 36, and also to afford driving con 1O nection between the crank and the lever. The sleeve H which drives the worm II] is fashioned with a polygonal interior Ha (Figure 6) to receive the correspondingly shaped end of a removable crank 49. Preferably, the polygonal interior i Id of the sleeve is disposed at the inner 15 end of the sleeve in spaced relationship to the tured at “5, the supplemental plate l2 being aper tured to register therewith, for receiving the lower end of a vertical shaft 25 which is supported in A stamped gear I‘! having teeth i8 for meshing with the worm I0 is pivoted on the shaft i5. The gear I? is incomplete as far as its peripheral portion is concerned, and has 143' a tail'extension 18a. . A lever 19 is apertured to surround the shaft I5 and rest on top of a portion of the gear I‘! and its tail portion laa. The lever I9 is opera tively connected to the tail portion l8? of the gear by means of a screw 20 passing through an 31 aperture in the lever and threaded into the tail 18%, ,thus connecting together the gear and the . entrance end thereof, to prevent ready insertion lever for oscillating with the shaft. In order to of a tool for operating the actuator of the pres~ oscillate the shaft l5 in accordance with oscilla- ' ent invention to manipulate the sash from its tory movement imparted to the lever_.l9, any suitable driving connection may be employed. I The driving connection illustrated consists of two diametrically disposed slots 2| and 22 formed in the leveradjacent the shaft i5, and the shaft i5 is apertured to receive a pin 23 which lies in the slots 2| and 22. The pin 23, in addition to connecting the shaft l5 and lever l 9 together for oscillatory movement, supports the shaft in ver tical position with respect to the bracket 6. The upper end of the shaft I5 is supported by a stamped bearing including an attaching plate portion 24 and a barrel 25 which receive the upper end of the shaft. For a distance extending down wardly fromthe upper end of the shaft, the shaft is recessed at 26, to thereby provide a ?at sur face 21., Attached to the lower rail 3 of the sash B, is an elongated stamped metal ?anged member 28 arranged with its ?ange 29 parallel to and 11'. spacedfrom the raii 3. This member 28 is se cured to the lower rail of. the sash by means of screws 30 or other suitable fastening means. Pivoted to the free end of the lever i9 is a shoe 3| having a J-shaped formation to engage the opposite faces of the ?ange 29 of the member 28 and pass underneath the margin of the ?ange, as readily observed in Figure 10. The shoe 3| is pivoted to the free end of the lever I9 by means of a pin 32, so that play may occur be respect to the frame by inserting the crank 49 in the sleeve H, with the polygonal-shaped end of the crank engaging the interior Ila of the sleeve, whereupon rotation of the crank 49 in 25 clockwise direction, as viewed in Figure 1, will cause the sash B to be swung to opened position, that is, with its free margin swung upwardly, as viewed in Figures and 3. When the sash has been moved to desired position, the crank may be 30 withdrawn, whereupon the sash remains in this position until the crank is again applied and the worm rotated to move the gear I‘! in such direction as will move the sash to another ad justed position. It sometimes happens’ that hinged closures,‘ 35 such as screens, French windows, screen doors and the like, which are manipulated by actuators, warp or sag, which warping is especially notice able at the upper outer corner of the closure. When such warping occurs, it is well nigh impos sible to secure tight sealing between the closure and its frame. The provision of. the adjustment betweenthe upper lever 3‘! and the crank 36 takes care of such warping. 45 Assume that the upper outer corner of the sash B of Figure 1 had warped outwardly so that manipulation of the levers l9 and 31 would not. effect tight sealing of the closure against its tweenthe shoe and the lever when the shoe is moved back and forth along the ?ange 29 to swing the sash or closure member B to adjusted frame. position. upper outer end of the sash tightly against its frame, and thus overcome the effect of the warped condition of the sash. 55 The amount of adjustment of the lever 31 with Attached to the upper rail of the sash B is a similar member 33 having a ?ange 34 extending along and in spaced relation to the rail, as may be observed in Figure 9. This member 33 is secured by screws or like fastening means 35. Keyed or otherwise ?xedly secured to the upper 60 end of the shaft, a slight distance below the barrel 25 of the bearing member, is a crank 38 which projects along the upper rail of the sash for a short distance. An upper lever 31 is aper tured at one end as at 38 to surround the shaft 85 and to have movement relatively to the shaft. 1 The lever 37 carries at its free end a shoe 39, pivoted thereto by a pin 49. The shoe 39 has a hooded part 4! which engages over the upper margin of the ?ange 34 of the member 33 and bears against opposite sides of the ?ange, as the shoe is moved in use. Means are employed for connecting the crank 36 to the lever 31 in driving relationship. 75 adjusted position, by an unauthorized person. The sash B is moved to adjusted position with The means illustrated for accomplishing this purpose comprise upstandinglugs Hand 43 as In this event, the screws or bolts 46 and r 41 are manipulated as to so angularly adjust the lever with respect to the crank as to draw the respect to the crank 36 depends, of course, on the warped condition of the closure, which such ad justment is intended to overcome. The lever 31 and crank 36, in Figure 2, appear with the parts in normal position. If the closure member B is slightly warped, then the screw bolts 43 and 41 would be adjusted to move the left hand end of the lever, as viewed in this ?gure, a slight dis= tance below that shown in the ?gure, so that when the closure member is moved against the frame, added pull will be exerted by the shoe which engages the ?ange 34 of the member 33. Figures 7 and 8 illustrate a modi?cation wherein the upper lever 31 and the upper member 70 33 are eliminated, and instead of the utilization of theshaft l5, a pivot pin is employed. In this form of the invention, a stamped metal plate 48 is provided with spaced ?anges 49 and 50 for attachment to the sill 5| of a closure frame. 2,122,576 The central portion of the plate 48 lies above the ?anges 49? and 50. The central portion of the plate 48 is apertured at 52 to receive a pivot pin 53*, which pin has a head,54,,a cylindrical portion 55' to closely ?t within- the aperture 52, and an other cylindrical portion 56 of reduced diameter. This portion‘ of reduced diameter is counterbored‘ and threaded to receive a screw 51'. Surrounding the portion 56' of the pin- is a gear formed of. two- similar stamped sections 58! and 58'. The sections 58 and 58' are separately stamped‘ and then are brought together with their teeth in register and so held, and then cen trally bored to form the center opening for the 15 pivot. A horizontally disposed worm 59 is keyed or otherwise secured to a hollow sleeve 60, the ends of which are supported in apertured lugs 6! and 62 turned up from the material of which the plate 48 is made. The worm 59 is in mesh with the gear composed of the sections 58 and 58’ and designated generally at E. A lever 63 of stamped ?at metal is apertured to surround the pivot pin 53, surrounding the portion of reduced diameter 56 of the pin. The 25 lever 63 is secured to the gear D by means of rivets, bolts or like attaching means 64 which pass through the lever and sections 58 and 58’, thus connecting the gear and lever together for cooperative action. 30 For covering the worm 59 and sleeve 60, a cover plate of stamped metal 65 has a part overlying the gear D, a part overlying the worm, and a horizontal ?ange 66 which rests on top of the ?ange 58 of the plate 48. The cover plate is 35 held in position by screws 61 passing through it and the ?ange 56 of the plate 48 and entered in the sill 5| of the frame. The screw 51 passes through an aperture in the cover plate and is threaded into the pin 53. The hollow sleeve 60 40 which carries the worm 59 is provided with a polygonal portion 60' to receive the similarly shaped end of a crank, such as the crank 49, for rotating the worm to actuate the lever 63. This form of the invention is utilized in con 45 nection with a hinged closure, where but one lever is su?icient to- operate the closure. In Figures 4 and 11, there is illustrated an exempli?cation of the application of an actuator of the present invention to the lift of a trailer 50 ventilator. As usually constructed, trailers are provided with ventilators in their roofs which, when opened, permit circulation of air from the interior of the trailer to the outside. The problem of closing such ventilators, as regards 55 weather conditions, is important. It is neces sary to effectively seal such ventilator openings to prevent entry of rain, snow and wind to the interior of the trailer. In this form of the invention, 68 represents 60 a wall built around the ventilator opening in the roof of a trailer. Hinged at 68 to the wall is a lid or hinged closure 16 adapted to be moved on in a direction away from the worm. Movable about the pivot 80 is a lever 83 which is con nected to the tail 82 of the gear by means of a rivet 84, thus connecting the lever and ‘gear in operative relationship. Carried at the free end of the lever 83 is a shoe 84 having a part engag ing opposite surfaces of the ?ange 12 of the mem ber TI‘. The shoe 84 is pivoted to the lever 83 by a suitable pin 85 so that relative rocking movement may occur between the lever and the shoe, as the closure member 18 is moved about its’ hinged connection to the wall 68. For manipulating the closure member or lid "ill, the shaft 18 is provided with a hand wheel 86 disposed near the roof of the trailer and which 15 may be readily manipulated from the interior of the trailer. To open the lid or closure mem ber 70, the hand wheel 86 is turned to the right, whereupon the free end of the lever 83 rises and opens the lid 10 about its hinges. To close, the 20 hand wheel is rotated in the opposite direction, the shoe 84 cooperating with the frame 12 to close the lid against the wall 68. By reason of the construction illustrated and described, the lid or closure may be tightened 25 against the wall 68 in sealing relation, by giving the hand wheel 86 an additional turn to the left after the closure has been seated, whereupon a squeezing effect takes place between the closure and the wall. If desired, suitable gasket means might be secured to the margin of the wall for engagement by the lid when it is in closed posi tion, as an added means for preventing ingress of rain, snow and sleet. It will be observed that the actuator of the = present invention is one which, in the main, may be manufactured by stampings, as all of the parts, except the worm, the crank and the worm mounting sleeve, may be stamped from suitable metal, thus reducing the cost of manufacture of the actuator. The manner of assembly is simple and can be carried out at minimum expense for labor. The actuator herein described has proved very eflicient in use, and as made is rugged and sturdy 45 to withstand all abuse to which such a device may be put in service. The provision of two levers applied to the top and bottom rails of a large and heavy closure is an advantage because of the fact that the upper lever may be so adjusted as 50 to effect tight sealing of the closure against the frame, should the closure be warped. The invention has been described herein more or less precisely as to details, yet it is to be under stood that the invention is not to be limited 55 thereby, as changes may be made in the arrange ment and proportion of parts, and equivalents may be substituted, without departing from the spirit and scope of the invention. The invention is claimed as follows: 1. In a device of the class described, a frame, a closure hinged to said frame to swing, a bar of its hinge to adjusted position. Attached to the angular section attached by a flange to said clo underside of the lid or closure 16 is an elongated sure and having a web normal to said closure and another ?ange parallel to and spaced from ‘ the closure, a slide formed of sheet metal shaped to provide a U-head to ?t about said other ?ange flanged member ‘ll having a ?ange ‘l2 spaced from the lid 16.
