SASH-LOCK CONSTRUCTION.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Application led October 22, 1920. Serial No. 418,841.

sey, have invented certain new and usefulV Improvements in `Sash-Lock Construction, of

- which the following is a .specication My invention relates to a sash lockconstructionV for windows whereby the sashes may readily be locked in closed position or may be permitted an unrestricted sliding movement, or a limited sliding movement, in relation to each other. In accordance with my invention a manipulative device is provided having several positions, in one of which the sashes are free to slide past 'each other for a limited, determined, distance only. Thus,it is possible to leave the window open for ventilation with the assurance that the limited amount of opening provided will not be suliicient to enable an intruder'to enter through the saine. A person on the outside may, oi course, reach through the opening and attempt to manipulate the locking device. `This will, however, avail him nothing vsince the locking device can only be so positioned as to permit moving the same into a position `in which the sashes have an unrestricted sliding movement, when the sashes are bothv entirely closed. This being the case a person on the outside can never etliect an openingsutiicientto admit his body without breaking the glass.

l' obtain -this result by providing one of the sashes with a vertical guideway which extends for a part only oi the height of the sash. The other sash is provided with a horizontal vopening therethrough in which is slidably mounted a spindlev having a head which may be alinedwith'the vertical guideway, only when the meeting rails of the two sashes are in meeting position. The arrangement is such that the head of the spindle cannot be removed Jfrom the guidein any way except by movement of the spindle through the horizontal opening reterred to. when the two sashes are entirely closed. The sash may be locked in closed position by moving .the head of the spindle into a socket which is alined therewith when the two sashes are entirely closed. The head ofthe spindle may also, when the sashes are closed, be moved into a .position in which unrestricted sliding movement of the sashes is permitted. Means are also provided for locking or holding the spindle in each of the three positions referred to.

In order that my invention may be more clearly understood attention is hereby directed to the accompanying drawings forming part of this application and illustrating one embodiment of my invention. 'In the drawings Figure 1 represents a front elevation of a window, viewedirom the inside of the room, Vand provided with my invention, Fig. 2 represents an enlarged vertical section taken on line 2 2 of Fig. l, Figs. 3 and 4 are partial sections similar to that shown in Fig. 2, showing the locking spindle in different positions, Fig. 5 represents a vertical section taken on line 5-5 of Fig. 2, Fig. 6 represents a partial vertical section taken on line 6 6 of Fig. 4, and Fig. 7 is a detail construction showing the lock barrel and escutcheon plate, partly in side elevation and partly in section.

Referring to the drawings, have illustrated a window having an upper sash 1 and a lower sash 2 slidably mounted in the usual manner in a frame or casing indicated at-S. The upper sash 1 is provided with a bottom rail 4L and the lower sash with a top rail 5, these rails meeting in the usual mann r, asindicated at the line 6, when the two sashes are closed.

*One of the vertical side-members or stiles of the upper sash is provided with a vertical guideway 7 which extends upwardly for a limited distance from the bottom rail of the sash. This guideway communicates at the bottom with a horizontal opening 8 which extends into rail 4- for a short distance. Rail 5 is provided with a horizontal opening `9 therethrough which alines with the opening 8 when rails 4 and 5 are in meeting position.

Opening 9 is provided at one of the upper corners of the frame of the lower sash, preferably on the line where the'rail and stile are joined together. In the preferred construction, a lock barrel 10 is mounted within opening 9, this barrel having a front ange l1. An escutcheon plate 12 is secured to the front or inner face of the rail, in front 50 l the guideway.

of flange 11, this plate having a forwardly extending sleeve portion 13 which is coaxial with barrel 10.

The lock spindle 14 is slidably mounted within barrel 10 and through a suitable opening in escutcheon plate 12. The spindle is provi-ded with a head 15 which is adapted to be alined with the guideway 7. Barrel 10 is provided at its rear, that is its outer end, with a key hole slot 16. The cylindrical or body portion of the spindle is slidably and rotatably mounted in the main or cylindrical portion of this slot, as well as in the opening referred to in escutcheon plate 12. The spindle is provided with laterally extending projections 17, 18 and 19, in alinement with each other. The key projections 17 and 18 are adapted to be passed through the vertical portions of the key hole slot, when the spindle is in proper position to aline these projections with the slot.

A knob 20 is provided having an annular flange 21 within which the forward end oli spindle 1,4 is received, the spindle and knob being secured together by a. screw 22. A sleeve 23 is provided which is secured to knob 20, preferably by ascrew-threaded engagement as shown. Sleeve 23 is slidably mounted on the collar or annular extension 13 of escutcheon plate 12. j

A spiral spring 24 is preferably positioned upon spindle 14, to press the same rearwardly, that is, outwardly of the window. This spring may be arranged to bear against escutcheon plate 12 at one end and against the key projection 19 on the spindle at the other end, as shown. rlhe opening 8 in sash 4 is preferably provided with a lining plate 25. Opening 8 is extended rearwardly as shown to form a socket 26 in which the head 15 may be received when the sashes are to be locked together in closed position.

The guideway 7 is preferably provided with a rear wall 27 and with Efront walls 28 between which a vertical slot 29 is provided of awidth s'uiiicient to permit the movement of spindle 14 up and down the same while the plates 28 prevent movement of head 15 forwardly past the same, when it is within The guideway is provided with a top wall 29, so that head 15 may only be removed from the guideway by closing the sashes to aline openings 8 and 9 so that head 15 may be moved horizontally below the lower end of flanges 28.

With the arrangement described, vwhen the sashes are closed as is shown in Fig. 2, knob 20 being in vertical position, key projections 17 and 18 will pass through key slot 16 and head 15 will enter socket 26, this movement bein caused by spring 24 if the knob is not helgd. In this position the sashes will be locked against any movement. rlhe spindle may be locked against removal from this position by turning the same into horizontal position, that is by turning the same through an angle of 45 degrees. In the construction shown in the drawings, the knob is turned to the right through an angle of 45 degrees whereupon key projection 19 will abut against a stop 30. The spindle cannot be withdrawn from this position until it is turned back to the vertical position, because of the fact that projection 18 is out of alinement with key slot 16.

When the sashes are to be given a limited amount of opening if the sashes have previously been entirely locked, the knob 2O` is drawn inwardly into the position in which head 15 is in alinement with guideway 7. In this position projection 17 y will be at the rear` of the key slot and projection 18 will Vbe immediately in Vfront olf the key slot.

Knob 2O may then be rotated 45 degrees to the right, as shown in Fig. 3, whereupon projection 18 will abut against stop 30 and the spindle `will be locked to the barrel by projections 17 and 18, which are positioned on opposite sides .of the bottom of the barrel. The position-in which head 15 alines with guideway 7 may readily `be indicated as by means of a circumferential groove or l mark 31 extending about the annular projection 13 of escutcheonplate12. The knob may be moved eitherA inwardly or outwardly, depending on its previous position,`

until the end ofV sleeve 23 alines with the groove or mark 31, whereupon the knob may be rotated into position tolock the spindle to the barrel as stated. Y

Vhen it is desired to have the sashes entl'ely fre@ to slide up and down, the sashes. f

being in closed position,'knob 2O .is drawn forwardly as far as it will'go, whereupon it is turned 45'degrees tothe rightVV into the position'shown in Fig. 4. In this position head 15 is infront of guideway 7 so that no obstruction is offered to the free movement of both sashes. The spindle is locked in this position by projection 17 on one side of the bottom of barrel 10 and the head 15 on the other side of the same.

It will be `noted from the above that the A l sashes may be kept open to the extent permitted by the guide slot while a greater amount of sliding movement. of the sashes is prevented by a manipulative device, the

position of which cannot bealtered except when both sashes are closed, and in that case, only from the inside. To move the spindle from any one of the three positions Y yinto any other onerof said positions, the two 1 which is ordinarily found at the rnortisedl connection between either stile and the bottom rail of the top sash, and the corresponding nail at the connection between the stile and the top rail of the bottom sash are taken out. rIhese nails are usually put in the sashes at the -mortise connections when the Same are being glued together.

The hole 9 is then bored through the rail 5 of the bottom sash, at the point at which the nail referred to was located. 'Ihis hole should then be counter-sunk to a depth equal to the thickness of barrel flange 11 and escutcheon plate 12. Barrel 10 is then mounted within opening 9 and fastened in position by a screw through flange 11 of the barrel. The spindle is then inserted through the barrel and through the key slot 16 whereupon spring 24 may be slipped over the spindle into engagement with projection 19. The front end of the spindle is then slipped through the opening in escutcheon plate 12 and the latter secured in position against the front .of rail 5. Flange 11 and plate 12 will lie in the counter-sunk opening at the front of the rail, so that plate 12 will-lie flush with the front of the rail.,

in which position it may readily be secured by Suitable screws.

The knob 2O may then be slipped on the front end of the spindle and fastened in position by screw 22. An opening 32 may be provided in the sleeve 23 through which screw 22may be dropped into position to` secure the same through the vspindle and into flange 21 of the knob, this being possible when the knob and spindleare pulled for- Fvardly to the extreme position shown in The horizontal opening 8 in rail 4 may then be bored, in position to aline with open- .ing 9, and the lining member 25 fastened in position by screws 33. The guide slot 7 is then rabbeted outV and the metallic guide slot member fastened in position by means of screws`34 which extend through the Vbottom portion 27 of the `metallic guide vslot member into the stile of the sash. f

The lock construction may very. readily be removed from the Sash by taking out the screws by which the escutcheon plate 12 is positioned, after which the knob is removed by unscrewing VScrew 22 through opening 32. The screw which holds barrel flange 11 in position is then removed which permits removing the entire lock construction from the sash rail 5. The spindle may then be slipped forwardly out of the barrel 10 whereupon the spring 24 may be removed.

It should be understood that my invention is not limited strictly to the details of construct-ion described but is as broad as is indicated by the accompanying claims.
