Buchach, Milwaukee, Wis., assignor to Howard Safety Window, Inc., Milwaukee, Wis., a corporation of Wisconsin Application December 30, 1935, Serial No. 56,734 4 Claims. This invention appertains to window construc tions of the type wherein the sliding sashes are arranged to be swung inwardly relative to their window frame for ventilating purposes and to facilitate cleaning both sides of the glass panes of the sashes. (C1. 20—49) the sash guides and for eliminating objection able click as the catches and latches ride past the grooves in the guides. A further object of my invention is the pro vision of means for detachably and pivotally con 5 necting the sashes with the slide plates, whereby The present invention generally seeks to im- ' ease of operation of the swinging sashes is as prove that form of window shown in my prior Patent No. 2,038,266, issued to me April 21, 1936, it) whereby a durable, e?icient, and fool-proof win dow will be had, which will be easy to operate by the ordinary housewife, and which will be acceptable to the trade both from a manufac turing and installation standpoint. Another primary object of my invention is to improve the construction of ?xtures for sliding _ and swinging window sashes, whereby the use of springs and other complicated mechanism which ‘20 might be subjected to undue wear and break age, is eliminated, and whereby ease of operation is insured.‘ Another object of my invention is to provide sured without danger of accidental displacement of the sashes from the slide plates. With these and other objects in view, the in 10 vention consists in the novel construction, ar rangement, and formation of parts, as will be hereinafter more speci?cally described, claimed, and illustrated in the accompanying drawings, in which drawings: Figure 1 is a longitudinal section through a window constructed in accordance with my in vention, showing the sashes in dotted lines in their fully swung-open position to facilitate the cleaning of the glass panes thereof. Figure 2 is an enlarged, fragmentary, front ele vation of a window constructed in accordance improved ?xtures for sliding and swinging sashes, with my invention, with the bottom sash in its whereby an ordinary window can be readily con 25 verted into a combined sliding and swinging partially raised position ready to be swung into window. I ' Another important object of my invention is to provide novel means for forming the tracks and weather strip stops for the upper and lower 30 sashes, whereby the same can be folded from a single strip or piece of sheet metal. A further object of my invention is to provide novel slide members mounted in the channels of the side guides for pivotally supporting the sashes, with novel sash cord-operated catches for engaging in grooves formed in the edges of the tracks and window frame, when the sashes are in a predetermined raised position and swung into a room, so that accidental sliding movement 4O of the sashes is prevented. A further salient object of my invention is the provision of manually operated latches carried by‘ the sashes adapted to move through said grooves when said latches are actuated, to, permit 45 the swinging of the sashes into their vertical or angular positions, the latches providing auto matic means for releasing the catches when the sashes are in their vertical planes, to permit in 50 tentional raising and lowering of the sashes. A further important object of my invention is the provision of wear and stop guide plates car ried by the slide plates for the sashes arranged adjacent to the swinging sash cord-operated catches for partially engaging the manually oper 55 able sash latches, so as to reduce undue wear on 20 a room. a - 25 - Figure 3 is a longitudinal section taken on the line 3—-3 of Figure 2 looking in the direction of the arrows, with the view contracted and the intermediate part of the sash and frame elim inated, the ?gure illustrating one form of manu 30 ally operated sash latch and one form of hingedly ‘ connecting the sash with a slide plate. Figure 4 is a fragmentary edge elevation of a window sash showing the manually operated latch carried thereby. 35 Figure 5 is an enlarged fragmentary view look- ‘ ing toward the face of one of the novel guide pieces, with the slide plate therein and held against movement by the sash cord-actuated catch, the sash being in its swung-open position. .Figure 6 is a detail section through the bot tom of a sash similar to the lower part of Figure 3, illustrating another form of means for piv otally and detachably connecting the sash to a slide plate. ‘ 45 Figure '7 is an enlarged, transverse, sectional view through one of the novel tracks and weather, strip stops for the sashes, a part of one of the slide plates and its associate mechanism being shown in one of the channels of the guide, the slide plate and its associated mechanism being of a modi?ed form, the section through the slide plate and its associate mechanism being taken substantiallyon the line 1---‘! of Figure 8 looking in the direction of the arrows. ‘ 2 2,119,199 Figure 8 is an enlarged fragmentary view of one of the guide tracks and weather strip stops, illustrating the novel wear and guide plate for the latch and sash catches connected with the slide plate, the latch for the sashes being shown in cross-section.

Figure 12 is a detail fragmentary view taken on the line l2--l2 of Figure 11, looking in the direction of the arrows, showing the rigid latch lug. Referring to the drawings in detail, wherein similar reference characters designate corre sponding parts throughout the several views, the letter F generally indicates a window frame for the sliding and swinging top and bottom sashes 25 Ill and H. The window frame is of the ordinary construction and includes the side stiles I2, the lintel l3, and the sill l4. 30 35 40 4.5 Secured to the inner faces of the stiles I2 are my novel guides and weather strip stops l5 for the sliding and swinging sashes. In my patent heretofore mentioned, the tracks and weather strip stop beads for the sashes were of an integral structure and extruded, and in the present construction, the same are preferably formed from a single strip of sheet metal bent and folded into the desired shape. Thus, the metal is folded to provide channels "5 and I‘! for the upper and lower sashes l0‘ and H connected together by integral web 18, the sides of which ex tend beyond the adjacent walls of the channels to form ?anges l9 and 26. One side wall of the channel I‘! below the flange 20 is folded to pro vide a guide ?ange 21 for the channel, and the opposite wall of this channel is bent in to form the opposite guide ?ange 22. The wall of the channel l6 opposite the ?ange I9 is folded inter mediate its ends to provide a guide ?ange 23, and the extreme outer edge of this wall is' bent inwardly, as at 24, to form the bead or stop 50 for the sash-carried weather strip. 55 60 65 70 neck entrances, I can provide slotted bearing grooves 32, as shown in Figure 6 of the drawings, and thus round pivot pins 33 can be carried by the slide plates 25 and 26 and slipped directly in the grooves from any position. In order to hold the round pivot pins in place 10 machine screws 34 can be threaded into the cast Figure 10 is an enlarged, fragmentary hori 10 zontal section taken through the window on the 20 sashes can be entirely disconnected from the slide plate. This forms a convenient means for as sembling the sashes in the window frames. In lieu of utilizing ?attened pins and restricted with the heads thereof overlying the pivot pins. This reduces all hazard of the sashes being acci dentally disconnected from the slide plates by a 15 housewife. The side edges of both sashes have rigidly secured thereto metal wear strips 35, which are adapted to ?t closely against the slide plates 25 and 26 when the sashes are in their vertical positions. The sashes and the slide plates can be balanced in any preferred manner, and in the present in stance I have illustrated sash cords 36 and 31 for the upper and lower sashes respectively, and these cords can be trained over suitable pulleys 25 (not shown) and their outer ends provided with the window weights. The inner ends of the sash cords 36 and 31 are provided with eyes 38, into which are adapted to be placed the bills of hooks 39. These hooks 39 are associated with the slide 30 plates in a novel manner, which will be later de scribed. Referring back to the window frame, it will be noted that the inner faces of the stiles are pro vided with outwardly ?ared guide grooves 40, the inner restricted ends of which communicate with notches 4| formed in the ?anges 22 and the side walls of sheet metal guides. The walls of the grooves 40 carry any preferred type of metal wear plates 41!)’, which also function to give a ?nished 40 appearance to the frame. The grooves 40 and 4| are provided for the lower sash, as will be later described, and the con~ necting portion l8 of the guides with its ?anges l9 and 20 are cut away to provide grooves 42. 45 These grooves are arranged above the grooves 40' and 4| and are provided for the upper sash, as will also be later described. , Both the upper and lower sashes are provided with novel latches for holding the sashes in an 50 upright position and against swinging movement. The ?anges l9 and 23 form a part of the chan nel [6, which acts as a guide for the slide plate All of these latches can be constructed in the 25 of the upper sash I0, while the ?anges 2| and . same manner, with the exception that the latches on one side of the sashes can be spring~pressed. 22 form a part of the channel ll, which func I Figures 2, 3, and 4, I have illustrated these tions as a guide for the slide plate 26 of the lower sash ll. ‘Obviously, this construction is latches, and it is to be noted that each latch in cludes a rigid latch lug 44 and a sliding latch duplicated on the other side of the window. _All of the slide plates 25 and 26 are provided with lug 45. The latch lug 45 extends through a slot 46 formed in the metal wear plate 35 on the side pads 21 which ?ll up the space between the inner walls of the channels and the ?anges 23, [9, 2|, of the sash, and the lug 45 is movable toward and 22. This prevents the sliding plates from and away from the rigid lug 44. rattling and prevents the creeping of air up the The sash edges are mortised or recessed in the rear of the wear plates 35 to receive a face plate channels. ' 41, which can either be secured to the woodwork The lower corners of the sashes l0 and II are of the sash or to the inner edge of the wear provided with castings or ?ttings 28 for the re ception of inwardly directed pivot pins 29 car plate 35. The rigid lug 44 can be anchored to ried by the lower ends of the slide plates 25 and or formed directly on the wear plate 35, as shown 26. As shown in Figures 1, 2, and 3, the pins 29 in Figure 12. can have ?attened sides to permit the sliding The movable or sliding latch lug 45 is carried thereof in the restricted neck entrances 30 of by a movable latch plate or bolt 48 arranged on the bearing openings 3|. ' the inner face of-the wear plate 35, and the same is provided with a longitudinal slot 48’ in which is When the window sashes are in a horizontal position, the pins 29 will register with the re placed a guide pin 49. v A coil spring 50 is placed stricted neck entrances and allow the sashes to 75 be pulled out of the bearing openings, so that‘the 55 60 65 70 in the slot'with its ends between the pin 49 and one Wall of the slot for urging the latch plate 48 75 3 2,119,199 downward, and the movable lug 45 away from the immovable lug,44.. An operating handle 5|~ ex tends out of the face plate 41 and beyond the front face of its sash, so that the same can be conveniently manipulated. Normally, the latch lugs 44 and 45 of the upper sash ride against the inner edge of the ?ange l9, and the lugs 44 and 45 of the lower sash normally ride against the inner edge of. the flange 22 to hold the upper and 10 lower sashes against outward swinging move ment. In order to swing open the sashes, the sashes are raised until their rigid lugs 44 register with the grooves 40, 4|, and 42, at which time the 15 handles 5| can be manipulated for moving the movable lugs 45 toward the rigid lugs 44, so as to lift the movable lugs into registration with the guide grooves. After the lugs have been raised, the lugs 44 and 45 can be moved through the grooves and the ‘sashes swung out. It is highly desirable to hold the slide plates 25 and 25 against movement when the sashes are in their swung-open position, and hence I have provided novel catches 52 for this purpose. These catches 52 are pivotally connected at their lower forward corners, by means of pivot pins 53, to the upper ends of the slide plates, and the upper forward ends of the catches are provided with laterally extending ears or detents 54. The hooks 39 for the sash cords have their lower ends connected by means of pivot pins 55 to the catches 52 at one side of the pivot pins 53, and hence the sash cords with their weights nor mally tend to swing the catches on the pivot pins 53, and the detents 54 toward the ?anges l9 or 22, as. the case may be. Thus, when the sashes are raised and swung to an open position, the de tents will be swung into the grooves 4| or 42, as the case may be. Obviously, this will effectively 40 hold the slide plates and the sashes against sliding. ' When the sashes are swung to a closed position, the lugs 44 and 45 will ride into the ?ared en~ trances of. the grooves 40 or 42, and the lug 45 will be moved toward the lug 44 by the lower wall of the groove. As the sashes reach their vertical positions the lugs will strike the detents 54 and swing the catches 52 back, and the de tents out of the grooves. This will allow slid 50 ing movement of the slide plates and sashes. When the lug 45 moves back to its normal position away from the rigid lug 44, entrance of the lugs into the grooves will be prevented. ‘In Figures '7, 8, and 9 I have shown a slightly modi?ed and preferred form of the window sash latches, and in this form rigid and movable lugs 56 and 51 are provided, and the inner edges: of they lugs overlap. The outer edges of the lugs are bent laterally to form stops 58. The sliding lug 60 5‘! is carried by a latch plate 59, which is actuated by a thumbpiece or handle 50. In order to prevent Wear on the metal guides and to eliminate objectionable click as the window latches ride past the notches, I provide a novel guide and wear plate 6|, which is clearly shown in Figure 8. This guide and'wear plate BI is rigidly secured by means of. pins 62, with the upper ends of the slide plates, and the bottom portions of the wear and guide plates lie on the 70 inner face of, the slide plates and are provided with outwardly extending right angular wear ?anges 63. As illustrated in Figures '7 and 8, the wear ?ange 53 rides against the inner edge of the 75 ?ange I9 or 22, as. the case maybe, and this ?ange 63'is so disposed as to form a stop for the swinging slide plate latches when the same are swung into the grooves. When the sashes are in their vertical positions with the movable latch lugs 51 away from the rigid latch lugs, the same lie between the catches of the slide plate and the inner face of. the wear and guide ?ange 63. Thus, the latch lugs do not engage the walls of the channels of the guide members, and hence do not click against the inner ends of the walls of the grooves. This is an important feature and facilitates the ease of raising and lowering the sashes. By referring to Figure 1, it will be noted that when the sashes are raised and then swung to 15 their extreme open position, the lower sash rests against the sill adjacent to its outer end, and the top sash rests on top of the lower sash. By this arrangement, an e?ective rest is formed for the sashes without imparting undue stress on the slide plates, and hence breakage of. the sashes and their ?xtures is eliminated. When the sashes are in their full open positions, the oppo site faces of the window panes can be easily cleaned. ‘ 25 The lower sash is also provided with a ventilat ing position, and to permit the same to be swung into such position, the inner faces of the stiles i2 of the window frame and the adjacent portion of the metal guides are grooved, as at 55. These grooves terminate short of the front edge of the window frame. ' When it is desired to ventilate a room without creating any draft, the lower sash is slightly lift ed, and when the sash latches are in correct posi tion relative to the groove 55 the movable lugs are actuated and the sash is swung forwardly with the lugs riding in said grooves. The lugs engaging the front walls of the grooves prevents further movement of the sash. The lower end of 40 the sash rests on the sill, and hence the entrance of the air into the room will be above the lower sash only. From the foregoing description it can be seen that I have provided a window of the combined 45 sliding and swinging sash type, which will oper ate efliciently under all conditions and which is substantially fool-proof. The wear plates 35 on the sides of the sashes. carry weather strips 65 formed of felt or the like, 50 which are adapted to engage under the ?anges 20 and 24 when the sashes are in their vertical position. . This is similar to the construction shown in my mentioned co-pending application. Changes in details may be made without de 55 parting from the spirit or the scope of this in vention, but what I claim as new is: 1.
