SASH MOVER AND LOCK-- Specification of Letters Patent.

Application filed Apri14,1906. Serial No. 263.788.

To all whom it may concern.-

Be it known that we, ALFRED REGINALD HARDY, accountant, and ROBERT "NOBLE ADAMS, publisher, of Dunedin, New Zealand, have invented certain new and useful Improvements in Sash Movers and Locks, of

. which the followin is a specification,

panying drawings, in which the same numerals of reference indicate the same or similar parts, and in which' Figure 1 is a front elevation of the apparatus, the u per sash 18, lower sash 19, architrave 27 pu ley-stile 43, and facing-board 45 bein shown in dotted lines in order to more clear y indicate the method of mounting the gearing and the means of operating the gearing to enable the upper and lower sashes to be operated independently or simultaneously. Fig. 2 is a side elevation of the apparatus, the

architrave being removed and a part of the upper sash 18 and lower sash 19 being shown in section in 7 order to more clearly show how the gearing of the apparatus engages with the toothed racks 14 and 15,secured to the side rails of said sashes'18 and 19. Fig. 3 is an enlarged view of a portion of Fig. 1 to show the method of actuating and locking the gearing. When the handle 34 is removed,

4 as shown in dotted lines, the key 31 is in the position represented by dotted hnes. Fig. 4

1s a perspective view of the locking-plate 2 2.

of end ln s 4 7 and 6 9 carry short spindles 1 and 3, w 'le'the middle air carry the long spindle 2. On said spindles 1, 2, and 3 are mounted the pinions 11, 12, and 13. The upper and lower pinions 11 and 13 are preferab y of the same size and engage in racks 14 and 15, respectively attached to the side-rails 16 and 17 of the upper and. lower sashes 18 and 19 of the window. To permit the pinions 11 and 13 to engage in the racks 14 and 15, clearance is provided in the pulley-stile 43 at 44. The middle pinion 12 is double the width of the other pinions 11 and 13 and is divided by a central flange 20, of greater diameter than the pinion 12, said flange 20 being for e of engaging in a slot 21, formed the puiggls in a 100 g-plate 22, (which locking-plate 22 is more particularly shown in Fig. 4.) Said locking-plate, which is ada ted to slide be tween the lugs 8 and 9 on t e face 23 of the base-plate 10, is provided with projecting pieces 24 and 25, which are of ashape suit+ able to engage in the s aces between the teeth of the pinions 1 1 an 13, for the purpose of locking either pinion to retain the corresponding sash in a fixed position when it is desired to operate the sashes independently. The spindle 2, to which the pinion 12 is secured,is adapted to slide laterally in the lugs 8 and 5 and has its outer end 26 projecting beyond the architrave 27. A slot 28 and a channel 29 are formed in said outer end 26 of said spindle 2, and said channel 29 is adapted to have a spiral spring 30 inserted therein. A key 31, having one of its ends in the slot 28 and pivoted thereto, is adapted to lie in the channel 29. .The spring 30 bears upward against the under face of the key, thus tending to force the key upwardly out of the channel. A locking-washer 32, which has a central hole 33 and a slot 34 therein, communicating with said hole, is secured to the architrave 27, so that its center is in line with the center of the spindle 2 in order that the end 26 of the spindle 2 may be revolved freely in the hole 33 by means of the handle 34.- After the handle 34 is in the position illustrated in Fig. 3 and the thumb-screw 35 is screwed home, securing said handle 34 to the spindle 2, the apparatus is unlocked and. in a condition to operate the sashes. Fig. 1 illu strates the apparatus a position whereby when the s indle 2 is revolved by turning the handle 34 neously to rise or fall, as desired according to the direction in which the handle 34 is turned.

To operate the uppersash 18 independently, (while the lower sash remains in a fixed position,) the spindle 2, with its pinion 12 attached thereto, is pushed inward until the and lower Window-sash having their adjoinside 36 of the flange touches the face 37 of the pinion 11, the pinion 13 being thus disengaged from the pinion 12, and simultaneously with such disengagement the pinion 13 is en- 'gaged and prevented from revolving by the pro ecting piece on the locking-plate 22, thereby locking the lower sash 19, the said plate 22 having changed its position owing to the flange 20 on the pinion 13 engaging in the slot 21 of the locking-plate 22 and slidin along the face 23 of the base-plate 10 Wit the pinion 12. The turning of'the handle 34 thenoperates the' upper sash in the desired direction. When it is desired to operate the lower sash 19 independently while the upper sash remains in a fixed position, a corre sponding 1process is followedviz., the spin dle 2, wit its pinion 12 attached thereto, is withdrawn outward until the face 38 of the flange 20 touches the side 39 of the pinion 13,

whi e theprojecting piece 24 on the lockingplate 22 engages the pinion 11, preventing it revolving and thereby locking the upper sash 18. The turning of the handle then operates the lower sash in the desired direction. When it is desired to preventthe sashes from being opened or closed by hand, the spindle 2 is revolved until the key 31 is in line with the slot 34*; The handle 34 is then removed, which permits the key 31 under the influence of the spiral spring to enga e in the slot 34*, preventing the rotation o the spindle, and thus retaining the upper and lower sashes in a fixed position.

Having now described our'invention, What we claim as new, and desire to secure by Letters Patent, is

1. A sash-fastener consisting of a baseplate having two pinions mounted thereon one at each end thereof, a larger pinion intermediate of the. outer two pinions mounted on a sliding spindle and divided into two portions by a central flange each one of said portions being adapted to mesh with a pinion respectively, a slotted locking-plate for said flange provided with projecting pieces adapted to engage said two pinions resectively, and means for rotatin and 100 'ng said sliding spindle substantia ly as and for i the purposes set forth.

2. A sash-fastener consisting of an upper the pinions 11 and 12 being thus disengaged,-

ing side rails each provided with a rack, a pinion meshing with each rack a middle pinion divided into two portions b a central flange mounted on a sliding spindlla, said portions being adapted to mesh with said two pinions res ectively, a slotted lockin -plate for said. pieces adapte 100 ng said sliding spindle, substantially, as and'for the purposes set forth.

3. A sash-fastener consisting of racks secured to the sash, pinions engaging'with said racks, a central pinion adapted to engage with the beforementioned pinions to rotate the same, a sliding spindle for said central pinion whereby said pinion may be moved out of engagement with either one of the be- 'forementioned pinions and a locking-plate havin a slot therein in which a part of the centra pinion engages to move said plate and projecting pieces'on said plate adapted to en age with the first-mentioned pinions to 100 the same against movement.

4. A sash-fastener consisting of racks secured to the sash, pinions 11 13 en agin with said racks, a central pinion 12 adapted to engage with the pinions 11 13 to rotate the same, a sliding spindle for the pinion '12 whereby said pinion may be moved out of engagement with either one of the pinions 11 13, means for locking the pinions 11 13 against movement and means for preventing movement of the sliding pinion, said means consisting of a key pivoted to the outer end of said spindle, said spindle having a channel in said end in which said key fits, a spring in said channel for forcing the key out of the channel, a washer having a slot therein and secured to the frame, said key engaging in said slot when forced out of the channel and a removable handle havin means thereon for keeping the key in its 0 annel, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribin Witnesses.
